This study reports data from 50 practices (3550 patients) in Lanarkshi
re taking part in an audit of diabetes care. Data were obtained by rev
iew of general practitioner records and the correspondence from consul
tants and opticians contained in them. The principal study measures ex
amine the process of care. Overall levels of performance were low: onl
y 35.5 % of patients had visual acuity and 54.5 % fundoscopy recorded
in the previous year. Significantly better results were observed for b
oth examinations in those few practices which performed these examinat
ions in more than 10 % of their patients (51.4 % vs 32.0 % (mean diffe
rence 19.4, 95 % CI 16.1-23.7) for visual acuity and 65.7 % vs 53.3 %
(mean difference 12.4, 95 % CI 3.0-21.8) for fundoscopy. Less than hal
f of diabetic patients in Lanarkshire currently receive adequate scree
ning for the ocular complications of diabetes. Most practices rely on
hospital diabetic and ophthalmology services. Where practices undertak
e ocular examination of patients, this is currently in addition to tho
se services provided elsewhere.
