Background

A checklist is an algorithmic listing of actions to be performed in a given clinical setting, the goal being to ensure that no step will be forgotten. Although a seemingly simple intervention, checklists have a sound theoretical basis in principles of human factors engineering and have played a major role in some of the most significant successes achieved in the patient safety movement.

The field of cognitive psychology classifies most tasks as involving either schematic behavior, tasks performed reflexively or "on autopilot," or attentional behavior, which requires active planning and problem-solving. The types of error associated with each behavior are also different: failures of schematic behavior are called slips and occur due to lapses in concentration, distractions, or fatigue, whereas failures of attentional behavior are termed mistakes and often are caused by lack of experience or insufficient training. In health care, as in other industries, most errors are caused by slips rather than mistakes, and checklists represent a simple, elegant method to reduce the risk of slips. Flight preparation in aviation is a well-known example, as pilots and air-traffic controllers follow pre-takeoff checklists regardless of how many times they have carried out the tasks involved. By standardizing the list of steps to be followed, and formalizing the expectation that every step will be followed for every patient, checklists have the potential to greatly reduce errors due to slips.

Current Use of Checklists

Checklists are a remarkably useful tool in improving safety, but they are not a panacea. As checklists have been more widely implemented, it has become clear that their success depends on appropriately targeting the intervention and utilizing a careful implementation strategy.

Errors in clinical tasks that involve primarily attentional behavior—such as diagnostic errors or handoff errors—may require solutions focused on training, supervision, and decision support rather than standardizing behavior, and thus may not be an appropriate subject for a checklist. An effective checklist also requires consensus regarding required safety behaviors. The success of checklists in preventing central line infections and improving surgical safety resulted from the strong evidence base supporting each of the individual items in the checklist, and therefore checklists may not be successful in areas where the "gold standard" safety practices have yet to be determined.

When a checklist is appropriate, safety professionals must be aware that implementing a checklist is a complex sociotechnical endeavor, requiring frontline providers to not only change their approach to a specific task but to engage in cultural changes to enhance safety. Successful implementation of a checklist requires extensive preparatory work to maximize safety culture in the unit where checklists are to be used, engage leadership in rolling out and emphasizing the importance of the checklist, and rigorously analyze data to assess use of the checklist and associated clinical outcomes. Failure to engage in appropriate preparatory and monitoring before and after checklist implementation may explain why checklist use in real-world settings is often poor, contributing to disappointing results. Ethnographic studies of successful and unsuccessful checklist implementation have been instrumental in enhancing understanding of the barriers that can limit checklist utility.

Surgeons experienced 50% fewer positioning errors with laparoscopic procedure equipment when they used a structured checklist. 73% experienced wrong positioning in the control group, compared to 30% using a checklist. checklist. 40% experienced wrong settings and connections of equipment in the control group, compared to 23% using a checklist. 87% experienced one or more incidents with equipment in the control group, compared to 50% using a checklist.
