An Examination of Hospital Nurse Staffing and Patient Experience with Care: Differences between Cross-Sectional and Longitudinal Estimates

Patient experience and nurse staffing level in South Korea

Patient experience has recently become a key driver for hospital quality improvement in South Korea, marked by the introduction of the Patient Experience Assessment (PXA) within its National Health Insurance in 2017. While the PXA has garnered special attention from the media and hospitals, there has been a lack of focus on its structural determinants, hindering continuous and sustained improvement in patient experience. Given the relatively low number of practicing nurses per 1000 population in South Korea and the significant variation in nurse staffing levels across hospitals, the staffing level of nurses in hospitals could be a crucial structural determinant of patient experience. This study examines the association between patient experience and hospital nurse staffing levels in South Korea. We used individual- and hospital-level data from the 2019 PXA, encompassing 7250 patients from 42 tertiary hospitals and 16 235 patients from 109 non-tertiary general hospitals with 300 or more beds. The dependent variables were derived from the complete set of 21 proper questions on patient experience in the Nurse and other domains. The main explanatory variable was the hospital-level Nurse Staffing Grade (NSG), employed by the National Health Insurance to adjust reimbursement to hospitals. Multilevel ordered/binomial logistic or linear regression was conducted accounting for other hospital- and patient-level characteristics as well as acknowledging the nested nature of the data. A clear, positive association was observed between patient experience in the Nurse domain and NSG, even after accounting for other characteristics. For example, the predicted probability of reporting the top-box category of "Always" to the question "How often did nurses treat you with courtesy and respect?" was 70.3% among patients from non-tertiary general hospitals with the highest NSG, compared to 63.1% among patients from their peer hospitals with the lowest NSG. Patient experience measured in other domains that were likely to be affected by nurse staffing levels also showed similar associations, although generally weaker and less consistent than in the Nurse domain. Better patient experience was associated with higher hospital nurse staffing levels in South Korea. Alongside current initiatives focused on measuring and publicly reporting patient experience, strengthening nursing and other hospital workforce should also be included in policy efforts to improve patient experience.

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 Structural Employee Empowerment on Hospital Ratings: Mediating Role of Social Climate and First-Line Managers' Resilience

Objective

The purpose of this article is to investigate the relationship between the structural empowerment of first-line health managers and health facility performance, examining the mediating roles of resilience and social climate in shaping the ratings of Slovak hospitals. Additionally, we aim to investigate the deeper mechanisms of this relationship, particularly the impact of resilience and the social climate, which can positively influence it.

Materials and Methods

The data collection was conducted through a questionnaire survey in February 2022. Respondents included 540 healthcare managers at the first level of management from 44 Slovak hospitals, all of which were part of the evaluation by the Institute for Economic and Social Reforms (INEKO). The analysis involved the use of the PLS-SEM method to examine the relationships between variables and assess direct and indirect effects, utilizing SmartPLS 3.3 software.

Results

The findings reveal a positive association between the structural empowerment of first-level managers and the ranking of health facilities. The hypotheses regarding the mediation of both variables - First-Level Managers' (FLMs) resilience and social climate - are supported, whether considered separately or jointly. In the case of joint mediation, a significant portion of the indirect effect is conveyed through FLMs' resilience, suggesting a potential avenue of support from hospital management to enhance health facility ratings.

Conclusion

Structural empowerment of first-line managers establishes the conditions for improving the ratings of health facilities. The total effect is significantly more pronounced in promoting their resilience and fostering a supportive social climate.

Measuring patients' experience of nursing quality in acute hospitals: review of existing scales and development and psychometric validation of a new scale

OBJECTIVE

To provide an overview of existing instruments measuring patient-perceived quality of nursing care and to develop and psychometrically evaluate a new multidimensional scale applicable to the German acute care sector.

