RESUMO
PURPOSE: To compare the cost and utility of scleral buckle (SB), pars plana vitrectomy (PPV), and PPV with SB (PPV/SB) for moderately complex rhegmatogenous retinal detachment repair. METHODS: Cost-utility analysis using data from the Primary Retinal Detachment Outcomes Study. The model estimated costs, lifetime utility, and lifetime cost per quality-adjusted life year for treatment of moderately complex rhegmatogenous retinal detachment with SB, PPV, or PPV/SB. Data from the Centers for Medicare and Medicaid Services were used to calculate costs in hospital and ambulatory surgery center settings. RESULTS: Total costs (2020 US dollars) for repair of a moderately complex rhegmatogenous retinal detachment in hospital (ambulatory surgery center) settings were $5,975 ($3,774) for the SB group, $8,125 ($5,082) for the PPV group, and $7,551 ($4,713) for the PPV/SB group. The estimated lifetime quality-adjusted life years gained were 5.4, 4.7, and 4.7 in the SB, PPV, and PPV/SB groups, respectively. The cost per quality-adjusted life year for hospital and ambulatory surgery center settings was $1,106 a ($699) for the SB group, $1729 ($1,081) for the PPV group, and $1,607 ($1,003) for the PPV/SB group. CONCLUSION: Scleral buckle, PPV, and PPV/SB yielded very favorable cost-utility results for the repair of moderately complex rhegmatogenous retinal detachment, with slightly better results for SB, compared with current willingness to pay standards.

PURPOSE: The impact of sociodemographic factors on the presentation and outcomes of rhegmatogenous retinal detachment (RRD) in the United States has not been described. We analyzed the impact of these factors on the presenting fovea-on or off status of RRD, single operation anatomic success (SOAS) of repair, and postoperative visual acuity (VA). DESIGN: Retrospective, single-center, cohort study. PARTICIPANTS: Participants included 4061 patients from Wills Eye Hospital/Mid Atlantic Retina from February 2015 to February 2020. METHODS: Sociodemographic factors including age, gender, race, and regional mean household income (MHI) as determined by ZIP code were recorded. The VA at baseline and 12 months post-RRD repair was recorded. Multiple regression analysis was used to evaluate the relationship between sociodemographic factors to fovea-on or off presentation of RRD, SOAS, and 12-month VA. MAIN OUTCOME MEASURES: Foveal attachment at presentation of RRD, SOAS, and 12-month VA. RESULTS: Older age (odds ratio [OR], 1.34 per decade, 95% confidence interval [CI], 1.27-1.41, P < 0.001), male gender (OR, 1.27, 95% CI, 1.11-1.45, P < 0.001), non-White race (OR, 2.41, 95% CI, 1.92-3.03, P < 0.001), and lower MHI (OR, 0.94 per $10 000, 95% CI, 0.91-0.98, P = 0.005) were independent risk factors for fovea-off presentation of RD. The need for reoperation to repair RRD within 90 days was independently associated with fovea-off presentation (OR, 1.47, 95% CI, 1.24-1.74, P < 0.001) and non-White race (OR, 1.72, 95% CI, 1.27-2.39, P < 0.001). Finally, 12-month postoperative VA was worse in patients who were fovea-off (P < 0.001), older (P = 0.041), male (P = 0.038), and non-White (P = 0.007) but was not related to MHI (P = 0.24). CONCLUSIONS: These findings reveal associations between the sociodemographic factors and the presentation and outcomes of RRD. Physicians should be aware that socioeconomic disparities can negatively impact the prognosis of patients with RRD. Further study confirming these findings and efforts to mitigate their effects are warranted and will be of interest to the greater ophthalmology community.

