Hospital discharge rate for traumatic foot and/or ankle amputation in Chile: a descriptive epidemiological analysis from 2018 to 2022

Abstract

Introduction: Traumatic amputation of the foot-ankle is a medical emergency with high morbidity and mortality, affecting structures distal to the tibiotalar joint, requiring immediate hospital care and carrying significant implications. The scarcity of Chilean epidemiological data justifies the need for local research. Objective: To describe the rate of hospital admissions for traumatic amputation of the foot and/or ankle in Chile between 2018 and 2022, by sex and age group, in addition to the average hospital stay. Methodology: Quantitative, observational, descriptive, and cross-sectional, using secondary data analysis of hospital discharges due to foot-ankle traumatic amputation in Chile from 2018-2022 (N=543). Hospital discharge rate and average hospital stay were calculated.  Result: The hospital discharge rate was 0,62 per 100.000 inhabitants. The male sex showed a higher hospital discharge rate (1,03) than females (0,22). The 65-79 age group had the highest hospital discharge rate (2,01). General average hospital stay was 11,06 days, longer in males (11,61) compared to females (8,62). Discussion: The hospital discharge rate is lower than in developed countries, possibly due to differences in registration systems or exposure to risk factors. The disparity between sexes suggests greater male exposure to risk activities. The high rate in the 65-79 years age group contrasts with the literature, possibly due to vulnerability associated with aging. Conclusion: This study provides an epidemiological characterization, highlighting the need for preventive strategies in high-risk groups and the importance of current occupational safety measures. Future research is needed on specific etiologies and long-term functional outcomes.
