Impact of a Half Dome Cable Permitting Process on Search and Rescue Activity, Hiker Mortality Rates, and Operational Costs Above Little Yosemite Valley.

INTRODUCTION: The summit of Yosemite's Half Dome is reached using cable handrails for the final 146 m (480 ft). Access to these cables was restricted to users with permits in 2010. The authors aim to describe the impact of permitting on search and rescue (SAR) in the region of the park most affected by permitting. METHODS: An observational study from 2005 to 2009 and 2011 to 2015 comparing the number of incidents, major incidents (exceeding $500), victims, and fatalities before and after permitting the use of cable handrails on Half Dome in the area above Little Yosemite Valley (LYV) and parkwide. Each year was analyzed separately with t tests and Mann-Whitney U tests. Data are presented as mean±SD. RESULT: The number of hikers in the study area was reduced by up to 66% by permitting. Above LYV from 2005 to 2009, there were 85 SAR incidents, 134 victims, 8 fatalities, 38 major incidents, and annual SAR costs of $44,582±28,972. From 2011 to 2015, the same area saw 54 SAR incidents, 156 victims, 4 fatalities, 35 major incidents, and annual SAR costs of $27,027±19,586. No parameter showed statistical significance. Parkwide SAR incidents decreased from 232 to 198 annual incidents (P=0.013) during the same time period, with parkwide mortality increasing from 8 to 12 deaths annually (P=0.045). CONCLUSIONS: SAR incidents, victims, fatalities, or costs above LYV did not decrease after cable handrail permitting. Parkwide SAR activity decreased during the same intervals. This strongly suggests that overcrowding is not the key factor influencing safety on Half Dome. This discordant trend warrants close observation over 5 to 10 y.

Equestrian-related injuries, predictors of fatalities, and the impact on the public health system in Sweden.

OBJECTIVES: Horse riding is a popular activity but has also been found to lead to many injuries and even fatalities. No reduction in the numbers of those being admitted to hospital for equestrian-related injuries have been seen in Sweden in recent years. The aim of this work was to examine injuries, fatalities, and predictors of fatalities in equestrian-related activities and to investigate the cost of these injuries to the public health system. STUDY DESIGN: The study is a retrospective analysis of hospital data. METHODS: National Swedish hospital and mortality registers were retrospectively examined, inclusive of the years 1997-2014. Logistic regression was used to examine the predictors of fatal injuries, and cost of hospital treatment was considered. RESULTS: Over the study period, there were an observed 29,850 injured cases and 51 fatalities. Women comprized almost 90% of those injured and 70% of fatalities. The average age was 26.8 years (range 0-91, standard deviation [SD] = 16.1) for injured and 43 years (range 7-78 years, SD = 20.5) for fatal cases. Men dominated both injured and fatal samples in the older age ranges (Fatal: >50 years; Injured: >70 years), although overall numbers were small. Injuries to the head contributed more than any other body region for both injured and fatal cases, and fractures were the most frequently seen injury type. A chi-squared analysis confirmed that injury type and injured body region were not independent of age. Logistic regression examining the association between fatality and age, gender, home region, and year of injury, indicating trends over time, found that there was an increase of 5.1% in the odds of fatality for every year increase in age of the patient and men had 2.2 times higher odds to be in the fatal sample than women. The conservative estimated cost of injury was 1800 Euro per injury event, equating to over 3 million Euro per year. CONCLUSION: Equestrian-related injury events present a major public health concern. Observed decreases in fatalities suggest improved health care, yet head injury and fatality rates are still high, indicating a need for further intervention. The type of injury changes with the age group, and a better understanding of injury patterns with age is needed to identify protective measures for the different user groups.

Climbing-Related Injury Among Adults in the United States: 5-Year Analysis of the National Emergency Department Sample.

