Potassium testing poses another barrier
Even though the alerts substantially improved MRA prescribing, 70% of patients deemed MRA eligible in the alert subgroup still failed to receive a prescription. One additional barrier specific to MRA prescribing is the need it triggers for serial laboratory testing to monitor serum potassium levels. “Potassium testing generates additional work outside the index visit, which along with the risk for hyperkalemia exists as a barrier,” commented Lee R. Goldberg, MD, a heart failure specialist and professor at the University of Pennsylvania in Philadelphia. “This may be the next aspect to focus on to improve MRA uptake,” he said as a designated discussant for the report.

“It’s not enough to just prompt medication treatment. We also need to prompt appropriate laboratory testing,” noted Dr. Fonarow.
He also said that the approach tested by Dr. Mukhopadhyay could now be expanded to outpatient cardiologists. “The onus is on everyone involved in caring for patients with HFrEF failure to explain why maximum effort is not being made to deploy” all of the guideline-directed medical therapies for the disorder.
EHR alerts “are one way to bridge the prescribing gap, but we need multiple approaches so that all eligible patients receive guideline-directed medical therapy,” Dr. Fonarow said.
