Abstract Objective Improving the patient experience has become an essential component of any healthcare system’s performance metrics portfolio. In this study, we developed a machine learning model to predict a patient’s response to the Hospital Consumer Assessment of Healthcare Providers and Systems survey’s “Doctor Communications” domain questions while simultaneously identifying most impactful providers in a network. Materials and Methods This is an observational study of patients admitted to a single tertiary care hospital between 2016 and 2020. Using machine learning algorithms, electronic health record data were used to predict patient responses to Hospital Consumer Assessment of Healthcare Providers and Systems survey questions in the doctor domain, and patients who are at risk for responding negatively were identified. Model performance was assessed by area under receiver-operating characteristic curve. Social network analysis metrics were also used to identify providers most impactful to patient experience. Results Using a random forest algorithm, patients’ responses to the following 3 questions were predicted: “During this hospital stay how often did doctors. 1) treat you with courtesy and respect? 2) explain things in a way that you could understand? 3) listen carefully to you?” with areas under the receiver-operating characteristic curve of 0.876, 0.819, and 0.819, respectively. Social network analysis found that doctors with higher centrality appear to have an outsized influence on patient experience, as measured by rank in the random forest model in the doctor domain. Conclusions A machine learning algorithm identified patients at risk of a negative experience. Furthermore, a doctor social network framework provides metrics for identifying those providers that are most influential on the patient experience.

Objectives. The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) is a well-established and internationally recognized scale for measuring patient experience with hospital inpatient care. This study aimed to develop a Japanese version of the HCAHPS and to examine its structural validity, criterion-related validity, and internal consistency reliability. Design. Multicenter cross-sectional study. Setting. A total of 48 hospitals in Japan. Participants. Patients aged ≥ 16 years who were discharged from the participating hospitals. Results. We translated the HCAHPS into Japanese according to the guidelines. Psychometric properties were examined using data from 6,522 patients. A confirmatory factor analysis showed excellent goodness of fit of the same factor structure as that of the original HCAHPS, with the following composites: communication with nurses, communication with doctors, responsiveness of hospital staff, hospital environment, communication about medicines, and discharge information. All hospital-level Pearson correlation coefficients between the Japanese HCAHPS composites and overall hospital rating exceeded the criteria. Results of inter-item correlations indicated adequate internal consistency reliability. Conclusions. We developed the Japanese HCAHPS, and evaluated its structural validity, criterion-related validity, and internal consistency reliability. This scale could be used for quality improvement based on the assessment of patient experience with hospital care and for health services research in Japan.

Cybercrime is a growing threat for firms and customers that emerged with the digitization of business. However, research shows that even though people claim that they are concerned about their privacy online, they do not act correspondingly. This study investigates how prevalent security issues are during a cyber attack among Twitter users. The case under examination is the security breach at the US ticket sales company, Ticketfly, that compromised the information of 26 million users. Tweets related to cybersecurity are detected through the application of automated text classification based on supervised machine learning with support vector machines. Subsequently, the users that wrote security-related tweets are grouped into communities through a social network analysis. The results of this multi-method study show that users concerned about security issues are mostly part of expert communities with already superior knowledge about cybersecurity.

Many analytical tasks, such as social network analysis, depend on comparing graphs. Existing methods are slow, or can be difficult to understand. To address these challenges, this paper proposes gragnostics, a set of 10 fast, layperson-understandable graph-level features. Each can be computed in linear time. To evaluate the ability of these features to discriminate different topologies and types of graphs, this paper compares a machine learning classifier using gragnostics to alternative classifiers, and the evaluation finds that the gragnostics classifier achieves higher performance. To evaluate gragnostics' utility in interactive visualization tools, this paper presents Chiron, a graph visualization tool that enables users to explore the subgraphs of a larger graph. Example usage scenarios of Chiron demonstrate that using gragnostics in a rank-by-feature framework can be effective for finding interesting subgraphs.

Albeit the importance of patient experience, most questionnaires are only available in English. To understand the hospital experience of Filipino patients, a psychometrically sound instrument in Filipino is warranted. This study culturally adapted and validated the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) into Filipino. A 5-step cross-cultural validation process was conducted. Forward translation, back-translation, and panel reconciliation involved 7 language experts. Pretesting included content validation and pretesting of the Filipino HCAHPS, while field testing involved 64 purposively selected hospitalized patients who completed a 4-part survey from July to December 2018. Content, linguistic, and conceptual equivalence and internal consistency were statistically appraised. Content validation yielded a scale content validity index/average of 1.00. Comparative analysis and Bland-Altman plots indicated good linguistic equivalence. All correlation coefficients were ≥.30, denoting good conceptual equivalence. Cronbach’s α for both versions of HCAHPS were ≥0.80, suggestive of good internal consistency. The Filipino HCAHPS is a psychometrically sound and culturally appropriate tool to measure patient experience among Filipinos. This understanding can be utilized for quality improvements on both practice and policy levels.

MicroRNAs constitute an important class of noncoding, single-stranded, ~22 nucleotide long RNA molecules encoded by endogenous genes. They play an important role in regulating gene transcription and the regulation of normal development. MicroRNAs can be associated with disease; however, only a few microRNA-disease associations have been confirmed by traditional experimental approaches. We introduce two methods to predict microRNA-disease association. The first method, KATZ, focuses on integrating the social network analysis method with machine learning and is based on networks derived from known microRNA-disease associations, disease-disease associations, and microRNA-microRNA associations. The other method, CATAPULT, is a supervised machine learning method. We applied the two methods to 242 known microRNA-disease associations and evaluated their performance using leave-one-out cross-validation and 3-fold cross-validation. Experiments proved that our methods outperformed the state-of-the-art methods.
