Healthcare disparities and pelvic organ prolapse operative complications: a nationwide analysis.

INTRODUCTION AND HYPOTHESIS: The objective of this study was to evaluate the differences in the incidence of peri-operative complications at the time of pelvic organ prolapse (POP) repair based on health care disparities such as race and socioeconomic status. METHODS: The National Inpatient Sample (NIS) database was queried using ICD-9/-10 codes for patients aged >18 years undergoing POP repair in 2008-2018. Demographic information, Elixhauser Comorbidity Index (ECI), insurance status, and peri-operative complications were extracted. Multivariate weighted logistic regression using the discharge weights from NIS were constructed on binary outcomes. Complications with at least 1% incidence were included in the analysis. RESULTS: A total of 172,483 POP repair patients were analyzed: 130,022 (75.4%) were white, 10,561 (6.1%) were Black, 21,915 (12.7%) were Hispanic, and 9,985 (5.8%) were of other races. Patients with Medicaid as well as Black, Hispanic, and other races had higher odds of developing postoperative complications such as urinary tract infections, sepsis, and acute renal failure (p value <0.001-0.02). These were also more common in smaller, rural hospitals and with patients with an annual income of $45,999 or less (p value <0.001-0.03). Black and Hispanic patients had lower odds of intraoperative complications such as hemorrhage (aOR 0.77, 95% CI 0.71-0.84; aOR 0.75, 95% CI 0.7-0.8 respectively) or abdominopelvic injury (aOR 0.86, 95% CI 0.81-0.92; aOR 0.93, 95% CI 0.79-0.88 respectively) compared with white patients. CONCLUSION: Nonwhite patients with lower socioeconomic status had increased postoperative complications and fewer intraoperative complications from POP surgery, whereas white patients with higher socioeconomic status had more intraoperative complications.

Long-Term Disability Outcomes for Patients With Ischemic Stroke Presenting With Visual Deficits.

BACKGROUND: Ischemic strokes in both the anterior and posterior circulation can lead to visual deficits, which can affect functional ability. Thrombolytic therapies are often withheld to patients with visual deficits because of either being missed on initial evaluation or because of the misconception that their deficits are not as severe or as disabling. Alternatively, delays in patient arrival for emergent evaluation lead to missed opportunities for acute stroke treatment. This retrospective study aims to explore the differences in perceived long-term disability for patients with stroke who present with visual deficits vs those who do not as a manifestation of their acute stroke syndrome. In addition, we explore the differences in treatment effect with thrombolytics and further analyze if the region of ischemia causing the deficit leads to differences in disability outcomes. METHODS: We conducted a retrospective analysis of patients with visual deficits as evidenced by an abnormal score on NIHSS categories related to vision (gaze palsy, visual fields, or extinction/inattention). Patients with Acute Ischemic Stroke were reviewed from the Houston Methodist Hospital Outcomes-based Prospective Endpoints in Stroke (HOPES) Registry from 2016-2021 for visual deficits. In total, 155 patient charts with visual deficits and 155 patient charts without a documented visual deficit were reviewed for ischemic stroke location (anterior vs posterior circulation), NIHSS scores, and thrombolytic therapies. The outcome variable was categorized using mRS, as mRS between 0 and 3 while mRS 4 to 6 was considered as poor functional outcome at 90 days. The independent variable was the vision group. A multivariable logistic regression model was constructed adjusting for demographics and comorbidities on the binary outcome. RESULTS: Multivariable logistic model after adjusting for demographics and comorbidities showed that patients with acute ischemic stroke with vision defects were 4 times more likely to have poor functional outcomes at 90 days, with most of these patients (14% vs 6%; P < 0.05) suffering from severe disability compared with patients in the control group (i.e., patients with acute ischemic stroke without vision defects) (OR = 4.05; 95% CI [2.28-7.19]; P < 0.001). The application of thrombolytics and the location of ischemia (ACS vs PCS) did not result in a significant change in disability outcomes in patients with visual defects in this limited sample size. CONCLUSIONS: The results of this study indicated that a large population of patients with ischemic stroke experience visual deficits and are, therefore, at an increased likelihood of worse functional outcome. This reveals the necessity for rehabilitation techniques that specifically target visual deficits to speed up the recovery process of these patients. Further studies with larger sample size are needed to assess whether the location of ischemic event and the application of thrombolytic treatments plays a role in the disability outcomes of these patients.

Quantifying Occupational Stress in Intensive Care Unit Nurses: An Applied Naturalistic Study of Correlations Among Stress, Heart Rate, Electrodermal Activity, and Skin Temperature.

OBJECTIVE: To identify physiological correlates to stress in intensive care unit nurses. BACKGROUND: Most research on stress correlates are done in laboratory environments; naturalistic investigation of stress remains a general gap. METHOD: Electrodermal activity, heart rate, and skin temperatures were recorded continuously for 12-hr nursing shifts (23 participants) using a wrist-worn wearable technology (Empatica E4). RESULTS: Positive correlations included stress and heart rate (ρ = .35, p < .001), stress and skin temperature (ρ = .49, p < .05), and heart rate and skin temperatures (ρ = .54, p = .0008). DISCUSSION: The presence and direction of some correlations found in this study differ from those anticipated from prior literature, illustrating the importance of complementing laboratory research with naturalistic studies. Further work is warranted to recognize nursing activities associated with a high level of stress and the underlying reasons associated with changes in physiological responses. APPLICATION: Heart rate and skin temperature may be used for real-time detection of stress, but more work is needed to validate such surrogate measures.

Sepsis outcomes in solid organ transplant recipients.

BACKGROUND: We present data on a cohort of patients diagnosed with sepsis over a 10-year period comparing outcomes in solid organ transplant (SOT) and non-solid organ transplant (non-SOT) recipients. METHODS: This is a retrospective single-center study of patients with diagnosis of sepsis from 1/1/06 to 6/30/16. Cases and controls were matched by year of sepsis diagnosis with propensity score matching. Conditional logistic regression and repeated measurement models were performed for binary outcomes. Trends over time for in-hospital mortality were determined using the Cochran-Armitage test. A gamma-distributed model was performed on the continuous variables. RESULTS: Overall, there were 18 632 admission encounters with a discharge diagnosis of sepsis in 14 780 unique patients. Of those admissions, 1689 were SOT recipients. After 1:1 matching by year, there were three thousand three hundred and forty patients (1670 cases; 1670 controls) diagnosed with sepsis. There was a decreasing trend for in-hospital mortality for sepsis over time in SOT patients and non-SOT patients (P < .05) due to early sepsis recognition and improved standard of care. Despite higher comorbidities in the SOT group, conditional logistic regression showed that in-hospital mortality for sepsis in SOT patients was similar compared with non-SOT patients (odds ratio [OR] =1.14 [95% confidence interval {CI}, 0.95-1.37], P = .161). However, heart and lung SOT subgroups had higher odds of dying compared with the non-SOT group (OR = 1.83 [95% CI, 1.30-2.57], P < .001 and OR = 1.77 [95% CI, 1.34-2.34], P < .001). On average, SOT patients had 2 days longer hospital length of stay compared with non-SOT admissions (17.00 ± 19.54 vs 15.23 ± 17.07, P < .05). Additionally, SOT patients had higher odds of hospital readmission within 30 days (OR = 1.25 [95% CI, 1.06-1.51], P = .020), and higher odds for DIC compared with non-SOT patients (OR = 1.76 [95% CI, 1.10-2.86], P = .021). CONCLUSION: Sepsis in solid organ transplants and non-solid organ transplant patients have similar mortality; however, the subset of heart and lung transplant recipients with sepsis has a higher rate of mortality compared with the non-solid organ transplant recipients. SOT with sepsis as a group has a higher hospital readmission rate compared with non-transplant sepsis patients.

Clinical impact of pulmonary arterial hypertension on SARS-CoV-2 outcomes: U.S. pre-vaccination analysis.

Our retrospective study aimed to determine how pulmonary arterial hypertension (PAH) influences the clinical outcomes of COVID-19 admissions by using data from the 2020 nationwide inpatient sample (NIS). Among the 1,018,915 adults who were hospitalized with COVID-19 in 2020, 155 also had a PAH diagnosis. After adjusting for all baseline demographics and co-morbidities through multivariate analysis, we found that in patients admitted with a principal diagnosis of COVID-19, PAH was not associated with an increased risk of mortality compared to those without PAH. (adjusted OR 0.58 [95% CI 0.2-1.6] p=0.3). In addition, patients with both COVID-19 and PAH showed no statistically significant difference in the odds of requiring mechanical ventilation (adjusted OR 1.1 [95% CI 0.5-2.6] p=0.9), vasopressor needs (adjusted OR 0.4 [95% CI 0.1-3.5] p=0.4), acute kidney injury necessitating renal replacement therapy(adjusted OR 0.7 [95% CI 0.3-1.7] p=0.5), mean length of stay (LOS) (11.1 vs. 7.5 days), adjusted difference 3.1 [95% CI -3.8- 10.1] p=0.37) or mean total hospitalization charges ($195,815 vs $79,082, adjusted difference 107,146 [95% CI -93,939 - 308,232] p=0.29). Further studies are needed to investigate this subpopulation during the post-vaccination era to observe the effects of outcomes in these patients.

Pain Related to Intradetrusor BotulinumtoxinA: A Randomized Clinical Trial.

IMPORTANCE: OnabotulinumtoxinA (BTX-A) is an effective treatment for overactive bladder (OAB), but few studies have been done to evaluate injection techniques. OBJECTIVE: The primary objective was to evaluate procedural discomfort between 2 commonly used injection techniques for BTX-A. STUDY DESIGN: This was a single-blinded, randomized clinical trial of women undergoing injection of 100 U BTX-A for idiopathic OAB. Patients were randomized to 5 mL/5 injection or 10 mL/10 injection groups. Bladder pain was assessed by a validated Numeric Pain Rating Scale. Overactive bladder symptoms were assessed with a standardized questionnaire (Overactive Bladder Questionnaire Short Form). Patient satisfaction, treatment efficacy, and adverse events were assessed at 30 days after procedure. RESULTS: One hundred eight patients were randomized to 52 in the 5 mL/5 injection arm and 56 in the 10 mL/10 injection arm. Mean procedural pain scores were 3.2 (±2.3) in the 5 mL/5 injection group versus 3.6 (±2.1) in the 10 mL/10 injection group (P = 0.21). No difference was found when categorizing pain scores into ordinal outcomes of low (P = 0.55), medium (P = 0.70), and high (P = 1.0) or a binary outcome of low (P = 0.55) versus medium + high (P = 0.55). Multivariate analyses did not effect statistical significance between the 2 groups for the ordinal outcome (odds ratio = 1.86; 95% confidence interval = 0.77 = 4.52; P = 0.17) or the binary outcome (odds ratio = 1.81; 95% confidence interval = 0.68-4.77; P = 0.28). No difference was observed between overall patient satisfaction, global impression of improvement, Overactive Bladder Questionnaire Short Form scores, or adverse outcomes. CONCLUSIONS: Procedural discomfort related to BTX-A injection for idiopathic OAB was not different between 2 injection protocols. Overall satisfaction was high for both groups, and there was no difference in symptom scores or adverse events.

Investigating patient engagement associations between a postdischarge texting programme and patient experience, readmission and revisit rates outcomes.

OBJECTIVES: This study aimed (1) to examine the association between patient engagement with a bidirectional, semiautomated postdischarge texting programme and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey outcomes, readmissions and revisit rates in a large health system and (2) to describe operational and clinical flow considerations for implementing a postdischarge texting programme. SETTING: The study involved 1 main academic hospital (beds: 2500+) and 6 community hospitals (beds: 190-400, averaging 300 beds per hospital) in Houston, Texas. METHODS: Retrospective, observational cohort study between non-engaged patients (responded with 0-2 incoming text messages) and engaged patients (responded with 3+ incoming, patient-initiated text messages) between December 2022 and May 2023. We used the two-tailed t-test for continuous variables and χ2 test for categorical variables to compare the baseline characteristics between the two cohorts. For the binary outcomes, such as the revisit (1=yes, vs 0=no) and readmissions (1=yes vs 0=no), we constructed mixed effect logistic regression models with the random effects to account for repeated measurements from the hospitals. For the continuous outcome, such as the case mix index (CMI), a generalised linear quantile mixed effect model was built. All tests for significance were two tailed, using an alpha level of 0.05, and 95% CIs were provided. Significance tests were performed to evaluate the CMI and readmissions and revisit rates. RESULTS: From 78 883 patients who were contacted over the course of this pilot implementation, 49 222 (62.4%) responded, with 39 442 (50%) responded with 3+ incoming text messages. The engaged cohort had higher HCAHPS scores in all domains compared with the non-engaged cohort. The engaged cohort used significantly fewer 30-day acute care resources, experiencing 29% fewer overall readmissions and 20% fewer revisit rates (23% less likely to revisit) and were 27% less likely to be readmitted. The results were statistically significant for all but two hospitals. CONCLUSIONS: This study builds on the few postdischarge texting studies, and also builds on the patient engagement literature, finding that patient engagement with postdischarge texting can be associated with fewer acute care resources. To our knowledge, this is the only study that documented an association between a text-based postdischarge programme and HCAHPS scores, perhaps owing to the bidirectionality and ease with which patients could interact with nurses. Future research should explore the texting paradigms to evaluate their associated outcomes in a variety of postdischarge applications.

Occupational stress and burnout among intensive care unit nurses during the pandemic: A prospective longitudinal study of nurses in COVID and non-COVID units.

Background: Intensive care unit (ICU) nurses are highly prone to occupational stress and burnout, affecting their physical and mental health. The occurrence of the pandemic and related events increased nurses' workload and further exacerbated their stress and burnout. This work investigates occupational stress and burnout experienced by ICU nurses working with COVID and non-COVID patients. Method: A prospective longitudinal mixed-methods study was conducted with a cohort of ICU nurses working in medical ICU (COVID unit; n = 14) and cardiovascular ICU (non-COVID unit; n = 5). Each participant was followed for six 12-h shifts. Data on occupational stress and burnout prevalence were collected using validated questionnaires. Physiological indices of stress were collected using wrist-worn wearable technologies. Participants elaborated on the causes of stress experienced each shift by completing open-ended questions. Data were analyzed using statistical and qualitative methods. Results: Participants caring for COVID patients at the COVID unit were 3.71 times more likely to experience stress (p < 0.001) in comparison to non-COVID unit participants. No differences in stress levels were found when the same participants worked with COVID and non-COVID patients at different shifts (p = 0.58) at the COVID unit. The cohorts expressed similar contributors to stress, based in communication tasks, patient acuity, clinical procedures, admission processes, proning, labs, and assisting coworkers. Conclusion: Nurses in COVID units, irrespective of whether they care for a COVID patient, experience occupational stress and burnout.

Clinical Outcomes of Heart Transplant Recipients Admitted with COVID-19 Infection in 2020: A Nationwide Analysis.

The COVID-19 pandemic, caused by infection of the SARS-CoV-2 virus, has impacted morbidity and mortality through widespread cytokine release and aberrant immunity; the mainstay of management has been immunosuppression. The aim of our retrospective study is to determine the effects of solid-organ transplantation (SOT) on COVID-19 admissions using data from the 2020 nationwide inpatient sample (NIS). After multivariate adjustment, we found COVID-19 admission with SOT had no difference in mortality (11.5% vs 11.1%, adjusted OR: 0.99 [95% CI 0.84-1.19, P = 0.99], no difference in need for vasopressor use (2.6% vs 1.8%, adjusted OR: 1.02 [95% CI 0.73-1.44, P = 0.88]), lower odds of requiring mechanical ventilation (MV) (13.7% vs 14.8%, adjusted OR: 0.83 [95% CI 0.71-0.97, P = 0.02]), lower odds of MV within 24 hours of admission (adjusted OR: 0.60 [95% CI 0.47-0.78, P < 0.01]), increased odds of mechanical circulatory support needs (adjusted OR 3.7 [95% CI 1.2-11.7, P = 0.025]), increased odds of acute renal failure requiring renal replacement therapy (adjusted OR 1.66 [95% CI 1.29-2.15, P < 0.01]), decreased mean length of stay (7.45 days vs 7.48 days, adjusted difference: 0.8 days less, P <0.01), and no difference in mean total hospitalization charges ($91,316 vs $79,100, adjusted difference: -$2,667, P = 0.57) compared to COVID-19 admissions without SOT.

Educating Women About Pelvic Floor Disorders During Pregnancy From the First to the "Fourth Trimester": A Randomized Clinical Trial.

IMPORTANCE: Pregnancy and childbirth are risk factors for developing pelvic floor disorders (PFDs), and this continues postpartum ("fourth trimester"). Knowledge of PFDs among women of childbearing age is lacking and presents an opportunity for education. OBJECTIVES: The aim of this study was to compare the increase in knowledge of PFDs in patients who received written handouts versus interactive workshops as measured by the Prolapse and Incontinence Knowledge Questionnaire (PIKQ). STUDY DESIGN: This was a randomized clinical trial of pregnant patients 18 years or older. Patients either received written handouts only or received handouts and attended an interactive workshop. Handouts were created in collaboration with communication specialists focusing on risk factors and prevention strategies. The primary outcome was the change in PIKQ score. Secondary outcomes were Pelvic Floor Distress Inventory score and postpartum phone interviews of workshop group participants. Questionnaires were assessed at recruitment and 6 weeks postpartum. The nonparametric Wilcoxon test compared continuous variables, and the Fisher exact test compared categorical variables. RESULTS: One hundred twenty patients were randomized. Demographics were similar between groups. Median PIKQ score change showed no difference between groups (P = 0.37). Pelvic Floor Distress Inventory-20 scores were similar between groups at baseline (P = 0.78) and postpartum (P = 0.82). Quantile regression showed posteducation PIKQ scores were significantly higher in the workshop (21.00 vs 17.00; P = 0.011) and written (21.00 vs 17.00; P < 0.001) groups. Phone interviews showed consistent themes: (1) greater awareness of PFDs, (2) more likely to discuss PFDs, and (3) relief that PFDs are treatable. Fifty-nine percent of patients preferred learning through workshops compared with the handouts. CONCLUSIONS: Both groups showed improvement in knowledge of PFDs. Well-written, illustrated handouts were effective in increasing patient knowledge of PFDs.

Sex Differences in 90-Day Functional Outcomes for Acute Ischemic Stroke Patients With Obstructive Sleep Apnea.

Background Obstructive sleep apnea (OSA) is characterized by repeated episodes of either full or partial obstruction of the upper airway. OSA is an independent risk factor for acute ischemic stroke (AIS) and a contributor to other key risk factors. OSA may damage endothelial and brain tissues and worsen outcomes following AIS. We aimed to evaluate the impact of sex differences on 90-day functional outcomes following AIS in an OSA population, as measured by the modified Rankin Scale (mRS) score. Methodology We performed a retrospective study of patients with OSA and AIS from the Houston Methodist Hospital Outcomes-Based Prospective Endpoints in Stroke (HOPES) Registry from 2016 to 2022. Patients with charts that noted a diagnosis of OSA before AIS or within the 90 days following AIS were included. A multivariable logistic regression model was constructed adjusting for demographics, first admit National Institutes of Health Stroke Scale (NIHSS), and comorbidities on the binary outcome. The odds ratios (ORs) and 95% confidence intervals (CIs) were reported, providing likelihood estimates of a shift to higher mRS for a given comparison between females (reference category) and males. Statistical significance was defined as two-tailed p-values <0.05 for all tests. Results From the HOPES registry, 291 females and 449 males were found to have OSA. Males had a higher proportion of comorbid conditions such as atrial fibrillation (15% vs. 9%, p = 0.014) and intracranial hemorrhage compared to females (6% vs. 2%, p = 0.020). The multivariate logistic regression model showed that males were at two times higher risk for developing poor functional outcomes at 90 days (OR = 2.35, 95% CI = 1.06-5.19), p < 0.001). Conclusions Males were found to have two times higher risk for developing poor functional outcomes at 90 days. This may be due to more severe oxygen desaturation, increased susceptibility to oxidative stress, and greater frequency of full airway obstruction in males. Greater emphasis on early diagnosis and treatment of OSA may be necessary to reduce the disproportionate incidence of poor functional outcomes, particularly among apneic male stroke survivors.

Operative expectations for Mohs surgery in patients with chronic lymphocytic leukemia: A multicenter retrospective cohort study.

Background: Patients with chronic lymphocytic leukemia (CLL) are immunocompromised and have both a higher incidence of and more aggressive skin cancers, often requiring treatment with Mohs micrographic surgery. Objective: Characterize operative expectations for Mohs surgery in patients with CLL. Methods: Multicenter retrospective cohort study. Results: One hundred fifty-nine tumors from 99 patients with CLL were matched 1:4 with controls. Cases had higher odds for requiring at least 3 stages during Mohs surgery compared to controls (odds ratio = 1.91; 95% CI [1.21-3.02]; P = .01). The mean number of Mohs stages in cases was 1.97 (±0.92) compared with 1.67 (±0.87) in controls (P = .0001). A regression analysis showed that cases had larger postoperative tumor areas (cm2) versus controls (mean = 5.57 vs 4.47; estimate difference Δß = 1.10 cm2; 95% CI [0.18-2.03]; P = .02). In logistic regression, cases were twice as likely to receive a flap repair compared to controls (odds ratio = 2.45; 95% CI [1.58-3.8]). Limitations: Retrospective cohort study and lack of histologic subtyping of tumors. Conclusion: Patients with CLL require more Mohs stages to attain clear surgical margins, have larger postoperative defect areas, and require more advanced repair techniques compared to a control population without CLL. These findings are essential for preoperative planning and patient counseling and further support the use of Mohs surgery in patients with CLL.

Impact of Cold Therapy on Paclitaxel-Induced Peripheral Neuropathy and Quality of Life in Patients With Breast Cancer.

BACKGROUND: Taxane drugs frequently produce peripheral neuropathy (PN). Cold therapy to hands and feet during chemotherapy has been effective in reducing PN. OBJECTIVES: The purpose was to compare the frequency and severity of PN and quality of life in patients with breast cancer receiving cold therapy to their hands and feet versus standard of care during 12 weekly paclitaxel infusions with a follow-up at 16 weeks. METHODS: Forty-eight female participants were consecutively recruited and randomized to treatment versus control groups. This randomized control trial used the Common Terminology Criteria for Adverse Events and the Functional Assessment of Cancer Therapy-Taxane questionnaires to collect data weekly for 12 weeks and at 16 weeks. FINDINGS: A repeated-measures ordinal logistic model and binomial logistic model showed that patients on standard therapy were three times more likely to develop PN, with a progression toward severe PN, when compared to patients who were on cold therapy. There was no effect of treatment on quality of life.

Health Care Disparities in Surgical Management of Pelvic Organ Prolapse: A Contemporary Nationwide Analysis.

OBJECTIVES: Our objective was to compare the rate of native tissue repair (NTR) versus sacrocolpopexy (SCP) and reconstructive (RECON) versus obliterative repair (OBR) for the treatment of pelvic organ prolapse (POP), evaluating for health care disparities based on race, socioeconomic, and geographic factors. METHODS: The National Inpatient Sample database was queried for patients older than 18 years undergoing POP surgery from 2008 to 2018. Baseline demographics, comorbidity index, socioeconomic, and hospital variables were extracted. The weighted t test, Wilcoxon test, and χ2 test were used to compare the rate of (1) NTR versus SCP and (2) RECON vs OBR. Multivariate weighted logistic regression was used to compare while controlling for confounders. Reference groups were White race, Medicare patients, northeast region, small hospital size, and rural location. RESULTS: Of 71,262 patients, 67,382 (94.6%) underwent RECON. Patients undergoing OBR were older and had a higher comorbidity score. Multivariate analysis showed the following: (1) Black, Hispanic, and other races; (2) Medicaid patients; (3) patients at urban teaching hospitals are less likely to receive RECON. Patients in the midwest were more likely to receive RECON. Among 68,401 patients, 23,808 (34.8%), and 44,593 (65.19%) underwent SCP and NTR, respectively. Hysterectomy was more common in the NTR group. Multivariate analysis showed the following:(1) Black, Hispanic, and "other" races; (2) uninsured and Medicaid patients; (3) patients in the midwest, south, and west were at higher odds of receiving NTR. Patients in large and urban hospitals were less likely to undergo NTR. CONCLUSIONS: Racial, socioeconomic, and geographic disparities exist in surgical management for POP warranting further study to seek to eliminate these disparities.

Trends in Hospital Admissions for Systolic and Diastolic Heart Failure in the United States Between 2004 and 2017.

Heart failure (HF) affects 6 million people in the United States and costs $30 billion annually. It is unclear whether improvements in length of stay and mortality over the last few decades hold true for both systolic and diastolic HF. To better assess the epidemiological and economic burden of HF, we assessed the trends in outcomes and costs for both systolic and diastolic HF. We identified hospitalizations for systolic and diastolic HF in the National Inpatient Sample database and evaluated trends over the period from 2004 to 2017, adjusting for demographics and co-morbidities. The proportion of patients admitted with an exacerbation of systolic HF increased from 42% to 63% over the study period. We found an overall decreasing trend between 2004 and 2011 in the length of stay for HF in general with a sharper decrease in diastolic than systolic HF. Inpatient mortality decreased between 2004 and 2007 and stabilized between 2008 and 2016. Systolic HF was associated with higher mortality than diastolic HF. The total inflation-adjusted cost did not change significantly over the study period, with systolic HF costing, on average, $3,036 more than diastolic HF per admission. In conclusion, systolic HF overtook diastolic HF, accounting for most HF hospitalizations in 2008. The higher hospitalization costs for systolic HF relative to diastolic HF may have resulted, in part, from greater use of advanced support devices in patients with systolic HF.

Hospitalization and survival of solid organ transplant recipients with coronavirus disease 2019: A propensity matched cohort study.

BACKGROUND: Solid organ transplant (SOT) recipients are predicted to have worse COVID-19 outcomes due to their compromised immunity. However, this association remains uncertain because published studies have had small sample sizes and variability in chronic comorbidity adjustment. METHODS: In this retrospective cohort study conducted at a multihospital health system, we compared COVID-19 outcomes and survival up to 60 days following hospital admission in SOT recipients taking baseline immunosuppressants versus hospitalized control patients. RESULTS: The study included 4,562 patients who were hospitalized with COVID-19 (108 SOT recipients and 4,454 controls) from 03/2020 to 08/2020. Mortality at 60 days was higher for SOT recipients (17% SOT vs 10% control; unadjusted odds ratio (OR) = 1.74, 95% confidence interval (CI) 1.04-2.91, P = 0.04). We then conducted a 1:5 propensity matched cohort analysis (100 SOT recipients; 500 controls) using age, sex, race, body mass index, hypertension, diabetes, chronic kidney disease, liver disease, admission month, and area deprivation index. Within 28 days of admission, SOT recipients had fewer hospital-free days (median; 17 SOT vs 21 control; OR = 0.64, 95%CI 0.46-0.90, P = 0.01) but had similar ICU-free days (OR = 1.20, 95%CI 0.72-2.00, P = 0.49) and ventilator-free days (OR = 0.91, 95%CI 0.53-1.57, P = 0.75). There was no statistically significant difference in 28-day mortality (9% SOT vs 12% control; OR = 0.76, 95%CI 0.36-1.57, P = 0.46) or 60-day mortality (16% SOT vs 14% control; OR = 1.15, 95%CI 0.64-2.08, P = 0.64). CONCLUSIONS: Hospitalized SOT recipients appear to need additional days of hospital care but can achieve short-term mortality outcomes from COVID-19 that are similar to non-SOT recipients in a propensity matched cohort study.

Characteristics and Outcomes of Left Ventricular-Assist Device-Associated Cerebrovascular Events in Setting of Infectious Intracranial Aneurysms.

