[Retrocession, a profitable but risky activity]

The retrocession (out-patient dispensing of hospital-reserved drugs)is a pharmaceutical critical activity requiring a care security with a territorial approach. In this drug supply chain, the pharmacist is the last step before the drug administration and the economic profitability is questionable. In this context, a risk mapping and an economic evaluation seem necessary.

Methods: The risk analysis was conducted with the adverse events collected. The economic study was realised with the point of view of the hospital and with the microcosting method.

Results: Six never events were observed with the risk analysis. The economic study showed that the retrocession was profitable in usual situations with a net margin from 7 to 14€. But, when an exceptional situation occurred as a troubleshooting or the creation of a public deal, the added costs became so important (76 and 85€) that the retrocession was an unbeneficial activity.

Conclusion: The retrocession is an activity with a health, legal and economic high risk. In order to improve the healthcare quality and safety, the retrocession must be considered as a coordinated process. It means that the different health professionals must communicate with each other and that the connection between the ambulatory and the hospital care must be efficient.
