Assessing Guideline-Directed Medication Therapy for Heart Failure in End-Stage Renal Disease.

BACKGROUND: Treatment of heart failure with reduced ejection fraction (HFrEF) requires guideline-directed medication therapy (GDMT) consisting of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker in combination with an indicated beta-blocker. There is concern that end-stage renal disease (ESRD) patients are not being prescribed GDMT. The study aim was to determine whether outcomes differ for patients with HFrEF and ESRD receiving GDMT compared to those not receiving GDMT. MATERIALS AND METHODS: Adult patients with ESRD and HFrEF admitted to a tertiary teaching hospital over a 2-year period were included. Patients were categorized into GDMT or non-GDMT groups based on their home medications. The length of stay (LOS), mortality, and 30-day hospital readmissions were compared between groups. The incidence of hyperkalemia, hypotension and bradycardia were also evaluated. RESULTS: A total of 109 patients were included: 88% African-American, 61% males, median age 63 (28-93) years with 25 in the GDMT group and 84 in the non-GDMT group. The LOS did not differ between the GDMT (5 days; 3-14) compared to the non-GDMT group (7 days; 3-28), P = 0.14. Thirty-day hospital readmission and in-hospital mortality were also similar. Hypotension occurred less frequently in the GDMT group compared to the non-GDMT group, 4% versus 27% (P = 0.01). CONCLUSIONS: Although there were no differences in the primary outcomes, the shorter LOS in the GDMT group may be clinically significant. The fact that most patients with ESRD and HFrEF were not receiving GDMT is a finding that requires further evaluation.

Impact of a discharge medication therapy management program in an extended care hospital.

OBJECTIVES: To study the feasibility and effectiveness of a discharge medication therapy management program. DESIGN: Quasi-experimental pre-post study design. SETTING: Thirty-six-bed hospital within an extended care hospital. PARTICIPANTS: All patients admitted to facility from January 2009 to December 2009 (control) and February 2010 to January 2011 (program). INTERVENTION: Pharmacist review of anticipated discharge following 18-20 days of stay, with suggested medication changes communicated to physicians via patient chart. Agreed changes were implemented on the next day. MEASUREMENTS: Patient readmissions within 30, 60, and 90 days into the hospital system. Medication interventions were quantified as to type. RESULTS: During the control period, 432 patients were followed, and during the intervention period, 369 patients were followed, with similar lengths of stay. In the intervention period, 565 medication interventions were attempted on 216 patients, with an 85.3% acceptance rate. The major intervention was discontinuation of medications. Mean maintenance medications per patient decreased from 10.57 to 9.46 in the intervention group, and daily medication doses per patient decreased from 17.95 to 15.73 (P < 0.001). Readmission rates were lower at 30 and 60 days in the intervention group, with a 90-day overall decrease in system readmission rate from 51% to 39% (P < 0.001). CONCLUSION: The discharge medication management program was successful in decreasing both number and type of discharge medications via pharmacist intervention. Overall, patient system readmission rates were also significantly decreased in the intervention period.

Comparison of initial warfarin response in obese patients versus non-obese patients.

Achieving therapeutic anticoagulation with warfarin is complicated by substantial inter-patient and intra-patient variability with numerous factors known to influence dose requirements. Obesity is one factor for which there remains no study to date investigating its initial effect on warfarin response assessed by INR, stratified by BMI category in hospitalized patients. To compare initial warfarin response between obese and non-obese patients by evaluating average daily dose (ADD), time required to attain therapeutic INR, and mean discharge dose (MDD), stratified by BMI category. A retrospective review was conducted to evaluate initial warfarin response in hospitalized patients of different BMI categories initiated on warfarin with ≥4 consecutive days of therapy and managed by pharmacy dosing service. 211 patients were included (10 underweight, 45 normal weight, 48 overweight, 71 obese, 37 morbidly obese). Across BMI categories, the percentage of patients attaining therapeutic INR prior to discharge differed (p = 0.0004) with 71.1 % of normal weight therapeutic compared to 42.3 % of obese and 38 % of morbidly obese. Within BMI categories, when comparing ADD between patients therapeutic and subtherapeutic at discharge, no differences were observed, except among overweight patients (5.6 ± 0.3 vs. 7 ± 0.4 mg, p = 0.0143). Compared to normal weight, obese and morbidly obese required a significantly longer median time to achieve therapeutic INR (8 and 10 days vs. 6 days) and a higher ADD (6.6 ± 0.3 and 7.6 ± 0.5 vs. 5 ± 0.3 mg) and MDD (6.7 ± 0.5 and 6.7 ± 0.7 vs. 4.4 ± 0.5 mg). Compared to normal weight, obese and morbidly obese patients had a decreased initial response to warfarin.
