Factors influencing operationalization of Integrated Disease Surveillance in Malawi.

OBJECTIVES: Malawi's disease surveillance system is built on several different data sources and systems and is informed by the Integrated Diseases Surveillance and Response (IDSR) strategy. This study was carried out as part of a larger multicountry study to identify context-specific factors, which influence the operationalization of integrated disease surveillance. STUDY DESIGN AND METHODS: A total of six focus group discussions were conducted with 43 relevant personnel at the primary and secondary healthcare levels in two districts (Lilongwe and Dowa) and at the national level. The discussions were analyzed and sorted into predefined categories based on the domains of the International Association of Public Health conceptual framework. RESULTS: We found ongoing efforts to enhance integrated disease surveillance operationalization, including the establishment of the Public Health Institute of Malawi for coordination, digitalizing the surveillance system through One Health Surveillance Platform, and improving communication among rapid response teams using WhatsApp. The adoption of World Health Organization's third edition IDSR technical guidelines was also underway. Nonetheless, there were major implementation barriers such as parallel and uncoordinated surveillance systems, priority conditions that cannot be diagnosed at the point of reporting, lack of case definitions and diagnostic codes for priority conditions, reporting forms with unexplained acronyms, illegible data sources, unstable electronic data transfers, inadequate supervision and training, poor enforcement of reporting from private health facilities, high reporting burden, and lack of and feedback to those reporting. CONCLUSIONS: The results fit well into the predefined categories used. The study reveals basic problems with the operationalization, tools, and reporting forms used for IDSR. These findings may have implications for practice and policy in Malawi and other countries where IDSR is the national strategy for surveillance.

Assessing the Acceptability, Feasibility, and Effectiveness of a Tablet-Based Cervical Cancer Educational Intervention.

Cervical cancer is a common and deadly disease, especially in developing countries. We developed and implemented an interactive, tablet-based educational intervention to improve cervical cancer knowledge among women in rural Malawi. Chichewa-speaking adult women in six rural villages participated. Each woman took a pretest, participated in the lesson, and then took a posttest. The lesson included information on cervical cancer symptoms, causes, risk factors, prevention, and treatment. Over the 6-month study period, 243 women participated. Women ranged in age from 18 to 77 years. Only 15 % had education beyond primary school. Nearly half of participants (48 %) had heard of cervical cancer prior to viewing the lesson. For these women, the median number of correct responses on the pretest was 11 out of 20; after the lesson, they had a median of 18 correct responses (p < 0.001). After the intervention, 93 % of women indicated a desire for cervical cancer screening. Despite lack of familiarity with computers (96 %), most women (94 %) found the tablet easy to use. A tablet-based educational program was an effective, feasible, and acceptable strategy to disseminate cervical cancer information to women with low education in rural Malawi. This method may be appropriate to distribute health information about other health topics in low-resource settings.

Feasibility and validity of the ActiGraph GT3X accelerometer in measuring physical activity of Malawian toddlers.

AIM: To test the feasibility and validity of the ActiGraph GT3X accelerometer in measuring physical activity of rural Malawian toddlers. METHODS: Fifty-six children aged 16.0-18.5 months wore the accelerometer on their right hip for 7 days. We analysed days with a minimum of 600 min of wear time, excluding night time and periods when the unit registered zero for 20 consecutive minutes. The first and last days were excluded as they were incomplete. Accelerometer counts were compared with coded free play video recordings to define median accelerometer counts for sedentary, light, moderate and vigorous activity. Count cut points were defined for moderate to vigorous physical activity, with predictive validity assessed using a second set of video recordings. RESULTS: Median wear time was 797 min/day, with 79% of participants completing at least four eligible days. Accelerometer counts were significantly higher for observed moderate to vigorous physical activity, than lighter activity, with cut points of 208 counts/15 sec for vector magnitude and 35 counts/15 sec for vertical axis, showing sensitivity of 94.2% and 84.1% and specificity of 90.9% and 84.6%, respectively. CONCLUSION: The accelerometer proved a feasible and valid method of assessing physical activity among Malawian toddlers.
