Abstract 4143258: Sex Differences in Health Status Outcomes: Analysis of the ISCHEMIA Randomized Clinical Trial

Background: Despite a lesser extent and severity of coronary artery disease (CAD), women had a higher burden of angina than men in the ISCHEMIA trial, suggesting that other factors may explain symptom severity in women. We aim to describe demographic and clinical characteristics, as well as differences in care patterns, associated with health status differences in women, as compared with men, in the conservative and invasive treatment groups of the ISCHEMIA trial. Methods: The ISCHEMIA trial randomized participants with moderate or severe ischemia to a routine invasive strategy of cardiac catheterization with complete revascularization plus guideline-directed medical therapy (GDMT), or an initial conservative strategy of GDMT alone with catheterization reserved for GDMT failure. Health status was a key secondary outcome. Using linear regression models we compared raw and adjusted Seattle Angina Questionnaire (SAQ) scores in women and men at baseline and at 1 year, stratified by randomized treatment strategy. Within the invasive strategy, sex differences were adjusted for completeness of revascularization among those with ≥1 coronary stenosis ≥70%. Results: Of 4,617 ISCHEMIA participants with valid SAQ data, women had lower (worse) baseline SAQ summary scores (SS) throughout follow up (Figure) after adjustment for demographics and clinical characteristics, including severity of CAD (difference 5.4 points, 95% CI 4.0-6.7). Women had lower SAQ SS after adjustment for post-randomization treatment (i.e., medical therapy, achievement of risk factor goals and, in the invasive strategy, complete revascularization), 2.4 points lower (95% CI 0.7-4.1) in the conservative group (Figure), and 1.9 points lower than in men (95% CI 0.1-3.7) in the invasive group. Findings were similar for all SAQ subscales. Conclusions: Women with chronic coronary disease in ISCHEMIA had worse health status than men at baseline and 1 year later, which was not explained by demographic or clinical characteristics, intensity of medical therapy, or completeness of revascularization.

Care Patterns and Outcomes for Intrahepatic Cholangiocarcinoma by Rurality of Patient Residence in a Midwestern State.

Intrahepatic cholangiocarcinoma (ICC) is the second most common malignancy of the liver and has the worst prognosis of any tumor arising from the liver, with a 5-year survival as low as 10%. However, whether the rurality of a patient's residence impacts care received and survival has not been well studied. We aimed to assess differences in care patterns associated with the rurality of patient's residences and their impact on survival outcomes, hypothesizing that patients in rural areas would experience lower survival. Adult patients diagnosed with ICC between 2010 and 2020 were identified in the Iowa Cancer Registry. Chi-square tests were used to compare values categorical variables by rural/urban status. Cox proportional hazards regression was used to determine associations with cancer-specific mortality. Of 672 patients diagnosed with ICC during the study period, 53%, 27%, and 21% resided in metropolitan, micropolitan, and rural areas, respectively. There were no significant differences in age, sex, stage at diagnosis, the proportion receiving chemotherapy within 12 weeks of diagnosis, and undergoing surgery across all groups. Additionally, the proportion receiving definitive care at a National Cancer Institute (NCI) designated center was comparable across the three groups (37% metro vs. 43% micro vs. 35% rural). However, rural residents had the highest proportion of traveling ≥ 50 miles for definitive care (22% metro vs. 41% micro vs. 56% rural). In multivariable analysis of patients with Stage 1-3 disease, younger age, receipt of chemotherapy, surgery, and definitive care at an NCI center were independently associated with decreased mortality risk. However, rural residence was not significantly associated with survival (HR: 0.64 [95% CI: 0.38-1.06]). Similar to other complex cancer diagnoses, we found that definitive care at an NCI center was associated with decreased mortality risk for patients with ICC. Although rural residence was not independently associated with survival in this cohort, rural residents traveled significantly longer distances to access definitive care. This highlights a crucial need to improve access to specialized centers for complex cancer care.

