Abstract

Background: Mobile technology has revolutionized the way that behavioral scientists collect, store, and analyze data (Press, 2011). Recent literature has begun to point out the effectiveness of this technology for research in health scenarios (Miller, 2011). Therefore, researchers need to continue exploring the use of specific mobile technology and its relevance to the study of health related issues, particularly physician/patient interactions.

Purpose: The purpose of our study was to document the behavioral manifestations of HIV/AIDS-related stigma in physician/patient interactions.

Methods: In order to achieve the aims of this study, a sequential mix method approach using focus groups and standardized patient technology was implemented. The qualitative phase included 9-focus group composed of 66 participants with an HIV/AIDS diagnosis. A qualitative analysis using iAnnotate-application on the iPad allowed the development of a behavioral manifestation of HIV/AIDS-related Stigma Inventory (BMHASI). The quantitative phase was based on three HIV/AIDS case simulations, which generated 91 video recordings of patient/physician interactions, and the administration of a previously validated scale to assess HIV/AIDS-related stigma attitudes. The stigma scales were completed in vivo by medical students using the iSurvey application on the iPad. Standardized patients also completed the BMHASI. In the third phase, six researchers use the BMHASI developed on iSurvey to evaluate the 91 medical interactions between the medical students and standardized patients.

Results: The preliminary analysis identified eight stigmatizing behaviors manifested by medical students during simulated interactions including: avoid shaking hands to the patient, avoid physical contact needed to perform physical examination required by medical protocol, and excessive physical distance.

Conclusions: The iPad is an emergent and valuable research tool for the behavioral sciences field with great potential for documenting socially stigmatized interactions in the health scenario.

Abstract

High levels of patient retention after first clinical contact contribute to the timely initiation of antiretroviral therapy (ART) and better health outcomes. In Kenya (WelTel Kenya1), a weekly short message service (SMS) text message led to improved ART adherence and viral load suppression.

The objectives of this study are to: 1) determine if the WelTel intervention improves retention in Stage 1 HIV care (patient receives CD4 count results); 2) determine whether the WelTel intervention improves 12-month retention; and 3) evaluate the cost-effectiveness of the WelTel intervention.

A randomized controlled trial will be conducted at the Kibera Community Health Centre in Nairobi, Kenya. Over one year, HIV positive individuals newly enrolling at the clinic will be recruited and randomly allocated to an intervention or control arm (standard care) at a 1:1 ratio. Intervention arm participants will receive a weekly SMS ‘check-in’ to which they will be required to respond within 48 hours. An HIV clinician will follow-up and triage any problems that are identified. Patients will be followed for one year, with a primary endpoint of retention in care at 12 months.

This study is in a pre-enrolment phase; a recruitment target of 686 participants provides 80% power to detect a proportionate difference of 15% in the primary outcome (alpha=0.05). Data will be analyzed according to intention to treat principles. Chi-squared tests will be used for categorical outcomes; and t-tests or Mann-Whitney U tests for continuous outcomes.

The WelTel Retain trial will contribute important information on the effectiveness of an established mHealth intervention to engage patients in care during the first year of HIV care, before initiating ART. Trial results and cost-effectiveness evaluation will inform how WelTel might contribute to the long-term success of PEPFAR-funded programs and towards a sustainable global HIV/AIDS response

Before you start

The first step is to conduct a critical appraisal of existing literature relevant to the research question. Before proceeding further, it is then necessary to consider whether a survey is the most appropriate method to collect the data required to answer the research question.  Appropriate alternatives to surveys include a systematic review or meta-analysis, case-studies, or studies with focus groups. It is beyond the scope of this article to discuss these alternate forms in depth, however, the researcher should be guided by published literature in their topic.  The key steps for survey design will now be discussed. (Refer to figure 1).

Background: Uncorrected-refractive-error (URE) is the leading cause of global visionimpairment (VI); 122.5 million people are estimated VI from URE. NETRA is a $30USD clip-on application for smartphones.

Purpose: To validate the NETRA as an alternative to subjective refraction for potential use in resource-poor countries.

Methods: NETRA uses a pinhole mask attached to a smartphone displaying a spatially resolved pattern to the subject. Refractive error is estimated by the patient subjectively aligning patterns by a touchscreen interface on the smartphone. NETRA was compared to subjective refraction in 34 eyes.

Results: The mean Subjective Spherical Equivalent (SSE) was -0.65D (std 2.79, 95%CI ±0.97) Two-sided T-test showed that mean SSE is not statistically significantly different (two sided t-test; t=1.6742 p=0.1036, 95% CI±0.29) from the mean NETRA Spherical Equivalent (NSE) .  Mean difference of Spherical Equivalents (NSE – SSE) was 0.24D (Std 0.84, 95%CI ±0.29). And NETRA produced a mean VA improvement of 0.44LogMAR (Std 0.52, 95%CI±0.18), or four Snellen lines.

Conclusion:In settings where access to a trained refractionist is not possible, NETRA has the potential to estimate refractive error closely enough to render an individual no longer VI from URE. NETRA is potentially a cost-effective tool in meeting the VISION2020 goals to eradicate avoidable blindness and warrants further testing in resource-poor settings.

DOI:10.7309/jmtm.18


Purpose: To examine scientific evidence on the effectiveness of mobile phone technology in Diabetes Mellitus (DM) care management.

Methods: A systematic review was conducted through literature searches from three electronic databases and was restricted to English-language articles published between January 2002 and March 2012. Studies that used mobile phone intervention and reported changes in diet, physical activity, and blood glucose and /or glycosylated hemoglobin (HbA1c) levels were retrieved. A meta-analysis was conducted for studies with HbA1c measures.

Results: More than 50 articles were screened. Of them, 15 met the review criteria. Of the 15, study sample sizes ranged from 12 to 130 participants aged 8 to 70 years old. Duration of intervention ranged from 1 to 12 months. Overall, significant improvements were observed in blood glucose and/or HbA1c concentration, adherence to medication, healthy lifestyle, and self-efficacy. Twelve of 15 trials, which had serum HbA1c measures, showed an average 0.39% (95%CI: -0.067, -0.721) HbA1c reduction from studies with pre- to post-tests (p=0.018).

Conclusion: Findings from the study provide the evidence that health reminders, disease monitoring and management, and education through mobile phone technology may significantly help improve glycaemic control patients with DM.

Background: Many adolescent mothers experience significant challenges in regulating emotions due to adverse life experiences, which can place adolescent mothers and their children at risk for poor developmental outcomes.  Ambulatory monitoring of stress that also provides immediate feedback using wearable biosensors has the potential to enhance clinician-delivered parenting interventions and help young mothers develop emotion regulatory skills.

Methods: We conducted a pilot study to assess the acceptability, ease of use, and preliminary efficacy of a wearable biosensor, the iCalm sensor band, among a sample of four mothers, ages 15-18 years.  Mothers wore the biosensor for a period of 24-36 hours while engaging in normal, daily tasks (e.g. caring for their child, attending school).  Both quantitative electrodermal activity (EDA) data (via the iCalm sensor band) and qualitative data (via individual semi-structured interviews) were collected.

Results: The adolescent mothers were able to comfortably use and wear the iCalm sensor band.  EDA data were collected and corresponded with stressful daily life events described by the mothers during qualitative interviews.

Conclusion: The iCalm biosensor is acceptable to use among high-risk adolescent mothers and appears to help mothers with the development of emotion regulatory skills.
