Winkenwerder was one of the officials who pursued a military anthrax vaccine immunization program and its potential expansion to include civilians.[8][9] While in office, Winkenwerder also documented the U.S. military smallpox vaccination program through a study.[10] Winkenwerder also organized a task force that worked on a plan to provide benefits for reserve and National Guard forces, which opened Tricare to non-mobilized reserve servicemen without employment or health insurance.[11]
In 2005, Winkenwerder testified before Congress on the subject of military mental health.[12]
Also in 2005, during his tenure at the Department of Defense, Winkenwerder issued an internal policy statement reiterating the importance of 'humane treatment of detainees' during interrogations at the Guantanamo Bay detention camp.[13] The guidance specified that military medics charged with the medical care of detainees must be guided by medical ethics, make medically appropriate decisions and report inhumane treatment.[14] It was later reported that military intelligence, which did not report to Winkenwerder, allowed some 'non treating' medical and science personnel to assist in the interrogations.[13] Winkenwerder said that had resulted in a very small number of reports of patient abuse by military medics.[14]
Winkenwerder launched AHLTA (Armed-forces Health Longitudinal Technology Application), which was the world’s largest electronic health record system at the time of its implementation, in order to transition the armed forces to using electronic health records.[18]
He stepped down from his post in April 2007, following criticism of the Department of Defense's medical records system he had overseen.[6]
In 2004, Winkenwerder received the Alumni Achievement Award from his alma mater, the Wharton School of Business, for his work with the Department of Defense.[20] In 2005, he went on to receive the Dr. Nathan Davis Award from the American Medical Association.[4]
In 2007, Winkenwerder was hired as a senior adviser by Deloitte.[21] From 2007 to 2012, Winkenwerder has served as chairman of The Winkenwerder Company.[1] In 2009, Johns Hopkins Medicine retained The Winkenwerder Company to help develop advanced health care services for government agencies.[22]
From 2012 to 2014, he served as CEO of Highmark.[1][23] During his tenure, Highmark established the Allegheny Health Network after acquiring several hospitals in Western Pennsylvania, including Saint Vincent Hospital.[24][25][26] In May 2014, Winkenwerder was removed from the position.[23][27]
In late 2014, Winkenwerder established the private equity firm Winkenwerder Strategies.[28]
He also sits on the board of directors of The Bob Woodruff Foundation.[29] He is also a board member at Confluent Health,[30] Accreon,[31] and Cureatr, where he served as vice chairman of the board.[32] Since 2015, Winkenwerder has served as the board director of CitiusTech Inc, becoming its Chairman in 2017.[33] He acted as an advisor to candidates in the US national elections of 2008 and 2012.[34]
