RESUMO
OBJECTIVE: This study describes differences in postoperative mortality for pediatric patients in rural communities compared to urban communities. BACKGROUND: Canada has the second largest land mass in the world, with a population density of 4 people per km2. There are 18 children's hospitals in Canada offering pediatric surgical services, all in urban centres, yet nearly one-fifth of the population lives in rural or remote communities. Children who live in rural settings may have worse surgical outcomes, including mortality rates, compared with urban populations. METHODS: Pediatric patients, from birth to 18 years old, who had surgery from January 1, 2011, to December 31, 2021, at a single Children's Hospital were included in the study. Data was obtained from the provincial Operating Room Information System (ORIS) database. Postal code, rural and urban status, distance to children's hospital (0-50 km, 51-100 km, 101-150 km, 151-200 km, and >200 km), and procedure urgency were collected. 30-day mortality for all procedures was collected. RESULTS: 85,998 surgical procedures were performed at ACH between 2011 and 2021. 17,773 (20.7%) of patients lived >50 km or more from the hospital - 5,329 (6.2%) 51- 100 km, 4,053 (4.7%) 101-150 km, n=2,323 (2.7%) 151-200 km, and 6,070 (7.1%) >200 km. Rural patients had higher 30-day mortality rates than urban patients, with an odds ratio of mortality (rural vs urban) of 2.30 (95% CI, 0.95 to 5.60). When stratified by distance, patients living closer to the hospital (0-50 km) had lower odds of mortality. CONCLUSIONS: Canadian Rural patients have higher operative mortality risks than urban patients. This study identifies a vulnerable group of patients who do not have equal access to care and may experience worse outcomes.
RESUMO
AIM: There are several case reports describing patients with both optic nerve hypoplasia/septo-optic-pituitary dysplasia (ONH/SOD) and gastroschisis (GS). Our aim was to investigate whether ONH/SOD is associated with GS. METHODS: A retrospective population-based study was undertaken using the Population Research Data Repository at the Manitoba Center for Health Policy in Manitoba, Canada to investigate if any patient with ONH/SOD also had GS. In addition, Winnipeg's Surgical Database of Outcomes and Management (WiSDOM), a hospital-based paediatric surgical database, was searched to ascertain if any of the patients with GS also have ONH/SOD. RESULTS: Cases were 124 patients with ONH/SOD diagnosed during 1990-2019. None had GS. The surgical database had 188 patients from Manitoba with GS during 1991-2019. None had ONH/SOD. CONCLUSION: There does not appear to be an association between ONH/SOD and GS in our cohorts of patients with these two disorders.

Objective: To examine plans for postpartum cannabis use among pregnant individuals who used cannabis during early pregnancy. Materials and Methods: Eighteen virtual focus groups were conducted from November 17, 2021, to December 17, 2021, with 23 Black and 30 White pregnant adults in Kaiser Permanente Northern California, who self-reported prenatal cannabis use during early pregnancy. Focus groups were recorded, transcribed, and analyzed using thematic analysis. Results: The sample (N = 53) had a mean age of 30.3 years (standard deviation = 5.2) at recruitment; 70% reported daily, 25% weekly, and 6% ≤ monthly cannabis use at entrance to prenatal care. Some participants viewed cannabis as critical for coping with postpartum mental and physical health challenges, while others questioned whether cannabis use would fit with their parental lifestyle, and some planned to abstain altogether. Most planned to use cannabis postpartum, but with lower frequency than before pregnancy, and in ways consistent with harm reduction (e.g., smoking outside to avoid secondhand or thirdhand smoke exposure). Many were motivated to abstain from cannabis while breastfeeding, and some desired more data on the safety of cannabis and breastfeeding, or intended to "pump and dump," believing it would reduce potential transfer of Δ9-tetrahydrocannabinol (THC) to their infant. Responses from Black and White participants were generally similar, but White participants were more likely to report plans to use cannabis while breastfeeding and to want information about cannabis and breastfeeding. Conclusions: Pregnant individuals with prenatal cannabis use had varied plans for cannabis use postpartum. Many were motivated to abstain or use cannabis less frequently than pre-pregnancy, especially during lactation.