BACKGROUND AND PURPOSE: The study aims to identify the characteristics and neurological outcomes of the left ventricular-assist device (LVAD)-associated cerebrovascular events (CVE) and infections, particularly in the setting of infectious intracranial aneurysms (IIA). METHODS: A single-center retrospective review of patients having undergone LVAD implantation between 2011 and 2017 was conducted using institutional registries and screened for CVE. Patients with CVE were assessed for concurrent bacteremia; neurovascular imaging was then used to isolate patients with IIA. A review of comorbidities, imaging characteristics, and management were performed to determine predictors of neurological outcomes, as defined by the 90-day modified Rankin scale (mRS) scores. RESULTS: Of the 383 HeartMate II LVAD implantations performed, 43 all-cause stroke events were identified across 35 (9%) patients. The majority of the events were hemorrhagic CVE (n=28) with 21 events complicated by bacteremia. Of patients with hemorrhagic CVE and bacteremia, Staphylococcus aureus (n=10) and Pseudomonas aeruginosa (n= 8) infection were the most frequently associated organisms. Severe disability or death (90-day mRS > 4) was observed in 15 patients (63%). Seven patients had confirmed findings of IIA on diagnostic cerebral angiogram and were associated with distal middle cerebral artery (MCA) territory involvement (n=6; 86%) with concurrent Staphylococcus (n=5, 71%) and/or Pseudomonas (n=4, 57%) infections. Overall, a higher incidence of acute and chronic bacteremia was observed in the hemorrhagic CVE subgroup compared to the ischemic CVE subgroup (74% vs 36% & 71% vs 29%, respectively; p <0.05). Despite endovascular and/or surgical intervention in patients with IIA, four patients failed management and elected for comfort measures. CONCLUSION: Our results indicate that P. aeruginosa and S. aureus bacteremia are associated with a greater incidence of intracranial hemorrhage and worse neurological outcomes. Future management considerations may include pre-implantation cerebrovascular imaging to assess vascular pathology including prior aneurysms and intracranial atherosclerotic disease burden as a screen for higher-risk patients, as well as more aggressive antibiotic therapy at bacteremia onset.

Carboxyhemoglobinemia in Critically Ill Coronavirus Disease 2019 Patients.

Carboxyhemoglobinemia is a common but a serious disorder, defined as an increase in carboxyhemoglobin level. Unfortunately, there are few data on carboxyhemoglobinemia in coronavirus disease 2019 (COVID-19) patients. Therefore, our study aimed to evaluate the incidence and etiologies of carboxyhemoglobinemia in COVID-19 patients and determine any association between carboxyhemoglobinemia and novel coronavirus infection. A retrospective chart review was performed at an academic medical center for all inpatient COVID-19 cases with either single or serial carboxyhemoglobin (COHb) levels from March 2020 through August 2020.Our study demonstrates that carboxyhemoglobinemia in COVID-19 patients is due to sepsis, hemolysis, and cytokine storm, triggered by the novel coronavirus infection sequela and is not directly from the virulence of novel coronavirus. Given the coexisting illnesses in critically ill COVID-19 patients, it is impossible to establish if coronavirus virulence was the culprit of elevated COHb levels. Moreover, our study found a high incidence of carboxyhemoglobinemia in critically ill COVID-19 patients. The oxygen saturation measured by pulse oximetry can be inaccurate and unreliable; however, our study could not demonstrate any uniform results on the discrepancy between oxygen saturation measured by pulse oximetry and arterial blood gas. In this study, COHb levels were measured using a CO-oximeter. Therefore, we recommend monitoring the COHb level routinely in critically ill COVID-19 patients to allow more effective and prompt treatment.

Trends in post-heart transplant biopsies for graft rejection versus nonrejection.

With alternatives such as gene profiling available for surveillance after orthotopic heart transplantation, we sought to evaluate the utilization of endomyocardial biopsies (EMBs) for hospitalized patients after heart transplantation. Surveillance EMBs in patients with and without complications were evaluated from the 2004 to 2014 National Inpatient Sample. Over the study period, there was no significant change in the number of EMB procedures performed (P = 0.44). Of 37,955 EMBs, 2283 (6%) were in the setting of graft complications, while 35,672 EMBs were not related to graft complications. EMBs in graft complications did not show a significant increase in length of stay over time (P = 0.06), but had a significant increase in cost over time (P = 0.001). However, those with graft complications had an average of a 5-day longer length of stay (P < 0.001) and costs that were $88,816 (P < 0.001) more expensive compared with those without graft complications. In conclusion, the vast majority of in-hospital EMBs were not related to heart transplantation complications. Nevertheless, EMB hospitalizations with graft complications showed significantly greater length of stay and cost. With the COVID-19 pandemic, it seems more effective to use minimal-contact health surveillance methods rather than invasive EMBs.
