Abstract
Objective: The problem severity of patients seen by a psychiatric consultationliaison service was studied through the use of a routine outcome measure.
Methods: Ratings on the Health of the Nation Outcome Scales (HoNOS) over nearly 3 years in the emergency department, general hospital, and on admission to the acute psychiatric unit were compared.
Results: Mean HoNOS total scores in the emergency department were not significantly different from those at admission to the acute psychiatric unit, but were significantly higher than those in the general hospital. Mean scores in all three settings were higher than those obtained at case review of psychiatric patients in the community. Despite differences in age, sex, and psychiatric diagnosis between the three hospital settings, differences in mean HoNOS total scores remained substantially unchanged after adjustment for these factors. Most HoNOS assessments were performed by medical staff.
Conclusions: The suspected high levels of problem severity and comorbidity of patients seen by a psychiatric consultation-liaison service were confirmed through the use of a routine outcome measure.
