The impact of facility type on surgical outcomes in colon cancer patients: analysis of the national cancer database.

BACKGROUND: The type of facility where patients with colon cancer are treated may play a significant role in their outcomes. We aimed to investigate the influence of facility types included in the National Cancer Database (NCDB) on surgical outcomes of colon cancer. METHODS: Retrospective cohort analysis of all patients with stage I-III colon cancer included in the NCDB database between 2010 and 2019 was performed. Patients were grouped based on facility type: Academic/Research Programs (ARP), Community Cancer Programs (CCP), Comprehensive Community Cancer Programs (CCCP), and Integrated Network Cancer Programs (INCP). Study outcomes included overall survival, 30- and 90-day mortality, 30-day readmission and conversion to open surgery. RESULTS: 125,935 patients were included with a median age of 68.7 years (50.5% females). Most tumors were in the right colon (50.6%). Patient were distributed among facility types as ARP (n = 34,321, 27%), CCP (n = 12,692, 10%), CCCP (n = 54,356, 43%), and INCP (n = 24,566, 19%). In terms of surgical approach, laparoscopy was more commonly used in ARP (46%) (p < 0.001). Laparotomy was more common in CCP (58.7%) (p < 0.001), and conversely, CCP had the least amount of robotic surgery (3.9%) (p < 0.001). Median overall survival was highest in ARP (129 months, 95% CI 127.4-134.1) and lowest in CCP (103.7 months, 95% CI 100.1-106.7) (p < 0.001). Conversion rates were comparable between ARP (12%), CCCP (12%) and INCP (11.8%) but were higher in CCP (15.5%) (p < 0.001). 30-day readmission rates and 30-day mortality rates were significantly lower in ARP compared to other facility types (p < 0.001). CONCLUSION: Our findings display differences in surgical outcomes of colon cancer patients among facility types. The findings suggest better outcomes in terms of operative access and survival at ARP as compared to other facilities. These findings underscore the importance of understanding facility-specific factors that may influence patient outcomes and can guide resource allocation and targeted interventions for improving colon cancer care.

Association of facility type with overall survival in patients with nonsurgically managed pancreatic cancer.

Aim: To investigate the association between receiving treatment at academic centers and overall survival in pancreatic ductal adenocarcinoma patients who do not receive definitive surgery of the pancreatic tumor. Methods: Using the National Cancer Database, patients who were diagnosed with pancreatic ductal adenocarcinoma between 2004 to 2016 were identified. Results: Of 262,209 patients, 101,003 (38.5%) received treatment at academic centers. In the multivariable Cox regression analysis, patients who received treatment at a nonacademic facility had significantly worse overall survival compared with patients who were treated at an academic center (hazard ratio: 1.279; 95% CI: 1.268-1.290; p = 0.001). Conclusion: Compared with treatment at academic centers, treatment at nonacademic centers was associated with significantly worse overall survival in patients with nonsurgically managed pancreatic ductal adenocarcinoma.

The aim of this study is to examine the association between receiving treatment at academic hospitals and overall survival in patients diagnosed with pancreatic cancer who do not receive definitive surgery of the pancreatic tumor. The authors used the National Cancer Database to identify patients who were diagnosed with pancreatic cancer between 2004 and 2016. The authors' study included 262,209 patients. The authors found that patients who received treatment at nonacademic hospitals were on average 28% more likely to die of any cause compared with patients who were treated at academic centers (hazard ratio: 1.279; 95% CI: 1.268­1.290; p < 0.001). Patients who received treatment at nonacademic hospitals were more likely to die of any cause compared with patients who received treatment at academic hospitals.

Type and case volume of health care facility influences survival and surgery selection in cases with early-stage non-small cell lung cancer.

