Use of the modified SNOT-16 in primary care patients with clinically diagnosed acute rhinosinusitis.

ABSTRACT:

Objective

To determine the reliability, validity, responsiveness, and the minimal important difference (MID) for the Sinonasal Outcome Test-16 (SNOT-16) in the measurement of disease-specific quality of life (QOL) in adults with acute rhinosinusitis.

Study design

Randomized controlled trial to evaluate antibiotic treatment for acute rhinosinusitis.

Setting

Ten community practices in St Louis, Missouri.

Methods

The modified SNOT-16 was completed at baseline (by both face-to-face and telephone interviews) and by telephone interview at 3, 7, and 10 days by 166 adults with acute rhinosinusitis diagnosed clinically using standardized criteria (36% were male, 78% were white). Considering severity and frequency, patients rated how much they were bothered by each item using a 4-point scale. The mean SNOT-16 score (ranging from 0 [no problem] to 3 [large problem]) was compared with the patients' global assessment of change to evaluate responsiveness and the MID.

Results

The instrument was easy to use and took less than 5 minutes to complete. The SNOT-16 score identified statistically significant differences in the hypothesized direction for those reporting more or less severe symptoms (P = .02) and more or less bother (P < .001) demonstrating construct-related validity. The Cronbach α ranged from 0.82 to 0.91, demonstrating high internal consistency. There was a statistically significant decrease in scores with time (multivariate analysis of variance, P < .001). The effect sizes at days 3, 7, and 10 were 1.45, 2.34, and 2.90, respectively, indicating high sensitivity to clinical change. The MID was 0.5 units.

Conclusion

The modified SNOT-16 is a valid instrument to assess effectiveness of interventions to improve disease-specific QOL in adults with acute rhinosinusitis.

Project description:Objectives/hypothesisPrevious studies have shown declines in productivity due to chronic rhinosinusitis (CRS) are correlated with disease-specific quality-of-life (QOL) measures. However, it is unclear which symptom domains contribute primarily to productivity loss. This investigation sought to assess the association between CRS-specific QOL subdomain impairment and productivity loss.Study designProspective, multi-institutional, observational cohort study.MethodsThere were 198 patients with refractory CRS enrolled between August 2012 and June 2015. Baseline QOL measures were obtained across five subdomains of the 22-item SinoNasal Outcome Test (SNOT-22). Lost productivity time was determined from patient-reported measures of annual absenteeism, presenteeism, and lost leisure time, and then monetized using annual daily wage rates from the 2012 US National Census and 2013 Department of Labor statistics.ResultsProductivity losses correlated with impairments in both SNOT-22 psychological dysfunction (Spearman correlation coefficient [Rs] = 0.428, P < .001), and sleep dysfunction domain scores (Rs = 0.355, P < .001). Higher SNOT-22 total scores also significantly correlated with increased monetized productivity losses (Rs = 0.366, P < .001). The mean annual productivity cost was $11,820/patient, whereas patients with comorbid immunodeficiency ($23,285/patient), tobacco use ($23,195/patient), and steroid dependency ($18,910/patient) reported higher than average annual productivity costs. Multivariate linear regression found maximum annual productivity costs in adjusted psychological ($13,300/patient, P < .001) and sleep dysfunction ($9,275/patient, P < .001) domains.ConclusionsImpairments in sleep and psychological SNOT-22 domains correlate with productivity losses. Patients with comorbid immunodeficiency, smoking, and steroid dependency had higher than average productivity losses. Targeted management of psychological and sleep dysfunction in combination with standard symptom control may improve patient-centered care and reduce the annual economic burden of CRS.Level of evidence2c.

