Unburdening dementia – a basic social process grounded theory based on a primary care physician survey from 25 countries

Abstract

Objective

To explore dementia management from a primary care physician perspective.

Design

One-page seven-item multiple choice questionnaire; free text space for every item; final narrative question of a dementia case story. Inductive explorative grounded theory analysis. Derived results in cluster analyses. Appropriateness of dementia drugs assessed by tertiary care specialist.

Setting

Twenty-five European General Practice Research Network member countries.

Subjects

Four hundred and forty-five key informant primary care physician respondents of which 106 presented 155 case stories.

Main outcome measures

Processes and typologies of dementia management. Proportion of case stories with drug treatment and treatment according to guidelines.

Results

Unburdening dementia – a basic social process – explained physicians’ dementia management according to a grounded theory analysis using both qualitative and quantitative data. Unburdening starts with Recognizing the dementia burden by Burden Identification and Burden Assessment followed by Burden Relief. Drugs to relieve the dementia burden were reported for 130 of 155 patients; acetylcholinesterase inhibitors or memantine treatment in 89 of 155 patients – 60% appropriate according to guidelines and 40% outside of guidelines. More Central and Northern primary care physicians were allowed to prescribe, and more were engaged in dementia management than Eastern and Mediterranean physicians according to cluster analyses. Physicians typically identified and assessed the dementia burden and then tried to relieve it, commonly by drug prescriptions, but also by community health and home help services, mentioned in more than half of the case stories.

Conclusions

Primary care physician dementia management was explained by an Unburdening process with the goal to relieve the dementia burden, mainly by drugs often prescribed outside of guideline indications.

Implications: Unique data about dementia management by European primary care physicians to inform appropriate stakeholders.

Key points

• Dementia as a syndrome of cognitive and functional decline and behavioural and psychological symptoms causes a tremendous burden on patients, their families, and society.

• •We found that a basic social process of Unburdening dementia explained dementia management according to case stories and survey comments from primary care physicians in 25 countries.

• •First, Burden Recognition by Identification and Assessment and then Burden Relief – often by drugs.

• •Prescribing physicians repeatedly broadened guideline indications for dementia drugs. The more physicians were allowed to prescribe dementia drugs, the more they were responsible for the dementia work-up.

• Our study provides unique data about dementia management in European primary care for the benefit of national and international stakeholders.

Introduction

Dementia arises together with the accumulation of harms and disease burdens over the life course, and clusters with other endemic conditions exacerbating each other synergistically [1,2]. Multimorbidity and cardiovascular comorbidity show prevalences of 65–98% for those more than 65 years of age [3] with accompanying polypharmacy and potentially inappropiate medications adding to the burdens [4]. Dementia can be seen as a triad of impairments and burdens: cognitive, emotional, and physical [2] in a ‘frail brain’ [5]. Dementia eventually results in disabled instrumental and basic activities of daily life, neuropsychiatric issues, personality changes, social impairment and stigma [6]. These disease burdens are often long lasting and indeed affect family caregivers who often develop depression and physical illnesses while caring for their loved ones [7]. A systematic review dominated by qualitative studies of dementia management in primary care showed lack of support for patients, caregivers and primary care physicians and an attitude of ‘therapeutic nihilism’ [8]. There was also limited access to and knowledge about community services and resources and absence of interdisciplinary teams to enhance management [8]. Other main themes from the qualitative studies were ‘time constraints, financial constraints, stigma, diagnostic uncertainty, and disclosing the diagnosis’ [8]. With this gloomy review as background, we wanted to explore dementia management using an inductive approach from classic grounded theory where the basic research question is ‘what is going on?’ We wanted to know how primary care physicians in different countries treat their patients suffering from dementia, and to generate an explanatory theory of dementia management in primary care.

Methods

Study design

For this survey study directed to primary care physicians in 25 countries of the European General Practice Research Network (EGPRN), we developed a seven-item multiple choice questionnaire (MCQ). The design of the survey has been presented elsewhere [9,10]. At the end of every MCQ, optional free text comments could be added [10]. In the eighth and last survey item, we invited respondents to contribute anonymised case stories of dementia from their own practice.

