RESUMEN
PURPOSE: Screening history influences stage at detection, but regular preventive care may also influence breast tumor diagnostic characteristics. Few studies have evaluated healthcare utilization (both screening and primary care) in racially diverse screening-eligible populations. METHODS: This analysis included 2,058 women age 45-74 (49% Black) from the Carolina Breast Cancer Study, a population-based cohort of women diagnosed with invasive breast cancer between 2008 and 2013. Screening history (threshold 0.5 mammograms per year) and pre-diagnostic healthcare utilization (i.e. regular care, based on responses to "During the past ten years, who did you usually see when you were sick or needed advice about your health?") were assessed as binary exposures. The relationship between healthcare utilization and tumor characteristics were evaluated overall and race-stratified. RESULTS: Among those lacking screening, Black participants had larger tumors (5 + cm) (frequency 19.6% vs 11.5%, relative frequency difference (RFD) = 8.1%, 95% CI 2.8-13.5), but race differences were attenuated among screening-adherent participants (10.2% vs 7.0%, RFD = 3.2%, 0.2-6.2). Similar trends were observed for tumor stage and mode of detection (mammogram vs lump). Among all participants, those lacking both screening and regular care had larger tumors (21% vs 8%, RR = 2.51, 1.76-3.56) and advanced (3B +) stage (19% vs 6%, RR = 3.15, 2.15-4.63) compared to the referent category (screening-adherent and regular care). Under-use of regular care and screening was more prevalent in socioeconomically disadvantaged areas of North Carolina. CONCLUSIONS: Access to regular care is an important safeguard for earlier detection. Our data suggest that health equity interventions should prioritize both primary care and screening.

Immortal time bias is a well-recognized bias in clinical epidemiology but is rarely discussed in environmental epidemiology. Under the target trial framework, this bias is formally conceptualized as a misalignment between the start of study follow-up (time 0) and treatment assignment. This misalignment can occur when attained duration of follow-up is encoded into treatment assignment using minimums, maximums, or averages. The bias can be exacerbated in the presence of time trends commonly found in environmental exposures. Using lung cancer cases from the California Cancer Registry (2000-2010) linked with estimated concentrations of particulate matter less than or equal to 2.5 µm in aerodynamic diameter (PM2.5), we replicated previous studies that averaged PM2.5 exposure over follow-up in a time-to-event model. We compared this approach with one that ensures alignment between time 0 and treatment assignment, a discrete-time approach. In the former approach, the estimated overall hazard ratio for a 5-µg/m3 increase in PM2.5 was 1.38 (95% confidence interval: 1.36, 1.40). Under the discrete-time approach, the estimated pooled odds ratio was 0.99 (95% confidence interval: 0.98, 1.00). We conclude that the strong estimated effect in the former approach was likely driven by immortal time bias, due to misalignment at time 0. Our findings highlight the importance of appropriately conceptualizing a time-varying environmental exposure under the target trial framework to avoid introducing preventable systematic errors.

BACKGROUND: To test whether nomograms developed by NRG Oncology for oropharyngeal squamous cell carcinoma (OPSCC) patients could be validated in an independent population-based sample. METHODS: The authors tested nomograms for estimating progression-free survival (PFS) and overall survival (OS) in patients from the Veterans Health Administration with previously untreated locoregionally advanced OPSCC, diagnosed between 2008 and 2017, managed with definitive radiotherapy with or without adjuvant systemic therapy. Covariates were age, performance status, p16 status, T/N category, smoking history, education history, weight loss, marital status, and anemia. We used multiple imputation to handle missing data and performed sensitivity analyses on complete cases. Validation was assessed via Cox proportional hazards models, log-rank tests, and c-indexes. RESULTS: A total of 4007 patients met inclusion criteria (658 patients had complete data). Median follow-up time was 3.20 years, with 967 progression events and 471 noncancer deaths. Each risk score was associated with poorer outcomes per unit increase (PFS score, hazard ratio [HR], 1.42 [1.37-1.47]; OS score, HR, 1.40 [1.34-1.45]). By risk score quartile, 2-year PFS estimates were 89.2%, 78.5%, 65.8%, and 48.3%; OS estimates were 92.6%, 83.6%, 73.9%, and 51.3%, respectively (P < .01 for all comparisons). C-indices for models of PFS and OS were 0.65 and 0.67, for all patients, respectively (0.69 and 0.73 for complete cases). The nomograms slightly overestimated PFS and OS in the overall cohort but exhibited high agreement in complete cases. CONCLUSIONS: NRG nomograms were effective for predicting PFS and OS for patients with OPSCC, supporting their broader applicability in the OPSCC population undergoing definitive radiotherapy.