Differences in Health Care and Palliative Care Use at the End of Life: A Comparison Study Among Lung Cancer, COPD, and Idiopathic Pulmonary Fibrosis

Patients with lung cancer, idiopathic pulmonary fibrosis (IPF), and chronic obstructive pulmonary disease (COPD) have high symptom burden, poor quality of life, and high healthcare utilization at the end of life. While proactive integration of palliative care in lung cancer can improve outcomes, it is unclear whether similar practices have been adopted in COPD and IPF care. Do patients with COPD and IPF have different patterns of healthcare and palliative care use at the end of life compared to lung cancer? We retrospectively identified deceased patients with lung cancer, COPD, or IPF with ≥1 outpatient visit at [removed] in the last six months of life. We compared outpatient palliative care and opioid prescriptions, inpatient palliative care, hospitalizations, intensive care use, and in-hospital death in the last 6 months of life between each group. We used multivariable logistic regression to calculate adjusted odds ratios of each outcome, with lung cancer as the reference group. Among 1,819 patients, patients with COPD and IPF were more likely to be male and older at the time of death, compared to patients with lung cancer. Compared to lung cancer, patients with COPD and IPF had a lower adjusted odds (p<0.001) of receiving outpatient palliative care (aOR COPD: 0.26, 95% CI: 0.19-0.36; aOR IPF: 0.48, 95% CI: 0.32-0.70), outpatient opioids (aOR COPD: 0.50, 95% CI: 0.40-0.63; aOR IPF: 0.40, 95% CI: 0.29-0.54), and a higher odds of end-of-life ICU use (COPD aOR: 2.88, 95% CI: 2.11-3.93; IPF aOR: 4.15, 95% CI: 2.66-6.49). Patients with IPF had higher odds of receiving inpatient palliative care (aOR: 2.02, 95% CI: 1.30-3.13, p=0.002). Patients with COPD and IPF are less likely to receive outpatient palliative care and opioid prescriptions and more likely to use end-of-life intensive care than patients with lung cancer. Further research should explore health system barriers contributing to differences in care patterns to optimize quality of life and align with patient goals of care.

Different Patterns of Care and Survival Outcomes in Transplant-Centre Managed Patients with Early-Stage HCC: Real-World Data from an Australian Multi-Centre Cohort Study.

The management of early-stage hepatocellular carcinoma (HCC) is complex, with multiple treatment strategies available. There is a paucity of literature regarding variations in the patterns of care and outcomes between transplant and non-transplant centres. We conducted this real-world multi-centre cohort study in two liver cancer referral centres with an integrated liver transplant program and an additional eight non-transplant HCC referral centres across Australia to identify variation in patterns of care and key survival outcomes. Patients with stage Barcelona Clinic Liver Cancer (BCLC) 0/A HCC, first diagnosed between 1 January 2016 and 31 December 2020, who were managed at a participating site, were included in the study. Patients were excluded if they had a history of prior HCC or if they received upfront liver transplantation. A total of 887 patients were included in the study, with 433 patients managed at a liver cancer centre with a transplant program (LTC) and 454 patients managed at a non-transplant centre (NTC). Management at an LTC did not significantly predict allocation to resection (adjusted OR 0.75, 95% CI 0.50 to 1.11, p = 0.148). However, in those not receiving resection, LTC and NTC patients were systematically managed differently, with LTC patients five times less likely to receive upfront ablation than NTC patients (adjusted OR 0.19, 95% CI 0.13 to 0.28, p < 0.001), even after adjusting for tumour burden, as well as for age, gender, liver disease aetiology, liver disease severity, and medical comorbidities. LTCs exhibited significantly higher proportions of patients undergoing TACE for every tumour burden category, including those with a single tumour measuring 2 cm or less (p < 0.001). Using multivariable Cox proportional hazards analysis, management at a transplant centre was associated with reduced all-cause mortality (adjusted HR 0.71, 95% CI 0.51 to 0.98, p = 0.036), and competing-risk regression analysis, considering liver transplant as a competing event, demonstrated a similar reduction in risk (adjusted HR 0.70, 95% CI 0.50 to 0.99, p = 0.041), suggesting that the reduced risk of death is not fully explained by higher rates of transplantation. Our study highlights systematic differences in HCC care between large volume liver transplant centres and other sites, which has not previously been well-described. Further work is needed to better define the reasons for differences in treatment allocation and to aim to minimise unwarranted treatment variation to maximise patient outcomes across Australia.

Differences in end-of-life care patterns between types of hospice used for cancer patients: a retrospective cohort study.

