Exploring human error through the safety talk of utilities distribution operatives

Cable strikes form a significant safety challenge for the construction industry’s utilities sector. Such incidents can and do result in both death and injury for the workforce, as well as costing companies millions of pounds in associated damages and compensation costs. Despite specialized tools, processes and training programmes, cable strikes still occur on a regular basis. The majority of cable strikes are, like many incidents within the construction industry as a whole, attributed to human error. However, current thinking has suggested that human error is itself a symptom, rather than a cause, and theories have developed to position the incident-causing human error action as the final link in a much longer chain. This paper presents an exploratory study which sought to examine this theory within a specific context; the construction utilities sector and cable strike incidents. Seven interviews were undertaken with operatives within their work environments, which gathered talk around general safety and cable strike incidents. A thematic approach enabled patterns within the transcribed data to be extracted and contextualized within industry practice. Findings indicated that operatives assigned a variety of different causalities to their experiences of incident occurrence, which were then used to construct a taxonomy of the causal factors of cable strikes from the operatives’ perspective. These factors were then analysed within the industry context to construct potential ‘causal chains’ which are able to link the site incidents to management policy. This study, although exploratory, suggests that application of the systems theory of human error is highly applicable to the construction industry, and that the focus of safety management and safety management research should look beyond operatives on the front line to seek further improvements in safety performance

The challenge of conducting qualitative research to understand the factors that influence equity in medical education: A scoping review

Introduction There are national and international concerns about equity in basic and postgraduate medical education, especially about differential rates of access and attainment across groups of learners. Qualitative research has been increasingly used to understand the factors that influence equity but there are potential limitations to this understanding related to how the research has been conducted. The aim of the scoping review was to identify how qualitative research exploring the factors that influence equity in basic and postgraduate medical education has been conducted. The intention was to inform future research. Methods The electronic databases British Education Index, Campbell Library, CINAHL, Cochrane Library, EMBASE, ERIC, Google Scholar, Health Management Information Consortium (HMIC), MEDLINE, PsycINFO, Web of Science and medical education journals were searched to identify relevant published articles between 2008 and April 2019. Results Among 19,523 articles identified from the literature search, 72 full text articles were included in the review. Most studies had a focus on only one background characteristic and only two studies had a strengths-based focus on individuals. Recommendations for change was at the ‘policy level’ in ten studies and four studies had learner recommendations for change. No studies with a participatory approach were identified. Conclusion The approach to conducting previous qualitative research appears to limit greater understanding of the complexity of factors that influence equity. In response to this challenge, we recommend that future research widen the focus to consider the experiences and strengths of individual learners in addition to those identified by background characteristics. Future qualitative research is recommended to have a broad focus on both the ‘policy level’ and ‘local level’, especially from multiple perspectives. We also recommend greater collaboration of participants with researchers throughout the research process.</p

Persistent Heart Failure Despite Medical Therapy Leading to a Diagnosis of Cardiac Amyloidosis

