Psychiatric outcomes amongst adult survivors of childhood burns

Gender differences in relation to stigmatization and depressive symptoms after burns

OBJECTIVES

The aim of this study was to investigate the moderating role of gender in the relationship between burn severity, perceived stigmatization and depressive symptoms at multiple time points postburn.

MATERIALS AND METHODS

This multi-center study included data from two cohorts. Cohort 1 consisted of 215 burn survivors, participating in a longitudinal study with measures at 3 and 12 months postburn. Cohort 2 consisted of 180 burn survivors cross-sectionally assessed at 5 - 7 years postburn. Both cohorts completed self-reported measures of perceived stigmatization and depressive symptoms. The number of acute surgeries (i.e., no surgery, 1 surgery or 2 or more surgeries) was used as indicator of burn severity. Relations between number of surgeries, depressive symptoms, and perceived stigmatization, including possible indirect effects, were evaluated with gender-specific path models.

RESULTS

In both men and women, number of surgical operations was related to higher levels of depressive symptoms and perceived stigmatization at 3 months after burn. In women, number of operations was still directly related to both constructs at 12 months after burn, which was cross-sectionally confirmed in the 5-7 years after burn cohort. In men, from 3 to 12 months after burn, depressive symptoms and perceived stigmatization were bidirectionally related, and, through these effects, number of surgeries was indirectly related to both outcomes. In the cross-sectional 5-7 years after burn cohort, number of operations was related to stigma but not to depressive symptoms of men.

CONCLUSION

Number of operations had a different effect on psychosocial adaptation of male and female burn survivors. In women, a persistent direct link from number of operations to both depressive symptoms and perceived stigmatization was found over time. In men, the effect of number of operations was most evident in the short-term, after which perceived stigmatization and depressive symptoms became interrelated. This indicates that burn severity remains a factor of significance in psychological adjustment in women, whereas in men, this significance seems to decrease over time.

Impact of childhood burns on academic performance: a matched population-based cohort study

OBJECTIVE

This study aimed to compare academic performance and high school completion of young people hospitalised for a burn compared with young people not hospitalised for an injury.

DESIGN

A retrospective population-based matched case-comparison cohort study.

PARTICIPANTS

Young people aged ≤18 years hospitalised for a burn during 2005-2018 in New South Wales, Australia, with age, sex and residential postcode-matched peers not hospitalised for any injury during 1 July 2001 and 31 December 2018.

MAIN OUTCOME MEASURES

Performance below the national minimum standard (NMS) on the National Assessment Plan for Literacy and Numeracy assessments and not completing high school.

RESULTS

Young females hospitalised for a burn had a 72% higher risk of poorer reading compared with their peers (adjusted relative risk (ARR) 1.72; 95% CI 1.33 to 2.23), while young males hospitalised with a burn showed no higher risk (ARR 1.14; 95% CI 0.91 to 1.43). Young males (ARR 1.05; 95% CI 0.81 to 1.35) and females (ARR 1.34; 95% CI 0.93 to 1.94) hospitalised with a burn had no higher risk of not reaching the NMS for numeracy compared with peers. Young people hospitalised with a burn had at least twice the risk of not completing year 10 (ARR 3.86; 95% CI 1.68 to 8.86), year 11 (ARR 2.45; 95% CI 1.89 to 3.18) and year 12 (ARR 2.09; 95% CI 1.63 to 2.67) compared with matched counterparts.

CONCLUSIONS

Young females hospitalised with a burn displayed poorer academic performance for reading compared with matched peers, while males and females were more likely to leave school earlier. Identifying unmet learning support needs of young burn survivors should be investigated.

Long-term Pain Symptomatology in PICU Survivors Aged 8-18 Years

BACKGROUND AND OBJECTIVES

Children discharged from the PICU often experience long-term physical, psychological, social and cognitive challenges, described as postintensive care syndrome. This study fills a critical gap by describing the long-term pain symptoms many children experience using child self-report.

METHODS

Participants in this cross-sectional study were children aged 8 to 18 years (and 1 parent, n = 64 dyads) who were 8 to 24 months post-PICU discharge. Participants completed measures assessing pain, psychosocial function, and treatment utilization. Health information relevant to the PICU admission was obtained from the electronic medical record.

RESULTS

Children were an average age of 14.3 years and 50% female. Average pain intensity in the past month was 3.65 (0-10 numeric rating scale), with 36% of children reporting pain ≥2 to 3 days a week. Youth with higher intensity (≥4) and more frequent pain (≥2-3 days a week) had greater pain catastrophizing, pain-related fear, anxiety, and sleep disturbance than those with less frequent and intense pain. Higher pain frequency was also associated with greater pain-related disability and depressive symptoms. Pain was not associated with any PICU-related variables abstracted from the electronic medical record. Parents reported children frequently accessed pain treatment services postdischarge; however, 37.5% reported the coronavirus disease 2019 pandemic impacted access to recommended services.

