Background: There is a dearth of real-world evidence studies focused on allergy immunotherapy (AIT) use among patients with allergic rhinitis (AR). Objective: This study examined claims data of AR patients residing in the United States to assess patient characteristics and health outcomes. Methods: AR patients were identified in the IBM MarketScan database between January 1, 2014, and March 31, 2017. Patients receiving AIT were identified with relevant billing codes (earliest AIT claim for vaccine as the index date); patients without AIT were identified with claims that contained a diagnosis code for AR (earliest AR claim as the index date). All the patients were required to have continuous enrollment 12 months prior to and following their index date. AIT patients reaching 25+ injection claims were analyzed as a separate maintenance cohort. Patients were assessed for demographic characteristics, comorbid conditions, and health care utilization. Results: A total of 2,334,530 AR patients were included; 103,207 had at least one AIT claim, with 45,279 (43.9%) of these patients reaching maintenance. Patients who reached AIT maintenance presented higher rates of baseline comorbidities than both the full AIT cohort and the patients with no AIT claims, including asthma (34.6% versus 30.1% versus 7.5%) and upper respiratory tract infections (63.1% versus 60.3% versus 34.2%). From baseline to follow-up, maintenance AIT patients demonstrated reductions in all AR-related comorbidities assessed, along with reductions in all-cause and AR-related service utilization. Conclusion: Patients initiating AIT presented the greatest need for therapeutic intervention, as evidenced by higher allergy-related comorbidities; those who reached maintenance demonstrated improved outcomes following the initiation of therapy. Continued efforts to increase patient awareness and adherence to AIT are needed.

e18524 Background: The effective treatment of patients with acute myeloid leukemia (AML) remains a challenge in clinical practice. This analysis describes the patient characteristics and real-world use of AML treatments in the United States for patients on high- and low-intensity treatment. Methods: Data from the Adelphi AML Disease-Specific Programme, a real-world, cross-sectional survey conducted between February–May 2015, were analysed. A total of 61 hematologist/hem-oncologists, across academic, non-academic and office-based practice locations, provided data on 457 AML patients. Patient characteristics were derived from physician-completed patient record forms where each physician was asked to provide treatment details, including the treatment intensity, for each line of therapy. Results: A total of 91% (n = 415) of patients included in this analysis were previously untreated for AML. Patients had a mean age of 60 years and been diagnosed with AML for a median of 5.0 months. At first-line induction therapy, over half (53%; n = 241) of the patients were initiated on a high-intensity treatment, the most common regimen being cytarabine plus anthracycline (61%; n = 147). The remaining 47% (n = 216) of patients received a low-intensity induction therapy such as low dose cytarabine monotherapy (28%, n = 61), azacitidine monotherapy (25%, n = 54), or decitabine monotherapy (21%, n = 45). Over half (55%, n = 62) of patients suited to high intensity treatment went on to receive cytarabine monotherapy during the consolidation phase of their first-line treatment. Conclusions: According to treating physicians, the large majority of patients receive traditional, well-established therapies at first-line induction for AML. Whilst cytarabine combinations dominate the high-intensity treatment setting, the hypomethylating agents, azacitidine and decitabine, are frequently used for those more suited to low-intensity treatment.

