Emerging trends in nationwide mortality, limb loss, and resource utilization for critical limb ischemia in young adults

BACKGROUND/OBJECTIVES

Recent trends indicate a rise in the incidence of critical limb ischemia (CLI) among younger adults. This study examines trends in CLI hospitalization and outcomes among young adults with peripheral arterial disease (PAD) in the United States.

METHODS

Adult hospitalizations (18-40 years) for PAD/CLI were analyzed from the 2016-2020 nationwide inpatient sample database using ICD-10 codes. Rates were reported per 1000 PAD or 100,000 cardiovascular disease admissions. Outcomes included trends in mortality, major amputations, revascularization, length of hospital stay (LOS), and hospital costs (THC). We used the Jonckheere-Terpstra tests for trend analysis and adjusted costs to the 2020 dollar using the consumer price index.

RESULTS

Approximately 63,045 PAD and 20,455 CLI admissions were analyzed. The mean age of the CLI cohort was 32.7 ± 3 years. The majority (12,907; 63.1 %) were female and white (11,843; 57.9 %). Annual CLI rates showed an uptrend with 3265 hospitalizations (227 per 1000 PAD hospitalizations, 22.7 %) in 2016 to 4474 (252 per 1000 PAD hospitalizations, 25.2 %) in 2020 (Ptrend<0.001), along with an increase in PAD admissions from 14,405 (188 per 100,000, 0.19 %) in 2016 to 17,745 (232 per 100,000, 0.23 %%) in 2020 (Ptrend<0.0001). Annual in-hospital mortality increased from 570 (2.8 %) in 2016 to 803 (3.9 %) in 2020 (Ptrend = 0.001) while amputations increased from 1084 (33.2 %) in 2016 to 1995 (44.6 %) in 2020 (Ptrend<0.001). Mean LOS increased from 5.1 (SD 2.7) days in 2016 to 6.5 (SD 0.9) days in 2020 (Ptrend = 0.002). The mean THC for CLI increased from $50,873 to $69,262 in 2020 (Ptrend<0.001). The endovascular revascularization rates decreased from 11.5 % (525 cases) in 2016 to 10.7 % (635 cases) in 2020 (Ptrend = 0.025). Surgical revascularization rates also increased from 4.9 % (225 cases) in 2016 to 10.4 % (600 cases) in 2020 (Ptrend = 0.041).

CONCLUSION

Hospitalization and outcomes for CLI worsened among young adults during the study period. There is an urgent need to enhance surveillance for risk factors of PAD in this age group.

Co-occurrence of bipolar disorder and personality disorders in the United States: Prevalence, suicidality, and the impact of substance abuse

BACKGROUND

This study investigates prevalence rates of specific personality disorders (PDs) in individuals with bipolar disorder (BD) and their impact on substance abuse and suicidality, addressing existing gaps in the literature.

METHODS

Using Nationwide Inpatient Sample data (2016-2020), adult hospitalizations for BD with coexisting PDs were analyzed. Study variables were defined using ICD-10-CM codes. Prevalence of PD were reported as cases per 100,000 BD admissions. Regression models assessed the association between substance abuse and suicidality.

RESULTS

About 993,000 admissions for BD were analyzed. The cohort was predominantly Caucasian (70.5 %) with higher female representation (54.5 %). The mean age was 41 years. 89.4 % of individuals had a Charlson Comorbidity Index score ≤ 1. The most common diagnostic subtype was manic episode of BD with or without psychotic features (32.3 %). Coexisting PDs were observed in 12.2 % of the population, with borderline PD (8.2 %) and antisocial PD (2.6 %) being most prevalent. Substance abuse was common (44.8 %), with cannabis (23.8 %), alcohol (19.4 %), cocaine (10.5 %), and opioids (9.6 %) being most reported. Substance abuse was higher in individuals with BD and PD (50 %) compared to BD alone (44.1 %). 596 suicide attempts were recorded (60 per 100,000 BD admissions). Substance abuse and coexisting PD in bipolar individuals elevated the likelihood of attempts (P < 0.001).

