Chronic rhinosinusitis disease burden is associated with asthma-related emergency department usage.

PURPOSE: Chronic rhinosinusitis (CRS) disease burden is associated with pulmonary status in asthmatic CRS patients. Asthma-related emergency department (ED) usage is a predictor of asthma-related mortality. We sought to determine whether measures of CRS disease burden are associated with asthma-related ED usage. METHODS: We prospectively recruited 263 asthmatic CRS patients for this cross-sectional study. CRS burden was measured using the 22-item Sinonasal Outcome Test (SNOT-22), and patient-reported CRS-related antibiotic usage and CRS-related oral corticosteroids usage over the preceding year. Asthma-related ED visits over the prior year were also assessed. RESULTS: Of all participants, 18.6% had at least 1 asthma-related ED visit (mean 0.3 ED visits for the whole cohort). Asthma-related ED usage was associated with SNOT-22 score [adjusted rate ratio (RR) = 1.02, 95% CI 1.01-1.03, p = 0.040] and CRS-related oral corticosteroids usage in the past year (RR = 1.52, 95% CI 1.26-1.83, p < 0.001). From the SNOT-22 score, asthma-related ED usage was only associated with the nasal subdomain score (RR = 1.08, 95% CI 1.03-1.13, p = 0.001). These measures of CRS disease burden could be used with good sensitivity and specificity to detect patients with asthma-related ED usage in the past year, the majority of whom were undertreated for their asthma. CONCLUSIONS: Measures of CRS disease burden are associated with and can be used to detect, patients having asthma-related ED usage. These results further solidify the connection between CRS and asthma disease courses, and also present an opportunity to use CRS disease burden as a tool for identifying-and implementing greater treatment of-patients at highest risk for asthma-related mortality.

Longitudinal improvement in nasal obstruction symptoms of chronic rhinosinusitis directly associates with improvement in mood.

PURPOSE: The effects of nasal obstruction in patients with chronic rhinosinusitis (CRS) are associated with depressed mood. We sought to validate this finding by determining whether improvement in nasal obstruction would translate to improvement in depressed mood. METHODS: This was a prospective observational study of 150 patients undergoing medical management for CRS. Data were collected at two timepoints: enrollment and a subsequent follow-up visit 3-12 months later. Impact of nasal obstruction was measured using the Nasal Obstruction Symptom Evaluation (NOSE) instrument and depressed mood was measured using the 2-item Patient Health Questionnaire (PHQ-2). Sinonasal symptoms associated with CRS were also measured using the 22-item Sinonasal Outcome Test (SNOT-22). Clinical and demographic characteristics were collected. The relationship between changes in PHQ-2 and NOSE scores was determined with correlation and linear regression. RESULTS: Change in PHQ-2 score was significantly correlated with change in NOSE score (ρ = 0.30, p < 0.001). After controlling for covariates, change in PHQ-2 score was associated with change in NOSE score (adjusted linear regression coefficient [ß] = 0.014, 95% CI 0.006-0.022, p = 0.001). We confirmed these relationships, finding that change in PHQ-2 was associated (adjusted ß = 0.037, 95% CI 0.013-0.061, p = 0.003) with change in the nasal subdomain score of the SNOT-22. Improvement in NOSE score by greater than 22 points was predictive of improvement in PHQ-2 score with sensitivity 54.5% and 83.8% specificity (p < 0.001). CONCLUSION: These results provide evidence that improvements in nasal manifestations/symptoms of CRS translate to significant improvements in mood.

Changes in chronic rhinosinusitis symptoms differentially associate with improvement in general health-related quality of life.

