Tissue transplantation is an important adjunct to modern medical care and is used daily to save or improve patient lives. Tissue allografts include bone, tendon, corneas, heart valves and others. Increasing utilization may lead to tissue shortages, and tissue procurement organizations continue to explore ways to expand the cadaveric donor pool. Currently more than half of all deaths occur outside the acute care setting.

Many who suffer prehospital deaths might be eligible for non-organ tissue donation.

A retrospective review of electronic prehospital medical records was conducted from May 1, 2008 through December 31, 2009. All prehospital deaths were included irrespective of cause. Once identified, additional medical history was obtained from prehospital, inpatient, and emergency department records. Age, medical history, and time of death were compared to exclusion criteria for four tissue procurement organizations (MTF, LifeNet, LifeCell, EyeBank). After analysis, percentages of eligible donors were calculated.

Over 50,000 prehospital records were reviewed; 432 subjects died in the field and were eligible for analysis. Ages ranged from four to 103 years of age; the average was 68.3 (SD = 20.1) years. After exclusion for age, medical conditions, and time of death, 185 unique patients (42.8%) were eligible for donation to at least one of the four tissue procurement organizations (range 11.6%-34.3%).

After prehospital death, many individuals may be eligible for tissue donation. These findings suggest that future prospective studies exploring tissue donation after prehospital death are indicated. These studies should aim to clarify eligibility criteria, create protocols and infrastructure, and explore the ethical implications of expanding tissue donation to include this population.

Despite their popularity and unique characteristics, county shows, also known as agricultural fairs, are amongst the least-studied mass-gathering events. Suffolk Show is one of the biggest such events in the UK, attracting tens of thousands of people annually over a 2-day period. In addition to trade stands and livestock displays, the 2011 show included top international show jumping and other sport activities.

Due to the range of activities and large number of attendees of different ages and medical backgrounds, combined with a lack of objective data about medical contacts made during these events, medical officers and local emergency services find planning an appropriate level of medical coverage for county shows particularly challenging. This study involved analyzing the characteristics of medical contacts during a major county show and assessing the level of medical coverage provided.

Data collected from St John Ambulance (SJA) and British Red Cross standard medical records of all contacts on the show ground over the two days were analyzed in terms of demographics, presenting complaints, medical history, and discharge destination. The Event Safety Guide by the Health and Safety Executive (HSE) was the agreed standard for the level of medical coverage.

More than 90,000 people visited the show, with a total of 180 medical contacts recorded. Patient presentation rate (per 1,000 attendees) was 2.0 and the transport to hospital rate (per 1,000 attendees) was 0.1.

Of the 112 cases handled by SJA, 74 (66%) were women and 49 (44%) were 18-64 years of age. Wounds, lacerations and abrasions made up 26 (23.2%) of all presentations to SJA, followed by foot and lower limb blisters at 20 (17.8%). Hypertension was the most common medical history in presentations to SJA (11 cases, 10%), followed by asthma in 7 (6%).

The majority of presentations were due to minor injuries or ailments. An understanding of the event characteristics, demographics, and nature of medical contacts will provide organizers, medical officers, and local emergency services with information about the level of coverage and resources required. This data can further help advance knowledge of mass-gathering medicine across the various types of events.
