Do Health Systems Have Consistent Performance Across Locations and Is Consistency Associated With Higher Performance?

Area of Science:

• Health Services Research
• Quality Improvement
• Diabetes Care Management

Background:

• Healthcare systems aim for consistent patient care delivery across diverse settings.
• Variability in ambulatory clinic performance can impact overall health system quality and reputation.
• Understanding the relationship between care consistency and performance is crucial for strategic planning.

Purpose of the Study:

• To evaluate diabetes care performance consistency within health systems' ambulatory clinics.
• To determine if increased care consistency correlates with improved clinic performance.
• To identify factors influencing the delivery of high-performance and consistent care.

Main Methods:

• Analysis of diabetes care intermediate outcome measures from 661 ambulatory clinics (2007-2013).
• Comparison of health system performance consistency against propensity score-matched proxy systems.
• Statistical evaluation of the association between consistency improvements and performance gains.

Main Results:

• Health systems demonstrated greater diabetes care consistency than comparable proxy systems.
• No significant association was found between improvements in care consistency and enhanced clinic performance.
• Larger health systems are more likely to achieve both high and consistent care delivery.

Conclusions:

• While health systems exhibit consistent diabetes care, consistency alone does not guarantee performance improvement.
• Achieving both high performance and consistent care can bolster a health system's brand and mitigate financial risks.
• Further investigation into the drivers of consistent care within health systems is warranted.
