Psychiatric comorbidity and greater hospitalization risk, longer length of stay, and higher hospitalization costs in older adults with heart failure

Sayers, S. L., Hanrahan, N., Kutney, A., Clarke, S. P., Reis, B. F., & Riegel, B. (2007). Journal of the American Geriatrics Society, 55(10), 1585-1591. 10.1111/j.1532-5415.2007.01368.x
Abstract
Abstract
OBJECTIVES: To explore associations between psychiatric comorbidity and rehospitalization risk, length of hospitalization, and costs. DESIGN: Cross-sectional study of 1-year hospital administrative data. SETTING: Claims-based study of older adults hospitalized in the United States. PARTICIPANTS: Twenty-one thousand four hundred twenty-nine patients from a 5% national random sample of U.S. Medicare beneficiaries aged 65 and older, with at least one acute care hospitalization in 1999 with a Diagnostic-Related Group of congestive heart failure. MEASUREMENTS: The number of hospitalizations, mean length of hospital stay, and total hospitalization costs in calendar year 1999. RESULTS: Overall, 15.8% of patients hospitalized for heart failure (HF) had a coded psychiatric comorbidity; the most commonly coded comorbid psychiatric disorder was depression (8.5% of the sample). Most forms of psychiatric comorbidity were associated with greater inpatient utilization, including risk of additional hospitalizations, days of stay, and hospitalization charges. Additional hospitalization costs associated with psychiatric comorbidity ranged up to $7,763, and additional days length of stay ranged up to 1.4 days. CONCLUSION: Psychiatric comorbidity appears in a significant minority of patients hospitalized for HF and may affect their clinical and economic outcomes. The associations between psychiatric comorbidity and use of inpatient care are likely to be an underestimate, because psychiatric illness is known to be underdetected in older adults and in hospitalized medical patients.

Racial segregation and differential outcomes in hospital care

Clarke, S. P., Davis, B. L., & Nailon, R. E. (2007). Western Journal of Nursing Research, 29(6), 739-757. 10.1177/0193945907303167
Abstract
Abstract
This exploratory study of patients in Pennsylvania (PA) and Virginia (VA) hospitals in 1998-1999 measures the segregation of care for Black patients receiving inpatient care for specific medical and surgical conditions. It also examined inpatient mortality risk for Black patients and the impact of treatment in heavily segregated hospitals on mortality for Blacks and non-Blacks. Segregation of hospital care was found across both states but was more pronounced in PA. Blacks did not experience higher mortality rates than non-Blacks either before or after controls for clinical risk factors in either state and for certain admission types had lower mortality. Both Black and non-Black surgical, heart failure, and lung disease patients treated in VA hospitals with more Black patients had poorer outcomes. Future research should examine how access, patient choice, hospital organization, processes of care, and factors related to nursing care might influence hospital outcomes for patients from different racial backgrounds.

Sharp-device injuries to hospital staff nurses in 4 countries

Clarke, S. P., Schubert, M., & Körner, T. (2007). Infection Control and Hospital Epidemiology, 28(4), 473-478. 10.1086/513445
Abstract
Abstract
OBJECTIVE. To compare sharp-device injury rates among hospital staff nurses in 4 Western countries. DESIGN. Cross-sectional survey. SETTING. Acute-care hospital nurses in the United States (Pennsylvania), Canada (Alberta, British Columbia, and Ontario), the United Kingdom (England and Scotland), and Germany. PARTICIPANTS. A total of 34,318 acute-care hospital staff nurses in 1998-1999. RESULTS. Survey-based rates of retrospectively-reported needlestick injuries in the previous year for medical-surgical unit nurses ranged from 146 injuries per 1,000 full-time equivalent positions (FTEs) in the US sample to 488 injuries per 1,000 FTEs in Germany. In the United States and Canada, very high rates of sharp-device injury among nurses working in the operating room and/or perioperative care were observed (255 and 569 injuries per 1,000 FTEs per year, respectively). Reported use of safety-engineered sharp devices was considerably lower in Germany and Canada than it was in the United States. Some variation in injury rates was seen across nursing specialties among North American nurses, mostly in line with the frequency of risky procedures in the nurses' work. CONCLUSIONS. Studies conducted in the United States over the past 15 years suggest that the rates of sharp-device injuries to front-line nurses have fallen over the past decade, probably at least in part because of increased awareness and adoption of safer technologies, suggesting that regulatory strategies have improved nurse safety. The much higher injury rate in Germany may be due to slow adoption of safety devices. Wider diffusion of safer technologies, as well as introduction and stronger enforcement of occupational safety and health regulations, are likely to decrease sharp-device injury rates in various countries even further.

