Quantifying the Burden of Unmet Upper Extremity Care Need in Low-Middle Income Countries: A Four-Country, Cluster-Randomized Study

Abstract

Currently, no nationally implementable survey exists to identify the burden of hand and upper extremity conditions at the household level in low-middle income countries (LMICs). This study describes a randomized cluster survey approach to estimating the burden of hand and upper extremity conditions in four LMICs using the Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey. Additionally, this study identifies factors associated with responses of unmet surgical need at the multinational level. The SOSAS instrument is a cluster-randomized, cross-sectional, countrywide survey of households administered in Nepal, Rwanda, Sierra Leone, and Uganda from 2011 to 2014. We identified nationwide trends for sociodemographic, anatomic, condition type, mechanism, prevalence, subjective disability, and barriers to care for upper extremity survey responses. A multivariable model identified factors associated with unmet upper extremity need across the four nations. Across the four countries, 13,763 individuals participated in the survey, with 883 conditions of the upper extremity identified (7.4% of all surgical conditions surveyed). Fractures accompanied many of the injuries (32.3%). Although most conditions were acquired, congenital conditions comprised 11% of all etiologies. Overall, open fire/explosion was the most common mechanism (22.9%). Rwandans had the highest proportion of individuals seeking care (91.0%) and receiving care (88.6%). Sierra Leone indicated the fewest seeking and receiving care (71% and 63%, respectively). Chronic injuries were significantly associated with receiving care, whereas illiteracy and worsening subjective disability were barriers to receiving care. In this survey of upper extremity conditions from four LMICs, upper extremity conditions primarily resulted from fire/explosions, and many reported sustaining a fracture. Illiteracy and more disabling conditions decreased the odds of receiving care by 30% to 40%, respectively. The SOSAS survey may provide a reproducible means to evaluate the unmet need for upper extremity care across similar LMICs.