BACKGROUND: With the expansion of non-small cell lung cancer (NSCLC) screening methods, the percentage of cases with early-stage NSCLC is anticipated to increase. Yet it remains unclear how the type and case volume of the health care facility at which treatment occurs may affect surgery selection and overall survival for cases with early-stage NSCLC. METHODS: A total of 332,175 cases with the American Joint Committee on Cancer (AJCC) TNM stage I and stage II NSCLC who were reported to the National Cancer Data Base (NCDB) by 1302 facilities were studied. Facility type was characterized in the NCDB as community cancer program (CCP), comprehensive community cancer program (CCCP), academic/research program (ARP), or integrated network cancer program (INCP). Each facility type was dichotomized further into high-volume or low-volume groups based on the case volume. Multivariate Cox proportional hazard models, the logistic regression model, and propensity score matching were used to evaluate differences in survival and surgery selection among facilities according to type and volume. RESULTS: Cases from ARPs were found to have the longest survival (median, 16.4 months) and highest surgery rate (74.8%), whereas those from CCPs had the shortest survival (median, 9.7 months) and the lowest surgery rate (60.8%). The difference persisted when adjusted by potential confounders. For cases treated at CCPs, CCCPs, and ARPs, high-volume facilities had better survival outcomes than low-volume facilities. In facilities with better survival outcomes, surgery was performed for a greater percentage of cases compared with facilities with worse outcomes. CONCLUSIONS: For cases with early-stage NSCLC, both facility type and case volume influence surgery selection and clinical outcome. Higher surgery rates are observed in facilities with better survival outcomes.

Increasing time to treatment initiation for head and neck cancer: an analysis of the National Cancer Database.

BACKGROUND: The objective of this study was to identify trends and predictors of the time to treatment initiation (TTI) for patients with head and neck squamous cell carcinoma (HNSCC). METHODS: The National Cancer Database (NCDB) was reviewed for the following head and neck cancer sites: oral tongue, oropharynx, larynx, and hypopharynx. TTI was defined as the number of days from diagnosis to the initiation of definitive treatment and was measured according to covariates. Significant differences in the median TTI across each covariate were measured using the Kruskal-Wallis test, and the Spearman test was used to measure trends within covariates. For multivariate analysis, a zero-inflated, negative, binomial regression model was used to estimate the expected TTI, which was expressed in the predicted number of days; and the Vuong test was used to identify the predictors of TTI. RESULTS: In total, 274,630 patients were included. Between 1998 and 2011, the median TTI for all patients was 26 days, and it increased from 19 days to 30 days (P < .0001). Treatment with chemoradiation (CRT) (P < .0001), treatment at academic facilities (P < .0001), and stage IV disease (P < .0001) were associated with increased TTI. TTI significantly increased for each disease stage (P < .0001), treatment modality (P < .0001), and facility type (P < .0001) over time. In addition, patients became more likely to transition care between facilities after diagnosis for treatment initiation (P < .0001) over time. On multivariate analysis, treatment at academic facilities (33 days), transitioning care (37 days), and receipt of CRT (39 days) predicted for a longer TTI. CONCLUSIONS: TTI is rising for patients with HNSCC. Those who have advanced-stage disease, receive treatment with CRT, are treated at academic facilities, and who have a transition in care realized the greatest increases in TTI.

Impact of facility type and volume in locally advanced esophageal cancer.

BACKGROUND: We hypothesized that academic facilities and high-volume facilities would be independently associated with improved survival and a greater propensity for performing surgery in locally advanced esophageal cancer. METHODS: We identified patients diagnosed with stage IB-III esophageal cancer during 2004-2016 from the National Cancer Database. Facility type was categorized as academic or community, and facility volume was based on the number of times a facility's unique identification code appeared in the dataset. Each facility type was dichotomized into high- and low-volume subgroups using the cutoff of 20 esophageal cancers treated/year. We fitted multivariable regression models in order to assess differences in surgery selection and survival between facilities according to type and volume. RESULTS: Compared to patients treated at high-volume community hospitals, those at high-volume academic facilities were more likely to undergo surgery (odds ratio: 1.865, p < 0.001) and were associated with lower odds of death (odds ratio: 0.784, p = 0.004). For both academic and community hospitals, patients at high-volume facilities were more likely to undergo surgery compared to those at low-volume facilities, p < 0.05. For patients treated at academic facilities, high-volume facilities were associated with lower odds of death (odds ratio: 0.858, p = 0.02) compared to low-volume facilities, while there was no significant difference in the odds of death between high- and low-volume community hospitals (odds ratio: 1.018, p = 0.87). CONCLUSIONS: Both facility type and case volume impact surgery selection and survival in locally advanced esophageal cancer. Compared to community hospitals, academic facilities were more likely to perform surgery and were associated with improved survival.

