Background: There is a lack of baseline data about the workforce, and services provided by hospital pharmacists in New Zealand. Aim: To determine the composition of the hospital pharmacy workforce in New Zealand and the level of service provided Method: A questionnaire was sent to chief pharmacists at all 30 public hospitals employing a pharmacist in November 2001, and repeated in November 2003. Data were requested on staff numbers, vacancies, staff experience, training, validation, and pharmacy services provided. Results were analysed for all hospitals, and within groups. Results: 25 hospitals (83%) responded in both years. Hospitals varied widely in their funded and actual staffing levels and in the services delivered. Services (drug distribution, ward pharmacy, patient counselling, drug information, formulary and treatment guideline development) were provided to a greater extent and with more favourable staffing levels in the large hospitals. The median number of beds per full-time equivalent pharmacist was 50 but the variation across the hospitals was considerable with a range of 30 to 394 beds/full-time equivalent pharmacist in 2003.
