Did You Know?? Fear of Meds Reduces Patient Adherence
Patients may decide not to fill a prescription or take a medication because of potential adverse effects.
Dr. Zanni is a psychologist and health-systemsspecialist based inAlexandria, Virginia.
According to a recent survey byHarris Interactive, 46% ofadults are extremely or veryconcerned about adverse reactionswhen taking prescription drugs asdirected. The same Harris poll foundthat patients' fears impact adherence.The following were reported among alladults who have ever taken prescriptiondrugs1:
- 35% decided not to take a medicationbecause of potential adverse effects
- 27% decided not to fill a prescriptionbecause of potential adverse effects
- 94% stopped taking a medicationafter they experienced an adverseeffect
Although 46% of patients have fearsconcerning potential adverse effects,pharmacists spend <25% of their timeconsulting with patients.2 Reasons forthis disconnect are well known by allpharmacists—understaffing and timemanagement.
What Do Patients Want to Know?
Patients are concerned with 4 essentialaspects with regard to medicationinformation: the agent's purpose, sideeffects, directions for taking it, and thedos and don'ts associated with theagent.3 Most patients prefer receivinginformation from practitioners, but 160million Americans also turn to theInternet; 84% of all online adults searchthe Internet an average of 5.7 timesper month for health information, andup to 55% of this group query physicianson Internet information.4 Patientsalso react to media health news; it isnot unusual for patients to bombardpractitioners with questions aftermedia reports on FDA recalls andblack-box warnings. It should be notedthat 86% of Americans aged 50 andolder hold favorable opinions of pharmacists—a statistic that exceedsfavorable opinions of physicians (84%).5
