| Globally, burns are a serious public health problem. Burns are the fourth most common type of trauma worldwide, following traffic accidents, falls, and interpersonal violence. An estimated 265 000 deaths occur each year from fires alone, with more deaths from scalds, electrical burns, and other forms of burns, for which global data are not available. Incidence varies by geographic location, socio-economic status, ethnic group, age and sex. Over 96% of fatal fire-related burns occur in low- and middle-income countries. In addition to those who die, millions more are left with lifelong disabilities and disfigurements, often with resulting stigma and rejection. High-income countries have made considerable progress in lowering rates of burn deaths, through combination of proven prevention strategies and through improvements in the care of burn victims. According to the World Health Organization, the highest mortality rates are observed in low and middle income countries with most cases seen in Southeast Asia. Mortality rate among low-income countries is 11 times higher than in high-income countries. For example: In India, over 1 000 000 people are moderately or severely burnt every year. Children under 5 and the elderly have the highest burn mortality worldwide. | Globally, burns are a serious public health problem.

| + | Physician conducts a thorough patient evaluation which includes getting a detailed description of the event that caused the thermal injury, any associated trauma that they may have acquired and pre-existing health conditions that they have. Physician will also ask whether they are having trouble breathing or are feeling pain anywhere else. In addition, he/she will ask whether the patient had lost consciousness at any point - this is a sign for potential inhalation injury (Alharbi et al, 2012). | ||

| + | There are two surveys that are conducted. The Primary Survey looks at A.B.C.D.E.F, which stands for Airway, Breathing, Circulation, Disability, Exposure and Fluid resuscitation. The primary survey is to help get an idea of how the patient can be potentially treated for his/her thermal injury. The Secondary Survey looks at the patient from head-to-toe. The physician will evaluate the burned area, measure the size, depth and surface area of wound. Tetanus shot given to all patients who have a greater than first-degree burn. A tetanus shot (tetanus prophylaxis is given to prevent bacterial infection from the exotocin produced by, Clostridium tetani. With infection, the disease tetanus results. Tetanus is a disease of muscle spasm and rigidity (Alharbi et al, 2012). The disease has a mortality rate of 20% due to spasm and rigidity of respiratory muscles). In the secondary survey, a burn assessment chart will be used to calculate the total body surface area (TSBA) of the burn. This chart is known is the Rule of Nines. Burns greater than 15% in adult, 10% children, and any in elderly is considered serious and would require further hospitalization care. Body is divided into regions of 9%. Morbidity and mortality arises with increased burned surface area (WHO, 2007). | ||

| + | A patient needs to be referred to a specialized burn care facility if the patient has partial thickness burns greater than 10% total body surface area (TSBA), if they have acquired an electrical burn (including lightning injury), if they have an inhalation injury, or if the patient has any pre-existing medical conditions (Alharbi et al, 2012). | ||

| The American Burn Association (ABA) determined the criteria used by primary physicians when sending patients to burn centers. If there are facial burns, a referral is required due to the prospect of psychological and identity issues (Lloyd et al., 2012). Also, patients are sent if there are full-thickness burns or any burns to the hand, feet, perineum and genital area (due to anatomy and physiology of region). Moreover, circumferential burns must also be referred in order to reduce the risk of compartment syndrome (Lloyd et al., 2012). | The American Burn Association (ABA) determined the criteria used by primary physicians when sending patients to burn centers.

| Atiyeh et al. (2009) highlight three main strategies that aim to reduce harm from injuries which include education, product design and environmental change, and legislation and regulation. In the strategies figure, strategies to reduce harm from injuries emphasize an active and passive approach. The educational strategy is an active approach focused on the individual (host) to help them avoid injury by modifying their environment to reduce the likelihood of injury. By knowing the environmental risks, it is more likely that preventative behavior will happen in an individual. Passive injury prevention involves product and environment modification. Product modification can be influenced by education the public to ask for safer products, and they can create pressure on authorities to produce prevention legislations (Atiyeh et al.,2009). | Atiyeh et al.
