Median age at time of MRA initiation was 73 years, and 37.1% were women. Spironolactone accounted for 99.4% of MRA use. Initial ambulatory MRA dispensing occurred at hospital discharge in 70.0% of cases. In the 30 days before MRA initiation, 94.3% of patients had a K or Cr measurement. Preinitiation K was &gt;5.0 mmol\/L in 1.4% and Cr &gt;2.5 mg\/dL in 1.7%. In the 7 days after MRA initiation among patients who remained alive and out of the hospital, 46.5% had no evidence of K measurement; by 30 days, 13.6% remained untested. Patient factors explained a small portion of postinitiation K testing (\n              <jats:italic>c<\/jats:italic>\n              -statistic, 0.67).\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Although laboratory monitoring before MRA initiation for heart failure with reduced ejection fraction is common, laboratory monitoring after MRA initiation frequently does not meet guideline recommendations, even in patients at higher risk for complications.
