IMPORTANCE Although clinical trials demonstrate the superior effectiveness of medication for opioid use disorder (MOUD) compared with nonpharmacologic treatment, national data on the comparative effectiveness of real-world treatment pathways are lacking.OBJECTIVE To examine associations between opioid use disorder (OUD) treatment pathways and overdose and opioid-related acute care use as proxies for OUD recurrence. DESIGN, SETTING, AND PARTICIPANTS This retrospective comparative effectiveness researchstudy assessed deidentified claims from the OptumLabs Data Warehouse from individuals aged 16 years or older with OUD and commercial or Medicare Advantage coverage. Opioid use disorder was identified based on 1 or more inpatient or 2 or more outpatient claims for OUD diagnosis codes within 3 months of each other; 1 or more claims for OUD plus diagnosis codes for opioid-related overdose, injection-related infection, or inpatient detoxification or residential services; or MOUD claims EXPOSURES One of 6 mutually exclusive treatment pathways, including (1) no treatment, (2) inpatient detoxification or residential services, (3) intensive behavioral health, (4) buprenorphine or methadone, (5) naltrexone, and (6) nonintensive behavioral health. MAIN OUTCOMES AND MEASURES Opioid-related overdose or serious acute care use during 3 and 12 months after initial treatment. RESULTS A total of 40 885 individuals with OUD (mean [SD] age, 47.73 [17.25] years; 22 172 [54.2%] male; 30 332 [74.2%] white) were identified. For OUD treatment, 24 258 (59.3%) received nonintensive behavioral health, 6455 (15.8%) received inpatient detoxification or residential services, 5123 (12.5%) received MOUD treatment with buprenorphine or methadone, 1970 (4.8%) received intensive behavioral health, and 963 (2.4%) received MOUD treatment with naltrexone.During 3-month follow-up, 707 participants (1.7%) experienced an overdose, and 773 (1.9%) had serious opioid-related acute care use. Only treatment with buprenorphine or methadone was associated with a reduced risk of overdose during 3-month (adjusted hazard ratio [AHR], 0.24; 95% CI, 0.14-0.41) and 12-month (AHR, 0.41; 95% CI, 0.31-0.55) follow-up. Treatment with buprenorphine or methadone was also associated with reduction in serious opioid-related acute care use during 3-month (AHR, 0.68; 95% CI, 0.47-0.99) and 12-month (AHR, 0.74; 95% CI, 0.58-0.95) follow-up. (continued) Key Points Question What is the real-world effectiveness of different treatment pathways for opioid use disorder? Findings In this comparative effectiveness research study of 40 885 adults with opioid use disorder that compared 6 different treatment pathways, only treatment with buprenorphine or methadone was associated with reduced risk of overdose and serious opioid-related acute care use compared with no treatment during 3 and 12 months of follow-up. Meaning Methadone and buprenorphine were associated with reduced overdose and opioid-related morbidity compared with opioid antagonist therapy, inpatient treatment, or intensive outp...

BACKGROUND: For first-line therapy options for advanced renal cell carcinoma (RCC), clinical trials have demonstrated similar efficacy for pazopanib and sunitinib as well as differing side-effect profiles, which may affect patient persistence in self-administration of these oral medications. However, the treatment patterns of each drug in real-world clinical practice, as opposed to the controlled environment of a trial, have not been directly compared.

BackgroundHepatitis C virus (HCV) is a risk factor for chronic kidney disease (CKD) and end-stage renal disease (ESRD). Direct-acting antiviral agents (DAAs) have improved HCV management in CKD patients, however real-world clinical practice data are limited.ObjectiveThis study examined the prevalence of CKD among HCV patients receiving oral DAAs in a real-world setting. Comorbidities, early discontinuation rates, and healthcare costs were compared between patients with and without CKD.MethodsPatients with HCV who were treated with oral DAAs between November 2013 and June 2015, and who were enrolled in a US health plan, were identified. Early discontinuation was calculated based on observed versus expected treatment duration, and expected treatment duration was based on genotype, initial treatment regimen, baseline cirrhosis, and prior treatments. Healthcare costs were calculated during the baseline, treatment, and post-treatment periods.ResultsThis study included 3438 patients receiving oral DAAs, of whom 6.9% had a CKD diagnosis. CKD patients were more often male (70.8 vs. 62.9%, p = 0.02) and older (mean age 62.0 vs. 58.8 years, p < 0.001) than non-CKD patients, and had a higher prevalence of most comorbidities. Among early discontinuers, CKD patients were more likely to experience anemia (19.4 vs. 7.7%, p = 0.028).ConclusionsFew patients with CKD receive DAA treatment for HCV infections. HCV patients with CKD had significantly more comorbidities and higher baseline healthcare costs than patients without CKD. Compared with non-CKD patients, CKD patients were equally likely to discontinue DAA treatment early but had higher rates of anemia. This study highlights the need for more renal-friendly HCV therapies.

