Better nurse work environments associated with fewer readmissions and shorter length of stay among adults with ischemic stroke: A cross‐sectional analysis of United States hospitals

Abstract

Stroke is among the most common reasons for disability and death. Avoiding readmissions and long lengths of stay among ischemic stroke patients has benefits for patients and health care systems alike. Although reduced readmission rates among a variety of medical patients have been associated with better nurse work environments, it is unknown how the work environment might influence readmissions and length of stay for ischemic stroke patients. Using linked data sources, we conducted a cross-sectional analysis of 543 hospitals to evaluate the association between the nurse work environment and readmissions and length of stay for 175,467 hospitalized adult ischemic stroke patients. We utilized logistic regression models for readmission to estimate odds ratios (OR) and zero-truncated negative binomial models for length of stay to estimate the incident-rate ratio (IRR). Final models accounted for hospital and patient characteristics. Seven and 30-day readmission rates were 3.9% and 10.1% respectively and the average length of stay was 4.9 days. In hospitals with better nurse work environments ischemic stroke patients experienced lower odds of 7-and 30-day readmission (7-day OR, 0.96; 95% confidence interval [CI]: 0.93-0.99 and 30-day OR, 0.97; 95% CI: 0.94-0.99) and lower length of stay (IRR, 0.97; 95% CI: 0.95-0.99). The work environment is a modifiable feature of hospitals that should be considered when providing comprehensive stroke care and improving post-stroke outcomes.ischemic stroke, length of stay, nurse work environment, readmissionGlobally, stroke is the second highest cause of death and third highest reason for disability (Benjamin et al., 2017;Gorelick, 2019). Despite acute stroke management being highly protocolized, variation still exists with regard to patient outcomes (Kaufman et al., 2019;Messé et al., 2016). For example, readmission rates among stroke patients are as high as 13% with most readmissions being unplanned and many avoidable (Bambhroliya et al., 2018;Vahidy et al., 2017).Variations in outcomes, including readmissions and length of stay, have been attributed to patient factors, including age and underlying general health (

Nursing Resources Linked to Postsurgical Outcomes for Patients With Opioid Use Disorder

“…With each additional patient-per-nurse (ie, poorer nurse staffing), odds of 30-day readmission were 3 times higher for surgical patients with OUD (9%) compared with only 3% higher for the overall sample. Consistent with existing evidence, 40 , 41 each categorical improvement in the quality of the nurse work environment was associated with improvements in all measured outcomes, although the analysis did not detect a stronger effect of the nurse work environment on postsurgical outcomes for patients with OUD versus those without. Our findings that nursing resources positively impact outcomes for surgical patients with OUD is consistent with a large body of existing evidence on samples of patients including those with Alzheimer’s disease and serious mental illness.…”

The effect of data aggregation on estimations of nurse staffing and patient outcomes

“…For example, several studies have reported that the unit work environment is associated with patient outcomes and with levels of nurse burnout. 33,34…”

Psychological responses of hospital-based nurses working during the COVID-19 pandemic in the United States: A cross-sectional study

“…Comprising the largest group of providers in hospitals, nurses have long been calling to improve their working conditions, including improving staffing and work environments to retain nurses and improve patient outcomes ( Brom, Brooks Carthon, Sloane, McHugh, & Aiken, 2021 ; Lasater et al, 2021 ). This has become more important now than ever ( Schlak, Aiken, Chittams, Poghosyan, & McHugh, 2021 ).…”
