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.

Conditional Effects of Race on Operative and Nonoperative Outcomes of Emergency General Surgery Conditions.

INTRODUCTION: Many emergency general surgery (EGS) conditions can be managed both operatively or nonoperatively; however, it is unknown whether the decision to operate affects Black and White patients differentially. METHODS: We identified a nationwide cohort of Black and White Medicare beneficiaries, hospitalized for common EGS conditions from July 2015 to June 2018. Using near-far matching to adjust for measurable confounding and an instrumental variable analysis to control for selection bias associated with treatment assignment, we compare outcomes of operative and nonoperative management in a stratified population of Black and White patients. Outcomes included in-hospital mortality, 30-day mortality, nonroutine discharge, and 30-day readmissions. An interaction test based on a t test was used to determine the conditional effects of operative versus nonoperative management between Black and White patients. RESULTS: A total of 556,087 patients met inclusion criteria, of which 59,519 (10.7%) were Black and 496,568 (89.3%) were White. Overall, 165,932 (29.8%) patients had an operation and 390,155 (70.2%) were managed nonoperatively. Significant outcome differences were seen between operative and nonoperative management for some conditions; however, no significant differences were seen for the conditional effect of race on outcomes. CONCLUSIONS: The decision to manage an EGS patient operatively versus nonoperatively has varying effects on surgical outcomes. These effects vary by EGS condition. There were no significant conditional effects of race on the outcomes of operative versus nonoperative management among universally insured older adults hospitalized with EGS conditions.

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.

Electronic Health Record Usability and Postsurgical Outcomes Among Older Adults With Dementia.

INTRODUCTION: Electronic health record (EHR) usability, defined as the extent to which the system can be used to complete tasks, can influence patient outcomes. The aim of this study is to assess the relationship between EHR usability and postsurgical outcomes of older adults with dementia including 30-day readmission, 30-day mortality, and length of stay (LOS). METHODS: A cross-sectional analysis of linked American Hospital Association, Medicare claims data, and nurse survey data was conducted using logistic regression and negative binominal models. RESULTS: The dementia population who received care in hospitals with better EHR usability were less likely to die within 30 days of their admission following surgery compared to hospitals with poorer EHR usability (OR: 0.79, 95% CI: 0.68-0.91, p = 0.001). EHR usability was not associated with readmission or LOS. DISCUSSION: Better nurse reported EHR usability has the potential to reduce mortality rates among older adults with dementia in hospitals.

Operative and Nonoperative Outcomes of Emergency General Surgery Conditions: An Observational Study Using a Novel Instrumental Variable.

OBJECTIVE: To determine the effect of operative versus nonoperative management of emergency general surgery conditions on short-term and long-term outcomes. BACKGROUND: Many emergency general surgery conditions can be managed either operatively or nonoperatively, but high-quality evidence to guide management decisions is scarce. METHODS: We included 507,677 Medicare patients treated for an emergency general surgery condition between July 1, 2015, and June 30, 2018. Operative management was compared with nonoperative management using a preference-based instrumental variable analysis and near-far matching to minimize selection bias and unmeasured confounding. Outcomes were mortality, complications, and readmissions. RESULTS: For hepatopancreaticobiliary conditions, operative management was associated with lower risk of mortality at 30 days [-2.6% (95% confidence interval: -4.0, -1.3)], 90 days [-4.7% (-6.50, -2.8)], and 180 days [-6.4% (-8.5, -4.2)]. Among 56,582 intestinal obstruction patients, operative management was associated with a higher risk of inpatient mortality [2.8% (0.7, 4.9)] but no significant difference thereafter. For upper gastrointestinal conditions, operative management was associated with a 9.7% higher risk of in-hospital mortality (6.4, 13.1), which increased over time. There was a 6.9% higher risk of inpatient mortality (3.6, 10.2) with operative management for colorectal conditions, which increased over time. For general abdominal conditions, operative management was associated with 12.2% increased risk of inpatient mortality (8.7, 15.8). This effect was attenuated at 30 days [8.5% (3.8, 13.2)] and nonsignificant thereafter. CONCLUSIONS: The effect of operative emergency general surgery management varied across conditions and over time. For colorectal and upper gastrointestinal conditions, outcomes are superior with nonoperative management, whereas surgery is favored for patients with hepatopancreaticobiliary conditions. For obstructions and general abdominal conditions, results were equivalent overall. These findings may support patients, clinicians, and families making these challenging decisions.

