all diagnoses were listed in Table 7.2. 5HVSLUDWRU\ SUREOHPV ZHUH WKH PRVW IUHTXHQWO\ PDQDJHG GLDJQRVHV DFFRXQWLQJ IRU RI DOO

FDWHJRULVHGDVXQVSHFLÀHG Minor differences were noted between public and private clinics in relation to the distribution of diagnoses
by ICPC-2 chapter. For instance, endocrinemetabolic and cardiovascular problems were more frequently managed in public clinics and accounted for higher proportion of all diagnoses in public compared to
private clinics. On the other hand, respiratory and digestive problems were more commonly managed at private clinics. Nearly all chronic diseases were less frequently reported at private clinics and comprised
a lower percentage of all diagnoses managed in private clinics.