OBJECTIVES: A national survey aimed to measure how men with prostate cancer perceived their involvement in and decisions around their care immediately after diagnosis. This study aimed to describe any differences found by socio-demographic groups. DESIGN: Cross-sectional study of men who were diagnosed with and treated for prostate cancer. SETTING: The National Prostate Cancer Audit patient-reported experience measures (PREMs) survey in England. PARTICIPANTS: Men diagnosed in 2014-2016, with non-metastatic prostate cancer, were surveyed. Responses from 32 796 men were individually linked to records from a national clinical audit and to administrative hospital data. Age, ethnicity, deprivation and disease risk classification were used to explore variation in responses to selected questions. PRIMARY AND SECONDARY OUTCOME MEASURES: Responses to five questions from the PREMs survey: the proportion responding to the highest positive category was compared across the socio-demographic characteristics above. RESULTS: When adjusted for other factors, older men were less likely than men under the age of 60 to feel side effects had been explained in a way they could understand (men 80+: relative risk (RR)=0.92, 95% CI 0.84 to 1.00), that their views were considered (RR=0.79, 95% CI 0.73 to 0.87) or that they were involved in decisions (RR=0.92, 95% CI 0.85 to 1.00). The latter was also apparent for men who were not white (black men: RR=0.89, 95% CI 0.82 to 0.98; Asian men: RR=0.85, 95% CI 0.75 to 0.96) and, to a lesser extent, for more deprived men. CONCLUSIONS: The observed discrepancies highlight the need for more focus on initiatives to improve the experience of ethnic minority patients and those older than 60 years. The findings also argue for further validation of discriminatory instruments to help cancer care providers fully understand the variation in the experience of their patients.

OBJECTIVES: We assessed how often National Health Service (NHS) hospitals reported that they had specific supportive services for patients with prostate cancer available onsite, including nursing support, sexual function and urinary continence services, psychological and genetic counselling, and oncogeriatric services. We identified groups of hospitals with similar patterns of supportive services. DESIGN/SETTING: We conducted an organisational survey in 2021 of all NHS hospitals providing prostate cancer services in England and Wales. Latent class analysis grouped hospitals with similar patterns of supportive services. RESULTS: In 138 hospitals, an advanced prostate cancer nurse was available in 125 hospitals (90.6%), 107 (77.5%) had a clinical nurse specialist (CNS) attending all clinics, 103 (75.7%) had sexual function services, 111 (81.6%) had continence services and 93 (69.4%) psychological counselling. The availability of genetic counselling (41 hospitals, 30.6%) and oncogeriatric services (15 hospitals, 11.0%) was lower. The hospitals could be divided into three groups. The first and largest group of 85 hospitals provided the most comprehensive supportive services onsite: all hospitals had a CNS attending all clinics, 84 (98.8%) sexual function services and 73 (85.9%) continence services. A key characteristic of the second group of 31 hospitals was that none had a CNS attending all clinics. A key characteristic of the third group of 22 hospitals was that none had sexual function services available. The hospitals in the largest group were more likely to run joint clinics (p<0.001) and host the regional specialist multidisciplinary team (p=0.002). CONCLUSIONS: There is considerable variation in supportive services for prostate cancer available onsite in NHS hospitals in England and Wales. Availability of genetic counselling and oncogeriatric services is low. The different patterns of supportive services among hospitals demonstrate that initiatives to improve the availability of the entire range of supportive services to all patients should be carefully targeted.

