The Winter Society for Acute Medicine Benchmarking Audit (SAMBA) provides the first comparison of performance within acute medicine against clinical quality indicators during winter, a time of increased pressure and demand on acute services.
105 hospitals participated in Winter SAMBA, collecting data over 24-hours on 30th January 2020. 5626 patients were included. Participating units saw a median of 48 patients (range 13-131).
Comparison between Winter SAMBA and SAMBA19 found less patients had an early warning score within 30 minutes during winter (74.3% vs 78.9%) and less were seen by a clinical decision maker within four hours (84.9% vs 87.9%). Unplanned admissions represented a higher proportion of workload (92.5% vs 90.1%). Patients were more likely to have a NEWS2 score of 3 or higher (30.1% vs 25.7%).
Performance is poorer in winter, and patients are more unwell, needing prompt treatment. Services should ensure high quality care can be maintained through times of increased pressure, including winter.

Objective: To ensure clinicians can rely on point-of-care testing results, we assessed agreement between point-of-care tests for creatinine, urea, sodium, potassium, calcium, Hb, INR, CRP and subsequent corresponding laboratory tests.
Participants: Community-dwelling adults referred to a community-based acute ambulatory care unit.
Interventions: The Abbott i-STATTM (Hb, clinical chemistry, INR) and the AfinionTM Analyser (CRP) and corresponding laboratory analyses.
Outcomes: Agreement (Bland-Altman) and bias (Passing-Bablok regression).
Results: Among 462 adults we found an absolute mean difference between point-of-care and central laboratory analyses of 6.4g/L (95%LOA -7.9 to +20.6) for haemoglobin, -0.5mmol/L (95%LOA -4.5 to +3.5) for sodium, 0.2mmol/L (95%LOA -0.6 to +0.9) for potassium, 0.0mmol/L (95%LOA -0.3 to +0.3) for calcium, 9.0 μmol/L (95%LOA -18.5 to +36.4) for creatinine, 0.0mmol/L (95%LOA -2.7 to +2.6) for urea, -0.2 (95%LOA -2.4 to +2.0) for INR, -5.0 mg/L (95%LOA -24.4 to +14.4) for CRP.
Conclusions: There was acceptable agreement and bias for these analytes, except for haemoglobin and creatinine.

Fluid resuscitation is a widely-used treatment in acute and emergency medicine, however, the process used to perform a fluid assessment has never been studied. This qualitative study explored how acute physicians describe their approach to assessing for fluid resuscitation. 18 clinicians of varying grades consented to a semi-structured interview. Transcripts were coded and analysed using thematic analysis. Participants described three subtypes of assessment; screening assessment, emergency assessment and formal assessment. Whether a patient was ‘sick’ was key to determining which assessment they would receive. Marked heterogeneity was noted in the assessment processes, particularly regarding the use of history-taking. Further research is required to determine how the information gathered in these assessments is used to decide when fluid resuscitation is indicated.

Introduction: Advances in ultrasound technology have allowed an investigation previously restricted to the radiology department to be used more liberally in clinical decision making. Point-of-Care-Ultrasound (PoCUS) has superior diagnostic performance to traditional clinical examination across a range of pathologies in the hands of a suitably experienced practitioner. The utilisation of PoCUS has the potential to greatly influence the delivery of acute care, but little is known about the current level of resource provision within the acute medical setting.
Methods: To establish the availability of ultrasound equipment and appropriately trained clinicians within Acute Medical Units (AMUs) in the United Kingdom (UK) we asked specific questions with an annual day of care survey, undertaken by the Society for Acute Medicine. We compared data across two years to assess interval changes.
Results: 58.1% (75/129) of AMUs had access to dedicated ultrasound equipment in SAMBA’19. This represents a small increase from SAMBA’18. Ultrasound expertise is concentrated across a small number of AMUs. Growth in the number of ultrasound trained clinicians is greatest units with established expertise.
Conclusion: The equipment to provide PoCUS is not present on all AMUs and appropriately trained clinicians are not distributed evenly across units. This is likely to affect individual AMUs ability to deliver bedside ultrasound to appropriate patients who may benefit. Bridging the gap to ensure all AMUs have the option to use PoCUS will require planning and investment.

Pulmonary embolism (PE) is a common and potentially life-threatening condition encountered routinely in acute care. The diagnosis and management of PE has been the topic of National Institute of Health Care Excellence and European Cardiology Society guidelines.
