Frailty tools assess symptoms and comorbidities that may coincide with those of primary hyperparathyroidism. To test the hypothesis that parathyroidectomy improves frailty, we conducted a prospective cohort comparison of frailty after parathyroid or thyroid surgery.
The Risk Analysis Index measuring frailty was prospectively administered to patients undergoing curative parathyroid exploration or total thyroidectomy. Risk Analysis Index results at the preoperative, postoperative, and last follow-up visits were assessed longitudinally.
Compared to total thyroidectomy patients (n = 142), parathyroid exploration patients (n = 187) were older (P = .001), more often male (P = .05) and had longer surgical follow-up (P < .001). Mean preoperative Risk Analysis Index scores were higher in parathyroid exploration patients (24 ± 9 vs total thyroidectomy 17 ± 8, P < .001). Parathyroid exploration patients demonstrated a significant decrease in Risk Analysis Index score from preoperative to last follow-up (P < .01); total thyroidectomy patients did not (P = .44). Parathyroid exploration patients were also less likely to exhibit a 20% increase in Risk Analysis Index over time, suggesting that parathyroidectomy slowed progression of frailty (2% vs 19%, P = .003).
In this prospective study of frailty using a validated assessment tool, Risk Analysis Index scores decreased after parathyroid exploration surgery. When compared to total thyroidectomy patients, parathyroid exploration patients were also less likely to suffer a clinically meaningful = 20% increase in Risk Analysis Index scores after surgery, suggesting that parathyroid exploration patients better maintained baseline health at final follow-up.
