RESUMO
BACKGROUND: Community-acquired Staphylococcus aureus (CA-Sa) skin and soft tissue infections (SSTIs) are historically associated with densely populated urban areas experiencing high poverty rates, intravenous drug use, and homelessness. However, the epidemiology of CA-Sa SSTIs in the United States has been poorly understood since the plateau of the Community-acquired Methicillin-resistant Staphylococcus aureus epidemic in 2010. This study examines the spatial variation of CA-Sa SSTIs in a large, geographically heterogeneous population and identifies neighborhood characteristics associated with increased infection risk. METHODS: Using a unique neighborhood boundary, California Medical Service Study Areas, a hotspot analysis, and estimates of neighborhood infection risk ratios were conducted for all CA-Sa SSTIs presented in non-Federal California emergency departments between 2016 and 2019. A Bayesian Poisson regression model evaluated the association between neighborhood-level infection risk and population structure, neighborhood poverty rates, and being a healthcare shortage area. RESULTS: Emergency departments in more rural and mountainous parts of California experienced a higher burden of CA-Sa SSTIs between 2016 and 2019. Neighborhoods with high infection rates were more likely to have a high percentage of adults living below the federal poverty level and be a designated healthcare shortage area. Measures of population structure were not associated with infection risk in California neighborhoods. CONCLUSIONS: Our results highlight a potential change in the epidemiology of CA-Sa SSTIs in California emergency departments. Future studies should investigate the CA-Sa burden in other geographies to identify whether this shift in epidemiology holds across other states and populations. Further, a more thorough evaluation of potential mechanisms for the clustering of infections seen across California neighborhoods is needed.

Necrotizing soft-tissue infection (NSTI) is a medical emergency. We investigated the impact of racial, socioeconomic disparities, and comorbidities on mortality, complications, length of stay, and charges in patients with NSTI.Data were acquired from the National Inpatient Sample from Q4 2015 to 2017. ICD-10, Clinical Modification codes were utilized to identify relevant cases. Logistic regression was used to assess socioeconomic, racial, and health risk factors for adverse outcomes in NSTI patients.Of 16,071,053 cases identified during the study period, 15,078 (0.094%) NSTI cases were recognized. Black patients had increased odds of amputation (OR 1.40 95% CI 1.24-1.58, p < 0.001), prolonged hospital stay (OR 1.40 95% CI 1.24-1.58, p < 0.001), excessive charges (OR 1.22 95% CI 1.03-1.43, p = 0.019), and adverse discharge disposition (OR 1.32 95% CI 1.19-1.46, p < 0.001) compared to white patients. Hispanic patients had increased odds of mortality (OR 1.30 95% CI 1.05-1.60, p = 0.014) and amputation (OR 1.21 95% CI 1.04-1.42, p = 0.016) compared to white patients. Medicare patients had increased odds of mortality (OR 1.35 95% CI 1.09-1.67, p = 0.006), Medicaid patients had increased odd of amputation (OR 1.33 95% CI 1.17-1.51, p < 0.001) and prolonged LOS (OR 1.33 95% CI 1.17-1.51, p < 0.001). Patients in the lower income quartiles had decreased odds of amputation compared to the highest income quartile, including the 26th to 50th income quartile (OR 0.84 95% CI 0.73-0.98, p = 0.022) and 51st to 75th income quartile (OR 0.84 95% CI 0.73-0.98, p = 0.022).Racial and socioeconomic disparities exist for patients being treated for NSTIs.

