Study summary

The overall goal of this study will be to assess and monitor the adherence to and effectiveness of the new prescribing guidelines for cabergoline.

Specific objectives will be to assess: 1. The indication for use of cabergoline (Parkinson, hyperprolactinemia, other) 2. Prior treatment strategies in patients who start cabergoline treatment for Parkinson's Disease 3. The percentage of cabergoline users who are prescribed doses above 3 mg per day 4. Whether cabergoline users are monitored by echocardiography prior and during treatment. 5. The incidence and prevalence of valvular fibrosis

Study population

Cohort of patients, who are treated with cabergoline during the study period. This cohort will be divided in new users and prevalent users based on when cabergoline was started. New (incident) users will be all persons who have a first prescription for cabergoline after the date that the change in SPC was made. Prevalent users will be all cohort members who received a cabergoline prescription during the study period but who had also been using cabergoline prior to the change in SPC.

Exclusion criteria

Exclusion Criteria:

  • Patients with eligibility dates that start after July 1st 2007 (meaning that they would have less than one year of valid data before publication of the results of the EMEA review), will be excluded as well as patients whose eligibility ends before July 1st 2008 (date of SmPC changes).

PrimaryIncidence of Valvular Fibrosis

Incidence of valvular fibrosis was calculated as number of participants with documented valvulopathy during cabergoline treatment and absence of any valve damage at baseline divided by number of participants without any valve damage at baseline and at least 1 additional echocardiography examination during follow-up while on cabergoline treatment. Percentage of participants with valvular fibrosis are reported.
