A doctors' surgery in Lincolnshire has been placed in special measures after a health watchdog found its patients were at risk of harm.
Westside Surgery in Boston was rated "inadequate" by the Care Quality Commission (CQC), which found it was neither a safe nor effective service.
Staff at the surgery failed to review patients' medicines and did not keep track of uncollected prescriptions.
Lincolnshire East CCG said it was "disappointed" by the rating.
At the inspection in November, the CQC found patients were being prescribed high-risk medicines which were not checked for interactions against any other medicines currently being prescribed.
Inspectors found no realistic plans were in place to achieve quality care, despite a willingness from senior practice partners to make changes where necessary.
'Highest quality care'
In addition, blank prescription forms and pads were stored away but their use was not monitored, gaps were found in mandatory training for staff, and there was no system was in place to routinely contact bereaved families.
The CCG's chief nurse Tracy Pilcher said: "In this case, the failures relate to certain areas where the CQC considers the practice to be inadequate or requiring improvement.
"These areas have either been resolved or are being addressed by the practice with the full support of [the CCG].
"The CQC has rated Westside Surgery as good in relation to providing caring services and we are confident that the practice will build on this to ensure it makes the required improvements in other areas.
"We would like to assure patients of our commitment to commissioning the highest quality, safe care for everyone."
The CQC rated the surgery as "inadequate" overall, and in matters of safe services, effective services, and leadership. It received a "good" rating for its caring services, and "requires improvement" in whether services were responsive to people's needs.
It will be re-inspected within the next six months.
