What is the PICOSI framework?

When conducting evidence synthesis, many individuals use the PICO framework. PICO stands for population; intervention; comparator(s); and outcome. This helps to describe the research question that the evidence synthesis aims to answer. However, recently Remiro‐Azócar (2024) proposed PICOSI framework. PICOSI stands for: Population Intervention Comparator(s) Outcomes Summary effect measure; Intercurrent events In fact, Canada’s Drug…

GCEA Value Flower: Summary and A Path Forward

Meng Li (2024) has a nice summary of the generalized cost effectiveness analysis (GCEA) user guide paper (see Shafrin et al. 2024) that was published last month. The GCEA methodology encompasses 15 ‘petals’ across four domains. The uncertainty domain captures how risk aversion and uncertainty in treatment outcomes impact value, including aspects such as outcome…

What is ‘Bayesian Hierarchical Modelling’ and how can it be used to evaluate oncology treatments studied in basket trials?

Should payers cover a new oncology treatment targeting specific biomarkers across multiple tumor types? One the one hand, one could require a separate trial for each tumor type. While this would be convincing evidence, it also is very expensive to conduct clinical trials for every tumor type, particularly if treatment efficacy is homogenous across tumor…

HTA and cell and gene therapy

A paper by Drummond et al. (2023) examines how health technology assessment bodies deal with the challenge of value assessment for cell and gene therapies (also known as Advanced Therapy Medicinal Products (ATMPs) in Europe). To do this the authors: …undertook i) a targeted review of the literature on the clinical and economic evidence needs…

The Carer QALY Trap

The term “Carer QALY” was coined in a paper by Mott et al. (2023) and is identified as the case where “it is possible for an effective treatment that provides survival gains (with relatively little or no QOL gain) to appear less effective than the comparators when carer QOL is considered.” While the term “Carer…

Recommendations for incorporating equity into HTA evaluation

Many health policy experts–including myself–have noted that treatments that help reduce health disparities may be especially valuable whereas those that exacerbate inequalities may be somewhat less valuable than predicted by standard cost-effectiveness analysis. A key question is, health disparities over what dimension(s)? Is it race? Income? Education? O’Nell et al. (2013) developed the PROGRESS framework.…

IVI’s Research Framework to Understand the Full Range of Economic Impacts on Patients and Caregivers

The Innovation and Value Initiative (IVI) and AcademyHealth have developed a consensus document titled “A Research Framework to Understand the Full Range of Economic Impacts on Patients and Caregivers” Direct Medical Costs: Patient or caregiver costs paid to a healthcare provider or healthcare system. Non-Clinical Healthcare Costs: Costs that are a direct result of seeking…