BACKGROUND: Frequency, microbiology, and outcomes of necrotizing soft tissue infections vary based on locoregional and environmental factors; however, there has been no global survey of these patterns. We performed a systematic review/meta-analysis on published reports of necrotizing soft tissue infections from across the globe. METHODS: Peer-reviewed empirical studies examining rates of polymicrobial and monomicrobial necrotizing soft tissue infections with microbial isolation and overall mortality rate were extracted along with geographic location using PubMed, Scopus, ProQuest, and Web of Science. Random-effects meta-analyses and sensitivity analyses were performed, adjusting for publication bias. Meta-regression analyses examined moderator effects of risk factors. RESULTS: One hundred and five studies (8,718 total patients) were included. Pooled prevalence of polymicrobial and monomicrobial infections were 53% and 37.9%, respectively. Truncal necrotizing soft tissue infections were commonly polymicrobial (P < .001), whereas monomicrobial infections prevailed in extremities (P = .008). Global prevalence of monomicrobial necrotizing soft tissue infections was observed to increase by 1.1% annually (P = .003). Staphylococcus aureus was the most common organism globally and in North America, Asia, the Middle East, and Africa, followed by Streptococcus pyogenes and Escherichia coli. Methicillin-resistant S. aureus accounted for 16% of necrotizing soft tissue infections globally. Overall mortality was 23.1%, observed to decline globally over the last decade (P = .020). No regional differences were noted for mortality. CONCLUSION: Although polymicrobial infections remain predominant worldwide, the incidence of monomicrobial infections is increasing. The observed decline in necrotizing soft tissue infection-related mortality is encouraging and may reflect advances in management, despite major variations in available healthcare resources globally.

Background Prior work has demonstrated inferior outcomes for a multitude of medical and surgical conditions at hospitals with high burdens of underinsured patients (safety-net). The present study aimed to evaluate trends in incidence, clinical outcomes and resource utilization in the surgical management of necrotizing soft-tissue infections (NSTI) at safety-net hospitals. Materials and methods Adults requiring surgical debridement/amputation following NSTI-related hospitalizations were identified in the 2005-2018 National Inpatient Sample. Safety-net status (SNH) was assigned to institutions in the top tertile for annual proportion of underinsured patients. Logistic multivariable regression was utilized to evaluate the association of SNH with mortality, hospitalization duration (LOS), costs and discharge disposition. Results Of an estimated 212,692 patients, 76,719 (36.1%) were managed at SNH. The annual incidence of NSTI admissions increased overall while associated mortality declined. After adjustment, SNH status was associated with greater odds of mortality (adjusted odds ratios: 1.14, 95% CI: 1.03-1.26), LOS (ß: +1.8 d, 95% CI: 1.3-2.2) and costs (ß: +$4,400, 95% CI: 2,900-5,800). SNH patients had similar rates of amputation but lower likelihood of care facility or home health discharge. Conclusion With a rising incidence and overall reduction in mortality, safety-net hospitals persistently exhibit greater mortality and resource use for surgical NSTI admissions. Variation in access, disease presentation and timeliness of operative intervention may explain the observed findings.

BACKGROUND: Necrotizing soft-tissue infections (NSTIs) encompass a group of severe, life-threatening diseases with high morbidity and mortality. Evidence suggests advanced age is associated with worse outcomes. To date, no large data sets exist describing outcomes in older individuals, and risk factor identification is lacking. METHODS: Retrospective data were obtained from the 2015 Medicare 100% sample. Included in the analysis were those aged ≥65 y with a primary diagnosis of an NSTI (gas gangrene, necrotizing fasciitis, cutaneous gangrene, or Fournier's gangrene). Risk factors for in-hospital mortality and discharge disposition were examined. Continuous variables were assessed using central tendency, t-tests, and Wilcoxon rank-sum tests. Categorical variables were assessed using the chi-squared and Fisher's exact tests. Statistical significance was defined as P < 0.05. RESULTS: 1427 patient records were reviewed. 59% of patients were male, and the overall mean age was 75.4±8.6 y. 1385 (97.0%) patients required emergency surgery for their NSTI diagnosis. The overall mortality was 5.3%. Several underlying comorbidities were associated with higher rates of mortality including cancer (OR: 3.50, P = 0.0009), liver disease (OR: 2.97, P = 0.03), and kidney disease (OR: 2.15, P = 0.01). While associated with high in-hospital mortality, these diagnoses were not associated with a difference in the rate of discharge to home compared with skilled nursing or rehab. Overall, patients discharged to skilled nursing facilities or rehab had higher rates of underlying comorbidities than patients who were discharged home (3 or more comorbid illness 84.3% versus 68.6%, P < 0.0001); however, no individual comorbid illness was associated with discharge location. CONCLUSIONS: In our Medicare data set, we identified several medical comorbidities that are associated with increased rates of in-hospital mortality. Patients with underlying cancers had the highest odds of increased mortality. The effect on outcomes of the potentially immunosuppressive cancer treatments in these patients is unknown. These data suggest that patients with underlying illnesses, especially cancer, kidney disease, or liver disease have higher mortalities and are more likely to be discharged to skilled nursing facilities or rehab. It is unclear why these illnesses were associated with these worse outcomes while others including diabetes and heart disease were not. These data suggest that these particular comorbid illnesses may have special prognostic implications, although further analysis is necessary to identify the causative factors.

