Pattern of Intensive Care Unit Admission Due to Drug Problems, KAMEL A. MOHAMED
Abstract
Introduction: Drug related problems (DRPs) are of major concern, affecting patients of both sex. They impose consid-erable economic burden on the society and the health-care systems.
Aim of the Work: The aim of this work was to identify and categorise drug-related problems in adult intensive care unit.
Patients and Methods: The study was a prospective, observational study as eighty six patients were included. They were consecutively admitted to ICU through the emergency room or transferred from the general ward due to DRPs. Parameters included in the study as length of stay in ICU, need for cardiovascular support or mechanical ventilation, dialysis, as well as APACHE II score were recorded.
Results: Drug related problems represent 3.6% of the total ICU admission. The median (range) of APACHE II score for 86 patients included in the study was 17 (10-23), and length of ICU stay was 2.4 (1.5-4.2) days. In 45 patients (52%), DRP was drug over dose (group I), while other DRP was present in the other 41 patients (48%, group II). Patients in group 1 were older (39 years versus 32 years in group II), with significant impaired renal function. The need of inotropic drugs and mechanical ventilation as well as the length of stay (LOS) in ICU was significantly higher in group I. There were no significant difference in GCS between both groups, however APACHE II score was significantly higher in group I. Only four patients (4.6%) were admitted by suicidal attempt as well as three patients (3.4%) due to trauma drug-related admissions, all were in (group I). Nineteen percent of the patients had drug related problem due to hypoglycaemic medication fol-lowed by tranquillizer (15%). Adverse drug effect followed by failure to receive medication were the most causes of drug problem in (group 2). The total mortality rate was 4.6%, all of them were eventually non preventable.
Conclusion: The critically ill patients admitted due to drug related problems represented a small proportion (3.6%) of admissions to the ICU. Hypoglycaemic medication was one of the most common causes of admission by drug related problems.
