A matched-cohort study of selected clinical and utilization outcomes for an asthma care support program

The hepatitis C self-management programme: a randomized controlled trial

Chronic hepatitis C (HCV) infection afflicts millions of people worldwide. While antiviral treatments are effective for some patients, many either cannot or choose not to receive antiviral treatment. Education about behavioural changes like alcohol avoidance and symptom management, in contrast, is universally recommended, particularly in HCV-infected persons from disadvantaged groups where liver risk factors are most prevalent. Self-management interventions are one option for fostering improved HCV knowledge and health-related quality of life (HRQOL). One hundred and thirty-two patients with VA with HCV (mean age of 54.6, 95% men, 41% ethnic minority, 83% unmarried, 72% unemployed/disabled, 48% homeless in last 5 years) were randomized to either a 6-week self-management workshop or an information-only intervention. The weekly 2-h self-management sessions were based on cognitive-behavioural principles and were adapted from an existing self-management programme that has been efficacious with other chronic diseases. HCV-specific modules were added. Outcomes including HRQOL, HCV knowledge, self-efficacy, depression, energy and health distress were measured at baseline and 6 weeks later. Data were analysed using ANOVA. When compared to the information-only group, participants attending the self-management workshop improved more on HCV knowledge (P < 0.001), HCV self-efficacy (P = 0.011), and SF-36 energy/vitality (P = 0.040). Similar trends were found for SF-36 physical functioning (P = 0.055) and health distress (P = 0.055). Attending the self-management programme improved disease knowledge and HRQOL 6 weeks later in this disadvantaged population. The intervention can improve the health of people with hepatitis C, independent of antiviral therapy. Future research will study longer-term outcomes, effects on antiviral treatment and costs.

A systematic review of integrated use of disease-management interventions in asthma and COPD

BACKGROUND

The effectiveness of multiple interventions in asthma and chronic obstructive pulmonary disease (COPD) is unclear.

OBJECTIVE

To examine the effectiveness of multiple interventions as compared to single interventions or usual care on health outcomes and health care utilisation within the context of integrated disease management in asthma and COPD.

METHODS

MEDLINE and the Cochrane Library (1995-May 2008) were searched for controlled trials. Two reviewers independently extracted data and assessed study quality. Meta-analyses were performed on quality of life and health care utilisation data. Furthermore, the effects of multiple interventions versus single interventions and usual care were assessed qualitatively.

RESULTS

Of the 36 studies included, 17 targeted double interventions (patient-related and organisational interventions); 19 studies performed triple interventions (patient-related, professional-directed and organisational interventions). They were heterogeneous in terms of (combinations of) interventions, outcomes measured, study design and setting. Pooled data showed that studied disease management programmes significantly improved quality of life on several domains. Patients within triple intervention programmes had less chance of at least one hospital admission compared with usual care. No significant effects were found in number of emergency department visits. Qualitative analyses revealed positive trends on process improvements and satisfaction. Inconclusive results were reported on symptoms; no effects were found in lung function.

CONCLUSION

In spite of the heterogeneity of disease management studies in asthma and COPD care, this review showed promising improvements in quality of life and reductions in hospitalisations, especially for triple intervention programmes.

Evaluation of a medicaid asthma disease management program

This study evaluates 1-year outcomes of an asthma disease management program implemented in an Oregon Medicaid population. A non-randomized pre-post study, a matched case-control study, and a "programmatic effects" analysis were conducted. Compared to matched controls, the treatment cohort had significantly fewer emergency room visits per thousand (7 vs. 28, P < 0.001) and higher office visits per thousand (57 vs. 7, P < 0.0001) but no significant difference in hospital admission rates. The programmatic effects model identified the participants' initial severity levels and the number of various communications they received as the most important variables in explaining the change in asthma severity from baseline to 12 months. These findings are supportive of the DM design, which is to reduce acute services by improving coordination of care between patients and their providers. Additionally, it appears that there is a close association between the number of patient contacts and their subsequent change in health status.
