Credentialing & privileging an important factor for diagnostic accuracy of diabetic retinopathy screening in the health clinics of Penang.

MO with C&P showed better accuracy than MO without C&P. This study suggests that MOH should emphasise the C&P when performing this procedure in health clinics.

This study also indicates that evaluating DR screening programs in health clinics is necessary nationwide.