In response to the rapid aging population and increasing number of cancer patients, discussions on dignified end-of-life (EoL) decisions are active around the world. Therefore, this study aimed to identify the differences in EoL care patterns between types of hospice used for cancer patients. In this population-based cohort study, the Korean National Health Insurance Service cohort data containing all registered cancer patients who died between 2017 and 2021 were used. A total of 408,964 individuals were eligible for analysis. The variable of interest, the type of hospice used in the 6months before death, was classified as follows: (1) Non-hospice users; (2) Hospital-based hospice single users; (3) Home-based hospice single users; (4) Combined hospice users. The outcomes were set as patterns of care, including intense care and supportive care. To identify differences in care patterns between hospice types, a generalized linear model with zero-inflated negative binomial distribution was applied. Hospice enrollment was associated with less intense care and more supportive care near death. Notably, those who used combined hospice care had the lowest probability and frequency of receiving intense care (aOR: 0.18, 95% CI: 0.17-0.19, aRR: 0.47, 95% CI: 0.44-0.49), while home-based hospice single users had the highest probability and frequency of receiving supportive care (Prescription for narcotic analgesics, aOR: 2.95, 95% CI: 2.69-3.23, aRR: 1.45, 95% CI: 1.41-1.49; Mental health care, aOR: 3.40, 95% CI: 3.13-3.69, aRR: 1.35, 95% CI: 1.31-1.39). Our findings suggest that although intense care for life-sustaining decreases with hospice enrollment, QoL at the EoL actually improves with appropriate supportive care. This study is meaningful in that it not only offers valuable insight into hospice care for terminally ill patients, but also provides policy implications for the introduction of patient-centered community-based hospice services.

Differences in Patterns of Care and Referral Between Proton and Photon Therapy

PurposeTo report demographic and clinical characteristics of patients who were more likely to receive proton beam therapy (PBT) than photon therapy from facilities with access to proton centers. Materials and MethodsWe utilized the national cancer database to identify the facilities with access to PBT between 2004 and 2015 and compared the relative usage of photons and PBT for demographic and clinical scenarios in breast, prostate, and nonsmall cell cancer. ResultsIn total, 231 facilities with access to proton centers accounted for 168 323 breast, 39 975 lung, and 77 297 prostate cancer patients treated definitively. Proton beam therapy was used in 0.5%, 1.5%, and 8.9% of breast, lung, and prostate cases. Proton beam therapy was correlated with a farther distance traveled and longer start time from diagnosis for each site (P < .05).For breast, demographic correlates of PBT were treatment in the west coast (odds ratio [OR] = 4.81), age <60 (OR = 1.25), white race (OR = 1.94), and metropolitan area (OR = 1.58). Left-sided cancers (OR = 1.28), N2 (OR = 1.71), non-ER+/PR+/Her2Neu− cancers (OR = 1.24), accelerated partial breast irradiation (OR = 1.98), and hypofractionation (OR = 2.35) were predictors of PBT.For nonsmall cell cancer, demographic correlates of PBT were treatment in the south (OR = 2.6), metropolitan area (OR = 1.72), and Medicare insurance (OR = 1.64). Higher comorbid score (OR = 1.36), later year treated (OR = 3.16), and hypofractionation (not SBRT) (OR = 3.7) were predictors of PBT.For prostate, correlates of PBT were treatment in the west coast (OR = 2.48), age <70 (OR = 1.19), white race (OR = 1.41), metropolitan area (OR = 1.25), higher income/education (OR = 1.25), and treatment at an academic center (OR = 33.94). Lower comorbidity score (OR = 1.42), later year treated (OR = 1.37), low-risk disease (OR = 1.45), definitive compared to postoperative (OR = 6.10), and conventional fractionation (OR = 1.64) were predictors of PBT. ConclusionEven for facilities with established referrals to proton centers, PBT utilization was low; socioeconomic status was potentially a factor. Proton beam therapy was more often used with left-sided breast and low-risk prostate cancers, without a clear clinical pattern in lung cancer.

Differences in Primary Care Management of Patients With Adult Attention Deficit Hyperactivity Disorder (ADHD) Based on Race and Ethnicity

Objective: Examine differences in care patterns around adult ADHD between race (White/Non-White) and ethnic (Hispanic/Non-Hispanic) groups utilizing existing quality measures (QMs), concerning diagnosis, treatment, and medication prescribing. Methods: The AAFP National Research Network in partnership with SUNY Upstate Medical used an EHR dataset to evaluate achievement of 10 ADHD QMs. The dataset was obtained from DARTNet Institute and includes 4 million patients of 873 behavioral and primary care practices with at least 100 patients from 2010 to 2020. Patients 18-years or older with adult ADHD were included in this analysis. Results: White patients and Non-Hispanic/Latinx patients were more likely to achieve these QMs than Non-White patients and Hispanic/Latinx patients, respectively. Differences between groups concerning medication and monitoring demonstrate a disparity for Non-White and Hispanic/Latinx populations. Conclusions: Using QMs in EHR data can help identify gaps in ADHD research. There is a need to continue investigating disparities of quality adult ADHD care.