Examining disparities among older multimorbid emergency general surgery patients: An observational study of Medicare beneficiaries.

BACKGROUND: Qualifying comorbidity sets (QCS) are tools used to identify multimorbid patients at increased surgical risk. It is unknown how the QCS framework for multimorbidity affects surgical risk in different racial groups. METHODS: This retrospective cohort study included Medicare patients age ≥65.5 who underwent an emergency general surgery operation from 2015 to 2018. Our exposure was race and multimorbidity, included in our model as an interaction term. The primary outcome of the study was 30-day mortality. Secondary outcomes included routine discharge, 30-day readmission, length of stay, and complications. RESULTS: In total, 163,148 patients who underwent and operation were included in this study. Of these, 13,852 (8.5%, p < 0.001) were Black, and 149,296 (91.5%, p < 0.001) were White. Black multimorbid patients had no significant differences in 30-day mortality, routine discharge or 30-day readmission when compared to White multimorbid patients after risk-adjustment. Black multimorbid patients had significantly lower odds of complications (OR 0.89, p = 0.014) compared to White multimorbid patients. CONCLUSIONS: Our study of universally insured patients highlights the critical role of pre-operative health status and its association with surgical outcomes.

Nursing Resources Linked to Postsurgical Outcomes for Patients With Opioid Use Disorder: An Observational Study.

To determine whether better nursing resources (ie, nurse education, staffing, work environment) are each associated with improved postsurgical outcomes for patients with opioid use disorder (OUD). Background: Hospitalized patients with OUD are at increased risk of adverse outcomes. Evidence suggests that adverse postsurgical outcomes may be mitigated in hospitals with better nursing resources, but this has not been evaluated among surgical patients with OUD. Methods: Cross-sectional (2015-2016) data were utilized from the RN4CAST-US survey of hospital nurses, the American Hospital Association Annual Survey of hospitals, and state patient hospital discharge summaries. Multivariate logistic and zero-truncated negative binomial regression models were employed to examine the association between nursing resources and 30-day readmission, 30-day in-hospital mortality, and length of stay for surgical patients with OUD. Results: Of 919,601 surgical patients in 448 hospitals, 11,610 had identifiable OUD. Patients with compared to without OUD were younger and more often insured by Medicaid. Better nurse education, staffing, and work environment were each associated with better outcomes for all surgical patients. For patients with OUD, each 10% increase in the proportion of nurses with a bachelor's degree in nursing was associated with even lower odds of 30-day readmission (odds ratio [OR] = 0.88; P = 0.001), and each additional patient-per-nurse was associated with even lower odds of 30-day readmission (OR = 1.09; P = 0.024). Conclusions: All surgical patients fare better when cared for in hospitals with better nursing resources. The benefits of having more nurses with a bachelor's degree and fewer patients-per-nurse in hospitals appear greater for surgical patients with OUD.

Rates of Surgical Consultations After Emergency Department Admission in Black and White Medicare Patients.

