Preventing medication prescribing errors.

Medication errors may arise in the manufacture, preparation, distribution, and administration of drugs. Physician prescribing errors are of particular importance as such errors have been associated with significant adverse patient outcomes. The pharmacist plays an important role in preventing such errors from reaching the patient. The purpose of this article is to define and illustrate the various error types and the mental attitudes that cause individuals to prescribe errant orders. Through better understanding of the cause of prescribing errors, pharmacists may be able to improve the error prevention services they provide. Based on the error types discussed and their causes, recommendations are proposed to decrease the frequency of such errors and thereby improve the quality of patient care.

Medication prescribing errors in a teaching hospital.

A study of prescribing errors committed by physicians that occurred in a tertiary-care teaching hospital is reported. From a total of 289 411 medication orders written during the 1-year study period, 905 prescribing errors were detected and averted, of which 522 (57.7%) were rated as having potential for adverse consequences. The overall detected error rate was 3.13 errors for each 1000 orders written and a rate of 1.81 significant errors per 1000 orders. The error rate (4.01 per 1000 orders) was greatest between 12 pm and 3:59 pm. First-year postgraduate residents were found to have a higher error rate (4.25 per 1000 orders) than other prescriber classes, and obstetrics/gynecology services (3.54 per 1000 orders) and surgery/anesthesia services (3.42 per 1000 orders) had greater error rates than other services. The study results demonstrate the significant risk to patients from medication prescribing errors. Educational, operational, and risk-management activities should include efforts directed at reducing the risk to patients from prescribing errors.

Lindane (Kwell)-induced aplastic anemia.

Numerous toxic exposures have been implicated in causing aplastic anemia. Thirteen cases of aplastic anemia and 5 cases of other blood dyscrasias, eg, red blood cell aplasia and thrombocytopenia, associated with lindane, have been reported in the literature. However, aplastic anemia secondary to the scabicidal product (lindane [Kwell]) has not been documented, to our knowledge. We present the case of a 21-year-old man with a diagnosis of aplastic anemia, known prolonged exposure to lindane, and documented elevated serum lindane levels. His clinical course is described as well as various defects are explored for the aplasia.
