Clinical pathways: improving patient education and influencing readmission rates

A study on investigating unplanned readmission patterns

AIM

To explain frequent hospital readmissions, this study aimed to determine whether definable subtypes exist within a cohort of subjects with chronic illness with regard to factors associated with a patient's readmission patterns and to compare whether these factors vary between subjects in groups with different profiles.

RESEARCH METHOD

A descriptive correlational survey was conducted and data were collected by using a structured questionnaire. Seventy-four readmitted subjects were recruited in three general hospitals in Hong Kong.

OUTCOME MEASURES

Five outcome variables were employed in the study: predisposing characteristic, need factors, health behaviour, health status or outcomes and enabling resources.

RESULTS

A cluster analysis yielded two clusters. Each cluster represented a different profile of the sample on patient use of healthcare services. Cluster A consisted of 41.9% (n = 31) and Cluster B consisted of 58.1% (n = 43) of the patients. Cluster A patients, more of whom were male, were younger, more educated, had higher activities of daily living scores and fewer of them had received community nurse services than patients of Cluster B. Cluster A patients (32.3%) had more than one readmission record within 28 days than Cluster B patients (9.3%, p = 0.017).

CONCLUSION

Our study shows that community nurse services can reduce the rate at which they are readmitted a second time. However, such services may have a positive effect only on a group of patients whose profile is similar to the patients in Cluster B and not for patients such as those in Cluster A. A clear profile may help healthcare policy makers make appropriate strategies to target a specific group of patients to reduce their readmission rates.

RELEVANCE TO CLINICAL PRACTICE

The identification of risk for future healthcare use could enable better targeting of interventional strategies within these groups. The results of this study might provide hospital managers with a model to design specified interventions to reduce unplanned hospital readmissions for each profile group.

Are the outcomes of clinical pathways evidence-based? A critical appraisal of clinical pathway evaluation research

AIM AND OBJECTIVE

To evaluate the validity of study outcomes of published papers that report the effects of clinical pathways (CP).

METHOD

Systematic review based on two search strategies, including searching Medline, CINAHL, Embase, Psychinfo and Picarta from 1995 till 2005 and ISI Web of Knowledge SM. We included randomized controlled or quasi-experimental studies evaluating the efficacy of clinical pathway application. Assessment of the methodological quality of the studies included randomization, power analysis, selection bias, validity of outcome indicators, appropriateness of statistical tests, direct (matching) and indirect (statistical) control for confounders. Outcomes included length of stay, costs, readmission rate and complications. Two reviewers independently assessed the methodological quality of the selected papers and recorded the findings with an evaluation tool developed from a set of items for quality assessment derived from the Cochrane Library and other publications.

RESULTS

The study sample comprised of 115 publications. A total of 91.3% of the studies comprised of retrospective studies and 8.7% were randomized controlled studies. Using a quality-scoring assessment tool, 33% of the papers were classified as of good quality, whereas 67% were classified as of low quality. Of the studies, 10.4% controlled for confounding by matching and 59.1% adopted parametric statistical tests without testing variables on normal distribution. Differences in outcomes were not always statistically tested.

CONCLUSION

Readers should be cautious when interpreting the results of clinical pathway evaluation studies because of the confounding factors and sources of contamination affecting the evidence-based validity of the outcomes.

Factors contributing to hospital readmission in a Hong Kong regional hospital: a case-controlled study

BACKGROUND

As many as 50% of total hospital admissions are readmissions. Because the factors contributing to hospital readmission are multiple, and research findings are not conclusive, it is important for clinicians to gain an understanding of the key factors that contribute to readmission.

OBJECTIVES

This study explores the factors contributing to hospital readmission and derives an explanatory model that can best identify characteristics of patients at high risk for hospital readmission.

METHODS

This research was a case-controlled study with readmitted patients (n = 168) as the readmitted group and non-readmitted patients (n = 98) as the control group. The variables included demographic data, health assessment data, medical diagnosis, frequency of admissions, severity of illness, intensity of service and improvement of condition. The study sample was also interviewed to explore the patients' views on their repeated hospitalization.

RESULTS

In the bivariate analysis significant differences between the study and control groups were multiple and generally consistent with findings in other studies. Using multiple logistic regression, however, the final model shows that only three factors best predict readmissions: frequency (3-4 times) of readmissions (OR = 9.96, p < .0001) and frequency (more than 5 times) of readmissions (OR = 15.73, p < .0001), financial assistance (OR = 5.03, p < .001), and severity of illness (OR = 3.12, p < .01). Our interview data suggest that the readmitted patients required assistance to accomplish daily living activities upon discharge and often returned to the hospital for the same health reason.

CONCLUSION

The study findings suggest that patients who are frequently readmitted to the hospital are severely ill; are on public assistance; and may need special attention when discharged in order to attenuate repeated hospital readmission.

The role of the nurse in urinary incontinence

Specialist nursing is dynamic and needs to be sensitive, flexible and responsive to changes in care delivery. Clinical, educational, managerial, audit and research activities are all integral to the role of the specialist continence nurse. Nurse specialists need to be careful that they do not de-skill the role of more generalist nurses, but rather enhance their contribution to continence care. They also need to work collaboratively with their Specialist Continence Physiotherapist colleagues. There is evidence that care in the community setting and on ward areas is sub-optimal. Recent audit activities have shown that nurses feel comfortable about assessing the person with continence problems but less certain about treatment. One way to address this imbalance is through the use of care pathways, examples of which are illustrated.

Description of a multihospital process to develop a care path for the child with acute lymphoblastic leukemia

This article describes the National Association of Children's Hospitals and Related Institutions (NACHRI) collaborative group process used to create a multihospital care path for the child with acute lymphoblastic leukemia (ALL), and presents strategies for implementation and future direction. Although most children in the United States with cancer are treated according to National Cancer Institute-sponsored comprehensive protocols, there is a wide variation in the implementation of protocols by physicians and hospitals. The development of this care path was based on evidence from the literature, review of practice patterns, expert opinion, and group participant consensus building. The resulting 4-day care path was organized into six categories of care (e.g., assessment practices, diagnostic tests, teaching, and discharge planning). Discharge criteria are stated at the beginning of the care path to emphasize the planning process immediately on admission. Clinical outcomes, skill and knowledge outcomes for the parent and child, and home assessment considerations are also included. Strategies to create change and gain support of various stakeholders toward implementation of the care path are presented. The strength of the resulting care path is possible in large part because the multihospital group process brought professionals from around the country together to discuss, analyze, and reach consensus on the practices related to the child with ALL. The group process enabled the development of a care path that goes beyond a traditional care path developed by a single institution.