We applied an analytic classic grounded theory approach characterised by inductive reasoning with no a priori hypotheses allowing both qualitative and quantitative data analysis [11–13].

Setting

In the 25 countries, national key informants were identified and contacted face to face by author FP during meetings of the EGPRN and WONCA Europe conferences in 2013–2015. National key informants organised translation of the survey into their own languages and back translation to English. They also selected further key informants from different geographical and socio-economic regions within their country by convenience or snowball sampling.

Participants and data

445 key informant primary care physicians from 25 countries, of which 106 physicians from 23 countries presented 155 case stories.

Data coded for this study:

1. Secondary analysis of MCQ data provided by 445 key informants and 8,000 words of free text data from the same survey [9,10].

2. Data from 106  key informants who provided 155 case stories consisting of 40,000 words.

Grounded theory analysis

Classic grounded theory is the world’s most cited behavioral research method with 124,055 Google Scholar citations (15 July 2020) [11]. In classic grounded theory, hypotheses are inductively generated to explain how participants resolve their main concern abstract of time, place and people [11,13,14]. Classic grounded theory differs from other methods using only qualitative data by emphasising explanatory concepts rather than descriptions.

Theoretical memos, in the shapes of text, diagrams, and figures, were written, typed, or drawn to create a 200-page memo bank from which this paper was written. ‘Memos are the theorizing write-up of ideas about substantive codes and their theoretically coded relationships as they emerge during coding, collecting and analysing data’ [14]. These memos were analysed based on grounded theory quality principles of fit, relevance, workability and modifiability [14,16]. Then followed selective coding where the core concept guided the analysis during theoretical memoing. We coded case stories and survey text comments asking for each incident in the data ‘What is the participants’ main concern and how is it being resolved?’ and ‘What are the participants doing to resolve their main concern’ and ‘What is this a study about?’. Answers to these coding questions yielded several hundred indicators of preliminary dementia discovery, diagnosis, work up and treatment. Theoretical memos included codes related to care and caregivers – spouse, children, institutional and non-institutional care etc. We further analysed survey free text including descriptions of formal and informal rules of dementia work up and diagnostic and treatment structures of the jurisdiction in which the case story took place [9].

The core concept was theoretically coded using a basic social process [11,14–16] to explain the ongoing resolution of the main concern in the case stories.

We also ran numerous statistical analyses based on both grounded theory codes and results of MCQ questions. These analyses were included in memos to deductively fit the emerging concepts by applying the ‘constant comparative method’ of grounded theory and indeed using its dictum ‘all is data’ [14,16].

The grounded theory analysis was mainly done by the first and last author in collaboration and analytic consensus was reached during the write-up process lasting several years and ending with the submission of this manuscript. Good grounded theories should indeed be modifiable when new data enters such as relevant critique from reviewers [14,16].

Dementia analysis

Proxies for treatment appropriateness were aligned with the guidelines for dementia drug therapy and established by a tertiary care physician researcher expert on neurocognitive disorders (author SP) [17,18]. SP also assessed the specific dementia type based on the information given in the case stories in accordance with the DSM-5 [19].

Statistical analysis

IBM SPSS Statistics for Windows, Version 22.0. (IBM, Armonk, NY USA, 2013) was used for descriptive and exploratory statistical analyses. Cluster analysis is an exploratory method used to identify structures within the data such as homogenous groups of cases if grouping and differences between dependent and independent variables is previously unknown [10,20]. We did two-step cluster analyses with variables emerging from memos. Overall goodness-of-fit of clusters had silhouette coefficients with measures of less than 0.2 classified as poor, between 0.2 and 0.5 fair, and more than 0.5 as a good solution quality. Fair or higher was considered acceptable clustering with a cut-off score at 0.3 [20]. More advanced statistical methods such as Directed Acyclical Graphs were applied to the data in another version of this study available online [10].

In summary, this study involved a mix of data and methods emphasising an inductive approach of classic grounded theory with the goal of exploring and generating a hypothesis of what was going on in the field of primary care physician dementia management.

