title: Role of maxillofacial trauma scoring systems in determining the economic burden to maxillofacial trauma patients in India.
abstract: BACKGROUND
  The objective of this study was to evaluate the association between severity of maxillofacial injuries determined by trauma scoring systems and its economic burden to patients in terms of cost and duration of hospitalization.
  
  
  METHODS
  Following ethical approval a retrospective chart review was undertaken at Meenakshi Ammal Dental College and Hospital to identify patients admitted with maxillofacial injuries between January 2006 and December 2008. Patients with incomplete records, associated injuries, debilitating systemic diseases and patients treated under local anesthesia were excluded. Details regarding the nature and severity of injury and treatment were recorded in addition to the total treatment cost and duration of hospitalization. Maxillofacial injury severity was scored using maxillofacial injury severity score (MFISS) and facial injury severity scale (FISS). The MFISS and FISS scores were correlated with two surrogate markers of the economic burden namely cost and duration of hospitalization.
  
  
  RESULTS
  A total of 162 patients with maxillofacial injuries were identified (108 males, 54 females; mean age = 32.4 years). Road traffic accidents were the cause of injury in 114 patients (70.4%) and only 29 patients (17.9%) had medical insurance coverage. The mean MFISS and FISS scores were 14.04 (standard deviation [SD] = 9.19; range = 3-42) and 4.40 (SD = 3.17; range = 1-14), respectively. The mean cost and duration of hospitalization of the patients were Indian rupees (INR) 13877.28 (SD = 8252.59; range = INR 5250-42960) and 4.12 days (SD = 1.5; range = 2-8 days) respectively. Pearson's correlation between the MFISS and FISS scores and the cost and duration of hospitalization, revealed statistically significant correlations (MFISS vs. cost - R = 0.862, P < 0.001; MFISS vs. duration - R = 0.828, P < 0.01; FISS vs. cost - R = 0.845, P < 0.01; FISS vs. duration - R = 0.819, P < 0.01).
  
  
  CONCLUSIONS
  Based on the results of this study, maxillofacial injury severity measured by MFISS and FISS scores are predictable indicators of the economic burden to the patients.
