Background & Aims

Pain after trauma has been solicitude since time immemorial. Maxillofacial trauma(MFT) includes bony facial injuries causing surmountable pain due to its physiological role. Open reduction Internal Fixation and closed reduction are standard treatment protocols. 1-3
Pain quantification in MFT patients as MCID and its role in patients satisfaction will help surgeons to provide patient-centric care. Minimal Clinical Important Difference MCID is meaningful change (improvement or deterioration) of any clinically relevant parameter, in patient’s perspective4. MCID has been established for dyspnoea, pain, and function in orthopedic and pulmonary patients 5, 6 MFT patients form a different sect of population, and their MCID has never been determined. Further pain may predict patients’ satisfaction, this was done by Patient’s Acceptable Symptomatic State (PASS)6. Our study aimed to determine MCID of pain, assessed PASS and evaluated pain as a predictor of patient’s satisfaction in MFT.

Methods

A single-center prospective study was designed and included 120 MFT patients and was rendered standard of care as per AO principles. A detailed structured proforma containing, socio-demographics, type and etiology of fractures, rendered treatment, and relevant clinical and radiographic parameters were assessed. Preoperative (T1) and 4 weeks postoperative (T2) pain scores as VAS-NRS were recorded. All the patients were evaluated by a 4-item question assessing the pain improvement after treatment on a Likert scale at T2, which served as an anchor instrument to determine MCID. Further, a 4-item patient satisfaction Tubach’s anchor instrument was used to assess patient satisfaction at T2. MCID of pain was calculated using Change difference and ROC curve method of anchor-based approach. PASS score was calculated as 75th percentile of VAS NRS pain score who were satisfied with treatment. Further pain was assessed as a predictor of satisfaction using logistic regression analysis.

Results

Study participants mean age was 31.7 ± 11.9 years. The study participants comprised 90 males (94.73%) and 5 females (5.27%) and were managed with closed reduction (9.17%) or ORIF (90.83%). The mean VAS NRS was 8.21± 1.23 T1 which improved to 1.53 ± 0.94 at T2. The MCID of pain on VAS-NRS was 2.4 by the change difference method and 2.5 by the ROC curve method (Sensitivity of 91.7% and specificity of 61.1%). The estimated PASS was 2 on VAS-NRS. The patient satisfaction with treatment was rated as “Good” by 30% (36/120) subjects and “Excellent” by 70% (84/120) subjects. A logistic regression model with patient-reported satisfaction as the outcome revealed pain (p < 0.01) as a significant predictor of patient satisfaction.

Conclusions

With this study we have established MCID of pain by two methods and values have come close enough. Further pain in MFT patients came out to be a significant predictor for patient satisfaction. There is an increasing need to use Patient-related outcome measures(PROs) like MCID, PASS and patient satisfaction predictors as true measures of treatment success in addition to objective clinical and radiographic criteria evaluated by surgeons.
