Promoting equity with a multi-principle framework to allocate scarce ICU resources

Sequential organ failure assessment, ventilator rationing and evolving triage guidance: new evidence underlines the need to recognise and revise, unjust allocation frameworks

We respond to recent comments on our proposal to improve justice in ventilator triage, in which we used as an example New Jersey's (NJ) publicly available and legally binding Directive Number 2020-03. We agree with Bernard Lo and Doug White that equity implications of triage frameworks should be continually reassessed, which is why we offered six concrete options for improvement, and called for monitoring the consequences of adopted triage models. We disagree with their assessment that we mis-characterised their Model Guidance, as included in the NJ Directive, in ways that undermine our conclusions. They suggest we erroneously described their model as a two-criterion allocation framework; that recognising other operant criterion reveals it 'likely mitigate[s] rather than exacerbate[s] racial disparities during triage', and allege that concerns about inequitable outcomes are 'without evidence'. We highlight two major studies robustly demonstrating why concerns about disparate outcomes are justified. We also show that White and Lo seek to retrospectively-and counterfactually-correct the version of the Model Guideline included in the NJ Directive. However, as our facsimile reproductions show, neither the alleged four-criteria form, nor other key changes, such as dropping the Sequential Organ Failure Assessment score, are found in the Directive. These points matter because (1) our conclusions hence stand, (2) because the public version of the Model Guidance had not been updated to reduce the risk of inequitable outcomes until June 2021 and (3) NJ's Directive still does not reflect these revisions, and, hence, represents a less equitable version, as acknowledged by its authors. We comment on broader policy implications and call for ways of ensuring accurate, transparent and timely updates for users of high-stakes guidelines.

Structural Inequities, Fair Opportunity, and the Allocation of Scarce ICU Resources

The September-October 2021 issue of the Hastings Center Report highlights the important topic of allocating scarce critical care resources during the Covid-19 pandemic. The article by Alex Rajczi and colleagues urges that policy-makers use public reasoning, not private reasoning, when developing triage policies. We completely agree. We show how the allocation framework we developed as private scholars, the "Pittsburgh framework," has been supported by public reasoning. The article by MaryKatherine Gaurke and colleagues criticizes rationing based on maximizing life-years saved and mistakenly claims that our framework recommended this approach. We explain that our framework never contained such a criterion but instead included a more limited consideration of near-term prognosis. In December 2020, in response to emerging data and important criticisms, we modified our framework to further strengthen equity. We are committed to improving allocation guidelines during crisis standards of care through reflective discussions and debates.
