    Cost-effectiveness of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease
    (2011) Reyes, C.; Silva, R.; Saldías, F.
    Patients with chronic respiratory disease are heavy users of health care and social services resources worldwide. Although the major goals of pulmonary rehabilitation programs are to reduce levels of morbidity and to improve activity as well as participation in patients with chronic respiratory disease, their role in the management of these patients must also be validated by cost-effectiveness. Pulmonary rehabilitation's role in decreasing utilization of health care resources is an important potential benefi t. Pulmonary rehabilitation is an effective intervention in patients disabled by chronic respiratory disease; however, there are relatively few studies that evaluate its effect on health care utilization. An 18-session, 6-week outpatient pulmonary rehabilitation program decreased inpatient hospital days and decreased the number of home visits when compared with standard medical management. A comprehensive costeffectivenes analysis of the addition of this multidisciplinary pulmonary rehabilitation program to standard care for patients with chronic disabling respiratory disease concluded that the program was cost-effective and produced cost per quality-adjusted-life-years (QALY) ratios within the bounds considered to be cost-effective and therefore likely to result in financial benefits to the health care system. Patients with COPD who receive an education intervention with supervision and support based on disease-specific self management principles have decreased hospital admissions, decreased emergency department visits, and reduced number of unscheduled physician visits. This approach of care through self-management strategies is of interest because it does not require specialized resources and could be implemented within normal health care practice. In a before-after designed study, a community-based, 18-session, comprehensive pulmonary rehabilitation program was associated with an average reduction of total costs of US$344 per person per year. This was associated with decreased health service utilization, reduced direct costs, and improved health status of patients with COPD, regardless of disease severity. In summary, pulmonary rehabilitation programs in COPD patients reduces hospital stay and hospital readmissions especially after exacerbations. Pulmonary rehabilitation programs significantly reduce the use of healthcare resources and are cost-effective.
