Intervention components in the self-management of Parkinson’s: A mixed-methods synthesis of qualitative and quantitative evidence
INTRODUCTION:
Self-management interventions consist of multiple components to support people in the management of medical, emotional, and behavioural aspects of their condition, and aim to improve quality of life, function, and other outcomes. A systematic review of self-management interventions in Parkinson’s showed no conclusive evidence for effectiveness of specific self-management approaches in Parkinson’s to date but identified several potentially useful components.
AIM:
To identify the key required components for self-management in people with Parkinson’s by synthesising evidence from a body of primary qualitative evidence and systematic reviews, and to explore which of these key components should be incorporated into trials of self-management in Parkinson’s.
METHOD:
A mixed-methods synthesis was conducted. We combined data from two primary qualitative studies and a systematic review of qualitative studies that focused on self-management in Parkinson’s to identify key intervention components. These were then mapped onto the results of a systematic review of Randomised Controlled Trials (RCTs) using matrices. First, data were extracted from the qualitative studies with people with Parkinson’s and healthcare professionals on the key self-management components in this population. Second, a matrix table was created to map the identified Parkinson’s specific self-management components against potential effectiveness from published RCTs of self-management interventions.
RESULTS:
Synthesis of qualitative data identified 15 potential self-management components. These 15 components included components needed to start self-managing (e.g., information, skill acquirement) and components needed to maintain self-managing (e.g., self-motoring, increasing motivation). From 18 RCTs, interventions varied in how many components were included (range 1–10). Trials reporting significant beneficial effects of their intervention included a higher number of components (4 or more self-management components) than trials without significant findings (1–3 self-management components).
CONCLUSION:
Fifteen key self-management components were identified that should be incorporated into interventions or programs of self-management in Parkinson’s. No current trial has incorporated all aspects, but a higher number of these key components appears to make trials of self-management interventions more likely to be successful
The Compound Impact of Cognitive and Physical Decline: A Qualitative Interview Study of People with Parkinson’s and Cognitive Impairment, Caregivers and Professionals
Remote Consultations for People with Parkinson’s and Cognitive Impairment – A Qualitative Study with Patients, Caregivers and Healthcare Professionals
Background:
The Covid-19 pandemic led to many consultations being conducted remotely. Cognitive impairment is recognised as a potential barrier to remote healthcare interactions and is common and heterogeneous in Parkinson’s. Research studies have shown remote consultations in Parkinson’s to be feasible, but little is known about real life experience, especially for those with cognitive impairment. We explored the experiences and perceptions of remote consultations for people with Parkinson’s and cognitive impairment.
Objective:
To explore the experiences of remote consultations for People with Parkinson’s and Cognitive Impairments, from the perspective of service users and professionals, and investigate considerations for future service delivery.
Method:
Semi-structured interviews were conducted remotely with 11 people with Parkinson’s and cognitive impairment, 10 family caregivers and 24 Healthcare Professionals in 2020-2021. Purposive sampling was used. Interviews were audio-recorded, transcribed and analysed using thematic analysis.
Results:
Four themes were identified: The Nature of Remote Interactions; Challenges Exacerbated by Being Remote; Expectation versus Reality; and Optimising for the Future. Remote consultations were considered to be ‘transactional’ and less personal, with difficulties building rapport, and different in role to in-person consultations. The loss of non-verbal communication and ability of Healthcare Professionals to ‘sense’ led to remote consultations being perceived as riskier by all groups. Issues arising from communication and cognitive impairment, balancing of the person with Parkinson’s and caregiver voice, and discussions of the future, affect this population specifically. Remote consultations were reported to have been more successful than anticipated in all three groups. Obstacles were not always as expected, for example age was less of a barrier than predicted. Video consultations were perceived as being preferable to telephone consultations by most participants, but not accessible to all people with Parkinson’s. With widespread expectation of ongoing remote consultations, potential improvements for these three groups and healthcare services were identified, including practice, preparation, increased awareness of issues, expectation management by Healthcare Professionals, and more time and flexibility for consultations.
Conclusion:
Advantages and challenges of remote consultations for this population are identified. Consultations could be improved with increased support, practice, preparation, awareness of issues, and more time and flexibility within services
Delivering Optimal Care to People with Cognitive Impairment in Parkinson’s Disease: A Qualitative Study of Patient, Caregiver, and Professional Perspectives
Background:
Cognitive impairment is common in Parkinson’s disease (PD) and associated with lower quality of life. Cognitive impairment in PD manifests differently to other dementia pathologies. Provision of optimal care requires knowledge about the support needs of this population.
//
Methods: Eleven people with PD and cognitive impairment (PwP), 10 family caregivers, and 27 healthcare professionals were purposively sampled from across the United Kingdom. Semistructured interviews were conducted in 2019–2021, audio-recorded, transcribed, and analysed using reflexive thematic analysis.
