To admit or not to admit? Experience with outpatient thyroidectomy for Graves' disease in a high-volume tertiary care center

Does Graves' Disease Truly Increase the Risk of Complications After Total Thyroidectomy?

INTRODUCTION

Total thyroidectomy (TTx) has been reported to be more challenging in patients with Graves' disease, especially in those who are hyperthyroid at the time of surgery. Our aim was to compare outcomes in patients undergoing TTx for Graves' disease compared to other thyroid diseases at a large academic institution with high-volume fellowship-trained endocrine surgeons.

METHODS

In our retrospective analysis from December 2015 to May 2023, patients undergoing TTx for Graves' disease were compared to those undergoing TTx for all other indications excluding advanced malignancy (poorly differentiated thyroid cancer and concomitant neck dissections). Patient demographics, biochemical values, and postoperative outcomes were compared. A subgroup analysis was performed comparing hyperthyroid to euthyroid patients at the time of surgery.

RESULTS

There were 589 patients who underwent TTx, of which 227 (38.5%) had Graves' disease compared to 362 (61.5%) without. Intraoperatively in Graves' patients, nerve monitoring was used more frequently (65.6% versus 57.1%; P = 0.04) and there was a higher rate of parathyroid autotransplantation (32.0% versus 14.4%; P < 0.01). Postoperatively, transient voice hoarseness occurred less frequently (4.8% versus 13.6%; P < 0.01) and there was no difference in temporary hypocalcemia rates or hematoma rates. In our subgroup analysis, 83 (36%) of Graves' patients were hyperthyroid (thyroid-stimulating hormone < 0.45 and free T4 > 1.64) at the time of surgery and there were no differences in postoperative complications compared to those who were euthyroid.

CONCLUSIONS

At a high-volume endocrine surgery center, TTx for Graves' disease can be performed safely without significant differences in postoperative outcomes. Hyperthyroid patients demonstrated no differences in postoperative outcomes.

Complications related to thyroidectomy among patients with hyperthyroidism: Exploring the potential for ambulatory surgery

BACKGROUND

Total thyroidectomy for hyperthyroidism is typically followed by overnight admission to monitor for complications including thyrotoxicosis. Outpatient thyroid surgery is increasingly common, but its safety in patients with hyperthyroidism has not been well studied.

METHODS

This retrospective study reviewed 183 patients with hyperthyroidism who underwent total thyroidectomy from 2015 to 2022 at one urban, academic center. The main outcomes were rates of thyroid storm, surgical complications, and 30-day ED visits and readmissions.

RESULTS

Among 183 patients with hyperthyroidism (mean age, 45 ± 14.5 years; 82.5% female), there were no cases of thyroid storm and complications included recurrent laryngeal nerve (RLN) palsy (7.0%), symptomatic hypocalcemia (4.4%), and hematoma (1.6%). ED visits were present in 1.1% and no patients were readmitted.

CONCLUSION

Total thyroidectomy was not associated with thyroid storm and <6% of patients required inpatient management. Ambulatory total thyroidectomy for hyperthyroidism warrants further consideration through identification of predictive factors for postoperative complications.

Incidental but Not Insignificant: Thyroid Cancer in Patients with Graves Disease

BACKGROUND

Graves disease is the most common cause of hyperthyroidism in the US. Treatment with antithyroid drugs and radioactive iodine is more commonly used than surgical management with total thyroidectomy (TTx). However, incidentally discovered thyroid cancer (TC) has been described on surgical pathology from patients who underwent surgical treatment of Graves disease, which would be missed with these other treatment strategies. We sought to determine the incidence rate of TC among patients with surgically treated Graves disease.

STUDY DESIGN

We retrospectively reviewed patients with Graves disease who underwent TTx at a single institution from 2011 to 2023. Pathology reports were reviewed for TC. Patient demographics, preoperative laboratory and radiological evaluations, preoperative medical management, and surgical outcomes were compared between patients with and without incidental TC.

RESULTS

There were 934 patients, of whom 60 (6.4%) patients had incidentally discovered TC on pathology. The majority (58.3%) of patients had papillary thyroid carcinoma, followed by 33.3% with papillary microcarcinoma. Preoperative ultrasound (US) was obtained in 564 (60.4%) of patients, with 44.3% with nodules, but only 34 (13.7%) of those with nodules had TC on final pathology. Preoperative fine needle aspiration was obtained in 15 patients with TC, and 8 patients (53.3%) were reported as benign lesions, which ultimately had TC on final pathology. There was no difference in sex, race or ethnicity, preoperative medical management, and postoperative outcomes between the 2 groups.

