Evaluating the Costs and Outcomes of Hospital Nursing Resources: a Matched Cohort Study of Patients with Common Medical Conditions

The Correctional Nursing Workforce Crisis: An Innovative Solution to Meet the Challenge

The aim of this article is to (1) review factors contributing to the nursing workforce crisis that also affect the specialty of correctional nursing and (2) describe an innovative programmatic approach to this crisis that includes translational strategies specific to recruitment and retention. A gap analysis led to a 4-phase framework identifying the career pathway for correctional nurses with a focus on recruitment and retention. The design of a correctional nurse recruitment and retention transition-to-practice program is the focus of the article and targets the preemployment phase of the framework. A correctional nurse expert panel reviewed and contributed to the structure and content of the program. Unique to this program is the content focus on professional identity in correctional nursing, which differs from professionalism.

Workload and short sickness absences in a cohort of Finnish hospital employees

This article used register data on day-to-day working hours of hospital employees combined with patient characteristics at work unit (wards) level to measure workload and its implications for short, self-certified sickness absences. We measured statistically the average nursing treatment burden of different patient mixes in hospital wards, and then analyzed the overall workload (intensity) of working days by comparing it to the actual available nursing workforce. We found that a significant part of the workload variation occurred between working days, and it was related to unexpected changes in the number of employees. In atypical situations a long work shift was associated with caring for patients with fewer resources. The high workload of a day increased the risk of short sickness absences along the following 3-week period. The results show that managing short-term workload variability should be a key aim from the perspective of well-being at work, and that combining different data sources can provide novel, important insights to the measurement of workload.

The Role of Structural Empowerment in Mediating the Relationship Between Practice Environment and Quality of Care Among Emergency Nurses: A Multilevel Modeling Approach

INTRODUCTION

Strong evidence demonstrated that working in a healthy environment has been associated with high-quality patient care. However, the mechanism underlying this relationship requires further investigation. This study aimed to examine the role of structural empowerment in mediating the relationship between nursing practice environment and quality of care among emergency nurses.

METHODS

A proportional stratified clustered sampling technique was used to recruit staff nurses working in acute care hospitals in Oman. Four standardized instruments were used to assess nurses' sociodemographic characteristics, perception of the practice environment, structural empowerment, and perceived quality of care. Hayes' process for mediation analysis was used to examine whether empowerment mediates the relationship between the practice environment and quality of care.

RESULTS

A total of 160 emergency nurses participated. The majority (78.8%) perceived the quality of care as good/excellent. Having an adequate foundation for quality of care, sufficient staffing, and managerial support were significant predictors of perceived quality of care. Practice environment was directly and indirectly related to the perceived quality of care through structural empowerment.

DISCUSSION

Nurse leaders can enhance care quality in emergency departments by improving the work environment through engaging nurses in quality activities, ensuring adequate staffing and resources, and providing robust leadership support, which collectively empower nurses and improve patient outcomes.

«I can't imagine it without my nurse»: Experiences of people with chronic kidney disease in the evaluation process as kidney transplant candidates

This qualitative study aimed to explore the experiences of 11 adults with chronic kidney disease (CKD) undergoing evaluation for kidney transplant (KT) and examine the role played by the nurse in the process. Employing a descriptive phenomenology approach, semi-structured interviews were conducted between October 2022 and July 2023. Thematic analysis, facilitated by Atlas. ti software, revealed a systemic management diagram with "The candidate for kidney transplant and their reality" at the center, followed by "The process of chronic kidney disease and kidney transplantation," and concluding with the most distal category centered on "The kidney transplant access nurse." This organizational framework provided insights into the layers of relationships between emerging themes. The findings underscored the complexity and multidimensionality of the CKD and KT process, emphasizing the nurse's pivotal role as a guide and protector throughout the evaluation process for accessing kidney transplantation. The convergence of results with existing literature highlighted the need to address challenges such as lack of time, resources, and emotional support to enhance the quality of care. Recognizing the nurse's crucial importance in this process, the study emphasizes the significance of addressing these challenges to improve patient care and calls for attention to the nurse's role in guiding individuals through the intricate journey of CKD and kidney transplantation.

The Nursing Human Capital Value Model

Nursing's economic value is presently framed within the dominant "outcomes-over-cost" value framework. Within this context, organizations employing nurses often use nursing budget reductions as a cost-minimization strategy, with the intent of retaining high quality outcomes. However, persistent issues such as nurse understaffing, burnout, and turnover threaten healthcare systems' capacity to deliver the quality, equitable, affordable patient care that the public requires. In this paper, we propose a new conceptual model and definition of nursing's economic value. The model development is guided by the convergence of three classic economic frameworks: human capital theory, production theory, and value theory. Grounded in these theories, we envision nursing as a value-adding human capital asset and explicitly link nursing staff characteristics and allocation to the production of healthcare services and organizational financial outcomes. We redefine nursing's economic value as the return on investment (ROI) in nursing human capital reflected in the improvement of consumer, nurse, and organizational outcomes. This new conceptual model, termed the Nursing Human Capital Value Model, presents a cycle of value creation that starts with investments in growing, developing and sustaining an organization's nursing human capital. Nurses, as a human capital asset, deliver nursing care-a foundational ingredient to the production of healthcare services and consumer outcomes. Improved outcomes, subsequently, drive organizational revenue growth. Finally, the accrued revenue is reinvested in nursing, further propelling the cycle's continuation. This innovative model, which is applicable across health systems financed through both governmental and private/non-governmental payor sources, highlights that investment in nursing human capital development is essential for sustainable value generation, identifying opportunities for optimizing nurses' contributions to the value cycle. By directly incorporating economic theories of human capital, production, and value, our model paves the way for future research on the dynamic scope of nursing's economic contribution within healthcare organizations and systems and underscores its necessity for the long-term sustainability and growth of the nursing profession.

Hospital nurse staffing variation and Covid-19 deaths: A cross-sectional study

BACKGROUND

During the Covid-19 pandemic, Covid-19 mortality varied depending on the hospital where patients were admitted, but it is unknown what aspects of hospitals were important for mitigating preventable deaths.

OBJECTIVE

To determine whether hospital differences in pre-pandemic and during pandemic nursing resources-average patient-to-registered nurse (RN) staffing ratios, proportion of bachelor-qualified RNs, nurse work environments, Magnet recognition-explain differences in risk-adjusted Covid-19 mortality; and to estimate how many deaths may have been prevented if nurses were better resourced prior to and during the pandemic.

METHODS

This is a cross-sectional study of 87,936 Medicare beneficiaries (65-99 years old) hospitalized with Covid-19 and discharged (or died) between April 1 and December 31, 2020, in 237 general acute care hospitals in New York and Illinois. Measures of hospital nursing resources (i.e. patient-to-RN staffing ratios, proportion of bachelor-qualified RNs, nurse work environments, Magnet recognition) in the pre-pandemic period (December 2019 to February 2020) and during (April to June 2021) were used to predict in-hospital and 30-day mortality using adjusted logistic regression models.

