Italian Society of Cardiovascular Echography (SIEC) Consensus Conference on the state of the art of contrast echocardiography.

Part 1: Technical and methodological issues. Contrast echocardiography is based on the use of gas microbubbles. The size, gas composition and shell structure of the microbubbles modify their stability, resistance to pressure and scattering behavior. A proposed classification of contrast agents is based on the modalities of production of microbubbles (galenic or industrial); the industrial agents are divided into three generations depending on their characteristics. Following venous administration, the industrial microbubbles behave as intravascular free-flowing tracers and this is fundamental for their use in perfusion studies. When insonated at a low acoustic pressure, microbubbles show a linear behavior and can be used for signal amplification. At intermediate acoustic pressures microbubbles resonate and produce a harmonic signal that is detectable by new scanners. Higher acoustic pressures cause microbubble disruption with emission of a transient acoustic signal. The available contrast agents behave differently in an ultrasound field. Part 2: Safety of contrast echocardiography. Galenic contrast agents were tested in many studies for intracoronary and intravenous injection and no clinically relevant side effects were detected. The intravenous injection of industrial contrast agents is safe in all conditions, even in acute coronary syndromes. The interaction between ultrasound and microbubbles produces energy with potential effects on tissue for inertial cavitation and acoustic current production. These effects seem particularly interesting for the therapeutic applications of contrast echocardiography, but they do not appear to have clinically relevant effects. Part 3: Experimental studies. Experimental studies in contrast echocardiography are designed to induce, in animal models, acute myocardial infarction and coronary artery stenosis and to evaluate the differences in blood flow. The risk area and infarct area are well visualized with serial contrast agent infusion. No-reflow after coronary occlusion is a well-known phenomenon and is detectable at contrast echocardiography. Different degrees of induced coronary stenosis cause differences in the regional flow rate. The results of contrast echocardiographic studies are comparable with those of other invasive flow measurements. Caution must be used to transfer the knowledge acquired from animal studies to the clinical arena, owing to both methodological and anatomical differences. Part 4: Enhancement of Doppler signal and coronary flow study. The anterior descending coronary artery flow is detectable in almost all patients, and the posterior descending coronary artery in about 70%. The coronary flow reserve can be measured by injection of a vasodilator agent (dipyridamole or preferably adenosine) with a success rate of almost 100 % for the anterior descending but only 50 % for the posterior descending coronary artery. Data from transthoracic studies are comparable with those of Doppler flow wire. The fields of application presently include the evaluation of acute myocardial infarction, the short- and long-term results of percutaneous coronary interventions and coronary grafts, and the study of the microcirculation in several clinical conditions where the coronary flow reserve may be reduced, such as in syndrome X, hypertension, hypercholesterolemia or diabetes. Part 5: Endocardial border enhancement. Opacification of the left ventricle is the main indication to contrast echocardiography that, in this setting, is principally used to improve endocardial border delineation. This allows accurate evaluation of left ventricular volumes and function, increasing the role of echocardiography for the quantitative study of the left ventricle. Other indications for left ventricular opacification are the identification of intraventricular thrombosis, non-compaction of the left ventricle and heart rupture. In this respect, industrial second-generation contrast agents are more useful. The most appropriate patients for contrast echocardiography are those with a poor or suboptimal acoustic window, in whom a predictable diagnostic and prognostic usefulness of the procedure is expected. If appropriately used, contrast echocardiography is a cost-effective technique, although lack of reimbursement presently limits its use. Part 6: Use of contrast agents during stress echocardiography. Contrast agents during stress echocardiography may be used to improve the diagnostic accuracy of the test and to study myocardial perfusion. The diagnosis of ischemia in stress echo relies on the operator's visual assessment of changes in contractility during stress. Contrast agents must be considered an important tool that improve image quality especially in patients with an intermediate or poor acoustic window and their use has been reported to be cost-effective in the few studies designed to this end. The evaluation of myocardial perfusion during stress is certainly one of the most important goals of contrast echocardiography. Preliminary data are interesting but there is still a number of methodological problems that currently hamper clinical application. Part 7: Myocardial perfusion. Echocardiography has the potential of visualizing microbubbles in the microcirculation by detecting stimulated acoustic emission, produced by high-energy applied ultrasound, or by detecting the harmonic signal produced by resonance of the microbubbles in a low-energy ultrasound field. In the first case images are triggered at increasing end-systolic intervals (intermittent imaging), whereas in the second case entire cardiac cycles are analyzed (real-time imaging). Continuous infusion is the preferred method of maintaining a large and constant microbubble concentration inside the microcirculation. Analysis of the perfusion signal may be made in the qualitative, semi-quantitative or quantitative mode. Quantitative analysis is based on the construction of videointensity-time curves to study the refilling phase after complete microbubble destruction. There are not enough data in the literature showing the additional role of quantitative analysis for clinical purposes. Thus, at present, quantitative softwares should be considered as research tools. Conversely, there is a general consensus based on experimental and clinical studies on the use of myocardial contrast echo in patients with acute myocardial infarction by means of qualitative or semi-quantitative analysis. Important information on the infarct area extension, on the efficacy of reperfusion therapy, on the presence and extension of the no-reflow phenomenon and on the extent of residual tissue viability may be derived from the routine use of myocardial contrast echo. The reference technique still remains myocardial scintigraphy even though many theoretical problems are being discussed. Part 8: Implementing ultrasound contrast in the echocardiography laboratory. Contrast echocardiography should be considered an extension of the existing echocardiographic examination. Standard laboratory equipment is sufficient to run a contrast echocardiography program. However, cultural and technological upgrading is mandatory to obtain good results in contrast echocardiography. Intravenous infusion is easier during stress echocardiography than during rest study, because the time and cost for the venous line are comprised. In this setting, the cost-effectiveness for the addition of contrast agent is optimal, but patient selection is a critical point. The economic issue (contrast agent and personnel costs, and time needed) of contrast echocardiography determines the fact that without adequate reimbursement there is no incentive to perform the procedure.

