Impact of ICU saturation on hospital mortality from COVID-19 in a secondary care center in Iztapalapa, Mexico City

Abstract INTRODUCTION: A saturated intensive care unit (ICU) setting and socioeconomic factors such as higher poverty rates have been associated with increased rates of in-hospital mortality of COVID-19 patients. Mexico City has become the national epicenter of the pandemic, with Mexico’s highest death toll. Iztapalapa is the delegation with the highest population density and the most notorious conditions of marginalization in Mexico City. We describe the clinical characteristics and risk factors associated with mortality in 164 patients who received care in a hospital ward setting due to ICU saturation in a hospital in Iztapalapa, Mexico City.MATERIALS AND METHODS: In this retrospective cohort study, data from confirmed COVID-19 patients hospitalized between April 1, 2020 and May 31, 2020 were collected. Patients were categorized into different subgroups: alive vs. deceased and intubated vs. non-intubated for analysis between groups. A p-value <0.05 was considered statistically significant.RESULTS: In this setting, 67% of the patients required mechanical ventilation, and 32.3% needed vasopressor support, with in-hospital mortality of 68.3%. The most common complications during hospitalization were acute kidney injury (36%) and acute respiratory distress syndrome (34.8%). We observed similar factors associated with death as previous studies: male sex, older age, comorbidities, laboratory values indicating increased inflammatory/organ failure markers, and severe disease at admission. Additionally, we found that routine use of intravenous antibiotics was associated with a higher rate of in-hospital mortality (RR 3.45, 95% CI 1.69-7.06, p <0.001).CONCLUSIONS: Patients hospitalized due to COVID-19 in a saturated ICU setting had higher mortality than the rates in other studies reported globally.

Abstract Introduction: Low socioeconomic conditions and hospital saturation have been associated with higher mortality rates in hospitalized patients with COVID-19. Mexico City has become the country’s highest death toll. Iztapalapa is the district with the highest population density and marginalization in Mexico City. Most of the information on COVID-19 in-hospital mortality in Mexico comes from intensive care units or tertiary hospitals without considering the level of income. Data regarding hospital mortality in care centers with low availability of intensive care beds has not been explored.Material and methods: A retrospective cohort study in consecutive patients with COVID-19 hospitalized managed outside the intensive care unit in a secondary care center in Mexico City from April 1st, 2020, to May 31st, 2020. Analysis was performed between subgroups with a p-value <0.05 considered statistically significant.Results: A total of 164 patients were recruited; the median age was 52.5 years (IQR 44 - 64.5), 68% were males, 48.7% were obese, and 59.7% had comorbidities. Among those patients, 67% required mechanical ventilation and 32.3% vasopressor support. In this population, 52 recovered (31.7%) and 112 died (68.3%). The main risk factors associated with death were male sex, age > 50 years, diabetes, severe pneumonia on admission, PORT / PSI > 91, SMART-COP > 5, SCAP score > 10, dyspnea on admission, fever during hospitalization [p <0.05] and the administration of intravenous antibiotics [RR 3.45, 95% CI 1.69-7.06, p <0.001].Conclusion: In this study, we found higher in-hospital mortality compared to previous reports. We suggest that the administration of intravenous antibiotics could impact patient survival for the risk of developing hospital-acquired infections.

Abstract Background Transition from continuous renal replacement therapy (CRRT) to intermittent renal replacement therapy (IRRT) can be associated with intra-dialytic hypotension (IDH) although data to inform the definition of IDH, its incidence and clinical implications, are lacking. We aimed to describe the incidence and factors associated with IDH during the first IRRT session following transition from CRRT and its association with hospital mortality. This was a retrospective single-center cohort study in patients with acute kidney injury for whom at least one CRRT-to-IRRT transition occurred while in intensive care. We assessed associations between multiple candidate definitions of IDH and hospital mortality. We then evaluated the factors associated with IDH. Results We evaluated 231 CRRT-to-IRRT transitions in 213 critically ill patients with AKI. Hospital mortality was 43.7% (n = 93). We defined IDH during the first IRRT session as 1) discontinuation of IRRT for hemodynamic instability; 2) any initiation or increase in vasopressor/inotropic agents or 3) a nadir systolic blood pressure of < 90 mmHg. IDH during the first IRRT session occurred in 50.2% of CRRT-to-IRRT transitions and was independently associated with hospital mortality (adjusted odds ratio [OR]: 2.71; CI 1.51–4.84, p < 0.001). Clinical variables at the time of CRRT discontinuation associated with IDH included vasopressor use, higher cumulative fluid balance, and lower urine output. Conclusions IDH events during CRRT-to-IRRT transition occurred in nearly half of patients and were independently associated with hospital mortality. We identified several characteristics that anticipate the development of IDH following the initiation of IRRT.

