RESUMEN
OBJECTIVE: To examine the association of anesthesiologist sex on postoperative outcomes. BACKGROUND: Differences in patient postoperative outcomes exist, depending on whether the primary surgeon is male or female, with better outcomes seen among patients treated by female surgeons. Whether the intraoperative anesthesiologist's sex is associated with differential postoperative patient outcomes is unknown. METHODS: We performed a population-based, retrospective cohort study among adult patients undergoing one of 25 common elective or emergent surgical procedures from 2007 to 2019 in Ontario, Canada. We assessed the association between the sex of the intraoperative anesthesiologist and the primary end point of the adverse postoperative outcome, defined as death, readmission, or complication within 30 days after surgery, using generalized estimating equations. RESULTS: Among 1,165,711 patients treated by 3006 surgeons and 1477 anesthesiologists, 311,822 (26.7%) received care from a female anesthesiologist and 853,889 (73.3%) from a male anesthesiologist. Overall, 10.8% of patients experienced one or more adverse postoperative outcomes, of whom 1.1% died. Multivariable adjusted rates of the composite primary end point were higher among patients treated by male anesthesiologists (10.6%) compared with female anesthesiologists (10.4%; adjusted odds ratio 1.02, 95% CI: 1.00-1.05, P =0.048). CONCLUSIONS: We demonstrated a significant association between sex of the intraoperative anesthesiologist and patient short-term outcomes after surgery in a large cohort study. This study supports the growing literature of improved patient outcomes among female practitioners. The underlying mechanisms of why outcomes differ between male and female physicians remain elusive and require further in-depth study.

PURPOSE: Neoadjuvant chemotherapy (NAC) for triple-negative (TN) and Her2-positive (HER2) breast cancers is supported by international guidelines as it can decrease extent of surgery, provide prognostic information, and allow response-driven adjuvant therapies. Our goal was to describe practice patterns for patients with TN and HER2-positive breast cancer and identify the factors associated with the receipt of NAC versus surgery as initial treatment. METHODS: A retrospective population-based cohort study of adult women diagnosed with stage I-III TN or HER2-positive breast cancer (2012-2020) in Ontario was completed using linked administrative datasets. The primary outcome was NAC as first treatment. The association between NAC and patient, tumor, and practice-related factors was examined using multivariable logistic regression models. RESULTS: Of 14,653 patients included, 23.9% (n = 3500) underwent NAC as first treatment. Patients who underwent NAC were more likely to be younger and have larger tumors, node-positive disease, and stage 3 disease. Of patients who underwent surgery first, 8.8% were seen by a medical oncologist prior to surgery. On multivariable analysis, increasing tumor size (T2 vs T1/T0: 2.75 (2.31-3.28)) and node-positive (N1 vs N0: OR 3.54 (2.92-4.30)) disease were both associated increased odds of receiving NAC. CONCLUSION: A considerable proportion of patients with TN and HER2-positive breast cancer do not receive NAC as first treatment. Of those, most were not assessed by both a surgeon and medical oncologist prior to initiating therapy. This points toward potential gaps in multidisciplinary assessment and disparities in receipt of guideline-concordant care.

IMPORTANCE: Collecting patient-reported outcomes (PROs) in routine cancer care improves patient-clinician communication, decision making, and overall patient satisfaction. Recommendations exist regarding standardized ways to collect, store, and interpret PRO data. However, evidence on incorporating PROs into cancer process of care, especially the type of HIs that are warranted after observing a concerning PRO and the effectiveness of these HIs are lacking. OBJECTIVE: This study summarizes HIs triggered after PRO completion and their effectiveness in improving patient outcomes for adults being treated for cancer types that are resource intensive and associated with high symptom burden [i.e., gastrointestinal (GI), lung, and head and neck cancer (HNC)]. Secondary outcomes included factors associated with poor implementation of PROs. EVIDENCE REVIEW: A literature search of peer-reviewed publications on MEDLINE, CINAHL Plus, APA PsycInfo, Scopus, and Cochrane was conducted following PRISMA guidelines from 1 January 2012, to 31 July 2022. Trial and real-world studies describing HIs after PRO completion for adult patients being treated for GI, lung, and HNC were included. Sixteen studies involving 144,496 patients were included. The Joanna Briggs Institute critical appraisal checklist was used to assess risk of bias. FINDINGS: Of the 16 included studies, 5 included patients with HNC. Commonly used PRO measurement tools were the PRO-CTCAE and ESAS. Only three studies reported specific HIs delivered in response to concerning PROs and measured their effectiveness on patient outcomes. In all three studies, these HIs significantly improved cancer-related care. The most common HIs undertaken in response to concerning PROs were referrals to other specialists/allied healthcare professionals, medication changes, or self-management advice. Provider-related barriers to PRO measurement and delivery included the overwhelming number of alerts, the time required to address each PRO and the unclear role of healthcare providers in response to these alerts. Patient-related barriers included lower digital literacy and socioeconomic status, older age, rural living, and patients suffering from GI and HNC. CONCLUSIONS AND RELEVANCE: This review highlights that PRO-triggered HIs are heterogenous and can improve patient quality of life. Further studies are necessary to determine the types of interventions with the greatest impact on patient care and outcomes.