OBJECTIVE: To report the 5-year failure-free survival (FFS) following high-intensity focused ultrasound (HIFU). PATIENTS AND METHODS: This observational cohort study used linked National Cancer Registry data, radiotherapy data, administrative hospital data and mortality records of 1381 men treated with HIFU for clinically localised prostate cancer in England. The primary outcome, FFS, was defined as freedom from local salvage treatment and cancer-specific mortality. Secondary outcomes were freedom from repeat HIFU, prostate cancer-specific survival (CSS) and overall survival (OS). Cox regression was used to determine whether baseline characteristics, including age, treatment year, T stage and International Society of Urological Pathology (ISUP) Grade Group were associated with FFS. RESULTS: The median (interquartile range [IQR]) follow-up was 37 (20-62) months. The median (IQR) age was 65 (59-70) years and 81% had an ISUP Grade Group of 1-2. The FFS was 96.5% (95% confidence interval [CI] 95.4%-97.4%) at 1 year, 86.0% (95% CI 83.7%-87.9%) at 3 years and 77.5% (95% CI 74.4%-80.3%) at 5 years. The 5-year FFS for ISUP Grade Groups 1-5 was 82.9%, 76.6%, 72.2%, 52.3% and 30.8%, respectively (P < 0.001). Freedom from repeat HIFU was 79.1% (95% CI 75.7%-82.1%), CSS was 98.8% (95% CI 97.7%-99.4%) and OS was 95.9% (95% CI 94.2%-97.1%) at 5 years. CONCLUSION: Four in five men were free from local salvage treatment at 5 years but treatment failure varied significantly according to ISUP Grade Group. Patients should be appropriately informed with respect to salvage radical treatment following HIFU.
RESUMO
OBJECTIVE: Rates of prenatal cannabis use are rising, yet little is known about modes of cannabis use during pregnancy. This focus group study with pregnant individuals aimed to examine use patterns and perceptions regarding common modes of prenatal cannabis use. METHOD: Kaiser Permanente Northern California pregnant adult patients who identified as White or Black and self-reported cannabis use during pregnancy were recruited to participate (N = 53; 40% Black, 60% White; Meanage = 30.3, SD = 5.2). Eighteen focus groups with race-concordant facilitators followed a semi-structured format that queried participants on their prenatal cannabis use, including preferred modes of use (e.g., vapes, blunts, dabs, joints, edibles, topicals, pipes). Focus group discussions were coded and analyzed using a general inductive approach. RESULTS: A range of modes were preferred, with no single mode predominant. Participants' preferences aligned with four themes: perceived effects and benefits of cannabis, health and safety, convenience and familiarity, and partner and friend influences. Participants sought modes that were accessible and familiar, provided consistent and quick relief for pregnancy-related symptoms, were aligned with partners or friends, and minimized perceived risks while also providing symptom relief. Participants desired evidence-based information about mode safety to better inform mode selection during pregnancy. CONCLUSIONS: A range of personal and social factors influenced mode preferences during pregnancy. Many participants desired to reduce harms and use cannabis more safely in pregnancy but received little mode-specific information to guide these preferences. Further research identifying mode-specific risks is needed to guide harm reduction approaches during pregnancy.

OBJECTIVES: Estimating cardiac risk is important for preoperative evaluation, and several risk calculators incorporate the American Society of Anesthesiologists (ASA) physical status score. The purpose of this study was to determine the concordance of ASA scores assigned by general internists and anesthesiologists and assess whether discrepancies affected cardiac risk estimation. METHODS: This observational study included military veterans evaluated in a preoperative evaluation clinic at a single center during a 12-month period. ASA scores were recorded by General Internal Medicine residents under the supervision of a General Internal Medicine attending, performing a preoperative medical consultation, and were compared with ASA scores assigned by an anesthesiologist on the day of surgery. ASA scores and Gupta Cardiac Risk Scores incorporating each ASA score were compared. RESULTS: Data were collected on 206 patients, 163 of whom had surgery within 90 days and were included. ASA scores were concordant in 60 patients (37.3%), whereas the ASA scores were rated lower by the general internist in 101 (62.0%) and higher in 2 (1.2%). Interrater reliability was low (κ = 0.08), and general internist scores were significantly lower than anesthesiologist scores (P < 0.01). Gupta Cardiac Risk Scores were calculated for 160 patients, and they exceeded 1% in 14 patients using the anesthesiologist ASA score, compared with 5 patients using the general internist score. CONCLUSIONS: ASA scores assigned by general internists in this study were significantly lower than those assigned by anesthesiologists, and these discrepancies in the ASA score can lead to substantially different conclusions about cardiac risk.