DESIGN

We conducted a scale development and validation study involving the following phases: (1) performing a structured literature search to identify existing scales, (2) generating an initial pool of items using the results of the literature search and expert interviews, (3) coding/categorising the item pool, (4) organising a peer researcher workshop to select relevant items, (5) drafting the survey questionnaire and conducting cognitive pretesting, (6) pilot testing the survey questionnaire, (7) administering the survey to a large sample of hospital patients and (8) conducting a psychometric evaluation comprising exploratory factor analysis using the survey results, followed by confirmatory factor analysis and reliability and validity assessment of the resulting draft scale.

SURVEY PARTICIPANTS

17 859 recently hospitalised patients discharged from non-intensive care in non-paediatric and non-psychiatric hospital units in Germany between May and October 2019.

RESULTS

We identified 32 instruments comprising 635 items on nursing care quality. Alongside 135 indicators derived from expert interviews, these formed our initial item pool, which we coded into 15 categories. From this pool, 36 items were selected in the peer researcher workshop for pretesting and psychometric evaluation. Based on the results of our exploratory and confirmatory factor analyses, we propose a second-order scale to measure Patients' Experience of Nursing Quality in Acute Hospitals (PENQuAH), including the two higher-order dimensions 'patients' perception of direct nursing care activities' and 'patients' perception of guidance provided by nurses'. The results of various tests suggest the scale has sufficient goodness of fit, reliability and validity.

CONCLUSIONS

The PENQuAH scale is promising in terms of its psychometric properties, the plausibility and meaningfulness of its dimensions, and its ease of use.

Older Adults’ Interpretation of Nurses’ Nonverbal Communication in Cameroon: A Grounded Theory Inquiry

Communication is central to nursing care. Yet, the nonverbal aspect of communication tends to be neglected or underestimated in nursing studies. Research has shown that older patients interpret nurses’ communication messages during the clinical encounter. This article conceptualizes older adults’ interpretation of and need for nonverbal communication (NVC) to enhance patient-centered communication advocated by the World Health Organization. The Corbin and Strauss (2015) inductive Grounded Theory approach was used to collect data from 3 hospital units in Cameroon using in-depth interviews with eight older adults, thirteen nurses, and four student nurses between July 2018 and January 2020. Open coding, axial coding, and selective coding were used for analysis, which reveals that interpretations of NVC can be positive or negative. It means that older adults view nurses either as angels or as difficult persons, depending on the nurses’ positive or negative NVC and behaviors. These interpretations lead to consequences ranging from a preference for some nurses to noncompliance with care. The results further show that older adults need active listening, humor, and affection from nurses. Information regarding older adults’ interpretation of and need for NVC can be used to improve curriculum content and to develop skills in and awareness of NVC with older adults. It is recommended that further research expand on effective nonverbal techniques during COVID-19 times where the meaning of facial expressions and voice inflection can be disrupted.

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.

Nurse staffing and patient-perceived quality of nursing care: a cross-sectional analysis of survey and administrative data in German hospitals

OBJECTIVE

To examine the impact of nurse staffing on patient-perceived quality of nursing care. We differentiate nurse staffing levels and nursing skill mix as two facets of nurse staffing and use a multidimensional instrument for patient-perceived quality of nursing care. We investigate non-linear and interaction effects.

SETTING

The study setting was 3458 hospital units in 1017 hospitals in Germany.

PARTICIPANTS

We contacted 212 554 patients discharged from non-paediatric, non-intensive and non-psychiatric hospital units who stayed at least two nights in the hospital between January and October 2019. Of those, 30 174 responded, yielding a response rate of 14.2%. Our sample included only those patients. After excluding extreme values for our nurse staffing variables and removing observations with missing values, our final sample comprised 28 136 patients ranging from 18 to 97 years of age (average: 61.12 years) who had been discharged from 3458 distinct hospital units in 1017 hospitals.

PRIMARY AND SECONDARY OUTCOME MEASURES

Patient-perceived quality of nursing care (general nursing care, guidance provided by nurses, and patient loyalty to the hospital).