BACKGROUND: Comparative studies evaluating quality of care in different healthcare systems can guide reform initiatives. This study seeks to characterize best practices by comparing utilization and outcomes for patients with pancreatic cancer (PC) in the USA and Ontario, Canada. METHODS: Patients (age ≥ 66 years) with PC were identified from the Ontario Cancer Registry and SEER-Medicare databases from 2006 to 2015. Demographics and treatment (surgery, radiation, chemotherapy, or multimodality (surgery and chemotherapy)) were described. In resected patients, neoadjuvant therapy, readmission, and 30- and 90-day postoperative mortality rates were calculated. Survival was assessed using Kaplan-Meier curves. RESULTS: This study includes 38,858 and 11,512 patients with PC from the USA and Ontario, respectively. More female patients were identified in the USA (54.0%) versus Ontario (46.9%). In the entire cohort, US patients received more radiation in addition to other therapies (18.8% vs. 13.5% Ontario) and chemotherapy alone (34.3% vs. 19.0% Ontario). While rates of resection were similar (13.4% USA vs.12.5% Ontario), multimodality therapy was more common in the UAS (9.0% vs. 6.4%). Among resected patients, neoadjuvant chemotherapy was uncommon in both groups, although more frequent in the USA (12.0% vs. 3.2% Ontario). The 30- and 90-day postoperative mortality rates were lower in Ontario vs. the USA (30-day: 3.26% vs. 4.91%; 90-day: 7.08% vs. 10.96%), however, overall survival was similar between the USA and Ontario. CONCLUSIONS: We observed substantive differences in treatment and outcomes between PC patients in the USA and Ontario, which may reflect known differences in healthcare systems. Close evaluation of healthcare policies can inform initiatives to improve care quality.

BACKGROUND: Team diversity is recognized not only as an equity issue but also a catalyst for improved performance through diversity in knowledge and practices. However, team diversity data in healthcare are limited and it is not known whether it may affect outcomes in surgery. This study examined the association between anaesthesia-surgery team sex diversity and postoperative outcomes. METHODS: This was a population-based retrospective cohort study of adults undergoing major inpatient procedures between 2009 and 2019. The exposure was the hospital percentage of female anaesthetists and surgeons in the year of surgery. The outcome was 90-day major morbidity. Restricted cubic splines were used to identify a clinically meaningful dichotomization of team sex diversity, with over 35% female anaesthetists and surgeons representing higher diversity. The association with outcomes was examined using multivariable logistic regression. RESULTS: Of 709 899 index operations performed at 88 hospitals, 90-day major morbidity occurred in 14.4%. The median proportion of female anaesthetists and surgeons was 28 (interquartile range 25-31)% per hospital per year. Care in hospitals with higher sex diversity (over 35% female) was associated with reduced odds of 90-day major morbidity (OR 0.97, 95% c.i. 0.95 to 0.99; P = 0.02) after adjustment. The magnitude of this association was greater for patients treated by female anaesthetists (OR 0.92, 0.88 to 0.97; P = 0.002) and female surgeons (OR 0.83, 0.76 to 0.90; P < 0.001). CONCLUSION: Care in hospitals with greater anaesthesia-surgery team sex diversity was associated with better postoperative outcomes. Care in a hospital reaching a critical mass with over 35% female anaesthetists and surgeons, representing higher team sex-diversity, was associated with a 3% lower odds of 90-day major morbidity.

