1.  Completeness of prescription information in US commercial claims databases 
Pharmacy commercial claims databases are widely used for pharmacoepidemiologic research. However, concerns have been raised that these databases may not fully capture claims for generic medication as a result of patients filling outside the context of their insurance. This has implications for many research activities and quality improvement programs. We sought to estimate the percentage of missing drug claims in US commercial claims data using a novel design.
Using a large US commercial insurance database, we examined the completeness of warfarin prescription claims among patients with atrial fibrillation receiving regular medical follow-up and testing to manage warfarin dosing. We examined 14 different 6-month cross sections. Each cross section was treated independently to identify patients with at least 2 outpatient diagnoses of atrial fibrillation, 2 international normalized ratio tests, and 1 pharmacy claim. Trends in the percentage of patients with prescription claims for generic and branded warfarin were compared by year and 6-month periods using chi-square tests and generalized linear models adjusting for patient characteristics.
Out of 111,170 patients, the percentage of patients with any warfarin drug decreased slightly from 91.7% (95% CI: 91.0, 92.4) in early 2003 to 87.1% (95% CI: 86.7-87.6) in late 2009 (χ2=93.8, p<0.0001). Over the same interval, the proportion of patients with generic warfarin exposure appearing increased significantly, while the proportion of patients with branded warfarin exposure decreased significantly.
Our study supports the possibility that some prescriptions may not be captured in US commercial insurance databases.

2.  Design of a medication management program for Medicare beneficiaries: Qualitative findings from patients and physicians 
The quality of pharmacologic care provided to older adults is less than optimal. Medication therapy management (MTM) programs delivered to older adults in the ambulatory care setting may improve the quality of medication use for these individuals.
We conducted focus groups with older adults and primary care physicians to explore: (1) older adults' experiences working with a clinical pharmacist in managing medications, (2) physician perspectives on the role of clinical pharmacists in facilitating medication management, and (3) key attributes of an effective MTM program and potential barriers from both patient and provider perspectives.
Five focus groups (4 with older adults, 1 with primary care physicians) were conducted by a trained moderator using a semi-structured interview guide. Each participant completed a demographic questionnaire. Sessions were recorded, transcribed verbatim, and analyzed using qualitative analysis software for theme identification.
Twenty-eight older adults and 8 physicians participated. Older adults valued the professional, trusting nature of their interactions with the pharmacist. They found the clinical pharmacist to be a useful resource, thorough, personable, and a valuable team member. Physicians believe the clinical pharmacist fills a unique role as a specialized practitioner, contributing meaningfully to patient care. Physicians emphasized the importance of effective communication, pharmacist's access to the medical record, and a mutually-trusting relationship as key attributes of a program. Potential barriers to an effective program include poor communication and lack of familiarity with the patient's history. The lack of a sustainable reimbursement model was cited as a barrier to widespread implementation of MTM.
This study provides information to assist pharmacists in designing MTM programs in the ambulatory setting. Key attributes of an effective program include one that is comprehensive, addressing all medication-related needs over time. The clinical pharmacist's ability to build trusting relationships with both patients and providers is essential.