LIMITATIONS

Use of administrative data (retrospective, inpatient); treatment not studied.

CONCLUSION

The study reveals a notable prevalence of PDs in individuals with BD, with increased likelihood of substance abuse and suicide attempts in those with coexisting BD and PD compared to BD alone.

Cardiovascular Event Predictors in Hospitalized Chronic Kidney Disease (CKD) Patients: A Nationwide Inpatient Sample Analysis

INTRODUCTION

This study seeks to confirm the risk factors linked to cardiovascular (CV) events in chronic kidney disease (CKD), which have been identified as CKD-related. We aim to achieve this using a larger, more diverse, and nationally representative dataset, contrasting with previous research conducted on smaller patient cohorts.

METHODS

 The study utilized the nationwide inpatient sample database to identify adult hospitalizations for CKD from 2016 to 2020, employing validated ICD-10-CM/PCS codes. A comprehensive literature review was conducted to identify both traditional and CKD-specific risk factors associated with CV events. Risk factors and CV events were defined using a combination of ICD-10-CM/PCS codes and statistical commands. Only risk factors with specific ICD-10 codes and hospitalizations with complete data were included in the study. CV events of interest included cardiac arrhythmias, sudden cardiac death, acute heart failure, and acute coronary syndromes. Univariate and multivariate regression models were employed to evaluate the association between CKD-specific risk factors and CV events while adjusting for the impact of traditional CV risk factors such as old age, hypertension, diabetes, hypercholesterolemia, inactivity, and smoking.

RESULTS

 A total of 690,375 hospitalizations for CKD were included in the analysis. The study population was predominantly male (375,564, 54.4%) and mostly hospitalized at urban teaching hospitals (512,258, 74.2%). The mean age of the study population was 61 years (SD 0.1), and 86.7% (598,555) had a Charlson comorbidity index (CCI) of 3 or more. At least one traditional risk factor for CV events was present in 84.1% of all CKD hospitalizations (580,605), while 65.4% (451,505) included at least one CKD-specific risk factor for CV events. The incidence of CV events in the study was as follows: acute coronary syndromes (41,422; 6%), sudden cardiac death (13,807; 2%), heart failure (404,560; 58.6%), and cardiac arrhythmias (124,267; 18%). A total of 91.7% (113,912) of all cardiac arrhythmias were atrial fibrillations. Significant odds of CV events on multivariate analyses included: malnutrition (aOR: 1.09; 95% CI: 1.06-1.13; p<0.001), post-dialytic hypotension (aOR: 1.34; 95% CI: 1.26-1.42; p<0.001), thrombophilia (aOR: 1.46; 95% CI: 1.29-1.65; p<0.001), sleep disorder (aOR: 1.17; 95% CI: 1.09-1.25; p<0.001), and post-renal transplant immunosuppressive therapy (aOR: 1.39; 95% CI: 1.26-1.53; p<0.001).

CONCLUSION

The study confirmed the predictive reliability of malnutrition, post-dialytic hypotension, thrombophilia, sleep disorders, and post-renal transplant immunosuppressive therapy, highlighting their association with increased risk for CV events in CKD patients. No significant association was observed between uremic syndrome, hyperhomocysteinemia, hyperuricemia, hypertriglyceridemia, leptin levels, carnitine deficiency, anemia, and the odds of experiencing CV events.

Impact of Obesity on Outcomes of Emergency Department Visits for Cardiac Chest Pain: Insights From a Nationwide Emergency Department Study