Disparities in Outcomes following Resection of Locally Advanced Rectal Cancer.

Surgical margins following rectal cancer resection impact oncologic outcomes. We examined the relationship between margin status and race, ethnicity, region of care, and facility type. Patients undergoing resection of a stage II-III locally advanced rectal cancer (LARC) between 2004 and 2018 were identified through the National Cancer Database. Inverse probability of treatment weighting (IPTW) was performed, with margin positivity rate as the outcome of interest, and race/ethnicity and region of care as the predictors of interest. In total, 58,389 patients were included. After IPTW adjustment, non-Hispanic Black (NHB) patients were 12% (p = 0.029) more likely to have margin positivity than non-Hispanic White (NHW) patients. Patients in the northeast were 9% less likely to have margin positivity compared to those in the south. In the west, NHB patients were more likely to have positive margins than NHW patients. Care in academic/research centers was associated with lower likelihood of positive margins compared to community centers. Within academic/research centers, NHB patients were more likely to have positive margins than non-Hispanic Other patients. Our results suggest that disparity in surgical management of LARC in NHB patients exists across regions of the country and facility types. Further research aimed at identifying drivers of this disparity is warranted.

The Impact of Facility Type and Volume on Outcomes in Head and Neck Mucosal Melanoma.

OBJECTIVE: To evaluate differences in treatment outcomes for head and neck mucosal melanoma (HNMM) patients seen at academic versus nonacademic centers and high versus low volume facilities. STUDY DESIGN: Retrospective cohort study. SETTING: National Cancer Database. METHODS: Differences in treatment course and overall survival (OS) by facility type and volume were assessed for 2772 HNMM cases reported by the 2004 to 2017 National Cancer Database. A subgroup analysis was performed with a smaller cohort containing staging data. The analysis employed Kaplan-Meier and Cox proportional hazards models. RESULTS: A higher proportion of patients treated at academic centers within the HNMM cohort waited longer for surgery after diagnosis (p < .001), had negative surgical margins (p < .001), and were readmitted to the hospital within 30 days of surgery (p = .001); these relationships remained significant when controlling for cancer stage. Kaplan-Meier analysis demonstrated higher 5-year OS for patients treated at academic versus nonacademic facilities within the main cohort (32.5% ± 1.3% vs 27.3% ± 1.5%; p = .006) and within the stage-controlled subgroup (34.8% ± 2.1% vs 27.2% ± 2.6%; p = .003). Treatment at high volume versus low volume facilities was associated with improved 5-year OS for main cohort patients (33.5% ± 1.7% vs 28.8% ± 1.2%; p = .016) but not for subgroup patients (35.3% ± 2.7% vs 30.1% ± 2.1%; p = .100). Upon multivariate analysis controlling for demographic and oncologic factors, there was no significant difference in OS by facility type (main cohort: odds ratio [OR] = 1.07, 95% confidence interval [CI] = 1.01-1.21; subgroup: OR = 1.13, 95% CI = 0.97-1.32). CONCLUSION: Neither facility type nor surgical volume predicts overall survival in HNMM.

Analysis of Concentrated COVID-19 Outbreaks in Elderly Facilities in Suita City, Osaka Prefecture, Japan.

There are several types of facilities for elderly individuals in Japan. Infection control efforts, such as care provision and medical care access, differ according to the type of facility. Elderly individuals at these facilities who were infected with coronavirus disease 2019 (COVID-19) experienced severe illness and mortality. This study aimed to determine the characteristics of concentrated COVID-19 outbreaks that occurred in nursing homes and care facilities in Suita City. During this study, twenty-five elderly facilities in Suita City with a capacity of 40 or more individuals where an outbreak occurred during the sixth or seventh wave of infection were included. We investigated whether there was a difference in the COVID-19 incidence and the percentage of positive cases according to the type of facility. We also investigated the relationship between the facility capacity and positive case rate and that between the number of positive cases and outbreak duration. The incidence rate of COVID-19 was significantly different according to the facility type (p < 0.001). No association was found between the facility capacity and positive case rate. The outbreak duration increased as the number of positive cases increased (p = 0.004).

