Surgisphere Corporation, the company that supplied data for a controversial study on the health risks of hydroxychloroquine for COVID-19 patients published in The Lancet last week (May 22), has found itself in the spotlight after researchers raised questions about the dataset.
The Lancet study, which lists Surgisphere founder and CEO Sapan Desai as one of four coauthors, reported harmful effects tied to the anti-malaria drug hydroxychloroquine among patients with COVID-19. In response to the findings, the World Health Organization (WHO) and several other health organizations stopped or suspended clinical trials of the drug while they look more closely into the compound’s safety.
The database used for the Lancet study, which the paper states includes 96,032 patients from 671 hospitals across six continents, is accessible only by Surgisphere. But in the week since the paper’s publication, concerns about that dataset have swirled on social media, on the post-publication discussion website PubPeer, and in newspapers.
Initial concerns centered on the paper’s statistical analyses, as well as the fact that COVID-19 patient data were surprisingly homogeneous across continents, despite known differences in demographics and underlying health conditions in those populations. More-recent concerns have broadened to other aspects of the dataset. Desai has since acknowledged one error in an Australian cohort and yesterday published a brief correction. While he has said in an interview with The Scientist that he is looking into clearing up confusion around the study findings, Desai has continued to defend his work and the integrity of the Surgisphere data.
But that response has not assuaged the concerns of the scientific community. On May 28, an open letter, which has now accrued more than 180 signatories at research institutions around the world, laid out multiple other problems with the study data and analyses. In addition, readers of the study are beginning to ask about the nature and history of Surgisphere, and how it managed to obtain such a complex dataset in a relatively short period of time.
In explaining the decision to suspend hydroxychloroquine testing, WHO chief scientist Soumya Swaminathan said that although the Lancet data weren’t from a randomized controlled trial, the gold standard in clinical research, they “came from multiple registries and quite a large number of patients, 96,000 patients,” NPR reported earlier this week.
Concerns about the Lancet paper began appearing on blog posts and PubPeer soon after the study’s publication, however. Statisticians and medical scientists pointed to several peculiarities, including a lack of information about how observational data were adjusted during statistical analyses, and surprisingly high mortality rates in patients who received hydroxychloroquine—a drug that, while unproven as a treatment for COVID-19, has been in use in hospital settings for decades and had not shown such major negative effects in studies up until this point.
The profile of Surgisphere has risen dramatically during the COVID-19 pandemic.
The proportion of COVID-19 patients in Africa who were included in the dataset was also “rather high,” one PubPeer commenter noted: while 15,738 COVID-19 cases had been reported across the continent by the African Centers for Disease Control and Prevention as of April 14, the study claimed to have data—including detailed electronic health records—for 4,402 hospitalized patients up to this same date.
James Watson, a senior scientist at the Mahidol Oxford Tropical Medicine Research Unit in Thailand, says he has doubts that any research organization would have been able to obtain such detailed records for so many people in Africa so quickly. He outlined this and concerns about multiple other aspects of the study in the open letter, which includes 17 signatories based at institutions in Africa.
Based on healthcare workers’ descriptions of medical record-keeping at many hospitals in Africa, “I just find it very hard to believe,” Watson tells The Scientist. His unit suspended a just-launched trial of hydroxychloroquine following guidance from UK regulators shortly after the Lancet study was published.
Desai tells The Scientist that the high-quality hospital data in the publication result from Surgisphere working only with “top-tier institutions. . . . Naturally, this leads to the inclusion of institutions that have a tertiary care level of practice and provide quality health care that is relatively homogeneous around the world.”
A signatory on the open letter to The Lancet, Anthony Etyang, a consultant physician and clinical epidemiologist with the KEMRI-Wellcome Trust Research Programme in Kenya, writes to The Scientist that he too has doubts about the numbers of African patients in the dataset, adding that even private hospitals on the continent with top care often have poor medical records.
