The objective was to determine the pattern of health service utilization by the injured in Kumasi, Ghana and thus to gain information useful for the strengthening of trauma care in that environment. A household survey was utilized as it was anticipated that many injured might not receive formal medical care and a total of 11,663 persons living in 264 clusters in Kumasi were surveyed. One-third of all injured did not receive any formal medical care, mainly due to financial constraints. Altogether, 37% of the injured attended a hospital and 34% attended a clinic. Among the severely injured (> or =1 month disability) attending a clinic, most (76%) used it as the sole source of care. Most (54%) of these clinics were private. Efforts to strengthen trauma care in urban Africa need to address financial barriers to care and need to consider clinics, as well as the main hospitals.