Economic Hardship at the End of Life for Families of Children With Complex Chronic Conditions

ContextMany children with complex chronic medical conditions (CCC), though living longer, die prematurely. Little is known about family economic hardship during end of life (EOL), nor associated differences in patterns of care. ObjectivesTo describe the prevalence, experience, and characteristics of families of patients with CCC who report great economic hardship (GEH), and associations with end-of-life care patterns and suffering. MethodsWe conducted a 183-item cross-sectional survey of bereaved parents of patients cared for at Boston Children's Hospital and chart reviews for each patient. Fifteen survey items on economic hardship related to financial and material hardships including food, housing, and utility insecurity. ResultsA total of 114 bereaved parents completed the survey (54% response rate) and economic hardship data was analyzed for 105. Nearly a fifth reported GEH. This group was characterized by fewer two parent households. Children from families with GEH had spent more time hospitalized than those without GEH. ConclusionEconomic burden on families of children with CCC correlates with higher health care utilization demonstrating the need for ameliorative resources and preventative measures.

Effects of season length and uniparental care efficacy on the evolution of parental care.

Parental care patterns differ enormously among and even within species. This is exemplified by Chinese penduline tits Remiz consobrinus, where biparental care, female-only care, male-only care and biparental desertion all occur in the same population; moreover, the distribution of these care patterns differs systematically between populations. The eco-evolutionary determinants of this diversity are largely unknown. We developed an individual-based model that allows us to investigate the effects of season length and offspring needs (expressed by the efficacy with which a clutch can be raised by a single parent) on the evolution of parental care patterns. The model is largely conceptual, aiming at general conclusions. However, to keep the model realistic, its set-up and the choice of parameters are motivated by field studies on Chinese penduline tits. Exploring a wide range of parameters, we investigate how parental care patterns are affected by season length and offspring needs and whether and under what conditions diverse parental care patterns can stably coexist. We report five main findings. First, under a broad range of conditions, different care patterns (e.g. male care and biparental care) coexist at equilibrium. Second, for the same parameters, alternative evolutionary equilibria are possible; this can explain differences in care patterns across populations. Third, rapid evolutionary transitions can occur between alternative equilibria; this can explain the often-reported evolutionary lability of parental care patterns. Fourth, season length has a strong but nonmonotonic effect on the evolved care patterns. Fifth, when uniparental care efficacy is low, biparental care tends to evolve; however, in many scenarios uniparental care is still common at equilibrium. In addition, our study sheds new light on Trivers' hypothesis that the sex with the highest prezygotic investment is predestined to invest more postzygotically as well. Our study highlights that diversity in parental care can readily evolve and it shows that even in the absence of environmental change parental care patterns can be evolutionary labile. In the presence of directional environmental change, systematic shifts in care patterns are to be expected.

Patterns of mental health care provision in urban areas: A comparative analysis for local policy in the ACT.

Urbanisation presents specific mental health challenges, requiring a better understanding of service availability in urban areas for mental health care planning. Our objective is to analyse patterns of urban mental healthcare provision in Australia, and compare these with relevant national and international regions to inform urban mental healthcare policy and planning. Following a health ecosystems approach, we use a standardised service classification instrument, the Description and Evaluation of Services and DirectoriEs (DESDE), and Mental Health Care Atlases, to compare the availability, bed capacity and diversity of services providing specialised mental health or psychosocial care that are universally accessible (ie provided at no or low cost only in all relevant care sectors in four Australian and three international urban regions. We used a heuristics approach and an homogeneity test. Applicability to local policy was assessed using the Adoption Impact Ladder. Community care was less developed in Australia than internationally, except in the case of residential care in Australian Capital Territory, our reference area. Alternatives to hospitalisation were scarce across all regions. The Atlas was applicable to regional and local mental health planning. Differences in pattern of care between regions has implications for planning, equality of access to care and prioritisation of resources. An ecosystems approach is relevant to service planning in mental healthcare at local level.

