Background. The aims were to determine the prevalence of psychiatric m
orbidity among primary care attenders in a poor suburb of Santiago and
to study the relationship with health service use. Method. A cross-se
ctional survey was made of 163 consecutive attenders to a primary care
clinic. Results. Eleven per cent of the sample gave a psychological r
eason for consultation and the prevalence of psychiatric morbidity was
53%, defined using the revised Clinical Interview Schedule. Women and
those of lower socio-economic status were at higher risk. Physicians
recognised 14% of the psychiatric morbidity. Attenders with psychiatri
c morbidity consulted more frequently. Conclusions. There is a need to
improve the recognition and management of psychiatric morbidity in pr
imary care in Chile and other less developed countries. This could lea
d to the more efficient use of scarce health care resources in primary
care.