Increases in CLIA-Waived Testing Sites Since the Start of the COVID-19 Pandemic.

The number of testing sites receiving their first Certificate of Waiver (CoW) under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) increased significantly after the start of the COVID-19 pandemic. We compared the first-time CoWs in 2020-2021 to those in 2018-2019. The total number of first-time CoWs during 2020-2021 was more than twice what it was in 2018-2019, corresponding to population testing needs during the COVID-19 pandemic, especially in assisted living facility, pharmacy, physician office, and school/student health service settings. This study highlighted the need to strengthen clinical testing strategies to be better prepared for future public health emergencies.

The road to recovery: impact of COVID-19 on healthcare utilization in South Korea in 2016-2022 using an interrupted time-series analysis.

Background: The COVID-19 pandemic substantially disrupted healthcare utilization patterns, globally. South Korea had been praised widely in its efforts to contain the spread of the pandemic, which may have contributed to a significantly smaller reduction in healthcare utilization compared to neighboring countries. However, it remains unknown how the COVID-19 pandemic impacted utilization patterns across population sub-groups, particularly vulnerable patient groups in South Korea. This paper quantifies the changes in healthcare utilization attributable to COVID-19 and the COVID-19 vaccination by sub-groups. Methods: An interrupted time series analysis was conducted to examine the impact of COVID-19 on healthcare utilization in South Korea from January 2016 to December 2022 using aggregated patient-level data from the national health insurance system that accounts for 99% of all healthcare services in South Korea. We applied negative binomial models adjusting for seasonality and serial correlation. Falsification tests were conducted to test the validity of breakpoints. Stratified analyses by type of healthcare services, age, sex, income level, health facility type, and avoidable/non-avoidable hospitalizations was performed, and we assessed differences in utilization trends between population groups across three phases of the pandemic. Findings: In early 2020, the COVID-19 pandemic caused a reduction in monthly volume of outpatient utilization by 15.7% [95% CI 13.3%-18.1%, p < 0.001] and inpatient utilization by 11.6% [10.1%-13.0%, p < 0.001]. Most utilization recovered and rebounded to pre-COVID-19 levels as of December 2022 although variations existed. We observed heterogeneity in the magnitude of relative changes in utilization across types of services, varying from a 42.7% [36.8%-48.0%, p < 0.001] decrease for pediatrics, a 23.4% [20.1%-26.5%%, p < 0.001] reduction in utilization of public health centers, and a 24.2% [21.2%-27.0%, p < 0.001] reduction in avoidable hospitalizations compared to the pre-pandemic period. Contrary to global trends, health utilization among the elderly population (65 and older) in South Korea saw only marginal reductions compared to other age groups. Similarly, Medicaid patients and lower income groups experienced a smaller reduction compared to higher income groups. Interpretation: The impact of the COVID-19 pandemic on healthcare utilization in South Korea was less pronounced compared to the global average. Utilization of vulnerable populations, including adults over 65 years old and lowest-income groups reduced less than other type of patients. Funding: No funding.

Social determinants and facility type impact adherence to best practices in operable IIIAN2 lung cancer.

OBJECTIVES: We aimed to identify patient- and facility-specific predictors of collective adherence to 4 recommended best treatment practices in operable IIIAN2 non-small-cell lung cancer (NSCLC) and test the hypothesis that collective adherence is associated with superior survival. METHODS: We queried the National Cancer Database for clinical stage IIIAN2 NSCLC patients undergoing surgery during 2010-2015. The following best practices were examined: performance of an anatomic resection, performance of an R0 resection, examination of regional lymph nodes and administration of induction therapy. Multivariable regression models were fitted to identify independent predictors of guideline-concordance. RESULTS: We identified 7371 patients undergoing surgical resection for IIIAN2 lung cancer, of whom 90.8% underwent an anatomic resection, 88.2% received an R0 resection, 92.5% underwent a regional lymph node examination, 41.6% received induction therapy and 33.7% received all 4 best practices. Higher income, private insurance and treatment at an academic facility were independently associated with adherence to all 4 best practices (P < 0.01). A lower level of education and residence in a rural county were associated with a lack of adherence (P < 0.05). Adherence to all 4 practices correlated with improved survival (P < 0.01). CONCLUSIONS: National adherence to best treatment practices in operable IIIAN2 lung cancer was variable as evidenced by the majority of patients not receiving recommended induction therapy. Socioeconomic factors and facility type are important determinants of guideline-concordance. Future efforts to improve outcomes should take this into account since guideline concordance, in the form of collective adherence to all 4 best practices, was associated with improved survival.

