Cerebral Venous Infarction Due to Brachial Artery-Jugular Vein Jump Graft in a Hemodialysis Patient

Hemodialysis patients rarely experience neurologic symptoms related to their vascular accesses. However, occlusion of venous drainage induces extreme venous hypertension and in rare cases cause intracranial venous congestion. We report a patient with cerebral venous infarction resulting from reflux flow into the cranium induced by an arteriovenous jump graft to the internal jugular vein. Clinicians should take into account the possibility of neurologic deficit related to intracranial venous hypertension in hemodialysis patients.

The Risk of Microalbuminuria by Obesity Phenotypes according to Metabolic Health and Obesity: The Korean National Health and Nutrition Examination Survey 2011–2014 / 가정의학회지

BACKGROUND: The present study aimed at identifying the difference in the risk of microalbuminuria among individuals with various obesity phenotypes in terms of metabolic health and obesity. METHODS: This cross-sectional study included 15,268 individuals and used data from the National Health and Nutrition Survey conducted from 2011 to 2014. Obesity was defined as body mass index ≥25 kg/m2. Metabolically unhealthy was defined as meeting two or more of the following criteria: systolic and diastolic blood pressure ≥130/85 mm Hg or current use of hypertensive drugs; triglyceride level ≥150 mg/dL; high-density lipoprotein level < 40/50 mg/dL (in both men and women); and fasting blood glucose level ≥100 mg/dL or current use of oral antidiabetic medications. The participants were further classified into four subgroups: metabolically healthy non-obese (MHNO), metabolically healthy obese (MHO), metabolically unhealthy non-obese (MUNO), and metabolically unhealthy obese (MUO). RESULTS: A significant difference was observed in the microalbuminuria ratio among the four groups. The MHNO group was considered as the reference group, and the MHO, MUNO, and MUO groups were at an increased risk for microalbuminuria by 1.42 fold (95% confidence interval [95% CI], 1.03–1.96), 2.02 fold (95% CI, 1.61–2.53), and 3.40 fold (95% CI, 2.70–4.26), respectively, after adjusting confounding factors. CONCLUSION: The MUNO group had a higher risk of developing microalbuminuria than the MHNO group. Thus, based on this result, differences were observed in the risk of developing microalbuminuria among individuals with various obesity subtypes.

Invasive Sphenoid Sinus Aspergillosis Presenting Hemicrania Continua-Like Headache

Hemicrania continua (HC) is an indomethacin-responsive primary headache. Owing to continuous unilateral headache and clinical rarity, a great attention should be paid during the diagnosis of HC to exclude secondary causes of headache. Various pathologies have been described for HC-like headache. We describe a 64-year old man with invasive sphenoid sinus aspergillosis who presented continuous unilateral headache, trigeminal autonomic symptoms and response to oral indomethacin 225 mg/day. He was treated with intranasal ethmoidectomy and antifungal agent, and his headache has greatly improved.

Statistical Analysis System of Spontaneous Adverse Drug Reaction Reports

BACKGROUND: Spontaneous adverse drug reaction (ADR) reporting data has been used for safety of post-market drug surveillance. A system has been required that is able to detect signals associated with drugs by analyzing the collected ADR data. METHODS: We developed the web-based automated analysis system (ADR-detector). We used the data which reported ADR spontaneously between March 2009 and December 2010 to Korean Food and Drug Administration. We used 3 statistical indicators for evaluating ADR signals: proportional reporting ratio (PRR), reporting odds ratio (ROR), and information component (IC). The ADR reports which were detected as significant signals based on the indicators have been reviewed. RESULTS: Among 153,774 reports, 9,955 cases were related to 4 analgesics which were most frequently reported analgesic drugs during the study period. The numbers of ADR reports associated with each drug are as follow: 5,623 reports in tramadol (56.5 %), 1,720 reports in fentanyl (17.3 %), 1,463 reports in tramadol-combination (14.7 %), and 1,149 reports in ketorolac (11.5 %). Top 5 ADR were nausea (3,351 reports - 33.7 %), vomiting (1,755 reports - 17.6 %), dizziness (1,130 - 11.4 %), rash (412 reports - 4.1 %), and pruritus (354 reports - 3.6 %). 6,674 ADR reports were significant based on PRR and ROR, and 336 reports were significant based on IC. CONCLUSION: By using the automated analysis system, not only statisticians but also general researchers are able to analyze ADR signals in real-time. Also ADR-detector would provide rapid review and cross-check of ADR.