RESULTS

For all three dimensions of patient-perceived quality of nursing care, we found that they significantly decreased as (1) nurse staffing levels decreased (with decreasing marginal effects) and (2) the proportion of assistant nurses in a hospital unit increased. The association between nurse staffing levels and quality of nursing care was more pronounced among patients who were less clinically complex, were admitted to smaller hospitals or were admitted to medical units.

CONCLUSIONS

Our results indicate that, in addition to nurse staffing levels, nursing skill mix is crucial for providing the best possible quality of nursing care from the patient perspective and both should be considered when designing policies such as minimum staffing regulations to improve the quality of nursing care in hospitals.

The Association of Hospital Magnet® Status and Pay-for-Performance Penalties

The Centers for Medicare and Medicaid Services' Pay-for-Performance (P4P) programs aim to improve hospital care through financial incentives for care quality and patient outcomes. Magnet^® recognition-a potential pathway for improving nurse work environments-is associated with better patient outcomes and P4P program scores, but whether these indicators of higher quality are substantial enough to avoid penalties and thereby impact hospital reimbursements is unknown. This cross-sectional study used a national sample of 2,860 hospitals to examine the relationship between hospital Magnet^® status and P4P penalties under P4P programs: Hospital Readmission Reduction Program, Hospital-Acquired Conditions (HAC) Reduction Program, Hospital Value-Based Purchasing (VBP) Program. Magnet^® hospitals were matched 1:1 with non-Magnet hospitals accounting for 13 organizational characteristics including hospital size and location. Post-match logistic regression models were used to compute a hospital's odds of penalties. In a national sample of hospitals, 77% of hospitals experienced P4P penalties. Magnet^® hospitals were less likely to be penalized in the VBP program compared to their matched non-Magnet counterparts (40% vs. 48%). Magnet^® status was associated with 30% lower odds of VBP penalties relative to non-Magnet hospitals. Lower P4P program penalties is one benefit associated with achieving Magnet^® status or otherwise maintaining high-quality nurse work environments.

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

OBJECTIVE

To examine how estimates of the association between nurse staffing and patient length of stay (LOS) change with data aggregation over varying time periods and settings, and statistical controls for unobserved heterogeneity.

DATA SOURCES/STUDY SETTING

Longitudinal secondary data from October 2002 to September 2006 for 215 intensive care units and 438 general acute care units at 143 facilities in the Veterans Affairs (VA) health care system.

RESEARCH DESIGN

This retrospective observational study used unit-level panel data to analyze the association between nurse staffing and LOS. This association was measured over both a month-long and a year-long period, with and without fixed effects.

DATA COLLECTION

We used VA administrative data to obtain patient data on the severity of illness and LOS, as well as labor hours and wages for each unit by month.

PRINCIPAL FINDINGS

Overall, shorter LOS was associated with higher nurse staffing hours and lower proportions of hours provided by licensed professional nurses (LPNs), unlicensed personnel, and contract staff. Estimates of the association between nurse staffing and LOS changed in magnitude when aggregating data over years instead of months, in different settings, and when controlling for unobserved heterogeneity.

CONCLUSIONS

Estimating the association between nurse staffing and LOS is contingent on the time period of analysis and specific methodology. In future studies, researchers should be aware of these differences when exploring nurse staffing and patient outcomes.

Predictors of a Top-Box Patient Experience: A Retrospective Observational Study of HCAHPS Data at a Safety Net Institution

Hospitals commonly seek to improve patient experience as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, yet there are limited data to guide improvement efforts. The HCAHPS survey was developed for interhospital comparisons, whereas its use in intrahospital comparisons has not been validated. We sought to better understand the validity of utilizing intrahospital score comparisons and to identify the factors that may predict top-box HCAHPS scores. We performed a retrospective observational cohort study at an academic urban safety-net hospital examining 4898 HCAHPS surveys completed by hospitalized patients. We found that while most Patient-Mix Adjustment factors for which HCAHPS scores are adjusted were associated with top-box scores on intrahospital comparisons, few additional variables were associated with top-box scores. Further, HCAHPS questions pertaining to nurse and doctor communication were highly correlated with overall hospital rating, suggesting that communication-related factors may influence a patient’s hospital experience more strongly than do administrative factors.