[A screening tool to identify older people at risk of adverse health outcomes at the time of hospital admission].

The proportional increase of the ageing population results in an ever growing percentage of elderly among hospitalised patients. Older patients have complex medical, social and psychological problems that could benefit from coordinated care or case management. Identification of high-risk older adults is mandatory to initiate a liaison geriatric management program. A simple screening tool is presented to identify older people at the time of admission who are at increased risk of adverse health outcomes. The instrument was validated during a period of 6 months when all (n = 618) older adults (> 70 year) hospitalised in non-geriatric departments of a general hospital were screened. This "Variable Indicative of Placement risk" (VIP) shows a good sensitivity (81%) and specificity (86%) and has a high Negative Predictive Value (97%). Furthermore, it shows a significant positive correlation with the length of stay (p < 0.001). The questionnaire turned out to be a very useful tool in the emergency department as well as in other wards because it probes premorbid frailty components with three simple questions. Due to its simplicity a nurse without geriatric training can complete it. Patients who are not at risk of an adverse outcome are easily recognised. A positive score indicates loss of functional independence and a risk of increased length of stay. Further geriatric assessment and intervention seem then appropriate.

Family physicians in university hospital intensive care units.

Although physicians in most family practice residency programs hospitalize their patients at community hospitals, those in 21 programs in the United States hospitalize patients exclusively at university hospitals. Through a questionnaire mailed to directors of each of these programs, it was learned that family practice residency faculty have medical intensive care (ICU) privileges at 38 percent of these university hospitals. No family physicians had ever been denied ICU privileges at any of these hospitals. Mandatory consultations were reported by only a minority of programs. At 62 percent of these university hospitals, family physicians do not have ICU privileges. However, no family physician had every made a formal application for them. Intensive care patients at these hospitals were generally cared for by specialists and house staff in internal medicine or critical care.

Laparoscopic skills laboratories: current assessment and a call for resident training standards.

BACKGROUND: Numerous protocols for laparoscopic skills training using simulator-based laboratories have proven effective. However, little is known about the availability and uniformity of such facilities. The purpose of this study was to evaluate the prevalence, utilization, and costs of skills laboratories currently in use. METHODS: A survey was mailed to 253 general surgery program directors to determine the perceived value, prevalence, equipment, types of training, supervision, and costs of the labs. RESULTS: One hundred sixty-two (64%) programs completed the survey. Eighty-eight percent of responders consider skills labs effective in improving operating room performance; however, only 55% have skills labs. Of 89 programs with skills labs, 99% have videotrainer equipment (mean 3.8 trainers per lab, range 1 to 15); 46% have virtual reality trainer equipment (mean 1.7 trainers per lab, range 1 to 7). Eighty-two percent of programs teach basic skills using a variety of tasks (Rosser/Southwestern stations, MIST-VR, MISTELS, department-created); 96% teach suturing (intracorporeal, extracorporeal, suture devices). On average, residents train 0.8 hours per week (range 0 to 6). Training is mandatory in 55% and supervised in 73% of the programs. The mean development cost was 133,000 dollars (range 300 dollars to 1,000,000 dollars). CONCLUSIONS: While a large majority of program directors consider skills labs important, 45% of programs have no such facilities. Moreover, significant variability of equipment and training practices exist in currently available labs. Strategies are needed for more widespread implementation of skills labs, and standards should be developed to facilitate uniform adoption of validated curricula that reliably maximize training efficiency and educational benefit.

