RESUMO
BACKGROUND: The objective of this study was to quantify disparities in cancer treatment delivery between minority-serving hospitals (MSHs) and non-MSHs for breast, prostate, nonsmall cell lung, and colon cancers from 2010 to 2019 and to estimate the impact of improving care at MSHs on national disparities. METHODS: Data from the National Cancer Database (2010-2019) identified patients who were eligible for definitive treatments for the specified cancers. Hospitals in the top decile by minority patient proportion were classified as MSHs. Multivariable logistic regression adjusted for patient and hospital characteristics compared the odds of receiving definitive treatment at MSHs versus non-MSHs. A simulation was used to estimate the increase in patients receiving definitive treatment if MSH care matched the levels of non-MSH care. RESULTS: Of 2,927,191 patients from 1330 hospitals, 9.3% were treated at MSHs. MSHs had significant lower odds of delivering definitive therapy across all cancer types (adjusted odds ratio: breast cancer, 0.83; prostate cancer, 0.69; nonsmall cell lung cancer, 0.73; colon cancer, 0.81). No site of care-race interaction was significant for any of the cancers (p > .05). Equalizing treatment rates at MSHs could result in 5719 additional patients receiving definitive treatment over 10 years. CONCLUSIONS: The current findings underscore systemic disparities in definitive cancer treatment delivery between MSHs and non-MSHs for breast, prostate, nonsmall cell lung, and colon cancers. Although targeted improvements at MSHs represent a critical step toward equity, this study highlights the need for integrated, system-wide efforts to address the multifaceted nature of racial and ethnic health disparities. Enhancing care at MSHs could serve as a pivotal strategy in a broader initiative to achieve health care equity for all.

PURPOSE: To evaluate how limited English proficiency (LEP) impacts the prevalence of prostate-specific antigen (PSA) screening in a contemporary, nationally representative cohort of men in the USA. METHODS: The Medical Expenditure Panel Survey was utilized to identify the prevalence of PSA screening between 2013 and 2016 among men ≥ 55. Men who speak a language other than English at home were stratified by self-reported levels of English proficiency (men who speak English very well, well, not well, or not at all). Survey weights were applied, and groups were compared using the adjusted Wald test. A multivariable logistic regression model was used to identify predictors of PSA screening adjusting for patient-level covariates. RESULTS: The cohort included 2,889 men, corresponding to a weighted estimate of 4,765,682 men. 79.6% of men who speak English very well reported receiving at least one lifetime PSA test versus 58.4% of men who do not speak English at all (p < 0.001). Men who reported not speaking English at all had significantly lower prevalence of PSA screening (aOR 0.56; 95% CI 0.35-0.91; p = 0.019). Other significant predictors of PSA screening included older age, income > 400% of the federal poverty level, insurance coverage, and healthcare utilization. CONCLUSIONS: Limited English proficiency is associated with significantly lower prevalence of PSA screening among men in the USA. Interventions to mitigate disparities in prostate cancer outcomes should account for limited English proficiency among the barriers to guideline-concordant care.

PURPOSE: To understand racial disparities in germline cancer genetic testing and the role of prior knowledge, attitudes, and sources of information. METHODS: A cross-sectional analysis of the Health Information National Trends Survey 5 (HINTS 5) was conducted between February 24th and June 15th, 2020. The study aimed to investigate knowledge and receipt of genetic testing, attitudes toward the importance of genetic testing in preventing, detecting, and treating cancer, and information sources of genetic testing in the United States of America. RESULTS: Non-Hispanic Black (NHB) and Hispanic race/ethnicity were associated with lower odds of being informed about genetic testing, whereas those of NHB race were more likely to endorse the importance of genetic testing in cancer prevention and treatment. Regarding sources of information about genetic testing: Non-Hispanic Asians were less likely to be informed about genetic testing from television (Mean Predicted Probability (MPP) 0.38 95%CI; 0.21-0.55, (Adjusted Risk Difference) ARD vs. Non-Hispanic White (NHW); -0.228, p = 0.01), NHB were less likely to report being informed about genetic testing from social media (MPP 0.27 95%CI; 0.20-0.34, ARD vs. NHW; -0.139, p < 0.01). CONCLUSIONS: NHB and Hispanic groups face unequal access to information about genetic testing. There are significant race-based differences in information sources. These differences could be used to promote equitable access to cancer genetic testing.