BACKGROUND: Previous work has shown that the symptoms of chronic rhinosinusitis (CRS) differentially associate with decreased general health-related quality of life (QOL). OBJECTIVE: We sought to determine whether longitudinal changes in different types of CRS symptomatology lead to correspondingly different magnitude changes in general health-related QOL. METHODS: Prospective observational study of 145 patients undergoing medical management for CRS. Chronic rhinosinusitis symptom severity was measured using the 22-item Sinonasal Outcome Test (SNOT-22) and associated nasal, sleep, ear/facial discomfort, and emotional subdomains of the SNOT-22. General health-related QOL was measured using the 5-dimensional EuroQoL questionnaire's visual analog scale (EQ-5D VAS). These data were collected at 2 time points: at enrollment and at a subsequent follow-up visit within the next 2 to 6 months. Associations were sought between the changes in SNOT-22 and EQ-5D VAS. RESULTS: The change in SNOT-22 was associated with change in EQ-5D VAS (adjusted linear regression coefficient [ß] = -0.37, 95%CI: -0.51 to -0.24, P < .001). The change in EQ-5D VAS was only associated with changes in the sleep (adjusted ß = -0.42, 95% confidence interval [95%CI]: -0.81 to -0.04, P = .034) and ear/facial discomfort (adjusted ß = -1.00, 95%CI: -1.89 to -0.10, P = .031) subdomains but not nasal (adjusted ß = -0.12, 95%CI: -0.52 to 0.28, P = .564) or emotional (adjusted ß = -0.17, 95%CI: -1.83 to 1.49, P = .840) subdomains. CONCLUSION: Changes in the severity of sleep and ear/facial discomfort symptoms associate most greatly with the change in general health-related QOL that CRS patients experience during routine medical management. Reduction of these extranasal symptoms of CRS may therefore lead to the greatest improvement in general health-related QOL.

Impact of odontogenic chronic rhinosinusitis on general health-related quality of life.

Chronic rhinosinusitis (CRS) may arise due to odontogenic etiologies. However, it is unknown whether odontogenic CRS has a differential impact on patients' quality of life (QOL) compared to standard, inflammatory (but non-odontogenic) CRS. The objective of this study was to determine whether there is a difference in the impact of sinonasal symptomatology on general health-related QOL in odontogenic CRS compared to non-odontogenic CRS. This was a retrospective review of 21 odontogenic CRS patients who visited our tertiary care center. The severity of sinonasal symptomatology and CRS-specific QOL detriment was measured using the 22-item Sinonasal Outcomes Test (SNOT-22) and general health-related QOL was measured using the health utility index from the 5-item EuroQol survey (EQ-5D HUV). Compared to non-odontogenic CRS, odontogenic CRS was not associated with a difference in SNOT-22 score [linear regression coefficient (ß) = - 1.57, 95% CI - 12.47 to 9.32, p = 0.777] but was significantly associated with decreased EQ-5D HUV (ß = - 0.10, 95% CI - 0.17 to - 0.03, p = 0.008). We also found that the magnitude of association (ß) between SNOT-22 and EQ5D-HUV was greater for odontogenic CRS patients compared to non-odontogenic CRS patients (p = 0.045). Our findings suggest sinonasal symptoms may have a greater impact on general QOL in odontogenic CRS compared to non-odontogenic CRS. The reason for this remains unknown, but deserves further study.

Minimal clinically important difference for the 22-item Sinonasal Outcome Test in medically managed patients with chronic rhinosinusitis.

OBJECTIVE: To determine the minimal clinically important difference (MCID) of the 22-item Sinonasal Outcome Test (SNOT-22) in individuals undergoing medical management for their chronic rhinosinusitis (CRS). DESIGN: Prospective observational study. SETTING: Academic, tertiary care centre. PARTICIPANTS: A total of 247 adults undergoing medical management for CRS. MAIN OUTCOME MEASURE: At enrolment, participants completed a SNOT-22. At a subsequent follow-up visit, 2-12 months after enrolment, participants also completed a SNOT-22. At follow-up, participants also rated the change in their sinus symptoms and general health as "Much worse," "A little worse," "About the same," "A little better" or "Much better" compared with enrolment; these two questions were used as sinus symptom and general health anchor questions, respectively. The SNOT-22 MCID was calculated using distribution-based, anchor-based and receiver operating characteristic (ROC) curve-based methods. RESULTS: Using the distribution-based method, the SNOT-22 MCID was 11.6. Using the sinus symptom anchor question, the SNOT-22 MCID was 10.5; applying the ROC method to the sinus symptom anchor yielded an MCID of 12.5. In comparison, using the general health anchor question, the SNOT-22 MCID was 8.3; applying the ROC method to the sinus symptom anchor yielded an MCID of 17.5. In all cases, the calculated MCID had a sensitivity of approximately 50-60% and specificity of approximately 80-90%. CONCLUSIONS: Based on our results, we propose a SNOT-22 MCID of 12 in medically managed patients with CRS. The MCID, while specific, was not sensitive for identifying patients with CRS experiencing a noticeable improvement in sinus symptoms or general health.

Depression symptoms and lost productivity in chronic rhinosinusitis.