CONCLUSIONS

A significant portion of children experience pain post-PICU discharge. For many of these children, pain is frequent and is associated with impairments in psychosocial function. Future prospective research studies can be used to identify risk factors of poor pain outcomes so children can receive targeted interventions.

The psychological impact of paediatric burn injuries: a systematic review

OBJECTIVE

To review and synthesise qualitative literature regarding the psychological outcomes following paediatric burn injuries, and to determine if children and adolescents who experience a burn injury have elevated risk of psychopathology following the injury.

DESIGN

Systematic review of quantitative and qualitative studies.

DATA SOURCES

Informit health, Medline, Embase, and PsycINFO were searched from January 2010 to December 2020.

DATA EXTRACTION AND SYNTHESIS

Two reviewers screened articles, and one reviewer extracted data (with cross-checking from another reviewer) from the included studies and assessed quality using an established tool. Narrative synthesis was used to synthesise the findings from the quantitative studies, and thematic synthesis was used to synthesise the findings of included qualitative studies.

RESULTS

Searches yielded 1240 unique titles, with 130 retained for full-text screening. Forty-five studies from 17 countries were included. The psychological outcomes included in the studies were mental health diagnoses, medication for mental illness, depression, anxiety, stress, fear, post-traumatic stress, post-traumatic growth, emotional issues, self-harm, self-esteem, self-concept, stigmatisation, quality of life, level of disability, resilience, coping, and suicidality.

CONCLUSIONS

Our findings highlight paediatric burn patients as a particularly vulnerable population following a burn injury. Studies suggest elevated anxiety and traumatic stress symptoms, and higher rates of psychopathology in the long-term. Further research is recommended to determine the psychological outcomes in the other mental health domains highlighted in this review, as findings were mixed. Clinical care teams responsible for the aftercare of burn patients should involve psychological support for the children and families to improve outcomes.

Posttraumatic stress disorder prevalence in medical populations: A systematic review and meta-analysis

OBJECTIVE

PTSD is increasingly recognized following medical traumas although is highly heterogeneous. It is difficult to judge which medical contexts have the most traumatic potential and where to concentrate further research and clinical attention for prevention, early detection and treatment. The objective of this study was to compare PTSD prevalence in different medical populations.

METHODS

A systematic review of the literature on PTSD following medical traumas was conducted as well as a meta-analysis with final pooled result and 95% confidence intervals presented. A meta-regression was used to investigate the impact of potential effect modifiers (PTSD severity, age, sex, timeline) on study effect size between prevalence studies.

RESULTS

From 3278 abstracts, the authors extracted 292 studies reporting prevalence. Using clinician-administered reports, the highest 24 month or longer PTSD prevalence was found for intraoperative awareness (18.5% [95% CI=5.1%-36.6%]) and the lowest was found for epilepsy (4.5% [95% CI=0.2%-12.6%]). In the overall effect of the meta-regression, only medical events or procedures emerged as significant (p = 0.006) CONCLUSION: This review provides clinicians with greater awareness of medical contexts most associated with PTSD, which may assist them in the decision to engage in more frequent, earlier screening and referral to mental health services.

A review of potential biomarkers for assessing physical and psychological trauma in paediatric burns

Biological markers that evaluate physical healing as well as psychological impact of a burn are essential for effective treatment of paediatric burns. The objective of this review is to summarize the evidence supporting the use of biomarkers in children with burns. An extensive review of the literature was performed using PubMed. A total of 59 biomarkers were identified relating to burn presence, specifically relating to processes involved in inflammation, wound healing, growth and metabolism. In addition, biomarkers involved in the stress response cascade following a burn trauma were also identified. Although many biomarkers have been identified that are potentially associated with burn-related physical and psychological trauma, an understanding of burn biology is still lacking in children. We propose that future research in the field of children’s burns should be conducted using broad screening methods for identifying potential biomarkers, examine the biological interactions of different biomarkers, utilize child-appropriate biological fluids such as urine or saliva, and include a range of different severity burns. Through further research, the biological response to burn injury may be fully realized and clinically relevant diagnostic tests and treatment therapies utilizing these biomarkers could be developed, for the improvement of healing outcomes in paediatric burn patients.

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.

Psychosocial Interventions Targeting Recovery in Child and Adolescent Burns: A Systematic Review

Children post-burn injury experience a range of psychosocial sequelae that benefit from early provision of psychosocial support. However, no systematic review exists evaluating the full range of psychological interventions.

OBJECTIVE

To critically evaluate psychosocial interventions for children (<18 years old) with burn injuries in improving psychosocial recovery.

