Sinonasal inverted papilloma and predictors of health-related quality of life after endonasal endoscopic surgery: A prospective cohort study. Clin Otolaryngol 2024. [PMID: 38613400 DOI: 10.1111/coa.14158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 02/06/2024] [Accepted: 03/17/2024] [Indexed: 04/14/2024]
Abstract
OBJECTIVES Existing knowledge on health-related quality of life (HRQoL) after surgical removal of sinonasal inverted papilloma (IP) is limited. Moreover, predictors for a better or worse post-operative HRQoL outcome are not known. Our aim was to assess HRQoL in all three health domains (physical, psychological, and social), track its post-operative trajectory, investigate if pre-operative observations could predict distinct post-operative HRQoL outcomes, and evaluate whether physicians' interventions could contribute to improved post-operative HRQoL. DESIGN Prospective cohort study. SETTING Tertiary referral hospital. PARTICIPANTS Seventy-four patients who underwent surgery for an IP were included. They were asked to fill in the Endonasal Endoscopic Sinus and Skull-Base Surgery Questionnaire (EES-Q) pre-operatively, and then 2 weeks, 3 months, and 1 year post-operatively. MAIN OUTCOME MEASURES Linear mixed models analyses were performed to evaluate the overall post-operative HRQoL and the separate health domains, as well as the impact of specific variables (sex, age, American Society of Anaesthesiologists [ASA] classification, smoker, Krouse staging, pre-operative EES-Q score, type of surgery, and post-operative antibiotics) on HRQoL improvement. RESULTS The total EES-Q score (p < .001) as well as the physical (p < .001), psychological (p = .049), and the social (p = .002) domains significantly improved post-operatively. ASA classification (p = .049), pre-operative EES-Q score (p < .001) and post-operative antibiotics (p = .036) were significant variables. CONCLUSIONS Overall HRQoL, as well as each of the three health domains, improved significantly. A higher ASA score, a higher pre-operative EES-Q score, and the administration of post-operative antibiotics were significant predictors for better HRQoL recovery post-operatively. Further research is necessary to confirm these results.

Reliability, costs, and radiation dose of dual-energy X-ray absorptiometry in diagnosis of radiologic sarcopenia in surgically menopausal women. Insights Imaging 2024; 15:104. [PMID: 38589691 PMCID: PMC11001834 DOI: 10.1186/s13244-024-01677-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 03/13/2024] [Indexed: 04/10/2024] Open
Abstract
OBJECTIVE The aim of this study was to evaluate and compare reliability, costs, and radiation dose of dual-energy X-ray absorptiometry (DXA) to MRI and CT in measuring muscle mass for the diagnosis of sarcopenia. METHODS Thirty-four consecutive DXA scans performed in surgically menopausal women from November 2019 until March 2020 were analyzed by two observers. Observers analyzed muscle mass of the lower limbs in every scan twice. Reliability was assessed by calculating inter- and intra-observer variability. Reliability from CT and MRI as well as radiation dose from CT and DXA were collected from literature. Costs for each type of scan were calculated according to the guidelines for economic evaluation of the Dutch National Health Care Institute. RESULTS The 34 participants had a median age of 58 years (IQR 53-65) and a median body mass index of 24.6 (IQR 21.7-29.7). Inter-observer variability had an intraclass correlation coefficient (ICC) of 0.997 (95% CI 0.994-0.998) with a relative variability of 0.037 ± 0.022%. Regarding intra-observer variability, observer 1 had an ICC of 0.998 (95% CI 0.996-0.999) with a relative variability of 0.019 ± 0.016% and observer 2 had an ICC of 0.997 (95% CI 0.993-0.998) with a relative variability of 0.016 ± 0.011%. DXA costs were €62, CT €77, and MRI €195. The estimated radiation dose of CT was 2.5-3.0 mSv, for DXA this was 2-4 µSv. CONCLUSIONS DXA has lower costs and a lower radiation dose, with low inter- and intra-observer variability, compared to CT and MRI for assessing lower limb muscle mass. TRIAL REGISTRATION Netherlands Trial Register; NL8068. CRITICAL RELEVANCE STATEMENT DXA is a good alternative for CT and MRI in assessing lower limb muscle mass, with lower costs and lower radiation dose, while inter-observer and intra-observer variability are low. KEY POINTS • Screening for sarcopenia should be optimized as the population ages. • DXA outperformed CT and MRI in the measured metrics. • DXA validity should be further evaluated as an alternative to CT and MRI for sarcopenia evaluation.

Different Frameworks, Similar Results? Head-to-Head Comparison of the Generic Preference-Based Health-Outcome Measures CS-Base and EQ-5D-5L. APPLIED HEALTH ECONOMICS AND HEALTH POLICY 2024; 22:227-242. [PMID: 37824057 PMCID: PMC10864418 DOI: 10.1007/s40258-023-00837-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 09/12/2023] [Indexed: 10/13/2023]
Abstract
OBJECTIVE We compared two generic, preference-based health-outcome measures: the novel patient-centered Château-Santé Base (CS-Base), entailing a multi-attribute preference response framework, and the widely used EQ-5D-5L, regarding effects of different measurement frameworks and different descriptive systems. METHODS We conducted a cross-sectional study using a random sample of patients (3019 reached, 1988 included) in the USA with various health conditions. The CS-Base (12 attributes, each with four levels), EQ-5D-5L and the 5D-4L (an ad hoc, multi-attribute preference response-based measure that includes five attributes similar to the EQ-5D-5L, but with four levels) were used as health-outcome measures. We compared the proportions of problems reported on health attributes, statistical robustness and face validity of coefficients, attribute importance, differentiation between health states based on health-state values obtained with these measures, and user experience. RESULTS All the CS-Base and 5D-4L coefficients had logical orders and significant differences from the reference level (p < 0.001). Substantial differences were observed in the CS-Base and 5D-4L coefficients between all levels on all attributes, while subtle differences were seen in those of the EQ-5D-5L. Attribute importance of usual (daily) activities were lowest or second lowest in all the three health-outcome measures. Attributes with the highest importance in the CS-Base, 5D-4L, and EQ-5D-5L were respectively mobility, anxiety/depression, and pain/discomfort. Four attributes are similar between the CS-Base and EQ-5D-5L, eight are exclusive to CS-Base. Of the eight, vision and hearing had the highest importance. Health-state values showed a smoother distribution with minimal discontinuity in the CS-Base and EQ-5D-5L than in the 5D-4L. In user experience evaluation, both CS-Base and the 5D-4L showed mean scores above 50 (indicating positive evaluation) in terms of the description of health and ease of understanding. CONCLUSIONS This study demonstrated that CS-Base and 5D-4L, which are grounded in the multi-attribute preference response framework, produced statistically robust coefficients, with better face validity than those for the EQ-5D-5L. CS-Base and the EQ-5D-5L outperformed the 5D-4L in differentiating between health states. Notwithstanding differences in content, measurement frameworks, and estimated coefficients, the computed health-state values were similar between CS-Base and EQ-5D-5L.

Impact of health-related behavioral factors on participation in a cervical cancer screening program: the lifelines population-based cohort. BMC Public Health 2023; 23:2376. [PMID: 38037016 PMCID: PMC10688458 DOI: 10.1186/s12889-023-17293-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Accepted: 11/22/2023] [Indexed: 12/02/2023] Open
Abstract
BACKGROUND Regular participation in cervical cancer screening is critical to reducing mortality. Although certain sociodemographic factors are known to be associated with one-time participation in screening, little is known about other factors that could be related to regular participation. Therefore, this study evaluated the association between health-related behavioral factors and regular participation in cervical cancer screening. METHODS The Lifelines population-based cohort was linked to data for cervical cancer screening from the Dutch Nationwide Pathology Databank. We included women eligible for all four screening rounds between 2000 and 2019, classifying them as regular (4 attendances), irregular (1-3 attendances), and never participants. Multinomial logistic regression was performed to evaluate the association between behavioral factors and participation regularity, with adjustment made for sociodemographic factors. RESULTS Of the 48,325 included women, 55.9%, 35.1%, and 9% were regular, irregular, and never screening participants. After adjustment for sociodemographic factors, the likelihood of irregular or never screening participation was increased by smoking, obesity, marginal or inadequate sleep duration, alcohol consumption and low physical activity, while it was decreased by hormonal contraception use. CONCLUSION An association exists between unhealthy behavioral factors and never or irregular participation in cervical cancer screening.

Abstract
BACKGROUND Most existing research studying health status impacted by morbidity has focused on a specific health condition, and most instruments used for measuring health status are neither patient-centered nor preference-based. This study aims to report on the health status of patients impacted by one or more health conditions, measured by a patient-centered and preference-based electronic patient-reported outcome measure. METHODS A cross-sectional study was conducted among patients with one or more health conditions in the United States. A novel generic, patient-centered, and preference-based electronic patient-reported outcome measure: Château Santé-Base, was used to measure health status. Individual health state was expressed as a single metric number (value). We compared these health-state values between sociodemographic subgroups, between separate conditions, between groups with or without comorbidity, and between different combinations of multimorbidity. RESULTS The total sample comprised 3913 patients. Multimorbidity was present in 62% of the patients. The most prevalent health conditions were pain (50%), fatigue/sleep problems (40%), mental health problems (28%), respiratory diseases (22%), and diabetes (18%). The highest (best) and lowest health-state values were observed in patients with diabetes and mental health problems. Among combinations of multimorbidity, the lowest values were observed when mental health problems were involved, the second lowest values were observed when fatigue/sleep problems and respiratory diseases coexisted. CONCLUSIONS This study compared health status across various single, and multiple (multimorbidity and comorbidity) health conditions directly, based on single metric health-state values. The insights are valuable in clinical practice and policy-making.

