RESUMO

Anxiety is common among patients with burn injury, occurring frequently surrounding wound care. Few pharmacologic interventions targeting anxiety in burn injury have been evaluated. This study aimed to evaluate patient-controlled anxiolysis using dexmedetomidine (PCA-DEX) in patients undergoing burn dressing changes. This was a prospective, open-label, single-arm pilot study to determine the feasibility, safety, and acceptability of PCA-DEX. PCA-DEX included a loading dose, continuous infusion, and patient-administered boluses during dressing changes for up to 5 days. Vital signs were monitored throughout PCA-DEX. Procedural pain and anxiety were evaluated before and after each dressing change. Nursing and patient satisfaction were evaluated after each dressing change. Twenty patients were included; 9 (45%) males and 11 females (55%) with a mean age of 45.1 ± 16.9 years and median total body surface area burn injury of 7 [IQR 4-9.5]%. Median heart rate and systolic blood pressure prior to PCA-DEX on day 1 were 82 [75-97] bpm and 147 [128-170] mmHg. Overall PCA-DEX was tolerated well with a median heart rate of 72 [66-82] bpm and systolic blood pressure 115 [99-141] mmHg after PCA-DEX. One patient was withdrawn due to severe bradycardia (heart rate < 45 bpm) not attributed to PCA-DEX; 4 patients experienced mild hypotension (systolic blood pressure 85-89/diastolic blood pressure 45-49 mmHg), all of which resolved without intervention. The majority of both nurses and patients were either satisfied or highly satisfied with PCA-DEX overall (78.1% for nursing, 86.5% for patients). PCA-DEX is a novel, safe and feasible method of anxiolysis during burn dressing changes with high patient and nurse satisfaction rates. A randomized, controlled trial is warranted to confirm the efficacy of PCA-DEX.

RESUMO

The data are insufficient to support standardized treatment of all patients with frostbite with thrombolytic therapy. The following guidelines, however, should be applied to all patients with cyanosis persisting proximal to the distal phalanx (Grade 3 or 4 frostbite injury) and demonstrated loss of perfusion at or proximal to the middle phalanx immediately after rewarming.

RESUMO

INTRODUCTION: Patients with thermal burns become zinc deficient due to exudative losses, increased urinary excretion, and reduction of carrier proteins which results in impaired immunity, wound healing and glucose control. Previous trials have demonstrated improved wound healing utilizing fixed zinc supplementation, but none have assessed the potential benefits associated with normalizing serum zinc concentrations. The objective of this study was to compare the impact of zinc normalization on clinical outcomes in patients with severe thermal burns. METHODS: This retrospective, single-center study of patients with at least 10% total body surface area (TBSA) burn and three serum zinc concentrations compared the ratio of hospital length of stay (LOS) over TBSA burned (LOS/TBSA index) between those with normal (≥60 mcg/mL) and non-normal (<60 mcg/mL) serum zinc concentrations; delineated by the third measurement. Secondary outcomes were time to 90% epithelialization, infection incidence, and percentage of blood glucose values greater than 180 mg/dL. Data are reported as median [25-75% interquartile range] for continuous variables and frequency (percent) for categorical variables. RESULTS: A total of 56 patients were included for evaluation (11 normal and 45 non-normal). Burn size was 20.5% TBSA [11-29] for those with normal zinc and 27.3% [22-36] for non-normal; number of grafts for each group was 1 [0-1] vs 2 [1-3] respectively. LOS/TBSA index did not differ significantly between groups (1.10 normal vs. 1.21 non-normal, unadjusted p = 0.69; p = 0.75 adjusting for number of grafts). Time to 90% epithelialization was reduced in the normal group (27.5 vs. 57 days, p = 0.02), but this did not remain statistically significant after adjustment for %TBSA and number of grafts (p = 0.18). The groups did not differ significantly in incidence of infection or hyperglycemia in either unadjusted or adjusted analyses. CONCLUSIONS: This was the first study, to our knowledge, to assess the clinical impact of normalizing serum zinc levels in patients with severe burns. Our results suggest the normalization of serum zinc levels through individualized zinc supplementation is not associated with improvement in clinical outcomes during hospitalization and therefore fixed-dose zinc supplementation without acquisition of serum zinc measurements should be considered.

