General practitioners

Area of Science:

  • Cardiology
  • Primary Care Medicine
  • Medical Education

Background:

  • Electrocardiogram (ECG) interpretation is crucial for diagnosing cardiac conditions in primary care.
  • Assessing the current practices and diagnostic accuracy of general practitioners (GPs) in ECG interpretation is essential.

Purpose of the Study:

  • To evaluate the usage and interpretation competence of general practitioners with electrocardiograms (ECGs).
  • To identify factors influencing ECG interpretation performance among GPs.
  • To understand the implications for primary care services and patient management.

Main Methods:

  • A postal questionnaire survey was distributed to general practitioners in a health district.
  • The survey included 15 sample electrocardiogram tracings to assess interpretation skills.

  • Response rate and self-reported frequency of ECG usage were recorded.

    • Main Results:

    • A 60% response rate was achieved, with 40% using ECGs monthly and 43% always/usually for suspected myocardial infarction.
    • GPs generally felt competent in recognizing abnormalities, with recent qualification, higher qualifications, and frequent usage correlating with better performance.
    • Despite perceived competence, 20% of respondents misdiagnosed unequivocal acute myocardial infarction.

    Conclusions:

    • While GPs report good overall competence, significant misdiagnosis rates for acute myocardial infarction highlight areas for improvement.
    • Findings suggest a need to enhance electrocardiogram interpretation training and support within primary care.
    • Improved ECG services are vital for effective management of patients with suspected myocardial infarction, especially with advancements like thrombolytic therapy.
