Abstract: Objective: To develop a comprehensive, scientific integrated pain assessment scheme, aiming to provide support for clinical healthcare professionals in conducting effective pain assessments. Methods: Through literature research, a preliminary comprehensive assessment scheme for pain was formulated. From February to March 2025, 15 experts in clinical medicine, nursing, pharmacy, psychology, and management were invited to conduct an expert letter consultation on the proposed comprehensive assessment scheme. Through this consultation, the final comprehensive pain assessment scheme was established. Results: Two rounds of expert letter consultations were conducted. The questionnaire recovery rates were 93.8% and 100.0% respectively; the authority coefficients were 0.957 and 0.971 respectively; the Kendall's concordance coefficients were 0.331 and 0.337 (P<0.001). The finalized comprehensive pain assessment scheme includes five aspects: general information, pain-related dimensions, physiological/biological dimensions, psychological dimensions, and social dimensions, with a total of 31 items. Conclusion: The comprehensive pain assessment scheme developed in this study is practical, scientific and professional. It contributes to improve the assessment efficiency for pain patients, and thus provide support for enhancing the nursing quality and treatment effects of pain patients.