Importance: A surgical consultation is a critical first step in the care of patients with emergency general surgery conditions. It is unknown if Black Medicare patients and White Medicare patients receive surgical consultations at similar rates when they are admitted from the emergency department. Objective: To determine whether Black Medicare patients have similar rates of surgical consultations when compared with White Medicare patients after being admitted from the emergency department with an emergency general surgery condition. Design, Setting, and Participants: This was a retrospective cohort study that took place at US hospitals with an emergency department and used a computational generalization of inverse propensity score weight to create patient populations with similar covariate distributions. Participants were Medicare patients age 65.5 years or older admitted from the emergency department for an emergency general surgery condition between July 1, 2015, and June 30, 2018. The analysis was performed during February 2022. Patients were classified into 1 of 5 emergency general surgery condition categories based on principal diagnosis codes: colorectal, general abdominal, hepatopancreatobiliary, intestinal obstruction, and upper gastrointestinal. Exposures: Black vs White race. Main Outcomes and Measures: Receipt of a surgical consultation after admission from the emergency department with an emergency general surgery condition. Results: A total of 1 686 940 patients were included in the study. Of those included, 214 788 patients were Black (12.7%) and 1 472 152 patients were White (87.3%). After standardizing for medical and diagnostic imaging covariates, Black patients had 14% lower odds of receiving a surgical consultation (odds ratio [OR], 0.86; 95% CI, 0.85-0.87) with a risk difference of -3.17 (95% CI, -3.41 to -2.92). After standardizing for socioeconomic covariates, Black patients remained at an 11% lower odds of receiving a surgical consultation compared with similar White patients (OR, 0.89; 95% CI, 0.88-0.90) with a risk difference of -2.49 (95% CI, -2.75 to -2.23). Additionally, when restricting the analysis to Black patients and White patients who were treated in the same hospitals, Black patients had 8% lower odds of receiving a surgical consultation when compared with White patients (OR, 0.92; 95% CI, 0.90-0.93) with a risk difference of -1.82 (95% CI, -2.18 to -1.46). Conclusions and Relevance: In this study, Black Medicare patients had lower odds of receiving a surgical consultation after being admitted from the emergency department with an emergency general surgery condition when compared with similar White Medicare patients. These disparities in consultation rates cannot be fully attributed to medical comorbidities, insurance status, socioeconomic factors, or individual hospital-level effects.

Intensive Care Unit Utilization Following Major Surgery and the Nurse Work Environment.

BACKGROUND: Across hospitals, there is wide variation in ICU utilization after surgery. However, it is unknown whether and to what extent the nurse work environment is associated with a patient's odds of admission to an intensive care unit. PURPOSE: To estimate the relationship between hospitals' nurse work environment and a patient's likelihood of ICU admission and mortality following surgery. METHODS: A cross-sectional study of 269 764 adult surgical patients in 453 hospitals was conducted. Logistic regression models were used to estimate the effects of the work environment on the odds of patients' admission to the intensive care unit and mortality. RESULTS: Patients in hospitals with good work environments had 16% lower odds of intensive care unit admission and 15% lower odds of mortality or intensive care unit admission than patients in hospitals with mixed or poor environments. CONCLUSIONS: Patients in hospitals with better nurse work environments were less likely to be admitted to an intensive care unit and less likely to die. Hospitals with better nurse work environments may be better equipped to provide postoperative patient care on lower acuity units.

Association of hospital nursing and postsurgical sepsis.

Despite concerted research and clinical efforts, sepsis remains a common, costly, and often fatal occurrence. Little evidence exists for the relationship between institutional nursing resources and the incidence and outcomes of sepsis after surgery. The objective of this study was to examine whether hospital nursing resource quality is associated with postsurgical sepsis incidence and survival. This cross-sectional, secondary data analysis used registered nurses' reports on hospital nursing resources-staffing, education, and work environment-and multivariate logistic regressions to model their association with risk-adjusted postsurgical sepsis and mortality in 568 hospitals across four states. Better work environment quality was associated with lower odds of sepsis. While the likelihood of death among septic patients was nearly seven times that of non-septic patients, better nursing resources were associated with reduced mortality for all patients. Whereas the preponderance of sepsis research has focused on clinical interventions to prevent and treat sepsis, this study describes organizational characteristics hospital administrators may modify through organizational change targeting nurse staffing, education, and work environments to improve patient outcomes.

Why Some Nurses Obtain Specialty Certification and Others Do Not.

