Brief Summary:
The goal of this observational study is to develop a decision support system in patients presenting with chest pain in the prehospital setting The main question it aims to answer is
Performance of a machine learning based model for decision support of patients in contact with emergency medical services due to chest pain
Participants will be asked to
respond to questions asked by the clinician at the scene regarding previous known risk factors and pain characteristics
consent to the collection of routinely available data from medical records
consent of taking one blood sample capillary or venous if perifer catheter is placed for standard care reasons troponin and glucose which is measured at the scene disposed and the result is entered in the clinical report form

Detailed Description:
Prehospital emergency care has undergone dramatic changes in recent decades From the fact that the ambulance nurse has previously started care at the site of the illness with the goal of transporting the patient to the nearest emergency room prehospital care has become increasingly differentiated This means that care at the right level of care has become a watchword and a number of different levels of care have become relevant ranging from fast track and rapid investigation and treatment in hospital for heart attack acute myocardial infarctions and strokes to the patient being left at the scene with advice on self-care
In principle there is three overall levels of care1 Need for inpatient resources2 Need for primary care contact or visit by mobile healthcare team within the next day and 3 Referral to home care provide support for self-care or treatment on site
This places competence requirements on the ambulance nurse with requirements for a prehospital assessed condition compatible with a level of care where the patients needs can be met This approach puts patient safety in focus in a different way than before Because with this procedure patients with time-sensitive conditions such as stroke heart attack acute myocardial infarction and sepsis run an increased risk of being left at the scene with advice on self-care due to inappropriate prehospital assessment In prehospital emergency care the assessment of the severity of the patients condition takes place in two stages 1 At the emergency dispatch centre when the patient has called the national emergency number and 2 At the scene of the illness by the ambulance nurse after arrival at the patients side
The basis for prehospital decision support is a identification of time-sensitive conditions ie conditions where the time to initiation of causal treatment can affect the prognosis and b identification of predictors ie factors that are already prehospitally characteristic of the condition disease or accident itself but also of the severity of the condition The classic examples of time-critical conditions are manifestations of cardiovascular diseases such as heart attack acute myocardial infarction and stroke but also serious infectious diseases such as sepsis and severe trauma Predictors can be identified via measurement of vital parameters such as pulse blood pressure and oxygen saturation medical history previously known diseases and current onset current symptom picture clinical manifestations pallor examination findings ECG and analysis of biochemical markers by capillary blood test glucose troponin
Current studies indicate that for many patients in contact with the emergency medical service due to acute chest pain other options than the emergency department eg follow-up in primary care may be more beneficial for the patient and less resource-intensive for the ambulance and the emergency care In these cases a decision support system based on gender medical history symptoms and clinical observations including ECG and and biochemical markers troponin could provide support for the ambulance nurse Chest pain is one of the most common search causes and constitutes about 10 of assignments in the Swedish emergency medical service
Linked to the assessment in the prehospital environment is patient safety An inappropriate prehospital assessment can compromise patient safety and risk delaying time to treatment Primarily it refers to patients with time-sensitive conditions who are not transported by ambulance directly to hospital after the initial assessment At the same time patient safety can be compromised by transporting frail elderly people to an emergency room where long wait times can increase the risk of complications Transportation of low-risk patients can also increase the risk of crowding in the emergency department and also have a crowding-out effect lack of ambulance availability in case of high priority cases An example of displacement effects is extended response times for the ambulance in the event of sudden unexpected cardiac arrests
Patient safety is poorly studied in the prehospital setting Own experiences indicate that the risk of adverse events in so-called Prio1 assignments highest priority is particularly high and that in about 20 of these assignments the prehospital assessment can be questioned
The goal of the present study is to evaluate and further develop a decision support system developed within the Emergency Medical Service in Region Halland Sweden with collection of variables to validate the previously developed model on unseen data and to further develop a machine learning model for classification The idea is that such decision support should provide support for the ambulance nurse in the assessment of the patient at the scene partly to optimize the possibility of the patient quickly getting to the right level of care and partly to increase patient safety The objective is to only collect data at the scene blood test questionnaire together with routine data from medical records Patients consenting to be part of the study will not receive any other care than standard care according to guidelines which constitutes transport to the emergency department for further examination
