Are minimum nurse-to-patient staffing ratios needed in hospitals? An observational study in British Columbia, Canada

Por: Lasater · K. B. · Brom · H. · Aiken · L. H. · McHugh · M. D.
Objective

To evaluate staffing conditions, patient outcomes, quality of care, patient safety and nurse job outcomes in British Columbia (BC), Canada hospitals.

Design

Cross-sectional study of 58 hospitals in BC with surveys of nurses and independent measures of patient outcomes.

Setting

58 hospitals in BC.

Participants

6685 hospital-based nurses working in a direct patient care role.

Exposures

Hospital-wide and unit-specific patient-to-nurse staffing ratios derived from registered nurse reports of how many patients and how many nurses were on their unit during their last shift worked.

Main outcomes and measures

Objective patient outcome measures included the Hospital Standardized Mortality Ratio (HSMR) and 30-day Readmission Rate, from 2022 to 2023 Canadian Institute for Health Information data. Nurses4All@BC provided data from 2024 using validated items on multiple measures (eg, nurse burnout, missed health breaks, intentions to leave, quality and safety measures such as culture of patient safety, quality of nursing care, missed nursing care).

Results

Burnout (59.4%), missed health breaks (41.7%), job dissatisfaction (36.0%), intentions to leave (19.3%) and patient outcomes (HSMR mean 95.4, median 96.0, range 26–180; readmission rate mean 10.0%, median 9.5%, range 7.9%–13.8%) were high and varied across hospitals. 68.3% of nurses reported there were not enough staff, and 77.3% reported their workloads were unsafe for patients. 60.6% of nurses gave their hospital an unfavourable patient safety rating. More patients per nurse were associated with poorer hospital mortality and readmission rates, poorer job outcomes for nurses, more adverse events for patients, less favourable ratings of quality of care and patient safety, more missed nursing care and poorer ratings of staffing adequacy and management.

Conclusions

Given the variability in staffing, quality and patient outcomes across BC hospitals, the implementation of a minimum nurse-to-patient ratio policy has the potential to improve patient care safety and retention of nurses.

Randomised waitlist-controlled trial of a 10-week community programme using a plant-based diet in a predominantly Maori population in Tairawhiti (Gisborne)

Por: Smith · M. · Wright · N. · McHugh · P. · Duncan · B. · Chwyl · C.
Objectives

Investigate the impact of a 10-week whole-food plant-based (WFPB) community programme on weight and type 2 diabetes up to 36 months postintervention.

Design

Randomised waitlist-controlled trial.

Setting

Community-based General Practice clinic classified as ‘Very Low-Cost Access’ in Gisborne, the main city of the Tairāwhiti region of New Zealand.

Participants

Adults (n=56) aged 30–72 years, with obesity (Body Mass Index (BMI) ≥30) and glycated haemoglobin (HbA1c≥40 mmol/mol) in the last 6 months. Of the participants, 59% identified as Māori and 5% as Pasifika.

Intervention

A 10-week programme consisting of 2 hours, two times per week sessions (40 hours total), involving skills-based learning and health education.

Primary and secondary outcome measures

Primary measures were changes in weight, BMI and HbA1c. Secondary measures included changes in cholesterol, waist circumference, exercise levels, plant-based and non-plant-based dietary scores and association with Big Five Inventory personality traits. The primary endpoint was assessed at post-treatment (10 weeks), with follow-up at 6 and 36 months postintervention.

Results

Differences between the intervention and waitlist control groups at 10 weeks were compared with independent samples t-tests. In intention-to-treat analyses, the intervention group demonstrated significantly greater weight loss of 3.3 kg (95% CI (0.8 to 5.7), pp values

Conclusions

This 10-week WFPB diet community intervention decreased weight, BMI, HbA1c and cholesterol. The intervention produced a weight loss of 5 kg post-treatment, with 3 kg weight loss sustained at 36 months.

Trial registration number

This trial was prospectively registered with the Australian New Zealand Clinical Trials Registry (https://anzctr.org.au); ACTRN12617000541303, date of registration 07/04/2017.

Effect of the Nurse Work Environment on Older Hispanic Surgical Patient Readmissions

imageBackground Readmissions following hospitalization for common surgical procedures are prevalent among older adults and are disproportionally experienced by Hispanic patients. One potential explanation for these disparities is that Hispanic patients may receive care in hospitals with lower-quality nursing care. Objectives The objective of this study was to evaluate the relationship between the hospital-level work environment of nurses and hospital readmissions among older Hispanic patients. Methods Using linked data sources from 2014 to 2016, we conducted a cross-sectional analysis of 522 hospitals and 732,035 general, orthopedic, and vascular surgical patients (80,978 Hispanic patients and 651,057 non-Hispanic White patients) in four states. Multivariable logistic regression models were employed to determine the relationship between the work environment and older Hispanic patient readmissions at multiple time periods (7, 30, and 90 days). Results In final adjusted models that included an interaction between work environment and ethnicity, an increase in the quality of the work environment resulted in a decrease in the odds of readmission that was greater for older Hispanic surgical patients at all time periods. Specifically, an increase in three of the five work environment subscales (Nurse Participation in Hospital Affairs, Nursing Foundations for Quality of Care, and Staffing and Resource Adequacy) was associated with a reduction in the odds of readmission that was greater for Hispanic patients than their non-Hispanic White counterparts. Discussion System-level investments in the work environment may reduce Hispanic patient readmission disparities. This study’s findings may be used to inform the development of targeted interventions to prevent hospital readmissions for Hispanic patients.
