Individual recovery of health-related quality of life during 18 months post-burn using a retrospective pre-burn measurement: an exploratory study.

PURPOSE: This study explored the individual trajectories of health-related quality of life (HRQL) compared to recalled pre-burn level of HRQL and investigated whether burn severity and post-traumatic stress disorder (PTSD) symptoms increase the risk of not returning to pre-burn level of HRQL. METHODS: Data were obtained from 309 adult patients with burns in a multicenter study. Patients completed the EQ-5D-3L questionnaire with a Cognition bolt-on shortly after hospital admission, which included a recalled pre-injury measure, and, again, at 3, 6, 12 and 18 months post-burn. Burn severity was indicated by the number of surgeries, and PTSD symptoms were assessed with the IES-R at three months post-burn. Pre- and post-injury HRQL were compared to norm populations. RESULTS: Recalled pre-injury HRQL was higher than population norms and HRQL at 18 months post-burn was comparable to population norms. Compared to the pre-injury level of functioning, four HRQL patterns of change over time were established: Stable, Recovery, Deterioration, and Growth. In each HRQL domain, a subset of patients did not return to their recalled pre-injury levels, especially with regard to Pain, Anxiety/Depression, and Cognition. Patients with more severe burns or PTSD symptoms were less likely to return to pre-injury level of functioning within 18 months post-burn. CONCLUSION: This study identified four patterns of individual change. Patients with more severe injuries and PTSD symptoms were more at risk of not returning to their recalled pre-injury HRQL. This study supports the face validity of using a recalled pre-burn HRQL score as a reference point to monitor HRQL after 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.

Laser speckle contrast imaging, an alternative to laser doppler imaging in clinical practice of burn wound care derivation of a color code.

OBJECTIVE: To develop a color code and to investigate the validity of Laser Speckle Contrast Imaging (LSCI) for measuring burn wound healing potential (HP) in burn patients as compared to the reference standard Laser Doppler Imaging (LDI). METHOD: A prospective, observational, cohort study was conducted in adult patients with acute burn wounds. The relationship between mean flux measured with LDI and mean perfusion units (PU) measured with LSCI was expressed in a regression formula. Measurements were performed between 2 and 5 days after the burn wound. The creation of a LSCI color code was done by mapping the clinically validated color code of the LDI to the corresponding values on the LSCI scale. To assess validity of the LSCI, the ability of the LSCI to discriminate between HP < 14 and ≥ 14 days and HP < 21 and original ≥ 21 days according to the LDI reference standard was evaluated, with calculation of receiver operating characteristics (ROC) curves. RESULTS: A total of 50 patients were included with a median age of 40 years and total body surface area burned of 6%. LSCI values of 143 PU and 113 PU were derived as the cut-off values for the need of conservative treatment (HP < 14 and ≥ 14 days) resp. surgical closure (HP < 21 and ≥ 21 days). These LSCI cut off values showed a good discrimination between HP 14 days versus ≥ 14 days (Area Under Curve (AUC)= 0.89; sensitivity 85% and specificity = 82%) and a good discrimination between HP 21 days versus ≥ 21 days (AUC of 0.89, sensitivity 81% and specificity 88%). CONCLUSION: This is the first study in which a color code for the LSCI in adult clinical burn patients has been developed. Our study reconfirms the good performance of the LSCI for prediction of burn wound healing potential. This provides additional evidence for the potential value of the LSCI in specialized burn care.

Pain and Posttraumatic Stress Symptom Clusters: A Cross-Lagged Study.

Pain and posttraumatic stress disorder (PTSD) frequently co-occur but underlying mechanisms are not clear. This study aimed to test the development and maintenance of pain and PTSD symptom clusters, i.e., intrusions, avoidance, and hyperarousal. The longitudinal study included 216 adults with burns. PTSD symptom clusters, indexed by the Impact of Event Scale-Revised (IES-R), and pain, using a graphic numerical rating scale (GNRS), were measured during hospitalization, 3 and 6 months post-burn. Cross-lagged panel analysis was used to test the relationships between pain and PTSD symptom clusters. Cross-lagged results showed that in-hospital intrusions predicted pain and avoidance 3 months post-burn. In-hospital pain predicted intrusions and avoidance 3 months post-burn and a trend was found for hyperarousal (90% CI). In the second wave, intrusions predicted pain and hyperarousal. Pain predicted hyperarousal. This study provides support for an entangled relationship between pain and PTSD symptoms, and particularly subscribes the role of intrusions in this bidirectional relationship. To a lesser extent, hyperarousal was unidirectionally related to pain. These results may subscribe the driving role of PTSD, particularly intrusions, which partly supports the Perpetual Avoidance Model.

