The trust provides more than 240 services across the county, working from community hospitals, specialist clinics and care homes.
The health care it provides ranges from childbirth to end-of-life care, as well as mental health services.
On Thursday, it had to temporarily remove six palliative care beds from use for end-of-life patients due to an “unexpected shortfall in consultant cover”.
The reform is part of the government’s 10-year health plan, designed to treat more people closer to home.
Advanced foundation trusts also have the opportunity to be designated as eligible to hold an integrated health organisation (IHO) contract to oversee the health budget for a defined local population.
The Northamptonshire trust is one of two undergoing an initial assessment for an IHO and is likely to find out whether it is successful later this year.
