Lessons learned from the COVID-19 pandemic: Improving initial investigations with the implementation of a COVID-19 blood request panel.

BACKGROUND: During the COVID-19 pandemic, the Hillingdon Hospitals NHS Foundation Trust produced trust guidelines for the initial blood investigation of COVID-19 inpatients. However, insufficient education meant inconsistent adherence to this guidance. OBJECTIVE: To examine whether the implementation of a COVID-19 blood request panel improves adherence to local trust guidelines. METHOD: Between March and April 2020, initial blood investigations performed for positive COVID-19 cases were compared to guidelines. Results were presented locally and a COVID-19 panel was added to the electronic system that provided prompts for appropriate investigations. A re-audit between May and June 2020 was conducted to assess adherence post-intervention. RESULTS: 383 patients were identified in the initial audit cohort and a sample of 20 patients were re-audited. Adherence to Full Blood Count, Urea and Electrolytes, C-reactive Protein and Liver Function Tests increased to 100% from 99.7% (p = 0.8), 99.2% (p = 0.69), 98.7% (p = 0.61), and 96.6% (p = 0.4) respectively. Coagulation screen adherence increased to 90% from 72.8% (p = 0.09). Appropriate requesting of D dimers increased to 50% from 19.9% (p = 0.001). Inappropriate troponin requesting decreased to 26.3% from 38.9% (p = 0.23). CONCLUSION: A user-friendly COVID-19 panel of investigations resulted in improved adherence to guidelines. Clear communication and education are essential to help alleviate uncertainty during a pandemic.

Referral patterns for catheter-directed thrombolysis for iliofemoral deep venous thrombosis.

OBJECTIVES: Post thrombotic syndrome (PTS) is a serious complication of deep venous thromboses (DVTs). PTS occurs more frequently and severely following iliofemoral DVT compared to distal DVTs. Catheter directed thrombolysis (CDT) of iliofemoral DVTs may reduce PTS incidence and severity.We aimed to determine the rate of iliofemoral DVT within our institution, their subsequent management, and compliance with NICE guidelines. METHODS: Retrospective review of all DVTs diagnosed over a 3-year period was conducted. Cases of iliofemoral DVT were identified using ICD-10 codes from patient notes, and radiology reports of Duplex scans. Further details were retrieved, such as patient demographics and referrals to vascular services. NICE guidance was applied to determine if patients would have been suitable for CDT. A survey was sent to clinicians within medicine to identify awareness of CDT and local guidelines for iliofemoral DVT management. RESULTS: 225 patients with lower limb DVTs were identified. Of these, 96 were radiographically confirmed as iliofemoral DVTs. The median age was 77. 67.7% of iliofemoral DVTs affected the left leg. Right leg DVTs made up 30.2% and 2.1% were bilateral DVTs. Of the 96 iliofemoral DVTs, 21 were deemed eligible for CDT. Only 3 patients (14.3%) were referred to vascular services, and 3 received thrombolysis.From our survey, 95.5% of respondents suggested anticoagulation alone as management for iliofemoral DVT. Only one respondent recommended referral to vascular services. There was a knowledge deficiency regarding venous anatomy, including superficial versus deep veins. CONCLUSIONS: CDT and other mechanochemical procedures have been shown to improve outcomes of patients post-iliofemoral DVT, however a lack of awareness regarding CDT as a management option results in under-referral to vascular services. We suggest closer relations between vascular services and their "tributary" DVT clinics, development of guidelines and robust care pathways in the management of iliofemoral DVT.

COVID-19: experience and development of simulation for training in a London District General Hospital.

The world is facing an unprecedented crisis in the form of the coronavirus disease-2019 (COVID-19) pandemic. Clinicians and their working environments are under considerable pressures that have not previously been encountered. Consequently, clinicians have had to change their practice significantly to enable safe care for their patients, whilst ensuring their own safety. The majority of COVID-19 simulation to date has been either virtual or in-situ, with the aim of training specific departments. With this in mind, as the Hillingdon Hospital Education Team, we developed a simulation that would provide generic training on COVID-19 for staff across our Trust in various departments and roles. Our aim was to teach staff how to manage patients whilst protecting themselves during this pandemic.