BACKGROUND: Chronic rhinosinusitis (CRS) is associated with significant losses of patient productivity that cost billions of dollars every year. The causative factors for decreases in productivity in patients with CRS have yet to be determined. OBJECTIVE: To determine which patterns of CRS symptoms drive lost productivity. METHODS: Prospective, cross-sectional cohort study of 107 patients with CRS. Sinonasal symptom severity was measured using the 22-item Sinonasal Outcomes Test, from which sleep, nasal, otologic or facial pain, and emotional function subdomain scores were calculated using principal component analysis. Depression risk was assessed with the 2-item Patient Health Questionnaire (PHQ-2), whereas nasal obstruction was assessed with the Nasal Obstruction Symptom Evaluation (NOSE) instrument. Lost productivity was assessed by asking participants how many days of work and/or school they missed in the last 3 months because of CRS. Associations were sought between lost productivity and CRS symptoms. RESULTS: A total of 107 patients were recruited. Patients missed a mean (SD) of 3.1 (12.9) days of work or school because of CRS. Lost productivity was most strongly associated with the emotional function subdomain (ß = 7.48; 95% confidence interval [CI], 5.71-9.25; P < .001). Reinforcing this finding, lost productivity was associated with PHQ-2 score (ß = 4.72; 95% CI, 2.62-6.83; P < .001). Lost productivity was less strongly associated with the nasal symptom subdomain score (ß = 2.65; 95% CI, 0.77-4.52; P = .007), and there was no association between lost productivity and NOSE score (ß = 0.01; 95% CI, -0.12 to 0.13; P = .91). CONCLUSION: Symptoms associated with depression are most strongly associated with missed days of work or school because of CRS. Further treatment focusing on depression-associated symptoms in patients with CRS may reduce losses in productivity.

Association of severity of chronic rhinosinusitis with degree of comorbid asthma control.

BACKGROUND: Comorbid chronic rhinosinusitis (CRS) is associated with worse asthma control. However, no study has investigated whether CRS severity affects the degree of asthma control. OBJECTIVE: To determine the effect size of an association between CRS severity and asthma control. METHODS: A pilot study with a prospective cross-sectional design. Adult patients with CRS and asthma were recruited. CRS severity was measured using the 22-item Sinonasal Outcomes Test (SNOT-22), and asthma control was measured using the Asthma Control Test (ACT). Poor asthma control was defined as an ACT score of 19 or less. In addition to age and sex, we also assessed the participants' history of smoking, aeroallergen hypersensitivity, the presence of polyps, and current use of a corticosteroid-containing asthma inhaler. The association between SNOT-22 and ACT was assessed using univariate and multivariable linear regression. RESULTS: A total of 40 patients were recruited. The mean (SD) SNOT-22 score was 43.6 (23.6), and the mean (SD) ACT score was 20.6 (4.8). We found that the SNOT-22 score was associated with the ACT score (adjusted ß = -0.07; 95% confidence interval [CI], -0.13 to -0.02; P = .02) and with having poor asthma control (adjusted odds ratio, 1.06; 95% CI, 1.01-1.11; P = .02). A SNOT-22 cutoff score of 45 or higher had the greatest association with uncontrolled asthma (adjusted odds ratio, 14.96; 95% CI, 1.93-115.89; P = .01). CONCLUSION: CRS severity is negatively associated with asthma control in patients with asthma and CRS. On the basis of this pilot study, further study is warranted to elucidate the effect of CRS severity on asthma control and to determine whether reduction in CRS severity translates to improvement in asthma control.

Intranasal corticosteroids and saline: Usage and adherence in chronic rhinosinusitis patients.

OBJECTIVE: Intranasal saline irrigations and intranasal corticosteroids are supported by level-1 evidence for medical management of chronic rhinosinusitis (CRS). We sought to study adherence with these medications. METHODS: Prospective study of 174 patients with CRS. Patients reported their usage of intranasal saline irrigation and intranasal corticosteroid over the preceding 3 months, at presentation, and a subsequent follow-up visit 3 to 12 months later. Adherence was defined as reported medication usage for ≥6 days per week. RESULTS: At the time of presentation, 44.3% of patients were using an intranasal corticosteroid spray or irrigation ≥6 days/week, whereas only 24.1% were using saline irrigation ≥6 days per week. At follow-up, 60.3% of patients were using either an intranasal corticosteroid spray or irrigation ≥6 days per week, whereas 35.6% were using saline irrigation ≥6 days per week. Adherence with intranasal corticosteroids was associated with comorbid asthma (adjusted odds ratio [OR] = 2.68, 95% confidence interval [CI]: 1.10-6.50, P = 0.029), allergy (OR = 2.22, 95% CI: 1.05-4.71, P = 0.037), and change in 22-item Sinonasal Outcome Test score (OR = 0.98, 95% CI: 0.96-0.99, P = 0.027). Use of intranasal corticosteroid sprays versus irrigations (OR = 2.56, 95% CI: 0.84-7.83, P = 0.099) was suggestive of association with improved adherence. Adherence with intranasal saline irrigation was associated with age (OR = 1.02, 95% CI: 1.01-1.05, P = 0.034). CONCLUSION: Usage and adherence with intranasal steroids and saline may be low in CRS patients even with management in a tertiary level, subspecialty rhinology clinic. Adherence with medications represents a major opportunity for improving patient care and outcomes, specifically by targeting patients with lower disease burden and improving convenience of medications.

