Use of radiological facilities by general practitioners

Area of Science:

• Radiology
• General Practice
• Public Health

Background:

• Diagnostic radiology referrals by general practitioners (GPs) are a key component of healthcare delivery.
• Understanding referral patterns and their outcomes is crucial for optimizing resource allocation and patient care.

Purpose of the Study:

• To analyze the volume, types, and outcomes of direct diagnostic radiological referrals made by general practitioners in the Aberdeen area.
• To investigate factors influencing referral rates, such as practice type and geographic location.

Main Methods:

• Retrospective study of 11,360 direct referrals to diagnostic radiological facilities from Aberdeen GPs in 1973.
• Analysis of referral rates, examination types (chest X-ray, barium meal), and detection rates of abnormalities.
• Comparison of referral patterns between singlehanded and group practices, and urban versus rural practitioners.

Main Results:

• Referrals constituted approximately 12% of adult radiology in city departments; barium meals were half of outpatient contrast studies.
• Chest X-rays and barium meals were the most frequent procedures, with 34% of all examinations showing abnormalities.
• Referral rates varied: singlehanded and rural GPs referred fewer patients, especially those over 15 miles from the city.

Conclusions:

• General practitioner referrals represent a significant volume of diagnostic imaging, with a substantial detection rate of abnormalities.
• Practice characteristics (group vs. singlehanded) and location (urban vs. rural) influence radiology referral patterns.
• Further research into referral appropriateness and efficiency could enhance diagnostic radiology utilization.