A care substitution service in the Netherlands: impact on referral, cost, and patient satisfaction. BMC PRIMARY CARE 2023; 24:171. [PMID: 37658285 PMCID: PMC10472548 DOI: 10.1186/s12875-023-02137-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 08/22/2023] [Indexed: 09/03/2023]
Abstract
BACKGROUND In care substitution services, medical specialists offer brief consultations to provide general practitioners (GPs) with advice on diagnosis, treatment, or hospital referral. When GPs serve as gatekeepers to secondary care, these regional services could reduce pressures on healthcare systems. The aim is to determine the impact of implementing a care substitution service for dermatology, orthopaedics, and cardiology on the hospital referral rate, health care costs, and patient satisfaction. METHODS A before-after study was used to evaluate hospital referral rates and health care costs during a follow-up period of 1 year. The study population comprised patients with eligible International Classification of Primary Care codes for referral to the care substitution service (only dermatology, orthopaedic, cardiology indications), as pre-defined by GPs and medical specialists. We compared referral rates before and after implementation by χ2 tests and evaluated patient preference by qualitative analysis. RESULTS In total, 4,930 patients were included, 2,408 before and 2,522 after implementation. The care substitution service decreased hospital referrals during the follow-up period from 15 to 11%. The referral rate decreased most for dermatology (from 15 to 9%), resulting in a cost reduction of €10.59 per patient, while the other two specialisms experienced smaller reductions in referral rates. Patients reported being satisfied, mainly because of the null cost, improved organisation, improved care, and positive experience of the consultation. CONCLUSIONS The care substitution service showed promise for specialisms that require fewer hospital facilities, as exemplified by dermatology.

Randomized controlled study of pain education in patients receiving radiotherapy for painful bone metastases. Radiother Oncol 2023; 185:109687. [PMID: 37169300 DOI: 10.1016/j.radonc.2023.109687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 04/26/2023] [Accepted: 04/27/2023] [Indexed: 05/13/2023]
Abstract
BACKGROUND Although short-course radiotherapy is an effective treatment for patients with painful bone metastases, pain is not always sufficiently controlled. We therefore investigated the additional effect of a nurse-led pain education program on pain control and quality of life (QoL). PATIENTS AND METHODS In this multicenter study, patients with solid tumor bone metastases and a worst pain intensity of ≥5 on a 0-10 numeric rating scale (NRS) were randomized between care as usual (control-group) and care as usual plus the Pain Education Program (PEP-group). PEP consisted of a structured interview and personalized education with follow-up phone calls. Patients completed the Brief Pain Inventory, EORTC QLQ-C15-PAL and BM22 at week 0, 1, 4, 8 and 12. The primary outcome was pain control, defined as the number of patients whose worst pain intensity was <5 on a 0-10 NRS after 12 weeks. Secondary outcomes were time to reach control of pain (NRS < 5), mean worst pain and average pain, and QoL at weeks 1, 4, 8 and 12. RESULTS Of 308 included patients, 182 (92 PEP-group) completed 12 weeks follow-up. At 12 weeks, more patients in the PEP-group (71%) compared to the control-group (52%) reported pain control (P =.008). In the PEP-group, pain control was reached earlier than in the control-group (median 29 days versus 56 days; P =.003). Mean worst and average pain decreased in both groups but decreased more in the PEP-group. QoL did not differ between the groups. CONCLUSION The addition of PEP to care as usual for patients treated with radiotherapy for painful bone metastases resulted in less pain and faster pain control.

Abstract
BACKGROUND Postoperative rehabilitation after primary total hip arthroplasty (p-THA) differs between the Netherlands and Germany. Aim is to compare clinical effectiveness and to get a first impression of cost effectiveness of Dutch versus German usual care after p-THA. METHODS A transnational prospective controlled observational trial. Clinical effectiveness was assessed with self-reported questionnaires and functional tests. Measurements were taken preoperatively and 4 weeks, 12 weeks, and 6 months postoperatively. For cost effectiveness, long-term economic aspects were assessed from a societal perspective. RESULTS 124 working-age patients finished the measurements. German usual care leads to a significantly larger proportion (65.6% versus 47.5%) of satisfied patients 12 weeks postoperatively and significantly better self-reported function and Five Times Sit-to-Stand Test (FTSST) results. German usual care is generally 45% more expensive than Dutch usual care, and 20% more expensive for working-age patients. A scenario analysis assumed that German patients work the same number of hours as the Dutch, and that productivity costs are the same. This analysis revealed German care is still more expensive but the difference decreased to 8%. CONCLUSIONS German rehabilitation is clinically advantageous yet more expensive, although comparisons are less straightforward as the socioeconomic context differs between the two countries. TRIAL REGISTRATION The study is registered in the German Registry of Clinical Trials (DRKS00011345, 18/11/2016).

Identification of a methylation panel as an alternative triage to detect CIN3+ in hrHPV-positive self-samples from the population-based cervical cancer screening programme. Clin Epigenetics 2023; 15:103. [PMID: 37322534 PMCID: PMC10273737 DOI: 10.1186/s13148-023-01517-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Accepted: 06/03/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND The Dutch population-based cervical cancer screening programme (PBS) consists of primary high-risk human papilloma virus (hrHPV) testing with cytology as triage test. In addition to cervical scraping by a general practitioner (GP), women are offered self-sampling to increase participation. Because cytological examination on self-sampled material is not feasible, collection of cervical samples from hrHPV-positive women by a GP is required. This study aims to design a methylation marker panel to detect CIN3 or worse (CIN3+) in hrHPV-positive self-samples from the Dutch PBS as an alternative triage test for cytology. METHODS Fifteen individual host DNA methylation markers with high sensitivity and specificity for CIN3+ were selected from literature and analysed using quantitative methylation-specific PCR (QMSP) on DNA from hrHPV-positive self-samples from 208 women with CIN2 or less (< CIN2) and 96 women with CIN3+. Diagnostic performance was determined by area under the curve (AUC) of receiver operating characteristic (ROC) analysis. Self-samples were divided into a train and test set. Hierarchical clustering analysis to identify input methylation markers, followed by model-based recursive partitioning and robustness analysis to construct a predictive model, was applied to design the best marker panel. RESULTS QMSP analysis of the 15 individual methylation markers showed discriminative DNA methylation levels between < CIN2 and CIN3+ for all markers (p < 0.05). The diagnostic performance analysis for CIN3+ showed an AUC of ≥ 0.7 (p < 0.001) for nine markers. Hierarchical clustering analysis resulted in seven clusters with methylation markers with similar methylation patterns (Spearman correlation> 0.5). Decision tree modeling revealed the best and most robust panel to contain ANKRD18CP, LHX8 and EPB41L3 with an AUC of 0.83 in the training set and 0.84 in the test set. Sensitivity to detect CIN3+ was 82% in the training set and 84% in the test set, with a specificity of 74% and 71%, respectively. Furthermore, all cancer cases (n = 5) were identified. CONCLUSION The combination of ANKRD18CP, LHX8 and EPB41L3 revealed good diagnostic performance in real-life self-sampled material. This panel shows clinical applicability to replace cytology in women using self-sampling in the Dutch PBS programme and avoids the extra GP visit after a hrHPV-positive self-sampling test.

The effect of extended participation windows on attendance at cervical cancer screening. Prev Med Rep 2023; 32:102166. [PMID: 36926594 PMCID: PMC10011428 DOI: 10.1016/j.pmedr.2023.102166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 02/21/2023] [Accepted: 02/22/2023] [Indexed: 03/03/2023] Open
Abstract
Research has long since confirmed the benefits of regular cervical cancer screening (CCS) worldwide. However, some developed countries have low participation rates despite well-organized screening programs. Given that studies in Europe typically define participation in 12-month windows from an invitation, we evaluated both whether extending this defined time window could reveal the true participation rate and how sociodemographic determinants affect participation delays. This involved linking data from the Lifelines population-based cohort with CCS-related data from the Dutch Nationwide Pathology Databank and including data for 69 185 women eligible for screening in the Dutch CCS program between 2014 and 2018. We then estimated and compared the participation rates for 15- and 36-month time windows and categorized women by the primary screening window into timely participation (within 15 months) and delayed participation (within 15-36 months) groups, before performing multivariable logistic regression to evaluate the association between delayed participation and the sociodemographic determinants. Participation rates for the 15- and 36-month windows were 71.1% and 77.0%, respectively, with participation considered timely in 49 224 cases and delayed in 4047 cases. Delayed participation was associated with age 30-35 years (odds ratio [OR]: 2.88, 95 %CI: 2.67-3.11), higher education (OR: 1.50, 95 %CI: 1.35-1.67), the high-risk human papillomavirus test-based program (OR: 1.67, 95 %CI: 1.56-1.79), and pregnancy (OR: 4.61, 95 %CI: 3.88-5.48). These findings show that a 36-month window for monitoring attendance at CCS better reflects the actual participation rate by accommodating possible delayed uptake among younger, pregnant, and highly educated women.

Abstract
PURPOSE This study reports on survival and health related quality of life (HRQOL) after extracorporeal membrane oxygenation (ECMO) treatment and the associated costs in the first year. MATERIALS AND METHODS Prospective observational cohort study patients receiving ECMO in the intensive care unit during August 2017 and July 2019. We analyzed all healthcare costs in the first year after index admission. Follow-up included a HRQOL analysis using the EQ-5D-5L at 6 and 12 months. RESULTS The study enrolled 428 patients with an ECMO run during their critical care admission. The one-year mortality was 50%. Follow up was available for 124 patients at 12 months. Survivors reported a favorable mean HRQOL (utility) of 0.71 (scale 0-1) at 12 months of 0.77. The overall health status (VAS, scale 0-100) was reported as 73.6 at 12 months. Mean total costs during the first year were $204,513 ± 211,590 with hospital costs as the major factor contributing to the total costs. Follow up costs were $53,752 ± 65,051 and costs of absenteeism were $7317 ± 17,036. CONCLUSIONS At one year after hospital admission requiring ECMO the health-related quality of life is favorable with substantial costs but considering the survival might be acceptable. However, our results are limited by loss of follow up. So it may be possible that only the best-recovered patients returned their questionnaires. This potential bias might lead to higher costs and worse HRQOL in a real-life scenario.