Successful use of customer relationship management system in hospital healthcare centers

Customer relationship management (CRM) is a valuable method for establishing long-term customer relationships across different business areas. CRM system stores and analyzes a vast amount of customer information and provides alternatives to meet customer expectations using data warehouse and on-line analysis processing technology. Intensified competitiveness in the healthcare industry has increased the number of healthcare centers and propelled the introduction of CRM systems to meet diverse customer satisfaction. Leading the adoption of information technology in the healthcare businesses has enabled the use of CRM technology to develop close patient-provider relationship. Especially, healthcare centers are using CRM system to provide better healthcare services as well as customer management services. This study aims to explore the current status and influential factors that will stimulate and drive the successful use of CRM system in healthcare centers. For this purpose, a survey has been conducted for CRM system users in 13 healthcare centers to investigate the current status of CRM system and the influential factors for successful use. The evaluation criteria include four categories; system quality, information quality, service quality and perceived usefulness. These criteria have been developed based on previous researches, especially DeLone & McLean information system success model. In addition, the system output is evaluated by user satisfaction, personal performance and organizational performance. The study showed that users evaluated information quality and service quality positively and to be higher than other factors in terms of influence. And the user evaluation proved that CRM system provides increased user satisfaction, organizational performance, and especially, individual performance. This is clear evidence that CRM system will improve organizational efficiency and effectiveness, which in turn, can provide competitive advantage for the healthcare centers.

Wireless Clinical Trial of Data Capture using a Personal Digital Assistant / 대한의료정보학회지

OBJECTIVE: Personal Digital Assistants (PDAs) have the potential to improve clinical trial data collection; however, most current PDA-based clinical data collection systems typically collect and store data in the offline mode, and then transfer the data to an operational database. The purpose of this study was to explore the usefulness of a wireless clinical data collection system for an irritable bowel syndrome trial compared with the traditional paper based data collection. METHODS: We have developed a PDA-based data capture system for clinical trials, and tested it in a double-blind trial. Sixty four patients with irritable bowel syndrome were randomly selected and divided into a control group that used the standard paper report forms (CRF) and an intervention group that used the electronic report forms (e-CRF), daily for five weeks. There were 630 data sets consisting of six questions each, and thus 3,570 data points total were collected. RESULTS: The response rate of the control group was significantly higher than that of the intervention group. However, the completeness of the response in the intervention group was higher and the number of input errors per person for the PDA group was lower than in the paper group. CONCLUSION: A PDA based electronic diary improved the response rate and decreased input errors in an IBS trial. We conclude that mobile devices can be very useful, especially when the proposed design and connectivity aspects have been taken into account.

Arden Syntax as a standard expression language for medical knowledge / 대한의료정보학회지

The Arden Syntax is a language for expressing computable medical decisions. It was developed and published under the direction of Health Level Seven, Inc (HL7), and is a standard of the American National Standards Institute (ANSI). It is used to construct executable Medical Logic Modules (MLMs) that represent individual clinical decisions. The authors introduced brief explanation of the Arden Syntaxand gave an example to help readers understand it with easy. Although Arden Syntax is the HL7 standard, there are problems related to the adoption of Arden Syntax as the standard tool for describing medical logic: the curly-braces problem, and the compiler problem. GELLO as well as virtual Medical Record based on the HL7 Reference Information Model (RIM) may provide solutions to the former problem. The latter problem would be resolved by introducing XML based expression of Arden Syntax, the ArdenML: the next generation of Arden Syntax. Unfortunately, Korean hospital information systems are not yet ready to adopt clinical decision support system including Arden Syntax. However, when Arden Syntax version 3.0 (ArdenML) with Korean rule-base engines is introduced into the hospital information system, it would be easier to build up clinical decision support system in Korea.

