Purpose
This study attempts to provide insight on how the treatment preference for a mandible fracture and treatment received and its consequences, are related to the patient’s risk tolerance, as measured by the Standard Gamble(SG).
Patients and Methods
Data from a prospective cohort study of 203 subjects receiving treatment at the former King/Drew Medical Center (KDMC) in Los Angeles for either a mandible fracture(n=98) or third-molar removal (n=105) are examined. Subjects were interviewed at four time points; upon admission to the medical center, and at three monthly follow-up visits. Risk tolerance for hypothetical treatment scenarios is measured using the SG, a health-value utility measure assessing the tradeoff between good outcomes and serious complications associated with treatment. Separate regression analyses with subsets of predictors (sociodemographic, psychosocial health, and clinical characteristics) were conducted and then synthesized using the significant predictors in separate analyses.
Results
For fracture subjects, there is a noticeable rise in the SG reports from admission to the one-month follow-up. Their greater risk tolerance was associated with being older, receiving surgery, having a lower PTSD score, and having a swollen jaw or face. For third-molar subjects, SG does not change substantively over the course of the study. Predictors of greater risk tolerance for third molar subjects include the jaw or face being swollen and having to use less pain medication.
Conclusions
Findings from this study demonstrate a preference for less invasive treatment, with the majority of both groups preferring wiring and support the theory that treatment choices differ between subjects with different health states. Factors associated with risk tolerance include the patient’s age, treatment received, psychosocial health state, experience with prior treatment, and value for oral health quality of life.
