Summary

This study assessed the practicality and validity of data collection instruments and recruitment procedures and assessed likely participation rates for a future national multi-centred study. The study was carried out in two general practices in the Highlands. Patients requiring new medication for more than three weeks were randomised to receive either a normal prescription or an instalment prescription. An instalment prescription allows repeated partial dispensing of the prescription item over a set time period. If the patient does not collect all the instalments, only the medicines dispensed are charged to the NHS and the balance remains in the pharmacy stock. The economic analysis examined the response rates achieved and levels of missing data associated with different methods of administering the economic evaluation questionnaires (service use questions, patient cost questionnaire and SF- 36). In addition, to inform sample size calculations for a future economic evaluation, descriptive statistics relating to costs and drug cost savings were calculated.