Introduction: Quantitative studies indicate that the COVID-19 pandemic has contributed to increased rates of prenatal cannabis use. However, little is known about how the pandemic has impacted cannabis use from the perspective of pregnant individuals themselves. Our objective was to characterize COVID-19-related changes in cannabis use among pregnant individuals who used cannabis during the pandemic. Methods: We conducted 18 focus groups (from 11/17/2021 to 12/17/2021) with Black and White pregnant individuals aged 18+ who self-reported prenatal cannabis use during universal screening at entrance to prenatal care (at ~8 weeks gestation) in Kaiser Permanente Northern California. Virtual focus groups were transcribed and analyzed using thematic analysis. Results: The sample of 53 pregnant individuals (23 Black, 30 White) was 30.3 years old (SD = 5.2) on average, and most (70%) self-reported daily versus weekly or monthly prenatal cannabis use. Major themes regarding the impact of the pandemic on cannabis use included increases in use (resulting from depression, anxiety, stress, boredom), and changes in social use (less sharing of smoked cannabis products), modes of use (from smoking to other modes due to respiratory concerns) and source (from storefront retailers to delivery). Conclusion: Coping with mental health symptoms and stress were identified drivers of perceived pandemic-related increases in prenatal cannabis use in 2021. Pregnant individuals adapted their use in ways consistent with public health recommendations to decrease social contact and reduce or quit smoking to mitigate COVID-19 transmission and harms. Proactive, mental health outreach for pregnant individuals during future pandemic waves may reduce prenatal cannabis use.
RESUMO
Purpose There is debate about the effectiveness and toxicity of pelvic lymph node (PLN) irradiation in addition to prostate bed radiotherapy when used to treat disease recurrence following radical prostatectomy. We compared toxicity from radiation therapy (RT) to the prostate bed and pelvic lymph nodes (PBPLN-RT) with prostatebed only radiation therapy (PBO-RT) following radical prostatectomy. Methods and Materials Patients with prostate cancer who underwent post-prostatectomy RT between 2010 and 2016 were identified by using the National Prostate Cancer Audit (NPCA) database. Follow-up data was available up to December 31, 2018. Validated outcome measures, based on a framework of procedural and diagnostic codes, were used to capture ≥Grade 2 gastrointestinal (GI) and genitourinary (GU) toxicity. An adjusted competing-risks regression analysis estimated subdistribution hazard ratios (sHR). A sHR > 1 indicated a higher incidence of toxicity with PBPLN-RT than with PBO-RT. Results 5-year cumulative incidences in the PBO-RT (n = 5,087) and PBPLNRT (n = 593) groups was 18.2% and 15.9% for GI toxicity, respectively. For GU toxicity it was 19.1% and 20.7%, respectively. There was no evidence of difference in GI or GU toxicity after adjustment between PBO-RT and PBPLN-RT (GI: adjusted sHR, 0.90, 95% CI, 0.67-1.19; P = 0.45); (GU: adjusted sHR, 1.19, 95% CI, 0.99-1.44; P = 0.09). Conclusions This national population-based study found that including PLNs in the radiation field following radical prostatectomy is not associated with a significant increase in rates of ≥Grade 2 GI or GU toxicity at 5 years.
RESUMO
INTRODUCTION: Enhanced recovery programs (ERPs) reduce racial disparities in surgical outcomes for general colorectal surgery populations. It is unclear, however, if disparities in IBD populations are impacted by ERPs. METHODS: Retrospective study comparing IBD patients undergoing major elective colorectal operations before (2006-2014) and after (2015-2021) ERP implementation using ACS-NSQIP data. The primary outcome of length of stay (LOS) was analyzed by negative binomial regression, and secondary outcomes (complications and readmissions) by logistic regression. RESULTS: Of 466 IBD patients, 47% were pre-ERP and 53% were ERP patients. In multivariable analysis stratified by ERP period, Black race was associated with increased odds of complications in the pre-ERP (OR 3.6, 95%CI 1.4-9.3) and ERP groups (OR 3.1 95%CI 1.3-7.6). Race was not a predictor of LOS or readmission in either group. High social vulnerability was associated with increased odds of readmission pre-ERP (OR 15.1, 95%CI 2.1-136.3), but this disparity was mitigated under ERPs (OR 1.4, 95%CI 0.4-5.6). CONCLUSION: While ERPs mitigated some disparities by social vulnerability, racial disparities persist in IBD populations even under ERPs. Further work is needed to achieve surgical equity for IBD patients.

BACKGROUND: Prolonged postoperative opioid use (PPOU) is considered an unfavorable post-surgical outcome. Demographic, clinical, and psychosocial factors have been associated with PPOU, but methods to prospectively identify patients at increased risk are lacking. OBJECTIVES: Our objective was to determine whether an individual or a combination of several psychological factors could identify a subset of patients at increased risk for PPOU. STUDY DESIGN: Observational cohort study with prospective baseline data collection and passive outcomes data collection. SETTING: A single VA medical center in the United States. METHODS: Patients were recruited from a preoperative anesthesia clinic where they were undergoing evaluation prior to elective surgery, and they completed a survey before surgery. The primary outcome was PPOU, defined as outpatient receipt of a prescribed opioid 31 to 90 days after surgery as determined from pharmacy records. Primary covariates of interest were pain catastrophizing, self-efficacy, and optimism. Additional covariates included social and demographic factors, pain severity, medication use, depression, anxiety, and surgical fear. RESULTS: Of 123 patients included in the final analyses, 30 (24.4%) had PPOU. In bivariate analyses, preoperative opioid use and preoperative nonsteroidal anti-inflammatory drug use were significantly associated with PPOU. The combination of high pain catastrophizing and high preoperative pain (OR 3.32, 95% CI 1.41 - 7.79) was associated with higher odds of PPOU than either alone, and the association remained significant after adjusting for preoperative opioid use (OR 2.56, 95% CI 1.04 - 6.29). LIMITATIONS: Patients were recruited from a single site, and the sample was not large enough to include potentially important variables such as procedure type. CONCLUSIONS: A combination of high pain catastrophizing and high preoperative pain has the potential to be a clinically useful means of identifying patients at elevated risk of PPOU.