Association of Hospice Profit Status With Family Caregivers’ Reported Care Experiences

Expansive growth in the US hospice market has been driven almost exclusively by an increase in for-profit hospices. Prior research found that, in contrast to not-for-profit hospices, for-profit hospices focus on delivering care to patients in nursing homes, provide fewer nursing visits, and use less skilled staff. However, prior studies have not reported on the associations of these differences in care patterns with hospice care quality. Patient- and family-centeredness is a core element of hospice care quality that is measured through surveys of care experiences. To examine whether differences in profit status are associated with family caregivers' reports of hospice care experiences and assess factors that may be associated with observed differences in care experiences by profit status. Consumer Assessment of Healthcare Providers and Systems (CAHPS) Hospice Survey data from 653 208 caregiver respondents, reflecting care received from 3107 hospices between April 2017 and March 2019, were used for a cross-sectional examination of hospice care experiences by profit status. Data analysis was performed from January 2020 to November 2022. Outcomes were case-mix-adjusted and mode-adjusted top-box scores for 8 measures of hospice care experiences, including communication, timely care, symptom management, and emotional and religious support, as well as a summary score averaging across measures. Linear regression examined the association between profit status and hospice-level scores, adjusting for other organizational and structural hospice characteristics. There were 906 not-for-profit and 1761 for-profit hospices with mean (SD) time in operation of 25.7 (7.8) years and 13.8 (8.0) years, respectively. Mean (SD) decedent age at death was 82.8 (2.3) years, similar for not-for-profit and for-profit hospices. The mean proportion of patients who were Black, Hispanic, and White was 4.9%, 0.9%, and 91.4% for not-for-profit hospices and 9.0%, 2.2%, and 85.4% for for-profit hospices, respectively. Family caregivers reported worse care experiences at for-profit hospices than at not-for-profit hospices for all measures. Significant differences in average hospice performance by profit status remained after adjusting for hospice characteristics. However, for-profit hospice performance varied, with 548 of 1761 (31.1%) for-profit hospices scoring 3 or more points below the national hospice average of overall performance and 386 of 1761 (21.9%) scoring 3 or more points above the average. In contrast, only 113 of 906 (12.5%) not-for-profit hospices scored 3 or more points below the average, and 305 of 906 (33.7%) scored 3 or more points above the average. In this cross-sectional study of CAHPS Hospice Survey data, caregivers of patients receiving hospice care reported substantially worse care experiences in for-profit than in not-for-profit hospices; however, there was variation in reported experiences among both types of hospices. Public reporting of hospice quality is important.

Rates and Predictors of Surgery for Lumbar Disc Herniation Between the Military and Civilian Health Care Systems.

Retrospective review (level of evidence III). Surgical care patterns for lumbar disc herniation (LDH), a common musculoskeletal condition of high relevance to the Military Health System (MHS), have not been described or compared across the direct care and purchased care MHS components. This study aimed to describe surgery rates in MHS beneficiaries who were diagnosed with LDH in direct care versus purchased care and to evaluate characteristics associated with the location of surgery. Differences in care patterns for LDH may suggest unexpected variation within the centrally managed MHS. We described 1-year rates of surgery among beneficiaries who were diagnosed with LDH in direct care versus purchased care. Among beneficiaries who were diagnosed in direct care and had surgery, multivariable logistic regression models were used to identify characteristics associated with surgery location. We identified 726,638 MHS beneficiaries who were diagnosed with LDH in direct care or purchased care during the 9-year study period. One-year surgery rates were 10.1% in beneficiaries who were diagnosed in direct care versus 11.3% in beneficiaries who were diagnosed in purchased care. Among the 7467 patients who were diagnosed in direct care and had surgery within 1 year, characteristics associated with lower probability of surgery in purchased care versus direct care included diagnosing facility type (hospital with a neurosurgery or spine specialty versus clinic (odds ratio [OR], 0.12 (95% CI, 0.10-0.15)), Navy versus Army (OR, 0.24 (95% CI, 0.21-0.28)), and diagnosing facility specialty (Medical Expense and Performance Reporting System) (surgical care (OR, 0.33 (95% CI, 0.27-0.40)) and orthopedic care (OR, 0.39 (95% CI, 0.33-0.46)) versus primary care. The presence of comorbidities was associated with higher probability of surgery in purchased care versus direct care (OR, 1.20 (95% CI, 1.06-1.36)). The 1-year rate of surgery for LDH was modestly higher in beneficiaries who were diagnosed in purchased care versus direct care. Among patients who were diagnosed in direct care, several patient-level and facility-level characteristics were associated with receiving surgery in purchased care, suggesting potentially unexpected variation in care utilization across components of the MHS.

Exploring ethnic differences in post-discharge patterns of surgical care for older adults admitted with diverticulitis.

