Filter by:Chronic obstructive pulmonary disease (COPD) is the leading cause of morbidity and mortality worldwide, a respiratory disease characterized by chronic airflow limitation that is not completely reversible. Impaired pulmonary functions, decreased exercise capacity and quality of life and increased dyspnea perception is prevalent in patients with acute exacerbations of COPD.It was demonstrated exercise training has beneficial effects in patients with acute exacerbations of COPD. The purpose of this study to evaluate the effects of chair-based exercise training on exercise capacity, respiratory functions, dyspnea, balance, depression anxiety and quality of life in COPD patients in acute exacerbation.
INTRODUCTION: Relationship between comorbidities and COPD is two-sided. While the number of comorbidities increasing, the frequency of acute exacerbations of COPD (AECOPD) is increasing, too. Comorbidity indexes can be used for recognition of comorbidities while managing COPD patients. In the present study, it is aimed to compare comorbidity indexes such as Charlson Comorbidity Index, COMCOLD and COTE in the matter of exacerbation frequency. METHOD: Subjects hospitalized for AECOPD, admitted to the study. Exacerbation severity, frequency, further exacerbations for a 1-year period in the follow-up period and CCI, COMCOLD and COTE scores were recorded. High and low comorbidity groups were compared for AECOPD frequency, severity, and further exacerbations.
This is a randomised controlled trial of the blood flow restriction resistance exercise (BFR-RE) for early rehabilitation of chronic obstructive pulmonary disease acute exacerbation (COPDAE) in the Haven of Hope Hospital. BFR-RE was invented by Dr. Yoshiaki Sato in Japan 40 years ago. This exercise was newly introduced to the Physiotherapy Department of Haven of Hope Hospital in March, 2020 and not a routine common training in Hospital Authority. However, currently the "BFR-device" is in its 3rd generation. Under the guidance of a certified physiotherapist, a "low load intensity" can be used for resistance training to build up muscle mass and strength by applying the device over the thigh to partially limit the blood flow to the distal limb. BFR-RE is well studied in athletes, elderlies and patients for rehabilitation after orthopaedics surgeries. A large amount of literature reveals BFR-RE with "low load intensity" shows comparable increase of muscle mass as "high load intensity" resistance training and more increase of muscle strength than those only undergoing "low load intensity" resistance training. The objective of this study is to investigate the additional effects of 2-week BFR-RE in patients with COPDAE on top of the conventional in-patient rehabilitation training. The primary outcome is effect on localized muscle strength. The secondary outcomes include mobility function, systemic muscle strength as reflected by handgrip strength(HGS), health related quality of life, unplanned readmission to acute hospital rate within 1 month for COPDAE.
Non invasive ventilation is the standard of care in managing patients with exacerbation of chronic obstructive pulmonary disease. However no optimal mode of NIV delivery is established; failure rates remain high, attributed to asynchrony and leak associated with NIV. Neurally adjust ventilator assist is a new mode that may improve patient ventilator interactions, improve synchrony and contribute to improved outcomes. Likewise ASV is a mode principled on the closed loop system and is associated with reduction of work associated with breathing and improved outcomes. In this randomised, non-blinded trial, we study these two modes of NIV delivery in patients of AECOPD with hypothesis being that better synchrony with NAVA may translate to better clinical outcomes.
Up to 90% of consulting Acute Exacerbation (AE) of COPD patients are prescribed an antibiotic(1). Rates of inappropriate antibiotic prescription percentage can be as high as 65%(2). Excessive use of antibiotics is correlated with higher prevalence of antimicrobial resistance(3). There are insufficient data regarding the overprescribing antibiotics in AECOPD in our country.Therefore the investigators aimed to investigate the patients factors that are associated with the prescription of antibiotic for inappropriate indication in AECOPD.This is an observational cross sectional study.Population: AECOPD patients with AB(antibiotic) prescription Exposure: Presence of patient factors, Comparison: Absence of Patient factors, Outcome: Prescription of antibiotic for inappropriate indication. Sampling: Consecutive patients presenting to pharmacy between Monday and Friday. Date between January 1 2017 to January 1 30 2019. Primary Outcome:Prescription of antibiotic for inappropriate indication according to Anthonisen criteria for AECOPD Anthonisen criteria:-Worsening of dyspnea - Increased sputum volume - Increased sputum purulent 3/3 →Type 1 or severe AE 2/3 →Type 2 or moderate AE 1/3 →Type 3 or mild AE AB indicated/useful in Type 1 or severe AE, and Type 2 or moderate AE if sputum is purulent The data will be obtained from the database. Exposure: Patient factors that lead to inappropriate antibiotic prescription (will be considered together in analysis due to confounding) FEV1% Age Current smoker Comorbidities (Charlson comorbidity index) having Frequent exacerbations (≥2 past year) Use of oral steroids Polypharmacy Quality control:Detailed MOP will be developed, A manual for protocol will be written and used to inform the pharmacist,Pharmacist will be trained; to speak to participants in a neutral manner for written informed consent for the security ID(identity) data of the patients,This study will not affect the time period of the participants to access his/her drug. The pharmacy will use the questionnaire within the time period planned. A checklist for exclusion criteria will be developed. A plan for missing data will be developed. Null hypothesis: Patient factors are not associated with the prescription of antibiotics for inappropriate indications in patients with AECOPD Alternative hypothesis: Patient factors are associated with the prescription of antibiotics for inappropriate indications in patients with AECOPD Analysis The data will be analysed using SPSS version 22.0 The investigators will compare exposure variables between inappropriate and appropriate prescription groups Continuous variables - t test or Mann Whitney Binary- chi square test The investigators will use logistic regression to measure the associations between patient factors and the outcome of prescription of antibiotics for inappropriate indication Sample size and power Sample size to estimate CI of 15% around 25 to 50% prevalence of inappropriate prescription with p=0.05 and Power 80% Expected proportion0,25 128 0,50 171 Sample size and power For logistic regression - estimate 30% prevalence (n=143), or about 42 events . The investigators also need 5-10 events for each variable in the model, so this provides sufficient power for 4 to 8 factors. Limitations This study will just determine an association not causality The investigators won't be able to determine if the participant is truthful to the pharmacist The history of participants will be assessed from hospitals e-database - potential for missing data. The Anthonisen criteria for identifying inappropriate AB for AECOPD are still debatable The investigators can not modify many of the patient factors, but may be able to identify patients at higher risk of inappropriate antibiotics Ethics The project will be submitted to the ethical committee of Dr. Suat Seren Chest Disease Hospital Oral and written informed consent will be obtained from all subjects The study will be conducted in accordance with "Good Clinical Practice Guideline" Relevance This study will be the first one to evaluate an association between patient factors and prescription of antibiotic for inappropriate indication in an outpatient clinic of patients with AECOPD in Turkey. Subsequent studies should evaluate physician factors prescription of antibiotic for inappropriate indication.
