Conceptual Framework for Dementia Burden, Healthcare Worker Competence, Health System Capacity, and Family Caregiving Experiences

2.1. Framework development approach

A mixed-methods study carried out in the OR Tambo District in the Eastern Cape, South Africa, developed the conceptual framework. Using established tools, the quantitative component evaluated the burden of dementia symptoms, healthcare workers’ knowledge and skills, and the health system’s preparedness. Through in-depth interviews, the qualitative component examined the lived experiences of family caregivers. The framework’s dimensions, mediating factors, and outcomes were determined through an integration of quantitative and qualitative research.

2.2. Theoretical foundations underpinning the framework

2.2.1 Biopsychosocial model

The Biopsychosocial Model⁷ informs the conceptual framework, recognising dementia as a complex disorder shaped by the interaction of biological, psychological, and social elements. This conceptual framework gives a comprehensive view of dementia and emphasises the importance of integrated, person-centred, and interdisciplinary dementia care approaches.

Within the framework, dementia is viewed as more than just a neurological condition impacting memory and cognition. Instead, it is viewed as a complex disorder that affects the physical health, emotional well-being, social interactions, and daily functioning of both dementia patients and their caregivers.

The framework recognises dementia as influenced by:

Biological factors include cognitive decline, memory impairment, neurological deterioration, behavioural symptoms, ageing, and chronic disease comorbidities like hypertension and diabetes.²² Psychological factors include emotional distress, anxiety, depression, dementia symptoms, carer stress, burnout, and coping responses. Social factors include family dynamics, caregiving responsibilities, poverty, and stigma.

The Biopsychosocial Model reinforces the framework’s emphasis on integrated dementia management by recognising that effective care must address not only clinical symptoms, but also psychological well-being, carer experiences, and larger social determinants of health. The framework emphasises the role of interdisciplinary teamwork, carer support, community awareness, and health system strengthening in improving dementia outcomes.

Using this theoretical approach, the framework views dementia care as a shared obligation amongst healthcare systems, families, communities, and social support structures, all working together to protect dignity, improve quality of life, and minimise the overall burden of dementia.

2.2.2. Person-centred care theory

The framework prioritises person-centred values in dementia care, such as patient dignity, respectful communication, personalised care, emotional support, and meaningful participation.⁸ These principles recognise that people with dementia have unique needs, beliefs, preferences, and lived experiences. The approach highlights the importance of compassionate relationships, protection of autonomy, and psychosocial health in dementia care, in addition to symptom control. Respectful communication and emotional support build trust among healthcare personnel, carers, and patients, while meaningful participation promotes identity, social connection, and quality of life. Individualised care also ensures that therapies are matched to the cognitive, emotional, behavioural, and cultural needs of everyone with dementia.

2.2.3. Social ecological theory

The conceptual framework also incorporates the Socioecological Model, which acknowledges that dementia care is influenced by numerous interacting layers of society. This viewpoint recognises that the experiences and results of people living with dementia and their caregivers are influenced by family ties, community surroundings, healthcare systems, and broader policy structures.⁹

Within the framework, dementia care is thus conceptualised as occurring across interconnected levels:

3.1. Significant components of conceptual framework

The framework involves five interconnected domains (see Table 1):

These dimensions interact continuously, influencing dementia care experiences and outcomes.

3.2. Domain one: dementia clinical burden

The person with dementia is at the centre of the conceptual framework, with various interconnected cognitive, behavioural, psychosocial, and physical health issues. Memory loss, short-term memory impairment, behavioural abnormalities, delusions, communication difficulties, and chronic disease comorbidity were among the most common clinical symptoms reported in the study. The existing literature supports that dementia is a heterogeneous and progressive disorder characterised by severe cognitive decline, neuropsychiatric symptoms, and functional reliance.^10,11 stressed the rapid dementia symptoms demonstrate the complicated and progressive nature of dementia, as well as its significant influence on everyday functioning and quality of life.

The quantitative results showed that dementia symptoms were consistently severe across all age and gender groups. Almost all participants reported short-term memory loss and behavioural abnormalities, with a significant number also reporting communication difficulties and co-existing chronic illnesses such as hypertension, diabetes, and other age-related conditions. These findings indicate that dementia is not perceived as an isolated cognitive impairment in South Africa.¹² aligned with the above findings that dementia is understood as a multifaceted condition that necessitates extensive and continuous therapy.

Within the conceptual framework, dementia is thus viewed as a multidimensional condition that affects cognitive, emotional, behavioural, and physical functioning. It is a progressive cognitive disorder with a gradual decline in memory and executive functioning, as well as behavioural and psychological symptoms like agitation, confusion, aggression, and delusions.¹³ Dementia is also complicated by multimorbidity and chronic disease burden, and requires long-term, integrated, and person-centred care.¹⁴

The framework also suggests that the severity and persistence of dementia symptoms are closely linked to several negative outcomes. These include increased functional dependence among dementia patients, higher carer load, increased healthcare use, emotional and psychological suffering in families, and an increased risk of stigma, social isolation, neglect, and poor care quality.¹⁵ highlight that as dementia advances, the interplay of cognitive decline and chronic disease comorbidity increases care needs for both families and healthcare systems. The current study underscores the need for early diagnosis, continuous clinical monitoring, integrated chronic disease management, and psychosocial support interventions to reduce the overall clinical burden of dementia and improve the well-being of both patients and caregivers.¹⁶ Early detection of dementia is recommended as on strategies to ensure clinical monitoring of dementia progression.

3.3. Domain two: healthcare worker knowledge and competence

Knowledge and competence of healthcare workers play an important role in the conceptual framework for dementia Burden, Healthcare Worker Competence, Health System Capacity, and Family Caregiving Experiences. The ability of healthcare personnel to detect, assess, manage, and support people with dementia has a substantial impact on the quality, effectiveness, and continuity of care delivered in various healthcare settings.¹⁷

The quantitative findings suggested that most healthcare staff had only a moderate understanding of dementia. There were significant misconceptions about the causes, course, and management of dementia, with some healthcare staff mistaking dementia symptoms for normal ageing or other mental health issues. Previous research has found that healthcare personnel frequently lack dementia-specific expertise, notably in terms of early detection, behavioural signs, and differential diagnosis.¹⁸ According to,¹⁹ many primary healthcare personnel lacked a thorough understanding of dementia symptom progression and management, which contributed to delayed recognition and treatment.

Furthermore, the data showed that healthcare workers had moderate general competency in dementia care, as well as inadequate formal mental health and geriatric training.²⁰ Inadequate dementia training among healthcare staff leads to poor communication, ineffective behavioural management, and bad attitudes toward people with dementia. Hospital-based healthcare personnel indicated higher levels of competence than those working in primary care and community settings, probably due to increased exposure to specialised services and interdisciplinary assistance. Previous research supports this finding,²¹ demonstrating that healthcare personnel in tertiary and specialist settings often report greater dementia care competence due to greater access to interdisciplinary collaboration, continued professional development, and clinical supervision.

Within the framework, dementia knowledge is viewed as a fundamental variable that influences numerous key areas of dementia care.

Adequate dementia knowledge improves:

To effectively manage dementia, it’s important to recognise symptoms, assess cognitive loss, provide appropriate referrals, communicate effectively with carers and family, and distinguish between dementia and other psychiatric problems.

Similarly, dementia care competence is viewed as influencing the practical provision of quality care. Higher levels of competence lead to:

Improved patient interaction, effective management of behavioural and psychological symptoms, person-centred care, patient dignity and autonomy, carer education and support, and collaborative dementia management.

The framework also suggests that low levels of healthcare workers’ knowledge and competence contribute directly to various systemic issues in dementia care. These include delayed diagnosis, stigma and discriminatory attitudes in hospital settings, poor communication with caregivers. An insufficient management of behavioural symptoms, fragmented care coordination, and lower overall quality dementia care services.²²

3.4. Domain three: health system and service capacity

The structural and organisational environment in which dementia care is administered is defined by health system capability.²³ As a result,²⁴ supports the notion that the availability, accessibility, coordination, and quality of healthcare services and support systems significantly impact the effectiveness of dementia management. The study’s findings found significant gaps in dementia-related service provision, indicating fundamental systemic impediments that affect both dementia patients and carers.

