Divers Alert Network (DAN) is a group of not-for-profit organizations dedicated to improving diving safety for all divers. It was founded in Durham, North Carolina, United States, in 1980 at Duke University providing 24/7 telephonic hot-line diving medical assistance. Since then the organization has expanded globally and now has independent regional organizations in North America, Europe, Japan, Asia-Pacific and Southern Africa.
The DAN group of organizations provide similar services, some only to members, and others to any person on request. Member services usually include a diving accident hot-line, and diving accident and travel insurance. Services to the general public usually include diving medical advice and training in first aid for diving accidents. DAN America and DAN Europe maintain databases on diving accidents, treatment and fatalities, and crowd-sourced databases on dive profiles uploaded by volunteers which are used for ongoing research programmes. They publish research results and collaborate with other organizations on projects of common interest.




Function


DAN has an international network of emergency call centers which operate 24 hours a day to provide members with specialized assistance for diving emergencies from a group of experts in Diving and Hyperbaric Medicine




History


In 1977, Undersea Medical Society (later the Undersea and Hyperbaric Medical Society) introduced the concept of a national organization (to replace LEO-FAST at Brooks Air Force Base, directed by Colonel Jefferson Davis, M.D.) where a diving medicine specialist could be contacted by telephone 24 hours a day. Dr. Peter B. Bennett received a two-year grant from National Oceanic and Atmospheric Administration (NOAA) and National Institute for Occupational Safety and Health (NIOSH) in September 1980 to form the "National Diving Accident Network" at the Frank G. Hall Hyperbaric Center at Duke University Medical Center in Durham, North Carolina.
In 1981, DAN published its "Underwater Diving Accident Manual". The Hyperbaric Center received 305 calls for information and assistance. DAN implemented a medical/safety advisory telephone line to handle questions from recreational divers with non-emergency questions in 1982. This change was followed by a name change from "Diving Accident Network" to "Divers Alert Network" and hosted the first annual Diving Accident and Hyperbaric Treatment continuing medical education course at the Duke University Medical Center.
In 1983 International Diving Assistance (IDA), later to become DAN Europe, was founded by dr. Alessandro Marroni as a 24-hour per day diving emergency assistance service, set up as a membership organization, with specific insurance benefits since the start.
In 1984, federal grant monies were decreased (50 percent in 1982 and then by 25 percent in 1983) and support now comes exclusively from divers and the diving industry.
In 1985 DAN started a 'sponsor program' for clubs, stores and corporations,
In 1987 the Civil Alert Network (CAN) began assisting diving emergencies in Japan, under the guidance of prof. Yoshihiro Mano of the University of Tokyo Medical School. This would become DAN Japan. Also in 1987, DAN started the first dive accident insurance program for members. After the introduction of this program the membership numbers doubled to 32,000 in 1988.
The IRS granted DAN its 501(c)(3) non-profit status in 1990. The organization continues to be associated with Duke University Medical Center, but moved its offices from the Frank G. Hall Labs to off campus office space. In 1991 DAN introduced its first training course 'Oxygen First aid Training Program' and DAN Travel Assist. In the same year the 'Flying After Diving' research trials began.
The need for an international organisation that would be available to all divers, wherever they dived around the world, became increasingly apparent and, during a meeting at DAN Headquarters in Durham, N.C., US, in February 1991, the process to form an International DAN was started. The four existing organisations decided to adopt the common name of DAN. and International DAN – also known as IDAN – was established to support the regional IDAN members - DAN America, DAN Europe, DAN Japan, and DAN Asia-Pacific.
In 1992 Emergency medical evacuation, was added as a member benefit, and DAN was awarded the Undersea and Hyperbaric Medical Society's Craig Hoffman Diving Safety Award in June of that year for its significant contributions to the health and safety of recreational divers. In September the first DAN Instructor Training Workshop was held, and the Oxygen First Aid Training program was introduced to Europe.
1993 saw DAN open an insurance company 'Accident General Insurance'.
Dan Asia Pacific was founded in 1994 under the name DAN Australia by Australian diver, John Lippmann OAM, after dual approaches from DAN America and Dr John Williamson of the Australian Diver Emergency Service (DES) to "establish a DAN entity in the Asia-Pacific."
DAN Southern Africa joined the IDAN in 1996 with Frans Cronjé, M.D. as CEO By 1996 Oxygen First Aid Training was being taught in seven continents.
DAN introduced other diving related first aid training courses – 'Oxygen first aid for aquatic emergencies' (1998), 'Remote Oxygen (REMO2) (1999), Hazardous Marine Life Injuries (2000), Automatic External Difibrillation (AED) (2001) and Advanced Oxygen Provider (2002). DAN moved to its new, permanent headquarters, the Peter B. Bennett Center.
Dr. Bennett received the 2002 Diving Equipment and Marketing Association Reaching Out Award for his contribution to the dive industry and the Carolinas' Ernst and Young Entrepreneur of the Year 2002 award for contributions to business in the life sciences. He announced his retirement as DAN President effective June 30, 2003 After Bennett resigned as DAN President and CEO, DAN Executive Vice President and Chief Operating Officer Dan Orr, MS was named acting president and CEO. DAN established the Peter B. Bennett Research Fund, within the Endowment Fund to support research initiatives, enhancing dive safety into the future.
In 2004, Michael D. Curley, Ph.D. was named DAN America President and CEO. In 2006, Dr. Curley stepped down and Mr. Orr was named as the DAN President and CEO. In February 2009, DAN launched a web site for their bi-monthly magazine "Alert Diver Online".
DAN reported membership numbers worldwide for 2019 as: DAN US/Canada, 274,708; DAN Europe, 123,680; DAN Japan, 18,137; DAN World Asia Pacific, 12,163; DAN World Latin America/Brazil, 8,008; DAN Southern Africa, 5,894.

