RESUMEN

This data article describes a dataset of US CEO turnover types created with manual data collection through searches of news stories related to CEO turnover. The data identify the fiscal year of turnover and its type for top managers in publicly-traded US firms. Researchers in economics, finance and accounting explore the role of CEO turnover in various settings, however data on the timing and type of CEO departures are not always reliably available. We identify turnover cases based on changes in the CEO of the firm as recorded in secondary data sources of Compustat and Execucomp, and then we classify turnover types based on the examination of full-text news. By including data on company and executive identifiers, this dataset may be merged with existing finance and accounting databases and used in future research on a variety of topics. The data includes 3,100 US publicly-traded firms and may be used in both cross-sectional and longitudinal analyses.

RESUMEN

BACKGROUND: Portal vein thrombosis is a potentially devastating complication following pediatric liver transplantation. In rare instances of complete portomesenteric thrombosis, cavoportal hemitransposition may provide graft inflow. Here we describe long-term results following a case of pediatric cavoportal hemitransposition during liver transplantation and review the current pediatric literature. METHODS: A 9-month-old female with a history of biliary atresia and failed Kasai portoenterostomy underwent living donor liver transplantation, which was complicated by portomesenteric venous thrombosis. The patient underwent retransplantation with cavoportal hemitransposition on postoperative day 12. OUTCOME: The patient recovered without further complication, and 10 years later, she continues to do well, with normal graft function and no clinical sequelae of portal hypertension. CT scan with 3-D vascular reconstruction demonstrated recanalization of the splanchnic system, with systemic drainage to the inferior vena cava via an inferior mesenteric vein shunt. The cavoportal anastomosis remains patent with hepatopetal flow. Of the 12 previously reported cases of pediatric cavoportal hemitransposition as portal inflow in liver transplantation, this is the longest-known follow-up with a viable allograft. Notably, sequelae of portal hypertension were also rare in the 12 previously reported cases, with no cases of long-term renal dysfunction, lower extremity edema, or ascites. CONCLUSIONS: Long-term survival beyond 10 years with normal graft function is feasible following pediatric cavoportal hemitransposition. Complications related to portal hypertension were generally short-lived, likely due to the development of robust collateral circulation. Additional reports of long-term outcomes are necessary to facilitate informed decision making when considering pediatric cavoportal hemitransposition for liver graft inflow.

RESUMEN

BACKGROUND: Inaccuracy of clinical staging renders management of clinical T2 N0 M0 (cT2 N0 M0) esophageal cancer difficult. When an underlying advanced-stage disease is understaged to cT2 N0 M0, patients miss the opportunity to gain the potential benefits of neoadjuvant therapy. This study aimed to identify preoperative factors that predict underlying advanced-stage esophageal cancer. METHODS: From 2000 to 2020, 1579 patients with esophageal cancer underwent esophagectomy. Sixty patients who underwent upfront surgery for cT2 N0 M0 esophageal cancer were included in this study. The median age was 62.5 years, and 78% (n = 47) of these patients were male. Radiologic, clinical, and endoscopic factors were evaluated as preoperative markers. The Fisher exact and the Wilcoxon rank sum tests were used for categoric and continuous variables, respectively. Random forest classification was used to identify preoperative factors for predicting upstaging and downstaging. RESULTS: Of the 60 patients, 8 (13%) were found to have pathologic T2 N0 M0 esophageal cancer. Sixteen (27%) patients had cancer that was pathologically downstaged, and 36 (60%) had upstaged disease. Seven (19%) patients had upstaged cancer on the basis of the pathologic T stage, 14 (39%) had upstaging on the basis of the pathologic N stage, and 15 (42%) had upstaging on the basis of both T and N stages. Dysphagia (P = .003) and tumor maximum standardized uptake value (P = .048) were predictors of upstaging, with a combined predictive value of up to 75%. CONCLUSIONS: The presence of dysphagia and of high maximum standardized uptake value (≥5) of the tumor is predictive of more advanced underlying disease for patients with cT2 N0 M0 esophageal cancer, and these patients should be considered for neoadjuvant therapy.

