Abstract
ObjectivesTreatment for primary hyperparathyroidism is parathyroidectomy. This study identifies the association between hypoalbuminemia (HA) and outcomes in patients undergoing parathyroidectomy for primary hyperparathyroidism.MethodsThis retrospective cohort analysis utilized the 2006–2015 National Surgical Quality Improvement Program database. Current Procedure Terminology codes were used to identify patients undergoing parathyroidectomy for primary hyperparathyroidism. Prolonged length of stay (LOS) was defined as a duration of 2 days or greater. Demographics and comorbidities were compared between HA (serum albumin <3.5 g/dL) and non‐HA cohorts using chi‐square analysis. The independent effect of HA on adverse outcomes was analyzed using binary logistic regression.ResultsA total of 7183 cases with primary hyperparathyroidism were classified into HA (n = 381) and non‐HA (n = 6802) cohorts. HA patients had increased complications, including renal insufficiency (0.8% vs. 0.0%, p = 0.001), sepsis (1.0% vs. 0.1%, p = 0.003), pneumonia (0.8% vs. 0.1%, p = 0.018), acute renal failure (1.0% vs. 0.0%, p < 0.001), and unplanned intubation (1.3% vs. 0.2%, p = 0.004). HA patients had increased risk of death (1.6% vs. 0.1%, p < 0.001), prolonged LOS (40.9% vs. 6.3%, p < 0.001), and any complication (5.5% vs. 1.2%, p < 0.001). Adjusted binary logistic regression indicated HA patients experienced increased odds of progressive renal insufficiency (OR 18.396, 95% CI 1.844–183.571, p = 0.013), prolonged LOS (OR 4.892; 95% CI 3.571–6.703; p < 0.001), unplanned reoperation (OR 2.472; 95% CI 1.012–6.035; p = 0.047), and unplanned readmission (OR 3.541; 95% CI 1.858–6.748; p < 0.001).ConclusionsHA may be associated with adverse complications in patients undergoing parathyroidectomy for primary hyperparathyroidism.Level of Evidence3 Laryngoscope, 133:2035–2039, 2023
