Effect of Treatment Preference in Randomized Controlled Trials: Systematic Review of the Literature and Meta-Analysis

Patient and physician preferences for treatment of hepatitis C virus infection in Japan: a discrete choice experiment

AIMS

This study was performed to evaluate patients' and physicians' preferences regarding hepatitis C virus (HCV) treatment in Japan, particularly focusing on direct-acting antivirals. Understanding these preferences is important for maintaining adherence to treatment necessary for achieving HCV elimination.

METHODS

A discrete choice experiment was conducted to identify patients' and physicians' preferences for HCV treatment in Japan. Eligible participants completed a preference survey via an online questionnaire. Eight attributes and their respective levels - pertaining to dosing regimen/schedule, safety, and out-of-pocket costs - were identified. The primary and secondary endpoints were the relative attribute importance (RAI) and utility value of attribute levels, which were compared between patients and physicians to highlight differences.

RESULTS

Both patients (n = 95) and physicians (n = 118) showed the greatest concern for total out-of-pocket treatment costs, followed by safety risks. While patients and physicians generally shared similar treatment preferences, patients placed a higher RAI on total out-of-pocket costs than did physicians (50.4% vs. 39.4%). Conversely, patients assigned lower RAI values to the risks of nasopharyngitis and pruritus (15.2% vs. 17.9% and 11.7% vs. 16.2%, respectively). The RAI for the number of tablets taken daily was higher than that for treatment duration among patients (11.6% vs. 0.2%), but nearly equal among physicians.

LIMITATIONS

The study had potential non-response bias, physicians not being actual care providers for surveyed patients, a small sample size, reliance on predefined DCE attributes, and limited participant diversity from online panels.

CONCLUSIONS

This study highlights the importance of patient-centered care in HCV treatment and the need to raise awareness of the public subsidy for hepatitis, and to ensure an effective access scheme for the patients. Simplifying regimens like once-daily pills and minimal monitoring may enhance treatment convenience. Improved patient-physician communication supports optimized strategies, aiding Japan's goal of HCV elimination by 2030.

TELEnutrition and KIdNey hEalth Study: protocol for a randomised controlled trial comparing the effect of digital health to standard care on serum phoSphate control in patients on dIalysiS (TeleKinesis Study)

INTRODUCTION

Diet and nutrition play a vital role in all stages of chronic kidney disease (CKD) prevention, treatment and management. In particular, dietary interventions are essential to manage hyperphosphataemia, a common metabolic complication in CKD consistently associated with an increased risk of cardiovascular disease and all-cause morbidity and mortality. Unfortunately, dietary management of any kind in this cohort of patients also comes with the added challenge of limited and variable access to renal dietitians, logistical difficulties and multiple medical appointments. Given the complexity of managing diet in patients on dialysis, there is a need for novel interventions that not only help patients navigate daily challenges but could also be integrated into clinical practice to support the work of dietitians. We are testing if the use of digital health (via a new, specifically designed smartphone App) plus standard care compared to standard care alone is a feasible and effective method of delivering nutritional advice to patients with elevated phosphate levels undertaking dialysis.

METHODS AND ANALYSIS

This is a multicentre codesigned randomised controlled trial (RCT) that will recruit individuals aged 18 years or over on maintenance dialysis for a minimum of 3 months who have a serum phosphate level of ≥1.6 mmol/L. Participants will be recruited from 23 different dialysis sites across Australia. They will be block randomised into two groups in a 1:1 ratio that will either be the intervention group (receive the TeleKinesis App for 3 months in addition to standard care) or the control group (standard care alone). The primary outcome of the study is to assess the effect of this intervention on the change in patients' serum phosphate levels. The RCT will assess the effectiveness of the programme by comparing serum phosphate at baseline, 3 months and follow-up at 6 months. A total recruitment target of n=180 participants is expected.

ETHICS AND DISSEMINATION

Ethics approval was received from the Sir Charles Gairdner and Osborne Park Health Care Group Human Research Ethics Committee on 5 December 2022 (reference RGS0000005559). Informed consent will be given by participants once they have read and signed the patient information and consent form. The results are expected to be published in scientific journals and presented at clinical research conferences and to the consumers who have taken part in the trial. This is protocol 1.0 dated 10 November 2024.

The Effect of Intervention Preference Matching on Outcomes and Engagement in a Post-cessation Weight Management Trial

PurposeThis study examined the effect of intervention treatment preference in a post-smoking cessation weight management trial.Design & SettingParticipants were randomized to a weight management intervention (Stability, Loss, or Bibliotherapy); all participants received a standard smoking cessation program. Adults aged 18+ were recruited from Memphis, TN, and nationally.ParticipantsIndividuals were eligible if they had a BMI of 22 kg/m2 or greater.MeasuresParticipants were asked about their preferred weight intervention at screening. Weight change and self-reported point-prevalence abstinence were assessed (Month 12). Participants rated perceived effectiveness, difficulty (screening, Month 2), and intervention satisfaction (Month 12).AnalysisWe examined the effect of intervention preference match on 12-month weight change, smoking cessation, perceived effectiveness, difficulty, and satisfaction.ResultsParticipants (n = 305) were majority female (68%); white (52%); and had overweight/obesity (87%). At screening, most participants perceived the Loss intervention as most effective; at Month 2, Stability was perceived as most effective. The Stability intervention was perceived as easiest at screening and Month 2. Those who were matched to their treatment preference had greater 12-month weight loss, but similar rates of smoking cessation.ConclusionsParticipants who were matched to their preference were more successful in preventing post-cessation weight gain, compared to those who were not matched. Future research should systematically test intervention preference effects with the aim of precision health.

Pragmatic Indicated Prevention and Early Intervention for Disordered Eating: A Randomized Controlled Trial of Media Smart Targeted Internet Program in Youth

OBJECTIVE

We evaluated 3 new features of Media Smart Targeted (MST), an 8-module Internet, self-guided, indicated prevention and early intervention for disordered eating (DE): a broader audience, optimal rate of program delivery, and impact on social media (SM) behaviors.

METHOD

Participants (N = 555, aged 13-25 years, of any gender, from Australia and New Zealand) were randomized to: MST-Flexible (MST-F: user accesses modules at own rate, n = 184); MST-Standard (MST-S: weekly module release, n = 187); and control (body image tips, n = 184). Primary (Eating Disorder Examination-Questionnaire [EDE-Q] Global and DE diagnostic status), secondary (DE risk factors) and tertiary (SM) outcome measures were completed at baseline and at post-program, 6-month, and 12-month follow-up.

RESULTS

A total of 52.2% of participants randomized to MST-F or MST-S accessed their intervention. Modified intent-to-treat analyses (n = 378) included these participants (MST-F = 109; MST-S = 84) and all controls (n = 184) showed MST-F participants were more likely to complete each module and full program than MST-S participants. More favorable outcomes for EDE-Q Global were reported in the MST-F condition than control. MST-F and MST-S participants with baseline DE were 94% and 92% respectively less likely than controls to meet DE criteria at any point from post program onward (n = 36). Compared to controls, participants in the MST-F condition experienced significant improvements regarding regular eating, clinical impairment, internalization, and SM behaviors, including reduced appearance comparisons, following of appearance-based influencers, use of TikTok, and fewer SM accounts.

CONCLUSION

Although self-guided Internet interventions have lower completion rates and more modest effects than face-to-face indicated prevention programs, MST-F can be delivered at scale, with low cost and greater flexibility in target audience, to achieve meaningful reductions in DE risk, symptoms, and SM behaviors.

Integrating a randomized controlled trial with a parallel observational cohort study in cervical spine surgery insights from the foraminotomy ACDF cost-effectiveness trial (FACET)

BACKGROUND CONTEXT

In most randomized controlled trials (RCT), data is primarily and often only available for individuals who have agreed to be randomized, with little, if any, consideration for those who elected not to participate.

PURPOSE

This study evaluated the value of including a concurrent observational cohort of patients who declined randomization in the Foraminotomy ACDF Cost-Effectiveness Trial (FACET-RCT) but still underwent anterior or posterior cervical surgery. The goal was to determine if the FACET-RCT results could be generalized by comparing baseline characteristics and clinical outcomes between the randomized trial and observational cohort.

STUDY DESIGN/SETTING

A nationwide RCT with a parallel observational cohort recruiting patients from routine care.

PATIENT SAMPLE

Between January 2016 and May 2020, 389 patients with cervical radiculopathy were screened, and 358 were eligible. Of these, 265 (74%) were randomized in the FACET-RCT for either posterior or anterior cervical surgery, while 80 (22%) opted out of randomization and were followed in an observational cohort. Only 13 (4%) patients declined participation in both FACET-RCT and cohort.

