Using general practitioner records, hospital medical notes and through direct telephone conversation with patients, we investigated the accuracy of nine patient-reported complications after elective joint replacement surgery of the hip and knee. A total of 402 post-discharge complications were reported after 8546 elective operations that were undertaken within a three-year period. These were reported by 136 men and 240 women with an overall mean age of 71.8 years (34.3–93.2). A total of 319 (79.4%; 95% confidence interval, 75.4%–83.3%) reported complications were confirmed to be correct. Very high rates of correct reporting were demonstrated for infection (94.5%) and further surgery (100%), whereas the rates of reporting deep venous thrombosis (DVT), pulmonary embolism, myocardial infarct and stroke were lower (75%–84.2%). Dislocation, periprosthetic fractures and nerve palsy were associated with modest rates of correct reporting (36%–57.1%). More patients who had had knee surgery delivered incorrect reports of dislocation (p = 0.001) and DVT (p = 0.013). Despite these variations in accuracy, it appears that post-operative complications may form part of a larger patient-reported outcome programme for monitoring outcome after elective joint replacement surgery.
The outcomes programme of our institution has been developed from a system first used at Epsom and St Helier NHS Trust 15 years ago. The system was implemented at our institution when it opened in 2004, and has been used to collect data on over 17,000 joint replacement operations so far. A bespoke database is used to collect, analyse and report outcome data. An integrated system allows the collection of patient-reported outcome measures (PROMS), patient satisfaction scores, radiological assessment, and medical or surgical complications. Functionality allows the transfer of data from existing clinical management programmes, and the generation of customised letters and questionnaires to send to patients. Analysis of data and report production is fully automated. Data is collected pre-operatively, during the inpatient stay, and post-operatively at 6 weeks, 6, 12 and 24 months. Results are disseminated to the surgeons, the senior management team and the Clinical Governance Committee.Introduction
Methods
The need for the stringent surveillance of new devices was recognised by the NICE review of hip replacement surgery in 2000 and led to the Orthopaedic Data Evaluation Panel (ODEP) developing criteria for post-marketing surveillance (PMS) studies. This requirement has been reinforced by the recent recall of ASR devices. The South West London Elective Orthopaedic Centre's (EOC's) comprehensive outcomes programme has been adapted to manage and coordinate multi-centre, multi-surgeon, PMS studies. The system allows any schedule and combination of patient-reported outcome measures (PROMS), clinical and radiological assessments, and complications to be collected. Typically, PROMS are collected pre-operatively and yearly by post. Baseline clinical assessment is undertaken pre-operatively, with baseline radiological assessments pre- and post-operatively. Subsequent clinical and radiological assessments are usually obtained at the ODEP-mandated time points of 3, 5, 7 and 10 years post-operatively. Patients are telephoned twice yearly to document complications and any impending change of address.Introduction
