Abstract: The authors conduct an audit of medical activity at Christchurch Hospital, a 650 bed tertiary centre, between 2230 and 0800 hours. They measured the volumes of tasks requiring completion overnight and identified the competencies required for this as well as the level of teamwork that existed. They found several organisational areas of concern, that indicate new approaches are required to staff the “hospital at night,” and an Out of Hours Multidisciplinary Team is recommended. Specific issues included the lack of teamwork from the Resident Medical Officers (RMOs), with some overextended while others were inactive. House officer tasks were largely generic rather than specialty specific; there was no formal handover from the afternoon or day shifts and the level of hospital medical staffing did not reflect the activity levels over the time period studied. The researchers also recommend an urgent review of the beep policy. A third of the admissions were to General Medicine, and basic medical activities (including admitting, reviewing, and prescribing drugs and fluids) for patients admitted under all specialties represented the majority of the night workload. Medical registrars had reduced some of the traditional multiple clerking by admitting patients themselves.