CONCLUSIONS

Incidental TC was found on surgical pathology in 6.4% of patients undergoing TTx for Graves disease. Preoperative imaging with US and fine needle aspiration were often unreliable at predicting TC. The incidence of TC should not be underestimated when counseling patients on definitive management for Graves disease.

Clinical outcomes of outpatient thyroidectomy: A systematic review and single-arm meta-analysis

BACKGROUND

The aim of this meta-analysis is to investigate the safety of outpatient thyroidectomy based on 24-h and same-day discharge criteria.

METHODS

CENTRAL, Embase, PubMed, and Scopus were searched. A meta-analysis of selected studies was performed. The review was registered prospectively with PROSPERO (CRD42022361134).

RESULTS

Thirty-one studies met the eligibility criteria, with a total of 74328 patients undergoing thyroidectomy in an outpatient setting based on 24-h discharge criteria. Overall postoperative complications after outpatient thyroidectomies were 5.7% (95%CI: 0.049-0.065; I2 ​= ​97.3%), consisting of hematoma (0.4%; 95%CI: 0.003-0.005; I2 ​= ​83.4%), recurrent laryngeal nerve injury (0.4%; 95%CI: 0.003-0.006; I2 ​= ​93.5%), and hypocalcemia (1.6%; 95%CI: 0.012-0.019; I2 ​= ​93.7%). The rate of readmission was 1.1% (95%CI: 0.007-0.015; I2 ​= ​95.4%). Results were similar for same-day criteria.

CONCLUSIONS

Our analysis demonstrated that outpatient thyroidectomy is a safe procedure in the management of thyroid disease for selected patients.

Emergency department use after outpatient thyroidectomy across three states

BACKGROUND

Although outpatient thyroidectomy has become common, few large-scale studies have examined post-thyroidectomy emergency department use, readmission, and encounters not resulting in readmission, known as "treat-and-release" encounters. We evaluated post-outpatient thyroidectomy emergency department use and readmission and characterized associated factors.

METHODS

Using the Healthcare Cost and Utilization Project databases, we identified adult outpatient (same-day or <24-hour discharge) thyroidectomies performed in Florida, Maryland, and New York from 2016 to 2017. We identified the procedures linked with emergency department treat-and-release encounters and readmissions within 30 days postoperatively and the factors associated with post-thyroidectomy emergency department use and readmission.

RESULTS

Of the 17,046 patients who underwent outpatient thyroidectomy at 374 facilities, 7.5% had emergency department treat-and-release encounters and 2.3% readmissions. The most common reasons for emergency department treat-and-release encounters (9.9%) and readmissions (22.2%) were hypocalcemia-related diagnoses. Greater odds of treat-and-release were associated with identifying as non-Hispanic Black (adjusted odds ratio: 1.5, 95% confidence interval: 1.3-1.8) or Hispanic race/ethnicity (adjusted odds ratio: 1.4, 95% CI: 1.1-1.6), having Medicaid insurance (adjusted odds ratio: 2.7, 95% CI: 2.3-3.2), and living in non-metropolitan areas (adjusted odds ratio: 1.6, 95% CI: 1.1-2.2). We observed no associations between these factors and the odds of readmission.

CONCLUSION

Emergency department use after outpatient thyroidectomy is common. Racial, ethnic, socioeconomic, and geographic disparities are associated with treat-and-release encounters but not readmissions. Standardization of perioperative care pathways, focusing on identifying and addressing specific issues in vulnerable populations, could improve care, reduce disparities, and improve patient experience by avoiding unnecessary emergency department visits after outpatient thyroidectomy.

Physician-Targeted Interventions Reduce Surgical Expense and Improve Value-Driven Health Outcomes

INTRODUCTION

Increasing health-care costs in the United States have not translated to superior outcomes in comparison to other developed countries. The implementation of physician-targeted interventions to reduce costs may improve value-driven health outcomes. This study aimed to evaluate the effectiveness of physician-targeted interventions to reduce surgical expenses and improve care for patients undergoing total thyroidectomies.

METHODS

Two separate face-to-face interventions with individual surgeons focusing on surgical expenses associated with thyroidectomy were implemented in two surgical services (endocrine surgery and otolaryngology) by the surgical chair of each service in Jun 2016. The preintervention period was from Dec 2014 to Jun 2016 (19 mo, 352 operations). The postintervention period was from July 2016 to January 2018 (19 mo, 360 operations). Descriptive statistics were utilized, and differences-in-differences were conducted to compare the pre and postintervention outcomes including cost metrics (total costs, fixed costs, and variable costs per thyroidectomy) and clinical outcomes (30-d readmission rate, days to readmission, and total length of stay).