Treatment at a high-volume academic research program mitigates racial disparities in pancreatic adenocarcinoma.

BACKGROUND: Racial disparities have long been a subject of concern between patients afflicted with pancreatic cancer in the United States. We believe that, in addition to a high-volume center, treatment at an academic research program (ARP) will mitigate racial outcome disparities. METHODS: A total of 12,950 patients diagnosed with stage I-III pancreatic adenocarcinoma from 2003-2011 and at ACS Commission on Cancer (COC) accredited facilities [e.g., high-volume (≥12 cases/year) ARPs] were evaluated from the National Cancer Data Base (NCDB). Sociodemographic, clinicopathological, and treatment variables were compared between Black (N=1,127) and White (N=11,823) patients. The Kaplan-Meier Estimator and Cox Proportional Hazards Model were used for survival analysis. P value ≤0.05 was considered significant. RESULTS: Black patients had a significantly higher overall survival (OS) than White patients, despite having a significantly lower household income, lower education level, more stage III disease, more Medicaid recipients, and higher comorbidity index (P<0.05). The 5-year unadjusted OS (28.6% versus 23.9%, a median survival time (months) was (25.2 versus 23.7 months for Black and White patients, respectively (P<0.05). There was no significant difference in surgical margin status or receipt of chemoradiation between the two cohorts. After adjusting for covariates, race was no longer a significant predictor of OS (P=0.096). CONCLUSIONS: Treatment at a high volume, ARP can mitigate racial disparities in pancreatic cancer.

Adoption of single agent anticancer therapy for advanced hepatocellular carcinoma and impact of facility type, insurance status, and income on survival: Analysis of the national cancer database 2004-2014.

BACKGROUND: This study analyzes the pattern of use of single agent anticancer therapy (SAACT) in the treatment and survival of advanced hepatocellular carcinoma (aHCC) before and after sorafenib was FDA approved in 2007. METHODS: Adult patients diagnosed with HCC and treated with only ACT from 2004 - 2014 were identified in NCDB database. Patients were analyzed during three time frames: 2004-2006 (pre-sorafenib (PS)), 2007-2010 (early sorafenib (ES)) and 2011-2014 (late sorafenib (LS)). Cox proportional hazards models and Kaplan-Meier method were used for analyses. RESULTS: The NCDB contained 31,107 patients with HCC diagnosed from 2004-2014 and treated with ACT alone. Patients were generally men (78.0%), >50 years of age (92.5%). A significant increase in the rate of adaption of SAACT was observed over time: 6.2% PS, 15.2% ES, and 22.2% LS (p < 0.0001). During this later period, the highest proportion of SAACT is among academic and integrated network facilities (23.3%) as compared to community facilities (17.0%, p < 0.0001). The median overall survival of patients with aHCC treated only with SAACT improved significantly over time from 8.0 months (m) (95% CI: 7.4-8.8) to 10.7 m (10.4-11.2) to 15.6 m (15.2-16.0, p < 0.001). Multivariate analysis indicates worse outcomes for patients treated at community cancer programs (HR 1.28, (5% CI: 1.23-1.32), patients without insurance (HR 1.11, 1.06-1.16) and estimated household income of <$63,000 (HR 1.09, 1.05-1.13). CONCLUSION: aHCC patients treated only with ACT have experienced an overall improvement in survival, but significant differences exist between facility type, insurance status, and income.

The differential effect of the free maternity services policy in Kenya.