PURPOSE: To perform a cost-utility analysis and comparison between pneumatic retinopexy (PR) and pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD) repair. DESIGN: A cost-utility analysis using decision analysis. PARTICIPANTS: There were no participants. METHODS: A decision analysis model was constructed based on results from the Pneumatic Retinopexy versus Vitrectomy for the Management of Primary Rhegmatogenous Retinal Detachment Outcomes Randomized Trial to calculate the costs, lifetime usefulness, and lifetime cost per quality-adjusted life year (QALY) for the treatment of RRD with PR or PPV. Data from the Centers for Medicare and Medicaid Services were used to calculate the associated adjusted costs in facility and nonfacility practice settings. MAIN OUTCOME MEASURES: Cost of intervention, utility gain over natural history, QALY gained, and cost per QALY. RESULTS: The total imputed costs (all in 2019 United States dollars) for primary repair of RRD in facility and nonfacility settings were $4451 and $2456, respectively, in the PR group and $7108 and $4514, respectively, in the PPV group. The estimated lifetime QALYs gained were 5.9 and 5.4 in the PR and PPV groups, respectively. The cost per QALY for facility and nonfacility settings was $751 and $414, respectively, in the PR group and $1312 and $833, respectively, in the PPV group. CONCLUSIONS: Cost-utility analysis of both PR and PPV demonstrated excellent results for both methods for RRD repair, with the metrics for PR somewhat more favorable independent of the practice settings (facility or nonfacility based).

PURPOSE: To determine factors predictive of anatomic, visual, and financial outcomes after traditional and nontraditional primary pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RD). DESIGN: Retrospective interventional case series and cost comparison. METHODS: Participants: Total of 178 eyes (156 patients) with PR-repaired primary RD by a single surgeon at a clinical practice from January 2001 to December 2013 and followed for ≥1 year. The cohort had 2 subgroups: traditional (TPR) and nontraditional (NTPR) PR. MAIN OUTCOME MEASURES: Characteristics associated with best-corrected visual acuity (BCVA) and anatomic outcomes. Cost analysis and potential cost savings comparing PR to scleral buckle and vitrectomy. RESULTS: One hundred thirty-one of 178 eyes (73.5%) were successfully treated at 1 year (postoperative year 1): 72.8% (75/103) in TPR and 74.6% (56/75) in NTPR. Macula-off detachment (-0.44 logMAR, P < .001) and clock hours of RD (-0.84 logMAR, P < .001) correlated with improved BCVA; pseudophakia (0.26 logMAR, P = .002) and inferior retinal tears (0.62 logMAR, P = .009) correlated with worsening BCVA. Pseudophakia (-0.15, P = .03), inferior quadrant RD (-0.27, P < .001), and proliferative vitreoretinopathy (-0.68, P < .001) correlated with anatomic failure. Total average cost for TPR and NTPR was $1248.37 ± $882.11 and $1471.91 ± $942.84, respectively (P = .10). PR had a potential cost savings of 62% and 60.8% when compared to scleral buckle and vitrectomy, respectively. CONCLUSIONS: PR results in successful anatomic and visual outcomes in both TPR and NTPR repair of primary RD. Preoperative pseudophakia is associated with worse visual outcomes and less anatomic success. The cost of primary PR and subsequent procedures to achieve final anatomic success was not significantly different between TPR and NTPR, and supports the possible cost-effectiveness of expanded indications for PR.

PURPOSE: To evaluate the costs and cost-utility of examination for posterior vitreous detachment (PVD) and treatment of associated pathology, and of managing various other peripheral retinal disorders to prevent retinal detachment (RD). DESIGN: A decision analysis model of cost-utility. PARTICIPANTS: There were no participants. METHODS: Published retrospective data on the natural course of PVD, retinal tears, and lattice degeneration were used to quantitate the visual benefits of examination and treatment. Center for Medicare and Medicaid Services data were used to calculate associated modeled costs in a hospital/facility-based and nonfacility/ambulatory surgical center (ASC)-based setting. Published standards of utility for a given level of visual acuity were used to derive costs and quality-adjusted life years (QALYs). MAIN OUTCOME MEASURES: Cost of evaluation and treatment, utility of defined health states, QALY, and cost per QALY. RESULTS: The modeled cost of evaluation of a patient with PVD and treatment of associated pathology in the facility/hospital (nonfacility/ASC)-based setting was $65 to $190 ($25-$71) depending on whether a single or 2-examination protocol was used. The cost per QALY saved was $255 to $638/QALY ($100-$239/QALY). Treatment of a symptomatic horseshoe tear resulted in a net cost savings of $1749 ($1314) and improved utility, whereas treatment of an asymptomatic horseshoe tear resulted in $2981/QALY ($1436/QALY). Treatment of asymptomatic lattice degeneration in an eye in which the fellow eye had a history of RD resulted in $4414/QALY ($2187/QALY). CONCLUSIONS: Evaluation and management of incident acute PVD (and symptomatic horseshoe tears) offer a low cost and a favorable cost-utility (low $/QALY) as a result of the minimization of the cost and morbidity associated with the development of RD, thus justifying current practice standards.