PURPOSE: Patients with lung cancer can experience significant psychological morbidities including depression. We characterize patterns and factors associated with interventions for symptoms of depression in stage IV non-small cell lung cancer (NSCLC). METHODS: We conducted a population-based cohort study using health services administrative data in Ontario, Canada of stage IV NSCLC diagnosed from January 2007 to September 2018. A positive symptom of depression score was defined by reporting at least one ESAS (Edmonton Symptom Assessment System) depression score ≥ 2 following diagnosis until the end of follow-up (September 2019). Patient factors included age, sex, comorbidity burden, rurality of residence, and neighbourhood income quintile. Interventions included psychiatry assessment, psychology referral, social work referral and anti-depressant medical therapy (for patients ≥ 65 years with universal drug coverage). Multivariable modified Poisson regression models were used to examine the association between patient factors and intervention use for patients who reported symptoms of depression. RESULTS: In the cohort of 13,159 patients with stage IV NSCLC lung cancer, symptoms of depression were prevalent (71.4%, n = 9,397). Patients who reported symptoms of depression were more likely to receive psychiatry assessment/psychology referral (7.8% vs 3.5%; SD [standardized difference] 0.19), social work referral (17.4% vs 11.9%; SD 0.16) and anti-depressant prescriptions (23.8% vs 13.8%; SD 0.26) when compared to patients who did not report symptoms of depression respectively. In multivariable analyses, older patients were less likely to receive any intervention. Females were more likely to obtain a psychiatry assessment/psychology referral or social work referral. In addition, patients from non-major urban or rural residences were less likely to receive psychiatry assessment/psychology referral or social work referral, however patients from rural residences were more likely to be prescribed anti-depressants. CONCLUSIONS: There is high prevalence of symptoms of depression in stage IV NSCLC. We identify patient populations, including older patients and rural patients, who are less likely to receive interventions that will help identifying and screening for symptoms of depression.

Importance: Tranexamic acid reduces bleeding and blood transfusion in many types of surgery, but its effect in patients undergoing liver resection for a cancer-related indication remains unclear. Objective: To determine whether tranexamic acid reduces red blood cell transfusion within 7 days of liver resection. Design, Setting, and Participants: Multicenter randomized clinical trial of tranexamic acid vs placebo conducted from December 1, 2014, to November 8, 2022, at 10 hepatopancreaticobiliary sites in Canada and 1 site in the United States, with 90-day follow-up. Participants, clinicians, and data collectors were blinded to allocation. A volunteer sample of 1384 patients undergoing liver resection for a cancer-related indication met eligibility criteria and consented to randomization. Interventions: Tranexamic acid (1-g bolus followed by 1-g infusion over 8 hours; n = 619) or matching placebo (n = 626) beginning at induction of anesthesia. Main Outcomes and Measures: The primary outcome was receipt of red blood cell transfusion within 7 days of surgery. Results: The primary analysis included 1245 participants (mean age, 63.2 years; 39.8% female; 56.1% with a diagnosis of colorectal liver metastases). Perioperative characteristics were similar between groups. Red blood cell transfusion occurred in 16.3% of participants (n = 101) in the tranexamic acid group and 14.5% (n = 91) in the placebo group (odds ratio, 1.15 [95% CI, 0.84-1.56]; P = .38; absolute difference, 2% [95% CI, -2% to 6%]). Measured intraoperative blood loss (tranexamic acid, 817.3 mL; placebo, 836.7 mL; P = .75) and total estimated blood loss over 7 days (tranexamic acid, 1504.0 mL; placebo, 1551.2 mL; P = .38) were similar between groups. Participants receiving tranexamic acid experienced significantly more complications compared with placebo (odds ratio, 1.28 [95% CI, 1.02-1.60]; P = .03), with no significant difference in venous thromboembolism (odds ratio, 1.68 [95% CI, 0.95-3.07]; P = .08). Conclusions and Relevance: Among patients undergoing liver resection for a cancer-related indication, tranexamic acid did not reduce bleeding or blood transfusion but increased perioperative complications. Trial Registration: ClinicalTrials.gov Identifier: NCT02261415.
RESUMEN
We explored perspectives of patients with metastatic non-small cell lung cancer (mNSCLC) on symptom screening and population-level patient-reported outcome (PRO) data regarding common symptom trajectories in the year after diagnosis. A qualitative study of patients with mNSCLC was conducted at a Canadian tertiary cancer centre. English-speaking patients diagnosed ≥ 6 months prior to study invitation were recruited, and semi-structured one-on-one interviews were conducted. Patient and treatment characteristics were obtained via chart review. Anonymized interview transcripts underwent deductive-inductive coding and thematic content analysis. Among ten participants (5 (50%) females; median (range) age, 68 (56-77) years; median (range) time since diagnosis, 28.5 (6-72) months; 6 (60%) with smoking histories), six themes were identified in total. Two themes were identified regarding symptom screening: (1) screening is useful for symptom self-monitoring and disclosure to the healthcare team, (2) screening of additional quality-of-life (QOL) domains (smoking-related stigma, sexual dysfunction, and financial toxicity) is desired. Four themes were identified regarding population-level symptom trajectory PRO data: (1) data provide reassurance and motivation to engage in symptom self-management, (2) data should be disclosed after an oncologic treatment plan is developed, (3) data should be communicated via in-person discussion with accompanying patient-education resources, and (4) communication of data should include reassurance about symptom stabilization, acknowledgement of variability in patient experience, and strategies for symptom self-management. The themes and recommendations derived from the patient experience with mNSCLC provide guidance for enhanced symptom screening and utilization of population-level symptom trajectory data for patient education.