We aimed to evaluate ethnic differences in patterns of care following an index nonoperative admission for acute diverticulitis amongst a universally insured patient cohort. We identified nationwide Medicare beneficiaries aged 65.5 years or older hospitalized between 1 July 2015 and 1 November 2017 for nonoperative management of an index admission for diverticulitis. Patients were followed for 1 year to examine patterns of care. Primary categorical outcomes included receipt of an elective operation, emergency operation, nonoperative readmission or no further hospitalizations for diverticulitis. Multinomial regression was performed to determine the association between ethnicity and receipt of each primary outcome category whilst adjusting for potential confounders. We examined the use of percutaneous drainage during the index admission to better understand its association with subsequent care patterns. Amongst 22 630 study patients, subsequent operative treatment was less common for Black, Hispanic, Asian and American Indian patients relative to White patients. Multinomial logistic regression noted that Black (relative risk 0.40; 95% CI 0.32-0.50) and Asian (relative risk 0.37; 95% CI 0.15-0.91) patients were associated with the lowest relative risk of undergoing an elective interval operation compared to White patients. Black patients were also associated with a 1.43 (95% CI 1.19-1.73) increased risk of requiring subsequent nonoperative readmissions for disease recurrence compared to White patients. The use of percutaneous drainage was higher amongst White patients relative to Black patients (6.9% vs. 4.0%, P value < 0.001). We have identified ongoing inequities in the consumption of medical resources, with White patients being more likely to undergo elective colectomy and percutaneous drainage. Differences in care are not fully alleviated by equal access to insurance.

Outcomes and Management of Head and Neck Cancer at a South Indian Cancer Centre: A Retrospective Study

Abstract Introduction Head and neck cancers are one of the most common cancers in the Indian subcontinent. The trends of these cancers worldwide have drastically changed over the past 15 years. In spite of all the new technology and timely diagnosis, the treatment of these cancers is still a challenge. These cancers still continue to be a significant cause of morbidity and mortality worldwide. Objectives To identify different patterns of care received by patients with primary head and neck cancer in a single center and analyze the outcomes of the different patterns of care received by these patients in terms of overall survival and disease-free survival. Materials and Methods We included 707 patients with primary head and neck cancer registered and treated in our institution from January 2015 to December 2017. The demographic details of the patient, treatment received, and outcomes of treatment were collected retrospectively from our hospital's medical registry. Descriptive analysis was performed by calculating mean and standard deviation for quantitative variables, whereas frequency and proportion were calculated for categorical variables. The mean/median overall survival and recurrence-free survival were compared across various explanatory parameters using log rank–test. A p-value &lt; 0.05 was considered statistically significant. Results A total of 707 patients were included in the final analysis. The median age of presentation was 60 years. In total, 50% of patients presented with stage IV disease at diagnosis and 78% had a history of smoking or other tobacco use. Oral cavity was the most common primary site. Concurrent chemotherapy with radiation therapy was the most common modality of treatment used in 49% of patients: RT was the common modality of treatment in 21% patients. Fourteen percent patients were treated by only surgery. All patients who underwent treatment were included for survival analysis, which showed that the median overall survival time was 42 months (34–49 months). The median duration of disease free-survival time was 37 months (30–43 months). Conclusion In our study, most patients presented with locally advanced disease. Multimodality treatment yielded better results. Based on our study, in early-stage cancer, where single modality treatment was used, adjuvant therapy should be tailored based on nomogram.

969-P: Changes in Patterns of Care in Diabetes via Virtual Care Delivery Prior to and During COVID-Pandemic

Background: The COVID-pandemic and virtual care has impacted the care delivery of many health care conditions including diabetes. This study aimed to compare how patterns of care for diabetes have changed as a result of virtual care and the COVID-pandemic at a large academic ambulatory care facility in Toronto, Canada. Methods: Patients were included who had an initial diabetes visit between September 15, 20 and September 20, 2020. Fisher's exact test was used to determine differences in care patterns between visits pre and during COVID- (after March 14, 2020) . Results: Pre-COVID-19, there were 240 (72.7%) completed initial visits and 90 (27.3%) follow-up visits, including 27.5% and 36.7% for type 1 diabetes, respectively. During COVID-19, there were 235 (44.1%) initial visits and 298 (56%) follow-up visits including 29.4% and 27.2% for type 1 diabetes, respectively. Including all visits, there were more no-shows during COVID-19, 4.5% vs. 1.5%; p&amp;lt;0.05. Out of 330 pre-COVID-visits, all (100%) were done in-person. During COVID-19, out of 533 visits, 89.3% were done by phone, 7.5% by video, and only 3.2% in-person. Conclusion: During COVID-19, there were more follow-up diabetes visits seen compared to initial visits and more no-shows. Most diabetes visits were done by phone during COVID-19. More data is needed to understand how diabetes care delivery has changed as a result of virtual care during COVID-19. Disclosure P.Palcu: None. G.Mukerji: n/a. C.Chu: None. C.Pendrith: None.

