BACKGROUND Frailty is a highly prevalent condition that predisposes older persons to adverse events. According to the WHO, there is a pressing need to develop comprehensive community-based approaches, and to introduce interventions to prevent functional decline. In this regards, Information and Communication Technologies can play a crucial role to promote ageing in place, for instance by collecting fresh and periodic information on variables associated to poor health outcomes. The CAPACITY technological ecosystem tackles this problem, providing a means to remotely monitor variables with high predictive power for adverse events (ie, gait speed, muscle power and involuntary weight loss) that enable personalized early interventions aimed to prevent disability. OBJECTIVE This study aims to present a novel mobile app designed using a participatory methodology to be used by frail older persons to interact with the services offered by the CAPACITY technological ecosystem, Furthermore, this research work pursues evaluating its usability, user experience and acceptance. METHODS Usability, User Experience and acceptance were assessed at 3 different sampling points during 6 months of continued use of CAPACITY to receive a multicomponent intervention to prevent/reverse frailty. Usability was assessed using the System Usability Scale (SUS); User Experience using the User Experience Questionnaire (UEQ); and acceptance with the Technology Acceptance Model (TAM) and a customized quantitative questionnaire. Data were collected at baseline (recruitment), and after 3 and 6 months of use. RESULTS Forty-six participants used the technology for six months at their homes, and 9 dropped out during the follow-up, leaving a final sample of 37 subjects. All of them completed the questionnaires about usability, user experience and acceptance evaluation in the intermediate and final sample collection points; 25 subjects completed the whole evaluation set at baseline. Usability, measured as SUS reached a maximum averaged value of 83.68 after 6 months of use; no statistically significant values have been found to demonstrate that usability improves with use. User experience, measured as UEQ, obtained averages scores higher or very close to 2 in all 6 categories. Finally, acceptance in terms of TAM reached a maximum of 51.54 points, showing an improvement trend. CONCLUSIONS Results indicate the success of the participatory methodology, and support User Centered Design as the key methodology to follow when designing technologies for frail older persons. Involving potential end users and giving them voice during the design stage maximizes usability and acceptance.

SUS reached a maximum averaged value of 83.68 after six months of use; no statistically significant values have been found to demonstrate that usability improves with use, probably because of a ceiling effect. UEQ, obtained averages scores higher or very close to 2 in all categories. TAM reached a maximum of 51.54 points, showing an improvement trend. Results indicate the success of the participatory methodology, and support user centered design as a key methodology to design technologies for frail older persons.

A user evaluation stage is an integral part of designing an application. A practical evaluation can provide an overview of the problems that arise in the application and improve the user experience. The Kupuku application is an augmented reality (AR)-based game application for learning about butterflies. The Kupuku application is specifically intended for children aged 6-13 years. The user sample was selected using a purposive sampling method with the criteria for users of elementary school-age children for the child user segment and their companions as the adult user segment. This study aims to evaluate the usability of the Kupuku game application to users. User evaluation was carried out to measure the application’s usability. The evaluation process was conducted on two user segments, namely 20 child users and 16 adult users. Assessment of children employed the Fun Toolkit and usability factor-based question - Nielsen method. The obtained results showed positive feedbacks. In contrast, the assessment for adult users utilized the system usability scale (SUS) and the user experience questionnaire (UEQ). The SUS score of 76 was included in the good category, and the UEQ score produced an excellent average. The test results indicate that this application can be accepted by users, both children, and adults.

BACKGROUND Pharmacotherapeutic management of immune-mediated inflammatory diseases (IMID) has become more complex due to the development of new treatments, such as biological therapies. Mobile health, especially apps, can provide IMID patients with greater autonomy and facilitate communication with healthcare professionals. OBJECTIVE Our objective was to design and implement an app for remote monitoring and communication with IMID patients. We also assessed the usability of and satisfaction with the app. METHODS A multidisciplinary group comprising pharmacists, dermatologists, rheumatologists, gastroenterologists, and nurses was created to design and develop an app for IMID patients in a tertiary hospital. The app functionalities were identified through a focus group with IMID patients and through an observational, cross-sectional, descriptive study of all available apps for IMID patients at App Store and Play Store platforms. Once the app was designed and developed, we started offering the app to all IMID patients who initiated a new biological therapy. We performed an observational, longitudinal study of patients followed using the app to assess the tool's impact on safety, communication, satisfaction, and usability. The inclusion period was from December 2020 to August 2021. The inclusion criteria were age ≥ 18 years, diagnosis of an IMID, and ownership of a Smartphone. Patients with language barriers were excluded. RESULTS We designed an app (eMidCare®) with the following modules: My Medication, My Questionnaires, Adverse Events, Useful Information, Messages, and Patient Profile. A total of 86 patients were installed with the app (the median age was 48.3 [18.1-79.4] years and 62.4 were female). The median (range) follow-up time for app use was 123 (5-270) days. In the My Medication module, 100% of patients registered their biological therapy and 25.9% also used this module to record each dose of medication administered. A total of 82 adverse events (AEs) were registered. Thirty-two percent of the patients registered at least 1 AE. The most frequent AEs were fatigue, injection site reaction, headache, and nausea. Fifty-two percent of patients used the Messages module to communicate with healthcare professionals. The most frequent messages concerned doubts about managing AEs (26.2%) and drug interactions (18.9%). The satisfaction survey yielded a median (range) score of 9.1 (7-10) out of 10. The app sections that patients browsed for the longest time were Messages (21.9%), Start screen (20.9%), My questionnaires (20.4%), My medication (8.8%), and Adverse events (7.1%). CONCLUSIONS We developed an app, eMidCare®, which reminds patients to take their medication, enables them to record AEs, and helps them communicate with healthcare professionals. Approximately one-third of the patients registered the administration of the biological therapies and registered at least 1 AE. The most used and most satisfactory functionality was communication with health professionals. Patient satisfaction and retention were very high.