OBJECTIVE: The aim of this study was to determine whether there are modifiable characteristics of nurses and hospitals associated with nurse specialty certification. BACKGROUND: Hospitals, nurses, and patients benefit from nurse specialty certification, but little actionable evidence guides administrators seeking higher hospital certification rates. METHODS: This is a cross-sectional, secondary data analysis of 20 454 nurses in 471 hospitals across 4 states. RESULTS: Rates of certified nurses varied significantly across hospitals. Higher odds of certification were associated with Magnet® recognition and better hospital work environments at the facility level, and with BSN education, unit type (most notably, oncology), older age, more years of experience, and full-time employment at the individual nurse level. CONCLUSION: Two strategies that hold promise for increasing nurse specialty certification are improving hospital work environments and preferentially hiring BSN nurses.

An Assessment of Patient, Caregiver, and Clinician Perspectives on the Post-discharge Phase of Care.

OBJECTIVE: We sought to elicit patients', caregivers', and health care providers' perceptions of home recovery to inform care personalization in the learning health system. SUMMARY BACKGROUND DATA: Postsurgical care has shifted from the hospital into the home. Daily care responsibilities fall to patients and their caregivers, yet stakeholder concerns in these heterogeneous environments, especially as they relate to racial inequities, are poorly understood. METHODS: Surgical oncology patients, caregivers, and clinicians participated in freelisting; an open-ended interviewing technique used to identify essential elements of a domain. Within 2 weeks after discharge, participants were queried on 5 domains: home independence, social support, pain control, immediate, and overall surgical impact. Salience indices, measures of the most important words of interest, were calculated using Anthropac by domain and group. RESULTS: Forty patients [20 whites and 20 African-Americans (AAs)], 30 caregivers (17 whites and 13 AAs), and 20 providers (8 residents, 4 nurses, 4 nurse practitioners, and 4 attending surgeons) were interviewed. Patients and caregivers attended to the personal recovery experience, whereas providers described activities and individuals associated with recovery. All groups defined surgery as life-changing, with providers and caregivers discussing financial and mortality concerns. Patients shared similar thoughts about social support and self-care ability by race, whereas AA patients described heterogeneous pain management and more hopeful recovery perceptions. AA caregivers expressed more positive responses than white caregivers. CONCLUSIONS: Patients live the day-to-day of recovery, whereas caregivers and clinicians also contemplate more expansive concerns. Incorporating relevant perceptions into traditional clinical outcomes and concepts could enhance the surgical experience for all stakeholders.

The Association of Nurse-Physician Teamwork and Mortality in Surgical Patients.

In this study we describe nurse-physician teamwork, estimate its association with surgical patient outcomes (30-day mortality and failure-to-rescue), and determine whether these relationships depend upon other modifiable hospital nursing characteristics (nurse staffing and education levels) known to be associated with patient outcomes. This cross-sectional analysis included linked data from 29,391 nurses representing 665 acute care hospitals and 1,321,904 adult patients who underwent a general surgical, vascular, or orthopedic procedure. Surgical patients cared for in hospitals with better nurse-physician teamwork had significantly lower odds of 30-day mortality (odds ratio [OR] = 0.95) and failure-to-rescue (OR = 0.95). In addition, the odds of death and failure-to-rescue were lower for patients in hospitals with both higher nurse-physician teamwork and more favorable patient-to-nurse staffing ratios. Similar trends were observed related to nursing education levels. Improving interprofessional teamwork is one strategy to improve patient outcomes with the added importance of also considering additional features of their nursing workforce.

Lower Postsurgical Mortality for Individuals with Dementia with Better-Educated Hospital Workforce.

