The economics of inpatient on-demand treatment for haemophilia with high-responding inhibitors: a US retrospective data analysis.

Inpatient costs comprise >50% of annual healthcare costs for haemophilia patients with inhibitors but no reports exist on inpatient resource use and costs at a US national level. To quantify inpatient resource use and costs for on-demand treatment of bleeds of US haemophilia patients with inhibitors and compare costs and treatment duration between Factor VIII bypassing agents (BAs). Stays with haemophilia A from 2003-2008 were identified from inpatient billing records. Presence of inhibitors was inferred through use of BA; recombinant activated Factor VII and plasma-derived activated prothrombin complex concentrate. Duration and number of infusions of BA, length of stay, use of opioid-containing analgesics and costs were assessed and compared. Among 1322 stays mean BA treatment duration was 4.6 days with 4.9 infusions, 6.1 nights spent in hospital, and 58% administered opioid-containing analgesics. In unadjusted analyses there were significant differences in the above mentioned outcomes by BA use, reflecting underlying differences between the two patient populations. Average inpatient costs were $82,911. In adjusted analyses, African-American race, greater disease severity, hospital region outside the southern US and older age (cost model only) were significant predictors of longer BA treatment duration and higher costs. The economic burden of inpatient on-demand treatment of haemophilia with inhibitors is substantial and is associated with lengthy stays, high costs and inadequate pain relief. Availability of more effective BAs could reduce the need for re-treatment, reducing treatment costs and other medical costs, while improving health related quality of life.

Evidence-based interventions to improve patient compliance with antihypertensive and lipid-lowering medications.

The MEDLINE database was searched from 1972 to June 2002 to identify studies of interventions designed to improve compliance with antihypertensive or lipid-lowering medications. Studies were required to employ a controlled design, follow patients for >or=6 months and measure compliance by a method other than patient self-report. The literature review yielded 62 studies describing 79 interventions. Overall, 56% of interventions were reported to improve patient compliance. When only those studies meeting minimum criteria for methodological quality were considered, 22 interventions remained and 12 were recommended, because they demonstrated a significant improvement in compliance. Recommended interventions included fixed-dose combination drugs, once-daily or once-weekly dosing schedules, unit-dose packaging, educational counselling by telephone, case management by pharmacists, treatment in pharmacist- or nurse-operated disease management clinics, mailed refill reminders, self-monitoring, dose-tailoring, rewards and various combination strategies. Personalised, patient-focused programs that involved frequent contact with health professionals or a combination of interventions were the most effective at improving compliance. Less-intensive strategies, such as prescribing products that simplify the medication regimen or sending refill reminders, achieved smaller improvements in compliance but may be cost-effective due to their low cost.

Impact of mycophenolate mofetil (MMF)-related gastrointestinal complications and MMF dose alterations on transplant outcomes and healthcare costs in renal transplant recipients.

Mycophenolate mofetil (MMF), a mycophenolic acid prodrug, is a highly effective adjunct immunosuppressive agent in transplant therapy. Although MMF is generally well tolerated, optimal therapy may be limited by adverse effects, in particular gastrointestinal (GI) toxicity, which has been reported to occur in up to 45% of MMF-treated patients. MMF dose changes resulting from these adverse events may lead to sub-therapeutic dosing and impaired clinical outcomes. This retrospective study analyzed clinical records from 772 renal transplant patients from 10 US transplant centers who were initiated on MMF. The analysis revealed that 49.7% (n = 382) of patients experienced at least one GI complication within the first 6 months post-transplant, with 66.8% (n = 255) of these having multiple GI complications. Of the patients with GI complications, 39.0% experienced MMF dose adjustments or discontinuation of MMF therapy. Patients with GI complications who experienced MMF dose adjustments/discontinuation had a significantly increased incidence of acute rejections compared with patients without GI complications (30.2% vs. 19.4%; p = 0.005). Mean treatment costs were higher in patients with GI complications than in those with no GI complications, particularly in those who experienced MMF dose adjustments/discontinuation (p = 0.0001). The mean incremental cost for patients experiencing GI complications was US$3700 per patient during the 6 months post-transplant (p < 0.001), which was mainly attributable to hospitalization costs. In summary, GI complications and MMF dose adjustments/discontinuations are associated with a significant negative impact on transplant outcomes and markedly increase short-term treatment costs.