Background Obesity, a widespread national epidemic that impacts one in three U.S. adults, is closely linked with the development and exacerbation of cardiovascular disease. The objective of this study was to assess and contrast the outcomes of adults, both obese and non-obese, who present with cardiac chest pain in the emergency department (ED). Methodology A retrospective analysis of the 2020 Nationwide Emergency Department Sample database was conducted. Multivariate regression models were utilized to examine the association between obesity and mortality, discharge disposition, number of procedures, complications, and hospital costs. Results No significant difference in mortality odds was observed between obese and non-obese patients presenting with cardiac chest pain in the ED (adjusted odds ratio (aOR) = 0.92; 95% confidence interval (CI) = 0.59-1.46; p = 0.736). However, obesity was found to be associated with a decreased likelihood of being discharged home from the ED (aOR = 0.57; 95% CI = 0.52-0.63; p < 0.001), as well as an increased likelihood of hospital admission from the ED (aOR = 1.66; 95% CI = 1.53-1.81; p < 0.001). Obesity also correlated with higher odds of non-home discharge (aOR = 1.74; 95% CI = 1.54-1.97; p < 0.001), elevated mean total hospital costs (mean = $13,345 vs. $9,952; mean increase = $3,360; 95% CI = $2,816-$3,904; p < 0.001), and increased risks of cardiac arrests (aOR = 1.52; 95% CI = 1.05-1.88; p < 0.001) and acute respiratory failures (aOR = 1.43; 95% CI = 1.25-1.96; p < 0.001). Obese patients with cardiac pain underwent more procedures on average than non-obese patients (19 vs. 15; aOR = 3.57; 95% CI = 3.04-4.11; p < 0.001). Conclusions Obesity is associated with higher odds of hospital admission from the ED, non-home discharges, higher total hospital costs, and a greater number of procedures.

Impact of frailty on clinical outcomes and resource utilization of hospitalizations for renal stone surgery

PURPOSE

Frailty is reportedly associated with poorer outcomes among surgical patients. Using a coding-based frailty tool, we investigated the impact of frailty on clinical outcomes and resource utilization for urolithiasis hospitalizations.

METHODS

A cohort study using the 2018 National Inpatient Sample database. All adult elective hospitalizations for urolithiasis were included in the study. The study population was categorized into FRAIL and non-frail (nFRAIL) cohorts using the Johns Hopkins Adjusted Clinical Groups frailty clusters. The association between frailty and clinical and financial outcomes was evaluated using multivariate regression models.

RESULTS

About 1028 (14.9%) out of 6900 total hospitalizations were frail. Frailty was not associated with a significant increase in the odds of in-hospital mortality (adjusted odds ratio (aOR) 1.73, 95% CI 0.15-20.02) or length of hospital stay, but was associated with a lower chance of surgery within 24 h of admission (aOR 0.65, 95% CI 0.48-0.90, P = 0.008). A higher Charlson index was independently associated with an over 100% increase in the odds of in-hospital mortality (aOR 2.091, 95% CI 1.53-2.86, P < 0.001). Frail patients paid $15,993 higher in total hospital costs and had a higher likelihood of non-home discharges (aOR 4.29, 95% CI 2.74-6.71, P < 0.001) and peri-operative complications (aOR 1.77, 95% CI 1.14-2.73, P = 0.01).

CONCLUSION

Frailty was correlated with unfavorable outcomes, except mortality and prolonged hospital stay. Incorporating frailty evaluation into risk models has the potential to enhance patient selection and preparation for urolithiasis intervention.

Enteral Nutrition Versus Parenteral Nutrition on Outcomes in Acute Pancreatitis: Insights From the Nationwide Inpatient Sample

INTRODUCTION

Despite considerable research on the comparison of enteral and parenteral nutrition in patients with acute pancreatitis, there is an ongoing debate about the optimal timing of nutrition initiation, invasiveness of interventions, impact on outcomes, and patient tolerance. Given the gap that still exists in the literature, we investigated the relationship between the mode of nutrition and critical outcomes such as mortality rates, inpatient complications, length of hospitalization, and discharge disposition, using comprehensive national-level data. In addition, we investigated the impact of early enteral nutrition on outcomes in acute pancreatitis.

