Insights
Most hepatitis B virus (HBV) serology test requests in France do not follow guidelines, leading to unnecessary costs. Improving physician adherence to HBV testing guidelines is crucial for accurate diagnosis and cost-efficiency.
Area of Science:
- Hepatology
- Clinical Pathology
- Public Health
Background:
- Hepatitis B virus (HBV) serology tests are vital for diagnosis and management.
- Adherence to French prescription guidelines for HBV serology is essential for appropriate medical care and resource allocation.
Purpose of the Study:
- To evaluate compliance with French HBV serology prescription guidelines.
- To determine the financial impact of inappropriate HBV test requests.
- To assess the accuracy of physicians' interpretation of HBV serology results.
Main Methods:
- A cross-sectional practice inquiry involving 118 prescriptions for HBV serology tests.
- Prospective data collection from laboratory heads and prescribing physicians in June 2005.
- Analysis of prescription details, clinical indications, and physician interpretations.
Main Results:
- 74% of prescriptions failed to comply with current guidelines, with 45% exhibiting vague wording.
- Inappropriate HBV serology test requests resulted in an additional cost of €43.41 per prescription.
- Physician interpretation of test results was rated as excellent in 27%, fair in 59%, and false in 14% of cases.
Conclusions:
- Significant non-compliance with HBV serology testing guidelines necessitates improved application in clinical practice.
- Enhanced in-service training for physicians on HBV testing protocols is recommended.
- Addressing guideline non-adherence can reduce healthcare costs and improve patient management.
Abstract:
The aim of this survey was to study the requests written for hepatitis B virus (HBV) serology tests to ascertain their compliance with French prescription guidelines; additional costs incurred by inappropriate requests were also determined, as was the appropriateness of the physicians' interpretation of the test results. This was a cross-sectional practice inquiry involving 118 prescriptions for HBV serology tests. Data were prospectively collected in June 2005 from laboratory heads and prescribing physicians. The prescriptions were written for 188 patients (64% women), aged 35 years on average, mostly by general practitioners (65%) and gynecologists (25%). Prescribing physicians reported the following clinical situations as their main reasons for ordering HBV serology tests: pregnancy (25%); vaccination (20%); acute hepatitis (18%) and screening a patient with a risk factor (19%). Failure to comply with current guidelines was noted in 74% of the prescriptions and vague wording in 45%. The additional cost due to ordering inappropriate serology tests was 43.41 euro per prescription. The physician's interpretation of the test results was considered excellent (27%), fair (59%) or false (14%). Guidelines for the prescribing of hepatitis B serology tests need to be more rigorously applied in daily clinical practice. City hospital networks should promote further in-service training for physicians.