RESUMO

INTRODUCTION: Recent advances in burn care have resulted in the transition of care from inpatient to outpatient. There is a growing appreciation that with improved survival, meaningful markers of quality need to include recovery of form, function, and reconstruction. Capture of the data describing care delivered in the outpatient setting is being missed. METHODS: Development of our outpatient database included providers, registrar, program manager, and outpatient nursing staff. Data points were included if they described the population, and epidemiology of our patients, were useful for programmatic changes and improvements as well as anticipated research focus areas. RESULTS: The database platform chosen was Midas+™ because it was in use by hospital quality and integrated with the electronic medical record. Fields were customized based on changing program needs and are updated for new programs or outcomes measures. Reports can be easily built and both outpatients and inpatients are included. This allows for longitudinal tracking of burn patients. Ongoing additions to original data points include variables to track outcomes related to laser therapy for scar management, time to custom garment donning, and to track functional outcomes. Epidemiologic data collected is used to target high-risk populations for prevention and outreach efforts. Outcome data is used for evaluation of programs and care. CONCLUSIONS: High quality databases serve to measure effectiveness of care and offer insight for areas of improvement. There is a clear need for inclusion of outpatient activity in the National Burn Registry (NBR).

RESUMO

BACKGROUND: The primary objective of the study was to evaluate the efficacy of 300 milligrams (mg) and 600 mg of pregabalin compared to placebo in the reduction of pain in patients with noncritical partial and full thickness burn injuries. METHODS: A prospective, randomized, double-blinded, single center, placebo-controlled trial was conducted. Simple randomization method was used in this trial. After subjects met all the inclusion and none of the exclusion criteria, they were randomized and assigned to 1 of the 3 18-day treatments groups: Pregabalin 300 group, Pregabalin 600 group, or Placebo group. Demographics and clinical characteristics were recorded. The severity of pain was assessed by using the visual analog scale for pain intensity at baseline on day 3, day 9 ±â€Š3, day 25 ±â€Š7, day 90 ±â€Š6, and day 180 ±â€Š12. RESULTS: A total of 54 subjects were randomly assigned, and 51 were included in the data analysis. Demographics and clinical characteristics did not differ significantly between the 3 groups. There was a statistically significant difference in pain between the Pregabalin 300 and Pregabalin 600 groups (P-value = .0260). The Pregabalin 300 group had 17.93 units (95% confidence interval: 1.83-34.04) higher pain scores on average than the Pregabalin 600 group, regardless of time. The adjusted P-value comparing 0 to 300 was .1618, while the adjusted P-value for 0 versus 600 was .5304. There was an overall difference in pain across time regardless of study group (P-value = <.0001). An overall difference in opioid consumption (P-value = .0003) and BSHS (P-value = .0013) across time regardless of study group was noted. CONCLUSIONS: Pregabalin could be part of a promising multimodal analgesic regimen in noncritical burn population. Future placebo-controlled studies assessing the use of pregabalin in burn victim patients may further endorse our findings.

RESUMO

OBJECTIVE: Compression therapy (CT) has been an important, but debated, treatment for burn scars. To better understand one source of variation in observed outcomes after CT, an evaluation of CT timing of application is needed. MATERIALS AND METHODS: Following IRB approval, 126 burn centers were contacted to complete a 17-question survey regarding the center's practice pattern for compression garment therapy. Locally, study subjects were identified between March 1, 2014 and December 31, 2015 and medical records examined for timing of garment ordering, delivery and fitting. RESULTS: The majority believed that compression therapy is beneficial. Most centers reported using custom-fit and pre-fabricated garments, and a goal time of application between 2-4 weeks (42%) and 4-6 weeks (36%). After the garments are ordered, 61% of centers estimate that it takes 2-4 weeks for them to arrive. No significant differences in practices were found among centers treating pediatric patients only, adults only or both. Locally, the mean number of weeks between the date of original injury and garment order placement was 9.1 weeks with an additional 8.7 weeks between the date of order and date of delivery. CONCLUSIONS: The current study identified that although the national reporting of time to garment application is estimated to be between 2-6 weeks at the majority of burn centers including our own, we found our center to be well in excess of 17 weeks. The findings offer an opportunity for local improvement, and raise the possibility of similar incongruity between goals and practice at other centers.