Results

A multitude of burdens was the main concern surrounding the care of patients with dementia and their caregivers. Patients and caregivers were overwhelmed not only by the burden of dementia but often by multimorbidity – present in 74% of the case stories – and by behavioural and psychological symptoms of dementia.

The core concept, Unburdening dementia, was deduced as a label explaining the resolution of the main concern.

Unburdening dementia is seen as a basic social process starting with Identifying the burden, mostly done by family members of the patient, then Assessing the burden by cognitive tests, especially the Mini Mental State Examination (MMSE), the most used cognitive psychometric test internationally [21]. The dementia burden is then Recognised by formal caregivers and eventually pursued by Burden Relief, often by prescription drugs in 130 of 155 (84%) of the cases but also by community health and home help services, mentioned in more than half of the case stories. The basic social process of Unburdening dementia is presented in Table 1 with sub-categories and different properties.

Table 1. The basic social process of Unburdening Dementia.*

Unburdening Dementia - a two-step Basic Social Process
BASIC SOCIAL PROCESS STAGE:	Recognising burden after burden identification and assessment.	Burden Relief
APPLIED TO DEMENTIA CARE :	Identifying cognitive and mental burden by family caregiver. Assessing burden by psychometric tools and then Recognising burden by formal caregiver.	Cognitive, mental and social Burden Relief
CASE STORY ILLUSTRATION:	Consultation together: spouse/child report memory loss. Physician notices lack of collaboration during consultation. Assessment with Mini Mental State Examination.

The table illustrates the basic social process of Unburdening Dementia that emerged to explain the action in the data provided by primary care physicians across EGPRN countries. *Basic social processes are grounded theory core variables that are ‘processural’ meaning that they have two or more clear emergent stages [13,14]. Descriptive incidents of community health and home help services (such as nursing home care and dementia services) appeared in more than half of the case stories as indicators of a property of Burden Relief.

Unburdening explains what many physicians – both primary care physicians and secondary care specialists – were doing to help patients and their families. Unburdening often resulted in Burden Relief consisting of drug prescriptions – the most available therapeutic tool. Acetylcholinesterase inhibitors or memantine treatment was reported in 89 of 155 patients (57%): 60% of the prescriptions were appropriate according to guidelines and 40% prescribed outside of guidelines. Antidepressants were mentioned in 27% of the patients, and to a lesser degree other drugs such as antipsychotics. Only 22 out of 155 case stories did not mention any drug to relieve the dementia burden. More than two-thirds of patients in our study that were prescribed acetylcholinesterase inhibitors and/or memantine had too many exclusion criteria to be accepted into dementia drug trials [10].

In five out of 25 countries, primary care physicians were entitled to officially prescribe reimbursable dementia drugs. In many other countries, primary care physicians could diagnose dementia unofficially and prescribe specific dementia drugs to patients that would not be reimbursed by their health insurance [9,10].

The participating countries were split into types according to the ability of primary care physicians to prescribe a dementia drug which could subsequently be reimbursed by the health insurance system: ‘permissive’ = primary care physicians always able to prescribe, ‘partially permissive’ = need for first prescription by secondary care specialist, and ‘non-permissive’ = mandatory secondary care prescribing and follow-up. Some primary care physicians from ‘non-permissive’ countries prescribed dementia drugs to their patients despite the restrictions for the purpose of mercy and equity as an unburdening action.

The MCQ analysis showed that the more primary care physicians were officially allowed to prescribe dementia drugs, the more they felt responsible for the diagnostic work-up. But they also then increasingly seemed to engage multiprofessional community health and home help services in unburdening tasks, thus providing psychosocial support.

Demographics, dementia prevalence, grades of dementia drug prescribing permissiveness in the participating countries and share of dementia drugs prescribed in the case stories per region are shown in Table 2.

Statistical analytical procedures also showed the relevance of Unburdening. Thus, statistical data were used in memos to test the basic social process core variable. This means that the statistics supported theory generation by making it less dependent on qualitative data only, due to the large amount of data readily coded quantitatively. After basic descriptive statistics, we employed the analytic procedures below during the selective coding phase.

