A council review recommends a pilot scheme to extend opening hours, amid continuing calls to restore the town’s full A&E department, which closed in 2005.
The centre currently opens from 8am to 8pm, seven days a week, seeing approximately 100 patients daily, according to the report.
Councillors agreed to send the review forward for responses from health partners, with those responses due to be considered by cabinet in November.
But Cllr Julia Wassell said Wycombe needed a “far more developed treatment centre”, describing how she had taken people to urgent care before having to take them onwards to Stoke Mandeville Hospital.
Speaking at Buckinghamshire Council’s health and adult social care select committee, she linked the review to calls for A&E’s return.
She said: “There is a very strong feeling in Wycombe that people are severely disadvantaged.
“And I’m pleased to see that this report provides some evidence for that.”
The report recommends that FedBucks, supported by the relevant commissioner, pilot extending opening hours until 10pm to help manage demand across the healthcare system.
An evaluation would examine how many patients used the additional hours and the seriousness of their conditions.
Cllr Wassell questioned whether the extension would meet the wider need, saying she would be inclined to abstain if members voted on that recommendation separately.
“I do feel that Wycombe needs a far more developed treatment centre,” she said.
The centre treats urgent conditions that are not life-threatening, including minor injuries and illnesses. The report says most patients are treated there without needing onward referral to hospital.
The review also calls for equitable funding for GP surgeries in Buckinghamshire’s most deprived areas to improve access.
Cllr Wassell asked whether there should be a timetable for addressing that inequality.
Committee chair Cllr Shade Adoh said the recommendation already called for action “as a matter of urgency”.
She said councillors would have further opportunities to review progress and hold partners to account.
Cllr Alan Sherwell supported the report, arguing that patients unable to secure GP appointments were turning to A&E, adding pressure to emergency services.
Principal scrutiny officer Elizabeth Wheaton said health partners could agree with recommendations, accept them in part or disagree.
Accepted recommendations would return to the committee for monitoring.
The later closing time remains a recommendation for a pilot. The proposal comes amid continuing calls to restore Wycombe Hospital’s full A&E department, with a petition demanding it return having reached 11,300 signatures.
