Development and implementation of an electronic Clinical Dementia Rating and Financial Capacity Instrument-Short Form.

Introduction: To address the need for remote assessments of cognitive decline and dementia, we developed and administered electronic versions of the Clinical Dementia Rating (CDR®) and the Financial Capacity Instrument-Short Form (FCI-SF) (F-CAP®), called the eCDR and eFCI, respectively. Methods: The CDR and FCI-SF were adapted for remote, unsupervised, online use based on item response analysis of the standard instruments. Participants completed the eCDR and eFCI first in clinic, and then at home within 2 weeks. Results: Of the 243 enrolled participants, 179 (73%) cognitively unimpaired (CU), 50 (21%) with mild cognitive impairment (MCI) or dementia, and 14 (6%) with an unknown diagnosis, 84% and 85% of them successfully completed the eCDR and eFCI, respectively, at home. Discussion: These results show initial feasibility in developing and administering online instruments to remotely assess and monitor cognitive decline along the CU to MCI/very mild dementia continuum. Validation is an important next step.

aPCC vs. rFVIIa for the treatment of bleeding in patients with acquired haemophilia - a cost-effectiveness model.

BACKGROUND: Acquired haemophilia A (AHA) is an autoimmune bleeding disorder with significant morbidity and mortality. Bleeding AHA patients with high titre inhibitors can be treated with either activated prothrombin complex concentrate (aPCC) or recombinant activated factor VII (rFVIIa). Given that both replacement therapies have inherent benefits and limitations, a cost-effectiveness analysis (CEA) was performed in this population to compare rFVIIa with aPCC. METHODS: In high-titered AHA patients with bleeding treated with either aPCC or rFVIIa, during a 5-day study period, a Markov model was developed such that these patients were transitioned into four different health states: (1) continuous bleeding, (2) thrombosis, (3) stop bleeding and (4) death, with states (2), (3) and (4) modelled as absorbing states. Model parameters, including probabilities, health utility index and costs, were gathered from the medical literature, except for the costs of aPCC and rFVIIa, which were obtained from our institutional data. RESULTS: During the 5-day period, the total treatment cost of rFVIIa was substantially more than the cost of aPCC ($13 635 vs. $1741). The average quality-adjusted life days (QALDs) gained for rFVIIa were slightly lower compared to aPCC (4·08 vs. 4·09). Overall, aPCC prevailed over rFVIIa. Sensitivity analysis confirmed the robustness of the model across tested ranges of all input variables. CONCLUSION: In high-titered AHA patients with bleeding, aPCC is a cost-effective treatment option when compared to rFVIIa. Thus, aPCC may be considered in these patients, if available, and provided there is no clinical contraindication.
