Using national data to model the New Zealand radiation oncology workforce.

INTRODUCTION: Demand for radiation therapy is expected to increase over time. In Aotearoa/New Zealand, the radiation oncology workforce experiences high numbers of clinical hours but an intervention rate that is lower than in comparable countries, suggesting unmet treatment need. Accurate models on the supply and demand for radiation oncologists (ROs) are needed to ensure adequate staffing levels. METHODS: We developed a demand model that predicted the future number of ROs required, using national data from the Radiation Oncology Collection (ROC) and a survey of ROs. Radiation therapy intervention and retreatment rates (IR/RTRs), and benign and non-cancer conditions being treated, were derived from the ROC and applied to Census population projections. Survey data provided definitions of treatment by complexity, time spent in different activities and time available for work. Results were linked to radiation oncology workforce forecasts from a supply model developed by the Ministry of Health. RESULTS: The demand model showed that 85 ROs would be needed in 2031, if current IR/RTRs were maintained, an increase from 68 in 2021. The supply model predicted a decrease in ROs over time, leaving a significant shortfall. Model parameters could be modified to assess the impact of workforce or practice changes; more ROs would be needed if average working hours reduced or IR/RTRs increased. CONCLUSION: Workforce models based on robust data collections are an important tool for workforce planning. The RO demand model presented here combines detailed information on treatment and work activities to provide credible estimates that can be used to inform actions on training, recruitment and retention.

Accuracy of pre-hospital trauma notification calls.

STUDY OBJECTIVE: The aim of this study is to determine the accuracy of pre-hospital trauma notifications and the effects of inaccurate information on trauma triage. METHODS: This study was conducted at a level-1 trauma center over a two-year period. Data was collected from pre-notification forms on trauma activations that arrived to the emergency department via ambulance. Trauma activations with pre-notification were compared to those without notification and pre-notification forms were assessed for accuracy and completeness. RESULTS: A total of 2186 trauma activations were included in the study, 1572 (71.9%) had pre-notifications, 614 (28.1%) did not and were initially under-triaged. Pre-notification forms were completed for 1505 (95.7%) patients, of which EMS provided incomplete/inaccurate information for 1204 (80%) patients and complete/accurate information for 301 (20%) patients. Missing GCS/AVPU score (1099, 91.3%), wrong age (357, 29.6%), and missing vitals (303, 25.2%) were the main problems. Missing/wrong information resulted in trauma tier over-activation in 25 (2.1%) patients and under-activation in 20 (1.7%) patients. Under-triaged patients were predominantly male (18, 90%), sustained a fall (9, 45%), transported by BLS EMS teams (12, 60%), and arrived on a weekday (13, 65%) during the time period of 11 pm-7 am (9, 45%). A total of 13 (65%) required emergent intubation, 2 (10%) required massive transfusion activation, 7 (35%) were admitted to ICU, 3 (15%) were admitted directly to the OR, and 1 (15%) died. CONCLUSION: EMS crews frequently provide inaccurate pre-hospital information or do not provide any pre-hospital notification at all, which results in over/under triage of trauma patients.

Contrast echocardiography: experience in a clinical echocardiography laboratory.

Although 2-dimensional echocardiography with adjunct intravenous contrast media improves endocardial visualization and enhances quality of spectral Doppler signals, widespread use of contrast agents has not occurred for various reasons. Results from this study indicate that discretionary use of contrast media will enhance endocardial and Doppler signal visualization scores without an impact on total procedure duration, lending credence to an argument for a lower threshold for discretionary use of contrast media.
