Treating measles: the appropriateness of admission to a Wisconsin children's hospital.

OBJECTIVE

A large number of children with measles were hospitalized at a children's hospital during a metropolitan measles outbreak. In this study we addressed the appropriateness of those admissions.

METHODS

Charts of all 634 patients with a diagnosis of measles who were treated between August 1989 and April 1990 were reviewed. Determination of the appropriateness of hospital admission was based on severity of illness and presence of severe complications of measles.

RESULTS

Of 564 patients with clinical measles or serologic evidence of recent infection, 252 were inpatients (median age 1.5 years) and 312 were outpatients (median age 2.1 years). Fifty-nine (23.4%) of the inpatients had been inappropriately admitted. Inpatients were significantly more likely than outpatients to have physiologic instability or a clinical complication. Children 15 months of age or younger were more likely to be hospitalized, as were children evaluated in the first 3 months of the outbreak period, even if admission was not appropriate on the basis of physiologic instability or complications.

CONCLUSIONS

Younger patients with measles and patients evaluated earlier in the epidemic were more likely to be admitted to the hospital even when admission was inappropriate as assessed by degree of physiologic instability or presence of complications.
