Abstract
An innovative approach for the early detection of oral cancer and precancer within the context of the primary health care system has been field tested in Sri Lanka. The overall compliance in accepting this particular PHC approach for cancer screening, as estimated by arrival at a referral centre manned by consultant staff, was 54.1%. Nearly 80% of those who turned up without needing an additional reminder, did not within the first 2 weeks of case finding. There was a variation in the degree of compliance depending on the primary health care worker who did the screening and referral. Compliance was greater when the screening area was nearer to the referral centre and in subjects who were diagnosed as having a more advanced stage of the disease. Certain practical considerations that contributed to noncompliance were identified. Postal reminders were seen to increase overall compliance by 10.9%.