Preclinical pharmacokinetics: an approach towards safer and efficacious drugs.

Lack of efficacy and toxicity are considered to be major reasons for drug failures and pharmacokinetics governs them to a large extent. Compound with favorable pharmacokinetics is more likely to be efficacious and safe. Therefore, the preclinical pharmacokinetic evaluation should be comprehensive enough to ensure that compounds do not fail in the clinic. Preclinical ADME screening facilitates early elimination of weak candidates and directs the entire focus of the drug development program towards fewer potential lead candidates. Hence, it is mandatory that the pre-clinical candidates are subjected to as many possible reality checks. Reliance on in-vitro tests should be minimized because they do not represent the real physiological environment but rather slow down the pace of a drug discovery program. Compounds can be straight away subjected to in-vivo high throughput screens such as cassette dosing, cassette analysis or rapid rat screen etc. Candidates with the desired in-vivo pharmacokinetic profile may be further profiled in-vitro, using assays such as metabolic stability, reaction phenotyping, CYP-450 inhibition and induction, plasma protein binding etc. in human microsomes, human recombinant CYP-450 enzymes and human plasma. This also provides an early indication of whether the compound which worked in animals would work in human as well. In-vitro metabolic stability profile is a qualitative as well as quantitative comparison of metabolism of a compound in human and animal models. It helps in identifying the right model for toxicity studies. Extensive metabolism is generally considered a liability as it limits the systemic exposure and shortens the half-life of a compound. Several strategies such as reduction of lipophilicity, modification and / or blocking of metabolically soft spots and use of enzyme inhibitors; have been developed to combat metabolism. In spite of several concerns, the fact that active metabolites of several marketed drugs have been developed as drugs with better efficacy, safety and pharmacokinetics profile; cannot be denied. Therefore, instead of considering metabolic instability a liability it can be exploited as a tool for discovering better drugs. It is equally important to identify the metabolic pathways of the drug candidates by conducting in-vitro CYP450 reaction phenotyping assays. The identification of drug metabolizing enzymes involved in the major metabolic pathways of a compound helps in predicting the probable drug-drug interactions in human. Compounds with more than one metabolic pathway have less likelihood of clinically significant drug interactions. In-vitro CYP450 inhibition and induction screens are used to evaluate the potential of compound towards drug - drug interactions and the most prone candidates may either be discarded or taken ahead with a caution. It is known that only unbound drug is pharmacologically active and therefore the assessment of bound fraction by the estimation of plasma protein binding of a compound is another important parameter to be explored in-vitro. In addition to the process of 'weeding out' weak candidates early in the drug discovery process, it is equally important to identify the probable causes of poor ADME exhibited by some compounds as this information is useful to medicinal chemists for improving upon backbones that exhibit un favorable pharmacokinetic profile. Toxicity study is the foundation of an INDA (Investigational new drug application) and therefore, the final selection of a compound can be performed only after proper toxicological evaluation in animal models. Toxicokinetics forms an integral part of toxicity study and is used to assess the exposure of candidates in toxicity models and correlate the drug levels in blood and various tissues with the toxicological findings. Although in-vivo screening of compounds in animal models and in-vitro assays in human recombinant CYP-450 enzymes help in drug candidate selection, both approaches have their own limitations. There is no certainty that the selected candidates will exhibit the desired target PK profile in human and real human PK remains suspense until the compound enters Phase-1 clinical trial. The recognition of human micro dosing, (HMD) by medicines and healthcare products regulatory agency (MHRA) and European agency for evaluation of medicinal products [EMEA] is a stepping stone in the direction of obtaining human PK data early in the preclinical stage. This would gradually shift the focus of early drug development away from animal studies directly towards safe and ethical studies in human yielding more relevant and reliable pharmacokinetic data. HMD would provide an answer to the growing public demand for a reduction in the use of animals for pharmaceutical development.