OUTCOME MEASURES

Demographic data was collected, and primary outcomes included treatment success, evaluated using the Odom criteria as well as reduction in arm pain, assessed with a Visual Analogue Scale (VAS) at 6 weeks, and every 6 months up to 2 years postsurgery. Secondary outcomes included VAS for neck pain, neck disability, work ability, quality of life, treatment satisfaction, and need for revision surgeries.

METHODS

Baseline characteristics were compared between the FACET-RCT and cohort using logistic regression. Primary and secondary outcomes were analyzed for differences between study designs using mixed-model analyses adjusted for confounders. The primary noninferiority endpoint of the FACET-RCT was evaluated in both the cohort and combined data from both cohort and FACET-RCT at 2 years of follow-up.

RESULTS

Patients in the cohort were slightly younger than those in the FACET-RCT (mean age of 48.4 versus 51.2 years; mean difference [MD], -2.5; 95% confidence interval [CI], -4.8 to -0.2; p=.04). In sub-analyses stratified by surgical approach (anterior vs. posterior surgery), fewer patients in the observational cohort who underwent posterior surgery reported severe neck pain at baseline compared to their counterparts in the FACET-RCT (OR, 0.38; 95% CI: 0.14 to 0.92; p=.04). No other significant baseline differences were found. No significant differences in treatment success (OR, 1.3; 95% CI: 0.3 to 6.0; p=.75) and arm pain reduction (MD, -3.9; 95% CI: -9.2 to 1.5; p=.16) were observed between study designs. The primary noninferiority endpoint was achieved in the combined data from both the cohort and FACET-RCT, with a narrower CI compared to the FACET-RCT alone, indicating a more robust result. Secondary outcomes were comparable between groups.

CONCLUSIONS

Randomization did not influence clinical outcomes for cervical surgery patients. Combining RCT with the observational cohort increased statistical power, external validity and robustness. Our findings support the value of observational methods as a complement to RCTs, especially when a large number of patients refuse RCT participation and high dropout and crossover rates are expected.

Understanding change from the patient perspective in a transdiagnostic Internet-based intervention for emotional disorders: a qualitative content analysis

Qualitative investigations that openly explore changes and facilitators of changes from the patient's perspective might offer valuable insights on impacts of therapy and helpful and hindering aspects. Our aim for this study was to explore the perspective of patients on a transdiagnostic Internet-based intervention to understand (1) which changes (positive as well as negative effects) responders and non-responders experienced, and (2) which aspects of the intervention they found helpful or hindering in facilitating those changes. We interviewed 21 patients that showed response or non-response to treatment using the Change Interview Schedule following a 10-week Internet-based intervention based on the Unified Protocol. Interviews were analyzed using qualitative content analysis. Both responders and non-responders reported positive changes, with few negative changes mentioned. Across both groups, increased positive affect was reported most frequently (81%). Both groups reported helpful factors, with guidance mentioned most frequently across both responders and non-responders (85.7%). Mainly, aspects of the specific framework were perceived as hindering (e.g. lack of personalization) (66.7%). Overall, patients reported mostly positive impacts, even if they did not respond to treatment. Results highlighted that what patients find helpful or hindering is individual.

Neuromodulation perception by the general public

The development of neurotechnologies offers exciting opportunities for novel brain interventions. Public perception plays a crucial role in determining the success and acceptance of these interventions. This study aimed to understand the general non-expert population's representation of neuromodulation and their preferences for common methods such as pharmaceutical drugs, brain implants, ultrasound, magnetic, and electrical stimulations. We conducted a comprehensive online survey with 784 participants to assess their perception of neuromodulation before and after providing information. We also asked the participants to rank their preferences for different neuromodulation techniques after being provided with information. Statistical analyses included inferential non-linear models and free-text data mining. Our findings revealed that overall, neuromodulation was positively perceived by the participants. Furthermore, providing information resulted in a significant improvement in participants' perception of neuromodulation. Ultrasound stimulation emerged as the most preferred treatment choice, while pharmaceutical drugs were considered a middle-choice option and brain implants ranked last due to safety concerns. Healthcare providers could benefit from enhancing patient education and awareness to promote informed decision-making and improve treatment adherence. Additionally, stakeholders have to address the existing distrust surrounding pharmaceutical drugs and prioritize the development and promotion of safe, non-invasive neuromodulation treatments.

The impact of patient choice on uptake, adherence, and outcomes across depression, anxiety, and eating disorders: a systematic review and meta-analysis

Growing evidence highlights the critical role of patient choice of treatment, with significant benefits for outcomes found in some studies. While four meta-analyses have previously examined the association between treatment choice and outcomes in mental health, robust conclusions have been limited by the inclusion of studies with biased preference trial designs. The current systematic review included 30 studies across three common and frequently comorbid mental health disorders (depression N = 23; anxiety, N = 5; eating disorders, N = 2) including 7055 participants (Mage 42.5 years, SD 11.7; 69.5% female). Treatment choice most often occurred between psychotherapy and antidepressant medication (43.3%), followed by choice between two different forms of psychotherapy, or elements within psychotherapy (36.7%). There were insufficient studies with stringent designs to conduct meta-analyses for anxiety or eating disorders as outcomes, or for treatment uptake. Treatment choice significantly improved outcomes for depression (d = 0.17, n = 18) and decreased therapy dropout, both in a combined sample targeting depression (n = 12), anxiety (n = 4) and eating disorders (n = 1; OR = 1.46, 95% CI: 1.17, 1.83), and in a smaller sample of the depression studies alone (OR = 1.65, 95% CI: 1.05, 2.59). All studies evaluated the impact of adults making treatment choices with none examining the effect of choice in adolescents. Clear directions in future research are indicated, in terms of designing studies that can adequately test the treatment choice and outcome association in anxiety and eating disorder treatment, and in youth.

Low-Income Participants' Preference Between Financial Incentives for Behavioral Goals vs Weight Loss Targets and Associations With Behavioral Goal Adherence

PURPOSE

Examine associations between whether participants' were matched to their preferred financial incentive design and behavioral goal adherence in a weight management intervention.

DESIGN

Secondary quantitative analysis incorporating qualitative survey data.

SETTING

Primary care clinics in socioeconomically disadvantaged communities in New York City and Los Angeles.

SUBJECTS

668 participants (mean age 47.7 years, 81.0% female, 72.6% Hispanic) with obesity were enrolled in the Financial Incentives foR Weight Reduction (FIReWoRk) intervention.

MEASURES

We explored qualitatively participant's reasons for hypothetically choosing a behavioral goal-directed vs a weight loss outcome-based financial incentive program. Additionally, behavioral adherence to different goals was collected at the 6-month timepoint, categorized by match to preferred financial incentive design.

ANALYSIS

Logistic regression was used to examine if participants with certain demographic and higher psychosocial factors were more likely to choose goal-directed over outcome-based incentives. Additionally, logistic regression was used to test for associations between preference and behavioral adherence, using incentive type as an interaction term.

RESULTS

60.2% of participants preferred the goal-directed incentive, with the majority stating that it was more structured. Married participants were more likely to prefer goal-directed incentives (OR = 1.57, CI = 1.06-2.33, P = .025). Moderation analysis revealed that participants who preferred goal-directed and were matched to goal-directed had greater rates of behavioral adherence for program attendance and self-weighing, but not dietary tracking and physical activity tracking, compared to those who preferred outcome-based and were matched to outcome-based.

CONCLUSION

Receiving one's preferred incentive design may not play a strong role in behavioral goal adherence during financially incentivized weight loss interventions.

Preferences of people with diabetes for diabetes care in Germany: a discrete choice experiment

OBJECTIVES

The objective of this study is to elicit health care preferences of people with diabetes and identify classes of people with different preferences.

METHODS

A discrete choice experiment was conducted among people with diabetes in Germany comprising attributes of role division in daily diabetes care planning, type of lifestyle education, support for correct medication intake, consultation frequency, emotional support, and time spent on self-management. A conditional logit model and a latent class model were used to elicit preferences toward diabetes care and analyze preference heterogeneity.

RESULTS

A total of 76 people with diabetes, recruited in two specialized diabetes care centers in Germany (mean age 51.9 years, 37.3% women, 49.1% type 2 diabetes mellitus, 50.9% type 1 diabetes mellitus), completed the discrete choice experiment. The most important attributes were consultation frequency, division in daily diabetes care planning, and correct medication intake. The latent class model detected preference heterogeneity by identifying two latent classes which differ mainly with respect to lifestyle education and medication intake.

CONCLUSION

While the majority of people with diabetes showed preferences in line with current health care provision in Germany, a relevant subgroup wished to strengthen lifestyle education and medication intake support with an aid or website.

