Insights
Hospitalized COVID-19 patients increasingly had full code status as the pandemic progressed. Limited resuscitation preferences, like do-not-attempt-resuscitation (DNAR) orders, significantly decreased over time, especially after March 2021.
Area of Science:
- Medical research
- Public health
- Clinical outcomes
Background:
- The COVID-19 pandemic presented unique challenges for hospitalized patients.
- Understanding patient preferences for medical interventions, such as code status, is crucial during public health crises.
Purpose of the Study:
- To analyze trends in code status orders among hospitalized COVID-19 patients.
- To identify factors influencing code status decisions over the course of the pandemic.
Main Methods:
- Retrospective cohort study of 3615 adult COVID-19 patients admitted between March 2020 and December 2021.
- Analysis of demographic data, outcomes, and code status orders during hospitalization.
- Multivariable analysis to determine predictors of code status.
Main Results:
- Full code status was most common (62.7%), followed by do-not-attempt-resuscitation (DNAR) (18.1%).
- Admission time was an independent predictor of code status (p=0.04), with limited resuscitation preferences decreasing over time.
- Other predictors included BMI, race, ICU stay, age, and comorbidity index.
Conclusions:
- Hospitalized COVID-19 patients were less likely to have DNAR or partial code status orders as the pandemic evolved.
- A notable decrease in limited resuscitation preferences occurred after March 2021.
- A trend towards decreased code status documentation was observed over time.
Abstract:
Our aim was to examine how code status orders for patients hospitalized with COVID-19 changed over time as the pandemic progressed and outcomes improved. This retrospective cohort study was performed at a single academic center in the United States. Adults admitted between March 1, 2020, and December 31, 2021, who tested positive for COVID-19, were included. The study period included four institutional hospitalization surges. Demographic and outcome data were collected and code status orders during admission were trended. Data were analyzed with multivariable analysis to identify predictors of code status. A total of 3615 patients were included with full code (62.7%) being the most common final code status order followed by do-not-attempt-resuscitation (DNAR) (18.1%). Time of admission (per every six months) was an independent predictor of final full compared to DNAR/partial code status (p = 0.04). Limited resuscitation preference (DNAR or partial) decreased from over 20% in the first two surges to 10.8% and 15.6% of patients in the last two surges. Other independent predictors of final code status included body mass index (p < 0.05), Black versus White race (0.64, p = 0.01), time spent in the intensive care unit (4.28, p = <0.001), age (2.11, p = <0.001), and Charlson comorbidity index (1.05, p = <0.001). Over time, adults admitted to the hospital with COVID-19 were less likely to have a DNAR or partial code status order with persistent decrease occurring after March 2021. A trend toward decreased code status documentation as the pandemic progressed was observed.
