Despite proven benefits in reducing morbidity and mortality, many patients become nonadherent to statin therapy within the first year of starting. Due to their accessibility and frequent patient contact, pharmacists are well-positioned to improve medication adherence.

The purpose of this study is to determine whether a simple intervention by community pharmacists can improve statin adherence in new statin users.

Condition Intervention
Statin Therapy Adherence Behavioral: CPATCH intervention to support statin adherence

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Health Services Research

Further study details as provided by University of Saskatchewan:

Primary Outcome Measures:
  • Mean statin adherence among all eligible new users of statin medications with at least 6 months of follow-up from index prescription [ Time Frame: 6 months ]
    All statin dispensations are captured by the prescription drug plan database. Mean adherence will be measured using the proportion of days covered (sum of days supply for statin prescriptions during study period divided by the number of days of observation). PDC will be adjusted for any days subject was hospitalized during study period.,

Secondary Outcome Measures:
  • Proportion of new statin users with adherence greater than or equal to 80% [ Time Frame: 6 months ]
  • Persistence with statin use among patients with a minimum of 12 months of follow-up [ Time Frame: 6 months ]

Estimated Enrollment: 2250
Study Start Date: March 2010
Estimated Study Completion Date: January 2012
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pharmacy Intervention Arm
All patients receiving statins from pharmacies allocated to the pharmacist intervention arm of the study
Behavioral: CPATCH intervention to support statin adherence
Routine identification of new statin users (first year of therapy), consistent assessment of barriers to adherence at every dispensation for these patients, reassurance about efficacy and safety, and proactive response to identified adherence barriers.
No Intervention: Usual Care
Pharmacies not allocated to the intervention arm will serve as the control. They received no training on the CPATCH intervention and provide usual care to patients at their pharmacy.


Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Pharmacies must fill at least 85 statin prescriptions in a six-week period
  • CPATCH intervention was given priority over other study initiatives offered by the pharmacy
  • All members of pharmacy staff provided informed consent