Study coauthors Mandeep Mehra, the medical director of the Brigham and Women’s Hospital Heart and Vascular Center, and Frank Ruschitzka of University Hospital Zurich did not respond to requests for comment.
In another development on May 28, The Guardian reported that researchers and journalists had been unable to verify the source of the Australian data included in the study. Surgisphere’s dataset included 73 deaths in Australia as of April 21, even though Johns Hopkins University, which has been tracking COVID-19 cases and deaths since the start of the outbreak, had counted just 67 by that point, the Guardian reported.
Desai explained the discrepancy to the Guardian by noting that a hospital in Asia had inadvertently been included in the Australian dataset. He has told media outlets that he cannot share the names of any of the hospitals involved in Surgisphere studies due to pre-arranged privacy deals with those hospitals, but adds in an interview with The Scientist that he’ll inquire if any hospitals are willing to voluntarily come forward to confirm their participation.
On May 29, Jessica Kleyn, a press officer at The Lancet journals, informed The Scientist in an emailed statement that the authors had corrected the Australian data in their paper and redone one of the tables in the supplementary information with raw data rather than the adjusted data Desai said had been shown before.
“The results and conclusions reported in the study remain unchanged,” Kleyn adds in the email. “The original full-text article will be updated on our website. The Lancet encourages scientific debate and will publish responses to the study, along with a response from the authors, in the journal in due course.”
Andrew Gelman, a statistician at Columbia University who has blogged about the article and started the PubPeer discussion on it, writes in an email to The Scientist that the authors’ update “does not address many of the questions that have been raised about this study, but of course it is good for them to correct mistakes and omissions when they find them.”
Watson writes in an email to The Scientist that the authors “have not addressed the other nine points referred to in the letter, and we do not understand why they cannot at least provide data aggregated by country rather than by continent.” He adds that the signatories on the letter would also like to know which countries in Africa the team is working worth.
“By allowing the authors to post this correction and not address any of the other concerns,” Watson continues, “The Lancet appear to [be] stating that so far they are not worried about the reliability of the study.”
Surgisphere is currently headquartered in Palatine, Illinois, and run by Desai, who trained in vascular surgery, a subject on which he has published many scientific articles and books. Until February 10 of this year, Desai was employed by Northwest Community Hospital (NCH) in suburban Arlington Heights. He tells The Scientist that he resigned for family reasons.
Court records in Cook County, Illinois, show that Desai is named in three medical malpractice lawsuits filed in the second half of 2019. He tells The Scientist in a statement sent through his public relations representative Michael Roth of Bliss Integrated that while he can’t comment on ongoing litigation, he “deems any lawsuit naming him to be unfounded.”
He also sent a comment purporting to be from Alan Loren, the executive vice president and chief medical officer of NCH: “Dr. Desai was employed at NCH and resigned in February 2020. We did not have any problems with him while he was here.”
Asked by The Scientist if he made this statement, Loren says, “What I can tell you is that he was employed here and he did resign. I can’t speak to whether or not there were any problems.” He adds that he spoke to Desai on May 28 and told him that “what I recall is that he resigned. I don’t remember the exact date. And that was it.”
Desai is now focused on Surgisphere, which currently has 11 employees, he tells The Scientist. Surgisphere’s website states that, “When Dr. Sapan Desai founded Surgisphere Corporation, the mission was simple: to harness the power of data analytics and improve the lives of as many people as possible.” Desai tells The Scientist that his company has always been involved in data analytics.
When Desai established the company in 2008 while a surgical resident at Duke University in Durham, North Carolina, Surgisphere Corporation’s most visible activity was marketing textbooks, produced by Surgisphere, to medical students.
Sapan Desai says he can understand people’s concerns and that the burden of proof rests with Surgisphere.
