Airway clearance techniques for patients experiencing acute exacerbations of chronic obstructive pulmonary disease in the Republic of Ireland

Background and Objectives: Airway clearance techniques (ACTs) are used by physiotherapists with the purpose of clearing sputum from bronchial airways. They are commonly prescribed for patients experiencing acute exacerbations of chronic obstructive pulmonary disease (AECOPD), however large variability in practice is commonly observed. This study aimed to explore current physiotherapy practice regarding ACTs for people with AECOPD in the Republic of Ireland. Method: An online survey was distributed to physiotherapy clinicians via direct email and the Irish Society of Chartered Physiotherapists. Main survey themes, identified from previous studies using the same survey tool, included current practice in relation to use of ACTs, perception of their effectiveness, clinical reasoning and awareness of the literature and guidelines. For the purpose of this study, ACTs were defined as techniques used by a physiotherapist for the purpose of clearing sputum from patients’ airways. Results: 202 surveys were distributed and seventy responses (35%) were received. The majority of respondents (n = 56, 80%) reported prescribing ACTs for more than 60% of patients with AECOPD, the most common techniques being physical activity (n = 65, 93%) and active cycle of breathing techniques (n = 53, 90%). Sputum management (n = 66, 94%) was the most commonly reported indicator for use of ACTs. The majority of physiotherapists (n = 42, 60%) reported being unsure of the literature regarding ACTs in AECOPD. Conclusion: The response rate to this survey was low, however results show that physiotherapists in the Republic of Ireland regularly prescribe ACTs for patients with AECOPD. Physical activity and active cycle of breathing techniques were the most commonly used ACTs and perceived to be the most effective techniques in AECOPD, with sputum management the most commonly reported indicator for use. Further research is required to explore not only physiotherapists clinical reasoning in relation to the use of ACTs for AECOPD and the perceptions of their effectiveness, but also the lack of awareness of the literature and guidelines

These may not be the courses you are seeking: a systematic review of open online courses in health professions education

Introduction: Open Online Courses (OOCs) are increasingly presented as a possible solution to the many challenges of higher education. However, there is currently little evidence available to support decisions around the use of OOCs in health professions education. The aim of this systematic review was to summarise the available evidence describing the features of OOCs in health professions education and to analyse their utility for decisionmaking using a self-developed framework consisting of point scores around effectiveness, learner experiences, feasibility, pedagogy and economics. Methods: Electronic searches of PubMed, Medline, Embase, PsychInfo and CINAHL were made up to April 2019 using keywords related to OOC variants and health professions. We accepted any type of full text English publication with no exclusions made on the basis of study quality. Data were extracted using a custom-developed, a priori critical analysis framework comprising themes relating to effectiveness, economics, pedagogy, acceptability and learner experience. Results: 54 articles were included in the review and 46 were of the lowest levels of evidence, and most were offered by institutions based in the United States (n = 11) and United Kingdom (n = 6). Most studies provided insufficient course detail to make any confident claims about participant learning, although studies published from 2016 were more likely to include information around course aims and participant evaluation. In terms of the five categories identified for analysis, few studies provided sufficiently robust evidence to be used in formal decision making in undergraduate or postgraduate curricula. Conclusion: This review highlights a poor state of evidence to support or refute claims regarding the effectiveness of OOCs in health professions education. Health professions educators interested in developing courses of this nature should adopt a critical and cautious position regarding their adoption

Validity and reliability of strain gauge measurement of volitional quadriceps force in patients with COPD

This study investigated the validity and reliability of fixed strain gauge measurements of isometric quadriceps force in patients with chronic obstructive pulmonary disease (COPD). A total cohort of 138 patients with COPD were assessed. To determine validity, maximal volitional quadriceps force was evaluated during isometric maximal voluntary contraction (MVC) manoeuvre via a fixed strain gauge dynamometer and compared to (a) potentiated non-volitional quadriceps force obtained via magnetic stimulation of the femoral nerve (twitch (Tw); n = 92) and (b) volitional computerized dynamometry (Biodex; n = 46) and analysed via correlation coefficients. Test-retest and absolute reliability were determined via calculations of intra-class correlation coefficients (ICCs), smallest real differences (SRDs) and standard errors of measurement (SEMs). For this, MVC recordings in each device were performed across two test sessions separated by a period of 7 days ( n = 46). Strain gauge measures of MVC demonstrated very large correlation with Tw and Biodex results ( r = 0.86 and 0.88, respectively, both p < 0.0001). ICC, SEM and SRD were numerically comparable between strain gauge and Biodex devices (ICC = 0.96 vs. 0.93; SEM = 8.50 vs. 10.54 N.m and SRD = 23.59 vs. 29.22 N.m, respectively). The results support that strain gauge measures of quadriceps force are valid and reliable in patients with COPD

Effects of air pollution caused by sugarcane burning in Western São Paulo on the cardiovascular system

OBJECTIVE To evaluate the effects of acute exposure to air pollutants (NO2 and PM10) on hospitalization of adults and older people with cardiovascular diseases in Western São Paulo. METHODS Daily cardiovascular-related hospitalization data (CID10 – I00 to I99) were acquired by the Department of Informatics of the Brazilian Unified Health System (DATASUS) from January 2009 to December 2012. Daily levels of NO2 and PM10 and weather data were obtained from Companhia Ambiental do Estado de São Paulo (CETESB – São Paulo State Environmental Agency). To estimate the effects of air pollutants exposure on hospital admissions, generalized linear Poisson regression models were used. RESULTS During the study period, 6,363 hospitalizations were analysed. On the day of NO2 exposure, an increase of 1.12% (95%CI 0.05–2.20) was observed in the interquartile range along with an increase in hospital admissions. For PM10, a pattern of similar effect was observed; however, results were not statistically significant. CONCLUSIONS Even though with values within established limits, NO2 is an important short-term risk factor for cardiovascular morbidity

EuReCa ONE—27 Nations, ONE Europe, ONE Registry A prospective one month analysis of out-of-hospital cardiac arrest outcomes in 27 countries in Europe

AbstractIntroductionThe aim of the EuReCa ONE study was to determine the incidence, process, and outcome for out of hospital cardiac arrest (OHCA) throughout Europe.MethodsThis was an international, prospective, multi-centre one-month study. Patients who suffered an OHCA during October 2014 who were attended and/or treated by an Emergency Medical Service (EMS) were eligible for inclusion in the study. Data were extracted from national, regional or local registries.ResultsData on 10,682 confirmed OHCAs from 248 regions in 27 countries, covering an estimated population of 174 million. In 7146 (66%) cases, CPR was started by a bystander or by the EMS. The incidence of CPR attempts ranged from 19.0 to 104.0 per 100,000 population per year. 1735 had ROSC on arrival at hospital (25.2%), Overall, 662/6414 (10.3%) in all cases with CPR attempted survived for at least 30 days or to hospital discharge.ConclusionThe results of EuReCa ONE highlight that OHCA is still a major public health problem accounting for a substantial number of deaths in Europe.EuReCa ONE very clearly demonstrates marked differences in the processes for data collection and reported outcomes following OHCA all over Europe. Using these data and analyses, different countries, regions, systems, and concepts can benchmark themselves and may learn from each other to further improve survival following one of our major health care events