Abstract
Objective Social functioning is an important factor in the evaluation of postoperative health-related quality of life (HRQoL) for pituitary adenoma patients. In a prospective cohort study multidimensional HRQoL of non-functioning (NFA) and functioning (FA) pituitary adenoma patients were evaluated following endoscopic endonasal surgery using the endoscopic endonasal sinus and skull base surgery questionnaire (EES-Q). Methods Prospectively, 101 patients were included. The EES-Q was completed preoperatively and postoperatively (2 weeks, 3 months, 1 year). Sinonasal complaints were completed daily during the first week postoperatively. Preoperative and postoperative scores were compared. A generalized estimating equation (uni- and multivariate) analysis was performed to identify significant HRQoL changes related to selected covariates. Results Two weeks postoperatively, physical (p < .05) and social (p < .05) HRQoL are worse and psychological (p < .05) HRQoL improved compared with preoperatively. Three months postoperatively, psychological HRQoL (p = .01) trended back to baseline and no differences in physical or social HRQoL were reported. One year postoperatively, psychological (p = .02) and social (p = .04) HRQoL improved while physical HRQoL remained stable. FA patients report a worse HRQoL preoperatively (social, p < .05) and 3 months postoperatively (social, p < .02 and psychological, p < .02). Sinonasal complaints peak in the first days postoperatively and gradually return to presurgical levels 3 months postoperatively. Conclusions The EES-Q provides meaningful information on multidimensional HRQoL to improve patient-centred health care. Social functioning remains the most difficult area in which to achieve improvements. Despite the relatively modest sample size, there is some indication that the FA group continues to show a downward trend (and thus improvement) even after 3 months, when most other parameters reach stability. Level of evidence Level II-B.

Patients with the genetic blistering skin condition epidermolysis bullosa (EB) report severe pain as a consequence of skin and mucous membrane lesions including blisters, wounds, and scars. Adequate symptom alleviation is not often achieved using conventional pharmacologic interventions. Finding novel approaches to pain care in EB is imperative to improve the quality of life of patients living with EB. There are several anecdotal reports on the use of cannabinoid-based medicines (CBMs) by EB patients to reduce the burden of symptoms. However, controlled clinical investigations assessing these reported effects are lacking. As the pain quality "unpleasantness" delineates EB pain, we hypothesize the modulation of affective pain processing in the brain by way of intervention with CBMs comprising the cannabinoids Δ-9-tetrahydrocannabinol and cannabidiol-objectified by functional magnetic resonance imaging (fMRI). The C4EB study is an investigator-initiated, single-centre, randomized, double-blind, placebo-controlled and crossover trial. Adult patients with the diagnosis epidermolysis bullosa, reporting chronic pain will be eligible to participate. Following baseline measurements, participants will be randomized to receive the sublingually administered interventions placebo and Transvamix® in forward or reversed orders, each for two weeks and separated by a washout. The primary outcome is the difference in numeric rating scale pain scores between grouped interventions, using affective descriptors within the Short-form McGill Pain Questionnaire-2. Secondary outcomes include pain self-efficacy, concomitant analgesic medication-use and adverse events. Additionally, fMRI will be employed to assess brain connectivity related to neuroanatomic pain circuits at baseline, placebo and Transvamix® interventions. The study was approved by the ethical committee at the University Medical Center of Groningen in the Netherlands. Results will be submitted for publication in a peer-reviewed journal. Trial registration number: Netherlands Trial Register: NL9347 (Acronym: C4EB).

Extending the use of the Endoscopic Endonasal Sinus and Skull Base Surgery Questionnaire in a cross-sectional study: Patients with chronic rhinosinusitis versus healthy controls. Clin Otolaryngol 2022; 47:634-640. [PMID: 35821620 PMCID: PMC9796423 DOI: 10.1111/coa.13962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2021] [Revised: 05/18/2022] [Accepted: 05/29/2022] [Indexed: 01/01/2023]
Abstract
OBJECTIVES There are several instruments to assess health-related quality of life (HRQoL) in chronic rhinosinusitis (CRS). Unfortunately, none of them evaluates all three health domains (physical, social and psychological) important to assess the overall well-being of the patient. The Endoscopic Endonasal Sinus and Skull Base Surgery Questionnaire (EES-Q) does assess all these elements. Initially, the EES-Q is validated to evaluate the impact of endoscopic endonasal surgery (EES) on HRQoL. The aim of this study is to assess whether EES-Q outcomes differ in patients with CRS compared with healthy individuals. Therefore, extending the use of the EES-Q for all CRS patients. DESIGN Cross-sectional study. SETTING Tertiary referral hospital. PARTICIPANTS One hundred patients with uncontrolled CRS (50% with nasal polyps) scheduled to receive EES. The questionnaire was completed preoperatively. Healthy control subjects (n = 100) without any history of sinusitis or a known current medical treatment at a hospital were included. MAIN OUTCOME MEASURES Mann-Whitney U test was performed to identify differences in EES-Q scores (domain scores and EES-Q score). RESULTS The median EES-Q score in CRS patients (33.8) was significantly higher (p < 0.001) than in the control group (10.4). As well as the physical (52.5 vs. 16.4, p < 0.001), psychological (13.8 vs. 5.0, p < 0.001) and social (37.5 vs. 2.5, p < 0.001) domain scores. CONCLUSIONS With this study, we are extending the use of the EES-Q. It indicates that the EES-Q can be a valuable clinical tool to assess multidimensional HRQoL in all patients with CRS.

Abstract
OBJECTIVES To improve continence care in the Netherlands, a new framework has been developed in which a shift has been made from incontinence severity as the sole criterion for selecting incontinence products to a focus on patient need for daily life activities. The impact of the framework on daily care has not been assessed. We aimed to compare treatment effectiveness and costs between participants who did and did not undergo re-evaluation according to the new framework. DESIGN Cohort study SETTING: Twelve pharmacies in the Netherlands PARTICIPANTS: Existing users of absorbent incontinence materials for urinary incontinence. INTERVENTIONS Participants were offered the option to have their incontinence products re-evaluated within the new framework at their pharmacy. PRIMARY AND SECONDARY OUTCOME MEASURES Effectiveness and cost outcomes were assessed at 3 and 6 months through questionnaires. These questionnaires included the International Consultation on Incontinence Questionnaire (ICIQ) Lower Urinary Tract Symptoms Quality of Life Module, ICIQ Urinary Incontinence Short Form, ICIQ Absorbent Pads, questions about satisfaction and the iPCQ and iMCQ. RESULTS 303 users consented and 279 completed the baseline questionnaire. Of these participants, 72 agreed to a re-evaluation of their incontinence materials. There was a small improvement at 3 months in the re-evaluation group compared with the other group on most outcomes. However, these improvements were not clinically relevant. Moreover, these differences did not change much from 3 to 6 months. Small differences were also observed in the changes in costs, but with very wide CIs on both sides of zero (€99.38; 95% CI -633.48 to 832.23). CONCLUSIONS The current study showed no clinically relevant effect of a newly implemented framework for selecting incontinence materials in pharmacies when compared with an existing method. Given that the study also showed no differences in effectiveness and costs, introducing the new framework in pharmacies may not lead to better incontinence care.

Assessment of the Benefits and Cost-Effectiveness of Population-Based Breast Cancer Screening in Urban China: A Model-Based Analysis. Int J Health Policy Manag 2022; 11:1658-1667. [PMID: 34273933 PMCID: PMC9808213 DOI: 10.34172/ijhpm.2021.62] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 05/30/2021] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND To decrease the burden of breast cancer (BC), the Chinese government recently introduced biennial mammography screening for women aged 45-70 years. In this study, we assess the effectiveness and cost-effectiveness of implementing this programme in urban China using a micro-simulation model. METHODS The 'Simulation Model on radiation Risk and breast cancer Screening' (SiMRiSc) was applied, with parameters updated based on available data for the Chinese population. The base scenario was biennial mammography screening for women aged 45-70 years, and this was compared to a reference population with no screening. Seven alternative scenarios were then simulated by varying the screening intervals and participant ages. This analysis was conducted from a societal perspective. The discounted incremental cost-effectiveness ratio (ICER) was compared to a threshold of triple the gross domestic product (GDP) per life years gained (LYG), which was 30 785 USD/LYG. Univariate sensitivity analyses were conducted to evaluate model robustness. In addition, a budget impact analysis was performed by comparing biennial screening with no screening at a time horizon of 10 years. RESULTS Compared with no screening, the base scenario was cost-effective in urban China, giving a discounted average cost-effectiveness ratio (ACER) of 17 309 USD/LYG. The model was most sensitive to the cost of mammography per screen, followed by mean size of self-detected tumours, mammographic breast density and the cumulative lifetime risk of BC. The efficient frontier showed that at a threshold of 30 785 USD/LYG, the base scenario was the optimal scenario with a discounted ICER of 25 261 USD/LYG. Over 10 years, screening would incur a net cost of almost 38.1 million USD for a city with 1 million citizens. CONCLUSION Compared to no screening, biennial mammography screening for women aged from 45-70 is cost-effective in urban China.

Abstract
OBJECTIVE Health care expenditures for children with functional constipation (FC) are high, while conservative management is successful in only 50% of the children. The aim is to evaluate whether adding physiotherapy to conventional treatment (CT) is a cost-effective strategy in the management of children with FC aged 4-18 years in primary care. METHODS A cost-effectiveness analysis was performed alongside a randomized controlled trial (RCT) with 8-month follow-up. Costs were assessed from a societal perspective, effectiveness included both the primary outcome (treatment success defined as the absence of FC and no laxative use) and the secondary outcome (absence of FC irrespective of laxative use). Uncertainty was assessed by bootstrapping and cost-effectiveness acceptability curves (CEACs) were displayed. RESULTS One hundred and thirty-four children were randomized. The incremental cost-effectiveness ratio (ICER) for one additional successfully treated child in the physiotherapy group compared with the CT group was €24,060 (95% confidence interval [CI] €-16,275 to €31,390) and for the secondary outcome €1,221 (95% CI €-12,905 to €10,956). Subgroup analyses showed that for children with chronic laxative use the ICER was €2,134 (95% CI -24,975 to 17,192) and €571 (95% CI 11 to 3,566), respectively. At a value of €1,000, the CEAC showed a probability of 0.53 of cost-effectiveness for the primary outcome, and 0.90 for the secondary outcome. CONCLUSIONS Physiotherapy added to CT as first-line treatment for all children with FC is not cost-effective compared with CT alone. Future studies should consider the cost-effectiveness of physiotherapy added to CT in children with chronic laxative use. TRIAL REGISTRATION The RCT is registered in the Netherlands Trial Register (NTR4797), on the 8th of September 2014. The first child was enrolled on the 2nd of December 2014. https://www.trialregister.nl/trial/4654.