RESUMEN

BACKGROUND: Open approaches for esophagectomy are often still useful; of these, left thoracoabdominal esophagectomy (TAE) is poorly understood and often criticized. Hence, we examined TAE's worldwide utilization, survival, and present-day use and outcomes at our institution compared with contemporary national averages. METHODS: The Worldwide Esophageal Cancer Collaboration database includes 8854 patients who underwent esophagectomy for cancer between 2005 and 2014, a period when TAE was our center's most common approach. Two propensity score-matched models were constructed: worldwide TAE vs worldwide non-TAE (751 matched pairs); and our high-volume center TAE vs worldwide non-TAE (273 matched pairs). All-cause mortality was compared between matched groups. Institutional TAE data from 2017 to 2021 were assessed for present-day use and outcomes. RESULTS: Worldwide, propensity score-matched patients undergoing TAE had a median of 20 lymph nodes resected vs 17 after non-TAE (P < .0001). Five-year survival was 34% for worldwide TAE vs 42% for worldwide non-TAE groups (P = .04). Three-year matched survival was 52% for high-volume TAE compared with 54% for worldwide non-TAE groups (P = .1). From 2017 to 2021 at our institution, 90 (26%) of 346 esophagectomies were performed by TAE. Pneumonia developed in 5 patients (5.6%), with 88 patients (98%) alive at 30 days, comparable to contemporary averages of The Society of Thoracic Surgeons. CONCLUSIONS: When it is performed as the primary approach in high volumes, TAE can have comparable outcomes to non-TAE with low morbidity. At present, we find that TAE is most useful in patients with truncal obesity, prior abdominal operations, and locally advanced cardia tumors with potential for variable extent of resection.

RESUMEN

Bilateral transverse thoracosternotomy, or "clamshell" thoracotomy, can be complicated by dehiscence. A 65-year-old male underwent lung transplantation via clamshell thoracotomy, with subsequent sternal dehiscence on postoperative day 11. Upon repair, the previous sternal wires had pulled through, so a Sternal Talon connected to a Recon Talon was utilized to re-approximate the inferior sternum. On follow-up at 3 months, the patient recovered well. Use of the Sternal Talon provides an effective technique for repairing transverse sternal dehiscence.

RESUMEN

OBJECTIVE: Currently, there is no validated patient-reported outcome measure (PROM) applicable to all esophageal diseases. Our objective was to create a psychometrically robust, validated universal esophageal PROM that can also objectively assess patients' quality of life (QoL). METHODS: The pilot PROM constructed based on expert opinions, literature review, and previous unpublished institutional research had 27 items covering 8 domains. It was completed by 30 patients in the outpatient clinic followed by a structured debriefing interview, which allowed for refining the PROM. The final PROM: Cleveland Clinic Esophageal Questionnaire (CEQ) included 34 items across 6 domains (Dysphagia, Eating, Pain, Reflux & Regurgitation, Dyspepsia, Dumping), each accompanied by a corresponding QoL component. Further psychometric assessment of the PROM was conducted by evaluating (1) acceptability, (2) construct validity, (3) reliability, and (4) responsiveness. RESULTS: Five hundred forty-six unique patients (median 63.7 years [54.3-71.7], 53% male [287], 86% White) completed CEQ at >90% completion within 5 minutes. Construct validity was demonstrated by differentiating scores across esophageal cancer (n = 146), achalasia (n = 170), hiatal hernia (n = 160), and other diagnoses (n = 70). Internal reliability (Cronbach alpha 0.83-0.89), and test-retest reliability (intraclass correlation coefficients 0.63-0.85) were strong. Responsiveness was demonstrated through CEQ domains improving for 53 patients who underwent surgery for achalasia or hiatal hernia (Cohen d 0.86-2.59). CONCLUSIONS: We have constructed a psychometrically robust, universal esophageal PROM that allows concise, consistent, objective quantification of symptoms and their effect on the patient. The CEQ is valuable in prognostication and tracking of longitudinal outcomes in both benign and malignant esophageal diseases.

