Predictors of reduced incremental shuttle walk test performance in patients with long post-COVID-19.

OBJECTIVE: One of the common limitations after COVID-19 pneumonia is the decrease in exercise capacity. The identification of the factors affecting exercise capacity and the assessment of patients at risk are important for determining treatment strategy. This study was conducted to determine the predictors of decreased exercise capacity in long post-COVID-19 patients. METHODS: We investigated the association of exercise capacity as measured by the incremental shuttle walk test (ISWT) with age, sex, spirometric variables, respiratory and peripheral muscle strength, quality of life, fatigue, hospital anxiety depression scale, chest X-ray involvement, and hospitalization. The patients were divided into three groups: outpatients, inpatients, and ICU patients. Regression analysis was used to determine which parameters were significant predictors of exercise capacity. RESULTS: Of the 181 patients included in the study, 56 (31%) were female. The mean ISWT in percentage of predicted values (ISWT%pred) was 43.20% in the whole sample, whereas that was 52.89%, 43.71%, and 32.21% in the outpatient, inpatient, and ICU patient groups, respectively. Linear regression analysis showed that predictors of decreased ISWT%pred were sex (b = 8.089; p = 0.002), mMRC scale score (b = -7.004; p ≤ 0.001), FVC%pred (b = 0.151; p = 0.003), and handgrip strength (b = 0.261; p = 0.030). CONCLUSIONS: In long post-COVID-19 patients, sex, perception of dyspnea, restrictive pattern in respiratory function, and decrease in peripheral muscle strength are predictors of reduced exercise capacity that persists three months after COVID-19. In this context, we suggest that pulmonary rehabilitation might be an important therapy for patients after COVID-19.

Health related quality of life and its determinants in COVID-19 patients.

Introduction: One of COVID-19's limitations is the reduced quality of life (QoL) caused by variety of underlying reasons. Even though multiple papers in the literature reveal a worsening of QoL after COVID-19, there is currently inadequate evidence on which patients' QoL is impacted the most. Our study's aim was to determine which patients' quality of life was most compromised so that interventions for poor QoL should not be overlooked in the post-disease assessments of those in the risk group. Materials and Methods: Patients referred to our pulmonary rehabilitation center for Long COVID symptoms had their dyspnea perception, body composition, exercise capacity, muscle strengths, and psychological state evaluated. In addition, SF-36 was used to assess their QoL. After obtaining all medical data, the patients were separated into three groups based on whether they had the disease as an outpatient, inpatient in the hospital, or in the intensive care unit. The Anova and Kruskal Wallis tests were utilized in the statistical analysis of demographic data among patient groups. Pearson's test was used for normal distributions, whereas Spearman's test was used for non-normal distribution analyses. The factors affecting QoL were investigated using multivariate linear regression analysis. Results: The majority of 173 study participants had poor QoL. Low exercise capacity (p= 0.026), impaired psychosocial status (p= 0.034 for anxiety, p= 0.022 for depression), and increased fatigue (p= 0.001) were the factors affecting SF-36's physical component summary (PCS), whereas young age (p= 0.026), male sex (p= 0.037), impaired psychosocial status (p< 0.001 for anxiety, p= 0.002 for depression), and increased fatigue (p= 0.005) were the factors affecting the SF-36's mental component summary (MCS). Conclusion: Young age, male sex, reduced exercise capacity, poor psychosocial status, and increased fatigue are predictors for impaired QoL after COVID19. Therefore, non-medical treatment options that improve QoL should be considered in the follow-up of these patients.

Long-term efficiency of pulmonary rehabilitation in patients with chronic obstructive pulmonary disease, bronchiectasis, and asthma: Does it differ?