OBJECTIVE: To determine the association of patient-level characteristics on the use of a patient engagement technology during the perioperative period. SUMMARY OF BACKGROUND DATA: As implementation of patient engagement technologies continues to grow, it remains unclear who uses, and not uses, these technologies. Existing literature suggests significant disparities in usage of other technologies by patient age, race, sex, and geographic location, however, have yet to characterize patient usage of patient engagement technologies. METHODS: This is a retrospective cohort study of patients undergoing elective surgery by a colorectal surgeon between January 2018 and March 2020 who enrolled in a patient engagement technology at a single institution. Patients enrolled received educational content, healthcare reminders, patient reported outcome (PRO) surveys, and health checks preoperatively, in-hospital, and for 30-days postdischarge. The primary outcome was patient activation of the patient engagement technology. Secondary outcomes were completion of at least 1 PRO survey, 1 in-hospital health check, and 1 postdischarge health check. RESULTS: Of 549 patients who enrolled in the patient engagement technology, 473 (86.2%) activated. On multivariable stepwise regression, female patients [odds ratio (OR) 2.4, confidence interval (CI) 1.4-4.0, P = 0.001] and privately insured patients (OR 2.0, CI 1.1-3.8, P = 0.03) were more likely to activate. Black patients were less likely to activate (OR 0.5, CI 0.3-0.9, P = 0.02). Once activated, privately insured patients were more likely to complete PRO surveys (OR 2.3, CI 1.2-4.3, P = 0.01), in-hospital health checks (OR 2.4, CI 1.4-4.1, P = 0.002), and postdischarge health checks (OR 1.9, CI 1.1 -3.3, P < 0.001) than uninsured patients. Black patients were less likely to complete PRO surveys (OR 0.4, CI 0.3-0.7, P = 0.001) and in-hospital health checks (OR 0.6, CI 0.4-0.9, P = 0.03) than White patients. CONCLUSIONS: Use of a patient engagement technology in the perioperative period differs significantly by sex, race/ethnicity, and insurance status. These technologies may not be used equally by all patients, which should be considered during implementation of interventions to improve surgical outcomes.

BACKGROUND/PURPOSE: This is an article submitted on behalf of the Canadian Association of Pediatric Surgeons. We assert that Pediatric Surgeons must work to dismantle systemic racism. Pediatric Surgeons have expertise in both common and rare surgical diseases affecting patients ranging from premature neonates to adolescents. Thus, our professional obligation is to transform our health and social systems to prevent the harms of racism to our patients. METHODS: Specific to the Canadian context, we describe a brief history, the ongoing impact on individuals and communities, and the harmful effect on the surgical community and trainees. Finally, we developed a series of practical recommendations to help surgeons become actively anti-racist. RESULTS: Four primary recommendations are made: (1) Increasing and supporting anti-racism education; (2) Changing individual behaviours to combat racism; (3) Developing strategies for organizational change; and (4) Committing to diversity in leadership. CONCLUSION: As surgeons, we are actors of change, and we can take meaningful steps to combat racism in our health systems. LEVEL OF EVIDENCE: V.

