仙骨膣固定術における仙骨子宮全摘出術対全子宮摘出術の費用分析

A cost analysis model of supracervical (SCH) versus total hysterectomy (TH) at the time of minimally invasive sacrocolpopexy (SCP) has not been established.

Minimally invasive sacrocolpopexy (SCP), a mesh-augmented pelvic organ prolapse (POP) repair, is frequently performed with concomitant hysterectomy, either a supracervical hysterectomy (SCH) or total hysterectomy (TH), with comparable POP outcomes with either approach. However, for SCH versus TH, there are important implications on cervical cancer screening and reported complication rates. Clinical outcomes data have not identified a clear preferred hysterectomy type at the time of SCP. This study aimed to perform a cost analysis to compare SCH versus TH at the time of SCP for POP.

A health care sector-perspective analysis was performed using a 10-year time horizon. Our model assumes that there is similar efficacy and patient satisfaction for SCH and TH, and that the age of patients undergoing SCP is 55 years (median age in the literature). The average cost of procedures and complications were estimated from publicly available data sources. Base-case probabilities for various complications were estimated through a PubMed literature search.

TH-SCP is $654 less costly per treatment case compared with SCH-SCP ($26,101 vs. $26,754). Three model variables have the potential to reverse this cost advantage when varied across their ranges: SCH-SCP surgery, TH-SCP surgery, and the cost of cervical screening. Based on our model assumptions, SCH-SCP was 2.5% more costly than TH-SCP in relative terms.

SCH-SCP was found to be more costly over a 10-year time horizon than TH-SCP in our study population.