BACKGROUND: The long-term effects of pulmonary rehabilitation (PR) and maintenance programs in obstructive pulmonary diseases have not been sufficiently investigated, particularly in diseases other than COPD. This retrospective study aimed to examine the long-term results of individualized comprehensive outpatient pulmonary rehabilitation in patients with obstructive pulmonary disease. METHODS: This study is a single-center, retrospective cohort study. Between 2010 and 2019, 269 patients with chronic airway obstruction were treated in our multidisciplinary PR center at a tertiary training and research hospital, and they were divided into three groups based on their diagnosis: COPD, bronchiectasis, and asthma. Patients' perceptions of dyspnea, exercise capacity, inspiratory and peripheral muscle strength, body composition, quality of life, and psychosocial status were compared at the beginning, end, and 12th and 24th months of PR. RESULTS: Improvements in dyspnea perception remained longer in asthmatics than in the other two groups. The increases in exercisecapacity in the bronchiectasis and asthma groups lasted two years. All groups maintained their respiratory muscle strength gains at the end of the second year. Improvements in hand grip strength in the COPD and bronchiectasis groups have been sustained for two years, but in the asthma group, enhancements were lost in the second year. Even after the second year, quality of life was still better than the baseline in all groups, despite a worsening in the first year. However, groups anxiety and depression improvements were not sustained after the first year. DISCUSSION: The long-term effectiveness of PR in patients with bronchiectasis and asthma was similar to that of COPD patients. Therefore,multidisciplinary, comprehensive PR programs should be integrated into the management of patients with bronchiectasis and asthma. We also recommend structured follow-up programs to maintain gains and to detect the need for rerehabilitation.

The relation between inspiratory muscle strength and bacterial colonization and other clinical factors in patients with non-cystic fibrosis bronchiectasis.

Introduction: This study aimed to investigate whether inspiratory muscle strength was associated with bacterial colonization and other clinical outcomes and whether bacterial colonization was associated with clinical outcomes in patients with non-cystic fibrosis bronchiectasis (NCFB). Materials and Methods: Eighty-six patients were enrolled in a cross-sectional study. Patients were divided into two groups according to the presence of inspiratory muscle weakness and bacterial colonization. Parameters were compared between groups. Result: Bronchiectasis etiologies were post-infectious, Kartagener's syndrome, and primary ciliary dyskinesia. The median value of MIP was -68, and MEP was 89 cm H2O in all patients. Although the ratio of bacterial colonization was similar to patients without inspiratory muscle weakness, the inspiratory muscle weakness group had a higher number of females, lower FEV1, FVC, ISWT, CRQ, higher MRC, E-FACED, SGRQ, number of hospitalization (p<0.05). When colonized and non-colonized patients were compared, MIP, and MEP were similar in spite of adjusted BMI, age, and sex. FEV1, FVC, ISWT, and ESWT were lower, and E-FACED scores (p<0.05) were higher in colonized patients. Conclusions: Although inspiratory muscle strength was not associated with bacterial colonization in NCFB patients, it is an important factor that could be linked to disease severity, pulmonary functions, quality of life, and exercise capacity. Bacterial colonization was also associated with severe disease, deteriorated pulmonary functions, and exercise capacity.

Relation of impulse oscillometry and spirometry with quantitative thorax computed tomography after COVID-19 pneumonia.

OBJECTIVE: This study aimed to investigate if there is any correlation between the quantitative computed tomography and the impulse oscillometry or spirometry results of post-COVID-19 patients. METHODS: The study comprised 47 post-COVID-19 patients who had spirometry, impulse oscillometry, and high-resolution computed tomography examinations at the same time. The study group consisted of 33 patients with quantitative computed tomography involvement, while the control group included 14 patients who did not have CT findings. The quantitative computed tomography technology was used to calculate percentages of density range volumes. The relationship between percentages of density range volumes for different quantitative computed tomography density ranges and impulse oscillometry-spirometry findings was statistically analyzed. RESULTS: In quantitative computed tomography, the percentage of relatively high-density lung parenchyma, including fibrotic areas, was 1.76±0.43 and 5.65±3.73 in the control and study groups, respectively. The percentages of primarily ground-glass parenchyma areas were found to be 7.60±2.86 and 29.25±16.50 in the control and study groups, respectively. In the correlation analysis, the forced vital capacity% predicted in the study group was correlated with DRV%[(-750)-(-500)] (volume of the lung parenchyma that has density between (-750)-(-500) Hounsfield units), but no correlation with DRV%[(-500)-0] was detected. Also, reactance area and resonant frequency were correlated with DRV%[(-750)-(-500)], while X5 was correlated with both DRV%[(-500)-0] and DRV%[(-750)-(-500)] density. Modified Medical Research Council score was correlated with predicted percentages of forced vital capacity and X5. CONCLUSION: After COVID-19, forced vital capacity, reactance area, resonant frequency, and X5 correlated with the percentages of density range volumes of ground-glass opacity areas in the quantitative computed tomography. X5 was the only parameter correlated with density ranges consistent with both ground-glass opacity and fibrosis. Furthermore, the percentages of forced vital capacity and X5 were shown to be associated with the perception of dyspnea.