RESULTS

Patient demographics and characteristics were comparable across pre- and post-intervention periods. Post-intervention, both costs and clinical outcomes demonstrated improvement or stability. Compared to otolaryngology, endocrine surgery achieved additional savings per surgery post-intervention: mean total costs by $607.84 (SD: 9.76; P < 0.0001), mean fixed costs by $220.21 (SD: 5.64; P < 0.0001), and mean variable costs by $387.82 (SD: 4.75; P < 0.0001).

CONCLUSIONS

Physician-targeted interventions can be an effective tool for reducing cost and improving health outcomes. The effectiveness of interventions may differ based on specialty training. Future implementations should standardize these interventions for a critical evaluation of their impact on hospital costs and patient outcomes.

Outpatient compared to inpatient thyroidectomy on 30-day postoperative outcomes: a national propensity matched analysis

BACKGROUND

To address the postoperative outcomes between outpatient and inpatient neck surgery involving thyroidectomy procedures.

METHODS

A cohort analysis of surgical patients undergoing primary, elective, total thyroidectomy from multiple United States medical institutions who were registered with the American College of Surgeons National Surgical Quality Improvement Program from 2015 to 2018. The primary outcome was a composite score that included any 30-day postoperative adverse event.

RESULTS

A total of 55,381 patients who underwent a total thyroidectomy were identified comprising of 14,055 inpatient and 41,326 outpatient procedures. A cohort of 13,496 patients who underwent outpatient surgery were propensity matched for covariates with corresponding number of patients who underwent inpatient thyroidectomies. In the propensity matched cohort, the occurrence of any 30-day after surgery complications were greater in the inpatient group, 424 out of 13,496 (3.1%) compared to the outpatient group, 150 out of 13,496 (1.1%), P < 0.001. Moreover, death rates were greater in the inpatient group, 22 out 13,496 (0.16%) compared to the outpatient group, 2 out of 13,496 (0.01%), P < 0.001. Similarly, hospital readmissions occurred with greater frequency in the inpatient group, 438 out of 13,496 (3.2%) compared to the outpatient group, 310 out of 13,496 (2.3%), P < 0.001.

CONCLUSION

Thyroidectomy procedures performed in the outpatient setting had less rates of adverse events, including serious postoperative complications (e.g., surgical site infection, pneumonia, progressive renal insufficiency). In addition, patients who had thyroidectomy in the outpatient setting had less 30-day readmissions and mortality. Surgeons should recognize the benefits of outpatient thyroidectomy when selecting disposition of patients undergoing neck surgery.

The safety, benefits and future development of overnight and outpatient thyroidectomy

With the development of medical care, the safety of thyroidectomy is improving year by year. Due to economic benefits and other advantages of the overnight and outpatient thyroidectomy, more and more patients and medical institutions have favored overnight and outpatient thyroidectomy, and its proportion in thyroidectomy has increased year by year. However, overnight and outpatient thyroidectomy still faces many challenges and remains to be improved. In this review, we focused on the recent progress and the relevant clinical features of overnight and outpatient thyroidectomy, including its safety, economic benefits, etc., which may bring valuable clues and information for further improvements of patient benefits and promotions of overnight or outpatient thyroidectomy in the future.

Time to Symptom Resolution After Total Thyroidectomy for Graves' Disease

INTRODUCTION

Total thyroidectomy (TT) has been shown to be a safe and effective treatment for Graves' disease. However, the time course for improvement of symptoms has not been defined.

METHODS

With an institutional review board approval, we prospectively gathered survey data of all patients (n = 79) undergoing TT for Graves' disease at a single institution from 2019 to 2021. After informed consent was obtained, patients completed surveys preoperatively and at 2 wk followed by monthly postoperative visits/phone calls. Patient demographics and survey results were collected and analyzed. Symptom recovery time was evaluated using Kaplan-Meier analysis.

RESULTS

A total of 50 patients completed the survey on postoperative follow-up (response rate 63%). Average age was 38 y (range 12-80 y) and 88% of patients were female. The most common preoperative symptoms were fatigue (90%) and heat/cold intolerance (88%). Tremor (median time to resolution: 1 wk; interquartile range [IQR] 1-3), diarrhea (median 1 wk [IQR 1-3]), and palpitations (median 1 wk [IQR 1-3]) resolved the most rapidly followed by eye symptoms (median 3 wk [IQR 1-6]), heat/cold intolerance (median 3 wk [IQR 3-30]), memory deficits (median 3 wk [IQR 1-undefined]), and fatigue (median: 3 wk [IQR 1-14]). There were no significant differences in time to resolution of symptoms by gender or age (less than versus 40 y and older). Those with uncontrolled Graves' had more severe symptoms but no difference in time to resolution from the euthyroid Graves' patients.

