ABSTRACT
Aim: The PINETREE study showed benefit of remdesivir in non-hospitalised COVID patients. This became the evidence base for the NHSE policy on antivirals use in hospital-onset COVID patients. However, there are differences between PINETREE inclusion criteria and NHSE policy eligibility criteria, and PINETREE was conducted when Delta was dominant. We describe attributes, risk stratification and outcomes in hospital-onset COVID patients when Omicron is dominant. Method(s): A retrospective analysis of patients testing COVID +ve post-admission over 30 days at two district hospitals, collecting risk factors as defined by the QCovid model, and outcomes including days on/off oxygen, survival/discharge at 28 days, and whether antivirals were considered/given. Result(s): 68 eligible cases were identified. CV followed by respiratory diseases were the commonest risk factors. In the 28 days after a +ve test, 31% required supplemental oxygen and 16% died. Being male, and having CV disease, active solid malignancy and recent chemo/radiotherapy were over-represented in patients who died. Supplemental oxygen was associated with significantly higher 28-day mortality risk (43% v 4.3%). Average age of those who died was higher than the overall cohort (84 v 75y). 28-day mortality rates for those who received 1, 2 and 3 COVID vaccines were 60%, 21% and 5% respectively. 18 patients met criteria for highest risk group and were eligible for antivirals. Only 11% were considered for antivirals. Conclusion(s): Despite the milder omicron variant and high vaccination rate, hospital-onset COVID is associated with worse outcomes compared to community clinical trials. The lack of antivirals use according to NHSE criteria should push MDTs to consider a validated risk model for antivirals use.
ABSTRACT
Background: Acute respiratory distress syndrome (ARDS) is characterized by hypoxemia and non-hydrostatic pulmonary edema. While ARDS is associated with a high mortality rate, its conjunction with cardiogenic shock (CS) can lead to devastating outcomes. ARDS is managed via lung protective ventilation with low tidal volumes and positive end expiratory pressures. Prone positioning has emerged as a supplementary strategy with beneficial effects on gas exchange, respiratory mechanics, and hemodynamics. Our case underlines the feasibility of intra-aortic balloon pump counterpulsation (IABP) with concurrent prone positioning in a patient with ARDS and CS. Case: 71-year-old male with history of coronary artery disease, hypertension, hyperlipidemia, and chronic kidney disease, presented to the emergency department with new onset chest pain. EKG showed ST-segment elevations in leads V1-V2 consistent with acute anterior wall myocardial infarction. Patient underwent percutaneous coronary intervention to the left anterior descending artery.Due to worsening hemodynamics and CS, it was decided to place a left axillary IABP. Hospital course was further complicated by acute pulmonary edema and ARDS requiring emergent intubation and mechanical ventilation. Patient was also started on renal replacement therapy given progression of renal failure. Decision-making: Given the onset of ARDS, the patient was placed in prone position for 12-16 hours/day for 5 days. There was no special technique required during proning, other than additional staff to ensure IABP stability. Gradual improvement in hemodynamics was attained, including an increase in cardiac index from 2.1 to 3.4, and a decrease in pulmonary vascular congestion. Conclusion: With the emergence of COVID-19 pandemic, the incidence of ARDS has increased significantly, with simultaneous occurrence of CS in some of these patients. Prone positioning has become one of the main therapeutic modalities in the management of ARDS. Our case highlights the feasibility of axillary IABP while implementing prone positioning in patients with concomitant ARDS and CS.
