A new model for general practice-led, regional, community-based, memory clinics



Dementia is a major international health issue with high impact on the patient, relatives, and broader society. Routine screening for dementia is limited, despite known benefit of early detection and intervention on quality of care and patient outcomes. Screening is particularly limited in rural and regional areas, despite high burden and projected growth of dementia in these populations. The current study aimed to implement a new general practitioner (GP) led, multidisciplinary, model of care providing dementia detection and referral pathway to a community-based specialist clinic across six regional general practices.


Cross-sectional analysis of dementia screening and referral characteristics in the St Anthony Family Medical Practices group based in the regional area of Loddon-Mallee, Victoria. Data were collected on demographics and relevant medical history. Cognitive state was assessed using the Mini-Mental State Examination (MMSE), GP Assessment of Cognition (GPCog), and Geriatric Depression Scale (GDS). Referrals and referral outcomes were recorded for geriatrician, psycho-geriatrician, or both.


Eight hundred and eighteenth patients over 65 years were screened, accounting for approximately 24.2% of 65 and over presentations for the practice network. Of those screened, 68.9% were indicated for referral and 30.3% of these were successfully referred. Of the indicated patients who received referrals, 34.2% declined. Many who declined referral had intermediate scores on the cognitive assessments utilized.


Standardised models of care, integrated within community services, are necessary to improve access to early detection, referral and quality management of dementia. The St Anthony Memory Service model will be invaluable in informing future service development, and in particular the development of services for people living with dementia in rural and regional communities.

Peer Review reports

The Known

• Dementia is a major international health issue, which is estimated to affect one in ten Australians over 65, and the prevalence expected to double by 2050

• Despite the positive impact of early detection and intervention on quality of care and patient outcomes, routine screening is limited, particularly in regional and rural communities

The New

• A new model of care, that incorporates training and early dementia detection screening and referral pathway to a community-based specialist clinic, has been implemented and assessed

• Of 818 patients screened, 68.9% were indicated for referral and 30.3% of these were successfully referred. Many who declined referral had intermediate scores on the cognitive assessments utilized

The Implications

• Primary care-based routine screening may help identify early signs of cognitive decline and generate referrals for specialist management

• Further work is needed to target hesitancy in patients with intermediate symptoms


Dementia is a major international health issue with high impact on the patient, relatives, and broader society. In Australia, dementia is a National Health Priority Area with an estimated 386,200 Australians currently living with dementia and with projections of over 800,000 affected by 2058 [1]. Prevalence is greatest in rural and regional areas (1.2% vs 1.1%), with this divide projected to broaden over the coming decades [2]. Increased prevalence in rural and regional areas is thought to relate to the higher prevalence of risk factors such as hypertension, smoking, obesity, type II diabetes, and the higher proportion of people aged over 75 years [3].

Routine screening for dementia is limited, despite known benefit of early detection and intervention on quality of care and patient outcomes, this again particularly evident in regional and rural communities [4]. Dementia healthcare services have become increasingly managed by specialist services, with the World Alzheimer Report 2016 calling for primary and community care services to play a more prominent role in diagnosis and management [5]. The need for timely diagnosis, better diagnostic accuracy, and post-diagnosis management and support is essential for patients and their families [6, 7], and has been reinforced by the recent Australian dementia practice guidelines [8].

General Practitioners (GPs) and Practice Nurses (PNs) are well placed to participate in early, timely dementia diagnosis, and for many patients GPs are the first point of contact when symptoms present [9,10,11]. Despite this, up to 65% of people who were found to have cognitive deficits on standardized testing in American primary care had not been previously considered to have dementia by their treating medical practitioners [12].

