Utility of Thromboelastography and velocity curve derivative in diagnosing COVID-19 associated coagulopathy.

BACKGROUND: COVID-19 associated coagulopathy (CAC) can either be localized or systemic hypercoagulable state with increased risk of thromboembolism. This study looked into the usefulness of Thromboelastography (TEG) and the velocity curve (V-curve) derivative from TEG in diagnosing and differentiating different stages of CAC. MATERIALS AND METHODS: A prospective single cohort study of RT-PCR confirmed COVID-19 patients was carried out for 2 weeks. Severe COVID-19 patients in the adult critical care units with a TEG report were recruited for the study. Citrated kaolin TEG was performed on the day of admission before anticoagulation. TEG parameters included were R and K time, alpha angle, maximum amplitude, clotting index, lysis at 30 min. The first-degree velocity curve of TEG is plotted as V-curve which extrapolates thrombus generation potential. Parameters analyzed were the maximum rate of thrombus generation as well as thrombus generated (TG). RESULTS: The study included 43 patients with an average age of 58.34 (±15.35). TEG as well as V-curve of all the patients were hypercoagulable compared with age-matched reference range. We had 79.06% of patients in hypercoagulable stage. The mortality rate was 32.56% and 30.23% developed thrombotic incidents. Patients who succumbed to death had prolonged PT, aPTT, MA, Ly30, with a reduced TG (p < .05). The presence of fibrinolysis was associated with thromboembolism (OR = 6.76, CI = 1.48-25.82). Repeat TEG was done randomly in 11 patients and revealed a persistent hypercoagulable stage with increasing fibrinolysis activity. CONCLUSION: TEG is a useful tool in diagnosing and categorizing Coagulopathy associated with COVID-19.

Portable Biosafety Barrier Innovations to Limit Transmissibility of Infectious Diseases during Patient Care in Resource-limited Settings during the COVID-19 Pandemic.

Background: The coronavirus disease-2019 (COVID-19) pandemic has brought about a change in healthcare practices that are likely to persist into the foreseeable future. In particular, is the exposure risk to the healthcare practitioners in the emergency department (ED) and the intensive care units. Mitigating this issue in a low-resource setting remains challenging, and in particular, in developing nations such as India, where ED patient flows can overwhelm a system and its human resources, breaking down processes and infecting healthcare workers (HCWs). Technique: To tackle this and the possible lack of appropriate personal protective equipment (PPE), we designed and built biosafety barrier devices using local resources for use in patient stabilization, transport, and continued care in the ED or the intensive care units. Results: Four biosafety devices bio-safe levels 1 and 2, ultra-ductile portable interface of interventions in infections, and tented transport trolley for transmissibility (4T) were tested for the feasibility of usage for patient care during the pandemic with simulation. Conclusion: We anticipate that with time it may be common practice for in situ isolation of patients in the emergency departments with a suspicion of an infectious disease. With the proof of concept, simulation, hospital infection control committee (HICC) approval, and trial run, we look to close the gaps that exist in these initial innovations.

COVID-19 Palliative and End-of-Life Care Plan: Development and Audit of Outcomes.

Objectives: Palliative care (PC) referral in serious and critical COVID-19 improves decision-making, health resource utilisation, end-of-life symptom management and family support. In this study, we explored developing a systematic decision-making matrix for PC referral in COVID-19 and audited its outcomes. Materials and Methods: A team of interdisciplinary experts developed a hospital COVID-19 PC plan. PC referral and outcomes of PC referral in hospitalised COVID-19 patients were audited. Results: Out of 1575 inpatients, 1066 (67.7%) had mild and 509 (32.3%) had serious and critical COVID-19 illness. Among 50 (3.1%) referred to PC, 5 (0.4%) had mild and 45 (8.8%) had serious and critical COVID-19 illness. Out of 45 serious and critical COVID-19 patients referred to PC, 38 (84%) received end-of-life care (EOLC), 4 (9%) self-discharged against medical advice and 3 (7%) recovered. Forty-seven (94%) were referred for goals-of-care discussion. About 78% received opioids, 70% benzodiazepines and 42% haloperidol for symptom management. Among 45 serious and critical COVID-19 patients referred to PC, foregoing life-sustaining treatment was documented in 43 (96%) but implemented only in 23 (53%). Out of 38 who received EOLC, ICU was the place of death in 31 (82%) and ward in 7 (18%). Conclusion: Despite interdisciplinary experts developing a hospital COVID-19 PC, low referral of serious and critical COVID-19 patients to PC was observed. PC referral enabled access to management of end-of-life symptoms and facilitated limitation of life-sustaining treatment in some COVID-19 patients with serious illness. Educating critical care physicians about the scope of PC in the COVID-19 setting might improve PC referral.

Assessment of the Preparedness and Planning of Academic Emergency Departments in India During the COVID-19 Pandemic: A Multicentric Survey.

OBJECTIVE: Emergency medicine being a young specialty in India, we aimed to assess the level of disaster preparedness and planning strategies among various academic emergency departments (EDs) across India during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: A cross-sectional multicentric survey was developed and disseminated online to various academic EDs in India and followed up over a period of 8 wk. All results were analyzed using descriptive statistics. RESULTS: Twenty-eight academic emergency medicine departments responded to the study. Compared with pre-COVID period, COVID-19 pandemic has led to 90% of centers developing separate triage system with dedicated care areas for COVID suspected/infected in 78.6% centers with nearly 70% using separate transportation pathways. Strategizing and executing the Institutional COVID-19 treatment protocol in 80% institutes were done by emergency physicians. Training exercises for airway management and personal protective equipment (PPE) use were seen in 93% and 80% centers, respectively. Marked variation in recommended PPE use was observed across EDs in India. CONCLUSIONS: Our study highlights the high variance in the level of preparedness response among various EDs across India during the pandemic. Preparedness for different EDs across India needs to be individually assessed and planned according to the needs and resources available.

Infection Control Measures, in situ Simulation, and Failure Modes and Effect Analysis to Fine-Tune Change Management during COVID-19.

Coronavirus disease 2019 (COVID-19) was an impetus for a multitude of transformations - from the ever-changing clinical practice frameworks, to changes in our execution of education and research. It called for our decisiveness, innovativeness, creativity, and adaptability in many circumstances. Even as care for our patients was always top priority, we tried to integrate, where possible, educational and research activities in order to ensure these areas continue to be harnessed and developed. COVID-19 provided a platform that stretched our ingenuity in all these domains. One of the mnemonics we use at SingHealth in responding to crisis is PACERS: P: Preparedness (in responding to any crisis, this is critical) A: Adaptability (needed especially with the ever-changing situation) C: Communications (the cornerstone in handling any crisis) E: Education (must continue, irrespective of what) R: Research (new opportunities to share and learn) S: Support (both physical and psychological). This article shares our experience integrating the concept of simulation-based training, quality improvement, and failure mode analysis.
