OBJECTIVE:To characterize drug prescriptions in a university hospital adult intensive care unit. METHODS: Single-center, observational, descriptive, cross-sectional study conducted at an adult general intensive care unit. The study population included all of the unit's inpatients from January to March 2011. The following characteristics for all prescriptions recorded during this period were examined: drug name (generic, brand name or abbreviation), dosage strength, pharmaceutical form, dose, route of administration, patient name, patient registration in the institution, clinic and hospital bed as well as the name, board license number, signature of the prescriber and date of the prescription. It was quantified the percentage of prescribed drugs included in the National List of Essential Drugs, the World Health Organization Model List of Essential Medicines and the University Hospital Center Pharmacotherapy Guide. The prescribed drugs were classified based on the Anatomical Therapeutic Chemical classification system (levels 1 and 2). RESULTS: Eight hundred forty-four prescriptions were reviewed from 72 patients (mean age: 59.04 ± 21.80), 54.92% of whom were female. The mean number of prescriptions per patient was 11.72 ± 11.68. The total number of drugs prescribed was 12,052 and 9,571 (79.41%) of the drugs were prescribed using the generic name. The most frequent absent information in the drug description was the pharmaceutical form of the drug (8,829/73.26%). The dosage strength was indicated in 7,231 (60%) of the prescriptions, and the prescriber and patient information were indicated in over 96% of the prescriptions. The prescribed drugs were classified in 13 therapeutic groups and 55 subgroups. Systemic antibacterials represented one of the most frequently prescribed subgroups. CONCLUSION: Most of the reviewed information was present in the prescriptions. However, the dosage strength and pharmaceutical form were absent in many prescriptions. The characterization of prescriptions at different hospital units is essential for the development of strategies that reduce drug utilization problems.
