Cost-effectiveness of laser Doppler imaging in burn care in the Netherlands

Background: Early accurate assessment of burn depth is important to determine the optimal treatment of burns. The method most used to determine burn depth is clinical assessment, which is the least expensive, but not the most accurate.Laser Doppler imaging (LDI) is a technique with which a more accurate (>95%) estimate of burn depth can be made by measuring the dermal perfusion. The actual effect on therapeutic decisions, cli

A noncommutative generalization of Auslander's last theorem

We show that every finitely generated left R-module in the Auslander class over an n-perfect ring R having a dualizing module and admitting a Matlis dualizing module has a Gorenstein projective cover

Psychometric Performance of the Stony Brook Scar Evaluation Scale and SCAR-Q Questionnaire in Dutch Children after Pediatric Surgery

Introduction: The growing population of survivors following pediatric surgery emphasizes the importance of long-term follow-up. The impact of surgical scars on daily life can be evaluated through patient-reported outcome measurements. The Stony Brook Scar Evaluation Scale (SBSES) and SCAR-Q questionnaire are two interesting instruments for this purpose. We evaluated their psychometric performance in Dutch children after pediatric surgery. Methods: After English–Dutch translation, we evaluated—following the COSMIN guidelines—the feasibility, reliability (internal and external), and validity (construct, criterion, and convergent) of the SBSES and SCAR-Q in Dutch patients &lt; 18 years old with surgical scars. Results: Three independent observers completed the SB for 100 children (58% boys, median age 7.3 (IQR 2.5–12.1) years) in whom surgery had been performed a median of 2.8 (0.5–7.9) years ago. Forty-six of these children (61% boys, median age 12.1 (9.3–16.2) years) completed the SCAR-Q. Feasibility and internal reliability (Cronbach’s alpha &gt; 0.7) was good for both instruments. For the SB, external reliability was poor to moderate (interobserver variability: ICC 0.46–0.56; intraobserver variability: ICC 0.74). For the SCAR-Q, external reliability was good (test–retest agreement: ICC 0.79–0.93). Validity tests (construct, criterion, and convergent) showed poor to moderate results for both instruments. Conclusions: The Dutch-translated SBSES and SCAR-Q showed good feasibility and internal reliability. External reliability and validity were likely affected by differences in conceptual content between the questionnaires. Combining them would provide insight in the impact of scars on patients. Implementation of these instruments in longitudinal follow-up programs could provide new insights into the long-term psychological outcome after pediatric surgery.</p

Burns to the head and neck:epidemiology and predictors of surgery

BACKGROUND: The face is a frequent site of burn, but prevalence rates vary and reports are often limited to one healthcare setting. We examined the incidence of facial burns in the Netherlands in Emergency Departments (ED), hospitals and burn centres. Additionally, we identified which patient, injury and burn-related characteristics were predictors of facial burns, facial surgery and facial reconstruction in burn centres. METHODS: A retrospective, observational study was conducted including data from the Dutch Injury Surveillance System, the National Hospital Discharge Register and burn centres in a 5-year period (2003-2007). RESULTS: Facial burn incidences per 100,000 were 15.1 for ED visits, 1.3 for hospital admissions and 1.4 for burn centre admissions. A total of 2691 patients were admitted to Dutch burn centres; 47.5% (n=1277) had facial burns of which 20.5% received primary facial surgery and 5.3% received facial reconstruction in follow-up. Predictors of facial burns and facial surgery were identified. Predictors of facial reconstructive surgery were burns to the neck (ventral), fire/flame burns and number of facial surgeries in the acute phase of the burn. CONCLUSIONS: One in five patients with facial burns admitted to a Dutch burn centre received primary facial surgery and 1 in 20 received facial reconstructive surgery within a follow-up of minimum 2 years
