Impact of clinical pharmacy services on outcomes and costs for indigent patients with diabetes.

OBJECTIVES: To provide a review of the outcomes and costs in patients seen by Clinical Pharmacy Specialist (CPS) Certified Diabetes Educators in ambulatory care for diabetes management. STUDY DESIGN: A retrospective chart review. METHODS: All patients discharged by a CPS for diabetes management between January 1, 2010, and December 31, 2013, were included. RESULTS: A total of 915 patients were discharged from CPS services. The majority of patients had type 2 diabetes (98.7%) and were female (63.1%), Hispanic (53.3%), and on average, were aged 56 years. The patients were seen by the CPS for approximately 5.3 face-to-face visits, and by their provider for 1.9 face-to-face visits. The average difference from baseline for glycated hemoglobin was -2.6%, while the average systolic and diastolic blood pressures improved by -8 mm Hg and -3 mm Hg, respectively. The major lipid parameters also reported improvement, averaging -23 mg/dL for total cholesterol, -54 mg/dL for triglycerides, -15 mg/dL for low-density lipoprotein cholesterol, -23 mg/dL for non-high-density lipoprotein cholesterol (non-HDL-C), and +0.8 mg/dL for HDL-C. Overall, the average difference from baseline to final visit for the numbers and costs of medications and diabetes supplies per patient increased slightly. Medication adherence also improved each year in patients with diabetes. CONCLUSIONS: The CPSs directly impact patient care through improvements in clinical outcomes. They help patients achieve disease-state goals for diabetes, hypertension, and dyslipidemia through a variety of clinical interventions and by promoting medication adherence. These data demonstrate the significant positive impact to the institution that clinical pharmacy services have in diabetes management.

Over-the-counter fish oil use in a county hospital: Medication use evaluation and efficacy analysis.

BACKGROUND: Little is known about the use and effectiveness of over-the-counter (OTC) fish oil supplements for triglyceride (TG) lowering. OBJECTIVES: To (1) perform a medication-use evaluation (MUE) and (2) assess the efficacy of OTC fish oil. METHODS: Retrospective, observational cohort study using electronic medical records and the pharmacy database from Parkland Health and Hospital System in Dallas, Texas. Parkland is a tax-supported county institution that provides patients with single-brand OTC fish oil. Two separate analyses were conducted. Six hundred seventeen patients (prescribed fish oil between July 1, 2012, and August 31, 2012) were included in the MUE analysis and 235 patients (109 fish oil, 72 fenofibrate, and 54 gemfibrozil, prescribed between January 1, 2012, and July 31, 2013) were included in the efficacy analysis. The main outcome measure for the MUE was fish oil prescribing habits including dosages and patient adherence, as defined by medication possession ratio. The main outcome measure for the efficacy analysis was change in lipids measured using the last value before fish oil treatment and the first value after fish oil treatment. RESULTS: MUE: 617 patients received prescriptions for OTC fish oil. Sixty-four percent were prescribed a total daily dose of 2000 mg. Only 25% of patients were adherent. Efficacy analysis: despite being prescribed suboptimal doses, fish oil reduced TGs by 29% (95% confidence interval, 34.3-22.7). Compared with fish oil therapy, fibrate therapy resulted in a greater TG reduction: 48.5% (55.1-41.0) with fenofibrate and 49.8% (57.6-40.5) with gemfibrozil (P < .0001, both medications compared with fish oil). CONCLUSIONS: Health care providers prescribe suboptimal doses of fish oil, and adherence is poor. Even at low doses (2 g/d), though, fish oil lowers TGs by 29%.