Mobile solution and chronic diseases: development and implementation of a mobile application and digital platform for collecting, analyzing data, monitoring and managing health care

BACKGROUND

Technological advances based on mobile health (mHealth), the field of digital health (eHealth) aimed at managing health services and care and their concomitant transformations, have become increasingly important in the 21st century. In this context, care for individuals diagnosed with Chronic Non-Communicable Diseases (CNCDs) deserves to be highlighted. The aim of this study is to present the creation, development and implementation of the Telehealth Center of the Federal University of Viçosa (NUTELES - UFV), for the monitoring and management of health care for individuals with Arterial Hypertension (AH) and/or Diabetes Mellitus (DM).

METHODS

This study, carried out in 2022 and 2023, involved 374 patients diagnosed with AH and/or DM in the health micro-region of Viçosa/MG, Brazil, comprising nine municipalities. The research aims to describe the creation, development and implementation of a software (NutelesApp) for the collection, storage, management and analysis of epidemiological research in public health, focusing specifically, on the monitoring and management of health care for individuals with AH and/or DM monitored by Primary Health Care (PHC). The parameters collected and analyzed were obtained through a questionnaire applied to patients, consisting of 70 questions, subdivided into 12 classes of questions. The epidemiological survey data was collected using mobile devices and analyzed using computer techniques based on statistical analysis. Once the field teams had completed their work, the files were transferred to servers for general analysis processing, using estimates of means, prevalence and respective standard errors, calculated using the Statistical Package for Social Science (SPSS) program, which takes into account the planning variables and includes the basic weights resulting from the sampling process. This study was approved by the Human Research Ethics Committee and registered, prior to recruitment, by the Brazilian Registry of Clinical Trials (ReBEC), ID: RBR-45hqzmf (Last approval date: 11/30/2022).

RESULTS

The information obtained through data collection with subsequent exploratory analysis of epidemiological data using the NutelesApp software suggests that mobile applications intended for the purpose of monitoring and managing healthcare for people with AH and/or DM should address the variables necessary to support a process of understanding the health conditions and/or disease of the individual as a whole and provide short- and long-term learning. Regarding the results of the survey using the software, the variables of 374 people were analyzed. Majority are female (73.2%) and white (43.5%). Most patients are elderly (average 64 years), with blood pressure levels within the normal range for this population, BMI indicates overweight, AC increased risk for cardiovascular events and CC within the recommendation value. All biochemical parameters analyzed were above normal limits.

CONCLUSIONS

The description of the creation and development of the software includes practical examples of its implementation, the results collected and its applicability in real scenarios, presenting determining criteria that can provide assertive and timely interventions for monitoring and managing the health and/or disease parameters of patients with HA and/or DM. In addition, the beneficial consequences of using this application will extend to health units and their respective management, improving the services provided by PHC and enhancing strategies and actions for health promotion and disease prevention.

Utilizing technology for diet and exercise change in complex chronic conditions across diverse environments (U-DECIDE): feasibility randomised controlled trial

BACKGROUND

Diet and exercise are important components of treatment for complex chronic conditions, however access to allied health support is limited. When available, support is often siloed and fragmented. Digital health incorporating patient choice may help to align health care services with preferences and goals. This study evaluated the implementation of a ubiquitously accessible patient-centred digital health diet and exercise service.

METHODS

U-DECIDE was a single-centre, 26-week randomised controlled trial set in kidney and liver disease clinics in a tertiary hospital in Brisbane, Australia. Participants were adults with a complex chronic condition referred for dietetic consultation with at least one feature of the metabolic syndrome. All participants received a dietary consultation, an activity monitor and usual care. Intervention participants were offered one text message per week and access to additional digital health options (increased text message frequency, nutrition app, exercise app, group-based diet and/or exercise video consultations). The primary outcome of feasibility was determined by safety (study-related serious adverse events: SRSAEs), recruitment (≥ 50% eligible patients), retention (≥ 70%), exposure uptake (≥ 75% of intervention group had greater access to health professional contact than comparator) and video consultation adherence (≥ 80% attendance). Secondary outcomes included process evaluation metrics and clinical outcomes.

RESULTS

Of 67 participants (intervention n = 33, comparator n = 34), 37 (55%) were men, median (IQR) age was 51 (41-58) years. The most chosen digital health options were the nutrition app (n = 29, 88%) and exercise video consultations (n = 26, 79%). Only one participant chose no additional digital health options. The intervention group had no SRSAEs. The study exceeded targets for recruitment (52%), retention (81%) and exposure uptake (94%). Video consultation adherence was 42%. Engagement across digital health options was inconsistent.

CONCLUSIONS

Digital health options incorporating patient choice were feasible and can be offered to people with complex chronic disease as a service model option.

Developing an individualized treatment rule for Veterans with major depressive disorder using electronic health records

Efforts to develop an individualized treatment rule (ITR) to optimize major depressive disorder (MDD) treatment with antidepressant medication (ADM), psychotherapy, or combined ADM-psychotherapy have been hampered by small samples, small predictor sets, and suboptimal analysis methods. Analyses of large administrative databases designed to approximate experiments followed iteratively by pragmatic trials hold promise for resolving these problems. The current report presents a proof-of-concept study using electronic health records (EHR) of n = 43,470 outpatients beginning MDD treatment in Veterans Health Administration Primary Care Mental Health Integration (PC-MHI) clinics, which offer access not only to ADMs but also psychotherapy and combined ADM-psychotherapy. EHR and geospatial databases were used to generate an extensive baseline predictor set (5,865 variables). The outcome was a composite measure of at least one serious negative event (suicide attempt, psychiatric emergency department visit, psychiatric hospitalization, suicide death) over the next 12 months. Best-practices methods were used to adjust for nonrandom treatment assignment and to estimate a preliminary ITR in a 70% training sample and to evaluate the ITR in the 30% test sample. Statistically significant aggregate variation was found in overall probability of the outcome related to baseline predictors (AU-ROC = 0.68, S.E. = 0.01), with test sample outcome prevalence of 32.6% among the 5% of patients having highest predicted risk compared to 7.1% in the remainder of the test sample. The ITR found that psychotherapy-only was the optimal treatment for 56.0% of patients (roughly 20% lower risk of the outcome than if receiving one of the other treatments) and that treatment type was unrelated to outcome risk among other patients. Change in aggregate treatment costs of implementing this ITR would be negligible, as 16.1% fewer patients would be prescribed ADMs and 2.9% more would receive psychotherapy. A pragmatic trial would be needed to confirm the accuracy of the ITR.

Optimizing military mental health and stress resilience training through the lens of trainee preferences: A conjoint analysis approach

Effective mental health and stress resilience (MHSR) training is essential in military populations given their exposure to operational stressors. The scarcity of empirical evidence supporting the benefits of these programs emphasizes the need for research dedicated to program optimization. This paper aims to identify the relative importance of MHSR training attributes preferred by military members. Conjoint analysis (CA), an experimental method used to prioritize end-user preferences for product feature development, was conducted using an online survey with 567 Canadian Armed Forces (CAF) personnel. Participants made a series of choices between hypothetical MHSR training options that were systematically varied across seven training attributes. Each training attribute consisted of 3-4 variations in the nature of the attribute or its intensity. Participants also completed questions on health beliefs, mental health and previous MHSR training experiences, and demographics, to assess whether preferences varied by individual characteristics. CA demonstrated that instructor type, leadership buy-in, degree of skills practice, and content relevance/applicability were attributes of highest and relatively equal importance. This was followed by degree of accessible supplemental content. Lowest importance was placed on degree of behavioral nudging and demographic similarity between the trainee and trainer. Sociodemographic factors were not associated with MHSR training preferences. Programs that incorporate expert-led instruction, demonstrate leadership buy-in, embed practical applications within simulated stress environments, and provide a digitally-accessible platform to augment training may be well-received among military members. Understanding and accommodating personal preferences when designing MHSR training programs may increase relevance, foster acceptance and trust, and support sustained engagement.

Patient's Preference for Same-Day Discharge or Hospitalization After Bariatric Surgery

PURPOSE

Enhanced Recovery After Bariatric Surgery protocols have proven to be effective in reducing complication rates and length of stay. Guidelines do not include a recommendation on the length of hospital stay whereas same-day discharge is currently widely investigated on safety and feasibility. However, none of these studies takes patient preferences into account. The study aimed to reveal the patient's preference for outpatient surgery (OS) in patients who underwent primary bariatric surgery.

MATERIALS AND METHODS

A single-center preference-based randomized trial was performed between March and December of 2021. Adult patients planned for primary bariatric surgery were able to choose their care pathway, either OS with remote heart and respiratory rate monitoring by a wearable data logger or standard care with at least one-night hospitalization.

RESULTS

Out of the 202 patients, nearly everyone (98.5%) had a preference. Of 199 patients, 99 (49.7%) chose inpatient surgery. Of the 100 with a preference for OS, 23 stayed in the hospital due to medical reasons and 12 patients changed their preference. Based on both initial preference and changed preference, there were no differences between sex, age, body mass index, and co-morbidities such as diabetes mellitus, hypertension, and atrial fibrillation, nor in the use of anticoagulants or type of surgery.

