Background: Thyroid surgery is becoming more common in the elderly as elderly population continues to grow. We aim to evaluate the relative risk of morbidity from thyroidectomy in patients greater than 75 y of age.
Methods: A retrospective analysis was performed for patients who were undergoing thyroidectomy between 2001 and 2018 in a multihospital network. A matched control group was selected with use of a propensity score, which was based on gender, ethnicity, type of surgery, insurance status, and comorbidities. The Charlson Comorbidity Index was used to quantify comorbidities. Total complications included both thyroid-specific and systemic complications.
Results: We identified 313 patients over the age of 75 y with a propensity score matched group of 313 patients. There was no difference between the percent female (73% versus 73%, P = 0.92), race composition (P = 0.91), insurance status (P = 0.99), percent undergoing total thyroidectomy (84% versus 84%, P = 0.91), and Charlson Index (2.6 versus 2.69, P = 0.70) of the two groups. Overall complications (4.8% versus 1.9%, P = 0.05) and thrombotic events (1.2 versus 0%, P = 0.04) were significantly higher but there was no statistically significant difference between postoperative emergency room visits (7% versus 6%, P = 0.61), readmissions (11.5% versus 8.6%, P = 0.18), cardiovascular (1.3 versus 0.6%, P = 0.61), pulmonary (3.2 versus 0.9%, P = 0.07), or neurologic complications (1.0 versus 0.3%, P = 0.34). No reoperations were noted in either group. Elder patients did have a longer length of stay (2.64 versus 1.29 d, P < 0.01).
Conclusions: Elderly patients did have a longer length of stay when compared to a matched younger population. Although there was a trend with higher complication rates in the elderly, those differences did not reach statistical significance.
