Evaluation of post-tracheostomy scars and their impact on persons' quality of life: A case-control study

Tracheostomy is one of the more commonly performed procedures in critically ill patients under mechanical ventilation. Postoperative scarring is one of the bothersome sequelae of tracheostomies. Scars distort physical appearance, especially when found on the head and neck, which could have a negative impact on quality of life. The aim of this study was to evaluate and assess the impact of post-tracheostomy scars on quality of life according to the tracheostomy method. A prospective, single-center, observational, case-control study was conducted. One hundred fifty-six persons with a post-tracheostomy surgical scar for more than four months were observed using the Patient and Observer Scar Assessment Scale and Dermatology Life Quality Index questionnaire. Persons were divided into two groups depending on the method of tracheostomy, and the duration of the cannulated period was considered in both groups. Statistical analyses were performed using SPSS ver. 16.0 (SPSS Inc., Chicago, IL, USA), and P values of <0.05 were considered significant. The patients who had a tracheostomic tube cannulation period of fewer than 15 days had better cosmetic results than those who had tracheostomic tubes for more than 15 days, regardless of the tracheostomy method: 6.64 +/- 0.082 versus 16.15 +/- 0.096 (P < 0.001) in the surgical tracheostomy group and 7.26 +/- 0.211 versus 14.17 +/- 0.379 (P < 0.05) in the percutaneous dilatational group. The Dermatology Life Quality Index scores had a mean value of 0.6 +/- 0.01, which means that post-tracheostomy scarring in the present study had no effect on the person's quality of life. The aesthetic outcomes of post-tracheostomy scars after the open surgical tracheostomy technique did not significantly differ from those of the percutaneous dilatational technique in the present study. Persons with a long duration of tracheostomic tube ventilation showed worse aesthetic outcomes than those with short-term tracheostomic cannulation, which was not dependent on the tracheostomy technique. The Dermatology Life Quality Index showed that post-ttracheostomy scarring in the present study had no effect on the person's quality of life.

Automated summary

This study aimed to evaluate and assess the impact of post-tracheostomy scars on quality of life. The results showed that patients with a tracheostomic tube cannulation period of fewer than 15 days had better cosmetic results than those with tracheostomic tubes for more than 15 days. The Dermatology Life Quality Index scores indicated that post-tracheostomy scarring in this study had no effect on the person's quality of life.
