Barriers and Facilitators to Initiating and Completing Time-Limited Trials in Critical Care.
A time-limited trial is an agreement between clinicians and patients or surrogate decision makers to use medical therapies over a defined period of time to see if the patient improves or deteriorates according to agreed-upon clinical milestones. Although time-limited trials are broadly advocated, there is little empirical evidence of the benefits and risks of time-limited trials, when they are initiated, when and why they succeed or fail, and what facilitates completion of them. Our study objectives were to 1) identify the purposes for which clinicians use time-limited trials and 2) identify barriers and facilitators to initiating and completing time-limited trials. ⋯ An understanding of barriers and facilitators to initiating and completing time-limited trials is an essential first step toward appropriate utilization of time-limited trials in the ICUs, as well as developing educational or communication interventions with clinicians to facilitate time-limited trial use. We provide practical suggestions on patient populations in whom time-limited trials may be successful, the setting, and clinicians likely to benefit from educational interventions, allowing clinicians to have a fuller sense of when and how to use time-limited trials.
