Clinical utility and economic impact of introducing a bowel management system.

PURPOSE The primary objective of this study was to compare rates of urinary tract and soft tissue infections in critically ill burn patients before and following introduction of a Bowel Management System (BMS). We also analyzed the economic impact of the BMS as compared to reactive management of fecal soiling via cleansing and dressing changes. METHODS AND MATERIALS A retrospective case-matched before-after study was completed. Critically ill burn patients using a BMS were matched with similar patients managed before introduction of the device based on gender, total body surface area burned, burn location, ventilation days, and hospital length of stay. RESULTS Reductions in hospital-acquired urinary tract infections and skin and soft tissue infections were observed after introduction of the BMS. Despite its initial cost, it proved more cost effective than a reactive bowel management strategy based on cleansing and dressing changes when fecal soiling occurs. CONCLUSIONS Proactive use of a bowel management device appears to reduce some infectious sequelae in a complicated burn care population and proved cost-effective for our facility.

An Open, Prospective, Randomized Pilot Investigation Evaluating Pain With the Use of a Soft Silicone Wound Contact Layer Vs Bridal Veil and Staples on Split Thickness Skin Grafts as a Primary Dressing

An open, prospective, randomized, pilot investigation was implemented to evaluate the pain, cost-effectiveness, ease of use, tolerance, efficacy, and safety of a soft silicone wound contact layer (Mepitel® One) vs Bridal Veil and staples used on split thickness skin grafts in the treatment of deep partial or full-thickness thermal burns. Individuals aged between 18 and 70 years with deep partial or full-thickness thermal burns (1–25% TBSA) were randomized into two groups and treated for 14 days or until greater than 95% graft take was achieved, whichever occurred first. Data were obtained and analyzed on pain experienced before, during, and after dressing removal. Secondary considerations included the overall cost (direct), graft take and healing, the ease of product use, overall experience of the dressing, and adverse events. A total of 43 subjects were recruited. There were no significant differences in burn area profiles within the groups. The pain level during dressing removal was significant between the groups (P = .0118) with the removal of Mepitel One being less painful. The staff costs were lower in the group of patients treated with Mepitel One (P = .0064) as reflected in the shorter time required for dressing removal (P = .0005), with Mepitel One taking on average less than a quarter of the time to remove. There was no significant difference in healing between the two groups, with 99.0% of the Mepitel One group and 93.1% of the Bridal Veil and staples group showing greater than 95% graft take at post-op day 7 (+/−1) (P = .2373). Clinicians reported that the soft silicone dressing was easier to use, more conformable, and demonstrated better ability to stay in place, compared with the Bridal Veil and staples regime. Both treatments were well tolerated, with no serious adverse events in either treatment group. Mepitel One was at least as effective in the treatment of patients as the standard care (Bridal Veil and staples). In addition, the group of patients treated with the soft silicone dressing demonstrated decreased pain and lower costs associated with treatment.

Burns in mobile home fires-descriptive study at a regional Burn Center.

Death from fires and burns are the sixth most common cause of unintentional injury death in the United States. More than ¾ of burn deaths occurring in the United States are in the home. Mobile home fires carry twice the death rate as other dwellings. The aim of the study was to describe the characteristics of deaths and injuries in mobile home fire admitted in a regional Burn Center and to identify possible risk factors. A cross-sectional retrospective study was carried out among all burn patients admitted to a regional Burn Center between January 2002 and December 2004 (3469 patients). The study included patients who suffered a burn injury from a mobile home fire. The demographic characteristics of the patients, location of mobile home, associated inhalation injury, source of fire, comorbidity of the victims, employment status, insurance status, family history of burns, and outcomes of the treatment were incorporated in a data collection record. There were 65 burn patients in mobile home fires admitted to the Burn Center during the studied period. The average age of the patients was 39 years (ranging from 2 to 81 years, SD = 16.06), 77% were male, 67% were white, and 79% were the residents in the suburban areas of Georgia, South Carolina, North Carolina, and Florida. The average TBSA of burns was about 21% (ranging from 1 to 63%, SD = 17.66), 63% of the patients had associated inhalation, three inhalation injury only, and 69% patients required ventilator support. The average length of stay per TBSA percentage of burn was 1.01 days (P = 0.00), controlling for age, preexisting medical comorbidities, and inhalation injury. About 88% of the patients had preexisting medical comorbid conditions, 74% were smokers, 64% reported as alcoholic, and 72% had at least some form of health insurance coverage. In 40% of the cases, the cause of the fire was unknown, 31% were caused by accidental explosions, such as electric, gasoline, or kerosene appliances, and 29% were due to other causes. About 40% of burns took place between December and February. Among the studied cohorts, 32% were unemployed, 15% were disabled, and 14% did not have any information about their employment status. One in every four patients had a family history of a burn. Eight (12%) died in the hospital during treatment. There was a higher prevalence of inhalation injury and higher case fatality among the burn patients in mobile home fires compared with the statistics of the Burn Center. Observation showed a higher number of smokers and alcoholics among the burn patients. The main sources of fire were from home appliances. Fewer people had health insurance coverage than the national standard and more people suffered from some sort of chronic illness compared with the national morbidity data.

Purpura fulminans: a case series managed at a regional burn center.

