Importance: Although intensive follow-up of patients after curative surgery for colorectal cancer is common in clinical practice, evidence for a long-term survival benefit of more frequent testing is limited.

Objective: To examine overall and colorectal cancer-specific mortality rates in patients with stage II or III colorectal cancer who underwent curative surgery and underwent high-frequency or low-frequency follow-up testing.

Design, setting, and participants: This randomized clinical trial with posttrial prespecified follow-up was performed in 23 centers in Sweden and Denmark. The original study enrolled 2509 patients with stage II or III colorectal cancer from Sweden, Denmark, and Uruguay (1 center) who received treatment from January 1, 2006, through December 31, 2010, and were followed up for up to 5 years. The participants from Sweden and Denmark were then followed up for 10 years through population-based health registries. The 53 patients from Uruguay were not included in the posttrial follow-up. Statistical analysis was performed from March to June 2024.

Interventions: Patients were randomly allocated to follow-up testing with computed tomography (CT) scans and serum carcinoembryonic antigen (CEA) screening at 6, 12, 18, 24, and 36 months after surgery (high-frequency group; 1227 patients), or at 12 and 36 months after surgery (low-frequency group, 1229 patients).

Main outcomes and measures: The outcomes were 10-year overall mortality and colorectal cancer-specific mortality rates. Both intention-to-treat and per-protocol analyses were performed.

Results: Of the 2555 patients who were randomly allocated, 2509 were included in the intention-to-treat analysis, of whom 2456 (97.9%) were included in this posttrial analysis (median age, 65 years [IQR, 59-70 years]; 1355 male patients [55.2%]). The 10-year overall mortality rate for the high-frequency group was 27.1% (333 of 1227; 95% CI, 24.7%-29.7%) compared with 28.4% (349 of 1229; 95% CI, 26.0%-31.0%) in the low-frequency group (risk difference, 1.3% [95% CI, -2.3% to 4.8%]). The 10-year colorectal cancer-specific mortality rate in the high-frequency group was 15.6% (191 of 1227; 95% CI, 13.6%-17.7%) compared with 16.0% (196 of 1229; 95% CI, 14.0%-18.1%) in the low-frequency group (risk difference, 0.4% [95% CI, -2.5% to 3.3%]). The same pattern resulted from the per-protocol analysis.

Conclusions and relevance: Among patients with stage II or III colorectal cancer, more frequent follow-up testing with CT scans and CEA testing did not result in a significant reduction in 10-year overall mortality or colorectal cancer-specific mortality. The results of this trial should be considered as the evidence base for updating clinical guidelines.

Importance: Prostate cancer (PC) care has evolved rapidly as a result of changes in prostate-specific antigen testing, novel imaging, and newer treatments. The impact of these changes on PC epidemiology and racial disparities across disease states remains underexplored.

Objective: To characterize racial and ethnic differences in the epidemiology of PC states, including nonmetastatic hormone-sensitive PC (nmHSPC), metastatic HSPC (mHSPC), nonmetastatic castration-resistant PC (nmCRPC), and metastatic CRPC (mCRPC).

Design, setting, and participants: This is a retrospective, population-based cohort study of male US veterans aged 40 years and older with known race and ethnicity and no non-PC malignant neoplasm before study entry receiving care through the Veterans Health Administration. The study period was from 2012 to 2020, with follow-up through 2021. To identify active users, data capture included visits 18 months before and after the study period. Data analysis was performed from March to August 2023.

Exposure: Self-identified race and ethnicity, classified as Black, White, or Hispanic.

Main outcomes and measures: The primary outcomes were annual age-adjusted incidence rates (IRs) and point prevalence for PC states by race and ethnicity. Trends were evaluated using joinpoint regression. Time to disease progression or death was estimated using nonparametric cumulative incidence. Competing risk models adjusted for age assessed the association of race and ethnicity on disease progression.

Results: The study included 6 539 001 veterans (median [IQR] age, 65 [56-74] years), of whom 476 227 had PC (median [IQR] age, 69 [63-75] years). IRs varied by time frame and disease state. Across all states and years, the relative risk among Black vs White patients ranged from 2.09 (95% CI, 2.01-2.18; P < .001) for nmHSPC in 2012 to 4.12 (95% CI, 3.39-5.02; P < .001) for nmCRPC in 2017. In nmHSPC, hazard ratios for progression to mHSPC and nmCRPC were 1.36 (95% CI, 1.33-1.40) and 1.60 (95% CI, 1.51-1.70), respectively, for Black patients and 1.38 (95% CI, 1.31-1.45) and 1.55 (95% CI, 1.40-1.72), respectively, for Hispanic patients vs White patients. In contrast, in mCRPC, the hazard ratio for death was lower for Black (0.84; 95% CI, 0.81-0.88) and Hispanic (0.76; 95% CI, 0.69-0.83) patients compared with White patients.

