Development of OSOMO Prompt Mobile Application on Elderly Population for Village Health Volunteers Using the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) Model.

This paper aims to describe the use ADDIE model in developing a digital health tool, OSOMO Prompt app, and discuss evaluation outcomes of using this digital tool by village health volunteers (VHV) in rural areas in Thailand. The OSOMO prompt app was developed and implemented in elderly populations in eight rural areas. The Technology Acceptance Model (TAM) was used to test the acceptance of the app four month after the implementation. There were 601 VHVs voluntarily involved in the evaluation phase. The ADDIE model was successfully employed to guide the research team to develop the OSOMO Prompt app consisting of four services delivered to elderly populations by VHVs, including: 1) health assessment; 2) home visit; 3) knowledge management; and 4) emergency report. The findings from the evaluation phase reported that the OSOMO Prompt app was accepted as utility and simplicity (score 3.95+.62); and valuable digital tool (score 3.97+.68). The app received the highest score for being a useful tool assisting VHVs in achieving their work goals and improving work performance (score 4.0+.66). The OSOMO Prompt app could be modified for other healthcare services in different populations. Further investigation in long-term use and its impact on healthcare system is warranted.

Implementation of a Geographic Information System-Based Smartphone Application for Health Vigilance in Older Adults by Village Health Volunteers (OSOMO).

This paper mainly studies the smartphone application for health vigilance in elderly adults, based on geographic information system (GIS) for village health volunteers (OSOMO in Thai) to monitor elderly's health. Eight areas from 4 provinces of 7th health territory (Roi Et, Khon Kaen, Maha Sarakham, and Kalasin) were employed for research. The smartphone application called "OSOMO Prompt" was created for both iPhone (iOS) and Android devices for 1,246 OSOMOs. The comparison results of the difference of mean scores of knowledge of before and after using the "OSOMO Prompt" smartphone application, showed that the trial group, 240 elderly participants had the mean scores after smartphone application use of 1.69, higher than before use smartphone application. The results also indicated a statistically significant difference (p-value < .001) at 95%, confidence interval between 2.15-1.22. In conclusion, the "OSOMO Prompt" smartphone application was proved as a tool for village health volunteers to make health decision for the elderly persons. Moreover, the system was easy to use and could improve the quality of the elderly's healthcare.

Acceptability and Feasibility of Smart Phone Application "OSOMO Prompt" for Health Surveillance in Older Adults by Community Health Workers.

The magnanimous functionalities and flexibility of smartphone device make them well suited for collecting field data, especially for the local healthcare professional. This paper describes the results of the acceptability and feasibilityfor community health workers (CHWs) after using smartphone application called 'OSOMO prompt' app. The results indicated that the comparison of means of one sample t-test responses to the questions on the perceived usefulness and perceived ease of use of 'OSOMO prompt' app. The CHWs found that the high average scores of using the 'OSOMO prompt' app were useful in their job (mean=3.97±.68) and easy to use (Mean=3.95±.62). The app also had high score point of improving the quality of CHWs work, easy to do CHWs job, clearly and stability app while all items of perceived usefulness and perceived ease of use were statistical significantly (p-value <.001). In conclusion, challenging of smartphone 'OSOMO prompt' app was feasible and acceptable to CHWs.

Geographic Information System-Based Mobile Application Design for Health Care in Older Persons in Rural Community by Village Health Volunteers.

Health care for older persons is important for their well-being. In Thailand, village health volunteers (VHVs) play a crucial role in communicating between the older persons and health care professionals. Traditionally, they record and submit a monthly report as papers. This project was aimed to design a geographical information system (GIS)-based mobile application for health care in older persons in rural community by the VHVs. As a part of the analysis, design, development, implementation, and evaluation (ADDIE) model, health information obtained from 8,348 older persons and 1,125 VHVs living in rural community were analyzed and used for the for iPhone (iOS) and Android devices, and web browser. In summary, this mobile application allows the VHVs locate the older person's addresses and communicate with health care staff online in time-saving manner.
