Outpatient endocrine surgery practice patterns are highly variable among US endocrine surgery fellowship programs

Hsu, Shawn; Melucci, Alexa D; Dave, Yatee A; Chennell, Todd; Fazendin, Jessica; Suh, Insoo; Moalem, Jacob
BACKGROUND:Current studies and guidelines have reported that outpatient endocrine surgery is safe. However, none recommend specific postoperative protocols. METHODS:An internet-based survey, developed using expert input, was distributed to current (2021-2022) endocrine surgery fellows in American Association of Endocrine Surgeons-accredited programs (n = 23). Programs with ≤2% same-day discharge rate were compared with those with ≥2% same-day discharge rate. RESULTS:The survey response rate was 91% (21/23), representing 20 United States institutions performing >15,000 cervical endocrine operations annually. The same-day discharge rate after total thyroidectomy was not normally distributed across institutions (P < .0001) but appeared bimodal, highlighting dogmatic differences in the pursuit of same-day discharge. Nine programs had ≤2% same-day discharge rate, whereas seven had ≥90% same-day discharge rate. Fourteen (70%) reported minimum observation periods before discharge, without consistency across procedures or institutions. Total thyroidectomy patients were observed longer. Fourteen (70%) reported no geographic restrictions for same-day discharge. In programs with >2% same-day discharge (n = 11), clinical and operative factors inconsistently influenced same-day discharge after thyroidectomy. Living alone precluded same-day discharge in 3 programs. Lateral neck dissection and chronic anticoagulation each greatly reduced same-day discharge in one program and precluded same-day discharge in another. Central neck dissection, Graves' disease, substernal goiter, continuous positive airway pressure use, difficult/bloody operation, and signal on nerve stimulation had no or minimal effect on same-day discharge. Postoperative medication recommendations varied among programs. Although anticoagulation/antiplatelet agents were similarly held preoperatively across programs, resumption varied. Narcotics were routinely prescribed in 35%. CONCLUSION/CONCLUSIONS:Same-day discharge is not uniform across endocrine surgery training programs and is likely primarily driven by surgeon preference. Factors influencing same-day discharge vary significantly among programs.

Wright, Kyla; Mahmoudi, Mandana; Agrawal, Nidhi; Simpson, Hope; Lui, Michael S; Pachter, H Leon; Patel, Kepal; Prescott, Jason; Suh, Insoo
BACKGROUND:There is a bidirectional association between primary aldosteronism and obstructive sleep apnea, with evidence suggesting that the treatment of primary aldosteronism can reduce obstructive sleep apnea severity. Current guidelines recommend screening for primary aldosteronism in patients with comorbid hypertension and obstructive sleep apnea, identifying potential candidates for treatment. However, emerging data suggest current screening practices are unsatisfactory. Moreover, data regarding the true incidence of primary aldosteronism among this population are limited. This study aimed to assess the primary aldosteronism screening rate among patients with obstructive sleep apnea and hypertension at our institution and estimate the prevalence of primary aldosteronism among this population. METHODS:Sleep studies conducted at our institution between January and September 2021 were retrospectively reviewed. Adult patients with a sleep study diagnostic of obstructive sleep apnea (respiratory disturbance index ≥5) and a diagnosis of hypertension were included. Patient medical records were reviewed and laboratory data of those with biochemical screening for primary aldosteronism were assessed by an experienced endocrinologist. Screening rates were compared before and after initiation of a screening protocol in accordance with the 2016 Endocrine Society guidelines. RESULTS:A total of 1,005 patients undergoing sleep studies were reviewed; 354 patients had comorbid obstructive sleep apnea and hypertension. Patients were predominantly male (67%), with a mean age of 58 years (standard deviation = 12.9) and mean body mass index of 34 (standard deviation = 8.1). The screening rate for primary aldosteronism among included patients was 19% (n = 67). The screening rate was significantly higher after initiation of a dedicated primary aldosteronism screening protocol (23% vs 12% prior; P = .01). Fourteen screens (21%) were positive for primary aldosteronism, whereas 45 (67%) were negative and 8 (12%) were indeterminate. Four had prior abdominal cross-sectional imaging, with 3 revealing an adrenal adenoma. Compared with patients without primary aldosteronism, patients with positive primary aldosteronism screens were more likely to have a history of hypokalemia (36% vs 4.4%; P = .002). The frequency of hyperlipidemia, diabetes mellitus, and left ventricular hypertrophy did not differ between patients with positive versus negative screens. CONCLUSION/CONCLUSIONS:Current screening practices for primary aldosteronism among patients with comorbid obstructive sleep apnea and hypertension are suboptimal. Patients evaluated at sleep centers may represent an optimal population for screening, as the prevalence of primary aldosteronism among this cohort appears high.

