PURPOSE: As our society ages, a disease like benign prostatic hyperplasia (BPH) are increasing and needs consequent management. Recently, through the expansion of the communication infrastructure and terminals, a network services can be provided. However, the concern about distant medical management is increasing. We introduce here the Personal BPH Control Program (PBCP) and its application to clinical patients. MATERIALS AND METHODS: We have asked BPH patients to input the variable elements on the digital survey through the Personal Digital Assistant (PDA) once a week. We used the International Prostate Symptom Score (IPSS) and the average flow rate as the variable elements. We have used an algorithm to determine the patients condition. With this, we have developed a program that helps patients to adjust their visits to the hospital. RESULTS: According to the input elements, we have determined that the patients' condition was good (visit the hospital every 3 months) when the IPSS decreased, compared with the baseline and when the average flow rate was up above 2ml/sec. The patients' condition was a warning (visit the hospital every 2 months) when the IPSS was increased to below 3 and the average flow rate was down below +/- 2ml/sec, and the patients' condition was urgent when the IPSS increased to above 4 and the average flow rate was down above 3ml/sec. CONCLUSIONS: We expect that the PBCP has great socioeconomic utility when applying it to patients. A portable personal apparatus for measuring the flow rate is now being developed. When sufficient examples of applying the symptom algorithm have accumulated, we are going to report afterward the prospects of using the PBCP in the future.

BACKGROUND: It is known that there are various factors associated with children's screen overuse. The aim of this study was to examine the effect of maternal depression on 2–5-year-old children's overuse of various household screen devices. METHODS: Participants were from the Internet-Cohort for Understanding of internet addiction Risk factors/Rescue in Early livelihood (I-CURE) study, an observational prospective cohort study in Korea. Screen time for six types of screen devices (smartphone, television, computer, tablet, video gaming console, and portable gaming console) were assessed by parental questionnaire. Maternal depression was measured by the Korean version of the Beck Depression Inventory II. Logistic regression models were run to determine the association between maternal depression and children's screen overuse. RESULTS: Maternal depression was associated with children's television overuse after adjusting for other factors (odds ratio, 1.954; P = 0.034). Contrary to expectation, the relationship between maternal depression and screen time was not present on other devices such as smartphones, computers and tablets. CONCLUSION: Maternal depression is related with 2–5-year-old children's television overuse. Interventions in maternal depressive symptoms and the associated changes in parent-child relationship can be useful for preventing children's television overuse.

PURPOSE: The aim of this study was to determine whether two methods of documentation, print and electronic forms, for the assessment of patient-reported outcomes (PRO) in complete denture wearers provide comparable results. The study also quantified the time needed for filling the forms by each method. MATERIALS AND METHODS: Thirty participants enrolled in a university clinic answered two forms (a questionnaire for denture satisfaction and OHIP-EDENT). They provided answers with two application methods in a random order, with a one-month interval between them: (1) electronic forms on a tablet computer; and (2) print forms. The methods were compared in terms of mean results, correlation/agreement, internal consistency, and spent time. RESULTS: Mean results for both methods were similar for each denture satisfaction item (100-mm VAS) and OHIP-EDENT summary score. Both questionnaires presented good internal consistency regardless of the application method (Cronbach's α=0.86 or higher). Correlation and agreement between the methods regarding specific items was at least moderate for the majority of cases. Mean time for the electronic and print forms were 9.2 and 8.5 minutes, respectively (paired t test, P=.06, non-significant). CONCLUSION: The electronic method is comparable to print forms for the assessment of important PRO of prosthetic treatment for edentulism, considering the results and time needed. Findings suggest the viability of replacing print forms with a tablet for applying the tested inventories in clinical trials.

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.

7.Development and Application of Direct Data Capture for Monitoring Medication Compliance in Clinical Trials.
Healthcare Informatics Research 2017;23(4):249-254
OBJECTIVES: The monitoring of medication compliance in clinical trials is important but labor intensive. To check medication compliance in clinical trials, a system was developed, and its technical feasibility evaluated. METHODS: The system consisted of three parts: a management part (clinical trial center database and a developed program), clinical trial investigator part (monitoring), and clinical trial participant part (personal digital assistant [PDA] with a barcode scanner). The system was tested with 20 participants for 2 weeks, and compliance was evaluated. RESULTS: This study developed a medication compliance monitoring system that used a PDA with a barcode scanner, which sent reminder/warning messages, logged medication barcode data, and provided compliance information to investigators. Registered participants received short message service (SMS) reminder/warning messages on their PDA and sent barcode data at the dosing time. The age range of the participants was 29 to 73 years. Five participants were <50 years old and 8 were ≥65 years old. The total mean compliance rate was 82.3%. The mean compliance rate was 83.1% in participants <65 years old and 81.1% in those ≥65 years old. CONCLUSIONS: The system was feasible, usable, and effective, even with elderly participants, for monitoring medication compliance in clinical trials using a PDA with a barcode scanner, and may improve the quality of clinical trials.

BACKGROUND: Advanced information technology can be used when developing diagnostic and treatment strategies to provide better care for diabetic patients. However, the levels of need and demand for the use of technological advances have not been investigated in diabetic patients. We proposed and developed an individualized, ubiquitous (U)-healthcare service using advanced information technology for more effective glucose control. Prior to our service initiation, we surveyed patient needs and other pertinent information. METHODS: During August 2009, we conducted a 34-item questionnaire survey among patients with diabetes who were older than 40 years in two certain hospitals in Korea. RESULTS: The mean age of the 228 participants was 61.2+/-9 years, and males made up 49.1% of the sample. Seventy-one percent replied that they wanted individualized healthcare service, and they also wanted their health information to be delivered through mobile devices such as a cellular phone or a personal digital assistant (40.4%). Most patients had never heard of U-healthcare services (81.1%); however, after explaining the concept, 71.1% of participants responded that they would use the service if it was provided. Despite their willingness, participants were concerned about technical difficulty in using the service (26.3%) as well as the cost of the service (29.8%). CONCLUSION: The current study suggests that more than 70% of diabetic patients are interested in using U-healthcare services. To encourage widespread use, the application program or device of U-healthcare services should be simple, easy to use and affordable while also including a policy for the protection of private information.

PURPOSE: In the present study, the visual discomfort induced by smart mobile devices was assessed in normal and healthy adults. METHODS: Fifty-nine volunteers (age, 38.16 ± 10.23 years; male : female = 19 : 40) were exposed to tablet computer screen stimuli (iPad Air, Apple Inc.) for 1 hour. Participants watched a movie or played a computer game on the tablet computer. Visual fatigue and discomfort were assessed using an asthenopia questionnaire, tear film break-up time, and total ocular wavefront aberration before and after viewing smart mobile devices. RESULTS: Based on the questionnaire, viewing smart mobile devices for 1 hour significantly increased mean total asthenopia score from 19.59 ± 8.58 to 22.68 ± 9.39 (p < 0.001). Specifically, the scores for five items (tired eyes, sore/aching eyes, irritated eyes, watery eyes, and hot/burning eye) were significantly increased by viewing smart mobile devices. Tear film break-up time significantly decreased from 5.09 ± 1.52 seconds to 4.63 ± 1.34 seconds (p = 0.003). However, total ocular wavefront aberration was unchanged. CONCLUSIONS: Visual fatigue and discomfort were significantly induced by viewing smart mobile devices, even though the devices were equipped with state-of-the-art display technology.
