Background: beta-blockers (BB) in the treatment of heart failure (HF) are frequently underprescribed and underdosed, perhaps because of recommendations for office visits at each dose change. In previous work, we demonstrated the feasibility of remote telephonically assisted BB titration and found favorable effects on morbidity, time to target dose, and low withdrawal rates. In the current expanded evaluation, we reasoned that a structured remote telephonic titration protocol would achieve outcomes comparable to US Carvedilol Trials in regard to optimal dose, titration time, and morbidity.
Methods: Seventy HF patients were initiated on BB therapy (carvedilol). Before therapy, patients were instructed on BB side effects, pulse taking, and weight monitoring. Patients reported weights, vital signs, and symptoms 3 times per week by phone. Advanced practice nurses counseled, educated, and reminded patients to increase their dose every 2 weeks until target doses were reached.
Results: A total of 96% reached a therapeutic dose (6.25 mg twice daily). Moreover, 71% of patients reached target doses of 25 mg twice weekly in approximately 8 weeks. No HF hospitalizations occurred during remote titration.
Conclusions: The use of advanced practice nurses, titration protocols, and telemanagement technologies may improve the number of HF patients initiated and treated with appropriate doses of BB.