RESULTS

The mean age of patients was 78 years (8.6 SD); 51 % were male (n = 44,998). 23 % of patients admitted to the hospital with Covid-19 died during the hospitalization (n = 20,243); 31.5 % died within 30-days of admission (n = 27,719). Patients admitted with Covid-19 to hospitals with better nursing resources pre-pandemic and during the pandemic were statistically significantly less likely to die. For example, each additional patient in the average nurses' workload pre-pandemic was associated with 20 % higher odds of in-hospital mortality (OR 1.20, 95 % CI [1.12-1.28], p < 0.001) and 15 % higher odds of 30-day mortality (OR 1.15, 95 % CI [1.09-1.21], p < 0.001). Hospitals with greater proportions of BSN-qualified RNs, better quality nurse work environments, and Magnet recognition offered similar protective benefits to patients during the pandemic. If all hospitals in the study had superior nursing resources prior to or during the pandemic, models estimate many thousands of deaths among patients hospitalized with Covid-19 could have been avoided.

CONCLUSIONS

Patients with Covid-19 admitted to hospitals with adequate numbers of RNs caring for patients, a workforce rich in BSN-qualified RNs, and high-quality nurse work environments (both prior to and during the Covid-19 pandemic) were more likely to survive the hospitalization. Bolstering these hospital nursing resources during ordinary times is necessary to ensure better patient outcomes and emergency-preparedness of hospitals for future public health emergencies.

Choice of needleless connector technology as a risk reduction strategy for catheter related bloodstream infection, mortality, and cost: A secondary data analysis

OBJECTIVE

To compare relative risk (RR) of central line-associated bloodstream infection (CLABSI) between hospitals using Clave needleless connector technologies (NCT) and comparator hospitals using non-Clave NCT. And, to estimate avoided CLABSIs, mortality, and cost savings.

BACKGROUND

Needleless connectors, while protective against needlestick injury, have long been implicated as a potential risk for CLABSI. Significant RR reduction of CLABSI among the many NCT has not been clinically demonstrated.

METHODS

The U.S. Healthcare-Associated Infections database was accessed for CLABSI data for calendar year 2019 via the Centers for Medicare and Medicaid Services website. This dataset was merged with the Clave NCT manufacturer's 2019 database to identify hospitals purchasing Clave NCT (MicroClave™, NanoClave™, Clave Neutron™, Clave™, Microclave™ Clear) and non-Clave NCT comparator hospitals. Sub-analysis of Clave NCT hospitals included: (1) Clave NCT mixed-use and (2) Clave high-volume use hospitals. The standardized infection ratio (SIR) was generated to estimate CLABSI RR after adjusting for intern/resident-to-bed-ratio (IRB), care location, and hospital demographics. Using the RR, avoided CLABSIs, mortality, and cost savings were calculated.

RESULTS

A total of 2987 eligible hospitals (1288 Clave NCT, 1699 non-Clave NCT) with 17,452,575 central line-days were evaluated. All three Clave NCT hospital groups showed a statistically significant reduction in RR compared to the non-Clave NCT hospitals. The RR in Clave NCT hospitals was 0.93, a 7% decrease in CLABSI risk (p = 0.02). In the Clave NCT subgroups, mixed-use hospitals RR was 0.93, a 7% reduction (p = 0.04), while the Clave NCT high-volume hospitals experienced a 19% reduction, RR 0.81 (p = 0.04). An estimated 563 CLABSIs and 84 related deaths were avoided with use of Clave NCT and $27,095,231 in cost savings.

CONCLUSION

The use of the Clave NCT, in and of itself, is an effective risk reduction strategy for CLABSI prevention, reduced mortality, and substantial cost savings.

Associations of the staffing structure of intensive care units and high care units on in-hospital mortality among patients with sepsis: a cross-sectional study of Japanese nationwide claims data

OBJECTIVE

The objective was to analyse the associations of intensive care unit (ICU) and high care unit (HCU) organisational structure on in-hospital mortality among patients with sepsis in Japan's acute care hospitals.

DESIGN

Multicentre cross-sectional study.

SETTINGS

Patients with sepsis aged ≥18 years who received critical care in acute care hospitals throughout Japan between April 2018 and March 2019 were identified using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB).

INTERVENTIONS

None.

PARTICIPANTS

10 968 patients with sepsis were identified. ICUs were categorised into three groups: type 1 ICUs (fulfilling stringent staffing criteria such as experienced intensivists and high nurse-to-patient ratios), type 2 ICUs (less stringent criteria) and HCUs (least stringent criteria).

PRIMARY OUTCOME MEASURE

The study's primary outcome measure was in-hospital mortality. Cox proportional hazards regression analysis was performed to examine the impact of ICU/HCU groups on in-hospital mortality.

RESULTS

We analysed 2411 patients (178 hospitals) in the type 1 ICU group, 3653 patients (422 hospitals) in the type 2 ICU group and 4904 patients (521 hospitals) in the HCU group. When compared with the type 1 ICU group, the adjusted HRs for in-hospital mortality were 1.12 (95% CI 1.04 to 1.21) for the type 2 ICU group and 1.17 (95% CI 1.08 to 1.26) for the HCU group.

CONCLUSION

ICUs that fulfil more stringent staffing criteria were associated with lower in-hospital mortality among patients with sepsis than HCUs. Differences in organisational structure may have an association with outcomes in patients with sepsis, and this was observed by the NDB.

Relationship between mental workload and musculoskeletal disorders with intention to leave service among nurses working at neonatal and pediatric departments: a cross-sectional study in Iran

BACKGROUND

Despite the challenge of nursing shortage in the world and its subsequent impact on care quality as well as aggravation of the situation by intention to leave service, this issue has not been properly addressed, especially among neonatal and pediatric nurses. The present study aims to identify the relationship between mental workload and musculoskeletal disorders with intention to leave the service among nurses working at neonatal and pediatric departments.

METHODS

This descriptive-analytical study was conducted on 145 nurses working at neonatal and pediatric departments in six hospitals in Bushehr Province using full-census method. The data were collected using national aeronautics and space administration-task load index (NASA-TLX), Cornell musculoskeletal discomfort questionnaire(CMDQ) and Mobley and Horner's voluntary turnover questionnaire. The data were analyzed using descriptive statistics, independent t-test, Mann-Whitney U test, one-way analysis of variance (ANOVA), Kruskal-Wallis test, Pearson's and Spearman correlation tests and hierarchical linear regression in simultaneous model in SPSS 19.0.

RESULTS

The mean score of intention to leave the service was 9.57 ± 3.20 (higher than the moderate level) and the mean mental workload was 71.65 ± 15.14 (high level). Pain in at least one of the legs (100%), back (77.3%) and knees (76.6%) was highly prevalent. However, no statistically significant correlation was found between musculoskeletal disorder categories and intention to leave the service (p > 0.05). The regression analysis results revealed among mental workload domains, only effort-induced workload was negatively and significantly correlated with intention to leave the service (p = 0.003; β=-0.078). However, the number of night shifts per month was positively and significantly correlated with intention to leave the service (p = 0.001; β = 0.176).

CONCLUSIONS

Planning for appropriate allocation of night shifts, investigating the etiology of musculoskeletal disorders and providing solutions for reducing mental workload should be prioritized by policymakers, while maintaining pediatric nurses' motivation for making efforts.

Emergent Penile Venous Stripping for Treating Adolescent Impotence

INTRODUCTION

Traditional anatomy-based penile venous surgery is deemed inadequate. Based on revolutionary insights into penile vasculature, penile venous stripping (PVS) shows promise in treating adolescent erectile dysfunction (AED). We aimed to report on this novel approach.

