I. Dalkie’s model for investigation road-safety issues overview
a. Facilitation between groups to recommend better injury-prevention strategies
i. Police
ii. Hospitals
iii. Injury-Control Center
iv. EMS/Fire Department
v. Injury-Analysis Team (works with all other groups simultaneously)
b. At first I was confused with the model, however when it is laid out in front of me I can understand why these groups all need to work together to better injury prevention.
c. Example: Student Services Building
i. Connects areas of the school with each other
ii. Works as messenger from on department to the next
II. Sensitivity and Specificity of the Model
a. Definitions
i. Sensitivity – the availability to include all cases of a particular motor-vehicle collision injury
ii. Specificity – the ability to exclude other phenomena that may be mistake for the one being studied
b. I think it is very important to look at the sensitivity and specificity of the model because it helps to reduce error. After taking a research methods class, I realized how important it is to make sure that one looks at the study from many different angles because it is easy to make mistakes that can skew your results dramatically.
c. Example: The Model only wanted to look at serious accidents that required EMS care and transportation to a trauma center, however they many of the accidents that they originally thought of as being “low-severity” crashes, were re-categorized as “serious” after the victim was in the hospital. Therefore the researchers missed out on the on-site investigations of these cases.
III. Applying the Model
a. The analysis begins at the site of the accident where the injury analysis team works with the police to create a collision summary without interfering with the police investigation. They would then look send the collision summary to the hospital to help the medical staff better understand the accident and therefore better help the victim. The emergency physicians would then provide the injury analysis team with the records about the patient’s injuries. The team would then analyze all the collected data and work to improve injury-prevention measures.
b. I think it is important to understand how people working together can benefit from each other, rather than believe that they are just getting in each other’s way. I believe that it is important to have a team of people looking at every aspect of the accident to try to come up with ways to prevent the accident from happening in the future.
c. Example: 17-year old female driver hitting lamp post
