Primary care utilization patterns before and after lung cancer diagnosis

Area of Science:

• Oncology
• Health Services Research
• Geriatric Medicine

Background:

• Primary care is crucial for managing veteran health.
• Lung cancer diagnosis impacts healthcare utilization patterns.
• Understanding post-diagnosis care needs is essential for effective treatment.

Purpose of the Study:

• To evaluate changes in primary care utilization rates.
• To analyze utilization trends before and after lung cancer diagnosis.
• To identify specific conditions driving primary care visits.

Main Methods:

• Retrospective analysis of electronic medical records (1997-2005).
• Inclusion of 323 male veterans with incident lung cancers.
• Comparison of primary care visits in 12-month periods pre- and post-diagnosis using paired t-tests.

Main Results:

• Overall primary care utilization showed a non-significant decrease post-diagnosis.
• Utilization for acute conditions significantly decreased by 20% post-diagnosis (0.32 to 0.12 visits per person-month).
• Utilization for chronic conditions remained stable post-diagnosis (0.29 visits per person-month).

Conclusions:

• A significant decline in primary care visits for acute conditions was observed after lung cancer diagnosis.
• Stable utilization for chronic conditions suggests ongoing management needs.
• The decrease in acute condition visits may indicate pre-diagnostic symptoms were cancer-related.
