Abstract
Economic evaluations are tools for assessing emerging technologies and a complement for decision-making in healthcare systems. However, this topic may not be familiar for doctors and academics, who may be confused when interpreting the results of studies using these tools. Cataract is a disease which has received special attention in healthcare systems due to its high incidence, the great impact that it could have on patients' quality of life, and the fact that it can be definitively solved in almost all cases through cataract surgery. Historically, economic evaluations in cataract surgery have been conducted for many purposes by simply assessing whether the surgery is cost-effective for specific questions related to the implantation of multifocal intraocular lenses, surgical techniques, optimizing assessments, preventing diseases or complications, etc. Moreover, although there are systematic reviews about cataract surgery and narrative reviews introducing the concept of economic evaluations, as far as we know, no previous study has been conducted that synthesizes and integrates evidence coming from both fields. Thus, the purpose of this narrative review is to introduce doctors and academics to economic evaluation tools, to describe how these have been historically applied to cataract surgery, and to provide special considerations for the correct interpretation of economic studies.

Rudolfsen JH, Olsen JA. Related variations: A novel approach for detecting patterns of regional variations in healthcare utilisation rates. PLoS One 2023; 18:e0287306. [PMID: 37347756 PMCID: PMC10286998 DOI: 10.1371/journal.pone.0287306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Accepted: 06/03/2023] [Indexed: 06/24/2023] Open
Abstract
Regional variations in healthcare utilisation rates are ubiquitous and persistent. In settings where an aggregate national health service budget is allocated primarily on a per capita basis, little regional variation in total healthcare utilisation rates will be observed. However, for specific treatments, large variations in utilisation rates are observed, iymplying a substitution effect at some point in service delivery. The current paper investigates the extent to which this substitution effect occurs within or between specialties, particularly distinguishing between emergency versus elective care. We used data from Statistics Norway and the Norwegian Patient Registry on eight somatic surgeries for all patients treated from 2010 to 2015. We calculated Diagnosis-Related Group (DRG) -weight per capita in 19 hospital regions. We applied principal component analysis (PCA) to demonstrate patterns in DRG-weight, annual relative changes in DRG-weight, and DRG-weight production for elective care. We show that treatments with similar characteristics cluster within regions. Treatment frequency explains 29% of the total variation in treatment rates. In a dynamic model, treatments with a high degree of emergency care are negatively correlated with treatments with a high degree of elective care. Furthermore, when considering only elective care treatments, the substitution effect occurs between specialties and explains 49% of the variation. When designing policies aimed at reducing regional variations in healthcare utilisation, a distinction between elective and emergency care as well as substitution effects need to be considered.

Economic Evaluation of Cataract: A Systematic Mapping Review. Ophthalmol Ther 2023; 12:789-807. [PMID: 36809595 PMCID: PMC10011294 DOI: 10.1007/s40123-023-00678-0] [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: 12/30/2022] [Accepted: 02/03/2023] [Indexed: 02/23/2023] Open
Abstract
INTRODUCTION The purpose of this article was to ascertain the existing literature and find the gaps in economic evaluations of cataracts. METHODS Systematic methods were used to search and collect the published literature on economic evaluations of cataracts. A mapping review of studies published in the following bibliographical databases was performed: the National Library of Medicine (PubMed), EMBASE, Web of Science (WOS), and the Central of Reviews and Dissemination (CRD) database. A descriptive analysis was conducted and relevant studies were classified into different groups. RESULTS Among 984 studies screened, 56 studies were included in the mapping review. Four research questions were answered. There has been a progressive increase of publications during the last decade. The majority of the included studies were published by authors from institutions in the USA and UK. The most commonly investigated area was cataract surgery followed by intraocular lenses (IOLs). The studies were classified into different categories according to the main outcome evaluated, such as comparisons between different surgical techniques, costs of the cataract surgery, second eye cataract surgery costs, quality of life gain after cataract surgery, waiting time of cataract surgery and costs, and cataract evaluation, follow-up, and costs. In the IOL classification, the most frequently studied area was the comparison between monofocal and multifocal IOLs, followed by the comparison between toric and monofocal IOLs. CONCLUSIONS Cataract surgery is a cost-effective procedure compared with other non-ophthalmic and ophthalmic interventions and surgery waiting time is an important factor to consider because vision loss has a huge and broad-ranging impact on society. Numerous gaps and inconsistencies are found among the studies included. For this reason, there is a need for further studies according to the classification described in the mapping review.

[PMID: 36803866 PMCID: PMC9940337 DOI: 10.1186/s12955-023-02096-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Accepted: 02/03/2023] [Indexed: 02/21/2023] Open
Abstract
BACKGROUND The EQ-5D-5L and 15D are generic preference-accompanied health status measures with similar dimensions. In this study, we aim to compare the measurement properties of the EQ-5D-5L and 15D descriptive systems and index values in a general population sample. METHODS In August 2021, an online cross-sectional survey was conducted in a representative adult general population sample (n = 1887). The EQ-5D-5L and 15D descriptive systems and index values were compared in terms of ceiling and floor, informativity (Shannon's Evenness index), agreement, convergent and known-groups validity for 41 chronic physical and mental health conditions. Danish value sets were used to compute index values for both instruments. As a sensitivity analysis, index values were also estimated using the Hungarian EQ-5D-5L and Norwegian 15D value sets. RESULTS Overall, 270 (8.6%) and 1030 (3.4*10-6%) unique profiles occurred on the EQ-5D-5L and 15D. The EQ-5D-5L dimensions (0.51-0.70) demonstrated better informativity than those of 15D (0.44-0.69). EQ-5D-5L and 15D dimensions capturing similar areas of health showed moderate or strong correlations (0.558-0.690). The vision, hearing, eating, speech, excretion and mental function 15D dimensions demonstrated very weak or weak correlations with all EQ-5D-5L dimensions, which may indicate potential room for EQ-5D-5L bolt-ons. The 15D index values showed lower ceiling than the EQ-5D-5L (21% vs. 36%). The mean index values were 0.86 for the Danish EQ-5D-5L, 0.87 for the Hungarian EQ-5D-5L, 0.91 for the Danish 15D and 0.81 for the Norwegian 15D. Strong correlations were found between the index values (Danish EQ-5D-5L vs. Danish 15D 0.671, Hungarian EQ-5D-5L vs. Norwegian 15D 0.638). Both instruments were able to discriminate between all chronic condition groups with moderate or large effect sizes (Danish EQ-5D-5L 0.688-3.810, Hungarian EQ-5D-5L 1.233-4.360, Danish 15D 0.623-3.018 and Norwegian 15D 1.064-3.816). Compared to the 15D, effect sizes were larger for the EQ-5D-5L in 88-93% of chronic condition groups. CONCLUSIONS This is the first study to compare the measurement properties of the EQ-5D-5L and 15D in a general population sample. Despite having 10 fewer dimensions, the EQ-5D-5L performed better than the 15D in many aspects. Our findings help to understand the differences between generic preference-accompanied measures and support resource allocation decisions.

