Out-of-hospital patient transportation (retrieval) of critically ill patients occurs within highly complex environments. Adverse events are not uncommon. Incident monitoring provides a means to better understand such events. The aim of this study was to characterize incidents occurring during retrieval to provide a basis for developing corrective strategies. Four organizations contributed 125 reports, documenting 272 incidents; 91% of forms documented incidents as preventable. Incidents related to equipment (37%), patient care (26%), transport operations (11%), interpersonal communication (9%), planning or preparation (9%), retrieval staff (7%) and tasking (2%). Incidents occurred during patient transport to the receiving facility (26%), at patient origin (26%), during patient loading (20%), at the retrieval service base (18%) and receiving facility (9%). Contributing factors were system-based for 54% and humanbased for 42%. Haste (7.5%), equipment malfunctioning (7.2%) or missing (5.5%), failure to check (5.8%) and pressure to proceed (5.2%) were the most frequent contributing factors. Harm was documented in 59% of incidents with one death. Minimizing factors were good crew skills/teamwork (42%), checking equipment (17%) and patient (8%), patient monitors (15%), good luck (14%) and good interpersonal communication (4%). Incident monitoring provides sufficient insight into retrieval incidents to be a useful quality improvement tool for retrieval services. Information gathered suggested improvements in retrieval equipment design and use of alternative power sources, the use of pro formae for equipment checking, patient assessment, preparation for transportation and information transfer. Lessons from incidents in other areas applicable to retrieval should be linked for analysis with retrieval incidents.

Patient compliance has long been recognized to be a problem associated with drug treatment. Dosettes constitute a compliance aid; their aim is to maintain patient independence, while facilitating patient compliance. However, those patients most in need of such devices are the least likely to be able to manage them. It was therefore decided to examine incidents in which problems involving dosettes had been identified; 52 such incidents were found. Half the incidents involved filling errors, and most of these involved nurses; some incidents were potentially dangerous systematic errors. A second type of incident involved a problem with use, mainly caused by hurried or confused patients; these sporadic errors were less dangerous than filling errors. The remainder of the incidents involved patients taking medication in addition to the medication in the dosette. Recommendations include objectively assessing that a dosette is appropriate for the individual patient, and education about the need for compliance, meticulous care and checking when filling, and regular checks to confirm correct use.