METHODS

We conducted a retrospective analysis of 223 individuals under 30 diagnosed with veno-occlusive dysfunction (VOD) between 2009 and 2023. Among them, 83 were diagnosed with AED and divided into the PVS (n = 37) and no-surgery (NS, n = 46) groups. All participants had been dissatisfied with conventional therapeutic options. Dual pharmaco-cavernosography was the primary diagnostic modality. PVS involved stripping the deep dorsal vein and two cavernosal veins after securing each emissary's vein with a 6-0 nylon suture. Erection restoration was accessed using the abridged five-item version of the International Index of Erectile Function (IIEF-5) score system and the erection hardness scale (EHS). Statistical analysis was performed using IBM SPSS 21.0.

RESULTS

There were significant differences (both p < 0.001) between the preoperative and postoperative IIEF-5 scores in the PVS and NS groups (9.8 ± 3.0 vs. 20.4 ± 2.2; 9.9 ± 2.5 vs. 9.5 ± 2.1), as well as in the EHS scores (1.7 ± 0.7 vs. 3.5 ± 0.6 and 1.8 ± 0.5 vs. 1.3 ± 0.4). The satisfaction rate was 87.9% (29/33) in the PVS group and 16.7% (17/41) in the NS group.

CONCLUSIONS

AED can be effectively treated using physiological methods, although larger patient cohorts are needed for validation.

Hospital Performance on Hospital Consumer Assessment of Healthcare Providers and System Ratings: Associations With Nursing Factors

OBJECTIVE

To determine which hospital nursing resources (staffing, skill mix, nurse education, and nurse work environment) are most predictive of hospital Hospital Consumer Assessment of Healthcare Providers and System (HCAHPS) performance.

BACKGROUND

HCAHPS surveying is designed to quantify patient experience, a measure of patient-centered care. Hospitals are financially incentivized through the Centers for Medicare and Medicaid Services to achieve high HCAHPS ratings, but little is known about what modifiable hospital factors are associated with higher HCAHPS ratings.

PATIENTS AND METHODS

Secondary analysis of multiple linked data sources in 2016 providing information on hospital HCAHPS ratings, hospital nursing resources, and other hospital attributes (eg, size, teaching, and technology status). Five hundred forty non-federal adult acute care hospitals in California, Florida, New Jersey, and Pennsylvania, and 11,786 registered nurses working in those hospitals. Predictor variables included staffing (ie, patient-to-nurse ratio), skill mix (ie, the proportion of registered nurses to all nursing staff), nurse education (ie, percentage of nurses with a bachelor's degree or higher), and nurse work environment (ie, the quality of the environment in which nurses work). HCAHPS ratings were the outcome variable.

RESULTS

More favorable staffing, higher proportions of bachelor-educated nurses, and better work environments were associated with higher HCAHPS ratings. The work environment had the largest association with higher HCAHPS ratings, followed by nurse education, and then staffing. Superior staffing and work environments were associated with higher odds of a hospital being a "higher HCAHPS performer" compared with peer hospitals.

CONCLUSION

Improving nursing resources is a strategic organizational intervention likely to improve HCAHPS ratings.

Impact of Hospital Affiliation With a Flagship Hospital System on Surgical Outcomes

OBJECTIVE

To compare general surgery outcomes at flagship systems, flagship hospitals, and flagship hospital affiliates versus matched controls.

SUMMARY BACKGROUND DATA

It is unknown whether flagship hospitals perform better than flagship hospital affiliates for surgical patients.

METHODS

Using Medicare claims for 2018 to 2019, we matched patients undergoing inpatient general surgery in flagship system hospitals to controls who underwent the same procedure at hospitals outside the system but within the same region. We defined a "flagship hospital" within each region as the major teaching hospital with the highest patient volume that is also part of a hospital system; its system was labeled a "flagship system." We performed 4 main comparisons: patients treated at any flagship system hospital versus hospitals outside the flagship system; flagship hospitals versus hospitals outside the flagship system; flagship hospital affiliates versus hospitals outside the flagship system; and flagship hospitals versus affiliate hospitals. Our primary outcome was 30-day mortality.

RESULTS

We formed 32,228 closely matched pairs across 35 regions. Patients at flagship system hospitals (32,228 pairs) had lower 30-day mortality than matched control patients [3.79% vs. 4.36%, difference=-0.57% (-0.86%, -0.28%), P<0.001]. Similarly, patients at flagship hospitals (15,571/32,228 pairs) had lower mortality than control patients. However, patients at flagship hospital affiliates (16,657/32,228 pairs) had similar mortality to matched controls. Flagship hospitals had lower mortality than affiliate hospitals [difference-in-differences=-1.05% (-1.62%, -0.47%), P<0.001].

CONCLUSIONS

Patients treated at flagship hospitals had significantly lower mortality rates than those treated at flagship hospital affiliates. Hence, flagship system affiliation does not alone imply better surgical outcomes.

Mortality Among the Dementia Population in Not-For-Profit Hospitals with Better Nursing Resources

The dementia population has higher rates of mortality during hospital stays than those without dementia. The aim of this study is to examine the relationship between ownership status (i.e. for-profit vs. not-for-profit) and nursing resources (i.e. nurse work environment, nurse-to-patient staffing, and nurse education) on 30-day mortality among post-surgical older adults with dementia. A cross-sectional analysis of linked American Hospital Association, Medicare claims, and nurse survey data was conducted using multi-level logistic regression models. We examined these models to assess the relationship between ownership status and 30-day mortality after adjusting patient and hospital characteristics. We also analyzed the relationship between the hospital ownership status and the 30-day mortality, after considering the three nursing resources. Older adults with dementia who received care in hospitals with not-for-profit status were less likely to die within 30 days of admission following surgery compared to those treated in hospitals with for-profit hospital status (i.e. odds ratio 0.82, 95% confidence interval 0.73-0.92, p = <.001). In addition, the odds ratios estimating the association between ownership and mortality were similar across the different models of the three nursing resources with and without those controls (i.e. 0.88 vs. 0.83 vs. 0.82). Surgical patients with dementia had better outcomes when cared for in not-for-profit hospitals, particularly with greater levels of nurse education and nurse staffing. The relationship between profit status and mortality was partly explained by the lower levels of nurse staffing and education in for-profit vs. not-for-profit hospitals.

A Review of Disparities in Outcomes of Hospitalized Patients with Limited English Proficiency: The Importance of Nursing Resources

Language barriers significantly affect communication between patients and health care staff and are associated with receipt of lower-quality care. Registered nurses are well positioned members of the health care team to reduce and eliminate disparities for patients with limited English proficiency (LEP). Current evidence recommends nurses use interpreters or translation devices to overcome language barriers; however, these recommendations fail to recognize that structural system-level factors, such as unsupportive work environments and poor nurse-to-patient staffing ratios, reduce nurses' ability to implement these recommendations. The Quality Health Outcomes Model (QHOM) is a useful framework for understanding relationships between hospital systems, the delivery of care interventions, and patient outcomes. The goal of this manuscript is to use the QHOM and existing empirical evidence to present a new perspective on the long-standing clinical challenge of reducing language-related health outcome disparities by considering the context in which nurses deliver patient care.

