Epidemiological study of chronic dermal ulcers in China.
A total of 30,000 hospitalized surgical patients in 15 hospitals were screened for chronic ulcers. A total of 489 patients with chronic dermal ulcers were found with their major causes of ulceration including traumatic wounds, infections, diabetes mellitus, and venous diseases. Patients with chronic ulcers following trauma and infection comprised 67.48% of the total patient population. The incidence of diabetic ulcers and venous ulcers was 4.91% and 6.54% respectively. Sites of ulceration differed with different etiological factors. The percentage of chronic dermal ulcers in the lower extremities, upper extremities, thorax and abdomen, back, and head was 63.10%, 17.93%, 7.76%, 4.83% and 6.38% respectively. Of the 489 patients with chronic ulcers, 183 were farmers (37.42%), and 131 were workers (26.79%). Chronic dermal ulcers were more common in men than in women, but there was no significant difference in the sex-related prevalence. According to these data from different hospitals, the incidence of chronic ulcers in patients hospitalized for surgery was 1.5% to 3.0%. These data have primarily shown the prevalence and clinical characteristics of chronic ulcers in hospitalized patients in China. These data may not be consistent with reports from other countries. Significant differences in etiological factors of ulceration, professional distribution of patients with chronic dermal ulcers, and treatment methods were found when compared with reports of studies conducted in developed countries. Our results will benefit not only additional basic research, but these data will also be useful in preventing and managing chronic wounds in developing countries.
