Underutilization of Aldosterone Antagonists in Heart Failure.

Background: Treatment with an aldosterone antagonist (AA) has been shown in multiple trials to reduce heart failure (HF)-related morbidity, mortality, and hospital readmission. American College of Cardiology Foundation (ACCF) and American Heart Association (AHA) treatment guidelines recommend the use of an AA in all HF patients with an ejection fraction ≤35% and no known contraindication. Several studies have documented underuse of AA. Objectives: To determine the proportion of patients who received AA therapy consistent with the ACCF/AHA guidelines. Secondary objectives included determining the proportion of patients who received an AA inconsistent with guidelines and 30- and 90-day readmission rates. Methods: A retrospective chart review was conducted of patients admitted to an inner city academic medical center with a diagnosis of HF between August 16, 2011, and June 5, 2013. Results: A total of 346 HF admissions (87.6% African American) were evaluated. Use of an AA at discharge was consistent with guidelines in 31% of patients. A total of 121 patients (35%) were discharged on an AA. Among the remaining 225 patients who were not discharged on an AA, 170 (75.6%) had no contraindication to therapy. Sixty-one patients were readmitted within 30 days, and a total of 108 patients were readmitted within 90 days. There were no significant differences in readmission rates between patients who were discharged on AA therapy and those who were not. Conclusion: AAs are still underutilized in the treatment of HF.

Action plans to reduce hospitalizations for chronic obstructive pulmonary disease exacerbations: focus on oral corticosteroids.

OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is associated with a huge burden of suffering and healthcare expenditures. Patients hospitalized due to COPD have increased risk of death. Starting in 2015, reimbursements by the Centers for Medicaid Medicare Services will be significantly reduced to hospitals with excess 30 day readmissions for COPD. Oral corticosteroid (OCS) therapy is established in improving outcomes in COPD patients treated in the emergency department and hospital. The objective of this article is to review the evidence evaluating home OCS treatment of COPD exacerbations as part of a comprehensive self-management action plan. METHODS: We reviewed the English literature via PubMed, Embase, and Scopus using the search terms: chronic obstructive pulmonary disease exacerbations AND: oral corticosteroids, prednisone, prednisolone, methylprednisolone, treatment, self-management, disease management, written action plans. When pertinent articles were found, we reviewed the relevant articles cited. FINDINGS: Two randomized trials enrolling 933 patients provide evidence of reduced rates of hospitalization by using comprehensive COPD action plans, including OCS therapy. Three trials with 790 patients enrolled did not reveal reduced rates of hospitalization. Among all five trials together, there were no differences in deaths (76 in the intervention groups [home action plans]; 81 in the usual care groups). Additional studies not assessing hospitalizations have found home use of OCSs increases time to the next exacerbation and decreases recovery time. CONCLUSION: Further randomized trials are needed to establish that home use of OCS therapy, as part of a comprehensive action plan, reduces the rate of hospitalizations. Such action plans should include structured patient education, early initiation of OCSs, oral antibiotics, and frequent telephone reinforcement and support from case management.

Incorrect use of peak flow meters: are you observing your patients?

BACKGROUND: Monitoring peak expiratory flow (PEF) values is one option as part of asthma action plans per national guidelines. PEF assessment is also recommended in emergency department and hospitalized patients. Incorrect use of peak flow meters (PFM) has obvious implications for appropriate decisions by patients and clinicians. METHODS: We searched the English literature via PubMed and SCOPUS using the following search terms: PEF maneuver; incorrect use of PFM. When pertinent articles were found, we assessed publications cited in those papers. All studies related to incorrect use of PFM in patients with asthma were included. RESULTS: Nine studies have reported errors in performing the PEF maneuver, including three pediatric and six adult studies. Errors were found at most steps of the maneuver, and inability to perform all steps correctly was common in these investigations. Examples of errors included failure to inhale fully or give maximum effort on exhalation, accelerating air with the tongue and buccal musculature, and performing only one attempt versus three. Gender differences in correct use of PFM are suggested by three adult studies. One study described falsifying PEF values by manipulating the PFM indicator, and another investigation assessed the PEF maneuver in two positions in bed versus the correct posture of standing. CONCLUSION: Many pediatric and adult patients do not use PFM correctly. Clinicians should regularly observe patients use PFM to detect errors and help ensure correct use and accurate PEF measurements.