BACKGROUND: Eyes sustaining open globe trauma are at high risk of severe visual impairment. Ocular injuries which result in visual loss invariably affect the posterior segment of the eye, and prevention of visual loss involves posterior segment (vitreoretinal) surgery. Despite improvements in vitreoretinal surgical techniques, outcomes in these patients remain unsatisfactory, and development of the intraocular scarring response proliferative vitreoretinopathy is the leading cause. Proliferative vitreoretinopathy is the most common cause of recurrent retinal detachment in these eyes; it is reported to occur in up to 45 % of cases. METHODS/DESIGN: The Adjunctive Steroid Combination in Ocular Trauma (ASCOT) trial is a multi-centre, double-masked, parallel-arm randomised controlled trial with an internal pilot designed to investigate the effectiveness and cost-effectiveness of using intravitreal and sub-Tenon's triamcinolone acetonide peri-operatively in patients undergoing vitrectomy following open globe trauma. In total, 300 eyes of 300 patients will be recruited and randomly allocated to one of two treatment groups. Both groups will receive standard surgical treatment and routine pre-operative and post-operative treatment and care. The treatment group will receive an adjunctive peri-operative steroid combination (triamcinolone acetonide) consisting of 4 mg/0.1 ml into the vitreous cavity and 40 mg/1 ml into the sub-Tenon's space. The trial incorporates a two-stage internal pilot to examine projected recruitment and retention rates. Progression criteria from the internal pilot study will enable us to determine whether to undertake the main trial. Patients and primary outcome assessors will be masked to treatment allocation. The primary outcome will be an improvement from baseline to 6 months of at least 10 on the corrected visual acuity as measured by ETDRS letter score. Secondary outcomes will be development of scarring, retinal detachment, intraocular pressure abnormalities, quality of life and public sector service use. DISCUSSION: This is the first powered, controlled clinical trial to investigate the use of adjunctive triamcinolone in patients undergoing vitrectomy following open globe trauma.

AIMS: To investigate associations between socioeconomic status, retinal detachment type and post-operative visual outcomes in southern New Zealand. METHODS: A retrospective review of all cases of rhegmatogenous retinal detachments in Dunedin Hospital over two years was performed. Patient demographics and macula involvement at presentation were the primary outcome measures. The New Zealand Deprivation Index was used to group patients into low (30% least deprived), medium (middle 40%) and high (30% most deprived). Patients were excluded if they were not from New Zealand, or had traumatic detachments. RESULTS: During the study period, 95 retinal detachments in 94 patients were managed in Dunedin Hospital. Only 15% of retinal detachments occurred in the most deprived. More deprived patients had longer delays before assessment in hospital (mean of 29.8 days versus 10.1 days for the least deprived and 12.8 days for the medium category, overall p=0.025). There was no evidence of an association between deprivation and macula-off status (overall p=0.650) or visual acuity at one or three months (p=0.063 and p=0.328 respectively). Nor was there an association between referral pathway and macula-off status (p=0.242). CONCLUSIONS: Retinal detachment in southern New Zealand may be less common amongst those with the most deprived socioeconomic status who also experience longer delays till first treatment; but there was no association between socioeconomic status and patients being macula-off at presentation, or having poorer visual outcomes. More targeted patient education towards our most deprived citizens may reduce delays in treatment, and result in better visual outcomes.

