Geographic variation in referral practices for patients with suspected head and neck cancer: A survey of general practitioners using a clinical vignette.

Introduction: General practitioners (GPs) play a crucial role in cancer care and GPs are often the first doctor that patients with symptoms suggestive of cancer will encounter. Head and neck cancer (HNC) is a relatively uncommon presentation in primary care, and evidence suggests that times to diagnosis and treatment of HNC vary based on geographical location of patients. This may be due to barriers to referral faced by regional or rural GPs as compared to those in metropolitan cities in Australia. Objective: To investigate the effect of geographical location of GPs on management of patients with symptoms suggestive of HNC. Design: This was a descriptive, analytical, cross‐sectional survey. Surveys were sent to GPs at practices in two primary health care networks in New South Wales, Australia (Mid North Coast Primary Healthcare Network and the Central and Eastern Sydney Primary Healthcare Network) between February and May 2020. Main outcome measures were perceived time from referral to specialist appointment, factors affecting timeliness of patient help‐seeking, and awareness and use of clinical guidelines. Findings: A total of 1803 GPs were sampled, of which 196 responded (45 regional GPs and 151 metropolitan GPs). Less than half (48%) of regional GPs reported patients could expect to be seen by a specialist within 2 weeks of referral, compared to 70% of metropolitan GPs (p = 0.001). Most metropolitan GPs stated they would refer a patient with suspected HNC to a surgeon subspecialising in HNC. Regional GPs were split between ear, nose, and throat (ENT) and general surgeons. Availability of services was the most common factor influencing referral practices for regional GPs, whereas for metropolitan GPs, this was the patient's symptoms. Awareness of government resources for cancer referrals was generally low. Discussion: Regional GPs report patients with HNC are less likely to be seen by a specialist within optimal time frames compared to metropolitan GPs. Respondents reported different barriers to early referral of patients with suspected HNC, with regional GPs more often citing system‐level factors while metropolitan GPs more often cited patient‐level factors. Conclusion: Evaluating service provision and uptake with respect to community need, and addressing of barriers to implementation, may minimise unwarranted clinical variation. [ABSTRACT FROM AUTHOR]
