ABSTRACT
Objective
To summarize the literature that has examined the association between a motor vehicle collision (MVC) related neck injury and future neck pain (NP) in comparison with the population that has not been exposed to neck injury from an MVC.
Literature Survey
Neck injury resulting from a MVC is associated with a high rate of chronicity. Prognosis studies indicate 50% of injured continue to experience NP a year after the collision. This is difficult to interpret due to the high prevalence of NP in the general population.
Methodology
We performed a systematic review of the literature using five electronic databases, searching for risk studies on exposure to a MVC and future NP published from 1998 to 2018. The outcome of interest was future NP. Eligible risk studies were critically appraised using the modified Quality in Prognosis Studies (QUIPS) instrument. The results were summarized using best‐evidence synthesis principles, a random effects meta‐analysis, meta‐regression and testing for publication bias was performed with the pooled data.
Synthesis
Eight articles were identified of which seven were of lower risk of bias. Six studies reported a positive association between a neck injury in an MVC and future NP compared to those without a neck injury in a MVC. Pooled analysis of the six studies indicated an unadjusted relative risk of future NP in the MVC exposed population with neck injury of 2.3 (95% CI [1.8, 3.1]), which equates to a 57% attributable risk under the exposed. In two studies where exposed subjects were either not injured or injury status was unknown, there was no increased risk of future NP.
Conclusions
There was a consistent positive association among studies that have examined the association between MVC‐related neck injury and future NP. These findings are of potential interest to clinicians, insurers, patients, governmental agencies, and the courts.