BACKGROUND: The Government of Kenya introduced the free maternity services (FMS) policy to enable mothers deliver at a health facility and thus improve maternal health indicators. AIM: The aim of this study was to determine if there was a differential effect of the policy by region (sub-county) and by facility type (hospitals vs. primary healthcare facilities [PHCFs]). SETTING: The study was conducted in Nyamira County in western Kenya. METHODS: This was an interrupted time series study where 42 data sets (24 pre- and 18 post-intervention) were collected for each observation. Monthly data were abstracted from the District Health Information System-2, verified, keyed into and analysed by using IBM-Statistical Package for the Social Sciences (SPSS-17). RESULTS: The relative effect of the policy on facility deliveries in the county was an increase of 22.5%, significant up to the 12th month (p < 0.05). The effect of the policy on deliveries by region was highest in Nyamira North and Masaba North (p < 0.001 up to the 18th month). The effect was larger (46.5% vs. 18.3%) and lasted longer (18 months vs. 6 months) in the hospitals than in the PHCFs. The increase in hospital deliveries was most significant in Nyamira North (61%; p < 0.001). There was a medium-term effect on hospital deliveries in Borabu (up to 9 months) and an effect that started in the sixth month in Manga. The relative effect of the policy on facility deliveries in PHCFs was only significant in Nyamira North and Masaba North (p < 0.001). CONCLUSION: The effect of the FMS policy was varied by region (sub-county) and by facility type.

Trends and Outcomes of Proton Radiation Therapy Use for Non-Small Cell Lung Cancer.

PURPOSE: To examine national care patterns in proton radiation therapy (PBT) use for non-small cell lung cancer (NSCLC) and the effect of facility type on survival. PATIENTS AND METHODS: Using the National Cancer Database, we identified 506 patients with a diagnosis of NSCLC from 2004-2014 who underwent PBT. Patients were categorized as having received treatment at an academic/research facility (ARF) or a form of community cancer program (CCP). Descriptive analysis was performed, and overall survival was analyzed by Kaplan-Meier methods and Cox proportional hazard models. RESULTS: Treatments at ARFs and CCPs were equally distributed with 253 patients at each facility type. A positive trend in PBT use over time was observed with 2.8% of cases being treated in 2008 compared to 21.5% in 2014 (P = .001). Definitive doses (≥60 Gy) were more commonly given at ARFs than CCPs (72% versus 45%, respectively; P < .001). Five-year overall survival was 31% at ARFs and 18% at CCPs (P < .001). On multivariate analysis, outcomes were worse with treatments at CCPs (hazard ratio [HR] 1.61; 95% Confidence Interval, 1.14-2.27; P = .007). On subanalysis of nonsurgical patients treated with ≥60 Gy, facility type became insignificant and dose escalation was associated with improved outcomes (≥70 Gy HR 0.45; 95% CI, 0.25-0.81; P = .008). CONCLUSION: Use of PBT for management of NSCLC is on the rise. Community cancer programs were associated with higher rates of nondefinitive PBT doses and correspondingly worse outcomes. Differences in survival by facility became insignificant when definitive doses were used, warranting further investigation of practice patterns in CCPs at a national level.

Comparison of facility type outcomes for oral cavity cancer: Analysis of the national cancer database.

OBJECTIVE: Determine whether facility type effects overall survival in patients with oral cavity cancer. STUDY DESIGN: Retrospective cohort study. METHODS: Patients included in the National Cancer Database who were diagnosed with oral cavity cancer between 1998 and 2011 were included in the study. Data was stratified by facility where care was provided, including community cancer programs (CCP), comprehensive community cancer programs (CCCP), and academic centers (AC). Univariate analysis was performed using analysis of variance, chi squared, and log-rank test, whereas multivariate analysis was performed using Cox regression. RESULTS: A total of 32,510 patients were included in the study, with 7.58% of patients receiving care at CCPs (n = 2,553), 39.53% at CCCPs (n = 12,852), and 52.61% at ACs (n = 17,105). Between 1998 and 2011, there was a greater percentage of patients receiving care at ACs, and a greater percentage of patients receiving surgical therapy versus nonsurgical therapy. Patients treated at ACs had the best 5-year overall survival of 51.26%, with a significant difference across facility types (P < 0.01). After adjusting for confounders, receiving care at ACs was a positive predictor of survival (hazard ratio: 0.95 95% confidence interval [0.91,0.98])). CONCLUSION: Patients treated at ACs are more likely to receive surgical treatment, and have a greater 5-year overall survival compared to those patients treated at CCPs and CCCPs. Therefore, we advocate referring patients with advanced oral cavity cancers to ACs. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:2551-2557, 2017.