Project description:BackgroundPrior study demonstrated that baseline 22-item Sino-Nasal Outcome Test (SNOT-22) aggregate scores accurately predict selection of surgical intervention in patients with chronic rhinosinusitis (CRS). Factor analysis of the SNOT-22 survey has identified five distinct domains that are differentially impacted by endoscopic sinus surgery (ESS). This study sought to quantify SNOT-22 domains in patient cohorts electing both surgical or medical management and postinterventional change in these domains.MethodsCRS patients were prospectively enrolled into a multi-institutional, observational cohort study. Subjects elected continued medical management or ESS. SNOT-22 domain scores at baseline were compared between treatment cohorts. Postintervention domain score changes were evaluated in subjects with at least six-month follow-up.ResultsA total of 363 subjects were enrolled with 72 (19.8%) electing continued medical management, whereas 291 (80.2%) elected ESS. Baseline SNOT-22 domain scores were comparable between treatment cohorts in sinus-specific domains (rhinologic, extranasal rhinologic, and ear/facial symptoms; p > 0.050); however, the surgical cohort reported significantly higher psychological (mean ± standard deviation [SD]: 16.0 ± 8.4 vs 12.0 ± 7.1; p < 0.001) and sleep dysfunction (13.7 ± 6.8 vs 10.5 ± 6.2; p < 0.001) than the medical cohort. Effect sizes for ESS varied across domains with rhinologic and extranasal rhinologic symptoms experiencing the greatest gains (1.067 and 0.997, respectively), whereas psychological and sleep dysfunction experiencing the smallest improvements (0.805 and 0.818, respectively). Patients experienced greater mean improvements after ESS in all domains compared to medical management (p < 0.001).ConclusionSubjects electing ESS report higher sleep and psychological dysfunction compared to medical management but have comparable sinus-specific symptoms. Subjects undergoing ESS experience greater gains compared to medical management across all domains; however, these gains are smallest in the psychological and sleep domains.

Project description:Objectives/hypothesisThe 22-item Sinonasal Outcome Test (SNOT-22) is a validated chronic rhinosinusitis health-related quality-of-life outcome (HRQoL) measure; however, SNOT-22 domains have not been validated specifically for chronic rhinosinusitis with nasal polyps (CRSwNP).Study designValidation of SNOT-22 domain structure, using data from 3 randomized, placebo-controlled, double-blinded, multicenter clinical trials of dupilumab in adults with moderate-to-severe CRSwNP.MethodsPreliminary dimensional structure was derived by exploratory factor analyses of SNOT-22 data from a phase 2 trial (NCT01920893) of dupilumab for the treatment of CRSwNP. Data from 2 phase 3 clinical trials (NCT02912468 and NCT02898454) were then used for confirmatory factor analysis, and evaluated for reliability, construct validity, and responsiveness. In all three trials, the SNOT-22 was administered electronically on a tablet and trial participants were required to answer all items.ResultsFactor analysis supported five domains: Nasal, Ear/Facial, Sleep, Function, and Emotion. Correlations between domains were moderate to high, ranging from 0.53 (Nasal-Emotion) to 0.88 (Function-Sleep). Construct validity was mostly supported; relationships with other measures were almost always in the intended direction and magnitude. Internal consistency reliability also confirmed questionnaire structure with strong Cronbach's alpha values (all >0.80). Moderate-to-high correlations were observed between change in SNOT-22 domain scores and other study patient-reported outcome measures, along with large effect-size estimates (≥0.7), demonstrating responsiveness of the Nasal, Sleep, and Function domains. Emotion and Ear/Facial domains had small-to-moderate effect sizes.ConclusionsPsychometric analyses support the validity, reliability, and responsiveness of five domains of SNOT-22 (Nasal, Ear/Facial, Sleep, Function, and Emotion) for assessing symptoms and impact on HRQoL in patients with CRSwNP.

