Carroll, 63, of Aurora, the former Vice President of Facilities and Institutional Services at MetroHealth, pleaded guilty in September 2009 to six charges, including conspiracy to commit bribery, obstruction of justice and filing false tax returns.
Carroll admitted to bribes valued at approximately $678,000 and came in the form of travel, gift cards, home improvements and home furnishings, according to court documents.
In exchange, Carroll and Greco exercised their discretion at East West's advantage on MetroHealth contracts.
Carroll, Greco and Patel funded the bribes by causing MetroHealth to pay inflated costs to East West, according to court documents.
Patel pleaded guilty in 2009. Greco was found guilty following a jury trial last year.
Carroll was also ordered by U.S. District Judge Kate O'Malley to pay $728,000 in restitution and perform 100 hours of community service upon his release from prison.
