PERCEPTIONS AND COMPETENCE IN EVIDENCE-BASED MEDICINE: ARE SURGEONS GETTING BETTER? A QUESTIONNAIRE SURVEY OF MEMBERS OF THE DUTCH ORTHOPAEDIC ASSOCIATION



Abstract

Background: The Journal of Bone and Joint Surgery, American Edition (the Journal) recently initiated a section called “Evidence-Based Orthopaedics”. Furthermore, a Levels of Evidence rating is now used in the Journal to help readers in clinical decision-making. Little is known if this recent emphasis of Evidence-based Medicine (EBM) influenced surgeons’ perceptions about and competence in evidence-based medicine. Therefore, we examined perceptions and competence in evidence-based medicine among Dutch orthopaedic surgeons.

Methods: Members of the Dutch Orthopaedic Association were surveyed to examine surgeons’ attitudes towards evidence-based medicine and competence in evidence-based medicine. We evaluated perceptions using a newly developed instrument tailored to surgical practice. Univariate analysis, and a multivariable analysis using Generalized Estimating Equations were performed to model the competence instrument.

Results: 367 Surgeons responded (60%). Orthopaedic surgeons welcomed evidence-based medicine. Practical evidence-based medicine resources were perceived as the best methods to move from eminence-based to evidence-based practice. Four variables were significantly and positively associated with the competence instrument:

  1. 1) younger age, particularly age between 36 and 45 years,

  2. 2) experience of less than 10 years,

  3. 3) having a PhD degree, and

  4. 4) working in an academic or teaching setting.

The majority of the respondents (65%) were aware of the Journal’s evidence-based medicine section, and 20% used the Journal’s evidence-based medicine abstracts in clinical decision-making. This increased awareness in evidence-based medicine was also reflected in a frequent use of Cochrane reviews in clinical decision-making (27%). Surgeons who used the Journal’s evidence-based medicine abstracts and Cochrane reviews had significantly higher competence scores.

Conclusions: Evidence-based medicine is welcomed by Dutch orthopaedic surgeons. Recent emphasis of evidence-based medicine is reflected in an increased awareness about the Journal’s evidence-based medicine section, Levels of Evidence, and the largest evidence-based medicine resource: Cochrane reviews. Younger orthopaedic surgeons had better knowledge about evidence-based medicine. Development and use of evidence-based resources as well as pre-appraised summaries like the Journal’s evidence-based medicine abstracts and Cochrane reviews were perceived as the best way to move from eminence based- to evidence-based orthopaedic practice.