Medical hotline

DAN Europe provides its members with medical assistance in case of a diving emergency, 24/7 and from anywhere in the world. There is an international line for use when the member is abroad, and each country has a national emergency number.

When the emergency is in the diver's country of residence, the national hotline is used and the case is managed locally from the national center, according to Standard DAN Europe protocol.
When the emergency occurs outside of the diver's country of residence. the central DAN Europe hotline is used. A diver who calls from abroad is normally put into contact with a DAN specialist of the same language as the victim, so that the case may be evaluated without language difficulties.
If the accident occurred in an area where a national DAN centre exists, the local centre will manage the emergency in coordination with the Rome centre and the specialist from the victim's home country.
If the accident occurred in a country without a national DAN centre, the intervention will be managed directly by the central DAN Europe hotline.

Research






= Completed programs

=
Flying After Recompression Treatment Study. Online survey of divers in 2003 who were recompressed for decompression illness within the previous five years and then flew in an airplane. The study was published in the Management of Mild or Marginal Decompression Illness in Remote Locations Workshop Proceedings.
Diabetes & Diving. Two studies were made on recreational diving by persons with diabetes who showed good general blood glucose control prior to entry to the study. The first followed adults with diabetes who were previously certified to dive and the second studied teenagers with diabetes immediately following their certification training.
US Navy Survey. DAN conducted a survey of recreational divers to obtain information about diver demographics, dive experience and diving habits on behalf of the US Navy in early 1998.
Live-aboard Doppler. Researchers assessed the effects of age, gender and dive profiles on post-dive vascular bubble presence in volunteer participants during 1988/9 using Doppler monitoring devices.
Aging Diver Study. Preliminary evaluation of the effects of age and associated medical conditions on dive style and dive outcome using PDE methodology.
Breath-Hold Study. The effects of hyperventilation, work, breathing mixture and dive depth on immersed breath-hold duration were investigated to allow an increase in breath-hold time to a maximum safe level without excessive risk of loss of consciousness or functional incapacity due to hypocapnia, hypoxia or hypercapnia.
Flying After Diving. DAN conducted human trials from 1993 to 1999 to investigate how long to wait after diving before flying for recreational divers with support from the US Navy.
First Aid Oxygen Rebreather. Performance studies made on first- and second-generation closed-circuit oxygen rebreathing circuits developed for remote duty first aid applications confirmed effective performance in the second-generation device.
Cialis™/Viagra™ and the Risk of Oxygen Toxicity. A rat model produced positive results of increased risk of oxygen toxicity risk using these drugs.




