Costs and Healthcare Resource Utilization Associated with Idarucizumab or Andexanet Alfa Oral Anticoagulant Reversal in Patients Hospitalized with Life-Threatening Bleeds.

Purpose: To assess costs and healthcare resource utilization (HCRU) associated with the use of idarucizumab for the reversal of dabigatran and andexanet alfa for the reversal of direct oral Factor Xa inhibitors. Methods: This retrospective study utilizing Premier Healthcare Database (PHD) included patients aged ≥18 years on direct oral anticoagulants (DOACs) who experienced life-threatening bleeds, discharged from the hospital during 5/1/2018-6/30/2019, and received idarucizumab or andexanet alfa. Inverse of treatment probability weighting (IPTW) method was used to balance patient and clinical characteristics between treatment cohorts. Results: Idarucizumab patients were older than andexanet alfa patients (median age 81 vs 77 years; p < 0.001), and less likely to experience intracranial hemorrhage (ICH) (37.1%vs 73.8%; p = 0.001). After IPTW adjustment, idarucizumab patients incurred lower mean total hospital costs ($30,413 ± $33,028 vs $44,477 ± $30,036; p < 0.001),and mean intensive care unit (ICU) cost ($25,114 ± $30,433 vs $43,484 ± $29,335; p < 0.001). Conclusions: Anticoagulant reversal therapy with idarucizumab was associated with significantly lower adjusted mean total hospital and ICU costs compared with andexanet alfa. However, a higher prevalence of ICH bleeds was noted in the andexanet alfa group. Trial Registration: Not applicable.

Healthcare Resource Utilization for Oral Anticoagulant Reversal Therapies in Non-Valvular Atrial Fibrillation/Venous Thromboembolism Patients.

BACKGROUND: The objective of the study was to describe the healthcare resource utilization (HCRU) and associated costs with hospitalized patients receiving specific versus non-specific oral anticoagulation reversal therapy for life-threatening bleeds and emergency surgeries or urgent procedures. METHODS: This retrospective observational study using the Premier Healthcare Database included adult patients aged ≥ 18 years treated with idarucizumab (IDA) or 3- or 4-factor prothrombin complex concentrates (PCC) to reverse the effects of dabigatran or warfarin, respectively, between October 2015 and February 2018. RESULTS: Median ages for IDA (n = 1,232) and PCC (n = 4,939) patients were 78 and 74 years (P < 0.001), respectively. IDA patients had lower bleeding and stroke risk assessment scores (HAS-BLED; P < 0.001 and CHA2DS2-VASc; P = 0.014) and lower prevalence of comorbidities compared with PCC patients. Median hospital length of stay was 6 and 7 days for patients who received IDA or PCC (P < 0.001), respectively. The percentage of patients with an intensive care unit (ICU) admission was lower for IDA patients compared with PCC patients (61.3% vs. 68.7%; P < 0.001). Median total costs per hospitalization were $19,357 for IDA patients and $26,920 for PCC patients (P < 0.001). Median costs per hospitalization for IDA and PCC treatment were $3,277 and $4,424, respectively. When HCRU and costs were examined by cause of reversal and type of bleed, similar trends in hospitalized costs emerged for IDA compared with PCC treatment. CONCLUSIONS: This analysis revealed lower HCRU and total hospital costs in patients administered IDA compared with PCC for reversal of oral anticoagulation, though differences in population characteristics and bleeding events were observed that may have contributed to these findings.

The safety and efficacy of methylphenidate and dexmethylphenidate in adults with attention deficit/hyperactivity disorder.

OBJECTIVE: To review the literature on the safety and efficacy of methylphenidate, OROS-methylphenidate, methylphenidate ER, and dexmethylphenidate in adults with Attention-Deficit/Hyperactivity Disorder (ADHD). To analyze the effects of different doses of methylphenidate, it's various formulations, and methylphenidate on efficacy and safety in this population. DATA SOURCES: Literature retrieval was performed through Pubmed/MEDLINE (Up to May 2010) using the terms methylphenidate, dexmethylphenidate, and attention-deficit hyperactivity disorder. In addition, reference citations from publications identified were reviewed. STUDY SELECTION AND DATA EXTRACTION: Double-blinded, placebo-controlled clinical trials, as well as crossover and open-label trials found using the search criteria listed above were included for review. Case reports were not included in this review. DATA SYNTHESIS: Attention-deficit/hyperactivity disorder (ADHD) is a psychiatric condition that is commonly seen in children and adolescents, that persists into adulthood for about 50% of patients. Methylphenidate and dexmethylphenidate are often prescribed to treat the symptoms associated with ADHD. The literature validating the safety and efficacy of methylphenidate and dexmethylphenidate in children and adolescents with ADHD is substantial. However, the literature specifically addressing the safety and efficacy of these medications in the adult population is less extensive and prescribing is often anecdotal based on child and adolescent data. Understanding the literature regarding methylphenidate and dexmethylphenidate and its effects in adults can enhance evidence-based medicine (EBM) and improve treatment outcomes. CONCLUSION: Methylphenidate and dexmethylphenidate are safe and effective medications to treat the symptoms of ADHD in adults. Based on the literature, increased doses are associated with better treatment response with moderate safety concerns. The different dosage forms available enable individualization of treatment.
