Emergency Departments are experiencing an ever increasing volume of patients presenting for medical care. At times, the number of patients in Emergency Departments can exceed the number of available beds. When this happens, sicker patients are allocated to treatment areas while those less unwell are required to wait in the waiting room. Some waiting room patients will inevitably become more unwell before being seen by a doctor. Measuring vital signs - blood pressure, heart rate, breathing rate, blood oxygen levels, temperature - is a proven method for early detection of deterioration in unwell patients. Emergency triage clinicians endeavour to measure vital signs of waiting room patients, however, their ability is significantly limited during period of insufficient staffing and overcrowded waiting rooms. Innovative, camera-based advanced sensor technology could facilitate automatic, contactless, vital sign measurement during periods where available resources are limited or overwhelmed. Contactless vital sign measurement could thus enable early detection of patient deterioration and improve patient safety in emergency department waiting rooms. Such technology has shown promise in recent studies but has not been rigorously tested in an Australian Emergency Department. This project will study one such technology to determine its reliability and accuracy in measuring vital signs in waiting room patients at Townsville University Hospital Emergency Department. If this technology is found to be reliable and accurate, this study will improve quality of care and safety for patients in emergency department waiting rooms.
READ MOREThe objective of this research was to evaluate the effect of working consecutive night shifts on sleep time, prior wakefulness, perceived levels of fatigue and psychomotor performance in a group of Australian emergency registrars. A prospective observational study with a repeated within-subjects component was conducted. Sleep time was determined using sleep diaries and activity monitors. Subjective fatigue levels and reciprocal reaction times were evaluated before and after day and night shifts.
