Effects of an educational feedback strategy on physician utilization of thyroid function panels
The Journal of Family Practice
|May 1, 1979
Summary
Physician education on ordering thyroid function panels (TFPs) initially reduced test orders, but rates returned to baseline within six months. Senior residents showed better response than junior residents, suggesting other factors influence physician behavior.
Area of Science:
- Medical Education
- Health Services Research
- Clinical Practice Improvement
Background:
- Physician overutilization of clinical laboratory tests is a persistent issue.
- Previous interventions to modify physician ordering behavior have yielded limited success.
- Thyroid function panels (TFPs) are frequently ordered tests where overutilization may occur.
Purpose of the Study:
- To evaluate the effectiveness of an educational feedback strategy on physician TFP ordering behavior.
- To assess the sustainability of behavior change following the intervention.
- To identify potential differences in responsiveness to educational feedback among resident physicians.
Main Methods:
- An educational feedback intervention was implemented within a family medicine group practice.
- Thyroid function panel (TFP) ordering rates were monitored before and after the intervention.
- Data analysis compared ordering rates at baseline, three months, and six months post-intervention.
Main Results:
- TFP ordering rates significantly decreased in the three months following the educational feedback.
- Ordering rates returned to pre-intervention levels within six months, indicating a lack of sustained change.
- Senior residents demonstrated a more positive initial response to the feedback compared to junior residents.
Conclusions:
- Educational feedback alone has limited long-term impact on physician test ordering behavior.
- Factors beyond educational approaches significantly influence physician decision-making regarding test utilization.
- Further research is needed to explore multifaceted strategies for sustainable behavior change in clinical practice.

01:25Errors occurring during blood pressure monitoring
Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

01:29Therapeutic Drug Monitoring: Affecting Factors
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
01:22Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
