Emergency and acute medical care in over 16s: service delivery and organisation.
Show details8. Primary care access to radiology
8.1. Introduction
Diagnostic radiology plays an important role in the diagnosis and management of patients presenting with an acute medical emergency (AME). This can range from simple imaging, such as plain x-ray - chest x-ray or abdominal x-ray, to more specialist tests such as computerised tomography (CT), magnetic resonance imaging (MRI), and ultrasound (US) imaging. There is a strategic drive in the United Kingdom to reduce emergency referrals to hospitals; however, the role of such investigations both in terms of access and same day reporting in a GP setting remains unclear.
While it may be accepted that more specialist tests should be restricted to a hospital setting, there may be a more specific role for plain x-ray radiology, for example, in patients presenting to a GP with a sub-acute breathing problem such as a chest infection, exacerbation of chronic obstructive airways disease or exacerbation of asthma, the role of plain x-ray radiology and reassurance of a normal chest x-ray may avoid unnecessary referral to hospital.
8.2. Review question: Does GP access to radiology with same day results improve outcomes?
For full details see review protocol in Appendix A.

PICO characteristics of review question.
8.3. Clinical evidence

8.6. Recommendations and link to evidence
| Recommendation | - |
| Research recommendation | RR5. What is the clinical and cost effectiveness of providing GPs with access to plain X-ray radiology or ultrasound with same day results? |
| Relative values of different outcomes |
The guideline committee considered 6 outcomes critical for inclusion in this review: mortality, avoidable adverse events, patient and/or carer satisfaction, quality of life, ED attendance and admission to hospital. The outcome laboratory/diagnostic turnaround for result to a GP was considered important. |
| Trade-off between benefits and harms |
No evidence was identified which compared GP access to same day radiology or ultrasound results with not receiving results the same day. The committee discussed the absence of evidence and decided to develop a research recommendation. The committee noted that, although this is not current practice across the country, there was the potential for improvement in patient care and outcomes from the availability of same day plain x-ray radiology and ultrasound for a specific subset of patients. It may lead to a decrease in ED admissions and earlier diagnosis. In turn, earlier diagnosis could mean quicker treatment and improved patient outcomes, including patient and/or carer satisfaction. Further research would be needed to evaluate this. This could include patients, such as those with asthma, presenting with acute chest pain and the need to rule out a small pneumothorax. The committee accepted that, in general, patients who might benefit from same day results from radiological investigations could be those who might also require specialist investigation or admission to hospital, as opposed to management within primary care; whilst patients with non-acute illness may not require radiology results on the same day. |
| Trade-off between net effects and costs |
No relevant economic evaluations were identified. The unit costs of GP visits, diagnostic tests and relevant hospital admissions or stays were presented to the committee (see Chapter 41 Appendix I). The costs, effectiveness and cost-effectiveness of same day results might be influenced by the equipment used and the type of staff (including the ratio of radiologists to radiographers used in reporting results), Without effectiveness evidence, the committee were unable to assess the cost-effectiveness of same day results and therefore a research recommendation was made. |
| Quality of evidence | No evidence was identified which compared same day GP access to diagnostic radiology results compared to not receiving results on the same day. The committee discussed the absence of evidence and used consensus to develop a research recommendation. |
| Other considerations |
The committee focused the research recommendation on plain x-ray radiology and ultrasound as these investigations were most likely to be of benefit within the community. Ultrasound is included in this recommendation to reflect its growing use in rapid diagnosis, for example, to rule out a pleural effusion. The current approach is for GPs to refer patients to the ED or an AMU if they need same day plain x-ray radiography or ultrasound. Patients would likely prefer rapid diagnosis and management to reduce uncertainty. It would be beneficial to patients to not have to transit through the emergency department to access investigations, particularly to those who are frail or elderly. The group decided not to include more invasive radiological investigations (such as CTPA) within the research recommendation as such patients would likely need specialist review and expert interpretation of results. The committee noted that there were likely to be logistical and staffing difficulties in the provision of same day plain x-ray radiology and ultrasound results. Increased provision of staff training would be required. The committee also noted that a ‘result’ was more than just the radiological images; expert interpretation would also be required for investigations which lay outside the expertise of individual GPs. |