'Thank goodness you're here'. Exploring the impact on patients, family carers and staff of enhanced 7-day specialist palliative care services: A mixed methods study

BACKGROUND

Healthcare usage patterns change for people with life limiting illness as death approaches, with increasing use of out-of-hours services. How best to provide care out of hours is unclear.

AIM

To evaluate the effectiveness and effect of enhancements to 7-day specialist palliative care services, and to explore a range of perspectives on these enhanced services.

DESIGN

An exploratory longitudinal mixed-methods convergent design. This incorporated a quasi-experimental uncontrolled pre-post study using routine data, followed by semi-structured interviews with patients, family carers and health care professionals.

SETTING/PARTICIPANTS

Data were collected within specialist palliative care services across two UK localities between 2018 and 2020. Routine data from 5601 unique individuals were analysed, with post-intervention interview data from patients (n = 19), family carers (n = 23) and health care professionals (n = 33; n = 33 time 1, n = 20 time 2).

RESULTS

The mean age of people receiving care was 73 years, predominantly white (90%) and with cancer (42%). There were trends for those in the intervention (enhanced care) period to stay in hospital 0.16 days fewer, but be hospitalised 2.67 more times. Females stayed almost 3.5 more days in the hospital, but were admitted 2.48 fewer times. People with cancer had shorter hospitalisations (4 days fewer), and had two fewer admission episodes. Themes from the qualitative data included responsiveness (of the service); reassurance; relationships; reciprocity (between patients, family carers and staff) and retention (of service staff).

CONCLUSIONS

Enhanced seven-day services provide high quality integrated palliative care, with positive experiences for patients, carers and staff.

The Relationship Between Scope of Practice Laws for Task Delegation and Nurse Turnover in Home Health

OBJECTIVE

Nurse turnover can compromise the quality and continuity of home health care. Scope of practice laws, which determine the tasks nurses are allowed to perform and delegate, are an important element of autonomy and vary across states. In this study, we used human resource records from a multistate home health organization to examine the relationship between nurse turnover and whether nurses can delegate tasks to unlicensed aides.

DESIGN

A retrospective, cross-sectional analysis.

SETTING AND PARTICIPANTS

The study sample included 1820 licensed practical nurses and 3309 registered nurses, who spanned 30 states. The study period was 2016 through 2018.

METHODS

We used weighted least squares to study the relationship between nurse turnover for registered and licensed practical nurses and task delegation across state-years. We measured task delegation continuously (0-16 tasks) and as a binary variable (14 or more tasks, which indicated the state was in the top half of the distribution).

RESULTS

Across state-years, the turnover rate was 30.8% for licensed practical nurses and 36.8% for registered nurses. Although there was no significant relationship between task delegation and turnover among registered nurses, we found that states in which nurses could delegate the most tasks had lower turnover rates among licensed practical nurses.

CONCLUSION AND IMPLICATIONS

The ability to delegate tasks to unlicensed aides was correlated with lower turnover rates among licensed practical nurses, but not among registered nurses. This suggests that the ability to delegate tasks is more likely to affect the workload of licensed practical nurses. This also points to a potential and unexplored element of expanding the scope of practice for nurses: reduced turnover. Given the added work-related hazards associated with home health care, including working in isolation, a lack of social recognition, and inadequate reimbursement, states should consider whether changes in their policy environment could benefit nurses working in home health.

Costs and cost-effectiveness of improved nurse staffing levels and skill mix in acute hospitals: A systematic review

BACKGROUND

Extensive research shows associations between increased nurse staffing levels, skill mix and patient outcomes. However, showing that improved staffing levels are linked to improved outcomes is not sufficient to provide a case for increasing them. This review of economic studies in acute hospitals aims to identify costs and consequences associated with different nurse staffing configurations in hospitals.

METHODS

We included economic studies exploring the effect of variation in nurse staffing. We searched PubMed, CINAHL, Embase Econlit, Cochrane library, DARE, NHS EED and the INAHTA website. Risk of bias was assessed using a framework based on the NICE guidance for public health reviews and Henrikson's framework for economic evaluations. Inclusion, data extraction and critical appraisal were undertaken by pairs of reviewers with disagreements resolved by the entire review team. Results were synthesised using a hierarchical matrix to summarise findings of economic evaluations.

RESULTS

We found 23 observational studies conducted in the United States of America (16), Australia, Belgium, China, South Korea, and the United Kingdom (3). Fourteen had high risk of bias and nine moderate. Most studies addressed levels of staffing by RNs and/or licensed practical nurses. Six studies found that increased nurse staffing levels were associated with improved outcomes and reduced or unchanged net costs, but most showed increased costs and outcomes. Studies undertaken outside the USA showed that increased nurse staffing was likely to be cost-effective at a per capita gross domestic product (GDP) threshold or lower. Four studies found that increased skill mix was associated with improved outcomes but increased staff costs. Three studies considering net costs found increased registered nurse skill mix associated with net savings and similar or improved outcomes.

CONCLUSION

Although more evidence on cost-effectiveness is still needed, increases in absolute or relative numbers of registered nurses in general medical and surgical wards have the potential to be highly cost-effective. The preponderance of the evidence suggests that increasing the proportion of registered nurses is associated with improved outcomes and, potentially, reduced net cost. Conversely, policies that lead to a reduction in the proportion of registered nurses in nursing teams could give worse outcomes at increased costs and there is no evidence that such approaches are cost-effective. In an era of registered nurse scarcity, these results favour investment in registered nurse supply as opposed to using lesser qualified staff as substitutes, especially where baseline nurse staffing and skill mix are low.

REGISTRATION

PROSPERO (CRD42021281202).

TWEETABLE ABSTRACT

Increasing registered nurse staffing and skill mix can be a net cost-saving solution to nurse shortages. Contrary to the strong policy push towards a dilution of nursing skill mix, investment in supply of RNs should become the priority.

Cost comparisons and factors related to cost per stay in intensive care units in Belgium

BACKGROUND

Given the variability of intensive care unit (ICU) costs in different countries and the importance of this information for guiding clinicians to effective treatment and to the organisation of ICUs at the national level, it is of value to gather data on this topic for analysis at the national level in Belgium. The objectives of the study were to assess the total cost of ICUs and the factors that influence the cost of ICUs in hospitals in Belgium.

METHODS

This was a retrospective cohort study using data collected from the ICUs of 17 Belgian hospitals from January 01 to December 31, 2018. A total of 18,235 adult ICU stays were included in the study. The data set was a compilation of inpatient information from analytical cost accounting of hospitals, medical discharge summaries, and length of stay data. The costs were evaluated as the expenses related to the management of hospital stays from the hospital's point of view. The cost from the hospital perspective was calculated using a cost accounting analytical methodology in full costing. We used multivariate linear regression to evaluate factors associated with total ICU cost per stay. The ICU cost was log-transformed before regression and geometric mean ratios (GMRs) were estimated for each factor.

RESULTS

The proportion of ICU beds to ward beds was a median [p25-p75] of 4.7% [4.4-5.9]. The proportion of indirect costs to total costs in the ICU was 12.1% [11.4-13.3]. The cost of nurses represented 57.2% [55.4-62.2] of direct costs and this was 15.9% [12.0-18.2] of the cost of nurses in the whole hospital. The median cost per stay was €4,267 [2,050-9,658] and was €2,160 [1,545-3,221] per ICU day. The main factors associated with higher cost per stay in ICU were Charlson score, mechanical ventilation, ECMO, continuous hemofiltration, length of stay, readmission, ICU mortality, hospitalisation in an academic hospital, and diagnosis of coma/convulsions or intoxication.

