Force field analysis of driving and restraining factors affecting the evidence-based decision-making in health systems; comparing two approaches

Abstract

BACKGROUND: All policies and decisions need evidence examined by scientific methods. Moving toward evidence-based decision-making (EBDM) as a change in organizations, especially health systems (HSs), is inevitable. This study was conducted to identify the factors affecting EBDM in HSs from two approaches and to score them. MATERIALS AND METHODS: A mixed-method study was carried out using the force field analysis regarding the change toward EBDM in HS in 2020. This study included six steps to identify and score the key driving forces (DFs) and restraining forces (RFs) to change toward the EBDM in HS: first, finding forces from literature; second, selecting key DFs and RFs through focus group discussion; third, scoring the first group of DFs and RFs by the experts through electronic forms; fourth, determining key DFs and RFs from the managers’ perspective using qualitative interviews; fifth, scoring the second group of DFs and RFs by the experts; and sixth, comparison between forces resulted from two approaches. RESULTS: According to the literature and experts’ opinions, “relevant, reliable, interpretable, and understandable evidence” and “interaction between researchers and decision-makers” were the strongest forces to change, and “lack of organizational commitment and support” and “lack of relevant/high-quality evidence” were the strongest forces against the change toward EBDM in HS. Further, based on managers’ perspective and scores by the experts, “suitable supervision and control” and “reforming the planning and decision-making system” were the strongest forces to change, and “inadequate knowledge of the managers and staff about the principles and contents of EBDM” and “issues beyond the authorities of managers” were the strongest forces against the change toward EBDM in HS. CONCLUSIONS: Based on the findings, HSs’ managers can focus to reduce RFs and promote DFs for implementing EBDM strategies, so they can provide better services by making more efficient decisions.