A Cost-Utility Analysis of Robotic Arm-Assisted Total Hip Arthroplasty: Using Robotic Data from the Private Sector and Manual Data from the National Health Service. Adv Orthop 2022; 2022:5962260. [PMID: 35265378 PMCID: PMC8898863 DOI: 10.1155/2022/5962260] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 01/18/2022] [Accepted: 01/31/2022] [Indexed: 01/16/2023] Open
Abstract
Purpose The aim was to assess the cost-effectiveness of robotic arm-assisted total hip arthroplasty (rTHA) compared with manual total hip arthroplasty (mTHA) and to assess the influence of annual volume on the relative cost-effectiveness of rTHA. Methods A database of both rTHA (n = 48 performed in a private centre) and mTHA (n = 512 performed in the National Health Service) was used. Patient demographics, preoperative Oxford hip score, forgotten joint score, EuroQol 5-dimensional 3-level (EQ-5D), and postoperative EQ-5D were recorded. Two models for incremental cost-effectiveness ratios using cost per quality-adjusted life year (QALY) for rTHA were calculated based on a unit performing 100 rTHAs per year: 10-year follow-up and a lifetime time horizon (remaining life expectancy of a 69-year-old patient). Results When adjusting for confounding factors, rTHA was independently associated with a 0.091 (p=0.029) greater improvement in the EQ-5D compared to mTHA. This resulted in a 10-year time horizon cost per QALY for rTHA of £1,910 relative to mTHA, which increased to £2,349 per QALY when discounted (5%/year). When using the 10-year time horizon cost per QALY was approximately £3,000 for a centre undertaking 50 rTHAs per year and decreased to £1,000 for centre undertaking 200 rTHAs per year. Using a lifetime horizon, the incremental unadjusted cost per QALY gained was £980 and £1432 when discounted (5%/year) for rTHA compared with mTHA. Conclusions Despite the increased cost associated with rTHA, it was a cost-effective intervention relative to mTHA due to the associated greater health-related quality of health gain, according to the EQ-5D outcome measure.

Abstract
BACKGROUND This research aimed to review the theoretical and methodological aspects of the quality-adjusted life year (QALY) which give rise to potential for bias against certain patient populations, including those with problems with walking or an inability to walk (ambulatory disabilities), when health technology assessment decisions rely on QALY gain to show cost-effectiveness. Societal preferences for treating ambulatory versus non-ambulatory patients were also investigated. METHODS We reviewed published literature to identify information on theoretical underpinnings of the QALY, measurement of utilities for QALY assessment, and empirical evidence of societal preferences for the treatment of ambulatory and non-ambulatory patients. RESULTS AND DISCUSSION Health states which represent mobility impairment and the inability to walk receive low valuation from general public preferences. Non-ambulatory patients, for example those with advanced neuromuscular disease, have lower utilities determined by standardized preference-based measurement (PBM) tools. Any treatment that increases survival but could not restore ambulation would result in lower lifetime QALY gains for non-ambulatory versus ambulatory patients. Treatments could therefore potentially be deemed less cost-effective, or not cost-effective at all for this patient population.Empirical research indicates a societal preference for equal treatment of patients regardless of ambulatory status. The main limitation of our review was the non-systematic approach to evidence search and review, however, given the broad scope of content required to meet the aims of the review, we believe that the targeted approach was appropriate. The evidence presented in this article highlights the need for alternatives to strict QALY-based approaches to prevent avoidable health inequities when determining cost-effectiveness of healthcare interventions for non-ambulatory populations against fixed cost-effectiveness thresholds. An alternative metric, the Equal Value of Life Years Gained (evLYG), has been proposed as a supplementary measure for use alongside the QALY for its potential to alleviate bias against disabled patient populations during the assessment of healthcare treatments.

Abstract
PURPOSE Multifocal intraocular lenses (MIOLs) are effective in treating presbyopia before cataracts develop. This study measured health-related quality of life (HRQoL) and vision-related quality of life (VRQoL) after clear lens extraction (CLE) and MIOL implantation. DESIGN Before-and-after study METHODS: Patients were treated in Medilaser Coronaria, CorGroup, Oulu, Finland. HRQoL was measured by a generic 15-dimension (15D) instrument. VRQoL was measured with Visual Function Index-14 (VF-14) questionnaire. RESULTS CLE and MIOL implantation was performed in 137 patients. The patient age was 57 ± 6.2 years (mean ± standard deviation), and 58% were women. The near add was 2.1±0.3 diopters (D). The overall HRQoL 15D score increased from 0.938±0.058 to 0.955±0.057 at 6 months (P < .0001 vs baseline) and to 0.948±0.060 at 1 year (P = .02 vs baseline). The VRQoL VF14 score increased from 85.32±15.57 to 96.57±5.07 at 6 months (P < .0001 vs baseline) and to 96.61±6.48 at 1 year (P < .0001 vs baseline). The increase of HRQoL was correlated with the increase of VRQoL (P < .04). CONCLUSIONS CLE and MIOL implantation improved HRQoL and VRQoL compared to spectacles in this 1-year follow-up study. Improvement of HRQoL was correlated with VRQoL.