BACKGROUND: Racial disparities in functional outcomes after total knee arthroplasty (TKA) exist. Whether differences in rehabilitation utilization contribute to these disparities remains to be investigated. METHODS: Among 8349 women enrolled in the prospective Women's Health Initiative cohort who underwent primary TKA between 2006 and 2013, rehabilitation utilization was determined through linked Medicare claims data. Postacute discharge destination (home, skilled nursing facility, and inpatient rehabilitation facility), facility length of stay, and number of home health physical therapy (HHPT) and outpatient physical therapy (OPPT) sessions were compared between racial groups. RESULTS: Non-Hispanic black women had worse physical function (median score, 65 vs 70) and higher likelihood of disability (13.2% vs 6.9%) than non-Hispanic white women before surgery. After TKA, black women were more likely to be discharged postacutely to an institutional facility (64.3% vs 54.5%) than white women, were more likely to receive HHPT services (52.6% vs 47.8%), and received more HHPT and OPPT sessions. After stratification by postacute discharge setting, the likelihood of receipt of HHPT or OPPT services was similar between racial groups. No significant difference in receipt of HHPT or OPPT services was found after use of propensity score weighting to balance health and medical characteristics indicating severity of need for physical therapy services. CONCLUSION: Rehabilitation utilization was generally comparable between black and white women who received TKA when accounting for need. There was no evidence of underutilization of post-TKA rehabilitation services, and thus disparities in post-TKA functional outcomes do not appear to be a result of inequitable receipt of rehabilitation care.

Objective- Arterial calcification is highly correlated with underlying atherosclerosis. Arterial calcification of the thoracic aorta is evident in many older individuals at high susceptibility to aging-related diseases and non-cardiovascular disease (CVD)-related mortality. In this study, we evaluated the association of thoracic aorta calcification (TAC) with non-CVD morbidity and mortality. Approach and Results- We analyzed data from participants in the Multi-Ethnic Study of Atherosclerosis, a prospective cohort study of subclinical atherosclerosis, in which participants underwent cardiac computed tomography at baseline and were followed longitudinally for incident CVD events and non-CVD events. Using modified proportional hazards models accounting for the competing risk of CVD death and controlling for demographics, CVD risk factors, coronary artery calcium, and CVD events, we evaluated whether TAC was independently associated with non-CVD morbidity and mortality. Among 6765 participants (mean age, 62 years), 704 non-CVD deaths occurred for a median follow-up of 12.2 years. Compared with no TAC, the highest tertile of TAC volume was associated with a higher risk of non-CVD mortality (hazard ratio, 1.56; 95% confidence interval, 1.23-1.97), as well as several non-CVD diagnoses, including hip fracture (2.14; 1.03-4.46), chronic obstructive pulmonary disease (2.06; 1.29-3.29), and pneumonia (1.79; 1.30-2.45), with magnitudes of association that were larger than for those of coronary artery calcium. Conclusions- TAC is associated with non-CVD morbidity and non-CVD mortality, potentially through a pathway that is unrelated to atherosclerosis. TAC may be a general marker of biological aging and an indicator of increased risk of non-CVD and death.

The incomparability of old and new classification systems for describing the same data can be seen as a missing-data problem, and, under certain assumptions, multiple imputation may be used to "bridge" 2 classification systems. One example of such a change is the introduction of detailed Asian-American race/ethnicity classifications on the 2003 version of the US national death certificate, which was adopted for use by 38 states between 2003 and 2011. Using county- and decedent-level data from 3 different national sources for pre- and postadoption years, we fitted within-state multiple-imputation models to impute ethnicities for decedents classified as "other Asian" during preadoption years. We present mortality rates derived using 3 different methods of calculation: 1) including all states but ignoring the gradual adoption of the new death certificate over time, 2) including only the 7 states with complete reporting of all ethnicities, and 3) including all states and applying multiple imputation. Estimates from our imputation model were consistently in the middle of the other 2 estimates, and trend results demonstrated that the year-by-year estimates of the imputation model were more similar to those of the 7-state model. This work demonstrates how multiple imputation can provide a "forward bridging" approach to make more accurate estimates over time in newly categorized populations.

