Arkansas replaced individualized nurse assessments of home-care hours with an algorithm (RUGs, then Optum's ARIA); federal and state courts found due-process violations after cuts left some recipients with barely half their prior hours.

Context
In 2016, the Arkansas Department of Human Services introduced RUGs, an interRAI-based algorithm, to set weekly home-care hours for Medicaid beneficiaries with disabilities, replacing individualized nurse assessments.
Objectives
The stated aim was a standardised, algorithmic method for allocating home- and community-based-services hours in place of case-by-case nursing judgement.
Activities
Nearly half of beneficiaries saw their hours cut under RUGs; courts in Jacobs v. Gillespie and Ledgerwood v. Arkansas DHS found the algorithm violated due process by giving no meaningful explanation for cuts, leading DHS to retire RUGs and adopt Optum's ARIA system in 2019.
Results
Under RUGs, one widely reported recipient's hours fell from 56 to 32 a week despite no change in her condition; under ARIA, over a quarter of assessed individuals became ineligible and the overall weekly hours cap fell from 56 to 46.
Conclusions
A further suit, Elder v. Gillespie, again found due-process problems with ARIA; a 2022 settlement including nearly $500,000 in payments required DHS to give written reasons for cuts and continue benefits during appeals, though advocates report arbitrary-seeming cuts have persisted since.
Implementation

Conditions for success
meaningful, individualized written explanations for hours reductions
continuation of benefits during appeals (post-2022 settlement)
independent legal advocacy capacity to challenge algorithmic decisions
Common failure modes
algorithm gave no meaningful explanation for cuts (RUGs), found to violate due process
arbitrary-seeming cuts reported to persist even after procedural fixes
over a quarter of assessed individuals became ineligible under the successor system
