Plain English summary of protocol
Background and study aims
Total knee replacement (TKR) involves replacing a damaged, worn or diseased knee with an artificial joint. It's a routine operation for knee pain most commonly caused by arthritis. In 2007-8 the NHS undertook over 70,000 TKRs in England and Wales, and the number of TKRs is expected to rise as the population gets older. We know that patients experience significant pain after a TKR operation and this can increase the time taken to get back to walking and normal activities. Pain levels may be changed if the painkillers are taken by the patient when they want to take them (patient-directed self-management of pain) rather than when the nurse gives them as part of a drugs round in hospital (treatment as usual). This study will compare these two methods.
Who can participate?
Adult patients (aged over 18) undergoing a primary (first) TKR operation.
What does the study involve?
Participants will be randomly divided into the two groups: patient-directed self-management of pain or treatment as usual. This study will investigate whether patient-directed self-management of pain improves levels of pain at three days after the operation or at discharge (whichever is the sooner) compared to treatment as usual. It will also compare the two groups up to 6 weeks after the operation for satisfaction with control of pain, return to walking and normal activities, any problems, and costs. We will also interview 10 patients and 10 ward staff to explore their experiences of the two methods.
What are the possible benefits and risks of participating?
It is hoped that the results of this study will help the NHS to improve pain control for patients after TKR. Information from this study may well be relevant to pain control after operations in general.
Where is the study run from?
Norfolk and Norwich University Hospital NHS Trust (UK).
When is study starting and how long is it expected to run for?
June 2011 to June 2013.
Who is funding the study?
National Institute of Health Research (NIHR) (UK).

Scientific title | A randomised controlled trial of patient-directed self-management of pain (PaDSMaP) compared to treatment as usual following total knee replacement. |
Study acronym | PaDSMaP |
Study objectives | To investigate if PaDSMaP reduces pain at 3 days post-operatively or discharge (whichever is sooner) after primary total knee replacement compared to treatment as usual |
Ethics approval(s) | Cambridgeshire 1 Research Ethics Committee, 30/12/2010, ref: 10/H0304/52 |
Health condition(s) or problem(s) studied | Musculoskeletal disease: Total knee replacement |
Intervention | Patients self-medicate their oral analgesics post total knee replacement when sufficently recovered from the anaesthetic. Treatment as usual comparator cohort have analgesics dispensed as per usual by nurses on drug rounds Follow up length: Six weeks; Study entry: Single randomisation only |
Intervention type | Procedure/Surgery |
Primary outcome measure | Pain levels for patients at three days post-operatively or at discharge (whichever is the sooner) as measure on a non-graded 10cm visual analogue scale (VAS) |
Secondary outcome measures | 1. Pain during inpatient stay and after six weeks post-operatively (non graded 10cm VAS) 2. Satisfaction with pain levels patient questionnaire 3. Satisfaction with Information About Medicines Scale (SIMS) 4. EuroQOL EQ-5D questionnaire (EQ-5D) 5. Oxford Knee Score (OKS) 6. Time to mobilisation after operation (e.g. day on which patient was able to stand up and transfer from bed to chair) 7. Medication usage (Inpatient Prescription Chart and CRF) 8. Adverse events (CRF) 9. A health resources questionnaire 10. Qualitative evaluation of patient's and health professionals' experiences |

Key inclusion criteria | 1. All adult patients (e.g. aged over 18) undergoing a primary total knee replacement operation 2. Must meet the Norfolk and Norwich University Hospital NHS Foundation Trust self-management of pain criteria 3. Are expected to require standard step 1-3 oral analgesics post-operatively (WHO 2009) 4.