BACKGROUND: A "Table Fallacy," as coined by Westreich and Greenland, reports multiple adjusted effect estimates from a single model. This practice, which remains common in published literature, can be problematic when different types of effect estimates are presented together in a single table. The purpose of this paper is to quantitatively illustrate this potential for misinterpretation with an example estimating the effects of preeclampsia on preterm birth. METHODS: We analysed a retrospective population-based cohort of 2 963 888 singleton births in California between 2007 and 2012. We performed a modified Poisson regression to calculate the total effect of preeclampsia on the risk of PTB, adjusting for previous preterm birth. pregnancy alcohol abuse, maternal education, and maternal socio-demographic factors (Model 1). In subsequent models, we report the total effects of previous preterm birth, alcohol abuse, and education on the risk of PTB, comparing and contrasting the controlled direct effects, total effects, and confounded effect estimates, resulting from Model 1. RESULTS: The effect estimate for previous preterm birth (a controlled direct effect in Model 1) increased 10% when estimated as a total effect. The risk ratio for alcohol abuse, biased due to an uncontrolled confounder in Model 1, was reduced by 23% when adjusted for drug abuse. The risk ratio for maternal education, solely a predictor of the outcome, was essentially unchanged. CONCLUSIONS: Reporting multiple effect estimates from a single model may lead to misinterpretation and lack of reproducibility. This example highlights the need for careful consideration of the types of effects estimated in statistical models.

BACKGROUND: Point-of-care ultrasound (POCUS) can potentially help distinguish cellulitis from abscess, which can appear very similar on physical examination but necessitate different treatment approaches. OBJECTIVE: To compare POCUS guidance vs. clinical assessment alone on the management of pediatric skin and soft tissue infections (SSTI) in the emergency department (ED) setting. METHODS: Children ages 6 months to 18 years presenting to participating EDs with SSTIs ≥ 1 cm were eligible. All treatment decisions, including use of POCUS, were at the discretion of the treating clinicians. Patients were divided into those managed with POCUS guidance (POCUS group) and those managed using clinical assessment alone (non-POCUS group). Primary outcome was clinical treatment failure at 7-10 days (unscheduled ED return visit or admission, procedural intervention, change in antibiotics therapy). Secondary outcomes were ED length of stay, discharge rate, use of alternative imaging, and need for procedural sedation. POCUS utility and impact on management decisions were also assessed by treating clinicians. RESULTS: In total, 321 subjects (327 lesions) were analyzed, of which 299 (93%) had completed follow-up. There was no significant difference between the POCUS and non-POCUS groups in any of the primary or secondary outcomes. Management plan was changed in the POCUS group in 22.9% of cases (13.8% from medical to surgical, 9.1% from surgical to medical). Clinicians reported increased benefit of POCUS in cases of higher clinical uncertainty. CONCLUSIONS: Use of POCUS was not associated with decreased ED treatment failure rate or process outcomes in pediatric SSTI patients. However, POCUS changed the management plan in approximately one in four cases.

OBJECTIVE: To compare the complications and charges of robotic vs. laparoscopic vs. open surgeries in morbidly obese patients treated for endometrial cancer. METHODS: Data were obtained from the Nationwide Inpatient Sample from 2011. Chi-squared, Wilcoxon rank sum two-sample tests, and multivariate analyses were used for statistical analyses. RESULTS: Of 1087 morbidly obese (BMI ≥40kg/m(2)) endometrial cancer patients (median age: 59years, range: 22 to 89), 567 (52%) had open surgery (OS), 98 (9%) laparoscopic (LS), and 422 (39%) robotic surgery (RS). 23% of OS, 13% of LS, and 8% of RS patients experienced an intraoperative or postoperative complication including: blood transfusions, mechanical ventilation, urinary tract injury, gastrointestinal injury, wound debridement, infection, venous thromboembolism, and lymphedema (p<0.0001). RS and LS patients were less likely to receive blood transfusions compared to OS (5% and 6% vs. 14%, respectively; p<0.0001). The median lengths of hospitalization for OS, LS, and RS patients were 4, 1, and 1days, respectively (p<0.0001). Median total charges associated with OS, LS, and RS were $39,281, $40,997, and $45,030 (p=0.037), respectively. CONCLUSIONS: In morbidly obese endometrial cancer patients, minimally invasive robotic or laparoscopic surgeries were associated with fewer complications and less days of hospitalization relative to open surgery. Compared to laparoscopic approach, robotic surgeries had comparable rates of complications but higher charges.

