NHS Essex has released a detailed set of frequently asked questions following the confirmation that Norton Place health centre will close in September.
The site currently serves around 37,000 patients with about 250 weekly appointments, but services are set to be reorganised across other locations.
Bosses say the changes are not due to funding cuts, but instead reflect a national shift in how money is distributed to GP practices rather than Primary Care Networks.
However, the update states that Shoebury remains a “priority” due to expected population growth and higher levels of deprivation.
Despite this, NHS Essex has highlighted ongoing difficulties in delivering long-promised plans for a new health facility in the area.
Bosses say rising construction costs, limited capital funding and wider financial pressures have prevented the project from moving forward.
They add that changes in government priorities and increasing demand on NHS resources have further complicated progress.
But, says it is continuing to work with Southend Council, GP practices and other partners to identify the “most sustainable long-term solution for primary and community healthcare” in Shoebury.
In the meantime, efforts are being made to improve existing facilities where possible, even though the current health centre building has recognised limitations.
Patients have been told to attend appointments as normal unless contacted, with assurances that services will continue, albeit potentially from different locations.
A spokesman for NHS Essex stated: “The current Primary Care Network review will continue separately from the longer-term work to improve healthcare facilities in Shoebury.
“Although securing funding for a new health facility remains challenging, we remain committed to working with partners to find sustainable solutions that meet the long-term healthcare needs of the Shoebury community.
“In the meantime, our priority is to ensure local people continue to have access to safe, high-quality NHS services.”
The closure of Norton Place, on Ness Road, has been branded a “terrible” blow for residents, who fear there will be no continuity of service.
