Creating the Foundation of a Healthcare Research Project

The research topic of this paper develops a case study approach that builds on the foundations of Yin＇s ＂linear model＂ and ＂the best practice＂ used in theoretical case studies at international research literature. It discusses the case study method and its role and focusing on research questions like healthcare branding, research design, and methodic. Also presents the case study research theory for a research case study. The methods used in this paper are based on hypothesis of a generic hospital branding strategy for the Romanian Private Hospital and also may apply to the Romanian strategy of development of public healthcare entities and partnerships between public and private healthcare entities. An empirical test of the relationships among branding loyalty and awareness, customer satisfaction, trust and relationship commitment suggests that Romanian hospitals can be successful in creating an image and positive brand equity if they can manage their customer relationships well. This can be done through a coordinated strategy of management and marketing development of healthcare entities. The results highlight the dominance of case-study research in qualitative marketing healthcare and highlight the importance of customer relationships in the branding practice of healthcare marketing. It also shows that marketing managers can succeed in creating positive brand equity and image if they can manage relationships with their customers well.

Case studies in psychotherapy training using Austria as an example

BACKGROUND Case studies(CS)are relevant for the development of theoretical and practical competencies in psychotherapy.Despite rapid progress in the development of methods and principles for establishing CS in the last three decades,research into the aims of CS,especially in training,or how CS are to be conducted is rare.AIM To elucidate the form and methodology of CS,the objectives of CS used in training institutions(TI),and if/how TIs handle therapist allegiance.Also,this preliminary investigation will suggest avenues for further research and attempt to establish certain guidelines.METHODS In order to counteract researcher bias and enlarge the question-pool,a focus group was established.The recorded and transcribed text was analyzed with Mayring’s method of qualitative content analysis,and the generated categories were formulated as questions.The resulting questionnaire with both qualitative and quantitative queries was sent out(after pre-testing)to all 39 Austrian TIs that provide professional psychotherapy training.The answers and text passages received were then also categorized with qualitative content analysis.Data analysis was discussed by a peer group consisting of three psychotherapists trained in differing schools of psychotherapeutic methods.RESULTS 94%of Austrian institutes use CS as part of their psychotherapeutic training.Understanding of the term“case study”is inconsistent and has a wide variety of interpretations.CS serve mainly:(1)For observation of training/progress in therapeutic practice and knowledge/acquisition of the theory specific to each psychotherapeutic school;(2)To improve(self-)reflection capabilities;and(3)To expand theoretical knowledge.Most of the CS written are not accessible for students nor for the research community.More than two thirds of the CS take only the position of the author into account(the client’s position is not described).15.5%of the TIs do not consider researcher or therapist allegiance at all.CONCLUSION A more precise formulation of the term case study is needed in psychotherapeutic training.The training therapists play a key function,as they exemplify and teach how to deal with distorting factors.General guidelines as to how to conduct CS in training institutions would provide more direction to students,increase scientific rigor,and enhance synergistic effects.

Role of ammonia in predicting the outcome of patients with acuteon- chronic liver failure

BACKGROUND High venous ammonia(VA)values have been proven to be a part of the mechanism of hepatic encephalopathy in patients with liver cirrhosis(LC)as well as acute hepatitis.Moreover,VA has been associated with poor prognosis and high mortality in these clinical settings.However,the role of ammonia in acuteon-chronic liver failure(ACLF)has not yet been clearly established.AIM To assess the role of VA in predicting the outcome of cirrhotic patients with ACLF in a tertiary care center.METHODS We performed a retrospective observational study including consecutive patients with LC hospitalized for acute non-elective indications such as ascites,hepatic encephalopathy(HE),upper gastrointestinal bleeding,or bacterial infections that fulfilled the Asian Pacific Association for the Study of the Liver(APASL)criteria for ACLF.The study was conducted in“St.Spiridon”University Hospital,Iasi,Romania,a tertiary care center,between January 2017 and January 2019.The APASL ACLF Research Consortium(AARC)score was calculated and ACLF grade was established accordingly.West-haven classification was used for HE.Statistical analysis was performed using IBM SPSS version 22.0.RESULTS Four hundred and forty-six patients were included,aged 59(50-65)years,57.4%men.Child-Pugh,model for end-stage liver disease(MELD)and AARC scores were 11(10-12),19.13±6.79,and 7(6-8),respectively.66.4%had ACLF grade I,31.2%ACLF grade II,and 2.5%ACLF grade III.HE was diagnosed in 83.9%,34%grade I,37.2%grade II,23.5%grade III,and 5.3%grade IV.Overall mortality was 7.8%.VA was 103(78-148)μmol/L.Receiver operating characteristic analysis showed good accuracy for the prediction of in-hospital mortality for the AARC score[Area under the curve(AUC)=0.886],MELD score(AUC=0.816),VA(AUC=0.812)and a fair accuracy for the Child-Pugh score(AUC=0.799).Subsequently,a cut-off value for the prediction of mortality was identified for VA(152.5μmol/L,sensitivity=0.706,1-specificity=0.190).Univariate analysis found acute kidney injury,severe HE(grade III or IV),VA≥152.5μmol/L,MELD score≥22.5,Child-Pugh score≥12.5,and AARC score≥8.5 to be associated with inhospital mortality.Multivariate analysis identified AARC score≥8.5 and venous ammonia≥152μmol/L to be independent predictors of in-hospital mortality.CONCLUSION VA could be used as an inexpensive predictor of in-hospital mortality in patients with ACLF.Patients with both ACLF and VA>152.5μmol/L have a high risk for a poor outcome.