OBJECTIVES: To investigate whether care in a hospital with more nurses holding at least a Bachelor of Science in Nursing (BSN) degree is associated with lower mortality for individuals with Alzheimer's disease and related dementias (ADRD) undergoing surgery ADRD. DESIGN: Cross-sectional data from 2006-07 Medicare claims were linked with the Multi-State Nursing Care and Patient Safety Survey of nurses in 4 states. SETTING: Adult, nonfederal, acute care hospitals in California, Florida, New Jersey, and Pennsylvania (N=531). PARTICIPANTS: Medicare beneficiaries aged 65 and older with and without ADRD undergoing general, orthopedic, or vascular surgery (N=353,333; ADRD, n=46,163; no ADRD, n=307,170). MEASUREMENTS: Thirty-day mortality and failure to rescue (death after a complication). RESULTS: Controlling for hospital, procedure, and individual characteristics, each 10% increase in the proportion of BSN nurses was associated with 4% lower odds of death (odds ratio (OR)=0.96, 95% confidence interval (CI)=0.93-0.98) for individuals without ADRD, but 10% lower odds of death (OR=0.90, 95% CI=0.87-0.94) for those with ADRD. Each 10% increase in the proportion of nurses holding a BSN degree or higher was associated with 5% lower odds of failure to rescue (OR=0.95, 95% CI=0.92-0.98) for individuals without ADRD but 10% lower odds of failure to rescue (OR=0.90, 95% CI=0.87-0.94) for those with ADRD. CONCLUSION: Individuals undergoing surgery who have coexisting ADRD are more likely to die within 30 days of admission and die after a complication than those without ADRD. Having more BSN nurses in the hospital improves the odds of good outcomes for all individuals and has a much greater effect in individuals with ADRD.

Reducing Hospital Readmission Disparities of Older Black and White Adults After Elective Joint Replacement: The Role of Nurse Staffing.

OBJECTIVES: To examine racial differences in readmissions of older adults undergoing elective total hip and knee replacement, to determine the relationship between nurse staffing and readmission, and to study whether the relationship between staffing and readmission differs for older black and white adults. DESIGN: Cross-sectional analysis of multiple linked secondary data sources. SETTING: Nonfederal acute care hospitals in California, Florida, New Jersey, and Pennsylvania (n = 483). PARTICIPANTS: Patients aged 65 and older undergoing elective total hip or total knee replacement (N = 106,848; n = 102,762 white, n = 4,086 black). MEASUREMENTS: Unplanned readmission within 30 days of discharge. RESULTS: Older black patients were more likely to have an unplanned readmission (7.5%) than their white counterparts (5.6%). Even after adjusting for patient- and hospital-level factors, older black patients had 40% greater likelihood of readmission (odds ratio (OR) = 1.40, 95% confidence interval (CI) = 1.21-1.61). Each additional patient per nurse was associated with 8% greater odds of readmission for older white patients (OR = 1.08, 95% CI = 1.01-1.15) and 15% greater odds for older black patients (OR = 1.15, 95% CI = 1.08-1.22) after adjusting for patient- and hospital-level factors. CONCLUSION: Older minorities are more likely than their white counterparts to experience an unplanned readmission after elective orthopedic surgery. More-favorable nurse staffing was associated with lower odds of readmission of older black and white patients, but better-staffed hospitals had a greater protective effect for older black patients.

RN assessments of excellent quality of care and patient safety are associated with significantly lower odds of 30-day inpatient mortality: A national cross-sectional study of acute-care hospitals.

BACKGROUND: Quality and safety in health care has been increasingly in focus during the past 10-15 years. Stakeholders actively discuss ways to measure safety and quality of care to improve the health care system as a whole. Defining and measuring quality and safety, however, is complicated. One underutilized resource worthy of further exploration is the use of registered nurses (RNs) as informants of overall quality of care and patient safety. However, research is still scarce or lacking regarding RN assessments of patient safety and quality of care and their relationship to objective patient outcomes. OBJECTIVE: To investigate relationships between RN assessed quality of care and patient safety and 30-day inpatient mortality post-surgery in acute-care hospitals. DESIGN: This is a national cross-sectional study. DATA SOURCES: A survey (n=>10,000 RNs); hospital organizational data (n=67); hospital discharge registry data (n>200,000 surgical patients). DATA COLLECTION AND ANALYSIS: RN data derives from a national sample of RNs working directly with inpatient care in surgical/medical wards in acute-care hospitals in Sweden in 2010. Patient data are from the same hospitals in 2009-2010. Adjusted multivariate logistic regression models were used to estimate relationships between RN assessments and 30-day inpatient mortality. RESULTS: Patients cared for in hospitals where a high proportion of RNs reported excellent quality of care (the highest third of hospitals) had 23% lower odds of 30-day inpatient mortality compared to patients cared for in hospitals in the lowest third (OR 0.77, CI 0.65-0.91). Similarly, patients in hospitals where a high proportion of RNs reported excellent patient safety (highest third) had is 26% lower odds of death (OR 0.74, CI 0.60-0.91). CONCLUSIONS: RN assessed excellent patient safety and quality of care are related to significant reductions in odds of 30-day inpatient mortality, suggesting that positive RN reports of quality and safety can be valid indicators of these key variables.