(a) Cluster analyses

A two-step cluster analysis divided 151 case stories into two groups (four cases had missing data). Group 1 had 76 stories and group 2 had 75 stories. ‘Permissiveness to prescribe dementia drugs’ and ‘country’ predicted group affiliation (Figure 1).

Figure 1. Importance of predictors of primary care physician involvement in dementia work-up and treatment. Degree of involvement is dichotomised into two groups by a two-step cluster analysis. Cluster analysis is an exploratory method to identify structures within the data such as homogenous groups of cases if grouping is not previously known. ‘Exploratory’ means that it makes no distinction between dependent and independent variables. We used the SPSS Version 22 two-step cluster analysis. The most important predicting variables to allocate the informants in the two groups were ‘permissiveness to prescribe dementia drugs’ (Predictor importance PI = 1) and ‘country’ (PI = 0.61). All the other variables had a PI of < 0.02. Permissiveness: official permissiveness to prescribe typical dementia drug reimbursed by the local health care system. Country: country of the case and his/her primary care physician. Appropriate treatment: appropriate treatment according to the dementia guidelines and the label indication. Age: age of the case in years. Gender: gender of the case. MMSE: mini mental state examination. Number of words in case: word count in the case description.

Group 1 had high involvement of primary care physicians in the dementia work up and treatment. Patients were from Belgium, Denmark, Finland, France, Germany, Ireland, the Netherlands, Norway, Sweden, and Switzerland.

Group 2 had low involvement of primary care physicians in the dementia work up and treatment. Patients were from Austria, Bulgaria, Croatia, Greece, Hungary, Israel, Italy, Malta, Poland, Romania, Slovenia, Spain, and Turkey.

The different types of dementia (neurocognitive disorders) as assessed by a tertiary care physician (author SP) are shown in Table 3. Alzheimer’s disease was the most common dementia subtype followed by vascular dementia. In a third of the patients, no subtype could be specified due to lack of diagnostic information, which resulted in the unspecified diagnoses of mild or major neurocognitive disorders.

Legend: Memantine and acetylcholinesterase inhibitors were considered appropriately used if they were prescribed to patients with Alzheimer’s disease (AD), mixed dementia (if AD was considered one of the components), dementia with Lewy bodies or Parkinson’s disease dementia. The indication for the treatment was considered correct regardless of dementia stage (i.e. memantine was not restricted to moderate to severe AD and acetylcholinesterase inhibitors was not restricted to mild to moderate AD) [21].

(*) = appropriate prescription of acetylcholinesterase inhibitors/memantine.

(β) = questionable prescription of acetylcholinesterase inhibitors/memantine.

(†) = inappropriate prescription of acetylcholinesterase inhibitors/memantine.

(b) Cross-sectional associations by chi-square testing

There was a significant positive association between permissiveness to prescribe dementia drugs and primary care physicians’ diagnosis of dementia. MMSE testing was reported in 128 out of 155 cases (83%) and was significantly associated with permissiveness to prescribe dementia drugs but not with effective prescription of dementia drugs. We found no significant association between permissiveness to prescribe dementia drugs and the mentioning of dementia drugs or appropriateness of treatment. Neither did we find any significant association between appropriateness of treatment and early specialist involvement or referral. Statistical measures of the testing above are available online together with results of more advanced statistical methods applied to the data in a previous version of this study [10].

Discussion

Unburdening dementia emerged as an explanation of what physicians from 25 countries did to help patients with dementia and their caregivers after analysing both qualitative and quantitative data. Unburdening dementia is, according to grounded theory taxonomy, a core variable and was coded as a basic social process [14–16] starting with Recognising the burden by Burden Identification and Assessment followed by Burden Relief. As a core variable, Unburdening is suggested as a cohesive explanation for the resolution of a main concern – the comprehensive burden of dementia – and as such a tentative explanatory theory of dementia management in primary care.