Project description:IntroductionThis nationwide study builds on prior research, which suggests that Federally Qualified Health Centers (FQHCs) and other primary care providers are associated with increased access to opioid use disorder (OUD) treatment. We compare health care utilization, spending, and quality for Medicaid patients diagnosed with OUD who receive primary care at FQHCs and Medicaid patients who receive most primary care in other settings, such as physician offices (non-FQHCs). We hypothesized that the integrated care model of FQHCs would be associated with greater access to medication for opioid use disorder (MOUD) and/or behavioral health therapy and lower rates of potentially inappropriate co-prescribing.MethodsThis cross-sectional study examined 2012 Medicaid Analytic eXtract files for patients diagnosed with OUD receiving most (>50%) primary care at FQHCs (N = 37,142) versus non-FQHCs (N = 196,712) in all 50 states and Washington DC. We used propensity score overlap weighting to adjust for measurable confounding between patients who received care at FQHCs versus non-FQHCs and increase generalizability of findings given variation in Medicaid programs and substance use policies across states.ResultsFQHC patients displayed higher primary care utilization and fee-for-service spending, and similar or lower utilization and fee-for-service spending for other health service categories. Contrary to our hypotheses, non-FQHC patients were more likely to receive timely (≤90 days) MOUD (buprenorphine, methadone, naltrexone, or suboxone) (Relative Risk [RR] = 1.10, 95% CI: 1.07, 1.12) and more likely be retained in medication treatment (>180 days) (RR = 1.12, 95% CI: 1.09, 1.14). However, non-FQHC patients were less likely to receive behavioral health therapy (mental health or substance use therapy) (RR = 0.90, 95% CI: 0.88, 0.92) and less likely to remain in behavioral health treatment (RR = 0.92, 95% CI: 0.89, 0.94). Non-FQHC patients were more likely to fill potentially inappropriate prescriptions of benzodiazepines and opioids after OUD diagnosis (RR = 1.35, 95% CI: 1.30, 1.40).ConclusionsObserved patterns suggest that Medicaid patients diagnosed with OUD who obtained primary care at FQHCs received more integrated care compared to non-FQHC patients. Greater care integration may be associated with increased access to behavioral health therapy and quality of care (lower potentially inappropriate co-prescribing) but not necessarily greater access to MOUD.

Project description:ObjectivesThis study evaluates the enduring efficacy and patient satisfaction of dupilumab with interdose interval adjustments based on the Sino-Nasal Outcome Test (SNOT-22) in chronic rhinosinusitis with nasal polyps (CRSwNP).MethodsA retrospective analysis was conducted on 44 patients who had been treated with dupilumab for over 6 months. This study targeted individuals diagnosed with CRSwNP according to the 2020 edition of the European Position Paper on Rhinosinusitis and Nasal Polyps Criteria. The treatment involved an add-on dupilumab regimen, where the interdose interval was adjusted based on the SNOT-22 scores. Dosage adjustments were made such that patients with initial SNOT-22 scores greater than 40 were tapered to a target level of 20 or less. Similarly, for patients with initial scores of 40 or less, the treatment aimed for an improvement of 50% or more. At each visit, the effectiveness of the treatment was evaluated using SNOT-22, nasal polyp scores (NPS), and a subjective satisfaction questionnaire adapted from the Treatment Satisfaction Questionnaire for Medication (TSQM v.1.4).ResultsThe adjustment of the interdose interval for dupilumab based on SNOT-22 scores demonstrated sustained improvements in patients' subjective symptoms, satisfaction, and NPS. The mean (standard deviation) SNOT-22 scores significantly decreased from 46.04 (22.30) to 14.72 (13.66) over 6 months (P<0.001). Similarly, NPS scores improved from 3.20 (2.24) to 1.72 (1.46) within the same period (P<0.001). Satisfaction scores, ranging from 0 to 5, consistently remained above 3.5 for up to 6 months (P=0.166). Additionally, there was a significant correlation between the improvement in the nasal symptom domain of the SNOT-22 scores and higher satisfaction scores.ConclusionAdjusting dupilumab dosing intervals based on SNOT-22 scores from the outset resulted in sustained efficacy and patient satisfaction in Korean patients with CRSwNP. This approach will meaningfully assist clinicians in determining the optimal dupilumab dosing interval.
