Objective:To evaluate the correlation, consistency and safety of an smartphone application (APP) in screening neonatal jaundice using the smartphone based on the image-based bilirubin (IBB) and transcutaneous bilirubin (TcB).Methods:From July to October 2018, neonates with the age ≤28 d and gestational age ≥35 weeks who were admitted to Department of Neonatal and Obstetrics, Xuzhou Central Hospital without blue light phototherapy were recruited.They were randomly divided into two groups to measure the jaundice value of skin in front of sternum by a cross-control analysis.Jaundice level in group Ⅰ was first measured using the Nezhabaobei? APP in iPhone 6, and then measured using the JM-103 transcutaneous jaundice instrument as the control device.In group Ⅱ, jaundice level was sequencially measured by the control device and the Nezhabaobei? APP.Sex, age, gestational age, birth weight and the mean value of three consecutive tests were recorded.The Pearson′s correlation analysis, Bland-Altman plots consistency analysis, t test and receiver operating characteristic (ROC) curve were used for statistical analysis. Results:A total of 185 eligible neonates were enrolled, including 99 males and 86 females, with the median age of 5 d (3-8 d), gestational age of (37.6 ± 1.7) weeks, and birth weight of (2 950 ± 645) g. There were good correlation ( r=0.860, P<0.05) and consistency (95.1% of the samples fall within the 95% consistency interval) between IBB and TcB.Good correlation and consistency were also yielded in subgroup analyses based on the sex, age, gestational age and birth weight.The consistency was better in subgroups of ≤7 d, >37 weeks and>2 500 g. The ability of IBB to predict TcB>256.5 μmol/L was better than that of TcB>171.0 μmol/L.The area under the ROC curve was 0.93, the cut-off value was 232.6 μmol/L, the sensitivity was 96.7%, and the specificity was 82.6%.The difference of the mean values of IBB and TcB detected for 3 times was significantly lower than that obtained in the first measurement of IBB and TcB [(12.0 ± 34.4) μmol/L vs.(14.4 ± 38.6) μmol/L, P=0.038]. There were no adverse events and no defects in the device itself. Conclusions:There are good correlation and consistency between IBB and TcB.The ability of IBB to predict TcB>256.5 μmol/L is better than that of TcB>171.0 μmol/L, which is safe in clinical use.

OBJECTIVES: Snacks contribute to the diet quality in youth, which is often poor. Although the US Department of Agriculture (USDA) has guidelines for healthy snacks, this is lost in translation when youth are choosing snacks. To develop a userfriendly app to help identify healthy snacks based on the US Department of Agriculture guidelines and evaluate the app's feasibility, usability, satisfaction, and acceptability. METHODS: The ‘Snackability’ app was developed following the ADDIE (analysis, design, development, implementation, and evaluation) model. The app was pilot tested for 2 weeks among college-age students (18–24 years) using questionnaires and focus groups. Based on the feedback received, the app was improved, and pilot-tested again. RESULTS: The app had a simple score (−1 to 11) and feedback (the higher the score, the healthier the snack is). The 1st pilot test among 12 students showed that the app's feasibility and usability were >50% (p 50% (p < 0.05). Additional suggestions were to include images for serving size, snack alternatives, and barcode scanning, which were incorporated into the 3rd version. CONCLUSIONS: Snackability app was feasible, usable, satisfactory, and acceptable, and several features were improved as suggested by participants.

Development and Application of Professional Care APP for Stroke Patients at Home / 中国康复理论与实践

Objective:To develop and evaluate the effect of Professional Care APP for stroke patients at home. Methods:Professional Care APP 1.0 was developed by reviewing literature, analyzing APP function and consulting expert, and combined with the findings at the early stage. And then it was upgraded to APP 2.0 after a 4-week trial in 10 stroke patients at home, which included two parts: patient-side and medical-side. The patient-side provided health education, rehabilitation guidance, medication reminder, online consultation and so on. From December, 2017 to June, 2018, 77 stroke patients in a community in Zhengzhou, China were conveniently selected and randomly divided into control group (n = 39) and intervention group (n = 38). The control group received routine community follow-up, and the intervention group received Professional Care APP 2.0, for 12 weeks. Results:After a 12-week intervention, the level of knowledge and medication compliance was significantly higher in the intervention group than in the control group (t > 4.205, P < 0.001). The score of demand for professional care was significantly lower in the intervention group than in the control group (t = -18.183, P < 0.001). The intervention group made a good evaluation for APP in usefulness, ease of learning, usability, credibility, acceptability and satisfaction. Conclusion:Professional Care APP can meet the professional care needs, and improve the level of knowledge on disease and medication compliance for stroke patients at home. The patients' evaluation for APP is ideal.

