Introduction: Usability of computer systems, and satisfaction of their users, has been related to user performance, especially for clinical decision support systems (CDSS). The purpose of this paper is to present an evaluation of satisfaction and usability of a web-based CDSS called HADA. HADA was developed to improve antenatal healthcare by assisting in obstetric risk assessment. Methods: This research used an observational study of blocks of user interactions with multiple treatments. Twenty physicians of two rural hospitals were HADA was tested performed eleven independent tasks, using it. Subjects answered the NASA TLX self-assessment questionnaire1 after performing each task. Once they finished the set of tasks, they answered the Post-Study System Usability Questionnaire (PSSUQ) 2,3. Results: The data was not normally distributed; therefore non-parametric approaches were used for analysis. Workload was measured to be low and satisfaction to be high. Main tasks related to CDSS scored in the lowest range of findings. There was a statistically significant difference of Overall NASA TLX cognitive load medians between tested users at both hospitals. Median differences among types of physicians were not statistically significant. PSSUQ results showed a high overall acceptance. System usefulness was highest on the independent subscales, followed by interface quality and then information quality. Discussion: Experiences of users does not seem to be a factor that affected user evaluations of HADA. The reduction on workload on similar tasks suggested a learning effect. HADA's match to current workflow seems to be a factor in perception of workload and acceptance of the tool. The users at the hospital that had no comparable processes experienced a higher workload and lower acceptability. Conclusions: HADA proved to be a tool that generally results in low additional workload for clinicians independent of their experience, and is rated high in acceptability. The design and development techniques used for HADA have resulted in a tool with low workload and high acceptability. The evaluation methods used have proven useful in this clinical system context and confirm previous research that usability of computer systems, user satisfaction levels and user performance, are related.

This study examines opinion leadership in informal political conversations. Theoretically, the social psychological perspective on opinion leadership is refined and the goals-plans-action model (Dillard, 1990) is applied to opinion leadership in everyday political conversations. Survey and observational data on conversations of 78 dyads of friends and acquaintances reveal that opinion leadership comes along with the goal to influence, with argument-based opinion giving, and with effects on conversation partner's opinions. Moreover, results indicate that opinion leadership in political conversations structurally resembles a strategic influence process guided by the goal to influence. By generating concrete findings on communicative influence, this study closes an important academic void of opinion leadership research and provides relevant insights into the political negotiation process.

A variety of data models have been developed to provide a standardized data interface that supports organizing clinical research data into a standard structure for building the integrated data repositories. HL7 Fast Healthcare Interoperability Resources (FHIR) is emerging as a next generation standards framework for facilitating health care and electronic health records-based data exchange. The objective of the study was to design and assess a consensusbased approach for harmonizing the OHDSI CDM with HL7 FHIR. We leverage a FHIR W5 (Who, What, When, Where, and Why) Classification System for designing the harmonization approaches and assess their utility in achieving the consensus among curators using a standard inter-rater agreement measure. Moderate agreement was achieved for the model-level harmonization (kappa=0.50) whereas only fair agreement was achieved for the property-level harmonization (kappa=0.21). FHIR W5 is a useful tool in designing the harmonization approaches between data models and FHIR and facilitating the consensus achievement. [ABSTRACT FROM AUTHOR]

This paper presents an observational study conducted at the public environment investigating children's engagement with a social robot within a pretend play scenario. A pretend play system was designed in order to address the challenges of evaluating child-robot interaction by exploiting the advantages of ubiquitous robotics and ambient intelligence of multimodal, multi-sensory perception. The system performed successfully at a children's play centre where a humanoid NAO robot was able to dynamically adapt its gender by changing its gendered voice to match the gender of the child. By analyzing the free play of children, the results obtained confirm the hypothesis of gender segregation within child-robot interaction. These findings are important and ought to be considered when designing robotic applications for children in order to increase robot's perceived likeability, acceptance and engagement.

Given the growth in the usage of Web Applications, the usability of these applications has become a key success factor. There are several technologies to evaluate and improve this quality factor. However, the usability inspections results still depend on the inspector's experience. We have proposed a Web usability inspection approach, called WE-QT (Web Evaluation -- Question Technique), a question based technique that aims to reduce the difficulties of inspectors with little knowledge of usability. We are following an empirical methodology to support its development and improvement. This paper presents two experimental studies conducted until this point of the research: a feasibility and an observational study. We discuss the qualitative and quantitative results of both studies and their impact on improving the WE-QT. With this paper we also aim to spread the knowledge about experimental studies to evaluate and evolve a new software engineering technology. [ABSTRACT FROM PUBLISHER]

A common data model for clinical NGS panel data that is used in a distributed research network to achieve large scale to make evidence for improving patient care should be developed. This study developed OMOP-CDM extension for NGS panel data and confirmed the feasibility of the model by finding the differences between a database generated by research-purpose and clinical practice. We believe this data model can be used in distributed research model and will facilitate the usage of the clinical NGS data in patient care. [ABSTRACT FROM AUTHOR]

Large healthcare datasets of Electronic Health Record data became indispensable in clinical research. Data quality in such datasets recently became a focus of many distributed research networks. Despite the fact that data quality is specific to a given research question, many existing data quality platform prove that general data quality assessment on dataset level (given a spectrum of research questions) is possible and highly requested by researchers. We present comparison of 12 datasets and extension of Achilles Heel data quality software tool with new rules and data characterization measures. [ABSTRACT FROM AUTHOR]

We expanded and constructed a Common Data Model (CDM) based on hospital EHR to enable analysis and comparison of Adverse Drug Reactions(ADRs) integrated with external organizations with different data structures. This is significant in that it is possible to conduct joint research, analysis, and comparisons among institutions with the same type of CDM constructed, and provide the basis for conducting the same research simultaneously on various data sources.

The Rwandan Ministry of Health supports a countrywide installation of the Open Medical Record System (OpenMRS) to improve clinical recordkeeping and patient care. However, electronic medical records also can be a valuable source of data for observational and experimental studies. We describe the challenges and lessons learned when reusing OpenMRS data in Rwanda for global HIV epidemiology research. [ABSTRACT FROM AUTHOR]

The OHDSI Common Data Model (CDM) is a deep information model, in which its vocabulary component plays a critical role in enabling consistent coding and query of clinical data. The objective of the study is to create methods and tools to expose the OHDSI vocabularies and mappings as the vocabulary mapping services using two HL7 FHIR core terminology resources ConceptMap and ValueSet. We discuss the benefits and challenges in building the FHIR-based terminology services. [ABSTRACT FROM AUTHOR]