PURPOSE: To perform a short-term and a long-term cost-utility analysis of rhegmatogenous retinal detachment (RRD) surgery in Shanghai, China. METHODS: A total of 117 patients who underwent RRD surgery at Shanghai First People's Hospital, Affiliated Shanghai Jiaotong University, and then underwent follow-up for at least 1 year, were included in the study. Costs associated with RRD surgery and time trade-off utility values before and after surgery were recorded. Short-term analysis was made for 1 year. Quality-adjusted life years (QALYs) gained by RRD surgery over the lifetime were calculated at a 3% discount rate in the long-term analysis. This study used the bootstrap method in statistical analysis and one-way sensitivity analyses to test robustness of the results. RESULTS: Compared with no treatment, the mean incremental costs of RRD surgery was 11,384 Chinese yuan (CN¥) (US$1751); the mean additional QALYs gained was 0.05 (95% confidence interval [CI] 0.04-0.06) for 1 year and 0.88 (95% CI 0.64-1.13) for life expectancy; the incremental cost effectiveness ratio (ICER) was CN¥224,921 (US$34,603)/QALY for the short-term, and CN¥13,794 (US$2122)/QALY for the long-term. In short-term analysis, the ICER was CN¥150,087 (US$23,090)/QALY for scleral buckling surgery, and CN¥507,727 (US$78,112)/QALY for vitreous surgery. In the long-term analysis, the ICER was CN¥6280 (US$966)/QALY for scleral buckling, and CN¥30,756 (US$4732)/QALY for vitreous surgery. CONCLUSIONS: For RRD patients, surgery increases QALYs. In a 1-year analysis, surgery is not a cost-effective treatment, however it is cost-effective over the lifetime.

OBJECTIVE: To evaluate costs and treatment benefits of rhegmatogenous retinal detachment (RD) repair. DESIGN: A Markov model of cost-effectiveness and utility. PARTICIPANTS: There were no participants. METHODS: Published clinical trials (index studies) of pneumatic retinopexy (PR), scleral buckling (SB), pars plana vitrectomy (PPV), and laser prophylaxis were used to quantitate surgical management and visual benefits. Markov analysis, with data from the Center of Medicare and Medicaid Services, was used to calculate the adjusted costs of primary repair by each modality in a hospital-based and ambulatory surgery center (ASC) setting. MAIN OUTCOME MEASURES: Lines of visual acuity (VA) saved, cost of therapy, adjusted cost of therapy, cost per line saved, cost per line-year saved, and cost per quality-adjusted life years (QALY) saved. RESULTS: In the facility, hospital surgery setting, weighted cost for PR ranged from $3726 to $5901 depending on estimated success rate of primary repair. Weighted cost was $6770 for SB, $7940 for PPV, and $1955 for laser prophylaxis. The dollars per line saved ranged from $217 to $1346 depending on the procedure. Dollars per line-year saved ranged from $11 to $67. Dollars per QALY saved ranged from $362 to $2243. In the nonfacility, ASC surgery setting, weighted cost for PR ranged from $1961 to $3565 depending on the success rate of primary repair. The weighted costs for SB, PPV, and laser prophylaxis were $4873, $5793, and $1255, respectively. Dollars per line saved ranged from $139 to $982. The dollars per line-year saved ranged from $7 to $49, and the dollars per QALY saved ranged from $232 to $1637. CONCLUSIONS: Treatment and prevention of RD are extremely cost-effective when compared with other treatment of other retinal diseases regardless of treatment modality. Retinal detachment treatment costs did not vary widely, suggesting that providers can tailor patient treatments solely on the basis of optimizing anticipated results because there were no overriding differences in financial impact.

