Risk assessment for cardiovascular adverse drug events in the ICU: Case study on COVID-19 patients.

TL;DR

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

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 Brasília, Brazil in 2020
  • The Tisdale score was used as the risk assessment tool
  • Brazil recorded more than seven million COVID-19 cases in 2020

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

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

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 Brasília, Brazil

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
