A systematic review of synchronous telepharmacy service models for adult outpatients with cancer

BACKGROUND

Telephone and videoconsults are known synchronous telepharmacy modalities being used to respond to the demand for outpatient pharmacy services. However, little is known about the evidence for cancer telepharmacy service models.

OBJECTIVES

To review existing evidence regarding synchronous telepharmacy service models for adult outpatients with cancer, with a secondary focus on outcomes, enablers, and barriers.

METHODS

A PROSPERO registered systematic review was conducted using PubMed, CINAHL, and EMBASE in March 2023. Key search terms included pharmacy, telepharmacy, and outpatient. During article selection in Covidence, an extra inclusion criterion of synchronous cancer-focused services was applied; data extraction and narrative analysis were then performed.

RESULTS

From 2129 non-duplicate articles, 8 were eligible for inclusion, describing 7 unique patient populations. The service models included pre-treatment medication history taking, adherence monitoring, toxicity assessment, and discharge follow-up. Studies found synchronous telepharmacy services can improve timeliness of care, optimise workload management, and provide individualised and convenient efficacy monitoring and counselling. One study of 177 patients on immune checkpoint inhibitors found 38% of the 726 telephone consults involved at least one intervention. When videoconsults were compared directly with telephone consults for pre-treatment medication history, it was found scheduled videoconsults had a significantly higher success rate than unscheduled telephone consults, and that videoconsults also represented increased funding and equivalent time efficiency. When telephone follow-up was compared to no follow-up, improved treatment adherence was seen, and progression-free survival was significantly higher for the telephone group (6.1 months vs 3.7 months, p = 0.001). Reported enablers included physician buy-in, staff resources, and correct utilisation of technology, while identified barriers included time investment required and technical issues.

CONCLUSION

Both telephone and videoconsult modalities are being used to deliver synchronous telepharmacy services across a range of outpatient services. Although more evidence is needed, data to date supports positive service benefits and enhanced care.
