Prescription errors by emergency physicians for inpatients are associated with emergency department length of stay

Risk Factors for Electronic Prescription Errors in Pediatric Intensive Care Patients

OBJECTIVES

To assess risk factors for electronic prescription errors in a PICU.

DESIGN

A database of electronic prescriptions issued by a computerized physician order entry with clinical decision support system was analyzed to identify risk factors for prescription errors.

MEASUREMENTS AND MAIN RESULTS

Of 6,250 prescriptions, 101 were associated with errors (1.6%). The error rate was twice as high in patients older than 12 years than in patients children 6-12 and 0-6 years old (2.4% vs 1.3% and 1.2%, respectively, p < 0.05). Compared with patients without errors, patients with errors had a significantly higher score on the Pediatric Index of Mortality 2 (-3.7 vs -4.5; p = 0.05), longer PICU stay (6 vs 3.1 d; p < 0.0001), and higher number of prescriptions per patient (40.8 vs. 15.7; p < 0.0001). In addition, patients with errors were more likely to have a neurologic main admission diagnosis (p = 0.008) and less likely to have a cardiologic diagnosis (p = 0.03) than patients without errors.

CONCLUSIONS

Our findings suggest that older patient age and greater disease severity are risk factors for electronic prescription errors.

[Management of medication errors in general medical practice: Study in a pluriprofessionnal health care center]

BACKGROUND

Medication errors are the most frequent medical care adverse events in France. Their management process used in hospital remains poorly applied in primary ambulatory care.

OBJECTIVES

The main objective of our study was to assess medication error management in general ambulatory practice. The secondary objectives were the characterization of the errors and the analysis of their root causes in order to implement corrective measures.

METHODS

The study was performed in a pluriprofessionnal health care house, applying the stages and tools validated by the French high health authority, that we previously adapted to ambulatory medical cares.

RESULTS

During the 3 months study 4712 medical consultations were performed and we collected 64 medication errors. Most of affected patients were at the extreme ages of life (9,4 % before 9 years and 64 % after 70 years). Medication errors occurred at home in 39,1 % of cases, at pluriprofessionnal health care house (25,0 %) or at drugstore (17,2 %). They led to serious clinical consequences (classified as major, critical or catastrophic) in 17,2 % of cases. Drug induced adverse effects occurred in 5 patients, 3 of them needing hospitalization (1 patient recovered, 1 displayed sequelae and 1 died). In more than half of cases, the errors occurred at prescribing stage. The most frequent type of errors was the use of a wrong drug, different from that indicated for the patient (37,5 %) and poor treatment adherence (18,75 %). The systemic reported causes were a care process dysfunction (in coordination or procedure), the health care action context (patient home, not planned act, professional overwork), human factors such as patient and professional condition. The professional team adherence to the study was excellent.

CONCLUSION

Our study demonstrates, for the first time in France, that medication errors management in ambulatory general medical care can be implemented in a pluriprofessionnal health care house with two conditions: the presence of a trained team coordinator, and the use of validated adapted and simple processes and tools. This study also shows that medications errors in general practice are specific of the care process organization. We identified vulnerable points, as transferring and communication between home and care facilities or conversely, medical coordination and involvement of the patient himself in his care.
