The Care Quality Commission (CQC) Adult inpatient survey is the major survey of inpatient experience of hospital services in England.
Data was collected between August 2017 and January 2018 from patients who stayed in hospital during July 2017. The 2017 inpatient survey involved 148 NHS acute and NHS foundation trusts in England.
Patients successfully completed 72,778 questionnaires – a response rate of 41%. Of these, 69,151 responses had a known ethnicity. The sample sizes for patients with a known ethnicity achieved was lower in 2013/14 (58,624 responses) and 2014/15 (55,292 responses) but higher in 2015/16 (76,993 responses) and 2016/17 (73,358).
It is important to be able to compare NHS trusts which treat patients with different characteristics. In addressing any potential bias, CQC standardise different organisations to a common average mix of patients. This removes differences due to gender or age which makes the comparison easier.
Trusts were asked to include as their sample the final 1,250 patients to be discharged by 31 July (a small number of specialist trusts could not reach the required sample size). This is slightly different to previous years when trusts could choose whether to select patients discharged in either June, July or August. This is not thought to have disrupted the time series since discharges still occurred at roughly the same time of year and therefore patient experience is not expected to be very different.
Certain groups of patients were excluded from the survey before trusts drew their samples, including:
- patients who had died
- children or young people under 16 years old during July 2017
- women using obstetrics or maternity services, including those who had a spontaneous miscarriage
- patients admitted for planned termination of pregnancy
- psychiatry patients (patients who received treatment for a mental health condition)
- day case patients (patients who arrived at and left hospital on the same day)
- private patients (non-NHS)
- NHS patients treated at private hospitals
- any patients who were known to be inpatients at the time samples were drawn
- patients without a UK postal address
- patients who opted out of having their details used for anything except clinical care