CONCLUSIONS

This study demonstrated that, despite the small proportion of ICU beds in relation to all services, the ICU represented a significant cost to the hospital. In addition, this study confirms that nursing staff represent a significant proportion of the direct costs of the ICU. Finally, the total cost per stay was also important but highly variable depending on the medical factors identified in our results.

A comparison of critical access hospitals and other rural acute care hospitals in Pennsylvania

PURPOSE

As the Flex Program celebrates its 25th anniversary, we examined changes in critical access hospital (CAH) financial performance, investigated whether CAH status has reduced hospitals' financial vulnerability, and identified factors influencing financial performance.

METHODS

We collected data on acute care hospitals in Pennsylvania's rural counties for 2000-20. Our sample contained 1,444 hospital-year observations. We used trend analysis to compare the financial performance of CAHs and rural prospective payment system (PPS) hospitals (non-CAHs). We investigated the effect of CAH status on financial performance and identified the time-variant factors impacting financial performance using fixed-effects regression analysis.

RESULTS

The median total margin of CAHs lagged behind that of non-CAHs. When compared to non-CAH costs over the same period, the median cost per patient day incurred by CAHs has increased, with the rate of increase being significantly higher in the most recent decade. Our findings show that while CAH status does not appear to have a direct impact on the total margin, it is significantly associated with a higher cost per patient day.

CONCLUSIONS

CAHs in Pennsylvania appear to be facing a double whammy of declining margins and rising costs compared to non-CAHs. Our findings demonstrate how crucial the Flex program has been in sustaining CAHs in Pennsylvania ever since its inception. Our findings have implications for rural health care delivery as well. While providing financial support and operational flexibility to CAHs should be a continuing policy priority, a long-term policy goal should be to envision an economic development strategy that capitalizes on the unique strengths of each of the rural archetypes.

Patient Outcomes and Hospital Nurses’ Workload: A Cross-Sectional Observational Study in Slovenian Hospitals Using the RN4CAST Survey

Introduction

Higher nursing workload increases the odds of patient deaths, as the work environment has a significant effect on patient outcomes. The aim of the study was to explore the relation between patient outcomes and nurses’ working conditions in hospitals.

Methods

Administrative data on discharges of surgical patients for the year 2019 in eight general hospitals and two university medical centres in Slovenia were collected to determine in-hospital mortality within 30 days of admission. The RN4CAST survey questionnaire was used to gather data from nurses in these hospitals, with 1,010 nurses participating. Data was collected at the beginning of 2020. The number of nurses per shift and the nurse-to-patient ratio per shift were calculated. Univariate, bivariate and multivariate statistical methods were used to analyse the data.

Results

The 30-day in-hospital mortality for surgical patients was 1.00% in the hospitals sampled and ranged from 0.27% to 1.62%. The odds ratio for staffing suggests that each increase of one patient per RN is associated with a 6% increase in the likelihood of a patient dying within 30 days of admission. The mean patient-to-RN ratio was 15.56 (SD=2.50) and varied from 10.29 to 19.39. Four of the 13 tasks checked were not performed on patients during the last shift.

Conclusion

The results are not encouraging, with an extremely critical shortage of RNs and thus a high RN workload. The number of patients per RN is the highest in Europe and also higher than in some non-European countries, and represents an extreme risk to the quality of nursing and healthcare as a whole. The recommendation for acute non-emergency internal medicine and surgery departments is four patients per RN per shift.

Explaining racial disparities in surgical survival: a tapered match analysis of patient and hospital factors

OBJECTIVES

Evaluate whether hospital factors, including nurse resources, explain racial differences in Medicare black and white patient surgical outcomes and whether disparities changed over time.

DESIGN

Retrospective tapered-match.

SETTING

571 hospitals at two time points (Early Era 2003-2005; Recent Era 2013-2015).

PARTICIPANTS

6752 black patients and three sets of 6752 white controls selected from 107 001 potential controls (Early Era). 4964 black patients and three sets of 4964 white controls selected from 74 108 potential controls (Recent Era).

INTERVENTIONS

Black patients were matched to white controls on demographics (age, sex, state and year of procedure), procedure (demographics variables plus 136 International Classification of Diseases (ICD)-9 principal procedure codes) and presentation (demographics and procedure variables plus 34 comorbidities, a mortality risk score, a propensity score for being black, emergency admission, transfer status, predicted procedure time).

OUTCOMES

30-day and 1-year mortality.

RESULTS

Before matching, black patients had more comorbidities, higher risk of mortality despite being younger and underwent procedures at different percentages than white patients. Whites in the demographics match had lower mortality at 30 days (5.6% vs 6.7% Early Era; 5.4% vs 5.7% Recent Era) and 1-year (15.5% vs 21.5% Early Era; 12.3% vs 15.9% Recent Era). Black-white 1-year mortality differences were equivalent after matching patients with respect to presentation, procedure and demographic factors. Black-white 30-day mortality differences were equivalent after matching on procedure and demographic factors. Racial disparities in outcomes remained unchanged between the two time periods spanning 10 years. All patients in hospitals with better nurse resources had lower odds of 30-day (OR 0.60, 95% CI 0.46 to 0.78, p<0.010) and 1-year mortality (OR 0.77, 95% CI 0.65 to 0.92, p<0.010) even after accounting for other hospital factors.

CONCLUSIONS

Survival disparities among black and white patients are largely explained by differences in demographic, procedure and presentation factors. Better nurse resources (eg, staffing, work environment) were associated with lower mortality for all patients.

Defining Multimorbidity in Older Patients Hospitalized with Medical Conditions

BACKGROUND

The term "multimorbidity" identifies high-risk, complex patients and is conventionally defined as ≥2 comorbidities. However, this labels almost all older patients as multimorbid, making this definition less useful for physicians, hospitals, and policymakers.

OBJECTIVE

Develop new medical condition-specific multimorbidity definitions for patients admitted with acute myocardial infarction (AMI), heart failure (HF), and pneumonia patients. We developed three medical condition-specific multimorbidity definitions as the presence of single, double, or triple combinations of comorbidities - called Qualifying Comorbidity Sets (QCSs) - associated with at least doubling the risk of 30-day mortality for AMI and pneumonia, or one-and-a-half times for HF patients, compared to typical patients with these conditions.

DESIGN

Cohort-based matching study PARTICIPANTS: One hundred percent Medicare Fee-for-Service beneficiaries with inpatient admissions between 2016 and 2019 for AMI, HF, and pneumonia.

MAIN MEASURES

Thirty-day all-location mortality KEY RESULTS: We defined multimorbidity as the presence of ≥1 QCS. The new definitions labeled fewer patients as multimorbid with a much higher risk of death compared to the conventional definition (≥2 comorbidities). The proportions of patients labeled as multimorbid using the new definition versus the conventional definition were: for AMI 47% versus 87% (p value<0.0001), HF 53% versus 98% (p value<0.0001), and pneumonia 57% versus 91% (p value<0.0001). Thirty-day mortality was higher among patients with ≥1 QCS compared to ≥2 comorbidities: for AMI 15.0% versus 9.5% (p<0.0001), HF 9.9% versus 7.0% (p <0.0001), and pneumonia 18.4% versus 13.2% (p <0.0001).

