Abstract
BACKGROUND

While Singapore attains good health outcomes, Singapore’s healthcare system is confronted with bed shortages and prolonged stays for elderly people recovering from surgery in acute hospitals. An Acute Hospital-Community Hospital (AH-CH) care bundle has been developed to assist patients in postoperative rehabilitation. The core concept is to transfer patients out of AHs when clinically recommended and into CHs, where they can receive more beneficial dedicated care to aid in their recovery, while freeing up bed capacities in AHs.

AIM

To analyze the AH length of stay (LOS), costs, and savings associated with the AH-CH care bundle intervention initiated and implemented in elderly patients aged 75 years and above undergoing elective orthopedic surgery.

METHODS

A total of 862 1:1 propensity score-matched patients aged 75 years and above who underwent elective orthopedic surgery in Singapore General Hospital (SGH) before (2017-2018) and after (2019-2021) the care bundle intervention period was analyzed. Outcome measures were AH LOS, CH LOS, hospitalization metrics, postoperative 30-d mortality, and modified Barthel Index (MBI) scores. The costs of AH inpatient hospital stay in the matched cohorts were compared using cost data in Singapore dollars.

RESULTS

Of the 862 matched elderly patients undergoing elective orthopedic surgery before and after the care bundle intervention, the age distribution, sex, American Society of Anesthesiologists classification, Charlson Comorbidity Index, and surgical approach were comparable between both groups. Patients transferred to CHs after the surgery had a shorter median AH LOS (7 d vs 9 d, P < 0.001). The mean total AH inpatient cost per patient was 14.9% less for the elderly group transferred to CHs (S$24497.3 vs S$28772.8, P < 0.001). The overall AH U-turn rates for elderly patients within the care bundle were low, with a 0% mortality rate following orthopedic surgery. When elderly patients were discharged from CHs, their MBI scores increased significantly (50.9 vs 71.9, P < 0.001).

CONCLUSION

The AH-CH care bundle initiated and implemented in the Department of Orthopedic Surgery appears to be effective and cost-saving for SGH. Our results indicate that transitioning care between acute and community hospitals using this care bundle effectively reduces AH LOS in elderly patients receiving orthopedic surgery. Collaboration between acute and community care providers can assist in closing the care delivery gap and enhancing service quality.

Core Tip: This study evaluated the cost-effectiveness of an intervention that bundled Acute Hospital-Community Hospital (AH-CH) care. The AH-CH care bundle intervention effectively reduced AH length of stay (LOS) and costs for elderly patients aged 75 and above undergoing elective orthopedic surgery in Singapore General Hospital. Our findings indicate that systematically transitioning care between AH and CH using this care bundle reduces AH LOS and achieves cost savings. This intervention increases public hospital bed capacity and reduces inpatient hospitalization costs.
