Influence of Pramipexole Extended Release on Medication Adherence in Parkinson´s Disease

March 14, 2014 updated by: Boehringer Ingelheim

Influence of Pramipexole Extended Release on Medication Adherence in Real Life Care of Parkinson's Disease

This is an open-label, prospective post marketing surveillance study to be performed in Sweden. Only data of patients idiopathic PD should be documented, in whom the treating physician plans to initiate a pharmacotherapy with PPX ER independent of this observational study. The questionnaires (Morisky Medication Adherence Measure, patient preference scale, CGI-I, PGI-I) will be used to document routine care in a standardized way and thus ensure high validity of the observational data. As the degree medication adherence of patients is routinely evaluated by their physicians, as is patient preference and possible symptom improvement after initiation of a new therapy, the patient questionnaires will be used to standardise medical routine care and to ensure validity of observational data.

Description

Inclusion criteria:

  1. Patients suffering from idiopathic PD who before inclusion into the observation had been planned to be treated with PPX ER according to the SP, and where decision of treatment was made independently of the patients¿ inclusion into this observational study
  2. Stable dose of PPX IR for at least 4 weeks before inclusion into the observation
  3. Male or female PD patients aged at least 30
  4. Ability to reliably complete self-rating scales (Morisky Medication Adherence Measure, patient preference scale) according to the physician¿s judgement
  5. Written informed consent by the patient for study participation.

Exclusion criteria:

  1. Patients who are not able to understand the questionnaires (e.g. due to mental impairment or language problems) according to the physician¿s judgement.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patients With a Score of 4 in Morisky Scale After 8-12 Weeks of Treatment
Time Frame: 8-12 weeks
Morisky scale: 4 Yes/No Questions: Do you ever forget to take your medicine? Are you careless at times about taking your medicine? When you feel better do you sometimes stop taking your medicine? Sometimes if you feel worse when you take the medicine, do you stop taking it? Score one point for every NO: 0-1 points = low adherence, 2-3 points = moderate, 4 points = high adherence Confidence interval computed using the Clopper-Pearson (exact) method.
8-12 weeks
Level of Adherence
Time Frame: 8-12 weeks
Points on Morisky scale
8-12 weeks

Secondary Outcome Measures

Patients Global Impressions (PGI)
Time Frame: 8-12 weeks
Assessed by asking the patient at the final visit which alternative described how they had felt during the last 7 days as compared to how they felt at the baseline observation.
