Variation in general practice referral rate to acute medicine services and association with hospital admission. A retrospective observational study.

BACKGROUND: Variation in general practice (GP) referral rates to outpatient services is well described however variance in rates of referral to acute medical units is lacking. OBJECTIVE: To investigate variance in GP referral rate for acute medical assessment and subsequent need for hospital admission. METHODS: A retrospective cohort study of acute medical referrals from 88 GPs in Lothian, Scotland between 2017 and 2020 was performed using practice population size, age, deprivation, care home residence, and distance from hospital as explanatory variables. Patient-level analysis of demography, deprivation, comorbidity, and acuity markers was subsequently performed on referred and clinically assessed acute medical patients (n = 42,424) to examine how practice referral behaviour reflects clinical need for inpatient hospital care. RESULTS: Variance in GP referral rates for acute medical assessment was high (2.53-fold variation 1st vs. 4th quartile) and incompletely explained by increasing age and deprivation (adjusted R2 0.67, P < 0.001) such that significant variance remained after correction for confounders (2.15-fold). Patients from the highest referring quartile were significantly less likely to require hospital admission than those from the third, second, or lowest referring quartiles (adjusted odds ratio 1.28 [1.21-1.36, P < 0.001]; 1.30 [1.23-1.37, P < 0.001]; 1.53 [1.42-1.65, P < 0.001]). CONCLUSIONS: High variation in GP practice referral rate for acute medical assessment is incompletely explained by practice population socioeconomic factors and negatively associates with need for urgent inpatient care. Identifying modifiable factors influencing referral rate may provide opportunities to facilitate community-based care and reduce congestion on acute unscheduled care pathways.

Managing the populations need for urgent medical care is challenge in many healthcare systems and overcrowding of urgent medical services negatively affects patient experience and can affect timely treatment. In the United Kingdom, the primary sources of patients attending for acute medical care are self-attendance to the hospital or by way of referral by a primary care physician (general practitioner). These data for the first time demonstrate high variation in referral rates for acute medical assessment between general practices which is incompletely explained by factors such as the age, deprivation, distance to the hospital or care home residence status of the care home population. Analysis of over 40,000 of these referrals for urgent medical care was subsequently undertaken to further investigate this variation. After adjusting for important clinical factors, patients referred from "high referring" practices were over 50% less likely to require inpatient hospital care than patients from lower referring practices. This suggests that the threshold for referral varies greatly between individual primary care clinicians, practices, or practice populations and many of these patients may have been suitable for less urgent community-based care. Identification of modifiable factors that account for this unexplained variation may facilitate community-based care and improve patient experience by reducing unnecessary attendance and congestion in already busy emergency care services.

A young breathless patient.

A 34-year-old gentleman, with a background of osteoarthritis, presented to the Acute Medical Unit with a short history of breathlessness. He had returned from holiday to the United States five days previously. Since return, he had complained of myalgia, sore throat, a non-productive cough, mild anorexia and fevers at home. More acutely, prompting his presentation to hospital, was acute dyspnoea, which was sudden onset, with some central anterior chest discomfort and worse lying flat.

Improving the management and care of people with sepsis.

Many hospitals struggle to implement the full sepsis care bundle, but research suggests that many patients with sepsis are transported to hospital by ambulance. In 2011, the Scottish Ambulance Service introduced a pre-hospital sepsis screening tool (PSST) to expedite sepsis identification and care delivery. However, ambulance clinicians have reported varying degrees of interest and enthusiasm from hospital staff during handover. Therefore, an online survey was set up to investigate medical and nursing staff perceptions and experiences of the introduction of a PSST. This article discusses the results, which show that participants perceive the PSST reduces time to treatment, improves continuity of care, benefits patients and is accurately applied by ambulance clinicians, but which also highlight problems with communication. The delivery of in-hospital and pre-hospital sepsis care is challenging, but simple measures such as improving and standardising communication and alert systems between ambulance services and receiving hospitals could improve the clinical effects of a PSST.

The ACUMEN project.

E-learning for healthcare (e-LfH) is a collaborative programme between the Department of Health, the NHS and various professional bodies. It provides high quality, interactive education for healthcare workers, and has been described as 'The most positive development in medical education in 20 years' by the Chief Medical Officer, Sir Liam Donaldson. Indeed e-LfH have recently been awarded the elearning age 2007 Gold award for 'Excellence in the production of e-learning content'.