Appropriate medical management of chronic rhinosinusitis reduces use of antibiotics and oral corticosteroids.

OBJECTIVES/HYPOTHESIS: Antibiotics and oral corticosteroids are used in the treatment of acute exacerbations of chronic rhinosinusitis (AECRS) and reflect poor disease control. We sought to characterize utilization of these systemic medications after appropriate medical management of chronic rhinosinusitis (CRS). STUDY DESIGN: Prospective observational study. METHODS: One hundred fifty patients undergoing medical management for CRS were studied. Data were collected at enrollment and follow-up 3 to 12 months later. All patients were asked to report the number of CRS-related antibiotics and oral corticosteroids used in the last 3 months. CRS symptom burden was measured using the 22-item Sino-Nasal Outcome Test (SNOT-22). Associations were sought between CRS-related antibiotics and oral corticosteroids use at follow-up compared to enrollment. RESULTS: From enrollment to follow-up, the mean number of CRS-related antibiotics courses used decreased by 0.2 courses (95% confidence interval [CI]: 0.1-0.4, P = .012), and the mean number of CRS-related oral corticosteroid courses used also decreased by 0.2 courses (95% CI: 0.1-0.3, P = .029). The number of CRS-related antibiotics used at follow-up was associated with CRS-related antibiotic use at enrollment (adjusted rate ratio [RR] = 1.58, 95% CI: 1.17-2.13, P = .003). The number of CRS-related oral corticosteroids used at follow-up was associated with reported CRS-related oral corticosteroid use at enrollment (adjusted RR = 3.20, 95% CI: 1.69-6.07, P < .001). SNOT-22 results at enrollment were also not predictive of future systemic medication use. CONCLUSIONS: Appropriate medical management of CRS is associated with decreased use of oral antibiotics and corticosteroids. Previous utilization of antibiotics and oral corticosteroids for CRS is associated with future use of these medications. LEVEL OF EVIDENCE: 2c Laryngoscope, 2019.

Clinical Traits Characterizing an Exacerbation-Prone Phenotype in Chronic Rhinosinusitis.

OBJECTIVE: Acute exacerbation of chronic rhinosinusitis (AECRS) is associated with significant quality-of-life decreases. We sought to determine characteristics associated with an exacerbation-prone phenotype in chronic rhinosinusitis (CRS). STUDY DESIGN: Cross-sectional. SETTING: Tertiary care rhinology clinic. SUBJECTS: Patients with CRS (N = 209). METHODS: Patient-reported number of sinus infections, CRS-related antibiotics, and CRS-related oral corticosteroids taken in the last 12 months were used as metrics for AECRS frequency. Sinonasal symptom burden was assessed with the 22-item Sinonasal Outcome Test (SNOT-22). Ninety patients reporting 0 for all AECRS metrics were considered to have had no AECRS in the prior 12 months. A total of 119 patients reported >3 on at least 1 AECRS metric and were considered as having an exacerbation-prone phenotype. Characteristics associated with patients with an exacerbation-prone phenotype were identified with exploratory regression analysis. RESULTS: An exacerbation-prone phenotype was positively associated with comorbid asthma (adjusted odds ratio [ORadj] = 3.68, 95% CI: 1.42-9.50, P = .007) and SNOT-22 (ORadj = 1.06, 95% CI: 1.04-1.09, P < .001). Polyps were negatively associated (ORadj = 0.27, 95% CI: 0.11-0.68, P = .005) with an exacerbation-prone phenotype. SNOT-22 score ≥24 identified patients with an exacerbation-prone phenotype with a sensitivity of 93.3% and a specificity of 57.8%. Having either a SNOT-22 score ≥24 with a nasal subdomain score ≥12 or a SNOT-22 score ≥24 with an ear/facial discomfort subdomain score ≥3 provided >80% sensitivity and specificity for detecting patients prone to exacerbation. CONCLUSIONS: In total, these results point to a CRS exacerbation-prone phenotype characterized by high sinonasal disease burden with comorbid asthma but interestingly without polyps.

