The concept of the informed health-care 'consumer' rests on the availa
bility of comprehensible information. While various bodies have made i
nformation available, its quality is mixed. Information is sometimes u
ntrustworthy, incomprehensible, or simply forgotten by patients. An un
derstandable record of advice is more likely to bring about compliance
with treatment and lessen the need to revisit the surgery. This is a
report of the revision of health-care information leaflets and their t
esting on 59 volunteers (61-81 years old). Presentation, reading ease
and understanding were considered. The goal of making health-care info
rmation comprehensible was achieved. Guidelines for revising such mate
rial are described and illustrated. The informed consumer goal may be
achievable if writers of health-care information attend to communicati
on as much as to the adequacy of their medical advice.