BACKGROUND: Approximately 15% of patients experience post-hepatectomy liver failure after major hepatectomy. Poor hepatocyte uptake of gadoxetate disodium, a magnetic resonance imaging contrast agent, may be a predictor of post-hepatectomy liver failure. METHODS: A retrospective cohort study of patients undergoing major hepatectomy (≥3 segments) with a preoperative gadoxetate disodium-enhanced magnetic resonance imaging was conducted. The liver signal intensity (standardized to the spleen) and the functional liver remnant was calculated to determine if this can predict post-hepatectomy liver failure after major hepatectomy. RESULTS: In 134 patients, low signal intensity of the remnant liver standardized by signal intensity of the spleen in post-contrast images was associated with post-hepatectomy liver failure in multiple logistic regression analysis (Odds Ratio 0.112; 95% CI 0.023-0.551). In a subgroup of 33 patients with lower quartile of functional liver remnant, area under the curve analysis demonstrated a diagnostic accuracy of functional liver remnant to predict post-hepatectomy liver failure of 0.857 with a cut-off value for functional liver remnant of 1.4985 with 80.0% sensitivity and 89.3% specificity. CONCLUSION: Functional liver remnant determined by gadoxetate disodium-enhanced magnetic resonance imaging is a predictor of post-hepatectomy liver failure which may help identify patients for resection, reducing morbidity and mortality.

OBJECTIVE: To examine the long-term healthcare dependency outcomes of older adults undergoing VATS compared to open lung cancer resection. SUMMARY OF BACKGROUND DATA: Although the benefits of VATS for lung cancer resection have been reported, there is a knowledge gap related to long-term functional outcomes central to decision-making for older adults. METHODS: We conducted a population-based retrospective comparative cohort study of patients ≥70 years old undergoing lung cancer resection between 2010 and 2017 using linked administrative health databases. VATS was compared to open surgery for lung cancer resection. Outcomes were receipt of homecare and high time-at-home, defined as <14 institution-days within 1 year, in 5 years after surgery. We used time-to-event analyses. Homecare was analyzed as recurrent dichotomous outcome with Andersen-Gill multivariable models, and high time-at-home with Cox multivariable models. RESULTS: Of 4974 patients, 2951 had VATS (59.3%). In the first three months postoperatively, homecare use ranged from 17.5% to 34.4% for VATS and 23.0% to 36.6% for open surgery. VATS was independently associated with lower need for postoperative homecare over 5 years (hazard ratio 0.82, 95% confidence interval 0.74-0.92). 1- and 5-year probability of high "time-at-home" were superior for VATS (74.4% vs 66.7% and 55.6% vs 45.4%, p < 0.001). VATS was independently associated with higher probability of high "time-at-home" (hazard ratio 0.81, 95% confidence interval 0.74-0.89) compared to open surgery. CONCLUSIONS: Compared to open surgery, VATS was associated with lower homecare needs and higher probability of high "time-at-home," indicating reduced long-term functional dependence. Those important patient-centered endpoints reflect the overall long-term treatment burden on mortality and morbidity that can inform surgical decision-making.

