Clinical characteristics and outcomes of people with severe mental disorders hospitalized due to COVID-19: A nationwide population-based study

ObjetiveHospitalized COVID-19 patients with severe mental illness (SMI) have worse outcomes than counterparts without SMI. Barriers in access to acute care medical procedures among SMI patients may partially explain this phenomenon. Here, we examined differences in critical care admission and in-hospital mortality between hospitalized COVID-19 patients with and without SMI. MethodsThis population-based study used Spain's nationwide electronic health records. Based on International Classification Diseases, Tenth Revision, ICD-10-CM codes, we identified all patients aged ≥15 years hospitalized due to COVID-19 between July 1st-December 31st, 2020, and compared patients with and without SMI in terms of (i) critical care admission and (ii) in-hospital mortality – overall and stratified by age. We used logistic regression models including sex, age, and comorbidity burden as measured by Charlson Comorbidity Index Score as covariates. ResultsOf 118,691 hospital admissions due to COVID-19 of people aged ≥15 years, 1512 (1.3%) included a diagnosis of SMI. Compared to non-SMI patients, SMI patients had higher in-hospital mortality (OR,95%CI: 1.63,1.42–1.88) and were less frequently admitted to critical care (OR,95%CI: 0.70,0.58–0.85). Admission to critical care in SMI patients was lower than for non-SMI counterparts only among individuals aged ≥60 years. The magnitude of the difference in in-hospital mortality between SMI and non-SMI patients decreased as age increased. ConclusionsIndividuals with SMI had reduced critical care admission and increased in-hospital mortality compared non-SMI counterparts, suggesting that differences in delivery of acute care medical procedures may partially explain higher risk of negative outcomes among COVID-19 patients with SMI.

Postoperative Critical Care Admission Was Not Associated with Improved Postoperative Outcomes in Elective Colorectal Surgery: Secondary Analysis Of POWER Trial

BackgroundThe efficacy of routine admission of high-risk patients to a critical care unit after surgery is not clear. The aim of our study was to investigate the association between critical care admission after scheduled colorectal surgery and postoperative complications, 30-day mortality, and length of stay in hospital. MethodsA pre-defined secondary substudy of POWER study was performed. POWER study was a prospective multicenter observational study of patients undergoing elective primary colorectal surgery during a single period of two months of recruitment between September and December 2017. ResultsA total of 2084 patients from 80 Spanish hospitals were included, of which 722 (34.6%) were admitted to critical care unit (CCU) after elective surgery. After adjusting for confounding factors in the multivariate analysis, postoperative CCU admission was independently associated with a higher incidence of moderate-to-severe postoperative complications (adjusted OR 1.951, 95% CI 1.570, 2.425; p < 0.001). Regarding secondary outcomes, postoperative critical care admission was independently associated with higher 30-day mortality (adjusted OR 6.736; 95% CI 2.507, 18.101; p < 0.001) and independently associated with an increased hospital length of stay (adjusted OR 1.143, 95% CI 1.112, 1.175; p < 0.001). ConclusionsDirect admission to CCU after scheduled colorectal surgery was not associated with a reduction in moderate-to-severe postoperative complications.

Complementary value of the Shock Index v. the Modified Shock Index in the prediction of in-hospital intensive care unit admission and mortality: A single-centre experience.

Shock is a state of circulatory insufficiency that creates an imbalance between tissue oxygen supply and demand, resulting in end-organ dysfunction and hypodynamic circulatory failure. Most patients with infectious and trauma-related illnesses present to the emergency department (ED) in shock. To study the usefulness of the shock index (SI) and modified shock index (MSI) in identifying and triaging patients in shock presenting to the ED. This was a year-long observational, cross-sectional study of 290 patients presenting to the ED of a tertiary hospital in compensated or overt shock. The SI and MSI were calculated at the time of first contact, and then hourly for the initial 3 hours. Relevant background investigations targeting the cause of shock and prognostic markers were done. The outcome measures of mortality and intensive care unit admission were documented for each participant. The mean age of the participants was 49 years, and 67% of them were men. In consensus with local and national data, the major medical comorbidities were hypertension (20%) and diabetes mellitus (16%). An SI ≥0.9 and an MSI ≥1.3 predicted in-hospital mortality (p<0.05) and ICU admission (p<0.05) with no significant superiority of the MSI over the SI in terms of mortality, although the MSI was a better surrogate marker for critical care admission. The study showed the complementary value of the SI and MSI in triage in a busy tertiary hospital ED, surpassing their components such as blood pressure, heart rate and pulse pressure. We determined useful cut-offs for these tools for early risk assessment in the ED, and larger multicentre studies are needed to support our findings. What the study adds. The study highlights the usefulness of clinical bedside tools such as the shock index (SI) and modified shock index (MSI) in triaging patients in the emergency department, and their role in predicting morbidity and mortality.Implications of the findings. Compared with systolic blood pressure, diastolic blood pressure and mean arterial pressure, alone or in combination, the SI and MSI had higher sensitivity and specificity in terms of outcome prediction. While both an elevated SI and an elevated MSI predicted in-hospital mortality, the MSI was a better surrogate marker for ICU admission.

