Interview protocols and ergonomics checklist for analysing overexertion back accidents among nursing personnel.
No documented strategy, including preventive strategies, for systematic investigation of overexertion back accidents among nursing personnel has yet been published. One aim of the present study was to develop standardized instruments for the systematic investigation of back accidents among nursing personnel in order to develop preventive strategies. Another aim was to produce a screening tool that could easily be used for identifying potential overexertion back accident hazards. Two structured interview protocols were developed, one for the injured person and one for the supervisor. An ergonomics checklist was designed for the most important spaces according to accident statistics: patient's room, corridor, toilet, and also one for 'other space', eg X-ray and treatment rooms. The instruments were developed by frequent discussions and adjustments in a task force of researchers and occupational health personnel. The protocols were tested in two steps before a final version was established. The construct validity and interobserver reliability of the checklist were tested by ten ergonomists, who checked a patient's room, a toilet and a corridor with some known hazards. The constructed validity agreement was 90% in 19 of 26 items in the checklist. The interobserver reliability had the same figures as the validity for all items in the checklist. The interview protocols and checklist appear to be suitable for systematic investigation of overexertion back accidents.
