Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Patients’ knowledge about options, their preferences and readiness to make a decision, assessed using the Cataract Decision Quality Measure before and after pre-operative clinician consultation | — |
Secondary
| Measure | Time frame |
|---|---|
| The likely effectiveness and cost-effectiveness of the decision support tool and the need for a subsequent full-scale trial, assessed through analysis of the following themes: 1. Estimated sample size, and the most appropriate primary/secondary outcomes for a main trial assessed using the effect size 2. Recruitment and retention rates, comparing numbers of study completion, declines and screen failures against routine care volume over the recruitment period 3. Decision support costs estimated through analysis of the duration and staff costs of pre-operative assessment and data collection in the intervention arm compared to routine care arm 4. Potential cost savings from avoidance of high risk/low benefit surgery and avoiding costly complications and complication-induced visual disability 5. Quality and level of shared decision making assessed using the Observer OPTION5 instrument during pre-operative assessment 6. Patient and clinician experience of the use of decision support tools, assessed using qualitative interviews after the pre-operative assessment study visit 7. Acceptability of the decision aid to patients and clinicians, assessed using qualitative interviews after the pre-operative assessment study visit 8. Self-reported difficulty with vision, assessed using the Cat-PROM5 questionnaire pre- and post-operatively 9. Uptake of cataract surgical option following patient-clinician interaction when using CDA compared to routine care 10. Initial validation of the benefits prediction model developed earlier in the Programme for predicting self-reported Cat-PROM5 benefit from surgery, assessed pre and post-operatively | — |
