The purpose of this study is to measure the rate of compliance of patients

with chronic diseases (diabetes mellitus and hypertension) who attend the clinics

of the ministry of health (MOH) in northern Palestine. Three hundred and twenty

one (321) patients are personally interviewed using graded questionnaire to assess

their compliance. The results has shown that there is 6.5% non-compliance, 52.4%

poor/partial compliance and 42.1% good compliance among the tested sample. The

percentage of noncompliance is correlated with the percentage of illiteracy and

lack of drug and disease knowledge among the tested sample. Gender and place of

living are not influential while age, education, and type of disease are influential on

patient’s rate of compliance. Diabetic patients have better overall rate of compliance

than hypertensive patients. These results should encourage the health authorities

in Palestine to implement techniques that would monitor and enhance the patient’s

compliance. This would ultimately reduce national health costs and increase the

patient’s desired therapeutic outcome.