Abstract
BACKGROUND Wound healing and scar formation depends on a plethora of factors. Given the impact of abnormal scar formation, interventions aimed to improve scar formation would be most advantageous. The tissue stromal vascular fraction (tSVF) of adipose tissue is composed of a heterogenous mixture of cells embedded in extracellular matrix. It contains growth factors and cytokines involved in wound-healing processes, eg, parenchymal proliferation, inflammation, angiogenesis, and matrix remodeling. OBJECTIVES The aim of this study was to investigate the hypothesis that tSVF reduces postsurgical scar formation. METHODS This prospective, double-blind, placebo-controlled, randomized trial was conducted between 2016 and 2020. Forty mammoplasty patients were enrolled and followed for 1 year. At the end of the mammoplasty procedure, all patients received tSVF in the lateral 5 cm of the horizontal scar of 1 breast and a placebo injection in the contralateral breast to serve as an intrapatient control. Primary outcome was scar quality measure by the Patient and Observer Scar Assessment Scale (POSAS). Secondary outcomes were obtained from photographic evaluation and histologic analysis of scar tissue samples. RESULTS Thirty-four of 40 patients completed follow-up. At 6 months postoperation, injection of tSVF had significantly improved postoperative scar appearance as assessed by the POSAS questionnaire. No difference was observed at 12 months postoperation. No improvement was seen based on the evaluation of photographs and histologic analysis of postoperative scars between both groups. CONCLUSIONS Injection of tSVF resulted in improved wound healing and reduced scar formation at 6 months postoperation, without any noticeable advantageous effects seen at 12 months.

Abstract
Objective To assess the cost‐effectiveness of app‐based treatment for female stress, urgency or mixed urinary incontinence (UI) compared with care‐as‐usual in Dutch primary care. Design A pragmatic, randomised controlled, superiority trial. Setting Primary care in the Netherlands from 2015 to 2018, follow‐up at 12 months. Population Women with ≥2 UI‐episodes per week, access to mobile apps, wanting treatment. Methods The standalone app included conservative management for UI with motivation aids (e.g. reminders). Care‐as‐usual delivered according to the Dutch GP guideline for UI. Main outcome measures Costs and cost‐effectiveness and ‐utility were assessed from a societal perspective, based on incontinence impact adjusted life years (IIALYs), quality adjusted life years (QALYs) and medical, non‐medical and productivity costs. Information on costs was obtained with the iMCQ and iPCQ questionnaires (medical consumption and productivity cost questionnaires). Results In all, 262 women were andomised equally to app or care‐as‐usual; 89 (68%) and 83 (63%) attended follow‐up, respectively. Costs were lower for app‐based treatment with € −161 (95% confidence interval [CI −180 to −151) per year. Cost‐effectiveness showed small mean differences in effect for IIALY (0.04) and QALY (−0.03) and thus larger incremental cost‐effectiveness ratios (ICER: −€3696) and incremental cost‐utility ratios (ICUR: €6379). Conclusion App‐based treatment is a cost‐effective alternative to care‐as‐usual for women with UI in Dutch primary care. Tweetable abstract App‐treatment for female urinary incontinence cost‐effective compared to care‐as‐usual in general practice after 12 months. App‐treatment for female urinary incontinence cost‐effective compared to care‐as‐usual in general practice after 12 months.

Abstract
BACKGROUND Autologous lipofilling is an emerging procedure to treat and possibly reverse dermal scars and to reduce scar-related pain, but its efficacy and mechanisms are poorly understood. OBJECTIVES The aim of this study was to test the hypothesis that repeated lipografts reverse dermal scars by reinitiation of wound healing. METHODS In a prospective, non-placebo-controlled clinical study, 27 adult patients with symptomatic scars were given 2 lipofilling treatments at 3-month intervals. As primary outcome, clinical effects were measured with the Patient and Observer Scar Assessment Scale (POSAS). Scar biopsies were taken before and after treatments to assess scar remodeling at a cellular level. RESULTS Twenty patients completed the study. Patients' scars improved after lipofilling. The total POSAS scores (combined patient and observer scores) decreased from 73.2 [14.7] points (mean [standard deviation]) pretreatment to 46.1 [14.0] and 32.3 [13.2] points after the first and second lipofilling treatment, respectively. Patient POSAS scores decreased from 37.3 [8.8] points to 27.2 [11.3] and 21.1 [11.4] points, whereas observer POSAS scores decreased from 35.9 [9.5] points to 18.9 [6.0] and 11.3 [4.5] points after the first and second treatment, respectively. After each lipofilling treatment, T lymphocytes, mast cells, and M2 macrophages had invaded scar tissue and were associated with increased vascularization. In addition, the scar-associated epidermis showed an increase in epidermal cell proliferation to levels similar to that normal in skin. Moreover, lipofilling treatment caused normalization of the extracellular matrix organization towards that of normal skin. CONCLUSIONS Autologous lipofilling improves the clinical outcome of dermal scars through the induction of a pro-regenerative immune response, increased vascularization, and epidermal proliferation and remodeling of scar tissue extracellular matrix.

Abstract
OBJECTIVES Knowledge on long-term outcomes in patients with Hirschsprung disease is progressing. Nevertheless, differences in outcomes according to aganglionic lengths are unclear. We compared long-term bowel function and generic quality of life in Hirschsprung patients with total colonic or long-segment versus rectosigmoid aganglionosis. METHODS In this nationwide, cross-sectional study participants with proven Hirschsprung disease received the Defecation and Fecal Continence questionnaire, and the Child Health Questionnaire Child Form-87, or the WHO Quality of Life-100. We excluded deceased patients, patients who were younger than 8 years, lived abroad, had a permanent enterostomy, or were intellectually impaired. RESULTS The study population (n = 334) was operated for rectosigmoid (83.9%), long-segment (8.7%), or total colonic aganglionosis (7.5%). Fecal incontinence in general was not significantly different between the three groups, but liquid fecal incontinence was significantly associated with total colonic aganglionosis (odds ratio [OR] = 6.00, 95% confidence interval [CI] 2.07-17.38, P = 0.001). Regarding constipation, patients with total colonic or long-segment aganglionosis were less likely to suffer from constipation than the rectosigmoid group (OR = 0.21, 95% CI, 0.05-0.91, P = 0.038 and OR = 0.11, 95% CI, 0.01-0.83, P = 0.032). Quality of life was comparable between the three groups, except for a lower physical score in children with total colonic aganglionosis (P = 0.016). CONCLUSIONS Over time Hirschsprung patients with total colonic or long-segment aganglionosis do not suffer from worse fecal incontinence in general. A difference in stool consistency may underlie the association between liquid fecal incontinence and total colonic aganglionosis and constipation in patients with rectosigmoid aganglionosis. Despite these differences, generic quality of life is comparable on reaching adulthood.

Abstract
INTRODUCTION Familial occurrence of Hirschsprung's disease may have a positive effect on patients' ability to cope with the disease. The aim was to compare long-term bowel function and generic quality of life between patients with familial and non-familial Hirschsprung's disease. METHODS This was a nationwide, cross-sectional study in which we included all 830 Hirschsprung patients of 8 years and older who had undergone surgery between 1957 and 2015. We excluded patients with a permanent stoma, intellectual disability, or an unknown or foreign address. We requested patients to complete the validated pediatric or adult Defecation and Fecal Continence questionnaire and the Child Health Questionnaire Child Form-87, or the World Health Organization Quality of Life-100 Assessment Instrument. RESULTS We analyzed 336 Hirschsprung patients, 15.8% of whom were familial cases and 84.2% were non-familial cases. After adjusting for aganglionic length, sex, and age, patients with familial Hirschsprung's disease were twice more likely to suffer from constipation (OR = 2.47, 95% CI, 1.21-5.05, p = 0.013). The quality of life of the pediatric patients was comparable, but in adult patients the energy/fatigue, thinking/learning/concentration, and work capacity facets showed better scores in the familial patients with Hirschsprung's disease of the rectosigmoid (p = 0.029, p = 0.024, p = 0.036, respectively). CONCLUSIONS Different facets of generic quality of life are better in adult patients with familial Hirschsprung's disease of the rectosigmoid. It seems that familial experience with the disease influences patients' coping abilities positively.

Cost-effectiveness of abbreviated-protocol MRI screening for women with mammographically dense breasts in a national breast cancer screening program. Breast 2021; 61:58-65.

Abstract
Introduction Magnetic resonance imaging (MRI) has shown the potential to improve the screening effectiveness among women with dense breasts. The introduction of fast abbreviated protocols (AP) makes MRI more feasible to be used in a general population. We aimed to investigate the cost-effectiveness of AP-MRI in women with dense breasts (heterogeneously/extremely dense) in a population-based screening program. Methods A previously validated model (SiMRiSc) was applied, with parameters updated for women with dense breasts. Breast density was assumed to decrease with increased age. The base scenarios included six biennial AP-MRI strategies, with biennial mammography from age 50–74 as reference. Fourteen alternative scenarios were performed by varying screening interval (triennial and quadrennial) and by applying a combined strategy of mammography and AP-MRI. A 3% discount rate for both costs and life years gained (LYG) was applied. Model robustness was evaluated using univariate and probabilistic sensitivity analyses. Results The six biennial AP-MRI strategies ranged from 132 to 562 LYG per 10,000 women, where more frequent application of AP-MRI was related to higher LYG. The optimal strategy was biennial AP-MRI screening from age 50–65 for only women with extremely dense breasts, producing an incremental cost-effectiveness ratio of € 18,201/LYG. At a threshold of € 20,000/LYG, the probability that the optimal strategy was cost-effective was 79%. Conclusion Population-based biennial breast cancer screening with AP-MRI from age 50–65 for women with extremely dense breasts might be a cost-effective alternative to mammography, but is not an option for women with heterogeneously dense breasts. AP-MRI can be cost-effective for screening women with extremely dense breast. The more frequent the use of AP-MRI, the more life years will be gained. Biennial AP-MRI for women with extremely dense breast up to age 65 is optimal.