RESUMEN

BACKGROUND: Type I achalasia comprises 20% of achalasia and has nearly absent esophageal motor activity. Concerns that fundoplication decreases the effectiveness of Heller myotomy in these patients has increased adoption of peroral endoscopic myotomy (POEM). Hence, we compared outcomes after Heller myotomy with Dor fundoplication vs POEM. METHODS: From 2005 to 2020, 150 patients with type I achalasia underwent primary surgical myotomy (117 Heller myotomy, 33 POEM). Patient demographics, prior treatments, timed barium esophagrams, Eckardt scores, and reinterventions were assessed between the 2 groups. Median follow-up was 5 years for Heller myotomy and 2.5 years for POEM. RESULTS: The Heller myotomy group was younger, had fewer comorbidities, and lower body mass index vs POEM. Risk-adjusted models demonstrated clinical success (Eckardt ≤3) in 83% of Heller myotomies and 87% of POEMs at 3 years; longitudinal complete timed barium esophagram emptying and reintervention were also similar. An abnormal pH test result was documented in 10% (6 of 60) after Heller myotomy and in 45% (10 of 22) after POEM (P < .001). CONCLUSIONS: Despite nearly absent esophageal contractility, Heller myotomy with Dor fundoplication and POEM result in similar long-term symptom relief, esophageal emptying, and occurrence of reintervention in patients with type I achalasia. There is decreased esophageal acid exposure with the addition of a fundoplication, without compromised esophageal drainage, allaying fears of a detrimental effect of a fundoplication. Hence, choice of procedure may be personalized based on patient characteristics and esophageal morphology and not solely on manometric subtype.

RESUMEN

OBJECTIVES: We hypothesized that emergency complications related to asymptomatic paraconduit hernias may occur less often than generally believed. Therefore, we assessed the occurrence and timing of paraconduit hernia diagnosis after esophagectomy, as well as outcomes of these asymptomatic patients managed with a watch-and-wait approach. METHODS: From 2006 to 2021, 1214 patients underwent esophagectomy with reconstruction at the Cleveland Clinic. Among these patients, computed tomography scans were reviewed to identify paraconduit hernias. Medical records were reviewed for timing of hernia diagnosis, hernia characteristics, and patient symptoms, complications, and management. During this period, patients with asymptomatic paraconduit hernias were typically managed nonoperatively. RESULTS: Paraconduit hernias were identified in 37 patients. Of these, 31 (84%) had a pre-esophagectomy hiatal hernia. Twenty-one hernias (57%) contained colon, 7 hernias (19%) contained pancreas, and 9 hernias (24%) contained multiple organs. Estimated prevalence of paraconduit hernia was 3.3% at 3 years and 7.7% at 10 years. Seven patients (19%) had symptoms, 4 of whom were repaired electively, with 2 currently awaiting repairs. No patient with a paraconduit hernia experienced an acute complication that required emergency intervention. CONCLUSIONS: The risk of paraconduit hernia increases with time, suggesting that long-term symptom surveillance is reasonable. Emergency complications as a result of asymptomatic paraconduit hernias are rare. A small number of patients will experience hernia-related symptoms, sometimes years after hernia diagnosis. Our findings suggest that observation of asymptomatic paraconduit hernias (watch and wait) may be considered, with repair considered electively in patients with persistent symptoms.

RESUMEN

OBJECTIVES: The purpose of this study was to examine the number of exacerbations, counts of eosinophils, and asthma-related symptoms 1 year before and after initiating benralizumab for the treatment of severe eosinophilic asthma. METHODS: Patients with prior exacerbations and newly initiating benralizumab were identified in the claims-based Healthcare Integrated Research Database. Claims were used to assess benralizumab treatment patterns, exacerbations, healthcare resource utilization, and other asthma medication used. Among a subset of patients, medical records were abstracted for Asthma Control Test (ACT) scores and asthma symptoms. RESULTS: There were 506 patients meeting inclusion/exclusion criteria for claims-based analyses and 123 for medical-record analyses. The number of patients experiencing exacerbations significantly decreased from baseline to follow-up (40% reduction, McNemar's χ2 = 204.00, p < .001). The mean number of exacerbations also decreased from 3.2 (1.5) to 1.2 (1.4) (paired t = 24.45, p < .001; Cohen's D = 1.09). The effects were larger among patients with eosinophils ≥300 cells/µL. Among patients with an ACT available for baseline and follow-up (n = 47), there was a significant reduction in the number of patients with scores <19 (72% vs. 45%, p < .01). CONCLUSIONS: Treatment with benralizumab resulted in fewer exacerbations, reduced utilization, and improved ACT scores. This study demonstrates that benralizumab is an effective treatment option for patients with severe eosinophilic asthma.

