Normalizing Heterogeneous Medical Imaging Data to Measure the Impact of Radiation Dose

The production of medical imaging is a continuing trend in healthcare institutions. Quality assurance for planned radiation exposure situations (e.g. X-ray, computer tomography) requires examination-specific set-ups according to several parameters, such as patient’s age and weight, body region and clinical indication. These data are normally stored in several formats and with different nomenclatures, which hinder the continuous and automatic monitoring of these indicators and the comparison between several institutions and equipment. This article proposes a framework that aggregates, normalizes and provides different views over collected indicators. The developed tool can be used to improve the quality of radiologic procedures and also for benchmarking and auditing purposes. Finally, a case study and several experimental results related to radiation exposure and productivity are presented and discussed.     

Moving health professionals as an alternative to moving patients: The contribution of overseas visiting medical specialists to the health system in Malta

Cross-border healthcare has become a major policy issue in the past years across the European Union. Professional mobility, as a means of providing specialised health services has not been given sufficient attention in both the research and policy agendas. This paper presents a case study of the contribution made by visiting overseas medical specialists to the health system in Malta. Twenty-five semi-structured interviews were conducted. A grounded theory approach was utilised in view of the limited amount of literature available on the subject. Qualitative content analysis revealed one superordinate theme, being the value of the service, and three further subthemes, which include the quality of the service provided, its longevity and durability, as well as the critical contributions of expatriates. The service is an integral component of the local health service. This study makes an important contribution to the literature on cross-border healthcare. Lessons learnt may be transferable to other small island states and territories. The European Reference Networks being developed at EU level may need to focus more on the benefits that can accrue through short term professional mobility than has been the case to date. The findings also serve to propose several important features that need to be in place to increase the chances of longevity, sustainability, quality and cost effectiveness in cross border health care services.     

Validation of the Expressions of Moral Injury Scale‐Military version‐Short Form

Military personnel may encounter morally injurious events that lead to emotional, social, and spiritual suffering that transcend and/or overlap with mental health diagnoses (e.g., post‐traumatic stress disorder [PTSD]). Advancement of scientific research and potential clinical innovation for moral injury (MI) requires a diversity of measurement approaches. Drawing on results from the bifactor model in Currier et al.'s (2017) psychometric evaluation of the Expressions of Moral Injury Scale‐Military version (EMIS‐M), this study validated a four‐item short form of the instrument with two samples of veterans with a history of war‐zone service. Namely, despite the reduced number of items, the EMIS‐M‐Short Form (SF) yielded favourable internal consistency and comparable levels of convergent validity with theoretically related constructs (e.g., PTSD and struggles with morality and ultimate meaning) as the full‐length version. Notwithstanding the possible utility of distinguishing between self‐ and other‐directed forms of MI, factor analytic results further revealed that the EMIS‐M‐SF was best conceptualized with a unidimensional factorial model that might allow for a general assessment of MI‐related outcomes. Overall, these initial results suggest that the EMIS‐M‐SF may hold promise as a short, reliable, and valid assessment of overall outcomes related to a possible MI.

The design and psychometric evaluation of the emergency medical services resilience scale (EMSRS)

IntroductionThe nature of pre-hospital emergency medical care can expose healthcare workers to significant stresses that might lead to psychological problems such as job burnout and impaired resilience. A valid and reliable tool is, therefore, needed to investigate resilience in emergency medical services (EMS) personnel. This study was conducted to design a tool for assessing the resilience of emergency medical personnel in Iran and to examine the psychometric properties of the designed tool.MethodsThis methodological study was conducted in two phases: A qualitative stage with individual interviews and a review of literature to generate items, and a quantitative stage of psychometric evaluations that assessed the face, content, and construct validity of the tool. The reliability of the tool was also assessed using the internal consistency and test-retest methods.ResultsExploratory factor analysis was used to design a 31-item scale with a six-factor structure. These six factors, i.e. job motivation, communication challenges, social support, remaining calm, self-management, and consequences of stress, explained 51.8% of the variance. The scale’s Cronbach's alpha coefficient and intraclass correlation coefficient were calculated as 0.91 and 0.85, respectively.ConclusionThe scale developed on the resilience of EMS personnel can be used as a valid and reliable tool for assessing resilience in EMS personnel. It can also assist emergency service managers to plan courses to improve their staff’s resilience.     

国外家庭医生签约服务及其对我国的启示

本研究在总结英国、美国、德国、澳大利亚等国家的家庭医生签约服务现状及其经验的基础上,结合我国在家庭医生签约过程中存在的问题,提出针对性的解决措施或建议。鉴于缺乏相关制度保障、财政支持不到位、家庭医生能力不足,未建立良好医患关系等问题,本研究指出应强化相关政策倾斜力度、增加相关经费投入、加强家庭医生队伍建设、建立良好医患关系等,探索适合中国特色的家庭医生签约服务模式。
