When patients call their surgeon's office: an opportunity to improve the quality of surgical care and prevent readmissions.

BACKGROUND: Little is known about care coordination and communication with outpatient endocrine surgery patients. This study evaluated phone calls between office nurses and surgical patients to identify common issues addressed and their effect on patient care. METHODS: Qualitative analysis of preoperative and postoperative phone conversations between office nurses and endocrine surgery patients. RESULTS: We identified 183 thyroidectomy patients with 38% contacting our office before surgery and 54% within 30 days after surgery. Common reasons for preoperative calls included questions about preoperative evaluation (21%), medications (18%), and insurance and/or work paperwork (12%). Postoperatively, common topics included medications (23%), laboratory results (23%), and concerns about wounds (12%). Nursing staff prevented unnecessary readmission in 7 patients (4%) whereas appropriately referring 16 (9%) for early evaluation. CONCLUSIONS: Patients frequently contact their surgeons before and after endocrine surgery cases. Our findings suggest several areas for improving communication with patients.

Preventing postoperative hypocalcemia in patients with Graves disease: a prospective study.

BACKGROUND: Hypocalcemia occurs after total thyroidectomy (TT) for Graves disease via parathyroid injury and/or from increased bone turnover. Current management is to supplement calcium after surgery. This study evaluates the impact of preoperative calcium supplementation on hypocalcemia after Graves TT. METHODS: A prospective study of patients with Graves disease undergoing TT was performed. Patients with Graves disease managed over a 9-month period took 1 g of calcium carbonate (CC) three times a day for 2 weeks before TT. Those managed the previous year without supplementation served as historic controls. Age-, gender-, and thyroid weight-matched, non-Graves TT patients were procedure controls. Patient demographics, postoperative laboratory values, complaints, and medications were reviewed. Parathyroid hormone (PTH)-based postoperative protocols dictated postoperative CC and calcitriol use. RESULTS: Forty-five patients with Graves disease were treated with CC before TT, and 38 patients with Graves disease were not. Forty control subjects without Graves disease were identified. Age, gender, and thyroid weight were comparable. Preoperative calcium and PTH levels were equivalent. PTH values immediately after surgery, at postoperative day 1, and at 2-week follow-up were equivalent. Postoperative use of scheduled CC (p = 0.10) and calcitriol (p = 0.60) was similar. Postoperatively, patients with untreated Graves disease had lower serum calcium levels than pretreated patients with Graves disease or control subjects without Graves disease (8.3 mg/dL vs. 8.6 vs. 8.6, p = 0.05). Complaints of numbness and tingling were more common in nontreated Graves disease (26%) than in pretreated Graves disease (9%) or in control subjects without Graves disease (10%, p < 0.05). CONCLUSIONS: Calcium supplementation before TT for Graves disease significantly reduced biochemical and symptomatic postoperative hypocalcemia. Preoperative calcium supplementation is a simple treatment that can reduce symptoms of hypocalcemia after Graves TT.

Surgeon and staff radiation exposure during radioguided parathyroidectomy at a high-volume institution.

INTRODUCTION: Radioguided parathyroidectomy (RGP) uses technetium-99 m sestamibi causing gamma ray emission during RGP to aid dissection and confirm parathyroid excision. Source (the patient) proximity and exposure duration determine degree of exposure. The purpose of this study was to quantify surgeon and staff radiation exposure during RGP. METHODS: Surgeons and assistants wore radiation dosimeters during RGP procedures at a high-volume endocrine surgery practice. Area dosimeters measured personnel potential exposure. Data were prospectively collected. Provider exposures were corrected for both duration of exposure and case volume. Institutional safety requirements uses 100 mrem/year as an indicator for radiation safety training, 500 mrem/year for personal monitoring, and a maximum allowed exposure of 4,500 mrem/year. RESULTS: A total of 120 RGP were performed over 6 months. Badges were worn in 82 cases (68 %). Three faculty and four assistants were included. Primary hyperparathyroidism was the diagnosis for 95 %. Median case volume per provider was 13 cases (range 6-45), with median exposure of 18 h (range 9-70). Mean provider deep dose exposure (DDE) was 22 ± 10 mrem. Corrected for exposure duration, mean DDE was 0.6 ± 0.2 mrem/h. Corrected for case volume, mean DDE was 0.8 ± 0.2 mrem/case. Anesthesia exposure was minimal, while mayo stand exposure was half to two thirds that of the surgeon and assistant. Based on institutional guidelines and above data, 125 RGP/year warrants safety training, 625 RGP/year warrants monitoring, whereas >5,600 RGP/year may result in maximum allowed radiation exposure to the surgeon. CONCLUSIONS: Surgeon and staff radiation exposure during RGP is minimal. However, high-volume centers warrant safety training.

A multi-institutional international study of risk factors for hematoma after thyroidectomy.

BACKGROUND: Cervical hematoma can be a potentially fatal complication after thyroidectomy, but its risk factors and timing remain poorly understood. METHODS: We conducted a retrospective, case-control study identifying 207 patients from 15 institutions in 3 countries who developed a hematoma requiring return to the operating room (OR) after thyroidectomy. RESULTS: Forty-seven percent of hematoma patients returned to the OR within 6 hours and 79% within 24 hours of their thyroidectomy. On univariate analysis, hematoma patients were older, more likely to be male, smokers, on active antiplatelet/anticoagulation medications, have Graves' disease, a bilateral thyroidectomy, a drain placed, a concurrent parathyroidectomy, and benign pathology. Hematoma patients also had more blood loss, larger thyroids, lower temperatures, and higher blood pressures postoperatively. On multivariate analysis, independent associations with hematoma were use of a drain (odds ratio, 2.79), Graves' disease (odds ratio, 2.43), benign pathology (odds ratio, 2.22), antiplatelet/anticoagulation medications (odds ratio, 2.12), use of a hemostatic agent (odds ratio, 1.97), and increased thyroid mass (odds ratio, 1.01). CONCLUSION: A significant number of patients with a postoperative hematoma present >6 hours after thyroidectomy. Hematoma is associated with patients who have a drain or hemostatic agent, have Graves' disease, are actively using antiplatelet/anticoagulation medications or have large thyroids. Surgeons should consider these factors when individualizing patient disposition after thyroidectomy.