OBJECTIVE: To examine long-term healthcare dependency outcomes of stereotactic body radiation therapy (SBRT) to surgery for older adults with stage I non-small cell lung cancer (NSCLC). BACKGROUND: SBRT is an emerging alternative to surgery in patients with early-stage lung cancer. There remains a paucity of prospective studies comparing these modalities, especially with respect to long-term dependency outcomes in older adults with lung cancer. METHODS: Adults 70 years old and above with stage I NSCLC treated with surgery or SBRT from January 2010 to December 2017 were analyzed using 1:1 propensity score matching. Homecare use, days at home, and time spent alive and at home were compared. E-value methods assessed residual confounding. RESULTS: A total of 1129 and 2570 patients underwent SBRT and surgery, respectively. In all, 1016 per group were matched. SBRT was associated with a higher overall risk of homecare utilization [hazard ratio (HR)=1.75, 95% confidence interval (CI): 1.37-2.23] than surgery up to 5 years following treatment. While the hazards of death or nursing home admission were lower in the first 3 months after SBRT (HR=0.55, 95% CI: 0.36-0.85), they became consistently higher beyond this period and remained high up to 5 years compared with surgery (HR=2.13; 95% CI: 1.85-2.45). The above findings persisted in stratified analyses for frail patients and those with no pretreatment homecare. E-values indicated it was unlikely that the observed estimates could be explained by unmeasured confounders. CONCLUSIONS: Surgery offers robust long-term dependency outcomes compared with SBRT. These are important patient-centered endpoints which may be used for counseling and shared decision-making in older adults with stage I NSCLC.

OBJECTIVE: We sought to compare long-term healthcare dependency and time-at-home between older adults undergoing minimally invasive surgery (MIS) for colorectal cancer (CRC) and those undergoing open resection. BACKGROUND: Although the benefits of MIS for CRC resection are established, data specific to older adults are lacking. Long-term functional outcomes, central to decision-making in the care for older adults, are unknown. METHODS: We performed a population-based analysis of patients ≥70years old undergoing CRC resection between 2007 to 2017 using administrative datasets. Outcomes were receipt of homecare and "high" time-at-home, which we defined as years with ≤14 institution-days, in the 5years after surgery. Homecare was analyzed using time-to-event analyses as a recurrent dichotomous outcome with Andersen-Gill multivariable models. High timeat-home was assessed using Cox multivariable models. RESULTS: Of 16,479 included patients with median follow-up of 4.3 (interquartile range 2.1-7.1) years, 7822 had MIS (47.5%). The MIS group had lower homecare use than the open group with 22.3% versus 31.6% at 6 months and 14.8% versus 19.4% at 1 year [hazard ratio 0.87,95% confidence interval (CI) 0.83-0.92]. The MIS group had higher probability ofhigh time-at-home than open surgery with 54.9% (95% CI 53.6%-56.1%) versus 41.2% (95% CI 40.1%-42.3%) at 5years (hazard ratio 0.71, 95% CI 0.68-0.75). CONCLUSIONS: Compared to open surgery, MIS for CRC resection was associated with lower homecare needs and higher probability of high time-at-home in the 5 years after surgery, indicating reduced long-term functional dependence. These are important patient-centered endpoints reflecting the overall long-term treatment burden to be taken into consideration in decision-making.

OBJECTIVE: To conduct a population-level analysis of temporal trends and risk factors for high symptom burden in patients receiving surgery for non-small cell lung cancer (NSCLC). BACKGROUND: A population-level overview of symptoms after curative intent surgery is necessary to inform decision making and supportive care for patients with lung cancer. METHODS: Retrospective cohort study of patients receiving surgery for stages I to III NSCLC between January 2007 and September 2018. Prospectively collection Edmonton Symptom Assessment System (ESAS) scores, linked to provincial administrative data, were used to describe the prevalence, trajectory, and predictors of moderate-to-severe symptoms in the year following surgery. RESULTS: A total of 5350 patients, with 28,490 unique ESAS assessments, were included in the analysis. Moderate-to-severe tiredness (68%), poor wellbeing (63%), and shortness of breath (60%) were the most common symptoms reported. The rise and fall in the proportion of patients experiencing moderate-to-severe symptoms after surgery coincided with the median time to first (58 days, interquartile range: 47-72) and last cycle of chemotherapy (140 days, interquartile range: 118-168), respectively. There was eventual stabilization, albeit above the preoperative baseline, within 6 to 7 months after surgery. Female sex (relative risk [RR] 1.09- 1.26), lower income (RR 1.08-1.23), stage III disease (RR 1.15-1.43), adjuvant therapy (RR 1.09-1.42), chemotherapy within 2 weeks of an ESAS assessment (RR 1.14-1.73), and pneumonectomy (RR 1.05-1.15) were associated with moderate-to-severe symptoms following surgery. CONCLUSIONS: Knowledge of population-level prevalence, trajectory, and predictors of moderate-to-severe symptoms after surgery for NSCLC can be used to facilitate shared decision making and improve symptom management throughout the course of illness.

