The Differential Burden of Three Healthcare-associated Infections on Hospital Costs and Lengths-of-Stay: a Quasi-experimental Case-Control Observation
Abstract
In patients with a healthcare-associated infection (HAI), lengths-of-stay and costs increased >150% from 2019-2023, and were 2-6x greater compared to concurrent non-HAI patients with the same diagnoses. Unlike surgical HAI, no device-associated HAI occurred before hospital day 12. These findings highlight the possibly under-recognized influence of delayed discharges on device-associated HAIs.
How strong is the evidence?
Evidence Hub reads this as a case-control. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
