Background: A data acquisition from the medical sector may give one important view of the burden on the society caused by vehicle related injuries. The official police-reported statistics may only reflect a part of all vehicle-related injured seeking medical attention. The aim is to provide a comprehensive picture of the burden of vehicle related injuries on the medical sector (2013), and to compare with official police-reported statistics and the development year 2000-2013.

The aim of this paper is to analyse and compare injuries and injury sources in pedestrian and bicyclist non-fatal real-life frontal passengercar crashes, considering in what way pedestrian injury mitigation systems also might be adequate for bicyclists. Data from 203 non-fatal vehicle-to-pedestrian and vehicle-to-bicyclist crashes from 1997 through 2006 in a city in northern Sweden were analysed by use of the hospitals injury data base in addition to interviews with the injured. In vehicle-to-pedestrian crashes (n = 103) head and neck injuries were in general due to hitting the windscreen frame, while in vehicle-to-bicycle crashes (n = 100) head and neck injuries were typically sustained by ground impact.

Clearing snow from roofs causes serious injuries annually. The aim of this study was to describe injury mechanisms, injury panorama, and injury incidence in connection to this activity. A specific aim was to study the association between snow depth and injury incidence.

Background: Abdominal injuries occur relatively infrequently during trauma, and they rarely require surgical intervention. In this era of non-operative management of abdominal injuries, surgeons are seldom exposed to these patients. Consequently, surgeons may misinterpret the mechanism of injury, underestimate symptoms and radiologic findings, and delay definite treatment.

Designing effective vehicle-based countermeasures for vulnerable road users demands an understanding of the relationship between injury and injury source. The aim of this study was to explore this association for bicyclists in fatal real-life-crashes. All fatal crashes in Sweden where a bicyclist was killed when hit by the front of a passenger car between 2002 and 2008 were studied in detail using on-scene data.

Objective: To examine the annual incidence of acute whiplash injuries after road traffic crashes in a geographic catchment area in Northern Sweden during the period 2000-2009.

Design: Descriptive epidemiology determined by prospectively collected data from a defined population.

Setting: The study was conducted at a public hospital in Sweden.

Background: The purpose of this study was to investigate if teenagers visiting an emergency room because of injury have an increased risk of premature death ahead and, if so, identify possible risk factors and suggest preventive measures.

Methods: In January 2010, the personal identity numbers of 12,812 teenagers who had visited the emergency room at the University Hospital in Umeå, Sweden, during 1993 through 2006 because of injury were checked against the National Cause of Death Register in Sweden. Standardised mortality ratio and confidence intervals were calculated.

Bicycles are a common mode of transportation and injured bicyclists cause a substantial burden on the medical sector. In Sweden, about half of fatally injured bicyclists are 65 years or older. This study analyzes the injury mechanisms, injuries, and consequences among bicyclists 65 years or older and compare with younger bicyclists (< or =64) and older adults as passenger car drivers, to give a basis for an injury preventive discussion for this age group.

Previous research has pointed out that non-collision injuries occur among wheelchair users in Special Transportation Services (STS - a demand-responsive transport mode). The organization of such modes is also quite complex, involving both stakeholders and key personnel at different levels. Our objective was therefore to qualitatively explore the state of safety, as perceived and discussed within a workplace context.

Previous research has shown that wheelchair-seated passengers using special transportation services (STS) have been injured without being involved in a vehicle crash. In order to estimate incident rate and societal costs for these vehicle-related injuries, the focus needs to be adjusted towards a traveler/incident-oriented perspective. The aim of the project was to utilize such a perspective, related to travelers using STS in Sweden.

This study analyzes accidental fatalities caused by electricity--at work and during leisure time--to evaluate risk factors, the role of alcohol, and to identify possible preventive strategies. In Sweden, data on fatalities by electrocution from 1975 through 2000 were collected from the National Cause-of-Death Register. Additional cases were found in the archives of The Swedish National Electrical Safety Board.

Using insurance data, medically impairing injuries sustained by 111 firefighters were analyzed. The injury incidence per year among full-time working firefighters was 39 per 10 000, and among part-time working firefighters 6 per 10 000. More than half (51%) were injured during fitness training, 14% during job training, and 13% during emergency response, while 4% were injured in traffic crashes and 18% in other injury events.

Medically impairing injuries among medical personnel (n = 209) were analyzed based on data obtained from the Work-Related No-Fault Liability Insurance's (TFA) injury registration system. Almost half (98; 47%) were injured during patient care, of which 29 were injured as a result of physical trauma inflicted by the patient. When moving themselves between the homes of the patients and between different wards, 94 (45%) were injured (18 in vehicle crashes).

Injuries due to interaction with dogs and cats are not uncommon, and constituted 1.4% of all injuries in an unselected policlinical and inpatient material. This material was collected from a population of 135,000 people in Northern Sweden, and during 2 years 280 patients with injuries related to these domestic animals were found (Ndogs = 212, Ncats = 68).
