Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate if using nasal irrigation, also known as nasal lavage, for 14 days after a positive test in high risk patients can reduce the severity of symptoms associated with COVID-19. Nasal lavage consists of running salt water in one nostril and out the other to get rid of germs. Nasal irrigation was done with either Betadine or baking soda to determine if adding an antimicrobial or changing the pH of the mucous helped. Hospitalization and death were compared for combined nasal irrigation groups to the CDC dataset of patients aged 50+

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to evaluate if using nasal irrigation, also known as nasal lavage, can reduce the severity of symptoms associated with COVID-19. Nasal lavage consists of running salt water in one nostril and out the other to get rid of germs. Saline nasal irrigation with Betadine or baking soda will be evaluated.

Participants will be asked to do several things during this study: watch a one minute video on YouTube, use a nasal irrigation device twice a day for 14 days, complete a one-time detailed survey and keep a research diary about their usage and symptoms using an on-line application called Qualtrics, agree to be texted reminders, be called on the phone if they fail to complete the daily diary two days in a row, agree to be called four times, and provide contact information for a secondary person who can be contacted if the primary participant is unavailable.

Participation in this study does not involve any significant risks. However, some people may find using nasal irrigation causes them some discomfort.

While there are no known benefits to participating in the study participants may see a reduction in their symptoms more quickly than if they didn't participate in the study.

Outcome Assessors
Hospitalization records were confirmed by study personnel blinded to participant status.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Betadine

Intervention - twice-a-day nasal lavage Twice-a-day virucidal group: Participants randomized to betadine will receive 2 gallon jugs of distilled water, two NeilMed Sinus Irrigation bottles and 28 salination packets (with some extras), OR one Navage unit with 28 SaltPods (and some extras), and a cardboard receptacle labeled "used saline containers" to keep track of adherence.

Those randomized to receive betadine will also receive one bottle of povidone-iodine, a one-sheet instruction with photographs demonstrating how to add ½ tsp betadine in addition to the salination packet to the sinus irrigation bottle or Navage unit reservoir prior to SaltPod, along with a ½ tsp measuring spoon.

Group Type OTHER

Nasal lavage

Intervention Type OTHER

Twice daily nasal lavage.

Baking Soda

Twice-a-day alkalinized group: Participants randomized to alkalinization will receive 2 gallon jugs of distilled water, two Neilmed bottles with 28 saline packets, OR one Navage unit with 28 SaltPods, and a cardboard receptacle labeled "used saline containers" to keep track of adherence. Those randomized to alkalinization will also receive a box of baking soda, ½ tsp measuring spoon and instructions on how to add the baking soda.
