Background and objectives
Patients with CKD are at risk for adverse drug reactions, but
effective community-based preventive programs remain elusive. In this
study, we compared the effectiveness of two digital applications
designed to improve outpatient medication safety.
Design, setting, participants, & measurements
In a 1-year randomized controlled trial, 182 outpatients with
advanced CKD were randomly assigned to receive a smartphone preloaded
with either eKidneyCare (n=89) or MyMedRec
(n=93). The experimental intervention,
eKidneyCare, includes a medication feature that prompted patients to
review medications monthly and report changes, additions, or medication
problems to clinicians for reconciliation and early intervention. The
active comparator was MyMedRec, a commercially available, standalone
application for storing medication and other health information that can
be shared with patients' providers. The primary outcome was the rate of
medication discrepancy, defined as differences between the patient’s
reported history and the clinic’s medication record, at exit.
Results
At exit, the eKidneyCare group had fewer total medication
discrepancies compared with MyMedRec (median, 0.45; interquartile range,
0.33–0.63 versus 0.67; interquartile range, 0.40–1.00;
P=0.001), and the change from baseline
was 0.13±0.27 in eKidneyCare and 0.30±0.41 in MyMedRec
(P=0.007). eKidneyCare use also reduced
the severity of clinically relevant medication discrepancies in all
categories, including those with the potential to cause serious harm
(estimated rate ratio, 0.40; 95% confidence interval, 0.27 to 0.63).
Usage data revealed that 72% of patients randomized to eKidneyCare
completed one or more medication reviews per month, whereas only 30% of
patients in the MyMedRec group (adjusted for dropouts) kept their
medication profile on their phone.
Conclusions
In patients who are high risk and have CKD, eKidneyCare
significantly reduced the rate and severity of medication discrepancies,
the proximal cause of medication errors, compared with the active
comparator.
