To discover whether general practitioners are correctly notified of a patie
nt's final diagnosis following hospital discharge, an observational study w
as undertaken in a district general hospital. The final diagnosis was compa
red with the diagnosis documented in the discharge summary and the take-hom
e prescription. Two hundred discharges were studied. Only 163 (81%) dischar
ge summaries and 138 (69%) take-home prescriptions had the correct diagnosi
s; 24 (12%) take-home prescriptions did not have any diagnosis at all. In s
ome cases the diagnosis differed between the discharge summaries and the ta
ke-home prescriptions. Only in 122 (61%) cases was the final diagnosis corr
ectly documented in both instances. Communication regarding diagnosis in di
scharge letters is less than adequate. Every effort should be made to impro
ve this.
