A follow-up study of adults with suicidal burns: psychosocial adjustment and quality of life

Long-term mortality after self-inflicted burns

BACKGROUND

Those with self-inflicted burns are a small but consistent group among burn patients, with large injuries and conflicting findings regarding their in-hospital mortality. Overall, burn survivors have a shorter life expectancy, as compared with national controls, but long-term mortality after self-inflicted burns is understudied. The aim of this retrospective study was to investigate possible differences in long-term mortality among survivors after self-inflicted and accidental burns.

METHODS

All adult patients with burns admitted at the Linköping Burn Centre and discharged alive between 2000 and 2017 were included, and end of follow up was April 26, 2021. Those with unknown survival status at that time were excluded. A Cox proportional hazards regression model, adjusted for age and sex, was used to analyse long term mortality.

RESULTS

Among the 930 patients included in this study, 37 had self-inflicted burns. Overall, median follow up period was 8.8 years and crude mortality was 24.7%. After adjustment for age and sex, self-inflicted burns were independently associated with long-term mortality, Hazard Ratio= 2.08 (95% CI 1.13-3.83). Post hoc analysis showed that the effect was most pronounced during the first years after discharge although it was noticeable over the whole study period.

CONCLUSION

Long-term risk of mortality after discharge from a burn centre was higher in patients with self-inflicted burns than in patients with accidental burns. The effect was noticeable over the whole study period although it was most pronounced during the first years after discharge.

"Reverse tensor fascia latae perforator flap for reconstruction of knee defect: Anatomic study by computed tomographic angiography and a case report"

BACKGROUND

Reverse anterolateral thigh perforator (ALTp) pedicle flap can be used to reconstruct perigenicular defect thanks to the anastomoses between the descending branch of the lateral circumflex femoral artery (LCFA) and the perigenicular network. In a few cases, however, patients do not present any ALTp. We hypothesized that, in such cases, an adjacent perforator, the tensor fascia latae perforator (TFLp), emerging from the LCFA ascending branch, could be used instead. To assess the feasibility of this technique, a radiological study was conducted. A first patient was treated using this option.

METHODS

Sixty lower limb computed tomography were analyzed. The first treated patient was a 50-years-old man suffering from a 5-mm chronic bone exposure and osteomyelitis. Other reconstructive options were not indicated since he presented a multiscarry leg, severe arteriopathy, and no ALTp. A TFLp flap was raised, and the LCFA ascending and descending branches were dissected in continuity. After ligation of the LCFA, the blood flow reversed in the descending branch to irrigate the flap through the ascending branch.

RESULTS

A TFL perforator was observed in all the cases of the radiological study. The LCFA branching pattern was compatible with achieving a reverse TFL perforator flap in 43 cases (72%). The average pedicle length was 32 cm (22-38 cm). In the first clinical case, the flap covered the defect easily. After three months, the patient showed no evidence of infection recurrence and recovered a painless walk.

CONCLUSION

The reverse TFLp flap can be a suitable option for perigenicular reconstruction.

The effect of self-inflicted burns on ABSI score prediction power: A four-year prospective multicenter study of the German Burn Registry

BACKGROUND

Suicide attempted by self-inflicted burns are associated with lower survival rates compared to accident related burns.

OBJECTIVE

We investigate the relation between self-inflicted burns (SIB) and survival rates and how this relation is moderated by variables used to predict survival rates in the ABSI score, a widely used measure. Additionally, we compare the predicted survival rates by the ABSI score to the actual rates in our sample for SIB and accident patients.

METHODS

In this prospective multicenter study data from the German Burn Registry are statistically analyzed using two sided t-test and multivariate linear regression models.

RESULTS

5330 patients (214 with SIB) met our inclusion criteria. We find a 6.8 percentage points lower survival rate for patients with SIB when we control for patient condition with the five ABSI components as covariates. These higher mortality rates can be explained by the higher rate of therapy restrictions for patients with self-inflicted burns. Additionally, different ABSI modifications can improve the predictive power of the score.

CONCLUSION

Patients with SIB have lower survival rates compared to accident patients. Recently proposed modifications of the ABSI score can improve the accuracy of survival rate prediction for SIB.

Suicidality After Burn Injuries: A Systematic Review

Burn survivors may be at increased risk for suicide due to the nature of their injury and psychiatric comorbidities. The purpose of this review is to assess the evidence as to the prevalence of suicidal ideations and behaviors (attempts and completed suicides) in burn survivors as well as evaluate risk and protective factors. PubMed, EMBASE, CINAHL, Cochrane, PsycINFO, and Web Science databases were searched using search terms regarding suicide, suicidality, and burn. Fourteen full-text manuscripts and two published abstracts were included in the review. Overall, burn survivors demonstrate elevated suicidal ideations and a higher lifetime prevalence of suicide attempts compared to the general population. There is mixed evidence as to rates of completed suicide postburn injury, though rates appear to be relatively low. Risk factors include pain at discharge, perceived level of disfigurement, premorbid psychiatric comorbidities, and past suicide attempts. Results of this systematic review shed light on the scarcity of data on rates of suicidality among burn survivors, which is surprising given the multiple risk factors burn survivors possess including chronic pain, sleep disturbances, history of substance abuse, posttraumatic stress disorder, social isolation, and depression which are linked to suicidality in the general population. Suicide risk screening should be included as an integral part of burn survivors' care, and more research is needed to better understand the magnitude of this phenomenon and offer targeted interventions to vulnerable individuals.

