Abstract:
Objective:To investigate the pain status in diabetic foot ulcer (DFU) patients and analyze its influencing factors.Methods:A single-center cross-sectional survey research method was used. From May 2021 to February 2022, DFU patients who were admitted to the Fourth Medical Center of PLA General Hospital and met the inclusion criteria were selected and investigated. The scores of the heaviest pain, the least pain, the average pain, and the current pain in pain degree and the total score and the scores of influence on patients' daily life, mood, walking ability, daily work, relationship with others, sleep, and life interest in pain-related effects and the total score of patients were evaluated by the brief pain inventory. A self-designed general data questionnaire was used to collect the data including patients' gender, age, education level, body mass index, self-care ability, diabetes course, wound Wagner grade, bacterial culture result of wound specimen, and the levels of glycated hemoglobin, albumin, prealbumin, hemoglobin, and leukocyte count. Patients were classified according to general data, and the total scores of pain degree and pain-related effects were counted. Data were statistically analyzed with Kruskal-Wallis test and Mann-Whitney U test. The indicators with statistically significant differences in univariate analysis were selected for generalized linear model analysis to screen the independent risk factors of pain severity and pain-related effects in DFU patients. Results:A total of 44 questionnaires were sent out, and 42 valid questionnaires were collected, with effective recovery of 95.45%. The scores of the heaviest pain, the least pain, the average pain, and the current pain in DFU patients were 5 (0, 10), 2 (0, 6), 3 (0, 8), and 2 (0, 8), respectively, and the total score of the pain severity was 11 (0, 24); the scores of pain-related effects on patients' daily life, mood, walking ability, daily work, relationship with others, sleep, and life interest were 4 (0, 10), 4 (0, 10), 5 (0, 10), 5 (0, 10), 3 (0, 10), 4 (0, 10), and 4 (0, 10), respectively, and the total score of pain-related effects was 30 (0, 63). In 42 DFU patients, most patients were male, aged 39-87 (67±10) years, most patients had education level of junior high school, most patients had diabetes for more than 20 years, half of patients' wounds were Wagner grade 4, most patients had body mass index and leukocyte count within normal limits, most patients had partial dependence on self-care ability, the bacterial culture results of wound specimen in the vast majority of patients were positive, about half of the patients had abnormal level of albumin, and most patients had abnormal levels of glycosylated hemoglobin, prealbumin, and hemoglobin. Univariate analysis of the above general data showed that total scores of pain severity among patients with different hemoglobin levels and leukocyte counts were statistically significant different (with Z values of -2.05 and -2.55, respectively, P<0.05), and the total scores of pain-related effects on patients with different hemoglobin levels, leukocyte counts, and bacterial culture results of wound specimen were statistically significant different (with Z values of -2.66, -2.02, and -2.12, respectively, P<0.05). Generalized linear model analysis showed that leukocyte count was an independent risk factor for pain severity and pain-related effects in 42 DFU patients (with 95% confidence intervals of 0.28-11.87 and 5.67-36.99, respectively, standardized regression coefficient values of 6.17 and 21.33, respectively, both P values <0.05). The bacterial culture result of wound specimen was an independent risk factor for pain-related effects in 42 DFU patients (with 95% confidence interval of 2.92-39.09, standardized regression coefficient value of 21.00, P<0.05). Conclusions:DFU patients often suffer pain, and the bacterial culture results of wound specimen and leukocyte count are the main factors affecting the pain of DFU patients.
