Nosocomial Infection Among Burn Patients Admitted to a Tertiary Care Hospital of Bangladesh: A Cross-Sectional Study

Nosocomial infection is a major challenge for the appropriate management of burns. The present study aimed to investigate incidence, risk factors, and causative organisms of nosocomial infection in burn patients of Khulna, Bangladesh. This cross-sectional study was conducted among patients admitted to the Burn and Plastic Surgery Department of Khulna Medical College Hospital (KMCH) from January to December 2020. Relevant data were collected from the patients' hospital records. Samples of wound swabs and blood were collected and cultured in the microbiology laboratory of KMCH. Logistic regression models were used to determine risk factors for infective complications in burn patients. All statistical analyses were carried out using SPSS version 26.0. A total of 100 burn patients were included. Mean age was 29.2 years with a male-female ratio of 1.3:1. Flame burns were most prevalent among the patients (41%), followed by scald (23%) and electric burns (15%). Almost 40% patients had full thickness burn. The incidence of nosocomial infection was 42% (wound infection 33% and septicemia 9%). Total body surface area of burn >40% (OR 7.56, 95% CI 2.89-19.81), full thickness burn (OR 34.40, 95% CI 3.25-97.14) and prolonged hospital stay (aOR 1.31, 95% CI 1.15-1.51) were significant risk factors for nosocomial infection. Staphylococcus aureus was the most commonly isolated organism (45%), followed by Streptococcus (24%), Pseudomonas aeruginosa (19%) and Escherichia coli (12%). As the epidemiology of nosocomial infection is not the same in different health facilities, a facility-based comprehensive burn management protocol considering the local epidemiology and causative organisms of burn wound infection is crucial for the prevention and management of nosocomial infections in burn patients.

A content analysis of scald first aid information on Chinese websites

OBJECTIVE

With the rapid development of networks in China, the Internet has become an important source of first aid information for scalds. As a country with the largest population, there are a large number of scald cases every year in China. The content analysis of websites aimed to assess the accuracy and quality of the information on scalds available on Chinese websites.

METHODS

Using keywords related to scald in the most popular Chinese search engines, 19 sites were eventually selected for evaluation based on the inclusion and exclusion criteria. These websites were assessed on quality and content accuracy by using HONcode, DISCERN, and Patient Education Materials Assessment Tool (PEMAT) evaluation scales, and a modified evaluation system based on the system developed by J.D. Burgess. The evaluation was completed by a 5-person evaluation team. The subjective items were reviewed by five independent reviewers. The objective items were recorded by one reviewer, then another checked the results.

RESULTS

Using "scald first aid," "scald treatment," and "scald blister" to search on Baidu, Sougou, and Haosou, a total of 180 websites were recorded. According to the inclusion and exclusion criteria, 19 websites were obtained for assessment. Among them, 17 websites (89%) were established by commercial companies. Of the remaining two websites, one was created by a government agency and the other was created by a non-profit organization. The mean total HONcode score, DISCERN score, PEMAT (understandability) score, PEMAT (actionability) score, content accuracy score, and website quality score were 5.19 ± 1.09 out of 8; 52.63 ± 3.69 out of 80; 68%; 56%; 5.05 ± 1.47 out of 8; and 6.11 out of 12, respectively. The scores of the government agency website are better than that of commercial websites.

CONCLUSION

The websites established by government agencies and non-profit organizations are few, and most of the websites are established by commercial companies. Compared with the government agency website, these commercial websites contain many advertisements, and their website quality and accuracy need to be further improved.

The Descriptive Epidemiology and Outcomes of Hospitalized Burn Patients in Southern Turkey: Age-Specific Mortality Patterns

The current descriptive analysis was designed to document the common epidemiologic characteristics and outcomes of burn injuries, and age-specific mortality patterns covering all age groups admitted for treatment to the Burn Center of Adana City Training and Research Hospital. Medical records were retrospectively analyzed. The patients were stratified into two age groups as pediatric and adults, and then into 10 sub-age groups. Among the 946 patients of the study population, there were 24 mortalities with a mortality rate of 2.5%. Patients within the age range of 70 to 79 years had the highest mortality rate of 33.3%; followed by 60 to 69, 80+, 18 to 29, 10 to 17, and <5 sub-age groups, whose mortality rates were 13.0%, 7.8%, 7.2%, 2.4%, and 0.5%, respectively. In terms of multivariate regression analysis of factors predicting mortality among burn patients in all age groups, fire-flame related burns, age ≥18 years, TBSA burned ≥20% (TBSA ≥20%), the existence of inhalation injury, deep partially/full-thickness burns were found to be significant prognostic factors of mortality. The strongest association was seen in TBSA ≥60% segment (P < .0001), which had 25.9 times more death risk. As expected, a similar trend was detected when the age groups stratified into age groups, and the strongest association was in the 60+ sub-age group (P < .0001), whose had 5.84 times more likely death; followed by 29 to 59 and 18 to 29 sub-age groups, with the odds ratios of 2.12 (95% confidence interval = 1.25-3.61) and 2.08 (95% confidence interval = 1.90-4.05), respectively. Oppose to these findings; the 0 to 17 sub-age group was not found to have a statistically significant effect in predicting mortality.

