Using clinical pharmacist specialists (CPS) for the management of therapy with direct-acting antivirals (DAAs) in patients with hepatic C virus (HCV) infection leads to improved sustained virologic rates (SVRs), according to a study published in the Journal of Pharmacy Practice.
Researchers at the Veterans Affairs (VA) Sierra Nevada Health Care System assessed the potential roles and outcomes of an outpatient-based HCV treatment clinic (HCVTC) managed by a CPS in partnership with an infectious disease physician.
Between November 1, 2014, and November 30, 2015, a total of 132 veterans infected with HCV were managed by a CPS who engaged in pretreatment screening, drug selection, patient education, medication counseling, drug therapy monitoring, drug utilization review, addressing issues on drug adherence, and routine and posttreatment follow-up of patients.
During this time, 87 patients were treated with ledipasvir/sofosbuvir, 29 patients were treated with paritaprevir/ritonavir/ombitasvir + dasabuvir, and 16 patients were treated with sofosbuvir-based regimens. After 12 weeks of treatment, an SVR rate of 92%, 100%, and 93.8%, was achieved for each of the treatment regimens, respectively.
The overall SVR rate was 94% across all genotypes, with an SVR rate of 93% in treatment-naive patients, 96% in treatment-experienced patients, 93% in patients without cirrhosis, and 94% in patients with compensated cirrhosis.
In comparison, a report based on VA national electronic data from 17,487 veterans with HCV infection treated with similar DAA-based regimens from January 1, 2014, to June 30, 2015, showed an overall SVR rate of 91% across all genotypes, with an SVR rate of 91% in treatment-naïve patients, 90% in treatment-experienced patients, 92% in patients without cirrhosis, and 87% in patients with compensated cirrhosis.
The authors concluded that “the collaborative partnership between an [infectious disease physician] and CPS displayed a concerted effect in achieving higher SVR rates and HCV treatment success in our HCVTC patients.”
