A Safety Audit of the First 10 000 Intravitreal Ranibizumab Injections Performed by Nurse Practitioners

Purpose: To evaluate the safety of a nurse practitioner (NP)-delivered injection service for the treatment of wet age-related macular degeneration (wAMD) with ranibizumab.

Methods: An evaluation of medical staffing resources for providing an injection service for wAMD highlighted difficulties covering lists. An alternative strategy of an NP-delivered injection service was evaluated. Two suitable NPs with previous extensive experience in minor surgical procedures were identified. The department's senior vitreo-retinal consultant supervised the NP's training programme. A prospective safety audit was conducted for the first 5.5 years of the service.

Results: The NPs administered 10 006 injections in the first 5.5 years of the service (1 May 2008 to 8 October 2013). This represented 84.1% of the total injections performed during this period. Four patients developed presumed infectious endophthalmitis (1 was culture positive and 3 were culture negative). The incidence of post-injection endophthalmitis was 0.04%. There was no evidence of lens touch, retinal detachment, or systemic thrombo-embolic events.

Conclusions: Carefully selected and well-trained NPs are capable of delivering a safe and effective wAMD injection treatment service. This work demonstrates how such a service can be established and provides safety data that other units can use as a benchmark when evaluating their own practice.