OBJECTIVE: The relationship between prostate-specific antigen (PSA) and prostate cancer (PCa) grade was traditionally thought to be linear but recent reports suggest this is not true in high-grade cancers. We aimed to compare the association between PSA and PCa-specific mortality (PCSM) in clinically localised low/intermediate and high-grade PCa. SUBJECTS/PATIENTS AND METHODS: Retrospective cohort study using the National Prostate Cancer Audit database in England of men treated with external beam radiotherapy (EBRT), EBRT and brachytherapy boost (EBRT + BT), radical prostatectomy or no radical local treatment between 2014 and 2018. Multivariable competing-risk regression was used to examine the association between PSA, Gleason, and PCSM. Multivariable restricted cubic spline regression was used to explore the non-linear associations of PSA and PCSM. RESULTS: 102,089 men were included, of whom 71,138 had low/intermediate-grade and 22,425 had high-grade PCa. In high-grade, 4-year PCSM was higher with PSA ≤5 than PSA 5.1-10 for men treated with EBRT (hazard ratio 1.96 (95% confidence interval 1.15-3.34) or no radical local treatment (hazard ratio 1.99 (95% confidence interval 1.33-2.98). Restricted cubic spline regression showed that PSA and PCSM have a non-linear association in high-grade but a linear association in low/intermediate-grade PCa. CONCLUSION: The low-PSA/high-grade combination in M0 PCa treated with EBRT has a higher PCSM than those with high-grade and intermediate PSA levels. In high-grade disease, the PSA association was non-linear; by contrast, low/intermediate-grade had a linear relationship. This confirms a more aggressive biology in low PSA secreting high-grade PCa and a worse outcome following treatment.

PURPOSE: Treatment with any adjuvant chemotherapy for stage III colon cancer has been shown to differ between population groups. Few studies, however, explore variations in the type of adjuvant chemotherapy received, none of which are from the UK. The aim of this study is to explore variation in the type of chemotherapy received by stage III colon cancer patients in England. METHODS: Data from the national cancer registry was linked to the Systemic Anti-Cancer Therapy database, which provides detailed information on treatment of malignant diseases from all NHS England chemotherapy providers. Demographic and clinical characteristics were compared between those who received monotherapy (fluoropyrimidine) or combination chemotherapy (fluoropyrimidine and oxaliplatin) among stage III colon cancer patients between 2012 and 2017. RESULTS: Of 8750 patients who received adjuvant chemotherapy, 22.3% (n = 2359) received monotherapy and 60.4% (n = 6391) received combination therapy. The odds of receiving combination therapy decreased with age. Those from the most deprived group had half the odds (OR: 0.5, CI: 0.42, 0.59, p < 0.001) of receiving combination therapy compared to the least deprived group. Women were 14% less likely to get combined therapy (OR: 0.86, CI: 0.77, 0.95, p = 0.005). Those with the largest tumour size (T4) and those with more than three lymph nodes involved (N2) had 30% (OR: 1.30; CI: 1.07, 1.59; p = 0.008) and 50% (OR: 1.50; 1.34, 1.69; p < 0.001) higher odds of receiving combination therapy compared to T1 or T2 and N1, respectively. CONCLUSION: There is variation in the type of chemotherapy received for stage III colon cancer patients by sociodemographic factors, despite clear clinical guidelines.

INTRODUCTION: The treatment of prostate cancer varies between the United States (US) and England, however this has not been well characterised using recent data. We therefore investigated the extent of the differences between US and English patients with respect to initial treatment. METHODS: We used the Surveillance, Epidemiology, and End Results (SEER) database to identify men diagnosed with prostate cancer in the US and the treatments they received. We also used the National Prostate Cancer Audit (NPCA) database for the same purposes among men diagnosed with prostate cancer in England. Next, we used multivariable regression to estimate the adjusted risk ratio (aRR) of receiving radical local treatment for men with non-metastatic prostate cancer according to the country of diagnosis (US vs. England). The five-tiered Cambridge Prognostic Group (CPG) classification was included as an interaction term. RESULTS: We identified 109,697 patients from the SEER database, and 74,393 patients from the NPCA database, who were newly diagnosed with non-metastatic prostate cancer between April 1st 2014 and December 31st 2016 with sufficient information for risk stratification according to the CPG classification. Men in the US were more likely to receive radical local treatment across all prognostic groups compared to men in England (% radical treatment US vs. England, CPG1: 38.1% vs. 14.3% - aRR 2.57, 95% CI 2.47-2.68; CPG2: 68.6% vs. 52.6% - aRR 1.27, 95% CI 1.25-1.29; CPG3: 76.7% vs. 67.1% - aRR 1.12, 95% CI 1.10-1.13; CPG4: 82.6% vs. 72.4% - aRR 1.09, 95% CI 1.08-1.10; CPG5: 78.2% vs. 71.7% - aRR 1.06, 95% CI 1.04-1.07) CONCLUSIONS: Treatment rates were higher in the US compared to England raising potential over-treatment concerns for low-risk disease (CPG1) in the US and under-treatment of clinically significant disease (CPG3-5) in England.
