Health seeking behavior of snakebite victims in Sri Lanka: findings from an island-wide community-based study

Abstract

INTRODUCTION AND OBJECTIVES: Health seeking behaviour of snakebite victims in the community has rarely been described and we investigated this as part of a community-based island-wide study on snakebite in Sri Lanka. METHODS: The national snakebite study was conducted in a!! 25 districts, in SriJ_anka in 2012/2013. 44,136 households were sampled in randomly selected clusters. In these households, any member reported to have experienced a snake bite within the preceding 12 months was considered a case. Data related to the health seeking behavior of snakebite were obtained using an interviewer-administered questionnaire. RESULTS: Among 165,665 individuals surveyed, 695 (60% males; median age 43 years) snakebite victims were identified. 323 (46.5%) had evidence of envenoming. 682 (98.2%) had sought health services after the bite. 381 (54.8%) sought allopathic medicine and 99.7% of them obtained this service from the state health sector, while 43.3% sought alternative medicine. The lowest rates of seeking allopathic medicine were seen in the Kalutara (8.7%) and Kegalie (10.7%) districts while highest rates were seen in the districts Mannar, Mullativu and Kilinochchi (100%). Puttalam (92.9%), Vavuniya (92.3%},) Ampara (89.5%), Jaffna (88.9%) and Anuradhapura (86.0%) also had high rates. 70.1% of the victims with envenoming sought allopathic medicine. Victims who had envenoming were significantly more likely to seek allopathic medicine (OR=3.35; 95% confidence interval 2.44-4.59) than those without envenoming. CONCLUSIONS: A considerable proportion of snake bite victims still seek alternative medicines in Sri Lanka.'A wide variation of practices exists across the country. Victims with envenoming are more likely to seek allopathic medicine.
