Adaption of a trigger tool to identify harmful incidents, no harm incidents, and near misses in prehospital emergency care of children.

backgroundThe emergency medical service (EMS) addresses all chief complaints across all ages in various contexts. Children in EMS present a particular challenge due to their unique anatomical and physical properties, which require specific training that EMS clinicians often report lacking. This combination exposes children to incidents threatening patient safety. The most common method to highlight incidents is the incident reporting system. Studies have shown underreporting of such incidents, highlighting the need for multiple methods to measure and enhance patient safety in EMS for children. Thus, the aim of this study was to modify and adapt the current Ambulance TT for road-based EMS (ATT) to a pediatric version (pATT) with a guide containing definitions of triggers.

methodsThe adaption of the ambulance trigger tool to a version suitable for children followed a stepwise manner, including (1) a review of previous literature to pinpoint areas of risk regarding patient safety among children in EMS. (2) Three sessions of expert panel discussions via video meetings were held to evaluate each trigger of the ATT in terms of clinical relevance, comprehensibility, language and areas of risk regarding patient safety among children in EMS. (3) Clinical use of the pATT along with Retrospective Record Review (RRR). (4) Calculation of Item-level validity index and positive predictive value (PPV) for each trigger. (5) calculate inter-rater reliability between two independent record reviewers.

resultsThe literature search revealed 422 respective 561 articles in Cinahl and Medline where headlines and abstracts were read to identify areas posing risks to patient safety in EMS for children. During the structured discussions, one trigger was added to the existing 19 derived from the ATT, and the trigger definitions were modified to suit children. The three most common triggers identified in the 900 randomly selected records were deviation from treatment guidelines (63.9%), incomplete documentation (48.3%), and the patient is non conveyed after EMS assessment (41.1%). The positive triggers were categorized into near miss (54.6%), no harm incident (5.8%), and harmful incident (0.4%). Inter-rater reliability testing showed excellent agreement.

conclusionThis study demonstrates the adaptation of an existing trigger tool (ATT) to one suitable for children. It also shows that the trigger tool, along with retrospective record review, is a feasible method to evaluate patient safety in EMS, thus complementing existing methods.