The clinical significance of the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) category 5 thyroid nodules: Not as risky as we think?

Wright, Kyla; Brandler, Tamar C; Fisher, Jason C; Rothberger, Gary D; Givi, Babak; Prescott, Jason; Suh, Insoo; Patel, Kepal N
BACKGROUND:Although the prevalence of thyroid nodules is high, few prove to be malignant. Based on sonographic features, the American College of Radiology Thyroid Imaging Reporting and Data System categorizes malignancy risk of thyroid nodules with associated management recommendations for each category level. Malignancy rates among nodules with a highly suspicious Thyroid Imaging Reporting and Data System category 5 warrant examination in the context of additional risk stratification tools, including cytopathology and molecular testing. METHODS:All patients who underwent fine-needle aspiration biopsy for Thyroid Imaging Reporting and Data System category 5 nodules from January 2018 to September 2021 in a large integrated academic health system were reviewed. Using the Bethesda System for Reporting Thyroid Cytopathology, categories V and VI were set as malignant. Molecular testing (ThyroSeq version 3; Rye Brook, NY) yielding ≥50% risk of malignancy was deemed positive and correlated with surgical pathology. RESULTS:A total of 496 Thyroid Imaging Reporting and Data System category 5 nodules were identified. On fine-needle aspiration cytopathology, 61 (12.3%) were malignant. The breakdown included Bethesda System for Reporting Thyroid Cytopathology I, 15 (3%); II, 362 (73%); III, 52 (10.5%); IV, 5 (1%); V, 6 (1.3%); and VI, 55 (11.1%). Of Bethesda System for Reporting Thyroid Cytopathology III/IV nodules with molecular testing (n = 53), 24.5% yielded positive results. In total, 42 (8.5%) nodules underwent surgical resection, most of which were Bethesda System for Reporting Thyroid Cytopathology VI (n = 26, 61.9%). Of excised nodules, 33 (78.6%) nodules were malignant, 6 (14.3%) benign, and 3 (7.1%) noninvasive follicular thyroid neoplasm with papillary-like nuclear features. All Thyroid Imaging Reporting and Data System category 5 nodules with malignant cytology (Bethesda System for Reporting Thyroid Cytopathology V/VI) that underwent surgery were malignant on histopathology. On average, the total Thyroid Imaging Reporting and Data System points were higher in malignant nodules compared with benign (9.3 vs 7.3; P = .015). Moreover, benign nodules more frequently received Thyroid Imaging Reporting and Data System points when the radiologist was unable to determine composition or echogenicity (33% vs 3% among malignant nodules; P = .01). CONCLUSION/CONCLUSIONS:Thyroid Imaging Reporting and Data System category 5 designation in thyroid nodules is associated with a lower risk of malignancy than previously reported. Benign and malignant nodules with Thyroid Imaging Reporting and Data System category 5 designation have discrepancies in certain Thyroid Imaging Reporting and Data System characteristics and individual points assigned, which may offer an opportunity for quality improvement and standardization measures in ultrasound reporting practices.

Recovery After Thyroid and Parathyroid Surgery: How Do Our Patients Really Feel?

