Identification of psychological morbidity in older people in primary care by practice nurses

Older people with psychological morbidity generally first present to health services in primary care, where they are increasingly seen by primary care nurses. In order to evaluate primary care nurses' identification of psychological morbidity, 190 older patients attending eight practice nurses completed the General Health Questionnaire (GHQ) and the practice nurses made an assessment as to the presence or absence of psychological problems. The practice nurses identified only 26% of probable cases of psychological morbidity identified by the GHQ. Their threshold for identification was high, rating only 12% of patients as experiencing psychological problems compared to 29% probable cases identified by the GHQ, and their accuracy was low (kappa for agreement between GHQ and nurse ratings = 0.23). Likelihood of identification depended on length and type of visit. The findings suggest that it may be unrealistic to expect practice nurses, without additional training and reorganisation of their work, to identify more than a minority of older patients with psychological morbidity in the course of their routine work.
