Objective: To describe the rate of negative, unexpected and adverse ev
ents associated with hospital-in-the-home (HIH) care in an established
unit, and to validate indicators of safety for HIH care. Design: Pros
pective descriptive survey. Patients and setting: 231 patients, who wo
uld otherwise have required hospitalisation, accepted for acute home-b
ased care by the HIH unit at Frankston Hospital, a 350-bed hospital se
rving a population of 240 000 on the south-eastern boundary of Melbour
ne. Main outcome measures: The following indicators of safety: patient
telephone calls to the on-call service; unscheduled staff callout to
patients' homes; return to hospital during an HIH admission; and retur
n to hospital after discharge. Results: 190 acute admissions were exam
ined. Planned same-day admissions were uneventful and excluded from th
e analysis. The therapies provided were intravenous therapy (mainly an
tibiotics), anticoagulation, and wound care. Unplanned patient telepho
ne calls were received in 6.3% of admissions; 5.8% of acute admissions
required an unscheduled staff home attendance; 4.2% of episodes resul
ted in a return to hospital, of which 2.6% required continued care in
hospital; 2.2% of episodes resulted in a return to hospital within 14
days of discharge for a related problem. The rate of iatrogenic advers
e events was 3.5%. Conclusions: HIH care is very safe. This study may
help define safety standards for HIH care so that future studies can c
ompare them with those of traditional inpatient care.
