In general terms, it encom passes m anic and depressive mood episodes with sub-syndrom ic states and periods of stability. Even though theoretically the treatm ents available are effective, relapses are still very frequent and disabling in the real world [2]. Therefore, the healthcare resources used, direct cost and functional burden associated with every new episode of the disorder have relevant im plications in public health. Few studies had explored these issues in our setting [3]. Objective: The main objective of this study is to describe the general burden and cost associated with manic episodes both in inpatients and outpatients in four University Hospitals in Catalonia (Spain). Method: 169 bipolar I disorder patients presenting an acute manic episode (based on DSM-IV criteria) were included. Demographic variables were collected as well as clinical variables during the last six m onths. We retrospectively assessed effectiveness (YMRS, HDRS-17), functionality (FAST) and health resource consumption, measured by means of days of hospitalization, re-hospitalizations, em ergency department and outpatient consultations. Results: There was a greater percentage of males (53.8a) compared to females (46.2a) in the sample. The mean age was 42.5 years. 14.2 were the mean years since the bipolar disorder was first diagnosed among the patients. The majority of patients (78.7a) were hospitalized at the m oment of the first assessm ent. Up to 53.3a of patients had a comorbid substance use disorder. The m ost commonly prescribed drug was lithium (43.8a), followed by valproic acid (36.1a). The vast majority of patients (98.2a) were treated with antipsychotics including aripiprazole, asenapine, olanzapine, quetiapine and risperidone, and most of them were in combination with m ood stabilizers. Regarding other mood stabilizers, they were prescribed in a far lesser extend as follows lam otrigine (7.7a), oxcarbamazepine (4.1a), topiramate (4.1a) and carbamazepine (1.8a). Among benzodiazepines, the most common prescribed were clonazepam (32a), lormetazepam (26.6a) and diazepam (8.3a). Mean days of hospitalization were 19.8 (11.6). Furthermore, 9.2a of patients were readmitted during the study for a m ean of 68.1 (61.8) days. Thirty-six em ergency room visits were recorded during follow-up. Finally, at six-month 33.3a of the previously employed were still on sick leave. The mean total cost per treatment day for outpatients was 16.58€ (67.9a of it from pharmacological treatment) while for inpatients was 43.47€ (73.5a of it from hospitalization charges). Conclusions: The results from the MANACOR study showed that the most prescribed drugs for the treatment of mania are mainly antipsychotics com bined with m ood stabilizers, lithium being the most used. The treatment was highly effective as shown by the reduction in severity scale scores. Although the functionality measured by FAST scale im proved, approximately one-third of the sam ple was still on sick leave at 6-month follow-up. The cost of treating manic episodes was almost three times higher for inpatients when com pared to outpatients. 1.
