GP-patient communication about possible cancer in primary care: Re-evaluating GP as gatekeeper

Why clinicians overtest: development of a thematic framework

BACKGROUND

Medical tests provide important information to guide clinical management. Overtesting, however, may cause harm to patients and the healthcare system, including through misdiagnosis, false positives, false negatives and overdiagnosis. Clinicians are ultimately responsible for test requests, and are therefore ideally positioned to prevent overtesting and its unintended consequences. Through this narrative literature review and workshop discussion with experts at the Preventing Overdiagnosis Conference (Sydney, 2019), we aimed to identify and establish a thematic framework of factors that influence clinicians to request non-recommended and unnecessary tests.

METHODS

Articles exploring factors affecting clinician test ordering behaviour were identified through a systematic search of MedLine in April 2019, forward and backward citation searches and content experts. Two authors screened abstract titles and abstracts, and two authors screened full text for inclusion. Identified factors were categorised into a preliminary framework which was subsequently presented at the PODC for iterative development.

RESULTS

The MedLine search yielded 542 articles; 55 were included. Another 10 articles identified by forward-backward citation and content experts were included, resulting in 65 articles in total. Following small group discussion with workshop participants, a revised thematic framework of factors was developed: "Intrapersonal" - fear of malpractice and litigation; clinician knowledge and understanding; intolerance of uncertainty and risk aversion; cognitive biases and experiences; sense of medical obligation "Interpersonal" - pressure from patients and doctor-patient relationship; pressure from colleagues and medical culture; "Environment/context" - guidelines, protocols and policies; financial incentives and ownership of tests; time constraints, physical vulnerabilities and language barriers; availability and ease of access to tests; pre-emptive testing to facilitate subsequent care; contemporary medical practice and new technology CONCLUSION: This thematic framework may raise awareness of overtesting and prompt clinicians to change their test request behaviour. The development of a scale to assess clinician knowledge, attitudes and practices is planned to allow evaluation of clinician-targeted interventions to reduce overtesting.

Exploring public attitudes towards the new Faster Diagnosis Standard for cancer: a focus group study with the UK public

Background

The Faster Diagnosis Standard (FDS) is to be introduced in England in 2020. This standard is a new policy in which patients should have cancer ruled out or diagnosed within 28 days of referral.

Aim

To explore public attitudes towards the FDS within the context of their recent referral experiences.

Design and setting

Four 90-minute focus groups (two in Guildford, two in Bradford).

Method

Participants aged >50 years without a current cancer diagnosis (N = 29), who had completed certain diagnostic tests, for example, ultrasound, and received results within the last 6 months were recruited. Age, education, and sex were evenly distributed across groups through purposive sampling.

Results

The largest cause of concern was the waiting process for obtaining test results. Most had experienced swift referral, and it was difficult for participants to understand how the new standard could impact upon time progressing through the system. Responsibility for meeting the standard was also a concern: participants did not see their own behaviours as a form of involvement. The GP’s role was conceptualised by patients as communicating about their referral, establishing patients’ preferences for information, and continued involvement at each stage of the referral process. The standard legitimised chasing for test results, but 28 days was considered too long.

Conclusion

Patients should be asked what they would like to know about their referral. GPs should be more transparent about the referral process and the potential for a lack of clarity around next steps.
