A nurse-led support intervention for the families of critically ill patients did little to ease families’ psychological symptoms, but it did improve their perception of staff communication and family-centered care in the intensive care unit.

The length of ICU stay was also significantly shorter and the in-unit death rate higher among patients whose families received the intervention – a finding that suggests difficult end-of-life choices may have been eased, reported Douglas B. White, MD, and his colleagues (N Engl J Med. 2018;378:2365-75).
“The intervention resulted in significant improvements in markers of the quality of decision making, including the patient- and family-centeredness of care and the quality of clinician-family communication. Taken together, these findings suggest that the intervention allowed surrogates to transition a patient’s treatment to comfort-focused care when doing so aligned with the patient’s values,” wrote Dr. White of the University of Pittsburgh. “A previous study that was conducted in the context of advanced illness suggested that treatment that accords with the patient’s preferences may lead to shorter survival among those who prioritize comfort over longevity.”
The trial randomized 1,420 patients and their family surrogates in five ICUs to usual care, or to the multicomponent family-support intervention. The primary outcome was change in the surrogates’ scores on the Hospital Anxiety Depression Scale (HADS) at 6 months. The secondary outcomes were changes in Impact of Event Scale (IES; a measure of posttraumatic stress) the Quality of Communication (QOC) scale, quality of clinician-family communication measured by the Patient Perception of Patient Centeredness (PPPC) scale and the mean length of ICU stay.
The intervention was delivered by nurses who received special training on communication and other skills needed to support the families of critically ill patients. Nurses met with families every day and arranged regular meetings with ICU clinicians. A quality improvement specialist incorporated the family support into daily work flow.
In a fully adjusted model, there was no significant between-group difference in the 6-month HADS scores (11.7 vs. 12 points). Likewise, there was no significant difference between the groups in the mean IES score at 6 months.
Family members in the active group did rate the quality of clinician-family communication as significantly better, and they also gave significantly higher ratings to the quality of patient- and family-centered care during the ICU stay.
The shorter length of stay was reflected in the time to death among patients who died during the stay (4.4 days in the intervention group vs. 6.8 days in the control group), although there was no significant difference in length of stay among patients who survived to discharge. Significantly more patients in the intervention group died in the ICU as well (36% vs. 28.5%); however, there was no significant difference in 6-month mortality (60.4% vs. 55.4%).
