Background:
Pharmacist interventions have been shown to have an impact on reducing readmission rates, however further research is necessary to target resources to high-risk populations and determine the most effective bundle of interventions.
Objective:
To evaluate the effect of a pharmacist-bundled intervention on 30-day readmission rates for high-risk patients with pneumonia.
Methods:
A pilot study with a historical control conducted at a community, teaching-affiliated medical center. Up to 65 selected subjects were included if they had pneumonia and any of the following high-risk criteria: admission within 6 months, at least 5 scheduled home medications, chronic obstructive pulmonary disease (COPD), or heart failure. A retrospective chart review was conducted to compile the historical control group that received usual care between June and November 2013. Patients admitted from December 2013 through March 2014 were reviewed to receive a bundled intervention. The primary outcome was 30-day readmission rates. Risk factors and reasons for readmission, pharmacist clinical interventions, and the time interval between discharge and readmission were also evaluated.
Results:
A trend toward a reduced 30-day readmission rate was observed in the intervention group (n = 43) compared to those who received usual care (n = 65) (27.9% vs 40.0%; relative risk [RR], 0.6977; 95% CI, 0.3965-1.2278; P = .2119). The most commonly identified high-risk inclusion criteria were having at least 5 scheduled home medications and COPD. The time interval between discharge and readmission did not considerably differ between groups (10.8 vs 10.6 days).
Conclusions:
The pharmacist-bundled intervention was associated with a reduced 30-day readmission rate for high-risk patients with pneumonia.