We analysed case histories and survey responses from primary care physicians in 25 countries and found that only in 14% of 155 case stories was there no mention of any drug to relieve dementia problems. In more than half of the case stories, acetylcholinesterase inhibitors and/or memantine were mentioned as being prescribed and in one quarter of case stories, guideline indications of dementia drug treatment were broadened [17,18]. The physicians also used other drugs to unburden dementia such as antidepressants.

Free text data and MCQ responses, confirmed by a two-step cluster analysis, showed that the more the primary care physicians were officially allowed to prescribe dementia drugs the more they were responsible for the dementia work-up [9,10] also engaging community health and home help services in unburdening tasks. Pro-active dementia management by primary care physicians was related to geographical region with Central and Northern European physicians showing high permissiveness to prescribe dementia drugs in comparison with a low prescribing permissiveness in Eastern European and Mediterranean countries. This finding of regional differences within Europe confirmed a pattern seen previously [9,10].

‘Label indications’ of drugs are often limited and narrow [6,18]. Yet, both primary and secondary care physicians do not always apply a strict indication perspective. They have a patient with multiple severe conditions in front of them and try to do their best to help that patient [22]. The most common tool that many physicians use to help their patients is the prescription of drugs. Physicians inevitably tend to broaden the indications for drugs which could be beneficial even though the patient does not fulfill the eligibility criteria for prescription [23]. We call this pattern of physician behaviour Unburdening by drugs.

A majority of patients in our study that were prescribed specific dementia drugs would not have been accepted in dementia drug trials that sit as the base for the alleged evidence of their effects [10]. Patients in our study were indeed on average 80 years old and had significant co-morbidity. This suggests a discrepancy between real world primary care dementia patients and patients from acetylcholinesterase inhibitor trials where the efficacy of these drugs was determined. Patients in our study were thus old, with high co-morbidity and a late diagnosis often due to the difficulty of establishing a diagnosis. The discrepancy further applies to patients being included in disease modifying anti-amyloid trials aimed at relieving the dementia burden at the micro level [24,25]. Our study suggests that since many patients with dementia in primary care are treated outside of the traditional protocols for the drug trials that were designed to prove their effects, it would seem logical to expand the drug trial populations to include typical primary care patients.

Limitations

Day care rehabilitation, respite care and caregiver support [26] etc. are much less mentioned as Burden Relief procedures in our study as compared to prescribing dementia drugs of sometimes marginal therapeutic effect [17,18]. Why Unburdening by drugs emerged as the most common Burden Relief strategy used by the primary care physicians could perhaps be explained by a ‘prescription reflex’ response against therapeutic nihilism [27]. The big picture of the case stories analysed for this study resembles data from a systematic review of barriers to dementia management which showed limited access to and knowledge about community services and absence of interdisciplinary teams as well as attitudes of therapeutic nihilism [8]. The respondents in our study could have been biased for the eighth case story survey item by questions 3 and 4 in the MCQ survey that asked about drug treatment.

Our recruitment and sampling of key respondents was strategic, which limits generalizability. Also, the proportion of case story data from Ireland and Poland was higher than from other countries and differences within countries are not considered since the survey was anonymous. Yet, we used the same data collection approach for all countries. Moreover, with hundreds of pages of case story text and free text responses from several hundred primary care physicians we reached conceptual saturation according to grounded theory principles of fit, relevance, workability and modifiability [14,16]. These are qualities that in traditional qualitative data analysis often are labeled trustworthiness and generalizability. Hence, we suggest that Unburdening as a basic social process is enough abstract of time, place and people to be considered useful for a general understanding of practice habits of primary care physicians.

Our inductive method was based on classic grounded theory that mostly analyses qualitative data. Yet, we used quantitative measures too, rare for classic grounded theory but they fit our data [11–13]. Thus, Unburdening dementia emerged as a relevant basic social process. Since our data was based on what informants chose to report the results should, as in all classic grounded theory research, not be seen as facts but as tentative hypotheses. This is a limitation in deductive research but fits the tenets of the inductive property of the classic grounded theory method.

In many case stories, specification of the type of dementia was not given by the respondents and this is similar to other studies in primary care where the subtype of dementia was not considered [28]. Hence, a tertiary care physician researcher carefully examined all case stories and tried to establish the specific dementia type in accordance with DSM-5 [19].