OBJECTIVE: To examine the association of between hospital rates of high-volume anesthesiology care and of postoperative major morbidity. BACKGROUND: Individual anesthesiology volume has been associated with individual patient outcomes for complex gastrointestinal cancer surgery. However, whether hospital-level anesthesiology care, where changes can be made, influences the outcomes of patients cared at this hospital is unknown. METHODS: We conducted a population-based retrospective cohort study of adults undergoing esophagectomy, pancreatectomy, or hepatectomy for cancer from 2007 to 2018. The exposure was hospital-level adjusted rate of high-volume anesthesiology care. The outcome was hospital-level adjusted rate of 90-day major morbidity (Clavien-Dindo grade 3-5). Scatterplots visualized the relationship between each hospital's adjusted rates of high-volume anesthesiology and major morbidity. Analyses at the hospital-year level examined the association with multivariable Poisson regression. RESULTS: For 7893 patients at 17 hospitals, the rates of high-volume anesthesiology varied from 0% to 87.6%, and of major morbidity from 38.2% to 45.4%. The scatter plot revealed a weak inverse relationship between hospital rates of high-volume anesthesiology and of major morbidity (Pearson: -0.23). The adjusted hospital rate of high-volume anesthesiology was independently associated with the adjusted hospital rate of major morbidity (rate ratio: 0.96; 95% CI, 0.95-0.98; P <0.001 for each 10% increase in the high-volume rate). CONCLUSIONS: Hospitals that provided high-volume anesthesiology care to a higher proportion of patients were associated with lower rates of 90-day major morbidity. For each additional 10% patients receiving care by a high-volume anesthesiologist at a given hospital, there was an associated reduction of 4% in that hospital's rate of major morbidity.

OBJECTIVE: Examine between-hospital and between-anesthesiologist variation in anesthesiology provider-volume (PV) and delivery of high-volume anesthesiology care. BACKGROUND: Better outcomes for anesthesiologists with higher PV of complex gastrointestinal cancer surgery have been reported. The factors linking anesthesiology practice and organization to volume are unknown. METHODS: We identified patients undergoing elective esophagectomy, hepatectomy, and pancreatectomy using linked administrative health data sets (2007-2018). Anesthesiology PV was the annual number of procedures done by the primary anesthesiologist in the 2 years before the index surgery. High-volume anesthesiology was PV>6 procedures/year. Funnel plots to described variation in anesthesiology PV and delivery of high-volume care. Hierarchical regression models examined between-anesthesiologist and between-hospital variation in delivery of high-volume care use with variance partition coefficients (VPCs) and median odds ratios (MORs). RESULTS: Among 7893 patients cared for at 17 hospitals, funnel plots showed variation in anesthesiology PV (median ranging from 1.5, interquartile range: 1-2 to 11.5, interquartile range: 8-16) and delivery of HV care (ranging from 0% to 87%) across hospitals. After adjustment, 32% (VPC 0.32) and 16% (VPC: 0.16) of the variation were attributable to between-anesthesiologist and between-hospital differences, respectively. This translated to an anesthesiologist MOR of 4.81 (95% CI, 3.27-10.3) and hospital MOR of 3.04 (95% CI, 2.14-7.77). CONCLUSIONS: Substantial variation in anesthesiology PV and delivery of high-volume anesthesiology care existed across hospitals. The anesthesiologist and the hospital were key determinants of the variation in high-volume anesthesiology care delivery. This suggests that targeting anesthesiology structures of care could reduce variation and improve delivery of high-volume anesthesiology care.