CONCLUSION

Patients seemed to have a strong preference for their stay after a bariatric procedure. The preference is equally divided between outpatient and inpatient surgery and is not influenced by any patient characteristics.

Long-term health outcomes for patients with obstructive sleep apnea: placing the Agency for Healthcare Research and Quality report in context-a multisociety commentary

This multisociety commentary critically examines the Agency for Healthcare Research and Quality (AHRQ) final report and systematic review on long-term health outcomes in obstructive sleep apnea. The AHRQ report was commissioned by the Centers for Medicare & Medicaid Services and particularly focused on the long-term patient-centered outcomes of continuous positive airway pressure, the variability of sleep-disordered breathing metrics, and the validity of these metrics as surrogate outcomes. This commentary raises concerns regarding the AHRQ report conclusions and their potential implications for policy decisions. A major concern expressed in this commentary is that the AHRQ report inadequately acknowledges the benefits of continuous positive airway pressure for several established, long-term clinically important outcomes including excessive sleepiness, motor vehicle accidents, and blood pressure. While acknowledging the limited evidence for the long-term benefits of continuous positive airway pressure treatment, especially cardiovascular outcomes, as summarized by the AHRQ report, this commentary reviews the limitations of recent randomized controlled trials and nonrandomized controlled studies and the challenges of conducting future randomized controlled trials. A research agenda to address these challenges is proposed including study designs that may include both high quality randomized controlled trials and nonrandomized controlled studies. This commentary concludes by highlighting implications for the safety and quality of life for the millions of people living with obstructive sleep apnea if the AHRQ report alone was used by payers to limit coverage for the treatment of obstructive sleep apnea while not considering the totality of available evidence.

Different dosages of vonoprazan for gastroesophageal reflux disease: study protocol for a pragmatic, crossover-cluster, randomized controlled trial with patient preference arms

BACKGROUND

Vonoprazan results in more potent acid suppression for gastroesophageal reflux disease (GERD) than proton pump inhibitors. It has only been approved for treating erosive esophagitis in China, but 30-40% of GERD patients cannot achieve the goal of treatment with vonoprazan 20 mg daily. This study aims to investigate whether vonoprazan could relieve the symptoms of Chinese patients with non-erosive reflux disease (NERD) and whether increased dosage or different times of dosing could increase the response rate of GERD.

METHODS

This study is a pragmatic, open-label, crossover-cluster, randomized controlled trial with patient preference arms. Two thousand eight hundred eighty patients with GERD from 48 hospitals in China will be enrolled. These hospitals will be divided into a compulsory randomization cluster (24 hospitals) and a patient preference cluster (24 hospitals). Patients in the compulsory randomization cluster will be randomized to three regimens according to the crossover-cluster randomization. Patients in the patient preference cluster may choose to receive any regimen if they have a preference; otherwise, patients will be randomly assigned. The three treatment regimens will last 4 weeks, including (1) vonoprazan 20 mg p.o. after breakfast, (2) vonoprazan 20 mg p.o. after dinner, and (3) vonoprazan 20 mg p.o. after breakfast and after dinner. Patients will attend a baseline visit, a 4-week e-diary, a fourth-week visit, and a sixth-month visit online. The primary outcome is the symptom relief rate of all patients after 4-week therapy. Secondary outcomes include the healing rate of EE patients, the severity of symptoms, compliance with the therapy at the fourth-week follow-up visit, recurrent symptoms, and the frequency of self-conscious doctor visits at the sixth-month follow-up visit.

DISCUSSION

This trial will explore the effectiveness of different regimens of vonoprazan that will be implemented with GERD patients in China. The randomization with patient preferences considered and the crossover-cluster component may improve the robustness and extrapolation of study conclusions.

The Montreal model: an integrative biomedical-psychedelic approach to ketamine for severe treatment-resistant depression

Background

Subanesthetic ketamine has accumulated meta-analytic evidence for rapid antidepressant effects in treatment-resistant depression (TRD), resulting in both excitement and debate. Many unanswered questions surround ketamine's mechanisms of action and its integration into real-world psychiatric care, resulting in diverse utilizations that variously resemble electroconvulsive therapy, conventional antidepressants, or serotonergic psychedelics. There is thus an unmet need for clinical approaches to ketamine that are tailored to its unique therapeutic properties.

Methods

This article presents the Montreal model, a comprehensive biopsychosocial approach to ketamine for severe TRD refined over 6 years in public healthcare settings. To contextualize its development, we review the evidence for ketamine as a biomedical and as a psychedelic treatment of depression, emphasizing each perspectives' strengths, weaknesses, and distinct methods of utilization. We then describe the key clinical experiences and research findings that shaped the model's various components, which are presented in detail.

Results

The Montreal model, as implemented in a recent randomized clinical trial, aims to synergistically pair ketamine infusions with conventional and psychedelic biopsychosocial care. Ketamine is broadly conceptualized as a brief intervention that can produce windows of opportunity for enhanced psychiatric care, as well as powerful occasions for psychological growth. The model combines structured psychiatric care and concomitant psychotherapy with six ketamine infusions, administered with psychedelic-inspired nonpharmacological adjuncts including rolling preparative and integrative psychological support.

Discussion

Our integrative model aims to bridge the biomedical-psychedelic divide to offer a feasible, flexible, and standardized approach to ketamine for TRD. Our learnings from developing and implementing this psychedelic-inspired model for severe, real-world patients in two academic hospitals may offer valuable insights for the ongoing roll-out of a range of psychedelic therapies. Further research is needed to assess the Montreal model's effectiveness and hypothesized psychological mechanisms.

Internet-delivered cognitive behavioural therapy for symptoms of PTSD among public safety personnel: Initial outcomes of an open cohort preference trial of transdiagnostic and disorder-specific therapy

Public safety personnel (PSP) face high rates of mental health problems and many barriers to care. Initial outcomes of transdiagnostic internet-delivered cognitive behavioural therapy (ICBT) tailored for PSP are promising, but prior research has not evaluated outcomes of PTSD-specific ICBT among PSP or PSP's preferences for transdiagnostic or PTSD-specific ICBT. The current paper presents the initial outcomes (N = 150) of a mixed-methods observational study designed to (a) investigate preferences for transdiagnostic or PTSD-specific ICBT among PSP with elevated symptoms of PTSD and/or a primary concern with PTSD symptoms and (b) explore potential differences in client engagement, satisfaction, and symptom changes between the two forms of ICBT. PSP completed questionnaires before and after their preferred ICBT program. Mixed-methods analyses included generalized estimating equations, descriptive statistics, and inductive conventional qualitative content analysis. More clients (n = 85; 57 %) selected transdiagnostic ICBT than PTSD-specific ICBT (n = 65; 43 %), but the difference in the number of clients who selected each course was not statistically significant. Clients in both ICBT programs reported similar and favorable treatment satisfaction (e.g., 98 % would recommend the course to a friend), treatment engagement (i.e., 69 % accessed at least four of the five lessons), and pre-post improvement in symptoms (e.g., Hedges' g = 0.81 for reduction in PTSD symptom). Transdiagnostic ICBT resulted in greater reductions in symptoms of panic disorder than PTSD-specific ICBT. Qualitative analyses showed similarities across the ICBT programs in client feedback. The current study provides further evidence supporting the use and outcomes of ICBT for PSP in both transdiagnostic and disorder-specific formats. Implications for the literatures on PSP mental health and ICBT, as well as practical recommendations, are discussed.

Strategies to Assess the Effect of Continuous Positive Airway Pressure on Long-Term Clinically Important Outcomes among Patients with Symptomatic Obstructive Sleep Apnea: An Official American Thoracic Society Workshop Report

Continuous positive airway pressure (CPAP) is the first-line treatment for obstructive sleep apnea (OSA). Although CPAP improves symptoms (e.g., daytime sleepiness), there is a lack of high-quality evidence that CPAP prevents many long-term outcomes, including cognitive impairment, myocardial infarction, and stroke. Observational studies suggest that patients with symptoms may be particularly likely to experience these preventive benefits with CPAP, but ethical and practical concerns limited the participation of such patients in prior long-term randomized trials. As a result, there is uncertainty about the full benefits of CPAP, and resolving this uncertainty is a key priority for the field. This workshop assembled clinicians, researchers, ethicists, and patients to identify strategies to understand the causal effects of CPAP on long-term clinically important outcomes among patients with symptomatic OSA. Quasi-experimental designs can provide valuable information and are less time and resource intensive than trials. Under specific conditions and assumptions, quasi-experimental studies may be able to provide causal estimates of CPAP's effectiveness from generalizable observational cohorts. However, randomized trials represent the most reliable approach to understanding the causal effects of CPAP among patients with symptoms. Randomized trials of CPAP can ethically include patients with symptomatic OSA, as long as there is outcome-specific equipoise, adequate informed consent, and a plan to maximize safety while minimizing harm (e.g., monitoring for pathologic sleepiness). Furthermore, multiple strategies exist to ensure the generalizability and practicality of future randomized trials of CPAP. These strategies include reducing the burden of trial procedures, improving patient-centeredness, and engaging historically excluded and underserved populations.