In many psychometric applications, the relationship between the mean of an outcome and a quantitative covariate is too complex to be described by simple parametric functions; instead, flexible nonlinear relationships can be incorporated using penalized splines. Penalized splines can be conveniently represented as a linear mixed effects model (LMM), where the coefficients of the spline basis functions are random effects. The LMM representation of penalized splines makes the extension to multivariate outcomes relatively straightforward. In the LMM, no effect of the quantitative covariate on the outcome corresponds to the null hypothesis that a fixed effect and a variance component are both zero. Under the null, the usual asymptotic chi-square distribution of the likelihood ratio test for the variance component does not hold. Therefore, we propose three permutation tests for the likelihood ratio test statistic: one based on permuting the quantitative covariate, the other two based on permuting residuals. We compare via simulation the Type I error rate and power of the three permutation tests obtained from joint models for multiple outcomes, as well as a commonly used parametric test. The tests are illustrated using data from a stimulant use disorder psychosocial clinical trial.

Background: The COVID-19 pandemic has accelerated telehealth usage. This study aims to understand the impact of sociodemographic factors on telehealth usage during COVID-19 among surgical specialties. Methods: Our data contain surgical outpatient visits at an academic center from five periods between 2019 and 2020. A difference-in-differences regression model was used to examine the effect of exposure variables on virtual visit proportions between prepandemic and postpandemic time periods. Results: Compared with white patients, non-Medicare beneficiaries, and English-proficient patients, the rate of uptake in telehealth visits from prepandemic to postpandemic periods was lower for black patients, Medicare beneficiaries, and non-English-speaking patients, respectively. Surgical subspecialties saw varied usage of telehealth. A strong preference for phone visits by black patients, Medicare beneficiaries, and non-English-speaking patients existed. Conclusion: Phone visits are an important resource for marginalized communities. Understanding disparities in telemedicine usage may inform policy that could alleviate inequities in health care access.

PURPOSE: Smoking is a recognized risk factor for bladder BC and lung cancer LC. We investigated the enduring risk of BC after smoking cessation using U.S. national survey data. Our analysis focused on comparing characteristics of LC and BC patients, emphasizing smoking status and the latency period from smoking cessation to cancer diagnosis in former smokers. MATERIALS AND METHODS: We analyzed data from the National Health and Examination Survey (2003-2016), identifying adults with LC or BC history. Smoking status (never, active, former) and the interval between quitting smoking and cancer diagnosis for former smokers were assessed. We reported descriptive statistics using frequencies and percentages for categorical variables and median with interquartile ranges (IQR) for continuous variables. RESULTS: Among LC patients, 8.9% never smoked, 18.9% active smokers, and 72.2% former smokers. Former smokers had a median interval of 8 years (IQR 2-12) between quitting and LC diagnosis, with 88.3% quitting within 0-19 years before diagnosis. For BC patients, 26.8% never smoked, 22.4% were active smokers, and 50.8% former smokers. Former smokers had a median interval of 21 years (IQR 14-33) between quitting and BC diagnosis, with 49.3% quitting within 0-19 years before diagnosis. CONCLUSIONS: BC patients exhibit a prolonged latency period between smoking cessation and cancer diagnosis compared to LC patients. Despite smoking status evaluation in microhematuria, current risk stratification models for urothelial cancer do not incorporate it. Our findings emphasize the significance of long-term post-smoking cessation surveillance and advocate for integrating smoking history into future risk stratification guidelines.