= Ongoing programs

=
Flying After Diving Calibration Study. To find out how exercise affects the minimum safe waiting period before flying after diving.
Risk/Benefit of PFO Closure. To find out if divers with PFO who underwent the closure procedure are better off than divers with PFO who continue diving without the closure.
Sudafed and Risk of Oxygen Toxicity. This study uses an animal model to find out whether Sudafed increases the risk of oxygen toxicity.
Extreme Diving Field Study. To analyse aspects of safety including decompression safety, physical fitness requirements and cardiovascular effects of extreme diving.
Incidents and Accidents in Compressed Air Diving. DAN compiles case reports of diving incidents, injuries and fatalities in air, nitrox and mixed-gas diving and includes data from these reports in the DAN Annual Diving Report.
Incidents and Accidents in Breath-Hold Diving. Both fatal and nonfatal cases are collected to identify risks and aid in public education. Data from case reports is included in the DAN Annual Diving Report.
Project Dive Exploration (PDE). Dive profiles, diver characteristics and diver behaviour are uploaded by volunteers using the dive computer's dive log software and recorded for statistically accurate analysis. This is a prospective observational study of the demographics, medical history, depth-time exposure and medical outcome of a sample of the recreational diving population, with the intention of finding the incidence of decompression sickness in population subgroups and the relationship of DCS probability to depth-time profile and dive and diver characteristics. The data also provides an injury-free control population for comparison with DAN's injury and fatality data to identify possible risk factors associated with injury and death. The results of this study are likely to be useful in the development of future decompression models. Divers using one of many compatible dive computers may contribute their electronic dive log data to PDE.
DAN Membership Health Survey (DMHS). To establish the prevalence of cardiovascular risk factors, diabetes and asthma, access to primary health care and the diving practices of DAN Members to help the diving community decide on preventive measures for injuries and fatalities.
Database of Dive Exposure and Dive Outcomes. Data from the US Navy, Duke University, PDE, DAN Europe's Dive Safety Lab and the Institute of Nautical Archaeology are converted to a format which can be used as a reference database for calibration and evaluation of decompression algorithms.
Diver Physical Fitness Study. Physical fitness of divers and the physical fitness required for typical diving activities will be assessed.
Fatality Database. DAN collects data on diving fatalities of recreational divers in the US, Canada and diving destinations frequented by US and Canadian divers, compiles case reports, and includes the data in the DAN Annual Diving Report.




= Publications

=

DAN publishes research results on a wide range of matters relating to diving safety and medicine and diving accident analysis, including annual reports on decompression illness and diving fatalities. Many are freely available on the internet.
The magazine "Alert Diver" is published by some of the regional branches, including the US, Europe, and Southern Africa, in paper and electronic formats. Although the different publications may occasionally reprint material from each other, they generally contain different content. Article topics generally include diving physiology, medicine, safety, and diving destinations.




Conferences






= Rebreather Forum 3

=
In May 2012, DAN along with the American Academy of Underwater Sciences and the Professional Association of Diving Instructors hosted the Rebreather Forum 3 (RF3) which was organised by Rosemary E Lunn. This three-day safety symposium was convened to address major issues surrounding rebreather technology, and its application in commercial, media, military, scientific, recreational and technical diving. Experts, manufactures, instructor trainers, training agencies and divers from all over the world discussed this technology and shared information. Associate Professor Simon J Mitchell chaired the final session at RF3 and, as a result, 16 key consensus statements were agreed and ratified by the global rebreather community.
