TransitionRx: Impact of community pharmacy postdischarge medication therapy management on hospital readmission rate.

OBJECTIVES: To determine if a community pharmacy-based transition of care (TOC) program that included the full scope of medication therapy management (MTM) services (TransitionRx) decreased hospital readmissions, resolved medication-related problems, and increased patient satisfaction. DESIGN: Prospective, quasi-experimental study. SETTING: Nine Kroger Pharmacies located in Western Cincinnati. PATIENTS: Patients older than 18 years of age and discharged from two local hospitals with a diagnosis of congestive heart failure, chronic obstructive pulmonary disease, or pneumonia. Patients were recruited from two local hospitals and referred to the community pharmacy for MTM services with the pharmacist within 1 week of discharge. MAIN OUTCOME MEASURES: Pharmacists reconciled the patients' medications, identified drug therapy problems, recommended changes to therapy, and provided self-management education. At 30 days after discharge, research personnel conducted telephone surveys, using a previously validated survey instrument, to assess hospital readmissions and patient satisfaction. Pharmacist interventions and medication-related problems were documented. RESULTS: A total of 90 patients completed the study. Of these, 20% of patients in the usual care group were admitted to the hospital within 30 days compared with 6.9% of patients in the intervention group (P = 0.019). In the 30 patients who received MTM services from the pharmacist, 210 interventions were made. The overall mean patient satisfaction with the TOC process was not significantly different between patients who were seen by the pharmacist and those who were not seen by the pharmacist. CONCLUSION: Community pharmacies successfully collaborated with hospitals to develop a referral process for TOC interventions. Patients who received MTM services from the pharmacist experienced significantly fewer readmissions than patients who received usual care.

Histamine2-receptor antagonists: Rapid development of tachyphylaxis with repeat dosing.

Histamine2-receptor antagonists (H2RAs) are available over-the-counter (OTC) for the treatment and prevention of heartburn, but more than occasional, single-dose use can lead to rapid development of tachyphylaxis. The aim of this review is to assess the published evidence regarding the development of tachyphylaxis with repeat usage of H2RAs. PubMed and SCOPUS were searched across all years to identify clinical studies that examined the development of tachyphylaxis with repeated dosing of H2RAs. Although a single (first) dose of an H2RA can be effective for controlling gastric acid and preventing or relieving food-related heartburn, numerous studies confirm that tachyphylaxis, also known as tolerance, is consistently detected at the first time point assessed after the first dose, including the second day and/or second dose. Even if symptom relief is achieved with an H2RA, it may be due to desensitization of the esophagus to acid exposure, potentially providing symptom relief without significantly decreasing esophageal acid exposure. When recommending OTC drugs for treatment of frequent heartburn, clinicians should be aware of the potential for rapid development of tachyphylaxis in patients who use H2RAs for 2 or more consecutive days. Even if symptom relief is achieved, it may be due to desensitization of the esophagus to acid by the H2RA, potentially providing symptom relief without significantly decreasing esophageal acid exposure. Other strategies, such as an OTC proton pump inhibitor, may be needed to optimize management of frequent heartburn.