Abstract
OBJECTIVES To assess the effects of different types of cataract surgeries and intraocular lenses on generic as well as vision related quality of life of cataract patients, using EQ-5D and IND-VFQ 33 instruments respectively. METHODS An observational, longitudinal study of patients undergoing cataract surgery was carried out at three ophthalmology centres. Patients were prospectively admitted for surgery for age-related cataract. Generic quality of life was assessed by using Euroqol's EQ5D-5L questionnaire and vision related quality of life was assessed by the IND-VFQ-33 questionnaire. Data pertaining to vision function and quality of life were collected pre surgery and 4 weeks after the surgery. RESULTS Out of total patients (n = 814) recruited for the study, 517 patients were interviewed for both pre-surgery and post-surgery for EQ5D and 519 patients were interviewed for both pre-surgery and post-surgery for IND VFQ 33 tool. The combined data from all three centres showed that Quality Adjusted Life Year (QALY) gains observed in patients undergoing phacoemulsification with foldable lens implantation (2.25 QALY) were significantly higher (0.57 QALY) as compared to Small Incision Cataract Surgery (SICS) with PMMA lens implantation (1.68 QALY). Highest improvement however, in all three subscales of IND-VFQ-33 tool were clearly observed for SICS with PMMA lens implantation. CONCLUSIONS The study has elicited the Health related and vision related Quality of Life scores for cataract surgeries and subsequent lens implantation. This study also offers Health State Utility Values along with visual outcomes for different surgical procedures, lenses and for the combination of surgery with lens implantation for cataract procedures providing a useful resource for future economic evaluation studies.

Perceived burden of illness in patients entering for treatment in a university hospital – is the threshold to secondary care higher for patients with depression than for those with somatic disorders? Eur Psychiatry 2020; 26:441-5. [DOI: 10.1016/j.eurpsy.2010.09.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2010] [Revised: 09/23/2010] [Accepted: 09/23/2010] [Indexed: 11/22/2022] Open
Abstract
AbstractBackgroundThe threshold to secondary health care should be similar for all patients independent of the underlying disease. This study compared, using a validated health-related quality of life (HRQoL)-instrument, whether the perceived burden of illness is similar in patients admitted for secondary care treatment into a university hospital because of one of six common conditions.MethodsHRQoL, assessed by the generic 15D instrument before elective treatment, was compared in six groups: operative treatment of cataract (n = 219), operative treatment of cervical or lumbar radicular pain (n = 270), hysterectomy due to benign uterine conditions (n = 337), hip or knee replacement surgery (n = 223), coronary angiography due to suspected coronary artery disease (n = 261), and secondary care treatment of depression (n = 89).ResultsMean (±SD) HRQoL score was clearly highest in patients with benign uterine conditions (0.908 ± 0.071) and lowest in patients with depression (0.729 ± 0.120) (P < 0.001 between the groups). Also all the other groups had a significantly (P < 0.001) higher baseline HRQoL score (ranging from 0.802 to 0.824) than patients with depression. Outcome of treatment, in terms of HRQoL improvement, was in depressive patients at least equal, and in some cases even better, than that in the other groups.DiscussionOur results imply that, at least concerning perceived burden of illness, patients with depression are worse off when admitted to secondary care treatment than patients with many somatic conditions. That may be a consequence of poor motivation of depressive patients to seek treatment or that, contradictory to guidelines, the health care system does nor give priority to those worst off and sets a higher threshold for specialized care of patients with depression than of those with common somatic disorders.

Abstract
Effectiveness, efficacy and safety of biosimilar infliximab (CT-P13) in inflammatory bowel disease (IBD) patients has been shown in previous studies. Limited data exist on health-related quality of life (HRQoL) of switching originator to biosimilar infliximab (IFX) in IBD patients. The objective of this study was to evaluate impact of switching originator to biosimilar IFX on HRQoL, disease activity, and health care costs in IBD maintenance treatment.In this single-center prospective observational study, all IBD patients receiving maintenance IFX therapy were switched to biosimilar IFX. HRQoL was measured using the generic 15D health-related quality of life instrument (15D) utility measurement and the disease-specific Inflammatory Bowel Disease Questionnaire (IBDQ). Crohn Disease Activity Index (CDAI) or Partial Mayo Score (pMayo), and fecal calprotectin (FC) served for evaluation of disease activity. Data were collected at time of switching and 3 and 12 months after switching. Patients' characteristics, clinical background information and costs were collected from patient records and the hospital's electronic database.Fifty-four patients were included in the analysis. No statistically significant changes were observed in 15D, CDAI, pMayo, and FC during 1-year follow-up. IBDQ scores were higher (P = .018) in Crohn disease 3 months after switching than at time of switching. Costs of biosimilar IFX were one-third of costs of originator one. Total costs related to secondary health care (excluding costs of IFX), were similar before and after the onset of biosimilar IFX.HRQoL and disease activity were after switching from originator to biosimilar IFX comparable, but the costs of biosimilar IFX were only one-third of those of the originator one.

