Association Between Consecutive Days Worked by Intensivists and Outcomes for Critically Ill Patients

Two Weeks Versus One Week of Maximal Patient-Intensivist Continuity for Adult Medical Intensive Care Patients: A Two-Center Target Trial Emulation

OBJECTIVES

To compare outcomes for 2 weeks vs. 1 week of maximal patient-intensivist continuity in the ICU.

DESIGN

Retrospective cohort study.

SETTING

Two U.S. urban, teaching, medical ICUs where intensivists were scheduled for 2-week service blocks: site A was in the Midwest and site B was in the Northeast.

PATIENTS

Patients 18 years old or older admitted to a study ICU between March 1, 2017, and February 28, 2020.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We applied target trial emulation to compare admission during an intensivist's first week (as a proxy for 2 wk of maximal continuity) vs. admission during their second week (as a proxy for 1 wk of maximal continuity). Outcomes included hospital mortality, ICU length of stay, and, for mechanically ventilated patients, duration of ventilation. Exploratory outcomes included imaging, echocardiogram, and consultation orders. We used inverse probability weighting to adjust for baseline differences and random-effects meta-analysis to calculate overall effect estimates. Among 2571 patients, 1254 were admitted during an intensivist's first week and 1317 were admitted during a second week. At sites A and B, hospital mortality rates were 25.8% and 24.2%, median ICU length of stay were 4 and 2 days, and median mechanical ventilation durations were 3 and 3 days, respectively. There were no differences in adjusted mortality (odds ratio [OR], 1.01 [95% CI, 0.96-1.06]) or ICU length of stay (-0.25 d [-0.82 d to +0.32 d]) for 2 weeks vs. 1 week of maximal continuity. Among mechanically ventilated patients, there were no differences in adjusted mortality (OR, 1.00 [0.87-1.16]), ICU length of stay (+0.06 d [-0.78 d to +0.91 d]), or duration of mechanical ventilation (+0.37 d [-0.46 d to +1.21 d]) for 2 weeks vs. 1 week of maximal continuity.

CONCLUSIONS

Two weeks of maximal patient-intensivist continuity was not associated with differences in clinical outcomes compared with 1 week in two medical ICUs.

Measuring the Impact of ICU Strain on Mortality, After-Hours Discharge, Discharge Delay, Interhospital Transfer, and Readmission in Australia With the Activity Index

OBJECTIVES

ICU resource strain leads to adverse patient outcomes. Simple, well-validated measures of ICU strain are lacking. Our objective was to assess whether the "Activity index," an indicator developed during the COVID-19 pandemic, was a valid measure of ICU strain.

DESIGN

Retrospective national registry-based cohort study.

SETTING

One hundred seventy-five public and private hospitals in Australia (June 2020 through March 2022).

SUBJECTS

Two hundred seventy-seven thousand seven hundred thirty-seven adult ICU patients.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Data from the Australian and New Zealand Intensive Care Society Adult Patient Database were matched to the Critical Health Resources Information System. The mean daily Activity index of each ICU (census total of "patients with 1:1 nursing" + "invasive ventilation" + "renal replacement" + "extracorporeal membrane oxygenation" + "active COVID-19," divided by total staffed ICU beds) during the patient's stay in the ICU was calculated. Patients were categorized as being in the ICU during very quiet (Activity index < 0.1), quiet (0.1 to < 0.6), intermediate (0.6 to < 1.1), busy (1.1 to < 1.6), or very busy time-periods (≥ 1.6). The primary outcome was in-hospital mortality. Secondary outcomes included after-hours discharge from the ICU, readmission to the ICU, interhospital transfer to another ICU, and delay in discharge from the ICU. Median Activity index was 0.87 (interquartile range, 0.40-1.24). Nineteen thousand one hundred seventy-seven patients died (6.9%). In-hospital mortality ranged from 2.4% during very quiet to 10.9% during very busy time-periods. After adjusting for confounders, being in an ICU during time-periods with higher Activity indices, was associated with an increased risk of in-hospital mortality (odds ratio [OR], 1.49; 99% CI, 1.38-1.60), after-hours discharge (OR, 1.27; 99% CI, 1.21-1.34), readmission (OR, 1.18; 99% CI, 1.09-1.28), interhospital transfer (OR, 1.92; 99% CI, 1.72-2.15), and less delay in ICU discharge (OR, 0.58; 99% CI, 0.55-0.62): findings consistent with ICU strain.

CONCLUSIONS

The Activity index is a simple and valid measure that identifies ICUs in which increasing strain leads to progressively worse patient outcomes.

Health and Well-Being of Intensive Care Unit Physicians: How to Ensure the Longevity of a Critical Specialty

A second epidemic of burnout, fatigue, anxiety, and moral distress has emerged concurrently with the coronavirus disease 2019 (COVID-19) pandemic, and critical care physicians are especially affected. This article reviews the history of burnout in health care workers, presents the signs and symptoms, discusses the specific impact of the COVID-19 pandemic on intensive care unit caregivers, and attempts to identify potential strategies to combat the Great Resignation disproportionately affecting health care workers. The article also focuses on how the specialty can amplify the voices and highlight the leadership potential of underrepresented minorities, physicians with disabilities, and the aging physician population.

The Influence of the COVID-19 Pandemic on Intensivists' Well-Being: A Qualitative Study

BACKGROUND

The COVID-19 pandemic has strained health care systems and has resulted in widespread critical care staffing shortages, negatively impacting the quality of care delivered.

RESEARCH QUESTION

How have hospitals' emergency responses to the pandemic influenced the well-being of frontline intensivists, and do any potential strategies exist to improve their well-being and to help preserve the critical care workforce?

STUDY DESIGN AND METHODS

We conducted semistructured interviews of intensivists at clusters of tertiary and community hospitals located in six regions across the United States between August and November 2020 using the "four S" framework of acute surge planning (ie, space, staff, stuff, and system) to organize the interview guide. We then used inductive thematic analysis to identify themes describing the influence of hospitals' emergency responses on intensivists' well-being.

RESULTS

Thirty-three intensivists from seven tertiary and six community hospitals participated. Intensivists reported experiencing substantial moral distress, particularly because of restricted visitor policies and their perceived negative impacts on patients, families, and staff. Intensivists also frequently reported burnout symptoms as a result of their experiences with patient death, exhaustion over the pandemic's duration, and perceived lack of support from colleagues and hospitals. We identified several potentially modifiable factors perceived to improve morale, including the proactive provision of mental health resources, establishment of formal backup schedules for physicians, and clear actions demonstrating that clinicians are valued by their institutions.

INTERPRETATION

Restrictive visitation policies contributed to moral distress as reported by intensivists, highlighting the need to reconsider the risks and benefits of these policies. We also identified several interventions as perceived by intensivists that may help to mitigate moral distress and to improve burnout as part of efforts to preserve the critical care workforce.
