Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Attendance at the screening appointment. This will be recorded at the appointment (which takes place four weeks after the invitation letter is sent), by the screener entering the patient into the electronic appointment record database. Following the end of data collection a search will be conducted on the database to extract information on attendance, as well as other demographic variables, and information on rearranged appointments. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Assess which incentive scheme is most effective 2. The cost effectiveness of different incentives on increasing uptake. 3. The impact on equity - whether incentives may encourage different groups to attend screening that may otherwise have not. A measure of social deprivation status will be calculated from the postcode. The impact of distance from the screening centre and GP practice will aslo be considered. 4. The effect of the different interventions on the number of participants who actually consent to the screening procedure once they attend the screening clinic 1st Retinal Screen Ltd will provide the anonymised data including the cohort’s age, gender, deprivation status (calculated from postcode), and ethnicity (subject to availability). The data will be provided following the screening of all participants. If there are significant differences in screening uptake and the demographic/risk factor profile between incentive schemes then a more detailed calculation of the impact of incentives is planned. | — |