Surveying the Cost-Effectiveness of the 20 Procedures with the Largest Public Health Services Waiting Lists in Ireland: Implications for Ireland's Cost-Effectiveness Threshold. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2018; 21:897-904. [PMID: 30098666 DOI: 10.1016/j.jval.2018.02.013] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/29/2017] [Revised: 02/21/2018] [Accepted: 02/25/2018] [Indexed: 05/21/2023]
Abstract
OBJECTIVES To survey the cost effectiveness of procedures with the largest waiting lists in the Irish public health system to inform a reconsideration of Ireland's current cost-effectiveness threshold of €45,000/quality-adjusted life-year (QALY). METHODS Waiting list data for inpatient and day case procedures in the Irish public health system were obtained from the National Treatment Purchase Fund. The 20 interventions with the largest number of individuals waiting for inpatient and day case care were identified. The academic literature was searched to obtain cost-effectiveness estimates from Ireland and other high-income countries. Cost-effectiveness estimates from foreign studies were adjusted for differences in currency, purchasing power parity, and inflation. RESULTS Of the top 20 waiting list procedures, 17 had incremental cost-effectiveness ratios (ICERs) lower than €45,000/QALY, 14 fell below €20,000/QALY, and 10 fell below €10,000/QALY. Only one procedure had an ICER higher than the current threshold. Two procedures had ICERs reported for different patient and indication groups that lay on either side of the threshold. CONCLUSIONS Some cost-effective interventions that have large waiting lists may indicate resource misallocation and the threshold may be too high. An evidence-informed revision of the threshold may require a reduction to ensure it is consistent with its theoretical basis in the opportunity cost of other interventions foregone. A limitation of this study was the difficulty in matching specific procedures from waiting lists with ICER estimates from the literature. Nevertheless, our study represents a useful demonstration of a novel concept of using waiting list data to inform cost-effectiveness thresholds.

Abstract
BACKGROUND The costs of treating eating disorders are often considered high. AIMS The objective was to perform a cost-utility analysis to estimate the cost-effectiveness of treatment of anorexia nervosa (AN). METHODS Thirty-nine patients entering treatment of AN completed the 15D health-related quality-of-life (HRQoL) questionnaire before and 2 years after the start of treatment. Direct hospital costs were obtained. Quality-adjusted life years (QALYs) gained were calculated and cost-utility assessed. RESULTS Patients' baseline HRQoL was severely impaired. During follow-up, mean HRQoL improved statistically significantly. The cost per QALY gained was €5296 (best-case scenario) or €64 440 (base-case scenario) (€11 559 or €71 600 discounted 3%) depending on the assumptions used in the analysis. CONCLUSIONS The cost per QALY was in the same range as that of many other interventions provided in specialized medical care and within the limits usually considered acceptable, indicating that the treatment of AN is cost-effective.

Abstract
Purpose The aim of this study was to evaluate the operational impact of using preloaded intraocular lens (IOL) delivery systems compared with manually loaded IOL delivery processes during routine cataract surgeries. Methods Time and motion data, staff and surgery schedules, and cost accounting reports were collected across three sites located in the US, France, and Canada. Time and motion data were collected for manually loaded IOL processes and preloaded IOL delivery systems over four surgery days. Staff and surgery schedules and cost accounting reports were collected during the 2 months prior and after introduction of the preloaded IOL delivery system. Results The study included a total of 154 routine cataract surgeries across all three sites. Of these, 77 surgeries were performed using a preloaded IOL delivery system, and the remaining 77 surgeries were performed using a manual IOL delivery process. Across all three sites, use of the preloaded IOL delivery system significantly decreased mean total case time by 6.2%–12.0% (P<0.001 for data from Canada and the US and P<0.05 for data from France). Use of the preloaded delivery system also decreased surgeon lens time, surgeon delays, and eliminated lens touches during IOL preparation. Conclusion Compared to a manual IOL delivery process, use of a preloaded IOL delivery system for cataract surgery reduced total case time, total surgeon lens time, surgeon delays, and eliminated IOL touches. The time savings provided by the preloaded IOL delivery system provide an opportunity for sites to improve routine cataract surgery throughput without impacting surgeon or staff capacity.

Abstract
Cataract surgery is the most common ophthalmological surgical procedure, and it is predicted that the number of surgeries will increase significantly in the future. However, little is known about the recovery after surgery. The first aim of this study was to evaluate the prevalence, severity and duration of pain and other ocular discomfort symptoms experienced after cataract surgery. The other objectives were to identify the factors associated with lower postoperative patient satisfaction and to measure the effect of cataract surgery on patients' health-related quality of life (HRQoL) and visual function in everyday life. The study design was a prospective follow-up study. The course of the recovery and the presence of ocular symptoms were evaluated by interviewing the patients via a questionnaire at 1 day, 1 week, 6 weeks and one year after surgery The visual functioning in everyday life was measured with Visual Functioning Index VF-7 and Catquest-9SF-questionnaires and furthermore the HRQoL was measured with the 15D-instrument before surgery and at 12 months after surgery. The patients returned the questionnaires by mail and were interviewed in the hospital on the day of the surgery. The same patients filled-in all the questionnaires. The patient reports were used to collect the data on medical history. A total of 303 patients were approached at Kuopio University Hospital in 2010-2011 and of these 196 patients were eligible and willing to participate, with postoperative data being available from 186 (95%) patients. A systematic review article was included in the study procedure and it revealed the wide range in the reported incidence of postoperative ocular pain. Some of the identified randomized controlled studies reported no or only minor pain whereas in some studies significant pain or pain lasting for several weeks has been described in more than 50% of the study patients. In the present study setting, pain was reported by 34% during the first postoperative hours and by approximately 10% of patients during the first six weeks after surgery. During the early recovery in the hospital, only a minority of the patients reporting pain were provided with pain medication. The ocular discomfort symptoms such as itchiness, burning, foreign-body sensation and tearing were common both before (54%) and after surgery (38-52%). These symptoms can also be described as painful symptoms and are often difficult to distinguish from ocular pain. The symptoms are also typical of ocular surface disease, and some patients may benefit from the postoperative administration of tear substitutes. The patients reporting postoperative ocular symptoms were less satisfied with the treatment outcome at 12 months after surgery (p = 0.001) compared to the patients who experienced no symptoms. Those patients reporting less disability in visual functioning before surgery were more satisfied than patients with more reported disability. The HRQoL improved significantly after cataract surgery (p = 0.002). However, when compared to an age-and gender-standardized control population, in cataract subjects the HRQoL remained slightly worse both before and at 12 months after surgery.

