Musculoskeletal injuries among ERCP endoscopists in Canada: METHODS

Occupational injuriesPhysicians practising ERCP in Ontario were identified from a pre-existing database obtained by calling all hospitals with 100 or more beds. Physicians practising ERCP outside of Ontario were identified by calling ERCP endoscopists at each medical school in Canada, who then identified their local academic and community peers. A study package containing a cover letter, a two-page self-administered questionnaire and a stamped return envelope was mailed to the identified physicians. The return envelopes were numbered to keep track of who participated in the study. The results were kept anonymous. Nonrespondents were sent a second study package, with the same contents as the first mailing, approximately six weeks later.

Questionnaires

To increase the response rate, the questionnaire was kept as short as possible — one page printed on both sides. The physicians were asked about their ERCP practices. How long the physicians had been practising ERCP and how many ERCPs were performed annually were recorded (Table 1). Questions about whether the physicians experienced any musculoskeletal condition were followed by more questions related to their conditions. Physicians were then asked questions related to the physical risks involved in performing ERCP: the type of lead apron worn, the type of endoscope used (video versus fibre optic) and the frequency of breaks (defined by removing the lead apron between procedures). For ergonomic considerations, they were asked to include a sketch of their own radiology facilities. Physicians were also asked to rank a list of possible physical risk factors to the operator. Finally, physicians were asked whether they were interested in receiving an ergonomic assessment or learning more about preventive strategies related to ERCP. To keep the survey brief and the response rate high, questions did not involve details regarding work-up or diagnosis, or physicians’ musculoskeletal complaints. Pain symptoms were assumed to be related to repetitive strain injuries (RSIs), which is a general term covering a group of conditions that are all related to the wear and tear on the soft tissues of the body.

Design and statistical considerations

This was a cross-sectional, questionnaire-based, descriptive study. Results are primarily expressed as a percentage of the responses received. Nonparametric tests of significance, Z-tests and %2 tests were also performed on selected variables to compare respondents who reported having injuries with those who did not.
