Evidence-Based Reduction of Heart Failure Events With the Involvement of Pharmacists

Arch Intern Med. 2000;160(11):1698. doi:

The recent report by Gattis et al1 describing how the role of pharmacists on a multidisciplinary heart failure team can improve the outcomes of heart failure provides an excellent example of the multidisciplinary approach to chronic diseases. Studies involving the participation of pharmacists in the treatment of hypertension have revealed that 55% of patients with uncontrolled hypertension at baseline achieved their goal blood pressure (<140/90 mm Hg) after 6 months in the intervention arm compared with 20% in the control arm.2 The number needed to treat (NNT) is a term that has gathered prominence in recent years, and the NNT has been used to determine clinical significance in many studies. The NNT is defined as the number of patients needed to achieve one favorable outcome.3 The NNT is calculated as 1 divided by absolute risk reduction.