Objectives Hospitalisation is frequently used as a marker of disease severity in observational Emergency Department (ED) studies. The comparison of ED admission rates is complex in potentially being influenced by the characteristics of the region, ED, physician and patient. We aimed to study variation in ED admission rates of febrile children, to assess whether variation could be explained by disease severity and to identify patient groups with large variation, in order to use this to reduce unnecessary health care utilization that is often due to practice variation. Design MOFICHE (Management and Outcome of Fever in children in Europe, part of the PERFORM study, www.perform2020.org), is a prospective cohort study using routinely collected data on febrile children regarding patient characteristics (age, referral, vital signs and clinical alarming signs), diagnostic tests, therapy, diagnosis and hospital admission. Setting and participants Data were collected on febrile children aged 0–18 years presenting to 12 European EDs (2017–2018). Main outcome measures We compared admission rates between EDs by using standardised admission rates after adjusting for patient characteristics and initiated tests at the ED, where standardised rates >1 demonstrate higher admission rates than expected and rates <1 indicate lower rates than expected based on the ED patient population. Results We included 38,120 children. Of those, 9.695 (25.4%) were admitted to a general ward (range EDs 5.1–54.5%). Adjusted standardised admission rates ranged between 0.6 and 1.5. The largest variation was seen in short admission rates (0.1–5.0), PICU admission rates (0.2–2.2), upper respiratory tract infections (0.4–1.7) and fever without focus (0.5–2.7). Variation was small in sepsis/meningitis (0.9–1.1). Conclusions Large variation exists in admission rates of febrile children evaluated at European EDs, however, this variation is largely reduced after correcting for patient characteristics and therefore overall admission rates seem to adequately reflect disease severity or a potential for a severe disease course. However, for certain patient groups variation remains high even after adjusting for patient characteristics.

49 Background: In May 2020, Olaparib was approved for HRRm mCRPC post progression on abiraterone and enzalutamide, and rucaparib was approved for BRCAm mCPRC following progression on androgen receptor targeted inhibitors and prior taxane therapy for mCRPC. HRRm are associated with approximately 25% of mCRPC and may be derived from germline or somatic origin. Somatic and germline alterations can be detected by tumour testing, but to differentiate between these, independent germline testing is needed. This study examined real-world genomic/genetic testing (GT) patterns in patients (pts) diagnosed with mCRPC in the United States (US). Methods: Data were drawn from the Adelphi Prostate Cancer Disease Specific Programme; a point-in-time survey administered to oncologists (onc), urologists (uro) and surgeons (sur) between January and August 2020 in the US. Physicians (phys) completed an attitudinal survey and a patient record form for the next four to nine mCRPC pts seen. Study variables included patient demographics, clinical factors and GT patterns. HRRm testers were defined as phys who tested for HRRm. Pts were identified as positive, negative or unknown depending on the outcome of the HRRm test. Results: A total of 72 phys (69% onc/ 29% uro/ 1% sur; 40% academic vs. 60% community) reported on 346 mCRPC pts. 41% of phys were based in the Northeast, 24% Midwest, 23% South and 13% in the West region of the US. 65 phys (90%) reported having access to overall GT; of these 5% identified as having access to germline tests only, while 94% were able to test for germline and somatic mutations. Challenges to conducting GT overall were ‘cost per test’ (50%), ‘having to send out for the tests (within country)’ (25%), ‘inadequate sample available’ (25%) and ‘patient refusal’ (25%). GT was typically conducted at identification of castrate-resistance (52%), metastases (51%) and at initial diagnosis (49%). 72% of total phys were HRRm testers; for these, patient characteristics primarily driving HRRm testing included Ashkenazi Jewish heritage (63%) and ECOG of 2-4 (58%). Other common drivers were family history, young diagnosis age and hormone therapy failure (all 46%). 132 (38% of 326) mCRPC pts were tested for HRRm; 39% of tested pts were identified with a HRRm. Most common HRRm tested were BRCA1 (90%), BRCA2 (89%) and ATM (55%). Conclusions: In this study majority of US phys had access to GT, but testing was only performed in 38% of pts with mCRPC. The higher than expected % of pts identified with an HRRm suggest that molecular testing was prioritised in high risk populations, as identified by the phys. With the recent approval of olaparib and rucaparib, GT may become more routine in clinical practice to identify eligible pts. Broader testing may also depend on addressing other barriers to testing including cost and testing logistics/practicalities.

