Time-limited trials of critical care

Many patients die in the ICU, often after long courses of aggressive interventions, with potentially nonbeneficial treatments. Surrogate decision makers are tasked with decisions to initiate or forgo treatments based on recommendations from clinicians in the face of prognostic uncertainty and emotional duress. A strategy that has been adopted by ICU clinicians to address this has been proposing a “time-limited trial” (TLT) of ICU-specific interventions. A TLT involves clinicians partnering with patients and their surrogate decision makers in a shared decision-making model, proposing initiation of treatments for a set time, evaluating for specific measures of what is considered beneficial, and deciding to continue treatment or stop if without benefit. Core elements of TLT include utilizing the multidisciplinary team caring for the patient, evaluating for any prior advanced care planning, using clear and concise communication, acknowledging uncertainty, and collaborating with palliative care teams (Vink EE, et al. Intensive Care Med. 2018;44:1369). Recent research about TLT in the ICU has found that when executed well, TLTs can improve quality of care and provide patients with the care they desire and can benefit from (Vink, et al). Additionally, the use of an education intervention for ICU clinicians regarding protocolled TLT interventions was associated with improved quality of family meetings, and, importantly, a reduced intensity and duration of ICU treatments (Chang DW, et al. JAMA Intern Med. 2021;181[6]:786).