Utilizing Home Healthcare Electronic Health Records for Telehomecare Patients With Heart Failure: A Decision Tree Approach to Detect Associations With Rehospitalizations.

Heart failure is a complex condition with a significant impact on patients' lives. A few studies have identified risk factors associated with rehospitalization among telehomecare patients with heart failure using logistic regression or survival analysis models. To date, there are no published studies that have used data mining techniques to detect associations with rehospitalizations among telehomecare patients with heart failure. This study is a secondary analysis of the home healthcare electronic medical record called the Outcome and Assessment Information Set-C for 552 telemonitored heart failure patients. Bivariate analyses using SAS and a decision tree technique using Waikato Environment for Knowledge Analysis were used. From the decision tree technique, the presence of skin issues was identified as the top predictor of rehospitalization that could be identified during the start of care assessment, followed by patient's living situation, patient's overall health status, severe pain experiences, frequency of activity-limiting pain, and total number of anticipated therapy visits combined. Examining risk factors for rehospitalization from the Outcome and Assessment Information Set-C database using a decision tree approach among a cohort of telehomecare patients provided a broad understanding of the characteristics of patients who are appropriate for the use of telehomecare or who need additional supports.

Comparison of the Value of Nursing Work Environments in Hospitals Across Different Levels of Patient Risk.

IMPORTANCE: The literature suggests that hospitals with better nursing work environments provide better quality of care. Less is known about value (cost vs quality). OBJECTIVES: To test whether hospitals with better nursing work environments displayed better value than those with worse nursing environments and to determine patient risk groups associated with the greatest value. DESIGN, SETTING, AND PARTICIPANTS: A retrospective matched-cohort design, comparing the outcomes and cost of patients at focal hospitals recognized nationally as having good nurse working environments and nurse-to-bed ratios of 1 or greater with patients at control group hospitals without such recognition and with nurse-to-bed ratios less than 1. This study included 25 752 elderly Medicare general surgery patients treated at focal hospitals and 62 882 patients treated at control hospitals during 2004-2006 in Illinois, New York, and Texas. The study was conducted between January 1, 2004, and November 30, 2006; this analysis was conducted from April to August 2015. EXPOSURES: Focal vs control hospitals (better vs worse nursing environment). MAIN OUTCOMES AND MEASURES: Thirty-day mortality and costs reflecting resource utilization. RESULTS: This study was conducted at 35 focal hospitals (mean nurse-to-bed ratio, 1.51) and 293 control hospitals (mean nurse-to-bed ratio, 0.69). Focal hospitals were larger and more teaching and technology intensive than control hospitals. Thirty-day mortality in focal hospitals was 4.8% vs 5.8% in control hospitals (P < .001), while the cost per patient was similar: the focal-control was -$163 (95% CI = -$542 to $215; P = .40), suggesting better value in the focal group. For the focal vs control hospitals, the greatest mortality benefit (17.3% vs 19.9%; P < .001) occurred in patients in the highest risk quintile, with a nonsignificant cost difference of $941 per patient ($53 701 vs $52 760; P = .25). The greatest difference in value between focal and control hospitals appeared in patients in the second-highest risk quintile, with mortality of 4.2% vs 5.8% (P < .001), with a nonsignificant cost difference of -$862 ($33 513 vs $34 375; P = .12). CONCLUSIONS AND RELEVANCE: Hospitals with better nursing environments and above-average staffing levels were associated with better value (lower mortality with similar costs) compared with hospitals without nursing environment recognition and with below-average staffing, especially for higher-risk patients. These results do not suggest that improving any specific hospital's nursing environment will necessarily improve its value, but they do show that patients undergoing general surgery at hospitals with better nursing environments generally receive care of higher value.