[Autologous blood donation from the viewpoint of the anesthetist].

The anesthesiological aspect regarding autologous donation/autologous predeposition aims at the following criteria: (1) Which patient is eligible for autologous donation? (2) Which kind of monitoring should be established for the donation procedure? (3) What are the quality criteria the autologous predeposit has to meet? (4) What are the logistical aspects of an autologous predeposit program managed by an anesthesis? Under anesthesiological aspects all patients who have been declared eligible for elective surgery should be able to donate an autologous predeposit. Attention should be paid both to an adequate volume substitution, especially in patients with cardiovascular and/or coronary diseases, and to an adequate monitoring during autologous blood donation; e.g., a 3-lead ECG to monitor of cardiac rhythm and heart rate as well as close and discontinuous blood pressure control appear to be appropriate. There is no doubt that the quality criteria an autologous predeposit should meet are the same as those outlined for a homologous product; especially proof of no bacterial contamination is mandatory. Undoubtedly, an anesthesist managing an autologous predeposit program should have a broad experience in and a good knowledge of transfusion medicine.

Using self-studies to meet JCAHO requirements.

Using self-studies to provide mandatory information for hospital employees is both cost effective and time effective. Time invested in writing and distributing these programs is well worth it provided learning is verified through testing. Records of mandatory information can be kept either by hand on education cards or by computer. Periodic updates of material keep the self-study process fresh and interesting for participants and educators alike.

Fundamentals of ICANL accreditation.

The Intersocietal Commission for the Accreditation of Nuclear Medicine Laboratories (ICANL) has become a nationally recognized accreditation program with the primary goal of providing a multidisciplinary peer review program. The purpose of this paper is to review the structure and mission of the ICANL to help increase awareness of the importance of voluntary accreditation. Included is a broad review of the ICANL standards and their relationship to other nationally published standards and guidelines. A mandatory site visit is an integral part of the program, and specifics of the site visit are discussed along with a summary of the strengths and weaknesses of applicant laboratories. The benefits of voluntary accreditation will become clear as more facilities participate in the program.

Incorporating vaccine-preventable disease surveillance into the National Health Information Network: leveraging children's hospitals.

OBJECTIVE: Development of national biosurveillance systems to advance regional and national data exchange among sites of clinical care and public health authorities is a top federal priority, creating the opportunity to develop a unified national network for tracking and responding to cases of vaccine-preventable diseases. The purpose of this study was to assess the current practice and feasibility of developing a nationwide network of children's hospitals to conduct surveillance for vaccine preventable diseases. METHODS: In 2004-2005, Web-based surveys were sent to 506 key hospital personnel from 119 pediatric hospitals, identified by the National Association of Children's Hospitals and Related Institutions. Surveys measured attitudes toward public health initiatives, willingness to join a surveillance network of children's hospitals, knowledge of mandated reporting requirements, methods of disease detection and reporting, and data sources available for surveillance. RESULTS: A total of 395 (78%) respondents from 119 hospitals completed the survey. Surveillance at pediatric hospitals is largely passive and driven by unreimbursed efforts of infection control staff. It is vulnerable to missing cases that occur in the outpatient setting and are diagnosed clinically without laboratory confirmation or are never diagnosed by clinicians. Nearly 90% of hospital leaders are interested in participating in public health programs, and most are interested in a national network to conduct active surveillance for vaccine-preventable diseases, dependent on the provision of sufficient funding. Pediatric hospitals store records relevant to surveillance in an electronic fashion accessible to query, but <20% of these hospitals use automated methods to report cases of disease. CONCLUSIONS: There is both the will and capability to create a robust active pediatric hospital-based reporting system for vaccine preventable diseases. This effort would dovetail well with the national priority to bolster surveillance, as well as with the goal of reducing morbidity and mortality from vaccine-preventable diseases.

A system of analyzing medical errors to improve GME curricula and programs.