Lee, William G; Gosnell, Jessica E; Shen, Wen T; Duh, Quan-Yang; Suh, Insoo; Chen, Yufei
INTRODUCTION/BACKGROUND:Counseling on the immediate postoperative experience for outpatient procedures is largely based on anecdotal experience. We devised a short messaging service (SMS) survey using mobile phone text messages to evaluate real-time patient recovery following outpatient thyroid or parathyroid surgery. MATERIALS AND METHODS/METHODS:Daily automated SMS surveys were sent the evening of the operation until postoperative day 10. Pain, opioid use, voice quality, and energy levels were assessed. Impaired voice and energy was defined as a score < 2/3 of normal. RESULTS:, preoperative opioid or tobacco use, and history of anxiety or depression. Patients with loss of intraoperative recurrent laryngeal nerve signaling had a significantly worse overall voice score (54.65 versus 92.67, P < 0.001). Up to 10% of patients were still using opioids and/or reported impaired voice and energy levels beyond 1 wk postoperatively. CONCLUSIONS:Real-time SMS survey is an effective and potentially valuable way to monitor patient recovery following surgery. A subset of patients reported impaired voice and energy and was still using opioids beyond 1 wk after thyroid and parathyroid surgery and these patients may benefit from closer follow-up and earlier intervention.

Gordon, Alex J; Dublin, Jared C; Patel, Evan; Papazian, Michael; Chow, Michael S; Persky, Michael J; Jacobson, Adam S; Patel, Kepal N; Suh, Insoo; Morris, Luc G T; Givi, Babak
Importance/UNASSIGNED:Over time, the American Thyroid Association (ATA) guidelines have increasingly promoted more limited treatments for well-differentiated thyroid cancers. Objective/UNASSIGNED:To determine whether the 2009 and 2015 ATA guidelines were associated with changes in the management of low-risk papillary thyroid carcinomas on a national scale. Design, Setting, and Participants/UNASSIGNED:This historical cohort study used the National Cancer Database. All papillary thyroid carcinomas diagnosed from 2004 to 2019 in the National Cancer Database were selected. Patients with tumors of greater than 4 cm, metastases, or clinical evidence of nodal disease were excluded. Data were analyzed from August 1, 2021, to September 1, 2022. Main Outcomes and Measures/UNASSIGNED:The primary aim was to tabulate changes in the rates of thyroid lobectomy (TL), total thyroidectomy (TT), and TT plus radioactive iodine (RAI) therapy after the 2009 and 2015 ATA guidelines. The secondary aim was to determine in which settings (eg, academic vs community) the practice patterns changed the most. Results/UNASSIGNED:A total of 194 254 patients (155 796 [80.2%] female patients; median [range] age at diagnosis, 51 [18-90] years) who underwent treatment during the study period were identified. Among patients who underwent surgery, rates of TL decreased from 15.1% to 13.7% after the 2009 guidelines but subsequently increased to 22.9% after the 2015 changes. Among patients undergoing TT, rates of adjuvant RAI decreased from 48.7% to 37.1% after 2009 and to 19.3% after the 2015 guidelines. Trends were similar for subgroups based on sex and race and ethnicity. However, academic institutions saw larger increases in TL rates (14.9% to 25.7%) than community hospitals (16.3% to 19.5%). Additionally, greater increases in TL rates were observed for tumors 1 to 2 cm (6.8% to 18.9%) and 2 to 4 cm (6.6% to 16.0%) than tumors less than 1 cm (22.8% to 29.2%). Conclusions and Relevance/UNASSIGNED:In this cohort study among patients with papillary thyroid carcinomas up to 4 cm, ATA guideline changes corresponded with increased TL and reduced adjuvant RAI. These changes were primarily seen in academic institutions, suggesting an opportunity to expand guideline-based care in the community setting.

Innovations in Parathyroid Localization Imaging

Graves, Claire E; Duh, Quan-Yang; Suh, Insoo
During cervical surgery, localization and identification of parathyroid glands is key to both the removal of abnormal hyperfunctioning glands and the preservation of normal glands. The challenging nature of parathyroid localization has fostered innovation in imaging techniques to localize glands both before and during cervical operations. Advances in preoperative imaging include PET-based imaging modalities paired with computed tomography or MRI for anatomic correlation. During surgery, both parathyroid autofluorescence and contrast-enhanced fluorescence techniques are useful adjuncts for intraoperative identification.

