It’s the Culture!—How systemic and societal constructs impact well‐being

Pediatric anesthesiologists practice within a culture, a system, and a society. In this article, we provide an overview of the influence these have on the well‐being or the unwellness of pediatric anesthesiologists. The scope of these issues is broad and far‐reaching; thus, our goal has been to highlight those areas which would be likely to have the largest impact on well‐being if addressed fully by society, institutions, and leaders in our field. We discuss the burnout‐promoting aspects of medical education and training. We survey occupational factors, such as the high‐stake pediatric anesthesia environment, occupational health hazards, time pressure, and the reduction in physician autonomy. We then describe societal barriers, such as the marginalization of certain populations, the US system of malpractice litigation, the stigma surrounding psychiatric care, and some of the issues related to physician reimbursement in the United States. We conclude that in order to move forward, improving physician wellness must be a focus of society, of the medical system as a whole, and of individual departments and leaders in pediatric anesthesia.     

Distal oblique osteotomy versus cheilectomy for moderate-advanced hallux rigidus: A 2-year propensity-score-matched study

BackgroundThe surgical treatment of moderate-advanced hallux rigidus is controversial. Cheilectomy is widely used but has recurrence rates of up to 30%. Dorsal oblique metatarsal osteotomy (DOO) has also shown good results, however, there is no study comparing outcomes of the DOO against cheilectomy.MethodsThis was a retrospective propensity score matched study based on registry data from a single tertiary institution. Between 2007 and 2017, all patients who had undergone dorsal cheilectomy or DOO for hallux rigidus were included. Patients with previous foot surgery, revision surgeries, and concomitant surgical procedures were excluded. Clinical outcomes, complication rates, revision rates and patient satisfaction were assessed at 2 years postoperatively.ResultsThere were 44 patients (34 cheilectomy, 10 DOO). After propensity score matching, 17 cheilectomy and all 10 DOO cases were selected for comparison. Patients in both groups had a significant improvement in visual analogue pain scores (VAS) and AOFAS 1st toe scores 2-years post-operatively (P < 0.001) with high levels of post-operative satisfaction (85.1%). Overall there were no statistically significant differences in post-operative scores, improvement in scores, complication rates, revision rates, and levels of patient satisfaction between groups.ConclusionsBoth the DOO and cheilectomy give similarly good outcomes for moderate-advanced hallux rigidus. Further studies are needed to elucidate differences in indications for each procedure.     

A prospective longitudinal study of chronic abdominal pain and symptoms after sleeve gastrectomy

BackgroundSleeve gastrectomy (SG) is widely applied. Few studies have evaluated patient-reported abdominal symptoms after SG.ObjectiveTo evaluate the prevalence of chronic abdominal pain (CAP) and symptom characteristics after SG.SettingOslo University Hospital and Voss Hospital.MethodsWe performed a longitudinal prospective cohort study of patients operated on with SG at two tertiary referral centers. For broad assessments of abdominal pain and symptoms, consultations were performed and questionnaires retrieved before and 2 years after SG. The definition of CAP or recurrent abdominal pain lasting for more than 3 months was sustained. Preoperative predictors of CAP were explored.ResultsOf 249 patients at baseline, 207 (83.1%) had follow-up consultations. Mean preoperative body mass index was 43.9 (6.0) kg/m², and 181 patients (72.7%) were female. Total weight loss was 31.9% (10.4%). CAP was reported in 32 of 223 patients (14.3%) before and in 50 of 186 patients (26.9%) after SG (P =.002). All mean gastrointestinal symptoms rating scale questionnaire scores increased after SG, and they were higher in patients with CAP. Symptoms of depression decreased but were more prevalent in patients with CAP at follow-up. Most quality-of-life scores increased after SG. However, patients with CAP had lower scores (except for physical functioning). Preoperative bothersome Gastrointestinal Symptom Rating Scale reflux symptoms, study center, and younger age seemed to predict CAP after SG.ConclusionThe prevalence of patient-reported CAP increased after SG. Patients reporting CAP had reduced quality-of-life scores.     