RESUMEN

OBJECTIVE: Spread through air spaces (STAS) is a new histologic feature of invasion of non-small cell lung cancer that lacks sensitivity and specificity on frozen sections and is associated with higher recurrence and worse survival with sublobar resections. Our objective is to identify preoperative characteristics that are predictive of STAS to guide operative decisions. METHODS: From January 2018 through December 2021, 439 cT1-3N0 M0 patients with non-small cell lung cancer and a median age of 68 years, 255 (58%) women, who underwent primary surgery at our institution were included. Patients who received neoadjuvant therapy and whose STAS status was not documented were excluded. Age, sex, smoking status, tumor size, ground-glass opacities, maximum standardized uptake values, and molecular markers on preoperative biopsy were evaluated as preoperative markers. Comparisons between groups were conducted using standardized mean differences and random forest classification was used for prediction modeling. RESULTS: Of the 439 patients, 177 had at least 1 STAS-positive tumor, and 262 had no STAS-positive tumors. Overall, 179 STAS tumors and 293 non-STAS tumors were evaluated. Younger age (50 years or younger), solid tumor, size ≥2 cm, and maximum standardized uptake value ≥2.5 were independently predictive of STAS with prediction probabilities of 50%, 40%, 38%, and 40%, respectively. STAS tumors were more likely to harbor KRAS mutations and be PD-L1 negative. CONCLUSIONS: Young age (50 years or younger), larger (≥2 cm) solid tumors, high maximum standardized uptake values, and presence of KRAS mutation, are risk factors for STAS and can be considered for lobectomy. Smoking status and gender are still controversial risk factors for STAS.

RESUMEN

This study explores whether the sensitivity of CEO compensation to changes in firm performance depends on the CEO's likelihood of leaving the position. In a sample of 3180 US publicly-traded firms, we find that the sensitivity of bonus pay to firm performance is enhanced for a CEO who has reached retirement age. Further, we find that the sensitivity of bonus pay to firm performance is greater when there is evidence of a planned CEO turnover within a two-year window. We show that these findings are consistent with a principal-agent model in which firms who anticipate a greater likelihood of CEO departure find it advantageous to enhance the link between bonus pay and concurrent performance measures to compensate for the lowering of incentives that rely on the manager being employed long-term. The results provide a rationale for including bonus pay in the overall executive compensation package.

RESUMEN

BACKGROUND: Esophageal morphology in achalasia is thought to affect outcomes, with "end-stage" sigmoidal morphology faring poorly; however, evaluation of morphology's role in outcomes has been limited by lack of objective characterization. Hence, the goals of this study were twofold: characterize the variability of timed barium esophagram (TBE) interpretation and evaluate an objective classification of TBE tortuosity: length-to-height ratio (LHR). We hypothesized that the esophagus must elongate to become sigmoidal such that sigmoidal morphology would demonstrate a larger LHR. METHODS: Ninety pre-operative TBEs were selected from an institutional database. Esophageal morphology was categorized as straight, intermediate, or sigmoidal. Esophageal length was measured by a mid-lumen line from the aortic knob to the esophagogastric junction on TBE; height was measured vertically from the aortic knob to the level of the esophagogastric junction. The length divided by the height generated the LHR. Descriptive statistics and frequency of expert agreement were calculated. Median LHR was compared between consensus morphologies. A receiver operating characteristic (ROC) determined the optimal LHR for sigmoidal vs non-sigmoidal characterization. RESULTS: From a total of 90 pre-operative TBEs, expert consensus morphology was reached in 56 (62.2%) cases. Pairs of experts agreed on morphology in 62-74% of TBEs, with all three experts agreeing on 46.7-48.9% of cases. Median LHR between expert consensus morphologies was 1.03, 1.09, and 1.24 for straight, intermediate, and sigmoidal morphologies, respectively (p < 0.001). ROC demonstrated that an LHR cutoff of 1.13 was 100% sensitive and 95% specific (AUC 0.99) for ruling out sigmoidal morphology. CONCLUSION: These findings confirm our anecdotal experience that subjective morphology interpretation is variable, even between experts at a high-volume center. LHR provides an objective method for classification, allowing us to overcome the limitations of inter-observer variability, thus paving the way for future study of the role of morphology in achalasia outcomes.

