Clinical pharmacy in disease-specific clinics.

The literature that describes and evaluates clinical pharmacy services in disease-specific clinics is briefly reviewed. Various evaluation techniques are discussed, highlighting examples of sites using these techniques in published studies. The evaluation of clinical pharmacy services has evolved from examining a single parameter such as disease outcome to examining the broader perspective of the value of clinical pharmacists in the health care system, taking into account structure and process as well as outcomes. Assessment tools should consider all of these aspects to satisfactorily evaluate the value of clinical pharmacists in clinics.
