| Methods |
To evaluate the effects of giving trial participants a thank you card following each study visit, compared with not giving them a thank you card. |
| Data |
|
| Comparisons |
Intervention 1: a thank you card is sent to trial participants at 4.5 and 9 months after randomisation. The host trial includes routine weekly clinical follow‐up assessments (if the participant’s wound is yet to heal) and participants in this SWAT group will also be sent questionnaires for the next outcome assessment time point (at months 6 and 12) when due. Intervention 2: Standard practice for the host trial (i.e.no thank you card). The host trial includes routine weekly clinical follow‐up assessments (if the participant’s wound is yet to heal) and participants in this SWAT group will receive no further contact until the next outcome assessment time point (at months 6 and 12). |
| Outcomes |
Primary: questionnaire response rate, defined as the proportion of participants in each group who complete and return the questionnaire at the 6‐month follow‐up visit. Secondary: 1) Completeness of response (percentage of questions completed) at 6 months. 2) Whether a reminder notice is required (number of participants requiring a reminder mailing divided by the number of participants who were sent a questionnaire) at 6 months. 3) Cost of SWAT intervention per participant retained at 6 months. 4) Completeness of response, whether a reminder notice is required, and cost per participant retained at 12 months. |