RESUMO

The benefits of oxandrolone in burn patients has led to its accepted use in the burn care community, however details regarding the most common adverse effect, transaminitis, remains unclear. The purpose of this study was to determine the incidence of transaminitis in patients with burn injury and identify risk factors associated with the development of transaminitis. This single-center, retrospective risk factor analysis compared burn patients on oxandrolone with and without the development of transaminitis, defined as any aspartate aminotransferase or alanine aminotransferase value >100mg/dL. Patient demographics, past medical history, lab values, and burn characteristics were recorded. Overall 28 out of 66 (42%) patients developed transaminitis. The transaminitis group had a significantly higher proportion of other concomitant medications with a transaminitis risk (p=0.045). No significant difference in liver dysfunction or length of stay was observed between the two groups. Oxandrolone induced transaminitis is occurring in patients significantly more frequently than previously reported warranting further research to guide monitoring requirements, use of concomitant medications, and to determine if rechallenging after resolution should be considered.

RESUMO

Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) is a rare, severe mucocutaneous reaction with few large cohorts reported. This multicenter retrospective study included patients with SJS/TEN seen by inpatient consultative dermatologists at 18 academic medical centers in the United States. A total of 377 adult patients with SJS/TEN between January 1, 2000 and June 1, 2015 were entered, including 260 of 377 (69%) from 2010 onward. The most frequent cause of SJS/TEN was medication reaction in 338 of 377 (89.7%), most often to trimethoprim/sulfamethoxazole (89/338; 26.3%). Most patients were managed in an intensive care (100/368; 27.2%) or burn unit (151/368; 41.0%). Most received pharmacologic therapy (266/376; 70.7%) versus supportive care alone (110/376; 29.3%)-typically corticosteroids (113/266; 42.5%), intravenous immunoglobulin (94/266; 35.3%), or both therapies (54/266; 20.3%). Based on day 1 SCORTEN predicted mortality, approximately 78 in-hospital deaths were expected (77.7/368; 21%), but the observed mortality of 54 patients (54/368; 14.7%) was significantly lower (standardized mortality ratio = 0.70; 95% confidence interval = 0.58-0.79). Stratified by therapy received, the standardized mortality ratio was lowest among those receiving both steroids and intravenous immunoglobulin (standardized mortality ratio = 0.52; 95% confidence interval 0.21-0.79). This large cohort provides contemporary information regarding US patients with SJS/TEN. Mortality, although substantial, was significantly lower than predicted. Although the precise role of pharmacotherapy remains unclear, co-administration of corticosteroids and intravenous immunoglobulin, among other therapies, may warrant further study.

RESUMO

This study characterizes adult burn readmissions in the United States using a nationally representative hospital inpatient sample. Readmission rates, diagnoses, and risk factors are discussed. We analyzed the 2013 and 2014 Nationwide Readmission Database for adult burn patients. The data were weighted to estimate national 30-day readmission rates. Principal readmission diagnoses were sorted into burn-specific or other readmission categories. We used multivariable logistic regression to assess the effects of patient and hospital stay risk factors on readmissions. An estimated 42,957 U.S. adult burn patients were discharged between January and November of 2013 and 2014. Of these patients, an estimated 3203 had unscheduled readmissions within 30 days (all-cause readmission rate: 7.5%, 95% CI: 6.7-8.2). An estimated 55.4 per cent of unplanned readmissions were for burn-specific principal readmission diagnoses. Burn-specific readmission was associated with burn severity and increased with both patient age and the number of comorbidities. Patients whose length of stay was less than 1 day per % total body surface area (%TBSA) burned had higher readmission risk (Adjusted odds ratio = 2.10, 95% CI = 1.48-2.99). The results of logistic regression models were similar for burn-specific readmissions and all-cause readmissions. In a nationally representative sample of adult burn patients, 4.1 per cent had unplanned 30-day readmissions for burn-specific reasons; 7.5 per cent were readmitted for any reason. Patient comorbidities and discharge before 1 day per %TBSA from the hospital impact readmission risk. Healthcare providers can use this information to identify at-risk patients, modify their treatment plans, and prevent readmissions.

RESUMO

OBJECTIVE: tPA and anticoagulation for treatment of severe frostbite have been reported suggesting differences in imaging techniques, route of tPA administration and management of patients after tPA infusion. This is a report of our results following a protocol of Tc-99m scanning, intravenous tPA administration, followed by either systemic anticoagulation or antiplatelet therapy. METHODS: Patients admitted to our burn center between February 13, 2015 and February 13, 2016 for frostbite who met inclusion criteria were treated with Tc-99m scan and intravenous tPA followed by systemic anticoagulation or antiplatelet therapy. Inclusion criteria included rewarming had not started more than 24h prior to the scan and no contraindications to the use of tPA. RESULTS: Fifteen patients met inclusion criteria and 12 were treated according to the protocol. Nine received scans with 2 showing normal perfusion. Seven displayed perfusion defects and received intravenous tPA. Five recovered fully after tPA. Two who showed improved but abnormal scans after tPA experienced bleeding complications necessitating stopping heparin/Coumadin. Those two went on to partial amputation of digits. CONCLUSION: The use of intra-arterial or intravenous tPA along with angiography or Tc-99m scanning followed by systemic anticoagulation or antiplatelet therapy may be beneficial to patients suffering frostbite.

