Determining patient preferences in the management of neovascular age-related macular degeneration: a conjoint analysis.

PurposeTo determine the opinions from a patient perspective on relevant variables in the delivery of treatment for neovascular age-related macular degeneration (nAMD).MethodsPilot interviews with patients and doctors were conducted to identify what variables in the provision of a nAMD service were important. This led to the generation of two sets of scenario options. Subsequently 100 patients undergoing active treatment for nAMD in the National Health Service University Hospital, United Kingdom underwent interview assessment. They were asked to rank their preferences for provision of their care with reference to these two sets of scenario options. Using conjoint analysis, percentage preferences, and utility scores for each variable in each scenario design were calculated.ResultsNinety-five patients completed the preference ranking for both scenarios. Eight patients ranked worse vision as preferable to better vision and were excluded on the basis that they had not understood the task. The results of the remaining 87 patients are presented. The most important factor to patients was having good vision, followed by a one-stop service and less frequent follow up. The least important factors were label status of the drug, cost to the health service, and grade of the injector.ConclusionPatients regard good vision and minimal visits to the hospital above the status of injector, label status of drug, or cost to the NHS.

Intensive cataract training: a novel approach.

PURPOSE: To evaluate the safety of an intensive cataract surgery training programme. METHODS: An intensive cataract surgery training programme was implemented in August 2010 for year 3 ophthalmology trainees in the East Midlands Deanery North Rotation (United Kingdom). Trainees participated in extra-ocular surgery and 50 h of virtual reality cataract surgery simulator training over a 2-year period. Their third year comprised 6 months of intensive phacoemulsification training in a tertiary centre followed by a 6-month period of consolidation in a district general hospital. The complication rates and case numbers were evaluated after the first 2 years of implementation. RESULTS: At 2 years, three trainees had completed a full year of intensive training. In the first 6 months of training, Trainee 1 completed 156 cases, Trainee 2 completed 194 cases, and Trainee 3 completed 151 full cases as primary surgeons with an average rate of posterior capsule rupture (PCR) of 1%. At 12 months, Trainee 1 completed 291, Trainee 2 completed 318, and Trainee 3 completed 294 cases, with an average PCR rate of 0.66%. The trainees required 84 lists on average to complete 150 full cataract procedures. CONCLUSION: The combination of simulation and the new intensive training programme is safer than the traditional programme for cataract surgery training.

Second-eye cataract surgery in elderly women: a cost-utility analysis conducted alongside a randomized controlled trial.

AIM: The aim of this study was to evaluate the cost-effectiveness of second-eye cataract surgery for older women with minimal visual dysfunction in the eye to be operated on from a Health and Personal Social Services perspective, compared to waiting list controls who had already undergone first-eye cataract surgery. METHODS: A cost-utility analysis was undertaken alongside a randomized controlled trial of second-eye cataract surgery in secondary care ophthalmology clinics. A total of 239 women over 70 years old with one unoperated cataract were randomized to cataract surgery (expedited, approximately 4 weeks) or control (routine surgery, 12 months wait). Outcomes were measured in terms of quality-adjusted life years (QALYs), with health-related quality of life estimated using the EuroQol EQ-5D. RESULTS: The operated group had costs which were, on average, pound646 more than the control group (95% confidence interval, pound16-1276, P<0.04) and had a mean QALY gain of 0.015 (95% confidence interval, -0.039 to 0.068, P=0.59) per patient over 1 year. Therefore, the incremental cost-utility ratio was pound44,263 over the 1-year trial period. In an analysis modelling costs and benefits over patients' expected lifetime, the incremental cost per QALY was pound17,299, under conservative assumptions. CONCLUSIONS: Second-eye cataract surgery is not likely to be cost-effective in the short term for those with mild visual dysfunction pre-operation. In the long term, second-eye cataract surgery appears to be cost-effective unless carer costs are included.

Upper lid orbicularis oculi muscle strip and sequential brow suspension with autologous fascia lata is beneficial for selected patients with essential blepharospasm.

