Aim: To evaluate the value of research in the case-mix database to identify cases of drug-related anaphylactic or anaphylactoid shock.
Methods: Hospital stays of patients discharged from the University Hospital of Saint-Étienne between July 1st 2009 and June 30th 2012. Five codes from the international classification of diseases were selected: T88.6, T88.2, J39.3, T80.5 and T78.2.
Results: Among 89 cases identified by the programme for medicalization of information system (programme de médicalisation des systèmes d'information, PMSI), 40 were selected (45%). Of these, 16 cases were spontaneously reported by physicians. The unspecific code "anaphylactic shock unspecified (T78.2)" was coded for 57.5% of cases.
Conclusion: The study confirms the interest of the PMSI as a tool for health monitoring, in addition to spontaneous reporting. Nevertheless, coding with insufficient precision about the causal role of the drug, requires a return to the medical record and so an important time consuming process.