Health related quality of life in adults after burn injuries: A systematic review

OBJECTIVES

Measurement of health-related quality of life (HRQL) is essential to qualify the subjective burden of burns in survivors. We performed a systematic review of HRQL studies in adult burn patients to evaluate study design, instruments used, methodological quality, and recovery patterns.

METHODS

A systematic review was performed. Relevant databases were searched from the earliest record until October 2016. Studies examining HRQL in adults after burn injuries were included. Risk of bias was scored using the Quality in Prognostic Studies tool.

RESULTS

Twenty different HRQL instruments were used among the 94 included studies. The Burn Specific Health Scale-Brief (BSHS-B) (46%), the Short Form-36 (SF-36) (42%) and the EuroQol questionnaire (EQ-5D) (9%) were most often applied. Most domains, both mentally and physically orientated, were affected shortly after burns but improved over time. The lowest scores were reported for the domains 'work' and 'heat sensitivity' (BSHS-B), 'bodily pain', 'physical role limitations' (SF-36), and 'pain/discomfort' (EQ-5D) in the short-term and for 'work' and 'heat sensitivity', 'emotional functioning' (SF-36), 'physical functioning' and 'pain/discomfort' in the long-term. Risk of bias was generally low in outcome measurement and high in study attrition.

CONCLUSION

Consensus on preferred validated methodologies of HRQL measurement in burn patients would facilitate comparability across studies, resulting in improved insights in recovery patterns and better estimates of HRQL after burns. We recommend to develop a guideline on the measurement of HRQL in burns. Five domains representing a variety of topics had low scores in the long-term and require special attention in the aftermath of burns.

Attempted suicide by self-immolation is a powerful predictive variable for survival of burn injuries

Up to 9% of all burn victims in western countries are reported to have been caused by self-immolation with suicidal intent and usually involve extensive injuries. The authors sought to identify differences between suicide burn victims as opposed to those who sustained their injuries accidentally with regard to injury severity and mortality and determine the possible impact of suicide as a prognostic variable in the context of a scoring system such as the Abbreviated Burns Severity Index (ABSI). The data of all burns patients treated at the Specialist Burns Intensive Care Unit, University Hospital Zürich, between 1968 and 2008 were analyzed retrospectively. Of the 2813 patients included in the study, 191 were identified as attempted suicides, most commonly involving the use of accelerants. Thirty percent of all suicide victims had preexisting psychiatric diagnoses. Suicide victims presented with significantly more extensive burns (53.7%, ±0.98 SEM vs 21.4 %, ±0.36 SEM, P < .0001), had higher total ABSI scores (8.4, ±0.23 SEM vs 6.6, ±0.05 SEM, P < .0001), and had higher mortality rates (42.9% [83/191] vs 16.3% [426/2622]) than accident victims. Furthermore, logistic regression revealed suicide to be a significant predictor of mortality as inhalation injury (odds ratio 2.2, 95% confidence interval 1.4-3.5, P < .0003 and odds ratio 2.4, 95% confidence interval 1.4-4.0, P < .0009, respectively). The odds of dying from an attempted suicide are twice as high compared with those of accident patients in the same ABSI category, making suicide a powerful predictor of mortality. The authors therefore suggest including it as a fixed variable in scoring systems for estimating a patient's mortality after burn injuries such as the widely used ABSI.

Epidemiology and outcome analysis of severe extensive burns: a 12-year summary of 103 cases in a burn center in China

The purpose of this article is to improve the treatment of severe extensive burns (SEB) patients by summarizing treatment experience in recent 12 years in China and analyzing the follow-up quality of life (QOL) in these patients. Clinical data and rescue measures of 103 SEB patients (≥70% TBSA) admitted in a burn center in Shanghai between 1997 and 2009 were reviewed, and QOL and hand function of those who survived more than 2 years were assessed by Brief Version of Burn Specific Health scale-B and Michigan Hand Outcome Questionnaire. Of these, 76.7% were caused by flames and 15.5% caused by scald. The median burn area was 87.5% (interquartile range, 77.0-95.0%) TBSA, of which third-degree burns accounted for 56.5% (interquartile range, 25.8-80.0%) TBSA; 71.8% were complicated by inhalation injury. The occurrence of in-hospital complications was 75.7%, with the respiratory system complications predominating (49.5%). The fatality rate was 28.2%, mainly due to sepsis and multiple organ dysfunction syndrome. Work, body image, and heat sensitivity got the lowest Brief Version of Burn Specific Health scale-B scores in all nine domains, and Michigan Hand Outcome Questionnaire scores were also relatively poor. Flame burns remain to be the main cause of SEB in China in recent 12 years. Treatment is still challenged because of the depth and extensive burn area and high occurrence of multiple system complications. How to ameliorate QOL of SEB patients, intensify the functional rehabilitation, and improve their physical appearance in particular remain to be a crux.