Contribution to policy and practice

High permissiveness to prescribe dementia drugs was related to extensive dementia management by primary care physicians when compared with low permissiveness. This could be of interest for dementia care stakeholders as a way to incentivize dementia management [29]. Since studies exploring contemporary dementia management across different countries from a primary care perspective are rare Unburdening dementia could be a key for developing policies of dementia management not limited only to health care professionals.

To our knowledge, Unburdening presented as a basic social process [15] has not been published before for any health issue, let alone for dementia. Recognising dementia – the first stage of Unburdening – has indeed been much explored [29] and the burden concept often appears in qualitative research on chronic disease management in general and in dementia care in particular [7,8]. Hence, there is a vast literature about caregiver burden in dementia care resulting in emotional distress and burn-out [7]. In a grounded theory dissertation, unburdening was a subcore concept explaining caregivers coping by ‘telling their stories’ to the researcher [30].

Unburdening by drugs was accompanied by a broadening of guideline indications for dementia drugs. This was in some cases mentioned by physicians as motivated by mercy and equity. In a systematic review of psychosocial factors of patients’ and carers’ experiences of dementia diagnosis and treatment, it was found that dementia drugs gave hope and were considered as ‘worth a try’ although the benefits were not clear [31]. This view of expectations should not be neglected in dementia management to counter therapeutic nihilism [8,29]. Alas, ‘prescription reflex’ doctoring is especially risky for geriatric patients [27]. In this study, physicians thus seemed to rely more on drug treatment to relieve dementia burdens than what is proposed by today’s updated prescription guidelines where deprescribing is actually emphasised in unspecified dementia (but not in Alzheimer’s disease) [17].

It is almost needless to say that Unburdening by drugs has general implications for physicians concerning how they deal with many different health issues. We thus propose that Unburdening by drugs is what most practicing physicians do every day with or without evidence-based support for the drugs they are prescribing. So why should it be different for patients with dementia?

The conceptual framework of Unburdening could be further developed in order to understand practice habits for different diseases and hypotheses based on Unburdening may be tested deductively.

Conclusions

In this grounded theory analysis of an international primary care physician survey, a basic social process that we call Unburdening dementia emerged as a resolution for a core concern of the physicians. Unburdening is suggested as a tentative explanatory theory of dementia management in primary care starting with Recognising a dementia burden by Identification and Assessment of dementia followed by dementia Burden Relief.

Physicians typically identify the burden of both the patient and family members and then assess the cognitive impairment with MMSE in order to relieve the dementia burden, commonly by drug prescriptions, but also by community health and home help services in unburdening tasks. Dementia drug therapy seemed inappropriate in 40% of patients where primary care physicians broadened the guidelines with the purpose of Unburdening by drugs. Our findings have implications with regard to how dementia is managed in real world primary care across many jurisdictions.

Ethics approval and consent to participate

The participation of the physicians was voluntary. Except for in Ireland, the country that supplied the highest number of cases and where research ethics approval was obtained (ICGP-Bradley 2014/10/01), no formal research ethics approval was needed and therefore requested for the survey study in the remaining countries.

Some stable and well-controlled concomitant medical disorders were not reason for exclusion (hypertension, heart failure, diabetes and hypothyroidism). The list of reasons for exclusion was quite extensive and consistent across studies, other neurodegenerative illness, cardiovascular disease, or active cerebrovascular disease, clinically significant infarct dementia, psychiatric, hepatic, renal, pulmonary, metabolic, endocrine, active peptic ulcer, history of epilepsy, drug or alcohol abuse.

Rivastigmine

The list of exclusions was not extensive. Patients with severe and unstable illnesses (cardiovascular or pulmonary disease, unstable diabetes mellitus, peptic ulceration within the preceding five years, evidence of alcohol or substance abuse) were excluded, as were subjects taking medications such as anticholinergic drugs, acetyl-choline precursor health food supplements, memory enhancers, insulin and psychotropic drugs.