BACKGROUND: Curative intent cancer treatment needs to be balanced with patient comorbidities and quality of life when treating older women with breast cancer. We examined consultation patterns and association of age at diagnosis with lack of specialist cancer consultations for older women with breast cancer. METHODS: We conducted a population-based retrospective cohort study of older women (≥ 70 years of age) with incident, non-metastatic breast cancer (2010-2018) by linking administrative databases in Ontario, Canada. The outcomes of interest were lack of specialist cancer consultation (surgeon, medical oncology, or radiation oncology) within 12 months of diagnosis. Association of age with lack of specialist cancer consultation was examined using Poisson regression modeling. RESULTS: Of 21,849 older women, 2.4% (n = 517) did not have any specialist cancer consultation within 12 months of diagnosis; lack of any specialist cancer consultation increased with age (0.8% for age 70-74 years, 1.3% for age 75-79 years, 2.5% for age 80-84 years, and 7.0% for age ≥ 85 years; p < 0.001). The proportion of patients who did not have consultations with surgeons, medical oncologists, and radiation oncologists was 8.6% (n = 1888), 34.4% (n = 7510), and 24.7% (n = 5404), respectively. Older age group was independently associated with an increased likelihood of lacking any specialist consultation, as well as not receiving surgical and medical oncology consultations. CONCLUSION: More than one-third of women ≥ 70 years of age with non-metastatic breast cancer did not have a consultation with a medical oncologist, with women aged ≥ 85 years least likely to have a medical oncology consultation.

BACKGROUND: Older adults have unique needs for supportive care after surgery. We examined symptom trajectories and factors associated with high symptom burden after cancer surgery in older adults. PATIENTS AND METHODS: We conducted a population-level study of patients ≥ 70 years old undergoing cancer surgery (2007-2018) using prospectively collected Edmonton Symptom Assessment System (ESAS) scores. The monthly prevalence of moderate to severe symptoms (ESAS ≥ 4) for anxiety, depression, drowsiness, lack of appetite, nausea, pain, shortness of breath, tiredness, and poor wellbeing was computed over 12 months after surgery. RESULTS: Among 48,748 patients, 234,420 ESAS scores were recorded over 12 months after surgery. Moderate to severe tiredness (57.8%), poor wellbeing (51.9%), and lack of appetite (39.3%) were most common. The proportion of patients with moderate to severe symptoms was stable over the 1 month prior to and 12 months after surgery (< 5% variation for each symptom). There was no clinically significant change (< 5%) in symptom trajectory with the initiation of adjuvant therapy. CONCLUSIONS: Patient-reported symptom burden was stable for up to 1 year after cancer surgery among older adults. Neither surgery nor adjuvant therapy coincided with a worsening in symptom burden. However, the persistence of symptoms at 1 year may suggest gaps in supportive care for older adults. This information on symptom trajectory and predictors of high symptom burden is important to set appropriate expectations and improve patient counseling, recovery care pathways, and proactive symptom management for older adults after cancer surgery.