Reviews of the company’s products on Amazon are polarized, and a handful of positive reviews that appeared to impersonate actual physicians were removed when those doctors complained to Amazon. Kimberli S. Cox, a breast surgical oncologist based in Arizona, tells The Scientist that she was one of several practicing physicians who in 2008 discovered five-star reviews next to names that were identical or very similar to their own, that they had not written. She and her colleagues successfully persuaded Amazon to take the reviews down.
Desai denies that he knew about or was in any way involved in the posting of fake reviews for Surgisphere’s products. “If I wanted to review my own products, I could do it in my own name,” he says. Amazon did not return requests for comment before this story was published.
When Desai moved to the University of Texas Health Science Center at Houston in 2012 as a fellow in vascular surgery, he registered Surgisphere Corporation in Texas. By that point, Surgisphere had started publishing the Journal of Surgical Radiology, a medical journal that, according to its website, “accrued over 50,000 subscribers spanning almost every country around the world” from 2010 to 2013.
The website further notes that, “With almost one million page views per month, J Surg Rad earned a reputation as one of the first high quality peer-reviewed online medical journals. The Journal was indexed by most of the major medical indexes, and specific articles still appear in PubMed, EBSCO, and other sources.”
“It was amazing how fast we were able to grow it,” Desai tells The Scientist. “We had quite the editorial board.” The last issue was published in January 2013. “Running a medical journal is a full-time job,” he says. “I ran out of time.”
The profile of Surgisphere has risen dramatically during the COVID-19 pandemic. In addition to the recent Lancet study, Surgisphere provided data for a study published in the New England Journal of Medicine earlier this month. That study, which stated it was based on data from 169 hospitals in Asia, Europe, and North America, reported that cardiovascular disease was associated with increased risk of death among hospitalized COVID-19 patients.
However, heart drugs known as ACE inhibitors and ARBs, which some other studies had hinted were associated with an increased risk of death in people hospitalized with COVID-19, were not associated with higher mortality in these patients, the study concluded.
Currently, Surgisphere is providing data for another COVID-19 study with Lee Wallis, the head of emergency medicine for the Western Cape Government, the University of Cape Town, and Stellenbosch University. Like the study coauthors on the Lancet paper, Wallis and his collaborators helped design the study, but all of the raw data are kept by Surgisphere as proprietary information.
Wallis tells The Scientist that he has seen aggregated rather than hospital-level data, but that he is satisfied by Desai’s detailed descriptions of the dataset, and that all the necessary ethical and data-ownership requirements have been met.
The company has publicized other projects, too. In early March, a story appeared on a medical device information site touting a COVID-19 diagnostic tool developed by Surgisphere that could identify patients “likely to have coronavirus infection” with “93.7% sensitivity and 99.9% specificity.” The story, which Desai says Surgisphere did not write, quotes Desai as saying: “This tool is the first effective weapon in the fight against this global pandemic.”
Desai says that the story he’s quoted in “appears to misconstrue the resources we created,” directing The Scientist to descriptions of a “COVID Severity Scoring Tool” and a “COVID-19 Triage Decision Support Tool” on the company’s website. The Scientist could not obtain more information about exactly how the tools worked or how estimates of their specificity and sensitivity were calculated.
As for The Lancet hydroxychloroquine study, Desai says he can understand people’s concerns and that the burden of proof rests with Surgisphere. “We want to prove this to the world,” he tells The Scientist. “One thing that we might be able to do is get what we’ve done audited. That will be external, third party, independent of who we are, and can help validate all of this.”
Its about time
Sounds like he wants to investigate himself

I have been following this - it is amazing and all Freepers should pay attention. This is like CNN in an elevator - it is wrong on so many levels. I highly recommend checking out James Todaro’s feed

We have a very dodgy company, unknown actors supporting them, a press that made no effort to investigate, a journal that published shoddy work, and a NGO that took this at face value.
All the institutions are broken. This is why we had the revolution of 2016. The Trump phenomena, IMHO, can be explained in 3 words:
The “experts” aren’t.
Thanks again S&F for keeping up on this.
No, I just read the headlines. Did I miss anything?