Abstract Background Urinary tract infections (UTIs) are associated with significant morbidity and economic burden. Nitrofurantoin (NFT) and fosfomycin are among the first-line treatments for uncomplicated UTI (uUTI) recommended by Infectious Diseases Society of America (IDSA) 2011 guidance. We used real-world data (RWD) to assess patterns of appropriate and optimal (AP&OP) and inappropriate or suboptimal (IA/SO) antibiotic (AB) prescribing (RX), and related healthcare resource use (HRU) and costs, in US uUTI patients with high-risk comorbid conditions. Methods This was a retrospective cohort study of RWD (IBM MarketScan, commercial/Medicare Supplemental claims January 1, 2014–December 31, 2017) in females ≥ 12 years of age with uUTI, who had an oral AB prescription ± 5 days of uUTI diagnosis (index date) and continuous health-plan enrollment ≥ 1 year pre-/post-index date. Patients were stratified into high-risk cohorts (Table 1) and by AB RX (AP&OP and IA/SO) during first uUTI episode (within 28 days of index). AP&OP RX followed IDSA guidance, IA RX did not; SO RX was considered a proxy for treatment failure (e.g., AB switch or a second UTI diagnosis [acute care setting] in index episode). Sample size was balanced via random match selection, AP&OP:IA/SO ratio 1:5 (age and region). uUTIrelated HRU and costs were compared between cohorts (at index episode and 1-year follow-up) via multivariable analysis. Table 1. High-risk cohorts identified in the study Results IA/SO AB RX was highest in the elderly cohort (94.3%, likely influenced by renal impairment/no NFT RX in this group) and &gt; 90% in other cohorts; AP&OP AB RX was highest in the postmenopausal cohort (9.0%). IA/SO AB RX in all cohorts was associated with significantly higher uUTI-related HRU (outpatient visits and pharmacy claims) per index episode/during follow-up versus AP&OP AB RX (p ≤ 0.0237, Table 2). IA/SO AB RX in all cohorts was associated with significantly higher adjusted total costs per index episode/during follow-up versus AP&OP AB RX (p &lt; 0.05; Table 3). Table 2. uUTI-related HRU* per patient according to high-risk cohort and stratified by AB RX Table 3. uUTI-related costs* per patient according to high-risk cohort and stratified by AB RX Conclusion Over 90% of females in each high-risk cohort identified had IA/SO AB RX (outside IDSA 2011 guidance for uUTI treatment), leading to high HRU and cost burden. This suggests an unmet need for uUTI symptom relief, new treatments, training, and improved RX practices in the US and, furthermore, a need for additional research in this area.

BACKGROUND Significant variations in experience of the COVID-19 pandemic have been observed in the United States. However, there is currently no published study which comprehensively examines the relationship between patient characteristics and COVID-19 related health outcomes. OBJECTIVE In this study, using aggregated real-world data extracted from TriNetx electronic medical record data from 34 hospitals around United States, we intended to fill the gap. METHODS A total of 12,555 patients aged 18-80 years old who contracted COVID-19 were identified from January 20th to April 20th, 2020. RESULTS First, in the univariate analysis, we found that patients who were older (age 51-80), Black, male, and had pre-existing chronic diseases (e.g. obesity, diabetes, hypertension, and chronic kidney diseases (CKD)) had increased risk ratio (RR) of exhibiting severe outcomes, including increased C-reactive protein (CRP), decreased oxygen saturation, hospitalization, use of ventilator, and ultimately death. Next, we applied propensity score matching to match the patients based on their characteristics. We found that patients who were older, Black, male, and diagnosed with CKD had 3.69, 1.77, 1.75, and 1,61-fold increased RR of death. On the other hand, while obesity, diabetes, and hypertension had no direct relationship with death, they were associated with other severe outcomes. In further analysis by including CRP as a matching variable, death disparity by age group, race, gender, and CKD was reduced, particularly for race and CKD where a significant disparity was no longer observed. CONCLUSIONS In summary, our data show significant disparities in COVID-19 related outcomes by patient characteristics and further suggest that acute inflammation plays an important role in the disparity in COVID-19 death.