Abstract
OBJECTIVE The published data on health-related quality of life (HRQoL) after treatment of nonfunctioning pituitary adenomas (NFPAs) are conflicting. We evaluated HRQoL in a recent series of patients who had surgery for an NFPA. DESIGN Cross-sectional study including a large control population. PATIENTS AND MEASUREMENTS A HRQoL questionnaire (15D) was sent to all patients (n = 161) having undergone transsphenoidal surgery for NFPA in the years 2000-2010 at the Helsinki University Hospital. The 15D score and dimension scores of the study population (n = 137) were compared with those of a large (n = 4967) gender- and age-standardized control population. Possible independent predictors of HRQoL in the patients were estimated with multivariate regression analysis. RESULTS Postoperatively, 57% of the patients had normal visual function. After a mean follow-up of 7·4 ± 3·2 years (mean ± SD), 62% suffered from hypopituitarism. Overall, HRQoL was near-normal in patients compared to controls (15D scores 0·885 ± 0·114 vs 0·903 ± 0·093, respectively, P = 0·07). On single dimensions, patients had impaired vision and sexual activity (both P < 0·0005), more depression and distress (both P < 0·005) and less discomfort and symptoms (P < 0·05). Age, body mass index, diabetes, depression and reoperation were independent predictors of impaired HRQoL (all P < 0·05). Thyroxine substitution was associated with impaired and hydrocortisone and testosterone substitution (males only) with better HRQoL (all P < 0·05). CONCLUSIONS This recent series of NFPA patients demonstrates that overall HRQoL is near-normal after medium term follow-up; the most impaired dimensions were in vision and sexual activity. Comorbidities are strong predictors of impaired HRQoL.

Abstract
PURPOSE Disease-specific instruments have shown significant gains in measuring health-related quality of life (HRQoL) in subjects having cataract surgery. However, the usage of generic instruments has resulted in conflicting evidence. METHODS In this prospective study, we have evaluated the impact of cataract surgery on subjects' HRQoL measured with a 15-dimension generic instrument, the 15D. The HRQoL of cataract subjects was compared with that of an age- and gender-standardized sample of the general population in Finland. A total of 152 subjects (mean age 74 years, 66% females) with a first-eye cataract surgery completed the 15D questionnaire both before and 12 months after cataract surgery. RESULTS When compared with the general population, cataract subjects had much lower HRQoL at baseline (mean difference 0.037 (95% CI: 0.020, 0.054), p < 0.001). At 12 months after cataract surgery, the overall utility index improved from the mean of 0.837 to 0.855 (mean difference 0.018 (95% CI: 0.007, 0.029), p = 0.002). Significant improvement was observed on the following five dimensions: seeing, moving, hearing, usual activities and discomfort/symptoms in the 15D questionnaire. CONCLUSION Our data indicate that at 12 months after first-eye cataract surgery, patients' HRQoL is slightly better than that before surgery. However, patients' postoperative HRQoL may remain lower than that of an age-and gender-standardized control population.

Abstract
Glucocorticoids are often required for adequate control of inflammation in many serious inflammatory diseases; common indications for long-term treatment include polymyalgia rheumatica, giant cell arteritis, asthma and chronic obstructive pulmonary disease. Long-term glucocorticoid therapy is, however, associated with many adverse effects involving skin, gastro-intestinal, eye, skeletal muscle, bone, adrenal, cardio-metabolic and neuropsychiatric systems. This balance between benefits and risks of glucocorticoids is important for clinical practice and glucocorticoid-related adverse effects can significantly impair health-related quality of life. Understanding the nature and mechanisms of glucocorticoid-related adverse effects may inform how patients are monitored for toxicity and identify those groups, such as older people, that may need closer monitoring. For clinical trials in diseases commonly treated with glucocorticoids, standardised measurement of glucocorticoid-related adverse effects would facilitate future evidence synthesis and meta-analysis.

Abstract
BACKGROUND Elective cataract surgery is the most commonly performed surgical procedure in developed countries. However, it is unclear whether cataract surgery on the second eye provides enough incremental benefit to be considered cost-effective. This study conducted a cost-effectiveness analysis of second-eye cataract surgery in the U.K. DESIGN A cost-effectiveness analysis. METHODS A decision-analytical model was developed to estimate the cost-effectiveness of second-eye cataract surgery, based on a comprehensive epidemiological and economic review to develop the parameters for the model. The model followed the clinical pathway of cohorts of patients receiving second-eye cataract surgery and included costs and health benefits associated with post-surgical complications. RESULTS In the model, second-eye surgery generated 0.68 additional quality-adjusted life years (QALY) with an incremental cost-effectiveness ratio of £1,964 per QALY gained. In sensitivity analyses, model results were most sensitive to changes in the health-related quality of life (HRQoL) gain associated with second-eye surgery, but otherwise robust to changes in parameter values. The probability that second-eye surgery is cost-effective at willingness to pay thresholds of £10,000 and £20,000 was 100%. CONCLUSION Second-eye cataract surgery is generally cost-effective based on the best available data and under most assumptions. However, there are only a small number of clinical trials for second-eye cataract surgery, and these have not been conducted in recent years.