Using technology to reduce critical deterioration (the DETECT study): a cost analysis of care costs at a tertiary children's hospital in the United Kingdom

BackgroundElectronic early warning systems have been used in adults for many years to prevent critical deterioration events (CDEs). However, implementation of similar technologies for monitoring children across the entire hospital poses additional challenges. While the concept of such technologies is promising, their cost-effectiveness is not established for use in children. In this study we investigate the potential for direct cost savings arising from the implementation of the DETECT surveillance system.MethodsData were collected at a tertiary children’s hospital in the United Kingdom. We rely on the comparison between patients in the baseline period (March 2018 to February 2019) and patients in the post-intervention period (March 2020 to July 2021). These provided a matched cohort of 19,562 hospital admissions for each group. From these admissions, 324 and 286 CDEs were observed in the baseline and post-intervention period, respectively. Hospital reported costs and Health Related Group (HRG) National Costs were used to estimate overall expenditure associated with CDEs for both groups of patients.ResultsComparing post-intervention with baseline data we found a reduction in the total number of critical care days, driven by an overall reduction in the number of CDEs, however without statistical significance. Using hospital reported costs adjusted for the Covid-19 impact, we estimate a non-significant reduction of total expenditure from £16.0 million to £14.3 million (corresponding to £1.7 million of savings – 11%). Additionally, using HRG average costs, we estimated a non-significant reduction of total expenditure from £8.2 million to £ 7.2 million (corresponding to £1.1 million of savings – 13%).Discussion and conclusionUnplanned critical care admissions for children not only impose a substantial burden on patients and families but are also costly for hospitals. Interventions aimed at reducing emergency critical care admissions can be crucial to contribute to the reduction of these episodes’ costs. Even though cost reductions were identified in our sample, our results do not support the hypothesis that reducing CDEs using technology leads to a significant reduction on hospital costs.Trial registrationCurrent Controlled Trials ISRCTN61279068, date of registration 07/06/2019, retrospectively registered.

A Prospective Cohort Study (OUTSTRIP-COVID) on Functional and Spirometry Outcomes in COVID-19 ICU Survivors at 3 Months.

COVID-19 pandemic resulted in a significant number of critical care admissions secondary to severe pneumonia and acute respiratory distress syndrome. We evaluated the short-, medium- and long-term outcomes of lung function and quality of life in this prospective cohort study and reported the outcomes at 7 weeks and 3 months from discharge from intensive care unit. A prospective cohort study of ICU survivors with COVID-19 was conducted from August 2020 to May 2021 to evaluate baseline demographic and clinical variables as well as determine lung function, exercise capacity, and health-related quality of life (HRQOL) using spirometry and 6-minute walk test (6MWT) conducted in accordance with American Thoracic Society standards, and SF-36 (Rand), respectively. SF-36 is a generic 36 question standardized health survey. Descriptive and inferential statistics (alpha = 0.05) were used to analyse the data. At baseline, 100 participants were enrolled in the study of whom 76 followed up at 3 months. Majority of the patients were male (83%), Asians (84%) and less than 60 years of age (91%). HRQOL showed significant improvement in all domains of SF-36, except in emotional wellbeing. Spirometry variables also showed significant improvement in all variables over time with greatest improvement in percentage predicted Forced expiratory volume 1 (79% vs 88% p < 0.001). 6MWT showed significant improvement in variables of walk distance, dyspnea, and fatigue with greatest improvement in change in oxygen saturation (3% vs 1.44% p < 0.001). Intubation status did not impact the changes in SF-36, spirometry or 6MWT variables. Our findings suggest that ICU survivors of COVID-19 have significant improvement in their lung function, exercise capacity and HRQOL within 3 months of ICU discharge regardless of intubation status.