RESUMO

INTRODUCTION: Resuscitation from burn shock using fresh frozen plasma (FFP) has been described. Critics of FFP resuscitation cite the development of transfusion related acute lung injury (TRALI) as a deterrent to its use. This study examines the occurrence of TRALI with FFP resuscitation of critically ill burned patients. METHODS: A retrospective chart review was conducted of severely burned patients who received FFP resuscitation. Data points included age, TBSA, TBSA full thickness, presence of alternate etiologies of acute lung injury, total FFP administered, and signs and symptoms of TRALI as defined per the Canadian Blood Services Consensus Conference. RESULTS: Eighty-three patients met the definition of severe burn and received FFP resuscitation. Of those, 65 met exclusion criteria. Eighteen patients were left for analysis with only one found to have signs and symptoms of TRALI. That patient suffered a 53.5% TBSA burn, received a total of 6228ml FFP, had no competing etiologies of ALI, and was diagnosed with TRALI within 6h of completing the FFP transfusion. CONCLUSION: The possible occurrence of TRALI in burn patients receiving FFP resuscitation should be weighed against the reported benefits of such a resuscitation strategy.

RESUMO

Currently, there have been few studies that have evaluated the incidence of vitamin D deficiency in adult burn patients or correlated vitamin D levels with burn-related outcomes. The primary objective of the study was to identify the incidence of vitamin D deficiency and insufficiency in an adult burn population. The secondary objective was to determine the impact of vitamin D deficiency and insufficiency on clinical outcomes in burn care. A single-center, retrospective, and observational cohort analysis of adult patients admitted for initial management of burn injury, who had a 25-hydroxyvitamin D (25D) level measured on admission, was performed. Patients were categorized as vitamin D deficient (25D <10 ng/ml), insufficient (10-29 ng/ml), or sufficient (30-100 ng/ml) based on admission measurements. Clinical outcomes including complications, intensive care unit (ICU) and hospital length of stay (LOS), and survival were compared between patients with vitamin D deficiency/insufficiency and patients with vitamin D sufficiency. Three-hundred and eighteen patients were eligible for evaluation. Admission 25D level correlated with deficiency in 46 patients (14.5%), insufficiency in 207 (65.1%), and normal in 65 (20.4%). Patients with vitamin D deficiency or insufficiency experienced higher rates of complications and longer ICU and hospital LOS compared with those with normal vitamin D levels. A large proportion of patients with burn injury presented with vitamin D insufficiency and deficiency which was associated with poor outcomes, including prolonged ICU and hospital LOS. Additional studies are needed to further describe the relationship between vitamin D status and clinical outcomes.

RESUMO

It is generally agreed that patients with large burns will be referred to organized burn centers, however, the referral of patients with smaller burns is less certain. A two-part survey was conducted to identify referral patterns for burn patients that meet American Burn Association referral criteria, and any effect insurance type might have on the referral patterns. The emergency departments of our state hospital association's member hospitals were contacted seeking a referral for a fictitious patient with a third-degree scald of the dominant hand. The referral sites were contacted twice, first stating that the patient had commercial insurance, next stating that the patient had Medicaid. Data collected included wait time for an appointment or reasons for denial of an appointment. Of 218 hospitals, 46 were excluded because they did not offer emergency care, and eight because they were listed as burn centers on the American Burn Association website. Of the remaining 164, 119 (73%) would refer to a burn center, 21 (13%) to a plastic surgeon, 10 (6%) to a hand surgeon, 7 (4%) to a wound center, 7 (4%) to another nonburn physician resource. There was no difference in wait time to the first available appointment with regards to insurance type (6.56 ± 4.68 vs 6.53 ± 5.05 days). Our state's referral pattern gives us insight into the regional referral pattern. This information will be used to guide a focused education and communication program to provide better service for the burn victims of our state.

