Management of malaria before and after introduction of a treatment protocol at the Eldoret District Hospital.

ABSTRACT

PIP: In Kenya, health professionals compared prospective data on 193 suspected malaria patients at the Eldoret District Hospital during February-March, 1992, with retrospective data on 120 suspected malaria cases at the same hospital during November-December, 1991, to examine the protocol on the management of suspected malaria cases. Between these 2 periods, physicians introduced a simple algorithm to follow in suspected malaria cases. The use of quinine as the 1st choice drug fell considerably between the 2 periods (54.2-19%). There was an increase in the use of chloroquine as the 1st choice drug for uncomplicated malaria (38.4-63.9%). The proportion of blood smear positive patients increased (27.5-51.3%), probably because the department technician was more careful conducting repeat blood smears than were technicians at the busy hospital laboratory. Blood smear negative patients were less likely to automatically receive any antimalarial treatment or quinine in 1992 than in 1991 (14.6% vs. 47.5% and 4.1% vs. 30.9%, respectively). The proportion of patients whose final diagnosis was an illness other than malaria was higher in 1992 than in 1991 (19.7% vs. 15.8%). No clear diagnosis other than flu-like illness was the case for 28 (14.5%) of the prospective patients. The tendency for clinicians to accept a diagnosis of malaria without enough evidence to confirm it can have the damaging effect of masking other serious diagnoses (e.g., dysentery [8 cases], meningitis [6 cases], and HIV infection [2 case]). These findings show that hospital physicians should develop simple protocols for inpatient management of suspected malaria cases, a properly quantified blood smear should be done of all suspected malaria cases to confirm or refute the diagnosis, and chloroquine should be the 1st line of treatment in the Kenyan highlands, until considerable parasite resistance is confirmed.
