BACKGROUND
Patient reported outcome measures (PROMs) measure health states in chronic rhinosinusitis (CRS) and have become the dominant metrics of treatment outcomes. Interpersonal traits (IPTs) are patient-specific factors that include personality type, perceived social support, and trust in physicians. The association of IPTs on treatment outcomes among patients with CRS has not been previously described and IPTs may represent important clinical factors influencing treatment outcomes.
METHODS
Adult patients electing medical or surgical treatment for recalcitrant CRS were prospectively enrolled into a multi-institutional, observational outcomes study. Validated measures of IPTs, including: the Big Five Inventory-10 Short Version (BFI-10), Multidimensional Scale of Perceived Social Support (MSPSS) and the Trust in Physician Scale (TPS) were completed and compared to PROMs, including: the 22-item SinoNasal Outcome Test (SNOT-22), the Medical Outcomes Study Short Form-6D (SF-6D), and the Patient Health Questionnaire-2 (PHQ-2).
RESULTS
354 participants were included and followed for an average [±standard deviation] of 16.3 [±4.8] months. Significant within-subject improvement in mean PROM scores was reported (all p<0.001). No association was detected between PROM score improvement and baseline BFI-10 or MSPSS scores (p>0.050). Significant, but weak, absolute correlations were reported between baseline TPS scores and improvement in SNOT-22, SF-6D and PHQ-2 total scores (p<0.050; Rp:≤ 0.138).
CONCLUSIONS
Personality type and perceived social support do not associate with improvement following treatment for CRS. However, increased trust in physicians is weakly associated with greater post-treatment improvement. Further study is needed to examine the relationship between physician trust, patient satisfaction and treatment outcomes among patients with CRS.