INTRODUCTION: Rock climbing and mountaineering are popular outdoor recreational activities. More recently, indoor climbing has become popular, which has increased the number of persons at risk for climbing-related injuries. The purpose of this study was to assess the morbidity, mortality, and healthcare cost due to climbing-related injury among persons presenting to US emergency departments (ED). METHODS: We performed a retrospective analysis of the 2010 to 2014 National Emergency Department Sample database, a nationally representative sample of all visits to US EDs. Rock climbing, mountain climbing, and wall climbing injuries were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes (E004.0). Outcomes evaluated included morbidity, mortality, inpatient admission, and costs. Adjusted analyses accounting for survey methodology were performed. RESULTS: A weighted-estimate 15,116 adult ED visits were associated with climbing-related injury. Patient age was 32.8±14.7 (mean±SD) (95% CI: 32.1-33.5) y, and 62% of patients were male. The majority of the injuries occurred in the Western census region (9593; 63%). Less than 1% of all climbing-related visits resulted in death. Only of injury severity score >15 was associated with death (P = 0.005). A total of 1610 (11%) of patients were admitted as inpatients. Accounting for ED and inpatient costs, climbing-related injuries cost the US healthcare system approximately $102 (95% CI: $75-130) million USD for the 5-y period, averaging $20±9.5 million USD per y. CONCLUSIONS: Most persons with climbing-related injuries presenting to EDs do not require inpatient admission. Although death is rare among patients with climbing-related injuries, the costs of injuries in survivors remain high.

Death in Community Australian Football: A Ten Year National Insurance Claims Report.

While deaths are thought to be rare in community Australian sport, there is no systematic reporting so the frequency and leading causes of death is unknown. The aim of this study was to describe the frequency and cause of deaths associated with community-level Australian Football (AF), based on insurance-claims records. Retrospective review of prospectively collected insurance-claims for death in relation to community-level AF activities Australia-wide from 2004 to 2013. Eligible participants were aged 15+ years, involved in an Australian football club as players, coaches, umpires or supporting roles. Details were extracted for: year of death, level of play, age, sex, anatomical location of injury, and a descriptive narrative of the event. Descriptive data are presented for frequency of cases by subgroups. From 26,749 insurance-claims relating to AF, 31 cases were in relation to a death. All fatalities were in males. The initial event occurred during on-field activities of players (football matches or training) in 16 cases. The remainder occurred to people outside of on-field football activity (n = 8), or non-players (n = 7). Road trauma (n = 8) and cardiac conditions (n = 7) were the leading identifiable causes, with unconfirmed and other causes (including collapsed or not yet determined) comprising 16 cases. Although rare, fatalities do occur in community AF to both players and people in supporting roles, averaging 3 per year in this setting alone. A systematic, comprehensive approach to data collection is urgently required to better understand the risk and causes of death in participants of AF and other sports.

State injury prevention policies and variation in death from injury.

OBJECTIVES: Death from injury is frequently preventable, but injury remains a leading cause of death in the USA. While evidence-based strategies exist to prevent many types of injuries, effective policies for implementing these strategies at the population level are needed to reduce injury deaths. We identified promising injury prevention policies and evaluated their association with injury death rate (IDR). METHODS: We identified 11 injury prevention policies and accessed data on 2013 state and county IDRs. States were divided into strong, moderate and weak tertiles based on total number of policies in place. Adjusted regression modelling compared the strength of state prevention policies with IDRs at the state level and then at the county level to account for variability within states. RESULTS: The strength of state prevention policies (tertile) was not significantly associated with IDR in US states. However, counties in strong policy states had a 11.8-point lower IDR compared with those in weak policy states (p=0.001). CONCLUSIONS: States with more injury prevention policies in place have lower rates of death from injury, particularly when evaluated at the county level. Implementing recommended prevention policies holds potential to prevent injury death in the USA.

Dead men walking: search and rescue in US National Parks.

