Application of loglinear modelling to inpatient data for temporomandibular joint disorder claimants
The primary purpose of this paper was to demonstrate the application of loglinear modelling to the analysis of inpatient hospital claims data for TMD claimants. The database of a major medical insurer was used to study 1,819 patients who were diagnosed and treated for TMD along with their Non-TMD matches. Using loglinear modelling, it was found that Major Diagnostic Categories and TMD were not independent variables. Further, three categories were significantly related to patients with TMD Neoplasmand Pregnancy showed a significant inverse relationship while Digestive System showed a significant direct relationship. These findings provide healthcare providers with a better understanding of TMD and its relationship to disorders that lead to patient hospitalisation.