Targeted temperature management in patients with intracerebral haemorrhage, subarachnoid haemorrhage, or acute ischaemic stroke: updated consensus guideline recommendations by the Neuroprotective Therapy Consensus Review (NTCR) group

BackgroundThere is a lack of consistent, evidence-based guidelines for the management of patients with fever after brain injury. The aim was to update previously published consensus recommendations on targeted temperature management after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in patients who require admission to critical care. MethodsA modified Delphi consensus, the Neuroprotective Therapy Consensus Review (NTCR), included 19 international neuro-intensive care experts with a subspecialty interest in the acute management of intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke. An online, anonymised survey was completed ahead of the meeting before the group came together to consolidate consensus and finalise recommendations on targeted temperature management. A threshold of ≥80% for consensus was set for all statements. ResultsRecommendations were formulated based on existing evidence, literature review, and consensus. After intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in patients who require critical care admission, core temperature should ideally be monitored continuously and maintained between 36.0°C and 37.5°C using automated feedback-controlled devices, where possible. Targeted temperature management should be commenced within 1 h of first fever identification with appropriate diagnosis and treatment of infection, maintained for as long as the brain remains at risk of secondary injury, and rewarming should be controlled. Shivering should be monitored and managed to limit risk of secondary injury. Following a single protocol for targeted temperature management across intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke is desirable. ConclusionsBased on a modified Delphi expert consensus process, these guidelines aim to improve the quality of targeted temperature management for patients after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in critical care, highlighting the need for further research to improve clinical guidelines in this setting.

Emulating Target Trials Comparing Early and Delayed Intubation Strategies

Whether intubation should be initiated early in the clinical course of critically ill patients remains a matter of debate. Results from prior observational studies are difficult to interpret because of avoidable flaws including immortal time bias, inappropriate eligibility criteria, and unrealistic treatment strategies. Do treatment strategies that intubate patients early in the critical care admission improve 30-day survival compared with strategies that delay intubation? We estimated the effect of strategies that require early intubation of critically ill patients compared with those that delay intubation. With data extracted from the Medical Information Mart for Intensive Care-IV database, we emulated three target trials, varying the flexibility of the treatment strategies and the baseline eligibility criteria. Under unrealistically strict treatment strategies with broad eligibility criteria, the 30-day mortality risk was 7.1 percentage points higher for intubating early compared with delaying intubation (95%CI, 6.2-7.9). Risk differences were 0.4 (95%CI, -0.1 to 0.9) and -0.9 (95%CI, -2.5 to 0.7) percentage points in subsequent target trial emulations that included more realistic treatment strategies and eligibility criteria. When realistic treatment strategies and eligibility criteria are used, strategies that delay intubation result in similar 30-day mortality risks compared with those that intubate early. Delaying intubation ultimately avoids intubation in most patients.

Chinese Patients’ and Family Caregivers’ Perception of Care Quality, A Qualitative Study in Australian Hospitals

Cultural diversity in the Australian population is significant. It challenges health professionals in Australia's acute and critical care settings to provide culturally competent care for ethnic minority patients. Chinese Australians are the largest ethnic minority group in Australia. However, their experiences in acute hospital settings remain largely unknown. Studies on this patient group are much needed to address the research gap and add research evidence on transcultural nursing for the international community. The aim of this study was to explore Chinese patients’ and their family caregivers’ perceptions of care quality in Australian hospitals. A qualitative descriptive study design was used in this study. Adult Chinese patients born in mainland China and who had an acute and critical care admission were recruited from metropolitan hospitals in South Australia in 2019 using the snowball method. Semi-structured interviews were conducted in Mandarin. Data were transcribed verbatim in simplified Chinese for thematic analysis. Results were translated to English and checked by a bilingual team member. Ten participants participated in the study. Four main themes were identified from the data analysis: 1) the feeling of being disoriented in the ICU; 2) desire for comfort; 3) lack of engagement in treatment and care plans; and 4) lack of participation in quality improvement feedback to the care system. Chinese people have unique cultural beliefs, communication patterns, and health-seeking behaviors. To provide culturally competent care for acute and critically ill Chinese patients, health professionals are required to incorporate transcultural nursing theory, knowledge, skills, and attitudes into everyday practice.

