Patient Reported Outcome Measures
(PROMs)

Patient Reported Outcome Measures (PROMs) assess the quality of care delivered to NHS patients from the patient perspective. Currently covering two clinical procedures, PROMs calculate the health gains after surgical treatment using pre- and post-operative questionnaires.

PROMs is a national initiative devised to assess the quality of care delivered to NHS patients. Patients undergoing elective inpatient surgery for hip and knee replacement, funded by the NHS are asked to complete questionnaires before and after their operations to assess improvement in health as perceived by the patients themselves. When you had your hip or knee replacement, you will have been asked to fill in a PROMs (Patient Reported Outcome Measures) questionnaire. Additionally, you will have been contacted approximately six months after your operation with an invitation to fill out another, follow-up questionnaire. The purpose of these questionnaires is to enable the NHS to measure and improve the quality of care for all patients undergoing hip or knee joint replacement surgery.

You can find information on this national initiative here.

From April 2020 to March 2021:

The National Joint Registry invites patients to complete an additional questionnaire, approximately one year after their joint replacement operation. We will also be asking you to complete two further questionnaires: one three years after your operation, and one five years after your operation. These questionnaires are identical to the one that you completed six months after your operation.

The questionnaires that you have already completed will provide an invaluable insight into patients’ pain, mobility and general health immediately following surgery, but it is recognised that a large-scale study is necessary to look at the long-term effects of hip and knee replacement surgery. It is widely known that the outcomes of these types of procedures evolve over time, and that some benefits and some risks will not become apparent in the first six months. The recognition of the need to undertake a longer term study has resulted in the NJR receiving permission to send out additional questionnaires.

By undertaking this study, we will be examining success from the point of view of the patient, specifically looking at the reduction in pain, improvement in mobility, and the impact on quality of life. This is different to many studies which look at, for example, the type of implant, how it was put in, and how long it lasted before it had to be replaced. These types of study are essential but do not include a patient’s view of the outcome. With your help the work will help us to achieve our aims of ensuring the best clinical care for patients and improving the success of hip and knee joint replacements by helping surgeons to identify best practice.

What will happen to your data?

In applying for permission to undertake the study, the relevant authorities ensured that all that patient confidentiality and protecting the data are given the highest priority by the NJR.

The company undertaking the study on NJR’s behalf is NEC who is used to handling patient data and stores all information in its NHS-approved data centre. Your personal data will not be made available to anyone outside of the study.

How will your data be used?

The data from the questionnaires that we are asking you to complete will be linked to the data that you have already provided in the other two questionnaires. This data will be then be linked to data held by the National Joint Registry and the Hospital data (HES). Once the data is linked, any information that could be used to identify you will be removed before any analysis takes place.

The data from the NJR will provide information about the type of surgery you had, how the operation was carried out, and what implants you received. The data from HES will provide us with more details about your operation, for example, how long you had to stay in hospital and details of any other operations or illnesses that you may have had following your operation.

The completed, combined dataset will not contain any details that could be used to identify individual patients and will be analysed to provide information to surgeons, hospitals and patients that will enable them to improve the success of hip and knee replacement surgery for all patients.
