‘Every day was a learning curve’: the experience of implementing COVID-19 triage protocols in UK ambulance services – a qualitative study

BackgroundTRIM is an evaluation of the models used to triage and manage emergency ambulance service care for patients with suspected Covid-19 during the first wave of the pandemic in 2020. We aimed to understand experiences and concerns of clinical and managerial staff about implementation of triage protocols in call centre and on-scene.MethodsResearch paramedics in four study sites across England interviewed purposively selected stakeholders from ambulance services (call handlers, clinical advisors in call centres, clinicians providing emergency response, managers) and ED clinical staff from one hospital per site. Interviews (n=23) were conducted remotely using MS Teams, recorded, and transcribed in full. Analysis generated themes from the implicit and explicit ideas within participants’ accounts, following the six stages of analysis described by Braun and Clarke, conducted by a group of researchers and PPI partners working together.ResultsWe identified the following themes:Constantly changing guidelines – at some points, updates several times a dayThe ambulance service as part of the wider healthcare system - changes in other parts of the healthcare system left ambulance services as the default optionPeaks and troughs of demand - demand fluctuated greatly over time, with workload varying across the ambulance service, including an increased role for clinical advisorsA stretched system - resources to respond to patient demand were stretched thinner by staff sickness and isolation, longer job times, and increased handover delays at EDEmotional load of responding to the pandemic - particularly for call centre staffDoing the best they can in the face of uncertainty - in the face of a rapidly evolving situation unlike any which ambulance services had faced beforeDiscussionImplementing triage protocols in response to the Covid-19 pandemic was a complex and process which had to be actively managed by a range of front line staff, dealing with external pressures and a heavy emotional load.

Science at Sundance 2021

Like most events that have taken place since March of last year, the Sundance Film Festival—normally hosted in the cozy ski town of Park City, Utah—was held virtually in 2021. But what it lacked in celebrity sightings and snowy ambiance was more than made up for in the festival's assortment of provocative and timely offerings—from gripping accounts of the COVID-19 pandemic and California's wildfire crisis to mind-bending meditations on the limits of perception and the nature of reality. Read on to see what our reviewers thought of nine of the films that featured strong science and technology themes.

A Novel Cohorting and Isolation Strategy for Suspected COVID-19 Cases during a Pandemic (preprint)

Introduction The COVID-19 pandemic presents a significant infection prevention and control challenge. The admission of large numbers of patients with suspected COVID-19 disease risks overwhelming the capacity to protect other patients from exposure. The delay between clinical suspicion and confirmatory testing adds to the complexity of the problem. Methods We implemented a triage tool aimed at minimising hospital acquired COVID-19 particularly to patients at risk of severe disease. Patients were allocated to triage categories defined by likelihood of COVID-19 and risk of a poor outcome. Category A (low-likelihood; high-risk), B (high-likelihood; high-risk), C (high-likelihood; low-risk) and D (low-likelihood; low-risk). This determined the order of priority for isolation in single-occupancy rooms with Category A the highest. Patients in other groups were cohorted when isolation capacity was limited with additional interventions to reduce transmission. Results 93 patients were evaluated with 79 (85%) receiving a COVID-19 diagnosis during their admission. Of those without a COVID-19 diagnosis: 10 were initially triaged to Category A; 0 to B; 1 to C and 4 to D. All high risk patients requiring isolation were, therefore, admitted to single-occupancy rooms and protected from exposure. 28 (30%) suspected COVID-19 patients were evaluated to be low risk (groups C & D) and eligible for cohorting. No symptomatic hospital acquired infections were detected in the cohorted patients. Discussion Application of a clinical triage tool to guide isolation and cohorting decisions may reduce the risk of hospital acquired transmission of COVID-19 especially to individuals at the greatest of risk of severe disease.
