BackgroundThere is a scarce number of studies on the cost of agitation and containment interventions and their results are still inconclusive. We aimed to calculate the economic consequences of agitation events in an in-patient psychiatric facility providing care for an urban catchment area.MethodsA mixed approach combining secondary analysis of clinical databases, surveys and expert knowledge was used to model the 2013 direct costs of agitation and containment events for adult inpatients with mental disorders in an area of 640,572 adult inhabitants in South Barcelona (Spain). To calculate costs, a seven-step methodology with novel definition of agitation was used along with a staff survey, a database of containment events, and data on aggressive incidents. A micro-costing analysis of specific containment interventions was used to estimate both prevalence and direct costs from the healthcare provider perspective, by means of a mixed approach with a probabilistic model evaluated on real data. Due to the complex interaction of the multivariate covariances, a sensitivity analysis was conducted to have empirical bounds of variability.ResultsDuring 2013, 918 patients were admitted to the Acute Inpatient Unit. Of these, 52.8% were men, with a mean age of 44.6 years (SD = 15.5), 74.4% were compulsory admissions, 40.1% were diagnosed with schizophrenia or non-affective psychosis, with a mean length of stay of 24.6 days (SD = 16.9). The annual estimate of total agitation events was 508. The cost of containment interventions ranges from 282€ at the lowest level of agitation to 822€ when verbal containment plus seclusion and restraint have to be used. The annual total cost of agitation was 280,535€, representing 6.87% of the total costs of acute hospitalisation in the local area.ConclusionsAgitation events are frequent and costly. Strategies to reduce their number and severity should be implemented to reduce costs to the Health System and alleviate patient suffering.Electronic supplementary materialThe online version of this article (doi:10.1186/s12888-017-1373-4) contains supplementary material, which is available to authorized users.

BackgroundAgitation is a common manifestation of bipolar disorder and schizophrenia which includes symptoms ranging from inner tension and unease to violence and aggression. Much of the existing literature has focused on agitation in the acute setting, with the patient experience poorly defined. Thus, the aim of this study was to characterize agitation and its management from a patient perspective, with the focus on those who reside in the community.MethodsSurveys were completed across Germany, Spain and the UK by 583 community dwelling patients with schizophrenia or bipolar disorder who experienced episodes of agitation. Patients were recruited via either their physician or through patient support groups. The survey captured information on demographics, disease characteristics, frequency of agitation episodes and different pre-defined severity levels ranging from mild to severe, symptoms experienced during an episode, awareness of agitation and coping strategies employed by the patient. Statistics were descriptive in nature.ResultsThe most commonly reported symptoms during an episode of agitation were feeling uneasy (n = 373, 64%), restless (n = 368, 63%) or nervous (n = 368, 63%). Patients experienced an average of 22.4 (SD 57.2) mild, 15.4 (SD 61.2) moderate, 6.8 (SD 63.3) moderate-intense and 2.9 (SD 24.4) severe episodes within the last 12 months; on average 2.7 (SD 6.8) required hospital attendance. Half of patients (n = 313) had attended hospital due to agitation. In total, 71% of patients (n = 412) were aware they were becoming agitated either always or sometimes and 61% of patients (n = 347) were aware of agitation triggers either always or sometimes. The majority of patients reported being able to sometimes control their agitation (56%, n = 329) but 16% (n = 94) stated that there is typically nothing they can do. To cope with episodes 55% (n = 125) of schizophrenia patients and 66% (n = 234) of bipolar disorder patients reported taking prescribed medication.ConclusionCommunity based patients with schizophrenia and bipolar disorder reported frequently experiencing agitation episodes which they defined most commonly as feeling uneasy, restless or nervous. A range of coping strategies were reported but they were not always successful, highlighting an area of unmet need in this population.Electronic supplementary materialThe online version of this article (10.1186/s12888-018-1673-3) contains supplementary material, which is available to authorized users.
