Outcomes in Patients Perceived as Receiving Excessive Care by ICU Physicians and Nurses: Differences Between Patients < 75 and ≥ 75 Years of Age?

BACKGROUND: The benefit of the ICU for older patients is often debated. There is little knowledge on subjective impressions of excessive care in ICU nurses and physicians combined with objective patient data in real-life cases. RESEARCH QUESTION: Is there a difference in treatment limitation decisions and 1-year outcomes in patients < 75 and ≥ 75 years of age, with and without concordant perceptions of excessive care by two or more ICU nurses and physicians? STUDY DESIGN AND METHODS: This was a reanalysis of the prospective observational DISPROPRICUS study, performed in 56 ICUs. Nurses and physicians completed a daily questionnaire about the appropriateness of care for each of their patients during a 28-day period in 2014. We compared the cumulative incidence of patients with concordant perceptions of excessive care, treatment limitation decisions, and the proportion of patients attaining the combined end point (death, poor quality of life, or not being at home) at 1 year across age groups via Cox regression with propensity score weighting and Fisher exact tests. RESULTS: Of 1,641 patients, 405 (25%) were ≥ 75 years of age. The cumulative incidence of concordant perceptions of excessive care was higher in older patients (13.6% vs 8.5%; P < .001). In patients with concordant perceptions of excessive care, we found no difference between age groups in risk of death (1-year mortality, 83% in both groups; P > .99; hazard ratio [HR] after weighting, 1.11; 95% CI, 0.74-1.65), treatment limitation decisions (33% vs 31%; HR after weighting, 1.11; 95% CI, 0.69-2.17), and reaching the combined end point at 1 year (90% vs 93%; P = .546). In patients without concordant perceptions of excessive care, we found a difference in risk of death (1-year mortality, 41% vs 30%; P < .001; HR after weighting, 1.38; 95% CI, 1.11-1.73) and treatment limitation decisions (11% vs 5%; P < .001; HR, 2.11; 95% CI, 1.37-3.27); however, treatment limitation decisions were mostly documented prior to ICU admission. The risk of reaching the combined end point was higher in the older adults (61.6% vs 52.8%; P < .001). INTERPRETATION: Although the incidence of perceptions of excessive care is slightly higher in older patients, there is no difference in treatment limitation decisions and 1-year outcomes between older and younger patients once patients are identified by concordant perceptions of excessive care. Additionally, in patients without concordant perceptions, the outcomes are worse in the older adults, pleading against ageism in ICU nurses and physicians.

Outcomes of ICU patients with and without perceptions of excessive care: a comparison between cancer and non-cancer patients.

BACKGROUND: Whether Intensive Care Unit (ICU) clinicians display unconscious bias towards cancer patients is unknown. The aim of this study was to compare the outcomes of critically ill patients with and without perceptions of excessive care (PECs) by ICU clinicians in patients with and without cancer. METHODS: This study is a sub-analysis of the large multicentre DISPROPRICUS study. Clinicians of 56 ICUs in Europe and the United States completed a daily questionnaire about the appropriateness of care during a 28-day period. We compared the cumulative incidence of patients with concordant PECs, treatment limitation decisions (TLDs) and death between patients with uncontrolled and controlled cancer, and patients without cancer. RESULTS: Of the 1641 patients, 117 (7.1%) had uncontrolled cancer and 270 (16.4%) had controlled cancer. The cumulative incidence of concordant PECs in patients with uncontrolled and controlled cancer versus patients without cancer was 20.5%, 8.1%, and 9.1% (p < 0.001 and p = 0.62, respectively). In patients with concordant PECs, we found no evidence for a difference in time from admission until death (HR 1.02, 95% CI 0.60-1.72 and HR 0.87, 95% CI 0.49-1.54) and TLDs (HR 0.81, 95% CI 0.33-1.99 and HR 0.70, 95% CI 0.27-1.81) across subgroups. In patients without concordant PECs, we found differences between the time from admission until death (HR 2.23, 95% CI 1.58-3.15 and 1.66, 95% CI 1.28-2.15), without a corresponding increase in time until TLDs (NA, p = 0.3 and 0.7) across subgroups. CONCLUSIONS: The absence of a difference in time from admission until TLDs and death in patients with concordant PECs makes bias by ICU clinicians towards cancer patients unlikely. However, the differences between the time from admission until death, without a corresponding increase in time until TLDs, suggest prognostic unawareness, uncertainty or optimism in ICU clinicians who did not provide PECs, more specifically in patients with uncontrolled cancer. This study highlights the need to improve intra- and interdisciplinary ethical reflection and subsequent decision-making at the ICU.
