Epidemiology of electrical burns and its impact on quality of life - the developing world scenario.

Abstract

BACKGROUNDElectrical burns are devastating injuries and can cause deep burns with significant morbidity and delayed sequelae. Epidemiological data regarding the etiology, socioeconomic differences and geographic variation are necessary to assess the disease burden and plan an effective preventive strategy. These severe injuries often lead to amputations and thus hamper quality of life in the long termAIMTo identify the population at maximum risk of sustaining electrical burns. We also studied the impact of electrical burns on these patients in terms of quality of life as well as return to work. METHODSThe study was conducted at a tertiary referral teaching hospital over a period of eighteen months. All patients with a history of sustaining electrical burns and satisfying the inclusion criteria were included in the study. All relevant epidemiological parameters and treatment details were recorded. The patients were subsequently followed up at 3 mo, 6 mo and 9 mo. The standardized Brief Version of the Burn Specific Health Scale (BSHS-B) was adopted to assess quality of life. Statistical analysis was conducted using IBM SPSS statistics (version 22.0). A P value of < 0.05 was considered statistically significant. RESULTSA total of 103 patients were included in the study. The mean age of the patients was 31.83 years (range 18-75 years). A significant majority (91.3%) of patients were male. The mean total body surface area (TBSA) in these patients was 21.1%. In most of the patients (67%), the injury was occupation-related. High voltage injuries were implicated in 72.8% of patients. Among the 75 high voltage burn patients, 31 (41%) required amputation. The mean number of surgeries the patients underwent in hospital was 2.03 (range 1 to 4). The quality of life parameters amongst the patients sustaining high voltage electrical burns were poorer when compared to low voltage injuries at all follow-up intervals across nine domains. In eight of these domains, the difference was statistically significant. Similarly, the scores among the amputees were poorer when compared to non-amputees. The difference was statistically significant in six domains. CONCLUSIONElectrical burns remain a problem in the developing world. Most injuries are occupation-related. The quality of life in patients with high voltage burns and amputees remains poor. Work resumption was almost impossible for amputees. These patients could not regain pre-injury status. Steps should be taken to create awareness and to implement an effective preventive strategy to safeguard against electrical injuries.