RESUMEN

BACKGROUND: Several small studies reported high risk of progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) in Barrett's esophagus (BE) patients who undergo solid organ transplantation (SOT) and implied that this may be due to immunosuppressant use. However, the major shortcoming of these studies was the lack of a control population. Therefore, we aimed to determine the rates of neoplastic progression in BE patients who underwent SOT and compare to that in controls and identify the predictors of progression. METHODS: This was a retrospective cohort study of BE patients seen in Cleveland Clinic and affiliated hospitals between January 2000 and August 2022. Demographics, endoscopic and histological findings, history of SOT and fundoplication, immunosuppressant use, and follow-up were abstracted. RESULTS: The study population consisted of 3466 patients with BE, of which 115 had SOT (lung 35, liver 34, kidney 32, heart 14, and pancreas 2) and 704 patients on chronic immunosuppressants but no history of SOT. During a median follow-up of 5.1 years, there was no difference in the annual risk of progression between the three groups (SOT=0.61%, no SOT but on immunosuppressants= 0.82%, and no SOT/no immunosuppressants= 0.94%, p=0.72). On multivariate analysis, immunosuppressant use (odds ratio (OR) 1.38, 95% confidence interval (CI) 1.04-1.82, p=0.025) but not SOT (OR 0.39, 95%CI 0.15-1.01, p=0.053) was associated with neoplastic progression in BE patients. CONCLUSION: Immunosuppression is a risk factor for progression of BE to HGD/EAC. Therefore, close surveillance of BE patients on chronic immunosuppressants needs to be considered.

RESUMEN

BACKGROUND: Venous thromboembolism (VTE) is a significant cause of morbidity and mortality in patients with lung cancer. Systemic therapies, such as chemotherapy (chemo), are associated with increased risk of VTE. Immune checkpoint inhibitors (ICIs) are a new standard of care for the treatment of lung cancer, but their association with VTE is not fully understood. We evaluated the incidence of VTE and risk factors for patients with advanced non-small cell lung cancer (aNSCLC) treated with first-line ICI-based, chemo-based, or ICI+chemo regimens. METHODS: This retrospective cohort study used HealthCore Integrated Research Environment - Oncology data, an integrated database of administrative claims, coupled with clinical data from a cancer-care quality program. Patients with first-line treatment of stage IV non-small cell lung cancer from July 2014 to August 2020 were grouped based on three treatment types: ICI-based, chemo-based, or ICI+chemo. Patients with VTE before initiation of systemic treatment were excluded. Newly diagnosed VTE events were identified via inpatient and outpatient diagnosis codes. Cox proportional hazards models were used to investigate the factors associated with VTE risk. RESULTS: Among 2299 eligible patients (ICI-based, n=605; chemo-based, n=1092; ICI+chemo, n=602) with a median follow-up of 9.1 months, the VTE incidence rates (95% CI) per 100 person-years were 17.8 (95% CI 16.0 to 19.5) overall, 13.5 (95% CI 10.6 to 16.5) for ICI-based, 18.0 (95% CI 15.5 to 20.5) for chemo-based, and 22.4 (95% CI 20.2 to 24.5) for ICI+chemo. The 6-month cumulative incidence of VTE was 8.1% for ICI-based, 10.9% for chemo-based, and 12.8% for ICI+chemo. Pulmonary embolism was most common, accounting for 63% of the VTE events. After controlling for baseline patient characteristics, the risk of VTE was 26% lower for ICI-based regimens than for chemo-based regimens (HR 0.74, p=0.03). There was no meaningful difference in the risk between ICI+chemo and chemo-based regimens (HR 1.12, p=0.36). Previous radiation and severe obesity (body mass index ≥40) were associated with VTE. CONCLUSIONS: VTE incidence rate per 100 person-years was common across regimens in patients with aNSCLC, but numerically lower for patients receiving ICI-based regimens compared with those receiving chemo-based and ICI+chemo regimens. VTE is a common complication of lung cancer, and there is a continued need for awareness of VTE as a comorbidity in this population.

RESUMEN

The legalization of the cultivation of low Δ9-tetrahydrocannabinol (Δ9-THC) and high cannabidiol (CBD) Cannabis Sativa plants is gaining momentum around the world due to increasing demand for CBD-containing products. In many countries where CBD oils, extracts and CBD-infused foods and beverages are being sold in health shops and supermarkets, appropriate testing of these products is a legal requirement. Normally this involves determining the total Δ9-THC and CBD and their precursor tetrahydrocannabinolic acids (THCA) and cannabidiolic acid (CBDA). As our knowledge of the other relevant cannabinoids expands, it is likely so too will the demand for them as additives in many consumer products ensuring a necessity for quantification methods and protocols for their identification. This paper discusses therapeutically relevant cannabinoids found in Cannabis plant, the applicability and efficiency of existing extraction and analytical techniques as well as the legal requirements for these analyses.

