摘要
Background With diminishing reimbursement rates and strained public payer budgets, a high-volume inpatient procedure, such as total knee arthroplasty (TKA), is a common target for improving cost efficiencies. Methods This prospective case-control study compared the cost-minimization of same day discharge (SDD) versus inpatient TKA. We examined if and where cost savings can be realized and the magnitude of savings that can be achieved without compromising quality of care. Outcome variables, including detailed case costs, return to hospital rates and complications, were documented and compared between the first 20 SDD cases and 20 matched inpatient controls. Results In every case-control match, the SDD TKA was less costly than the inpatient procedure and yielded a median cost savings of approximately 30%. The savings came primarily from costs associated with the inpatient encounter, such as surgical ward, pharmacy and patient meal costs. At 1 year, there were no major complications and no return to hospital or readmission encounters for either group. Conclusion Our results are consistent with previously published data on the cost savings associated with short stay or outpatient TKA. We have gone further by documenting where those savings were in a matched cohort design. Furthermore, we determined where cost savings could be realized during the patient encounter and to what degree. In carefully selected patients, outpatient TKA is a feasible alternative to traditional inpatient TKA and is significantly less costly. Furthermore, it was deemed to be safe in the perioperative period. Contexte Dans le contexte de budgets publics serres et de taux de remboursement a la baisse, une intervention chirurgicale en service interne a volume eleve, comme l'arthroplastie totale du genou, est souvent ciblee pour ameliorer le rapport cout-efficacite. Methodes Cette etude cas-temoins prospective a fait une analyse de minimisation des couts de l'arthroplastie totale du genou en chirurgie d'un jour et en service interne. Nous avons examine si et oU des economies peuvent etre realisees et l'ampleur des economies pouvant etre obtenues sans compromettre la qualite des soins. Les variables dependantes, notamment les couts detailles des cas, le taux de retour a l'hopital et les complications, ont ete documentees, puis comparees entre les 20 premiers cas de chirurgie d'un jour et 20 cas-temoins apparies de chirurgie en service interne. Resultats Pour chaque appariement cas-temoins, l'arthroplastie totale du genou en chirurgie d'un jour etait moins couteuse que la chirurgie en service interne et a genere des economies medianes d'environ 30 %. Les economies decoulaient principalement des couts associes a l'hospitalisation du patient tels que les couts de l'unite de soins chirurgicaux, de la pharmacie et des repas du patient. Apres 1 an, ni l'un ni l'autre des 2 groupes ne presentait de complications majeures, de retours a l'hopital ou de readmissions. Conclusion Nos resultats concordent avec les donnees anterieures publiees sur les economies associees a l'arthroplastie totale du genou pratiquee en chirurgie d'un jour ou en service interne de courte duree. Nous sommes alles plus loin en documentant egalement oU les economies se situaient dans un modele cas-temoins. De plus, nous avons determine les aspects de la rencontre avec le patient oU des economies pourraient etre realisees et l'ampleur de ces economies. Chez des patients soigneusement choisis, l'arthroplastie totale du genou en chirurgie d'un jour est une solution de rechange envisageable a l'arthroplastie totale du genou traditionnelle en service interne et est beaucoup moins couteuse. De plus, elle a ete jugee securitaire en periode perioperatoire.