//
Results: Cognitive impairment in PD conveyed increased complexity for clinical management and healthcare interactions, the latter driven by multifactorial communication difficulties. Techniques that helped included slow, simple, and single messages, avoiding topic switching. Information and emotional support needs were often unmet, particularly for caregivers. Diagnostic pathways were inconsistent and awareness of cognitive impairment in PD was poor, both contributing to underdiagnosis. Many felt that PwP and cognitive impairment fell through service gaps, resulting from disjointed, nonspecific, and underresourced services. Personalised care was advocated through tailoring to individual needs of PwP and caregivers facilitated by flexibility, time and continuity within services, and supporting self-management.
//
Conclusions: This study highlights unmet need for people with this complex condition. Clinicians should adapt their approach and communication techniques for this population and provide tailored information and support to both PwP and caregivers. Services need to be more streamlined and collaborative, providing more time and flexibility. There is a need for wider awareness and deeper understanding of this condition and its differences from other types of dementia
Exploring the experiences of people and family carers from under-represented groups in self-managing Parkinson’s disease and their use of digital health to do this
Introduction:
Digital health is thought to enable people to better manage chronic conditions, such as Parkinson's. However, little is known about how people from under-represented groups with chronic conditions use digital health to self-manage.
Objective:
The objective of our study was to explore the experiences of people and family carers from under-represented groups in self-managing Parkinson's, including their use of digital health to do this.
Methods:
Semi-structured interviews (n = 18, including four dyadic) were conducted remotely, with 16 people with Parkinson's and six family carers in 2020–2021. Participants were purposively sampled from under-represented groups: belong to an ethnic minority, or having significant physical or sensory impairment. Interviews were audio-recorded, transcribed and analysed using thematic analysis.
Results:
Three main themes of importance were developed: ‘self-management support’, ‘digital health use to support self-management’ and ‘identity, attitudes and characteristics’. Participants received medical, psychological, social and practical self-management support. Some participants used digital health resources, e.g., Parkinson's UK website. Digital literacy was the biggest barrier to using digital health, regardless of background, often dependant on previous occupation and confidence. Few ethnic minority participants thought race or culture alters self-management ability and most believed there was no need for digital health interventions to be tailored to an individual's race or culture. Some felt inclusivity was important in terms of diverse images of people. A range of considerations were identified to optimise digital health, such as assistive equipment for people with sensory impairment.
Conclusions:
Barriers to using digital health for self-management were primarily dependent on personal factors including digital literacy and attitudes but rarely race or culture. We recommend the optimisation of digital health interventions by providing assistive technology at low cost, and visual inclusiveness should be promoted by including images of people from diverse backgrounds
Illusions and Delusions: Relating Experimentally-Induced False Memories to Anomalous Experiences and Ideas
The salience hypothesis of psychosis rests on a simple but profound observation that subtle alterations in the way that we perceive and experience stimuli have important consequences for how important these stimuli become for us, how much they draw our attention, how they embed themselves in our memory and, ultimately, how they shape our beliefs. We put forward the idea that a classical memory illusion – the Deese–Roediger–McDermott (DRM) effect – offers a useful way of exploring processes related to such aberrant belief formation. The illusion occurs when, as a consequence of its relationship to previous stimuli, a stimulus that has not previously been presented is falsely remembered. Such illusory familiarity is thought to be generated by the surprising fluency with which the stimulus is processed. In this respect, the illusion relates directly to the salience hypothesis and may share common cognitive underpinnings with aberrations of perception and attribution that are found in psychosis. In this paper, we explore the theoretical importance of this experimentally-induced illusion in relation to the salience model of psychosis. We present data showing that, in healthy volunteers, the illusion relates directly to self reported anomalies of experience and magical thinking. We discuss this finding in terms of the salience hypothesis and of a broader Bayesian framework of perception and cognition which emphasizes the salience both of predictable and unpredictable experiences
The role of diffusion-driven pure climb creep on the rheology of bridgmanite under lower mantle conditions
The viscosity of Earth’s lower mantle is poorly constrained due to the lack of knowledge on some fundamental variables that affect the deformation behaviour of its main mineral phases. This study focuses on bridgmanite, the main lower mantle constituent, and assesses its rheology by developing an approach based on mineral physics. Following and revising the recent advances in this field, pure climb creep controlled by diffusion is identified as the key mechanism driving deformation in bridgmanite. The strain rates of this phase under lower mantle pressures, temperatures and stresses are thus calculated by constraining diffusion and implementing a creep theoretical model. The viscosity of MgSiO_3 bridgmanite resulting from pure climb creep is consequently evaluated and compared with the viscosity profiles available from the literature. We show that the inferred variability of viscosity in these profiles can be fully accounted for with the chosen variables of our calculation, e.g., diffusion coefficients, vacancy concentrations and applied stresses. A refinement of these variables is advocated in order to further constrain viscosity and match the observables
Measuring the availability of human resources for health and its relationship to universal health coverage for 204 countries and territories from 1990 to 2019: a systematic analysis for the Global Burden of Disease Study 2019
Background: Human resources for health (HRH) include a range of occupations that aim to promote or improve human health. The UN Sustainable Development Goals (SDGs) and the WHO Health Workforce 2030 strategy have drawn attention to the importance of HRH for achieving policy priorities such as universal health coverage (UHC). Although previous research has found substantial global disparities in HRH, the absence of comparable cross-national estimates of existing workforces has hindered efforts to quantify workforce requirements to meet health system goals. We aimed to use comparable and standardised data sources to estimate HRH densities globally, and to examine the relationship between a subset of HRH cadres and UHC effective coverage performance.