Tele-pulmonary rehabilitation with face to face in COVID-19 pandemic: A hybrid modeling.

Introduction: Post-illness pulmonary rehabilitation indications of Coronavirus disease-2019 (COVID-19) may include fatigue, respiratory restriction, exercise limitation, muscle weakness, deterioration in body composition, quality of life, and psychological status. Since tele-pulmonary rehabilitation (tele-PR) is the prominent approach in the current situation and questions such as who, how, and when are still unclear, in this study we aimed to investigate the efficacy of tele-PR as a hybrid model with face-to-face in post-COVID-19 patients. Materials and Methods: Thirty one patients who had completed viral infection treatment with the diagnosis of COVID-19 but still had persistent symptoms were enrolled in an eight-week synchronized video-conference mediated telePR program in a hybrid format, with the initial and final assessments and the first two sessions conducted in person. Before and after the tele-PR, pulmonary functions, exercise capacity, respiratory and peripheral muscle strength, body composition, quality of life, and psychological states were evaluated. Result: After the tele-PR program; a statistically significant improvement was observed in dyspnea sensation evaluated with modified Medical Research Council (mMRC) and BORG levels, body mass index (BMI), incremental shuttle walk test (ISWT), endurance shuttle walk test (ESWT), handgrip test, deltoid, and quadriceps 1-repetition maximum (1RM) results, maximal inspiratory and expiratory pressure (MIP, MEP), peripheral muscle strengths, fatigue severity scale and Nottingham extended activities of daily living scale (NEADLS). Conclusions: In this study, it has been shown that the hybrid model of tele-PR enables a comprehensive evaluation as well as the effective and safe applicability of a multidisciplinary and remotely directed program even in high workloads for post-COVID-19 patients.

Relationship between exercise capacity and impulse oscillometry parameters after COVID-19 infections.

BACKGROUND: After COVID-19 infection, persistent exercise intolerance, changes in lung function have been shown. Our aim is to investigate the correlation between impulse oscillometry (IOS) parameters and exercise capacity by using incremental and endurance shuttle walk tests (ISWT, ESWT) and investigate the factors and parameters which might have an effect on both IOS parameters and exercise capacity tests. METHOD: The patients who had a history of COVID-19 were enrolled into cross-sectional study according to inclusion criteria. The IOS parameters, ISWT, ESWT, smoking status, time since COVID-19 diagnosis, length of hospital stay, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), body mass index (BMI), fat-free mass index (FFMI), dyspnea, hospital anxiety-depression and fatigue severity scores were recorded. RESULTS: The study comprised 72 patients, 71% of whom were male, with a mean age of 54 ± 10 years. After COVID-19 diagnosis, the median duration was 3 (min: 1, max: 5) months and 51 (71%) of the patients were hospitalized. The FEV1 and FVC values were in normal range. The area of reactance (AX), resonance frequency (Fres), reactance at 20 Hz (X20) and the difference between resonance at 20 and 5 Hz (R5-20) correlated with both ISWT and ESWT. The FEV1 correlated with all IOS parameters (p < 0.05). Reactance correlated with FFMI (p = 024, r = 0.267), different according to hospitalization (p = 0.02). CONCLUSION: In COVID-19 survivors, there could be correlations between IOS parameters and exercise capacity; and between these parameters and FEV and FVC. Furthermore, small airway disease with normal spirometric functions could be related to decreased exercise capacity in COVID-19 survivors regardless of concomitant diseases, BMI, smoking status and time since COVID-19 diagnosis.

Factors affecting the success of pulmonary rehabilitation in asthma.