INTRODUCTION: Cancer symptom screening has the potential to improve cancer outcomes, including reducing symptom burden among patients with major mental illness (MMI). We determined rates of symptom screening with the Edmonton Symptom Assessment System (ESAS-r) and risk of severe symptoms in cancer patients with MMI. METHODS: This retrospective cohort study used linked administrative health databases of adults diagnosed with cancer between 2007 and 2020. An MMI was measured in the 5 years prior to cancer diagnosis and categorized as inpatient, outpatient, or no MMI. Outcomes were defined as time to first ESAS-r screening and time to first moderate-to-severe symptom score. Cause-specific and Fine and Gray competing events models were used for both outcomes, controlling for age, sex, rural residence, year of diagnosis and cancer site. RESULTS: Of 389,870 cancer patients, 4049 (1.0%) had an inpatient MMI and 9775 (2.5%) had an outpatient MMI. Individuals with inpatient MMI were least likely to complete an ESAS-r (67.5%) compared to those with outpatient MMI (72.3%) and without MMI (74.8%). Compared to those without MMI, individuals with an inpatient or outpatient MMI had a lower incidence of symptom screening records after accounting for the competing risk of death (subdistribution Hazard Ratio 0.77 (95% CI 0.74-0.80) and 0.88 (95% CI 0.86-0.90) respectively). Individuals with inpatient and outpatient MMI status consistently had a significantly higher risk of reporting high symptom scores across all symptoms. CONCLUSIONS: Understanding the disparity in ESAS-r screening and management for cancer patients with MMI is a vital step toward providing equitable cancer care.
RESUMEN
BACKGROUND: Older adults are at high-risk for a post-operative intensive care unit (ICU) admission, yet little is known about the impact of these admissions on quality of life. The objective of this study was to evaluate the impact of an unexpected post-operative ICU admission on the burden of cancer symptoms among older adults who underwent high-intensity cancer surgery and survived to hospital discharge. METHODS: We performed a population-based cohort study of older adults (age ≥ 70) who underwent high-intensity cancer surgery and survived to hospital discharge in Ontario, Canada (2007-2017). Using the Edmonton Symptom Assessment System (ESAS), a standardized tool that quantifies patient-reported physical, mental, and emotional symptoms, we described the burden of cancer symptoms during the year after surgery. Total symptom scores ≥ 40 indicated a moderate-to-severe symptom burden. Modified log-Poisson analysis was used to estimate the impact of an unexpected post-operative ICU admission (admission not related to routine monitoring) on the likelihood of experiencing a moderate-to-severe symptom burden during the year after surgery, accounting for potential confounders. We then used multivariable generalized linear mixed models to model symptom trajectories among patients with two or more ESAS assessments. A 10-point difference in total symptom scores was considered clinically significant. RESULTS: Among 16,560 patients (mean age 76.5 years; 43.4% female), 1,503 (9.1%) had an unexpected ICU admission. After accounting for baseline characteristics, patients with an unexcepted ICU admission were more likely to experience a moderate-to-severe symptom burden relative to those without an unexpected ICU admission (RR 1.64, 95% CI 1.31-2.05). Specifically, among patients with an unexcepted ICU admission the average probability of experiencing moderate-to-severe symptoms ranged from 6.9% (95 CI 5.8-8.3%) during the first month after surgery to 3.2% (95% CI 0.9-11.7%) at the end of the year. Among the 11,229 (67.8%) patients with multiple ESAS assessments, adjusted differences in total scores between patients with and without an unexpected ICU admission ranged from 2.0 to 5.7-points throughout the year (p < 0.001). CONCLUSION: While unexpected ICU admissions are associated with a small increase in the likelihood of experiencing a moderate-to-severe symptom burden, most patients do not experience a high overall symptom burden during the year after surgery. These findings support the role of aggressive therapy among older adults after major surgery.

BACKGROUND: Pancreaticoduodenectomy is the only curative option for patients with pancreatic cancer; however, pain remains a considerable problem postoperatively. With many centres moving away from using epidural analgesia, there is the need to evaluate alternative opiate sparing techniques for postoperative analgesia. We sought to determine if rectus sheath catheters (RSCs) had an opiate sparing and analgesic effect compared with standard care alone (opiate analgesia). METHODS: We conducted a retrospective pre- and postintervention cohort study of patients undergoing pancreaticoduodenectomy at a single tertiary academic hospital in Toronto, Canada, between April 2018 and December 2019. All patients undergoing a pancreaticoduodenectomy were eligible for inclusion. Among the 101 patients identified, 84 (61 control, 23 RSCs) were analyzed after exclusion criteria were applied (epidural analgesia, admission to intensive care intubated or reintubated within the first 96 hours). The pre-intervention group received a semi-standardized course of analgesics, including intravenous hydromorphone, acetaminophen, ketamine, with or without nonsteroidal anti-inflammatory, and with or without intravenous lidocaine; the latter 2 drugs were at the individual anesthesiologist and surgeon's preference. For the postintervention group, the same course of analgesics were used, with the addition of RSCs. These were inserted at the end of the operation, with a loading dose of ropivacaine administered and followed by a programmed intermittent bolus regime for 72-96 hours. The primary outcome measure was total postoperative opiate consumption (oral morphine equivalents). Secondary outcomes included pain scores (numeric rating scale) and treatment-related adverse effects. RESULTS: Opiate consumption (oral morphine equivalents) at 96 hours was significantly lower (median 188 mg, interquartile range [IQR] 112-228 v. 242.4 mg, IQR 166.8-352) with and without RSC, respectively (p = 0.01). The RSC group used significantly less opiates at each time point from 24 hours postoperatively, with no significant difference in pain scores between the groups and no significant catheter-related complications. CONCLUSION: The use of RSCs was associated with significant reductions in postoperative opiate consumption. Given the ease of placement and management, with minimal complications, RSCs should be incorporated into a course of postoperative multimodal analgesia. A large scale randomized controlled trial should be conducted to further investigate these findings.