Abstract
BACKGROUND Elective cataract surgery is the most commonly performed surgical procedure in the NHS. In bilateral cataracts, the eye with greatest vision impairment from cataract is operated on first. First-eye surgery can improve vision and quality of life. However, it is unclear whether or not cataract surgery on the second eye provides enough incremental benefit to be considered clinically effective and cost-effective. OBJECTIVE To conduct a systematic review of clinical effectiveness and analysis of cost-effectiveness of second-eye cataract surgery in England and Wales, based on an economic model informed by systematic reviews of cost-effectiveness and quality of life. DATA SOURCES Twelve electronic bibliographic databases, including MEDLINE, EMBASE, Web of Science, The Cochrane Library and the Centre for Reviews and Dissemination databases were searched from database inception to April 2013, with searches updated in July 2013. Reference lists of relevant publications were also checked and experts consulted. REVIEW METHODS Two reviewers independently screened references, extracted and checked data from the included studies and appraised their risk of bias. Based on the review of cost-effectiveness, a de novo economic model was developed to estimate the cost-effectiveness of second-eye surgery in bilateral cataract patients. The model is based on changes in quality of life following second-eye surgery and includes post-surgical complications. RESULTS Three randomised controlled trials (RCTs) of clinical effectiveness, three studies of cost-effectiveness and 10 studies of health-related quality of life (HRQoL) met the inclusion criteria for the systematic reviews and, where possible, were used to inform the economic analysis. Heterogeneity of studies precluded meta-analyses, and instead data were synthesised narratively. The RCTs assessed visual acuity, contrast sensitivity, stereopsis and several measures of HRQoL. Improvements in binocular visual acuity and contrast sensitivity were small and unlikely to be of clinical significance, but stereopsis was improved to a clinically meaningful extent following second-eye surgery. Studies did not provide evidence that second-eye surgery significantly affected HRQoL, apart from an improvement in the mental health component of HRQoL in one RCT. In the model, second-eye surgery generated 0.68 incremental quality-adjusted life-years with an incremental cost-effectiveness ratio of £1964. Model results were most sensitive to changes in the utility gain associated with second-eye surgery, but otherwise robust to changes in parameter values. The probability that second-eye surgery is cost-effective at willingness-to-pay thresholds of £10,000 and £20,000 is 100%. LIMITATIONS Clinical effectiveness studies were all conducted more than 9 years ago. Patients had good vision pre surgery which may not represent all patients eligible for second-eye surgery. For some vision-related patient-reported outcomes and HRQoL measures, thresholds for determining important clinical effects are either unclear or have not been determined. CONCLUSIONS Second-eye cataract surgery is generally cost-effective based on the best available data and under most assumptions. However, more up-to-date data are needed. A well-conducted RCT that reflects current populations and enables the estimation of health state utility values would be appropriate. Guidance is required on which vision-related, patient-reported outcomes are suitable for assessing effects of cataract surgery in the NHS and how these measures should be interpreted clinically.

Abstract
Background Cataract surgery has been shown to improve quality of life and household economy in the short term. However, it is unclear whether these benefits are sustained over time. This study aims to assess the six year impact of cataract surgery on health related quality of life (HRQoL), daily activities and economic poverty in Bangladesh and The Philippines. Methods and Findings This was a longitudinal study. At baseline people aged ≥50 years with visual impairment due to cataract (‘cases’) and age-, sex-matched controls without visual impairment were interviewed about vision specific and generic HRQoL, daily activities and economic indicators (household per capita expenditure, assets and self-rated wealth). Cases were offered free or subsidised cataract surgery. Cases and controls were re-interviewed approximately one and six years later. At baseline across the two countries there were 455 cases and 443 controls. Fifty percent of cases attended for surgery. Response rates at six years were 47% for operated cases and 53% for controls. At baseline cases had poorer health and vision related QoL, were less likely to undertake productive activities, more likely to receive assistance with activities and were poorer compared to controls (p<0.05). One year after surgery there were significant increases in HRQoL, participation and time spent in productive activities and per capita expenditure and reduction in assistance with activities so that the operated cases were similar to controls. These increases were still evident after six years with the exception that time spent on productive activities decreased among both cases and controls. Conclusion Cataract causing visual loss is associated with reduced HRQoL and economic poverty among older adults in low-income countries. Cataract surgery improves the HRQoL of the individual and economy of the household. The findings of this study suggest these benefits are sustained in the long term.

Abstract
This literature review is aimed at the evaluation of the potential for cataract prevention in Europe. It was performed using PubMed with Mesh and free-text terms. Studies included were (i) performed on a population of Caucasian origin at an age range of 40-95 years, (ii) cataract was clinically verified, (iii) drug record of prescriptions, their indication, a record of every diagnosis, dosage and quantity of prescribed medicine were available, (iv) sample size >300 and (v) published between 1990 and 2009. The results of 29 articles were reviewed. Former [3.75 (2.26-6.21)] or current smoking [2.34 (1.07-5.15)], diabetes of duration >10 years [2.72 (1.72-4.28)], asthma or chronic bronchitis [2.04 (1.04-3.81)], and cardiovascular disease [1.96 (1.22-3.14)] increased the risk of cataract. Cataract was more common in patients taking chlorpromazine during ≥90 days with a dosage ≥300 mg [8.8 (3.1-25.1)] and corticosteroids >5 years [3.25 (1.39-7.58)] in a daily dose >1600 mg [1.69 (1.17-2.43)]. Intake of a multivitamin/mineral formulation [2.00 (1.35-2.98)] or corticosteroids [2.12 (1.93-2.33)] also increased the risk of cataract. Corticosteroids applied orally [3.25 (1.39-7.58)], parenteral [1.56 (1.34-1.82)] or inhalational [1.58 (1.46-1.71)] lead to cataract more frequently than those applied topically: nasal [1.33 (1.21-1.45)], ear [1.31 (1.19-1.45)] or skin [1.43 (1.36-1.50)]. Outpatient cataract surgery was negatively associated with total cataract surgery costs, and chlorpromazine, corticosteroids and multivitamin/mineral formation increase the risk of posterior subcapsular cataract dependent on dose, treatment application and duration. This review presented a comprehensive overview of specific and general cataract risk factors and an update on most recent experimental studies and randomized control trials directed at cataract prevention.