OBJECTIVE: To evaluate the hospital and patient factors associated with robotic surgery for endometrial cancer in the United States. METHODS: Data was obtained from the Nationwide Inpatient Sample from the year 2010. Chi-squared and multivariate analyses were used for statistical analysis. RESULTS: Of the 6560 endometrial cancer patients who underwent surgery, the median age was 62 (range: 22 to 99). 1647 (25%) underwent robotic surgery, 820 (13%) laparoscopic, and 4093 (62%) had open surgery. The majority was White (65%). Hospitals with 76 or more hysterectomy cases for endometrial cancer patients per year (4% of hospitals in the study) performed 31% of all hysterectomies and 40% of all robotic hysterectomies (p<0.01). 29% of Whites had robotic surgery compared to 15% of Hispanics, 12% of Blacks, and 11% of Asians (p<0.01). Patients with upper-middle and high incomes underwent robotic surgery more than patients with low or middle incomes (p<0.01). 27% of Medicare patients and 26% of patients with private insurance had robotic surgery compared to only 14% of Medicaid patients and 12% of uninsured patients (p<0.01). CONCLUSIONS: The majority of robotic surgeries for endometrial cancer were performed at a small number of high-volume hospitals in the United States. Socioeconomic status, insurance type, and race were also important predictors for the use of RS. Further studies are warranted to better understand the barriers to receiving minimally invasive surgery.

OBJECTIVE: This study aimed to investigate the associations of quality management systems with teamwork and safety climate, and to describe and compare differences in perceptions of teamwork climate and safety climate among clinical leaders and frontline clinicians. METHOD: We used a multi-method, cross-sectional approach to collect survey data of quality management systems and perceived teamwork and safety climate. Our data analyses included descriptive and multilevel regression methods. SETTING AND PARTICIPANTS: Data on implementation of quality management system from seven European countries were evaluated including patient safety culture surveys from 3622 clinical leaders and 4903 frontline clinicians. MAIN OUTCOME MEASURES: Perceived teamwork and safety climate. RESULTS: Teamwork climate was reported as positive by 67% of clinical leaders and 43% of frontline clinicians. Safety climate was perceived as positive by 54% of clinical leaders and 32% of frontline clinicians. We found positive associations between implementation of quality management systems and teamwork and safety climate. CONCLUSIONS: Our findings, which should be placed in a broader clinical quality improvement context, point to the importance of quality management systems as a supportive structural feature for promoting teamwork and safety climate. To gain a deeper understanding of this association, further qualitative and quantitative studies using longitudinally collected data are recommended. The study also confirms that more clinical leaders than frontline clinicians have a positive perception of teamwork and safety climate. Such differences should be accounted for in daily clinical practice and when tailoring initiatives to improve teamwork and safety climate.

OBJECTIVE: To define a checklist that can be used to assess the performance of a department and evaluate the implementation of quality management (QM) activities across departments or pathways in acute care hospitals. DESIGN: We developed and tested a checklist for the assessment of QM activities at department level in a cross-sectional study using on-site visits by trained external auditors. SETTING AND PARTICIPANTS: A sample of 292 hospital departments of 74 acute care hospitals across seven European countries. In every hospital, four departments for the conditions: acute myocardial infarction (AMI), stroke, hip fracture and deliveries participated. MAIN OUTCOME MEASURES: Four measures of QM activities were evaluated at care pathway level focusing on specialized expertise and responsibility (SER), evidence-based organization of pathways (EBOP), patient safety strategies and clinical review (CR). RESULTS: Participating departments attained mean values on the various scales between 1.2 and 3.7. The theoretical range was 0-4. Three of the four QM measures are identical for the four conditions, whereas one scale (EBOP) has condition-specific items. Correlations showed that every factor was related, but also distinct, and added to the overall picture of QM at pathway level. CONCLUSION: The newly developed checklist can be used across various types of departments and pathways in acute care hospitals like AMI, deliveries, stroke and hip fracture. The anticipated users of the checklist are internal (e.g. peers within the hospital and hospital executive board) and external auditors (e.g. healthcare inspectorate, professional or patient organizations).