Achieving Kaiser Permanente quality.

BACKGROUND: The Kaiser Permanente model of integrated health delivery is highly regarded for high-quality and efficient health care. Efforts to reproduce Kaiser's success have mostly failed. One factor that has received little attention and that could explain Kaiser's advantage is its commitment to and investment in nursing as a key component of organizational culture and patient-centered care. PURPOSE: The aim of this study was to investigate the role of Kaiser's nursing organization in promoting quality of care. METHODOLOGY: This was a cross-sectional analysis of linked secondary data from multiple sources, including a detailed survey of nurses, for 564 adult, general acute care hospitals from California, Florida, Pennsylvania, and New Jersey in 2006-2007. We used logistic regression models to examine whether patient (mortality and failure-to-rescue) and nurse (burnout, job satisfaction, and intent-to-leave) outcomes in Kaiser hospitals were better than in non-Kaiser hospitals. We then assessed whether differences in nursing explained outcomes differences between Kaiser and other hospitals. Finally, we examined whether Kaiser hospitals compared favorably with hospitals known for having excellent nurse work environments-Magnet hospitals. FINDINGS: Patient and nurse outcomes in Kaiser hospitals were significantly better compared with non-Magnet hospitals. Kaiser hospitals had significantly better nurse work environments, staffing levels, and more nurses with bachelor's degrees. Differences in nursing explained a significant proportion of the Kaiser outcomes advantage. Kaiser hospital outcomes were comparable with Magnet hospitals, where better outcomes have been largely explained by differences in nursing. IMPLICATIONS: An important element in Kaiser's success is its investment in professional nursing, which may not be evident to systems seeking to achieve Kaiser's advantage. Our results suggest that a possible strategy for achieving outcomes like Kaiser may be for hospitals to consider Magnet designation, a proven and cost-effective strategy to improve process of care through investments in nursing.

Organization of Hospital Nursing and 30-Day Readmissions in Medicare Patients Undergoing Surgery.

BACKGROUND: Growing scrutiny of readmissions has placed hospitals at the center of readmission prevention. Little is known, however, about hospital nursing­a critical organizational component of hospital service system­in relation to readmissions. OBJECTIVES: To determine the relationships between hospital nursing factors­nurse work environment, nurse staffing, and nurse education­and 30-day readmissions among Medicare patients undergoing general, orthopedic, and vascular surgery. METHOD AND DESIGN: We linked Medicare patient discharge data, multistate nurse survey data, and American Hospital Association Annual Survey data. Our sample included 220,914 Medicare surgical patients and 25,082 nurses from 528 hospitals in 4 states (California, Florida, New Jersey, and Pennsylvania). Risk-adjusted robust logistic regressions were used for analyses. RESULTS: The average 30-day readmission rate was 10% in our sample (general surgery: 11%; orthopedic surgery: 8%; vascular surgery: 12%). Readmission rates varied widely across surgical procedures and could be as high as 26% (upper limb and toe amputation for circulatory system disorders). Each additional patient per nurse increased the odds of readmission by 3% (OR=1.03; 95% CI, 1.00-1.05). Patients cared in hospitals with better nurse work environments had lower odds of readmission (OR=0.97; 95% CI, 0.95-0.99). Administrative support to nursing practice (OR=0.96; 95% CI, 0.94-0.99) and nurse-physician relations (OR=0.97; 95% CI, 0.95-0.99) were 2 main attributes of the work environment that were associated with readmissions. CONCLUSIONS: Better nurse staffing and work environment were significantly associated with 30-day readmission, and can be considered as system-level interventions to reduce readmissions and associated financial penalties.