Patients who initiated DAPA or SITA had similar all-cause and diabetes-related healthcare costs over 1 year of follow-up. In the subgroup of patients treated with OAD monotherapy at baseline (84% metformin monotherapy), those who initiated DAPA as add-on therapy had lower costs than patients who added SITA.

HZ incidence was high, despite AP use. Mean annual healthcare costs were higher for patients with HZ, but the difference was not statistically significant. An effective vaccine against HZ could be useful in decreasing both incidence of and cost for HZ in this population.

Background:Randomized clinical trials have shown long-acting mono bronchodilator therapy to be efficacious in improving lung function and dyspnea, while reducing exacerbations; however, less is known regarding the effectiveness in routine clinical practice. This study examined treatment patterns, rescue medication use, healthcare resource utilization and costs, and exacerbations in patients with chronic obstructive pulmonary disease (COPD) who initiated long-acting mono bronchodilator therapy in real-world settings.Methods:This retrospective study used US claims data from adult patients with COPD initiating long-acting mono bronchodilator therapy between 1 January 2008 and 31 January 2015. Patients were required to have continuous health plan enrollment 12 months prior to (baseline period) and 12 months following therapy initiation (follow-up period). Outcomes, including treatment patterns, rescue medication use, exacerbations, and healthcare utilization and costs, were measured until the earliest of treatment augmentation or discontinuation, death, health plan disenrollment, or the end of the study period. Results were analyzed descriptively for all measures. Baseline and follow-up measures of all-cause and COPD-related healthcare costs and exacerbations [per patient per month (PPPM)] were compared using paired t tests.Results:Among 27,394 patients with a mean follow up of 6.3 months, 18.2% augmented, 74.2% discontinued, and 7.6% continued long-acting mono bronchodilator therapy. Rescue medication use was prevalent during the follow-up period, with an average of 1.0 short-acting β agonist (SABA) fills/month and 0.8 short-acting muscarinic antagonist (SAMA) fills/month, among patients with at least one fill for the medication of interest. PPPM mean number of exacerbations was more than triple (0.17 versus 0.05, p < 0.001) and PPPM exacerbation-related costs were more than double over the follow-up period compared with baseline ($1070 versus $485). COPD-related costs accounted for 50% of all-cause costs during the follow-up period and were significantly higher compared with baseline ($1206 versus $592, p < 0.001).Conclusions:Patients initiating long-acting mono bronchodilator therapy had high rates of medication discontinuation or augmentation. Patients used more rescue medications and experienced significantly more COPD exacerbations with higher healthcare costs compared with baseline. Further research is warranted to determine whether more aggressive initial therapy would result in symptom improvement.

IntroductionLedipasvir/sofosbuvir (LDV/SOF) for hepatitis C virus (HCV) treatment provides an oral interferon-free treatment regimen with high rates of sustained virologic response (SVR). This study assessed treatment discontinuation, factors associated with treatment completion, and real-world effectiveness.MethodsPatients with HCV treated with LDV/SOF between October 2014 and June 2015 and enrolled in a large US health plan were identified. Expected treatment duration was calculated based on IDSA/AASLD treatment guidelines and US labels using data for genotype, initial treatment regimen, baseline cirrhosis, and prior treatments. Logistic regression was used to identify factors associated with treatment completion, controlling for patient characteristics.ResultsThe study included 1483 LDV/SOF patients. Mean age was 59.7 years, most were male (63.9%), had commercial insurance (51.9%), and were treatment-naïve (85.6%). Cirrhosis or end stage liver disease was present in 46.1%. Among patients with an expected 8-week treatment regimen, 49.4% were treated for longer. Most patients (99.8%) with expected 12-week treatment durations were adherent to the expected treatment duration. Treatment-experienced patients [odds ratio (OR) 0.124, p < 0.001] and those on Medicare (OR 0.382, p = 0.039) had lower odds of completing the expected treatment regimen, while males were more likely to complete treatment than females (OR 3.235, p = 0.003). SVR12 in patients treated with LDV/SOF was 89.4% (n = 76/85).ConclusionHalf of patients eligible for an 8-week treatment regimen with LDV/SOF were treated longer, while most patients with a 12-week regimen were adherent to the expected treatment duration. Prior HCV treatment, female gender, and Medicare Advantage insurance were associated with lower odds of treatment completion. Overall SVR12 was 89.4%.FundingMerck & Co.
