Simulated hypothetical drug substitutions using MedUTI software in COVID-19 ICU patients resulted in a 53% decrease in high-risk patients (from 96.0% to 43.0%) based on Tisdale score assessment of cardiovascular adverse drug events.
Key Findings
Results
The vast majority of COVID-19 ICU patients were classified as high cardiovascular risk at baseline using the Tisdale score.
96.0% of patients were classified as high-risk prior to any intervention
Analysis was based on 141 medical records of COVID-19 patients admitted to an ICU reference hospital in BrasÃlia, Brazil in 2020
The Tisdale score was used as the risk assessment tool
Brazil recorded more than seven million COVID-19 cases in 2020
Results
Simulated hypothetical drug substitutions reduced the proportion of high-risk patients by 53%.
High-risk patients decreased from 96.0% to 43.0% after simulated prescription intervention
56% of patients began to show a Tisdale score of medium or low risk in the optimized prescription condition
Simulations were performed using MedUTI software
The intervention involved hypothetical drug substitutions rather than actual clinical changes
Results
The total number of medications with serious cardiovascular adverse drug events decreased following simulated prescription optimization.
Medications with serious cardiovascular ADEs decreased from 67 to 51
QT interval prolongation-associated medications decreased from 37 to 30
Torsades de Pointes-associated medications decreased from 21 to 15
Serotonin syndrome (SS)-associated medications decreased from 9 to 6
Background
COVID-19 ICU patients were subject to qualitative polypharmacy, increasing their risk of serious cardiovascular adverse drug reactions.
Most patients affected by COVID-19 were admitted to intensive care units requiring qualitative polypharmacy
Polypharmacy in the ICU setting was identified as a key driver of increased cardiovascular ADE risk
Cardiovascular ADEs assessed included QT interval prolongation, Torsades de Pointes, and serotonin syndrome
The study was conducted at a reference hospital for COVID-19 treatment in BrasÃlia, Brazil
Conclusions
Technology-assisted medication management using decision-support software was identified as a tool capable of substantially reducing cardiovascular risk in ICU settings.
MedUTI software was used to simulate hypothetical drug substitutions
The software-assisted approach demonstrated a 53% reduction in high-risk classifications
Authors concluded that 'the use of technologies to support healthcare professionals' work can be decisive for patient survival, especially in ICU overcrowding scenarios'
The COVID-19 medical emergency highlighted the need for rapid medication management in ICU patients
