Publication Trends and Hot Spots in Chronic Postsurgical Pain (CPSP) Research: A 10-Year Bibliometric Analysis

Abstract

Aging populations and increasing quality of life requirements have attracted growing efforts to study chronic postsurgical pain (CPSP). However, a diverse range of factors are involved in CPSP development, which complicates efforts to predict and treat this disease. To advance research in this field, our study aimed to use bibliometric analysis to quantitatively and qualitatively evaluate CPSP research and predict research hot spots over the last 10 years. Methods: Relevant publications between 2011 and 2020 were extracted from the Web of Science Core Collection database. CiteSpace software (v5.7.R2) and the Online Analysis Platform of Literature Metrology were used to analyze research attributes including countries and authors, keywords and co-occurrence, and burst detection to predict trends and hot spots. Results: A total of 2493 publications were collected with the number of annual publications showing nearly threefold increase over the past decade. Articles were the primary publication type with the United States as the leading country and the center of national collaboration. Johns Hopkins University provided the leading influence within the CPSP field. Postoperative pain, multimodal analgesia, quality of life, opioid, microglia, cesarean delivery, inguinal hernia, chronification, genetic polymorphism, and lidocaine were the top 10 clusters in co-occurrence cluster analysis. Moreover, burst detection was shown that epidural analgesia, nerve injury, total hip arthroplasty were the new hot spots within the CPSP field. Conclusion: Bibliometric mapping not only defined the overall structure of CPSP-related research but its collective information provides crucial assistance to direct ongoing research efforts. The prominent keywords including "risk factor" and "multimodal analgesia" indicate that CPSP prevention and new treatment methods remain hot spots. Nonetheless, the recognition that CPSP is complex and changeable, proposes comprehensive biopsychosocial approaches are needed, and these will be essential to improve CPSP interventions and outcomes.

Trends of High-Impact Studies in Pharmacology and Pharmacy: A Cross-Sectional Study

“…In addition, the geographical distribution of these institutions indicated the same region or neighboring regions, which is consistent with previous studies in the nursing field (Zhu et al, 2020). The largest node of international collaborations was based on universities from England, Australia, the USA, and China, suggesting that international collaborations were critical in the top studies of such fields, which was consistent with the results of many studies (Chong et al, 2021;Li et al, 2021;Zhang S. et al, 2021). This indicates that the academic capacity of an institution is positively related to its cooperative relationship (Chong et al, 2021;Li et al, 2021;Zhang S. et al, 2021).…”

Incidence and risk factors for chronic postsurgical pain following video-assisted thoracoscopic surgery: a retrospective study

“…The reported rates of CPSP after VATS varies widely, such a difference between studies may be related to the methodology (uni-portal vs. multi-portal VATS), perioperative analgesia regimen and CPSP definition. Additionally, “risk factor” has been a hot spot in the field of CPSP research in recent 10 years [ 12 ]. Surgical procedure, age, physical health, mental health, preoperative pain in the surgical field and another area have been proved to be risk factors for the occurrence of CPSP after several surgical procedures [ 13 , 14 ].…”

Scientific Knowledge Graph and Trend Analysis of Central Sensitization: A Bibliometric Analysis

“…It is well known that in recent years there had been a significant increase in the number of publications in the field of pain, such as pain after spinal cord injury, 37 chronic postsurgical pain, 38 etc. As shown in Figure 1 , the number of CS-related articles was on a very steady upward trend, which indicated a great potential for future development.…”
