Objective: We conducted the first pilot Italian study to assess the preventability of adverse drug reactions involving psychotropic drugs reported through spontaneous reporting system from 01/07/2012 to 31/12/2014 in Campania Region. Methods: Preventability was assessed, case-by-case, using an adapted version of the P-method. The evaluation was performed only for those reports that had, as suspected drug, antipsychotics, mood stabilizers, antidepressants, anxiolytic and/or sedative-hypnotic. Results: Eighty-one cases (19.2%) out of 421 reported during the study period were preventable. In seventy-seven (95.1%) out of 81 preventable cases, the underlying mechanism of the adverse drug reactions was dose-related, in four (4.9%) preventable cases the underlying mechanism of the adverse drug reactions was respectively susceptibility- (1; 1.2%), unknown- (1; 1.2%) and time-related (2; 2.5%). In the 81 preventable cases, 97 critical criteria were detected of which 29/97 (29.9%) related to healthcare professionals’ practices, 0/97 (0.0%) to drug quality and 68/97 (70.1%) to patient behaviour. Conclusions: We proved that it was possible to apply and adapt the P-Method to assess the preventability of the adverse drug reactions involving psychotropic drugs, analysing individual case safety report sent through Campania Region spontaneous reporting system. Information acquired will be used to organize educational activities for both physicians and patients to promote a more appropriate drug use.

Abstract

Objective: We conducted the first pilot Italian study to assess the preventability of adverse drug reactions involving psychotropic drugs reported through spontaneous reporting system from 01/07/2012 to 31/12/2014 in Campania Region. Methods: Preventability was assessed, case-by-case, using an adapted version of the P-method. The evaluation was performed only for those reports that had, as suspected drug, antipsychotics, mood stabilizers, antidepressants, anxiolytic and/or sedative-hypnotic. Results: Eighty-one cases (19.2%) out of 421 reported during the study period were preventable. In seventy-seven (95.1%) out of 81 preventable cases, the underlying mechanism of the adverse drug reactions was dose-related, in four (4.9%) preventable cases the underlying mechanism of the adverse drug reactions was respectively susceptibility- (1; 1.2%), unknown- (1; 1.2%) and time-related (2; 2.5%). In the 81 preventable cases, 97 critical criteria were detected of which 29/97 (29.9%) related to healthcare professionals’ practices, 0/97 (0.0%) to drug quality and 68/97 (70.1%) to patient behaviour. Conclusions: We proved that it was possible to apply and adapt the P-Method to assess the preventability of the adverse drug reactions involving psychotropic drugs, analysing individual case safety report sent through Campania Region spontaneous reporting system. Information acquired will be used to organize educational activities for both physicians and patients to promote a more appropriate drug use.