Supplemental nurse staffing in hospitals and quality of care

Aiken, L. H., Xue, Y., Clarke, S. P., & Sloane, D. M. (2007). Journal of Nursing Administration, 37(7), 335-342. 10.1097/01.NNA.0000285119.53066.ae
Abstract
Abstract
To promote evidence-based decision making regarding hospital staffing, the authors examined the characteristics of supplemental nurses, as well as the relationship of supplemental staff to nurse outcomes and adverse events. The use of supplemental nurses to bolster permanent nursing staff in hospitals is widespread but controversial. Quality concerns have been raised regarding the use of supplemental staff. Data from the 2000 National Sample Survey of Registered Nurses were used to determine whether the qualifications of supplemental nurses working in hospitals differed from permanent staff nurses. Data from Pennsylvania nurse surveys were analyzed to examine whether nurse outcomes and adverse events differed in hospitals with varying proportions of nonpermanent nurses. Temporary nurses have qualifications similar to permanent staff nurses. Deficits in patient care environments in hospitals employing more temporary nurses explain the association between poorer quality and temporary nurses. Negative perceptions of temporary nurses may be unfounded.

Validation of the basel extent of rationing of nursing care instrument

Schubert, M., Glass, T. R., Clarke, S. P., Schaffert-Witvliet, B., & De Geest, S. (2007). Nursing Research, 56(6), 416-424. 10.1097/01.NNR.0000299853.52429.62
Abstract
Abstract
Background: Financial constraints and other forces affecting health care in many countries have led to nurses implicitly limiting their care in some instances. In the absence of an accepted definition and theoretical framework of implicit rationing of nursing care, a framework and the Basel Extent of Rationing of Nursing Care (BERNCA) instrument were developed. This instrument was used in the Swiss part of the International Hospital Outcome Study, in which implicit rationing of nursing care was studied. Objective: To examine the validity and reliability of the newly developed BERNCA instrument. Methods: Psychometric analysis was performed on data from 957 nurses in five Swiss acute care hospitals enrolled in a larger hospital organization study. An explanatory factor analysis with varimax rotation was used to investigate the instrument's internal structure, Spearman correlations were used to test relationships between implicit rationing and two related concepts, and Cronbach's alpha and interitem correlations were used to test the reliability of the scale. Results: Expert feedback confirmed that the BERNCA covered the implicit rationing of nursing care domain adequately and that its questions were fully comprehensible. The single-factor solution confirmed the instrument's unidimensional internal structure. A moderate to strong correlation in the expected direction was found between the BERNCA implicit rationing data and the quality of the nurse work environment as measured by the Nursing Work Index-Revised, particularly the perceived adequacy of nursing resources, although a significant but low correlation was also shown with patient-to-nurse ratios. Cronbach's alphas (.93) and interitem correlations indicated internal consistency and homogeneity. Discussion: Initial evidence of the validity and reliability of the BERNCA instrument was provided.

Abstract
Abstract
Computers and the Internet provide researchers with new options in surveying. When using electronic surveys, several practical and methodological issues need to be considered such as whether the majority of the surveyed population has Internet access and whether an e-mail or a Web-based survey is most appropriate. Other important considerations relate to Internet security issues and, in international research, the possibility of language barriers. Despite these challenges, electronic surveys offer a promising alternative to conventional mail surveys.