BACKGROUND: Racial and ethnic disparities in prostate cancer (PCa) mortality are partially mediated by inequities in quality of care. Intermediate- and high-risk PCa can be treated with either surgery or radiation, therefore we designed a study to assess the magnitude of race-based differences in cancer-specific survival between these two treatment modalities. METHODS: Non-Hispanic Black (NHB) and non-Hispanic White (NHW) men with localized intermediate- and high-risk PCa, treated with surgery or radiation between 2004 and 2015 in the Surveillance, Epidemiology and End Results database were included in the study and followed until December 2018. Unadjusted and adjusted survival analyses were employed to compare cancer-specific survival by race and treatment modality. A model with an interaction term between race and treatment was used to assess whether the type of treatment amplified or attenuated the effect of race/ethnicity on prostate cancer-specific mortality (PCSM). RESULTS: 15,178 (20.1%) NHB and 60,225 (79.9%) NHW men were included in the study. NHB men had a higher cumulative incidence of PCSM (p = 0.005) and were significantly more likely to be treated with radiation than NHW men (aOR: 1.89, 95% CI: 1.81-1.97, p < 0.001). In the adjusted models, NHB men were significantly more likely to die from PCa compared with NHW men (aHR: 1.18, 95% CI: 1.03-1.35, p = 0.014), and radiation was associated with a significantly higher odds of PCSM (aHR: 2.10, 95% CI: 1.85-2.38, p < 0.001) compared with surgery. Finally, the interaction between race and treatment on PCSM was not significant, meaning that no race-based differences in PCSM were found within each treatment modality. CONCLUSIONS: NHB men with intermediate- and high-risk PCa had a higher rate of PCSM than NWH men in a large national cancer registry, though NHB and NHW men managed with the same treatment achieved similar PCa survival outcomes. The higher tendency for NHB men to receive radiation was similar in magnitude to the difference in cancer survival between racial and ethnic groups.

There is a great need for statistical methods for analyzing skewed responses in complex sample surveys. Quantile regression is a logical option in addressing this problem but is often accompanied by incorrect variance estimation. We show how the variance can be estimated correctly by including the survey design in the variance estimation process. In a simulation study, we illustrate that the variance of the median regression estimator has a very small relative bias with appropriate coverage probability. The motivation for our work stems from the National Health and Nutrition Examination Survey where we demonstrate the impact of our results on iodine deficiency in females compared with males adjusting for other covariates.

PURPOSE: To describe the national-level patterns of care for local ablative therapy among men with PCa and identify patient- and hospital-level factors associated with the receipt of these techniques. METHODS: We retrospectively interrogated the National Cancer Database (NCDB) for men with clinically localized PCa between 2010 and 2017. The main outcome was receipt of local tumor ablation with either cryo- or laser-ablation, and "other method of local tumor destruction including high-intensity focused ultrasound (HIFU)". Patient level, hospital level, and demographic variables were collected. Mixed effect logistic regression models were fitted to identify separately patient- and hospital-level predictors of receipt of local ablative therapy. RESULTS: Overall, 11,278 patients received ablative therapy, of whom 78.8% had cryotherapy, 15.6% had laser, and 5.7% had another method including HIFU. At the patient level, men with intermediate-risk PCa were more likely to be treated with local ablative therapy (OR 1.05; 95% CI 1.00-1.11; p = 0.05), as were men with Charlson Comorbidity Index > 1 (OR 1.36; 95% CI 1.29-1.43; p < 0.01), men between 71 and 80 years (OR 3.70; 95% CI 3.43-3.99; p < 0.01), men with Medicare insurance (OR 1.38; 95% 1.31-1.46; p < 0.01), and an income < $47,999 (OR 1.16; 95% CI 1.06-1.21; p < 0.01). At the hospital-level, local ablative therapy was less likely to be performed in academic/research facilities (OR 0.45; 95% CI 0.32-0.64; p < 0.01). CONCLUSIONS: Local ablative therapy for PCa treatment is more commonly offered among older and comorbid patients. Future studies should investigate the uptake of these technologies in non-hospital-based settings and in light of recent changes in insurance coverage.