OBJECTIVE: The assessment of integral quality management (QM) in a hospital requires measurement and monitoring from different perspectives and at various levels of care delivery. Within the DUQuE project (Deepening our Understanding of Quality improvement in Europe), seven measures for QM were developed. This study investigates the relationships between the various quality measures. DESIGN: It is a multi-level, cross-sectional, mixed-method study. SETTING AND PARTICIPANTS: As part of the DUQuE project, we invited a random sample of 74 hospitals in 7 countries. The quality managers of these hospitals were the main respondents. Furthermore, data of site visits of external surveyors assessing the participating hospitals were used. MAIN OUTCOME MEASURES: Three measures of QM at hospitals level focusing on integral systems (QMSI), compliance with the Plan-Do-Study-Act quality improvement cycle (QMCI) and implementation of clinical quality (CQII). Four measures of QM activities at care pathway level focusing on Specialized expertise and responsibility (SER), Evidence-based organization of pathways (EBOP), Patient safety strategies (PSS) and Clinical review (CR). RESULTS: Positive significant associations were found between the three hospitals level QM measures. Results of the relationships between levels were mixed and showed most associations between QMCI and department-level QM measures for all four types of departments. QMSI was associated with PSS in all types of departments. CONCLUSION: By using the seven measures of QM, it is possible to get a more comprehensive picture of the maturity of QM in hospitals, with regard to the different levels and across various types of hospital departments.

OBJECTIVE: The objective of this study was to describe the involvement of patients or their representatives in quality management (QM) functions and to assess associations between levels of involvement and the implementation of patient-centred care strategies. DESIGN: A cross-sectional, multilevel STUDY DESIGN: that surveyed quality managers and department heads and data from an organizational audit. SETTING: Randomly selected hospitals (n = 74) from seven European countries (The Czech Republic, France, Germany, Poland, Portugal, Spain and Turkey). PARTICIPANTS: Hospital quality managers (n = 74) and heads of clinical departments (n = 262) in charge of four patient pathways (acute myocardial infarction, stroke, hip fracture and deliveries) participated in the data collection between May 2011 and February 2012. MAIN OUTCOME MEASURES: Four items reflecting essential patient-centred care strategies based on an on-site hospital visit: (1) formal survey seeking views of patients and carers, (2) written policies on patients' rights, (3) patient information literature including guidelines and (4) fact sheets for post-discharge care. The main predictors were patient involvement in QM at the (i) hospital level and (ii) pathway level. RESULTS: Current levels of involving patients and their representatives in QM functions in European hospitals are low at hospital level (mean score 1.6 on a scale of 0 to 5, SD 0.7), but even lower at departmental level (mean 0.6, SD 0.7). We did not detect associations between levels of involving patients and their representatives in QM functions and the implementation of patient-centred care strategies; however, the smallest hospitals were more likely to have implemented patient-centred care strategies. CONCLUSIONS: There is insufficient evidence that involving patients and their representatives in QM leads to establishing or implementing strategies and procedures that facilitate patient-centred care; however, lack of evidence should not be interpreted as evidence of no effect.

OBJECTIVE: Clinical management is hypothesized to be critical for hospital management and hospital performance. The aims of this study were to develop and validate professional involvement scales for measuring the level of clinical management by physicians and nurses in European hospitals. DESIGN: Testing of validity and reliability of scales derived from a questionnaire of 21 items was developed on the basis of a previous study and expert opinion and administered in a cross-sectional seven-country research project 'Deepening our Understanding of Quality improvement in Europe' (DUQuE). SETTING AND PARTICIPANTS: A sample of 3386 leading physicians and nurses working in 188 hospitals located in Czech Republic, France, Germany, Poland, Portugal, Spain and Turkey. MAIN OUTCOME MEASURES: Validity and reliability of professional involvement scales and subscales. RESULTS: Psychometric analysis yielded four subscales for leading physicians: (i) Administration and budgeting, (ii) Managing medical practice, (iii) Strategic management and (iv) Managing nursing practice. Only the first three factors applied well to the nurses. Cronbach's alpha for internal consistency ranged from 0.74 to 0.86 for the physicians, and from 0.61 to 0.81 for the nurses. Except for the 0.74 correlation between 'Administration and budgeting' and 'Managing medical practice' among physicians, all inter-scale correlations were <0.70 (range 0.43-0.61). Under testing for construct validity, the subscales were positively correlated with 'formal management roles' of physicians and nurses. CONCLUSIONS: The professional involvement scales appear to yield reliable and valid data in European hospital settings, but the scale 'Managing medical practice' for nurses needs further exploration. The measurement instrument can be used for international research on clinical management.