Treatment history and association between allergic rhinitis symptoms and quality of life.

BACKGROUND: Recalcitrance of allergic rhinitis (AR) to medical management may be reflective of patient-specific impact of AR symptoms. AIMS: To understand the relationship between AR symptoms and general health-related quality of life (QOL) or AR control, based on treatment status. METHODS: Cross-sectional cohort study of 130 adult participants-65 using no allergy medications and 65 consistently using intranasal corticosteroid sprays (ICS) in the last 3 months-presenting with persistent AR. General health-related QOL was measured using the EuroQol 5-dimensional visual analog scale (EQ-5D VAS). Severity and control of AR symptoms were measured using the 22-item Sinonasal Outcome Test (SNOT-22) and the Rhinitis Control Assessment Test (RCAT), respectively. We compared associations between AR symptoms and general health-related QOL and AR control in patients presenting with persistent AR with and without ICS use. RESULTS: Severity of AR symptoms was similar between cohorts. In participants using no allergy medications, extranasal AR symptom severities were most dominantly associated with decreased EQ-5D VAS and RCAT score. In participants using ICS, only nasal symptom severities were associated with decreased EQ-5D VAS and RCAT scores. Consistently, only in participants on ICS was a deviated septum associated with decreased EQ-5D VAS (ß = - 12.1, 95% CI - 21.1 to - 3.1, p = 0.011) and poorly controlled AR (OR = 4.27, 96% CI 1.27 to 14.33; p = 0.019). CONCLUSIONS: In persistent AR despite consistent ICS use, nasal symptoms may be the dominant drivers of AR-associated decreased general health-related QOL in contrast to persistent AR on no medication, when extranasal symptoms of AR are most significant. Longitudinal study is needed to investigate whether these results are predictive of responsiveness to ICS.

Determinants of noticeable symptom improvement despite sub-MCID change in SNOT-22 score after treatment for chronic rhinosinusitis.

BACKGROUND: The minimal clinically important difference (MCID) of the 22-item Sino-Nasal Outcome Test (SNOT-22) is specific but not sensitive for identifying patients experiencing noticeable improvement in symptoms of chronic rhinosinusitis (CRS). It is unclear why some patients with less than 1 MCID change in SNOT-22 score nevertheless report noticeable improvement in their CRS symptoms. METHODS: This investigation was a retrospective study of 247 CRS patients undergoing medical management who completed SNOT-22 surveys in 2 consecutive visits 2-12 months apart. The validated nasal, sleep, ear/facial discomfort, and emotional SNOT-22 subdomain scores were calculated. At the second visit, patients reported their global change in CRS symptoms on a 5-item transition rating scale as: "Much worse"; "A little worse"; "About the same"; "A little better"; or "Much better." Patient-reported improvement in symptoms (at least "A little better") was tested for association with changes in SNOT-22 subdomain scores. RESULTS: In the entire cohort, patient-reported improvement in CRS symptoms was associated with improvement in all SNOT-22 subdomain scores (p < 0.001). In patients with less than 1 MCID (12 points) of change in the SNOT-22, only the nasal subdomain (adjusted odds ratio, 0.89; 95% confidence interval [CI], 0.79-0.99; p = 0.042) was associated with patient-reported improvement in CRS symptoms. Changes in none of the other SNOT-22 subdomain scores were associated with patient-reported improvement in CRS symptoms. CONCLUSIONS: Among patients with less than 1 MCID change in the SNOT-22, improvement in only nasal symptoms-but not extranasal symptoms-of CRS is associated with those who nevertheless report improvement of their CRS symptoms.

Differential perception and tolerance of chronic rhinosinusitis symptoms as a confounder of gender-disparate disease burden.