OBJECTIVE: The majority of patients with asthma limit their physical activity due to the fear of exercise dyspnea. Regular exercise, on the other hand, is currently suggested as one of the non-pharmaceutical treatment alternatives for patients with asthma since it improves their quality of life and symptom control. This study aimed to investigate the indicators of success in patients with asthma receiving pulmonary rehabilitation (PR). METHODS: A total of 131 patients with the diagnosis of asthma were included in the study. All patients attended an 8-week comprehensive, multidisciplinary, outpatient and individualized PR program. RESULTS: The factors related to the gains in dyspnea perception, exercise capacity, peripheral muscle strength, respiratory muscle strength and quality of life were evaluated. In the multivariate linear regression analysis, the gain in dyspnea perception is related to baseline dyspnea. The gain in exercise capacity is related to baseline exercise capacity and the amount of smoking. The gain in peripheral muscle strength is related to gender. The gain in respiratory muscle strength is related to age, and finally the gain in quality of life is related to baseline dyspnea and anxiety levels. CONCLUSIONS: Especially men, young people, heavy smokers, and those with low initial exercise capacity, high perception of dyspnea, and high anxiety are more likely to benefit from PR.

Multidimensional factors affecting medication adherence among patients with chronic obstructive pulmonary disease.

AIMS AND OBJECTIVES: This study aimed to investigate the effects of socioeconomic-, patient-, treatment-, condition- and health system-related factors on medication adherence in patients with chronic obstructive pulmonary disease (COPD). BACKGROUND: Medication adherence is essential for the management of chronic diseases. The World Health Organization created a Multidimensional Adherence Model (MAM) and showed that medication adherence is affected by a combination of numerous factors. DESIGN: A descriptive correlational study was conducted. METHODS: A total of 114 patients with COPD were included. Data were collected on five dimensions based on the MAM framework. Medication adherence, self-efficacy and symptoms were evaluated using the Adherence to Refills and Medications Scale-7 (ARMS-7), COPD Self-Efficacy Scale (CSES) and COPD Assessment Test (CAT), respectively. The data were analysed using descriptive statistics, correlational statistics and structural equation modelling. The STROBE checklist was used. RESULTS: The ARMS-7 scores were associated with the body mass index of patients (F = 4.245, p = .017), smoke pack-years (r = .277, p = .004) and the CSES total score (ß = -0.249, p = .002) in patient-related factors. The ARMS-7 score was not associated with socio-economic and health system-related factors. The ARMS-7 score showed a significant correlation between COPD diagnosis duration (r = -.276, p = .003) and the total number of drugs (r = -.215, p = .022) in treatment-related factors. The ARMS-7 scores were associated with the number of comorbid illnesses of patients with COPD in condition-related factors (F = 3.533, p = .033). CONCLUSION: This study showed that medication adherence in COPD was mostly affected by patient-, treatment- and condition-related factors. RELEVANCE TO CLINICAL PRACTICE: Healthcare professionals should establish training and counselling programs to increase the medication adherence level of patients, particularly for patients who are newly diagnosed, require multiple drugs and have comorbid diseases or low self-efficacy.

The effect of comprehensive multidisciplinary pulmonary rehabilitation on 5-year survival in COPD: does maintaining a home exercise program improve survival?

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) is one of the most common causes of death worldwide. Therefore, optimizing medical therapy in the comprehensive management of the disease, as well as including pulmonary rehabilitation (PR) in the treatment, is essential. The goal of our study was to determine the impact of PR on the survival of COPD patients. METHODS: Between 2007-2015, 509 COPD patients who completed the PR constituted the PR group, while 167 patients who applied but could not complete it after the initial evaluations formed the control group. In the PR group, dyspnea perception, exercise capacity, muscle strength, body composition, quality of life, psychosocial status, and i-BODE scores were assessed at the beginning and end of the program, whereas in the control group, these assessments could only be conducted at the beginning. Also, after PR, our PR participants have prescribed a home exercise program, and they were recalled to the hospital at the 3rd, 6th, 12th, 18th, and 24th months for follow-up visits. RESULTS: A statistically significant improvement was found in almost all the data (except FEV1/FVC, BORG after exercise, and FFMI) after PR. There was a statistically significant difference in 5-year survival in favor of the PR group (p = 0.006), and in PR patients who accompanied the home exercise program vs. those who did not (p = 0.000). Also the gains in MRC (p = 0.003; OR: 2.20; CI: 1.319- 3.682), MEP (p = 0.041; OR: 1.02; CI: 1.001-1.035), and i-BODE (p = 0.006; OR: 0.914; CI: 0.857-0.974) increased the survival. DISCUSSION: Apart from incorporating PR into treatment in the comprehensive management of COPD, we demonstrated that maintaining a home exercise program for at least two years following PR increased 5-year survival significantly.