Abstract Interventions utilizing consumer-grade wearable and mobile devices may support older adult health and wellness. However, rapid technology change and short industry product release cycles limit timely incorporation of these devices. We developed a novel, multi-stage process to rapidly move from within-team evaluations to lab- and field-based participants studies based on small-sample technology testing methods from Human-Computer Interaction. We present findings from a first-stage evaluation of the Amazfit Bips smart watch for potential use in studies with older adults as part of the methodology validation. A four-person research team conducted evaluations using: 1) a wearables framework for user experience and feature availability; and 2) the System Usability Scale (SUS). Evaluators wore the watch seven days straight from the box. User experience checklists indicated high usability. However, corresponding comments identified challenges with downloading the mobile app, pairing the watch and phone, navigating watch and mobile interfaces, and privacy controls. Average SUS score was 65.6 indicating marginal usability (C grade). While meeting study goals, divergence in usability perceptions suggest the process could be improved by completing each set of instruments separately for the watch and mobile app rather than all at once. Given failures in pairing, app navigation challenges, and small screen size, the Amazfit Bips may be best suited for studies among older adults with a high degree of technical proficiency. For those with little technical experience or high disease burden, training materials and dedicated training with support may be required. Future steps are lab- and field-based tests with older adult participants.

Abstract Caregiving and self-care are challenging for Chinese immigrants in the U.S. due to limited accessible support and resources. The team developed a Care Me Too app for engaging Chinese immigrant caregivers in self-care and conducted a user-experience test to assess its usability and acceptability. The aims of this paper are to report the testing results and develop guidelines to support mHealth app design for immigrant caregiver populations. Twenty-two Chinese caregivers participated in the test, which consisted of two parts: in-lab testing and one-week at-home testing. In-depth face-to-face interviews and follow-up phone interviews were used to test the app’s usability and acceptability and solicit participants’ feedback for app design and functions. Directed content analysis was used to analyze testing transcripts. Participants reported uniformly positive ratings of usability and acceptability of the app and provided detailed suggestions for app improvement. We generated some mHealth app design guidelines, including weighing flexibility vs. targeting majority preferences, increasing text sizes, using colors effectively, providing engaging and playful visual designs and functions, simplifying navigation, simplifying login process, design functions to cater to the population’s context, etc. We concluded that culturally and linguistically appropriate mHealth apps are appealing to immigrant caregivers for health promotion.

Vaginal microbicides for the prevention of HIV transmission maybe an important option for protecting women from infection.Incorporation of dapivirine, a lead candidate nonnucleoside reversetranscriptase inhibitor, into intravaginal rings (IVRs) for sustainedmucosal delivery may increase microbicide product adherence andefficacy compared with conventional vaginal formulations. Twentyfourhealthy HIV-negative women 18–35 years of age were randomlyassigned (1:1:1) to dapivirine matrix IVR, dapivirine reservoir IVR,or placebo IVR. Dapivirine concentrations were measured in plasmaand vaginal fluid samples collected at sequential time points over the33-day study period (28 days of IVR use, 5 days of follow-up). Safetywas assessed by pelvic/colposcopic examinations, clinical laboratorytests, and adverse events. Both IVR types were safe and well toleratedwith similar adverse events observed in the placebo and dapivirinegroups. Dapivirine from both IVR types was successfully distributedthroughout the lower genital tract at concentrations over 4 logs greaterthan the EC50 against wild-type HIV-1 (LAI) in MT4 cells. Maximumconcentration (Cmax) and area under the concentration–time curve(AUC) values were significantly higher with the matrix than reservoirIVR. Mean plasma concentrations of dapivirine were ,2 ng/mL.These findings suggest that IVR delivery of microbicides is a viableoption meriting further study.Key Words: dapivirine, HIV, intravaginal ring, microbicide,pharmacokinetics, prevention

Abstract Background Community-dwelling older persons with cognitive impairment (CI) following discharge from geriatric rehabilitation are at high risk of losing life-space mobility (LSM). Interventions to improve their LSM are, however, still lacking. The aim of this study was to evaluate the effects of a CI-specific, home-based physical training and activity promotion program on LSM. Methods Older persons with mild-to-moderate CI (Mini-Mental State Examination: 17–26 points) discharged home from rehabilitation were included in this double-blinded, randomized, placebo-controlled trial with a 12-week intervention period and 12-week follow-up period. The intervention group received a CI-specific, home-based strength, balance, and walking training supported by tailored motivational strategies. The control group received a placebo activity. LSM was evaluated by the Life-Space Assessment in Persons with Cognitive Impairment, including a composite score for LSM and 3 subscores for maximal, equipment-assisted, and independent life space. Mixed-model repeated-measures analyses were used. Results One hundred eighteen participants (82.3 ± 6.0 years) with CI (Mini-Mental State Examination: 23.3 ± 2.4) were randomized. After the intervention, the home-based training program resulted in a significant benefit in the Life-Space Assessment in Persons with Cognitive Impairment composite scores (b = 8.15; 95% confidence interval: 2.89–13.41; p = .003) and independent life-space subscores (b = 0.39; 95% confidence interval: 0.00–0.78; p = .048) in the intervention group (n = 63) compared to control group (n = 55). Other subscores and follow-up results were not significantly different. Conclusions The home-based training program improved LSM and independent life space significantly in this vulnerable population. Effects were not sustained over the follow-up. The program may represent a model for improved transition from rehabilitation to the community to prevent high risk of LSM restriction.
