A population health assessment of screening mammography on breast cancer mortality in North Carolina.

PURPOSE: To identify predictors of screening mammography use and the effect of screening mammography on breast cancer mortality in North Carolina. METHODS: This cross-sectional study integrated publicly available data from government and private data repositories to model predictors of screening mammography and breast cancer mortality in North Carolina. RESULTS: In North Carolina during 2008-2010, on average, 68.1% of women aged 40-74 years underwent a screening mammogram in the previous two years (range: 38.7%-82.1). The ordinary least squares (OLS) regression demonstrated counties experiencing persistent poverty have mammography screening rates that are 4.3% less, on average, than counties without persistent poverty (estimate (SE) = - 4.283 (2.105), p = 0.045). As the percentage of women with a college education increases, the mammography screening rates increase by approximately 0.3% (estimate (SE) = 0.319 (0.078), P < .001) and as the health literacy score increases, the mammography screening rate decreases by 0.3% (estimate (SE) = - 0.318 (0.104), p = 0.003). These variables explain 7.0% of the variability in mammographic screening rates. The OLS regression analysis demonstrated that age-adjusted breast cancer incidence (Estimate (SE) = 0.074 (0.024), p = 0.003) and health literacy score (estimate (SE) = - 0.175 (0.083), p = 0.039) are significantly related to breast cancer mortality. CONCLUSIONS: Demographic, socioeconomic, and environmental variables explain only a small percentage of the variability in the rates of screening mammography and breast cancer mortality in North Carolina. Advances in the available treatments are likely the major contributor to improving breast cancer mortality.

Changes in the Proportion of Patients Presenting With Early Stage Colon Cancer Over Time Among Medicaid Expansion and Nonexpansion States: A Cross-sectional Study.

BACKGROUND: The 2010 Patient Protection and Affordable Care Act mandated preventive screening coverage and provided support to participating states for Medicaid coverage. The association of Medicaid expansion with colon cancer stage at diagnosis is unknown. OBJECTIVE: This study aimed to determine whether the proportion of patients diagnosed with early stage colon cancer changed over time within states that expanded Medicaid compared with nonexpansion states. DESIGN: This is a cross-sectional cohort study. SETTING: This study evaluated multicenter registry data from the National Cancer Database (2006-2016). PATIENTS: There were 25,462 uninsured or Medicaid-insured patients with newly diagnosed colon cancer who resided in 2014 Medicaid expansion or nonexpansion states. MAIN OUTCOME MEASURES: This study assessed the annual proportion of patients with early stage (I-II) versus late stage (III-IV) colon cancer. RESULTS: A total of 10,289 patients were identified in expansion states and 15,173 patients in nonexpansion states. Cohorts were similar in age (median 55 years) and sex (46.7% female). A greater proportion of patients in nonexpansion states were Black (33.4% vs 24.0%) and resided in a zip code with median income <$38,000 (39.7% vs 28.2%) and lower educational status (37.4% vs 28.1%). In 2006, the proportions of patients with early stage colon cancer in expansion and nonexpansion cohorts were similar (33.2% vs 32.5%). The proportion of patients with early stage colon cancer within nonexpansion states declined by 0.8% per year after 2014, whereas the proportion within expansion states increased by 0.9% per year after 2014 ( p < 0.05). By 2016, the absolute difference in the propensity-adjusted proportion of early stage colon cancer was 8.8% (39.7% vs 30.9%, p < 0.001). LIMITATIONS: National Cancer Database data are obtained only from Commission on Cancer-accredited sites and are not population based. CONCLUSIONS: After Medicaid expansion in 2014, the proportion of patients diagnosed and treated at Commission on Cancer-accredited facilities with early stage colon cancer increased within expansion states and decreased in nonexpansion states. Increase in insurance coverage may have facilitated earlier diagnosis among patients in expansion states. See Video Abstract at http://links.lww.com/DCR/B804 .

Development and Assessment of a Systematic Approach for Detecting Disparities in Surgical Access.