There are millions of Hydroxychloroquine success stories that aren't swirled on social media... you can't read those, they give other views....
He’s a PT Barnum / Obama style crook. Plain and simple.
Another article yesterday pointed out the suspiciously low variance in the data for the 96,000 people.
AND, last but not least, we have a President who just severed relations with that crooked and complicit NGO. HURRAH President Trump!
Still say “Its over. We have lost this battle. We need to move on.”?

no no no- can’t be- NY’s ‘study’ claims there is ‘no benefit’ and ‘dangerous’ for HCQ too- so it must be true- (Don’t listen to the reams and reams of evidence coming in from all over the world that HCQ is saving 10’s of 1000’s of lives- we must only listen to the anti-Trump TDS NY and Lancet ‘studies’ (which were nothing but observations really- not even real studies) - we must only listen to ‘studies’ that ‘studied’ the effect of HCQ alone on patients who were too sick for anything to work- we must listen only to those who claim it ‘could be dangerous in given circumstances’, and we must cower in fear over a drug that is far safer than aspirin is-
Yes. It’s worth reading. This is a serious story of a crooked company publishing crooked / cooked results that got published in Lancet and used by WHO to justify suspending enrollment in hydroxychloroquine trials in a study of four treatment options for COVID-19.
This isn’t quite in Obamagate territory, but it’s very serious corruption of the global health system by a shady individual. Why did he do this? I’d wager TDS is at the bottom of it.
It should be a HUGE story.
Dr Tedros, the dirty head of WHO, hired this dirty “expert” to get back at Trump after Trump cut off WHO from American funds and criticized Tedros. Kind of like hiring an “expert” to submit expert testimony on your side during litigation. You pay them to testify to a foregone conclusion for your side not for impartial research. Usually the “experts” on either side of the case cancel each other out.
QuartzClinical operates in Analytics, Big Data, Business Intelligence, Data Integration, Health Care, Information Technology, Machine Learning, Medical, Predictive Analytics, Software. Yet there is NOBODY in the company with those skill sets.
CrunchBase says Surgisphere has one employee, CEO Sapan Desai, MD, PhD, MBA, FACS.
LinkedIn shows Ariane Anderson is the "Director Of Sales Marketing" at Quartz Clinical from Sep 2018 to Present. She has an Associate's [sic] Degree in General Education from Chaffey College; completed the Phlebotomy certified program at the Phlebotomy Learning Center; and earned a Certificate as a Medical/Clinical Assistant from Chaffey College.
I'd say that Sergio Ritter is doing an exemplary job in the "Creative" department. I'd wager he is a protege of Don Draper.
I had not thought of that, but I'll bet you are 100% correct.
To me it sounds much more like Hillary Clinton getting the DNC and her campaign to use the Perkins Coie law firm to pay for the fantasy "Steele Dossier."
Brigham & Women’s Hospital DR’S WORKED WITH THE CIA..
How doctors helped the CIA get better at torture
Dan Diamond December 10, 2014
Its not uncommon around the world to see doctors involved in torture. Reviewing the Senate Intelligence Committees newly released report, Atul Gawande, Samuel O. Thier Professor of Surgery at Brigham and Women’s Hospital, points to nearly a dozen individual examples of physicians playing a role in the CIAs interrogation and treatment of detainees.
From the article: “hydroxychloroquinea drug that, while unproven as a treatment for COVID-19, has been in use in hospital settings for decades and had not shown such major negative effects in studies up until this point.”
Horseapples. Are we to believe that all those patients who’ve received hydroxychloroquine for lupus, arthritis, and malaria were treated only in hospitals?
When I was in the Army in Korea (74/75), hydroxychloroquine was on everytable in the mess hall. We were ordered to take IIRC two tables a week. No one was in a hospital environment. No one was under a doctor’s care. No one suffered adverse reactions. The drug is incredibly safe. About as unsafe as aspirin.