Mobile Real-time Tracking of Acute Stroke Patients and Instant, Secure Inter-team Communication - the Join App / 신경중재치료의학

PURPOSE: The primary correlate to survival and preservation of neurologic function in patients suffering from an acute ischemic stroke is time from symptom onset to initiation of therapy and reperfusion. Communication and coordination among members of the stroke team are essential to maximizing efficiency and subsequently early reperfusion. In this work, we aim to describe our preliminary experience using the Join mobile application as a means to improve interdisciplinary team communication and efficiency. MATERIALS AND METHODS: We describe our pilot experience with the initiation of the Join mobile application between July 2015 and July 2016. With this application, a mobile beacon is transported with the patient on the ambulance. Transportation milestone timestamps and geographic coordinates are transmitted to the treating facility and instantly communicated to all treatment team members. The transport team / patient can be tracked en route to the treating facility. RESULTS: During our pilot study, 62 patients were triaged and managed using the Join application. Automated time-stamping of critical events, geographic tracking of patient transport and summary documents were obtained for all patients. Treatment team members had an overall favorable impression of the Join application and recommended its continued use. CONCLUSION: The Join application is one of several components of a multi-institutional, interdisciplinary effort to improve the treatment of patients with acute ischemic stroke. The ability of the treatment team to track patient transport and communicate with the transporting team may improve reperfusion time and, therefore, improve neurologic outcomes.

Development of Smartphone Application for Cognitive Behavioral Therapy-Based Case Management in Patients with Schizophrenia / 대한정신분열병학회지

OBJECTIVES: This article aims to describe the development of smartphone application for the case management of patients with schizophrenia. METHODS: Gwangju Bukgu-Community Mental Health Center developed and launched a smartphone application (HYM) for cognitive-behavioral case management and symptom monitoring. The development of the application involved psychiatrists, nurses, social workers, psychologists, and software technicians from a software development company (Goosl Corp.). RESULTS: The HYM application for clients includes six main modules including Thought record, Symptom record, Daily life record, Official notices, Communication, and Scales. The key module is the 'Thought Record' for self-directed cognitive-behavioral treatment (CBT). When the client writes and sends the self-CBT sheet to the case manager, the latter receives a notification and can provide feedback in real time. 'Communication' and 'Official notices' are useful for promoting communication between case managers and clients with schizophrenia. Ratings in 'Symptom record', 'Daily life record', and 'Scales' modules are stored in graphic or table form representing changes in them and shared with case managers. CONCLUSION: The interactive function of this application is the key characteristics that distinguishes it from other mobile self-treatment tools. This smartphone application may contribute to the development of a youth- and customer-friendly case management system for individuals with early psychosis.

Development of a Smartphone Application Prototype for Child Obesity Prevention: Rationale and Study Design of Acceptability and Feasibility Tests

BACKGROUND: There have been many efforts to rectify lifestyles that contribute to obesity using a variety of methodologies in heterogeneous settings, but effective and sustainable interventions that are suitable for children are still needed. We developed a smartphone application called "HAPPY ME" for guiding health behavior decisions, which employs gamification and self-monitoring strategies. The aim of this paper is to outline the rationale and methods for the development and feasibility test of "HAPPY ME". METHODS: The study consisted of two phases: 1) description of theory-based conceptual framework and rationales for smartphone application development and 2) outline of a pre- and post-test design in 4th-6th grade of healthy elementary school students for 4 weeks. The students will be delivered missions or messages on a daily basis, which is to stretch the knowledge and skills for action. They will simultaneously be engaged in self-monitoring their eating and physical activities to clear daily quests. To measure acceptability and feasibility we will monitor usability, compliance, and satisfaction for a 4-week study period and evaluate the intervention effects on self-efficacy, readiness, and intention to engage in healthy behavior. CONCLUSIONS: The results of the feasibility study will show whether the smartphone application "HAPPY ME" for children is acceptable, as well as if it is usable and feasible for self-directed health management. The results will provide preliminary evidence of the effectiveness of smartphone application-supported child behavioral modification for child obesity prevention and management.
