Background: To audit the safety of the early hospital discharge care model offered by a Hospital-at-home (HAH) unit during early postoperative follow-up of these patients, and to determine whether this care model is more efficient compared to the traditional care model. Methods: A prospective study of 50 patients included consecutively for 1 year in an early discharge programme after laparoscopic colorectal surgery was performed. As of day 3 after surgery, if the patient met the relevant inclusion criteria they were transferred to the HAH unit. The domiciliary protocol consists of daily clinical follow-up and a series of analytical controls with the purpose of early detection of postoperative complications. If the clinical course was favourable on day 7 after the postoperative period the patient was discharged. Results: A total of 66% were males, and the mean age was 60.6 years. The surgical procedure most commonly performed was sigmoidectomy. The mean stay was 5.5 days. There were no deaths during follow-up. The average estimated cost per day of stay in a HAH system was EUR 174.29 whilst the same average cost on a surgery ward stood at EUR 1,032.42. Conclusions: For patients undergoing major colorectal surgery with minimally invasive surgical technique, an early hospital discharge care programme by means of referral to a HAH unit is a safe and efficient care model which entails a significant cost saving for the public healthcare system.