Importance: Although optimal access is accepted as the key to quality care, an accepted methodology to ascertain potential disparities in surgical access has not been defined. Objective: To develop a systematic approach to detect surgical access disparities. Design, Setting, and Participants: This cross-sectional study used publicly available data from the Health Cost and Utilization Project State Inpatient Database from 2016. Using the surgical rate observed in the 5 highest-ranked counties (HRCs), the expected surgical rate in the 5 lowest-ranked counties (LRCs) in North Carolina were calculated. Patients 18 years and older who underwent an inpatient general surgery procedure and patients who underwent emergency inpatient cholecystectomy, herniorrhaphy, or bariatric surgery in 2016 were included. Data were collected from January to December 2016, and data were analyzed from March to July 2020. Exposures: Health outcome county rank as defined by the Robert Wood Johnson Foundation. Main Outcomes and Measures: The primary outcome was the proportional surgical ratio (PSR), which was the disparity in surgical access defined as the observed number of surgical procedures in the 5 LRCs relative to the expected number of procedures using the 5 HRCs as the standardized reference population. Results: In 2016, approximately 1.9 million adults lived in the 5 HRCs, while approximately 246 854 lived in the 5 LRCs. A total of 28 924 inpatient general surgical procedures were performed, with 4521 being performed in those living in the 5 LRCs and 24 403 in those living in the 5 HRCs. The rate of general surgery in the 5 HRCs was 13.09 procedures per 1000 population. Using the 5 HRCs as the reference, the PSR for the 5 LRCs was 1.40 (95% CI, 1.35-1.44). For emergent/urgent cholecystectomy, the PSR for the 5 LRCs was 2.26 (95% CI, 2.02-2.51), and the PSR for emergent/urgent herniorrhaphy was 1.83 (95% CI, 1.33-2.45). Age-adjusted rate of obesity (body mass index [calculated as weight in kilograms divided by height in meters squared] greater than 30), on average, was 36.6% (SD, 3.4) in the 5 LRCs vs 25.4% (SD, 4.6) in the 5 HRCs (P = .002). The rate of bariatric surgery in the 5 HRCs was 33.07 per 10 000 population with obesity. For the 5 LRCs, the PSR was 0.60 (95% CI, 0.51-0.69). Conclusions and Relevance: The PSR is a systematic approach to define potential disparities in surgical access and should be useful for identifying, investigating, and monitoring interventions intended to mitigate disparities in surgical access that effects the health of vulnerable populations.

Lifetime cost-effectiveness of calcineurin inhibitor withdrawal after de novo renal transplantation.

After renal transplantation, immunosuppressive regimens associated with high short-term survival rates are not necessarily associated with high long-term survival rates, suggesting that regimens may need to be optimized over time. Calcineurin inhibitor (CNI) withdrawal from a sirolimus-based immunosuppressive regimen may maximize the likelihood of long-term graft and patient survival by minimizing CNI-associated nephrotoxicity. In this study, a lifetime Markov model was created to compare the cost-effectiveness of a sirolimus-based CNI withdrawal regimen (sirolimus plus steroids) with other common CNI-containing regimens in adult de novo renal transplantation patients. Long-term graft survival was estimated by renal function and data from published studies and the US transplant registry, including short- and long-term outcomes, utility weights, and health-state costs were incorporated. Drug costs were based on average daily consumption and wholesale acquisition costs. The model suggests that treatment with sirolimus plus steroids is more efficacious and less costly than regimens consisting of a CNI, mycophenolate mofetil, and steroids; therefore, CNI withdrawal not only shows potential for long-term clinical benefits but also is expected to be cost-saving over a patient's life compared with the most commonly prescribed CNI-containing regimens.

Pharmacy cost evaluation of risperidone, olanzapine, and quetiapine for the treatment of schizophrenia in acute care inpatient settings.

OBJECTIVE: This study examines total pharmacy cost and usage patterns of schizophrenic patients in acute mental health inpatient settings for three atypical antipsychotics -- risperidone, olanzapine, and quetiapine. Despite the readily available unit cost information for drugs, actual pharmacy costs may deviate significantly from 'labeled costs'. Recent research findings indicate the need for more robust evaluation of such pharmacy costs. RESEARCH DESIGN AND METHODS: This study used data from non-randomized inpatient retrospective charts from three acute care inpatient mental health facilities. The final pooled sample included 327 patients, of which 120 received risperidone, 153 received olanzapine, and 54 received quetiapine. Medication cost was defined as the average wholesale price (AWP) as listed in the 2001 'Red Book'. Propensity scoring methodology and multinomial regression were employed to reduce treatment selection bias. RESULTS: The observed mean daily antipsychotic drug doses were 4.45 mg (SD 2.44) for risperidone, 14.04 mg (SD 5.55) for olanzapine, and 350.33 mg (SD 228.24) for quetiapine. The corresponding mean daily drug costs were $7.66(SD $4.20) for risperidone, $8.11 (SD $5.29) for quetiapine and, $12.10 (SD $4.79) for olanzepine. Numbers adjusted for treatment selection bias show that the average daily total pharmacy cost of risperidone was $4.35 lower than olanzapine (p < 0.001) and $1.41 lower than quetiapine (p = 0.38). The adjusted average daily pharmacy cost of olanzapine was $4.02 higher than quetiapine (p < 0.001). After statistical adjustment there were no significant differences between study drugs in terms of length of stay or patient functioning. CONCLUSION: This study provides the first US comparison of medication utilization patterns and pharmacy costs for olanzapine, risperidone, and quetiapine administered in acute mental health care inpatient settings. While this study did not estimate the full economic value of the three antipsychotics in these inpatient settings, it demonstrated that the mean daily costs for risperidone were lower than the mean daily costs for olanzapine (p < 0.001) and quetiapine although the later difference was not statistically significant (p = 0.38).