CONCLUSIONS

Many Graves' disease symptoms improve rapidly following TT, with a median time to improvement of less than 1 mo.

Ambulatory Surgery vs Overnight Observation for Total Thyroidectomy: Cost Analysis and Outcomes

Objective

To compare financial impact between patients undergoing ambulatory (same-day discharge) vs overnight admission after total thyroidectomy while showing associated surgical outcomes.

Study Design

Retrospective review.

Setting

University of Alabama at Birmingham Medical Center from October 2011 and July 2017.

Methods

Patients undergoing total thyroidectomy without concurrent procedures were selected for review. Demographics, comorbidities, admission status, postoperative outcomes including minor and major complications, charges, and costs were collected. Admission status was categorized as inpatient (admission to hospital ≥1 night) or outpatient (discharged from the postoperative recovery unit). Costs were obtained from all related hospital, clinic, and emergency department visits at the University of Alabama at Birmingham within 30 days of the original surgery. After statistical analysis, outcomes and costs were compared between inpatient and outpatient total thyroidectomy patients.

Results

Of 870 total thyroidectomy patients included for analysis, 367 (42.2%) met outpatient criteria. A total of 169 patients (19.4%) had a complication, and only hypocalcemia occurred significantly more in the inpatient group (14.3% vs 9.26%; P < .05). No complications occurred more frequently in the outpatient population. There were no mortalities. There was a statistically significant difference between the total cost of inpatient and outpatient thyroidectomies, with outpatient surgery costing on average $2367.27 less per patient (P < .0001).

Conclusion

Outpatient total thyroidectomy can lead to cost reduction in highly selected patients who have few comorbidities while remaining safe for the patient.

Intraoperative parathyroid hormone measurement facilitates outpatient thyroidectomy in children

INTRODUCTION

We hypothesize that intraoperative parathyroid hormone (ioPTH) measurement after a total thyroidectomy predicts children at risk for hypoparathyroidism and allow for outpatient procedure.

METHODS

Between 2015 and 2019, we reviewed all patients under the age of 21 undergoing a thyroidectomy (total or lobectomy). Based on the ioPTH concentration, the patients were treated by the following protocol: a) PTH ≥20 pg/mL: no treatment; b) PTH = 10-19 pg/mL: 1000 mg calcium orally TID; c) PTH = 5-9 pg/mL: calcitriol 250 μg orally BID plus 1000 mg calcium orally TID; or d) PTH <5 pg/mL calcitriol 500 μg orally BID plus 1000 mg calcium orally TID.

RESULTS

Fifty-two patients were included with a median age of 16 (range 6-21 years). Thirty-two patients (62%) had normal PTH (≥10 pg/mL) while 20 (38%) had low PTH levels (<10 pg/mL). Of those patients with low PTH, 60% had normalization of levels within 2 weeks of surgery.

CONCLUSIONS

Thyroid surgery in children can be performed as an outpatient procedure. The ioPTH measurements and a protocol to treat patients with low PTH assists in safe discharge.

Considerations for Thyroidectomy as Treatment for Graves Disease

Hyperthyroidism is a clinical state that results from abnormally elevated thyroid hormones. Thyroid gland affects many organ systems; therefore, patients usually present with multiple clinical manifestations that involve many organ systems such as the nervous, cardiovascular, muscular, and endocrine system as well as skin manifestations. Hyperthyroidism is most commonly caused by Graves disease, which is caused by autoantibodies to the thyrotropin receptor (TRAb). Other causes of hyperthyroidism include toxic multinodular goiter, toxic single adenoma, and thyroiditis. Diagnosis of hyperthyroidism can be established by measurement of thyroid-stimulating hormone (TSH), which will be suppressed with either elevated free T4 and/or T3 (overt hyperthyroidism) or normal free T3 and T4 (subclinical hyperthyroidism). Hyperthyroidism can be treated with antithyroid drugs (ATDs), radioactive iodine (RAI), or thyroidectomy. ATDs have a higher replacement rate when compared with RAI or thyroidectomy. Recent evidence has shown that thyroidectomy is a very effective, safe treatment modality for hyperthyroidism and can be performed as an outpatient procedure. This review article provides some of the most recent evidence on diagnosing and treating patients with hyperthyroidism.
