Clinical Trial Summary

Chronic rhinosinusitis presents with a plethora of symptoms including non-rhinologic symptoms such as depression, sleep disturbances & the more recently recognized cognitive dysfunction. It has recently been identified that sinus specific treatments such as endoscopic sinus surgery can improve cognitive outcomes in patients with cognitive deficit secondary to chronic inflammation in the upper and lower airway. However, it remains to be seen whether or not offering surgery to these patients at an earlier date has an impact on the degree of improvement on cognitive function in comparison to patients who have to wait long periods for their treatment.

Description:

Purpose To compare the improvement in cognitive deficit after medical management and surgical management in the treatment of Chronic Rhinosinusitis.

Hypothesis Cognitive deficit secondary to chronic rhinosinusitis will show a greater improvement with surgical management when compared to medical management.

Cognitive deficit secondary to chronic rhinosinusitis will improve quicker postoperatively for patients offered endoscopic sinus surgery earlier than for those who are placed on long waitlists for surgery

Study Design:

This is a prospective cohort series to be conducted at the St. Paul's Sinus Centre. All patients recruited into the study would have been diagnosed with chronic rhinosinusitis and will be subjected to appropriate and standardized medical management. They will be subjected to surgical management if they are not completely relieved of their symptoms. Prior to medical or surgical management, they will be subjected to the modified mini mental state examination to assess their baseline and post treatment (medical and surgical) cognitive function.

Data storage and safeguards The data will be stored on a password protected computer at St. Paul's Hospital in the Department of Otolaryngology on an encrypted Microsoft excel spreadsheet. The computer containing study data will be password-protected for access only by the principal investigator, co-investigator and study coordinator stored in a locked office, and backed-up remotely on to a secured hospital server. All hard copy documents will be kept in binders, in the Principal Investigator's office in a locked cabinet.

Patients participating in the study will all be assigned random study ID numbers. The study code is not derived from or related to the information about the individual, i.e., name, SIN, PHN, hospital number, DOB, address, or unique characteristic. These numbers will be used on all study documentation. Participant names are being stored separately from study data in a master list with the study ID numbers.

Data Monitoring Patients will continue to be assessed at routine follow up visits. Statistics will be completed after the study is complete on its objectives. Data will be also monitored on a continuous basis.

Statistical Analysis

Descriptive statistics will be used to summarize all demographic data, comorbidities, and adverse effects reported by the patients. Paired student t-tests will be applied to investigate the difference between the mean 3M Examination scores, MLK scores, SNOT-22 scores, before commencement of each treatment arm and subsequent MLK scores, SNOT-22 scores after treatment is complete. A running total of the treatment costs for each patient will be maintained. One way Anova test will be applied to investigate the difference between the mean costs for each treatment arm. Probability values less than 0.05 will be considered statistically significant.

Patients that will undergo endoscopic sinus surgery though the private system. Beforehand they could of used medical management including, budesonide for their symptoms.
• Public system endoscopic sinus surgery
Patients that undergo endoscopic sinus surgery though the public system after waiting for at least 1 year. Beforehand they could of used medical management, including budesonide for their symptoms.

Drug:
• Budesonide
Patients will receive medical management for their symptoms that will consist of topical nasal steroid, budesonide and any other required medication for their disease.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Modified mini mental state examination	This short test consists of questions to assess memory which will take 5-10 minutes to complete.	Before starting medical or surgical management and then 6 months after
Secondary	Change in Cognitive failures Questionnaire	This includes 25 questions for patients to self-report everyday errors of perception, memory and motor functioning. It is scored out of 100 with higher score indicating worse more cognitive failures.	Before starting medical or surgical management and then 6 months after
Secondary	Change in Sino-nasal Outcome Test-22 (SNOT-22) scores:	This is a standard of care form that includes 22 questions about symptoms and social/emotional consequences of participants nasal disorder. Participants will be asked to rate their problems based on the past two weeks. The questionnaire is out of 110 points with higher score indicating worse symptoms.	Before starting medical or surgical management and then 6 months after
Secondary	Change in Nasal endoscopy	This is standard-of-care at St. Paul's Sinus Centre. Participants sinuses will be examined using an instrument called an endoscope which is a metal rod with a camera attached at the end. During the sinus examination, pictures and scores of the sinuses will be recorded. Endoscopic score are given from 0-2 based on endoscopic evidence of polyps, edema and discharge. A higher score indicates worse symptoms.	Before starting medical or surgical management and then 6 months after
