Real-world risk assessment and treatment initiation among patients with myelofibrosis at community oncology practices in the United States.

ABSTRACT: Myelofibrosis (MF) is a chronic myeloproliferative neoplasm with a prevalence of 4 to 6 per 100,000 people in the USA. Treatment recommendations are risk-adapted. This study was conducted to evaluate how physicians risk-stratify patients at the time of MF diagnosis, the accuracy of the risk stratification, and its effect on treatment selection. Medical charts were reviewed at US community hematology/oncology practices in the Cardinal Health Oncology Provider Extended Network; patient clinical characteristics, risk stratification, and treatment data were collected. Physician-assigned risk categorizations were compared with data-derived risk categorizations based on the International Prognostic Scoring System, the system recommended at diagnosis. A total of 491 patients diagnosed with MF between 2012 and 2016 (mean [SD] age at diagnosis, 65.4 [11.8] years; 54.8% male, 69.2% with primary MF) were included. Risk categorization was not assigned for 30.1% of patients. Of the patients with a physician-assigned risk categorization (n?=?343), a scoring system was used in 49.9%. Compared with data-derived risk categorizations, 42.9% of physician-assigned risk categorizations were incorrect; 85.0% of incorrect physician-assigned risk categorizations were underestimations. Notably, 38.5% of patients with data-derived intermediate- or high-risk categorizations did not initiate treatment within 120 days of diagnosis. Among patients with data-derived intermediate risk, those with an underestimated physician-assigned risk categorization were significantly less likely to receive treatment within 120 days of diagnosis (51.6% with correct physician-assigned categorization vs 18.5% with underestimated risk categorization; P?=?0.0023). These results highlight the gap in risk assessment and the importance of accurate risk stratification at diagnosis.

Project description:ObjectiveThe objective of this study was to determine the associations among migraine disability assessment scores, healthcare resource utilization (HCRU; medical visits and pharmacy use) and direct medical costs among people with episodic migraine in a real-world setting.BackgroundMigraine is a public health concern associated with a substantial economic burden in the United States. However, the association between migraine disability and direct medical costs among people with migraine is unknown.MethodThis retrospective, cohort study used claims and electronic health record data from the Decision Resources Group database. Adults with migraine with or without aura, defined by International Classification of Disease Revision 9 (ICD-9) or ICD Revision 10 (ICD-10) codes, and a completed Migraine Disability Assessment Scale (MIDAS) questionnaire from January 2016 to December 2018 were included (chronic migraine codes not included). The associations of MIDAS score with the cost of HCRU for the 6 months after MIDAS assessment were explored. Results were stratified by treatment setting.ResultsAmong 7662 included patients, MIDAS scores were distributed as: 3348 (43.7%; I, little/none), 1107 (14.4%; II, mild), 1225 (16.0%; III, moderate), 893 (11.7%; IVa, severe), and 1089 (14.2%; IVb, very severe). Worsening disability was associated with higher medical costs (adjusted from a multivariable model). In the primary care setting, healthcare visit costs were $206 (95% confidence interval: $144-294) for grade I and $631 ($384-1036) for grade IVb patients; corresponding pharmacy costs were $203 (grade I; $136-301) and $719 (grade IVb; $410-1259). For specialty care (e.g., neurologist), healthcare visits cost $509 ($411-629) for grade I and $885 ($634-1236) for grade IVb patients; corresponding pharmacy costs were $494 (grade I; $378-645) and $1020 (grade IVb; $643-1620).ConclusionHigher levels of migraine-related disability (MIDAS assessed) are associated with increased HCRU costs among Americans with episodic migraine. Migraine disability assessment could be useful in the development, testing, and prescription of cost-effective treatments for people with high migraine-related disability.

Project description:IntroductionThere is a need to understand the current treatment landscape for LA HNSCC in the real-world setting.MethodsThis retrospective study assessed real-world outcomes and treatment patterns of 1,158 adult patients diagnosed with locally advanced (stage III-IVB) HNSCC initiating chemoradiotherapy (CRT) within the period January 2015 to December 2017 in a large network of US community oncology practices. Structured data were abstracted from electronic health records. Demographic, clinical and treatment characteristics were analyzed descriptively overall and stratified by index treatment (cisplatin + radiotherapy [RT], cisplatin + other chemotherapy + RT, or cetuximab + RT). Time to next treatment (TTNT) and overall survival (OS) were measured using the Kaplan-Meier method, and median duration of treatment was assessed. OS was compared across treatment cohorts using multinomial logistic regression with inverse probability treatment weighting. To identify covariates associated with OS, a multivariable adjusted Cox proportional hazard model was used.ResultsThis study examined 22,782 records, of which 2124 had stage III to stage IVB and no other cancers, and 1158 met all eligibility criteria. Among the treatment cohorts analyzed (cisplatin + RT, cisplatin + other chemotherapy + RT, or cetuximab + RT), cisplatin + RT was the most common concurrent chemotherapy (65.8%). Among 1158 patients, 838 (72.4%) did not initiate subsequent treatment and 139 (12.0%) died. The median TTNT and median OS were only reached by the cetuximab + RT cohort. Among patients with oropharynx primary tumor location, patients with human papilloma virus (HPV) positive status had the longest time on treatment and highest survival at 60 months. Covariates associated with improved survival were never/former tobacco use, HPV positive status, and overweight or obese body mass index. Covariates associated with poorer survival were age of 60+ years, primary tumor location of hypopharynx or oral cavity and Eastern Cooperative Oncology Group performance status score of 2+.ConclusionThese data describe real-world treatment patterns in locally advanced head and neck squamous cell cancer and sets the baseline to assess outcomes for future studies on the community oncology population.

Project description:IntroductionMyasthenia gravis (MG) is a rare, debilitating, chronic disorder caused by the production of pathogenic immunoglobulin G autoantibodies against the neuromuscular junction. A lack of real-world studies in rare diseases reflects a relatively limited understanding of the significant unmet needs and burden of disease for patients. We aimed to provide comprehensive real-world insights into the management and burden of MG from treating physicians in the United States (US).MethodsData were collected using the Adelphi Real World MG Disease Specific Programme™, a point-in-time survey of physicians and their patients with MG, in the US between March and July 2020. Physician-reported clinical data, including demographics, comorbidities, symptoms, disease history, treatments, and healthcare resource utilization, were collected.ResultsIn total, 456 patient record forms were completed by 78 physicians based in the US. At time of survey completion, patient mean age was 54.5 years. Mean time from symptom onset to diagnosis was 9.0 months (n = 357). Ocular symptoms were reported in 71.7% of patients. General fatigue affected 47.1% of patients and over half of those reported the severity as moderate or severe (59.5%, n = 128). Acetylcholinesterase inhibitors and/or steroids were the most frequently prescribed first-line treatment type among patients receiving treatment at time of survey completion and with moderate-to-severe symptoms (77.9%, n = 159/204). High-dose steroids (n = 14) and intravenous immunoglobulin (n = 13) were the most prescribed acute treatments among those receiving an acute treatment at time of survey completion (n = 36), with symptom exacerbations or myasthenic crises being the most common reasons for acute treatment. On average, 2.5 healthcare professionals were involved in patient management and 5.0 consultations were made per patient over the last 12 months.ConclusionsOur findings indicated that, despite treatment, there is a proportion of patients with MG in the US who had a significant need for improved disease management.