Comparative evaluation of three methods of skin graft fixation for split thickness skin graft after release of post burn contracture of the neck

OBJECTIVES

Split thickness skin graft is an essential component of release of post burn contracture of neck. There are many methods of fixation of skin grafts; however, there is lack of objective comparison between different techniques. This study has been designed to compare three commonly used techniques of split thickness skin graft fixation methods. Surgical time, advantages, cost factor and post-operative outcome have been compared amongst three techniques.

METHODS

A randomized interventional comparative study was conducted to compare three methods of skin graft fixation in patients of 10-50 years age group, with contracture of more than 3 month duration having more than 100cm² skin defects after contracture release. Resurfacing of the defects after contracture release was carried out in all the groups using autologous split skin grafts. Patients were included in three groups; Group 1: tie over method, Group 2: skin stapler fixation and Group 3: Cyanoacrylate glue fixation.

RESULTS

Mean duration of fixation procedure was 34min in tie over group, in skin stapler group 7min and in cyanoacrylate group 12min. Mean cost of fixation material was 10.23 USD in tie-over group, 11.23 USD in stapler group and 40.06 USD in cyanoacrylate group. Mean score of pain/discomfort (visual analog score) on dressing removal in tie-over group was 3, for skin stapler group was 2.9 and that for cyanoacrylate glue group was 1.8. mean graft take was found to be 90.1% in tie-over group, 94.1% in skin stapler group & 93.8% in cyanoacrylate glue group. On logistic regression analysis, keeping all the variables constant in the groups the complications as the outcome variable, three groups are comparable. The need for regrafting remains inconclusive.

CONCLUSIONS

Skin stapler method for skin graft fixation was least time consuming, affordable and highly reliable when graft take success was considered. Cyanoacrylate glue fixation method was least painful and reliable in terms of graft take success though costlier than other two.

Clinical and demographic features of burn injuries in karachi: a six-year experience at the burns centre, civil hospital, Karachi

Burn injuries are a leading cause of morbidity and mortality, with 195,000 deaths annually. This study was conducted to identify the demographics of burn victims and the effect of different variables on the outcome of their injuries. 4016 patients admitted to the Burns Centre, Civil Hospital Karachi from January 2006 to December 2011 were retrospectively analyzed. Demographics, burn injury details and their outcome were recorded in a pre-designed questionnaire. Injuries were categorized as: fire, chemical, scald or electrical. To estimate total body surface area (TBSA) burned in adults, the rule of nines was used. For children and infants, the Lund-Browder chart was employed. SPSS v16.0 software was used for analysis. Frequencies and percentages of all variables, and the measure of central tendencies and dispersion for continuous variables were calculated. Cross tabs were used to assess mortality. Mean age was 28.13 years. More than half of the cases (n=2337, 58.2%) were aged between 16-30 years. Labourers, housewives and students were the most commonly affected groups. Burn injuries by flame/fire and electricity were most common. Most cases were accidental, followed by suicide attempts and homicides. Mean percentage of TBSA affected was 35.49%. Mean duration of hospital stay was 16.45 days. 50.6% of the expired cases were females. The mean age of expired patients was 30.07 while for patients who survived it was 27.01 years. The outcome of burn injuries is related to various demographic factors. Female gender, increasing age, burn injuries following suicide attempts and greater surface area involvement predict poor outcome.

Blood pressure alterations in burn patients with septic shock under hydro-cortisone treatment

BACKGROUND AND OBJECTIVES

Hydrocortisone is widely used in septic shock cases resistant to fluid and vasopressor therapy. It may result in increased blood pressure and survival. However the efficacy is no established among patients with severe burn and septic shock. Accordingly it was assessed in this study.

MATERIALS AND METHODS

The patients older than 14 years of age with resistant septic shock were enrolled during one-year period. The hydrocortisone was prescribed 100 mg three times per day and the alterations in systolic and diastolic blood pressures were recorded.