BACKGROUND: Despite concerns about the burden of the bacterial and fungal infection syndromes related to injection drug use (IDU), robust estimates of the public health burden of these conditions are lacking. The current article reviews and compares data sources and national burden estimates for infective endocarditis (IE) and skin and soft-tissue infections related to IDU in the United States. METHODS: A literature review was conducted for estimates of skin and soft-tissue infection and endocarditis disease burden with related IDU or substance use disorder terms since 2011. A range of the burden is presented, based on different methods of obtaining national projections from available data sources or published data. RESULTS: Estimates using available data suggest the number of hospital admissions for IE related to IDU ranged from 2900 admissions in 2013 to more than 20 000 in 2017. The only source of data available to estimate the annual number of hospitalizations and emergency department visits for skin and soft-tissue infections related to IDU yielded a crude estimate of 98 000 such visits. Including people who are not hospitalized, a crude calculation suggests that 155 000-540 000 skin infections related to IDU occur annually. DISCUSSION: These estimates carry significant limitations. However, regardless of the source or method, the burden of disease appears substantial, with estimates of thousands of episodes of IE among persons with IDU and at least 100 000 persons who inject drugs (PWID) with skin and soft-tissue infections annually in the United States. Given the importance of these types of infections, more robust and reliable estimates are needed to better quantitate the occurrence and understand the impact of interventions.

Increasing access to rapid diagnostic tests for malaria (mRDTs) has raised awareness of the challenges healthcare workers face in managing non-malarial febrile illnesses (NMFIs). We examined NMFI prevalence, clinical diagnoses, and prescribing practices in outpatient clinics across different malaria transmission settings in Malawi. Standardized facility-based malaria surveillance was conducted at three facilities one of every 4 weeks over 2 years. Information on demographics, presenting symptoms, temperature, clinical diagnosis, and treatment were collected from outpatients presenting with malaria-like symptoms. Of the 25,486 patients with fever, 69% had NMFI. Non-malarial febrile illness prevalence was lower in 5- to 15-year-old patients (55%) than in children < 5 years (72%) and adults > 15 years of age (77%). The most common clinical diagnoses among febrile patients with negative mRDTs in all age-groups and settings were respiratory infections (46%), sepsis (29%), gastroenteritis (13%), musculoskeletal pain (9%), and malaria (5%). Antibiotic prescribing was high in all age-groups and settings. Trimethoprim-sulfamethoxazole (40%) and amoxicillin (29%) were the most commonly prescribed antibiotics and were used for nearly all clinical diagnoses. In these settings with minimal access to diagnostic tools, patients with fever and a negative mRDT received a limited number of clinical diagnoses. Many were likely to be inaccurate and were associated with the inappropriate use of the limited range of available antibiotics. Prescription and diagnostic practices for NMFIs in the facilities require research and policy input. Resource-limited malaria-endemic countries urgently need more point-of-care diagnostic tools and evidence-based diagnosis and treatment algorithms to provide effective and cost-efficient care.

