More than 95% of patients with a disability were satisfied with their care at Northumbria Healthcare, new figures show.
But Disability Rights UK said the low satisfaction figures across England should give NHS providers a "wake-up call to do better" when it comes to caring for patients with a disability.
The patient-led assessment of the care environment is an annual survey of NHS patients, who review the care they received across a variety of topics, including privacy, food, and cleanliness.
It shows 97.7% of patients with a disability who received care at Northumbria Healthcare NHS Foundation Trust last year were happy with their treatment – well above the average of all providers across the country at 82.5%.
But Fazilet Hadi, head of policy at Disability Rights UK, said the low satisfaction rates nationally "should give NHS and independent care providers a wake-up call to do better".
"It is not good enough that one in five people with dementia or a disability are not satisfied with the care they receive," Ms Hadi added.
Meanwhile, the figures show 80.6% of dementia patients across the country were satisfied with the level of care they received – this rose to 97.1% at Northumbria Healthcare.
The survey also showed Northumbria Healthcare NHS Foundation Trust scored 99.6% in its levels of cleanliness, 95.6% in the food and drink served, and 96.2% in the dignity and wellbeing of the patients.
The trust also scored 98.1% in condition, appearance, and maintenance.
A Department of Health and Social Care said it is supporting social care with up to £7.5 billion over the next two years.
