Otolaryngologists adhere to evidence-based guidelines for chronic rhinosinusitis

Chronic rhinosinusitis: microbiology and treatment of acute exacerbations in patients after endoscopic surgery

Objective

Antibiotics are the mainstay of therapy for acute exacerbation of chronic rhinosinusitis. However, no treatment guidelines exist. Most clinicians follow the recommendations for acute bacterial rhinosinusitis, usually caused by Haemophilus influenzae, Streptococcus pneumoniae or Moraxella catarrhalis, and treat with amoxicillin or amoxicillin-clavulanate.

Method

Medical data of 810 patients who had undergone endoscopic sinus surgery were analysed retrospectively. The results of bacterial cultures and treatment course were assessed in 152 patients who presented with acute exacerbation of chronic rhinosinusitis within 6 months of endoscopic sinus surgery.

Results

The most common bacterial species present were Staphylococcus aureus (36 per cent), Pseudomonas aeruginosa (13 per cent) and Escherichia coli (11 per cent). Most of the isolates showed resistance or intermediate sensitivity to amoxicillin-clavulanate. Targeted antibiotic therapy was significantly more effective than empiric therapy (71 per cent versus 42 per cent). The most effective antibiotics were fluoroquinolones.

Conclusion

Acute exacerbation of chronic rhinosinusitis shows different microbiology than acute bacterial rhinosinusitis and requires a different therapeutic approach. It is optimally treated with culture-directed antibiotic therapy.

Financial and Intellectual Conflicts of Interest Among Japanese Clinical Practice Guidelines Authors for Allergic Rhinitis

OBJECTIVE

To elucidate financial and intellectual conflicts of interest (COIs) among clinical practice guideline (CPG) authors of allergic rhinitis in Japan and to evaluate the extent of transparency and accuracy in COIs by CPG authors of allergic rhinitis.

STUDY DESIGN

A cross-sectional analysis of the payment data from all 79 pharmaceutical companies in Japan between 2016 and 2017.

SETTING

Japan.

METHODS

We considered all 27 CPG authors from 2 different versions of the most prominent CPGs for allergic rhinitis in Japan. Using payment data disclosed by 79 major pharmaceutical companies between 2016 and 2017, we assessed the magnitude and characteristics of financial COIs of CPG authors. We also evaluated the intellectual COIs of the CPG authors by counting self-citations of research articles related to CPG statements and recommendations.

RESULTS

Of 27 CPG authors, 26 authors (96.3%) received at least 1 payment from a combined total of $1,333,552 between 2016 and 2017. The 2-year combined average and median monetary values per author were $49,391 (SD, $67,438) and $18,400 (interquartile range: $6,216-$72,494), respectively. Pharmaceutical companies with novel drugs predominantly made these payments. The percentage of citations with at least 1 CPG author relative to total citations was 47.6% in 2016 and 27.9% in 2020. There were no formal COI disclosure statements in either version.

CONCLUSION

This study found that allergic rhinitis CPG authors had significant financial relationships with pharmaceutical companies, particularly those marketing novel drugs. In addition, CPG authors had relatively high self-citation rates, a potential marker of intellectual COIs. More rigorous and comprehensive COI management strategies are needed.

Olfactory Performance among Hospital Residents

Introduction  Smell plays an important role in the maintenance of health and quality of life of the general population. Health workers with olfactory impairment may not be able to help diagnose certain diseases, and subsequently increase the risk of hazardous events and mortality among those affected. ‘Odor learning’ requires repeated experiences with different smells to develop a discriminatory ability, and this is a process that takes years. Because of that, physicians of certain medical specialities have better odor detection than others.

Objective  To study the olfactory performance and associated factors of otorhinolaryngology residents compared with residents of different medical specialities in a representative sample of a tertiary hospital.

Methods  The University of Pennsylvania Smell Identification Test (UPSIT) was used to compare olfactory performance. Clinical and epidemiological data were collected among 42 hospital residents.

Results  Otorhinolaryngology residents presented an average UPSIT score of 35.0, and the other residents, a score of 32.8 ( p  = 0.02) Of all the residents, 40.5% showed some grade of olfactory impairment. Half of the females students in the first year of residency showed olfactory dysfunction. The multivariate analyses found age ( p  = 0.03; 95% confidence interval for β = 0.33) to be an independent predictor of the UPSIT score.

Conclusion  The present study demonstrated that otorhinolaryngology residents have greater olfactory capacity compared with other residents. Future studies should explore the relevant factors of olfactory impairment and its impact on quality of life in this population.

Healthcare utilisation, follow-up of guidelines and practice variation on rhinosinusitis in adults: A healthcare reimbursement claims study in The Netherlands

Objectives

To provide insight into healthcare utilisation of rhinosinusitis, compare data with clinical practice guideline recommendations and assess practice variation.

Design

Anonymised data from claims reimbursement registries of healthcare insurers were analysed, from 1 January 2016 until 31 December 2016.

Setting

Secondary and tertiary care in the Netherlands.

Participants

Patients ≥18 years with diagnostic code “sinusitis.”

Main outcome measures

Healthcare utilisation (prevalence, co‐morbidity, diagnostic testing, surgery), costs, comparison with guideline recommendation, practice variation.

Results

We identified 56 825 patients, prevalence was 0.4%. Costs were € 45 979 554—that is 0.2% of total hospital‐related care costs (€21 831.3 × 10⁶). Most patients were <75 years, with a slight female preponderance. 29% had comorbidities (usually COPD/asthma). 9% underwent skin prick testing, 61% nasal endoscopy, 2% X‐ray and 51% CT. Surgery rate was 16%, mostly in daycare. Nearly, all surgical procedures were performed endonasally and concerned the maxillary and/or ethmoid sinus. Seven recommendations (25%) could be (partially) compared to the distribution of claims data. Except for endoscopy, healthcare utilisation patterns were in line with guideline recommendations. We compared results for three geographical regions and found generally corresponding rates of diagnostic testing and surgery.

Conclusion

Prevalence was lower than reported previously. Within the boundaries of guideline recommendations, we encountered acceptable variation in healthcare utilisation in Dutch hospitals. Health reimbursement claims data can provide insight into healthcare utilisation, but they do not allow evaluation of the quality and outcomes of care, and therefore, results should be interpreted with caution.
