Mapping standard ophthalmic outcome sets to metrics currently reported in eight eye hospitals.

BACKGROUND: To determine alignment of proposed international standard outcomes sets for ophthalmic conditions to metrics currently reported by eye hospitals. METHODS: Mixed methods comparative benchmark study, including eight eye hospitals in Australia, India, Singapore, Sweden, U.K., and U.S. All are major international tertiary care and training centers in ophthalmology. Main outcome measure is consistency of ophthalmic outcomes measures reported. RESULTS: International agreed standard outcomes (ICHOM) sets are available for cataract surgery (10 metrics) and macular degeneration (7 metrics). The eight hospitals reported 22 different metrics for cataract surgery and 2 for macular degeneration, which showed only limited overlap with the proposed ICHOM metrics. None of the hospitals reported patient reported visual functioning or vision-related quality of life outcomes measures (PROMs). Three hospitals (38%) reported rates for uncomplicated cataract surgeries only. There was marked variation in how and at what point postoperatively visual outcomes following cataract, cornea, glaucoma, strabismus and oculoplastics procedures were reported. Seven (87.5%) measured post-operative infections and four (50%) measured 30 day unplanned reoperation rates. CONCLUSIONS: Outcomes reporting for ophthalmic conditions currently widely varies across hospitals internationally and does not include patient-reported outcomes. Reaching consensus on measures and consistency in data collection will allow meaningful comparisons and provide an evidence base enabling improved sharing of "best practices" to improve eye care globally. Implementation of international standards is still a major challenge and practice-based knowledge on measures should be one of the inputs of the international standardization process.

Multi-stakeholder perspectives in defining health services quality indicators and dimensions: a concept mapping based comparison for cataract care between Singapore and The Netherlands.

OBJECTIVE: This study aims to advance understanding of globally valid versus country-specific quality dimensions and indicators, as perceived by relevant stakeholders. It specifically addresses patient-level indicators for cataract surgery. DESIGN: A mixed-methods case study comparing Singapore and The Netherlands SETTING: Singapore (2017-2019) and The Netherlands (2014-2015). PARTICIPANTS: Stakeholder representatives of cataract care in Singapore and The Netherlands. INTERVENTION: Based on the previously identified complete set of stakeholders in The Netherlands, we identified stakeholders of cataract care in Singapore. Stakeholder representatives then established a multi-stakeholder perspective on the quality of cataract care using a concept mapping approach. This yielded a multidimensional cluster map based on multivariate statistical analyses. Consensus-based quality dimensions were subsequently defined during a plenary session. Thereafter, Singaporean dimensions were matched with dimensions obtained in The Netherlands to identify commonalities and differences. MAIN OUTCOME MEASURE: Health-services quality dimensions of cataract care. RESULTS: 19 Singaporean stakeholders representing patients, general practitioners, ophthalmologists, nurses, care providers, researchers and clinical auditors defined health-services quality of cataract care using the following eight dimensions: clinical outcome, patient outcomes, surgical process, surgical safety, patient experience, access, cost and standards of care. Compared with the Dutch results, 61% of the indicators were allocated to dimensions of comparable names and compositions. Considerable differences also existed in the composition of some dimensions and the importance attached to indicators. CONCLUSIONS AND RELEVANCE: This study on cataract care in Singapore and The Netherlands shows that cataract care quality measurement instruments can share a common international core. At the same time, it emphasises the importance of taking a country-specific multi-stakeholder approach to quality definition and measurement. Complementing an international core set with country-specific measures is required to ensure that the included dimensions and indicators adequately capture the country-specific quality views.

Shared Cared for Stable Glaucoma Patients: Economic Benefits and Patient-centered Outcomes of a Feasibility Trial.

PURPOSE: The purpose of this article is to assess the quality of care and economic benefits of a shared care model managing patients with stable glaucoma in a primary eye care (PEC) clinic compared with a tertiary specialist outpatient clinic (SOC) in Singapore. PATIENTS AND METHODS: A randomized equivalence feasibility trial was preformed comparing the PEC with SOC models. Participants recruited from the SOC had no visual field progression or change in management for at least 3 years, were on a maximum of a single glaucoma medication, had no previous tube-shunt implant and were at least 3-year posttrabeculectomy surgery.Primary outcomes were clinical assessment and management, economic benefits, and patient satisfaction. Differences were analyzed using equivalence testing and generalized odds ratios. RESULTS: The trial included 233 patients, consisting of 42.1% glaucoma disc suspects (PEC: 47.4%; SOC: 36.8%), 27.5% primary angle closure suspects (PEC: 25.0%; SOC: 29.9%), 13.7% with ocular hypertension (PEC: 13.8%; SOC: 13.7%), 3.9% with primary angle closure glaucoma (PEC: 4.3%; SOC: 3.4%), and 3.0% with primary open angle glaucoma (PEC: 1.7%; SOC: 4.3%). Glaucoma clinical care for patients at PEC was as good as SOC [rate difference, 6.83%; 95% confidence interval (CI), 2.84-11.12) and management (rate difference, 7.69%; 95% CI, 3.21-12.17). In 23 cases (9.9%), 5.2% at PEC and 14.5% at SOC, there was disconcordance with the gold standard of senior consultant. Patient satisfaction at the PEC was equally high when compared with SOC (generalized odds ratio, 1.43; CI, 0.50-2.00). Direct costs per patient visit were 43% lower at PEC compared with SOC. CONCLUSION: Managing stable glaucoma patients at a primary care setting is a cost saving, safe, and effective shared care while enhancing professional collaboration between hospital and community settings.

Patient flow improvement for an ophthalmic specialist outpatient clinic with aid of discrete event simulation and design of experiment.

Continuous improvement in process efficiency for specialist outpatient clinic (SOC) systems is increasingly being demanded due to the growth of the patient population in Singapore. In this paper, we propose a discrete event simulation (DES) model to represent the patient and information flow in an ophthalmic SOC system in the Singapore National Eye Centre (SNEC). Different improvement strategies to reduce the turnaround time for patients in the SOC were proposed and evaluated with the aid of the DES model and the Design of Experiment (DOE). Two strategies for better patient appointment scheduling and one strategy for dilation-free examination are estimated to have a significant impact on turnaround time for patients. One of the improvement strategies has been implemented in the actual SOC system in the SNEC with promising improvement reported.