BACKGROUND: Previous publications indicated an emerging issue with community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), particularly skin and soft tissue infections (SSTIs), in Indigenous communities in Canada. The objectives of this analysis were to explore the prevalence of SSTIs due to CA-MRSA and patterns of antimicrobial use in the community setting. METHODS: A retrospective chart review was conducted as part of an environmental scan to assess antibiotic prescriptions in 12 First Nations communities across five provinces in Canada including Alberta, Saskatchewan, Manitoba, Ontario, and Québec. Charts were randomly selected from nursing stations and patients who had accessed care in the previous 12 months and were ≥ 18 years were included in the review. Data was collected from September to December, 2013 on antibiotic prescriptions, including SSTIs, clinical symptoms, diagnostic information including presence of CA-MRSA infection, and treatment. RESULTS: A total of 372 charts were reviewed, 60 from Alberta, 70 from Saskatchewan, 120 from Manitoba, 100 from Ontario, and 22 from Québec. Among 372 patients, 224 (60.2%) patients had at least one antibiotic prescription in the previous 12 months and 569 prescriptions were written in total. The prevalence of SSTIs was estimated at 36.8% (137 cases of SSTIs in 372 charts reviewed). In 137 cases of SSTIs, 34 (24.8%) were purulent infections, and 55 (40.2%) were due to CA-MRSA. CONCLUSIONS: This study has identified a high prevalence of antibiotic use and SSTIs due to CA-MRSA in remote and isolated Indigenous communities across Canada. This population is currently hard to reach and under-represented in standard surveillance system and randomized retrospective chart reviews can offer complimentary methodology for monitoring disease burden, treatment and prevention.

OBJECTIVE: To describe the epidemiology, critical care resource use of and outcomes from an intensive care admission for a skin or soft tissue infection in Central Australia. DESIGN: Retrospective database review of prospectively collected data identifying all patients requiring admission for a life-threatening illness related to a skin or soft tissue infection. SETTING: Intensive care unit Alice Springs Hospital. PARTICIPANTS: All patients admitted with a primary diagnosis of skin or soft tissue infection between 2010 and 2016. MAIN OUTCOME MEASURE: Annualised incidence of skin or soft tissue infection requiring intensive care. Secondary outcomes examined resource use (length of stay, mechanical ventilation) and a description of the microbiology of skin or soft tissue infection in Central Australia. RESULTS: There were 80 admissions to the intensive care unit over the sampling period, yielding an annualised incidence of 24.2 intensive care unit admissions per 100 000 population. Eighty-five per cent were Indigenous with high rates of co-morbid disease including poorly controlled type 2 diabetes, haemodialysis-dependent chronic kidney disease and co-infection with human T-cell lymphocytic virus. The predominant type of skin or soft tissue infection was abscess, predominantly below the waist. Gram-positive cocci comprised 50% of the organisms cultured, and 20% of organisms were multi-resistant. Mortality was 0% and 1.3% at 28 and 90 days respectively. CONCLUSION: The annualised incidence of skin or soft tissue infection requiring intensive care support in Central Australia is higher than expected. This probably reflects the high burden of chronic disease and poor living conditions. While there is no mortality burden associated with skin or soft tissue infection in Central Australia, there is substantial morbidity. The data from this study adds weight to the call for improved primary health resources for this group.

