Impact of COVID-19 pandemia on spine surgery in 2nd level hospital. / Impacto de la pandemia COVID-19 en la cirugía de columna en un centro de segundo nivel.

INTRODUCTION: The consequences of COVID-19 pandemic, like in any other field of medicine, had such a massive effect in the activity of spine surgeons. OBJECTIVES: The main purpose of the study is quantifying the number of interventions done between 2016 and 2021 and analyze the time between the indication and the intervention as an indirect measurement of the waiting list. As secondary objectives we focused on variations of the length of stay and duration of the surgeries during this specific period. METHODS: We performed a descriptive retrospective study including all the interventions and diagnosis made during a period including pre-pandemic data (starting on 2016) until 2021, when we considered the normalization of surgical activity was achieved. A total of 1039 registers were compiled. The data collected included age, gender, days in waiting list before the intervention, diagnosis, time of hospitalization and surgery duration. RESULTS: We found that the total number of interventions during the pandemic has significantly decreased compared to 2019 (32.15% less in 2020 and 23.5% less in 2021). After data analysis, we found an increase of data dispersion, average waiting list time and for diagnosis after 2020. No differences were found regarding hospitalization time or surgical time. CONCLUSION: The number of surgeries decreased during pandemic due to the redistribution of human and material resources to face the raising of critical COVID-19 patients. The increase of data dispersion and median of waiting time, is the consequence of a growing waiting list for non-urgent surgeries during the pandemic as the urgent interventions also raised, those with a shorter waiting time.