METHODS

All adult discharges for acute pancreatitis between 2016 and 2018 were analyzed from the National (Nationwide) Inpatient Sample (NIS). Discharges of minors and those involving mixed nutrition were excluded from the analysis. Enteral nutrition and parenteral nutrition subgroups were identified using the International Classification of Diseases, 10th revision (ICD-10) codes. Disease severity was defined using the 2013 revised Atlanta Classification of Acute Pancreatitis, along with the All Patient Refined Diagnosis Related Group (APR-DRG)'s severity of illness and likelihood of mortality variables. Complications were identified using ICD-10 codes from the secondary diagnoses variables within the NIS dataset. Multivariable logistic regression analyses were employed to assess associations between the mode of nutrition and the outcomes of interest.

RESULTS

 A total of 379,410 hospitalizations were studied. About 2,011 (0.53%) received enteral nutrition, while 4,174 (1.1%) received parenteral nutrition. The mean age of the study was 51.7 years (SD 0.1). About 2,280 mortalities were recorded in the study. After adjustments, enteral nutrition was associated with significantly lower odds of mortality (adjusted OR (aOR): 0.833; 95%CI: 0.497-0.933; P<0.001). Parenteral nutrition was linked with significantly greater odds of mortality (aOR: 6.957; 95%CI: 4.730-10.233; P<0.001). Both enteral nutrition and parenteral nutrition were associated with augmented odds of complications and prolonged hospitalization (P<0.001) compared to normal oral feeding. Initiation of enteral nutrition within 24 hours of admission did not improve the odds of mortality in this study (aOR: 5.619; 95%CI: 1.900-16.615; P=0.002).

CONCLUSION

 Enteral nutrition demonstrates better outcomes in mortality rates and systemic complications compared to parenteral nutrition in patients unable to maintain normal oral feeding.

Hospital teaching status and patient outcomes in intestinal obstruction surgery: A comparative analysis

Objectives

Surgery at large teaching hospitals is reportedly associated with more favourable outcomes. However, these results are not uniformly consistent across all surgical patients. This study aimed to assess potential disparities in clinical outcomes by hospital type for patients with intestinal obstruction.

Material and Methods

2018 NIS was queried for all adult non-elective admissions for intestinal obstruction. Hospitals were classified as either smallmedium non-teaching hospitals or large teaching hospitals. Multivariate regression analyses were used to assess the association between hospital type and inpatient mortality, access to surgery, admission duration, non-home discharges, hospital costs, and postoperative complications.

Results

After adjustments, admission to large teaching hospitals was not associated with a reduction in inpatient mortality (AOR= 0.73; 95% CI= 0.41- 1.31; p= 0.29), lower likelihood of surgery (AOR= 0.93; 95% CI= 0.58-1.48; p= 0.76) or increased chance of early surgery (p= 0.97). Patients admitted to large teaching hospitals had shorter hospital stays (p= 0.002) and were less likely to be discharged to other acute care hospitals (AOR= 0.94; 95% CI= 0.80-0.94; p= 0.04). Admission to large teaching hospitals was not associated with a reduction in perioperative complications (AOR= 1.04; 95% CI= 0.80- 1.28; p= 0.91) or significantly higher hospital costs (mean increase= 1518; 95% CI= 1891-4927; p= 0.38).

Conclusion

Admission to large teaching hospitals does not necessarily result in better patient outcomes. Merely considering the teaching status of the hospital in isolation cannot explain the diverse outcomes observed for this condition.

The Influence of Insulin Resistance on Outcomes in Hospitalizations for Alcohol-Related Liver Disease: A Nationwide Study

