- ItemOpen AccessAssessing inter-rater agreement of environmental audit data in a matched case-control study on bicycling injuries(BMJ Publishing Group, 2013-01-30) Romanow, Nicole T.R.; Couperthwaite, Amy B.; McCormack, Gavin R.; Nettel-Aguirre, Alberto; Rowe, Brian H.; Hagel, Brent E.BACKGROUND: Environmental audit tools must be reliable in order to accurately estimate the association between built environmental characteristics and bicycling injury risk. OBJECTIVE: To examine the inter-rater agreement of a built environment audit tool within a case-control study on the environmental determinants of bicycling injuries. METHODS: Auditor pairs visited locations where bicycling injuries occurred and independently recorded location characteristics using the Systematic Pedestrian and Cyclist Environmental Scan (SPACES). Two case groups were defined: (1) where a bicyclist was struck by a motor-vehicle (MV) and (2) where the bicyclist's injuries required hospitalisation. The two corresponding control groups were (1) where non-MV bicycle-related injuries occurred and (2) where minor bicycle-related injuries occurred. Inter-rater reliability of each item on the tool was assessed using observed agreement and κ with 95% CI. RESULTS: Ninety-seven locations were audited. Inter-observer agreement was generally high (≥95%); most items had a 1-2% difference in responses. Items with ≥5% differences between raters included path condition, slope and obstructions. For land use, path and roadway characteristics, κ ranged from 0.3 for presence of offices and cleanliness to 0.9 for schools and number of lanes; overall, 78% of items had at least substantial agreement (κ≥0.61). For bicyclists struck by a MV the proportion of items with substantial agreement was 60%, compared with 73% for non-MV related injuries. For hospitalisations and minor bicycle-related injuries, 76% of items had substantial agreement. CONCLUSIONS: Agreement was substantial for most, but not all SPACES items. The SPACES provides reliable quantitative descriptions of built environmental characteristics at bicycling injury locations.
- ItemOpen AccessMountain bike terrain park-related injuries: an emerging cause of morbidity(Taylor & Francis Online, 2012-12-18) Romanow, Nicole T.R.; Hagel, Brent E.; Nguyen, Michelle; Embree, Tania; Rowe, Brian H.This case–control study describes the profile of bicyclists injured in mountain bike terrain parks (MBTPs) and examines risk factors for severe injury among MBTP riders. Cases were hospitalised bicyclists injured in MBTPs. Controls were bicyclists injured in MBTPs who were discharged from the emergency department. No significant differences were observed in the distribution of age and sex between cases and controls. A higher proportion of cases compared with controls suffered a head injury (22%), fracture (41%) or internal organ injury (32%). Controls suffered a higher proportion of superficial injuries (26%), sprains (10%) or wounds (16%). Upper extremity protective equipment (e.g. elbow or shoulder pads) was used more by cases than controls (23% vs. 11%, p = 0.03). Riders who self-reported cycling faster than usual had significantly higher risk of severe injury compared with others. The risk of severe injury may be reduced by encouraging bicyclists to control their speed or by modifying MBTP design to limit the opportunity to gain speed.
