In this paper, we propose a medication reminder system using IoT platforms and products to help old adults keep track of their medication schedule, one of 10 Korean instrumental activities in daily living (K-IADL). An interworking architecture based on the oneM2M standard platform is designed to allow various IoT products to be connected each other through interworking proxy entities. A prototype system for the medication reminder service is developed, which consists of a pair of off-the-shelf pill bottle and container box embedded with an NFC tag and reader respectively, three types of actuators including a LIFX LED lightbulb, Musaic speaker, Microsoft Band 2, and smartphone applications. The experiment shows that our medication reminder system can make alarms for old adults to take their pills appropriately considering where they are and when they have food inferred from data collected from sensors including ultrasonic sensor and rice cooker, fostering them to keep their medication routine.

Background and Purpose: Medication adherence is essential for effective medical treatment. However, it is challenging for cognitively impaired patients. We investigated whether an automated telephone reminder service improves medication adherence and reduces the decline of cognitive function in isolated patients with cognitive impairment. Methods: This was a single-center, randomized clinical trial. We enrolled mild cognitive impairment (MCI) or Alzheimer's disease (AD) patients who lived alone or with a cognitively impaired spouse. We provided an automated telephone reminder service for taking medication to the intervention group for 6 months. The control group was provided with general guidelines for taking the medication every month. The participants underwent neuropsychological assessment at the beginning and end of the study. Statistical significance was tested using nonparametric Wilcoxon rank sum and Wilcoxon matched-pairs signed-rank tests. Results: Thirty participants were allocated randomly to groups, and data for 29 participants were analyzed. The mean age was 79.6 (standard deviation, 6.0) years and 79.3% of the participants were female. There was no significant difference in medication adherence between the 2 groups. However, a subgroup analysis among participants with more than 70% response rates showed better medication adherence compared to the control group (intervention: 94.6%; control: 90.2%, p=0.0478). There was no significant difference in the change in cognitive function between the 2 groups. Conclusions: If a patient's compliance is good, telephone reminders might be effective in improving medication adherence. It is necessary to develop reminder tools that can improve compliance for cognitively impaired patients.

Recently, there has been a rapid increase of interest in u-Health systems or instruments. The importance of testbeds has been discussed deeply also. However, beyond laboratory or ward environments, testbeds covering metropolitan area cannot be found easily. Moreover, there has been few papers which discuss the results of testbed operations for various instruments in different age groups. In this paper, the results of testbed which operated in Daegu metropolitan area are discussed and improvement directions to strengthen the competitiveness are proposed using user analysis. In particular, the results of trial services using the u-Life support instruments (medication reminder, falling safety phone, bio-patch and shirts, etc) for super aging societies in the near future are discussed.

Purpose: The purpose of this study was to evaluate the effects of periodic reminding interventions on medication adherence, self-efficacy, and pain intensity for home-based lung cancer patients. Methods: A quasi-experimental nonequivalent control group, pretest and posttest design was used. The intervention comprised of individual education by tailored image-combined medication instructions, daily reminding text message, and weekly telephone calls for four weeks. The subjects in this study consisted of 62 lung cancer patients (31 in the experimental group, and 31 in the control group). Mann-Whitney U-test was applied to analyze the data. Results: Experimental group who received periodic reminding intervention program better adhered to prescribed medication compared to the control group (z=-6.14, p<.001). Experimental group demonstrated higher level of self-efficacy compared to the control group (z=-6.74, p<.001). Experimental group experienced less intense average pain compared to the control group (z=-6.29, p<.001). Conclusion: The findings suggest that periodic reminding interventions can be applied as an effective nursing intervention to promote medication adherence and self-efficacy to improve and pain management for home-based lung cancer patients.