Abstract
BACKGROUND Costs associated with extracorporeal membrane oxygenation (ECMO) are an important factor in establishing cost effectiveness. In this systematic review, we aimed to determine the total hospital costs of ECMO for adults. METHODS The literature was retrieved from the PubMed/MEDLINE, EMBASE, and Web of Science databases from inception to 4 March 2020 using the search terms 'extracorporeal membrane oxygenation' combined with 'costs'; similar terms or phrases were then added to the search, i.e. 'Extracorporeal Life Support' or 'ECMO' or 'ECLS' combined with 'costs'. We included any type of study (e.g. randomized trial or observational cohort) evaluating hospital costs of ECMO in adults (age ≥18 years). RESULTS A total of 1768 unique articles were retrieved during our search. We assessed 74 full-text articles for eligibility, of which 14 articles were selected for inclusion in this review; six papers were from the US, five were from Europe, and one each from Japan, Australia, and Taiwan. The sample sizes ranged from 16 to 18,684 patients. One paper exclusively used prospective cost data collection, while all other papers used retrospective data collection. Five papers reported charges instead of costs. There was large variation in hospital costs, ranging from US$22,305 to US$334,608 (2019 values), largely depending on the indication for ECMO support and location. The highest reported costs were for lung transplant recipients who were receiving ECMO support in the US, and the lowest reported costs were for extracorporeal cardiopulmonary resuscitation patients presenting with non-shockable rhythm in Japan. The additional costs of ECMO patients compared with non-ECMO patients varied between US$2518 and US$200,658. Personnel costs varied between 11 and 52% of the total amount. CONCLUSIONS ECMO therapy is an advanced and expensive technology, although reported costs differ considerably depending on ECMO indication and whether charges or costs are measured. Combined with the ongoing gathering of outcome data, cost effectiveness per ECMO indication could be determined in the future.

Abstract
BACKGROUND Acute gastroenteritis is a common childhood condition with substantial medical and indirect costs, mostly because of referral, hospitalisation, and parental absence from work. AIM To determine the cost-effectiveness of adding oral ondansetron to care as usual (CAU) for children with acute gastroenteritis presenting to out-of-hours primary care (OOH-PC). DESIGN AND SETTING A pragmatic randomised controlled trial from December 2015 to January 2018, at three OOHPC centres in the north of the Netherlands (Groningen, Zwolle, and Assen) with a follow-up of 7 days. METHOD Children were recruited at the OOH-PC and parents kept a parental diary. Inclusion criteria were: aged 6 months-6 years; diagnosis of acute gastroenteritis; at least four reported episodes of vomiting 24 hours before presentation, at least one of which was in the 4 hours before presentation; and written informed consent from both parents. Children were randomly allocated at a 1:1 ratio to either CAU (oral rehydration therapy) or CAU plus one dose of 0.1 mg/kg oral ondansetron. RESULTS In total, 194 children were included for randomisation. One dose of oral ondansetron decreased the proportion of children who continued vomiting within the first 4 hours from 42.9% to 19.5%, (a decrease of 54.5%), with an odds ratio of 0.4 (95% confidence interval [CI] = 0.2 to 0.7; number needed to treat: four). Total mean costs in the ondansetron group were 31.2% lower (€488 [£420] versus €709 [£610]), and the total incremental mean costs for an additional child free of vomiting in the first 4 hours was -€9 (£8) (95% CI = -€41 [£35] to €3 [£3]). CONCLUSION A single oral dose of ondansetron for children with acute gastroenteritis, given in OOH-PC settings, is both clinically beneficial and cost-effective.

Preferences and Experiences Regarding the Use of the Self-Sampling Device in hrHPV Screening for Cervical Cancer. PATIENT-PATIENT CENTERED OUTCOMES RESEARCH 2021; 15:245-253. [PMID: 34558035 PMCID: PMC8866331 DOI: 10.1007/s40271-021-00550-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Accepted: 09/07/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND To improve participation in the Dutch cervical cancer screening, a self-sampling device (SSD) was introduced in 2017 into the Dutch population-based screening programme (PBS) for the early detection of cervical cancer. The aim of this study was to gather potential preferences and experiences that might influence a woman's decision to use the SSD in the Dutch PBS. METHODS A scoping review was performed in the PubMed database. Studies that assessed preferences and experiences of women regarding the SSD were included, and preferences and experiences were extracted. In addition, in a qualitative study, the list of potential preferences and experiences specific for the Dutch PBS was extended based on semi-structured interviews with SSD users as well as non-SSD users who recently participated in the PBS, analysed in a structured manner by translating full sentences to key words. RESULTS Ninety-eight studies were included in the scoping review and 16 interviews were performed. Frequently mentioned reasons for using the SSD, in both the interviews and the literature, were practicality and comfort. Frequently mentioned reasons for not using the SSD were fear of not performing the SSD procedure correctly and doubts on whether the results of the high-risk human papillomavirus (hrHPV) test will be reliable. A new positive experience elicited in the interviews was accessibility. Negative preferences and experiences were not being aware the SSD was an option, and the inconvenience that after an hrHPV-positive test result of the SSD, an additional smear test at the GP is necessary. CONCLUSION Several preferences and experiences play a role in the choice whether or not to use the SSD. Based on the currently found preferences and experiences, an app will be developed in order to assess which of these are the most important for women participating in the Dutch population-based cervical screening programme.

Abstract
Objective To assess the long‐term effectiveness of app‐based treatment for female stress, urgency or mixed urinary incontinence (UI) compared with care‐as‐usual in primary care. Design A pragmatic, randomised controlled, superiority trial. Setting Primary care in the Netherlands from 2015 to 2018, follow up at 12 months. Population Women with two or more UI episodes per week and access to mobile apps, wanting treatment. A total of 262 women were randomised equally to app or care‐as‐usual; 89 (68%) and 83 (63%) attended 1 year follow up. Interventions The standalone app included conservative management for UI with motivation aids (e.g. reminders). Care‐as‐usual was delivered according to the Dutch GP guideline for UI. Main outcome measures Effectiveness assessed by the change in symptom severity score (ICIQ‐UI‐SF) and the change in quality of life (ICIQ‐LUTSqol) with linear regression on an intention‐to‐treat basis. Results Clinically relevant improvement of UI severity for both app (−2.17 ± 2.81) and care‐as‐usual (−3.43 ± 3.6) groups, with a non‐significant mean difference of 0.903 (−0.66 to 1.871). Conclusion App‐based treatment is a viable alternative to care‐as‐usual for UI in primary care in terms of effectiveness after 1 year. Tweetable abstract App‐based treatment for female urinary incontinence is a viable alternative to care‐as‐usual after 12 months. App‐based treatment for female urinary incontinence is a viable alternative to care‐as‐usual after 12 months. Linked article: See related article at https://doi.org/10.1111/1471‐0528.17191.

The Addition of Tissue Stromal Vascular Fraction to Platelet-Rich Plasma Supplemented Lipofilling Does Not Improve Facial Skin Quality: A Prospective Randomized Clinical Trial. Aesthet Surg J 2021; 41:NP1000-NP1013.

Abstract
BACKGROUND Lipofilling has become popular as a treatment to improve aging-related skin characteristics (eg, wrinkles, pigmentation spots, pores, or rosacea). Different additives such as platelet-rich plasma (PRP) or stromal vascular fraction (SVF) have been combined with lipofilling to increase the therapeutic effect of adipose-derived stromal cells (ASCs). OBJECTIVES The aim of this study was to examine the hypothesis that mechanically isolated SVF augments the therapeutic effect of PRP-supplemented lipofilling to improve facial skin quality. METHODS This prospective, double-blind, placebo-controlled, randomized trial was conducted between 2016 and 2019. In total, 28 female subjects were enrolled; 25 completed the follow-up. All patients received PRP-supplemented lipofilling with either mechanically isolated SVF or saline. SVF was isolated by fractionation of adipose tissue (tSVF). Results were evaluated by changes in skin elasticity and transepidermal water loss, changes in skin-aging-related features, ie, superficial spots, wrinkles, skin texture, pores, vascularity, and pigmentation, as well as patient satisfaction (FACE-Q), recovery, and number of complications up to 1 year postoperative. RESULTS The addition of tSVF to PRP-supplemented lipofilling did not improve skin elasticity, transepidermal water loss, or skin-aging-related features. No improvement in patient satisfaction with overall facial appearance or facial skin quality was seen when tSVF was added to PRP-supplemented lipofilling. CONCLUSIONS In comparison to PRP-supplemented lipofilling, PRP-supplemented lipofilling combined with tSVF does not improve facial skin quality or patient satisfaction in a healthy population. PRP-supplemented lipofilling combined with tSVF can be considered a safe procedure. LEVEL OF EVIDENCE: 2

Abstract
Objective To evaluate the costs and non‐inferiority of a strategy starting with the levonorgestrel intrauterine system (LNG‐IUS) compared with endometrial ablation (EA) in the treatment of heavy menstrual bleeding (HMB). Design Cost‐effectiveness analysis from a societal perspective alongside a multicentre randomised non‐inferiority trial. Setting General practices and gynaecology departments in the Netherlands. Population In all, 270 women with HMB, aged ≥34 years old, without intracavitary pathology or wish for a future child. Methods Randomisation to a strategy starting with the LNG‐IUS (n = 132) or EA (n = 138). The incremental cost‐effectiveness ratio was estimated. Main outcome measures Direct medical costs and (in)direct non‐medical costs were calculated. The primary outcome was menstrual blood loss after 24 months, measured with the mean Pictorial Blood Assessment Chart (PBAC)‐score (non‐inferiority margin 25 points). A secondary outcome was successful blood loss reduction (PBAC‐score ≤75 points). Results Total costs per patient were €2,285 in the LNG‐IUS strategy and €3,465 in the EA strategy (difference: €1,180). At 24 months, mean PBAC‐scores were 64.8 in the LNG‐IUS group (n = 115) and 14.2 in the EA group (n = 132); difference 50.5 points (95% CI 4.3–96.7). In the LNG‐IUS group, 87% of women had a PBAC‐score ≤75 points versus 94% in the EA group (relative risk [RR] 0.93, 95% CI 0.85–1.01). The ICER was €23 (95% CI €5–111) per PBAC‐point. Conclusions A strategy starting with the LNG‐IUS was cheaper than starting with EA, but non‐inferiority could not be demonstrated. The LNG‐IUS is reversible and less invasive and can be a cost‐effective treatment option, depending on the success rate women are willing to accept. Tweetable abstract Treatment of heavy menstrual bleeding starting with LNG‐IUS is cheaper but slightly less effective than endometrial ablation. Treatment of heavy menstrual bleeding starting with LNG‐IUS is cheaper but slightly less effective than endometrial ablation.

