Delta Shock Index in Predicting Massive Transfusion

Taiwan7,957 participantsStarted 2018-06-05

Plain-language summary

Background: To determine the performance of delta shock index (ΔSI), a change in shock index (SI) upon arrival at the emergency room (ER) from that in the field in predicting the need for massive transfusion (MT) among adult trauma patients with stable blood pressure. Methods: This study included data from all trauma patients aged 20 years and above who were hospitalized from January 1, 2009 to December 31, 2016 and was obtained from the registered trauma database of the hospital. Only patients who were transferred by emergency medical service from the accident site with a systolic blood pressure ≥ 90 mm Hg at the ER were included in this study. The 7,957 enrolled trauma patients were divided into 2 groups, those who had received blood transfusion ≥ 10 U (MT, n = 82) and those who had not (non-MT, n = 7,875). The odds ratios with 95% confidence intervals for associated patient conditions and the odds of need for MT by a given ΔSI were measured. The plot of specific receiver operating characteristic (ROC) curves was used to evaluate the best cutoff point that could predict the patient's probability of receiving MT.

Inclusion Criteria: * Patients who were transferred by emergency medical service (EMS) from the field of accident and had a stable blood pressure (SBP ≥ 90 mmHg) at the ER were included Exclusion Criteria: * Patients who were transferred from other hospitals or arrived by private vehicles. * Patients who had incomplete data * Patients who had an unstable blood pressure (SBP \< 90 mmHg) upon arrival at the ER were also excluded

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