INTRODUCTION: Colorectal cancer screening continuously decreased its mortality and incidence. In 2010, the Affordable Care Act extended Medicaid eligibility to low-income and childless adults. Some states elected to adopt Medicaid at different times while others chose not to. Past studies on the effects of Medicaid expansion on colorectal cancer screening showed equivocal results based on short-term data following expansion. AIMS: To examine the long-term impact of Medicaid expansion on colorectal cancer screening among its targeted population at its decade mark. METHODS: Behavioral Risk Factor Surveillance System data were extracted for childless adults below 138% federal poverty level in states with different Medicaid expansion statuses from 2012 to 2020. States were stratified into very early expansion states, early expansion states, late expansion states, and non-expansion states. Colorectal cancer screening prevalence was determined for eligible respondents. Difference-in-differences analyses were used to examine the effect of Medicaid expansion on colorectal cancer screening in states with different expansion statuses. RESULTS: Colorectal cancer screening prevalence in very early, early, late, and non-expansion states all increased during the study period (40.45% vs. 48.14%, 47.52% vs 61.06%, 46.06% vs 58.92%, and 43.44% vs 56.70%). Difference-in-differences analysis showed significantly increased CRC screening prevalence in very early expansion states during 2016 compared to non-expansion states (Crude difference-in-differences + 16.45%, p = 0.02, Adjusted difference-in-differences + 15.9%, p = 0.03). No statistical significance was observed among other years and groups. CONCLUSIONS: Colorectal cancer screening increased between 2012 and 2020 in all states regardless of expansion status. However, Medicaid expansion is not associated with long-term increased colorectal cancer screening prevalence.

BACKGROUND/AIMS: High follow-up is critical in randomized clinical trials. We developed novel approaches to modify in-person visits and complete follow-up during COVID-19. Since these strategies are broadly applicable to circumstances wherein follow-up is difficult, they may help in contingency planning. The objective of this article is to develop and evaluate new approaches to replace detailed, in-person study visits for two trials focused on preventing diabetic foot complications. METHODS: A quasi-experimental pre-post design compared approaches for follow-up during COVID-19 to approaches pre-COVID-19. Study subjects were outpatients at two Veterans Affairs Medical Centers. Following a research "hold," research resumed in February 2021 for Self-monitoring, Thermometry and Educating Patients for Ulcer Prevention (STEP UP) (n = 241), which focused on preventing recurrent foot ulcers, and in April 2021 for Preventing Amputation by Tailored Risk-based Intervention to Optimize Therapy (PATRIOT) (n = 406), which focused on preventing pre-ulcerative and ulcerative lesions. To complete data collection, we shortened visits, focused on primary and secondary outcomes, and conducted virtual visits when appropriate. For STEP UP, we created a 20-min assessment process that could be administered by phone. Since PATRIOT required plantar photographs to assess foot lesions, we conducted short face-to-face visits. We explored differences and assessed proportion completing visit, visit completion/100 person-months and compared COVID-19 to pre- COVID-19 using unadjusted risk ratios, incidence rate ratios, all with associated 95% confidence intervals (CIs). Finally, we report time-to-visit curves. RESULTS: In both studies, participants whose follow-up concluded pre- COVID-19 seemed older than those whose follow-up concluded during COVID-19 (PATRIOT: 68.0 (67.2, 68.9) versus 65.2 years (61.9, 68.5); STEP UP: 67.5 (66.2, 68.9) versus 65.3 (63.3, 67.3)). For STEP UP, we completed 91 visits pre- COVID-19 (37.8% (31.6%, 44.2%)) and 63 visits during COVID-19 (78.8% (68.2%, 87.1%)). This was over 1309 person-months pre-COVID-19, and over 208.8 person-months during COVID-19; the visit completion rate/100 person-months were: pre-COVID-19 7.0 (5.6, 8.5), COVID-19 30.2 (23.2, 38.6); risk ratio: 2.1 (1.7, 2.5); and incidence rate ratio 4.3 (3.1, 5.9). Similarly, for PATRIOT, we completed 316 visits pre-COVID-19 (77.8% (73.5%, 81.8%)) and 27 assessments during COVID-19 (84.4% (67.2%, 94.7%)). This was over 1192.7 person-months pre-COVID-19 and 39.3 person-months during COVID-19. The visit completion rate/100 person-months in PATRIOT were: pre-COVID-19 2.7 (2.4, 3.0), COVID-19 6.9 (4.5, 10); risk ratio 1.1 (0.9, 1.3); incidence rate ratio 2.6 (1.8, 3.8). For both studies, the follow-up curves began separating at < 2 months. CONCLUSIONS: We achieved higher completion rates during COVID-19 compared to pre-COVID-19 by modifying visits and focusing on primary and secondary outcomes. These strategies prevent excessive missing data, support more valid conclusions, and improve efficiency. They may provide important alternative strategies to achieving higher follow-up in randomized clinical trials.

