Background: Colorectal cancer (CRC) screening programs based on fecal immunochemical tests (FITs) represent the standard of care for population-based interventions. Their benefit depends on the identification of neoplasia at colonoscopy after FIT positivity. Colonoscopy quality measured by adenoma detection rate (ADR) may affect screening program effectiveness. Objective: To examine the association between ADR and postcolonoscopy CRC (PCCRC) risk in a FIT-based screening program. Design: Retrospective population-based cohort study. Setting: Fecal immunochemical test–based CRC screening program between 2003 and 2021 in northeastern Italy. Patients: All patients with a positive FIT result who had a colonoscopy were included. Measurements: The regional cancer registry supplied information on any PCCRC diagnosed between 6 months and 10 years after colonoscopy. Endoscopists' ADR was categorized into 5 groups (20% to 39.9%, 40% to 44.9%, 45% to 49.9%, 50% to 54.9%, and 55% to 70%). To examine the association of ADR with PCCRC incidence risk, Cox regression models were fitted to estimate hazard ratios (HRs) and 95% CIs. Results: Of the 110 109 initial colonoscopies, 49 626 colonoscopies done by 113 endoscopists between 2012 and 2017 were included. After 328 778 person-years follow-up, 277 cases of PCCRC were diagnosed. Mean ADR was 48.3% (range, 23% and 70%). Incidence rates of PCCRC from lowest to highest ADR group were 13.13, 10.61, 7.60, 6.01, and 5.78 per 10 000 person-years. There was a significant inverse association between ADR and PCCRC incidence risk, with a 2.35-fold risk increase (95% CI, 1.63 to 3.38) in the lowest group compared with the highest. The adjusted HR for PCCRC associated with 1% increase in ADR was 0.96 (CI, 0.95 to 0.98). Limitation: Adenoma detection rate is partly determined by FIT positivity cutoff; exact values may vary in different settings. Conclusion: In a FIT-based screening program, ADR is inversely associated with PCCRC incidence risk, mandating appropriate colonoscopy quality monitoring in this setting. Increasing endoscopists' ADR may significantly reduce PCCRC risk. Primary Funding Source: None.

15-Year Benefits of Sigmoidoscopy Screening on Colorectal Cancer Incidence and Mortality: A Pooled Analysis of Randomized Trials: Annals of Internal Medicine: Vol 175, No 11

Background: The effectiveness of screening for colorectal cancer (CRC) by sex and age in randomized trials is uncertain. Objective: To evaluate the 15-year effect of sigmoidoscopy screening on CRC incidence and mortality. Design: Pooled analysis of 4 large-scale randomized trials of sigmoidoscopy screening. Setting: Norway, the United States, the United Kingdom, and Italy. Participants: Women and men aged 55 to 64 years at enrollment. Intervention: Sigmoidoscopy screening. Measurements: Primary end points were cumulative incidence rate ratio (IRR) and mortality rate ratio (MRR) and rate differences after 15 years of follow-up comparing screening versus usual care in intention-to-treat analyses. Stratified analyses were done by sex, cancer site, and age at screening. Results: Analyses comprised 274 952 persons (50.7% women), 137 493 in the screening and 137 459 in the usual care group. Screening attendance was 58% to 84%. After 15 years, the rate difference for CRC incidence was 0.51 cases (95% CI, 0.40 to 0.63 cases) per 100 persons and the IRR was 0.79 (CI, 0.75 to 0.83). The rate difference for CRC mortality was 0.13 deaths (CI, 0.07 to 0.19 deaths) per 100 persons, and the MRR was 0.80 (CI, 0.72 to 0.88). Women had less benefit from screening than men for CRC incidence (IRR for women, 0.84 [CI, 0.77 to 0.91]; IRR for men, 0.75 [CI, 0.70 to 0.81]; P = 0.032 for difference) and mortality (MRR for women, 0.91 [CI, 0.77 to 1.17]; MRR for men, 0.73 [CI, 0.64 to 0.83]; P = 0.025 for difference). There was no statistically significant difference in screening effect between persons aged 55 to 59 years and those aged 60 to 64 years. Limitation: Data from the U.K. trial were less granular because of privacy regulations. Conclusion: This pooled analysis of all large randomized trials of sigmoidoscopy screening demonstrates a significant and sustained effect of sigmoidoscopy on CRC incidence and mortality for 15 years.

How the Gender Wage Gap for Primary Care Physicians Differs by Compensation Approach: A Microsimulation Study: Annals of Internal Medicine: Vol 175, No 8

