Abstract

Background

The prevalence of surgical diseases in low income countries is thought to be very large, but to date no population-based survey has documented the need. The Surgeons OverSeas Assessment of Surgical Need (SOSAS) is a survey tool programmed for use with iPads to measure the prevalence of surgical conditions.

Methods

To assess the appropriateness and utility of SOSAS, a pilot test was undertaken in Sierra Leone. Local medical students were trained in sampling, interviewing, and SOSAS specifics. Five clusters of 10 households were randomly selected and 100 individuals were interviewed. Problems with the tool, iPad use, and respondent answers were collected. Daily debriefings with the enumerators aimed to identify problems and ways for improvement.

Results

Administering SOSAS via iPads was found to be easy and facilitated data entry. Quick analysis of the data allowed for rapid feedback. Although the survey has 450 possible data entry points, by using conditional formatting, the enumerators were able to collect household demographics and interview two randomly selected household members in an average of 25 min. The survey methodology was acceptable, with a response rate of 96%. Five major sections were amended after the pilot.

Discussion

Pilot testing of SOSAS showed that a population-based survey measuring the prevalence of surgical disease could be undertaken in a low income country. It is recommended that SOSAS be used with a larger sample size to calculate the prevalence of surgical disease in low income countries.