Background Alcoholic liver disease (ALD) is known to contribute to the onset of insulin resistance (IR), which has been speculated to worsen the outcome of the disease. This study examines the impact of IR on the severity and outcomes of hospitalizations for ALD. Methods A retrospective study was performed using the combined 2016 to 2018 Nationwide Inpatient Sample. All admissions for ALD were included. The association between IR and the clinical and resource utilization of hospitalizations for ALD was analyzed using multivariate regression models to adjust for confounding variables. Results About 294,864 hospitalizations for ALD were analyzed. Of these, 383 cases (0.13%) included a secondary diagnosis of IR, while the remaining 294,481 hospitalizations (99.87%) were considered as controls. The incidence of IR in the study was 1.3 per 1000 admissions for ALD. IR was not associated with any significant difference in the likelihood of mortality (adjusted odds ratio (aOR): 1.10, 95% confidence interval (CI): 0.370-3.251, p=0.867), acute liver failure, or the incidence of complications (aOR: 0.83, 95% CI: 0.535-1.274, p<0.001). However, the study found that ALD hospitalizations with IR had longer hospital stays (7.3 days vs. 6.0 days: IRR, 1.17; 95% CI, 1.09-1.26; p<0.001) and higher mean hospital costs ($91,124 vs. $65,290: IRR, 1.32; 95% CI, 1.20-1.46; p<0.001) compared to patients without IR. Conclusion IR alone does not worsen the outcomes of patients with ALD, and its association with longer hospital stays and higher mean hospital costs could be due to other confounding factors.

Gender Disparities in Hospitalization Outcomes and Healthcare Utilization Among Patients with Systemic Lupus Erythematosus in the United States

Background Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease characterized by various clinical manifestations. Despite efforts to improve outcomes, mortality rates remain high, and certain disparities, including gender, may influence prognosis and mortality rates in SLE. This study aims to examine the gender disparities in outcomes of SLE hospitalizations in the US. Methods We conducted a retrospective analysis of the Nationwide Inpatient Sample (NIS) database between 2016 and 2020. The NIS database is the largest publicly available all-payer database for inpatient care in the United States, representing approximately 20% of all hospitalizations nationwide. We selected every other year during the study period and included hospitalizations of adult patients (≥18 years old) with a primary or secondary diagnosis of SLE using International Classification of Diseases, Tenth Revision (ICD-10) codes. The control population consisted of all adult hospitalizations. Multivariate logistic regression was used to estimate the strength of the association between gender and primary and secondary outcomes. The regression models were adjusted for various factors, including age, race, median household income based on patients' zip codes, Charlson comorbidity index score, insurance status, hospital location, region, bed size, and teaching status. To ensure comparability across the years, revised trend weights were applied as the healthcare cost and use project website recommends. Stata version 17 (StataCorp LLC, TX, USA) was used for the statistical analyses, and a two-sided P-value of less than 0.05 was considered statistically significant. Results Among the 42,875 SLE hospitalizations analyzed, women accounted for a significantly higher proportion (86.4%) compared to men (13.6%). The age distribution varied, with the majority of female admissions falling within the 30- to 60-year age range, while most male admissions fell within the 15- to 30-year age category. Racial composition showed a slightly higher percentage of White Americans in the male cohort compared to the female cohort. Notably, more Black females were admitted for SLE compared to Black males. Male SLE patients had a higher burden of comorbidities and were more likely to have Medicare and private insurance, while a higher percentage of women were uninsured. The mortality rate during the index hospitalization was slightly higher for men (1.3%) compared to women (1.1%), but after adjusting for various factors, there was no statistically significant gender disparity in the likelihood of mortality (adjusted odds ratio (aOR): 1.027; 95% confidence interval (CI): 0.570-1.852; P=0.929). Men had longer hospital stays and incurred higher average hospital costs compared to women (mean length of stay (LOS): seven days vs. six days; $79,751 ± $5,954 vs. $70,405 ± $1,618 respectively). Female SLE hospitalizations were associated with a higher likelihood of delirium, psychosis, and seizures while showing lower odds of hematological and renal diseases compared to men. Conclusion While women constitute the majority of SLE hospitalizations, men with SLE tend to have a higher burden of comorbidities and are more likely to have Medicare and private insurance. Additionally, men had longer hospital stays and incurred higher average hospital costs. However, there was no significant gender disparity in the likelihood of mortality after accounting for various factors.