Adverse Cardiovascular Outcomes Among Older Adults with Primary Hyperparathyroidism Treated with Parathyroidectomy vs. non-operative Management

Seib, Carolyn D; Meng, Tong; Cisco, Robin M; Suh, Insoo; Lin, Dana T; Harris, Alex H S; Trickey, Amber W; Tamura, Manjula Kurella; Kebebew, Electron
OBJECTIVE:We sought to compare the incidence of adverse cardiovascular events in older adults with primary hyperparathyroidism (PHPT) treated with parathyroidectomy versus non-operative management. SUMMARY OF BACKGROUND DATA/BACKGROUND:PHPT is a common endocrine disorder that is associated with increased cardiovascular mortality, but it is not known whether parathyroidectomy reduces the incidence of adverse cardiovascular events. METHODS:We conducted a population-based, longitudinal cohort study of Medicare beneficiaries diagnosed with PHPT (2006-2017). Multivariable, inverse probability weighted Cox proportional hazards regression was used to determine the associations of parathyroidectomy with major adverse cardiovascular events (MACE), cardiovascular disease-related hospitalization, and cardiovascular hospitalization-associated mortality. RESULTS:We identified 210,206 beneficiaries diagnosed with PHPT from 2006-2017. Among 63,136 (30.0%) treated with parathyroidectomy and 147,070 (70.0%) managed non-operatively within one year of diagnosis, the unadjusted incidence of MACE was 10.0% (mean follow-up 59.1 [SD 35.6] months) and 11.5% (mean follow-up 54.1 [SD 34.0] months), respectively. In multivariable analysis, parathyroidectomy was associated with a lower incidence of MACE (HR 0.92 [95%CI 0.90-0.94]), cardiovascular disease-related hospitalization (HR 0.89 [95%CI 0.87-0.91]), and cardiovascular hospitalization-associated mortality (HR 0.76 [95%CI 0.71-0.81]) compared to non-operative management. At 10 years, parathyroidectomy was associated with adjusted absolute risk reduction for MACE of 1.7% (95%CI 1.3%-2.1%), for cardiovascular disease-related hospitalization of 2.5% (95%CI 2.1%-2.9%), and for cardiovascular hospitalization-associated mortality of 1.4% (95%CI 1.2%-1.6%). CONCLUSIONS:In this large, population-based cohort study, parathyroidectomy was associated with a lower long-term incidence of adverse cardiovascular outcomes when compared with non-operative management for older adults with PHPT, which is relevant to surgical decision-making for patients with a long life expectancy.

OBJECTIVE:Cancer patients and survivors may be disproportionately affected by COVID-19. We sought to determine the effects of the pandemic on thyroid cancer survivors' healthcare interactions and quality of life. METHODS:An anonymous survey including questions about COVID-19 and the Patient-Reported Outcomes Measurement Information System profile (PROMIS-29, version 2.0) was hosted on the ThyCa:Thyroid Cancer Survivors' Association, Inc. website. PROMIS scores were compared to previously published data. Factors associated with greater anxiety were evaluated with univariable and multivariable logistic regression. RESULTS:From 5/6/2020 - 10/8/2020, 413 participants consented to take the survey; 378 (92%) met inclusion criteria: diagnosed with thyroid cancer or NIFTP, within the United States, and completing all sections of the survey. Mean age was 53 years; 89% were female, and 74% had papillary thyroid cancer. Most respondents agreed/strongly agreed (83%) that their lives were very different during COVID-19, as was their interaction with doctors (79%). A minority (43%) were satisfied with information from their doctor regarding COVID-19 changes. Compared to pre-COVID-19, PROMIS scores were higher for anxiety (57.8 vs. 56.5, p<0.05) and lower for ability to participate in social activities (46.2 vs. 48.1, p<0.01), fatigue (55.8 vs. 57.9, p<0.01), and sleep disturbance (54.7 vs. 56.1, p<0.01). After adjusting for confounders, greater anxiety was associated with younger age (p<0.01) and change in treatment plan (p=0.04). CONCLUSIONS:During the COVID-19 pandemic, thyroid cancer survivors reported increased anxiety compared to a pre-COVID cohort. To deliver comprehensive care, providers must better understand patient concerns and improve communication about potential changes to their treatment plans.