RESUMEN

OBJECTIVE: Guidelines for optimal frequency of screening mammography vary by professional society. Sparse evidence exists on the association between screening frequency and breast cancer treatment options. The main objective was to examine differences in cancer treatment rendered for U.S. women with different numbers of screenings prior to breast cancer diagnosis. Cancer stage at diagnosis and health care cost were assessed in secondary analyses. METHODS: This IRB-exempt retrospective study used administrative claims data to identify women aged 44 or older with various numbers of mammographic screenings ≥11 months apart, during the four years prior to incident breast cancer diagnosis from January 2010 to December 2018. Outcomes were assessed over the six months following diagnosis. Generalized linear regression models were used to compare women with differing numbers of mammograms, adjusting for patient characteristics. RESULTS: Claims data review identified 25 492 women who met inclusion criteria. There was a stepwise improvement in each of these screening categories such that women with four screenings, compared to women with only one screening, experienced higher rates of lumpectomy (70% vs 55%) and radiation therapy (48% vs 36%), lower rates of mastectomy (27% vs 34%) and chemotherapy (28% vs 36%), less stage 3 or 4 cancer at diagnosis (15% vs 29%), and lower health care costs within six months postdiagnosis (P < 0.001). Results were similar in a subgroup limited to women aged 44 to 49 at diagnosis. CONCLUSION: Potential benefits of more frequent screening include less aggressive treatment and lower health care costs among women who develop breast cancer.

RESUMEN

Background: Diaphragmatic hernias with strangulated contents are a surgical challenge. Thoracoabdominal incisions are commonly used for a variety of thoracic and vascular cases, although rarely used for diaphragmatic hernias, which are typically repaired with laparotomy, thoracotomy, or minimally invasive approaches. Case report: We present the unique case of a 60-year-old, critically ill unstable patient with severe heart failure with a reduced ejection fraction (15-25%) and severe valve disease presenting with a left-sided diaphragmatic hernia containing strangulated small intestine and requiring urgent surgical exploration. This was safely and efficiently repaired via a thoracoabdominal approach at the index surgery, with intestines left in discontinuity and placement of temporary chest and abdominal closure. At the second planned operation, good continuity was successfully restored. Results: The patient had early extubation, gradual diet advancement with full recovery, and discharge home on postoperative day 17. Conclusion: A thoracoabdominal incision can safely be used in large strangulated diaphragmatic hernias, including in critically unstable patients. This approach provides rapid access to both the chest and abdomen with excellent, speedy, and safe exposure, which can save a life in extreme conditions.

RESUMEN

PURPOSE: The integration of pharmacies with oncology practices-known as medically integrated dispensing or in-office dispensing-could improve care coordination but may incentivize overprescribing or inappropriate prescribing. Because little is known about this emerging phenomenon, we analyzed historical trends in medically integrated dispensing. METHODS: Annual IQVIA data on oncologists were linked to 2010-2019 National Council for Prescription Drug Programs pharmacy data; data on commercially insured patients diagnosed with any of six common cancer types; and summary data on providers' Medicare billing. We calculated the national prevalence of medically integrated dispensing among community and hospital-based oncologists. We also analyzed the characteristics of the oncologists and patients affected by this care model. RESULTS: Between 2010 and 2019, the percentage of oncologists in practices with medically integrated dispensing increased from 12.8% to 32.1%. The share of community oncologists in dispensing practices increased from 7.6% to 28.3%, whereas the share of hospital-based oncologists in dispensing practices increased from 18.3% to 33.4%. Rates of medically integrated dispensing varied considerably across states. Oncologists who dispensed had higher patient volumes (P < .001) and a smaller share of Medicare beneficiaries (P < .001) than physicians who did not dispense. Patients treated by dispensing oncologists had higher risk and comorbidity scores (P < .001) and lived in areas with a higher % Black population (P < .001) than patients treated by nondispensing oncologists. CONCLUSION: Medically integrated dispensing has increased significantly among oncology practices over the past 10 years. The reach, clinical impact, and economic implications of medically integrated dispensing should be evaluated on an ongoing basis.