INTRODUCTION: Robot-assisted laparoscopic prostatectomy (RALP) and transurethral resection of bladder tumor (TURBT) are two common surgeries for prostate and bladder cancer. We aim to assess the trends in the site of care for RALP and TURBT before and after the COVID outbreak. MATERIALS AND METHODS: We identified adults who underwent RALP and TURBT within the California Healthcare Cost and Utilization Project State Inpatient Database and the State Ambulatory Surgery Database between 2018 and 2020. Multivariable analysis and spline analysis with a knot at COVID outbreak were performed to investigate the time trend and factors associated with ambulatory RALP and TURBT. RESULTS: Among 17,386 RALPs, 6,774 (39.0%) were ambulatory. Among 25,070 TURBTs, 21,573 (86.0%) were ambulatory. Pre-COVID, 33.5% of RALP and 85.3% and TURBT were ambulatory, which increased to 53.8% and 88.0% post-COVID (both p < 0.001). In multivariable model, RALP and TURBT performed after outbreak in March 2020 were more likely ambulatory (OR 2.31, p < 0.0001; OR 1.25, p < 0.0001). There was an overall increasing trend in use of ambulatory RALP both pre- and post-COVID, with no significant change of trend at the time of outbreak (p = 0.642). TURBT exhibited an increased shift towards ambulatory sites post-COVID (p < 0.0001). CONCLUSIONS: We found a shift towards ambulatory RALP and TURBT following COVID outbreak. There was a large increase in ambulatory RALP post-COVID, but the trend of change was not significantly different pre- and post-COVID - possibly due to a pre-existing trend towards ambulatory RALP which predated the pandemic.

INTRODUCTION: Accurate estimation of an expected discharge date (EDD) early during hospitalization impacts clinical operations and discharge planning. METHODS: We conducted a retrospective study of patients discharged from six general medicine units at an academic medical center in Boston, MA from January 2017 to June 2018. We retrieved all EDD entries and patient, encounter, unit, and provider data from the electronic health record (EHR), and public weather data. We excluded patients who expired, discharged against medical advice, or lacked an EDD within the first 24 h of hospitalization. We used generalized estimating equations in a multivariable logistic regression analysis to model early EDD accuracy (an accurate EDD entered within 24 h of admission), adjusting for all covariates and clustering by patient. We similarly constructed a secondary multivariable model using covariates present upon admission alone. RESULTS: Of 3917 eligible hospitalizations, 890 (22.7%) had at least one accurate early EDD entry. Factors significantly positively associated (OR > 1) with an accurate early EDD included clinician-entered EDD, admit day and discharge day during the work week, and teaching clinical units. Factors significantly negatively associated (OR < 1) with an accurate early EDD included Elixhauser Comorbidity Index ≥ 11 and length of stay of two or more days. C-statistics for the primary and secondary multivariable models were 0.75 and 0.60, respectively. CONCLUSIONS: EDDs entered within the first 24 h of admission were often inaccurate. While several variables from the EHR were associated with accurate early EDD entries, few would be useful for prospective prediction.