Abstract
Aim This study explored the attitudes of medical professionals to organ and tissue donation in paediatric intensive care units (PICUs) and neonatal intensive care units (NICUs) in the Netherlands. It also examined their compliance with the existing Dutch donation protocol and assessed whether a paediatric donation protocol was needed. Methods We invited 966 professionals working in all eight PICUs and the two largest NICUs to complete an online survey from December 2016 until April 2017. Results A quarter (25%) took part and they included PICU intensivists, neonatologists, nurses and other health and allied professionals. Most were female and nurses. More than half (54%) of the PICU respondents considered paediatric organ donation to be very important and 53% supported tissue donation. In contrast, only 22% of the NICU respondents believed that both neonatal organ and tissue donation were very important. Familiarity and compliance with the existing national donation protocol were low. PICU nurses had significantly less experience than PICU intensivists and felt less comfortable with the donation process. None of the NICU respondents had prior donation experience. Conclusion Paediatric intensive care units and NICU professionals lack specialised knowledge and experience on organ and tissue donation. A comprehensive and clear paediatric donation protocol is clearly needed.

A Randomized Trial of Initiation of Chronic Noninvasive Mechanical Ventilation at Home vs In-Hospital in Patients With Neuromuscular Disease and Thoracic Cage Disorder: The Dutch Homerun Trial. Chest 2020; 158:2493-2501. [PMID: 32682770 DOI: 10.1016/j.chest.2020.07.007] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 06/30/2020] [Accepted: 07/02/2020] [Indexed: 10/23/2022] Open
Abstract
BACKGROUND There is an increasing demand for home mechanical ventilation (HMV) in patients with chronic respiratory insufficiency. At present, noninvasive ventilation is exclusively initiated in a clinical setting at all four centers for HMV in the Netherlands. In addition to its high societal costs and patient discomfort, commencing HMV is often delayed because of a lack of hospital bed capacity. RESEARCH QUESTION Is HMV initiation at home, using a telemonitoring approach, noninferior to in-hospital initiation in a nationwide study? STUDY DESIGN AND METHODS We conducted a nationwide, randomized controlled noninferiority trial, in which every HMV center recruited 24 patients (home [n = 12] vs hospital [n = 12]) with a neuromuscular disease or thoracic cage disorder, all with an indication to start HMV. Change in arterial CO2 (Paco2) over a 6-month period was considered the primary outcome, and quality of life and costs were assessed as secondary outcomes. RESULTS A total of 96 patients were randomized, most of them diagnosed with neuromuscular disease. We found a significant improvement in Paco2 within both groups (home: from 6.1 to 5.6 kPa [P < .01]; hospital: from 6.3 to 5.6 kPa [P < .01]), with no significant differences between groups. Health-related quality of life showed significant improvement on various subscales; however, no significant differences were observed between the home and hospital groups. From a societal perspective, a cost reduction of more than €3,200 ($3,793) per patient was evident in the home group. INTERPRETATION This nationwide, multicenter study shows that HMV initiation at home is noninferior to hospital initiation, as it shows the same improvement in gas exchange and health-related quality of life. In fact, from a patient's perspective, it might even be a more attractive approach. In addition, starting at home saves over €3,200 ($3,793) per patient over a 6-month period.

Abstract
BACKGROUND In many countries, medical interventions are reimbursed on the basis of recommendations made by advisory boards and committees that apply multiple criteria in their assessment procedures. Given the diversity of these criteria, it is difficult to find common ground to determine what information is required for setting priorities. OBJECTIVE To investigate whether society and patients share the same interests and views concerning healthcare priorities. METHODS We applied a framework of discrete choice models in which respondents were presented with judgmental tasks to elicit their preferences. They were asked to choose between two hypothetical scenarios of patients receiving a new treatment. The scenarios graphically presented treatment outcomes and patient characteristics. Responses were collected through an online survey administered among respondents from the general population (N = 1,253) and patients (N = 1,389) and were analyzed using conditional logit and mixed logit models. RESULTS The respondents' preferences regarding new medical treatments revealed that they attached the most relative importance to additional survival years, age at treatment, initial health condition, and the cause of disease. Minor differences in the relative importance assigned to three criteria: age at treatment, initial health, and cause of disease were found between the general population and patient samples. Health scenarios in which patients had higher initial health-related quality of life (i.e., a lower burden of disease) were favored over those in which patients' initial health-related quality of life was lower. CONCLUSIONS Overall, respondents within the general population expressed preferences that were similar to those of the patients. Therefore, priority-setting studies that are based on the perspectives of the general population may be useful for informing decisions on reimbursement and other types of priority-setting processes in health care. Incorporating the preferences of the general population may simultaneously increase public acceptance of these decisions.

Abstract
BACKGROUND Mental health problems often arise in childhood and adolescence and can have detrimental effects on people's quality of life (QoL). Therefore, it is of great importance for clinicians, policymakers and researchers to adequately measure QoL in children. With this review, we aim to provide an overview of existing generic measures of QoL suitable for economic evaluations in children with mental health problems. METHODS First, we undertook a meta-review of QoL instruments in which we identified all relevant instruments. Next, we performed a systematic review of the psychometric properties of the identified instruments. Lastly, the results were summarized in a decision tree. RESULTS This review provides an overview of these 22 generic instruments available to measure QoL in children with psychosocial and or mental health problems and their psychometric properties. A systematic search into the psychometric quality of these instruments found 195 suitable papers, of which 30 assessed psychometric quality in child and adolescent mental health. CONCLUSIONS We found that none of the instruments was perfect for use in economic evaluation of child and adolescent mental health care as all instruments had disadvantages, ranging from lack of psychometric research, no proxy version, not being suitable for young children, no age-specific value set for children under 18, to insufficient focus on relevant domains (e.g. social and emotional domains).

Abstract
OBJECTIVES To evaluate at which sensitivity digital breast tomosynthesis (DBT) would become cost-effective compared to digital mammography (DM) in a population breast cancer screening program, given a constant estimate of specificity. METHODS In a microsimulation model, the cost-effectiveness of biennial screening for women aged 50-75 was simulated for three scenarios: DBT for women with dense breasts and DM for women with fatty breasts (scenario 1), DBT for the whole population (scenario 2) or maintaining DM screening (reference). For DM, sensitivity was varied depending on breast density from 65 to 87%, and for DBT from 65 to 100%. The specificity was set at 96.5% for both DM and DBT. Direct medical costs were considered, including screening, biopsy and treatment costs. Scenarios were considered to be cost-effective if the incremental cost-effectiveness ratio (ICER) was below €20,000 per life year gain (LYG). RESULTS For both scenarios, the ICER was more favourable at increasing DBT sensitivity. Compared with DM screening, 0.8-10.2% more LYGs were found when DBT sensitivity was at least 75% for scenario 1, and 4.7-18.7% when DBT sensitivity was at least 80% for scenario 2. At €96 per DBT, scenario 1 was cost-effective at a DBT sensitivity of at least 90%, and at least 95% for scenario 2. At €80 per DBT, these values decreased to 80% and 90%, respectively. CONCLUSION DBT is more likely to be a cost-effective alternative to mammography in women with dense breasts. Whether DBT could be cost-effective in a general population highly depends on DBT costs. KEY POINTS • DBT could be a cost-effective screening modality for women with dense breasts when its sensitivity is at least 90% at a maximum cost per screen of €96. • DBT has the potential to be cost-effective for screening all women when sensitivity is at least 90% at a maximum cost per screen of €80. • Whether DBT could be used as an alternative to mammography for screening all women is highly dependent on the cost of DBT per screen.

Abstract
RATIONALE & OBJECTIVE Patients with chronic kidney disease (CKD) are particularly sensitive to dietary sodium. We evaluated a self-management approach for dietary sodium restriction in patients with CKD. STUDY DESIGN Randomized controlled trial. SETTING & PARTICIPANTS Nephrology outpatient clinics in 4 Dutch hospitals. 99 adults with CKD stages 1 to 4 or a functioning (estimated glomerular filtration rate≥25mL/min/1.73m2) kidney transplant, hypertension, and sodium intake>130mmol/d. INTERVENTION Routine care was compared with routine care plus a web-based self-management intervention including individual e-coaching and group meetings implemented over a 3-month intervention period, followed by e-coaching over a 6-month maintenance period. OUTCOMES Primary outcomes were sodium excretion after the 3-month intervention and after the 6-month maintenance period. Secondary outcomes were blood pressure, proteinuria, costs, quality of life, self-management skills, and barriers and facilitators for implementation. RESULTS Baseline estimated glomerular filtration rate was 55.0±22.0mL/min/1.73m2. During the intervention period, sodium excretion decreased in the intervention group from 188±8 (SE) to 148±8mmol/d (P<0.001), but did not change significantly in the control group. At 3 months, mean sodium excretion was 24.8 (95% CI, 0.1-49.6) mmol/d lower in the intervention group (P=0.049). At 3 months, systolic blood pressure (SBP) decreased in the intervention group from 140±3 to 132±3mm Hg (P<0.001), but was unchanged in the control group. Mean difference in SBP across groups was-4.7 (95% CI, -10.7 to 1.3) mm Hg (P=0.1). During the maintenance phase, sodium excretion increased in the intervention group, but remained lower than at baseline at 160±8mmol/d (P=0.01), while it decreased in the control group from 174±9 at the end of the intervention period to 154±9mmol/d (P=0.001). Consequently, no difference in sodium excretion between groups was observed after the maintenance phase. There was no difference in SBP between groups after the maintenance phase. LIMITATIONS Limited power, postrandomization loss to follow-up, Hawthorne effect, lack of dietary data, short-term follow-up. CONCLUSIONS A coaching intervention reduced sodium intake at 3 months. Efficacy during the maintenance phase was diminished, possibly due to inadvertent adoption of the intervention by the control group.

