Abstract

Background: Collaboration among healthcare providers has been considered a promising strategy for improving care quality and patient outcomes. Despite mounting evidence demonstrating the impact of collaboration on outcomes of healthcare providers, there is little empirical evidence on the relationship between collaboration and patient safety outcomes, particularly at the patient care unit level. Objectives: The purpose of this study is to identify the extent to which interdisciplinary collaboration between nurses and physicians and intradisciplinary collaboration among nurses on patient care units are associated with patient safety outcomes. Methods: This is a cross-sectional study using nurse survey data and patient safety indicators data from U.S. acute care hospital units. Collaboration at the unit level was measured by two 6-item scales: nurse-nurse interaction scale and nurse-physician interaction scale. Patient outcome measures included hospital-acquired pressure ulcers (HAPUs) and patient falls. The unit of analysis was the patient care unit, and the final sample included 900 units of 5 adult unit types in 160 hospitals in the U.S. Multilevel logistic and Poisson regressions were used to estimate the relationship between collaboration and patient outcomes. All models were controlled for hospital and unit characteristics, and clustering of units within hospitals was considered. Results: On average, units had 26 patients with HAPUs per 1000 patients and 3 patient falls per 1000 patient days. Critical care units had the highest HAPU rate (50/1000 patients) and the lowest fall rate (1/1000 patient days). A one-unit increase in the nurse-nurse interaction scale score led to 31% decrease in the odds of having a HAPU (OR, 0.69; 95% CI, 0.56–0.82) and 8% lower patient fall rate (IRR, 0.92; 95% CI, 0.87–0.98) on a nursing unit. A one-unit increase in the nurse-physician interaction scale score was associated with 19% decrease in the odds of having a HAPU (OR, 0.81; 95% CI, 0.68–0.97) and 13% lower fall rates (IRR, 0.87; 95% CI, 0.82–0.93) on a unit. Conclusions: Both nurse-physician collaboration and nurse-nurse collaboration were significantly associated with patient safety outcomes. Findings from this study suggest that improving collaboration among healthcare providers should be considered as an important strategy for promoting patient safety and both interdisciplinary and intradisciplinary collaboration are critical for achieving better patient outcomes.

Abstract

Purpose: To examine which characteristics of the practice environment were associated with missed nursing care in U.S. acute care hospital units. Design: A descriptive, correlational study used secondary analysis of the 2015 National Database of Nursing Quality Indicators® Registered Nurse (RN) Survey data. Subscales of the Practice Environment Scale of the Nursing Work Index were used to measure practice environment characteristics. The sample included 1,583 units in 371 hospitals, containing survey responses from 31,650 RNs. Methods: Multilevel logistic regression was performed to estimate the effects of the practice environment characteristics on missed care, controlling for hospital and unit characteristics. Results: About 84.1% of unit RNs reported missing at least one of the 15 necessary care activities. Good environment units had 63.3% significantly lower odds of having RNs miss care activities than poor environment units. Units had 81.5% lower odds of having RNs miss any necessary activities with 1 point increase of the staffing and resource adequacy score; 21.9% lower odds for 1 point increase in the nurse–physician relations score; and approximately 2.1 times higher odds with 1 point increase in the nurse participation in hospital affairs score. Conclusions: Good environments were significantly associated with lower levels of missed care. The impact on missed care differed by the characteristics of the practice environment. Clinical Relevance: Hospital and nursing administrators should maintain good practice environments for nurses to reduce missed care activities and thus potentially improve patient outcomes. Specifically, their efforts should be targeted on improving staffing and resource adequacy and nurse–physician relations and on reducing workloads on hospital affairs.

Abstract

Preventing hospital readmissions is one of the top priorities of the U.S. health care system. This systematic review examined the current evidence about hospital readmissions from home health care (HHC). Literature was searched in PubMed, CINAHL, PsycINFO, Scopus, and Web of Science. Eligible studies were reviewed and evaluated using a validated tool. Eighteen articles were reviewed. Reported readmission rates and risk factors varied dramatically between studies. Reasons for readmissions were understudied. Findings of reviewed studies were limited by small sample sizes, single data source, and methodological flaws. Future studies should use multiple national data sources across patients’ care spectrum and advanced statistical models to identify who among HHC patients are most likely to be readmitted to hospital and for what reason.

