Risk Factors for Hospitalization Among Medicare Home Care Patients

This study determined factors associated with an increased risk of ending Medicare home health care because of hospitalization and examined specific types of and reasons for hospitalization. Sample members (N = 922) were followed from admission to discharge as they received home care from Ohio Medicare-certified home care agencies between December 1999 and March 2002. Potential patient-level risk factors were predisposing, enabling, or need variables, and an agency-level variable denoting hospital affiliation or free-standing status was examined as a second-level risk factor. Among those hospitalized (18.3%), more than 80.0% experienced emergency hospitalizations, mostly for acute exacerbations of chronic diseases. Statistically significant risk factors for hospitalization included dyspnea severity, functional disability level, skin or wound problems, diabetes, case mix score, and guarded rehabilitation prognosis. Home care agencies might reduce hospitalizations by using clinical prognosis as a key resource for team communication and by helping patients and families anticipate potential acute exacerbations of chronic diseases and manage these events at home.

Measuring disability in Medicare home care patients: application of Rasch modeling to the outcome and assessment information set.

Background. The Outcome and Assessment Information Set (OASIS) is the universal clinical assessment tool for adult nonmaternity patients receiving skilled care at home from Medicare-certified home health agencies in the United States. Anticipating increased use of OASIS data for research purposes, this article explored the usefulness of Rasch modeling to address disability measurement challenges presented by the unique response category structure of the seven activities of daily living (ADL) and eight instrumental ADL (IADL) items in the OASIS. Objectives. To illustrate how Rasch model statistics can be used to evaluate OASIS ADL and IADL item unidimensionality and model fit; to illustrate how Rasch modeling simultaneously estimates ADL and IADL item difficulty, thresholds between item response categories, and person disability; and to compare Rasch estimates of item difficulty and person disability scores to estimates based on more conventional Likert scoring techniques. Subjects. Medicare-eligible home health care patients (n = 583) served by one of 12 home care agencies in Ohio between November 1999 and September 2000. Measures. ADL and IADL items were measured three ways: according to the original OASIS scoring (raw Likert); transformed raw Likert scores accounting for the nonuniform item structure (corrected Likert); and Rasch Partial Credit model scores. Results. The items bathing and telephone use showed evidence of unexpected response patterns; recoding of these items was necessary for good Rasch model fit. Partial Credit model results revealed that interval distances between response categories varied widely across the 15 ADL and IADL items. When ADL and IADL items were ranked by level of difficulty, results were similar between Rasch and corrected Likert measurement approaches; however, corrected Likert person scores were found to be nonlinear at highest and lowest disability levels when plotted against Rasch person scores. Conclusions. Rasch modeling can help improve the precision of disability measurement in Medicare home care patients when using ADL and IADL items from the OASIS instrument.

Transformational leadership practices of chief nursing officers in Magnet® organizations.

Objective: This study describes the transformational leadership practices of Magnet® chief nursing officers (CNOs). Background: It is believed that transformational leadership practices influence quality and are integral to Magnet designation. Methods: E-mail surveys of 384 Magnet CNOs were conducted in 2011 using the leadership practices inventory (LPI). Results: Enabling others to act and modeling the way are top practices of Magnet CNOs. Those 60 years or older and those with doctorate degrees scored significantly higher in inspiring a shared vision and challenging the process. There was a significant positive relationship between total years as a CNO and inspiring a shared vision and between total scores on the LPI and number of beds in the organization. Conclusions: As CNOs gain experience and education, they exhibit more transformational leadership characteristics. Magnet organizations should take steps to retain CNOs and support their development and advancement.

Risk Factors for Hospitalization in a National Sample of Medicare Home Health Care Patients

Acute care hospitalization during or immediately following a Medicare home health care (HHC) episode is a major adverse outcome, but little has been published about HHC patient-level risk factors for hospitalization. The authors determined risk factors at HHC admission associated with subsequent acute care hospitalization in a nationally representative Medicare patient sample (N = 374,123). Hospitalization was measured using Medicare claims data; risk factors were measured using Outcome Assessment and Information Set data. Seventeen percent of sample members were hospitalized. Multivariate logistic regression analysis found that the most influential risk factors (all p < .001) were skin wound as primary HHC diagnosis, clinician-judged guarded rehabilitation prognosis, congestive heart failure as primary HHC diagnosis, presence of depressive symptoms, dyspnea severity, and Black, compared to White. HHC initiatives that minimize chronic condition exacerbations and actively treat depressive symptoms might help reduce Medicare patient hospitalizations. Unmeasured reasons for higher hospitalization rates among Black HHC patients deserve further investigation.

