This reduces the loss to follow-up and recall biases, and improves the quality of data. However, frequent rounds of data collection may risk creating community fatigue. To prevent this, we are establishing a community advisory board.
This board will collaborate and engage community participation to maintain a good relationship between the study team and the community. We have developed a de novo online electronic data system that captures longitudinal data from both household and facility visits, to accommodate low internet bandwidth.
The low internet bandwidth in Ethiopia and the rural study area has created occasional difficulties with data transfer; however, the study team has adapted data transfer strategies that are offline and encrypted during internet outages. The study follows an open cohort design to capture the population dynamics in a region of the world that has historically been challenging for the conduct such type of studies. As a result, the high in- and out-migration in the area, coupled with the size of the study population, pose analytical challenges to defining a steady-state population.
To calculate rates, a mid-year population was used. Birhan HDSS is open to opportunities for collaborative research both nationally and internationally. All researchers who wish to access Birhan data can complete a Birhan data request form and submit it for decision by the Birhan DAC. Datasets will only be provided with de-identified data, to maintain confidentiality of study participants. Requests for data can be sent to the principal investigators at [ birhan sphmmc.