Abstract

Purpose: To examine the trends in baccalaureate (bachelor of science in nursing)–prepared registered nurses (BSN RNs) in U.S. acute care hospital units and to project the growth in the number of BSN RNs by 2020. Design: This is a longitudinal study using the Registered Nurse Education Indicators data (2004–2013) from the National Database of Nursing Quality Indicators. Methods: The level of BSN RNs in each unit was operationalized as the proportion of nurses holding a baccalaureate degree or higher among all the nurses in a unit. Our sample included 12,194 unit-years from 2,126 units of six cohorts in 377 U.S. acute care hospitals. A hierarchical linear regression model was used to examine the trends in BSN RNs and to project future growth in the number of BSN RNs when controlling for hospital and unit characteristics and considering repeated measures in units over time and clustering of units within hospitals. Results: The proportion of BSN RNs in U.S. acute care hospital units increased from 44% in 2004 to 57% in 2013 (a 30% increase); when combining all cohorts, this rate increased from 44% in 2009 to 51% in 2013. On average, the proportion of BSN RNs in a unit increased by 1.3% annually before 2010 and by 1.9% each year from 2010 on. The percentage of units having at least 80% of their nurses with a baccalaureate degree or higher increased from 3% in 2009 to 7% in 2013. Based on the current trends, 64% of the nurses working in a hospital unit will have a baccalaureate degree by 2020, and 22% of the units will reach the 80% goal by 2020. Conclusions: There was a significant increase in the proportion of BSN RNs in U.S. acute care hospital units over the past decade, particularly after 2010. However, given the current trends, it is unlikely that the goal of 80% nurses with a baccalaureate degree will be achieved by 2020. Clinical Relevance: The U.S. nursing workforce is under educational transformation in order to meet the increasing healthcare needs. To help accelerate this transformation, further advocacy, commitment, and investment are needed from all healthcare stakeholders (e.g., policymakers, executives and managers of healthcare facilities, nursing schools, etc.).

Abstract

Purpose: To identify how organizational nursing factors at different structural levels (i.e., unit-level work environment and hospital Magnet status) are associated with hospital-acquired pressure ulcers (HAPUs) in U.S. acute care hospitals. Design: A cross-sectional observational study used data from the National Database of Nursing Quality Indicators®. Responses from 33,845 registered nurses (RNs) were used to measure unit work environments. The unit of analysis was the nursing unit, and there were 1,381 units in 373 hospitals in the United States. Methods: Unit work environment was measured by the Practice Environment Scale of Nurse Working Index (PES-NWI). Multilevel logistic regressions were used to estimate the effects of unit work environment and hospital Magnet status on HAPUs. All models were controlled for hospital and unit characteristics when considering clustering of units within hospitals. Results: Magnet hospital units had 21% lower odds of having an HAPU than non-Magnet hospital units (95% confidence interval [CI], 0.64-0.98). With one unit increase of the PES-NWI score, units had 29% lower odds of having an HAPU (95% CI, 0.55-0.91). When including both hospital Magnet status and unit work environment in the model, hospital Magnet status no longer had a significant effect on HAPUs (odds ratio [OR] = 0.82; 95% CI, 0.66-1.02), whereas the significant effect of unit work environment persisted (OR = 0.73; 95% CI, 0.56-0.93). Conclusions: Both hospital and unit environments were significantly associated with HAPUs, and the unit-level work environment can be more influential in reducing HAPUs. Clinical Relevance: Investment in the nurse work environments at both the hospital level and unit level has the potential to reduce HAPUs; and additional to hospital-level initiatives (e.g., Magnet recognition program), efforts targeting on-unit work environments deserve more attention.

