Diffusion of Electronic Medical Record Based Public Hospital Information Systems / 대한의료정보학회지

OBJECTIVES: This study was conducted to evaluate the adoption behavior of a newly developed Electronic Medical Record (EMR)-based information system (IS) at three public hospitals in Korea with a focus on doctors and nurses. METHODS: User satisfaction scores from four performance layers were analyzed before and two times after the newly develop system was introduced to evaluate the adoption process of the IS with Rogers' diffusion theory. RESULTS: The 'intention to use' scores, the most important indicator for determining whether or not to adopt the IS in Rogers' confirmation stage for doctors, were very high in the third survey (4.21). In addition, the scores for 'reduced medication errors', which is the key indicator for evaluating the success of the IS, increased in the third survey for both doctors and nurses. The factors influencing 'intention to use' with a high odds ratio (>1.5) were the 'frequency of attendance of user training sessions', 'mandatory use of system', 'reduced medication errors', and 'reduced medical record documentation time' for both doctors and nurses. CONCLUSIONS: These findings show that the new EMR-based IS was well accepted by doctors. Both doctors and nurses also positively considered the effects of the new IS on their clinical environments.

Performance Evaluation of Public Hospital Information Systems by the Information System Success Model / 대한의료정보학회지

OBJECTIVES: This study was to evaluate the performance of the newly developed information system (IS) implemented on July 1, 2014 at three public hospitals in Korea. METHODS: User satisfaction scores of twelve key performance indicators of six IS success factors based on the DeLone and McLean IS Success Model were utilized to evaluate IS performance before and after the newly developed system was introduced. RESULTS: All scores increased after system introduction except for the completeness of medical records and impact on the clinical environment. The relationships among six IS factors were also analyzed to identify the important factors influencing three IS success factors (Intention to Use, User Satisfaction, and Net Benefits). All relationships were significant except for the relationships among Service Quality, Intention to Use, and Net Benefits. CONCLUSIONS: The results suggest that hospitals should not only focus on systems and information quality; rather, they should also continuously improve service quality to improve user satisfaction and eventually reach full the potential of IS performance.

The Association of Helicobacter pylori Infection and Anemia in Patients with Gastritis

BACKGROUND: Helicobacter pylori has been known to be not only associated with gastrointestinal diseases but also to be reported in several cases of increased incidence of anemia. The anemia associated with H. pylori infection was reported though the population studies and case reports. But in Korea, there have been not enough studies especially in adults group, so we investigated to find out if H. pylori infection is associated with anemia in adults with gastritis. METHODS: Subjects were 382 men older than 40 years and 158 postmenopausal women, who had visited a general hospital for physical examination from May 2001 to October 2001 and diagnosed as only gastritis. Data were analysed for the effects of H. pylori infection on anemia using logistic regression test. RESULTS: In men, Pearson correlation coefficients between age and hemoglobin, and hematocrit were -0.163, -0.136, respectively (P0.05) respectively. Logistic regression analysis adjusted for age showed the lower odds ratio for anemia in both men and women without H. pylori than in those with H. pylori, but it was not significant. CONCLUSION: H. pylori infection seems not to affect hemaglobin and hematocrit in the middled-aged men and the postmenopausal women with gastritis. Further investigations will be necessary for various individuals including infants and premenopausal women who may have high incidence for anemia.