OBJECTIVES: As obesity rates rise in children, it is likely that the number of hospitalized children with obesity is also increasing. However, characterization of the inpatient population with obesity as a whole has not been reported. We aimed to examine trends in the annual prevalence of obesity in hospitalized children and to identify demographic and clinical characteristics associated with higher obesity prevalence in children who are hospitalized. METHODS: We completed a retrospective cohort analysis of children aged 2 to 19 years admitted to a single tertiary children's hospital system for any reason in 2009-2016. Body mass index was calculated from documented height and weight. Children with obesity were defined by using age- and sex-specific body mass index percentile guidelines established by the Centers for Disease Control and Prevention. Annual obesity prevalence was calculated on the encounter level for service line and All Patients Refined Diagnosis-Related Groups (diagnosis groups). χ2 tests were used to determine statistical differences between groups, and the Cochran-Armitage test of trend was used to describe changes in obesity over time. RESULTS: Of 83 329 children who were hospitalized, 17.0% had obesity, increasing from 16.5% of hospitalizations in 2009-2010 to 17.3% in 2015-2016 (P = .002). Service lines with the highest obesity prevalence included orthopedics (22.1%), infectious disease (20.6%), and neuroscience (18.7%). Diagnosis groups with the highest obesity prevalence included cellulitis (22.5%), tonsil/adenoid procedures (22.0%), and some orthopedic procedures (28.7%). CONCLUSIONS: Some groups of children who were hospitalized experience higher obesity prevalence, including children hospitalized with orthopedic, infectious disease, and neurologic problems. In future research, investigators should target disproportionately affected groups by examining health outcomes, patient safety, and satisfaction issues.

We hypothesize that soft tissue infections (SSIs) related to intravenous drug usage (IVDU) are associated with a more complicated and costly course than those not associated with IVDU. For the period 2005-2018, ICD 9/ICD 10 billing codes were used to identify patients admitted with SSIs and their causes/complications and associated costs. IVDU-related infections were then compared with non-IVDU-related infections. t test was used to compare treatment costs and length of stay. Logistic regression analysis was used to assess the likelihood/risk of specific events in the IVDU versus non-IVDU populations. Of 47,281 patients admitted with SSIs, 1323 were associated with IVDU. IVDU-related patients tended to be younger (36.2 vs 49.3 years, P = 0.001). Both cost and length of stay were significantly greater in the IVDU group ($30,471 vs $16,020, P = 0.001; 5.7days vs 3.7days, P = 0.001). In addition, IVDU admissions were more likely to be associated with chronic blood-borne infections (hepatitis B/C, HIV, P = 0.001) and a significantly greater incidence of secondary infectious complications, including endocarditis (P = 0.001), bacteremia (P = 0.001), and osteomyelitis (P = 0.003). SSI admissions related to IVDU are a unique subgroup of patients. These patients not only have longer and more costly lengths of stay but are also at higher risk for secondary complications such as chronic blood-borne viral illness and secondary bacterial infectious complications, such as bacteremia, endocarditis, and osteomyelitis. Further prospective study of these findings is warranted as we continue to battle the growing problem of IVDU in the United States.

The US burden of acute skin infections is substantial. While Staphylococcus aureus and Streptococcus spp. are the most common causes, gram-negative bacteria and mixed infections can occur in some settings. These mixed infections are more likely to result in inappropriate empiric antibiotic therapy. Important challenges remain in diagnosing and treating acute skin infections.

OBJECTIVE: To determine the frequency of pin tract infection in external fixator tibia and its effects on the definite fracture fixation and bone healing. Methods: The prospective study was conducted at Lady Reading Hospital, Peshawar, Pakistan, from August 2017 to July 2018, and comprised patients regardless of age and gender with open fracture tibia Gustillo-Anderson type II and type IIIA. Pin tract infection was assessed following the application of locally made external fixation of tibia open fractures. Follow-up was done fortnightly till soft tissue healing, removal of external fixator and definite fracture healing. Pin tract infection was classifiedand treated according to the Checketts-Otterburn classification system. SPSS 20 was used for data analysis. Results: Of the 117 patients, 95(81%) were males and 22(19%) were females with an overall mean age of 24.7±9.35 years. Pin tract infection was documented in 28(23.9%) patients. Minor and major pin tract infections were reported in 27(96.4%) and 1(3.5%) patient respectively. Soft tissues healed in 27(96.4%) cases. Conclusion: External fixator for initial stabilisation of open tibial fractures in all patients is recommended..

