Pulmonary Rehabilitation Improves Self-Management Ability in Subjects With Obstructive Lung Disease.

BACKGROUND: Optimizing self-management is a key element in multidisciplinary pulmonary rehabilitation in patients with asthma or COPD. This observational study aimed to investigate the changes in self-management following pulmonary rehabilitation in subjects with chronic lung disease. METHODS: Data were prospectively and routinely gathered at initial assessment and discharge in subjects taking part in a 12-week multidisciplinary out-patient pulmonary rehabilitation program. Measures of self-management included the Patient Activation Measure (PAM), the Health Education Impact Questionnaire (HEIQ) (8 subscales), a Self-Efficacy Questionnaire (2 subscales), the Lung Information Needs Questionnaire (LINQ), and the Health Literacy Questionnaire (HLQ) (9 subscales). Mean differences with 95% CI and effect sizes were computed. RESULTS: A total of 70 subjects (62.9% women) were included, with a median age of 63.5 y; most of the subjects had been diagnosed with COPD (77%). Between admission and discharge, all measures of self-management increased significantly except for the HEIQ subscales of constructive attitudes and approaches, social integration and support, and health services navigation; and the HLQ subscale of social support for health. The largest improvements (effect size > 0.55) were seen for the PAM (0.57); the HEIQ subscales of health-directed behavior (0.71), self-monitoring and insight (0.62), and skill and technique acquisition (1.00); the HLQ subscales of having sufficient information to manage my health (1.21) and actively managing my health (0.66); and the LINQ (1.85). CONLCUSIONS: Self-management, including activation, improved significantly in subjects with asthma or COPD who took part in a multidisciplinary pulmonary rehabilitation program.

"Can Do" Versus "Do Do" in Patients with Asthma at First Referral to a Pulmonologist.

BACKGROUND: Pharmacotherapy is key in asthma control, including preventing lung function decline, in primary care. However, patients' physical functioning (eg, physical capacity [PC] [=can do] and physical activity [PA] [=do do]) correlates poorly with lung function. Therefore, a better insight into the physical function of patients with asthma is needed, using the "can do, do do" concept. OBJECTIVE: To explore the "can do, do do" concept in adult patients with asthma at referral for the first time to an outpatient consultation of a pulmonologist. METHODS: PC was measured using the six-minute walk test and PA by using an accelerometer. Patients were classified into quadrants: low PC (6-minute walking distance <70% predicted), low PA (<7000 steps/d, "'can't do, don't do"); preserved PC, low PA ("can do, don't do"); low PC, preserved PA ("'can't do, do do"); or preserved PC, preserved PA ("can do, do do"). RESULTS: A total of 479 patients with asthma had a median (interquartile range) 6-minute walking distance of 74% (66%-82%) predicted, and walked 6829 (4593-9075) steps/d. Only 29% were classified as "can do, do do," whereas 30% were classified as "can't do, don't do." The Asthma Control Questionnaire and the Asthma Quality of Life Questionnaire scores were worst in the "can't do" groups. CONCLUSIONS: Low PC and/or PA was found in most patients with asthma at the index referral to a pulmonologist. An impaired PC is accompanied by a significantly reduced asthma control and disease-specific quality of life. This justifies further studies on safety and efficacy of nonpharmacological interventions, such as physiotherapy.

Efficacy and safety of a 12-week outpatient pulmonary rehabilitation program in Post-PE Syndrome.

BACKGROUND: The Post-Pulmonary Embolism Syndrome (PPES) comprises heterogeneous entities, including chronic thromboembolic disease with/without pulmonary hypertension (CTEPH/CTEPD), and deconditioning. OBJECTIVES: To assess underlying physiological determinants of PPES, and efficacy and safety of rehabilitation training in these patients. METHODS: 56 consecutive PE patients with persistent dyspnea and/or functional limitations despite ≥3 months of anticoagulation underwent standardized diagnostic work-up including exercise testing as part of routine practice. All diagnostic (imaging and cardiopulmonary function) tests were interpreted by a core group of experienced clinicians. A subgroup of patients without CTEPH or other treatable conditions was referred for a 12-week personalized rehabilitation program, studying changes in physical condition and patient-reported outcome measures. RESULTS: Persistent vascular occlusions were observed in 21/56 patients (38%) and CTEPH was confirmed in ten (18%). Regarding those without CTEPH, impaired cardiopulmonary responses were evident in 18/39 patients with available CPET data (46%), unrelated to chronic thrombi. Rehabilitation was completed by 27 patients after excluding 29 (patients with CTEPH or treatable comorbidities, refusal, ineligibility, or training elsewhere). Training intensity, PE-specific quality of life (PEmb-QoL) and fatigue (CIS) improved with a median difference of 20 W (p = 0.001), 3.9 points (p < 0.001) and 16 points (p = 0.003), respectively. Functional status (Post-VTE Functional Status Scale) improved ≥1 grade in 18 (67%) patients, and declined in one (3.7%). CONCLUSIONS: Our findings suggest that abnormal cardiopulmonary responses to exercise are common in patients with PPES and are not limited to those with chronic thrombi. Offering pulmonary rehabilitation to patients not treated otherwise seems safe and promising.