Cardiac amyloidosis is restrictive cardiomyopathy, commonly classified as either light-chain amyloidosis (AL) or transthyretin amyloidosis (ATTR), which can be further subdivided into wild-type (systemic senile amyloidosis) and hereditary ATTR amyloidosis. Advanced-stage, silent, and clinically undiagnosed amyloidosis has a poor prognosis, with a survival rate of six months and up to five years. We present a 72-year-old female with a past medical history of heart failure, with preserved ejection fraction, atrial fibrillation, systemic lupus erythematosus (SLE), and stage 3b chronic kidney disease, who presented with persistent shortness of breath, lower extremity pitting edema, jugular venous distension, and dyspnea despite optimal medical therapy. The patient was diagnosed with preserved heart failure in the past and was on guideline-directed medical therapy for over five years with no history of cardiac disease in the family. The patient\u27s previous echocardiogram revealed an ejection fraction of 65%. In order to determine the etiology of the patient\u27s cardiomyopathy, she underwent cardiac magnetic resonance imaging (CMR), monoclonal gammopathy testing, and a Technetium pyrophosphate (99mTc-PYP) scintigraphy, of which the latter two were unrevealing. The CMR revealed increased wall thickness and multiple segments of midmyocardial to subendocardial late gadolinium enhancement, suggestive of infiltrative disease. Due to inconclusive testing, the patient underwent an endomyocardial biopsy and was determined to have wild-type, systemic senile amyloidosis, which held a poor prognosis. The patient was started on tafamidis, a new Food and Drug Administration (FDA)-approved therapy for systemic senile amyloidosis, and was discharged on the new medication, with frequent follow-up visits scheduled. Current treatment guidelines for cardiac amyloidosis include loop diuretics and spironolactone. Medications such as beta-blockers, angiotensin-converting enzyme inhibitors, and calcium channel blockers are not clinically effective. There are currently new medications on the horizon, such as tafamidis, which stabilizes the transthyretin tetramer and reduces the formation of amyloid. This case highlighted that patients who have persistent symptoms of heart failure, despite guideline-directed medical therapy, and without a history of genetic cardiac conditions, may also have a diagnosis of cardiac amyloidosis. Cardiac amyloidosis is often misdiagnosed or diagnosed late in the disease course; therefore, there is a need for increasing awareness of early diagnosis and treatment, including new FDA-approved medications for a better chance of survival

Outbreak of dengue fever in Karachi 2006: a clinical perspective

OBJECTIVE: This study reports clinical manifestations and spectrum of severity of dengue fever (DF), dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS) in adult patients admitted during 2006 outbreak in Karachi. A rough estimation of cost of care was also calculated. METHODS: A cross-sectional study was done at a tertiary care hospital in Karachi from January to December 2006. Patients suspected of having DF with positive dengue IgM antibodies were included and records were reviewed. Patients were divided into DF, DHF and DSS as per WHO classification, and the severity of clinical manifestations was determined. RESULTS: A total of 278 (65.72%) of 423 patients admitted with suspected dengue illness had positive IgM titer. Mean age was 31 +/- 12.9 years, with 168 (60%) males and 110 (40%) females. Common presenting symptoms were fever (100%), vomiting (78%), epigastric pain (52%), bleeding tendencies (34%), and erythematous rash (33%). Thrombocytopenia (60%), Leucopenia (45%), elevated transaminases (ALT 71%; AST 88%), and deranged PT (22%) and aPTT (75%) were the predominant. Laboratory parameters: DF was diagnosed in 169 (61%) patients, 82 (29%) were classified as DHF, and 27 (10%) as DSS. Patients with DHF/DSS were younger (n=60, 55%) and had longer hospital stay (p=0.001). Case fatality rate for DHF/DSS group was 4.6%. CONCLUSION: It was estimated that endemicity of DF is on the rise in Karachi and a significant proportion of patients had DHF and DSS. Younger patients develop DHF and DSS and have high case fatality rate

Applying Sport Psychology in Health Professions Education: A Systematic Review of Performance Mental Skills Training

Introduction: Health professionals are expected to consistently perform to a high standard during a variety of challenging clinical situations, which can provoke stress and impair their performance. There is increasing interest in applying sport psychology training using performance mental skills (PMS) immediately before and during performance. Methods: A systematic review of the main relevant databases was conducted with the aim to identify how PMS training (PMST) has been applied in health professions education and its outcomes. Results: The 20 selected studies noted the potential for PMST to improve performance, especially for simulated situations. The key implementation components were a multimodal approach that targeted several PMS in combination and delivered face to face delivery in a group by a trainer with expertise in PMS. The average number of sessions was 5 and of 57 minutes duration, with structured learner guidance, an opportunity for practice of the PMS and a focus on application for transfer to another context. Conclusion: Future PMST can be informed by the key implementation components identified in the review but further design and development research is essential to close the gap in current understanding of the effectiveness of PMST and its key implementation components, especially in real-life situations

How does postgraduate diploma in Family Medicine impact on primary care doctors?