STUDY DESIGN

All-language studies were identified from inception to March 2018 in six electronic databases and appraised according to PRISMA checklist and Cochrane Risk of Bias Tool for quality. Studies were stratified into three groups: distraction (virtual reality, child life therapy, imagery-based therapy, hypnosis), burn camps, and other (social skills, cognitive behavioral therapy, parent group counseling).

RESULTS

Out of a total of 5,456 articles identified, 297 underwent full review resulting in 27 included articles published between 1986 and 2018. Sample sizes ranged from 9 to 266, comprising child and adult participants. A range of interventions and psychosocial outcome measures were found. Several studies (n = 21) reported statistically significant improvements in outcome; the majority were distraction interventions to reduce pain and anxiety. A limited number of studies showing effect was found for cognitive behavioral therapy and parent counseling. Risk of bias was high in studies of burn camps and mixed for all other interventions.

CONCLUSIONS

A range of psychosocial interventions and outcome tools exist in pediatric burns. Distraction interventions prior to and/or during dressing changes or physical therapy were shown to effectively reduce pain and anxiety for a wide range of pediatric ages.

Survival analysis and mortality predictors of hospitalized severe burn victims in a Malaysian burns intensive care unit

Background

Prognostic measures to determine burn mortality are essential in evaluating the severity of individual burn victims. This is an important process of triaging patients with high risk of mortality that may be nursed in the acute care setting. Malaysian burn research is lacking with only one publication identified which describes the epidemiology of burn victims. Therefore, the objective of this study was to go one step further and identify the predictors of burn mortality from a Malaysian burns intensive care unit (BICU) which may be used to triage patients at higher risk of death.

Methods

This is a retrospective cohort study of all admissions to Hospital Sultan Ismail’s BICU from January 2010 till October 2015. Admission criteria were in accordance with the American Burn Association guidelines, and risk factors of interest were recorded. Data was analyzed using simple logistic regression to determine significant predictors of mortality. Survival analysis with time to death event was performed using the Kaplan-Meier survival curve with log-rank test.

Results

Through the 6-year period, 393 patients were admitted with a male preponderance of 73.8%. The mean age and length of stay were 35.6 (±15.72) years and 15.3 (±18.91) days. There were 48 mortalities with an overall mortality rate of 12.2%. Significant risk factors identified on simple logistic regression were total body surface area (TBSA) > 20% (p < 0.001), inhalation injury (p < 0.001) and presence of early systemic inflammatory response syndrome (SIRS) (p < 0.001). Survival analysis using Kaplan-Meier survival curve showed similar results with TBSA > 20%, presence of SIRS, mechanical ventilation and inhalation injury which were associated with poorer survival (p < 0.001).

Conclusion

The predictors of mortality identified in a Malaysian BICU were TBSA > 20%, early SIRS, mechanical ventilation and inhalation injury which were associated with poorer survival outcome. The immunological response differs from individual patients and influenced by the severity of burn injury. Early SIRS on admission is an important predictor of death and may represent the severity of burn injury. Patients who required mechanical ventilation were associated with mortality and it is likely related to the severity of pulmonary insults sustained by individual patients. This data is important for outcome prognostication and mortality risk counselling in severely burned patients.

Long-term mental health outcomes after unintentional burns sustained during childhood: a retrospective cohort study

Background

Burns are a devastating injury that can cause physical and psychological issues. Limited data exist on long-term mental health (MH) after unintentional burns sustained during childhood. This study assessed long-term MH admissions after paediatric burns.

Methods

This retrospective cohort study included all children (< 18 years) hospitalised for a first burn (n = 11,967) in Western Australia, 1980-2012, and a frequency matched uninjured comparison cohort (n = 46,548). Linked hospital, MH and death data were examined. Multivariable negative binomial regression modelling was used to generate incidence rate ratios (IRR) and 95% confidence intervals (CI).

Results

The burn cohort had a significantly higher adjusted rate of post-burn MH admissions compared to the uninjured cohort (IRR, 95% CI: 2.55, 2.07-3.15). Post-burn MH admission rates were twice as high for those younger than 5 years at index burn (IRR, 95% CI 2.06, 1.54-2.74), three times higher for those 5-9 years and 15-18 years (IRR, 95% CI: 3.21, 1.92-5.37 and 3.37, 2.13-5.33, respectively) and almost five times higher for those aged 10-14 (IRR, 95% CI: 4.90, 3.10-7.76), when compared with respective ages of uninjured children. The burn cohort had higher admission rates for mood and anxiety disorders (IRR, 95% CI: 2.79, 2.20-3.53), psychotic disorders (IRR, 95% CI: 2.82, 1.97-4.03) and mental and behavioural conditions relating to drug and alcohol abuse (IRR, 95% CI: 4.25, 3.39-5.32).

Conclusions

Ongoing MH support is indicated for paediatric burn patients for a prolonged period after discharge to potentially prevent psychiatric morbidity and associated academic, social and psychological issues.