Examining the Business Case for Patient Experience: A Systematic Review

EXECUTIVE SUMMARY

Hospitals, physician groups, and other healthcare providers are investing in improved patient care experiences. Prior reviews have concluded that better patient care experiences are associated with less healthcare utilization and better adherence to recommended prevention and treatment, clinical outcomes, and patient safety within hospitals. No comprehensive review has examined the business case for investing in patient experiences. This article reviews the literature on associations between patient experience-measured from the perspective of patients and families-and business outcomes, including patient allegiance and retention, complaints, lawsuits, provider job satisfaction, and profitability. We searched U.S. English-language peer-reviewed articles from January 1990 to July 2019. We followed the preferred reporting items for systematic reviews and meta-analyses guidelines and undertook a full-text review of 564 articles, yielding the inclusion of 40 articles. Our review found that patients with positive care experiences are more likely to return to the same hospital and ambulatory settings for future healthcare needs, retain their health plan, and voice fewer complaints. Associations between patient experiences and profitability or provider job satisfaction were limited/mixed. This suggests that providers can pursue better patient care experiences for the intrinsic value to patients, while also recognizing it is good for intermediate business outcomes: specifically increased recommendations, better patient retention, and fewer complaints. Nursing and physician care, broadly defined, are the only specific aspects of patient experience consistently associated with retention, with evidence pointing to communication and trust as parts of care linked to the intent to return. These aspects of patient experience are also the largest contributors to the overall ratings of a provider or facility.

Associations between Nurse Staffing Levels, Patient Experience, and Hospital Rating

The current study aimed to examine patient experience scores and differences in the scores based on the region and nurse staffing level of hospitals as well as to verify the effect of nurse-related patient experience scores on the overall rating of hospitals. Secondary data from the second Korean Patient Experience Survey-conducted using the cross-sectional design method-were analyzed, and 146 hospitals were included. Patient experience scores included six dimensions, and hospitals were categorized as: tertiary or general hospitals based on their type; capital and non-capital region hospitals based on regions; and beds-nurse or patients-nurse ratios were used based on nurse staffing levels. Pearson's correlation, simple regression, and multiple regression analysis methods were used. Among the six patient experience dimensions, the nurse-related patient experience score of 86.0 was the highest, whereas patient rights score of 78.4 was lowest. Moreover, the patient experience score for general hospitals with low nurse staffing grade was low, and the nurse experience score affected the overall hospital rating in general hospitals (p = 0.040). Policies to improve nurse staffing level are required to provide high-quality nursing care focused on communication with patients, which can enhance patient experience and satisfaction.

Identifying Best Practices in Pharmacy Experience: An Analysis of Military Treatment Facilities With the Highest Pharmacy Patient Experience Scores

INTRODUCTION

Pharmacy patient experience within military treatment facilities (MTFs) is a significant indicator of healthcare quality, as hospital admissions correlate with medication use (Budnitz et al., 2006) and pharmacists have a unique opportunity to influence patients' health (Dalton & Byrne, 2017). To improve patient care across the military health system (MHS), we investigated best practices within MTF pharmacies with the highest patient experience scores.

MATERIALS AND METHODS

Researchers performed semi-structured telephone interviews with pharmacists, pharmacy technicians, and patient experience officers from three of the highest ranked MTF pharmacies according to outpatient satisfaction survey results to glean "best practice" approaches to patient care. Researchers utilized the Gioia approach as a guiding theory for qualitative analysis of the interview data, and the study was excluded from a requirement to obtain institutional review board approval due to the number of respondents in accordance with the Paperwork Reduction Act of 1980 guidelines.

RESULTS

Interview participants from highly rated pharmacies emphasized the importance of communication among and between staff and patients, staff engagement and morale, and supportive leadership at their facilities for creating a positive patient experience and clinical environment.

