Cost-Effectiveness of Florbetapir-PET in Alzheimer's Disease: A Spanish Societal Perspective
John Hornberger, Steven Michalopoulos, Minghan Dai, Paula Andrade, Tatiana Dilla, Michael Happich. The journal of mental health policy and economics, 2015-06
Topic: Drug trials: efficacy and safety
Adjunctive florbetapir-PET increased quality-adjusted life years (QALYs) by 0.008 years and increased costs by 36 compared to SCE alone (incremental cost-effectiveness ratio [ICER], 4,769). Use of florbetapir-PET was dominant in alternate scenarios. Sensitivity analyses indicated rates of institutionalization (by MMSE) and MMSE score upon initiation of acetylcholinesterase inhibitor (AChEI) treatment most influenced the primary outcome (ICER) in the base case scenario. Over 82% of probabilistic simulations were cost-effective using the Spanish threshold (30,000/QALY). The addition of florbetapir-PET to SCE is expected to improve the accuracy of AD diagnoses for patients experiencing cognitive impairment; it is cost-effective due to decreased healthcare costs and caregiver burden. Prospective studies of the clinical utility of florbetapir-PET are necessary to evaluate the long-term implications of adopting florbetapir-PET on clinical outcomes and costs in real-world settings. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: Florbetapir-PET is expected to improve decision-making regarding appropriate and sufficient care for cognitively impaired patients with suspected AD, while cost-effective. IMPLICATIONS FOR HEALTH POLICIES: Earlier and more accurate diagnosis of AD may help to improve patient's health status and reduce treatment costs by effectively allocating healthcare resources and maximizing the benefit of treatments and supportive services. IMPLICATIONS FOR FURTHER RESEARCH: Use of florbetapir-PET may help accurately identify patients with AD. The development of novel therapeutics for use with companion diagnostics may provide additional benefits by slowing or halting progressive cognitive decline with AD, increase QoL and prolong survival.

How this study scored 38/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 21 of the 56 points we could judge it on, which is 38 out of 100.