Treatment preference changes after exposure to treatment in adults with chronic low back pain

BACKGROUND

Patients' pretreatment preferences can influence outcomes of nonpharmacologic treatments for musculoskeletal pain. Less is known about how patients' treatment preferences change following exposure to treatment.

OBJECTIVE

To examine the effect of exposure to treatment and change in disability and pain on treatment preference ratings of two exercise-based treatments for people with chronic low back pain (LBP).

DESIGN

Secondary analysis of a subsample of participants from a randomized clinical trial.

SETTING

Academic research setting.

PARTICIPANTS

Individuals with chronic LBP (n = 83).

INTERVENTIONS

6 weekly sessions of motor skill training (MST) or strength and flexibility exercise (SFE).

MAIN OUTCOME MEASURES

Prior to treatment, participants completed a treatment preference assessment measure (TPA) describing MST and SFE. Participants rated four attributes (effectiveness, acceptability/logicality, suitability/appropriateness, convenience) of each treatment on a 5-point Likert scale (0-4) with higher scores indicating higher ratings. An overall preference rating was calculated as the mean of the attribute ratings. The TPA was administered 12 months post treatment to reassess participants' ratings of the treatment they received.

RESULTS

Participants who received MST rated their preference for MST higher 12 months post treatment and participants who received SFE rated their preference for SFE lower. Smaller improvements (to worsening) in pain were associated with a reduction in preference ratings in the SFE group, whereas the MST group generally increased their ratings regardless of pain. Changes in disability were not related to changes in preference ratings.

CONCLUSIONS

Participants changed their preference ratings of two exercise-based treatments for LBP after exposure to the treatment. Participants who received the less familiar MST viewed this treatment more favorably 12 months post treatment, and this change was less contingent on changes in disability/pain than for participants in the SFE group. Assessing preference ratings at various times during treatment is crucial to understand a person's preference for and perceptions of a treatment.

The impact of treatment preferences: A narrative review

Attending to treatment preferences is an element of person-centred care, reported as beneficial in improving treatment adherence, satisfaction, and outcome, in practice. The results of preference trials were inconsistent in supporting these benefits in intervention evaluation research. Informed by the conceptualisation of treatment preferences positing their indirect impact on outcomes, this narrative review aimed to summarise the evidence on the effects of preferences on enrolment; withdrawal or attrition; engagement, enactment, and satisfaction with treatment; and outcomes. The search yielded 72 studies (57 primary trials and 15 reviews). The results of vote counting indicated that (1) offering participants the opportunity to choose treatment enhances enrolment (reported in 87.5% of studies), and (2) providing treatments that match participants' preferences reduces attrition (48%); enhances engagement (67%), enactment (50%) and satisfaction with (43%) treatment; and improves outcomes (35%). The results are attributed to conceptual and methodological issues including less-than-optimal assessment of treatment preferences, which contributes to ill-identified preferences, accounting for withdrawal, low enactment, and limited satisfaction with treatment. These treatment processes, in turn, mediate the impact of treatment preferences on outcomes. It is important to refine and standardise the methods for assessing preferences and to examine their indirect impact (mediated by treatment processes) on outcomes in future preference trials to validly identify their benefits.

Women want male partner engagement in antenatal care services: A qualitative study of pregnant women from rural South Africa

INTRODUCTION

Evidence strongly shows that a supportive, involved male partner facilitates maternal HIV testing during pregnancy, increases maternal antiretroviral (ART) adherence and increases HIV-free infant survival. Partner engagement in antenatal care (ANC) is influential; however, the most effective strategy to engage male partners is currently unknown. Engaging pregnant women to understand whether male partner involvement is welcome in ANC, what this involvement entails and how best to invite their partner is an important first step in determining how best to engage male partners.

METHODS

We interviewed 36 pregnant women receiving ANC services at a district hospital in rural Mpumalanga, South Africa to assess the strengths and weaknesses of their current relationship, the type of partner support they receive, whether they would like their male partner to be involved in their ANC, and how best to invite their male partner to their appointments. We conducted a thematic analysis of the qualitative interviews using MAXQDA software.

RESULTS

Financial, emotional, and physical support were noted as important aspects of support currently provided by male partners, with most pregnant women wanting their partners to engage in ANC services during pregnancy. Preferred engagement strategies included participation in couple-based HIV testing and counseling, regular ANC appointment attendance, and delivery room presence. Women who reported a positive relationship with her partner were more likely to prefer inviting their partner without health facility assistance, while those who reported challenges in their relationship preferred assistance through a letter or community health worker. Pregnant women perceived regular business hours (due to their partner being employed and unable to take off work) and having a partner involved in multiple relationships as barriers in getting their partner to attend ANC services.

DISCUSSION

Rural South African women, even those in unsatisfactory relationships want their male partners to attend their ANC visits and birth. To make this possible, health facilities will have to tailor male partner engagement outreach strategies to the preferences and needs of the pregnant woman.

A scoping review on two-stage randomized preference trial in the field of mental health and addiction

BACKGROUND

Randomized Controlled Trial is the most rigorous study design to test the efficacy and effectiveness of an intervention. Patient preference may negatively affect patient performance and decrease the generalizability of a trial to clinical population. Patient preference trial have particular implications in the field of mental health and addiction since mental health interventions are generally complex, blinding of intervention is often difficult or impossible, patients may have strong preference, and outcome measures are often subjective patient self-report which may be greatly influenced if patient's preference did not match with the intervention received.

METHODS

In this review, we have surveyed the application of two-stage randomized preference trial with focus on studies in the field of mental health and addiction. The study selection followed the guideline provided by Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews.

RESULTS

Six two-stage randomized preference trials (ten publications) have been identified in the field of mental health field and addiction. In these trials, the pooled dropout rates were 18.3% for the preference arm, and 28.7% for the random arm, with a pooled RR of 0.70 (95% CI, 0.56-0.88; P = 0.010) indicating lower risk of dropout in the preference arm. The standardized preference effects varied widely from 0.07 to 0.57, and could be as large as the treatment effect in some of the trials.

CONCLUSION

This scoping review has shown that two-stage randomized preference trials are not as popular as expected in mental health research. The results indicated that two-stage randomized preference trials in mental health would be beneficial in retaining patients to expand the generalizability of the trial.

Free choice of treatment content, support on demand and supervision in internet-delivered CBT for adults with depression: A randomized factorial design trial

Even if much is known regarding the effects of internet-delivered cognitive behaviour therapy (ICBT) for depression there are several topics that have not been studied. In this factorial design trial with 197 participants we investigated if clients in ICBT could select treatment modules themselves based on a selection of 15 tailored treatment modules developed for use in ICBT for depression. We contrasted this against clinician-tailored module selection. We also investigated if support on demand (initiated by the client) could work as well as scheduled support. Finally, we tested if clients that were mentioned in supervision would improve more than clients not mentioned (with the exception of acute cases). The treatment period lasted for 10 weeks, and we measured effects at post-treatment and two-year follow-up. Measures of depression and secondary outcomes were collected at pre-treatment, post-treatment and two-year follow-up. Overall, within-group effects were large across conditions (e.g., d = 1.73 on the BDI-II). We also found a small but significant difference in favour of self-tailored treatment over clinician-tailored (d = 0.26). Within-group effects for the secondary measures were all moderate to large including a test of knowledge about CBT. The other two contrasts "support on demand" and "supervision" yielded mostly non-significant differences, with the exception of a larger dropout rate in the support on demand condition. There were few negative effects (2.2%). Effects were largely maintained at a two-year follow-up. We conclude that clients can choose treatment modules and that support on demand may work. The role of supervision is not yet clear as advice can be transferred across clients.

Patient Preferences for Treatment of Bacillus Calmette-Guérin-unresponsive Non-muscle-invasive Bladder Cancer: A Cross-country Choice Experiment

Background

Patients with non-muscle-invasive bladder cancer (NMIBC) that is unresponsive to bacillus Calmette-Guérin (BCG) immunotherapy face a difficult choice. Immediate radical cystectomy (RC) is effective but might represent overtreatment. Continuing bladder preservation with medical therapy is an alternative, but it risks progression to muscle-invasive bladder cancer (MIBC) and a reduction in survival.