OBJECTIVE: To identify search and rescue (SAR) trends in US National Park Service (NPS) units. METHODS: A retrospective review of the US National Park Service Annual Search and Rescue Reports from 1992 to 2007 and the SAR statistics for all NPS units in 2005. RESULTS: From 1992 to 2007 there were 78,488 individuals involved in 65,439 SAR incidents. These incidents ended with 2659 fatalities, 24,288 ill or injured individuals, and 13,212 saves. On average there were 11.2 SAR incidents each day at an average cost of $895 per operation. Total SAR costs from 1992 to 2007 were $58,572 164. In 2005, 50% of the 2430 SAR operations occurred in just 5 NPS units. Grand Canyon National Park (307) and Gateway National Recreation Area (293) reported the most SAR operations. Yosemite National Park accounted for 25% of the total NPS SAR costs ($1.2 million); Wrangell-St. Elias National Park and Preserve ($29,310) and Denali National Park and Preserve ($18,345) had the highest average SAR costs. Hiking (48%) and boating (21%) were the most common activities requiring SAR assistance. Hiking (22.8%), suicides (12.1%), swimming (10.1%), and boating (10.1%) activities were the most common activities resulting in fatalities. CONCLUSIONS: Without the presence of NPS personnel responding to SAR incidents, 1 in 5 (20%) of those requesting SAR assistance would be a fatality. Future research and the development of any prevention efforts should focus on the 5 NPS units where 50% of all SAR incidents are occurring.

Search and rescue trends and the emergency medical service workload in Utah's National Parks.

OBJECTIVE: To identify the emergency medical service (EMS) workload and trends associated with search and rescue (SAR) operations in Utah's National Park Service (NPS) units. METHODS: Data for this study were collected from the Annual Emergency Medical Services Report and the Annual Search and Rescue Report for National Park Service units in Utah from 2001-2005. RESULTS: There were 4762 EMS incidents reported between 2001 and 2005, including 79 fatalities (50 traumatic; 29 nontraumatic). The most common EMS transportation method was ground (1505) and helicopter (553) transport. The heaviest trauma, medical, and cardiac workload was at Glen Canyon National Recreation Area (GLCA) and the heaviest first aid workload was at Zion National Park (ZION). There were 1190 SAR operations between 2001 and 2005 involving 67 fatalities, 623 ill or injured visitors, 1813 non-ill or non-injured visitors, and 92 saves. GLCA and ZION accounted for 47% and 21% of all SAR operations. The total cost of SAR operations was $1 363 920. SAR operations most commonly occurred on weekends, involved male visitors (59%), visitors aged 20-29 years (23%), and 40-49 years (20%), and visitors participating in day hiking (221), motorized boating (196), and canyoneering (98) activities. Most SAR operations were in lake (226), desert (147), and canyon (140) environments and were resolved within 24 hours. CONCLUSIONS: GLCA and ZION experienced heavy use of EMS resources that should be noted by EMS administrators and planners. GLCA and ZION also reported the most SAR operations. The development of techniques to prevent the need for SAR at GLCA and ZION would likely have the most potential to reduce the financial impact of SAR incidents and morbidity and mortality to visitors.

Career-ending injuries to professional jockeys in British horse racing (1991-2005).

BACKGROUND: It has been previously shown that professional jump and flat racing jockeys suffer a high incidence of injury as a consequence of their profession. This paper specifically examines career-ending injuries to professional jockeys in Great Britain. AIMS: To investigate career-ending injuries in professional jockeys. METHOD: Analysis of prospectively collected injury database on professional jockeys. RESULTS: The majority of injuries in this study occurred to the head, shoulder or torso. Fractures were the most common type of injury that led to a decision to end a career, followed by neurological injury to the head and/or spine. CONCLUSION: Injuries to the head are the most common career-ending injuries, and consideration of injury counter measures could be an important strategy in equestrian sports.

[Risks in mountaineering and trekking]. / Risiken beim Bergwandern und Trekking.

Mass tourism in the mountains is on the increase. The climbers often do not know much about the possible risks which include death, invalidity and sickness. In this article, risks such as AMS (acute mountaine sickness), HACE (high altitude cerebral edema) and HAPE (high altitude pulmonale edema) are shown. These facts should be taken into account for risk assessment in the private insurance industry.

On the epidemiology of sports injuries in Switzerland.

A review of the current literature and of insurance data sources on sports injuries in Switzerland during the latest decade is presented. Epidemiological denominator data to determine the population-at-risk and the exposure time are scarce and it is therefore recommended that both the quantity and the quality of Swiss research in this field will be enhanced. It is also proposed that at least one academic institution in Switzerland would assemble systematically all available data of standard format on sports and recreational injuries to ensure a continuous analysis of these data.