Introduction: Early studies from Wuhan, China have reported an association between blood type and outcomes in COVID-19 infected patients. Conflicting reports in literature have investigated the protective role of blood type O against worst outcomes associated with COVID-19 infections. Approximately 50% of Black/African Americans (AA) have blood group O. Our study is the only study to date looking at the association between Black/AA and blood type. We aimed to determine the association between blood type and Black/AA patients hospitalized for COVID-19. Methods: We retrospectively reviewed data on patients with known blood type, who were admitted for COVID-19 at a single center between March and April 2020. We excluded other races in our study because only about 2% of the population was Caucasian and 8% representing other races, representing a small subset of patients under study whereas Black/AA represented about 90% of our hospitalized patients. Patients were stratified into 4 groups based on their ABO blood type. Baseline demographic, clinical characteristics and clinical course of the disease were compared. The primary end point was in-hospital mortality. Secondary endpoints included admission to the intensive care unit (ICU), acute kidney injury requiring hemodialysis and length of stay (LOS). Results: During the study period, a total of 256 patients were reviewed. Distribution of ABO type was as follows; A: (N=65) 25%, B: (N=62) 24%, AB: (N=9) 4%, O: (N=120) 47%. Compared to blood types A, B and O, AB patients were younger (mean; yrs. 63 vs. 63 vs. 62 vs. 43 yrs. p=0.0242). Blood type B patients were more likely to present with nausea, than groups A, AB, and O. (27% vs. 10% vs. 0% vs. 5%; p=0.017). All other characteristics including baseline inflammatory markers were comparable. There was no difference among groups regarding in-hospital mortality (A: 39% B: 29% AB: 33% O: 31% p value: 0.676) or admission to the ICU (A:31% B: 28% AB: 33% O: 34% p value: 0.840). The incidence of acute kidney injury requiring hemodialysis was higher in blood type A patients compared to B, AB, and O. (31% vs. 0% vs. 23% vs. 19%; p=0.046). In hospital LOS was comparable among all groups. Conclusions: In this single center analysis of black/AA patients admitted for COVID-19, there was no association between blood type and in-hospital mortality or admission to ICU. Blood type A patients had a higher propensity of kidney injury, but this did not translate into worse in-hospital survival. Disclosures Cohen: GBT: Speakers Bureau.

Abstract Background The clinical manifestations and factors associated with the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections outside of Wuhan are not clearly understood. Methods All laboratory-confirmed cases with SARS-Cov-2 infection who were hospitalized and monitored in Guangzhou Eighth People’s Hospital were recruited from January 20 to February 10. Results A total of 275 patients were included in this study. The median patient age was 49 years, and 63.6% had exposure to Wuhan. The median virus incubation period was 6 days. Fever (70.5%) and dry cough (56.0%) were the most common symptoms. A decreased albumin level was found in 51.3% of patients, lymphopenia in 33.5%, and pneumonia based on chest computed tomography in 86%. Approximately 16% of patients (n = 45) had severe disease, and there were no deaths. Compared with patients with nonsevere disease, those with severe disease were older, had a higher frequency of coexisting conditions and pneumonia, and had a shorter incubation period (all P < .05). There were no differences between patients who likely contacted the virus in Wuhan and those who had no exposure to Wuhan. Multivariate logistic regression analysis indicated that older age, male sex, and decreased albumin level were independently associated with disease severity. Conclusions Most of the patients infected with SARS-CoV-2 in Guangzhou, China are not severe cases and patients with older age, male, and decreased albumin level were more likely to develop into severe ones.

