Objective:
“The aim of this retrospective cohort study was to study the impact of age on in-hospital complications and mortality following surgery for Ankylosing Spondylitis (AS) associated spine fractures.”
Methods:
“We extracted data from the Nationwide Inpatient Sample (NIS) database (1998–2018) using ICD-9/10 codes. Patients with a primary diagnosis of AS associated spine fractures who underwent fusion surgery were included. Complications and in-hospital mortality were analyzed.”
Results:
“A total cohort of 8526 patients was identified. Overall, the median age of the cohort was 69 years. AS associated fractures were equally distributed among cervical and thoracolumbar regions.
Overall, complications were noted in 48% of patients and pulmonary complications were the most common (32%) followed by renal (13%) and infection (12%).
Complications were seen in 57.3% of patients ≥ 70 years of age compared to 38.4% of patients < 70 years of age (p < .0001). Also, 9.9 % of patients ≥ 70 years of age had in-hospital mortality compared to 3.1 % of patients < 70 years of age (p < .0001).
Based on surgical approaches, elderly patients (≥70 years) who underwent anterior, posterior, and anterior + posterior approaches had 19.8%, 7.4% and 16.4% in-hospital mortality compared to 5.3%, 2.2% and 7.4% respectively for patients < 70 years.”
Conclusions:
“Elderly patients (≥70 years of age) were 3.2 times more likely to have in-hospital mortality and higher complications compared to younger patients (57% vs. 38%). Cervical compared to thoracolumbar fractures and anterior compared to posterior surgical approaches were associated with higher complications and in-hospital mortality.”