Maintenance of pulmonary rehabilitation benefits in patients with COPD: is a structured 5-year follow-up program helpful?

Background/aim: Pulmonary rehabilitation (PR) has proven useful in patients with chronic obstructive pulmonary disease (COPD), but the benefits decrease over time. We evaluated the effects of a structured follow-up program after PR on patient pulmonary function, dyspnea, body composition, exercise capacity, quality of life, psychological status, i-BODE index, hospitalization status, 5-year survival rate. We explored whether this follow-up program could serve as a maintenance program. Materials and methods: COPD patients who completed PR attended follow-up visits over 5 years. We administered incremental (ISWT), endurance shuttle walk tests (ESWT), measured body (BMI), fat-free mass indices (FFMI), recorded modified Medical Research Council (mMRC), St. George's respiratory questionnaire (SGRQ), anxiety-depression scores. We also noted the forced expiratory volume in 1 s (FEV1), the forced vital capacity (FVC), the forced midexpiratory flow (FEF25-75), hospitalization, survival rates before, after PR, and in years 1, 2, 3, 5. This was a retrospective observational study. Results: Thirty-three COPD patients with a mean age of 58 ± 8 years were enrolled. Twenty-seven (82%) were male. The mean FEV1 was 47 ± 16% of the predicted. After PR, the mMRC scale, SGRQ, anxiety, depression scores; i-BODE index; ISWT, ESWT results improved (all p < 0.001), with the improvements persisting through the first year. Patient body composition, pulmonary function did not differ from the baseline over the 5 years (except for a decrease in the FEF25-75 value in year 5; p = 0.003). The hospitalization rate, i-BODE index did not change significantly over the 5 years, the improvements in the ISWT, ESWT outcomes were preserved for 3 years (p = 0.013/0.005, respectively). The quality-of-life, anxiety scores deteriorated in year 1 (both p < 0.001) and year 3 (p = 0.005/0.010, respectively). The dyspnea, depression scores increased progressively over the 5 years. Conclusion: Structured follow-up programs with visits at 6-month intervals may effectively maintain improvements in COPD. Long-term randomized controlled studies are needed to verify these results.

Pleuroparenchymal fibroelastosis: from diagnosis to pulmonary rehabilitation.

Pleuroparenchymal fibroelastosis (PPFE) is an uncommon disease of which diagnosis should be established multidisciplinary fashion and has no effective medical therapy. Pulmonary rehabilitation (PR) can be applied, but lung transplantation is the only therapeutic option. There have been few reported cases or studies showing the efficacy of PR in patients with PPFE in the literature. We present our multidisciplinary PR programme including confirmation of the diagnosis and a structured follow-up programme in two PPFE patients. In both cases, after multidisciplinary PR the diagnoses were confirmed and body composition, quality of life, exercise capacity and psychological status improved and some improvements preserved for 6-12 months. They underwent lung transplantation about 2 years after PR. Patients with PPFE should be directed and encouraged to participate in comprehensive multidisciplinary PR programmes. Long-term structured follow-up programmes could preserve the improvements, increase adherence and save time while waiting on the transplant list.

Hospital-at-home for chronic obstructive pulmonary disease exacerbation: Will it be an effective readmission avoidance model?

