Abstract

Background: Computer-based HIV education has been shown effective and is preferred over counselor-delivered education. Previous studies have shown significant increases in risk-reduction behaviors after participation in a computerized HIV risk reduction (HIVRR) intervention. Whether delivery of mobile HIVRR (mHIVRR) education via smartphone is also effective at increasing knowledge and decreasing risk behavior has yet to be determined.

Purpose:  To develop and deploy an interactive mHIVRR software program to deliver HIV/STD education on smartphones and determine whether it reduces HIV/STD-related risk via increased HIV/STD knowledge.

Methods: We developed mHIVRR modules using video components of pre-existing evidence-based programs. Each module consists of a 5-10¬–minute video component followed by an 11-item usability/acceptability questionnaire and a 3-item knowledge questionnaire. New modules were downloaded onto smartphones weekly. Participants completed questionnaires after each viewing of ≥75% of the video component. Prior week modules were moved to the “Library” and available for repeated viewing. Acceptability of mHIVRR modules was defined as a median score of ≤2.5 (1-very easy/effective to 5-very hard/not at all effective) for each usability/acceptability question. Effectiveness was defined as ≥80% of participants scoring >65% on the knowledge questions.

Results: 78% of video modules attempted were completed. Average usability/acceptability questionnaire responses were all ≤2.5 (range 1.3 to 2.1). Video module length was “just right” according to 72% of participants. Only 16% thought the mHIVRR module information would have been better suited for printed material and 28% for computer-based delivery. 25% of participants would have preferred a text-based smartphone module compared to the video-based smartphone module. 100% of participants scored >65% on the knowledge questions, with an average overall knowledge score of 82%.

Conclusions: Video-based mHIVRR education delivered via smartphone appears to be acceptable, and may increase HIV/STD risk reduction knowledge. Future studies, with pre-intervention assessments of knowledge, are needed to confirm these findings.

Abstract

The Office of Cyber Infrastructure and Computational Biology (OCICB) of the National Institute of Allergy and Infectious Diseases (NIAID) at the NIH has been developing a solution that complies with current guidance frameworks and regulatory requirements while leveraging the potentials offered by mHealth technologies for data collection. OCICB has designed an mHealth solution that maps to the paper processes developed over the past century for clinical research. We designed the system for use in regions of low to middle-income countries where the patients often have no other clinical record. For our pilot, we selected a natural history study that does not have the same regulatory requirements as an Investigational New Drug (IND) study. We retained our existing paper-based clinical data capture management system in order to compare quality control reports between paper-based and mobile electronic capture methods. The solution complies with regulatory frameworks and requirements such as Good Clinical Practices and 21 CFR Part 11, which requires full audit trails of the data collection process at the source and the validation stages. It also provides the capacity for workflows that support the data validation process within the field research framework. We expect to show that the accuracy of data collection improves using mobile source data collection. This will reduce the time and cost of validating the collected data before final analysis for clinical research while maintaining the regulatory framework that protects patient interests. The solution will further provide clinical monitors with the ability to remotely access the source data and thus reduce the cost of travel for monitoring as well as reducing the impact on patients due to mistakes made while entering the data.

Abstract

Over 8.8 million people become ill and1.4 million people die annually from tuberculosis (TB). TB is treatable with antibiotics; however,poor adherence to daily medication regimens lasting >6 months promotes ongoing disease transmission, higher mortality, and development of drug resistance. “Directly observed therapy” (DOT) is recommended to minimize these problems. DOT healthcare providers watch patients take each dose of medication, hence DOT is costly, time consuming, invasive for patients, and is limited to patients who live near a health center. Informed by focus groups and expert opinions among patients and providers, we developed and pilot- tested a method called Video DOT (VDOT) whereby patients use mobile phones to record and securely transfer time-stamped videos of themselves taking their medications, which are then watched remotely by their provider. The study was conducted in San Diego, CA (n=43) and Tijuana, Mexico(n=9). To date, 38 patients have completed TB treatment using VDOT. Patient ages ranged from 18 to 86 years, 54% were male, and 77% were non-white. Overall, 90% and 97% of the expected videos were received on-schedule from patients in San Diego and Tijuana respectively. Post-treatment interview responses were similar across cities. Patients and providers easily adopted the technology. Patients required only 3 training sessions on average before being able to perform VDOT independently. Overall, 89% of patients reported never or rarely having problems recording videos, 92% preferred VDOT over in-person DOT, and 81% thought VDOT was more confidential. All patients said they would recommend VDOT to other TB patients. Three participants were more compliant after switching to in-person DOT, suggesting the need for both DOT options. VDOT provides a promising mobile solution to the high cost and burden of in-person DOT for monitoring TB and other conditions that require strict treatment adherence.

