Background: Rising health care costs, coupled with an emphasis on cost containment, continue to gain importance. Surgeon cost scorecards developed to track case-based expenditures can help surgeons compare themselves with their peers and identify areas of potential quality improvement. Purpose: We sought to investigate what effect surgeon scorecards had on operating room (OR) costs in orthopedic surgery. Methods: Our hospital distributed OR cost scorecards to 4 adult reconstruction fellowship-trained orthopedic surgeons beginning in 2012. The average direct per-case supply cost of procedures was calculated quarterly and collected over a 5-year period, and each surgeon’s data were compared with that of their peers. All 4 surgeons were made aware of the costs of other surgeons at the 2-year mark. The initial 2 years of data was compared with that of the final 2 years. Results: The average direct per-case supply cost ranged from $4955 to $5271 for total knee arthroplasty (TKA) and $5469 to $5898 for total hip arthroplasty (THA) during the initial 2-year period. After implementing disclosures, the costs for TKA and THA, respectively, ranged from $4266 to $4515 (14% annual cost savings) and from $5073 to $5727 (5% annual cost savings); 3 of the 4 surgeons said that cost transparency altered their practice. Conclusion: Our comparison suggests that orthopedic surgeons’ participation in a program of operative cost disclosure may be useful to them; we found a possible association with reduced per-case costs for TKA and THA at our institution over a 5-year period. More rigorous study that incorporates the effects of the scorecards on patient outcomes is warranted.

Study background Back injuries are common among nurses worldwide with lifetime prevalence of lower back pain ranging from 35% to 80%, making nursing a profession at great risk for back injuries. Purpose This systematic scoping review explored and mapped existing evidence regarding the prevention of low back injury and pain among nurses and nursing students. Methods Using a scoping review methodology, six databases were searched initially in September 2017 and updated June 2020. Studies investigating interventions designed to reduce back injuries and pain among regulated nurses and student nurses, published in peer-review journals and written in English, were eligible for inclusion in this review. Quantitative, qualitative, and mixed methods studies of regulated nurses, nursing students, and nursing aides were included. Two independent reviewers screened, critically analysed studies using a quality appraisal tool, extracted data, and performed quality appraisals. Results Two searches yielded 3,079 abstracts and after title, abstract and screening, our final synthesis was based on 48 research studies. Conclusions Forty years of research has demonstrated improvements in quality over time, the efficacy of interventions to prevent back injury and pain remains unclear, given the lack of high-quality studies. Further research, using multi-dimensional approaches and rigorous study designs, are needed.


As the Sultanate of Oman in the process of uses e-services among public services by adopting of technological implication in the services of the government in recent time. Therefore, it is a timely initiative to develop a conceptual framework between the e- service, digital transformations attributes and efficiency of the digital transformation, Oman. In order to development of conceptual model study examined review of literature on about the effectiveness of electronic services and digital transformation in the selected public sector in the Sultanate of Oman. The study used online empirical sources in the names of organizational, technology, environment and human resource factors, as well as the effectiveness of digital change in various online database sources such as Google Scholars, Springer Link, Wiley, Science Direct, JSTOR, Emerald Full text, Scopus and EBSCO HOST, etc. The study review results show that organizational, technological, environmental and human factors play an important role in ensuring the effectiveness of the public sector in the digital transformation in the Sultanate of Oman. The study also found that there is mediating role of E-service in the relationship between digital transformations attributes and the digital transformation. Based on the summary of literature review, the study provides guidance for the future scope of empirical research and develop a conceptual framework between the e- service, digital transformations attributes and efficiency of the digital transformation to conduct a rigorous study in Oman and its regions.

Abstract. Background: This PRISMA scoping review explored worldwide research on family-based treatments for suicide prevention. Research on this topic highlights the importance of facilitating familial understanding of a suicidal individual. Aim: The review sought evidence of outcomes of trials in which both the patient and family member in the intervention arm attended the same sessions at which suicide was openly discussed. Method: To explore this topic, the authors searched for randomized and nonrandomized controlled trials using Medline (Ovid), PsycINFO (Ovid), Social Services Abstracts (EBSCO), and Web of Science on July 8, 2020. Results: Ten different studies were included that spanned five treatment modalities. Specifically, of the interventions in these 10 articles, 40% employed some sort of cognitive-behavioral therapy, 20% examined attachment-based family therapy, 20% used family-based crisis intervention, and the remaining 20% were distinct interventions from one another. Additionally, several of these articles demonstrated rigorous study methodology and many of the articles reported significant improvements in suicidal ideation or behaviors. Conclusion: Several important research gaps were identified. While this approach has been largely understudied, and to date has been primarily researched in adolescent populations, family interventions have great potential for treatment and prevention of suicidality.

Background: Patients with a history of venous thromboembolism (VTE) undergoing total knee arthroplasty (TKA) are at a high risk of postoperative VTE. Purpose: In this high-risk population, we sought to evaluate the safety and efficacy of multimodal thromboprophylaxis. The regimen consisted of discontinuation of procoagulant medications, VTE risk stratification, regional anesthesia, rapid mobilization, perioperative use of pneumatic compression devices, vigorous ankle dorsiflexion during the recovery period, and chemoprophylaxis tailored to the patient’s risk of VTE. Methods: We conducted a retrospective chart review of 141 consecutive patients with a history of VTE who underwent 177 elective TKA procedures between 2005 and 2019 by 2 arthroplasty surgeons at a single institution. The patients had a history of deep venous thrombosis (DVT) (n = 127; 72%), pulmonary embolism (PE) (n = 20; 11%), or both (n = 30; 17%). Postoperative chemoprophylaxis included aspirin (n = 20; 11%), anticoagulation (n = 135; 77%), or a combination of aspirin and anticoagulation (n = 21; 12%). Complications within 120 days, including VTE events, wound complications, bleeding, and unplanned readmissions, were recorded, as was 1-year mortality. Results: Five patients (2.8%) developed symptomatic DVT (3 distal, 2 proximal), and 4 patients (2.3%) developed symptomatic PE. The most common postdischarge complications were wound infection (n = 6; 3.4%) and stiffness requiring manipulation under anesthesia (n = 5; 2.8%). There was 1 emergency room visit and 13 unplanned readmissions; 3 patients developed intra-articular hematomas or prolonged wound drainage and recovered uneventfully. All patients were alive 1 year after surgery. Conclusion: The findings of this retrospective study suggest that multimodal prophylaxis may be safe and effective in patients with a history of VTE undergoing primary and revision TKA. More rigorous study is warranted.