Abstract
INTRODUCTION Glaucoma is a progressive optic neuropathy associated with neural rim loss of the optic disc and the retinal nerve fibre layer typically causing visual field (VF) deterioration. Generally, glaucomatous lesions in the eye and in the visual field progress slowly over the years. In population-based cross-sectional studies, the percentage of unilateral or bilateral visual impairment varied between 3-12%. In screening studies, 0.03-2.4% of patients have been found to suffer visual impairment. Glaucoma has previously been associated with substantial healthcare costs and resource consumption attributable to the treatment of the disease. The disease also causes reduction in health-related quality of life (HRQoL) in patients with glaucoma. OBJECTIVE AND METHODS This study compares patients with diagnosed open-angle glaucoma from two geographically different regions in Finland. A total of 168 patients were examined, 85 subjects from an area with higher per patient treatment costs (Oulu) and 83 patients from a region with lower per patient treatment costs (Turku). All patients had a history of continuous glaucoma medication use for a period of 11 years. For each patient, the total direct costs from glaucoma treatment were calculated and the total amount of resource consumption was determined from registries and patient records. Each patient underwent a clinical examination with visual field assessment and fundus photography. These data were used to determine the current stage of disease for each patient. Health-related quality of life questionnaire (15D) was used in determining each patient's subjective HRQoL score. RESULTS When applying the current diagnostic criteria for open-angle glaucoma, a total of 40% of patients did not to display any structural or functional damage suggesting glaucoma after 11 years of continuous medical treatment and follow-up. Patients with higher glaucoma stage (worse disease) were found to have statistically higher treatment costs compared with those at lower disease stages. Resource consumption was also greater in the patients in higher glaucoma stage. Patients in the Oulu district consumed more resources, and glaucoma treatment was more expensive than in the Turku area. The total treatment cost in Oulu and Turku was 6010 € and 4452 €, respectively, for the whole 11-year period. There was no statistically significant difference in quality-of-life scores between the two areas. No difference was noted between the higher-spending and lower-spending areas in this respect. However, when the population was analysed as a whole, patients with higher glaucoma stage were found to have lower vision-based 15D scores compared with those at lower disease stages. This observation was made also at both districts independently. CONCLUSIONS Major cost source in open-angle glaucoma treatment is medication, up to 74% of annual costs. In addition, it seems that higher resource consumption and higher treatment costs do not increase the patients' HRQoL as assessed by the 15D instrument.

Abstract
OBJECTIVE To evaluate with the best available clinical data in Japan the cost-effectiveness of cataract surgery through the estimation of the incremental costs per quality-adjusted life years (QALYs) gained. METHODS A Markov model with a probabilistic cohort analysis was constructed to calculate the incremental costs per QALY gained by cataract surgery in Japan. A 1-year cycle length and a 20-year horizon were applied. Best available evidence in Japan supplied the model with data on the course of cataract surgery. Uncertainty was explored using univariate and probabilistic sensitivity analysis. RESULTS In base case analysis, cataract surgery was associated with incremental costs of Japanese yen (¥) 551,513 (US$ 6,920) and incremental effectiveness of 3.38 QALYs per one cataract patient. The incremental cost effectiveness ratio (ICER) was ¥ 163,331 (US$ 2,049) per QALY. In Monte Carlo simulation, the average patient with cataract surgery accrued 4.65 [95 % confidence interval (CI): 2.75-5.69] more QALYs than patients without surgery, giving an ICER of ¥ 118,460 (95 % CI: 73,516-207,926) (US$ 1,486) per QALY. CONCLUSIONS Cataract surgery in Japan is highly cost-effective even when allowing for the uncertainty of the known variability that exists in estimates of the costs, utilities, and postoperative complication rate.

Abstract
PURPOSE It is necessary to develop tools for patient selection to target cataract surgery to patients with the best expected outcomes. We used visual acuity, visual functioning 14 (VF-14) test, the 15-dimension health-related quality-of-life questionnaire (15D) and the New Zealand priority criteria to evaluate the criteria for cataract surgery in a post hoc setting. MATERIAL AND METHODS Ninety-three consecutive patients living in a defined rural area in Finland had cataract surgery as a part of the Pyhäjärvi Cataract Study in 2003. Success of cataract surgery was defined as improvement of visual acuity by at least 2 lines and/or improvement of visual function measured by questionnaires. RESULTS The patients with a visual acuity of 0.30 logMAR (0.5 Snellen decimal) or worse in the better eye and/or 0.52 logMAR (0.3 Snellen decimal) in the worse eye had successful surgery in 59-83% of cases depending on the definition of success. When subjective judgement was added, the success rates varied between 63% and 91%. CONCLUSION Setting indication criteria, it seems sufficient to use two global questions in addition to visual acuity: one on the subjective view on disability, and one on a more neutral view on visual function, such as the 15D item on vision. The VF-14 did not perform any better than the single item counterparts.

Abstract
This paper uses the English Longitudinal Survey of Ageing to explore the self-reported effect of cataract operations on eye-sight. A non-parametric analysis shows clearly that most cataract patients report improved eye-sight after surgery and a parametric analysis provides further information: it shows that the beneficial effect is larger the worse was self-reported eye-sight preceding surgery so that those with very good or excellent eye-sight do not derive immediate benefit. Nevertheless, the long-run effect is suggested to be beneficial. Calibrating the results to existing studies of the effect of imperfect eye-sight on quality of life, the impact of cataract operations on Quality Adjusted Life Years is found to be similar to that established in previous studies and well above the costs of cataract operations in most circumstances.

