Feasibility, safety and clinical efficiency of optometric service pathways at primary and tertiary care level in ampang, malaysia: A pilot study

Abstract

Aim: To evaluate feasibility, safety, and clinical efficiency of optometrists in conducting diabetic retinopathy screening and ocular health screening. Methods: This was a prospective observational trial study of newly developed optometric service pathways established at a community health clinic for diabetic retinopathy screening and a hospital ophthalmology clinic for ocular health screening. The study was carried out to assess the feasibility and safety of eye examinations conducted by optometrists. Patients were examined by optometrists using a standard eye examination at both clinics and re-examined by ophthalmologists as the reference standard. Optometrists recorded diagnoses of ocular conditions and classified referral urgency for each patient and these were compared with the diagnoses made by ophthalmologists, who were masked to the optometrists’ findings. Results: There was a high concordance of 87.0% (95% CI 80.4%-93.6%) for the diagnoses between the optometrists and ophthalmologists. Of 26 patients considered by the optometrists to need ophthalmology referral, 23 were agreed as such by the ophthalmologists, giving good agreement, κ = 0.76 (95% CI 0.53-0.94) between the optometrists and ophthalmologists on referral classification. Agreement by the ophthalmologists for referral urgency classifications (very urgent/urgent or non-urgent) was very good (κ = 0.85, 95%CI 0.62-1.00). Conclusions: Ocular health examination by optometrists using optometric-eye care pathways is feasible and safe. Optometrists showed strong agreement with ophthalmologists when diagnosing patients who had a range of ocular conditions. Optometrists were also able to triage referrals and their urgency accurately, suggesting that they could play an extensive role as primary eye care providers, thus reducing unnecessary referrals to ophthalmology clinics.