BACKGROUND: Previous studies have consistently shown that females with chronic rhinosinusitis (CRS) have a greater CRS symptom burden than males with CRS. Our objective was to determine whether differential disease perception could explain this phenomenon. METHODS: A total of 500 participants (239 males, 261 females) with CRS were recruited. CRS symptom burden was assessed with the 22-item Sino-Nasal Outcome Test (SNOT-22). General health-related quality of life was assessed with the visual analog scale of the 5-dimensional EuroQol questionnaire (EQ-5D VAS). Participants were asked to rate their CRS symptom control as "Not at all," "A little," "Somewhat," "Very," and "Completely." "Not at all," "A little," and "Somewhat" controlled symptoms were considered to reflect poorly controlled symptoms. RESULTS: SNOT-22 score was significantly more severe (p < 0.001) among females (mean, 44.0; standard deviation [SD], 22.5) than males (mean, 36.3; SD, 20.2). However, there was no significant difference in male- vs female-reported CRS symptom control (p = 0.154). In addition, there was no significant difference (p = 0.109) in EQ-5D VAS score between males (mean, 70.9; SD, 19.0) and females (mean, 68.4; SD, 19.5). Although a SNOT-22 score of ≥25 was predictive of poorly controlled symptoms in males (sensitivity, 82.6%; specificity, 62.5%), a SNOT-22 score of ≥30 was predictive of poorly controlled symptoms in women (sensitivity, 82.4%; specificity, 64.5%). CONCLUSION: Females with CRS reported more severe SNOT-22 scores, despite reporting a similar level of symptom control and general health-related quality of life as men. Women had a higher SNOT-22 threshold for poorly controlled symptoms. Female CRS patients may have greater perception and tolerance of CRS symptoms without a corresponding significant, disparate downstream impairment.

Chronic rhinosinusitis control from the patient and physician perspectives.

OBJECTIVES: The concept of disease control incorporates independent disease characteristics that are longitudinally reflective of disease status and which can be used to make treatment decisions. Chronic rhinosinusitis (CRS) is a chronic condition for which the determination of disease control by both the patient and the treating physician is important. Our objectives were to determine CRS disease characteristics that are associated with patient-reported and physician-rated CRS disease control. STUDY TYPE: Cross-sectional. METHODS: A total of 209 participants were prospectively recruited. Participants were asked to rate their global level of CRS control as "not at all," "a little," "somewhat," "very," and "completely." All participants completed a 22-item Sinonasal Outcome Test (SNOT-22) and also reported the number of sinus infections, CRS-related antibiotic courses taken, CRS-related oral corticosteroid courses taken, and missed days of work or school due to CRS, all in the last 3 months. Clinical and demographic characteristics were also collected from each participant. A Lund-Kennedy endoscopy score was calculated for each participant from nasal endoscopy. Two rhinologists were then given each participant's SNOT-22 score (as well as SNOT-22 nasal, sleep, otologic/facial pain, and emotional subdomain scores), endoscopy score, and the number of sinus infections, CRS-related antibiotics, CRS-related oral corticosteroid courses and missed days of work or school due to CRS in the preceding 3 months as reported by the patient. The two rhinologists were blinded to all other participant characteristics and each rhinologist independently rated every participant's global control level as "not at all," "a little," "somewhat," "very," and "completely." Associations were sought between CRS disease characteristics (SNOT-22 score, endoscopy score, sinus infections, CRS-related antibiotic usage, CRS-related oral corticosteroid usage, and lost productivity due to CRS) and patient-reported CRS control as well as mean physician-rated CRS control. RESULTS: Patient-reported global CRS control was associated only with SNOT-22 (adjusted relative risk [RR] = 0.99, 95% CI: 0.98-0.99, P < .001) but no other CRS disease characteristic. Patient-reported CRS control was specifically associated only with nasal symptoms and not extra-nasal symptoms of CRS. Physician-rated CRS control was associated with SNOT-22 score (adjusted RR [for each 1-unit increase of SNOT-22] = 0.99, 95% CI: 0.98-0.99, P < .001), number of acute bacterial CRS exacerbations-reflected by number of antibiotic courses taken (or sinus infections)-in the last 3 months (adjusted RR = 0.89, 95% CI: 0.82-0.98, P = .014) and the number of CRS-related oral corticosteroid courses taken in the last 3 months (adjusted RR = 0.87, 95% CI: 0.78-0.97, P = .012). Nasal, sleep, and otologic/facial pain symptoms were all associated with physician-rated CRS control. Having used at least one course of antibiotics or oral corticosteroids in the last 3 months was the optimal threshold for detecting poorly controlled CRS. CONCLUSIONS: Patients and physicians use different criteria to determine the level of CRS control. While both rely on the burden of CRS symptomatology, patients consider primarily nasal symptoms while physicians include nasal and extra-nasal symptoms of CRS in determining CRS control. Physicians also independently consider CRS-related antibiotic use, as a reflection of acute bacterial CRS exacerbations, and CRS-related oral corticosteroid use in the determination of global CRS control.

Relationship between chronic rhinosinusitis exacerbation frequency and asthma control.

