Can an educational intervention in the context of inpatient pulmonary rehabilitation improve asthma self-management at work? A study protocol of a randomized controlled trial.

BACKGROUND: Asthma self-management (e.g., trigger avoidance or correct medication use) is a cornerstone of therapy. Its successful implementation in everyday working life is determined by psychosocial working conditions, in particular by support from superiors and colleagues and the job decision latitude (i.e., when and how to carry out which tasks). To empower individuals with asthma to modify their working conditions, employees need to use certain communication skills and acquire specific knowledge. Both could be taught as part of patient education during pulmonary rehabilitation. Therefore, the aim of the planned study is the development and multicentre implementation of an education module for individuals with asthma during their rehabilitation and to generate evidence on its effectiveness. METHODS: Participants (n ≥ 180) will be recruited, randomized into an intervention and a control group, trained and surveyed in two rehabilitation clinics. The intervention group will receive the supplementary patient education module "Asthma and Work" while the control group will participate in a program on " Eating behaviour" (both 2 × 50 min). The effectiveness of the intervention will be examined based on pre-post measurements (T1 and T2) and a 3-month follow-up (T3). We will consider behavioural intention (T2) and asthma self-management at work (T3) as primary outcomes. Secondary outcomes will include self-management-related knowledge, self-efficacy, number of sick days, number of exacerbations, asthma control (Asthma Control Test), asthma-related quality of life (Marks Asthma Quality of Life Questionnaire), and subjective employment prognosis (Brief Scale Measuring the Subjective Prognosis of Gainful Employment). The pre-post comparisons are to be evaluated using univariate analyses of covariance. DISCUSSION: Improving asthma self-management at work could increase the work ability and social participation of employees with asthma. This could reduce costs, e.g. in terms of asthma-related sick leave. TRIAL REGISTRATION: German Clinical Trials Register (ID: DRKS00031843).

Prehabilitative high-intensity interval training and resistance exercise in patients prior allogeneic stem cell transplantation.

Physical capacity prior allogeneic stem cell transplantation (allo-HCT) has been shown as a relevant prognostic factor for survival after transplant. Therefore, we evaluated feasibility and preliminary efficacy of a high-intensity interval training (HIIT) and moderate to high-intensity resistance exercise (RE) to increase physical capacity in patient's prior allo-HCT. In this multicentre single arm pilot study, a supervised exercise program was performed twice weekly for 4-12 weeks prior allo-HCT, depending on the individual time remaining. Outcomes were feasibility (recruitment, adherence, safety), physical capacity (cardiorespiratory fitness [VO2peak], muscle strength) and patient reported outcomes (physical functioning, fatigue). Thirty patients were intended, 16 could be included, and 14 completed post intervention assessment (75% male, 55 ± 11 years). The study was stopped early due to a low recruitment rate. Nine patients (64%) reached the initial minimum planned number of eight exercise sessions. Individual adherence was high with 92% for HIIT and 85% for RE. 87% of all performed exercise sessions were completed without complaints and VO2peak increased significantly from 20.4 to 23.4 ml/kg/min. The low recruitment rate suggests that initiation of the intervention concept immediately before allo-HCT is feasible only in a small number of patients. In particular, the timeframe directly prior allo-HCT seems too short for exercise interventions, although the exercise program was designed to improve outcomes in a very short time frame. HIIT and RE were feasible, effective and well accepted by the included patients.

[Smoking Cessation and Prescription of Ambulatory Exercise Training as Part of Pulmonary Rehabilitation in Germany]. / Tabakentwöhnung und Verordnung von ambulantem Lungensport im Rahmen der pneumologischen Rehabilitation in Deutschland.

PURPOSE: This survey was conducted on behalf of the German Respiratory Society (DGP) section 12. The aim was to assess the means of achieving tobacco cessation and prescription of exercise training on an outpatient basis after discharge from pulmonary rehabilitation clinic as part of aftercare of pulmonary rehabilitation programs in Germany. METHODS: We contacted all pulmonary rehabilitation clinics in Germany. Of the 67 clinics we identified, 62 fulfilled the inclusion criteria; 39 clinics (62.9 %) agreed to participate and returned the completed questionnaires. RESULTS: Each clinic rated ambulatory exercise training sessions as effective aftercare. In each case, slightly above 50 % of the sample informed their patients via standardized talks or information brochures. In 38.5 % of the clinics, ambulatory exercise in groups was provided as aftercare. The number of patients who received prescription for aftercare at the end of the rehabilitation program ranged between 0 % and 100 %. Only a quarter of the clinics had ever been asked by the funding organizations regarding the success rate of the exercise program. All clinics assessed the smoking status of their patients and explained the importance of tobacco abstinence to them. The percentage of smokers was estimated to be 33 %; 69.7 % of the clinics stated that the rehabilitation program included standardized talks regarding tobacco cessation and 61.5 % reported having therapeutic group meetings on a regular basis. Further treatment options included psychological counselling (89.7 %), nicotine replacement therapy (61.5 %), or varenicline (15.4 %). Aftercare was offered only in 10.3 % of the clinics. On average, the percentage of smokers who achieved tobacco abstinence during the rehabilitation program was 32 %. Only one clinic (2.6 %) had ever been asked by the funding organization regarding the success rate of the tobacco cessation program. CONCLUSION: This survey emphasizes that most of the pulmonary rehabilitation clinics in Germany have already achieved a good standard regarding tobacco cessation and exercise training programs for their inpatients; however, there are still areas of improvement as far as providing care after discharge from a rehabilitation clinic is concerned with regard to smoking cessation and prescription of ambulatory exercise training.

Influencing factors of cardiorespiratory fitness in allogeneic stem cell transplant candidates prior to transplantation.

PURPOSE: Cardiorespiratory fitness (CRF) seems to be prognostic prior to allogeneic stem cell transplantation (allo-HSCT). Influencing factors of CRF in allo-HSCT candidates have not been studied so far. Aim was to identify potentially influencing factors on CRF. METHODS: To assess CRF, a maximal cardiopulmonary exercise test (CPET) was performed on average 2.6 ± 7.2 days prior to admission. A regression analysis was conducted, with the following predictors: gender, age, body mass index (BMI), time between last therapy and allo-HSCT (t_Therapies), number of cardiotoxic therapies (n_Cardiotox), number of transplantations (n_Transplantations), comorbidity index (HCT-CI), hemoglobin level of the last 3 months (area under the curve), and physical activity. RESULTS: A total of 194 patients performed a CPET. VO2peak was significantly reduced compared with reference data. In total, VO2peak was 21.4 ml/min/kg (- 27.5%, p < 0.05). Men showed a significant larger percentage difference from reference value (- 29.1%, p < 0.05) than women (- 24.4%). VO2peak was significantly (p < 0.05) influenced by age (ß = - 0.11), female gender (ß = - 3.01), BMI (ß = - 0.44), n_Cardiotox (ß = - 0.73), hemoglobin level (ß = 0.56), and physical activity prior to diagnosis (ß = 0.10). CONCLUSIONS: Our study demonstrates a decreased CRF indicating the potential need of prehabilitative exercise. We revealed some influencing factors on CRF. Those patients could benefit the most from exercise.
