Many patients not getting protective statin medications upon discharge, fewer remaining on medicine after one year
Intermountain Medical Center News Nov 18, 2017
While patients who are discharged from the hospital after treatment for heart disease, cerebrovascular disease, or peripheral artery disease, should be on statin medications to reduce their risk of reoccurrence, very few of them remain on the drugs long-termÂand many never even receive a statin prescription, according to a new study.
While patients who are discharged from the hospital after treatment for heart disease, cerebrovascular disease, or peripheral artery disease, should be on statin medications to reduce their risk of reoccurrence, very few of them remain on the drugs long-termÂand many never even receive a statin prescription, according to a new study.
Researchers from the Intermountain Medical Center Heart Institute in Salt Lake City examined the records of 62,070 adult patients with atherosclerotic cardiovascular disease from 1999 to 2013 who had survived their initial hospitalization and were followed for at least three years, or until they died.While 71% of the 62,070 patients discharged for those medical conditions were prescribed statins, just 37.4% were on statins a year later. Three years after leaving the hospital, researchers found the number had dropped to 30.1%.
Researchers said these figures are significant because statins are a class of drug therapy that lowers cholesterol levels in the blood and help reduce a patientÂs risk of additional adverse cardiovascular events.
Researchers presented findings from the study at the 2017 American Heart Association Scientific Sessions.
ÂEarlier studies had proven that a strong predictor of how well patients did in the long-term was whether they were discharged from the hospital on a statin medicine, said J. Brent Muhlestein, MD, a cardiovascular researcher at the Intermountain Medical Center Heart Institute, and lead investigator of the study.
In 1999, Intermountain Healthcare established a hospital-based discharge medication program so patients admitted for heart diseaseÂincluding coronary artery disease, heart failure, and atrial fibrillationÂwould be prescribed statin therapy to reduce the need for future admissions.
What researchers didnÂt know at that time, however, was how long patients stayed on the statins. And patients who had cerebrovascular disease or peripheral artery disease werenÂt part of the discharge medication program and usually didnÂt receive a prescription, though research showed theyÂd benefit from statins, too.
ÂBy implementing this program and discharging patients on statins, we were able to see a significant reduction in repeat hospitalizations and mortality over the next year, said Dr. Muhlestein.
Knowing whether patients who were on statins stayed on them over time was important, he said, because the benefit of the medication hinges on continuing to take it.
In their current study, the Intermountain Medical Center Heart Institute researchers decided to see how many patients remained on statins and to identify reasons why patients who should be taking that type of drug therapy were not.
Most patients in the new study had coronary artery disease (69%), compared to cerebrovascular disease (18.6%) and peripheral artery disease (12%).
Besides determining whoÂd been prescribed statins and whether they remained on them, researchers also used multivariable analysis to identify the independent predictors of long-term statin use.
In all, fewer than one-third of patients whoÂd been discharged with an atherosclerotic cardiovascular disease were on statins after three years.
ÂThatÂs a major treatment gap, said Dr. Muhlestein.
Reasons patients werenÂt on the medications were usually non-medical, Intermountain Medical Center Heart Institute researchers found:
