Abstract Background: Patients with myelodysplastic syndromes (MDS) are at heightened risk for severe infections, including sepsis, due to underlying cytopenias and immune dysregulation. Hospital-level characteristics, including size and available resources, may influence clinical outcomes in these patients, but data remain limited. This study examines the association between hospital bed size and sepsis-related complications in patients with MDS using a nationally representative dataset. Methods: We conducted a retrospective cohort analysis using the National Inpatient Sample (NIS) from 2016 to 2022, identifying adult hospitalizations with co-diagnoses of MDS and sepsis. Hospitalizations were stratified by hospital bed size: small (n = 15,490), medium (n = 22,815), and large (n = 40,245). Multivariable logistic regression, adjusted for patient demographics, comorbidities, and hospital characteristics, was used to assess associations between hospital bed size and eight clinical outcomes: in-hospital mortality, septic shock, acute renal failure, respiratory failure, encephalopathy, disseminated intravascular coagulation (DIC), Clostridioides difficile infection (CDI), and fungal sepsis. Results: Compared to small hospitals, patients treated at large hospitals had significantly higher odds of in-hospital mortality (OR 1.43, p < 0.001), septic shock (OR 1.25, p < 0.001), acute renal failure (OR 1.10, p < 0.001), encephalopathy (OR 1.11, p = 0.004), DIC (OR 1.48, p = 0.007), and fungal sepsis (OR 2.13, p = 0.028). Medium-sized hospitals were also associated with increased odds of mortality (OR 1.16, p = 0.021) and septic shock (OR 1.13, p = 0.038). No statistically significant differences were found in rates of CDI across hospital sizes. Respiratory failure showed a borderline association in medium hospitals (OR 1.05, p = 0.082) but not in large hospitals. Conclusion: Hospital bed size is independently associated with important variations in sepsis-related outcomes among patients with MDS. Large hospitals demonstrated significantly increased odds of multiple complications and mortality, possibly reflecting referral bias, higher disease acuity, or institutional coding practices. These findings underscore the importance of hospital-level factors in evaluating outcomes and resource planning for high-risk hematologic populations.

Abstract Background: Myelodysplastic syndromes (MDS) are a heterogeneous group of clonal hematopoietic disorders often complicated by infections due to cytopenias. Sepsis is a frequent cause of hospitalization and mortality in MDS patients. Neutropenia, a common feature in MDS, may predispose patients to specific infectious complications, but its impact on sepsis-related outcomes remains poorly characterized. Methods: We conducted a retrospective cohort study using the National Inpatient Sample (NIS) database from 2016 to 2022. Adult hospitalizations with co-diagnoses of MDS and sepsis were identified using ICD-10-CM codes. Patients were stratified based on the presence or absence of neutropenia. Multivariable logistic regression models were used to evaluate the association between neutropenia and specific in-hospital outcomes, including Clostridioides difficile infection, fungal sepsis, and disseminated intravascular coagulation (DIC). Models were adjusted for age, sex, comorbidities, hospital characteristics, and illness severity. Results: A total of 78,549 hospitalizations involving MDS patients with sepsis were identified, including 11,295 (14.4%) with neutropenia. Neutropenic patients had significantly higher odds of C. difficile infection (adjusted odds ratio [aOR] 1.61, 95% CI 1.30–1.99, p < 0.001) and fungal sepsis (aOR 2.08, 95% CI 1.22–3.54, p = 0.007) compared to those without neutropenia. However, neutropenia was not significantly associated with DIC (aOR 0.84, 95% CI 0.59–1.19, p = 0.322). Conclusion: In this large national cohort, neutropenia was associated with a significantly increased risk of C. difficile infection and fungal sepsis among MDS patients hospitalized with sepsis. These findings highlight the need for early recognition and targeted antimicrobial strategies in neutropenic MDS patients. No significant association was observed between neutropenia and DIC. Future studies should explore preventive strategies and risk stratification tools tailored to this high-risk population.

