ABSTRACT Background Post‐pancreatectomy exocrine insufficiency is common after resection for pancreatic cancer and requires pancreatic enzyme replacement therapy (PERT). We sought to determine the out‐of‐pocket cost of PERT and the association between PERT and survival. Methods The SEER‐linked Medicare database was queried for patients with pancreatic cancer who underwent pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) from 2010 to 2019. Cumulative out‐of‐pocket costs were calculated and stratified by procedure and radiation. Results 11,854 Medicare beneficiaries with resected pancreatic cancer were identified, 4,653 (39%) required PERT and 7,201 (61%) did not. Median age was 73.0, 50.6% were female and 83.6% White. 25.9% underwent DP and 74.1% underwent PD; 7% received neoadjuvant radiation while 23.5% received adjuvant radiation. Logistic regression demonstrated that female sex (OR 1.25, 95% CI 1.16‐1.35, p < 0.001), neoadjuvant radiation (OR 1.93, 95% CI 1.67‐2.24, p < 0.001), and PD (OR 2.45, 95% CI 2.23‐2.7, p < 0.001) were risk factors for requiring PERT. Patients without subsidies who underwent DP paid a cumulative $4,736 out‐of‐pocket for PERT after 5 years, those who underwent PD paid $5,601 out‐of‐pocket. Conclusions Nearly 40% of Medicare beneficiaries took PERT after resection for pancreatic cancer and paid thousands in out‐of‐pocket costs. While a conservative estimate, these findings highlight the importance of addressing this financial burden to patients.

Background: ASCO recommends extended venous thromboembolism (VTE) prophylaxis with low-molecular-weight heparin (LMWH) or direct oral anticoagulants (DOACs) following cancer surgery. However, these recommendations were based on trials using routine venography, which detects asymptomatic VTEs, and real-life efficacy is not well studied. We aimed to assess the association of extended VTE prophylaxis with the incidence of clinically significant VTE after elective cancer surgery. Patients and Methods: In this retrospective, population-based cohort study, we identified patients who underwent surgical resection for lung, breast, esophageal, gastric, pancreas, and colon cancer from 2010 to 2017 using the SEER–Medicare linked dataset. Patients were divided into 1 of 2 main groups for comparative analyses: those who received extended VTE prophylaxis after cancer surgery and those who did not. Patients who received extended VTE prophylaxis after cancer surgery were identified as those prescribed prophylactic doses of LMWH or a DOAC within 7 days of discharge, as captured in Medicare Part D files. Results: A total of 113,739 Medicare beneficiaries were identified, of whom 1,570 (1.4%) received extended VTE prophylaxis. There was a year-over-year increase in the use of extended VTE prophylaxis during the study period, rising from 0.6% in 2010 to 3.3% in 2017. The overall incidence of VTE was 1.6% at 1 month, 4.3% at 6 months, 5.7% at 12 months, with significant differences observed across cancer types ( P <.001). However, patients who received extended VTE prophylaxis had a higher 1-year cumulative incidence of postoperative VTE compared with those who did not (11.4% vs 5.3%; P <.001), an association that was consistent across cancer sites. In adjusted analyses, extended VTE prophylaxis was independently associated with an increased risk of VTE (hazard ratio, 1.6; 95% CI, 1.3–2.0; P <.001). Extended prophylaxis was also associated with a higher 1-year incidence of bleeding events compared with patients who did not receive prophylaxis (12.0% vs 8.5%; P <.001). Conclusions: The utilization of extended VTE prophylaxis after cancer surgery remains low, although it has increased every year. Paradoxically, patients who received extended VTE prophylaxis had higher incidences of clinically significant VTE and bleeding compared with those who did not, likely reflecting patient selection and surveillance bias after surgery. In light of these findings, national guidelines recommending postoperative extended VTE prophylaxis, and its use as a surrogate for quality of care, should continue to be re-examined.

Objective: To characterize the current state of mental health within the surgical workforce in the United States. Background: Mental illness and suicide is a growing concern in the medical community; however, the current state is largely unknown. Methods: Cross-sectional survey of the academic surgery community assessing mental health, medical error, and suicidal ideation. The odds of suicidal ideation adjusting for sex, prior mental health diagnosis, and validated scales screening for depression, anxiety, post-traumatic stress disorder (PTSD), and alcohol use disorder were assessed. Results: Of 622 participating medical students, trainees, and surgeons (estimated response rate=11.4%–14.0%), 26.1% (141/539) reported a previous mental health diagnosis. In all, 15.9% (83/523) of respondents screened positive for current depression, 18.4% (98/533) for anxiety, 11.0% (56/510) for alcohol use disorder, and 17.3% (36/208) for PTSD. Medical error was associated with depression (30.7% vs. 13.3%, P<0.001), anxiety (31.6% vs. 16.2%, P=0.001), PTSD (12.8% vs. 5.6%, P=0.018), and hazardous alcohol consumption (18.7% vs. 9.7%, P=0.022). Overall, 13.2% (73/551) of respondents reported suicidal ideation in the past year and 9.6% (51/533) in the past 2 weeks. On adjusted analysis, a previous history of a mental health disorder (aOR: 1.97, 95% CI: 1.04–3.65, P=0.033) and screening positive for depression (aOR: 4.30, 95% CI: 2.21–8.29, P<0.001) or PTSD (aOR: 3.93, 95% CI: 1.61–9.44, P=0.002) were associated with increased odds of suicidal ideation over the past 12 months. Conclusions: Nearly 1 in 7 respondents reported suicidal ideation in the past year. Mental illness and suicidal ideation are significant problems among the surgical workforce in the United States.
