[A cross-sectional study on the current status and influencing factors of kinesiophobia in adult burn patients].

Abstract

Objective: To investigate the current status and influencing factors of kinesiophobia in adult burn patients. Methods: A single center cross-sectional study was conducted. A total of 170 adult burn patients, meeting the inclusion criteria, were admitted to the Department of Plastic Surgery and Burns of the West China Hospital of Sichuan University from October 2018 to December 2019. On admission, the self-made general information questionnaire was used to investigate the gender, age, education level, marital status, payment method of medical expenses, injury factors, and total burn area of patients. One month after admission or before discharge, the presence and degree of kinesiophobia of patients were evaluated by the Tampa Scale for Kinesiophobia (TSK), the pain degree at the time of burn, debridement and dressing change, after burn operation, and at rest (the mean value was taken as the result) of patients was evaluated by the Visual Analogue Scoring, the social support level of patients was evaluated by the Social Support Revalued Scale, and the degree of anxiety and depression of patients was evaluated by the Hospital Anxiety and Depression Scale. According to the TSK score, the patients with score >37 points were included into kinesiophobia group, and the patients with score≤37 points were included into non-kinesiophobia group. The general information of patients in the two groups, as well as the pain score, social support level score, anxiety score, and depression score mentioned above, were recorded. Data of patients between the two groups were statistically analyzed with unifactor analysis including chi-square test, independent sample t test, and Mann-Whitney U test. The factors with statistically significant differences in unifactor analysis were used as variables for multivariate logistic regression analysis to screen out influencing factors of kinesiophobia in adult burn patients. Results: Questionnaires and scales of 170 patients were collected, and the recovery rate was 100%. The data of two patients complicated with cranial fracture aggravation were removed, and 168 valid data were obtained, with the effective rate of 98.82%. Among the 168 patients, 88 were male (52.38%) and 80 were female (47.62%), aged from 18 to 71 (41±6) years. Most of the patients had secondary school education or below, were married, and with no out-of-pocket medical expenses. The main factors of injury were flame and hydrothermal fluid, and the total burn area was 2%-75% ((28±5)%) total body surface area. The TSK score was (41±5) points, the pain score was 4.0 (2.6, 5.0) points, the social support level score was (40±5) points, the anxiety score was 8.5 (7.0, 13.0) points, and the depression score was 9.5 (6.5, 12.0) points. A total of 98 patients had kinesiophobia, and the incidence of kinesiophobia was 58.33%. There was no statistically significant difference in gender, age, educational level, marital status, injury factors of patients between kinesiophobia group and non-kinesiophobia group (P>0.05). The percentage of out-of-pocket expenses, total burn area, pain score, anxiety score, and depression score of patients in kinesiophobia group were significantly higher than those in non-kinesiophobia group (χ2=6.402, t=2.39, -8.05, Z=-6.68, -7.89, P<0.05 or P<0.01), and the social support level score of patients in kinesiophobia group was significantly lower than that in non-kinesiophobia group (t=5.22, P<0.01). The multivariate logistic regression analysis showed that total burn area, pain score, social support level score, anxiety score, and depression score were the independent influencing factors for the development of kinesiophobia in adult burn patients (odds ratio=1.79, 1.45, 0.78, 1.15, 1.17, 95% confidence interval=0.80-0.92, 1.24-1.74, 0.65-0.91, 1.06-1.29, 1.03-1.24, P<0.01). Conclusions: The incidence of kinesiophobia in adult burn patients is high, and the degree of kinesiophobia is mainly affected by total burn area, pain, social support level, anxiety and depression degree and so on, thus these factors need to be considered when designing interventions to reduce the incidence and degree of kinesiophobia.