Association between Osteoporotic Vertebral Compression Fractures and Age,Bone Mineral Density,and European Quality of Life-5 Dimensions in Korean Postmenopausal Women: A Nationwide Cross-sectional Observational Study

BackgroudThe purpose of this study was to investigate the characteristics of osteoporotic vertebral compression fractures (OVCFs) in Korean postmenopausal women and the association between OVCFs and clinical factors such as age, bone mineral density (BMD), and quality of life.MethodsAccording to the population distribution in four regions in Korea, 1,281 postmenopausal female patients were recruited from nationwide orthopedic outpatient clinics. Radiologic, asymptomatic, and within 3 months of OVCF groups were analyzed based on age, fracture location, and prevalence according to BMD. In addition, BMD, T-score, body mass index, and European Quality of Life-5 Dimensions (EQ-5D) were investigated in the three groups, and the differences between groups were compared and analyzed.ResultsThe prevalence of radiologic OVCFs at the T11–L1 was 3.7 times higher in the 70s group (44.0%) than in the 50s group (11.9%). Femur and total hip BMD were significantly lower in patients with thoracolumbar junction fractures than in patients with L2–5 fractures, whereas no difference was observed in lumbar spine BMD. Of the three OVCF groups, the within 3 months of OVCF group had the lowest lumbar spine T-score of −2.445. The asymptomatic OVCF group also showed significantly lower lumbar spine T-score than did the group without radiologic OVCFs (p < 0.001). The EQ-5D showed a significant decrease in the radiologic OVCF group (p < 0.001) and within 3 months of OVCF group (p < 0.001).ConclusionsThe prevalence of OVCFs in the thoracolumbar junction rapidly increases with old age and low BMD in Korean postmenopausal women. Femur and total hip BMD are more predictive of thoracolumbar junction fractures than lumbar spine BMD. Patients with radiologic OVCFs had a significantly lower quality of life than no OVCF group. Therefore, this study shows it is important to treat and prevent osteoporosis before an OVCF occurs.     

Concentrating stroke care provision in the Czech Republic: The establishment of Stroke Centres in 2011 has led to improved outcomes

This article describes policy processes that have led to the re-organisation of stroke care in the Czech Republic since 2011, which has been part of a broader process of care concentration in several medical fields. Currently, stroke care is provided by 13 Comprehensive and 32 Primary Stroke Centres. The paper explains factors that supported the reform implementation, reviews implications, and discusses future challenges.Mandatory reporting of quality indicators, the introduction of a benchmarking system, integration with pre-hospital emergency care, and the introduction of countrywide patient triage have supported more timely treatment for stroke patients and better quality of care. Data from the Stroke Care Quality Indicators of the Czech Stroke Society show positive trends in many areas: the number of patients treated with intravenous thrombolysis quadrupled in eight years, with 26.4 % of all acute stroke patients receiving thrombolysis in 2018. Czech Republic now ranks third in Europe in the number of thrombolysis per population and second in the number of mechanical thrombectomies per population. The Czech experience provides an example of positive outcomes of concentrated stroke care, while highlighting the importance of proper implementation processes. In particular, it is essential to involve stakeholders and to provide reputational incentives through continuous benchmarking.     

Effects of participatory workplace improvement program on stress-related biomarkers and self-reported stress among university hospital nurses: a preliminary study

Although participatory workplace improvement programs are known to provide favorable effects on high stress occupations like nursing, no studies have confirmed its effect using biomarkers. The aim of this study was to determine whether a participatory workplace improvement program would decrease stress-related symptoms as evaluated by biomarkers and self-reported stress among hospital nurses. Three actions to alleviate job stress, which were determined through focus group interviews and voting, were undertaken for two months. A total of 31 female Japanese nurses underwent measurement of inflammatory markers, autonomic nervous activity (ANA), and perceived job stress (PJS) at three-time points; before the program (T1), within a week after the completion of the program (T2), and three months after the program (T3). A series of inflammatory markers (Interferon-γ, Interleukin (IL)-6, and IL-12/23p40) decreased significantly at T2, and IL-12/23p40 and IL-15 significantly decreased at T3 compared to T1, while ANA and PJS remained unchanged. Our participatory program exerted beneficial effects in reducing inflammatory responses, but not for ANA and PJS. Further investigations with a better study design, i.e., a randomized controlled trial, and a larger sample size are warranted to determine what exerted beneficial effects on inflammatory markers and why other outcomes remained unchanged.