RESUMO

Infection control is a critical component of post-burn care with prevention of infection serving as a major cause of decreasing morbidity and mortality. One potential deterrent for infection is barrier protection during dressing changes; however, no evidence-based standard has been established among burn centers. The purpose of this study is to describe the current barrier techniques of American burn centers. A 24-question survey was sent to 121 burn center nurse managers within the United States. The survey was comprised of yes or no questions with comment sections available for further detail. Questions were constructed to gain insight into the variation and commonality that may exist between burn center barrier protocols. Forty-one out of 121 centers (34%) responded. Centers reported the use of head covers, masks, gowns, and gloves during admission of a new burn (71%, 82%, 95%, and 100% respectively); daily dressing changes (64%, 80%, 97%, and 100% respectively); postoperative dressing changes (64%, masks 80%, 97%, and 100% respectively); and dressing changes of a nonburn (66%, 82%, 97%, and 100% respectively). Burn centers reported their use of sterile gloves and gowns during typical burn dressing changes as occurring 20% and 10% of the time, respectively. Estimates for costs of these garments annually ranged from $0 to $250,000. A calculation performed for this study demonstrated that barrier garments used for dressing changes nationwide is approximately $2.43 million. We demonstrated the immense cost, to an institution and nationwide, of barrier garments used solely for dressing changes.

RESUMO

The junctional sarcoplasmic reticulum (jSR) is an important and unique ER subdomain in the adult myocyte that concentrates resident proteins to regulate Ca(2+) release. To investigate cellular mechanisms for sorting and trafficking proteins to jSR, we overexpressed canine forms of junctin (JCT) or triadin (TRD) in adult rat cardiomyocytes. Protein accumulation over time was visualized by confocal fluorescence microscopy using species-specific antibodies. Newly synthesized JCTdog and TRDdog appeared by 12-24h as bright fluorescent puncta close to the nuclear surface, decreasing in intensity with increasing radial distance. With increasing time (24-48h), fluorescent puncta appeared at further radial distances from the nuclear surface, eventually populating jSR similar to steady-state patterns. CSQ2-DsRed, a form of CSQ that polymerizes ectopically in rough ER, prevented anterograde traffic of newly made TRDdog and JCTdog, demonstrating common pathways of intracellular trafficking as well as in situ binding to CSQ2 in juxtanuclear rough ER. Reversal of CSQ-DsRed interactions occurred when a form of TRDdog was used in which CSQ2-binding sites are removed ((del)TRD). With increasing levels of expression, CSQ2-DsRed revealed a novel smooth ER network that surrounds nuclei and connects the nuclear axis. TRDdog was retained in smooth ER by binding to CSQ2-DsRed, but escaped to populate jSR puncta. TRDdog and (del)TRD were therefore able to elucidate areas of ER-SR transition. High levels of CSQ2-DsRed in the ER led to loss of jSR puncta labeling, suggesting a plasticity of ER-SR transition sites. We propose a model of ER and SR protein traffic along microtubules, with prominent transverse/radial ER trafficking of JCT and TRD along Z-lines to populate jSR, and an abundant longitudinal/axial smooth ER between and encircling myonuclei, from which jSR proteins traffic.

RESUMO

Advancing age is associated with increased mortality despite smaller burn size. Chronic conditions are common in the elderly with resulting polypharmacy. The Comorbidity-Polypharmacy Score (CPS) facilitates quantitative assessment of the severity of comorbid conditions, or physiologic age. Burn injury in older patients is associated with increasing morbidity and mortality and the CPS may be predictive of outcomes such as mortality, ICU and hospital LOS, complications, and final hospital disposition. Our goal was to evaluate the predictive value of CPS for outcomes in the elderly burn population. A retrospective study was undertaken of 920 burn patients with age ≥45 admitted with acute burn injuries (January 1, 2006 to December 31, 2012). CPS was calculated by adding preinjury comorbidities and medications. Subjects were stratified into three groups according to CPS severity. Data collected included demographics, total body surface area burned (TBSA), presence of inhalation injury, ICU/hospital length of stay, complications, discharge disposition, and mortality. Univariate and multivariate analyses were performed. The mean age was 55.7; 72.9% were males; the mean initial TBSA was 6.93%; and mean CPS was 8.01. The risk of in-hospital complications is independently associated with CPS (OR 1.35). CPS (OR 1.81) was an independent predictor of discharge to a facility CPS but not of mortality. While increasing CPS was associated with lower TBSA, mortality remained unchanged. CPS is an independent predictor of in-hospital complications and need for transfer to extended care facilities in older burn patients, which can be determined at the stage of admission to help direct patient management.