CONCLUSION

The presence of ≥2 comorbidities identified almost all patients as multimorbid. In contrast, our new QCS-based definitions selected more specific combinations of comorbidities associated with substantial excess risk in older patients admitted for AMI, HF, and pneumonia. Thus, our new definitions offer a better approach to identifying multimorbid patients, allowing physicians, hospitals, and policymakers to more effectively use such information to consider focused interventions for these vulnerable patients.

Redefining Multimorbidity in Older Surgical Patients

BACKGROUND

Multimorbidity in surgery is common and associated with worse postoperative outcomes. However, conventional multimorbidity definitions (≥2 comorbidities) label the vast majority of older patients as multimorbid, limiting clinical usefulness. We sought to develop and validate better surgical specialty-specific multimorbidity definitions based on distinct comorbidity combinations.

STUDY DESIGN

We used Medicare claims for patients aged 66 to 90 years undergoing inpatient general, orthopaedic, or vascular surgery. Using 2016 to 2017 data, we identified all comorbidity combinations associated with at least 2-fold (general/orthopaedic) or 1.5-fold (vascular) greater risk of 30-day mortality compared with the overall population undergoing the same procedure; we called these combinations qualifying comorbidity sets. We applied them to 2018 to 2019 data (general = 230,410 patients, orthopaedic = 778,131 patients, vascular = 146,570 patients) to obtain 30-day mortality estimates. For further validation, we tested whether multimorbidity status was associated with differential outcomes for patients at better-resourced (based on nursing skill-mix, surgical volume, teaching status) hospitals vs all other hospitals using multivariate matching.

RESULTS

Compared with conventional multimorbidity definitions, the new definitions labeled far fewer patients as multimorbid: general = 85.0% (conventional) vs 55.9% (new) (p < 0.0001); orthopaedic = 66.6% vs 40.2% (p < 0.0001); and vascular = 96.2% vs 52.7% (p < 0.0001). Thirty-day mortality was higher by the new definitions: general = 3.96% (conventional) vs 5.64% (new) (p < 0.0001); orthopaedic = 0.13% vs 1.68% (p < 0.0001); and vascular = 4.43% vs 7.00% (p < 0.0001). Better-resourced hospitals offered significantly larger mortality benefits than all other hospitals for multimorbid vs nonmultimorbid general and orthopaedic, but not vascular, patients (general surgery difference-in-difference = -0.94% [-1.36%, -0.52%], p < 0.0001; orthopaedic = -0.20% [-0.34%, -0.05%], p = 0.0087; and vascular = -0.12% [-0.69%, 0.45%], p = 0.6795).

CONCLUSIONS

Our new multimorbidity definitions identified far more specific, higher-risk pools of patients than conventional definitions, potentially aiding clinical decision-making.

The NUTRIC Score as a Tool to Predict Mortality and Increased Resource Utilization in Intensive Care Patients with Sepsis

The Nutrition Risk in Critically Ill score (NUTRIC) is an important nutritional risk assessment instrument for patients in the intensive care unit (ICU). The purpose of this study was to evaluate the power of the score to predict mortality in patients treated for sepsis and to forecast increased resource utilization and nursing workload in the ICU. The NUTRIC score predicted mortality (AUC 0.833, p < 0.001) with the optimal cut-off value of 6 points. Among patients with a score ≥ 6 on ICU admission, the 28-day mortality was 61%, and 10% with a score < 6 (p < 0.001). In addition, a NUTRIC score of ≥6 was associated with a more intense use of ICU resources, as evidenced by a higher proportion of patients requiring vasopressor infusion (98 vs. 82%), mechanical ventilation (99 vs. 87%), renal replacement therapy (54 vs. 26%), steroids (68 vs. 31%), and blood products (60 vs. 43%); the nursing workload was also significantly higher in this group. In conclusion, the NUTRIC score obtained at admission to the ICU provided a good discriminative value for mortality and makes it possible to identify patients who will ultimately require intense use of ICU resources and an associated increase in the nursing workload during treatment.

Nursing turnover in a large, rural health system

PURPOSE

Nursing turnover is a leading cause of inefficiency in health care delivery. Few studies have examined turnover among nurses who work in rural areas.

METHODS

We accessed human resources data that tracked hiring and terminations from a large health system operating in South Dakota, North Dakota, and Minnesota between January 2016 and December 2017. Our study sample included 7,634 registered nurses, 1,765 of whom worked in a rural community. Within the health system, there were 27 affiliated hospitals, 17 of which were designated critical access hospitals. We estimated nursing turnover rates overall and stratified turnover rates by available demographic and occupational characteristics, including whether the nurse worked in a community with an affiliated acute care hospital or critical access hospital.

FINDINGS

Overall, 19% of nurses left their position between January 2016 and December 2017. Turnover rates were associated with state, nurse gender and age, and occupational tenure, but were similar in urban and rural areas. Of note, turnover rates were significantly higher in communities without an affiliated acute care hospital or critical access hospital.

CONCLUSION

Between 2016 and 2017, nearly 1 in 5 nurses working in this health system left their position. Turnover rates differed based on nurse demographics and selected occupational characteristics, including tenure. We also found higher turnover rates among nurses who worked in communities without an affiliated hospital, which points to a potential but unexplored benefit of hospitals in rural areas.

Association between nursing cost and patient outcomes in intensive care units: A retrospective cohort study of Belgian hospitals

INTRODUCTION

Hospitals with better nursing resources report more favourable patient outcomes with almost no difference in cost as compared to those with worse nursing resources. The aim of this study was to assess the association between nursing cost per intensive care unit bed and patient outcomes (mortality, readmission, and length of stay).

METHODOLOGY

This was a retrospective cohort study using data collected from the intensive care units of 17 Belgian hospitals from January 01 to December 31, 2018. Hospitals were dichotomized using median annual nursing cost per bed. A total of 18,235 intensive care unit stays were included in the study with 5,664 stays in the low-cost nursing group and 12,571 in the high-cost nursing group.

RESULTS

The rate of high length of stay outliers in the intensive care unit was significantly lower in the high-cost nursing group (9.2% vs 14.4%) compared to the low-cost nursing group. Intensive care unit readmission was not significantly different in the two groups. Mortality was lower in the high-cost nursing group for intensive care unit (9.9% vs 11.3%) and hospital (13.1% vs 14.6%) mortality. The nursing cost per intensive care bed was different in the two groups, with a median [IQR] cost of 159,387€ [140,307-166,690] for the low-cost nursing group and 214,032€ [198,094-230,058] for the high-cost group. In multivariate analysis, intensive care unit mortality (OR = 0.80, 95% CI: 0.69-0.92, p < 0.0001), in-hospital mortality (OR = 0.82, 95% CI: 0.72-0.93, p < 0.0001), and high length of stay outliers (OR = 0.48, 95% CI: 0.42-0.55, p < 0.0001) were lower in the high-cost nursing group. However, there was no significant effect on intensive care readmission between the two groups (OR = 1.24, 95% CI: 0.97-1.51, p > 0.05).