CONCLUSION

These findings provide valuable insights to improve public health in military-connected populations through improved patient care practices in pharmacies across the MHS. Initiatives aimed at improving health care for pharmacy patients should prioritize improved communication and structural support for team members to create patient-friendly environments, which enables pharmacists and technicians to connect with patients and positively impact health outcomes. Limitations include lack of comparison data for lower performing pharmacies; future research will explore practices at lower ranking pharmacies to provide insights into communication practices, environments, and staff relationships impacting patient experience scores as well as the role patient demographics (e.g., retirees vs. active duty) and characteristics including facility size play in potential improvements.

Older adult experience of care and staffing on hospital and community wards: a cross-sectional study

Background

Recent major concerns about the quality of healthcare delivered to older adults have been linked to inadequate staffing and a lack of patient-centred care. Patient experience is a key component of quality care - yet there has been little research on whether and how staffing levels and staffing types affect satisfaction amongst older adult hospital inpatients. This study aimed to evaluate the association between registered nurse and healthcare assistant staffing levels and satisfaction with care amongst older adult hospital inpatients, and to test whether any positive effect of higher staffing levels is mediated by staff feeling they have more time to care for patients.

Methods

Survey data from 4928 inpatients aged 65 years and older and 2237 medical and nursing staff from 123 acute and community medical wards in England, United Kingdom (UK) was collected through the Royal College of Psychiatrist’s Elder Care Quality Mark. The cross-sectional association between staffing ratios and older adult patient satisfaction, and mediation by staff perceived time to care, was evaluated using multi-level modelling, adjusted for ward type and with a random effect for ward identity.

Results

Higher numbers of patients per healthcare assistant were associated with poorer patient satisfaction (adjusted β = − 0.32, 95% CI − 0.55 to 0.10, p < 0.01), and this was found to be partially mediated by all ward staff reporting less time to care for patients (adjusted β = − 0.10, bias-corrected 95% CI − 1.16 to − 0.02). By contrast, in both unadjusted and adjusted models, the number of patients per registered nurse was not associated with patient satisfaction.

Conclusions

Older adult hospital patients may particularly value the type of care provided by healthcare assistants, such as basic personal care and supportive communication. Additionally, higher availability of healthcare assistants may contribute to all ward staff feeling more able to spend time with patients. However, high availability of registered nurses has been shown in other research to be vital for ensuring quality and safety of patient care. Future research should seek to identify the ideal balance of registered nurses and healthcare assistants for optimising a range of outcomes amongst older adult patients.

Combining Surgical Outcomes and Patient Experiences to Evaluate Hospital Gastrointestinal Cancer Surgery Quality

BACKGROUND

Assessments of surgical quality should consider both surgeon and patient perspectives simultaneously. Focusing on patients undergoing major gastrointestinal cancer surgery, we sought to characterize hospitals, and their patients, on both these axes of quality.

METHODS

Using the American College of Surgeons' National Surgical Quality Improvement Program registry, hospitals were profiled on a risk-adjusted composite measure of death or serious morbidity (DSM) generated from patients who underwent colectomy, esophagectomy, hepatectomy, pancreatectomy, or proctectomy for cancer between January 1, 2015 and December 31, 2016. These hospitals were also profiled using the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. Highest-performing hospitals on both quality axes, and their respective patients, were compared to the lowest-performing hospitals.

RESULTS

Overall, 60,526 patients underwent their cancer operation at 530 hospitals. There were 38 highest- and 48 lowest-performing hospitals. The correlation between quality axes was poor (ρ = 0.10). Compared to the lowest-performing hospitals, the highest-performing hospitals were more often NCI-designated cancer centers (29.0% vs. 4.2%, p = 0.002) and cared for a lower proportion of Medicaid patients (0.14 vs. 0.23, p < 0.001). Patients who had their operations at the lowest- versus highest-performing hospitals were more often black (17.2% vs. 8.4%, p < 0.001), Hispanic (8.3% vs. 3.5%, p < 0.001), functionally dependent (3.8% vs. 0.9%, p < 0.001), and not admitted from home (4.4% vs. 2.4%, p < 0.001).