Background: The physician gender wage gap may be due, in part, to productivity-based compensation models that undervalue female practice patterns. Objective: To determine how primary care physician (PCP) compensation by gender differs when applying existing productivity-based and alternative compensation models. Design: Microsimulation. Setting: 2016 to 2019 national clinical registry of 1222 primary care practices. Participants: Male and female PCPs matched on specialty, years since medical school graduation, practice site, and sessions worked. Measurements: Net annual, full-time-equivalent compensation for male versus female PCPs, under productivity-based fee-for-service, panel size–based capitation without or with risk adjustment, and hybrid payment models. Microsimulation inputs included patient and visit characteristics and overhead expenses. Results: Among 1435 matched male (n = 881) and female (n = 554) PCPs, female PCP panels included patients who were, on average, younger, had lower diagnosis-based risk scores, were more often female, and were more often uninsured or insured by Medicaid rather than by Medicare. Under productivity-based payment, female PCPs earned a median of $58 829 (interquartile range [IQR], $39 553 to $120 353; 21%) less than male PCPs. This gap was similar under capitation ($58 723 [IQR, $42 141 to $140 192]). It was larger under capitation risk-adjusted for age alone ($74 695 [IQR, $42 884 to $152 423]), for diagnosis-based scores alone ($114 792 [IQR, $49 080 to $215 326] and $89 974 [IQR, $26 175 to $173 760]), and for age-, sex-, and diagnosis-based scores ($83 438 [IQR, $28 927 to $129 414] and $66 195 [IQR, $11 899 to $96 566]). The gap was smaller and nonsignificant under capitation risk-adjusted for age and sex ($36 631 [IQR, $12 743 to $73 898]). Limitation: Panel attribution based on office visits. Conclusion: The gender wage gap varied by compensation model, with capitation risk-adjusted for patient age and sex resulting in a smaller gap. Future models might better align with primary care effort and outcomes. Primary Funding Source: None.

Maternal, Infant, and Child Health Outcomes Associated With the Special Supplemental Nutrition Program for Women, Infants, and Children: A Systematic Review: Annals of Internal Medicine: Vol 175, No 10

Background: The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is intended to improve maternal and child health outcomes. In 2009, the WIC food package changed to better align with national nutrition recommendations. Purpose: To determine whether WIC participation was associated with improved maternal, neonatal–birth, and infant–child health outcomes or differences in outcomes by subgroups and WIC enrollment duration. Data Sources: Search (January 2009 to April 2022) included PubMed, Embase, CINAHL, ERIC, Scopus, PsycInfo, and the Cochrane Central Register of Controlled Trials. Study Selection: Included studies had a comparator of WIC-eligible nonparticipants or comparison before and after the 2009 food package change. Data Extraction: Paired team members independently screened articles for inclusion and evaluated risk of bias. Data Synthesis: We identified 20 observational studies. We found: moderate strength of evidence (SOE) that maternal WIC participation during pregnancy is likely associated with lower risk for preterm birth, low birthweight infants, and infant mortality; low SOE that maternal WIC participation may be associated with a lower likelihood of inadequate gestational weight gain, as well as increased well-child visits and childhood immunizations; and low SOE that child WIC participation may be associated with increased childhood immunizations. We found low SOE for differences in some outcomes by race and ethnicity but insufficient evidence for differences by WIC enrollment duration. We found insufficient evidence related to maternal morbidity and mortality outcomes. Limitation: Data are from observational studies with high potential for selection bias related to the choice to participate in WIC, and participation status was self-reported in most studies. Conclusion: Participation in WIC was likely associated with improved birth outcomes and lower infant mortality, and also may be associated with increased child preventive service receipt.

Comparative Effectiveness and Safety Between Apixaban, Dabigatran, Edoxaban, and Rivaroxaban Among Patients With Atrial Fibrillation: A Multinational Population-Based Cohort Study: Annals of Internal Medicine: Vol 175, No 11

Background: Current guidelines recommend using direct oral anticoagulants (DOACs) over warfarin in patients with atrial fibrillation (AF), but head-to-head trial data do not exist to guide the choice of DOAC. Objective: To do a large-scale comparison between all DOACs (apixaban, dabigatran, edoxaban, and rivaroxaban) in routine clinical practice. Design: Multinational population-based cohort study. Setting: Five standardized electronic health care databases, which covered 221 million people in France, Germany, the United Kingdom, and the United States. Participants: Patients who were newly diagnosed with AF from 2010 through 2019 and received a new DOAC prescription. Measurements: Database-specific hazard ratios (HRs) of ischemic stroke or systemic embolism, intracranial hemorrhage (ICH), gastrointestinal bleeding (GIB), and all-cause mortality between DOACs were estimated using a Cox regression model stratified by propensity score and pooled using a random-effects model. Results: A total of 527 226 new DOAC users met the inclusion criteria (apixaban, n = 281 320; dabigatran, n = 61 008; edoxaban, n = 12 722; and rivaroxaban, n = 172 176). Apixaban use was associated with lower risk for GIB than use of dabigatran (HR, 0.81 [95% CI, 0.70 to 0.94]), edoxaban (HR, 0.77 [CI, 0.66 to 0.91]), or rivaroxaban (HR, 0.72 [CI, 0.66 to 0.79]). No substantial differences were observed for other outcomes or DOAC–DOAC comparisons. The results were consistent for patients aged 80 years or older. Consistent associations between lower GIB risk and apixaban versus rivaroxaban were observed among patients receiving the standard dose (HR, 0.72 [CI, 0.64 to 0.82]), those receiving a reduced dose (HR, 0.68 [CI, 0.61 to 0.77]), and those with chronic kidney disease (HR, 0.68 [CI, 0.59 to 0.77]). Limitation: Residual confounding is possible. Conclusion: Among patients with AF, apixaban use was associated with lower risk for GIB and similar rates of ischemic stroke or systemic embolism, ICH, and all-cause mortality compared with dabigatran, edoxaban, and rivaroxaban. This finding was consistent for patients aged 80 years or older and those with chronic kidney disease, who are often underrepresented in clinical trials. Primary Funding Source: None.
