Objectives: The clinical document forms, a format for collecting clinical data, is the most fundamental object of standardization. Doctors must have a mutual understanding of the clinical chart. Methods: Clinical document forms were developed by investigating existing conditions in hospitals and conducting demand surveys, doing literature research, and seeking expert advice for the improvement of version 1.0. In addition, an organization of a network of 19 Oriental medical doctors and nurses, 190 patients, and users of collected and assessed data was formed to come up with version 2.0. Results: The overall format was divided into different portions that the patient, nurse, and doctor must fill out, respectively. The patient's section consists of demographic data, lifestyle details, history, and symptoms. The data to be supplied by the nurse include the patient's vital signs and anthropometric parameters. As for the doctors, they are to supply data regarding the patient's palpitation, the detailed symptoms of the patient's head, ophthalmological and otorhinolaryngological symptoms (mouth), respiration, circulatory organ and chest conditions, digestive-organ conditions (thirst), neuropsychiatric conditions, reproductive system, musculoskeletal system, skin (depilation), etc. Conclusions: Common clinical chart development is the prior question to Traditional Korean Medicine standardization. A web-based clinical document format should be developed to support diagnosis and treatment, and furthermore EMR (electronic medical record system) and EHR (electronic health record) developed. Clinical information could be shared through a network of medical institutions and be useful Traditional Korean Medicine for evidence-based medicine.

Purpose: To provide clear estimates of the adoption and use of electronic nursing records (ENRs) with standard terminology in Korea and identification of the scope and use as well as perceived or potential benefits of ENRs. Methods: A survey was done of 733 hospitals at three levels: tertiary advanced hospitals, general hospitals, and community hospitals. After performing a literature review a modified version of an existing survey tool was used for 2 months in 2012. The collected information related to EHR functionality and coverage of nursing documentation and nursing process, application of standard terminology, and perceived satisfaction and benefits of ENRs. Results: The response rate was 39.4% (289/733), and 202 hospitals (70.1%, 95% CI64.8~75.5%) of the respondents had ENR systems (82.5% of tertiary hospitals, 66.7% of general hospitals, and 70.1% of community hospitals). Out of these hospitals less than 10% had ENRs fully covering nursing documentation. The adoption rate of standard terminology was 55%, and hospital satisfaction with ENRs was 70%. But personalized care was identified as needing improvement in ENRs. Conclusion: The ENR adoption rate was high but there are many potential opportunities for improving ENR systems in terms of the data standardization and personalized care.

Purpose: The purpose of this study was to develop predictive models for pressure ulcer incidence using electronic health record (EHR) data and to compare their predictive validity performance indicators with that of the Braden Scale used in the study hospital. Methods: A retrospective case-control study was conducted in a tertiary teaching hospital in Korea. Data of 202 pressure ulcer patients and 14,705 non-pressure ulcer patients admitted between January 2015 and May 2016 were extracted from the EHRs. Three predictive models for pressure ulcer incidence were developed using logistic regression, Cox proportional hazards regression, and decision tree modeling. The predictive validity performance indicators of the three models were compared with those of the Braden Scale. Results: The logistic regression model was most efficient with a high area under the receiver operating characteristics curve (AUC) estimate of 0.97, followed by the decision tree model (AUC 0.95), Cox proportional hazards regression model (AUC 0.95), and the Braden Scale (AUC 0.82). Decreased mobility was the most significant factor in the logistic regression and Cox proportional hazards models, and the endotracheal tube was the most important factor in the decision tree model. Conclusion: Predictive validity performance indicators of the Braden Scale were lower than those of the logistic regression, Cox proportional hazards regression, and decision tree models. The models developed in this study can be used to develop a clinical decision support system that automatically assesses risk for pressure ulcers to aid nurses.

Objectives: The objective of this study was to investigate the relationship between the level of Electronic Medical Record (EMR) system adoption and healthcare information technology (IT) infrastructure. Methods: Both survey and various healthcare administrative datasets in Korea were used. The survey was conducted during the period from June 13 to September 25, 2017. The chief information officers of hospitals were respondents. Among them, 257 general hospitals and 273 small hospitals were analyzed. A logistic regression analysis was conducted using the SAS program. Results: The odds of having full EMR systems in general hospitals statistically significantly increased as the number of IT department staff members increased (odds ratio [OR] = 1.058, confidence interval [CI], 1.003-1.115; p = 0.038). The odds of having full EMR systems was significantly higher for small hospitals that had an IT department than those of small hospitals with no IT department (OR = 1.325; CI, 1.150-1.525; p < 0.001). Full EMR system adoption had a positive relationship with IT infrastructure in both general hospitals and small hospitals, which was statistically significant in small hospitals. The odds of having full EMR systems for small hospitals increased as IT infrastructure increased after controlling the covariates (OR = 1.527; CI, 1.317-4.135; p = 0.004). Conclusions: This study verified that full EMR adoption was closely associated with IT infrastructure, such as organizational structure, human resources, and various IT subsystems. This finding suggests that political support related to these areas is indeed necessary for the fast dispersion of EMR systems into the healthcare industry.

This study is an investigation into the factors affecting patient dissatisfaction among Saudi hospitals. The selected factors considered for analysis are security of information sharing, operational practices, disruptive technologies, and the ease of use of EHR patient information management systems. From the literature review section, it was clear that hardly any other studies have embraced these concepts in one as was intended by this study. The theories that the study heavily draws from are the service dominant logic and the feature integration theory. The study surveyed 350 respondents from three large major hospitals in three different metropolitan cities in the Kingdom of Saudi Arabia. This sample came from members of the three hospitals that were willing to participate in the study. The number 350 represents those that successfully completed the online questionnaire or the limited physical questionnaires in time. The study employed the structural equation modelling technique to analyze the associations. Findings suggested that security of information sharing had a significant direct effect on patient satisfaction. Operational practice positively mediated the effect of security of information sharing on patient dissatisfaction. However, ease of use failed to significant impact this association. The study concluded that to improve patient satisfaction, Saudi hospitals must work on their systems to reinforce them against the active threats on the privacy of patients' data by leveraging disruptive technology. They should also improve their operational practices by embracing quality management techniques relevant to the healthcare sector.

PURPOSE: Computerization using ICF as a protocol can enhance the assessment, communication, and decision-making of various disciplines and cultures, individual functions, disabilities and health to promote communication and understanding among various professionals, organizations, and countries. The empirical foundation for these propositions was provided by delineating of six distinct computerization components. METHODS: This study analyzed 14 papers that combined the medical field and information technology to activate the ICF through computerization. From each of these papers, distinctive advantages were extracted to propose six computerization elements. The validity of these computerization elements was examined. These papers encompass various computerization elements, among which core elements were identified. In particular, six common core elements were extracted from these papers and assumed to be strategic computerization components for ICF activation. A heuristic methodology was employed to validate these components, representing IT technology maturity using four determining indices, which were then presented graphically for validation attempts. RESULTS: Four quantified indices were defined: reliability, cost-effectiveness, support and updates, and collaboration. Using these indices, this study identified elements that leverage existing IT technologies and require new development. The possibility of increasing utility was identified by applying computerization to ICF. CONCLUSION: This study examined the strategic elements of utilizing ICF by computerizing it using a protocol concept and discussed its potential for utilization. The potential to enhance the value of information in social, physical, and cultural contexts was presented by integrating various domains and data within the ICF framework.