CONCLUSIONS

Hospital performance varied when assessed by both risk-adjusted surgical outcomes and patient experiences. In this study, poor-performing hospitals appeared to be disproportionately serving disadvantaged and minority cancer patients.

Nursing in Chilean Hospitals: A Research Agenda to Inform Health Policies and Improve Patient Outcomes

Introduction:

The ongoing challenge for Chilean hospitals of meeting population health needs merits attention to the health care workforce. No studies have explored how nursing might contribute to addressing this challenge. International research shows that organizational characteristics of the nursing workforce and practice environment are associated with patient outcomes. Chile lacks actionable evidence that applies to its context of care.

Method:

First, a review of international literature was developed to synthesize evidence on the association between organizational characteristics of the nursing workforce and patient outcomes. Second, a review of literature and other nonacademic sources was performed to describe the context of care and data pertaining to nurses in Chilean hospitals. Third, a research agenda for efficient utilization of the hospital nursing workforce in Chile was proposed.

Results:

International evidence shows that low patient-to-nurse ratios, high skill mix, and good practice environments are associated with better patient outcomes. Chilean hospitals have financial constraints that greatly influence the context of nursing practice and the scarce data about nursing organization call for greater attention.

Conclusion:

The establishment and implementation of a research agenda is needed to build local evidence regarding effective organization of nurses to inform policies and to improve patient outcomes in Chile.

Nurse staffing levels, missed vital signs and mortality in hospitals: retrospective longitudinal observational study

Background

Low nurse staffing levels are associated with adverse patient outcomes from hospital care, but the causal relationship is unclear. Limited capacity to observe patients has been hypothesised as a causal mechanism.

Objectives

This study determines whether or not adverse outcomes are more likely to occur after patients experience low nurse staffing levels, and whether or not missed vital signs observations mediate any relationship.

Design

Retrospective longitudinal observational study. Multilevel/hierarchical mixed-effects regression models were used to explore the association between registered nurse (RN) and health-care assistant (HCA) staffing levels and outcomes, controlling for ward and patient factors.

Setting and participants

A total of 138,133 admissions to 32 general adult wards of an acute hospital from 2012 to 2015.

Main outcomes

Death in hospital, adverse event (death, cardiac arrest or unplanned intensive care unit admission), length of stay and missed vital signs observations.

Data sources

Patient administration system, cardiac arrest database, eRoster, temporary staff bookings and the Vitalpac system (System C Healthcare Ltd, Maidstone, Kent; formerly The Learning Clinic Limited) for observations.

Results

Over the first 5 days of stay, each additional hour of RN care was associated with a 3% reduction in the hazard of death [hazard ratio (HR) 0.97, 95% confidence interval (CI) 0.94 to 1.0]. Days on which the HCA staffing level fell below the mean were associated with an increased hazard of death (HR 1.04, 95% CI 1.02 to 1.07), but the hazard of death increased as cumulative staffing exposures varied from the mean in either direction. Higher levels of temporary staffing were associated with increased mortality. Adverse events and length of stay were reduced with higher RN staffing. Overall, 16% of observations were missed. Higher RN staffing was associated with fewer missed observations in high-acuity patients (incidence rate ratio 0.98, 95% CI 0.97 to 0.99), whereas the overall rate of missed observations was related to overall care hours (RN + HCA) but not to skill mix. The relationship between low RN staffing and mortality was mediated by missed observations, but other relationships between staffing and mortality were not. Changing average skill mix and staffing levels to the levels planned by the Trust, involving an increase of 0.32 RN hours per patient day (HPPD) and a similar decrease in HCA HPPD, would be associated with reduced mortality, an increase in staffing costs of £28 per patient and a saving of £0.52 per patient per hospital stay, after accounting for the value of reduced stays.