CONCLUSIONS

This study found that higher-cost nursing per bed was associated with significantly lower intensive care unit and in-hospital mortality rates, as well as fewer high length of stay outliers, but had no significant effect on readmission to the intensive care unit. .

Conditions of Nursing Practice in Hospitals and Nursing Homes Before COVID-19: Implications for Policy Action

Background

The COVID-19 pandemic has stimulated interest in potential policy solutions to improve working conditions in hospitals and nursing homes. Policy action in the pandemic recovery period must be informed by pre-pandemic conditions.

Purpose

To describe registered nurses' (RNs') working conditions, job outcomes, and measures of patient safety and care quality in hospitals and nursing homes just before the pandemic.

Methods

Cross-sectional study using descriptive statistics to analyze survey data from RNs in New York and Illinois collected December 2019 through February 2020.

Results

A total of 33,462 RNs were included in the final analysis. Before the pandemic, more than 40% of RNs reported high burnout, one in four were dissatisfied with their job, and one in five planned to leave their employer within 1 year. Among nursing home RNs, one in three planned to leave their employer. RNs reported poor working conditions characterized by not having enough staff (56%), administrators who did not listen/respond to RNs' concerns (42%), frequently missed nursing care (ranging from 8% to 34% depending on the nursing task in question), work that was interrupted or delayed by insufficient staff (88%), and performing non-nursing tasks (82%). Most RNs (68%) rated care quality at their workplace as less than excellent, and 41% gave their hospital an unfavorable patient safety rating.

Conclusion

Hospitals and nursing homes were understaffed before the COVID-19 pandemic, and many RNs were dissatisfied with their employers' contribution to the widespread observed shortage of nursing care during the pandemic. Policy interventions to address understaffing include the implementation of safe nurse staffing standards and passage of the Nurse Licensure Compact to permit RNs to move expeditiously to locales with the greatest needs.

Cost-quality tradeoff in nurse staffing: an exploration of USA hospitals facing market competition

Purpose

This research aims to explore the fine-grained relationships between nurse staffing and hospital operational performance with respect to care quality and operating costs. The authors also investigate the moderation effect of competition in local hospital markets on these relationships.

Design/methodology/approach

A six-year panel data is assembled from five separate sources to obtain information of 2,524 USA hospitals. Fixed-effect (FE) models are used to test the proposed hypotheses.

Findings

First, nurse staffing is initially associated with improved care quality until nurse staffing reaches a turning point, beyond which nurse staffing is associated with worse care quality. Second, a similar pattern applies to the relationship between nurse staffing and operating costs, although the turning point is at a much lower nurse staffing level. Third, market competition moderates the relationship between nurse staffing and care quality so that the turning point of nurse staffing will be higher when the degree of competition is higher. This shift of turning point is also observed in the relationship between nurse staffing and operating costs.

Practical implications

The study identifies three ranges of nurse staffing in which hospitals will likely experience simultaneous improvements, a tradeoff or simultaneous decline of care quality and operating costs when investing in more nursing capacity. Hospitals should adjust nurse staffing levels to the right directions to achieve better care or reduce operating costs.

Originality/value

Nurses constitute the largest provider group in hospitals and profoundly impact care quality and operating costs among all health care professionals. Optimizing the level of nurse staffing, therefore, can significantly impact the care quality and operating costs of hospitals.

Care Quality, Patient Safety, and Nurse Outcomes at Hospitals Serving Economically Disadvantaged Patients: A Case for Investment in Nursing

We sought to evaluate if better work environments or staffing were associated with improvements in care quality, patient safety, and nurse outcomes across hospitals caring for different proportions of patients who are economically disadvantaged. Few actionable approaches for hospitals with quality and resource deficits exist. One solution may be to invest in the nurse work environment and staffing. This cross-sectional study utilized secondary data from 23,629 registered nurses in 503 hospitals from a four-state survey collected in 2005-2008. Each 10% increase in the proportion of patients who are economically disadvantaged was associated with 27% and 22% decreased odds of rating unit-level care quality as excellent and giving an "A" safety grade, respectively. Each 10% increase was also associated with 9%, 25%, and 11% increased odds of job dissatisfaction, intent to leave, and burnout, respectively. The work environment had the largest association with each outcome. Accounting for the nurse work environment lessened or eliminated the negative outcomes experienced at hospitals serving high proportions of patients who are economically disadvantaged. Leaders at hospitals serving high proportions of patients who are economically disadvantaged, as well as state and federal policymakers, should work to improve quality, safety, and nurse outcomes by strengthening nurse work environments. Improving work environments highlights the role of nursing in the health care system, and policies focused on work environments are needed to improve the experiences of patients and nurses, especially at hospitals that care for many patients who are economically disadvantaged.

Patient outcomes and cost savings associated with hospital safe nurse staffing legislation: an observational study

OBJECTIVE

To evaluate variation in Illinois hospital nurse staffing ratios and to determine whether higher nurse workloads are associated with mortality and length of stay for patients, and cost outcomes for hospitals.

DESIGN

Cross-sectional analysis of multiple data sources including a 2020 survey of nurses linked to patient outcomes data.Setting: 87 acute care hospitals in Illinois.

PARTICIPANTS

210 493 Medicare patients, 65 years and older, who were hospitalised in a study hospital. 1391 registered nurses employed in direct patient care on a medical-surgical unit in a study hospital.

MAIN OUTCOME MEASURES

Primary outcomes were 30-day mortality and length of stay. Deaths avoided and cost savings to hospitals were predicted based on results from regression estimates if hospitals were to have staffed at a 4:1 ratio during the study period. Cost savings were computed from reductions in lengths of stay using cost-to-charge ratios.

RESULTS

Patient-to-nurse staffing ratios on medical-surgical units ranged from 4.2 to 7.6 (mean=5.4; SD=0.7). After adjusting for hospital and patient characteristics, the odds of 30-day mortality for each patient increased by 16% for each additional patient in the average nurse's workload (95% CI 1.04 to 1.28; p=0.006). The odds of staying in the hospital a day longer at all intervals increased by 5% for each additional patient in the nurse's workload (95% CI 1.00 to 1.09, p=0.041). If study hospitals staffed at a 4:1 ratio during the 1-year study period, more than 1595 deaths would have been avoided and hospitals would have collectively saved over $117 million.

CONCLUSIONS

Patient-to-nurse staffing ratios vary considerably across Illinois hospitals. If nurses in Illinois hospital medical-surgical units cared for no more than four patients each, thousands of deaths could be avoided, and patients would experience shorter lengths of stay, resulting in cost-savings for hospitals.

Matching One Sample According to Two Criteria in Observational Studies

Multivariate matching has two goals: (i) to construct treated and control groups that have similar distributions of observed covariates, and (ii) to produce matched pairs or sets that are homogeneous in a few key covariates. When there are only a few binary covariates, both goals may be achieved by matching exactly for these few covariates. Commonly, however, there are many covariates, so goals (i) and (ii) come apart, and must be achieved by different means. As is also true in a randomized experiment, similar distributions can be achieved for a high-dimensional covariate, but close pairs can be achieved for only a few covariates. We introduce a new polynomial-time method for achieving both goals that substantially generalizes several existing methods; in particular, it can minimize the earthmover distance between two marginal distributions. The method involves minimum cost flow optimization in a network built around a tripartite graph, unlike the usual network built around a bipartite graph. In the tripartite graph, treated subjects appear twice, on the far left and the far right, with controls sandwiched between them, and efforts to balance covariates are represented on the right, while efforts to find close individual pairs are represented on the left. In this way, the two efforts may be pursued simultaneously without conflict. The method is applied to our on-going study in the Medicare population of the relationship between superior nursing and sepsis mortality. The match2C package in R implements the method.