Abstract

OBJECTIVE: The objective of this study is to identify the effects of unit collaboration and nursing leadership on nurse outcomes and quality of care. BACKGROUND: Along with the current healthcare reform, collaboration of care providers and nursing leadership has been underscored; however, empirical evidence of the impact on outcomes and quality of care has been limited. METHODS: Data from 29742 nurses in 1228 units of 200 acute care hospitals in 41 states were analyzed using multilevel linear regressions. Collaboration (nurse-nurse collaboration and nurse-physician collaboration) and nursing leadership were measured at the unit level. Outcomes included nurse job satisfaction, intent to leave, and nurse-reported quality of care. RESULTS: Nurses reported lower intent to leave, higher job satisfaction, and better quality of care in units with better collaboration and stronger nursing leadership. CONCLUSION: Creating a care environment of strong collaboration among care providers and nursing leadership can help hospitals maintain a competitive nursing workforce supporting high quality of care.

Abstract

Background: Nursing unit is the micro-organization in the hospital health care system in which integrated patient care is provided. Nursing units of different types serve patients with distinct care goals, clinical tasks, and social structures and norms. However, empirical evidence is sparse on unit type differences in quality of care and its relation with nurse work environment. Nurse work environment has been found as an important nursing factor predicting nurse and patient outcomes. Objectives: To examine the unit type differences in nurse-reported quality of care, and to identify the association between unit work environment and quality of care by unit types. Methods: This is a cross-sectional study using nurse survey data (2012) from US hospitals nationwide. The nurse survey collected data on quality of care, nurse work environment, and other work related information from staff nurses working in units of various types. Unit types were systematically classified across hospitals. The unit of analysis was the nursing unit, and the final sample included 7677 units of 14 unit types from 577 hospitals in 49 states in the US. Multilevel regressions were used to assess the relationship between nurse work environment and quality of care across and by unit types. Results: On average, units had 58% of the nurses reporting excellent quality of care and 40% of the nurses reporting improved quality of care over the past year. Unit quality of care varied by unit types, from 43% of the nurses in adult medical units to 73% of the nurses in interventional units rating overall quality of care on unit as excellent, and from 35% of the nurses in adult critical care units to 44% of the nurses in adult medical units and medical-surgical combined units reporting improved quality of care. Estimates from regressions indicated that better unit work environments were associated with higher quality of care when controlling various hospital and unit covariates; and this association persisted among units of different types. Conclusions: Unit type differences exist in the overall quality of care as well as achievement in improving quality of care. The low rates of nurses reporting improvement in the quality of nursing care to patients suggest that further interventions focusing at the unit-level are needed for achieving high care quality. Findings from our study also suggest that improving nurse work environments can be an effective strategy to improve quality of care.

Abstract

Background: Growing scrutiny of readmissions has placed hospitals at the center of readmission prevention. Little is known, however, about hospital nursing-a critical organizational component of hospital service system-in relation to readmissions. Objectives: To determine the relationships between hospital nursing factors-nurse work environment, nurse staffing, and nurse education-and 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.

Abstract

Previous research supports the link among malnutrition, cognitive dysfunction, and behavioral outcomes; however, less research has focused on micronutrient deficiencies. This study investigates whether micronutrient deficiencies, specifically blood zinc and iron levels, will be associated with increased behavior problem scores, including internalizing and externalizing behaviors. 1314 Children (55% boys and 45% girls) from the Jintan Preschool Cohort in China participated in this study. Venous blood samples were collected and analyzed for zinc and iron when the children were 3-5 years old. Behavior problems were measured with the Child Behavior Checklist (CBCL), which was completed by the parents when children were in their last months of preschool (mean age 5.6 years). General linear multivariate modeling was used, with adjustment for important sociodemographic variables. The results indicate that low zinc levels alone (p = 0.024) and combined low zinc and iron levels (p = 0.022) are significantly associated with increased reports of total behavior problems. We did not find an association between low iron and behavior problems. With regards to sociodemographics, living in the suburbs is associated with increased internalizing problems, while higher mother's education and being female were associated with decreased externalizing problems. This study suggests that micronutrient deficiencies and sociodemographic facts are associated with behavior problems in preschoolers.