Dissecting patterns of care in patients with variant histology of bladder cancer and lymph node invasion

Objectives Lymph node invasion (LNI) is related to long-term survival in patients with muscle-invasive bladder cancer. However, in the case of variant histology (VH), data on pelvic lymph node dissection (PLND) and LNI are sparse. We described the pattern of care of PLND in patients with VHs of bladder cancer, exploring predictors of LNI. Methods Using the 2001–2016 SEER registry, 20 767 bladder cancer patients who underwent PLND were identified. Included histological variants were pure urothelial carcinoma (UC), micropapillary UC, sarcomatoid UC, lymphoepithelioma-like UC, adenocarcinoma, sarcoma, giant and spindle cell carcinoma, squamous cell carcinoma (SCC), and neuroendocrine tumor. Uni- and multivariable logistic regression analyses tested for LNI predictors. Cox regression was used to test for predictors of overall mortality (OM) among both LNI positive and LNI negative patients. Results Overall, 2464 (11.9%) harbored a VH. On multivariate analysis, only micropapillary UC was associated with higher risk (OR = 3.39) of LNI. This association was maintained when only the subset of patients treated without perioperative chemotherapy were analyzed (OR = 3.30). Similarly, higher T stage (T2 stage OR = 2.24; T3–4 stage OR = 9.44) and the use of chemotherapy (OR = 2.29) were associated with a higher risk of LNI. Among patients with LNI (5299, 25.5%), SCC (HR = 1.87), T3–4 stage (HR = 1.94), age at diagnosis (HR = 1.01) and geographic region (south) (HR = 1.22) were predictors of higher risk of OM. Conversely, chemotherapy (HR = 0.69) and number of removed LN (HR = −0.99) were associated with lower risk of OM. Finally, in a subgroup of patients without LNI, sarcomatoid UC (HR = 1.58) and giant and spindle cell carcinoma (HR = 1.83) were the only VH predictors of OM. Conclusions We described different patterns of care in patients with VHs of bladder cancer. Micropapillary UC was an independent risk factor for LNI. Among patients harboring LNI, those with SCC VH had higher OM compared to pure UC. Conversely, sarcomatoid UC and giant and spindle cell carcinoma were predictors of OM in patients without nodal involvement.

PCN207 Retrospective Study of Acute Myeloid Leukemia and Myelodysplastic Syndrome Patients in a Single Hospital System

Acute Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS) are part of a group of hematological disorders with high risk of marrow failure and mortality. There is scarce real-world data about these cancer patients. We sought to evaluate differences in patterns of care between the AML and MDS populations at an NCI-designed center. A retrospective chart review was conducted on patients who were ≥ 18 years old, diagnosed with AML or MDS and treated between 06/01/2016 and 03/31/2020. Patients were excluded if they had acute promyelocytic leukemia, unknown race, or inadequate treatment time. Information collected for analysis included laboratory data, type of treatment, and demographics. Age, gender, race, smoking status, eastern cooperative oncology group (ECOG) status, AML cytogenetics risk, malignancies, survival and reception of bone marrow transplants, palliative care consults or chemotherapy inductions were variables that were assessed. Chi squared tests and ANOVA were used to compare categorical and continuous variables, respectively. Out of 129 patients, the mean age was 75 [SD 10.0], 66% were male, and 81% were white. Primary diagnosis was MDS in 58% and AML in 42% of the patients. Age, gender, race, smoking status, ECOG, malignancies and number of bone marrow transplants and palliative care consults were similar in both groups. Differences between AML and MDS patients were seen in cytogenetics risk category with an adverse risk (59% and 9.7%, respectively; p< 0.0001), in the number of chemotherapy inductions (67.3% and 43.1% had two cycles, respectively; p=0.008) and mean survival (459 days [SD 366] and 974 days [SD 1132], respectively; p=0.007). Significant differences exist between characteristics of the AML and MDS patient populations. Further research is warranted to assess the impact of these differences on healthcare costs and resource utilization.

Care Patterns and Overall Survival in Patients With Early-Onset Metastatic Colorectal Cancer.