Profile of Childhood Poisoning and Its Outcomes in the United States: A One-Year Nationwide Study of Emergency and Inpatient Admissions

Childhood poisoning is a prevalent and significant public health issue, with a higher incidence among children under the age of five due to their natural inquisitiveness and impulsive behavior. In order to gain a better understanding of the burden and outcomes of acute poisoning in children, this study utilized data from two comprehensive databases: the 2018 Nationwide Emergency Department Sample and the National (Nationwide) Inpatient Sample. A total of 257,312 hospital visits were analyzed, with 85.5% being emergency department visits and 14.5% being inpatient admissions. Drug overdose emerged as the most commonly known cause of poisoning in both emergency and inpatient settings. While alcohol poisoning was the predominantly known cause of non-pharmaceutical poisoning in the inpatient setting, household soaps and detergents were more common in the emergency setting. Among the identified pharmaceutical agents, non-opioid analgesics and antibiotics were the most frequently implicated. However, a significant proportion of the poisoning cases were caused by unidentified substances (26.8% in the pharmaceutical group and 72.2% in the non-pharmaceutical group). There were 211 deaths in total and further analysis revealed that patients with higher Charlson indices and hospital stays exceeding seven days were associated with increased likelihood of mortality. Additionally, admission to teaching hospitals or hospitals located in the western region of the country was linked to an increased likelihood of an extended hospital stay.

Impact of Geriatric Events on Clinical Outcomes and Resource Utilization of Acute Coronary Syndrome Hospitalizations

Background The effect of geriatric events (GEs) on outcomes of acute coronary syndrome (ACS) admissions is poorly understood. We evaluated the prevalence and impact of GEs on clinical outcomes and resource utilization of older patients admitted with ACS. Methods Using the 2018 National (Nationwide) Inpatient Sample, we analyzed all elective hospitalizations for ACS in older adults (age ≥ 65 years) and a younger reference group (age 55-64). Nationally-weighted descriptive statistics were generated for GEs based on ACS subtypes. Multivariate logistic regression models controlling for comorbidities, frailty, patient procedure, and hospital-level variables were used to estimate the association of age with GEs and GEs with outcomes. Results Out of 403,760 admissions analyzed, 71.9% occurred in older adults (≥65 years). The overall rate of any GE in older adults with ACS was 3.4%. With advancing age, the number of GEs was found to significantly increase (p<0.001). After adjustments, having any GE was found to have a significant impact on mortality (adjusted OR (AOR): 1.32; 95%CI: 1.15-1.54; p < 0.001), post-myocardial infarction (MI) complications (AOR: 1.53; 95%CI: 1.36-1.71; p < 0.001), prolonged hospital stays (AOR: 2.97; 95%CI: 2.56-3.30; p < 0.001), and non-home (acute care and skilled nursing home) discharge (AOR: 1.68; 95%CI: 1.53-1.85; p < 0.001). The occurrence of GEs was also associated with a substantial increase in total hospitalization costs with a mean increase of $48,325.22 ± $5,539 (p < 0.001). A dose-response relationship was established between GEs and all outcomes. Limitations of the study included the use of retrospective data and an administrative database. Conclusion Geriatric events were found to significantly worsen outcomes for older adults with ACS. There is, therefore, a need for increased awareness and effective management of GEs in older adults to improve their health outcomes and reduce the burden on the healthcare system.

Systemic lupus erythematous readmissions have reduced: a 9-year longitudinal study of the nationwide readmission database

BACKGROUND

Longitudinal data on the trends in systemic lupus erythematous (SLE) readmissions are limited. We aimed to study trends in 30-day readmissions of patients admitted for SLE flares and all SLE hospitalizations in the USA from 2010 to 2018.

MATERIALS AND METHODS

Data were obtained from the nationwide readmission database (NRD). We performed a retrospective 9-year longitudinal trend analysis using the 2010-2018 NRD databases. We searched for index hospitalizations of adult patients diagnosed with SLE using the International Classification of Diseases (ICD) codes. Elective and traumatic readmissions were excluded from the study. Multivariable logistic and linear regression analyses were used to calculate the adjusted p value trend for categorical and continuous outcomes, respectively.

