Sufficient knowledge required to deal with emergencies at the accident site may not be found in most medical students due to the lack of effective first-aid training in most medical education curricula. This study aims to assess and evaluate medical students’ knowledge level in providing first-aid care, especially first-year students.

An electronic questionnaire was distributed via social media to 1,855 medical students in October 2020. The knowledge level was assessed based on scores obtained for each clinical scenario requiring first aid and classified as good, intermediate, or weak. Statistical analysis was performed using SPSS software.

The study found that academic year and specialization significantly influence medical students’ first-aid knowledge level. However, demographic factors such as gender, university, marital status, housing status, work status, financial condition, and previous first-aid training did not show any significant effect.

The level of knowledge among Syrian medical students in providing first-aid care is somewhat limited. Therefore, first-aid courses should be made more accessible to these students, and their effectiveness should be ensured and maintained through frequent updates. Moreover, more attention should be placed on publicizing first-aid knowledge to make life-saving procedures attainable to anyone, anytime and anywhere.

After officer-involved shootings (OIS), rapid delivery of emergency medical care is critical but may be delayed due to scene safety concerns. The purpose of this study was to describe medical care rendered by law enforcement officers (LEOs) after lethal force incidents.

Retrospective analysis of open-source video footage of OIS occurring from February 15, 2013 through December 31, 2020. Frequency and nature of care provided, time until LEO and Emergency Medical Services (EMS) care, and mortality outcomes were evaluated. The study was deemed exempt by the Mayo Clinic Institutional Review Board.

Three hundred forty-two (342) videos were included in the final analysis; LEOs rendered care in 172 (50.3%) incidents. Average elapsed time from time-of-injury (TOI) to LEO-provided care was 155.8 (SD = 198.8) seconds. Hemorrhage control was the most common intervention performed. An average of 214.2 seconds elapsed between LEO care and EMS arrival. No mortality difference was identified between LEO versus EMS care (P = .1631). Subjects with truncal wounds were more likely to die than those with extremity wounds (P < .00001).

It was found that LEOs rendered medical care in one-half of all OIS incidents, initiating care on average 3.5 minutes prior to EMS arrival. Although no significant mortality difference was noted for LEO versus EMS care, this finding must be interpreted cautiously, as specific interventions, such as extremity hemorrhage control, may have impacted select patients. Future studies are needed to determine optimal LEO care for these patients.

St John Ambulance Operations Branch Volunteers have been providing first-aid services at the Royal Adelaide Show for 90 years. The project arose from a need to more accurately predict the workload for first-aid providers at mass gathering events. A formal analysis of workload patterns and the determinants of workload had not been performed.

Casualty presentation workload would be predicted by factors including day of the week, weather, and crowd size.

Collated and analyzed casualty reports over a seven-year period representing >7,000 patients who presented for first-aid assistance for that period (63 show days) were reviewed retrospectively.

Casualty presentations correlated significantly with crowd size, maximum daily temperature, humidity, and day of the week. Patient presentation rate had heterogeneous determinants. The most frequent presentation was minor medical problems with Wednesdays attracting higher casualty presentations and more major medical categories.

Individual event analysis is a useful mechanism to assist in determining resource allocation at mass gathering events providing an evidence base upon which to make decisions about future needs. Subsequent analysis of other events will assist in supporting accurate predictor models.

Rock and contemporary music concerts are popular, recurrent events requiring on-site medical staffing.

To describe a novel severity score used to stratify the level of acuity of patients presenting to first-aid stations at these events.

Retrospective review of charts generated at the first-aid stations of five major rock concerts within a 60,000 spectator capacity, outdoor, professional sports stadium. Participants included all concert patrons presenting to the stadiums first-aid stations as patients. Data were collected on patient demographics, history of drug or ethanol usage while at the concert event, first-aid station time, treatment rendered, diagnosis, and disposition. All patients evaluated were retrospectively assigned a “DRUG-ROCK” Injury Severity Score (DRISS) to stratify their level of acuity. Individual concert events and patient dispositions were compared statistically using chi-square, Fisher's exact, and the ANOVA Mean tests.

Approximately 250,000 spectators attended the five concert events. First-aid stations evaluated 308 patients (utilization rate of 1.2 per 1,000 patrons). The most common diagnosis was minor trauma (130; 42%), followed in frequency by ethanol/illicit drug intoxication (98; 32%). The average time in the first-aid station was 23.5±22.5 minutes (± standard deviation; range: 5–150 minutes). Disposition of patients included 100 (32.5%) who were treated and released; 98 (32%) were transported by paramedics to emergency departments (EDs); and 110 (35.5%) signed-out against medical advise (AMA), refusing transport. The mean DRISS was 4.1 (±2.65). Two-thirds (67%) of the study population were ranked as mild by DRISS criteria (score = 1–4), with 27% rated as moderate (score = 5–9), and 6% severe (score >10). The average of severity scores was highest (6.5) for patients transported to hospitals, and statistically different from the scores of the average of the treated and released and AMA groups (p <0.005).

The DRISS was useful in stratifying the acuity level of this patient population. This severity score may serve as a potential triage mechanism for future mass gatherings such as rock concerts.

Evaluate the experience of paramedic personnel at mass gatherings in the absence of on-site physicians.

Retrospective review of patients evaluated by paramedics with emergency medical services (EMS) medical control.

First-aid facility operated by paramedics at an outdoor amphitheater involving 32 (predominantly rock music) concerts in accordance with the Chicago EMS System, June through September 1990.

A total of 438 patients (≤0.1% on-site population) were evaluated.

Presentations to the first-aid facility were viewed as if the patient was presenting to an ambulance. Transportation to an emergency department was strongly recommended for all encounters. Time from presentation to the first-aid facility until disposition was limited to 30 minutes in the absence of on-line [direct] medical control. Refusal of care was accepted. On-line [direct] medical control with the EMS resource hospital was initiated as needed. Off-line [indirect] medical control consisted of weekly reviews of all patient records and periodic site visits.

Of the 438 patients, 366 (84%) refused further care, including 31 patients (7%) who refused advanced life support (ALS) level care. Seventy-two patients (16%) were transported; 37 by ALS and 35 by basic life support (BLS) units. On-line [direct] medical control was initiated in all ALS patients that were transported as well as for those who refused care. No known deaths or adverse outcomes occurred, based on lack of inquiries or complaints from the local EMS system, emergency departments receiving transported patients, law enforcement agencies, 9-1-1 emergency response providers, venue management, or security. No request for medical records from law firms have occurred. Problems noted initially were poor documentation and a tendency not to document all encounters (e.g., dispensing band-aids, tampons, earplugs, etc.). Concerns noted included: initial and subsequent vital signs, times of arrival, interventions, dispositions, and patient conditions of refusal. Specific problems with documentation of refusals at disposition included: appropriate mental status, speech, and gait; release with an accompanying family member or friend; and parental notification and approval of care for minors. There also was an initial tendency not to establish on-line [direct] medical control for ALS refusal or BLS medicolegal issues.

The medical system configuration modeled after practices of prehospital care, demonstrates physicians did not need to be onsite when adequate EMS medical control existed with less than 30 minutes on-scene time.