Parents' memories and appraisals after paediatric burn injury: a qualitative study.

Background: It is well established that a paediatric burn injury can lead to parental post-traumatic stress symptoms. The content of parents' memories and appraisals may reveal the traumatic experiences that need attention. Objective: To inform clinical practice, the aim of this study was to qualitatively examine parents' (intrusive) memories and appraisals, and associated emotions, concerning the injury, the hospitalisation, and its consequences. Method: Approximately three to six months after the burn event, semi-structured interviews were conducted with parents of 18 children (0-16 years old) that had been hospitalised for a burn injury. Thematic analysis was carried out to obtain themes. Results: A central element in parents' memories and appraisals was a sense of external or internal threat. Intrusive memories were predominantly related to the accident and first aid (i.e. threat of the injury), whereas parents' memories about the child's suffering were emotional but not experienced as intrusive. Later appraisals of the burn injury and its consequences included negative appraisals of the child's increased vulnerability, responsibility of self or other, the child's prolonged suffering and (risk of) permanent change, as well as appraisals of positive outcome and recovery. Emotions commonly reported in the context of memories and appraisals were fear, sadness, guilt, and relief. Conclusions: This study offers insight into the traumatic nature of paediatric burn injury from the parent's perspective and provides directions for the delivery of trauma-informed (after)care.

Antecedentes: está bien establecido que una lesión por quemadura pediátrica puede provocar síntomas de estrés postraumático en los padres. El contenido de los recuerdos y de su evaluación por parte de los padres, puede revelar las experiencias traumáticas que necesitan atención.Objetivo: Informar la práctica clínica, el objetivo de este estudio fue examinar cualitativamente los recuerdos (intrusivos) de los padres y sus evaluaciones, y las emociones asociadas, en relación con la lesión, la hospitalización y sus consecuencias.Método: Aproximadamente de tres a seis meses después del evento de quemadura, se realizaron entrevistas semiestructuradas con padres de 18 niños (de 0 a 16 años de edad) que habían sido hospitalizados por una lesión por quemadura. Se realizó un análisis temático para obtener los temas.Resultados: Un elemento central en los recuerdos y evaluaciones de los padres era una sensación de amenaza externa o interna. Los recuerdos intrusivos se relacionaban predominantemente con el accidente y los primeros auxilios (i.e. la amenaza de lesión), mientras que los recuerdos de los padres sobre el sufrimiento del niño eran emocionales, pero no experimentado como intrusivo. Las evaluaciones posteriores de la lesión por quemaduras y sus consecuencias incluyeron evaluaciones negativas del aumento en la vulnerabilidad del niño, responsabilidad de sí mismo o de otro, el sufrimiento prolongado del niño y (el riesgo de) cambio permanente, así como una evaluación de resultados positivos y recuperación. Las emociones comúnmente reportadas en el contexto de los recuerdos y las valoraciones fueron el miedo, la tristeza, la culpa y el alivio.Conclusiones: este estudio ofrece información sobre la naturaleza traumática de la lesión por quemadura pediátrica desde la perspectiva de los padres y brinda instrucciones para brindar atención (posterior) a los traumas.

Parental presence or absence during paediatric burn wound care procedures.