Objective

To understand the trade-offs patients are willing to make in selecting treatments for BCG-unresponsive NMIBC.

Design setting and participants

Adults with NMIBC from the UK, France, Germany, and Canada who reported current receipt of BCG, disease unresponsive to BCG, or receipt of RC in the previous 12 mo after failure of BCG were recruited to participate in an online choice experiment. Patients were asked to make repeated choices between two hypothetical medical treatments and the option to undergo immediate RC. The medical treatments required trade-offs between the time to RC, the mode and frequency of administration, the risk of experiencing serious side effects, and the risk of disease progression.

Outcome measurements and statistical analysis

Error component logit models were used to calculate relative attribute importance (RAI) scores as the maximum percentage contribution to a preference and acceptable benefit-risk trade-offs.

Results and limitations

Most of the 107 participants (average age 63 yr) never selected RC (89%) as their preferred option in the choice experiment. Preferences were most affected by time to RC (RAI 55%), followed by risk of progressing to MIBC (RAI 25%), medication administration (RAI 12%), and the risk of serious side effects (RAI 8%). To increase the time to RC from 1 yr to 6 yr, patients accepted a 43.8% increase in the risk of progression and a 66.1% increase in the risk of serious side effects.

Conclusions

Patients with BCG-treated NMIBC valued bladder-sparing treatments and were willing to make substantial benefit-risk trade-offs to delay RC.

Patient summary

Adults with bladder cancer not invading the bladder muscle completed an online experiment in which they chose between hypothetical medications and bladder removal. The results show that patients would be willing to accept different risks associated with medications to delay bladder removal. Patients considered disease progression the most important risk of medicinal treatment.

Hypnotic Medications as an Adjunct Treatment to Cognitive Behavioral Therapy for Insomnia

Cognitive behavioral therapy for insomnia (CBT-I) is the universally recommended treatment of choice for insomnia disorder based on its safety and posttreatment durability of benefit. However, CBT-I does not help all patients achieve remission. The second most evidence-based treatment, hypnotic pharmacotherapy (PCT), does not resolve perpetuating factors of insomnia, resulting in potential waning of benefit and dependence. This article presents a rationale that supports consideration of hypnotic augmentation of CBT-I (COMB), along with a review of select randomized controlled trials relevant to clinical decision-making.

Development of a Patient Decision Aid for Rectal Cancer Patients with Clinical Complete Response after Neo-Adjuvant Treatment

Surgery is the primary component of curative treatment for patients with rectal cancer. However, patients with a clinical complete response (cCR) after neo-adjuvant treatment may avoid the morbidity and mortality of radical surgery. An organ-sparing strategy could be an oncological equivalent alternative. Therefore, shared decision making between the patient and the healthcare professional (HCP) should take place. This can be facilitated by a patient decision aid (PtDA). In this study, we developed a PtDA based on a literature review and the key elements of the Ottawa Decision Support Framework. Additionally, a qualitative study was performed to review and evaluate the PtDA by both HCPs and former rectal cancer patients by a Delphi procedure and semi-structured interviews, respectively. A strong consensus was reached after the first round (I-CVI 0.85-1). Eleven patients were interviewed and most of them indicated that using a PtDA in clinical practice would be of added value in the decision making. Patients indicated that their decisional needs are centered on the impact of side effects on their quality of life and the outcome of the different options. The PtDA was modified taking into account the remarks of patients and HCPs and a second Delphi round was held. The second round again showed a strong consensus (I-CVI 0.87-1).

Cost-effectiveness of urethral bulking polydimethylsiloxane-Urolastic® compared with mid-urethral sling surgery for stress urinary incontinence: A two-arm cohort study

OBJECTIVE

To investigate the cost-effectiveness of urethral bulking polydimethylsiloxane-Urolastic® (PDMS-U) compared with mid-urethral sling (MUS) surgery for stress urinary incontinence (SUI) at 1-year follow-up.

DESIGN

Prospective, two-arm cohort study with 2-year follow-up.

SETTING

International multicentre.

POPULATION

Women with moderate to severe SUI.

MAIN OUTCOME MEASURES

Primary outcome was subjective cure (Patient Global Impression of Improvement).

SECONDARY OUTCOMES

objective cure (negative cough stress test), Urogenital Distress Inventory (UDI-6), complications and re-interventions. Cost-effectiveness outcomes: total costs, quality-adjusted life year (QALY) using IIQ7-scores (Incontinence Impact Questionnaire) and EQ-5D-5L, incremental cost-effectiveness ratio (ICER) and monetary benefit (adjusted for baseline confounders).

RESULTS

In all, 131 PDMS-U and 153 MUS surgery patients were treated. Subjective cure rates for MUS surgery and PDMS-U were, respectively: 101/112 (90%) versus 40/87 (46%), adjusted odds ratio (aOR; for age, body mass index [BMI], severity, type of urinary incontinence and previous SUI procedure) was 4.9. Objective cure rates for MUS surgery and PDMS-U were respectively: 98/109 (90%) versus 58/92 (63%), aOR 5.4. Average total costs for PDMS-U and MUS surgery were €3567 and €6688. ICER for MUS surgery cost €15 598 per IIQ QALY and €37 408 per EQ-5D-5L QALY. With a willingness to pay (WTP) of €25 000, MUS has a 84% chance of being cost-effective using IIQ, whereas PDMS-U has a 99% chance of being cost-effective using EQ-5D-5L.

CONCLUSION

MUS surgery is more cost-effective in realising improved disease-specific quality of life (QoL), while PDMS-U is more cost-effective in realising improved generic QoL.

Exercise and education vs intra-articular saline for knee osteoarthritis: a 1-year follow-up of a randomized trial

OBJECTIVE

To assess the longer-term effect of the Good Life with osteoarthritis in Denmark (GLAD) exercise and education program relative to open-label placebo (OLP) on changes from baseline in core outcomes in individuals with knee osteoarthritis (OA).

METHODS

In this 1-year follow-up of an open-label, randomized trial, patients with symptomatic and radiographically confirmed knee OA were monitored after being randomized to either the 8-week GLAD program or OLP given as 4 intra-articular saline injections over 8 weeks. The primary outcome was the change from baseline in the Knee injury and Osteoarthritis Outcome Score questionnaire (KOOS) pain subscale after 1 year in the intention-to-treat population. Key secondary outcomes were the KOOS function and quality of life subscales, and Patients' Global Assessment of disease impact.

RESULTS

206 adults were randomly assigned: 102 to GLAD and 104 to OLP, of which only 137 (63/74 GLAD/OLP) provided data at 1 year. At one year the mean changes in KOOS pain were 8.4 for GLAD and 7.0 for OLP (Difference: 1.5 points; 95% CI -2.6 to 5.5). There were no between-group differences in any of the secondary outcomes.

CONCLUSIONS

In this 1-year follow-up of individuals with knee OA, the 8-week GLAD program and OLP both provided minor longer-term benefits with no group difference. These results require confirmation given the significant loss to follow-up.

Who are likely to benefit from the Good Life with osteoArthritis in Denmark (GLAD) exercise and education program? An effect modifier analysis of a randomised controlled trial

OBJECTIVE

To identify contextual factors that modify the treatment effect of the 'Good Life with osteoArthritis in Denmark' (GLAD) exercise and education programme compared to open-label placebo (OLP) on knee pain in individuals with knee osteoarthritis (OA).

METHODS

Secondary effect modifier analysis of a randomised controlled trial. 206 participants with symptomatic and radiographic knee OA were randomised to either the 8-week GLAD programme (n = 102) or OLP given as 4 intra-articular saline injections over 8 weeks (n = 104). The primary outcome was change from baseline to week 9 in the Knee injury and Osteoarthritis Outcome Score questionnaire (KOOS) pain subscale (range 0 (worst) to 100 (best)). Subgroups were created based on baseline information: BMI, swollen study knee, bilateral radiographic knee OA, sports participation as a young adult, sex, median age, a priori treatment preference, regular use of analgesics (NSAIDs or paracetamol), radiographic disease severity, and presence of constant or intermittent pain.

RESULTS

Participants who reported use of analgesics at baseline seem to benefit from the GLAD programme over OLP (subgroup contrast: 10.3 KOOS pain points (95% CI 3.0 to 17.6)). Participants with constant pain at baseline also seem to benefit from GLAD over OLP (subgroup contrast: 10.0 points (95% CI 2.8 to 17.2)).

CONCLUSIONS

These results imply that patients who take analgesics or report constant knee pain, GLAD seems to yield clinically relevant benefits on knee pain when compared to OLP. The results support a stratified recommendation of GLAD as management of knee OA.

Are Veterans Getting Their Preferred Depression Treatment? A National Observational Study in the Veterans Health Administration

BACKGROUND

Physician responsiveness to patient preferences for depression treatment may improve treatment adherence and clinical outcomes.

