Abstract
OBJECTIVES:
To determine if a restrictive visitor policy inadvertently lengthened the decision-making process for dying inpatients without coronavirus disease 2019.
DESIGN:
Regression discontinuity and time-to-event analysis.
SETTING:
Two large academic hospitals in a unified health system.
PATIENTS OR SUBJECTS:
Adult decedents who received greater than or equal to 1 day of ICU care during their terminal admission over a 12-month period.
INTERVENTIONS:
Implementation of a visit restriction policy.
MEASUREMENTS AND MAIN RESULTS:
We identified 940 adult decedents without coronavirus disease 2019 during the study period. For these patients, ICU length of stay was 0.8 days longer following policy implementation, although this effect was not statistically significant (95% CI, –2.3 to 3.8; p = 0.63). After excluding patients admitted before the policy but who died after implementation, we observed that ICU length of stay was 2.9 days longer post-policy (95% CI, 0.27–5.6; p = 0.03). A time-to-event analysis revealed that admission after policy implementation was associated with a significantly longer time to first do not resuscitate/do not intubate/comfort care order (adjusted hazard ratio, 2.2; 95% CI, 1.6–3.1; p < 0.0001).
CONCLUSIONS:
Policies restricting family presence may lead to longer ICU stays and delay decisions to limit treatment prior to death. Further policy evaluation and programs enabling access to family-centered care and palliative care during the ongoing coronavirus disease 2019 pandemic are imperative.
Policies limiting family presence in hospitals are ubiquitous during the coronavirus disease 2019 (COVID-19) pandemic (1). We hypothesized a restrictive visitor policy implemented at our institutions on March 21, 2020, inadvertently lengthened the decision-making process for dying inpatients without COVID-19.
METHODS
To test this hypothesis, we queried the electronic health record at Johns Hopkins Hospital and Bayview Medical Center and identified adult decedents who received greater than or equal to 1 day of ICU care during their terminal admission over a 12-month period (September 1, 2019, to August 31, 2020). Patients with COVID-19 (n = 106) were excluded from analysis.
We used a regression discontinuity (RD) design (2) and specified linear regression models adjusted for age, sex, and self-reported race to estimate the effects of the policy. The primary outcome was ICU length of stay (LOS). Secondary outcomes were hospital LOS and time to first do not resuscitate (DNR), do not intubate (DNI), or comfort care order. Each RD model included hospital admission date as an independent variable, a pre-/postvariable indicating hospital admission date relative to policy implementation, and an interaction term between admission date and the pre-/postvariable. We refer to the 33 patients who were admitted before and died after policy implementation as “crossover” patients. We hypothesized that crossover patients likely had goals of care conversations occurring closer to time of death (i.e., post-policy). Therefore, we conducted sensitivity analyses, varying the date of the policy cutoff, and excluding crossover patients. Additional methods and sensitivity analyses are described in Supplementary Methods (http://links.lww.com/CCM/G323). The data used in this study were obtained through an institutional review board exemption approved by Office of Human Subjects Research at Johns Hopkins School of Medicine.
RESULTS
There were 940 adult decedents without COVID-19 during the study period. Among these decedents, ICU LOS was 0.8 days longer following policy implementation, although this effect was not statistically significant (95% CI, –2.3 to 3.8; p = 0.63; Fig. 1A). After excluding the 33 crossover patients, we observed that ICU LOS was 2.9 days longer post-policy (95% CI, 0.27–5.6; p = 0.03; Fig. 1B).
We performed a sensitivity analysis of the RD models with crossover patients excluded by systematically varying the date of policy implementation in 30-day intervals over the course of the study. We observed the true policy implementation date had the largest effect size and was the only date for which the cutoff was statistically significant in covariate RD models (Fig. 1C).
We found a similar result when considering total hospital LOS, including (0.5 d; 95% CI, –4.6 to 5.5; p = 0.86; Supplemental Fig. 1A, http://links.lww.com/CCM/G324; legend, http://links.lww.com/CCM/G325) and excluding crossover patients (4.8 d; 95% CI, 0.85–8.79; p = 0.02; Supplemental Fig. 1B, http://links.lww.com/CCM/G324; legend, http://links.lww.com/CCM/G325).
Among the 685 patients in the time-to-event analysis (including crossover patients), admission after policy implementation was associated with a significantly longer time to first DNR/DNI/comfort care order (adjusted hazard ratio, 2.2; 95% CI, 1.6–3.1; p < 0.0001; Fig. 2).
DISCUSSION
Our findings suggest that a policy restricting family presence may have led to longer ICU stays and delayed decisions to limit treatment prior to death. This unintended consequence is particularly concerning when ICU beds become a scarce medical resource (3). The phenomenon appeared to decrease as locoregional COVID-19 positivity rates dropped and exceptions to the policy were granted with greater regularity. Further policy evaluation, as well as creative programs (4) enabling access to family-centered (1) and palliative care (5) during the ongoing COVID-19 pandemic, are imperative.