RESULTS

Twenty-nine patients were enrolled including 19 men and 10 women. The mean age was 37 ± 19 years and the mean burn surface area was 60 ± 20. Fourteen patients had positive blood culture. The most common isolated microorganism were Pseudomonas aeuroginosa in 34.6%(10 cases), and then Acinetobacter in 13.8%(4 cases). The infection was from wound in 79% and the remaining 21% had pneumonia. Twenty-one patients had good response to hydrocortisone and the increase in systolic and diastolic blood pressures was significant; but the mortality rate was similar.

CONCLUSION

Treatment with hydrocortisone would result in increase in systolic and diastolic blood pressure in burn patients with resistant septic shock.

Coexistence of Extended Spectrum Beta-Lactamases, AmpC Beta-Lactamases and Metallo-Beta-Lactamases in Acinetobacter baumannii from burns patients: a report from a tertiary care centre of India

Multidrug-resistant Acinetobacter baumanii is a major pathogen encountered in pyogenic infections, especially from burns patients in hospital settings. Often there is also coexistence of multiple beta-lactamase enzymes responsible for beta-lactam resistance in a single isolate, which further complicates treatment options. We conducted a study on burn wound pus samples obtained from the burns unit of our hospital. Phenotypic tests were used to determine the Extended Spectrum Beta-Lactamase, AmpC Beta-Lactamase and Metallo-Beta-Lactamase producing status of the isolates. Almost half of the samples from the burn wounds yielded Acinetobacter baumanii as the predominant pathogen (54.05%). Coexistence of the three resistance mechanisms was seen in 25 of the 100 (25%) isolates of Acinetobacter baumanii. This study emphasizes the need for the detection of isolates that produce these enzymes to avoid therapeutic failures and nosocomial outbreaks.

Three-year review of bacteriological profile and antibiogram of burn wound isolates in Van, Turkey

The risk of infection in burns is well-known. In recent decades, the antimicrobial resistance of bacteria isolated from burn patients has increased. For this reason, a retrospective study was conducted at Van Training and Research Hospital to analyze the bacterial isolates from the wounds of patients admitted to the Burn Unit and to determine the susceptibility patterns of the commonly cultured organisms over a 3-year period, January 2009 to December 2011.A total of 250 microorganisms were isolated from burn wounds of 179 patients. Our results revealed that the most frequent isolate was Acinetobacter baumannii (23.6%), Pseudomonas aeruginosa (12%), Staphylococcus aureus (11.2%), Escherichia coli (10%) respectively. Multidrug-resistance has emerged as an important concern in our burn unit. Tigecycline, and colistin were found to be the most active drugs against Acinetobacter baumannii. Carbapenems and amikacin, were found to be the most active drugs against other gram negative bacteria. Vancomycin and linezolid were active against gram positive bacteria.Aggressive infection control measures should be applied to limit the emergence and spread of multidrug-resistant pathogens.

Reduced endothelial function in the skin in Southeast Asians compared to Caucasians

BACKGROUND

The reaction of vascular endothelial cells to occlusion and heat in Southeast Asian Indians (SAI) compared to Caucasians (C) has not been studied, although genetic differences are found in endothelial cells between the races.

MATERIAL/METHODS

Ten C and Ten SAI (<35 years old) male and female subjects participated. There was no difference in the demographics of the subjects except that the SAI group had been in the United States for 6 months; C was natives to the US. Endothelial function was assessed by the response of the circulation (BF) to local heating and the response to vascular occlusion. The effects of local heat on circulation in the skin on the forearm was assessed by applying heat for 6 minutes at temperatures, 38, 40 and 42°C on 3 separate days. On different days, vascular occlusion was applied for 4 minutes to the same arm and skin blood flow was measured for 2 minutes after occlusion; skin temperature was either 31°C or 42°C.

RESULTS

When occlusion was applied at a skin temperature of 31°C, the BF response to occlusion was significantly lower in the SAI cohort compared to C (peak BF C = 617 ± 88.2 flux, SAE = 284 ± 73 flux). The same effect was seen at skin temperatures of 42°C. The circulatory response to heat was also significantly less in SAI compared to C at each temperature examined (p<0.05)(for temperatures of 38, 40 and 42°C, peak blood flow for C was 374.7 ± 81.2, 551.9 ± 91.3 and 725.9 ± 107 flux respectively and 248.5 ± 86.2, 361.4 ± 104.3 and 455.3 ± 109.7 flux respectively for SAI. (p<0.05).

CONCLUSIONS

Thus there seems to be big differences in these 2 populations in endothelial response to these stressors. The difference may be due to genetic variations between the 2 groups of subjects.