Colorectal cancer (CRC) incidence in patients younger than 50 years of age, commonly defined as early-onset (EO-CRC), is rising. EO-CRC often presents with distinct clinicopathologic features. However, data on prognosis are conflicting and outcomes with modern treatment approaches for metastatic disease are still limited. We prospectively enrolled patients with metastatic CRC (mCRC) to a biobanking and clinical data collection protocol from 2014 to 2018. We grouped the cohort based on age at initial diagnosis: < 40 years, 40-49 years, and ≥ 50 years. We used regression models to examine associations among age at initial diagnosis, treatments, clinicopathologic features, and survival. We identified 466 patients with mCRC (45 [10%] age < 40 years, 109 [23%] age 40-49 years, and 312 [67%] age ≥ 50 years). Patients < 40 years of age were more likely to have received multiple metastatic resections (odds ratio [OR], 3.533; P = .0066) than their older counterparts. Patients with EO-CRC were more likely to receive triplet therapy than patients > 50 years of age (age < 40 years: OR, 6.738; P = .0002; age 40-49 years: OR, 2.949; P = .0166). Patients 40-49 years of age were more likely to have received anti-EGFR therapy (OR, 2.633; P = .0016). Despite differences in care patterns, age did not predict overall survival. Despite patients with EO-CRC receiving more intensive treatments, survival was similar to the older counterpart. However, EO-CRC had clinical and molecular features associated with worse prognoses. Improved biologic understanding is needed to optimize clinical management of EO-CRC. The cost-benefit ratio of exposing patients with EO-CRC to more intensive treatments has to be carefully evaluated.

Reperfusion Treatment and Stroke Outcomes in Hospitals With Telestroke Capacity

Telestroke is increasingly used in hospital emergency departments, but there has been limited research on its impact on treatment and outcomes. To describe differences in care patterns and outcomes among patients with acute ischemic stroke who present to hospitals with and without telestroke capacity. Patients with acute ischemic stroke who first presented to hospitals with telestroke capacity were matched with patients who presented to control hospitals without telestroke capacity. All traditional Medicare beneficiaries with a primary diagnosis of acute ischemic stroke (approximately 2.5 million) who presented to a hospital between January 2008 and June 2017 were considered. Matching was based on sociodemographic and clinical characteristics, hospital characteristics, and month and year of admission. Hospitals included short-term acute care and critical access hospitals in the US without local stroke expertise. In 643 hospitals with telestroke capacity, there were 76 636 patients with stroke who were matched 1:1 to patients at similar hospitals without telestroke capacity. Data were analyzed in July 2020. Receipt of reperfusion treatment through thrombolysis with alteplase or thrombectomy, mortality at 30 days from admission, spending through 90 days from admission, and functional status as measured by days spent living in the community after discharge. In the final sample of 153 272 patients, 88 386 (57.7%) were female, and the mean (SD) age was 78.8 (10.4) years. Patients cared for at telestroke hospitals had higher rates of reperfusion treatment compared with those cared for at control hospitals (6.8% vs 6.0%; difference, 0.78 percentage points; 95% CI, 0.54-1.03; P < .001) and lower 30-day mortality (13.1% vs 13.6%; difference, 0.50 percentage points; 95% CI, 0.17-0.83, P = .003). There were no differences in days spent living in the community following discharge or in spending. Increases in reperfusion treatment were largest in the lowest-volume hospitals, among rural residents, and among patients 85 years and older. Patients with ischemic stroke treated at hospitals with telestroke capacity were more likely to receive reperfusion treatment and have lower 30-day mortality.

Comparative analysis of emergency general surgery on-call structure and its impact on emergency appendicectomy outcomes.

In Australia, there has been a shift from the traditional 'on-call' surgical model to the 'acute surgical unit' (ASU) model to improve outcomes in acute general surgery. Using emergency appendicectomy as a standardized procedure, we aimed to identify the different patterns of care between these on-call structures by comparing two metropolitan district hospitals; one that employs a traditional on-call model and the other, which employ the ASU model. Data on consecutive patients undergoing emergency appendectomies at the two hospitals (traditional and ASU model) between July 2018 and December 2018 were retrieved for retrospective review. Patient factors, preoperative factors, operative factors and post-operative outcomes were collected and tabulated for comparative analysis between the traditional versus ASU model of care. Univariate analysis demonstrated that there were a greater proportion of consultant-led cases (P < 0.001), a shorter time to theatre (P = 0.047) and a greater number of out-of-hours operations (P < 0.001) in the ASU model compared to the traditional model. A larger proportion of patients from the traditional model underwent a computed tomography scan as part of their diagnostic workup compared to the ASU model (P < 0.001). There was no difference in negative appendicectomy rates, intraoperative conversion rates, post-operative complication rates or mean lengths of hospital stay between the two on-call models. The ASU and traditional on-call model appears to achieve equivalent care outcomes for patients with acute appendicitis.
