Objective : To examine factors that in(cid:976)luenced the revenues from Civil Servants Medical Bene(cid:976)it Scheme [CSMBS] of a Thai teaching
hospital.
Materials and Methods : Retrospective invoice data were retrieved from the hospital’s database to analyze changes between (cid:976)irst
half of (cid:976)iscal year 2016 and 2017 by the Laspeyres index. Effects of price and quantity of existing item, exiting item, and new item
were calculated for top six expense types and for total.
Results : CSMBS revenues were about two (cid:976)ifths of total hospital revenues. The revenues were from drug (22.3%) and from inpatient
[IP] and outpatient [OP] services (77.1%). The price, quantity, exiting item, new item, and cross effects in IP service were 0.09, 0.88,
-2.61, 2.77, and -0.13, while in OP service they were at -0.22, 1.66, -1.07, 0.69, and -0.05, respectively.
Conclusion : By splitting revenues into factors using Laspeyres index, each factor will re(cid:976)lect the increase or decrease of total revenue
and allow the administrative team to monitor hospital revenues.
