NEW YORK--(BUSINESS WIRE)--Week three data of the Barometer study from 4016 physicians in 30 countries conducted by Sermo reveals the emergence of treatment patterns and efficacy perceptions. Sermo, the largest global healthcare polling company and social platform for physicians, has published unrestricted access to the results of its Real Time Barometer study on sermo.com.

Key findings:

In Wave 3 we explored perceptions of physicians who were high vs moderate vs low treaters of COVID patients. The total number of physician respondents for Wave 3 was 4016. Of those, 33% treated COVID patients (n=1337).

The COVID treaters (1337) breakdown was:

42% of COVID treaters have treated between 1-5 patients

20% of COVID treaters have treated between 6 -10 patients

38% of COVID treaters have treated between 11 and more patients

We did not find significant differences between highly active and low active COVID treaters in the below findings.

Usage patterns among COVID treaters (N= 1337)

The top three treatments that doctors reported having prescribed were Azithromycin (58%), Hydroxychloroquine (50%), and Bronchodilators (48%); traditional Chinese medicine has been used by 67% of physicians in China.

Week over week increases in usage

Percentage of physicians in New York who have used Hydroxychloroquine nearly doubled since Wave 1 week of March 25 (23% to 40% to 43% wave over wave).

Italy and France had the highest increase in COVID treaters having prescribed Hydroxychloroquine wave over wave; an increase from 50% to 83% for Italy and an increase from 20% to 50% for France.

The number of COVID treaters that report having used Hydroxychloroquine and Azithromycin both increased 17% points since Wave 1 the week of March 25. Hydroxychloroquine Wave 1: 33%, Wave 2: 44%, Wave 3: 50% Azithromycin Wave 1: 41%, Wave 2: 50%, Wave 3: 58%

The number of COVID treaters that report having used Bronchodilators increased 12% points (from 36% to 48%) week over week.

Usage of anti-HIV drugs (e.g. Lopinavir plus Ritonavir), drugs to treat the flu (e.g. Oseltamivir), and plasma from recovered patients remains steady week over week, while use of non-approved drugs (e.g. Remdesivir) decreased slightly.

Perceived treatment efficacy

Physicians who treat COVID patients in Italy, Spain, France, and China have higher perceptions of Hydroxychloroquine’s efficacy vs the US (~50% vs 29%).

The top treatments that have been used/seen used and reported as very or extremely effective among COVID treaters (N= 1337) include: 46% plasma from recovered patients (n=363); 40% Hydroxychloroquine (n=875); 38% high dose steroids during a cytokine storm (n=556) No significant differences of perceived efficacy were observed between highly active COVID treaters and users of these drugs (physicians treating 11+ patients) and lower active COVID treaters (1-10 patients) 55% of physicians in China who have used traditional Chinese medicine rated traditional Chinese medicine as effective or extremely effective



Most popular Hydroxychloroquine dosage regimen

75% report using 400mg BID on day one (800mg total), then 400 mg daily for 4-5 days

10% report using 600mg BID on day one (1,200mg total), then 400 mg daily for 4 days

Most results are reported for individual countries with a minimum sample size of 250. A sample size of 250 point estimates have a precision of a +/- 6% precision at a 94% confidence level. Where sample sizes are smaller, N sizes are noted. Thirty countries included in the study are the United States, Canada, Argentina, Brazil, Mexico, Germany, Italy, the United Kingdom, France, Spain, Belgium, the Netherlands, Sweden, Turkey, Poland, Russia, Finland, Ireland, Switzerland, Austria, Denmark, Norway, Greece, Taiwan, Japan, South Korea, Australia, China, India, and Hong Kong.
