The Role of Physician Specialty in the Underutilization of Standard-of-Care Treatment Intensification in Patients With Metastatic Castration-sensitive Prostate Cancer.

PURPOSE: We evaluate utilization of treatment intensification of androgen deprivation therapy with androgen receptor pathway inhibitor/docetaxel for metastatic castration-sensitive prostate cancer patients across physician specialties. MATERIALS AND METHODS: This retrospective study identified patients with metastatic castration-sensitive prostate cancer in the Optum Research Database between 2014 and 2019. Adult men with ≥1 claim for metastatic disease within 90 days before or any time after the first prostate cancer claim who received androgen deprivation therapy were included. Physician specialty, determined from medical/pharmacy claims during each line of therapy, was categorized as urologist only, oncologist only, both (urologists and oncologists), or other (other specialties). Treatment intensification and patient characteristics were analyzed descriptively. RESULTS: Of 4,675 patients, 16% were treated by urologists only, 20% by oncologists only, 63% by both, and 1.1% by others. The most frequent first line of therapy was androgen deprivation therapy ± first-generation nonsteroidal antiandrogens (>50%). Androgen deprivation therapy + docetaxel use declined over time, while androgen deprivation therapy + androgen receptor pathway inhibitor use increased. Patients seen by oncologists or both were younger, had fewer comorbidities, and were likelier to receive treatment intensification compared to those treated by urologists. By 2019, however, treatment intensification remained <40% from oncologists only or both, and <15% from urologists only. In the second and third lines of therapy, androgen deprivation therapy + androgen receptor pathway inhibitor was the most prescribed regimen across specialties (>50%). CONCLUSIONS: Treatment intensification was underused in first lines of therapy across urology and oncology specialties despite evidence of improved survival. In subsequent lines, androgen deprivation therapy + androgen receptor pathway inhibitor was prescribed more frequently across specialties. These results underscore the need for earlier treatment intensification by urologists and oncologists.

Clinical and economic burden of chronic rhinosinusitis with nasal polyposis: A U.S. administrative claims analysis.

Background: Limited data exist on the clinical and economic burden of chronic rhinosinusitis with nasal polyposis (CRSwNP). Objective: To describe patient characteristics, health-care resource utilization (HCRU), and health-care costs among patients with CRSwNP with and without comorbid asthma (primary analysis) and with surgical management of nasal polyps (secondary analysis). Methods: This was a retrospective study of patients diagnosed with CRSwNP conducted using administrative claims data from January 1, 2013, through March 31, 2019. Study outcomes were assessed over a 2-year follow-up. Results were stratified by baseline asthma status (primary analysis) and presented separately for patients with surgically managed CRSwNP (secondary analysis). Results: The primary analysis included 10,999 patients with CRSwNP (2649 with asthma, 8350 without asthma). Patients with versus without asthma had higher medication use, HCRU, and all-cause medical costs (mean ± standard deviation $34,667 ± $42,234 versus $27,122 ± $45,573; p < 0.001) across the full follow-up period. CRSwNP-related medical costs were significantly higher for patients with versus without asthma in year 2 of follow-up. In the surgical management analysis (n = 4943), most categories of medication use and CRSwNP-related HCRU declined from baseline levels during follow-up, and CRSwNP-related pharmacy costs in year 2 were less than half of baseline levels. Conclusion: Patients diagnosed with CRSwNP and asthma had a greater burden of illness than those without asthma. Higher CRSwNP-related medical costs in year 2 of follow-up for patients with asthma may indicate worsening symptoms over time. Among patients with surgically managed CRSwNP, HCRU and costs increased in year 1 of follow-up but decreased below baseline levels in year 2, potentially reflecting improved symptom severity.

Uptake and Utilization of Practice Guidelines in Hospitals in the United States: the Case of Routine Episiotomy.

BACKGROUND: The gap between publishing and implementing guidelines differs based on practice setting, including hospital geography and teaching status. On March 31, 2006, a Practice Bulletin published by the American College of Obstetricians and Gynecologists (ACOG) recommended against the routine use of episiotomy and urged clinicians to make judicious decisions to restrict the use of the procedure. OBJECTIVE: This study investigated changes in trends of episiotomy use before and after the ACOG Practice Guideline was issued in 2006, focusing on differences by hospital geographic location (rural/urban) and teaching status. METHODS: In a retrospective analysis of discharge data from the Nationwide Inpatient Sample (NIS)-a 20% sample of US hospitals-5,779,781 hospital-based births from 2002 to 2011 (weighted N = 28,067,939) were analyzed using multivariable logistic regression analysis to measure odds of episiotomy and trends in episiotomy use in vaginal deliveries. RESULTS: The overall episiotomy rate decreased from 20.3% in 2002 to 9.4% in 2011. Across all settings, a comparatively larger decline in episiotomy rates preceded the issuance of the ACOG Practice Guideline (34.0% decline), rather than following it (23.9% decline). The episiotomy rate discrepancies between rural, urban teaching, and urban nonteaching hospitals remained steady prior to the guideline's release; however, differences between urban nonteaching and urban teaching hospitals narrowed between 2007 and 2011 after the guideline was issued. CONCLUSION: Teaching status was a strong predictor of odds of episiotomy, with urban nonteaching hospitals having the highest rates of noncompliance with evidence-based practice. Issuance of clinical guidelines precipitated a narrowing of this discrepancy.
