Analysis of demand for closed incision negative pressure wound therapy: willingness to pay and risk perception

Abstract

CiNPWT is an advanced postoperative complication prevention method that helps reduce treatment costs and improve the quality of life for patients. To effectively implement ciNPWT prevention methods, understanding the demand and WTP of high-risk patients who are indicated to use it plays a crucial role in developing service packages and selecting suitable medical equipment for this service. Additionally, studying the factors related to patients' ciNPWT usage needs can significantly contribute to the development of quality improvement initiatives in hospitals. This study aims to measure the WTP and identify the factors influencing the WTP for ciNPWT. A cross-sectional study was conducted with 150 patients randomly divided into 5 groups, each corresponding to a different bid level ranging from 4,000,000 VND to 12,000,000 VND. The CVM was employed to determine the WTP for ciNPWT. This study utilized personal information and the Risk perception of medical help-seeking behavior questionnaire to identify the factors influencing patients' WTP for ciNPWT. The average price level for WTP for one ciNPWT treatment falls within the range of 1,500,000 VND to 5,800,000 VND. Level of bid, residence, individual total monthly income and level of stigma risks perception related to demand using ciNPWT (p-value < 0.05). The study helps determine the price that patients are willing to pay for ciNPWT and the factors related to patients' demand for its usage. Therefore, policymakers and healthcare system developers can refer to these findings to further develop and enhance the healthcare system in Vietnam.
