Physician practice patterns and variation in the delivery of preventive services

Area of Science:

• Primary Care Medicine
• Health Services Research
• Quality Improvement

Background:

• Existing strategies for improving preventive services delivery (PSD) show limited effectiveness.
• A multidimensional approach examining physician attributes, practice processes, and context is needed to understand PSD.
• Identifying distinct configurations of physician practice characteristics (PPCs) may offer insights into optimizing care delivery.

Purpose of the Study:

• To identify naturally occurring configurations of physician practice characteristics (PPCs).
• To assess the association between these configurations and preventive services delivery (PSD).
• To examine variation in PSD within identified configurations.

Main Methods:

• Cross-sectional study involving 138 family physicians across 84 practices.
• Ethnographic and survey methods assessed physician knowledge, attitudes, tools, staff utilization, and practice patterns.
• Direct observation and medical record review measured PSD; cluster analysis identified PPC configurations; multilevel models tested hypotheses.

Main Results:

• Six distinct PPC configurations were identified.
• PSD varied significantly across configurations, but mean differences between the highest and lowest were modest (3.4-10.8 points).
• Observed variation in PSD within configurations was considerable, and initial hypotheses were not confirmed.

Conclusions:

• Diverse physician practice configurations can achieve comparable rates of preventive services delivery (PSD).
• Significant within-configuration variation suggests dynamic interactions between PPCs and contextual factors.
• Focusing on understanding and leveraging existing practice characteristics may be more beneficial for improving PSD than pursuing a single ideal model.
