Pharmacists' and nurses' attitudes toward pharmacist-nurse relations and pharmaceutical services were surveyed before and after the implementation of satellite pharmacies at a 600-bed teaching hospital. The same questionnaire was distributed two months before decentralization (phase 1) and nine months after decentralization was completed (phase 2). Sixty questions about the pharmacy services and the drug treatment process were to be answered using a seven-point, Likert-type scale. Overall response rates for the two phases were 62% and 45%, respectively. Pharmacists' satisfaction with all measured aspects of pharmaceutical services increased after decentralization of services; nurses' satisfaction increased for all measures except pharmacist-conducted medication histories. Pharmacists' satisfaction with the nursing department was greater after decentralized services were implemented. Most aspects of role conflict, one of four measured antecedents to interdepartmental conflict, improved subsequent to decentralization of services. Because of changes in personnel between the two phases of the study, the results may represent the opinions of different people, rather than actual changes in satisfaction. The attitudes of nurses and pharmacists toward overall distributive pharmaceutical services and toward certain aspects of interprofessional relations improved after pharmaceutical services were decentralized.