Validity Testing the Outcomes and Assessment Information Set (OASIS)

This study evaluated the criterion validity of the Outcome and Assessment Instrument Set (OASIS) items that measure activities of daily living (ADLs), instrumental activities of daily living (IADLs), cognitive functioning, and depression. A convenience sample of patients (n = 203) from five home care agencies participated in the study. Patient OASIS items were compared to data collected using gold standard instruments. Correlations range from .44 to .69 for ADLs and .20 to .68 for IADLs. A correlation of .62 was found for cognitive functioning while correlations for depressive symptoms are .36 and .26. OASIS ADLs and cognitive status items are sufficiently valid, but the OASIS depression item is not sufficiently sensitive to the prevalence of these conditions.

Home health services research.

This chapter reviews 69 published research reports of home health care from a health services perspective by nurse researchers and researchers from other disciplines. Reports were identified through searches of the National Library of Medicine (MEDLINE), and the Cumulative Index to Nursing and Allied Health Literature and Social Sciences Citation Index using the following search terms: home health care, health services research, and elders. Within the major areas identified, the following additional terms were specified: resource use and outcomes. Reports were included if published between 1995 and 2001, used samples age 65 and older, performed in the U.S., and published in English. Studies of all types were included. The key findings follow: (a) Most studies were atheoretical. If a theoretical model was used, it was most often the Andersen Behavioral Model, (b) Few conclusions can be drawn about resource use—increasing age and higher severity of health related problems are associated with higher numbers of home visits. The variety of measures of resource use and the study approaches (large national data sets versus single or several agency samples) limits the ability to draw conclusions on resource use. (c) There is a growing body of evidence on rehospitalization of home health care patients which indicates rehospitalization is prevalent but largely not predictable, (d) Patient outcomes research is inconclusive at this point, primarily because there are few studies that examine patient outcomes using a consistent set of measures. The main recommendations are: to study rehospitalization using a more profile-based approach to determine visit patterns that may be effective, to further specify the kinds of outcomes that may be achieved as a result of home health care and which patients might be expected to achieve positive outcomes, and to examine the integration of home health care with the broader community-based services.

The Rural Nurse Work Environment and Structural Empowerment

Rural health care organizations struggle to attract and retain nurses, yet much of the research has focused on characteristics of the nurse work environment or empowerment in urban hospitals. The purpose of this study was to examine the nurse work environment in rural areas across settings by describing the relationship between structural empowerment and characteristics of the nurse work environment. Nurses ( N = 97) working in home care agencies and hospitals were surveyed. Significant differences were found between the groups, with home care nurses having significantly higher empowerment scores than medical/surgical nurses. A strong correlation was found between characteristics of the nurse work environment and empowerment. Policy makers are using evidence to guide development of policies, but much of the research has been conducted in urban hospital settings. This study begins to provide evidence that differences exist between urban and rural areas and between practice settings.

Exercise of Autonomous Home Care Practice: The Relationship with Nurse Characteristics

This study examined how the value of autonomy is reflected in home healthcare agencies’ practice models and how staff registered nurse (RN) characteristics (education, experience, certification) relate to the RNs’ perception of their ability to exercise autonomous practice: control over practice decisions (clinical autonomy) and control over practice setting decisions (organizational autonomy). RNs (N = 82) from 11 agencies were found to have more control over practice decisions than practice setting decisions. No significant relationship was found between RN characteristics of education, RN experience, home healthcare experience, and specialty certification.

An examination of the most frequent adverse events in home care agencies.

While home care agencies and surveyors can access individual agency adverse event reports, there has been little reported on common profiles across agencies. This study examined adverse event reports from participating Ohio and Michigan agencies to provide descriptive information regarding the most frequent adverse events. Additionally, a discussion of the potential impact and uses of these reports is presented.

Telehealth: Is Your Staff Ready To Implement? A Descriptive Exploratory Study of Readiness for this Technology in Home Health Care

Telehealth is defined in this study as remote telemonitoring in the patient’s home using a device to capture vital signs and related healthcare information, which is transmitted over the phone line. Telehealth, used to support home visits, is one solution to position home health agencies for success in the pay-for-performance model. Staff readiness to implement remote monitoring impacts device implementation and success of the telehealth program. The authors of this study evaluated nurse readiness for telehealth implementation within the home health agencies of one health system providing insight into the implementation plan.
