Preventability and severity assessment in reporting adverse drug reactions

An observational study of cutaneous adverse drug reactions in a teaching hospital

“…The severity of the ADRs was determined using Hartwig Scale. According to this scale ADRs were assessed as mild (level 1, 2), moderate (level 3, 4, 5) and severe (level 6, 7) [2] and Preventability assessment was done using modified Schumock and Thornton criterion [3].…”

Adverse drug reactions experience in a teaching hospital in Jordan

“…These forms were then sent to the research team, who carried out the causality, preventability and severity assessments. Each suspected ADR was assessed for: causality using Naranjo's probability scale, severity using Hartwig's criteria, and preventability using Schumock and Thornton's criteria [12][13][14]. Naranjo's probability scale was used to evaluate the causality relationship between an ADR and a drug.…”

Patterns, predictors and preventability of adverse drug reactions in the coronary care unit of a tertiary care hospital

“…Preventability was assessed using the modified Schumock and Thornton scale [11] which classifies ADRs as definitely preventable, probably preventable and not preventable, respectively. The severity of the ADRs was assessed using the modified Hartwig and Siegel severity assessment scale [12] which classifies ADRs as mild, moderate and severe, respectively. The predictability of the ADRs (predictable or non-predictable) was also assessed.…”