Governance of decentralized autonomous organizations that produce open source software

Decentralized autonomous organizations(DAOs)have found use in the governance of open source software(OSS)projects.However,the governance of an OSS producing DAO should match the particularities of OSS production while also overcoming the existing challenges of decentralized governance.The existing decentralized governance frameworks do not include all the governance activities of OSS projects.Therefore,this study presents a governance framework for DAOs that produce OSS.The framework is built upon a total of 34 articles on DAO and OSS governance.The framework was evaluated in three leading DAOs that produce OSS.The evaluation underscores the significance of the framework and proves the potential of the systematic categorization of governance mechanisms.Finally,we list emerging governance practices in various governance domains in this developing field.

A decision model for decentralized autonomous organization platform selection: Three industry case studies

Context:Decentralized autonomous organizations are a new form of smart contract-based governance.Decentralized autonomous organization platforms,which support the creation of such organizations,are becoming increasingly popular,such as Aragon and Colony.Selecting the best fitting platform is challenging for organizations,as a significant number of decision criteria,such as popularity,developer availability,governance issues and consistent documentation of such platforms,should be considered.Additionally,decision-makers at the organizations are not experts in every domain,so they must continuously acquire volatile knowledge regarding such platforms.Objective:Supporting decision-makers in selecting the right decentralized autonomous organization platforms by designing an effective decision model is the main objective of this study.We aim to provide more insight into their selection process and reduce time and effort significantly by designing a decision model.Method:This study presents a decision model for the decentralized autonomous organization platform selection problem.The decision model captures knowledge regarding such platforms and concepts systematically.This model is based on an existing theoretical framework that assists software engineers with a set of multi-criteria decision-making problems in software production.Results:We conducted three industry case studies in the context of three decentralized autonomous organizations to evaluate the effectiveness and efficiency of the decision model in assisting decision-makers.The case study participants declared that the decision model provides significantly more insight into their selection process and reduces time and effort.Conclusion:We observe in the empirical evidence from the case studies that decision-makers can make more rational,efficient,and effective decisions with the decision model.Furthermore,the reusable form of the captured knowledge regarding decentralized autonomous organization platforms can be employed by other researchers in their future investigations.

Innovations in maternal and child health:case studies from Uganda

Background:Nearly 300 children and 20 mothers die from preventable causes daily,in Uganda.Communities often identify and introduce pragmatic and lasting solutions to such challenging health problems.However,little is known of these solutions beyond their immediate surroundings.If local and pragmatic innovations were scaled-up,they could contribute to better health outcomes for larger populations.In 2017 an open call was made for local examples of community-based solutions that contribute to improving maternal and child health in Uganda.In this article,we describe three top innovative community-based solutions and their contributions to maternal health.Main text:In this study,all innovations were implemented by non-government entities.Two case studies highlight the importance of bringing reproductive health and maternal delivery services closer to populations,through providing accessible shelters and maternity waiting homes in isolated areas.The third case study focuses on bringing obstetric imaging services to lower level rural health facilities,which usually do not provide this service,through task-shifting certain sonography services to midwives.Various health system and policy relevant lessons are highlighted.Conclusions:The described case studies show how delays in access to health care by pregnant women in rural communities can be systematically removed,to improve pregnancy and delivery outcomes.Emphasis should be put on identification,capacity building and research to support the scale up of these community-based health solutions.
