Medical Injection Use Among Adults and Adolescents Aged 15 to 64 Years in Kenya

Abstract

Unsafe medical injections remain a potential route of HIV transmission in Kenya. We used data from a national survey in Kenya to study the magnitude of medical injection use, medication preference, and disposal of medical waste in the community. The Kenya AIDS Indicator Survey 2012 was a nationally representative population-based survey. Among participants aged 15-64 years, data were collected regarding medical injections received in the year preceding the interview; blood samples were collected from participants for HIV testing. Of the 13,673 participants who answered questions on medical injections, 35.9% [95% confidence interval (CI): 34.5 to 37.3] reported receiving ≥1 injection in the past 12 months and 51.2% (95% CI: 49.7 to 52.8) preferred receiving an injection over a pill. Among those who received an injection from a health care provider, 95.9% (95% CI: 95.2 to 96.7) observed him/her open a new injection pack, and 7.4% (95% CI: 6.4 to 8.4) had seen a used syringe or needle near their home or community in the past 12 months. Men who had received ≥1 injection in the past 12 months (adjusted odds ratio, 3.2; 95% CI: 1.2 to 8.9) and women who had received an injection in the past 12 months, not for family planning purposes (adjusted odds ratio, 2.6; 95% CI: 1.2 to 5.5), were significantly more likely to be HIV infected compared with those who had not received medical injection in the past 12 months. Injection preference may contribute to high rates of injections in Kenya. Exposure to unsafe medical waste in the community poses risks for injury and infection. We recommend that community- and facility-based injection safety strategies be integrated in disease prevention programs.