Post Streptococcal Glomerulonephritis

Aims: To determine the clinical and laboratory profile of children with acute post streptococcal glomerulonephritis (APSGN) admitted into Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto, the outcome, and factors associated with in-hospital mortality. Study Design: A 5- year retrospective study. Place of Study: Emergency Paediatric Unit (EPU) and Paediatric Medical Ward (PMW) of the Department of Paediatrics, UDUTH Sokoto. Methodology: The records of children aged 4 to 14 years with the diagnosis of APSGN were reviewed. Relevant history, physical examination findings, laboratory and radiologic investigation findings were extracted from their case folders and recorded into a proforma sheet. Data was analyzed using SPSS version 23. (IBM SPSS Inc., USA). The level of statistical significance was set at 5%, which is p-value < 0.05. Results: Fifty-four (0.9%) of the 6128 children were managed for APSGN giving a prevalence of 10.8 APSGN cases per 1000 children. Forty-one folders were utilized for the study. There were 21(51.2%) females and 20(48.8%) males, with F:M ratio of 1.1:1. Mean age at presentation was 9.1± 3.1 years. Majority (92.6%) were ≥5 years and mainly 22(53.7%) of low socio-economic status. The main features were body swelling 40(97.6%), fever 25(61.0%), oliguria 24(58.5%), systemic hypertension 37(90.2%), proteinuria 41(100.0%), and haematuria 41(100.0%). Acute kidney injury was the commonest 25(61.0%) complication. Thirty (73.2%) cases were discharged, 5 (12.2%) died, 6(14.6%) left against medical advice. Low social status (0.03), requirement for dialysis (p=0.003), congestive cardiac failure (p=0.01), and pulmonary oedema (p=0.04) were significantly associated with in-hospital mortality. Requirement for dialysis (p=0.005) was the independent predictor of in-hospital mortality. At three months post discharge, 20(48.8%) of the 31 cases had achieved complete resolution of APSGN. Conclusion: APSGN is common in Sokoto and similar in pattern to other reports from Nigeria. The presence of complications at presentation increases the risk of in-hospital mortality.

Background: As of May 15, 2020, the United States has reported the greatest number of coronavirus disease 2019 (COVID-19) cases and deaths globally. Objective: To describe risk factors for severe outcomes among adults hospitalized with COVID-19. Design: Cohort study of patients identified through the Coronavirus Disease 2019-Associated Hospitalization Surveillance Network. Setting: 154 acute care hospitals in 74 counties in 13 states. Patients: 2491 patients hospitalized with laboratory-confirmed COVID-19 during March 1-May 2, 2020. Measurements: Age, sex, race/ethnicity, and underlying medical conditions. Results: Ninety-two percent of patients had at least 1 underlying condition; 32% required intensive care unit (ICU) admission; 19% invasive mechanical ventilation; 15% vasopressors; and 17% died during hospitalization. Independent factors associated with ICU admission included ages 50-64, 65-74, 75-84 and 85+ years versus 18-39 years (adjusted risk ratio (aRR) 1.53, 1.65, 1.84 and 1.43, respectively); male sex (aRR 1.34); obesity (aRR 1.31); immunosuppression (aRR 1.29); and diabetes (aRR 1.13). Independent factors associated with in-hospital mortality included ages 50-64, 65-74, 75-84 and 85+ years versus 18-39 years (aRR 3.11, 5.77, 7.67 and 10.98, respectively); male sex (aRR 1.30); immunosuppression (aRR 1.39); renal disease (aRR 1.33); chronic lung disease (aRR 1.31); cardiovascular disease (aRR 1.28); neurologic disorders (aRR 1.25); and diabetes (aRR 1.19). Race/ethnicity was not associated with either ICU admission or death. Limitation: Data were limited to patients who were discharged or died in-hospital and had complete chart abstractions; patients who were still hospitalized or did not have accessible medical records were excluded. Conclusion: In-hospital mortality for COVID-19 increased markedly with increasing age. These data help to characterize persons at highest risk for severe COVID-19-associated outcomes and define target groups for prevention and treatment strategies.

