Clinico-epidemiological Profile of Frostbite Cases in High Altitude Region of Northern India

Abstract Objectives: The objective of the study was to study the clinico-epidemiological profile of frostbite cases in high altitude region of Northern India. Study Design: This study involves a descriptive study. Materials and Methods: A descriptive study was undertaken in service hospitals situated in the northernmost region of India receiving frostbite cases from December 1, 2019, to Mar 30, 2020, to assess their clinico-epidemiological profile. A semi-structured questionnaire was designed comprising demographic characteristics and clinical and epidemiological characteristics of the frostbite cases. Frostbite cases were classified based on grades of injury and were studied for any association with age, physical activity, and temperature extremes. Results: A total of 29 cases of frostbite were reported during the study period with the majority of cases being <25 years of age. All cases were reported at altitudes of above 12,000 ft. and maximum cases gave a history of direct exposure to extreme weather conditions or other predisposing factors. The most common complaint at the onset of the symptoms was discoloration of the skin followed by swelling of digits and pain with most of the cases falling under first and second grade of injury. Protective clothing and footwear were adequate during induction/de-induction/stay in extreme climate regions. Conclusions: Exposure to extreme cold climates, high altitude, personal clothing, and physical exertion plays an essential role in the occurrence of frostbite cases as well as their severity. With the rising number of cases of frostbite, understanding of multiple factors which predisposes to frostbite injury is essential.