OBJECTIVES/HYPOTHESIS: To determine the association between the frequency of acute chronic rhinosinusitis (CRS) exacerbations (AECRS) and the degree of asthma control in asthmatic CRS patients. STUDY DESIGN: Cross-sectional study. METHODS: We prospectively recruited 108 asthmatic CRS patients as participants. Asthma control was assessed using the Asthma Control Test (ACT). The frequency of AECRS was assessed using three previously described indirect metrics for AECRS: the frequency of patient-reported sinus infections, CRS-related antibiotics use, and CRS-related oral corticosteroids use in the last 3 months. CRS symptom severity was measured using the 22-item Sinonasal Outcome Test (SNOT-22). Associations between ACT score and metrics for AECRS were performed using linear regression while controlling for clinical and demographic characteristics, including SNOT-22 score. RESULTS: ACT score was significantly and negatively associated with the frequency of patient-reported sinus infections (adjusted linear regression coefficient [ß] = -1.2, 95% confidence interval [CI]: -2.3 to -0.1, P = .033), CRS-related antibiotics courses (adjusted ß = -1.4, 95% CI: -2.3 to -0.5, P = .004), and CRS-related oral corticosteroid courses (adjusted ß = -1.5, 95% CI: -2.5 to -0.5, P = .004) in the last 3 months, independent of characteristics including SNOT-22 score. Poor asthma control could be detected using one or more sinus infections (70.6% sensitivity, 47.3% specificity), CRS-related antibiotics (50.0% sensitivity, 73.0% specificity), or CRS-related oral corticosteroids (58.8% sensitivity, 71.6% specificity) in the last 3 months. CONCLUSIONS: AECRS are negatively associated with the level of asthma control in asthmatic CRS patients, independent of CRS symptom severity. These results highlight AECRS as a distinct clinical manifestation of CRS that should be routinely assessed in CRS patients. LEVEL OF EVIDENCE: 2c. Laryngoscope, 128:1033-1038, 2018.

Association between Asthma and Chronic Rhinosinusitis Severity in the Context of Asthma Control.

Objective Comorbid asthma is associated with decreased quality of life (QOL) in chronic rhinosinusitis (CRS). It is unclear whether this association is independent of the patients' clinical asthma status. We therefore sought to determine if asthma is associated with lower QOL in CRS, independent of asthma control. Study Design Cross-sectional cohort study of 350 patients with CRS. Setting Tertiary academic rhinology clinic. Subjects and Methods In total, 350 participants with CRS were recruited and 28.3% were asthmatic. CRS-specific QOL was measured using the 22-item Sinonasal Outcome Test (SNOT-22). Asthma control was assessed with the Asthma Control Test (ACT). General health-related QOL was assessed with the EuroQoL 5-dimensional general health-related quality of life survey visual analog scale (EQ-5D VAS). Associations were sought between SNOT-22 and EQ-5D VAS (dependent variables) and asthma (independent variable), while controlling for ACT. ACT score for patients with CRS without asthma was set at 25 (indicating completely controlled, asymptomatic asthma). Results Comorbid asthma was associated with SNOT-22 (ß = 11.8; 95% confidence interval [CI], 6.2-17.3; P < .001) and EQ-5D VAS (ß = -6.2; 95% CI, -11.2 to -1.3; P = .014). After controlling for ACT, asthma was no longer associated with SNOT-22 ( P = .147) or EQ-5D VAS ( P = .994). Instead, ACT score was associated with SNOT-22 (ß = -2.1; 95% CI, -3.2 to -1.1; P < .001) and EQ-5D VAS (ß = 2.1; 95% CI, 1.1 to 3.0; P < .001). ACT score completely drove the association between asthma and worse QOL. Conclusion Comorbid asthma is not necessarily reflective of decreased QOL in CRS. The association of comorbid asthma with lower QOL in CRS is related to the clinical status (eg, control) of asthma.

Association of Socioeconomic Status, Race and Insurance Status with Chronic Rhinosinusitis Patient-Reported Outcome Measures.

