I have been involved in COVID-19 research with two research groups in Oxford ((OHDSI/NDORMS) and (Oxford University Global Surgery Group (OUGSG)/GTC/NDORMS) with whom I have an honorary academic fellow contract, and with other research groups in Palestine (OxPal Medlink) and at Harvard.

Some examples of my work:

With the OHDSI:
-Safety of hydroxychloroquine, alone and in combination with azithromycin, in light of rapid wide-spread use for COVID-19: a multinational, network cohort and self-controlled case series study.
An international characterisation of patients hospitalised with COVID-19 and a comparison with those previously hospitalised with influenza

With the OUGSG:
-Infection and mortality of healthcare workers worldwide from COVID-19: a scoping review

OxPal Medlink/Palestine:
-Healthcare workers preparedness for COVID-19 pandemic in the occupied Palestinian territory: a cross-sectional survey 

Gastrointestinal Complications in Critically Ill Patients with COVID-19

In a study recently published in the Lancet we have looked at the complications following surgery for patients with a peri-operative COVID-19 diagnosis. We have found that the mortality rate was 24% and the risk of pulmonary complication was 51%. This is the largest multi-centre study to-date to evaluate these complications in COVID-19 patients undergoing surgery. My involvement was in the writing and in the dissemination committees of COVIDSurg Collaborative which is leading the project.