PURPOSE: To provide insight into the preoperative factors that affect outcome after pneumatic retinopexy (PR) for treatment of primary rhegmatogenous retinal detachment repair. Additionally, we sought to analyze the cost of rhegmatogenous retinal detachment repair in the United States to determine potential cost savings with pneumatic retinopexy. DESIGN: Single-center, retrospective, observational consecutive case series and third party payer-perspective comparative cost analysis. PARTICIPANTS: We included 141 eyes undergoing pneumatic retinopexy for the treatment of primary rhegmatogenous retinal detachment. METHODS: Preoperative characteristics, anatomic outcomes, and best-available visual acuity were collected. Anatomic and visual outcomes were analyzed based on the presence of selected preoperative factors. The primary cohort was divided into 2 groups based on preoperative characteristics: (1) traditional pneumatic retinopexy and (2) nontraditional pneumatic retinopexy. Comparative cost analyses were performed between pneumatic retinopexy, scleral buckling, and vitrectomy. MAIN OUTCOME MEASURES: Anatomic and visual outcomes at 6 months. RESULTS: Overall anatomic success was 78.7% and visual acuity improved significantly (logarithm of the minimum angle of resolution [logMAR] 0.48-0.25; P <0.005). A 97.6% final anatomic success rate was achieved. Anatomic outcomes were similar between traditional versus nontraditional (84.1% vs 74.4%; P = 0.16), phakic versus pseudophakic (79.1% vs 78.0%; P = 0.88), and macula-on versus macula-off (77.9% vs 81.1%; P = 0.68) groups. Anatomic failure was predicted by the presence of an inferior retinal break (P <0.005) or visible vitreous traction on a retinal break (P = 0.04). Visual outcomes were similar between each of the traditional versus nontraditional (logMAR 0.21 vs 0.27; P >0.05) and phakic versus pseudophakic groups (logMAR 0.23 vs 0.28; P >0.05). Visual outcomes were better in macula-on detachments compared with those in which the macula was detached (logMAR 0.18 vs 0.42; P <0.005). Annual health care cost savings in the United States ranging from $6 to $30 million are theoretically possible by increasing pneumatic retinopexy utilization from the current rate of 15% to 20%-35%. CONCLUSIONS: Pneumatic retinopexy is an effective treatment modality for primary rhegmatogenous retinal detachment. Anatomic and visual outcomes are similar for traditional and nontraditional preoperative inclusion criteria, as well as phakic and pseudophakic eyes. Inferior breaks and visible vitreous traction on a tear predicted failure. Increased utilization of pneumatic retinopexy would achieve significant cost savings while maintaining outcomes.

OBJECTIVES: To report the financial impact of using modern lens and vitreoretinal surgical techniques. MATERIALS AND METHOD: Bottom-up sterilization and consumables costs for new surgical techniques (microincisional coaxial phacoemulsification and transconjunctival sutureless vitrectomy) and the corresponding former techniques (phacoemulsification with 3.2-mm incision and 20G vitrectomy) were determined. These costs were compared to each other and to the target costs of the Diagnosis Related Groups for public hospitals (Groupes Homogènes de Séjours [GHS]) concerned, extracted from the analytic accounting data of the French National Cost Study (Étude Nationale des Coûts [ENC]) for 2009 (target=sum of sterilization costs posted under medical logistics, consumables, implantable medical devices, and special pharmaceuticals posted as direct expenses). RESULTS: For outpatient lens surgery with or without vitrectomy (GHS code: 02C05J): the ENC's target cost for 2009 was 339 out of a total of 1432. The cost detailed in this study was 4 % higher than the target cost when the procedure was performed using the former technique (3.2mm sutured incision) and 12 % lower when the procedure was performed using the new technique (1.8mm sutureless) after removing now unnecessary consumables and optimization of the technique. For level I retinal detachment surgeries (GHS code: 02C021): the ENC's 2009 target cost was 641 out of a total of 3091. The cost specified in this study was 1 % lower than the target cost when the procedure was done using the former technique (20-G vitrectomy) and 16 % less when the procedure was performed using the new technique (transconjunctival vitrectomy) after removal of now unnecessary consumables and optimization of the technique. DISCUSSION AND CONCLUSIONS: Contrary to generally accepted ideas, implementing modern techniques in ocular surgery can result in direct cost and sterilization savings when the operator takes advantage of the possibilities these techniques offer in terms of simplification of the procedures to do away with consumables that are no longer necessary.

PURPOSE: To estimate and compare the costs of scleral buckle (SB) and pars plana vitrectomy (PPV) for treatment of rhegmatogenous retinal detachment (RRD). DESIGN: Cost analysis based on published prospective data comparing SB and PPV for RRD repair. METHODS: The costs of initial surgery, postoperative retina-affecting procedures, and eventual cataract extraction resulting from SB and PPV for RRD repair were estimated for both phakic and pseudophakic or aphakic patients and then were compared. A univariate sensitivity analysis also was performed to examine the sensitivity of our estimations. RESULTS: When considering all costs, SB was 10.7% less expensive than PPV for RRD repair in phakic patients, whereas PPV was 12% less expensive than SB for RRD repair in pseudophakic or aphakic patients. These conclusions were robust in the sensitivity analysis. CONCLUSIONS: SB seems to offer a modest cost savings over PPV for repair of RRD in phakic patients. However, in pseudophakic and aphakic patients, PPV seems to be less expensive than SB.

