Study ID | Country | Comorbidity | Study type | Number of participants | Aspect of quality of care | Evidence that care is different? | Reported differences in care/treatment |
---|---|---|---|---|---|---|---|
Connolly [92] | UK | DM, Stroke | Cross sectional | 700 PWD (compared to people without dementia on QOF register) | Monitoring and treatment | Yes | PWD -significantly lower on 73% of QOF indicators; including peripheral pulses check, neuropathy testing, cholesterol measures for stroke. |
