A Bibliometric Analysis of Published Literature in Postoperative Pain in Elderly Patients in Low- and Middle-Income Countries

Postoperative pain (POP) remains a major challenge for surgeons and anesthesiologists worldwide, especially in low- and middle-income countries. Elderly patients are at higher risk for undertreatment of pain. Despite that, there is a paucity of papers addressing POP among this population in developing countries. This study aimed to provide a bibliometric analysis of the literature concerning postoperative pain in elderly patients from low- and middle-income countries. It was performed an extensive search of papers on this subject through the Web of Science and Scopus database using a series of uniterms and, including publications from 2001 to 2021. Publication quality was assessed by using total citation frequency, average citations per item and other citation indexes. Citation indexes were low, with the highest reaching 15 citations. In conclusion, few studies of postoperative pain in the elderly in countries with medium and low income, indicating a need that has not yet been met for this population and in these areas of the world. The published studies were not specifically aimed at the elderly, had limited impact, low international visibility. They were not epidemiological studies and are not robust, weakening knowledge and decision-making towards policies directed at this vulnerable population.