OBJECTIVES: Hospital-at-home (HAH), a pioneering health care model, is an accepted alternative to hospital treatment for patients with a chronic obstructive pulmonary disease (COPD) exacerbations. The aim of the present study was to analyze the effectiveness of HAH for patients with COPD exacerbations. METHODS: Two hundred six patients with COPD exacerbations who were admitted to our emergency room (ER) received the HAH model between January 2008 and March 2010. The number of patient's hospitalization, admission to emergency room, unscheduled outpatient attendance, and the length of stay in hospital (day) were recorded before and after a one-year period of HAH. RESULTS: After a one-year follow-up period of the HAH program, the number of patient who had hospitalization, admission to ER, unscheduled outpatient attendance rates was decreased 41.3%, 54.4%, 49.5% respectively. The decreases for all parameters were found to be statistically significant (P < 0.001). Additionally the total number of length of stay in hospital (day) after a one-year period after HAH was decreased (46.5%). CONCLUSION: Integrated care services, including home care units where HAH models are performed, are necessary to improve the health of patients with COPD, as well as to better manage their condition in terms of disease burden. Physicians should consider this form of management, especially because there is increasing pressure on inpatient bed requirement in Turkey.

Efficacy of pulmonary rehabilitation for bronchiectasis and related factors: which patients should receive the most treatment?

INTRODUCTION: Pulmonary rehabilitation (PR) is an effective approach for patients with chronic pulmonary disease, and it is also recommended for patients with bronchiectasis. The aims of the current study were to evaluate the efficacy of a multidisciplinary PR program and identify factors associated with improvement in patients with bronchiectasis. Material and ethods: We obtained data from patients with bronchiectasis who completed our PR program which consisted of education and training regarding bronchial hygiene. Pulmonary function test results, body composition, exercise capacity, quality of life, and psychological status were assessed before and after the PR program. RESULTS: We enrolled 130 patients in this retrospective study. Most patients had a history of pneumonia. The Medical Research Council (MRC) dyspnea scale, incremental shuttle walking test (ISWT), endurance shuttle walking test (ESWT), St. George's Respiratory Questionnaire (SGRQ), Chronic Respiratory Questionnaire (CRQ), and Hospital Anxiety and Depression (HAD) scores statistically improved after the PR program (all p < 0.001). Improvements were similar regardless of sex, etiology, smoking sta-tus, or number of hospitalizations. Age was negatively correlated with ΔSGRQ (p = 0.024, r = -0.203). Baseline forced expiratory volume in 1s (FEV1) was positively correlated with ΔCRQ (p = 0.015, r = 0.213) and negatively correlated with Δanxiety (p = 0.014, r = -0.215). Baseline MRC was negatively correlated with ΔMRC (p < 0.001, r = -0.563) and ΔSGRQ (p < 0.001, r = -0.308). Baseline ISWT was negatively correlated with ΔISWT (p = 0.043, r = -0.176) and Δanxiety (p = 0.007, r = -0.237). Baseline SGRQ was negatively correlated with ΔMRC (p = 0.003, r = -0.267) and ΔSGRQ (p < 0.001, r = -0.648). CONCLUSIONS: Our PR program is efficacious for patients with bronchiectasis regardless of sex, etiologic cause of bronchiectasis, concomitant chronic obstructive pulmonary disease, smoking status, and/or number of hospitalizations. Improvement varied among patients which highlights the need for more studies to determine which patients will benefit most from the program.

Patients with COPD who underwent pulmonary rehabilitation in Turkey: prevalence, distribution, and mortality

Background: Pulmonary rehabilitation (PR) is an effective, evidenced-based treatment. Despite its proven effect, it is still underused. The aim of this study was to present the number of patients with chronic obstructive pulmonary disease (COPD) who underwent PR, general mortality percentages, the rate of patients prescribed PR by pulmonologists, and the distribution of institutions where PR was performed between 2008 and 2016 in Turkey. Materials and methods: The documents were obtained from Turkish Institution of Social Insurance. Ages, sexes, and numbers of patients with COPD who underwent PR between 2008 and 2016 were recorded. The number of patients with COPD who had been prescribed PR by physicians and the type of hospitals in which these patients underwent PR were identified. The general annual and the general total mortality rates between 2008 and 2016 among patients with COPD who underwent PR in 2008 were also determined. Results: The mean age ranges of patients with COPD who underwent PR were 67.4 ± 12.3 to 72.0 ± 13.2 years, and 62.2% (n = 60,852) of patients were male. The number of patients increased progressively from 3,214 to 18,664. The rate of patients prescribed PR programs between 2008 and 2016 was between 0.32% and 0.59% among all registered patients with COPD. Between 52.0% and 94.8% (5,488/10,549 and 16,792/17,707 patients, respectively) of the programs were prescribed by a pulmonologist, and 62.9% (n = 62,613) of patients received PR in secondary public hospitals. The general annual mortality rates were between 6.2% and 11.1% (115/1,855 and 358/3,214 patients) in patients who underwent PR in 2008, and the general total mortality rate was 52.8% (1,696/3,214 patients) over the 9-year period in the same patient group. Conclusion: PR was still an underutilized approach in Turkey between 2008 and 2016. The awareness of PR should be increased in our country. In order to achieve this, we think that PR should be within the scope of health policies.

