Recent reports have emphasized the need to reduce the amount of unsupe
rvised surgery performed at night by junior doctors. However there is
little guidance about when an operation must be performed urgently and
when it can be postponed safely. This study describes the existing pa
ttern of out-of-hours trauma and orthopaedic surgery in four hospitals
and reports the views of a panel of surgeons and anaesthetists on the
extent to which operating could be postponed until the following day.
Operations at night are uncommon - a mean of 0.6 per night and occurr
ing on only 40% of nights - though their frequency shows two-fold vari
ation between hospitals. With certain assumptions it is estimated that
up to a third of out-of-hours operations could be postponed safely to
the following day. Further evaluation is required of those operations
about which the panel failed to reach agreement. While most of the pr
ocedures undertaken at night are within the competence of a registrar,
some require the direct involvement of a consultant.
