Importance: Routine preoperative blood tests and electrocardiograms before low-risk surgery do not prevent adverse events or change management but waste resources and can cause patient harm. Given this, multispecialty organizations recommend against routine testing before low-risk surgery.

Objective: To determine whether a multicomponent deimplementation strategy (the intervention) would reduce low-value preoperative testing before low-risk general surgery operations.

Introduction: Thyroid cancer diagnosis often evokes strong negative emotions in patients, yet little is understood about such responses in those with benign thyroid nodules. This study explored the impact of a hypothetical cancer diagnosis, the provision of treatment information, and emotional support from surgeons on patients with benign nodules.

Methods: Patients within 30 d of a thyroid nodule biopsy were asked to imagine their nodule was cancerous and write down their feelings about this diagnosis.

Background: Although primary hyperparathyroidism (PHPT) is readily diagnosed biochemically and can be cured with low-risk surgery, it is often underrecognized and undertreated. Our objectives were to characterize, within our health system, how often patients with hypercalcemia were evaluated for PHPT and how often patients with PHPT underwent definitive treatment with parathyroidectomy.

Methods: Ambulatory patients aged 18 years or older seen at our health system between January 2018 and June 2023 with chronic hypercalcemia were identified from the medical record.

While patient-level determinants of total thyroidectomy use have been well described, surgeon-level drivers of more extensive surgery are present and less well described. This survey sought to examine the associations between surgeons' operative recommendations, their beliefs about cancer, and their attitudes about medical maximizing-minimizing. A mixed-mode, cross-sectional survey was administered in September 2020 via mail and email to 222 thyroid surgeons identified in the Centers for Medicare & Medicaid Services Provider Utilization and Payment Physician and Other Practitioners dataset.

Background: Spanish-speaking trauma and burn patients have unique needs in their postdischarge care navigation. The confluence of limited English proficiency, injury recovery, mental health, socioeconomic disadvantages, and acute stressors after hospital admission converge to enhance patients' vulnerability, but their specific needs and means of meeting these needs have not been well described.

Study Design: This prospective, cross-sectional survey study describes the results of a multi-institutional initiative devised to help Spanish-speaking trauma and burn patients in their care navigation after hospitalization.

Article Synopsis
  • The study evaluates how patients with low-risk thyroid cancer prioritize treatment outcomes after their surgical choices, emphasizing the emotional impact of their diagnosis on decision-making.
  • Participants rated outcomes at the time of surgery decision and again after 9 months, revealing that patients' valuations changed significantly over time.
  • Results indicate that after experiencing treatment, patients shifted focus from concerns about cancer recurrence to valuing quality of life aspects like energy levels, suggesting surgeons need to consider these changing priorities in discussions about treatment options.

Introduction: Consensus is lacking regarding the optimal strategy to influence surgeons' behaviors to reduce low-value surgical care. Comprehensively describing the existing body of literature that seeks to intervene on surgeons' preoperative decision-making may aid in structuring future behavior change strategies.

Methods: We performed a scoping review using four databases (Medical Literature Analysis and Retrieval System Online, Embase, Web of Science, and Cumulated Index to Nursing and Allied Health Literature) for articles that tested the effect of behavioral-based interventions on any aspect of surgeons' decision-making in the preoperative setting.

Background: Intraoperative parathyroid hormone (IOPTH) monitoring is used to predict biochemical cure during parathyroidectomy for primary hyperparathyroidism; however, there is variability in the intraoperative parathyroid hormone criteria used by surgeons to predict normocalcemia after parathyroidectomy. This study sought to determine the intraoperative parathyroid hormone criteria correlated with the lowest rates of persistent hyperparathyroidism after parathyroidectomy for primary hyperparathyroidism.

Materials And Methods: This is a retrospective cohort study of 2,654 patients with primary hyperparathyroidism who underwent parathyroidectomy with intraoperative parathyroid hormone monitoring at a single institution from 1999 to 2014.