Abstract Background Hypercarbia increases cerebral blood flow secondary to cerebral vasodilatation, while hypocarbia can lead to vasoconstriction with a subsequent decrease in cerebral blood flow. The aim of this study was to examine CO2 cerebral vasoreactivity in a cohort of premature infants and to identify factors which influence this reactivity. Methods We prospectively studied a cohort of hemodynamically stable premature infants [birth weight (BW) <1500 g and gestational age (GA) ≤34 weeks]. Subjects underwent two studies, one in the first 72 h and the second after 1 week of life. Infants were continuously monitored via a physiology station that included transcutaneous CO2 (tcPCO2) monitor, near-infrared spectroscopy (NIRS), arterial pulse oximetry and heart rate. The total hemoglobin (Hb-T) signal of NIRS was used as an indicator of cerebral blood volume (CBV). Correlation between tcPCO2 and Hb-T was performed in each 1-h period using Pearson’s correlation. Factors affecting the CO2 cerebrovascular reactivity were examined using bivariate and linear regression analyses. Results A total of 3847 1-h epochs were obtained from 140 studies of 72 premature infants. tcPCO2 correlated positively with Hb-T in 42% of epochs. In regression analysis, factors associated with increased percentage of positive correlation epochs were male sex and younger postmenstrual age (PMA; β = 0.176, 0.169 and P-value = 0.036, 0.047 respectively). Factors associated with increased strength of positive correlation were mechanical ventilation and increased average tcPCO2 (β = 0.198, 0.220 and P-value = 0.024, 0.011 respectively). Conclusion Increased prematurity, male sex, mechanical ventilation and hypercarbia are associated with stronger PCO2 cerebrovascular reactivity in premature infants. This association may explain their role in the pathogenesis of brain injury.

ABSTRACTBackgroundUnderstanding determinants of developing severe COVID-19 disease is important as studies show that severe disease is associated with worse outcomes.ObjectiveThe study aimed to assess the determinants of COVID-19 disease severity among COVID-19 patients admitted to Millennium COVID-19 Care Center in Ethiopia.MethodsA cross-sectional study was conducted from June to August 2020 among randomly selected 686 patients. Chi-square test was used to detect the presence of a statistically significant difference in the characteristics of the patients based on disease severity (Mild Vs Moderate Vs Severe), where p-value of <0.05 was considered as having a statistically significant difference. A Multivariable multinomial logistic regression model was used to assess the presence of a significant association between the independent variables and COVID-19 disease severity where Adjusted Odds ratio (AOR), 95% CIs for AOR and P-values were used for testing significance and interpretation of results.ResultsHaving moderate as compared with mild disease was significantly associated with having hypertension (AOR= 2.302, 95% CI= 1.266, 4.184, p-value=0.006), diabetes mellitus (AOR=2.607, 95% CI= 1.307, 5.198, p-value=0.007 for diabetes mellitus), fever (AOR= 6.115, 95% CI= 2.941, 12.716, p-value=0.0001) and headache (AOR= 2.695, 95% CI= 1.392, 5.215, p-value=0.003). Similarly, having severe disease as compared with mild disease was associated with age group (AOR= 4.428, 95% CI= 2.497, 7.853, p-value=0.0001 for 40-59 years and AOR=18.070, 95% CI=9.292, 35.140, p-value=0.0001 for ≥ 60 years), sex (AOR=1.842, 95% CI=1.121, 3.027, p-value=0.016), hypertension (AOR= 1.966, 95% CI= 1.076, 3.593, p-value=0.028), diabetes mellitus (AOR= 3.926, 95% CI= 1.964, 7.847, p-value=0.0001), fever (AOR= 13.218, 95% CI= 6.109, 28.601, p-value=0.0001) and headache (AOR= 4.816, 95% CI= 2.324, 9.979, p-value=0.0001). In addition, determinants of severe disease as compared with moderate disease were found to be age group (AOR= 4.871, 95% CI= 2.854, 8.315, p-value=0.0001 for 40-59 years and AOR= 18.906, 95% CI= 9.838, 36.334, p-value=0.0001 for ≥ 60 years), fever (AOR= 2.161, 95% CI= 1.286, 3.634, p-value=0.004) and headache (AOR= 1.787, 95% CI= 1.028, 3.107, p-value=0.039).ConclusionsBeing old, male sex, hypertension, diabetes mellitus, and having symptoms of fever and headache were found to be determinants of developing a more severe COVID-19 disease category. We recommend a better preventive practice to be set in place so that these groups of patients can be protected from acquiring the disease. And for those who are already infected, a more careful follow-up and management should be given so that complication and death can be prevented. Furthermore, considering the above non respiratory symptoms as disease severity indicator could be important.