Memory clinics are specialised, collaborative services with streamlined diagnostic and post-diagnostic support pathways [13]. The majority of memory clinics are based in tertiary-hospitals and metropolitan areas. Memory clinic capacity is also limited, with most patients referred receiving one or two appointments before being discharged to GPs who have limited specialist training in management of people with cognitive impairment [13]. A review by Greenway-Crombie, Snow et. al. [14] highlighted the barriers to dementia diagnosis in rural general practice, which include a lack of specialist dementia support, stigma and negativity, diagnostic uncertainty and disclosure, lack of dementia-specific training, and the service complexity.

While the iterative process of GP education is essential, many GPs indicate a desire for specialist consultation in the areas of dementia diagnosis and management [15]. In Australia the need for referral is reinforced by the current prescription regulations which only allow for a pharmaceutical benefits scheme subsidy for dementia-specific medications if the initial prescription was by a medical specialist (eg geriatrician, neurologist or psychiatrist) or by a GP in consultation with such a specialist [16].

The program described in this paper sought to increase GP access to specialist advice, both through the co-location of a geriatrician and psycho-geriatrician specialists consulting within the primary setting, and through informal as-needed dialogue either in person or on the telephone. The program was also planned to remove barriers to patient attendance for dementia screening, by locating this within the general practice location, which was familiar and provided adequate free parking, and with no financial disincentive by funding specialist consultations through the Medicare program. The new model of care described in this paper was developed in a multi-site regional and rural general practice and aims to incorporate training and the use of standardised tools within primary care to address the limited access to screening and management of dementia in the community setting.


Study setting and sample

St Anthony Family Medical Practices P/L (SAFMP) are general practice-based group in the rural and regional, Loddon-Mallee region of Victoria, Australia. The area has a catchment of 12,213 km2 with 58,602 persons aged over 65 years, equivalent to 18.5% of the total population [17]. The SAFMP group encompassed seven practices, employing 48 general clinicians and providing 3,386 encounters for patients aged over 65 each year (2015 practice data).

Model design: GP-Led early detection of cognitive impairment

To address access for people with cognitive impairment living in regional Victoria, a community-based high-quality diagnostic and management service model was developed. This included the education of GPs and PNs and the development of an early dementia detection screening and referral pathway to a community-based specialist clinic, the St Anthony Memory Service (Table 1).

Table 1 Model components

The model included: 1) the education of GPs and PNs; 2) the development of an early dementia detection screening and referral pathway; 3) provide access to a specialist cognitive assessment service based in the practice community; 4) raise awareness in the practice community about dementia and dementia risk management strategies; and 5) collect a body of patient data from initial screening through to cognitive assessment outcomes.

Staff training

All practice group staff underwent a one-day training program in the delivery of cognitive assessments; including education on: recognising dementia in general practice; risk factors and management; use of treatments – pharmacological and non-pharmacological; behavioural and psychological symptoms of dementia (BPSD) and depression; caregiver stress, support services and respite; legal issues; end of life management, advanced directives and palliative care. Individual practices were offered support to provide community information sessions on the initiative, and on dementia and dementia risk minimization. An information sheet about dementia and the initiative was developed and placed in practice waiting rooms and given to those who underwent screening. GPs who attended voiced an increase in approaching people aged over 65 in regards to cognition screening as well as an increased confidence in the management of dementia in the primary care setting.

Cognitive assessment process

Cognitive assessment was undertaken on all patients aged over 65 years who attended the GP practices, as well as patients who expressed concern regarding cognitive deficits, or patients who had concerns raised by an associated family member or caregiver. Practice nurses held an integral part of the process, doing the cognitive assessments and forming an essential part of the therapeutic relationship. Practice nurse screening often formed part of a routine 75 + assessment carried out by the nurses in the course of their usual practice. The assessment process consisted of: clinical and neurological examination by the GP; basic blood tests including full blood count, renal and hepatic function tests, assessment for diabetes, thyroid function, vitamin B12 and folate; brain CT scan; and cognitive assessment using Mini-Mental State Examination (MMSE) [18], GP Assessment of Cognition (GPCog) [19], and Geriatric Depression Scale (GDS) [20]. All participants with GPCog score of ≤ 9, and/or GDS ≥ 6 and/or MMSE ≤ 24 and/or those about whom the GP or PN was concerned, were referred to the project geriatrician or psycho-geriatrician (Table 2). The specialist service was based on a rapid response with no referred person waiting more than 4 weeks, and most seen within 2 weeks. Referral to other services included but was not limited to neuropsychologist, physiotherapy, occupational therapy and social work, and was done on an as needs basis as determined through the assessment.

