Background. Inappropriate use of hospital services, in the form of unj
ustified hospital stay days (HSD), constitutes a major burden on a hea
lth budget. Reduction of unjustified HSD was achieved in a medical war
d in a previous intervention study. Methods. A controlled intervention
aimed at reducing unjustified hospital stay was performed on 155 paed
iatric inpatients and 248 controls, by applying pre-set criteria for h
ospitalization and comparing to results in previous studies.Results, U
njustified stay was decreased from 32.6% to 14.8% on the study ward, a
nd from 25.7% to 19.3% on the control ward. The children on both wards
did not differ significantly in rates of subsequent out of hospital m
ortality, re-admission, and the subjective evaluation of health by the
ir parents one month following discharge. Conclusions. This study demo
nstrates that despite the fact that the per cent of unjustified HSD on
a paediatric ward is much lower than on medicine or surgery, a signif
icant reduction in unjustified stay can be achieved by intervention pr
ogramme.
