[Efficiency profile in the neurological referrals effectuate reference specialists: use case-mix system adjusted...

Area of Science:

• Primary Care Medicine
• Health Services Research
• Epidemiology

Context:

• Primary care teams (PCT) manage a large patient population, necessitating efficient referral practices.
• Understanding referral patterns and their drivers is crucial for optimizing healthcare resource allocation.
• The Adjusted Clinical Groups (ACG) system offers a method for standardizing patient populations based on morbidity.

Purpose:

• To evaluate the utility of the Adjusted Clinical Groups (ACG) system in analyzing referral rates and efficiency within primary care settings.
• To determine center-specific referral rates and neurological referral proportions.
• To calculate adjusted efficiency indexes (EI) for primary care teams.

Summary:

• A multicenter retrospective study analyzed 80,775 patients, examining referral rates, patient demographics, and morbidity using the ACG system.
• Referral rates varied significantly across centers, with an overall referral rate of 70.5 per 100 patients/year.
• Neurological referrals constituted a small fraction (2.5%) of total referrals, primarily for older patients with head pain/migraine.

Impact:

• The ACG system demonstrated a significant explanatory power (46.3%) for variability in patient visits and episodes, and 20.1% for referral variability.
• Adjusted Efficiency Indexes (EI) showed inter-center variability, suggesting potential for targeted quality improvement initiatives.
• The findings support the cautious interpretation of referral data, even after adjustments, and highlight the potential of ACG for enhancing clinical management and referral measurement in primary care.
