Effects of self-management intervention on health outcomes of patients with heart failure: a systematic review of randomized controlled trials

Longitudinal validation of a tool for asthma self-monitoring

OBJECTIVES

To establish longitudinal validation of a new tool, the Asthma Symptom Tracker (AST). AST combines weekly use of the Asthma Control Test with a color-coded graph for visual trending.

METHODS

Prospective cohort study of children age 2 to 18 years admitted for asthma. Parents or children (n = 210) completed baseline AST assessments during hospitalization, then over 6 months after discharge. Concurrent with the first 5 AST assessments, the Asthma Control Questionnaire (ACQ) was administered for comparison.

RESULTS

Test-retest reliability (intraclass correlation) was moderate, with a small longitudinal variation of AST measurements within subjects during follow-ups. Internal consistency was strong at baseline (Cronbach's α 0.70) and during follow-ups (Cronbach's α 0.82-0.90). Criterion validity demonstrated a significant correlation between AST and ACQ scores at baseline (r = -0.80, P < .01) and during follow-ups (r = -0.64, -0.72, -0.63, and -0.69). The AST was responsive to change over time; an increased ACQ score by 1 point was associated with a decreased AST score by 2.65 points (P < .01) at baseline and 3.11 points (P < .01) during follow-ups. Discriminant validity demonstrated a strong association between decreased AST scores and increased oral corticosteroid use (odds ratio 1.13, 95% confidence interval, 1.10-1.16, P < .01) and increased unscheduled acute asthma visits (odds ratio 1.23, 95% confidence interval, 1.18-1.28, P < .01).

CONCLUSIONS

The AST is reliable, valid, and responsive to change over time, and can facilitate ongoing monitoring of asthma control and proactive medical decision-making in children.

Oral Chinese herbal medicine for improvement of quality of life in patients with chronic heart failure: a systematic review and meta-analysis

PURPOSE

Chronic heart failure (CHF) is not only a leading cause of death, hospitalization, and rehospitalization, but also significantly decreases quality of life (QoL). This study aims to evaluate published clinical trials of oral Chinese herbal medicine (OCHM) for improvement of QoL in patients with CHF that employ the Minnesota Living with Heart Failure Questionnaire (MLHFQ) score as an outcome measure.

METHODS

A systematic literature search was performed using five databases up to June 2013 to identify randomized control trials (RCTs). RCTs involving OCHM plus conventional medicine treatment (CMT) with or without blinding, compared with CMT with or without placebo, with MLHFQ score as an outcome measure were identified. The methodological quality of RCTs was assessed independently using the Cochrane Handbook for Systematic Review of Interventions. RevMan 5.2.5 and Stata 11.0 were used for data analysis.

RESULTS

Thirty-eight RCTs with a total of 3,170 participants were identified. The majority of the included trials were assessed to be of high clinical heterogeneity and poor methodological quality. The main results of meta-analysis showed improvement of total MLHFQ score when OCHM plus CMT compared with CMT with or without placebo [MD = -5.71 (-7.07, -4.36), p < 0.01].

CONCLUSIONS

There is some encouraging evidence of OCHM combined with CMT for the improvement of QoL in CHF patients. However, the evidence remains weak due to the small sample size, high clinical heterogeneity, and poor methodological quality of the included trials. Further, large sample size and well-designed trials are needed.

AUStralian Indigenous Chronic Disease Optimisation Study (AUSI-CDS) prospective observational cohort study to determine if an established chronic disease health care model can be used to deliver better heart failure care among remote Indigenous Australians: Proof of concept-study rationale and protocol

BACKGROUND

The congestive heart failure syndrome has increased to epidemic proportions and is cause for significant morbidity and mortality. Indigenous patients suffer a greater prevalence with greater severity. Upon diagnosis patients require regular follow-up with medical and allied health services. Patients are prescribed life saving, disease modifying and symptom relieving therapies. This can be an overwhelming experience for patients. To compound this, remoteness, differentials in conventional health care and services pose special problems for Indigenous clients in accessing care. Additional barriers of language, culture, socio-economic disadvantage, negative attitudes towards establishment, social stereotyping, stigma and discrimination act as barriers to improved care. Recent focus supported by clinical evidence support the role of chronic disease self-management programs. A patient focused, problem identification, goal setting and psychosocial modification based program should in principal highlight these issues and help tailor a patient focused comprehensive care plan to complement guideline based care. At present there are no Indigenous focused chronic disease self-management programs. There is a need for research on ways to provide chronic disease management to this group. We therefore designed a study to assess a model of patient focussed comprehensive care for Indigenous Australians with heart failure.

STUDY DESIGN

AUSI-CDS is a prospective, cohort, observational study to evaluate the efficacy of the standard "Flinders Program of Chronic Condition Management" for Indigenous patients with chronic heart failure. Eligible patients will be Indigenous, suffering from chronic heart failure, in the Northern Territory. The primary end-point is the satisfaction score based on the PACIC. The study will recruit 20 patients and is expected to last 12 months.

SUMMARY

The rationale and design of the AUSI-CDS using the Flinders Model is described.

Inpatient diabetes education is associated with less frequent hospital readmission among patients with poor glycemic control

OBJECTIVE

To explore the relationship between inpatient diabetes education (IDE) and hospital readmissions in patients with poorly controlled diabetes.

RESEARCH DESIGN AND METHODS

Patients with a discharge diagnosis of diabetes (ICD-9 code 250.x) and HbA1c>9% who were hospitalized between 2008 and 2010 were retrospectively identified. All-cause first readmissions were determined within 30 days and 180 days after discharge. IDE was conducted by a certified diabetes educator or trainee. Relationships between IDE and hospital readmission were analyzed with stepwise backward logistic regression models.