Prevalence and Risk Factors Associated with Suicide Ideation and Attempts in Korean College Students

OBJECTIVE: Suicide is a leading cause of death in college age students. Identification of the associated risk factors has important implications for how to prevent and respond to this population; however, few studies have been performed on this topic in this age group. The purpose of this study was to evaluate the prevalence and risk factors associated with suicide ideation and attempts in college students. METHODS: Three hundred sixty-eight college students participated in this cross-sectional observational study. The recent (over two weeks) suicide ideation and lifetime suicide attempts were defined according to Moscicki's suicide behavior index. Sociodemographic variables were assessed and psychopathology measured using the Beck Depression Inventory, the Bipolar Spectrum Diagnostic Scale and the Alcohol Use Disorders Identification Test. A hierarchical multiple logistic regression analysis was used to identify the significant risk factors related to suicide ideation and attempts. RESULTS: The two-week prevalence of suicidal ideation was 9.8%, and the lifetime prevalence of suicide attempts was 3.3%. The univariate analysis showed that students who had more severe depression (p<0.001), a higher probability for bipolar disorder (p<0.001) and decrement of academic achievement (p<0.005) were more likely to have suicide ideation. Those with factors such as severe depression (p<0.05), a higher probability of bipolar disorder (p<0.001), a low socioeconomic status (p<0.001), who lived alone (p<0.01), and were female (p<0.05) had a higher risk for suicide attempts. The most important predictors of suicide ideation, by the logistic regression analysis, were depression, probability for bipolar disorder and academic achievement, and the risks identified for suicide attempts were socioeconomic status and probability of bipolar disorder. CONCLUSION: Suicide ideation and attempts were common in college students. The results of this study suggest that early identification and management of mood disorders and other sociodemographic risk factors may have implications for intervention and prevention.

Comparison of the Perception on Health Information Privacy Protection for Electronic Health Record among Patients, Healthcare Providers and Administration Groups / 대한의료정보학회지

OBJECTIVE: As the accelerated development and use of Electronic Health Record have grown exponentially, the possible disclosure of patient healthcare information is increased. The purpose of this study is to examine the perception gap on disclosure of EHR information among the patient/guardian group, healthcare provider group, and administration group. METHODS: A questionnaire survey from a hospital located in Incheon City of Korea was conducted and over 200 responses were collected. Outcome measures include healthcare information protection, disclosure of unidentifiable information, possible losses from the disclosure of healthcare information, and the ownership of healthcare information. RESULTS: Regarding healthcare information protection, three groups have a general consensus over some issues. In contrast, the healthcare providers and the administration group have a higher consideration regarding possible losses resulting from the disclosure of healthcare information than the patient group. In addition, the healthcare provider group considered the ownership of healthcare information to belong to the hospital in contrast with the patients' view that the ownership and disclosure rights belong to the patient. CONCLUSION: These findings indicate that the high level of interest and concern that our results revealed, suggests that more attention should be directed toward designing and developing policy, organization and legislative systems.

