Evidence based general practice: a retrospective study of interventions in one training practice

Area of Science:

• General Practice Research
• Evidence-Based Medicine
• Clinical Trial Methodology

Background:

• General practice interventions should ideally be supported by robust evidence.
• Assessing the evidence base for routine clinical decisions is crucial for quality improvement.

Purpose of the Study:

• To quantify the proportion of general practice interventions supported by clinical trial evidence.
• To evaluate the appropriateness of evidence evaluation methods in this setting.

Main Methods:

• Retrospective review of 122 doctor-patient consultations from a suburban general practice.
• Interventions were categorized based on evidence from randomized controlled trials (RCTs), non-experimental evidence, or lack thereof.

Main Results:

• 81% of 101 analyzed interventions were based on evidence.
• 31 interventions were supported by RCTs, and 51 by convincing non-experimental evidence.
• Data from 21 consultations were excluded due to insufficient information.

Conclusions:

• The majority of general practice interventions are evidence-based.
• Existing clinical trial methodologies may not be optimally suited for the general practice context.
