Evaluation and application of continuity measures in primary care settings

Area of Science:

• Primary Care Medicine
• Health Services Research
• Quality Improvement

Background:

• Physician-patient continuity is a key quality indicator in primary care.
• Existing measures of continuity may differ in their utility and application.
• Understanding continuity variations is crucial for improving healthcare delivery.

Purpose of the Study:

• To compare different measures of physician-patient continuity.
• To assess continuity across various primary care settings and diagnoses.
• To examine the relationship between continuity and healthcare utilization patterns.

Main Methods:

• Utilized simulated data and real-world data from five primary care settings.
• Applied three established measures of continuity.
• Analyzed continuity for specific diagnoses and compared it to population averages.
• Correlated continuity scores with prescribed and kept return visits and laboratory order rates.

Main Results:

• Significant site-specific differences in continuity were observed, persisting after visit adjustments.
• Continuity scores for selected diagnoses were generally higher than for the overall patient population.
• Continuity showed a positive correlation with the number of prescribed return visits, but not with kept visits or laboratory order rates.

Conclusions:

• Physician-patient continuity is a complex metric influenced by setting and diagnostic focus.
• The number of prescribed visits is a more relevant factor for continuity than kept visits or lab orders.
• Findings highlight the need for tailored strategies to enhance continuity in primary care quality improvement efforts.
