Introduction:
The objective of this study is to analyse the appropriateness and characteristics of drug dose calculation for hospitalised, morbidly obese patients.
Methods:
Retrospective, descriptive study of dose calculations for drugs prescribed to hospitalised, morbidly obese patients in a tertiary hospital in 2007. The recommendations prepared by the Pharmacy division are used as a standard.
Results:
We included 62 patients. The mean number of medications prescribed per patient was 12.1 (4-39), and an average of 2.4 (1-10) are listed in the recommendations. A total of 135 drugs were prescribed. Dose calculations for 81 of the above (60 %) coincided with recommendations and 54 (40 %) did not; there were 51 cases of underdosing and three cases of overdosing.
Discussion:
Improper dosing was detected for prescriptions in the systemic antibiotic and antithrombin drug groups, with underdosing being more common than overdosing.
