Identifying Opportunities to Deliver High-Quality Cancer Care Across a Health System: A Clinical Responsibility

OBJECTIVE

We examined process-related quality metrics for oral squamous cell carcinoma (OSCC) depending on treating facility type across a health system and region.

STUDY DESIGN

Retrospective in accordance with Strengthening the Reporting of Observational Studies in Epidemiology guidelines.

SETTING

Single health system and region.

METHODS

Patients with OSCC diagnosed between 2012 and 2018 were identified from tumor registries of 6 hospitals (1 academic and 5 community) within a single health system. Patients were categorized into 3 care groups: (1) solely at the academic center, (2) solely at community facilities, and (3) combined care at academic and community facilities. Primary outcome measures were process-related quality metrics: positive surgical margin rate, lymph node yield (LNY), adjuvant treatment initiation ≤6 weeks, National Comprehensive Cancer Network (NCCN)-guideline adherence.

RESULTS

A total of 499 patients were included: 307 (61.5%) patients in the academic-only group, 101 (20.2%) in the community-only group, and 91 (18.2%) in the combined group. Surgery at community hospitals was associated with increased odds of positive surgical margins (11.9% vs 2.5%, odds ratio [OR]: 47.73, 95% confidence interval [CI]: 11.2-275.86, P < .001) and lower odds of LNY ≥ 18 (52.8% vs 85.9%, OR: 0.15, 95% CI: 0.07-0.33, P < .001) relative to the academic center. Compared with the academic-only group, odds of adjuvant treatment initiation ≤6 weeks were lower for the combined group (OR: 0.30, 95% CI: 0.13-0.64, P = .002) and odds of NCCN guideline-adherent treatment were lower in the community only group (OR: 0.35, 95% CI: 0.18-0.70, P = .003).

CONCLUSION

Quality of oral cancer care across the health system and region is comparable to or better-than national standards, indicating good baseline quality of care. Differences by facility type and fragmentation of care present an opportunity for bringing best in-class cancer care across an entire region.

Impact of Cancer Care Regionalization on Patient Volume

BACKGROUND

Cancer centers are regionalizing care to expand patient access, but the effects on patient volume are unknown. This study aimed to compare patient volumes before and after the establishment of head and neck regional care centers (HNRCCs).

METHODS

This study analyzed 35,394 unique new patient visits at MD Anderson Cancer Center (MDACC) before and after the creation of HNRCCs. Univariate regression estimated the rate of increase in new patient appointments. Geospatial analysis evaluated patient origin and distribution.

RESULTS

The mean new patients per year in 2006-2011 versus 2012-2017 was 2735 ± 156 patients versus 3155 ± 207 patients, including 464 ± 78 patients at HNRCCs, reflecting a 38.4 % increase in overall patient volumes. The rate of increase in new patient appointments did not differ significantly before and after HNRCCs (121.9 vs 95.8 patients/year; P = 0.519). The patients from counties near HNRCCs, showed a 210.8 % increase in appointments overall, 33.8 % of which were at an HNRCC. At the main campus exclusively, the shift in regional patients to HNRCCs coincided with a lower rate of increase in patients from the MDACC service area (33.7 vs. 11.0 patients/year; P = 0.035), but the trend was toward a greater increase in out-of-state patients (25.7 vs. 40.3 patients/year; P = 0.299).

CONCLUSIONS

The creation of HNRCCs coincided with stable increases in new patient volume, and a sizeable minority of patients sought care at regional centers. Regional patients shifted to the HNRCCs, and out-of-state patient volume increased at the main campus, optimizing access for both local and out-of-state patients.

Effect of Hospital Safety Net Burden on Survival for Patients With Sinonasal Squamous Cell Carcinoma

OBJECTIVE

To examine factors associated with hospital safety net burden and its impact on survival for patients with sinonasal squamous cell carcinoma (SNSCC).

STUDY DESIGN

Retrospective database study.

SETTING

National Cancer Database from 2004 to 2016.

METHODS

SNSCC cases were identified in the National Cancer Database. Hospital safety net burden was defined by percentage of uninsured/Medicaid patients treated, namely ≤25% for low-burden hospitals, 26% to 75% for medium-burden hospitals, and >75% for high-burden hospitals (HBHs). Univariate and multivariate analyses were used to investigate patient demographics, clinical characteristics, and overall survival.