Data collection

Data was collected on all people screened between 2014 to 2018. Data collected included demographics, SEIFA (Socio-Economic Indexes For Areas) rank [21], medical history, smoking status, referral status and outcome, as well as GDS, GPCog, and MMSE scores.

Statistical methods and data analysis

Data analysis was performed using SPSS statistical software version 26.0 (IBM Corp, Armonk, NY, USA). Patient demographics, medical history, and outcome scores are reported descriptively. Descriptive data is presented as mean and SD unless stated otherwise.


Patient demographics

From the implementation of the model in 2014 to March 2017, 818 patients aged over 65 years were screened, accounting for approximately 24.2% of 65 and over encounters for the practice network (Table 3). Those screened had a mean age of 77.37 years (7.495 SD) and 51.1% (418) were female. The population was otherwise relatively homogenous, mainly born in Australia (611, 88.6%) and English speaking (> 99%). A third (275, 34.4%) noted that they lived alone.

Table 3 Patient demographics

Comprehensive relevant medical history was obtained in the majority of patients reviewed (Table 4). Three quarters (598, 75.4%) had a history of cardiovascular disease and half (431, 53.3%) were on statin therapy. Depression or anxiety and antidepressant use was reported in one in five patients. The majority (598, 90.1%) had no reported family history of dementia. One in ten had a history or stroke, brain, or head injury of various aetiology.

Table 4 Patient medical history

Cognitive assessment

GDS was suggestive or indicative of depression in 13.8% of patients screened (Table 5). As expected, GDS suggestive of depression was significantly associated with formal diagnosis of depression (p < 0.001) and use of antidepressants (p < 0.001), but was also associated with a history of stroke, brain, or other head injury (p < 0.001), current smoker status (p < 0.001), and use of sleeping tablets (p = 0.004). Half (453, 55.9%) of patients screened using GPCog required additional testing to determine cognitive impairment whilst one in ten (82, 10.1%) had symptoms indicative of impairment. GPCog score indicating referral was significantly associated with diagnoses of depression or anxiety (p = 0.008) and use of antidepressants (p = 0.003). The majority (606, 87.4%) of patients showed no symptoms consistent with dementia on the MMSE outcome. MMSE scores indicative of dementia were significantly more frequent in men (p = 0.026) and people with diabetes (p = 0.042).

Table 5 Cognitive assessment scores

Referral rates

Of the 818 screened using at least one assessment tool, 564 satisfied the criteria for referral to a geriatrician and/or psycho-geriatrician as per the referral guide (Table 6), and 30.3% of these were successfully referred. Over half of the people who satisfied referral criteria (302, 53.5%) were not referred, and of the 260 patients referred, a third (89, 34.2% of referred patients) declined a specialist appointment. Of the 302 people who were not referred, the majority (273, 90.4%) had GPCog scores categorised as ‘more information required’. Similarly, most who were considered appropriate but declined referral (66, 74.2%) had GPCog scores categorised as ‘more information required’.