OBJECTIVE: To report the clinical outcomes of highly active antiretroviral therapy (HAART)-naïve, human immunodeficiency virus (HIV)-positive patients with newly diagnosed cytomegalovirus (CMV) retinitis receiving intravitreal injections of a low-volume intermediate maintenance dose (1.0 mg/0.02 ml) of ganciclovir. DESIGN: Nonrandomized, retrospective, interventional series. PARTICIPANTS: A consecutive cohort of 34 eyes from 24 HAART-naïve patients with AIDS and diagnosed with CMV retinitis by retinal specialists at the Singapore Communicable Disease Centre. INTERVENTION: Patients received a maintenance dose of 1.0 mg/0.02 ml of intravitreal ganciclovir once weekly after standard induction therapy with 2.0 mg/0.04 ml of twice weekly intravitreal ganciclovir. MAIN OUTCOME MEASURES: Time to progression, visual acuity, and complications. Progression was observed using photographic documentation. RESULTS: The median time to progression was 152 days (mean, 380.1 days, 95% confidence interval, 240.8-519.4). The median follow-up was 95 days (mean, 207.9 days). Three eyes developed rhegmatogenous detachments, but there was no endophthalmitis after 1858 injections. Contralateral involvement of CMV retinitis occurred in 17.6% of the patients. The cost estimate for intravitreal injections over a 6-month period was 11.7% that of sustained-release implants for unilateral treatment and 11.1% that of daily continuous intravenous infusions and oral valganciclovir compared with bilateral treatments. CONCLUSIONS: Weekly low-volume, intermediate-dose (1.0 mg/0.02 ml) ganciclovir is an efficacious option in developing countries where newer options of sustained-release implants and oral valganciclovir are unavailable or prohibitively expensive. The regimen maintains a long time to progression, preserving vision while minimizing retinal toxicity complications.

PURPOSE: To determine the trends and outcomes for treating primary rhegmatogenous retinal detachment (RRD) in a nationwide population-based study in Taiwan. METHODS: We collected admission data during the period of 1997-2005, from the Taiwan National Health Insurance Research Database, a source that covers over 96% of Taiwan's 23 million citizens. Totally 28 911 patients with a first-time admission diagnosis of RRD (ICD-9-CM codes 361 to 361.07) and undergoing surgical treatment (scleral buckling (SB), pars plana vitrectomy (PPV), or their combination) were identified. The utilized operation type, 180-day readmission rate for recurrent retinal detachment, length of hospital stay, and admission charge were obtained. Contingency table/chi (2) test and t-test were employed for the statistical analysis. RESULTS: Primary PPV (with or without SB) was a primary procedure in 47.3% of cases in 1997. This rate rose significantly to 61.2% in 2005. A significant decrease in the total 180-day readmission rate occurred from 18.95% in 1997 to 13.81% in 2005. These rates also significantly decreased for each surgical modality (from 16.30 to 11.38% for SB, from 21.29 to 14.69% for PPV, and from 22.99 to 16.55% for PPV+SB). The length of hospital stay decreased for each surgical modality between 1997 and 2005. CONCLUSIONS: There was a significant trend towards more frequently employing primary PPV (with or without SB) for the management of primary RRD. In addition, significant improvements in the primary success rates were shown for each surgical modality group and for total samples between 1997 and 2005.

INTRODUCTION: Ophthalmological indications for traditional hospitalizations are not clearly established and should be updated with respect to both healthcare quality and economic considerations. We therefore analyzed the data of patients hospitalized in an ophthalmology department. PATIENTS AND METHOD: We prospectively analyzed the medical and socioeconomic charts of all patients hospitalized during a 2-month period (December 2006 and January 2007) in a single ophthalmology department. RESULTS: Over the 2 months, 349 patients were admitted (mean stay, 3 days), 324 of whom were operated. The main causes of admission were retinal detachments (n=103), injuries (n=33), endothelial cell failure (n=27), cataract (n=27), high ocular pressure (n=23), and corneal abscess (n=17). Admission was mainly guided by the surgeon's habits (n=135, 39%) and was not medically relevant but was generally motivated by financial considerations. Other hospital admissions were medically justified (intravenous injections, head positioning) but the hospitalization of patients living far from the hospital (n=46; 13%) could be limited by the development of housing made available to patients. CONCLUSION: Ophthalmological hospitalization is not always medically relevant and often is based on financial or housing constraints. More than half of the classical admissions should be switched to ambulatory patient care by adapting financial compensations to surgical costs or providing outpatient housing.