AIM: Differing views on benefits and disadvantages of parental presence during their child's wound care after burn injury leave the topic surrounded by controversies. This study aimed to describe and explain parents' experiences of their presence or absence during wound care. METHODS: Shortly after the burn event, 22 semi-structured interviews were conducted with parents of children (0-16 years old) that underwent hospitalization in one of the three Dutch burn centers. Eighteen of these parents also participated in follow-up interviews three to six months after discharge. Interviews were analyzed using grounded theory methodology. RESULTS: Analyses resulted in themes that were integrated into a model, summarizing key aspects of parental presence during wound care. These aspects include parental cognitions and emotions (e.g., shared distress during wound care), parental abilities and needs (e.g., controlling own emotions, being responsive, and gaining overall control) and the role of burn care professionals. CONCLUSION: Findings emphasize the distressing nature of wound care procedures. Despite the distress, parents expressed their preference to be present. The abilities to control their own emotions and to be responsive to the child's needs were considered beneficial for both the child and the parent. Importantly, being present increased a sense of control in parents that helped them to cope with the situation. For parents not present, the professional was the intermediary to provide information about the healing process that helped parents to deal with the situation. In sum, the proposed model provides avenues for professionals to assess parents' abilities and needs on a daily basis and to adequately support the child and parent during wound care.

Prevalence of diabetic retinopathy, cataract and visual impairment in patients with diabetes in sub-Saharan Africa.

BACKGROUND/AIMS: There are few published data on the prevalence of diabetic retinopathy in sub-Saharan Africa. We report the prevalence of all grades of retinopathy and associations with systemic parameters in patients attending a secondary care diabetes clinic in Blantyre, Malawi. METHODS: Cross-sectional study of all patients attending for diabetes care in a hospital setting. Clinical examination and biochemical testing was performed to assess visual acuity (VA), grade of retinopathy (slit lamp biomicroscopy), microvascular complications, glycaemic control, hypertension and HIV status. Sight-threatening diabetic retinopathy (STDR) was defined as moderate preproliferative retinopathy or worse, circinate maculopathy or exudates within one disc diameter of the foveal centre or clinically significant macular oedema. RESULTS: In patients with type 2 diabetes (n=249) the prevalence (95% CI) of any retinopathy, STDR and proliferative diabetic retinopathy (PDR) was 32.5% (26.7 to 38.3%), 19.7% (14.7 to 24.6%) and 4.8% (2.2 to 7.5%), respectively. The presence of STDR was associated with albuminuria (OR 2.6; p=0.02), the presence of neuropathy (OR 3.4; p=0.005) and insulin use (OR 5.3; p=0.0004), but not with HIV status. In patients with type 1 diabetes (n= 32), the prevalence of any retinopathy, STDR and PDR was 28.1% (12.5 to 43.7%), 18.8% (5.2 to 32.2%) and 12.5% (1.0 to 24.0%), respectively. 12.1% of study subjects had VA worse than 6/18 (20/60). CONCLUSION: This study provides baseline information on prevalence of all grades of retinopathy and STDR in consecutive cases attending an urban/semi-urban diabetes clinic in sub-Saharan Africa. Prevalence of STDR was high and in type 2 diabetes was associated with albuminuria, neuropathy and insulin use.

A survey of the management, control, and complications of diabetes mellitus in patients attending a diabetes clinic in Blantyre, Malawi, an area of high HIV prevalence.

The aim of this study was to describe the current status of diabetes care in an urban diabetes clinic in Malawi and the prevalence of human immunodeficiency virus (HIV) in this population, investigating possible associations between HIV and diabetes. A systematic prospective survey of patients attending the diabetes clinic at a teaching hospital in Blantyre, Malawi was conducted. Six hundred twenty patients were assessed. Seventy-four percent had glycosylated hemoglobin (HbA1C) > 7.5%. Systolic blood pressure was > 140 mm Hg in 52% of patients. Hypertension was more common in patients with raised creatinine (P < 0.003), retinopathy (P = 0.01), and stroke (P < 0.0002). Microvascular complication rates were high, specifically nephropathy (34.7%), retinopathy (34.7%), and neuropathy (46.4%). HIV seroprevalence was 13.7%. HIV-positive subjects had a lower body mass index (BMI) and lower fasting blood sugar, and they were more likely to have albuminuria (48.0% versus 33.3%; P < 0.05). Control of glycemia and hypertension were poor, and microvascular complications were common. Nephropathy in diabetic patients may be affected by HIV status.