OBJECTIVETo characterize trends in outpatient antibiotic prescriptions in the United StatesDESIGNRetrospective ecological and temporal trend study evaluating outpatient antibiotic prescriptions from 2013 to 2015SETTINGNational administrative claims data from a pharmacy benefits manager PARTICIPANTS. Prescription pharmacy beneficiaries from Express Scripts Holding CompanyMEASUREMENTSAnnual and seasonal percent change in antibiotic prescriptionsRESULTSApproximately 98 million outpatient antibiotic prescriptions were filled by 39 million insurance beneficiaries during the 3-year study period. The most commonly prescribed antibiotics were azithromycin, amoxicillin, amoxicillin/clavulanate, ciprofloxacin, and cephalexin. No significant changes in individual or overall annual antibiotic prescribing rates were found during the study period. Significant seasonal variation was observed, with antibiotics being 42% more likely to be prescribed during February than September (peak-to-trough ratio [PTTR], 1.42; 95% confidence interval [CI], 1.39–1.61). Similar seasonal trends were found for azithromycin (PTTR, 2.46; 95% CI, 2.44–3.47), amoxicillin (PTTR, 1.52; 95% CI, 1.42–1.89), and amoxicillin/clavulanate (PTTR, 1.78; 95% CI, 1.68–2.29).CONCLUSIONSThis study demonstrates that annual national outpatient antibiotic prescribing practices remained unchanged during our study period. Furthermore, seasonal peaks in antibiotics generally used to treat viral upper respiratory tract infections remained unchanged during cold and influenza season. These results suggest that inappropriate prescribing of antibiotics remains widespread, despite the concurrent release of several guideline-based best practices intended to reduce inappropriate antibiotic consumption; however, further research linking national outpatient antibiotic prescriptions to associated medical conditions is needed to confirm these findings.Infect Control Hosp Epidemiol 2018;39:584–589

286 Background: RCC accounts for ~80%‒90% of all kidney cancers worldwide. The mRCC treatment landscape is rapidly changing with the approval of new therapies; data describing real-world (RW) treatment patterns and sequencing are limited. This study investigates the characteristics, treatment patterns, and sequencing for mRCC patients in the RW (December 2015‒May 2020) and post-dual immuno-oncology therapy (IO-IO) approval in the United States (April 2018‒May 2020). Methods: Adults diagnosed with mRCC between December 2015 and May 2020 were selected from the Flatiron electronic medical record database for this retrospective study. The study cohort was required to have ≥ 1 month of medical data from the initial mRCC diagnosis date (index date). We used descriptive statistics to analyze baseline patient characteristics, treatment patterns, and sequencing. Results: Of 3,524 patients with mRCC (overall cohort, December 2015–May 2020), most were male (68.5%) and had clear cell histology (68.2%). The median age at metastatic diagnosis was 68 years (range, 23–85) and the median follow-up from index date was 328 days. Based on IMDC risk score, 75.8% of patients were categorized as intermediate/poor risk and 23.2% as favorable risk (1% missing). Systemic therapy for RCC was initiated in 79.1% (N = 2788) of patients. The most common treatments for first-line (1L) therapy were tyrosine kinase inhibitor (TKI) monotherapy (mono; 56.4%), IO-IO (19.1%), IO-TKI (9.5%), IO mono (6.9%), and others (8.1%). Second-line (2L) therapy was received by 1303 patients; treatment sequences are presented in the table below. Among patients who received IO-based therapy in the 1L (N = 990), 11% were retreated with IO on any subsequent line. When stratified by clear cell and non-clear cell histology, similar treatment patterns and sequences were observed. Among patients who initiated 1L treatment post-April 2018 (N = 1395), the most common treatments for 1L therapy were IO-IO (36.9%) and TKI mono (32.7%). Among patients who received 2L treatment after initiating 1L post-April 2018 (N = 486), TKI mono followed by IO mono, and IO-IO followed by TKI mono were the most prescribed sequences (Table). Conclusions: Following approval of IO-based therapies for 1L, RW treatment patterns for mRCC are evolving; IO-IO has become the most common 1L therapy received by all patients initiating treatment for mRCC.