Epidemiology of childhood acute kidney injury in England using e-alerts.

Few studies describe the epidemiology of childhood acute kidney injury (AKI) nationally. Laboratories in England are required to issue electronic (e-)alerts for AKI based on serum creatinine changes. This study describes a national cohort of children who received an AKI alert and their clinical course. A cross-section of AKI episodes from 2017 are described. Hospital record linkage enabled description of AKI-associated hospitalizations including length of stay (LOS) and critical care requirement. Risk associations with critical care (hospitalized cohort) and 30-day mortality (total cohort) were examined using multivariable logistic regression. In 2017, 7788 children (52% male, median age 4.4 years, interquartile range 0.9-11.5 years) experienced 8927 AKI episodes; 8% occurred during birth admissions. Of 5582 children with hospitalized AKI, 25% required critical care. In children experiencing an AKI episode unrelated to their birth admission, Asian ethnicity, young (<1 year) or old (16-<18years) age (reference 1-<5 years), and high peak AKI stage had higher odds of critical care. LOS was higher with peak AKI stage, irrespective of critical care admission. Overall, 30-day mortality rate was 3% (n=251); youngest and oldest age groups, hospital-acquired AKI, higher peak stage and critical care requirement had higher odds of death. For children experiencing AKI alerts during their birth admission, no association was seen between higher peak AKI stage and critical care admission. Risk associations for adverse AKI outcomes differed among children according to AKI type and whether hospitalization was related to birth. Understanding the factors driving AKI development and progression may help inform interventions to minimize morbidity.

Prevalence of arterial hypertension in pediatric hospitalized patients.

To establish the prevalence of arterial hypertension in pediatric patients hospitalized in a tertiary hospital center in Medellin, Colombia for 6 years. A descriptive cross-sectional study was carried out that reviewed retrospective information obtained from the clinical records of patients under 18 years of age hospitalized at the Pablo Tobón Uribe Hospital in Medellín. From a total of 382 pediatric patients hospitalized in the studied period, a prevalence of hypertension of 30.6% was found. Systolic hypertension prevalence was 23.6% and diastolic 20.7%. Age under 5, treatment with vancomycin and critical care admission increased the risk of being hypertensive during hospitalization. In children the frequency of hypertension in hospitalized patients is higher than the prevalence reported in outpatients. The highest risk group and potentially modifiable factors must be recognized and treatment administered in a timely manner. Secondary complications are low, except for left ventricular hypertrophy, which requires long-term follow-up.

Tracheostomy in Critically Ill COVID-19 Patients on Extracorporeal Membrane Oxygenation: A Single-Center Experience.

Novel coronavirus-19 (COVID-19) has led to over 6 million fatalities globally. An estimated 75% of COVID-19 patients who require critical care admission develop acute respiratory distress syndrome (ARDS) needing invasive mechanical ventilation (IMV) and/or extracorporeal membrane oxygenation (ECMO). Due to prolonged ventilation requirements, these patients often also require tracheostomy. We performed a review of clinical outcomes in COVID-19 patients on ECMO at a high-volume tertiary care center in Hamilton, Ontario, Canada. We performed a retrospective case series, including 24 adult patients diagnosed with COVID-19 who required IMV, veno-venous (ECMO), and tracheostomy. All patients were included from April to December 2021. We extracted demographic and clinical variables pertaining to the tracheostomy procedure and ECMO therapy. We performed descriptive statistical analyses. This study was approved by the Hamilton Integrated Research Ethics Board (14217-C). We included 24 consecutive patients with COVID-19 who required tracheostomy while undergoing ECMO therapy. The mean age was 49.4 years [standard deviation (SD): 7.33], the majority of patients were male (75%), with mean body mass index of 32 (SD: 8.81). Overall mortality rate was 33.3%. Percutaneous tracheostomy was performed most frequently (83.3%) and, similar to open tracheostomy, was associated with a low rate of perioperative bleeding complications. Within surviving patients, the mean time to IMV weaning and decannulation was 60.2 (SD: 24.6) and 49.4 days (SD: 21.8), respectively. Percutaneous tracheostomy appears to be safe in COVID-19 patients on ECMO and holding anticoagulation 24 hours prior to and after tracheostomy may limit bleeding events in these patients.