RESUMO

Phospholamban (PLB) inhibits the activity of cardiac sarcoplasmic reticulum (SR) Ca(2+)-ATPase (SERCA2a). Phosphorylation of PLB during sympathetic activation reverses SERCA2a inhibition, increasing SR Ca(2+) uptake. However, sympathetic activation also modulates multiple other intracellular targets in ventricular myocytes (VMs), making it impossible to determine the specific effects of the reversal of PLB inhibition on the spontaneous SR Ca(2+) release. Therefore, it remains unclear how PLB regulates rhythmic activity in VMs. Here, we used the Fab fragment of 2D12, a monoclonal anti-PLB antibody, to test how acute reversal of PLB inhibition affects the spontaneous SR Ca(2+) release in normal VMs. Ca(2+) sparks and spontaneous Ca(2+) waves (SCWs) were recorded in the line-scan mode of confocal microscopy using the Ca(2+) fluorescent dye Fluo-4 in isolated permeabilized mouse VMs. Fab, which reverses PLB inhibition, significantly increased the frequency, amplitude, and spatial/temporal spread of Ca(2+) sparks in VMs exposed to 50 nM free [Ca(2+)]. At physiological diastolic free [Ca(2+)] (100-200 nM), Fab facilitated the formation of whole-cell propagating SCWs. At higher free [Ca(2+)], Fab increased the frequency and velocity, but decreased the decay time of the SCWs. cAMP had little additional effect on the frequency or morphology of Ca(2+) sparks or SCWs after Fab addition. These findings were complemented by computer simulations. In conclusion, acute reversal of PLB inhibition alone significantly increased the spontaneous SR Ca(2+) release, leading to the facilitation and organization of whole-cell propagating SCWs in normal VMs. PLB thus plays a key role in subcellular Ca(2+) dynamics and rhythmic activity of VMs.

RESUMO

OBJECTIVES: A multidisciplinary team developed an evidence-based guideline for the management of foot burns occurring in diabetic patients that included transcutaneous oxygen measurements (TCOM) and application of hyperbaric oxygen therapy (HBOT) to selected patients. This report represents an evaluation of preliminary TCOM/HBOT data. METHODS: This is a retrospective review of patients with diabetes mellitus (DM) who were admitted to a single American Burn Association (ABA) verified burn center for the treatment of foot burns. Patients were treated via the guideline if they were over the age of 16, admitted for the initial care of burns involving the feet between 4/01/2012 and 7/22/2013, and had a known or new diagnosis of DM. RESULTS: Eighteen patients were treated according to the guideline, 14 men and 4 women. Average age was 54 years+14.78. Average BMI was 30.63+6.34. Median burn size was 0.88% TBSA (median partial thickness of 1% and median full thickness of 0.5%). The average HbA1c was 9.08+2.42. Seven patients received pre-operative HBOT, two received post-operative HBOT and three patients healed their wounds with HBOT alone. Average hospital length of stay was 13.39 days+9.94 and was significantly longer for the group receiving HBOT. Admission HbA1c was not a predictor of the need for HBOT. CONCLUSIONS: While TCOM/HBOT therapy has not been widely applied to the management of diabetic foot burns, the use of an evidence-based guideline incorporating TCOM/HBOT can provide a systematic way to evaluate the patients' microcirculation and ability to heal burns of the foot. The incorporation of TCOM determination and application of HBOT in selected patients with DM and burns of the feet warrant continued study.

RESUMO

INTRODUCTION: Diabetes mellitus affects 25.8 million Americans and is predicted to almost double by 2050. The presence of diabetes complicates hospital courses because of the microvascular complications associated with disease progression. Patients with diabetes represent 18.3% of annual burn admissions to our unit and 27% have burns to the feet. The purpose of this project was to develop an evidence-based guideline for care of the patient with diabetes and foot burns METHODS: A multidisciplinary group was charged with developing an evidence-based guideline for the treatment of foot burns in patients with diabetes. Evidence was evaluated in the areas of diabetes, burn care, hyperbaric medicine, care of diabetic foot wounds and physical therapy. After guideline development and approval, key aspects were incorporated into order sets. RESULTS: Key aspects of this guideline are the ability to identify patients with undiagnosed diabetes, assess diabetic control, optimize glycemic and metabolic control, optimize burn wound management, treat microvascular disease, and provide education and a discharge plan. Evaluated outcomes are glycemic control, length of stay, complication rates, amputation rates, infection rates and the use of hyperbaric oxygen. CONCLUSIONS: Best outcomes for this high risk population will be attainable with an evidence based guideline.