Table 6 Eligibility and actual referrals


The National Framework for Action on Dementia 2015–2019 [22] highlights the challenges that people with cognitive impairment face in rural and regional areas in accessing appropriate medical management, including access to primary and specialist medical care. The current study was successful in conducting validated screening tests on one in four patients aged over 65 who presented at the St Anthony Family Medical Practices, the majority of whom were unlikely to be formally assessed prior to the program. Of those screened, two-thirds (68.9%) warranted further specialist investigation. These results highlight the opportunity of GPs to initiate early screening and intervention and are consistent with the National Framework emphasis on timely diagnosis and flexible modes of delivery [22]

Primary care in Australia is increasingly taking on a greater role in both the assessment and the long term care of people with dementia and a multicenter randomised controlled trial found no evidence that specialist memory clinics were more effective than general practice services in providing post-diagnostic support [23]. Secondary referral services, however, do have a critical role in defining the dementia subtype, dealing with more complex cases, and stratifying which patients with mild cognitive impairment are at greatest risk of developing dementia and most in need of follow-up. The primary motivation for developing the program described in this paper was to improve the local services for people with cognitive deficits, through encouraging the early identification of dementia and mild cognitive impairment by GP services and increasing access to specialist assessment for optimal management in the hope of modifying the progression of this through improved diagnosis, lifestyle changes and medication where appropriate.

Positive screening in the current study resulted in 171 successful referrals to a geriatrician and/or psycho-geriatrician. Nevertheless, it was disappointing that over half of the people who satisfied referral criteria were not referred, and a third of referred patients declined a specialist appointment. The majority of those who were either not referred, or declined a referral, had returned intermediate scores on the GPCog assessment which indicated a need for further assessment but did not necessarily indicate dementia. When compared to the MMSE, the GPCog has been shown to have increased sensitivity [24]. A study of 3750 geriatric patients previously identified 68% as requiring further testing, and of those 49% went on to have a diagnosable dementia [25]. Of the ‘false positives’ in that study, 38% showed signs of definitive cognitive impairment that did not meet diagnostic criteria [25]. These findings suggest that those with mild signs of impairment are most likely to be deemed as not requiring further care as well as more likely to reject specialist support. Efficacy of office-based screening for early dementia has indeed been called into question given limited treatment options and the likelihood of false positives causing unnecessary distress for patients [26]. Although referral rates in the current study are indicative of barriers to acceptance from either GPs or patients themselves which elicits further research on improving acceptability, the use of GPCog in general practice settings represents a valuable opportunity to detect and monitor cognitive impairment in geriatric populations.

Several factors drove the impetus for the development of this program, including informal discussions with local GPs which drew attention to the difficulties they faced in managing people with cognitive impairment, including limited confidence in the diagnosis of dementia and with disclosing the diagnosis to affected people and their family [15]. Practitioners reported difficulties in the referral process of affected people in this regional area, which had only one Memory Clinic with limited resources, and also noted reluctance of affected people to undergo specialist review for a problem that they were often reluctant to acknowledge as such [15].

These barriers are not unique to the target practice but have been echoed in broader regional and rural communities. Koch and Iliffe [6] reported that many barriers exist at the patient, doctor, and system level for a timely diagnosis, including the eradication of dementia-associated stigma in order to improve the early detection and management of dementia, while Bradford et. al. [7] identified issues with attitudes and patient-provider communication, educational deficits, and system resource constraints as major contributory factors.

A limitation of this program was that people who attend this practice form a relatively homogenous group, mostly born in Australia and English speaking, which is consistent with the demographics of regional Victoria. Whether the program would have been as acceptable to people of a more diverse ethnic background needs to be explored further in other settings if a program such as this is to be replicated across other primary health care settings. In addition, the long-term benefits of early detection and management of people with mild cognitive impairment and dementia also needs to be investigated in the long term in parallel to upscaling the capacity of the Australian health system to manage the increased demand.


Dementia screening can be offered to all patients aged 65 and over in rural settings when integrated as a model of GP-led screening with referral pathways to community-based specialist services. Implementation of standardised processes and practitioner training markedly improved early screening and referral for patients with cognitive change. This new, innovative model of care is scalable across health systems with potential to address geographical barriers through online screening and engagement. Future research should aim to explore interventions to support management of cognitive impairment for people living with dementia in the rural setting.