Clinical- and Cost-Effectiveness of a Mandibular Advancement Device Versus Continuous Positive Airway Pressure in Moderate Obstructive Sleep Apnea. J Clin Sleep Med 2019; 15:1477-1485. [PMID: 31596213 PMCID: PMC6778341 DOI: 10.5664/jcsm.7980] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2019] [Revised: 06/07/2019] [Accepted: 06/07/2019] [Indexed: 12/29/2022]
Abstract
STUDY OBJECTIVES Limited evidence exists on the cost-effectiveness of mandibular advancement device (MAD) compared to continuous positive airway pressure (CPAP) therapy in moderate obstructive sleep apnea (OSA). Therefore, this study compares the clinical and cost-effectiveness of MAD therapy with CPAP therapy in moderate OSA. METHODS In a multicentre randomized controlled trial, patients with an apnea-hypopnea index (AHI) of 15 to 30 events/h were randomized to either MAD or CPAP. Incremental cost-effectiveness and cost-utility ratios (ICER/ICUR, in terms of AHI reduction and quality-adjusted life-years [QALYs, based on the EuroQol Five-Dimension Quality of Life questionnaire]) were calculated after 12 months, all from a societal perspective. RESULTS In the 85 randomized patients (n = 42 CPAP, n = 43 MAD), AHI reduction was significantly greater with CPAP (median reduction AHI 18.3 [14.8-22.6] events/h) than with MAD therapy (median reduction AHI 13.5 [8.5-18.4] events/h) after 12 months. Societal costs after 12 months were higher for MAD than for CPAP (mean difference €2.156). MAD was less cost-effective than CPAP after 12 months (ICER -€305 [-€3.003 to €1.572] per AHI point improvement). However, in terms of QALY, MAD performed better than CPAP after 12 months (€33.701 [-€191.106 to €562.271] per QALY gained). CONCLUSIONS CPAP was more clinically effective (in terms of AHI reduction) and cost-effective than MAD. However, costs per QALY was better with MAD as compared to CPAP. Therefore, CPAP is the first-choice treatment option in moderate OSA and MAD may be a good alternative. CLINICAL TRIAL REGISTRATION Registry: ClinicalTrials.gov; Identifier: NCT01588275.

A Scoping Review of Key Health Items in Self-Report Instruments Used Among Solid Organ Transplant Recipients. PATIENT-PATIENT CENTERED OUTCOMES RESEARCH 2019; 12:171-181. [PMID: 30324230 PMCID: PMC6397139 DOI: 10.1007/s40271-018-0335-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 01/07/2023]
Abstract
The overall aim of this scoping review of the literature is twofold: (1) to provide an overview of all instruments that have been used to assess health-related quality of life (HRQoL) after solid organ transplantation and (2) to provide a list of health items they include to support future studies on the development of a new-generation HRQoL instrument. All studies that administered any form of HRQoL instrument to post-transplant solid organ recipients were identified in a comprehensive search of PubMed (MEDLINE), Embase, and Web of Science, with a cut-off date of May 2018. The search used various combinations of the following keywords: lung, heart, liver, kidney, or pancreas transplantation; quality of life; well-being; patient-reported outcome; instrument; questionnaire; and health survey. In total, 8013 distinct publications were identified and 1218 of these were selected for review. Among the instruments applied, 53 measured generic, 51 organ-specific, 271 domain-specific, and 43 transplant-specific HRQoL. A total of 78 distinct health items grouped into 16 sub-domains were identified and depicted graphically. The majority of publications did not report a logical rationale for the choice of specific HRQoL instrument. The most commonly used types of instruments were generic health instruments, followed by domain-specific instruments. Despite the availability of transplant-specific instruments, few studies applied these types of instruments. Based on the 78 items, further research is planned to develop a patient-centered, transplant-specific HRQoL instrument that is concise, easy to apply (mobile application), and specifically related to the health issues of solid organ recipients.

Valuing Health Status in the First Year of Life: The Infant Health-Related Quality of Life Instrument. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2019; 22:721-727. [PMID: 31198190 DOI: 10.1016/j.jval.2018.12.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2018] [Revised: 12/07/2018] [Accepted: 12/17/2018] [Indexed: 05/21/2023]
Abstract
OBJECTIVES Efforts to evaluate HRQoL and calculate quality-adjusted life years (QALYs) for infants less than 12 months of age are hampered by the lack of preference-based HRQoL instruments for this group. To fill this gap, we developed the Infant Quality of life Instrument (IQI), which is administered through a mobile application. This article explains how weights were derived for the 4 levels of each health item. METHODS The IQI includes 7 health items: sleeping, feeding, breathing, stooling/poo, mood, skin, and interaction. In an online survey, respondents from the general population (n = 1409) and primary caregivers (n = 1229) from China, the United Kingdom, and the United States were presented with 10 discrete choice scenarios. Coefficients for the item levels were obtained with a conditional logit model. RESULTS The highest coefficients were found for sleeping, feeding, and breathing. All coefficients for these items were negative and logically ordered, meaning that more extreme levels were less preferred. Stooling, mood, skin, and interaction showed some irregularities in the ordering of coefficients. Results for caregivers and the general population were about the same. CONCLUSIONS The IQI is the first generic instrument to assess overall HRQoL in infants up to 1 year of age. It is short and easy to administer through a mobile application. We demonstrated how to derive values for infant health states with a discrete choice methodology. Our next step will be to normalize these values into utilities ranging from 0 (dead) to 1 (best health state) and to collect IQI values in a clinical population.

Patient-Centered Item Selection for a New Preference-Based Generic Health Status Instrument: CS-Base. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2019; 22:467-473. [PMID: 30975398 DOI: 10.1016/j.jval.2018.12.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Revised: 11/14/2018] [Accepted: 12/18/2018] [Indexed: 06/09/2023]
Abstract
OBJECTIVES To develop patient-centered health content for a novel generic instrument (Château Santé Base [CS-Base]) that is suitable to generate values for health status. METHODS Candidate items were drawn from existing health frameworks of generic health status instruments and placed in a diagram (HealthFANTM, Zeist, the Netherlands). Through an online survey, patients with a wide range of diseases were asked to select the 9 items that were most important to them. The importance of the items for the whole study group was determined by means of frequency distributions. RESULTS After handling duplicates and overlap, the remaining set of 47 items was placed in the HealthFAN. Among the 2256 Dutch patients who started the survey, the most common diagnoses were neck and back pain, diabetes, and asthma/chronic obstructive pulmonary disease. The 5 health items mentioned most frequently as most important were pain, personal relationships, fatigue, memory, and vision. Hearing and vision, anxiety and depression, and independence and self-esteem seemed highly intertwined, so we chose to pair these items. CONCLUSIONS A total of 12 health items were included in CS-Base. Its content is largely based on patient input and enables classification of patients' health status. CS-Base can be administered by means of an app on a mobile phone, which makes it a convenient and attractive tool for patients and researchers.

Health-related quality of life and well-being health state values among Dutch oldest old. Patient Prefer Adherence 2019; 13:721-728. [PMID: 31190754 PMCID: PMC6522649 DOI: 10.2147/ppa.s193171] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Accepted: 02/23/2019] [Indexed: 11/23/2022] Open
Abstract
Background: Valuing hypothetical health states is a demanding personal process, since it involves the psychological evaluation of hypothetical health states. It seems plausible that elderly individuals will value hypothetical health states differently than the general population. It is, however, important to understand the psychological division that oldest old subgroups construct between acceptable and unacceptable health states. This information can produce important evidence regarding well-being and disability conceptualization. Objective: To investigate how Dutch oldest old, conceptualize health-related quality of life health states when compared to well-being health states. In addition, we aim to compare subgroups, based on dependency classification. Methods: Ninety-nine elderly living in the Groningen, Hoogeveen and Veendam areas of the Netherlands participated in the study. Respondents were classified into three groups based on dependency levels. The respondents were asked to value hypothetical health states, a generic preference-based HRQoL and a well-being instrument, using a visual analog scale. Results: All three groups ranked the same health states, from both questionnaires, below the average across the health states. The health-related quality of life health states was consistently ranked lower than the current well-being health states. Conclusions: Health state valuations performed by the oldest old indicate that conceptually, respondents view below average health-related and well-being health states as undesirable. The results indicated that the oldest old do view deficits in health-related health states as more important than deficits in well-being health states. Since the oldest old performed the valuations, focused interventions to improve below average health-related outcomes might be the most cost-effective way to increase oldest old well-being outcomes.