Outcomes of Pulmonary Rehabilitation After Treatment for Non-Small Cell Lung Cancer Stages I to IIIa: AN OBSERVATIONAL STUDY.

PURPOSE: Although rehabilitation after treatment for non-small cell lung cancer (NSCLC) was found to have a beneficial effect on exercise capacity in a number of studies, insight into its effect on quality of life (QoL) and fatigue is limited. The aim of this study was to examine the outcome of pulmonary rehabilitation (PR) regarding fatigue, QoL, and exercise capacity in adult patients curatively treated for NSCLC stages I to IIIa. METHODS: Study data were prospectively and routinely gathered in daily practice in patients taking part in an outpatient PR program after treatment for NSCLC stages I to IIIa. PR consisted of 12 weeks of supervised exercises 3 times a week, supplemented with scheduled visits with members of a multidisciplinary team. Data were gathered at initial assessment and discharge. Outcomes included fatigue (the Functional Assessment of Cancer Therapy-Fatigue and the fatigue domain of the Chronic Respiratory Disease Questionnaire); QoL (total CRQ score), Functional Assessment of Cancer Therapy-Lung, and the Short Form 36; and exercise capacity (cardiopulmonary exercise testing). RESULTS: Fifty patients started the program out of the 70 patients referred to PR and 43 (86%) completed the program. Significant (P ≤ .01) and clinically relevant improvements were observed for all outcome measures. CONCLUSIONS: Rehabilitation after treatment for NSCLC stages I to IIIa showed promising improvements regarding patient fatigue, QoL, and exercise capacity. PR should be considered for patients after treatment for NSCLC stages I to IIIa.

Validity and usability of low-cost accelerometers for internet-based self-monitoring of physical activity in patients with chronic obstructive pulmonary disease.

BACKGROUND: The importance of regular physical activity for patients with chronic obstructive pulmonary disease (COPD) is well-established. However, many patients do not meet the recommended daily amount. Accelerometers might provide patients with the information needed to increase physical activity in daily life. OBJECTIVE: Our objective was to assess the validity and usability of low-cost Internet-connected accelerometers. Furthermore we explored patients' preferences with regards to the presentation of and feedback on monitored physical activity. METHODS: To assess concurrent validity we conducted a field validation study with patients who wore two low-cost accelerometers, Fitbit and Physical Activity Monitor (PAM), at the same time along with a sophisticated multisensor accelerometer (SenseWear Armband) for 48 hours. Data on energy expenditure assessed from registrations from the two low-cost accelerometers were compared to the well validated SenseWear Armband which served as a reference criterion. Usability was examined in a cross-over study with patients who, in succession, wore the Fitbit and the PAM for 7 consecutive days and filled out a 16 item questionnaire with regards to the use of the corresponding device RESULTS: The agreement between energy expenditure (METs) from the SenseWear Armband with METs estimated by the Fitbit and PAM was good (r=.77) and moderate (r=.41), respectively. The regression model that was developed for the Fitbit explained 92% whereas the PAM-model could explain 89% of total variance in METs measured by the SenseWear. With regards to the usability, both the Fitbit and PAM were well rated on all items. There were no significant differences between the two devices. CONCLUSIONS: The low-cost Fitbit and PAM are valid and usable devices to measure physical activity in patients with COPD. These devices may be useful in long-term interventions aiming at increasing physical activity levels in these patients.

Drop-out and attendance in pulmonary rehabilitation: the role of clinical and psychosocial variables.

BACKGROUND: In spite of the well-demonstrated benefits for patients with COPD, pulmonary rehabilitation programmes show considerable drop-out and suboptimal attendance rates. The purpose of this prospective study is to examine causes for drop-out and non-attendance during a 12 week multidisciplinary pulmonary rehabilitation programme, and to investigate whether sociodemographic and medical factors as well as patients' perception of their illness are related to drop-out and non-attendance. METHODS: Two hundred and seventeen patients with COPD who were referred to a rehabilitation centre participated in this multicentre study. Prior to treatment, patients received a questionnaire, which included the Illness Perception Questionnaire-Revised. Clinical data were drawn from medical records. Drop-out and attendance were recorded during the programme. RESULTS: Fifty patients (23%) did not complete the rehabilitation course, of which half was due to medical reasons (e.g. exacerbations, hospitalisations). Non-completion could not be predicted by baseline sociodemographic, clinical or psychological variables. Patients who declined treatment did not differ from patients who dropped out due to medical reasons. On average, patients attended 92% of all scheduled appointments. Of all missed appointments, approximately 20% were accountable to factors beyond patients' control (e.g. absent therapists, hospitalisations). Smoking, living alone, a lower fat free mass and lower confidence in treatment increased the chance of patients not attending an appointment during rehabilitation. CONCLUSION: In general, adherence in rehabilitation is high. However, paying attention to patients' nutritional status and creating a positive expectation of treatment during referral and intake appear to be important if one aims to optimise patients' attendance during rehabilitation.
