A Bibliometric Analysis of Diagnosis Related Groups from 2013 to 2022

Abstract

Purpose As an important management method of the global healthcare system, diagnosis related groups (DRGs) classify patients into different cost groups and pay more attention to the equitable distribution of medical resources and the quality of medical services. At present, most countries have used DRGs to help medical institutions and doctors to treat patients more accurately, avoid the waste of medical resources, and improve treatment efficiency. Methods The Web of Science database was searched to collect all relevant literature on DRGs from 2013 to 2022. The literature information was imported into CiteSpace, Vosviewer, and Histcite for data analysis and visualization of the results. Analyze the cooperative relationship among the countries, institutions, journals, and authors. The usage trend of keywords; Highlight the content of the cited articles. Results The number of articles published in this decade was stable, and the number of citations in 2014 was the highest. The United States and Germany, as the first countries to use the DRGs system, are ahead of other countries in terms of the number and quality of articles. We have carried out content research on the articles with high citations, and summarized the application range of DRGs; classification method; advantages and disadvantages of the application. In general, the development trend of DRGs in foreign countries is to continuously optimize the classification method, expand the scope of application, and improve the application effect. These provide support and reference for the improvement of medical services and the perfection of the medical insurance system. Conclusion The application of DRGs can improve the quality and efficiency of medical services, and reduce the waste of medical expenses. It can also promote the rational allocation of medical resources and the equity of medical services. In the future, DRGs will pay more attention to the personalized diagnosis and treatment and fine management of patients, and the sharing and standardization of medical data, to promote the development of medical informatization.

The reimbursement system can influence the treatment choice and favor joint replacement versus other less invasive solutions in patients affected by osteoarthritis

“…The reimbursement system is an essential element in the public healthcare context, as it ensures access to medical care for patients with health issues while managing the available resources [39]. The DRG has become an important classification system in the global healthcare frameworks, including Europe, America, Asia, and Australia [54, 58].…”

“…Diagnosis Related Groups (DRGs) represent a vital facet of medical insurance payment systems, meticulously considering various patient-related factors (Mathauer & Wittenbecher, 2013 ). By categorising patients into highly homogeneous groups with similar healthcare resource consumption patterns, DRGs demands for pharmacists including service capability, service efficiency, and quality safety, collectively fostering the rational use of pharmaceuticals within healthcare institutions (Lang et al, 2023 ; Sun et al, 2023 ). HCT has increasingly become an essential treatment option for many patients undergoing life-threatening haematologic illnesses (Muskens et al, 2023 ).…”

Exploring hot topics and evolutionary paths in the Diagnosis-Related Groups (DRGs) field: a comparative study using LDA modeling

“…To this end, numerous researchers have extensively reviewed the literature on DRGs based on bibliometric tools such as CiteSpace and VOSviewer. They have also summarized the research directions in DRGs worldwide through keyword clustering [ 12 , 13 ]. However, this method is limited to keywords, authors, and research institutions and cannot visually analyze the overall content of the text.…”