Association of an Emergency Critical Care Program With Survival and Early Downgrade Among Critically Ill Medical Patients in the Emergency Department.

To determine whether implementation of an Emergency Critical Care Program (ECCP) is associated with improved survival and early downgrade of critically ill medical patients in the emergency department (ED). Single-center, retrospective cohort study using ED-visit data between 2015 and 2019. Tertiary academic medical center. Adult medical patients presenting to the ED with a critical care admission order within 12 hours of arrival. Dedicated bedside critical care for medical ICU patients by an ED-based intensivist following initial resuscitation by the ED team. Primary outcomes were inhospital mortality and the proportion of patients downgraded to non-ICU status while in the ED within 6 hours of the critical care admission order (ED downgrade <6 hr). A difference-in-differences (DiD) analysis compared the change in outcomes for patients arriving during ECCP hours (2 pm to midnight, weekdays) between the preintervention period (2015-2017) and the intervention period (2017-2019) to the change in outcomes for patients arriving during non-ECCP hours (all other hours). Adjustment for severity of illness was performed using the emergency critical care Sequential Organ Failure Assessment (eccSOFA) score. The primary cohort included 2,250 patients. The DiDs for the eccSOFA-adjusted inhospital mortality decreased by 6.0% (95% CI, -11.9 to -0.1) with largest difference in the intermediate illness severity group (DiD, -12.2%; 95% CI, -23.1 to -1.3). The increase in ED downgrade less than 6 hours was not statistically significant (DiD, 4.8%; 95% CI, -0.7 to 10.3%) except in the intermediate group (DiD, 8.8%; 95% CI, 0.2-17.4). The implementation of a novel ECCP was associated with a significant decrease in inhospital mortality among critically ill medical ED patients, with the greatest decrease observed in patients with intermediate severity of illness. Early ED downgrades also increased, but the difference was statistically significant only in the intermediate illness severity group.

SPECIAL CONSIDERATIONS IN CRITICAL CARE OF THE CONGENITAL HEART DISEASE PATIENT.

Outcomes of congenital heart disease have improved markedly over the last 20 years, with survival to adulthood now close to 90%. The mean age of admission to an intensive care unit (ICU) is 40 years. The incidence of hospital and critical care admissions have increased significantly as a consequence of this improved survival. Intensivists are now confronted with the management of complex adult congenital heart disease (ACHD) lesions not only from a cardiac perspective but also extra-cardiac organ consequences of years of abnormal circulation following surgical or palliative correction. Kidney and liver dysfunction, respiratory and hematological abnormalities are very common in this population. ACHD patients can present to the ICU for a vast number of reasons, these are classified in this review as medical non-cardiac, medical cardiac and surgical. Community/hospital acquired infections, cerebrovascular accidents, respiratory failure, alongside arrhythmias and heart failure are responsible for medical admissions. Surgical admissions include post-operative management after correction or palliation, but also medical optimization and work-up for advanced therapies. ICU management of this large heterogeneous group requires a thorough understanding of the pathophysiology in order to apply conventional adult critical care modalities; left ventricular or right ventricular dysfunction, pulmonary hypertension, intracardiac, extracardiac, palliative surgical shunts can be present and require additional consideration. This review focuses on the pathophysiology, long term sequelae, and different treatment modalities to supply a framework for the ICU physician caring for these patients. Successful outcome, especially in complex lesions is dependent on early involvement of specialized ACHD centers.

363 Outcomes in Critical Care Admissions in Peritoneal Dialysis Patients

363 Outcomes in Critical Care Admissions in Peritoneal Dialysis Patients

Immunocompromise among vaccinated versus unvaccinated COVID-19 cases admitted to critical care in Ireland, July to October 2021.

