Background: In recent years, telemedicine has gained increasing importance in the delivery of pharmaceutical care. The use of video technologies for remote communication between different parties offers the potential to meet the future challenges which arise from the increase in elderly and chronically ill patients. However, the influence of these technologies on patient-related outcomes in pharmaceutical care is not yet sufficiently known.
Method: In December 2018 a systematic literature search was conducted in the databases Medline, Cochrane Library and PubPharm. Randomized controlled trials were considered, which investigate real-time video conferencing between pharmacists on the one hand and patients or other healthcare providers on the other hand. The influence on patient related outcomes compared to standard care was assessed. The bias potential was evaluated using the Cochrane Risk-of-Bias instrument. A total of 4 randomized controlled trials could be included.
Results: The studies describe partly complex intervention settings with adults and adolescents suffering from asthma, chronic renal failure, HIV infection, hyperlipidemia, hypertension and/or diabetes. None of the studies considers the interprofessional communication of pharmacists with other service providers. No influence on clinical or psychological endpoints was found. In some cases, an increase in adherence and correct medication use is evident. Healthcare utilization is not influenced. In all studies there is an increased risk of systematic bias.
Discussion: Teleconsultations with pharmacists can rather be used to ensure the general provision of pharmaceutical care than to improve patient-related outcomes. Further studies are necessary to fully depict the influence of telemedical interventions in pharmaceutical care.