RESULTS

An overall 6556 SNSCC cases were identified, with 1807 (27.6%) patients treated at low-burden hospitals, 3314 (50.5%) at medium-burden hospitals, and 1435 (21.9%) at HBHs. On multivariate analysis, Black race (odds ratio [OR], 1.39; 95% CI, 1.028-1.868), maxillary sinus primary site (OR, 1.31; 95% CI, 1.036-1.643), treatment at an academic/research program (OR, 20.63; 95% CI, 8.868-47.980), and treatment at a higher-volume facility (P < .001) resulted in increased odds of being treated at HBHs. Patients with grade III/IV tumor (OR, 0.70; 95% CI, 0.513-0.949), higher income (P < .05), or treatment modalities other than surgery alone (P < .05) had lower odds. Survival analysis showed that hospital safety net burden status was not significantly associated with overall survival (log-rank P = .727).

CONCLUSION

In patients with SNSCC, certain clinicopathologic factors, including Black race, lower income, treatment at an academic/research program, and treatment at facilities in the West region, were associated with treatment at HBHs. Hospital safety net burden status was not associated with differences in overall survival.

Trends in Cancer Treatment Service Availability Across Critical Access Hospitals and Prospective Payment System Hospitals

BACKGROUND

Rural residents experience worse cancer prognosis and access to cancer care providers than their urban counterparts. Critical access hospitals (CAHs) represent over half of all rural community hospitals. However, research on cancer services provided within CAHs is limited.

OBJECTIVE

The objective of this study was to investigate trends in cancer services availability in urban and rural Prospective Payment System (PPS) hospitals and CAHs.

DESIGN

Retrospective, time-series analysis using data from 2008 to 2017 American Hospital Association Annual Surveys. Multivariable logistic regressions were used to examine differential trends in cancer services between urban PPS, rural PPS, and CAHs, overall and among small (<25 beds) hospitals.

SUBJECTS

All US acute care and cancer hospitals (4752 in 2008 to 4722 in 2017).

MEASURES

Primary outcomes include whether a hospital provided comprehensive oncology services, chemotherapy, and radiation therapy each year.

RESULTS

In 2008, CAHs were less likely to provide all cancer services, especially chemotherapy (30.4%) and radiation therapy (2.9%), compared with urban (64.4% and 43.8%, respectively) and rural PPS hospitals (42.0% and 23.3%, respectively). During 2008-2017, compared with similarly sized PPS hospitals, CAHs were more likely to provide oncology services and chemotherapy, but with decreasing trends. Radiation therapy availability between small PPS hospitals and CAHs did not differ.

CONCLUSIONS

Compared with all PPS hospitals, CAHs offered fewer cancer treatment services and experienced a decline in service capability over time. These differences in chemotherapy services were mainly driven by hospital size, as small urban and rural PPS hospitals had lower rates of chemotherapy than CAHs. Still, the lower rates of radiotherapy in CAHs highlight disproportionate challenges facing CAHs for some specialty services.

Trends in Cancer Treatment for Oral Cavity, Oropharynx, and Larynx in 2016 Versus 2009: SEER Patterns of Care Studies

PURPOSE

To determine if there was a higher percentage of patients treated surgically and with advanced radiotherapy in 2016 (N = 897) versus 2009 (N = 1136), the patient and tumor characteristics associated with surgical care and advanced radiotherapy, and if chemotherapy or targeted agent use varied over time for squamous cell carcinoma of the head and neck.

METHODS

We utilized Surveillance Epidemiology and End Results Patterns of Care datasets. Rao-Scott Chi-square tests and logistic regressions were applied to determine differences in surgery, advanced radiotherapy (RT), and chemotherapy by year.

RESULTS

There was a lower prevalence of surgery only treatment in 2016 versus 2009 with exception of oral cavity stages IVB/IVC and unknown, and larynx stage unknown. Advanced RT was more common in 2016 for patients receiving definitive RT among all sites, excluding stages I/II glottic larynx. Among each site (oral cavity, oropharynx, and larynx) lower stage was associated with increased odds of surgery. Among each site, advanced RT was more common in patients receiving definitive versus postoperative RT. For the larynx site, 2016 versus 2009 was associated with greater odds of advanced RT. Systemic treatment with fluorouracil, taxanes, or cetuximab was less prevalent in 2016.

