Implementation of health care quality indicators for out-of-hospital emergencies: a systematic review.

Although many health care quality indicators have been defined for establishing a common, homogeneous, and reliable system for assessing emergency department care, less information is available on the use of indicators of quality in attending emergencies outside the hospital. We aimed to identify and analyze quality indicators that have appeared in the literature on out-of-hospital emergencies. This systematic review of the literature followed the ations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We developed protocols for searching 5 databases to locate studies using quality indicators to evaluate care in out-of-hospital emergencies. Studies were published between July 2017 and July 2018 in either English or Spanish. We identified 22 studies naming 333 quality indicators in out-of-hospital emergencies. The indicators were classified as clinical or nonclinical; within each of these 2 sets, we also identified domains, or subcategories. As nonclinical quality identifiers were more numerous in the literature, it seems that they are the ones most often used to assess out-of-hospital emergency care at this time. This finding leaves the door open to designing and implementing new indicators able to measure quality of care in this clinical setting.