OBJECTIVE

To examine associations of patient treatment preferences with types of depression treatment received and treatment adherence among Veterans initiating depression treatment.

DESIGN

Patient self-report surveys at treatment initiation linked to medical records.

SETTING

Veterans Health Administration (VA) clinics nationally, 2018-2020.

PARTICIPANTS

A total of 2582 patients (76.7% male, mean age 48.7 years, 62.3% Non-Hispanic White) MAIN MEASURES: Patient self-reported preferences for medication and psychotherapy on 0-10 self-anchoring visual analog scales (0="completely unwilling"; 10="completely willing"). Treatment receipt and adherence (refilling medications; attending 3+ psychotherapy sessions) over 3 months. Logistic regression models controlled for socio-demographics and geographic variables.

KEY RESULTS

More patients reported strong preferences (10/10) for psychotherapy than medication (51.2% versus 36.7%, McNemar χ²₁=175.3, p<0.001). A total of 32.1% of patients who preferred (7-10/10) medication and 21.8% who preferred psychotherapy did not receive these treatments. Patients who strongly preferred medication were substantially more likely to receive medication than those who had strong negative preferences (odds ratios [OR]=17.5; 95% confidence interval [CI]=12.5-24.5). Compared with patients who had strong negative psychotherapy preferences, those with strong psychotherapy preferences were about twice as likely to receive psychotherapy (OR=1.9; 95% CI=1.0-3.5). Patients who strongly preferred psychotherapy were more likely to adhere to psychotherapy than those with strong negative preferences (OR=3.3; 95% CI=1.4-7.4). Treatment preferences were not associated with medication or combined treatment adherence. Patients in primary care settings had lower odds of receiving (but not adhering to) psychotherapy than patients in specialty mental health settings. Depression severity was not associated with treatment receipt or adherence.

CONCLUSIONS

Mismatches between treatment preferences and treatment type received were common and associated with worse treatment adherence for psychotherapy. Future research could examine ways to decrease mismatch between patient preferences and treatments received and potential effects on patient outcomes.

Self-selection vs Randomized Assignment of Treatment for Appendicitis

Importance

For adults with appendicitis, several randomized clinical trials have demonstrated that antibiotics are an effective alternative to appendectomy. However, it remains unknown how the characteristics of patients in such trials compare with those of patients who select their treatment and whether outcomes differ.

Objective

To compare participants in the Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) randomized clinical trial (RCT) with a parallel cohort study of participants who declined randomization and self-selected treatment.

Design, Setting, and Participants

The CODA trial was conducted in 25 US medical centers. Participants were enrolled between May 3, 2016, and February 5, 2020; all participants were eligible for at least 1 year of follow-up, with all follow-up ending in 2021. The randomized cohort included 1094 adults with appendicitis; the self-selection cohort included patients who declined participation in the randomized group, of whom 253 selected appendectomy and 257 selected antibiotics. In this secondary analysis, characteristics and outcomes in both self-selection and randomized cohorts are described with an exploratory analysis of cohort status and receipt of appendectomy.

Interventions

Appendectomy vs antibiotics.

Main Outcomes and Measures

Characteristics among participants randomized to either appendectomy or antibiotics were compared with those of participants who selected their own treatment.

Results

Clinical characteristics were similar across the self-selection cohort (510 patients; mean age, 35.8 years [95% CI, 34.5-37.1]; 218 female [43%; 95% CI, 39%-47%]) and the randomized group (1094 patients; mean age, 38.2 years [95% CI, 37.4-39.0]; 386 female [35%; 95% CI, 33%-38%]). Compared with the randomized group, those in the self-selection cohort were less often Spanish speaking (n = 99 [19%; 95% CI, 16%-23%] vs n = 336 [31%; 95% CI, 28%-34%]), reported more formal education (some college or more, n = 355 [72%; 95% CI, 68%-76%] vs n = 674 [63%; 95% CI, 60%-65%]), and more often had commercial insurance (n = 259 [53%; 95% CI, 48%-57%] vs n = 486 [45%; 95% CI, 42%-48%]). Most outcomes were similar between the self-selection and randomized cohorts. The number of patients undergoing appendectomy by 30 days was 38 (15.3%; 95% CI, 10.7%-19.7%) among those selecting antibiotics and 155 (19.2%; 95% CI, 15.9%-22.5%) in those who were randomized to antibiotics (difference, 3.9%; 95% CI, -1.7% to 9.5%). Differences in the rate of appendectomy were primarily observed in the non-appendicolith subgroup.

Conclusions and Relevance

This secondary analysis of the CODA RCT found substantially similar outcomes across the randomized and self-selection cohorts, suggesting that the randomized trial results are generalizable to the community at large.

Worry-specific versus self-tailored internet-based treatments for generalized anxiety disorder, with scheduled support or support on demand: A pilot factorial design trial

Studies suggest that internet-delivered cognitive behaviour therapy (ICBT) can be effective when treating generalized anxiety disorder (GAD). This pilot factorial design study examined the effects of two types of ICBT (worry-specific and self-tailored treatment), and two support types (scheduled weekly support and support on demand), on measures of worry, anxiety, and depressive symptoms. Participants (N = 85) were randomized into four treatment groups. Post-treatment measures were completed by 76.5% after eight weeks (n = 65). Intention to treat analysis showed significant improvements, with moderate to large within-group effects on the primary outcome measure, Penn State Worry Questionnaire (Cohen's d = 0.77-1.43). Minor to large effects on the secondary measures were found in all groups (Cohen's d = 0.13-1.66). No significant differences in outcome measures were found between the groups. Receiving scheduled support and self-tailored treatment was rated as more positive than receiving support on demand and the worry-specific program. A limitation is the low number of participants. The pilot results suggest that GAD can be treated with both worry-specific and self-tailored treatments, and that ICBT can be supported both with scheduled and support on demand.

The Potential for Outdoor Nature-Based Interventions in the Treatment and Prevention of Depression

There is growing interest in nature-based interventions (NBI) to improve human health and wellbeing. An important nascent area is exploring the potential of outdoor therapies to treat and prevent common mental health problems like depression. In this conceptual analysis on the nature-depression nexus, we distil some of the main issues for consideration when NBIs for depression are being developed. We argue that understanding the mechanisms, or 'active ingredients' in NBIs is crucial to understand what works and for whom. Successfully identifying modifiable mediating intervention targets will pave the way for interventions with increased efficacy. We highlight a non-exhaustive list of five clinically relevant putative, candidate mechanisms which may underly the beneficial effects of NBIs on depression: stress, rumination, mindfulness, sleep and exercise. We also make the case that when developing NBIs it is important to not neglect young people, explore personalised approaches and focus on both treatment and prevention approaches. To achieve these aims methodologically rigorous programmes of clinical research are needed that include well-powered and controlled experimental designs including randomised controlled trials, qualitative research, longitudinal studies and large prospective cohorts.

Independent Supported Housing for non-homeless individuals with severe mental illness: Comparison of two effectiveness studies using a randomised controlled and an observational study design

BACKGROUND

No randomised controlled study (RCT) on the effectiveness of Independent Supported Housing (ISH) vs. housing as usual (HAU) settings for non-homeless individuals with severe mental illness (SMI) has been conducted to date because of limited feasibility. Alternative designs, such as observational studies, might be suitable for providing adequate evidence if well conducted. To test this hypothesis, this article reports on a prospective, direct comparison of the designs of two parallel studies in this field.

METHODS

A two-centre, parallel-group non-inferiority effectiveness study was conducted at two locations in Switzerland using identical instruments and clinical hypotheses. One centre applied an RCT design and the other an observational study (OS) design with propensity score methods (ClinicalTrials.gov: NCT03815604). The comparability of the two study centres was investigated in terms of participants, procedures, and outcomes. The primary outcome was social inclusion and the secondary outcomes were quality of life and psychiatric symptoms.

RESULTS

The study included 141 participants (RCT: n = 58; OS: n = 83). Within one year, 27% study dropouts occurred (RCT: 34%; OS: 22%). A similar balance of sample characteristics was achieved in the RCT and the OS using propensity score methods (inverse probability of treatment weighting). After one year, ISH was non-inferior to the control condition regarding social inclusion (mean differences [95% CI]) in the RCT (6.28 [-0.08 to 13.35]) and the OS (2.24 [-2.30 to 6.77]) and showed no significant differences in quality of life (RCT: 0.12 [-0.52 to 0.75]; OS: 0.16 [-0.26 to 0.58]) and symptoms (RCT: -0.18 [-0.75 to 0.40]; OS: 0.21 [-0.17 to 0.60]) in both study centres. However, strong and persistent preferences for ISH in the RCT control group reduced participants' willingness to participate. Because of several limitations in the RCT, the results of the RCT and the OS are not comparable.

