ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
This study aimed to determine prevalence, differentiate underlying causes, and identify the benign group in subjects with asymptomatic T-wave inversion (TWI). We retrospectively read 12-lead electrocardiograms from 3,929 consecutive asymptomatic men in the air force (3,929 participants, mean age 39.3 ± 8.7 years) who underwent medical screening at the Aerospace Medical Center, Korea, from September 2010 to August 2012. TWIs other than in right precordial leads (V1 and V2) were present in 23 men (0.6%). All subjects with persistent TWI for 1 year (n = 18) underwent additional study, with the exception of 1 patient who refused further evaluation. Of 17 subjects with investigated persistent TWI, 8 (47.1%) had an apically displaced papillary muscle, 5 (29.4%) exhibited idiopathic TWI, 3 (17.6%) had apical hypertrophic cardiomyopathy, and 1 (5.9%) had Maron type 2 hypertrophic cardiomyopathy with dynamic left ventricular outflow obstruction. The depth of TWI was significantly shallow in the benign group (idiopathic TWI, 1.6 ± 0.5 mm) compared with potentially nonbenign group (the others; 5.5 ± 3.3 mm, p = 0.021). Lateral lead TWI was significantly correlated with potentially nonbenign group (46% vs 0%, p = 0.049). In conclusion, asymptomatic TWI is not rare (0.6%), even in a healthy population such as Korean Air Force society, and at least 29.4% of subjects with TWI are considered to belong to the benign group that does not require aggressive evaluation and criteria of TWI ≤2 mm other than lateral leads without co-morbidity could help to distinguish the benign group from the potentially nonbenign group.