PURPOSE: Our goal was to assess patterns of adoption and population-level outcomes of prostate magnetic resonance imaging (MRI) and association with surgical outcomes across a sample of U.S. elderly. MATERIALS AND METHODS: This population-based retrospective study used Surveillance Epidemiology, and End Results-Medicare linked data from 2003-2016 to identify men receiving prostatectomy for prostate cancer. We characterized the proportion of men receiving preoperative MRI in each year and in each hospital referral region (HRR). A 2-stage instrumental variable analysis was performed to assess the association of preoperative MRI with margin status, surgical complications and further cancer-directed therapies. RESULTS: A total of 19,369 men received prostatectomy in 72 HRRs; the mean age was 70.2 years (SD 3.2). The proportion of men receiving a preoperative MRI increased from 2.9% to 28.2% over the study period and ranged from 0.0% to 28.8% in the different HRRs. In our instrumental variable analysis, preoperative MRI was associated with lower odds of positive surgical margin (OR 0.84, 95% CI 0.72-0.97, p=0.01) lower odds of blood transfusions at 30 and 90 days (OR 0.56, 95% CI 0.38-0.83, p=0.003 and OR 0.58, 95% CI 0.41-0.84, p=0.004) but higher odds of further treatments (OR 1.49, 95% CI 1.32-1.70, p <0.001). CONCLUSIONS: Given that a minority of men receive presurgical MRIs with marked geographic variability, the association of MRI with lower odds of positive surgical margin suggests that efforts to support the dissemination of prostate MRI may improve surgical outcomes-but may come with a tendency for more resource-intensive cancer care overall.

BACKGROUND: The first surge of the COVID-19 pandemic entirely altered healthcare delivery. Whether this also altered the receipt of high- and low-value care is unknown. OBJECTIVE: To test the association between the April through June 2020 surge of COVID-19 and various high- and low-value care measures to determine how the delivery of care changed. DESIGN: Difference in differences analysis, examining the difference in quality measures between the April through June 2020 surge quarter and the January through March 2020 quarter with the same 2 quarters' difference the year prior. PARTICIPANTS: Adults in the MarketScan® Commercial Database and Medicare Supplemental Database. MAIN MEASURES: Fifteen low-value and 16 high-value quality measures aggregated into 8 clinical quality composites (4 of these low-value). KEY RESULTS: We analyzed 9,352,569 adults. Mean age was 44 years (SD, 15.03), 52% were female, and 75% were employed. Receipt of nearly every type of low-value care decreased during the surge. For example, low-value cancer screening decreased 0.86% (95% CI, -1.03 to -0.69). Use of opioid medications for back and neck pain (DiD +0.94 [95% CI, +0.82 to +1.07]) and use of opioid medications for headache (DiD +0.38 [95% CI, 0.07 to 0.69]) were the only two measures to increase. Nearly all high-value care measures also decreased. For example, high-value diabetes care decreased 9.75% (95% CI, -10.79 to -8.71). CONCLUSIONS: The first COVID-19 surge was associated with receipt of less low-value care and substantially less high-value care for most measures, with the notable exception of increases in low-value opioid use.