Abstract

African Americans are disproportionately more susceptible to Hypertension (HTN) than non-Hispanic Whites, which is a leading cause of cardiovascular disease. Poor adherence to prescribed medication regimens is a major contributor to HTN, as only about half of patients are adherent. Moreover, while the majority of HTN treatment is delivered in primary care settings, a sizable proportion of care is provided in the emergency department (ED), particularly within low income communities. Short Message Service (SMS) text messaging may offer a simple, non-labor intensive strategy for improving medication adherence among African Americans in both primary care and ED settings, as text message use within this population is widely integrated into everyday life, even among the lowest income levels. The goal of this evaluation is to determine intervention efficacy, as well as to establish the feasibility and acceptability of using an automated SMS intervention to improve medication adherence in African Americans with uncontrolled HTN in these settings.

We recently launched two randomized controlled trials (RCTs) of uncontrolled hypertensive African Americans in Detroit, MI; one with participants from primary care clinics, and one with participants from an ED. The primary outcome measure is change in medication adherence from baseline to one-month follow-up. Secondary outcome measures include changes in blood pressure and medication self-efficacy, participant satisfaction and acceptability, and feasibility of use in our target population. We have currently enrolled 9 participants in the primary care RCT and 7 participants in the ED RCT (target n=70 in each RCT) and preliminary evaluation results are forthcoming. Although the evaluation is ongoing, several lessons regarding the conduct of mHealth research within limited resource settings have been learned including overcoming recruitment and enrollment barriers, challenges associated with utilizing SMS-based interventions with low-income targeted mobile phone carriers, and strategies for retaining participants from baseline to one-month follow-up.

Abstract

Using a standardized set of medical terminologies can help organize EMR content and facilitate patient care, follow-up and documentation in countries with many official languages. A controlled medical vocabulary of clinical terms from patient-provider encounters was developed from submissions of members of the medical community in the Philippines. Crowdsourcing may be useful for building standardized medical terminologies. It also increases awareness on MeSH, SNOMED CT and the UMLS.

Introduction: There is a need for a standardized set of medical terminologies to avoid loss of translational integrity of the chief complaint. A controlled medical vocabulary will be useful for a country like the Philippines which has eight major languages. Using the patient’s exact words of the chief complaint is crucial since it often leads to a diagnosis. This study describes the development of a cross-language tool in the Philippines using mobile devices.

Methods: We announced a call through social media for submission of translations of medical terms. Healthcare personnel could either manually enter a medical term and its translation to one of the eight languages, or provide a translation of a MeSH term after selecting one from the following categories: Disease, Signs and Symptoms, Pharmaceutical Preparations, Health Occupations, Diagnosis, Therapeutics, and Other. Experts from the University of the Philippines Center for Filipino Languages (SentrongWikang Filipino) will validate the translations. If a MeSH term has multiple submitted translations, the experts choose the best one from the entries.

Results and Discussion: A standardized controlled medical vocabulary for the Philippines was developed using a mobile- friendly interface. To date, the database contains 2,447 translations. Filipino (29.87%), Pampangueno (13.11%) and Bicolano (13.04%) are the top three languages with the most translations. Current efforts are focused on validation and deduplication of translations. There is still a need to intensify crowdsourcing efforts to populate the database and to include translation of terms from the Core Problem List Subset of SNOMED CT.

Conclusion: A standardized medical vocabulary will be useful for integrating to patient information in the vernacular with EMR implementations. This will be also be useful for searching knowledge databases such as MEDLINE/PubMed for retrieving of journal citations. Crowdsourcing leverages the medical community around this effort in a highly mobile phone-using population. Future directions include linking the vocabulary to a database of reference images of medical conditions to enhance its usefulness as a clinical reference.