Objective Disparities in health and health care access are widely prevalent. However, disparities among patients with chronic rhinosinusitis (CRS) are poorly understood. We investigated if CRS severity at presentation according to socioeconomic factors. Study Design Cross-sectional study. Setting Tertiary rhinology center. Subjects and Methods Three hundred prospectively recruited patients presenting with CRS were included. Outcome variables included CRS symptomatology, as reflected by the 22-item Sinonasal Outcome Test (SNOT-22); general health status, as reflected by the EuroQol 5-dimensional visual analog scale (EQ-5D VAS); and CRS-related antibiotic and systemic corticosteroid use. Race/ethnicity, zip code income bracket, education level, and insurance status were used as predictor variables. Regression, controlling for clinical and demographic characteristics, was used to determine associations between predictor and outcome variables. Results Mean SNOT-22 score was 33.8 (SD, 23.2), and mean EQ-5D VAS score was 74.2 (SD, 18.9). On multivariable analysis, presenting SNOT-22 and EQ-5D VAS scores were not associated with nonwhite patient race/ethnicity ( P = .634 and P = .866), education ( P = .106 and P = .586), or the percentage of households in zip code with incomes <$50,000 per year ( P = .917 and P = .979, respectively). SNOT-22 scores did not differ by insurance type, but patients receiving Medicare reported worse general health status. Use of oral antibiotics or oral steroids for CRS was not associated with predictor variables. Conclusion Patients with CRS presented to a tertiary rhinology center with similar metrics for CRS severity and pre-presentation medical management regardless of race/ethnicity, education status, or zip code income level. Patients with Medicare had worse general health status. Further research should investigate potential disparities in diagnosis of CRS, specialist referral, and treatment outcomes.

Utilization patterns of systemic corticosteroid use for chronic rhinosinusitis.

OBJECTIVE: We sought to characterize the utilization pattern and factors associated with use of systemic corticosteroids for CRS. METHODS: This was a cross-sectional study of 236 participants with CRS who were prospectively recruited. Participants reported the number of CRS-related oral corticosteroid courses taken in the last year. Baseline CRS symptomatology was measured using the 22-item Sinonasal Outcome Test (SNOT-22) and SNOT-22 sleep, nasal, otologic/facial pain and emotional subdomain scores. Clinical and demographic characteristics were also collected. Association was determined between patient characteristics and oral corticosteroid use in the last year for CRS. RESULTS: Sleep (p = .026), nasal (p < .001) and otologic/facial pain (p = .022) SNOT-22 subdomain scores, and nasal polyps (p = .007) were associated with CRS-related oral corticosteroid use. In study participants without polyps, past CRS-related oral corticosteroid use was associated with sleep (adjusted OR = 1.56, 95%CI: 1.01-2.40, p = .043), otologic/facial pain (adjusted OR = 1.65, 95%CI: 1.09-2.51, p = .019) and nasal subdomain scores (adjusted OR = 1.59, 95%CI: 1.01-2.51, p = .047). In study participants with polyps, past CRS-related oral corticosteroid use was only associated with the nasal subdomain score (adjusted OR = 2.20, 95%CI: 1.40-3.45, p = .001). CONCLUSIONS: Past CRS-related oral corticosteroid use was associated with increased baseline severity of specific symptoms, which were different depending on the presence of polyps.

Association between systemic antibiotic and corticosteroid use for chronic rhinosinusitis and quality of life.

OBJECTIVE: We sought to establish the significance of querying chronic rhinosinusitis (CRS) patients about their past CRS-related oral antibiotic and corticosteroid usage by determining the association between these metrics and patients' quality of life (QoL). STUDY DESIGN: Cross-sectional study. METHODS: A total of 157 patients with CRS were prospectively recruited. CRS-specific QoL was measured using the 22-item Sinonasal Outcome Test (SNOT-22). General health-related QoL was measured using the EuroQoL five-dimensional questionnaire visual analog scale. Associations were sought between these measures of QoL and frequency of CRS-related oral antibiotic and corticosteroid usage reported by the participants in the prior 3 and 12 months. RESULTS: More frequent antibiotic and corticosteroid use was significantly associated with worse CRS-specific and general health-related QoL, whether querying medication use over the prior 3 months or over the prior 12 months (P < 0.001 in all cases). The effect size of CRS-related antibiotic use during the prior 3 months on CRS-specific QoL (SNOT-22 score) was significantly greater than for use during the prior 12 months. However, there was no other statistically significant difference in effect size for association between QoL and CRS-related antibiotic or corticosteroid use in the prior 3 months versus prior 12 months. These results were independent of the presence or absence of polyps. CONCLUSION: More frequent past CRS-related oral antibiotic and corticosteroid use, regardless of time period queried (3 months or 12 months) is associated with significant decrease in CRS-specific and general health-related QoL. CRS-related systemic medication use is an important indicator of CRS patients' QOL that easily can be queried and utilized in both clinical and research settings. LEVEL OF EVIDENCE: 2c.
