Explaining Differences in the Acceptability of 99DOTS, a Cell Phone-Based Strategy for Monitoring Adherence to Tuberculosis Medications: Qualitative Study of Patients and Health Care Providers.

BACKGROUND: 99DOTS is a cell phone-based strategy for monitoring tuberculosis (TB) medication adherence that has been rolled out to more than 150,000 patients in India's public health sector. A considerable proportion of patients stop using 99DOTS during therapy. OBJECTIVE: This study aims to understand reasons for variability in the acceptance and use of 99DOTS by TB patients and health care providers (HCPs). METHODS: We conducted qualitative interviews with individuals taking TB therapy in the government program in Chennai and Vellore (HIV-coinfected patients) and Mumbai (HIV-uninfected patients) across intensive and continuation treatment phases. We conducted interviews with HCPs who provide TB care, all of whom were involved in implementing 99DOTS. Interviews were transcribed, coded using a deductive approach, and analyzed with Dedoose 8.0.35 software (SocioCultural Research Consultants, LLC). The findings of the study were interpreted using the unified theory of acceptance and use of technology, which highlights 4 constructs associated with technology acceptance: performance expectancy, effort expectancy, social influences, and facilitating conditions. RESULTS: We conducted 62 interviews with patients with TB, of whom 30 (48%) were HIV coinfected, and 31 interviews with HCPs. Acceptance of 99DOTS by patients was variable. Greater patient acceptance was related to perceptions of improved patient-HCP relationships from increased phone communication, TB pill-taking habit formation due to SMS text messaging reminders, and reduced need to visit health facilities (performance expectancy); improved family involvement in TB care (social influences); and from 99DOTS leading HCPs to engage positively in patients' care through increased outreach (facilitating conditions). Lower patient acceptance was related to perceptions of reduced face-to-face contact with HCPs (performance expectancy); problems with cell phone access, literacy, cellular signal, or technology fatigue (effort expectancy); high TB- and HIV-related stigma within the family (social influences); and poor counseling in 99DOTS by HCPs or perceptions that HCPs were not acting upon adherence data (facilitating conditions). Acceptance of 99DOTS by HCPs was generally high and related to perceptions that the 99DOTS adherence dashboard and patient-related SMS text messaging alerts improve quality of care, the efficiency of care, and the patient-HCP relationship (performance expectancy); that the dashboard is easy to use (effort expectancy); and that 99DOTS leads to better coordination among HCPs (social influences). However, HCPs described suboptimal facilitating conditions, including inadequate training of HCPs in 99DOTS, unequal changes in workload, and shortages of 99DOTS medication envelopes. CONCLUSIONS: In India's government TB program, 99DOTS had high acceptance by HCPs but variable acceptance by patients. Although some factors contributing to suboptimal patient acceptance are modifiable, other factors such as TB- and HIV-related stigma and poor cell phone accessibility, cellular signal, and literacy are more difficult to address. Screening for these barriers may facilitate targeting of 99DOTS to patients more likely to use this technology.

Evaluation of the Accuracy of 99DOTS, a Novel Cellphone-based Strategy for Monitoring Adherence to Tuberculosis Medications: Comparison of DigitalAdherence Data With Urine Isoniazid Testing.

99DOTS is a cellphone-based strategy for monitoring tuberculosis medication adherence. In a sample of 597 Indian patients with tuberculosis, we compared 99DOTS' adherence assessments against results of urine isoniazid tests collected during unannounced home visits. 99DOTS had suboptimal accuracy for measuring adherence, partly due to poor patient engagement with 99DOTS.

Awareness on Hypertension and its Self-Management Practices Among Hypertensive Patients Attending Outreach Clinics of a Medical College in South India.

Background Recent data suggest that hypertension is a significant public health problem in India. The success strategies for hypertension management depend upon clients' awareness on hypertension and its self-management practices. Objective To determine awareness, self-management practices and compliance with treatment among hypertensive patients. Method This cross-sectional study was done in January 2012 at four health centres in Mangalore. All confirmed cases of hypertension attending the outpatient department were interviewed using a semi-structured interview schedule. Result Majority (58.7%) of the 315 participants were of the age group 41 to 60 years and majority (53.6%) were males. Most patients (69.5%) were educated up to high school level. The awareness level about hypertension was average or good in majority (52.4%) of the participants. Self-management practices were found to be average or good among 60.6% cases. Good compliance with treatment was seen in 78.7% cases and blood pressure was in control in 72.4% cases. Quality of self-management practices was found to influence control of blood pressure (p=0.021). Awareness, self-management practices and compliance were found to be significantly poor among aged (above 50 years), males, less educated, unemployed, unskilled or retired patients. Conclusion Awareness on hypertension and self-management practices were average or above among majority of the studied population. However this study identified groups who need to be better educated and further monitored to achieve universal blood pressure control among hypertensive population during the routine health care services in this settings.