CONCLUSION

In 2016 versus 2009, there was largely not a higher percentage of patients treated surgically. There was a higher prevalence of advanced RT for definitive care. Further investigations of these patterns are needed, including trend analysis.

Temporal Trends and Regionalization of Acute Mastoiditis Management in the United States

OBJECTIVE

To describe demographics and to analyze temporal trends in the inpatient management of acute mastoiditis admissions.

STUDY DESIGN

Cross-sectional analysis.

SETTING

National Inpatient Sample, 2002-2014.

PATIENTS

26,072 nonelective inpatient admissions with primary diagnosis of acute mastoiditis.

INTERVENTION

Myringotomy, mastoidectomy, or no procedure.

MAIN OUTCOME MEASURES

We described the patient- and hospital-level demographics of acute mastoiditis admissions and the frequency of complications. We evaluated the percentage of patients requiring surgical management. Binary logistic regression was performed to determine whether there was a significant increase in the percentage of patients treated at academic institutions.

RESULTS

The majority of patients were ≤40 years old (64.9%) and Elixhauser comorbidity index ≥4 (57.4%); 23.3% (SE 0.8%) presented with complications associated with acute mastoiditis, the most common of which was a subperiosteal abscess (11.5%, SE 0.7%). Among all admissions, 30.9% (SE 1.1%) underwent myringotomy, 13.8% (SE 0.8%) required both myringotomy and mastoidectomy. On multivariate analysis, there was a statistically significant increase in the percentage of mastoiditis admissions to teaching hospitals for all admissions (OR 1.55 [CI 1.22-1.97], p < 0.001) and even more evident for cases with associated complications (OR 1.85 [CI 1.21-2.83], p = 0.004).

CONCLUSIONS AND RELEVANCE

A sizeable percentage of patients with acute mastoiditis present with complications which may require surgical intervention. From 2002 to 2014, inpatient care of acute mastoiditis became increasingly regionalized to teaching hospitals, suggestive of increased specialization within certain facilities. This trend may have significant impacts on the cost and subsequent quality of care provided to these patients.

Impact of payer status and hospital volume on outcomes after head and neck oncologic reconstruction

BACKGROUND

High-volume centers improve outcomes in head and neck cancer (HNCA) reconstruction, yet it is unknown whether patients of all payer status benefit equally.

METHODS

We identified patients undergoing HNCA surgery between 2002 and 2015 using the National Inpatient Sample. Outcomes included receipt of care at high-volume centers, receipt of reconstruction, and post-operative complications. Multivariate regression analysis was stratified by payer status.

RESULTS

37,442 patients received reconstruction out of 101,204 patients who underwent HNCA surgery (37.0%). Privately-insured and Medicaid patients had similar odds of receiving high-volume care (OR = 0.99, 95% CI = 0.87-1.11) and undergoing reconstruction (OR = 0.96, 95% CI = 0.86-1.05). Medicaid beneficiaries had higher odds of complication (OR = 1.36, 95% CI = 1.22-1.51). The discrepancy in complication odds was significant at low-volume (OR = 1.44, 95% CI = 1.12-1.84) and high-volume centers (OR = 1.30, 95% CI = 1.15-1.47).

CONCLUSIONS

Medicaid beneficiaries are as likely to receive care at high-volume centers and undergo reconstruction as privately-insured individuals. However, they have poorer outcomes than privately-insured individuals at both low- and high-volume centers.

Evaluation of early oral cavity cancer treatment quality at a single institution

OBJECTIVE

To evaluate the adherence to oral cavity quality guidelines endorsed by the American Head and Neck Society (AHNS) at a large tertiary care hospital.

METHODS

This retrospective study identified patients treated for early-stage oral tongue squamous cell carcinoma at a tertiary care hospital from 1992 to 2013. Patient charts were reviewed for 26 process quality measures and four key indicator process quality measures as endorsed by the AHNS. Patients were then grouped by diagnosis date either before (historical group, 1992-2007) or after (current treatment group, 2008-2013) the published process quality measures from the AHNS. Descriptive statistics were used to evaluate the rates of adherence for each process quality measure within the 2 groups.