Purpura fulminans (PF) is a protein C deficiency disease process with a high case fatality rate; however, overall incidence of the disease remains relatively very low. The similarity between skin necrosis secondary to PF and full-thickness skin burns provides the rationale for treating PF case in a burn center. In this case series we reviewed our experiences in managing PF and their associated favorable outcomes. Retrospective chart review of five PF cases managed between September 2004 and August 2006 at our Burn Center with 100% survival. Management of cases following the standard care of the Burn Center for a full-thickness burn included antibiotics, fluid resuscitation, surgical debridement with skin grafting, and activated protein C (Drotrecogin alfa) replacement. Two patients required amputations of extremities and all had surgical debridement. One required hemodialysis and two needed both hemodialysis and positive-pressure mechanical ventilator. No patient experienced any bleeding complications during or after surgery while receiving activated protein C. Early diagnosis and treatment at a burn center may reduce mortality and morbidity and loss of extremities in PF cases.

Care of the Burned Pregnant Patient

Abstract This chapter defines the care of severely burned obstetric patients in the rare event the burn team is faced with this complex physiologic situation. The mortality rates for severely burned pregnant women and their fetuses are the highest among the burn population. The current dearth of literature predominantly advocates treating pregnant women much as nonpregnant victims would be: early wound excision and coverage, aggressive fluid resuscitation, empiric antibiotic coverage, and adequate nutritional support. One distinction is the early administration of antenatal corticosteroids for fetal development. The lower limit of periviability is now gestational week 22 or a fetal weight of 500 g, defining the earliest viable emergent delivery stage. Optimal management requires multidisciplinary cooperation; consultation from high-risk obstetricians, neonatologists, pharmacologists, and psychiatrists ought to augment the burn team. It will be the continuous recommendation of the authors that systematic research be performed on how best to treat both patients, mother and baby.

Renal Replacement Therapy in Severe Burns: A Multicenter Observational Study

Abstract Acute kidney injury (AKI) after severe burns is historically associated with a high mortality. Over the past two decades, various modes of renal replacement therapy (RRT) have been used in this population. The purpose of this multicenter study was to evaluate demographic, treatment, and outcomes data among severe burn patients treated with RRT collectively at various burn centers around the United States. After institutional review board approval, a multicenter observational study was conducted. All adult patients aged 18 or older, admitted with severe burns who were placed on RRT for acute indications but not randomized into a concurrently enrolling interventional trial, were included. Across eight participating burn centers, 171 subjects were enrolled during a 4-year period. Complete data were available in 170 subjects with a mean age of 51 ± 17, percent total body surface area burn of 38 ± 26% and injury severity score of 27 ± 21. Eighty percent of subjects were male and 34% were diagnosed with smoke inhalation injury. The preferred mode of therapy was continuous venovenous hemofiltration at a mean delivered dose of 37 ± 19 (ml/kg/hour) and a treatment duration of 13 ± 24 days. Overall, in hospital, mortality was 50%. Among survivors, 21% required RRT on discharge from the hospital while 9% continued to require RRT 6 months after discharge. This is the first multicenter cohort of burn patients who underwent RRT reported to date. Overall mortality is comparable to other critically ill populations who undergo RRT. Most patients who survive to discharge eventually recover renal function.

Urban-Rural Dichotomy of Burn Patients in Georgia and South Carolina: A Geographic Information System Study.

This study uses a 4-year (2006–2009) cross-section of epidemiological burn injury data from Georgia and South Carolina. The results from the study show that the burn patients from rural areas differ from their urban counterparts in terms of relative burn injury incidence. Younger population groups that live in lower socioeconomic status communities especially in the urban areas are at a higher risk than other population groups. The differences in the types of burns in the urban–rural communities can give us further insights to the patients’ association with injury sites. The presence of fewer burn injury treatment and care facilities in rural areas and the high incidence of burn in low-income communities in the urban areas should carry important policy implications for health planners. This study will enable researchers to understand the epidemiology of burn injuries at the local and national levels in the United States. It also carries important implications for using Geographic Information Systems for studying spatial distribution of burn injuries for disaster planning and mitigation of burn injuries.

Five-Lumen Antibiotic-Impregnated Femoral Central Venous Catheters in Severely Burned Patients: An Investigation of Device Utility and Catheter-Related Bloodstream Infection Rates.

The objective of this study is to determine the catheter-related bloodstream infection (CRBSI) rate in a severely burned patient population, many of whom required prolonged use of central venous catheters (CVCs). Between January 2008 and June 2012, 151 patients underwent placement of 455 five-lumen minocycline/rifampin-impregnated CVCs. CRBSI was defined as at least one blood culture (>100,000 colonies) and one simultaneous roll-plate CVC tip culture (>15 colony forming units) positive for the same organism. Most patients had accidental burns (81.5%) with a mean TBSA of 50%. A mean of three catheters were inserted per patient (range, 1–25). CVCs were inserted in the femoral vein (91.2%), subclavian vein (5.3%), and internal jugular vein (3.3%). Mean overall catheter indwell time was 8 days (range, 0–39 days). The overall rate of CRBSI per 1000 catheter days was 11.2; patients with a TBSA >60% experienced significantly higher rates of CRBSI than patients with a TBSA ⩽60% (16.2 vs 7.3, P = .01). CVCs placed through burned skin were four times more likely to be associated with CRBSI than CVCs placed through intact skin. The most common infectious organism was Acinetobacter baumannii. Deep venous thrombosis developed in eleven patients (7%). The overall rate of CRBSI was 11.2, consistent with published rates of CRBSI in burn patients. Thus, femoral placement of 5-lumen CVCs did not result in increased CRBSI rates. These data support the safety of femoral CVC placement in burn patients, contrary to the Centers for Disease Control recommendation to avoid femoral CVC insertion.