PURPOSE: To assess whether the 5-item Frailty Index (5i-FI) predicts surgical complications of endoscopic surgery for benign prostatic obstruction (BPO) and examine the rates of these complications across BPO surgical modalities adjusting for patient frailty. METHODS: The ACS-NSQIP registry was queried for patients who underwent transurethral resection of the prostate (TURP), photoselective vaporization of the prostate (PVP), and laser enucleation of the prostate (LEP) between 2009 and 2019. Patients' frailties were estimated using the 5i-FI. We assessed the association between 5i-FI and the following endpoints: all complications, major complications (Clavien-Dindo ≥ 3), length of stay (LOS) ≥ 2 days, and 30-day postoperative readmission. Inverse probability of treatment weighting (IPTW) was used to account for selection bias in treatment allocation. IPTW-adjusted rates for 30-day complications were compared between surgical modalities. RESULTS: The cohort included 38,399 (62.6%) TURP, 19,121 (31.2%) PVP, and 3797 (6.2%) LEP. Men with 5i-FI score ≥ 2 were more likely to receive TURP (22.7%) and PVP (22.5%) than LEP (18.8%). 5i-FI ≥ 2 was associated with higher odds of all complications (OR 1.50), major complications (OR 1.63), LOS ≥ 2 (OR 1.31), and readmission (OR 1.65). After IPTW, LEP had the lowest rates for all complications (6.29%; 95%CI 5.48-7.20), major complications (2.30%; 95%CI 1.83-2.89), and readmission (3.80%; 95%CI 3.18-4.53). CONCLUSION: The 5i-FI score is an independent predictor of 30-day postoperative surgical complications after endoscopic BPO surgery. After IPTW, LEP and PVP were associated with lower rates of complications than TURP. However, frail patients were less likely to undergo PVP and LEP.

BACKGROUND: The low-risk cesarean delivery (CD) rate is an established performance indicator for providers in maternity care for quality improvement purposes. PURPOSE: Our objectives were to assess nurse performance using adjusted nurse-level CD rates and to compare methods of identifying nurse outliers. METHODS: We conducted a retrospective, cohort study of 6970 births attended by 181 registered nurses in one hospital's maternity unit. Adjusted and unadjusted nurse-level CD rates were compared and agreement between 3 definitions (statistical, top decile, over a benchmark) of outliers calculated. RESULTS: Adjusted nurse-level CD rates varied from 5.5% to 53.2%, and the unadjusted rates varied from 5% to 50%. Risk adjustment had little impact on the ranking of nurses, and outliers were consistently identified by 3 definitions. CONCLUSIONS: Trade-offs between statistical certainty and feasibility need to be considered when classifying nurse outliers. Findings can help target interventions to improve nurse performance.

Genitourinary surgeons and oncologists are particularly interested in whether a robotic surgery improves times to Prostate Specific Antigen (PSA) recurrence compared to a non-robotic surgery for removing the cancerous prostate. Time to PSA recurrence is an example of a survival time that is typically interval-censored between two consecutive clinical inspections with opposite test results. In addition, success of medical devices and technologies often depends on factors such as experience and skill level of the medical service providers, thus leading to clustering of these survival times. For analyzing the effects of surgery types and other covariates on median of clustered interval-censored time to post-surgery PSA recurrence, we present three competing novel models and associated frequentist and Bayesian analyses. The first model is based on a transform-both-sides of survival time with Gaussian random effects to account for the within-cluster association. Our second model assumes an approximate marginal Laplace distribution for the transformed log-survival times with a Gaussian copula to accommodate clustering. Our third model is a special case of the second model with Laplace distribution for the marginal log-survival times and Gaussian copula for the within-cluster association. Simulation studies establish the second model to be highly robust against extreme observations while estimating median regression coefficients. We provide a comprehensive comparison among these three competing models based on the model properties and the computational ease of their Frequentist and Bayesian analysis. We also illustrate the practical implementations and uses of these methods via analysis of a simulated clustered interval-censored data-set similar in design to a post-surgery PSA recurrence study.

