Minimally Invasive Outpatient Total Hip Arthroplasty

Impact of process reengineering on technical efficiency of the health care provider

“…This means that the total volume of labour input would be reduced by 67.88% and the total volume of capital input would be reduced by 36.26%. This is in accordance with several cost studies which estimated an average cost savings of 17.6% to 57.6% for day hospital procedures relative to similar procedures performed in hospital (34)(35)(36)(37). All these results suggest that in the case of business process reengineering technical efficiency of a hospital increases.…”

Definitional Differences of ‘Outpatient’ Versus ‘Inpatient’ THA and TKA Can Affect Study Outcomes

“…The recent changes in healthcare insurance and the aging US population make the appropriate exploration of outpatient procedures in terms of safety and cost-effectiveness more important than ever. The large number of recent orthopaedic studies comparing inpatient and outpatient procedures underscores this importance [2,5,9,10,15,16,24,25,29,30,37,40,48].…”

“…The benefits of outpatient arthroplasty are reported to include higher patient satisfaction and reduced costs [15,29]. Multiple studies comparing the outcomes of inpatient with outpatient arthroplasty have been reported [2,5,9,10,15,16,24,25,29,30,37,40,48]. However, the difference between ''inpatient'' and ''outpatient'' is not as intuitive as one might think.…”

“…This ''observation'' status obscures the division between what is considered inpatient or outpatient. Some studies on outpatient arthroplasty have defined ''outpatient'' status as patients who were discharged the same day [5,9,10], patients who stayed at most one night at the hospital [2,4,24], patients who stayed at most two nights at the hospital [15,25], or simply provided stated status with no quantitative description [16,29,40].…”

Is Minimally Invasive Total Knee Arthroplasty Associated with Lower Costs Than Traditional TKA?

“…Total patient charges were defined as all in-hospital charges, minus the cost of prosthetic implants, associated with the patient's hospitalization, and these charges were provided to us by the hospital finance department. Direct cost in this analysis was defined as the cost of all professional services, personnel, facilities, and supplies required to perform the surgical procedure [3]. The hospital finance department necessarily uses slightly different methodologies for calculating direct cost in the different cost centers (departments and service areas such as laboratory, pharmacy, or therapy) in the hospital.…”