RESULTS

The 30-day readmissions following index admissions of all SLE patients and for SLE flares decreased from 15.6% in 2010 to 13.3% in 2018 (adjusted p trend < 0.0001), and 20.3% in 2010 to 17.6% in 2018 (adjusted p trend = 0.009) respectively. Following SLE-flare admissions, hospital length of stay (LOS) decreased from 6.7 to 6 days (adjusted p trend = 0.045), while the proportion with a Charlson comorbidity index (CCI) score ≥ 3 increased from 42.2 to 54.4% (adjusted p trend < 0.0001) during the study period. SLE and its organ involvement, sepsis, and infections were common reasons for 30-day readmissions.

CONCLUSION

About 1 in 5 SLE-flare admissions resulted in a 30-day readmission. The 30-day readmissions following index hospitalization for SLE flares and all SLE hospitalizations have decreased in the last decade. Although the readmission LOS was reduced, the CCI score increased over time. Key Points • The 30-day readmissions following index hospitalization for SLE flares and all SLE hospitalizations have reduced in the last decade although the CCI score increased over time. • SLE, its organ involvement, and infections are common reasons for readmission. • Infection control strategies, optimal management of SLE and its complications, and emphasis on an ideal transition of care are essential in reducing SLE readmissions.

Atypical Burkholderia Cepacia Resistance to Ceftazidime/Avibactam and Co-trimoxazole: A Case of Open Wound Contamination and Persistent Bacteremia

Wound contamination and subsequent colonization by microbes can significantly impair tissue repair and lead to the development of chronic non-healing ulcers. Atypical Burkholderia and Actinomycetes bacterial species are common in cases of soil contamination of open wounds leading to a complex infection that is both difficult to diagnose and treat. Despite much research on the involvement of atypical organisms, including Burkholderia and Actinomycetes, in antibiotic resistance, there is no consensus on the timeline from contamination to infection and on an algorithm for early diagnosis and management. Thus, the ways in which these organisms interact in settings of co-infection and contribute to cross-resistance remains unclear. The generally low index of clinical suspicion for atypical microbial infections and the absence of clear diagnostic protocols have multiple consequences, ranging from excessive reliance on pathology, delayed treatment, expensive and ineffective investigations and treatment, and progressive wound sepsis and morbidity. We are reporting a case of Burkholderia cepacia infection, co-infection with Actinomyces spp., and resistance to ceftazidime/avibactam and co-trimoxazole in a 28-year-old previously healthy farmer following soil contamination of an open wound. This is one of only a few reported cases of Burkholderia resistance to ceftazidime/avibactam and the first reported case ofB. cepacia bacteremia due to peripheral contamination.

Psoriasis Is Associated With an Increased Risk of Hospitalization for Systemic Lupus Erythematosus: Analysis of the National Inpatient Sample Database

BACKGROUND

There is a scarcity of literature on co-existing psoriasis (Ps) and systemic lupus erythematosus (SLE). We used a large national population database to determine if there is any association between Ps and SLE. The primary objective was to compare the odds of being admitted for SLE in patients with Ps compared to those without Ps. The secondary objective was to compare hospital outcomes of patients admitted for SLE with co-existing Ps to those without Ps.

METHODS

Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 Databases. We search for hospitalizations using ICD-10 codes. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders.

RESULTS

There were over 71 million discharges included in the database. A total of 20,630 hospitalizations had SLE as the principal diagnosis. One hundred fifty (0.7%) of these SLE hospitalizations have co-existing Ps. Hospitalizations for SLE with co-existing Ps had similar length of stay (LOS), total hospital charges, need for blood transfusion, odds of having a secondary discharge diagnosis of venous thrombosis or embolism/pulmonary embolus, and acute kidney injury compared to those without Ps. Hospitalizations with a secondary diagnosis of Ps have an adjusted odds ratio (AOR)=2.73 (95% CI 1.86-4.02, P<0.0001) of SLE being the principal reason for hospitalization compared to hospitalizations without Ps.

CONCLUSION

In our study, patients with Ps had almost three times the odds of being admitted for SLE compared to non-Ps patients. However, Ps patients admitted for SLE had similar hospital outcomes compared to non-Ps patients admitted for SLE.