RESULTS

In all, 2,265 patients were included in the 30-day analysis and 2,069 patients were included in the 180-day analysis. Patients who received IDE had a lower frequency of readmission within 30 days than did those who did not (11 vs. 16%; P=0.0001). This relationship persisted after adjustment for sociodemographic and illness-related factors (odds ratio 0.66 [95% CI 0.51-0.85]; P=0.001). Medicaid insurance and longer stay were also independent predictors in this model. IDE was also associated with reduced readmissions within 180 days, although the relationship was attenuated. In the final 180-day model, no IDE, African American race, Medicaid or Medicare insurance, longer stay, and lower HbA1c were independently associated with increased hospital readmission. Further analysis determined that higher HbA1c was associated with lower frequency of readmission only among patients who received a diabetes education consult.

CONCLUSIONS

Formal IDE was independently associated with a lower frequency of all-cause hospital readmission within 30 days; this relationship was attenuated by 180 days. Prospective studies are needed to confirm this association.

Implementing shared medical appointments for heart failure patients in a community cardiology practice: a pilot study

OBJECTIVE

To examine patient and staff satisfaction, billing charges, and programmatic feasibility of shared medical appointments (SMA) in a nurse practitioner-managed heart failure (HF) clinic in a community cardiology practice.

METHODS

Twenty patients were scheduled among four SMAs for this pilot study. All aspects of a usual clinic appointment were utilized during the SMA, but an additional 20-minute teaching session was presented. All patients completed a satisfaction questionnaire. The office staff completed satisfaction questionnaires about the SMA. Billing charges, cancellations and missed appointments without cancellation for SMAs were compared to usual clinic appointment days.

RESULTS

Satisfaction was high among patients and office staff. Rates for no-shows were similar for SMAs versus usual appointments (15% versus 5.5%), but there were fewer cancellations among SMAs (0% versus 28%). This may be a reflection of the personalized appointment reminder calls that were made to the patients scheduled for SMAs. Billing charges were not significantly different for SMAs versus usual appointments.

CONCLUSION

SMAs are a feasible option in a community cardiology practice.

Prospective memory and chronic heart failure

Background

Patients with chronic heart failure (CHF) experience a number of debilitating symptoms, which impact on activities of daily living and result in poor quality of life. Prospective memory, which is defined as memory to carry out future intentions, has not been investigated in this group. However, emerging evidence suggests CHF patients have difficulties with cognitive processes related to prospective memory. Self-care, which partly relies on prospective memory, is essential in symptom management and preventing acute clinical deterioration. This study aims to measure prospective memory in CHF patients, and examine the relationship between prospective memory and CHF self-care.

Methods/Design

A comprehensive neuropsychological assessment will be conducted to assess a range of cognitive functions and psychopathology. The primary focus will be an assessment of prospective memory using a well-established behavioral measure; Virtual Week. Thirty CHF patients attending a nurse-led management program will be recruited from three hospital sites in Melbourne, Australia and their self-care behaviors will be assessed using the Self-care Chronic Heart Failure Index (SCHFI), a validated self-report tool. An additional 30 healthy controls, matched on age, gender, and IQ will be recruited from the general community.

Discussion

This is a group comparison study that will provide an evaluation of the prospective memory abilities of CHF patients. The findings of this research will provide insight into whether prospective memory may be hindering patients’ ability to perform adequate self-care.

Evaluation of a self-management patient education program for patients with chronic heart failure undergoing inpatient cardiac rehabilitation: study protocol of a cluster randomized controlled trial

Background

Chronic heart failure requires a complex treatment regimen on a life-long basis. Therefore, self-care/self-management is an essential part of successful treatment and comprehensive patient education is warranted. However, specific information on program features and educational strategies enhancing treatment success is lacking. This trial aims to evaluate a patient-oriented and theory-based self-management educational group program as compared to usual care education during inpatient cardiac rehabilitation in Germany.

Methods/Design

The study is a multicenter cluster randomized controlled trial in four cardiac rehabilitation clinics. Clusters are patient education groups that comprise HF patients recruited within 2 weeks after commencement of inpatient cardiac rehabilitation. Cluster randomization was chosen for pragmatic reasons, i.e. to ensure a sufficient number of eligible patients to build large-enough educational groups and to prevent contamination by interaction of patients from different treatment allocations during rehabilitation. Rehabilitants with chronic systolic heart failure (n = 540) will be consecutively recruited for the study at the beginning of inpatient rehabilitation. Data will be assessed at admission, at discharge and after 6 and 12 months using patient questionnaires. In the intervention condition, patients receive the new patient-oriented self-management educational program, whereas in the control condition, patients receive a short lecture-based educational program (usual care). The primary outcome is patients’ self-reported self-management competence. Secondary outcomes include behavioral determinants and self-management health behavior (symptom monitoring, physical activity, medication adherence), health-related quality of life, and treatment satisfaction. Treatment effects will be evaluated separately for each follow-up time point using multilevel regression analysis, and adjusting for baseline values.

Discussion

This study evaluates the effectiveness of a comprehensive self-management educational program by a cluster randomized trial within inpatient cardiac rehabilitation in Germany. Furthermore, subgroup-related treatment effects will be explored. Study results will contribute to a better understanding of both the effectiveness and mechanisms of a self-management group program as part of cardiac rehabilitation.
