Functional status and survival following pulmonary rehabilitation.

BACKGROUND: Functional exercise capacity has been shown to be a strong predictor of survival following pulmonary rehabilitation. This study evaluated whether questionnaire-rated functional status is also predictive of survival. PATIENTS AND METHODS: Following pulmonary rehabilitation, patients with advanced chronic lung disease were evaluated for survival, 6-min walk distance, and questionnaire-rated functional status. The latter was measured using the pulmonary functional status scale, which has subscores of functional activities, psychological status, and dyspnea. Information on survival was available on 149 patients. RESULTS: The mean age was 69 years, and 45% of patients were male. Eighty-nine percent had a diagnosis of COPD, and their FEV(1) was 37+/-18% of predicted. Ninety-one (61%) were married. The 3-year survival for the group was 85%. Age, gender, body mass index, and primary diagnosis were not related to survival. Variables strongly associated with increased survival following pulmonary rehabilitation included a higher postrehabilitation Functional Activities score, a longer postrehabilitation 6-min walk distance, and being married (vs widowed, single, or divorced). Disease severity variables associated with survival included an initial referral to outpatient pulmonary rehabilitation, no supplemental oxygen requirement, and a higher percent-predicted FEV(1). CONCLUSION: Indicators of functional status are strong predictors of survival in patients with advanced lung disease.

Functional status in pulmonary rehabilitation participants.

PURPOSE: This study examined functional status abnormalities in pulmonary rehabilitation patients, its responsiveness to pulmonary rehabilitation intervention, and its relationship to patient characteristics and traditional measures of disease severity. METHODS: One hundred sixty-four men and women age 69 years (SD +/- 8), who participated in 1 of 10 pulmonary rehabilitation programs in Connecticut, were studied pre- and postrehabilitation with the following outcome measures: (1) the 6-minute walk distance, (2) the Pulmonary Functional Status Scale (PFSS), and (3) in a subset of 60 subjects, health-related quality of life was measured using the Chronic Respiratory Disease Questionnaire (CRDQ). Patient characteristics were compared to baseline values of these measures using Spearman correlations and Wilcoxon Rank Sum tests, whereas pre- to post-changes in outcome measures were evaluated using Wilcoxon signed-ranks tests. Effect size, representing a standardized measure of change, was calculated for the PFSS. RESULTS: The mean FEV1 was 0.95 +/- 0.50 liters (38 +/- 18% predicted). Rehabilitation resulted in significant increases in the 6-minute walk distance (24%, P < 0.001, the total PFSS scores [13%, P < 0.001, effect size 1.0]) and the total CRDQ (18% P < 0.001). The prerehabilitation function subscore and total PFSS score correlated strongly with the 6-minute walk distance (r = 0.76, 0.73; P < 0.001) and to a lesser degree with the FEV1 (r = 0.31, 0.33; P < 0.001). Males scored higher baseline scores in several PFSS subscales, the total PFSS score, and the 6-minute walk distance; females showed more improvement in some of the PFSS scores. CONCLUSION: The 6-minute walk distance, the PFSS, and CRDQ all improved significantly with rehabilitation. Functional status, as measured by the PFSS is very strongly correlated with the 6-minute walk. Gender differences in the timed walk distance and functional status highlight the need to study this variable more thoroughly.

Overview of lung disease: screening and prevention.

The purpose of this article is to review respiratory assessment, common pulmonary diseases, and their risk factors and diagnosis. Prevention and screening are discussed as they relate to chronic obstructive pulmonary disease, asthma including occupational asthma, and interstitial lung disease.

Respi-Care. An innovative home care program for the patient with chronic obstructive pulmonary disease.

The purpose of the present study was to evaluate the effectiveness of a hospital-based home care program for a group of patients with severe COPD. Respi-Care was a multidisciplinary home care program administered by Norwalk Hospital in cooperation with the public health nursing departments of the city of Norwalk and the town of Wilton, Conn. The overall goal of Respi-Care was to provide more comprehensive home care services to patients previously requiring frequent hospitalizations by combining the advantages of hospital resources and community agencies through a unique cooperative effort. Preprogram and on-program data were collected on the following variables for the 48 months of Respi-Care operation: hospitalizations; hospital days; emergency room visits; home care services; and the costs of these services. Costs of operating the Respi-Care program were included in on-program data. Seventeen subjects completed 320.5 months on Respi-Care. Each subject was matched to an equal length of time prior to entering the program, for a total of 641 months analyzed. There were 88 preprogram hospitalizations for the group; hospitalizations while participating in Respi-Care dropped to 53 (p = 0.022; paired t statistics). On-program hospital days showed a significant decrease, from 1,181 preprogram days to 667 on-program days (p = 0.024). Emergency room visits decreased from 105 before the program to 64 during the program (p = 0.017). Costs of care also decreased. Costs for hospitalizations, emergency room visits, and home care fell from $908,031 to $802,999, resulting in a $105,032 savings or $328 per patient per month.(ABSTRACT TRUNCATED AT 250 WORDS)

Sexual dysfunction and COPD: problems and management.

Engaging in sexual activity is a common difficulty for persons with chronic obstructive pulmonary disease (COPD). Misconceptions, ignorance, medications and poor physical or mental health, all factors common to this population, contribute to sexual dysfunction. The nurse practitioner can help patients with COPD deal with the problems of sexual function by assessing possible contributing factors, teaching ways to minimize these factors and to increase exercise tolerance, and encouraging other expressions of love, affection and intimacy.
