Baseline clinical characteristics predict follow-up clinic attendance in patients undergoing endoscopic sinus surgery for chronic rhinosinusitis

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.
