An Integrated Cost Model Based on Real Patient Flow: Exploring Surgical Hospitalization

Abstract

Considering the gap observed in studies on health costs, this article aims to propose a cost calculation model for surgical hospitalization. A systematic literature review using PRISMA was conducted to map cost drivers adopted in similar studies and provide theoretical background. Based on the review, an integrated model considering real patient flow was developed using CHEERS guidelines. The micro-costing top-down method was adopted to develop the cost model allowing a balance between the accuracy of the information and the feasibility of the cost estimate. The proposed model fills two gaps in the literature: the standardization of a cost model and the ability to assess a vast number of different surgery costs in the same hospital. Flexibility stands out as an important advantage of the proposed model, as its application enables evaluation of elective and urgent surgeries of medium and high complexity performed in public and private hospitals. As a limitation, the hospital should have hospital information and cost systems implemented. The proposed cost model can provide important information that can result in better decision making. This becomes more relevant in public health, especially in low- and middle-income countries, which faces a lack of resources and whose positive effects can improve healthcare.

Cost Analysis of Hospitalization for COVID-19 in a Brazilian Public Teaching Hospital

“…Thus, all costs were allocated to the costs of the NIR, COVID-19 area, and examinations and then aggregated into 2 groups: “hospitalization costs” and “personnel costs” according to the model presented in Figure 1 . This cost calculation method was based on the model developed by Vieira et al 14 adapted for clinical admissions.…”
