PULMONARY REHABILITATION IN THE ELDERLY PATIENT

Use of physical and occupational therapy by Medicare beneficiaries within five conditions: 1994-2001

OBJECTIVE

To examine the use of physical therapy and occupational therapy among Medicare beneficiaries nationwide before and after the 1997 Balanced Budget Act, which introduced prospective payment for rehabilitation services.

DESIGN

We analyzed responses from the longitudinal Medicare Current Beneficiary Survey, merged with Medicare claims, to track physical therapy and occupational therapy rates and intensity (units of service) from 1994 through 2001. This observational study focused on elderly and disabled Medicare beneficiaries within five conditions: stroke, acute myocardial infarction, chronic obstructive pulmonary disease, arthritis, and lower-limb mobility problems. We used cubic smoothing spline functions to describe trends in service intensity over time and generalized estimating equations to assess changes in service intensity.

RESULTS

Controlling for demographic characteristics, adjusted mean level of physical therapy and occupational therapy intensity rose significantly between 1994 and 2001 for all five conditions. Service intensity leveled off in 1999 for occupational therapy and 2000 for physical therapy. With few exceptions, physical therapy and occupational therapy intensity was not significantly associated with patients' demographic characteristics.

CONCLUSIONS

Medicare beneficiaries with conditions that can potentially benefit from physical therapy or occupational therapy or both continued to get these services at similar-and sometimes increasing-intensity during years after passage of the Balanced Budget Act.

Pulmonary rehabilitation for chronic obstructive pulmonary disease

BACKGROUND

The widespread application of pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) should be preceded by demonstrable improvements in function attributable to the programs. This review updates that reported in 2001.

OBJECTIVES

To determine the impact of rehabilitation on health-related quality of life (QoL) and exercise capacity in patients with COPD.

SEARCH STRATEGY

We identified additional RCTs from the Cochrane Airways Group Specialised Register. Searches were current as of July 2004.

SELECTION CRITERIA

We selected RCTs of rehabilitation in patients with COPD in which quality of life (QoL) and/or functional (FEC) or maximal (MEC) exercise capacity were measured. Rehabilitation was defined as exercise training for at least four weeks with or without education and/or psychological support. Control groups received conventional community care without rehabilitation.

DATA COLLECTION AND ANALYSIS

We calculated weighted mean differences (WMD) using a random-effects model. We requested missing data from the authors of the primary study.

MAIN RESULTS

We included the 23 randomized controlled trials (RCTs) in the 2001 Cochrane review. Eight additional RCTs (for a total of 31) met the inclusion criteria. We found statistically significant improvements for all the outcomes. In four important domains of QoL (Chronic Respiratory Questionnaire scores for Dyspnea, Fatigue, Emotional function and Mastery), the effect was larger than the minimal clinically important difference of 0.5 units (for example: Dyspnoea score: WMD 1.0 units; 95% confidence interval: 0.8 to 1.3 units; n = 12 trials). Statistically significant improvements were noted in two of the three domains of the St. Georges Respiratory Questionnaire. For FEC and MEC, the effect was small and slightly below the threshold of clinical significance for the six-minute walking distance (WMD: 48 meters; 95% CI: 32 to 65; n = 16 trials).

AUTHORS' CONCLUSIONS

Rehabilitation relieves dyspnea and fatigue, improves emotional function and enhances patients' sense of control over their condition. These improvements are moderately large and clinically significant. Rehabilitation forms an important component of the management of COPD.

The functional impact of an individualized, graded, outpatient pulmonary rehabilitation in end-stage chronic obstructive pulmonary disease

OBJECTIVE

To evaluate the functional impact of an individualized outpatient pulmonary rehabilitation program in end-stage chronic obstructive pulmonary disease (COPD).

METHODS

Patients with end-stage COPD were admitted into a 6-week comprehensive outpatient pulmonary rehabilitation program that was "packaged" for each patient. We compared spirometric parameters, exercise tolerance, level of breathlessness, and intensity of work before and after rehabilitation.

RESULTS

Of 45 eligible patients, only 14 consented to participate in the study. All 14 patients had forced expiratory volume in 1 second <35% of predicted, and 10 patients (72%) had a 6-minute walk test <180 m. The level of breathlessness was between 7 (moderate to severely breathless) and 10 (maximally breathless) on the Visual Analogue Scale in all patients. After the program, there was significant improvement in the FEV 1 P = 0.04), forced vital capacity P = 0.0045), 6-minute walk test P = 0.00047), and shuttle-walk test (9 of 14 patients). All patients had some improvement in level of dyspnea.

CONCLUSIONS

Individualized outpatient pulmonary rehabilitation in end-stage COPD can produce a measurable improvement in spirometry and exercise tolerance with a favorable impact on the level of physical activity.

Pulmonary rehabilitation for chronic obstructive pulmonary disease

BACKGROUND

The widespread application pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) should be preceded by demonstrable improvements in function attributable to the programs. This review updates that reported by Lacasse et al Lancet 1996; 748:1115-1119.

OBJECTIVES

To determine the impact of rehabilitation on health-related quality of life (QoL) and exercise capacity in patients with COPD.