OBJECTIVE: The aim of this study was to compare the incidence of skin and soft tissue infections (SSTIs) across healthcare settings and analyze direct healthcare expenditures related to SSTIs in 2000 and 2012 in the United States. METHODS: We performed a retrospective, cross-sectional analysis of nationally representative data from the Medical Expenditure Panel Surveys. Population-based incidence rates were examined for all healthcare settings that include inpatient visits, emergency department visits and ambulatory visits for SSTIs. The direct costs of healthcare services utilization were reported. Population-based prescribing rates for each antimicrobial class during ambulatory visits were compared. RESULTS: A total of 2.4 million patients experienced an SSTI in 2000 compared to 3.3 million in 2012 (40% increase). From 2000 to 2012, the incidence of patients with at least one hospital visit for SSTIs increased 22%, ambulatory care visits increased 30%, and emergency department visits increased 40%. The incidence of SSTIs in children and adolescents declined 50% (from 150 to 76 per 10,000 person; RR = 0.51, 95% CI: 0.38-0.67; p<0.001) whereas SSTIs in older adults (> 65 years of age) increased almost 2-fold (from 67 to 130 per 10,000 person; RR = 1.94, 95% CI: 1.44-2.61; p<0.001). The annual incidence of SSTI in adults did not change significantly from 2000 to 2012 (from 84 to 81 per 10,000 person; RR = 0.96, 95% CI: 0.71-1.31; p = 0.41). The total estimated direct healthcare costs of SSTIs increased 3-fold from $4.8 billion in 2000 to $15.0 billion in 2012, largely driven by an 8-fold increase in ambulatory expenditures for SSTIs. Total population-based antimicrobial prescription rates for SSTIs increased 4-fold from 2000 to 2012 (from 59.5 to 250.4 per 10,000 person). CONCLUSIONS: The highest healthcare utilization for SSTI treatment occurred in the ambulatory care setting and also accounted for the largest increase in overall direct expenditures from 2000 to 2012.

BACKGROUND: People with diabetes may be at higher risk for acquiring infections through both glucose-dependent and biologic pathways independent of glycemic control. Our aim was to estimate the association between diabetes and infections occurring in primary care. METHODS: Using the Newfoundland and Labrador Sentinel of the Canadian Primary Care Sentinel Surveillance Network, patients with diabetes ≥18 years between 1 January 2008 and 31 March 2013 were included with at least 1-year of follow-up. We randomly matched each patient with diabetes on the date of study entry with up to 8 controls without diabetes. Primary outcome was the occurrence of ≥1 primary care physician visits for any infectious disease. Secondary outcomes included primary visits for head & neck, respiratory, gastrointestinal, genitourinary, skin and soft tissue, musculoskeletal, and viral infections. Using multivariable conditional logistic regression analysis, we measured the independent association between diabetes and the occurrence of infections. RESULTS: We identified 1779 patients with diabetes who were matched to 11,066 patients without diabetes. Patients with diabetes were older, had a higher prevalence of comorbidities, and were more often referred to specialists. After adjusting for potential confounders, patients with diabetes had an increased risk of any infection compared to patients without diabetes (adjusted odds ratio = 1.21, 95% confidence interval 1.07-1.37). Skin and soft tissue infections had the strongest association, followed by genitourinary, gastrointestinal, and respiratory infections. Diabetes was not associated with head and neck, musculoskeletal, or viral infections. CONCLUSION: Patients with diabetes appear to have an increased risk of certain infections compared to patients without diabetes.

Health care-associated infections in burn patients, from ventilator-associated pneumonia to skin and soft tissue infections, can substantially compromise outcomes, because these complications are associated with longer lengths of stay, increased morbidity and mortality, and greater direct medical costs. Health care-associated infections are largely preventable, through surveillance, education, appropriate hand hygiene, and culture change, especially for device-related infections. Systems-based practice, which allows individuals and clinical microsystems to navigate and improve the macro health care system, may be one of the most powerful skill sets to effect change, permitting a shift in culture toward patient safety and quality improvement.