As the COVID-19 pandemic progressed, so too did the proportion of cases admitted to critical care in Ireland who were fully vaccinated. Reporting of this observation has public health implications as incorrect interpretation may affect public confidence in COVID-19 vaccines. A potential explanation is the reduced ability of those who are immunocompromised to produce an adequate, sustained immune response to vaccination. We conducted an analysis of the association between COVID-19 vaccination status and underlying degree of immunocompromise among a cohort of critical care patients all with a confirmed diagnosis of COVID-19 admitted to critical care between July and October 2021. Multinomial logistic regression was used to estimate an odds ratio of immunocompromise among vaccinated COVID-19 cases in critical care compared to unvaccinated cases. In this study, we found a statistically significant association between the vaccination status of severe COVID-19 cases requiring critical care admission and underlying immunocompromise. Fully vaccinated patients were significantly more likely to be highly (OR=19.3, 95% CI 7.7-48.1) or moderately immunocompromised (OR=9.6, 95% CI 5.0-18.1) compared to unvaccinated patients with COVID-19. These findings support our hypothesis, that highly immunocompromised patients are less likely to produce an adequate and sustained immune response to COVID-19 vaccination, and are therefore more likely to require critical care admission for COVID-19 infection.

5613393 PREGNANCY OUTCOMES IN WOMEN WITH SICKLE CELL DISEASE IN IRELAND: A RETROSPECTIVE REVIEW

Background: Sickle cell disease (SCD) is one of the most common single gene disorders worldwide and is characterised by significant morbidity and early mortality.[1] Pregnancy in SCD is associated with an increased risk of maternal and foetal complications.[2,3] The 2011 RCOG and the 2021 BSH guidelines[5,6] on the management of pregnancy in SCD have provided the basis for best practice care in the UK over the past decade and is the guidance which we follow in Ireland. To date, there is no published data on outcomes for pregnant women with SCD in Ireland. The number of Irish patients with SCD has risen over the past 20 years. Without a national database, the exact prevalence is not known but currently there are at least 600 adults and children with SCD in Ireland, whose population is just over 5 million.[4] Aims: Our study assesses outcomes of pregnant patients with SCD from 2015 to 2022. Our aims were to: Assess adherence to current guidelines Assess pregnancy outcomes and maternal complications Assess transfusion rates amongst our patient cohort. Method: This is a retrospective cohort study. We do not have a directly matched cohort, but have compared our findings to published data on Irish pregnancy outcomes from the Irish Maternity Indicator System National Report and have correlated our findings with studies of women with SCD who were managed in UK centres.[8,9,10] Results: We reviewed outcomes of 29 pregnancies in 19 women over a 7-year period. The median age was 29 (range 20-41) and the predominant maternal sickle genotype was HbSS (65.5%). Before conception, 55.2% of cases had pre-existing complications of SCD, including acute chest syndrome (ACS), pulmonary hypertension (PHTN) and prior stroke. In accordance with current guidelines, 100% of women (n=29) were prescribed folic acid, penicillin, and aspirin prophylaxis. 51.7% (n=15) of women had documented maternal complications during pregnancy, including ACS (34%), vaso-occlusive crisis (34%), gestational diabetes (10%), VTE (3%) and UTI (3%). Two women (7%) developed Covid-19 pneumonitis despite vaccination. There was one case of maternal bacteraemia (3%). 65.5% of cases (n=19) required blood transfusion during pregnancy. One woman was already on a blood transfusion programme for disease modification prior to pregnancy. In 6 cases (20.6%), a transfusion programme was commenced during pregnancy due to prior pregnancy complications or intrauterine growth restriction. During pregnancy, 27.6% (n=8) of women required emergency red cell exchange for ACS. Prior studies have suggested that between 30% and 70% of pregnant women with SCD require at least one blood transfusion during pregnancy.[8,9,10] By comparison, only 2.6% of the Irish general obstetric population required transfusion during pregnancy.[7] 20.6% (n=6) of births were preterm at <37 weeks’ gestation. There was one live preterm birth (3%) at <34 weeks and one intrauterine death (3%) at 23 weeks’ gestation. Similar to UK data[9], 31% of women required critical care stay (n=9) during pregnancy, in comparison with 1.44% nationwide in 2020.[7] Conclusion: It is well established that pregnancy in SCD is high risk, and despite adherence to current guidelines, we have shown very high rates of critical care admission, significant transfusion requirement and hospital admissions. Our findings are comparable to published UK outcomes and they further support the need for a comprehensive specialist care setting for this patient cohort.

Caring for two in the ICU: Pharmacotherapy in the critically ill pregnant patient.