A descriptive system for the Infant health-related Quality of life Instrument (IQI): Measuring health with a mobile app. PLoS One 2018; 13:e0203276. [PMID: 30169510 PMCID: PMC6118381 DOI: 10.1371/journal.pone.0203276] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Accepted: 08/19/2018] [Indexed: 11/23/2022] Open
Abstract
Background The assessment of health-related quality of life (HRQoL) is important for health outcomes research, disease modeling studies and comparisons of different healthcare interventions. Yet, only a few tools are available to assess HRQoL in 0-1-year-old infants. Furthermore, there is a need for an instrument able to assess HRQoL with a single, standardized, overall score in the first year of life. Here we described the development of the Infant health-related Quality of life Instrument (IQI), a generic, preference-based instrument that can be administered through a mobile application for assessing HRQoL in 0-1-year-old infants. Methods A multi-step development process began by extracting candidate health concepts from relevant measures identified by two literature searches. Next, three panels, with experts from Asia, Europe, New Zealand and United States of America, and two surveys, with primary caregivers in New Zealand, Singapore, and the United Kingdom, evaluated the relevance of the candidate health concepts, organized them into attributes based on their similarities, explored alternative attributes and generated response scales. Additional interviews assessed the cross-cultural interpretability, parents’ understanding of health attributes, and the usability of the mobile application. Results The final list of 7 health attributes included in the IQI consisted of sleeping, feeding, breathing, stooling/poo, mood, skin, and interaction. The users’ experiences with the mobile application were generally positive. Conclusions The IQI is the first generic, preference-based, instrument designed to assess overall HRQoL in 0-1-year old infants. It is short and easy-to-administer through a mobile application. Moreover, close attention was paid to the opinions of the infants’ primary caregivers during the instrument and mobile application development process.

Risk of cardiac tachyarrhythmia in patients with repaired tetralogy of Fallot: a multicenter cardiac MRI based study. Int J Cardiovasc Imaging 2018; 35:143-151. [PMID: 30094564 DOI: 10.1007/s10554-018-1435-9] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2018] [Accepted: 08/02/2018] [Indexed: 11/24/2022]
Abstract
Cardiac tachyarrhythmias are the leading cause of morbidity and mortality in patients with repaired tetralogy of Fallot (TOF). We evaluated risk factors for sustained ventricular tachyarrhythmia (VT) and atrial tachyarrhythmia (ATA) in these patients. Patients (n = 319) who underwent cardiac magnetic resonance (CMR) imaging at two tertiary centers between 2007 and 2016 were assessed. Potential risk markers, based on history, cardiac magnetic resonance imaging (CMR), electrocardiography (ECG) and echocardiography, were analyzed for prediction of the primary endpoint of VT, and the secondary endpoint of ATA. During a follow-up of 3.5 (0.9-6.1) years, 20 (6.3%) patients reached the primary endpoint, and 30 (9.4%) the secondary endpoint. Multivariable cox hazards regression identified right ventricular (RV) end-diastolic volume (Hazard ratio [HR] 2.03, per 10 ml/m2 increase; p = 0.02), RV end-systolic volume (HR 3.04, per 10 ml/m2 increase; p = 0.04), RV mass (HR 1.88, per 10 g/m2 increase; p = 0.02), and RV ejection fraction (HR 6.06, per 10% decrease; p = 0.02) derived from CMR to be independent risk factors of VT. In addition, QRS-duration (HR 1.70, per 10 ms increase; p = 0.001) and body mass index (BMI: HR 1.8, per 5 kg/m2 increase; p = 0.02) were independent markers of VT. Older age at TOF repair (HR 1.33, per 2 months increase; p = 0.03) and BMI (HR 1.76, per 5 kg/m2 increase; p < 0.001) independently predicted ATA. RV systolic dysfunction, hypertrophy and dilatation on CMR, together with QRS prolongation, and obesity are predictive of VT in TOF patients. Older age at TOF repair and obesity were associated with the occurrence of ATA.

Physiotherapy plus conventional treatment versus conventional treatment only in the treatment of functional constipation in children: design of a randomized controlled trial and cost-effectiveness study in primary care. BMC Pediatr 2018; 18:249. [PMID: 30064408 PMCID: PMC6069950 DOI: 10.1186/s12887-018-1231-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2018] [Accepted: 07/19/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Our aim was to design a study to evaluate the effectiveness and cost-effectiveness of adding physiotherapy to conventional treatment for children with functional constipation in primary care. Physiotherapy is focusing on improving the coordination between the pelvic floor and abdominal musculature during bowel movement, while conventional treatment is mainly focusing on symptomatic relief of symptoms, therefore, we expect the effects of physiotherapy will be more sustainable than the effects of conventional treatment. In this paper we describe the final study design and how the design was adapted, to overcome recruitment problems. METHODS We designed a randomized controlled trial of children aged 4-17 years with functional constipation diagnosed by a general practitioner or pediatrician. Children in the intervention group received physiotherapy plus conventional treatment, and those in the control group received conventional treatment only. Follow-up measurements took place at 4 and 8 months. The primary outcome was treatment success defined according to the Rome-III criteria as the absence of functional constipation, with no laxative use. Secondary outcomes were absence of functional constipation irrespective of laxative use, quality of life, global perceived effect, and costs. Children were recruited from September 2014 to February 2017. Initially, we aimed to include children with recent symptom onset. However, in the first phase of enrollment we were confronted with an unforeseen recruitment problem: many children and their parents refused randomization because physiotherapy was considered too burdensome for the stage of disease. Therefore, we decided to also include children with a longer duration of symptoms. In total 134 children were included. DISCUSSION The target number of participants is achieved. Therefore, the results may change thinking about the management of functional constipation in children. TRAIL REGISTRATION Netherlands Trial Register ( NTR4797 ), registered 8 September 2014.

Value judgment of health interventions from different perspectives: arguments and criteria. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2018; 16:16. [PMID: 29692687 PMCID: PMC5905114 DOI: 10.1186/s12962-018-0099-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2017] [Accepted: 04/09/2018] [Indexed: 01/07/2023] Open
Abstract
Background The healthcare sector is evolving while life expectancy is increasing. These trends put greater pressure on healthcare resources, prompt healthcare reforms, and demand transparent arguments and criteria to assess the overall value of health interventions. There is no consensus on the core criteria by which to value and prioritize interventions, and individual stakeholders might value specific elements differently. The present study is based on a literature review that retrieved the most widely recognized arguments and criteria used in decision-making. The aim was to compile a smaller set of arguments and criteria that would seem most relevant to different stakeholders. Methods A literature review was performed in Medline and EMBASE. The initial search retrieved over 2000 articles and documents of relevant committees. A selection was made based on their reference to healthcare, policy issues, or social justice. Finally, 84 papers were included. Data extraction took place after appraisal of the articles. A full table was made, including all arguments and criteria found; next, identical or largely overlapping arguments were excluded. The remaining arguments and criteria were assessed for relevance and a reduced set was compiled. Results The final set included 25 arguments and criteria, categorized by type (clinical, social justice, ethical, and policy). For each argument and criterion, relevance to stakeholders was scored on three levels (not, partly, and completely relevant). Conclusions Many arguments and criteria play a role in making value judgments on health interventions, but not all are relevant to all interventions. Moreover, they may interact with each other. A viable way to deal with interacting and possibly conflicting arguments and criteria might be to arrange public discussions that would evoke different stakeholders’ perspectives.

Molecular imaging with positron emission tomography and computed tomography (PET/CT) for selecting first-line targeted treatment in metastatic breast cancer: a cost-effectiveness study. Oncotarget 2018; 9:19836-19846. [PMID: 29731987 PMCID: PMC5929430 DOI: 10.18632/oncotarget.24869] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2017] [Accepted: 02/24/2018] [Indexed: 12/11/2022] Open
Abstract
Our aim was to evaluate the potential cost-effectiveness of PET/CT with FES and 89Zr-trastuzumab compared to pathology to select first-line targeted treatment in metastatic breast cancer (MBC) patients with non-rapidly progressive disease. A previously published and validated model was extended and adapted for this analysis. Two alternative scenarios were compared. In the care as usual pathway first-line targeted treatment of MBC patients was assigned on the basis of pathology results, while in the intervention pathway treatment selection was based on the results from the PET/CT imaging. Costs, life years gained (LYG) and incremental cost-effectiveness ratios (ICER) were calculated. More MBC lesions were detected in the intervention pathway than in the care as usual pathway. The diagnostic costs to evaluate the receptor status and the treatment costs were higher in the intervention strategy, as were total costs and total LYG. The ICER for replacing biopsies with PET/CT imaging with FES and 89Zr-trastuzumab, assuming sensitivity of 77.1% and specificity of 80%, ranged from €71,000 to €77,000 per LYG. When assuming sensitivity of 80% and specificity of 76.7%, the ICER for replacing biopsies with PET/CT imaging with FES and 89Zr-trastuzumab ranged from to €74,000 to €80,000 per LYG. The application of PET/CT with FES and 89Zr-trastuzumab in first-line treatment selection for MBC patients has the potential to be a cost-effective intervention. Our analysis demonstrated that even a small increase in the sensitivity and the specificity of PET/CT can have a large impact on its potential cost-effectiveness.

The impact of a mobile application-based treatment for urinary incontinence in adult women: Design of a mixed-methods randomized controlled trial in a primary care setting. Neurourol Urodyn 2018; 37:2167-2176. [PMID: 29392749 DOI: 10.1002/nau.23507] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2017] [Revised: 11/29/2017] [Accepted: 12/25/2017] [Indexed: 02/06/2023]
Abstract
AIMS We aim to assess whether a purpose-developed mobile application (app) is non-inferior regarding effectiveness and cost-effective when used to treat women with urinary incontinence (UI), as compared to care as usual in Dutch primary care. Additionally, we will explore the expectations and experiences of patients and care providers regarding app usage. METHODS A mixed-methods study will be performed, combining a pragmatic, randomized-controlled, non-inferiority trial with an extensive process evaluation. Women aged ≥18 years, suffering from UI ≥ 2 times per week and with access to a smartphone or tablet are eligible to participate. The primary outcome will be the change in UI symptom scores at 4 months after randomization, as assessed by the International Consultation on Incontinence Modular Questionnaire UI Short Form. Secondary outcomes will be the change in UI symptom scores at 12 months, as well as the patient-reported global impression of improvement, quality of life, change in sexual functioning, UI episodes per day, and costs at 4 and 12 months. In parallel, we will perform an extensive process evaluation to assess the expectations and experiences of patients and care providers regarding app usage, making use of interviews, focus group sessions, and log data analysis. CONCLUSION This study will assess both the effectiveness and cost-effectiveness of app-based treatment for UI. The combination with the process evaluation, which will be performed in parallel, should also give valuable insights into the contextual factors that influence the effectiveness of such a treatment.