SEARCH STRATEGY

The 14 randomized controlled trials (RCTs) included in the original meta-analysis were included. Additional RCTs were identified from the Cochrane Airways Group's registry of COPD RCTs using the strategy: [exp, lung diseases, obstructive] and [exp, rehabilitation or exp, exercise therapy] and [research design or longitudinal studies or evaluation study or randomized controlled trial]. Abstracts presented at American Thoracic Society 1980-2000, American College of Chest Physicians 1980-2000 and European Respiratory Society 1987-2000 were also searched.

SELECTION CRITERIA

RCTs of rehabilitation in patients with COPD in which quality of life (QoL) and/or functional (FEC) or maximal (MEC) exercise capacity were measured. Rehabilitation was defined as exercise training for at least 4 weeks with or without education and/or psychological support. Control groups received conventional community care without rehabilitation.

DATA COLLECTION AND ANALYSIS

Weighted mean differences (WMD) were calculated using a random-effects model. Missing data from the primary study reports were requested from the authors.

MAIN RESULTS

23 RCTs met the inclusion criteria. Statistically significant improvements were found for all the outcomes. In three important domains of QoL (Chronic Respiratory Questionnaire scores for Dyspnea, Fatigue and Mastery), the effect was larger than the minimal clinically important difference of 0.5 units using this instrument. For example Dyspnoea score: WMD 0.98 units, 95% Confidence Interval (95% CI) 0.74 - 1.22 units; n=9 trials. For FEC and MEC, the effect was small and a little below the threshold of clinical significance for the 6- minute walking distance: WMD 49 m, 95% CI: 26 - 72 m; n=10 trials.

REVIEWER'S CONCLUSIONS

Rehabilitation relieves dyspnea and fatigue and enhances patients' sense of control over their condition. These improvements are moderately large and clinically significant. The average improvement in exercise capacity was modest. Rehabilitation forms an important component of the management of COPD.

Bedingungen der Erhaltung und Förderung von Selbständigkeit im höheren Lebensalter (SIMA) Teil XIII: Verlaufsanalyse der Gesundheit *Das interdisziplinäre Forschungsprojekt Bedingungen der Erhaltung und Förderung von Selbständigkeit im höheren Lebensalter (SIMA) des Instituts für Psychogerontologie der Friedrich-Alexander Universität Erlangen-Nürnberg wird geleitet von Prof. Dr. W. D. Oswald und Dr. R. Rupprecht, in Zusammenarbeit mit Prof. Dr. E. Lang (Carl Korth Institut), Prof. Dr. H. Baumann (Institut für Sportwissenschaft), Prof. Dr. M. Stosberg (Sozialwissenschaftliches Forschungszentrum), Dr. K. C. Steinwachs (Klinikum am Europakanal und IPG) und der Interdisziplinären Arbeitsgemeinschaft für Angewandte Gerontologie e. V. Das SIMA-Projekt wird mit Mitteln des Bundesministeriums für Familie, Senioren, Frauen und Jugend (GZ 303-1722-102/23) gefördert. Die Verantwortung für den Inhalt dieser Veröffentlichung liegt bei den Autoren

Zusammenfassung: Zwischen 1991 und 1996 wurden die langfristigen Effekte der SIMA-Trainings auf den Gesundheitsstatus der Teilnehmer im Alter zwischen 75 und 93 Jahren (mittleres Alter 79.5 Jahre, 1991 N = 375) untersucht. Die Trainings wurden zwischen 1991 und 1992 in fünf voneinander unabhängigen Gruppen durchgeführt. Eine weitere Gruppe der Teilnehmer bildete die Kontrollgruppe. Die Auswertung erfolgte mit der Stichprobe jeweils aller zu einem Zeitpunkt untersuchten Teilnehmer und mit der Stichprobe der 1996 verbliebenen Teilnehmer. Der Gesundheitsstatus wurde über einen gewichteten Organfunktionsindex, den Medikamentenkonsum und die subjektive Gesundheit operationalisiert. Der gewichtete Organfunktionsindex faßt Werte aus verschiedenen Funktionsbereichen zusammen. In der Verlaufsanalyse zeigte sich, daß insbesondere die Teilnehmer eines kombinierten Gedächtnis- und Psychomotoriktrainings langfristig einen signifikant höheren Gesundheitsstatus als die Teilnehmer in der Kontrollgruppe erreichten. Diese positiven Trainingseffekte waren vor allem in den Funktionsbereichen Kreislauf - Gefäße, Bewegungsapparat und Stoffwechsel zu beobachten. Positive Ausgangswertunterschiede zugunsten der Gruppen mit einem psychomotorischen Training wurden dagegen hauptsächlich bei der subjektiven Gesundheit nachgewiesen. Frauen erreichten gegenüber Männern bessere Werte in den Funktionsbereichen Sensorium und Urogenitalsystem. Geschlechtsspezifische Wechselwirkungen der Trainings wurden nicht nachgewiesen. Die Ergebnisse zeigen, daß ein kombinierter Trainingsansatz auch im hohen Lebensalter positive Langzeiteffekte auf den Gesundheitsstatus bewirken kann.

