Psychopathology and psychological problems in patients with burn scars: epidemiology and management.

Burn injury is often a devastating event with long-term physical and psychosocial effects. Burn scars after deep dermal injury are cosmetically disfiguring and force the scarred person to deal with an alteration in body appearance. In addition, the traumatic nature of the burn accident and the painful treatment may induce psychopathological responses.Depression and post-traumatic stress disorder (PTSD), which are prevalent in 13–23% and 13–45% of cases, respectively, have been the most common areas of research in burn patients. Risk factors related to depression are pre-burn depression and female gender in combination with facial disfigurement. Risk factors related to PTSD are pre-burn depression, type and severity of baseline symptoms, anxiety related to pain, and visibility of burn injury. Neuropsychological problems are also described, mostly associated with electrical injuries. Social problems include difficulties in sexual life and social interactions. Quality of life initially seems to be lower in burn patients compared with the general population. Problems in the mental area are more troublesome than physical problems. Over a period of many years, quality of life was reported to be rather good. Mediating variables such as low social support, emotion and avoidant coping styles, and personality traits such as neuroticism and low extraversion, negatively affect adjustment after burn injury.Few studies of psychological treatments in burn patients are available. From general trauma literature, it is concluded that cognitive (behavioral) and pharmacological (selective serotonin reuptake inhibitors) interventions have a positive effect on depression. With respect to PTSD, exposure therapy and eye movement reprocessing and desensitization are successful. Psychological debriefing aiming to prevent chronic post-trauma reactions has not, thus far, shown a positive effect in burn patients. Treatment of problems in the social area includes cognitive-behavioral therapy, social skills training, and community interventions. Sexual health promotion and counseling may decrease problems in sexual life.In conclusion, psychopathology and psychological problems are identified in a significant minority of burn patients. Symptoms of mood and anxiety disorders (of which PTSD is one) should be the subject of screening in the post-burn phase and treated if indicated. A profile of the patient at risk, based on pre-injury factors such as pre-morbid psychiatric disorder and personality characteristics, peri-traumatic factors and post-burn factors, is presented. Finally, objective characteristics of disfigurement appear to play a minor role, although other factors, such as proneness to shame, body image problems, and lack of self-esteem, may be of significance.

Psychological consequences of pediatric burns from a child and family perspective: a review of the empirical literature.

In order to inform clinical practice, we reviewed the empirical literature on emotional, behavioral and social outcomes in children with burns and their families published between 1989 and 2011. A systematic search of the literature yielded 75 articles. Qualitative synthesis of the results showed that child anxiety, traumatic stress reactions, and behavioral problems were considerably prevalent in the first months after the burn event. Among parents, high rates of posttraumatic stress, depressive symptoms, and guilt feelings were found. Cross-sectional studies, often performed many years after the injury, suggest that some children experience long-term psychological problems, such as anxiety, depression, and difficulties with social functioning. However, there was little evidence that behavior in general, self-esteem, or body image were impaired in the total population of children with a history of burns. Long-term family outcome studies suggest that psychological problems persist in a substantial subgroup of parents. Child peritraumatic factors anxiety and pain, parental posttrauma psychological reactions, and family functioning were the most consistently reported factors associated with child outcome. More recent studies have demonstrated that burn severity may have an indirect effect on child postburn psychosocial outcome. Clinical implications, methodological strengths and limitations of the reviewed studies, and directions for future research are discussed.

Health-related quality of life after burns : a prospective multicentre cohort study with 18 months follow-up.

Background: Health-related quality of life (HRQOL) is an important parameter after medical treatments. Knowledge of (predictors of) diminished quality of life can help improve medical outcome. The aim of this study was to quantify health loss in patients with burns and to assess the contribution of injury extent, age, gender, and psychologic factors to HRQOL and speed of recovery. A multicenter prospective cohort design was used to address these aims. Methods: Data were obtained from 260 adults with burns. Patients completed the EQ-5D at 3 weeks, 3, 6, 9, and 18 months after burn and psychologic questionnaires during hospitalization. Patients scores were compared with an age- and gender-weighted norm population. Results: Patients suffered from substantial health losses at short term, but after 18 months the majority reached a HRQOL comparable with the norm population with the exception of patients requiring two or more surgeries. The best predictor of long-term HRQOL and the speed of recovery was the number of surgeries, followed by psychologic problems. Both predicted baseline and trajectories of improvement. Symptoms of traumatic stress were most debilitating over time. Conclusions: Both injury severity and psychologic problems play a pivotal role in reduced HRQOL and the speed of recovery. The number of surgeries seems to give a practically useful indication of the expected recovery speed that could aid in decision making and provides adequate information for patients in the aftermath of their initial surgical treatment. Screening for traumatic stress is recommended.