BACKGROUND: The application of Willingness To Pay (WTP) measurement with Contingent Valuation Method (CVM) to medical services is gradually increasing. Knowing what influences WTP is an important matter because validity of CVM in medical services remains controversial. The objective of this survey is to measure WTP for the treatment of typical acute illnesses and to analyze the factors affecting WTP. METHODS: A questionnaire survey was conducted over the Internet, in which 795 men and women between 40 and 59 years old responded to questions about WTP for medical expenses in three hypothetical scenarios: common cold (CC), retinal detachment (RD) and myocardiac infarction (MI). RESULTS: Mean WTP was $29.9 for CC, $2,233 for RD, and $8,976 for MI. WTP for RD and MI was lower in the low-income group. While WTP for CC did not vary with income, WTP was higher in groups whose current subjective fitness levels were low. CONCLUSION: Although WTP measurements are criticized frequently for their validity and reliability, they are still useful for determining the economic value of medical services. Based on the results of this study, it is deemed necessary to enhance safety nets for low-income earners in regards to serious illnesses that incur high medical expenses. Further, it is recommended that the rate of co-payments be set relatively high with respect to mild illnesses for which alternative services are available.

PURPOSE: To report the differences in cost of treatment and outcome in retinal detachment (RD) cases with and without proliferative vitreoretinopathy (PVR). METHODS: Analysis of clinical trial databases of RD observed in 190 eyes of 190 patients. Eyes were classified as no PVR, developing PVR, or established PVR. For each eye, total cost of treatment undertaken on Moorfields Eye Hospital vitreoretinal unit, final retinal status, and best-corrected visual acuity were recorded. RESULTS: Management of patients who developed PVR involved approximately double the resources of RD without PVR. Eyes with pre-exiting PVR had similar resource input to those with RD without PVR. Patients who developed PVR had a mean of 3.7 operations (including subsequent cataract surgery) compared to 1.8 and 2.1 respectively for noncomplicated RD and pre-existing PVR. Anatomic success and visual outcome was significantly worse in eyes with PVR. CONCLUSIONS: Treatment of eyes that developed PVR after initial surgery cost significantly more than eyes with no PVR or established PVR (P < 0.01). Improvements in the management of RD aimed at preventing PVR and advances in PVR treatment may have significant financial as well as clinical benefits.

PURPOSE: The purpose of this study was to report a reference case, patient preference-based, incremental, cost-utility analysis for treatments of retinal detachment associated with severe proliferative vitreoretinopathy (PVR). DESIGN: Computer-based economic model utilizing data from the Medicare health insurance system in the United States. METHODS: A cost-utility analysis compared vitreoretinal surgery using expanding gases and silicone oil therapy to the natural course of retinal detachment associated with severe PVR. The model applies long-term published visual data from the Silicone Study Group, time tradeoff utility analysis, decision analysis with Markov modeling, and discounting of costs and health benefits as per the Panel on Cost-Effectiveness in Health and Medicine. The major outcome measure was in year 2000 United States dollars per quality-adjusted life-year (dollars/QALY) gained. RESULTS: Vitreoretinal surgery for retinal detachment complicated by severe PVR, as compared with no treatment, resulted in a mean gain of 0.128-0.200 discounted (3% annual rate) quality-adjusted life-years per treated patient. Silicone oil (dollars/QALY gained of 40,252 dollars) was slightly more cost-effective than perfluoropropane (C(3)F(8)) gas (dollars/QALY gained of 46,926 dollars) in eyes with PVR without previous vitrectomy, whereas C(3)F(8) gas (dollars/QALY gained of 46,162 dollars) was more cost-effective than silicone oil (dollars/QALY gained of 62,383 dollars) with previous vitrectomy and PVR. Sensitivity analysis resulted in a dollars/QALY gained of 13,347 dollars when 10% of opposite eyes had a severe visual loss to 202,128 dollars when a discount rate of 10% was utilized and opposite eyes initially had good vision. CONCLUSIONS: The incremental expense of interventions for retinal detachment associated with PVR is cost-effective when compared with other widely accepted interventional therapies across diverse medical specialties.
