Bariatric surgery is the most effective treatment for severe obesity and its associated diseases. Advances in surgical techniques, enhanced recovery protocols, and multimodal perioperative care have made earlier hospital discharge possible while maintaining patient safety.
This observational cohort study aims to evaluate the economic impact of an early discharge pathway consisting of 24 hours of hospital stay followed by Hospital-at-Home care, compared with the conventional 48-hour hospital stay after bariatric surgery.
The study will compare healthcare costs, resource utilization, clinical safety, organizational efficiency, applicability of the early discharge pathway, and patient satisfaction between both postoperative care models under routine clinical practice.
The implementation of Enhanced Recovery After Surgery (ERAS) protocols, minimally invasive surgical techniques, and optimized multimodal perioperative management has significantly improved postoperative recovery after bariatric surgery, allowing earlier hospital discharge without compromising patient safety.
At Hospital Universitari Parc Taulí, an early discharge pathway combining 24 hours of postoperative hospital stay with structured Hospital-at-Home (HaH) care during the second postoperative day was implemented as part of routine clinical practice in February 2025. This model was developed to optimize healthcare resource utilization while maintaining the same overall duration of postoperative medical supervision as the conventional pathway.
This study is an ambispective comparative observational cohort study designed to evaluate the economic impact of this postoperative care pathway under real-world clinical conditions. Patients managed with the conventional 48-hour hospital stay before implementation of the protocol will be compared with patients managed using the early discharge plus Hospital-at-Home pathway after implementation.
The study will evaluate direct healthcare costs, healthcare resource utilization, clinical safety, organizational efficiency, applicability of the early discharge pathway, and patient satisfaction. The results are expected to provide evidence regarding the economic and organizational impact of Hospital-at-Home as an alternative postoperative care model following bariatric surgery within a public healthcare system.

The study population consists of adult patients with severe obesity undergoing elective bariatric surgery at Hospital Universitari Parc Taulí. The study includes two consecutive cohorts: patients treated before implementation of the early discharge pathway with conventional postoperative hospitalization, and patients treated after implementation of the early discharge pathway with Hospital-at-Home care as part of routine clinical practice.

Exclusion Criteria:
Patients who underwent elective bariatric surgery before implementation of the early discharge pathway and received conventional postoperative care with approximately 48 hours of inpatient hospital stay.
Patients who underwent elective bariatric surgery after implementation of the early discharge pathway and received 24 hours of inpatient hospital stay followed by structured Hospital-at-Home care during the second postoperative day.
Mean Direct Healthcare Cost per Patient
Mean direct healthcare cost per patient, including hospital stay, Hospital-at-Home care, emergency department visits, hospital readmissions, and additional healthcare resources used during the postoperative follow-up period.
Time frame: Within 90 days after bariatric surgery
Length of Hospital Stay
Length of conventional inpatient hospital stay following bariatric surgery, measured in days.
Time frame: From surgery until hospital discharge (approximately 24-48 hours).
Hospital-at-Home Utilization
Utilization of the Hospital-at-Home program, assessed by the number of home care days and home visits provided after hospital discharge.
Time frame: During the Hospital-at-Home follow-up period (postoperative day 2).
Emergency Department Visits
Number of postoperative emergency department visits occurring during the follow-up period, regardless of the reason for consultation.
Time frame: Within 90 days after bariatric surgery.
Hospital Readmissions
Number of hospital readmissions occurring during the postoperative follow-up period.
Time frame: Within 90 days after bariatric surgery.
Postoperative Complications
Incidence and severity of postoperative complications, including complications classified according to the Clavien-Dindo classification, reinterventions, and postoperative mortality.
Time frame: Within 90 days after bariatric surgery.
Hospital Bed-Days Saved
Number of conventional hospital bed-days saved by implementing the early discharge pathway with Hospital-at-Home compared with the conventional postoperative care pathway.
Time frame: Perioperative (from surgery until hospital discharge, up to 48 hours)
Applicability of the Early Discharge Pathway
Proportion of patients eligible for and successfully managed with the early discharge pathway including Hospital-at-Home care, as well as the reasons for non-inclusion when applicable.
Time frame: Perioperative (from surgery until discharge allocation, up to 48 hours)
Patient Satisfaction
Patient satisfaction assessed using a structured questionnaire evaluating the information received, hospital stay, Hospital-at-Home care, anxiety related to home recovery, overall satisfaction, willingness to repeat the care pathway, and willingness to recommend it to other patients.
Time frame: At completion of postoperative follow-up (within 90 days after bariatric surgery).
