10 The number of patients with a vertebral fracture is expected to increase because of the increasing life expectancy, the increasing numbers of older fallers, and the increasing numbers of osteoporotic individuals in the population.11, 12?and?13 However, there are few data on time trends of healthcare demand due to clinical vertebral fractures. The aim of this [http://www.selleckchem.com/products/Erlotinib-Hydrochloride.html Erlotinib] study was to analyse time-trends in clinical vertebral fractures by analyzing trends in emergency department (ED) visits and hospitalization rates after ED visit. Data on ED visit due to a vertebral fracture in the Dutch population aged 65 years and over was extracted from the Dutch Injury Surveillance System (LIS). The LIS database is a continuous monitoring system in which injury diagnoses and injury mechanisms are registered by using the International Classification of Diseases of the World Health Organization (ICD 10th revision).14 LIS is based on 13 geographically distributed EDs in the Netherlands, resulting in a representative 12% sample of injury-related ED visits. Numbers were extrapolated to national estimates. An extrapolation factor was calculated by the Consumer and Safety Institute (Amsterdam, the Netherlands) based on the adherent population of the participating hospitals and Dutch population numbers in each year of the study. The database makes it possible to measure and describe healthcare use during a specific period. [http://en.wikipedia.org/wiki/MCF2L MCF2L] The full-model description has been published by the Consumer [http://www.selleckchem.com/products/AP24534.html Ponatinib supplier] and Safety Institute, Amsterdam and has been used previously.15, 16?and?17 The model was applied to all persons aged 65 years and older who attended an ED between 1986 and 2008. A vertebral fracture was defined using the ICD 10th revision.14 Vertebral fractures were selected based upon the registered primary diagnosis in the LIS. In case of multiple injuries, the primary injury in LIS was determined by application of an algorithm giving priority to spinal cord injury, skull and brain injury, and lower extremity injury above injuries in other body parts, and to fractures above other types of injury to determine the most serious injury. Numbers of ED visits due to vertebral fractures were specified for age and gender. Furthermore, discharge was registered as treated-and-released or treated-and-admitted to calculate the admission rate. Age-specific rates were calculated in 5-year age groups. The overall age-adjusted incidence rate for the population aged 65 years and older was calculated by using ��Direct Standardization�� to correct for changes in demographics. Incidence rates were expressed per 100,000 person years. A linear regression analysis was used to analyse the age-adjusted incidence rate of vertebral fracture related ED visits over time. The statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS) software (version 16.1.1). A p-value?