Analyzing small data sets using Bayesian estimation: the case of posttraumatic stress symptoms following mechanical ventilation in burn survivors

Background The analysis of small data sets in longitudinal studies can lead to power issues and often suffers from biased parameter values. These issues can be solved by using Bayesian estimation in conjunction with informative prior distributions. By means of a simulation study and an empirical example concerning posttraumatic stress symptoms (PTSS) following mechanical ventilation in burn survivors, we demonstrate the advantages and potential pitfalls of using Bayesian estimation. Methods First, we show how to specify prior distributions and by means of a sensitivity analysis we demonstrate how to check the exact influence of the prior (mis-) specification. Thereafter, we show by means of a simulation the situations in which the Bayesian approach outperforms the default, maximum likelihood and approach. Finally, we re-analyze empirical data on burn survivors which provided preliminary evidence of an aversive influence of a period of mechanical ventilation on the course of PTSS following burns. Results Not suprisingly, maximum likelihood estimation showed insufficient coverage as well as power with very small samples. Only when Bayesian analysis, in conjunction with informative priors, was used power increased to acceptable levels. As expected, we showed that the smaller the sample size the more the results rely on the prior specification. Conclusion We show that two issues often encountered during analysis of small samples, power and biased parameters, can be solved by including prior information into Bayesian analysis. We argue that the use of informative priors should always be reported together with a sensitivity analysis.

Prevalence and co-morbidity of psychiatric disorders 1–4 years after burn

OBJECTIVE Currently, little is known about psychiatric disorders in the period following on the first year after burn. We examined the prevalence of DSM-IV Axis I disorders in burn patients 1-4 years after burn, using a standardized structured clinical interview and comparing findings with a representative general population sample. METHODS Ninety patients admitted to five burn centres were assessed with the 12-month Composite International Diagnostic Interview. Results were compared to an age and gender matched nation based norm group. RESULTS Twelve-month prevalence for any DSM-IV study disorder was 39%. Prevalence for any after burn onset disorder was 28%. Most prevailing were major depression (10%), generalized anxiety disorder (10%), and PTSD (7%). The comorbidity-proportions for PTSD and generalized anxiety disorder where the highest. Fifty-seven percent of all burn onset disorders started within 1 year after the trauma and 21% within the next year. Burn patients had significantly higher prevalence rates for DSM-IV disorders than people from the general population sample. CONCLUSION Psychiatric morbidity among burn patients, 1-4 years after burn, is considerable and higher than what may be expected in the general population. A 2-year follow-up for anxiety and depression disorder is warranted.

Reliability, validity and clinical utility of three types of pain behavioural observation scales for young children with burns aged 0-5 years

&NA; Pain measurement is a prerequisite for individualized pain management and research into pain interventions. There is a need for reliable and valid pain measures for young children with burns. The aim of this study was to investigate whether the pain observation scale for young children (POCIS), the COMFORT behaviour scale (COMFORT‐B) and the nurse observational visual analogue scale (VAS obs) are reliable, valid and clinically useful instruments to measure pain in children with burns aged 0–5 years. Participating trained nurses (N = 102) rated pain of 154 children during hospitalization. Two trained nurses simultaneously assessed pain at fixed intervals by using the previous mentioned measures. Cronbachs alpha for POCIS was .87 for background and .89 for procedural pain. Intraclass Correlation Coefficients (ICCs) were .75 for background and .81 for procedural pain. COMFORT‐B observations yielded Cronbachs alpha of .77 for background and .86 for procedural pain and ICCs of .83 for background and .82 for procedural pain. The VAS obs resulted in ICCs of .55 for background and .60 for procedural pain. Correlation coefficient between POCIS and COMFORT‐B was .79 (p < .01), Standardized response mean was 1.04 for both POCIS and COMFORT‐B. Background pain measured with POCIS and COMFORT‐B was lower than procedural pain (p < .001). Nurses found POCIS easier and quicker to use, but COMFORT‐B was found to indicate pain more accurately. Both POCIS and COMFORT‐B are reliable, valid and practical scales for pain measurement in young children with burns and can be used in practice and research. The VAS obs was found to be unreliable.

