Evidence based primary care? A multi-tier, multiple stakeholder perspective from Chile.

Abstract

A new challenge in health policy is the implementation of evidence-based practice. It is useful to look at international experiences which go beyond the conventional USA and UK examples. Health sector restructuring in Chile has as its goals: using evidence-based decision-making to reduce variations of practice, contain costs and increase the effectiveness of clinical practice. A key area of change is within primary health care. But how does the implementation of evidence-based health care proceed in reality? In order to understand this, it was decided to assess the policy environment using stakeholder analysis. Fifteen stakeholders from the public health sector were interviewed in depth using a snowball strategy for sampling. Material relating to perceptions, thoughts and aspirations about evidence-based innovations in primary health care was collected. Content analysis of the material produced a matrix of criteria and indicators of operational power. Concepts of evidence and effectiveness are different according to the role of each stakeholder in the health system. Most innovations proposed by government are related to management and stakeholders considered them as not being evidence-based. Informal mechanisms of decision-making predominated over the formal. Political issues are more important than formal evidence. All stakeholders felt they had power to define policy criteria but not to implement them. Implementation difficulties are related to how the system is organized and the culture within each organization. Most stakeholders indicated the need for human resources with appropriate knowledge and personal skills in order to implement these changes. These findings reveal again the importance of human factors within organizations. Policy-making should consider such processual aspects in order to implement changes in practices in Chilean health care system more effectively.
