Which factors affect the implementation of geriatric recommendations by primary care physicians?

Area of Science:

• Geriatric Medicine
• Healthcare Implementation Science

Background:

• Outpatient comprehensive geriatric assessment (OCGAU) recommendations show variable implementation rates, ranging from 48.6% to 71%.
• Understanding factors influencing the adoption of geriatric recommendations is crucial for improving patient care.

Purpose of the Study:

• To identify factors associated with reduced implementation rates of geriatric recommendations by primary physicians.
• To analyze patient characteristics and physician factors influencing the uptake of geriatric assessments.

Main Methods:

• Retrospective analysis of medical records from an 8-year study period.
• Collected data included patient demographics, functional/cognitive status, comorbidities, and primary physician characteristics.
• Statistical analysis, including univariate and multivariate models, was used to identify implementation predictors.

Main Results:

• Out of 3,434 recommendations for 488 patients, only 47.6% were implemented.
• Patients with lower implementation rates (<25%) had higher Charlson Comorbidity Index Total Scores (CCITS) and lower functional scores (Barthel Index, IADL).
• Multivariate analysis confirmed that higher CCITS was significantly associated with lower recommendation implementation by primary physicians.

Conclusions:

• Primary physician implementation rates for geriatric recommendations require improvement.
• Strengthening communication and providing further geriatrics training for primary physicians are recommended.
• Addressing patient complexity, particularly high comorbidity, may be key to enhancing recommendation adoption.