BACKGROUND: Massachusetts is a northeastern state with universally mandated health insurance since 2006. Although Black men have generally worse prostate cancer outcomes, emerging data suggest that they may experience equivalent outcomes within a fully insured system. In this setting, the authors analyzed treatments and outcomes of non-Hispanic White and Black men in Massachusetts. METHODS: White and Black men who were 20 years old or older and had been diagnosed with localized intermediate- or high-risk nonmetastatic prostate cancer in 2004-2015 were identified in the Massachusetts Cancer Registry. Adjusted logistic regression models were used to assess predictors of definitive therapy. Adjusted and unadjusted survival models compared cancer-specific mortality. Interaction terms were then used to assess whether the effect of race varied between counties. RESULTS: A total of 20,856 men were identified. Of these, 19,287 (92.5%) were White. There were significant county-level differences in the odds of receiving definitive therapy and survival. Survival was worse for those with high-risk cancer (adjusted hazard ratio [HR], 1.50; 95% CI, 1.4-1.60) and those with public insurance (adjusted HR for Medicaid, 1.69; 95% CI, 1.38-2.07; adjusted HR for Medicare, 1.2; 95% CI, 1.14-1.35). Black men were less likely to receive definitive therapy (adjusted odds ratio, 0.78; 95% CI, 0.74-0.83) but had a 17% lower cancer-specific mortality (adjusted HR, 0.83; 95% CI, 0.7-0.99). CONCLUSIONS: Despite lower odds of definitive treatment, Black men experience decreased cancer-specific mortality in comparison with White men in Massachusetts. These data support the growing body of research showing that Black men may achieve outcomes equivalent to or even better than those of White men within the context of a well-insured population. LAY SUMMARY: There is a growing body of evidence showing that the excess risk of death among Black men with prostate cancer may be caused by disparities in access to care, with few or no disparities seen in universally insured health systems such as the Veterans Affairs and US Military Health System. Therefore, the authors sought to assess racial disparities in prostate cancer in Massachusetts, which was the earliest US state to mandate universal insurance coverage (in 2006). Despite lower odds of definitive treatment, Black men with prostate cancer experience reduced cancer-specific mortality in comparison with White men in Massachusetts. These data support the growing body of research showing that Black men may achieve outcomes equivalent to or even better than those of White men within the context of a well-insured population.

OBJECTIVE: The aim of this study was to estimate the effect of index surgical care setting on perioperative costs and readmission rates across 4 common elective general surgery procedures. SUMMARY BACKGROUND DATA: Facility fees seem to be a driving force behind rising US healthcare costs, and inpatient-based fees are significantly higher than those associated with ambulatory services. Little is known about factors influencing where patients undergo elective surgery. METHODS: All-payer claims data from the 2014 New York and Florida Healthcare Cost and Utilization Project were used to identify 73,724 individuals undergoing an index hernia repair, primary total or partial thyroidectomy, laparoscopic cholecystectomy, or laparoscopic appendectomy in either the inpatient or ambulatory care setting. Inverse probability of treatment weighting-adjusted gamma generalized linear and logistic regression was employed to compare costs and 30-day readmission between inpatient and ambulatory-based surgery, respectively. RESULTS: Approximately 87% of index surgical cases were performed in the ambulatory setting. Adjusted mean index surgical costs were significantly lower among ambulatory versus inpatient cases for all 4 procedures (P < 0.001 for all). Adjusted odds of experiencing a 30-day readmission after thyroidectomy [odds ratio (OR) 0.70, 95% confidence interval (CI), 0.53-0.93; P = 0.03], hernia repair (OR 0.28, 95% CI, 0.20-0.40; P < 0.001), and laparoscopic cholecystectomy (OR 0.37, 95% CI, 0.32-0.43; P < 0.001) were lower in the ambulatory versus inpatient setting. Readmission rates among ambulatory versus inpatient-based laparoscopic appendectomy were comparable (OR 0.63, 95% CI, 0.31-1.26; P = 0.19). CONCLUSIONS: Ambulatory surgery offers significant costs savings and generally superior 30-day outcomes relative to inpatient-based care for appropriately selected patients across 4 common elective general surgery procedures.