PURPOSE: Severe cases of blepharospasm resistant to botulinum toxin represent a challenging clinical problem. Over the last 10 years, we have adopted a staged surgical management of these cases with an initial upper lid orbicularis myectomy (combined with myectomy of procerus and corrugator supercilius as appropriate) and then 4-6 months later a brow suspension with autologous fascia lata. The aim of this study was to assess the outcome of this staged surgical approach. MATERIALS AND METHODS: A questionnaire was sent to all patients who had undergone the procedure and the clinical records reviewed. RESULTS: Fourteen patients had undergone the procedure of which 13 were alive. They were sent a questionnaire and 10 of them responded. All had both procedures. Eight of the 10 reported great benefit from the surgery, one some benefit, and one was worse off. All patients still required botulinum toxin injections after the surgery. CONCLUSIONS: Majority, but not all, of the patients in our series greatly benefitted from this staged surgical approach.

Views of glaucoma patients on provision of follow-up care; an assessment of patient preferences by conjoint analysis.

AIMS: To determine patients' preferences for provision of glaucoma follow-up services examining preferences for location, access and personnel for delivery of this care. METHODS: 100 patient patients attending the glaucoma outpatient clinic for follow-up review underwent an interview-based assessment during which they completed the visual function questionnaire 25 and ranking of scenario options for provision of follow-up care for their glaucoma. Percentage preferences for aspects of care offered in the conjoint analysis scenario packages and generation of utility values for each of the factor levels included in the scenario design were calculated. RESULTS: Travel time and training of health professional were the most important factors for patients (accounting for over 60%) of their preference. Utility scores were generated for each factor, with shorter travel time and examination by a doctor being the most important features to the patients. Patients who lived furthest from the hospital and had severe visual disability considered the number of visits to complete an episode to be an important feature. CONCLUSION: Patients ideally would like to travel a short distance and be seen by a doctor when being followed up for their glaucoma.

Falls and health status in elderly women following first eye cataract surgery: a randomised controlled trial.

BACKGROUND/AIM: A third of elderly people fall each year. Poor vision is associated with increased risk of falls. The authors aimed to determine if first eye cataract surgery reduces the risk of falling, and to measure associated health gain. METHODS: 306 women aged over 70, with cataract, were randomised to expedited (approximately 4 weeks) or routine (12 months wait) surgery. Falls were ascertained by diary, with follow up every 3 months. Health status was measured after 6 months. RESULTS: Visual function improved in the operated group (corrected binocular acuity improved by 0.25 logMAR units; 8% had acuity worse than 6/12 compared with 37% of controls). Over 12 months of follow up, 76 (49%) operated participants fell at least once, and 28 (18%) fell more than once. 69 (45%) unoperated participants fell at least once, 38 (25%) fell more than once. Rate of falling was reduced by 34% in the operated group (rate ratio 0.66, 95% confidence interval 0.45 to 0.96, p = 0.03). Activity, anxiety, depression, confidence, visual disability, and handicap all improved in the operated group compared with the control group. Four participants in the operated group had fractures (3%), compared with 12 (8%) in the control group (p = 0.04). CONCLUSION: First eye cataract surgery reduces the rate of falling, and risk of fractures and improves visual function and general health status.

Views of older people on cataract surgery options: an assessment of preferences by conjoint analysis.

BACKGROUND: Key issues in the quality of care for people with cataracts in the UK include hospital waiting lists, complication rates from surgery, and the use of junior surgeons. The main objective of this study was to investigate the relative importance that older people attach to these factors when given theoretical choices over options for cataract surgery. METHOD: A systematic sample of 194 individuals aged 60-84 years on a general practice register in Nottingham were invited to take part in an interview based survey. Respondents ranked 11 "cataract surgery packages" containing different waiting list lengths, complication risks, and surgeon grades. Conjoint analysis was performed to determine the relative importance of these factors for individuals and for the group as a whole. RESULTS: Of the 194 subjects invited to participate, 146 (72%) completed the interview. For the group as a whole the "averaged importance" of the factors was: complication risk 45.8%; waiting time 41.1%, surgeon grade 13.1%. Analysis of importance scores for individuals showed that some were particularly concerned about complication risk while others were more concerned about waiting times. There was a strong negative correlation between importance scores for these factors (Spearman's rho -0.78, p<0.001). CONCLUSIONS: Most respondents thought that either risk of damage to sight and/or waiting time were important, while surgeon grade was relatively unimportant. The findings show that some potential cataract patients prefer a greater risk of complication combined with a short wait than a low complication rate and a longer wait.