OBJECTIVE: To explore how European hospitals have implemented patient safety strategies (PSS) and evidence-based organization of care pathway (EBOP) recommendations and examine the extent to which implementation varies between countries and hospitals. DESIGN: Mixed-method multilevel cross-sectional design in seven countries as part of the European Union-funded project 'Deepening our Understanding of Quality improvement in Europe' (DUQuE). SETTING AND PARTICIPANTS: Seventy-four acute care hospitals with 292 departments managing acute myocardial infarction (AMI), hip fracture, stroke, and obstetric deliveries. Main outcome measure Five multi-item composite measures-one generic measure for PSS and four pathway-specific measures for EBOP. RESULTS: Potassium chloride had only been removed from general medication stocks in 9.4-30.5% of different pathways wards and patients were adequately identified with wristband in 43.0-59.7%. Although 86.3% of areas treating AMI patients had immediate access to a specialist physician, only 56.0% had arrangements for patients to receive thrombolysis within 30 min of arrival at the hospital. A substantial amount of the total variance observed was due to between-hospital differences in the same country for PSS (65.9%). In EBOP, between-country differences play also an important role (10.1% in AMI to 57.1% in hip fracture). CONCLUSIONS: There were substantial gaps between evidence and practice of PSS and EBOP in a sample of European hospitals and variations due to country differences are more important in EBOP than in PSS, but less important than within-country variations. Agencies supporting the implementation of PSS and EBOP should closely re-examine the effectiveness of their current strategies.

Rationale: Chronic obstructive pulmonary disease (COPD) is a common comorbidity among patients with lung cancer, and an important determinant of their outcomes, however, it is commonly underdiagnosed. Objective: Our objective was to estimate the prevalence of COPD among a cohort of U.S. lung cancer patients, the timing of a COPD diagnosis relative to their lung cancer diagnosis, and the association between an earlier diagnosis of COPD and stage of lung cancer, with consideration of patient sociodemographic modifying factors. Methods: We conducted an analysis of the Medicare-linked Surveillance, Epidemiology, and End Results database including patients aged 68+ years who were diagnosed with lung cancer between 2008 to 2017. Exposure: Prevalence of COPD was identified using claims and subclassified based on the timing of its diagnosis relative to the lung cancer diagnostic episode-"preexisting" if diagnosed > 3 months before lung cancer, and "concurrent" if diagnosed around the same time as the lung cancer (+/-3 months). Outcome: The stage of cancer at diagnosis (early versus late) was the outcome. Results: Among 159,542 patients with lung cancer, 73.5% had COPD. Among those with COPD, 34.4% were diagnosed within 3 months of their lung cancer diagnosis and considered to have "concurrent COPD." We observed a positive association between preexisting COPD diagnosis and early-stage lung cancer (prevalence ratio= 1.27; 95% confidence interval= 1.23-1.30), in adjusted models which were stronger for male, non-Hispanic Black, and Hispanic patients. Conclusions: Seven out of 10 patients with lung cancer have COPD, however, many do not receive their COPD diagnosis until around the time of their lung cancer diagnosis. Among these patients, an early COPD diagnosis may improve early detection of lung cancer.
RESUMEN
BACKGROUND: Internationally, 20% to 50% of cancer is diagnosed through emergency presentation, which is associated with lower survival, poor patient experience, and socioeconomic disparities, but population-based evidence about emergency diagnosis in the United States is limited. We estimated emergency department (ED) involvement in the diagnosis of cancer in a nationally representative population of older US adults, and its association with sociodemographic, clinical, and tumor characteristics. METHODS: We analyzed Surveillance, Epidemiology, and End Results Program-Medicare data for Medicare beneficiaries (≥66 years old) with a diagnosis of female breast, colorectal, lung, and prostate cancers (2008-2017), defining their earliest cancer-related claim as their index date, and patients who visited the ED 0 to 30 days before their index date to have "ED involvement" in their diagnosis, with stratification as 0 to 7 or 8 to 30 days. We estimated covariate-adjusted associations of patient age, sex, race and ethnicity, marital status, comorbidity score, tumor stage, year of diagnosis, rurality, and census-tract poverty with ED involvement using modified Poisson regression. RESULTS: Among 614â748 patients, 23% had ED involvement, with 18% visiting the ED in the 0 to 7 days before their index date. This rate varied greatly by tumor site, with breast cancer at 8%, colorectal cancer at 39%, lung cancer at 40%, and prostate cancer at 7%. In adjusted models, older age, female sex, non-Hispanic Black and Native Hawaiian or Other Pacific Islander race, being unmarried, recent year of diagnosis, later-stage disease, comorbidities, and poverty were associated with ED involvement. CONCLUSIONS: The ED may be involved in the initial identification of cancer for 1 in 5 patients. Earlier, system-level identification of cancer in non-ED settings should be prioritized, especially among underserved populations.
