A dialysis center in Waterbury has been fined $5,000 by the state for numerous violations, including having a leaky roof and ceilings, clogged gutters, rusted chairs, expired nutritional supplements, a stained dialysis machine and a treatment unit that was only 60 degrees. Inspectors from the state Department of Public Health found the problems between May and September 2015 at the Waterbury Dialysis Center on Highland Avenue in Waterbury. In a consent order signed March 9 with DPH, the center, part of the DaVita Dialysis chain based in Denver, agreed to hire an environmental consulting firm to keep the state advised that the violations are being corrected. It also agreed to have a corporate regional nurse from DVA Healthcare Renal Care of Denver make weekly visits to verify and report to the state that staffing was adequate and that infection control principles were being followed. Inspectors found some lapses in patient care.