Hospital nurse staffing and patient outcomes in Chile: a multilevel cross-sectional study

BACKGROUND

Unrest in Chile over inequalities has underscored the need to improve public hospitals. Nursing has been overlooked as a solution to quality and access concerns, and nurse staffing is poor by international standards. Using Chile's new diagnosis-related groups system and surveys of nurses and patients, we provide information to policy makers on feasibility, net costs, and estimated improved outcomes associated with increasing nursing resources in public hospitals.

METHODS

For this multilevel cross-sectional study, we used data from surveys of hospital nurses to measure staffing and work environments in public and private Chilean adult high-complexity hospitals, which were linked with patient satisfaction survey and discharge data from the national diagnosis-related groups database for inpatients. All adult patients on medical and surgical units whose conditions permitted and who had been hospitalised for more than 48 h were invited to participate in the patient experience survey until 50 responses were obtained in each hospital. We estimated associations between nurse staffing and work environment quality with inpatient 30-day mortality, 30-day readmission, length of stay (LOS), patient experience, and care quality using multilevel random-effects logistic regression models and zero-truncated negative binomial regression models, with clustering of patients within hospitals.

FINDINGS

We collected and analysed surveys of 1652 hospital nurses from 40 hospitals (34 public and six private), satisfaction surveys of 2013 patients, and discharge data for 761 948 inpatients. Nurse staffing was significantly related to all outcomes, including mortality, after adjusting for patient characteristics, and the work environment was related to patient experience and nurses' quality assessments. Each patient added to nurses' workloads increased mortality (odds ratio 1·04, 95% CI 1·01-1·07, p<0·01), readmissions (1·02, 1·01-1·03, p<0·01), and LOS (incident rate ratio 1·04, 95% CI 1·01-1·06, p<0·05). Nurse workloads across hospitals varied from six to 24 patients per nurse. Patients in hospitals with 18 patients per nurse, compared with those in hospitals with eight patients per nurse, had 41% higher odds of dying, 20% higher odds of being readmitted, 41% higher odds of staying longer, and 68% lower odds of rating their hospital highly. We estimated that savings from reduced readmissions and shorter stays would exceed the costs of adding nurses by US$1·2 million and $5·4 million if the additional nurses resulted in average workloads of 12 or ten patients per nurse, respectively.

INTERPRETATION

Improved hospital nurse staffing in Chile was associated with lower inpatient mortality, higher patient satisfaction, fewer readmissions, and shorter hospital stays, suggesting that greater investments in nurses could return higher quality of care and greater value.

Evaluation of hospital nurse-to-patient staffing ratios and sepsis bundles on patient outcomes

BACKGROUND

Despite nurses' responsibilities in recognition and treatment of sepsis, little evidence documents whether patient-to-nurse staffing ratios are associated with clinical outcomes for patients with sepsis.

METHODS

Using linked data sources from 2017 including MEDPAR patient claims, Hospital Compare, American Hospital Association, and a large survey of nurses, we estimate the effect of hospital patient-to-nurse staffing ratios and adherence to the Early Management Bundle for patients with Severe Sepsis/Septic Shock SEP-1 sepsis bundles on patients' odds of in-hospital and 60-day mortality, readmission, and length of stay. Logistic regression is used to estimate mortality and readmission, while zero-truncated negative binomial models are used for length of stay.

RESULTS

Each additional patient per nurse is associated with 12% higher odds of in-hospital mortality, 7% higher odds of 60-day mortality, 7% higher odds of 60-day readmission, and longer lengths of stay, even after accounting for patient and hospital covariates including hospital adherence to SEP-1 bundles. Adherence to SEP-1 bundles is associated with lower in-hospital mortality and shorter lengths of stay; however, the effects are markedly smaller than those observed for staffing.

DISCUSSION

Improving hospital nurse staffing over and above implementing sepsis bundles holds promise for significant improvements in sepsis patient outcomes.

Is Hospital Nurse Staffing Legislation in the Public's Interest?: An Observational Study in New York State

BACKGROUND

The Safe Staffing for Quality Care Act under consideration in the New York (NY) state assembly would require hospitals to staff enough nurses to safely care for patients. The impact of regulated minimum patient-to-nurse staffing ratios in acute care hospitals in NY is unknown.

OBJECTIVES

To examine variation in patient-to-nurse staffing in NY hospitals and its association with adverse outcomes (ie, mortality and avoidable costs).

RESEARCH DESIGN

Cross-sectional data on nurse staffing in 116 acute care general hospitals in NY are linked with Medicare claims data.

SUBJECTS

A total of 417,861 Medicare medical and surgical patients.

MEASURES

Patient-to-nurse staffing is the primary predictor variable. Outcomes include in-hospital mortality, length of stay, 30-day readmission, and estimated costs using Medicare-specific cost-to-charge ratios.

RESULTS

Hospital staffing ranged from 4.3 to 10.5 patients per nurse (P/N), and averaged 6.3 P/N. After adjusting for potential confounders each additional patient per nurse, for surgical and medical patients, respectively, was associated with higher odds of in-hospital mortality [odds ratio (OR)=1.13, P=0.0262; OR=1.13, P=0.0019], longer lengths of stay (incidence rate ratio=1.09, P=0.0008; incidence rate ratio=1.05, P=0.0023), and higher odds of 30-day readmission (OR=1.08, P=0.0002; OR=1.06, P=0.0003). Were hospitals staffed at the 4:1 P/N ratio proposed in the legislation, we conservatively estimated 4370 lives saved and $720 million saved over the 2-year study period in shorter lengths of stay and avoided readmissions.

CONCLUSIONS

Patient-to-nurse staffing varies substantially across NY hospitals and higher ratios adversely affect patients. Our estimates of potential lives and costs saved substantially underestimate potential benefits of improved hospital nurse staffing.

Views of Bedouin physicians and nurses on nursing as a profession in Israel: There is more to strive for

Bedouin society poses challenges to attempts at modernization. Great efforts are being made to expand the number of nurses coming from the Bedouin population. This cross-sectional study among 201 Bedouin nurses and physicians from southern Israel examined differences in their views on nursing as a profession and its relationship to the working environment, using a self-administered questionnaire. Bedouin physicians demonstrated less positive attitudes towards the nursing profession than did nurses, but perceived the nursing work environment more positively. Compared to nurses, physicians ranked both nurses' involvement in policy practice and their clinical contribution to quality care lower, but scored nurses' dependence on physicians' orders higher. They also ranked teamwork and professional nursing development higher, and the autonomy of nurses lower. In conclusion, the perception of nursing as a profession in Bedouin society is linked to cultural fundamentals, gender, and the social status of women. Managers of multicultural teams, especially those including Bedouin-origin healthcare workers, should be aware of the effect of cultural background and should take care to address social disparities and eliminate differences in perspectives.