Conclusions and relevance: This cohort study of veterans found that Black patients had more than 2-fold higher incidence of all disease states vs White patients. Progression risk was higher for Black and Hispanic patients in early-stage disease, but lower in later disease stages. Despite equal access, Black patients disproportionately experience PC, although progression risks relative to White patients differed according to disease state.

Importance: Few studies have explored the association between sexual and gender minority (SGM) status and occupational well-being among health care workers.

Objectives: To assess the prevalence of burnout, professional fulfillment, intent to leave, anxiety, and depression by self-reported SGM status.

Design, setting, and participants: This cross-sectional survey study collected data from October 2019 to July 2021, from 8 academic medical institutions participating in the Healthcare Professional Well-Being Academic Consortium. The survey, including questions on SGM status, was administered to attending physicians and trainees. Statistical analyses were performed from June 1, 2023, to February 29, 2024.

Exposure: SGM status was determined via self-reported sexual orientation and gender identity.

Main outcomes and measures: Primary outcomes measured were the Professional Fulfillment Index (burnout and professional fulfillment), intent to leave, and self-reported anxiety and depression using the Patient-Reported Outcomes Measurement Information System short-form 4-item measure.

Results: Of 20 541 attendings and 6900 trainees, 8376 attendings and 2564 trainees responded and provided SGM status. Of these respondents, 386 attendings (4.6%) and 212 trainees (8.3%) identified as SGM. Compared with their non-SGM peers, SGM attendings had a lower prevalence of professional fulfillment (133 of 386 [34.5%] vs 3200 of 7922 [40.4%]) and a higher prevalence of burnout (181 of 382 [47.4%] vs 2791 of 7883 [35.4%]) and intent to leave (125 of 376 [33.2%] vs 2433 of 7873 [30.9%]) (all P < .001). Compared with their non-SGM peers, SGM trainees had a lower prevalence of professional fulfillment (63 of 211 [29.9%] vs 833 of 2333 [35.7%]) and a higher prevalence of burnout (108 of 211 [51.2%] vs 954 of 2332 [40.9%]) (both P < .001). After adjusting for age and race and ethnicity, SGM attendings had higher odds of burnout than their non-SGM peers (adjusted odds ratio, 1.57 [95% CI, 1.27-1.94]; P < .001). Results for burnout were similar among the SGM trainees compared with their non-SGM peers (adjusted odds ratio, 1.47 [1.10-1.96]; P = .01).

Conclusions and relevance: In this cross-sectional survey study of academic physicians and trainees, SGM attendings and trainees had higher levels of burnout and lower levels of professional fulfillment. SGM attendings had greater intent to leave than their non-SGM peers, but trainees did not. These disparities represent an opportunity for further exploration to retain SGM health care workers.

Importance: High emergency department (ED) pediatric readiness is associated with improved survival among children receiving emergency care, but state and national costs to reach high ED readiness and the resulting number of lives that may be saved are unknown.

Objective: To estimate the state and national annual costs of raising all EDs to high pediatric readiness and the resulting number of pediatric lives that may be saved each year.

Design, setting, and participants: This cohort study used data from EDs in 50 US states and the District of Columbia from 2012 through 2022. Eligible children were ages 0 to 17 years receiving emergency services in US EDs and requiring admission, transfer to another hospital for admission, or dying in the ED (collectively termed at-risk children). Data were analyzed from October 2023 to May 2024.

Exposure: EDs considered to have high readiness, with a weighted pediatric readiness score of 88 or above (range 0 to 100, with higher numbers representing higher readiness).

Main outcomes and measures: Annual hospital expenditures to reach high ED readiness from current levels and the resulting number of pediatric lives that may be saved through universal high ED readiness.

Results: A total 842 of 4840 EDs (17.4%; range, 2.9% to 100% by state) had high pediatric readiness. The annual US cost for all EDs to reach high pediatric readiness from current levels was $207 335 302 (95% CI, $188 401 692-$226 268 912), ranging from $0 to $11.84 per child by state. Of the 7619 child deaths occurring annually after presentation, 2143 (28.1%; 95% CI, 678-3608) were preventable through universal high ED pediatric readiness, with population-adjusted state estimates ranging from 0 to 69 pediatric lives per year.

Conclusions and relevance: In this cohort study, raising all EDs to high pediatric readiness was estimated to prevent more than one-quarter of deaths among children receiving emergency services, with modest financial investment. State and national policies that raise ED pediatric readiness may save thousands of children's lives each year.
