Introduction

The patient care process is very complicated and generates discrepancies and errors that to a large extent can be prevented and avoided. For a positive outcome of patient care we therefore need a systematic approach to patient care including structures and processes. In modern care we normally have good or excellent structures, including diagnostic tools, medications and educated professionals. The main problem is probably the delivery, the process of care including routines, information, communication, responsibilities etc. Donobedian1 has described this in detail and this platform can be used to improve the use of medicines. The pharmacist in community and hospital care, in or outside a pharmacy can be the driving force for developing evidence based services based on pharmacy practice research (PPR).