Brief Report: Mothers’ Long-term Posttraumatic Stress Symptoms Following a Burn Event of Their Child

OBJECTIVE This prospective longitudinal study examines the course of posttraumatic stress symptoms (PTSS) in mothers of children with burns between 1 and 11 years after the burn event and the role of burn severity and feelings of guilt on this course. METHOD Self-reported PTSS of 48 mothers were measured with the Impact of Event Scale. Guilt feelings were assessed during an in-depth interview 2 years after the burn event. Eleven years after the burn event, mothers marked their childs scars at the present time on a drawing. RESULTS Over a period of 10 years, maternal PTSS decreased. Multiple regression analysis showed that the interaction between guilt and burn severity predicted the course of PTSS. CONCLUSIONS Although PTSS substantially decreases through the years, a subset of mothers, in particular mothers who feel guilty about the burn event and whose children have more extensive permanent scarring seem at risk for longer term PTSS.

Reliability and Validity of the Dutch Version of the American Burn Association/Shriners Hospital for Children Burn Outcomes Questionnaire (5–18 Years of Age)

The American Burn Association/Shriners Hospital for Children Burn Outcomes Questionnaire (BOQ) is a self-administered questionnaire to monitor functional outcome after burns in children and adolescents. This study aimed to assess feasibility, reliability, and validity of the Dutch BOQ. The BOQ was adapted into Dutch and tested in a population of children and adolescents aged 5 to 15 years who were primary admissions to a Dutch or Belgian burn center (n = 6) during the period of March 2001 through February 2004. To assess validity, the Child Health Questionnaire (CHQ) and the EuroQol-5D (EQ-5D) were included. Response rate was 53% among parents (n = 145) and 48% among adolescents (n = 52). Internal consistency of the BOQ scales was good (Cronbach’s &agr; >0.7 in all but one scale). Test and retest results were similar; there were no significant differences between parents and adolescents in this respect. Expected high correlations between BOQ scales and conceptually equivalent CHQ and EQ-5D scales were found in eight of 12 comparisons. Eleven scales showed significant differences in the expected direction between children with a long length of stay versus those with a short length of stay. The Dutch BOQ can be used to evaluate functional outcome after burns in children aged 5 years and older. Our study showed that the Dutch BOQ is a feasible instrument with good reliability and validity.

Impact of facial burns: relationship between depressive symptoms, self-esteem and scar severity ☆ ☆☆

OBJECTIVE This study assessed the role of self-reported facial scar severity as a possible influencing factor on self-esteem and depressive symptoms in patients with facial burns. METHOD A prospective multicentre cohort study with a 6 months follow-up was conducted including 132 patients with facial burns. Patients completed the Patient and Observer Scar Assessment Scale, the Rosenberg Self-esteem Scale and the Hospital Anxiety and Depression Scale. Structural Equation Modeling was used to assess the relations between depressive symptoms, self-esteem and scar severity. RESULTS The model showed that patient-rated facial scar severity was not predictive for self-esteem and depressive symptoms six months post-burn. There was, however, a significant relationship between early depressive symptoms and both patient-rated facial scar severity and subsequent self-esteem. The variables in the model accounted for 37% of the variance in depressive symptoms six months post-burn and the model provided a moderately well-fitting representation of the data. CONCLUSION The study suggests that self-esteem and depressive symptoms were not affected by self-reported facial scar severity but that earlier depressive symptoms were indicative for a more severe self-reported facial scar rating. Therefore, routine psychological screening during hospitalisation is recommended in order to identify patients at risk and to optimise their treatment.

Posttraumatic Stress Symptoms after Exposure to Two Fire Disasters: Comparative Study

This study investigated traumatic stress symptoms in severely burned survivors of two fire disasters and two comparison groups of patients with “non-disaster” burn injuries, as well as risk factors associated with acute and chronic stress symptoms. Patients were admitted to one out of eight burn centers in the Netherlands or Belgium. The Impact of Event Scale (IES) was administered to 61 and 33 survivors respectively of two fire disasters and 54 and 57 patients with “non-disaster” burn etiologies at 2 weeks, 3, 6, 12 and 24 months after the event. We used latent growth modeling (LGM) analyses to investigate the stress trajectories and predictors in the two disaster and two comparison groups. The results showed that initial traumatic stress reactions in disaster survivors with severe burns are more intense and prolonged during several months relative to survivors of “non-disaster” burn injuries. Excluding the industrial fire group, all participants’ symptoms on average decreased over the two year period. Burn severity, peritraumatic anxiety and dissociation predicted the long-term negative outcomes only in the industrial fire group. In conclusion, fire disaster survivors appear to experience higher levels of traumatic stress symptoms on the short term, but the long-term outcome appears dependent on factors different from the first response. Likely, the younger age, and several beneficial post-disaster factors such as psychosocial aftercare and social support, along with swift judicial procedures, contributed to the positive outcome in one disaster cohort.