The report of the Institute of Medicine (IOM) To Err is Human recommended that both mandatory and voluntary event-reporting systems be established to identify and learn from errors. Because of the tight coupling of graduate medical education (GME) programs and the delivery of care, any event-reporting system used in a teaching hospital should be able to document the types of errors that are being made by graduate medical trainees (GTs). The authors performed an analysis of the root causes of events involving GTs that were recorded in hospital-based near-miss reporting systems. The root causes were classified using the Eindhoven Classification Model, medical version. Case histories of three separate events, one from an accident and emergency department in the United Kingdom, and two from a large teaching hospital in the United States, are used to illustrate the method. In all three cases, lack of knowledge on the part of the trainee contributed to the incident. Inadequate educational preparation had the potential for causing significant harm to the patient. Organizational causes were also present in each case, which illustrates the need to examine not only educational issues but also procedural and management issues related to GME. In each case, the analysis revealed in striking clarity deficiencies of educational content and problems of program structure. The authors conclude that doing a root-cause analysis in conjunction with a near-miss event-reporting system in a teaching hospital can be a valuable source of documented information to guide needed educational and system changes to GME programs.

Mandatory reporting of "imminent" death to identify organ donors: history, controversy, and potential solutions.

PURPOSE: To review the history of mandatory reporting for the purpose of identifying potential organ and tissue donors, and the controversy around the terms, "imminent" or "impending" death, and to suggest a solution to this controversy. SOURCE: In this narrative review, published papers were retrieved based on a Medline search using the terms, "mandatory reporting" and "organ donation." In addition, unpublished data from the United Network for Organ Sharing and the Pennsylvania Gift of Life Program were reviewed. PRINCIPAL FINDINGS: There has been no demonstrable effect of mandatory reporting of "imminent" death independent of educational activities on numbers of organ donors or organs transplanted. Furthermore, mandatory reporting of "imminent" death does not meet criteria of an acceptable screening test. CONCLUSION: Education of health care providers about eligibility for organ and tissue donation and about whom to report as a potential donor will hopefully lead to identification of more individuals who meet criteria for organ donation and who will go on to donate organs to the many potential recipients.

Leprosy case detection using schoolchildren.

An innovative method that combined awareness creation with screening of high school students by their peers was undertaken in 26 randomly selected schools in the project area of the Schieffelin Leprosy Research and Training Center, Karigiri, Vellore, India. This method entailed educating teachers and student leaders in grades 8-12 about leprosy and how to suspect leprosy among their peers. The student leaders in turn conducted a similar awareness programme for their peers and encouraged them to report if they suffered from any skin problem or skin lesion. Based on the reporting by their peers, the class leaders prepared a 'suspect list'. Within a fortnight of the awareness program, a trained leprosy worker visited the school and examined all the students on the 'suspect list'. Those diagnosed to have leprosy were referred to a medical officer, who then confirmed the diagnosis and initiated treatment. Among the 23,125 students enrolled in the 26 randomly selected schools, 234 student leaders were educated about leprosy and trained to detect suspect lesions among their peers. A total of 2200 (9.5%) children reported with skin lesions to their leaders and after screening by a leprosy supervisor and confirmation by a medical officer, 14 new cases (NCDR 6.05/10,000) were detected. This rate was found to be comparable with case detection rates of annual school surveys done during the National Leprosy Eradication Programme (NLEP), when all schoolchildren were examined. The paper suggests that schoolchildren can be used effectively in leprosy case detection and this method has the additional advantage of creating awareness among them, their teachers and communities.

Neuropsychology and multiple sclerosis: diagnostic and rehabilitative approaches.

The frequency of cognitive deficits in multiple sclerosis (MS) patients is rather high and the estimates vary between 43% and 72% depending on the patient samples studied as well as on the methods of cognitive assessment. Despite the great impact of cognitive dysfunction on several aspects of the quality of life, the importance of accurate assessment and rehabilitation of neuropsychological deficits in MS patients has long been ignored. In this article, we first describe tests for the assessment of impairments, disabilities and handicaps. We emphasize that after screening with brief assessment instruments, detailed testing of the basic target deficits is mandatory for the planning of special cognitive training programs. Second, the correlation of certain cognitive deficit patterns with important magnetic resonance imaging (MRI) variables such as total lesion area, size of the corpus callosum and specific lesion location is outlined in detail. Third, some recommendations are made with regard to general rehabilitation principles such as restitution, compensation and adaptation as well as for special rehabilitation techniques including cognitive retraining of basic deficits and/or training of activities of daily living. Finally, we emphasize that there is a need for the development of tailor-made neuropsychological rehabilitation techniques for MS patients, which take into account the course and stage of the disease as well as the specific psychosocial problems of the individual patient.

HIV prevention in Hungary.