RESULTS

Of the 57 patients identified, 29 were female (51%). The mean age was 62.3 years. A majority of the oral cavity cancers were stage I (59.6%), followed by stage II (35.1%) and stage III (5.3%). Compliance with the process quality measures was in the acceptable range in both cohorts. However, several areas demonstrated lower adherence in both cohorts. Statistically significant improvements were noted between the two cohorts, which showed a measurable improvement in adherence to process quality measures in several key areas over time.

CONCLUSION

Using the process quality measures proposed by the AHNS, adherence to the process quality measures for early-stage oral cavity cancer care at a tertiary care center was successfully evaluated. In general, good compliance with the proposed process quality measures was found and several areas for improvement were identified.

Impact of the insurance type of head and neck cancer patients on their hospitalization utilization patterns

BACKGROUND

Head and neck cancer (HNC) patients with Medicaid, Medicare, or no insurance show poor outcomes in comparison with privately insured patients. It was hypothesized that nonprivate insurance coverage biases the selection of the treatment site to favor hospitals that are not associated with optimum treatment outcomes. This study assessed the relation between the insurance type of HNC patients and the hospital type for inpatient care.

METHODS

Adult HNC patients were identified from the Nationwide Inpatient Sample (2012 and 2013). The primary exposure was the insurance provider type. The outcome was the hospital type, which was classified by the hospital's ownership and its location and teaching status. Multivariate multinomial logistic regression models were constructed to control for the patient's age, sex, race, income, mortality risk, and geographic location. The analysis was weighted and was adjusted for multiple comparisons.

RESULTS

In all, 37,466 HNC patients representing 187,330 patients nationally were identified. After adjustments for age, sex, race, income, and mortality risk, in comparison with privately insured patients, Medicaid, Medicare, and uninsured patients demonstrated 1.14 to 2.29 increased odds of undergoing treatment at rural, urban nonteaching, private investor-owned, or government (nonfederal) hospitals (P < .05). This trend remained apparent even after adjustments for the geographic location.

CONCLUSIONS

Uninsured patients or patients insured by government programs predominantly underwent care for HNC at hospital types most often associated with inferior survival outcomes. This finding could explain some proportion of insurance-related disparities in HNC outcomes. Further studies are warranted to determine whether interventions to promote equitable access to optimal hospital settings for patients, regardless of their insurance type, might improve outcomes among nonprivate insurance holders.

Differences in Survival With Surgery and Postoperative Radiotherapy Compared With Definitive Chemoradiotherapy for Oral Cavity Cancer: A National Cancer Database Analysis

Importance

Because locally advanced oral cavity squamous cell carcinoma (OCSCC) is often treated with surgery followed by postoperative radiotherapy (S+PORT), the effectiveness of organ preservation with concurrent chemoradiotherapy (CRT) remains unclear.

Objective

To compare the differences in survival between patients with locally advanced OCSCC treated with S+PORT or CRT.

Design, Setting, and Participants

Using the National Cancer Database, this study compared 6900 patients with stage III to IVA OCSCC treated with S+PORT and CRT from 2004 through 2012 at academic and community-based cancer clinics. Comparisons were made using Kaplan-Meier methods and Cox proportional hazards regression models using the entire cohort and a propensity score-matched cohort of 2286 patients.

Main Outcomes and Measures

Overall survival (OS).

Results

Of the 6900 study patients, 4809 received S+PORT (3080 male [64.0%] and 1792 [36.0%] female) and 2091 received CRT (1453 male [69.5%] and 638 [30.5%] female). Median follow-up for the entire group was 23.0 months overall but was shorter for patients receiving CRT (17.3-month) vs S+PORT (25.6 months). Patients receiving CRT were more likely to be older than 60 years, treated before 2007, live within 10 miles of the treating facility, treated at nonacademic centers, have more comorbidities, have T3 to T4a tumors, and have N2a to N2c nodal disease. Propensity score matching identified cohorts of patients with similar clinical variables. S+PORT was associated with improved survival among all patients (3-year OS: 53.9% for S+PORT vs 37.8% for CRT; difference = 16.1%; 95% CI, 13.6%-18.6%) and in the propensity score-matched cohort (3-year OS: 51.8% for S+PORT vs 39.3% for CRT; difference = 11.9%; 95% CI, 7.8%-16.0%). S+PORT was associated with improved survival among patients with T3 to T4a tumors (3-year OS: 49.7% for S+PORT vs 36.0% for CRT; difference = 16.1%; 95% CI, 13.6%-18.6%) but was not associated with improved survival among patients with T1 to T2 tumors (3-year OS: 59.1% for S+PORT vs 53.5% for CRT; difference = 5.6%; 95% CI, -3.1% to 14.3%).

