THE INCIDENCE OF DRUG-RELATED PROBLEMS AS A CAUSE OF HOSPITAL ADMISSIONS IN CHILDREN

Objectives: To determine the incidence of hospital admissions for drug -related problems (DRPs) among children, and to examine cases for caus ality, preventability and clinical severity. Design: Prospective asses sment involving review of case notes and parent interview to determine if an admission was associated with a DRP. Patients and setting: All patients admitted to a large university-affiliate paediatric hospital in Melbourne, Victoria, for medical reasons (ie, not surgical, trauma or oncology patients) during 56 consecutive days from 24 June to 19 Au gust 1996 for which a DRP could be identified. Patients whose parents or guardians could not communicate adequately in English were excluded . Main outcome measures: The incidence, type, causality, preventabilit y and clinical severity of DRPs associated with admission. Results: Of 1682 eligible patients admitted to the Royal Children's Hospital duri ng the study period, 58 admissions (3.4%) were associated with DRPs. N on-compliance was implicated in 50%. Causality was ranked as ''definit e'' (34.5%), ''possible'' (56.9%) and ''doubtful'' (8.6%). Two-thirds of admissions associated with DRPs were deemed preventable. Although n o patients died from DRPs, four were admitted to the intensive care un it. Conclusions: The incidence of DRPs as a cause of hospital admissio n in this study falls within the range of incidences published for the Australian adult population (range, 2.4%-22%). In contrast to finding s among Australian adults, a high proportion of admissions for DRPs in this study were associated with non-compliance. The high percentage o f preventable admissions indicates that further study is necessary to characterise risk factors within this population and to test preventio n strategies.