Hungary is a country with relatively low HIV prevalence. Since 1989, a wide range of HIV prevention projects has been developed both by government agencies and by an increasingly active voluntary sector. While energy and resources continue to be invested in HIV information and education, some senior public health officials have argued that it is the country's compulsory HIV testing and compulsory reporting system which have enabled it to maintain its low seroprevalence levels. The testing and reporting system are soon to be reformed, however, in response to growing demands for better protection of personal privacy and confidentiality. Whether or not the forthcoming reforms will have an impact on HIV prevention, and what the nature of this impact will be, remain to be seen.

The unrecognised French BSE epidemic.

In France, implementation of systematic screening programs in 2000, as a complement to the mandatory reporting of animals with clinical signs of BSE (passive surveillance), revealed certain limitations of the mandatory system. Indeed, systematic screening showed that some BSE cases were not detected by the clinical surveillance system, implying considerable BSE case under-reporting throughout the epidemic. As the most likely explanation for variant Creutzfeldt-Jakob disease (vCJD) is exposure to the aetiologic agent of BSE, it is essential to reconstruct the French BSE epidemic pattern accounting for this under-reporting. We estimated age- and year-specific incidence rates of BSE by using a back-calculation method. This approach relies on the principle that the number of clinical BSE cases is the consequence of the number of BSE-infected animals after a known incubation time, defined as the time between infection and clinical onset. We generalized this model to take into account epidemiological characteristics of BSE, such as French cattle mortality, BSE case reporting probability, and age-dependent susceptibility and/or exposure to the BSE agent. We confirmed that the average BSE incubation period is five years and that the peak risk of bovine infection occurs between 6 and 12 months of age. The results also showed that the proportion of underreporting is the most influential parameter in the model, and that BSE was substantially underreported until rapid tests were introduced. Indeed, only 103 BSE cases were detected by passive surveillance up to June 2000, while we estimated that there was 301 200 (95% confidence interval (CI) [27 600-837 600]) cattle infected by the BSE agent. Despite uncertainty over the beginning of the epidemic, we showed that the French BSE epidemic in the late 1980s was completely undetected, and only the second wave, after 1990, was observed.

Food for thought in women's health. The gynecologist: the new European gatekeeper in Chlamydia trachomatis infection.

Genital Chlamydia trachomatis infection is the principal cause of bacterial sexually transmitted disease in industrialized countries. A wide spectrum of pathologic conditions has been associated with the disease ranging from urethritis, cervicitis, to pelvic inflammatory disease, ectopic pregnancy, tubal infertility and cervical neoplasia. Screening for genital Chlamydia infection may prevent its serious complications. The need of a comprehensive European screening policy has been recently underlined by PACMeR's scientific committee. Anyhow invitational screening programs are only at the beginning. Chlamydia trachomatis control ''orphan'' and women's health at risk. Until organized programs are developed, implementation of opportunistic screening is mandatory. Since the infection is more commonly observed among juvenile females proper testing of the young women is recommended. As asymptomatic young women in reproductive age are more eager to visit gynaecologists for periodical gynaecological examination and councelling (cervical cytology, breast examination, contraception and family planning), gynaecologist represents the only specialist able to provide early diagnosis of Chlamydia trachomatis. Gynaecologists are called to play a new role in public healthcare, being ''gatekeepers'' for the early detection of the disease, emphasizing their crucial part in young women's health.

Hot cooking oil burns: a 20-year experience.

Hot cooking oil burns resulted in 316 admissions to the Burns Unit at The Royal Brisbane Hospital between January 1, 1981, and December 31, 2000. Notable demographics of this group were a male:female ratio 1.74:1 and that 24% of all patients were between the ages of 16 and 20. Workplace burns accounted for 6% of admissions only, but these tended to be of a larger total body surface area involvement. The mean duration of admission was 8.5 days, with 40% of patients undergoing surgical débridement and split-skin grafting. Two hundred thirty-nine patients had 5% or less TBSA burned, most commonly involving the hands, legs, feet, and the forearms. No patients in our study died. The proportion of patients undergoing débridement and grafting increased from zero patients at commencement of this study to a peak of 82.5% in 1998. We believe this reflects changing practice with earlier excision and grafting trying to achieve the best functional and cosmetic results. The lack of predisposing factors and the accidental nature of these burns mean appropriate prevention strategies are paramount to decreasing the number of burns of this type. Suggestions discussed include school-based education programs, warning labels included in product information, and mandatory fire blankets within the home.
