General practitioner–pharmacist collaboration in Germany: an explanatory model

Abstract

Background In Germany, no validated measure and model of pharmacist-physician collaboration existed. Objectives To provide evidence for the factor structure of the previously validated Frequency of Inter-professional Collaboration Instrument and the Attitudes Toward Collaboration Instrument in measuring attitudes toward and frequency of collaboration from the general practitioner’s perspective in the context of primary care in Germany; to develop an explanatory model which illustrates factors influencing collaboration. Setting The study was conducted in the primary health care sector in Mecklenburg-Western Pomerania, Germany with a cohort of general practitioners. Method The two measures were translated into German and the survey was administered to 1438 practitioners. Exploratory factor analysis was used to assess the structure of the instruments. Structural equation modelling was used to determine how demographic variables and attitudes influence collaborative behaviour. Main outcome measure Outcome measure comprised frequency of and attitudes toward collaboration among German general practitioners and an explanatory model of practitioner-pharmacist collaboration. Results A response rate of 35.9% was achieved. Exploratory factor analysis revealed one factor for the instrument measuring attitudes and two factors for frequency. The factors were interpreted as ‘Communication and Collaboration’ and ‘Pharmacist medication management’. The significant demographic predictors of collaboration were age, population of the surgery’s location, distance to the pharmacy, specialty. Conclusion The results provide evidence for the factor structure of both measures in measuring attitudes toward and frequency of collaboration. A model of collaboration in which behaviour and extent of collaboration are directly influenced by individual and context characteristics is supported.
