Impact of Nurse Staffing Policy on Nurse Outcomes in Intensive Care Units: A National Longitudinal Study in the United States.
Article in Nursing in critical care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo ensure the adequate nurse staffing levels and retain intensive care unit (ICU) nurses, it is important to understand the impact of nurse staffing policies on nurse outcomes during the COVID-19 pandemic.
aimThis study examined the impact of nurse staffing policies in ICUs on nurse outcomes before and during the COVID-19 pandemic. STUDY
designWe conducted a secondary data analysis of a nationally representative sample of nurses working in ICUs. Data from the 2018 (before COVID-19) and 2022 (during COVID-19) National Sample Surveys of Registered Nurses (NSSRN) in the United States were used. The association between nurse staffing policies and nurse outcomes (job satisfaction, turnover and turnover due to burnout and inadequate staffing) in ICUs was examined using logistic regression analysis. A difference-in-differences analysis using the 2018 and 2022 NSSRN datasets was used to examine the longitudinal effects of the policy.
resultsIn the state fixed effects model, the nurse staffing policy in ICUs was not significantly associated with the likelihood of job satisfaction. Meanwhile, nurse staffing policy was negatively and significantly associated with nurse turnover. Thus, the presence of a nurse staffing policy may decrease the likelihood of turnover during the COVID-19 pandemic compared to the absence of a nurse staffing policy (β = -0.12, p = 0.013).
conclusionsThe nurse staffing policy in ICUs effectively reduced turnover during the COVID-19 pandemic. However, it was not significantly associated with job satisfaction, turnover due to burnout and turnover due to inadequate staffing. RELEVANCE TO CLINICAL PRACTICE: During the COVID-19 pandemic, nurse staffing policies could improve nurse retention in ICUs. To enhance nurses' job satisfaction and reduce burnout, further staffing policy development is necessary to improve the appropriate staffing levels among nurses.