Abstract
OBJECTIVE The costs of treating eating disorders are high. Our objective was to perform a cost-utility analysis of treatment of bulimia nervosa. METHOD 72 patients entering treatment of bulimia nervosa (ICD-10 diagnosis) completed the 15D health-related quality of life (HRQoL) questionnaire and the Eating Disorder Inventory (EDI) before and 6 months after the start of treatment. Quality-adjusted life years (QALYs) gained were calculated and cost-utility was assessed within the time horizon of 10 years. RESULTS Baseline HRQoL was severely impaired in the patients. As a consequence of treatment, mean HRQoL improved clinically and statistically significantly. The cost per QALY gained varied from €1,455 to €16,481 (from €4,428 to €19,663 discounted at 5%) depending on the assumptions used in the analysis. DISCUSSION HRQoL of bulimia nervosa patients is severely impaired, but treatment has a clear positive effect on HRQoL. The cost per QALY gained is comparable to many other treatments.

Abstract
OBJECTIVES The aim of this study was to elucidate, whether shift from first generation antipsychotics (FGA) to olanzapine can affect health-related quality of life (HRQoL) of residually symptomatic schizophrenic outpatients. METHODS Patients were randomized to either olanzapine or to continuation on their FGA. The 15D-measured HRQoL at baseline and end-point (after 12 weeks) was compared. RESULTS Patients (n = 21) randomized to olanzapine achieved better HRQoL than those (n = 21) who continued on their FGA. This difference on the 15D (0.048 on a 0-1 scale; p = .037) was clinically important and comparable to that resulting from common surgical interventions, for example, hip or knee replacement. CONCLUSIONS HRQoL of stable outpatients with residual symptoms or adverse effects may improve substantially after shift from FGAs to olanzapine.

Abstract
The effectiveness and cost-utility of nasal continuous positive airway pressure (nCPAP) treatment was evaluated in obstructive sleep apnoea syndrome (OSAS), using a 15D health-related quality of life (HRQoL) instrument in a routine clinical setting. In total, 78 OSAS patients (43 receiving nCPAP; 35 receiving lifestyle guidance) were included in the study. nCPAP treatment had a minor effect on the total HRQoL score; only the dimension of sleep improved in both groups. The mean ± SD number of quality-adjusted life years (QALYs) gained was 0.016 ± 2.34 in the nCPAP group and 0.386 ± 1.16 in the lifestyle guidance group. The mean cost per QALY gained was €73 375 for the nCPAP group and €845 for the lifestyle guidance group. The effect of nCPAP treatment on the HRQoL in a population of unselected OSAS patients was surprisingly small and the cost per QALY gained was high.

Abstract
The number of cataract extractions has increased substantially over time. At present, cataract surgery is estimated to be the most common single procedure performed in the developed world. The present study compares the costs of a cataract intervention across nine European countries. To enhance comparability, data were collected using a common template based on a case vignette. Adequate data for analysis were collected from 41 providers and were used to evaluate variation across countries and providers. Ordinary least squares and a multilevel model were used to investigate cost variation. Mean total costs per cataract intervention varied considerably from country to country, ranging from 318 euros in Hungary to 1087 euros in Italy. Variations of a similar magnitude were detected for personnel costs and overheads. However, variations in the cost of the lens were more modest. Overall, our results confirm expectations about the causes of cost variations across EU member states, indicating that these variations may be attributable to the quantity of resources used in performing the operation, the price of resources, and the type of setting in which the operation is performed. The study highlights how accounting practices and available cost data differ across Europe. It also shows the feasibility of collecting data on the basis of vignettes using common cost templates. Studies following this approach will gain importance if cross-country comparisons are to be used to promote European benchmarking exercises.

[PMID: 17383730 DOI: 10.1016/j.ophtha.2006.12.013] [Citation(s) in RCA: 103] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2006] [Revised: 12/14/2006] [Accepted: 12/14/2006] [Indexed: 10/23/2022] Open
Abstract
OBJECTIVE To determine the cost-effectiveness of cataract surgery worldwide and to compare it with the cost-effectiveness of comparable medical interventions. DESIGN Meta-analysis. PARTICIPANTS Approximately 12,000 eyes in the studies selected. METHODS Articles were identified by searching the literature using the phrase cataract surgery, in combination with the terms cost, cost-effectiveness, and cost-utility. Terms used for the comparable medical interventions search included epileptic surgery, hip arthroplasty, knee arthroplasty, carpal tunnel surgery, and defibrillator implantation. The search was restricted to the years 1995 through 2006. Cataract surgery costs were converted to 2004 United States dollars (US$). Cost-utility was calculated using: (1) costs discounted at 3% for 12 years with a discounted quality-adjusted life years (QALY) gain of 1.25 years, and (2) costs discounted at 3% for 5 years with a discounted QALY gain of 0.143 years. The Cataract Surgery Affordability Index (CSAI) for each country was calculated by dividing the cost of cataract surgery by the gross national income per capita for the year 2004. MAIN OUTCOME MEASURES Cost-utility in 2004 US$/QALY and affordability of cataract surgery relative to the United States. RESULTS Cost-utility values for cataract surgery (first eye) varied from $245 to $22,000/QALY in Western countries and from $9 to $1600 in developing countries. In developed countries, the cost-effectiveness of cataract surgery estimated by Choosing Interventions That Are Cost Effective ranged from, in international dollars (I$), I$730 to I$2400/disability-adjusted life years (DALY) averted, and I$90 to I$370/DALY averted in developing countries. The CSAI varied from 17% to 189% in developed countries and 29% to 133% in developing countries compared with the United States. The cost-utility of other comparable medical interventions was: epileptic surgery, $4000 to $20,000/QALY; hip arthroplasty, $2300 to $4800/QALY; knee arthroplasty, $6500 to $12,700/QALY; carpal tunnel surgery, $140 to $280/QALY; and defibrillator implantation, $700 to $23,000/QALY. CONCLUSIONS The cost-utility of cataract surgery varies substantially, depending how the benefit is assessed and on the duration of the assumed benefit. Cataract surgery is comparable in terms of cost-effectiveness to hip arthroplasty, is generally more cost-effective than either knee arthroplasty or defibrillator implantation, and is cost-effective when considered in absolute terms. The operation is considerably cheaper in Europe and Canada compared with the United States and is affordable in many developing countries, particularly India.