Introduction: Non-adherence to inhaled corticosteroids (ICS) in children with asthma leads to significant morbidity and mortality. Few interventions to improve adherence have been effective and little is known about what contributes to intervention effectiveness. This systematic review summarises the efficacy of these interventions and the characteristics of effective interventions to inform future studies aiming to improve adherence to ICS in children with asthma. Methods: PubMed, Embase, PsychINFO, Medline, Web of Science, and International Pharmaceutical Abstracts were systematically searched on the 3rd of October 2020 for randomised control trials measuring adherence to ICS in children with asthma. A narrative synthesis was conducted focusing on intervention efficacy and study reliability. Intervention content was coded based on the NICE guidelines for medicines adherence (The Perceptions and Practicalities Approach, PAPA) and Behaviour Change Techniques (BCT), to determine the effective aspects of the intervention. Results: Of 240 studies identified, 25 were eligible for inclusion. Thirteen of the twenty-five studies were categorised as being highly reliable. Nine of the thirteen studies were effective at increasing adherence and six of those met the criteria for a PAPA intervention. Conclusion: Adherence interventions in children with asthma have mixed effectiveness. Effective studies tended to be of higher quality, were tailored to individuals perceptual and practical adherence barriers, and used multiple BCTs. However, due to the small number of included studies and varying study design quality, conclusions drawn here are preliminary. Future research is needed to test a PAPA-based intervention with a rigorous study design as outlined in this review

Background: Rigorous study of ventricular fibrillation (VF) is not feasible in humans. The spatiotemporal characteristics of prolonged VF remain undefined, limiting our understanding of this lethal rhythm. Methods: VF was mapped in 4 canines. The endocardial and epicardial left ventricle (LV) and right ventricle (RV) were sequentially mapped at 0 to 15, 15 to 30, 30 to 45, and 45 to 60 minutes post-induction. Ten consecutive beats were used to determine average cycle length and regularity index of ventricular and His-Purkinje system signals in discrete regions during each time interval. Results: Average VF time was 58±12 minutes. The shortest ventricular cycle length was present in the RV apical region (70±10 msec) at 0 to 15 minutes and at 15 to 30 minutes (89±31 msec) and LV apical region at 45 to 60 minutes (242±163 msec). The His-Purkinje system cycle length was the shortest at the RV outflow tract (75±3 msec) at 0 to 15 minutes, RV inflow and free wall (89±12 msec) at 15 to 30 minutes, LV apical region (83±14 msec) at 30 to 45 minutes, and inferior and inferolateral LV (145±23 msec) at 45 to 60 minutes. Regularity index was the highest in the RV inflow and free wall (78%) at 0 to 15 minutes, RV apical region (86%) at 15 to 30 minutes, LV septum and epicardial anterior RV (80%) at 30 to 45 minutes, and anterior and anterolateral LV (75%) at 45 to 60 minutes. Conclusions: These data suggest significant regional changes in electrical activity throughout VF in canines. A transition of fastest electrical activity from RV to LV apical regions across VF was observed. Further studies are warranted to confirm the above findings.

One of the most challenging problems during disasters involving crowds is pedestrian evacuation. It is very important in such situations to improve survival rates by getting all or most of the people out in the shortest possible time. Technological intervention through augmenting the evacuation process using an unmanned aerial vehicle (UAV) exhibits great potential in improving survival rates, but the exploration of this method is still in its infancy. Therefore, this study explores the potential of utilizing UAVs for crowd management during emergency evacuations. We conducted a rigorous study, using a simulation model featuring four UAVs and differing numbers of pedestrians, with use of two UAV guidance approaches: partial guidance and full guidance. The experimental results suggest that exploiting UAVs in crowd evacuation and following the partial guidance approach can lead to a more efficient evacuation process.

In this paper the Modified Routh Approximation (MRA) and Affine Arithmetic (AA) methods are investigates for obtaining the reduced order model (ROM) of SISO, discrete & MIMO uncertain systems into lower order system. Rigorous study and analysis of physical system direct to the outcome of systems with uncertainty instead of certain coefficients. Thus, systems having uncertain but bounded parameters known as uncertain systems are under consideration in this paper. An effective algorithm to determine the reduced order model is proposed here. This proposed methodology is verified using numerical examples available from the literature.

This chapter reviews the breakthrough discovery of the complete sequence of human DNA in 2003, which rapidly ushered in an era of genomics and big data. It discusses “precision medicine,” which refers to the notion of accounting for individual variability in genes, environment, and lifestyle to devise new ways to prevent, detect, diagnose, and treat health conditions. It also describes “precision public health” as the related effort to use individual variability to more finely tailor preventive interventions for at-risk groups and improve population health. The chapter addresses scientific questions about the roles of genes, environmental, gene–gene, and gene–environment interactions in human health through the rigorous study of genotypic, phenotypic, and environmental data in human populations. It tackles the genomic contributions to health and disease, such as the assessment of whether diseases and gene variants show correlated transmission among related individuals.
