Injuries occurring in hospital staff attending medical emergency team (MET) calls--a prospective, observational study.

BACKGROUND

Clinical emergency response systems such as medical emergency teams (MET) have been implemented in many hospitals worldwide, but the effect that these systems have on injuries to hospital staff is unknown. The objective of this study was to determine the rate and nature of injuries occurring in hospital staff attending MET calls.

METHODS

This study was a prospective, observational study, using a structured interview, of 1265 MET call participants, in a 650 bed urban, teaching hospital. Data was collected on the number and the nature of injuries occurring in hospital staff attending MET calls.

RESULTS

Over 131 days, 248 MET calls were made. An average of 8.1 staff participated in each MET call. The overall injury rate was 13 (95% confidence interval (CI) 7-20) per 1000 MET participant attendances, and 70 (95% CI 38-102) per 1000 MET calls. One injured participant required time off-work, an injury requiring time off-work rate of 1 (95% CI 0-4) per 1000 MET participant attendances, or 4 (95% CI 0-27) per 1000 MET calls. The relative risk of sustaining an injury if the MET participant performed chest compressions, contacted patient body fluids on clothing or protective equipment, without direct contact to skin or mucosa, or lifted the patient or a patient body part was 11.0 (95% CI 4.2-28.6), 8.7 (95% CI 3.4-22.0) and 5.5 (95% CI 2.1-14.2), respectively.

CONCLUSION

The rate of injuries occurring to hospital staff attending MET calls is relatively low, and many injuries could be considered relatively minor.