Safe and thoughtful medication management of pregnant patients requiring intensive care unit (ICU) level of care is key to optimizing outcomes for both mother and fetus. Pregnancy induces physiologic alterations that closely mirror the changes expected in a critically ill patient. These changes can be predictable depending on the gestational age and trimester and will directly impact the pharmacokinetic profile of medications commonly used in the ICU; examples include decreased gastric emptying, increased blood and plasma volume, increased glomerular filtration, and increased cardiac output. When pregnant patients require ICU care, the resulting impact on drug absorption, distribution, metabolism, and elimination can be difficult to predict. In addition, there are many nuances of medication metabolism and interface with the placental barrier that should be considered when selecting pharmacotherapy for the pregnant patient. Critical care clinicians need to be aware of medication interactions with the placenta and weigh the risk versus benefit profile of medication use in this patient population. Obstetric critical care admissions have increased over the years, especially during the coronavirus waves. Therefore, understanding the interplay between pregnancy and critical illness to optimize pharmacotherapy selection is crucial to improving health outcomes of mother and fetus. This review highlights pharmacotherapy considerations in the pregnant ICU patient for the following topics: physiologic alterations, categorizing medication risk, supportive care, sepsis, cardiogenic shock, acute respiratory distress syndrome, and venous thromboembolism.

Is high sensitivity troponin, taken regardless of a clinical indication, associated with 1 year mortality in critical care patients?

The aim of this study was to assess whether high sensitivity troponin (hs-cTnI) is associated with 1 year mortality in critical care (CC). One year mortality data were obtained from NHS Digital for a consecutive cohort of patients admitted to general CC unit (GCCU) and neuroscience CC unit (NCCU) who had hs-cTnI tests performed throughout their CC admission, regardless of whether the test was clinically indicated. Cox proportional hazards were used to estimate the risk of 1-year mortality. A landmark analysis was undertaken to assess whether any relationship at 1 year was driven by mortality within the first 30 days. A total of 1033 consecutive patients were included. At 1 year 254 (24.6%) patients had died. The admission log(10)hs-cTnI concentration in the entire cohort (HR 1.35 (95% CI 1.05-1.75) p = 0.009 with a bootstrap of 1000 samples) was independently associated with 1 year mortality. On landmark analysis the association with 1 year mortality was driven by 30 day mortality. These results indicate that admission hs-cTnI concentration is independently associated with 1 year mortality in CC and this relationship may be driven by differences in mortality at 30 days.

Undiagnosed Asthma-COPD overlap among patients diagnosed as Asthma and COPD in a referral hospital, India

Patients who have features of both Asthma & COPD are now known as Asthma COPD overlap (ACO). Prevalence of ACO based on the Global Initiative for Asthma (GINA) and Global initiative for obstructive lung disease (GOLD) Syndromic Approach is scarce. In this cross-sectional observational study, we recruited physician-diagnosed–pAsthma, pCOPD & pACO by simple random sampling. Clinical features, spirometry, 6-min walk test, Serum Immunoglobulin E, % blood eosinophils and chest x-rays were reviewed. Syndromic approach was applied, and the diagnosis was reclassified accordingly.In all, 877 patients were included (Male = 445, Female = 432). Physician diagnosis for these were: pAsthma–713, pCOPD–157 and pACO–7. They were reclassified using the Syndromic approach as: sAsthma, sCOPD and sACO. The 713 pAsthmatics were reclassified as follows: sAsthma–684 (95.94%), sCOPD–12 (1.68%) and sACO–17 (2.38%). Of the 157 pCOPD patients, 91 (57.96%) were reclassified as sCOPD, 23 (14.6%) as sACO, and 17 (927.38%) as sAsthma. Of the 7 previously diagnosed pACO patients, only 1 (14.28%) was reclassified as sACO, 5 (71.42%) as sAsthma and 1 (14.28%) as sCOPD. sCOPD patients had more exacerbations (52.88% vs 46.34%, p = 0.479), critical care admissions (16.35% vs 7.32%, p = 0.157) and intubations (17.31% vs 9.76%, p = 0.255) compared to sACO patients, the latter had more events than sAsthma patients: exacerbations 46.34% vs 10.11% (p < 0.001), critical care admissions 7.32% vs 1.64% (p = 0.010) and intubations 9.76% vs 1.5% (p < 0.001).The syndromic approach helped us to identify ACO and also more appropriately classified COPD & Asthma. There was a significant difference between physician diagnosis and diagnosis using Syndromic Approach. It revealed considerable misclassification of several Asthmatic and ACO subjects, who could have been denied inhaled corticosteroids, as they were wrongly categorised as COPD by physician diagnosis.