Limitations

This was an observational study in a single site. Evidence of cause is not definitive. Variation in staffing could be influenced by variation in the assessed need for staff. Our economic analysis did not consider quality or length of life.

Conclusions

Higher RN staffing levels are associated with lower mortality, and this study provides evidence of a causal mechanism. There may be several causal pathways and the absolute rate of missed observations cannot be used to guide staffing decisions. Increases in nursing skill mix may be cost-effective for improving patient safety.

Future work

More evidence is required to validate approaches to setting staffing levels. Other aspects of missed nursing care should be explored using objective data. The implications of findings about both costs and temporary staffing need further exploration.

Trial registration

This study is registered as ISRCTN17930973.

Multilevel moderated mediation model with ordinal outcome

Although increasingly complex models have been proposed in mediation literature, there is no model nor software that incorporates the multiple possible generalizations of the simple mediation model jointly. We propose a flexible moderated mediation model allowing for (1) a hierarchical structure of clustered data, (2) more and possibly correlated mediators, and (3) an ordinal outcome. The motivating data set is obtained from a European study in nursing research. Patients' willingness to recommend their treating hospital was recorded in an ordinal way. The research question is whether such recommendation directly depends on system-level features in the organization of nursing care, or whether these associations are mediated by 2 measurements of nursing care left undone and possibly moderated by nurse education. We have developed a Bayesian approach and accompanying program that takes all the above generalizations into account.

Patient Experience: A Call to Action for Nurse Leadership

Health care organizations recognize that it is difficult to achieve consistent excellence in patient experience. Nursing leaders cannot underestimate the importance of the role they play in efforts to improve the patient experience. This article outlines a call to action for nurse leaders to consider reframing the patient experience as a focal point for the entire organization's strategic approach and tactics. This involves facilitating a dialogue about the organization's patient experience definition; building a strong, positive organization culture; creating processes to ensure the engagement of all voices; ensuring a focus across the continuum of care; and addressing the key drivers of patient experience excellence.

Peplau's Theory of Interpersonal Relations: An Alternate Factor Structure for Patient Experience Data?

A confirmatory factor analysis of data from the responses of 12,436 patients to 16 items on the Consumer Assessment of Healthcare Providers and Systems-Hospital survey was used to test a latent factor structure based on Peplau's middle-range theory of interpersonal relations. A two-factor model based on Peplau's theory fit these data well, whereas a three-factor model also based on Peplau's theory fit them excellently and provided a suitable alternate factor structure for the data. Though neither the two- nor three-factor model fit as well as the original factor structure, these results support using Peplau's theory to demonstrate nursing's extensive contribution to the experiences of hospitalized patients.

Nurse Staffing Patterns and Patient Experience of Care: An Empirical Analysis of U.S. Hospitals

OBJECTIVE

To examine the relationship between nurse staffing patterns and patients' experience of care in hospitals with a particular focus on staffing flexibility.

DATA SOURCES/STUDY SETTING

The study sample comprised U.S. general hospitals between 2010 and 2012. Nurse staffing data came from the American Hospital Association Annual Survey, and patient experience data came from the Medicare Hospital Consumer Assessment of Healthcare Providers and Systems.

STUDY DESIGN

An observational research design was used entailing a pooled, cross-sectional data set. Regression models were estimated using generalized estimating equation (GEE) and hospital fixed effects. Nurse staffing patterns were assessed based on both levels (i.e., ratio of full-time equivalent nurses per 1,000 patient days) and composition (i.e., skill mix-percentage of registered nurses; staffing flexibility-percentage of part-time nurses).

PRINCIPAL FINDINGS

All three staffing variables were significantly associated with patient experience in the GEE analysis, but only staffing flexibility was significant in the fixed-effects analysis. A higher percentage of part-time nurses was positively associated with patient experience. Multiplicative and nonlinear effects for the staffing variables were also observed.

CONCLUSIONS

Among three staffing variables, flexibility was found to be the most important relative to patient experience. Unobserved hospital characteristics appear to underlie patient experience as well as certain nurse staffing patterns.
