Psychotropic drug therapy knowledge of health care practitioners.

The psychotropic drug therapy knowledge of eight types of health care practitioners was studied. An examination, dealing with case studies of schizophrenia, depression and mania, was developed. The categories of practitioners were: (1) clinical pharmacists in psychiatric practice, (2) psychiatrists, (3) physicians (nonpsychiatrists), (4) hospital pharmacists in mental health institutions, (5) hospital pharmacists in nonmental health institutions, (6) community pharmacists, (7) nurses in mental health institutions, and (8) nurses in nonmental health institutions. The specific areas of drug knowledge tested were: diagnosis; drug selection; side effects; adverse reactions; monitoring parameters; influence of other disease states; drug-drug interactions; drug-laboratory test interactions; and clinical drug judgment. Clinical pharmacists in psychiatric practice and psychiatrists had the highest scores, and the scores of these two groups were significantly higher than those of the other groups. Nurses practicing in nonmental health institutions had the lowest scores. The results suggested that clinical pharmacists trained in psychotropic drug therapy may be competent to manage this therapy of patients in mental health institutions. Patients receiving this therapy in nonpsychiatric facilities and in ambulatory environments are being served by physicians, nurses and pharmacists whose knowledge of psychotropic drug therapy may be inadequate.