Chronic bronchitis and chronic obstructive pulmonary disease: Finnish National Guidelines for Prevention and Treatment 1998-2007

1. A national recommendation for the promotion of prevention, treatment and rehabilitation in relation to chronic bronchitis and COPD from 1998 to 2007 has been prepared on the basis of extensive collaboration by order of the Ministry of Social Affairs and Health. The Programme needs to be revised as necessary, because of rapid developments in medical knowledge, and in drug therapy in particular. 2. COPD is a disease characterized by slowly progressing, irreversible airways obstruction. Over 5% of the population suffer from symptomatic forms of the disease. It is estimated that a further 5% of the population may suffer from latent COPD. Most patients (75%) suffer from mild forms of the disease. The disease is often preceded by chronic bronchitis. A total of 400,000 Finns suffer from chronic bronchitis or COPD. Occurrence of these diseases in future will be particularly affected by decreased smoking by men, increased smoking by the young and by women, and aging of the population. 3. In 1997, the annual treatment costs of chronic bronchitis and COPD were estimated to be FIM 1.5 thousand million, total costs FIM 5 thousand million. Without intensification of measures to prevent and treat the diseases, costs will rise significantly. Costs arising from severe COPD (5% of patients with COPD) account for roughly 65% of costs overall and are primarily related to hospitalizations. 4. The goals of the Programme for the Prevention and Treatment of Chronic Bronchitis and COPD are as follows: (a) to decrease the incidence of chronic bronchitis; (b) to ensure that as many patients as possible with chronic bronchitis recover; (c) to maintain capacity for work and functional capacity of patients with COPD; (d) to reduce the percentage of patients with moderate to severe COPD; (e) to decrease the number of hospitalization days of COPD patients by 25% overall; and (f) to decrease annual costs per patient. 5. The following means are suggested for achieving the goals: (a) reduction in smoking; (b) reduction in work-related and outdoor air pollutants and improvement of quality of indoor air; (c) enhancement of knowledge about risk factors and treatment of the diseases is in key groups; (d) promotion of early diagnosis and active treatment, in smokers in particular; (e) improvement of guided self-care; (f) early commencement of rehabilitation, individual planning and implementation, primarily as an element in treatment; and (g) encouragement of scientific research. 6. COPD and exacerbation of its symptoms can be prevented through choices relating to life habits, such as not smoking, maintaining good general condition, and protection against exposure to dusts. The Programme gives examples of such measures and appeals to various authorities and voluntary organizations to increase their cooperation. Preventive methods should be individualized, and based on due consideration. 7. Chronic bronchitis and COPD should be diagnosed at early stages, and treated appropriately from the outset. Treatment consists of: (a) treatment according to causes, such as stopping smoking and work hygiene; (b) early rehabilitation such as patient education and guided self-care: (c) drug therapy; (d) hospital treatment; and (e) rehabilitation. 8. The hierarchy of referrals in the treatment of COPD should be revised to accord a greater role to the primary health care sector. Good exchanges of information and cooperation between the primary health care and specialized medical care sectors will all be necessary if this hierarchial model is to have the desired effect. 9. Hospital districts and health centres should ensure that different levels of the health-care system are capable of fulfilling the tasks assigned to them appropriately. One specialist in each hospital district should be given charge of prevention and assembly of know-how relating to treatment, and of quality of treatment at regional level. (ABSTRACT TRUNCATED)

Pulmonary rehabilitation improves exercise capacity in older elderly patients with COPD

Pulmonary rehabilitation has been shown to improve exercise capacity in patients with COPD. It has been suggested that this improvement applies to all age groups; however, to our knowledge, the effects of pulmonary rehabilitation on older elderly patients (> or = 75 years of age) have not been studied. We compared changes in 12-min walking distance (12MD) and self-assessment scores in 47 older elderly patients with moderate to severe COPD who completed inpatient or outpatient pulmonary rehabilitation with those achieved by 87 younger patients who participated in the same programs from 1987 to 1992. There were 28 older elderly individuals (mean +/- SEM, 78 +/- 1 years) in the outpatient group and 56 younger patients (64 +/- 1 years). There were no differences between older and younger outpatients with respect to FEV1, FEV1/FVC, maximum inspiratory pressure (PImax), baseline 12MD, or baseline self-assessment score. After outpatient pulmonary rehabilitation, 12MD and self-assessment scores improved significantly in both groups. Inpatients included 19 older elderly individuals (81 +/- 1 years) who were also similar to the 31 younger inpatients (64 +/- 1 years) in FEV1, FEV1/FVC, PImax, and baseline self-assessment score, but they tended to be more limited in terms of baseline 12MD (p = 0.09). After inpatient pulmonary rehabilitation, significant improvements in 12MD and self-assessment were seen in both groups. We conclude that comprehensive outpatient and inpatient pulmonary rehabilitation programs are as beneficial in older elderly patients with COPD as they are in younger patients with similar lung function abnormalities. Patients 75 years of age or older should be considered for comprehensive pulmonary rehabilitation.