Over the last decade, the emphasis on improving the education and training of family physicians has increased. World Health Organization has also emphasized the importance of a trained primary care workforce. In 2017, Khyber Medical University (KMU) Peshawar initiated a one-year Postgraduate Diploma in Family Medicine for doctors working in primary care, to upgrade their skills and knowledge as Family Physicians. To justify the allocation of resources, there is a need for research on the impact of such programs. This study explores the impact of Diploma in Family Medicine (DFM) on primary care doctors in Khyber Pakhtunkhwa. It also identifies the barriers associated with learning and its translation to practice. A mixed-method explanatory study was conducted from February 2019-2020. Forty-five graduates from the DFM program at KMU were invited to participate in this study. The quantitative data was collected through questionnaires (n=30) and the results were then explained further through qualitative focus group interviews (n=24). Descriptive statistics were calculated for the quantitative data and thematic analysis was performed for the qualitative data. The respondents (n=30/45) were satisfied from the course content and delivery. They agreed that the course is useful (93.3%), relevant to their learning needs (86.7%) and they were able apply it to their clinical practice (100%). The qualitative findings also corroborated that the course improved both the clinical and consultation skills of the participants. The learning environment encouraged them to identify their learning needs and attain new competencies. They reported being more patient-centered and evidence-based, which increased patients' satisfaction. The program also resulted in increased career opportunities and other monetary benefits. Despite the blended nature of the program, the participants found it challenging to balance training with the provision of services. One-year Postgraduate Diploma in Family Medicine is focused, practical and relevant to the learning needs of primary healthcare physicians. The policymakers should consider provision of such training opportunities in both public and private-sector. Future research should explore the long-term impact of such programs on healthcare outcomes

Support for UNRWA's survival

The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) provides life-saving humanitarian aid for 5·4 million Palestine refugees now entering their eighth decade of statelessness and conflict. About a third of Palestine refugees still live in 58 recognised camps. UNRWA operates 702 schools and 144 health centres, some of which are affected by the ongoing humanitarian disasters in Syria and the Gaza Strip. It has dramatically reduced the prevalence of infectious diseases, mortality, and illiteracy. Its social services include rebuilding infrastructure and homes that have been destroyed by conflict and providing cash assistance and micro-finance loans for Palestinians whose rights are curtailed and who are denied the right of return to their homeland

TRANSFORM (Multicenter Experience With Rapid Deployment Edwards INTUITY Valve System for Aortic Valve Replacement) US clinical trial: Performance of a rapid deployment aortic valve

Background: The TRANSFORM (Multicenter Experience With Rapid Deployment Edwards INTUITY Valve System for Aortic Valve Replacement) trial (NCT01700439) evaluated the performance of the INTUITY rapid deployment aortic valve replacement (RDAVR) system in patients with severe aortic stenosis. Methods: TRANSFORM was a prospective, nonrandomized, multicenter (n 1�4 29), single-arm trial. INTUITY is comprised of a cloth-covered balloon- expandable frame attached to a Carpentier-Edwards PERIMOUNT Magna Ease aortic valve. Primary and effectiveness endpoints were evaluated at 1 year. Results: Between 2012 and 2015, 839 patients underwent RDAVR. Mean age was 73.5 8.3 years. Full sternotomy (FS) was used in 59% and minimally invasive surgical incisions in 41%. Technical success rate was 95%. For isolated RDAVR, mean crossclamp and cardiopulmonary bypass times for FS were 49.3 26.9 minutes and 69.2 34.7 minutes, respectively, and for minimally invasive surgical 63.1 25.4 minutes and 84.6 33.5 minutes, respectively. These times were favorable compared with Society of Thoracic Surgeons data- base comparators for FS: 76.3 minutes and 104.2 minutes, respectively, and for minimally invasive surgical, 82.9 minutes and 111.4 minutes, respectively (P<.001). At 30 days, all-cause mortality was 0.8%; valve explant, 0.1%; throm- boembolism, 3.5%; and major bleeding, 1.3%. In patients with isolated aortic valve replacement, the rate of permanent pacemaker implantation was 11.9%. At 1 year, mean effective orifice area was 1.7 cm2; mean gradient, 10.3 mm Hg; and moderate and severe paravalvular leak, 1.2% and 0.4%, respectively
