    Use of collaborative request model was highly correlated with organ donation consent.

    Background: There continues to be a disconnect between Australian’s self-reported support for organ donation and formal end-of-life family consent rates. In 2015, a multi-site Australian study by Lewis et al. demonstrated that consent rates were optimised by involving a clinician who had specific training in donation conversations, and in addition, was independent of the treating team. This approach is known as “Collaborative requesting” in Australia. The aim of the study was to report our single institution’s experience in introducing and augmenting the collaborative request model. Methods: The Royal Melbourne Hospital (RMH), is one of two adult tertiary trauma centres for the city of Melbourne, Australia. Additionally, the hospital has specialist neurosurgical and stroke services. Australia permits organ donation via both brain death and controlled circulatory death pathways. The hospital co-employs 4 embedded Donation Specialist Nursing Coordinators, and 3 fractionally appointed Medical Donation Specialists. Both craft groups have specialist communication training, and in addition, nursing coordinators have detailed end-to-end case donation management experience. Over a three-year period, the RMH progressively implemented the request model. Rather than using “any” independent clinician with donation communication training (the Lewis Model), the unit promoted the use of embedded Donation Specialist Nursing Coordinators as the collaborative requestors (the augmented collaborative model). Results: From January 2016 to June 2018 there were 135 donation requests raised by staff. Donation conversations raised by the family were excluded from analysis, as they have a consent rate at our hospital of over 90%. During the study period collaborative requesting increased from 50% (Jan 2016) to 96% (Jun 2018). Over the 3 study years (2016, 2017 and first half of 2018), the consent rate was highly positively correlated with the increased use of a collaborative model (r2=0.984). Conclusions: Since the introduction of embedded donation specialist nursing coordinators in RMH ICU, the hospital has seen both a clinically and statistically significant improvement in organ donation consent rates.

    Laboratory-derived early warning score for the prediction of in-hospital mortality, intensive care unit admission, medical emergency team activation and cardiac arrest in general medical wards
    Ratnayake, H ; Johnson, D ; Martensson, J ; Lam, Q ; Bellomo, R (WILEY, 2021-05)
    BACKGROUND: General medical wards admit a varied cohort of patients from the emergency department, some of whom deteriorate during their hospital stay. Currently, we use vital signs based warning scores to predict patients at risk of imminent deterioration, but there is now a growing body of literature that commonly available laboratory results may also help to identify those at risk. AIM: To assess whether a laboratory-based admission score can predict in hospital mortality, intensive care unit (ICU) admission, medical emergency team (MET) activation or cardiac arrest in a cohort of Australian general medical patients admitted through the emergency department (ED). METHODS: We performed a retrospective observational study of all general medical admissions to hospital through the ED in 2015. Admission pathology was used to calculate a risk score. In-patient outcomes of death, ICU transfer, MET call activation or cardiac arrest were collected from hospital records. RESULTS: We studied 2942 admissions derived from 2521 patients, with a median age of 81 years. There were 143 in-patient deaths, 82 ICU admissions, 277 MET calls and 14 cardiac arrest calls. The laboratory-based admission score had an area under the receiver operating characteristic curve (AUC-ROC) of 0.76 (95% confidence interval (CI): 0.72-0.80) for inpatient death, an AUC-ROC of 0.79 (95% CI: 0.66-0.93) for inpatient cardiac arrest, an AUC-ROC of 0.64 (95% CI: 0.58-0.70) for ICU transfer and an AUC-ROC of 0.59 (95% CI: 0.55-0.62) for MET call activation. When patients aged over 75 were analysed separately, the AUC-ROC for prediction of in-patient death was 0.74 (95% CI: 0.70-0.78) and increased to 0.86 (95% CI: 0.73-0.98) for the prediction of in-patient cardiac arrest. CONCLUSION: A simple laboratory-derived score obtained at patient admission is a fair to good predictor of subsequent in-patient death or cardiac arrest in general medical patients and in the older patient cohort. Prospective interventional studies are required to ascertain the clinical utility of this admission score.
