The magnitude and associated Factors of Postoperative Trichiasis among adults who underwent Trachomatous Trichiasis Surgery in Ambassel District, North-East Ethiopia
Abstract Background In Trachoma endemic countries, many people who underwent Trichiasis surgery faced a recurrence of the disease. Postoperative Trichiasis is a significant problem for patients and health care providers because it puts the eye at renewed risk of sight loss. Despite the low utilization of Trachomatous Trichiasis (TT) surgery and high recurrence rate, evidences that elucidate why TT recurs after surgery are limited. This study was aimed to assess the magnitude and associated factors of postoperative Trichiasis among 18 years and above individuals who underwent Trachomatous Trichiasis surgery between 2006 and 2011 Ethiopian Fiscal year in Ambassel District, North-East Ethiopia, 2020. Methods The community-based cross-sectional study design was conducted from March 10 to March 23/2020 in selected kebeles of Ambassel District. The required sample size was calculated using EPI-INFO Version 7. A multi-stage sampling technique was used to employ a total of 506 individuals. Data were collected through the interviewer-administered structured pre-tested questionnaire and entered into EpiData version 3.1 and then exported to SPSS version 23.0. Bi-variable and multivariable logistic regression models were fitted to identify associated factors of Trachomatous Trichiasis recurrence. Results Four hundred ninety two individuals participated in this study with response rate of 97.2%. In Ambassel district the prevalence of postoperative Trichiasis was 23.8% (95%CI = 19.9–27.8). Among associated factors of postoperative Trichiasis age 50–59 AOR = 3.34 (CI = 1.38–8.1), 60–69 AOR = 3.24(CI = 1.38–7.61), ≥ 70 years AOR = 6.04 (CI = 2.23–16.41), duration since surgery AOR = 1.7(CI = 1.35–2.14), complication AOR = 2.98(CI = 1.24–7.2), washing the face two times AOR = 0.25(CI = 0.13–0.47), washing the face three and more times AOR = 0.1(CI = 0.41 − 0.25), taking Azithromycin following surgery AOR = 0.19(CI = 0.09–0.41), pre-operative epilation history AOR = 2.11, (CI = 1.14, 3.9)and having a knowledge about TrachomaTtrichiasis AOR = 0.21(CI = 0.08–0.58) showed a statistical significant association. Conclusions The prevalence of postoperative Trichiasis in Ambassel District was higher than most Ethiopian studies. Age, frequency of face washing, medication following surgery, duration since the last surgery, knowledge about trachoma, pre-operative epilation history and complication after surgery were identified to be independent factors. To minimize postoperative Trichiasis stakeholders need to consider health education for patients, provision of Azithromycin after surgery and proper training for IECWs.
