Summary results
Survey data analysis is one of the three main sources of information on occurrence of injuries in particular non-fatal ones. In many occasions, surveys are the only source of information of this type. In developing countries where there exists a huge epidemiologic information gap survey data make us able to estimate the incidence of the injury events. Here, we present a summary of results of different survey data sources we have accessed. They come into two spreadsheets. First one are results of our analysis on the World Health Survey. The second spreadsheet is supposed to present a summary of the published peer-reviewed papers or scientific reports on injury epidemiology. The latter work has yet to be completed.
World Health Organization (WHO) launched the World Health Survey(WHS) between 2002-2003 in 55 developing countries. WHS is a national interview based survey which aims to put together through baseline information on the health of population on people aged 18 years and above. This survey has two alike series of injury related questions. The first set is about total non-fatal injuries except road traffic injuries (RTI) and the second set is exclusively about non-fatal RTIs. Unfortunately the non-RTI questions do not specify the type of the injury sustained. Thus, we only analyzed the RTI related questions. Spreadsheet Number 2 conveys incidence rate (per 1000 population) of total RTI and RTI by three age groups, gender, and place of residence (urban-rural) at country level. We also provide information on the fraction of injured people utilized different types of healthcare. Sample weights were used for the analyses. We are aware of the potential effect of recall bias on the estimates. However, we preferred not to display the estimates before correction for recall bias. The adjustment can be done through multiplying the rates by 1.82. If you have any questions about the methods we used please contact us (contact information can be found below).
Published peer-reviewed papers and scientific reports on injuries are very scattered. We recently set out an extensive structured search through PubMed and other similar databases to collect and summarize the relevant injury surveys from around the world. The results of this ongoing effort are put in the spreadsheet Number 1 below. Until present we have found 20 relevant publications. The work of summarizing these publications are continuing and we keep updating this sheet. So, if you are a user of the information please check this link periodically to get the latest revision. Also, we are eagerly looking to add more survey data sources to this collection. Should you know of a similar study that has not been included in the list we would like to hear from you (please see the survey data request section below).
Survey data request
The Global Burden of Disease project will generate estimates of the burden of injuries broken down by external cause, age and sex. We have provided an Excel file that contains information on how you can share your survey data with us. We know that you might not be able to generate detailed information at the level we request. Thus, we are asking that you provide us with the maximum level of detail possible. Should we publish any piece of information from your data we will refer that piece of information to you. You can get the Excel file from the bottom of this page. It is called "Survey data request". Please, reproduce the tab (worksheet) "Sample-RTI" for as many of the external causes listed in the README tab of the Excel file. If you have any questions on how to fill the spreadsheets out please do not hesitate to contact us.