Abstract Background: Myelodysplastic syndromes (MDS) are clonal hematopoietic disorders characterized by ineffective hematopoiesis, cytopenias, and an increased susceptibility to infections. Sepsis remains a common and serious cause of morbidity and mortality in this population. While racial disparities in sepsis-related outcomes have been described in the general population, their presence and magnitude among patients with MDS remain poorly understood. Methods: We performed a retrospective cohort study using the National Inpatient Sample (NIS) from 2016 to 2022 to identify adult hospitalizations with co-diagnoses of MDS and sepsis. Patients were stratified by race into White (reference), Black, Hispanic, Asian, Native American, and Other categories. Multivariable logistic regression models, adjusted for demographics, comorbidities, and hospital characteristics, were used to evaluate associations between race and seven key sepsis-related complications: septic shock, acute renal failure, respiratory failure, encephalopathy, disseminated intravascular coagulation (DIC), Clostridioides difficile infection (CDI), and fungal sepsis. Results: Among 78,549 hospitalizations for MDS with sepsis, significant racial disparities were observed. Asian patients had higher odds of developing septic shock (OR 1.26, 95% CI 1.05–1.50, p = 0.014), and both Black (OR 1.24, 95% CI 1.17–1.31, p < 0.001) and Asian (OR 1.14, 95% CI 1.04–1.24, p = 0.004) patients had increased odds of acute renal failure. Respiratory failure was less likely among Black (OR 0.84, 95% CI 0.79–0.90, p < 0.001) and Hispanic (OR 0.76, 95% CI 0.70–0.82, p < 0.001) patients. Encephalopathy was significantly more common in Black (OR 1.29, 95% CI 1.18–1.41, p < 0.001) and Other (OR 1.20, 95% CI 1.01–1.42, p = 0.042) patients. DIC was more frequent in Asian (OR 2.11, 95% CI 1.37–3.27, p = 0.001) and Hispanic (OR 1.53, 95% CI 1.09–2.14, p = 0.014) patients, with a borderline association in Black patients (OR 1.35, p = 0.082). No statistically significant racial differences were noted for CDI or fungal sepsis, although Asian patients trended toward lower odds of CDI (OR 0.64, p = 0.067), and Native American patients had high but non-significant odds for fungal sepsis (OR 3.03, p = 0.287). Conclusion: Our study highlights significant racial disparities in sepsis-related complications among hospitalized MDS patients. Black and Asian patients were more likely to experience acute renal failure and encephalopathy, while Asian and Hispanic patients had higher odds of developing DIC. Conversely, Black and Hispanic patients had lower risk of respiratory failure. These findings underscore the need for race-conscious approaches in sepsis management for patients with MDS and suggest that tailored interventions may be necessary to ensure equitable outcomes across racial groups.

Abstract Background: Cryoprecipitate is indicated for bleeding patients with hypofibrinogenemia, typically when fibrinogen levels fall below 100–150 mg/dL. Despite established national transfusion guidelines, inappropriate use remains a persistent issue in clinical practice, especially in community hospitals where formal transfusion oversight may be limited. Unnecessary transfusions can expose patients to avoidable risks and contribute to increased healthcare costs. As part of a hospital-wide quality improvement initiative, we conducted a retrospective review of cryoprecipitate use at our institution to assess adherence to transfusion guidelines and identify areas for improvement. Methods: We performed a retrospective review of all cryoprecipitate transfusions at Landmark Medical Center, a 214-bed community hospital in Rhode Island, between January 2021 and June 2025. Transfusion episodes were identified through blood bank records. For each episode, we extracted the number of units ordered and administered, pre-transfusion fibrinogen levels, documented clinical indication in the electronic medical record (EMR), and any product wastage. Each transfusion was assessed based on institutional criteria aligned with national guidelines, which recommend cryoprecipitate only in cases of active bleeding with fibrinogen <100–150 mg/dL. Results: Twenty patients received cryoprecipitate in 23 transfusion episodes involving 32 units. Of these, 28 units were administered and 4 were wasted. The majority of patients were female (65%), and 40% were between ages 61 and 75. Only 10 of 23 episodes (43%) met established transfusion criteria. Nine episodes (39%) were given when fibrinogen levels ranged between 100–200 mg/dL, and two episodes (9%) occurred with levels >200 mg/dL. One transfusion was administered without a documented fibrinogen level. Additionally, 8 episodes (35%) lacked a clearly documented indication in the EMR. Three episodes (13%) involved product wastage, including one with no documentation and another where an order was placed but the unit was not administered. Conclusion: This review revealed that more than half of cryoprecipitate transfusions did not meet guideline-based criteria. The findings point to deficiencies in provider knowledge, inconsistent documentation, and limited transfusion oversight contributing to inappropriate use. These results highlight the need for targeted interventions, including: (1) provider education on transfusion thresholds, (2) EMR-based decision support requiring lab values prior to ordering, and (3) routine audits with feedback. Strengthening transfusion practices through structured quality improvement efforts can reduce unnecessary use, improve patient safety, and preserve limited blood product supplies for those who truly need them.
