RESUMEN
BACKGROUND: The objective of this work was to describe the association between baseline clinical characteristics and attendance at follow-up visits after endoscopic sinus surgery (ESS). METHODS: A retrospective review of chronic rhinosinusitis (CRS) patients electing ESS at a tertiary-care center (2011-2013) was conducted. Baseline characteristics were studied for association with clinic attendance at 3, 6, 12, and 24 months post-ESS. RESULTS: We identified 268 patients. Significant decline occurred in the number of patients following up after ESS (3 months: 246 patients [92%]; 6 months: 145 [54%]; 12 months: 94 [35%]; and 24 months: 90 [34%]). Older patients were more likely to follow up at 3 months (mean age 55.7 vs 48.4 years, p = 0.04) and 6 months (57.5 vs 52.3 years; p = 0.01) post-ESS. Those with higher preoperative sinus computed tomography (CT) (Lund-Mackay) scores were more likely to follow at 6 months (11.8 vs 10.3, p = 0.01), 12 months (12.6 vs 10.3, p < 0.001), and 24 months (12.2 vs 10.5, p = 0.01). At 12 months having asthma (p = 0.03), previous ESS (p = 0.04), nasal polyps (p < 0.0001), allergic fungal sinusitis (AFS) (p = 0.002), and granulomatosis with polyangiitis (GPA) (p = 0.01) were associated with clinic attendance. At 24 months asthma status (p = 0.003), previous ESS (p = 0.002), AFS (p = 0.04), GPA (p = 0.001), and aspirin-exacerbated respiratory disease (AERD) (p = 0.006) were associated with higher attendance. Geographical proximity did not impact attendance. CONCLUSION: The sharpest decline in patient follow-up occurred between 3-6 months after ESS. Higher preoperative sinus CT scores, previous ESS, presence of asthma, and diagnosis of recalcitrant CRS subtype (nasal polyps, AERD, AFS, GPA) were factors associated with increased long-term attendance.