Key Aspects of Using Web-based Diabetes Telemedicine Systems in Multiple Clinical Settings / 대한의료정보학회지

OBJECTIVE: Even though abundant studies and models have tried to explain and predict the adoption and use of new information systems, the research on the adoption of Diabetes Management Systems in multiple clinical settings is relatively scarce. This paper addresses this issue by outlining Georgetown University's experience with implementing its MyCareTeam diabetes telemedicine application, which is a web.based, interactive diabetes management application. METHODS: Case study is used to explore the influencial factors on web.based diabetes telemedicine systems in multiclinical setting. The experience of the Georgetown University deploying MyCareTeam system in six different geographical areas was analyzed by secondary literature review and interviews. RESULTS: This study finds several problems and possible resolutions to expand the telemedicine systems of single institution into the multiple clinical settings. The application systems must be able to transfer data from diverse medical devices and integrate with web.based diabetes management application. Therefore, the system needs to support diverse data transfer type, diverse cable, and different network environment. In addition, there is a need for more dedicated technical and operational support, to prevent frequent turnover among the overburdened nurses who currently interact remotely with telemedicine patients. CONCLUSIONS: To apply currently developed telemedicine technology into the real clinical settings, the proposed technical as well as organizational infrastructure should be established. The findings of this study will be guideline for multi.center diabetes management system in Korea.

A Study on Facilitators and Inhibitors to the Introduction of Outsourcing in the Hospital Information Systems in Korea / 예방의학회지

OBJECTIVES: This study was conducted to investigate the current status of outsourcing in Korean hospital information systems and the factors influencing its introduction. METHODS: The authors surveyed 136 hospitals located in Seoul and its surrounding vicinities from June 7 to June 23, 2006. The facilitators and inhibitors to outsourcing in hospital information systems were derived from literature and expert reviews. Multiple logistic regression analysis was applied to identify the major influencing factors on outsourcing in hospital information systems. RESULTS: Eighty-six (63.2%) of the 136 hospitals surveyed, which were mainly tertiary hospitals, responded to using outsourcing for their hospital information systems. "Hardware and software maintenance and support," "application development," and "management of service and staff" were the major areas of outsourcing. Outsourcing had been employed for 4~7 years by 45.5% of the hospitals and the proportion of the budget used for outsourcing was less than 20%. A need for an extension in outsourcing was agreed on by 76.5% of the hospitals. The multiple logistic regression analysis showed that both consumer satisfaction and security risk have an influence on hospital information system outsourcing. CONCLUSIONS: Outsourcing in hospital information systems is expected to increase just as in other industries. One primary facilitator to outsourcing in other industries is consumer satisfaction. We found that this was also a facilitator to outsourcing in hospital information systems. Security risk, which is usually considered an inhibitor to information technology outsourcing, was proven to be an inhibitor here as well. The results of this study may help hospital information systems establish a strategy and management plan for outsourcing.

Information Sources and Knowledge on Infant Vaccination according to Online Communities / 예방의학회지

OBJECTIVES: To explore the information sources and knowledge on infant vaccinations of pro-vaccination community members and anti- accination community members on the internet. METHODS: An online survey of 245 parents from three pro-vaccination communities and 92 parents from one antivaccination community was conducted from June 7 to June 23, 2006. RESULTS: Parents from pro-vaccination communities usually gained the information regarding vaccination efficacy and risk mainly from healthcare providers (49.8%) and mass media (47.7%). Pro-vaccination community members considered healthcare providers as the most credible sources of information on vaccination, whereas the anti-vaccination community members usually gained their information regarding vaccine efficiency and risk from Internet child-care cafes and online vaccination communities. Parents of the anti-vaccination community considered the internet as the most credible information source (77.6% for efficacy, 94.8% for risk). In addition, the major reason why anti-vaccination community members didn't vaccinate and, will not vaccinate, was concern about possible side effects of the vaccine. The knowledge level on infant vaccination, education and economic status was higher in the anti-vaccination community. CONCLUSIONS: On-line communities concerned with vaccination are getting popular. The influence of antivaccination parents on the Internet is expected to be high. The government and healthcare providers need to increase their efforts to improve the credibility of information about vaccination. Our findings suggest that online communication regarding vaccinations needs to be considered as a means to increase vaccination rates.