Comparison of unsupervised home-based pulmonary rehabilitation versus supervised hospital outpatient pulmonary rehabilitation in patients with chronic obstructive pulmonary disease.

Background: Pulmonary rehabilitation (PR) is an effective treatment in patients with chronic obstructive pulmonary disease (COPD) but still underutilized. The aim of this study was to compare unsupervised home PR with supervised outpatient PR in terms of various clinical variables in COPD patients.Methods: We conducted retrospective study consisting of 247 patients with COPD who were categorized into three group. 127 patients underwent unsupervised home PR, of whom 60 (47%) completed program (finishers), 67(53%) were lost to follow-up (non-finishers), 120 completed supervised outpatient PR. We compared baseline, post-treatment changes in demographic, clinical variables.Results: Sex, age were statistically similar between groups. Finishers of home PR had higher exercise capacity (p = 0.003), quality of life (p = 0.045), FEV1 (p = 0.001), lower pack-year smoking (p < 0.001) than outpatient PR.After home PR, exercise capacity (p < 0.05), quality of life (p < 0.001), dyspnea(p < 0.05), anxiety (p < 0.001), depression (p < 0.001) were improved except endurance shutte test. Improvements in exercise capacity (p < 0.05), quality of life (p < 0.001), dyspnea (p = 0.023), anxiety (p < 0.001), depression (p = 0.001) scores were different between completed PR programs, in favor of supervised outpatient PR. Non-finishers of home PR had more pack-year smoking than finishers of home PR (p = 0.039); other baseline parameters were similar.Conclusion: Unsupervised home PR was effective in terms of improving exercise capacity, quality of life, dyspnea, psychological status, but less than supervised outpatient programs.

Use of i-BODE index to determine efficacy of pulmonary rehabilitation in COPD patients.

INTRODUCTION: Pulmonary rehabilitation (PR) is well-proven approach on improving dyspnea, exercise intolerance which are two components of BODE index. But, PR is known to have minimal effect on pulmonary function which is another component of BODE index. There are few studies evaluating PR efficacy by using i-BODE index. Our aim was to evaluate efficacy of PR in patients with chronic obstructive pulmonary disease (COPD) with i-BODE index and to investigate changes in i-BODE index according to GOLD 2011 combined assessment. MATERIALS AND METHODS: A total of 228 stable COPD patients who completed a comprehensive 8 week duration PR program were enrolled into this retrospective study. RESULT: The patients were with mean age of 63.3 ± 8.6 years and mean FEV1% was 38.6 ± 16.2%. According to combined assessment of COPD, 23 patients were group A, 30 patients were B, 31 patients were C and 144 patients were D. Baseline i-BODE scores correlated with body compositions, pulmonary function, dyspnea, exercise capacity, psychological status, quality of life, and age. i-BODE index score decreased from 4.7 ± 2.2 to 3.5 ± 1.8 after PR (p<0.001), improved by 26%. Significant improvements were found in dyspnea, quality of life and i-BODE index in more symptomatic patients (group B and D). CONCLUSIONS: This study highlights that changes in i-BODE scores after PR significantly correlated with improvements in dyspnea, exercise capacity and quality of life. i-BODE score could be a better predictor of efficacy of PR than some individual variables such as BMI or FEV1. Significant improvements in dyspnea sensation, quality of life and i-BODE index could be seen symptomatic patients in after PR.
