Change in stimulation contact configuration as expressed in fraction of patients using a certain contact point as anode or cathode.
Fraction of patients using a certain contact point as cathode or anode during the first 2 years after intervention minus fraction of patients using a certain contact point as cathode or anode during the last 2 years before intervention.

Change in frequency of outpatient clinic contacts at the Psychiatry department. Frequency of outpatient clinic contacts at the Psychiatry department during the first 2 years after intervention minus frequency of outpatient clinic contacts at the Psychiatry department during the last 2 years before intervention.

Change in fraction of hospitalized days at the Psychiatry department. Fraction of hospitalized days at the Psychiatry department during the first 2 years after intervention minus fraction of hospitalized days at the Psychiatry department during the last 2 years before intervention.

Change in frequency of outpatient clinic contacts at the Neurosurgery department.
Frequency of outpatient clinic contacts at the Neurosurgery department during the first 2 years after intervention minus frequency of outpatient clinic contacts at the Neurosurgery department during the last 2 years before intervention.

Change in fraction of hospitalized days at the Neurosurgery department. Fraction of hospitalized days at the Neurosurgery department during the first 2 years after intervention minus fraction of hospitalized days at the Neurosurgery department during the last 2 years before intervention.

Change in frequency of neurosurgical procedures related to the DBS system. Frequency of neurosurgical procedures related to the DBS system after intervention minus frequency of neurosurgical procedures related to the DBS system before intervention.
