Current status and influencing factors of loss to follow-up among moderate to severe chronic periodontitis patients with long-term periodontal therapy / 中国实用护理杂志

ABSTRACT

Objective:To investigate and analyze the current status and influencing factors of loss to follow-up among moderate to severe chronic periodontitis patients with long-term periodontal therapy.Methods:A total of 196 patients with moderate to severe chronic periodontitis receiving treatment from January 2016 to June 2017 were recruited by convenient sampling. A self-developed Clinical and Demographic Questionnaire, Self-efficacy Scale for Self-care (SESS), Dental Fear Scale (DFS) were used to obtain data at baseline. The outcome of loss to follow up within 20 months after the initial treatment of periodontitis was further recorded. Multivariate Logistic regression analysis was conducted to identify the influencing factors of loss to follow-up in patients with long-term periodontal therapy.Results:112 of 196 patients were lost during follow-up period(observation group), and 84 patients were lost during follow-up period (control group). Compared with control group, there were significant differences in age [(47.8±9.8) years vs. (42.2±11.2)years, t value was 6.672], education level[≤college 23.2% (26/112) vs.13.1%(11/84), χ2 value was 5.033], disease severity [moderate53.6% (60/112) vs.34.5% (29/54), χ2 value was 9.027], the proportion of patients undergoing periodontal surgery [4.5% (5/112) vs. 23.8% (20/84) χ2 value was 8.264], the low-level of self-efficacy for self-care [53.6% (60/112) vs. 6.0% (5/84), χ2 value was 18.992] and the score of SESS (52.6±8.2 vs. 62.9±7.1), t value was 5.996] in observation group ( P<0.05) . Multivariate logistic regression analysis showed that the risk factors of loss to follow-up in chronic periodontitis patients with long-term periodontal therapy included age increase ( OR=1.043, 95% CI 1.013-1.085, P=0.007), moderate disease severity ( OR=4.894, 95% CI 2.291-10.588, P<0.01), non-surgical treatment ( OR=11.356, 95% CI 2.236-27.483, P=0.004), low-level self-efficacy for oral self-care ( OR= 31.884, 95% CI 20.812-56.173, P<0.01). Conclusions:Age, severity of periodontitis, the way of periodontal treatment and the level of self-efficacy for oral self-care are influencing factors of loss to follow-up in chronic periodontitis patients with long-term periodontal therapy.