The study identified several significant gaps in the healthcare system, including a shortage of dementia specialists, limited carer support programs, insufficient community awareness initiatives, insufficient dementia-specific training for healthcare workers, limited access to assistive technologies, limited support groups, and insufficient respite care services for carers. These restrictions together hinder the healthcare system’s ability to deliver comprehensive, continuous, and person-centred dementia care.

Despite these issues, several strengths in the healthcare system have been highlighted. These included interdisciplinary healthcare teams in specific facilities, structured care environments, and access to counselling and psychosocial support services in some healthcare settings. These existing tools serve as a basis for improving and expanding more integrated dementia care services.

Within the conceptual framework, health system capacity is conceptualised through two interrelated dimensions: Structural factors and Service delivery factors.²⁵

3.5. Domain four: caregiver and community experiences

The conceptual framework acknowledges family carers as key stakeholders in dementia care.

The qualitative findings revealed seven important themes that influence carer experiences:

Caregivers’ emotional distress was made worse by dementia-related behavioural and psychological symptoms such as hostility, wandering, confusion, agitation, and delusions. Many carers reported a lack of emotional support or respite, putting them at risk for mental health issues. According to the framework, carer well-being is a significant predictor of long-term dementia care. Caregivers reported negative community reactions, including allegations of witchcraft, shame, violence, public humiliation, and social exclusion directed at people with dementia and their families. Misunderstandings about dementia in communities contributed to discrimination and delayed help-seeking behaviours.

Caregivers recommended practical improvements to improve dementia care services and alleviate carer burden. Suggested interventions include:

Services for individuals with dementia include dementia-aware clinics, priority queuing at healthcare facilities, home visits and outreach, community education programs, financial aid, transportation support, carer training, and safe day-care and respite spaces.

3.6. Domain five: dementia care outcomes

The framework outlines three types of results (Table 2):

3.7. Mediating factors

The framework identifies several mediating elements that affect the links between independent domains and outcomes (see Table 3). Increased care needs and dependency, to reduce the dementia clinical burdens. The person-centred care methods, and the quality of dementia care are examples of healthcare service factors. Social support and coping mechanisms are examples of caregiver adaptation factors. Access to services is one of the elements that affect healthcare access. Healthcare Worker competence (empathy, respect, knowledge, responsiveness, non-stigmatising behaviour) is an example of professional behaviour factors. Community awareness of dementia is one aspect of the communal environment.

3.8. Interaction between domains

According to the conceptual framework, ongoing domain interactions shape dementia outcomes (see Table 4). Caregiver and community experiences shape caregiving resilience and social support; healthcare worker competence influences diagnosis and care quality; health system capacity determines access to and continuity of services; dementia’s clinical burden increases care needs and dependency; and community attitudes influence stigma, safety, and inclusion.

As it pertains to the conceptual framework, caregivers are more burdened when the healthcare system is unprepared; stigma is exacerbated by a lack of knowledge about dementia; behavioural symptoms increase emotional work; social isolation and conflict in the community are exacerbated by stigma; moral harm is increased by inadequate services; and integrative support systems enhance dignity and quality of life.

4.1. Implications of framework

The framework highlights the need for:

4.2. Significance of the conceptual framework

This conceptual framework is important because it offers a clear understanding of the factors that affect dementia management. It can help researchers, healthcare workers, policymakers, and caregivers in creating programs to improve patients’ dementia well-being and develop dementia management strategies.

The framework also emphasises the need for continuous dementia workshops for healthcare workers, psychosocial support for families, caregiver training for caregivers, building resilience, and culturally sensitive interventions for everyone. Findings based on this conceptual framework may aid in developing community support programs, healthcare policies, and mental health interventions for dementia management.