Conclusions and Relevance

Compared with CRT, S+PORT was associated with improved survival for locally advanced OCSCCs, especially in T3 to T4a disease. These data support the use of surgery as the initial treatment modality for operable OCSCCs.

Quality Indicators for Head and Neck Oncologic Surgery

Objectives

to determine national benchmarks for established quality indicators in head and neck cancer (HNCA) surgery, focusing on differences between academic and nonacademic institutions.

Study Design

Cross-sectional analysis of national database.

Subjects and Methods

HNCA surgery admissions from the 2009-2011 Nationwide Inpatient Sample were analyzed for preoperative characteristics and postoperative outcomes. Multivariate analyses were used to identify factors influencing quality indicators after HNCA surgery. Quality metrics—including length of stay (LOS), inpatient death, return to the operating room (OR), wound infection, and transfusion—were compared for academic versus nonacademic institutions.

Results

A total of 38,379 HNCA surgery inpatient admissions (mean age, 56.5 years; 52.4% male) were analyzed (28,288 teaching vs 10,091 nonteaching). Nationally representative quality metrics for HNCA surgery were as follows: mean LOS, 4.26 ± 0.12 days; return to OR, 3.3% ± 0.2%; inpatient mortality, 0.7% ± 0.1%; wound infection rate, 0.9% ± 0.1%; wound complication rate, 4.3% ± 0.2%; and transfusion rate, 4.3% ± 0.3%. HNCA surgery patients at teaching hospitals had a greater proportion of males, radiation history, and high-acuity procedures and greater comorbidity scores (all P < .001). Multivariate analyses adjusting for age, sex, income, payer, prior radiation, comorbidity scores, and procedural acuity demonstrated that teaching hospitals had a slightly increased LOS (+0.30 days; P = .009) and odds ratio for wound infection (1.54; 95% CI: 1.22-1.94) versus nonteaching hospitals. There were no significant differences in return to OR ( P = .271), inpatient mortality ( P = .686), or transfusion rate ( P = .960).

Conclusion

Despite caring for substantially more complex HNCA surgery patients with greater comorbidities, teaching hospitals demonstrate only a marginally increased LOS and wound complication rate versus nonteaching hospitals, while other established quality metrics are similar.

Employment and return to work following chemoradiation in patient with HPV-related oropharyngeal cancer

Background

Human papillomavirus (HPV)-positive oropharyngeal cancer primarily affects working-age adults. Chemotherapy and radiation (CTRT) used to treat this disease may adversely impact a survivors' ability to work after treatment.

Methods

We surveyed participants with HPV-positive oropharyngeal cancer who completed CTRT regarding employment. We examined the associations between 1) sociodemographic and clinical factors and employment outcomes, and 2) health-related quality of life and satisfaction with ability to work.

Results

102 participants were employed full-time at diagnosis for pay and surveyed at a median of 23 months post-CTRT (range 12-57 months). The median age at diagnosis was 57 years (range 25-76 years). During CTRT, 8 % stopped working permanently, 89 % took time off or reduced responsibility but later returned, and 3 % reported no change. For those who took time off but returned, median time to return to work was 14.5 weeks. In multivariable analysis, younger age predicted for needing more than the median time off. At time of survey, 85 % participants were working, 7 % had retired, and 8 % were not working for other reasons. Seventeen percent of participants were not satisfied with their current ability to work, which was associated with poorer health-related quality of life and persistent treatment toxicities (p < 0.001).

Conclusions

CTRT interrupts employment in the majority of working patients with HPV-positive oropharyngeal cancer but most return. However, treatment-related toxicities might lead to dissatisfaction with ability to work.