CONCLUSION

Participants were comparable in both study sites. However, there were significant problems in conducting the RCT because of strong preferences for ISH. The OS with propensity score methods provided results of more stable groups of participants and revealed balanced samples and valid outcome analysis. Our results do not support further investment in RCTs in this field.

The healthcare buffet: preferences in the clinical decision-making process for patients with musculoskeletal pain

The preferences a person has for care are associated with outcomes for patients presenting with musculoskeletal pain conditions. These include preferences for differing levels of involvement in the decision-making process, preferences for the provider attributes, and preferences for particular interventions. In this paper, we discuss these various forms of preference, as well as how they influence clinical care within shared decision-making frameworks. We also present a conceptual framing for how patient preferences can be incorporated in clinical decision-making by orthopedic manual physical therapists. Finally, research implications for interpreting findings from clinical studies are discussed.

Women's experiences of receiving information about and consenting or declining to participate in a randomized controlled trial involving episiotomy in vacuum-assisted delivery: a qualitative study

Background

Information about and invitation to participate in a clinical trial involving an intervention during childbirth may cause fear or worry in pregnant women. The aim of this study was to describe nulliparous women’s experiences of receiving an invitation to participate in a randomized controlled trial (RCT) of lateral episiotomy versus no episiotomy in vacuum-assisted delivery (EVA trial).

Methods

This qualitative study was nested in the ongoing EVA trial. Data were collected through semistructured telephone interviews with 23 women regarding their experiences of the information and invitation to participate in the EVA trial. Interviews were audio-recorded and transcribed verbatim. A qualitative content analysis was used to analyse the interview contents.

Results

Three main experience categories were identified among the participants. “Timing of trial information and understanding” revealed that women preferred to obtain information about the trial early on during pregnancy. “Reasons to consent to or decline participation in the trial” encompassed a variety of reasons for women to consent, such as goodwill for science or personal benefits, or to decline, such as not wanting to be randomized or fear of increased risk of having a vacuum-assisted delivery. “Thoughts evoked regarding childbirth” were diverse, ranging from not being affected at all to having increased anxiety.

Conclusions

The women’s experience of receiving an invitation to participate in an RCT of episiotomy in vacuum-assisted delivery varied widely, from immediately giving consent without further worries to increased anxiety or declining participation. Early and personal information with time for reflection was considered most satisfactory.

Which Trauma Treatment Suits me? Identification of Patients' Treatment Preferences for Posttraumatic Stress Disorder (PTSD)

Several psychotherapy treatments exist for posttraumatic stress disorder. This study examines the treatment preferences of treatment-seeking traumatized adults in Germany and investigates the reasons for their treatment choices. Preferences for prolonged exposure, cognitive behavioral therapy (CBT), eye movement desensitization and reprocessing (EMDR), psychodynamic psychotherapy and stabilization were assessed via an online survey. Reasons for preferences were analyzed by means of thematic coding by two independent rates. 104 traumatized adults completed the survey. Prolonged exposure and CBT were each preferred by nearly 30%, and EMDR and psychodynamic psychotherapy were preferred by nearly 20%. Stabilization was significantly less preferred than all other options, by only 4%. Significantly higher proportions of patients were disinclined to choose EMDR and stabilization. Patients who preferred psychodynamic psychotherapy were significantly older than those who preferred CBT. Reasons underlying preferences included the perceived treatment mechanisms and treatment efficacy. Traumatized patients vary in their treatment preferences. Preference assessments may help clinicians comprehensively address patients' individual needs and thus improve therapy outcomes.

Effect of Prolonged Exposure, intensified Prolonged Exposure and STAIR+Prolonged Exposure in patients with PTSD related to childhood abuse: a randomized controlled trial

Background: It is unclear whether the evidence-based treatments for PTSD are as effective in patients with CA-PTSD. Objective: We aimed to investigate the effectiveness of three variants of prolonged exposure therapy. Method: We recruited adults with CA-PTSD. Participants were randomly assigned to Prolonged Exposure (PE; 16 sessions in 16 weeks), intensified Prolonged Exposure (iPE; 12 sessions in 4 weeks followed by 2 booster sessions) or a phase-based treatment, in which 8 sessions of PE were preceded by 8 sessions of Skills Training in Affective and Interpersonal Regulation (STAIR+PE; 16 sessions in 16 weeks). Assessments took place in week 0 (baseline), week 4, week 8, week 16 (post-treatment) and at a 6-and 12-month follow-up. The primary outcome was clinician-rated PTSD symptom severity. Results: We randomly assigned 149 patients to PE (48), iPE (51) or STAIR+PE (50). All treatments resulted in large improvements in clinician assessed and self-reported PTSD symptoms from baseline to 1-year follow-up (Cohen's d > 1.6), with no significant differences among treatments. iPE led to faster initial symptom reduction than PE for self-report PTSD symptoms (t₁₃₅ = -2.85, p = .005, d = .49) but not clinician-assessed symptoms (t₁₃₅ = -1.65, p = .10) and faster initial symptom reduction than STAIR+PE for self-reported (t₁₃₅ = -4.11, p < .001, d = .71) and clinician-assessed symptoms (t₁₃₅ = -2.77, p = .006, Cohen's d = .48) STAIR+PE did not result in significantly more improvement from baseline to 1-year follow-up on the secondary outcome emotion regulation, interpersonal problems and self-esteem compared to PE and iPE. Dropout rates did not differ significantly between conditions. Conclusions: Variants of exposure therapy are tolerated well and lead to large improvements in patients with CA-PTSD. Intensifying treatment may lead to faster improvement but not to overall better outcomes. The trial is registered at the clinical trial registry, number NCT03194113, https://clinicaltrials.gov/ct2/show/NCT03194113.

Preferences of people with type 2 diabetes for telemedical lifestyle programmes in Germany: protocol of a discrete choice experiment

INTRODUCTION

Telemedical lifestyle programmes for people with type 2 diabetes mellitus (T2DM) provide an opportunity to develop a healthier lifestyle and consequently to improve health outcomes. When implementing new programmes into standard care, considering patients' preferences may increase the success of the participants. This study aims to examine the preferences of people with T2DM with respect to telemedical lifestyle programmes, to analyse whether these preferences predict programme success and to explore the changes that may occur during a telemedical lifestyle intervention.

METHODS AND ANALYSIS

We outline the protocol of the development and assessment of a discrete choice experiment (DCE) to examine patient preferences in a telemedical lifestyle programme with regard to the functions of the online portal, communication, responsibilities, group activities and time requirements. To develop the design of the DCE, we conducted pilot work involving healthcare experts and in particular people with T2DM using cognitive pretesting. The final DCE is being implemented within a randomised controlled trial for investigating whether participation in a telemedical lifestyle intervention programme sustainably improves the HbA1c values in 850 members of a large German statutory health insurance with T2DM. Preferences are being assessed before and after participants complete the programme. The DCE data will be analysed using regression and latent class analyses.

ETHICS AND DISSEMINATION

The DCE study has been approved by the ethics committee of the medical faculty of the Heinrich Heine University Duesseldorf, registration number 2018-242-ProspDEuA, registered on 6 December 2018. The TeLIPro trial is registered at the US National Library of Medicine, registration number NCT03675919, registered on 15 September 2018. We aim to disseminate our results in peer-reviewed journals, at national and international conferences and among interested patient groups and the public.

Musculoskeletal pain stakeholder engagement and partnership development: determining patient-centered research priorities

BACKGROUND

Musculoskeletal (MSK) pain is a global public health problem with increased societal burden. Increased attention has focused toward patient and other stakeholder perspectives when determining future MSK pain research priorities, however infrastructure and capacity building within the community are needed for individuals and organizations to participate in patient-centered outcomes research. The purpose of this manuscript is to describe our collaborative experiences with several MSK pain stakeholders and processes to identify a top priority research topic.

METHODS

Lunch meetings and formalized workshops were used to develop infrastructure for engaging patients and other stakeholders with early capacity building for partners to identify MSK pain research ideas based on their personal experiences. Additional capacity building and engagement through literature searching further prepared partners to contribute informed decisions about MSK pain research topics and subsequent selection of an important research question.

RESULTS

Several key deliverables (e.g., Governance Document, Communication Plan) were developed and completed over the course of this project to provide partnership structure. Other key deliverables included a list of preliminary comparative effectiveness research ideas (n = 8) and selection of shared decision making for MSK pain as the top priority research topic with patient partners identifying pain self-efficacy as an important outcome domain.

CONCLUSIONS

Our patient partners provided the catalyst for identifying shared decision making as a high priority research topic based on a wide spectrum of stakeholder perspectives and unique experiences. Patient partners were primarily identified using a single rehabilitation health system and clinician partners were heavily weighted by physical therapists which may have introduced selection bias.
