[The use of services, the effect of compensation and the costs of a panic disorder].
BACKGROUND
The use of general health care services by psychiatric patients has decreased drastically following correct diagnosis. This phenomenon, called offset effect, allows the use of inefficient health care services to be evaluated and contributes to the estimation of the relative impact of the disorder in addition to the estimation of the benefits of the training campaigns and/or the implementation of services. The aim of this study was to evaluate the offset effect and the costs of the panic disorder (PD) in a natural environment.


METHODS
The clinical data and the use of health care services over 12 months prior to diagnosis and 12 months following diagnosis were collected. Clinical evaluation of 61 patients with PD included a standard interview (SCID-UP), scales of general functioning, improvement, severity of the symptoms and the level of disability. The number of work days missed was also reported.


RESULTS
The sociodemographic features, clinical evolution and the rate of response to treatment were comparable to those referred in other studies performed in a natural medium. The direct costs of treatment of AP were 1,795,000 pesetas (1,547,000-1,889,000) higher during the year following the first psychiatric consultation, mainly due to the costs of the visits to the psychiatrist and the medication. On the contrary, the indirect costs were 5,435,000 pesetas less during this period.


CONCLUSIONS
In this study on the treatment of patients with the panic disorder a strong offset effect (94%) was found being much greater than that described for general psychiatric disorders. Adequate psychiatric treatment induces in the next 12 months an increase in the cost due psychiatric consultation and medication, however reduces the total costs when absenteeism is taken into account.