During the 4-year surveillance period, there were 282,571 incident cases of skin and soft tissue infection (SSTI) among active component U.S. military members diagnosed in inpatient or outpatient settings, corresponding to an overall incidence of 558.2 per 10,000 person-years (p-yrs). An additional 10,904 cases occurred in theater of operations (460.0 per 10,000 p-yrs). Approximately half (49.4%) were classified as "other SSTI" (e.g., folliculitis, impetigo); 45.9% were cellulitis/abscess; 4.6% were carbuncles/furuncles; and 0.1% were erysipelas. Annual incidence rates declined by 46.6% over the surveillance period. In general, higher rates of SSTIs were associated with younger age, recruit trainee status, and junior enlisted rank. During the surveillance period, 238,924 service members were treated for SSTIs in outpatient or inpatient settings, which accounted for 395,361 medical encounters and 19,213 hospital bed days. The history of operational significance of skin infections in the military, the high healthcare costs associated with evaluating and treating skin infections, and the risk of infections by antibiotic-resistant organisms highlight the importance of prevention, early diagnosis, and definitive treatment of skin infections, particularly in high-risk settings such as new recruit/basic training populations.

OBJECTIVES: Skin and soft tissue infections (SSTIs) are among the most common bacterial diseases and represent a significant disease burden. The purpose of this study was to describe the real-world management of patients with SSTIs presenting to the emergency department (ED). METHODS: This is a retrospective cohort study. Adult patients identified with a primary diagnosis of SSTI determined by ICD-9 codes were assessed from index presentation for up to 30 days. Records were reviewed 30 days prior to inclusion to ensure index hospitalization was captured. For recurrent visits, a similar strategy was implemented 30 days afterward. RESULTS: Of 446 encounters screened, 357 were included; 106 (29.7%) were admitted to the hospital and 251 (70.3%) were treated outpatient. Of patients with a Charlson Comorbidity Index (CCI) score two or greater, 60.9% were treated as inpatients, whereas admission rates were 30.1% and 14.1% for patients with a CCI score of one and zero, respectively. Inpatients had an average length of stay (LOS) of 7.3 ± 7.1 days. No difference was detected in overall re-presentation to the facility 22.6% and 28.3% (p > 0.05) or in SSTI related re-presentation 10.4% and 15.1% (p > 0.05) between inpatient and outpatients. The most common gram-positive organisms identified on wound/abscess culture were MSSA (37.1% inpatients) and MRSA (66.7% outpatients). Mean total cost of care was $13,313 for inpatients and $413 for outpatients. CONCLUSION: This analysis identifies opportunities to improve processes of care for SSTIs with the aim of decreasing LOS, reducing readmissions, and ultimately decreasing burden on the healthcare system.

Thirty-two patients affected by SSTIs including DFIs were enrolled between 2013 and 2014. Superficial swab was obtained before and after cleansing with sterile saline, and after ultrasonic debridement; deep tissue biopsy was obtained from ulcer base. Samples were diluted with 1 mL of saline, serial 10-fold dilutions to 10-6 were made and 50 µL of each dilution was plated onto appropriate media. Bacteria were identified by Vitek II system. Microbial load was expressed as CFU/mL. Statistical analysis was performed by χ2. Incidence of Gram positives was higher than Gram negatives (S. aureus and P. aeruginosa being the most frequent); concordance (same bacteria isolated before and after debridement) never exceeded 60%. Ultrasonic debridement significantly reduced bacterial load or even suppressed bacterial growth. While reliability of superficial swab is poor for microbiological diagnosis of SSTIs, swabbing after ultrasonic debridement and biopsy of the ulcer base may be equally reliable.
