Enhanced Recovery After Surgery (ERAS) is a multimodal perioperative care pathway designed to achieve early recovery for patients undergoing major surgery. ERAS allows for the incorporation of evidence based practices and incorporated a comprehensive assessment of the patient's journey through the surgical process from pre-operative screening through to post-operative care. The purpose of this study was to determine if optimisation of ERAS protocol with pre-operative screening and incorporating patient-specific factors into their post operative care would improve length of stay (LOS) and readmission rates following total joint arthroplasty (TJA) in a Canadian community hospital setting.

The study collected clinical, demographic data and the physical status perioperative using the American Society of Anaesthesiologists (ASA) classification on 508 patients who underwent TJA between January and August 2015 and compared similar data from the same time frame in the previous calendar year prior to implementation of the pathway. Cohorts were analysed for length of stay (LOS), readmission rates, Pre-operative assessments (completed by anaesthesia, nursing and pharmacy), relevant labs, patient history (surgery, medical, social), and patient values were all considered when developing a specific patient plan for care post-operatively. A post-operative management tool was used to optimise pain control, post-operative nausea and vomiting, bowel management, diabetes blood glucose control, venous thromboembolism prophylaxis, as well as monitoring parameters specific to patient medical history (e.g. respiratory, cardiac). While in hospital, physiotherapy and nursing were consulted by the pharmacist to assess whether patient's post op management needed to be altered to optimise mobilisation and recovery in hospital. The average patient's LOS and readmission rates in 30 days was analysed to assess the change after implementation of the post-operative management tool based on patient specific factors.

A total of 508 patients (mean age: 66 years), ASA classification was 3 or greater for 430 patients. The patients were assessed for LOS, readmission rates in 30 days. The mean LOS decreased from 3.6 to 3.3 days after optimisation of the ERAS protocol (student t test p=0.021). The 30-day readmission rate decreased from 2.9% to 1.4% post intervention (z test p=0.087) when compared to the same time period in the previous calendar year prior to protocol implementation. Overall, the cost savings to optimising the ERAS protocol for the hospital is substantial; with approximately $238 saved per patient.

Pre-operative screening and incorporating patient-specific factors into an individualised care plan to optimise the ERAS protocol for TJA reduced mean length of stay without a concomitant increase in readmission rates with significant cost saving.