Methods: Through the International Labour Organization and Global Health Data Exchange databases, we identified 1404 country-years of data from labour force surveys and 69 country-years of census data, with detailed microdata on health-related employment. From the WHO National Health Workforce Accounts, we identified 2950 country-years of data. We mapped data from all occupational coding systems to the International Standard Classification of Occupations 1988 (ISCO-88), allowing for standardised estimation of densities for 16 categories of health workers across the full time series. Using data from 1990 to 2019 for 196 of 204 countries and territories, covering seven Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) super-regions and 21 regions, we applied spatiotemporal Gaussian process regression (ST-GPR) to model HRH densities from 1990 to 2019 for all countries and territories. We used stochastic frontier meta-regression to model the relationship between the UHC effective coverage index and densities for the four categories of health workers enumerated in SDG indicator 3.c.1 pertaining to HRH: physicians, nurses and midwives, dentistry personnel, and pharmaceutical personnel. We identified minimum workforce density thresholds required to meet a specified target of 80 out of 100 on the UHC effective coverage index, and quantified national shortages with respect to those minimum thresholds.
Findings: We estimated that, in 2019, the world had 104·0 million (95% uncertainty interval 83·5–128·0) health workers, including 12·8 million (9·7–16·6) physicians, 29·8 million (23·3–37·7) nurses and midwives, 4·6 million (3·6–6·0) dentistry personnel, and 5·2 million (4·0–6·7) pharmaceutical personnel. We calculated a global physician density of 16·7 (12·6–21·6) per 10 000 population, and a nurse and midwife density of 38·6 (30·1–48·8) per 10 000 population. We found the GBD super-regions of sub-Saharan Africa, south Asia, and north Africa and the Middle East had the lowest HRH densities. To reach 80 out of 100 on the UHC effective coverage index, we estimated that, per 10 000 population, at least 20·7 physicians, 70·6 nurses and midwives, 8·2 dentistry personnel, and 9·4 pharmaceutical personnel would be needed. In total, the 2019 national health workforces fell short of these minimum thresholds by 6·4 million physicians, 30·6 million nurses and midwives, 3·3 million dentistry personnel, and 2·9 million pharmaceutical personnel.
Interpretation: Considerable expansion of the world's health workforce is needed to achieve high levels of UHC effective coverage. The largest shortages are in low-income settings, highlighting the need for increased financing and coordination to train, employ, and retain human resources in the health sector. Actual HRH shortages might be larger than estimated because minimum thresholds for each cadre of health workers are benchmarked on health systems that most efficiently translate human resources into UHC attainment
Variation in Childhood Diarrheal Morbidity and Mortality in Africa, 2000-2015.
BACKGROUND: Diarrheal diseases are the third leading cause of disease and death in children younger than 5 years of age in Africa and were responsible for an estimated 30 million cases of severe diarrhea (95% credible interval, 27 million to 33 million) and 330,000 deaths (95% credible interval, 270,000 to 380,000) in 2015. The development of targeted approaches to address this burden has been hampered by a paucity of comprehensive, fine-scale estimates of diarrhea-related disease and death among and within countries. METHODS: We produced annual estimates of the prevalence and incidence of diarrhea and diarrhea-related mortality with high geographic detail (5 km2) across Africa from 2000 through 2015. Estimates were created with the use of Bayesian geostatistical techniques and were calibrated to the results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2016. RESULTS: The results revealed geographic inequality with regard to diarrhea risk in Africa. Of the estimated 330,000 childhood deaths that were attributable to diarrhea in 2015, more than 50% occurred in 55 of the 782 first-level administrative subdivisions (e.g., states). In 2015, mortality rates among first-level administrative subdivisions in Nigeria differed by up to a factor of 6. The case fatality rates were highly varied at the national level across Africa, with the highest values observed in Benin, Lesotho, Mali, Nigeria, and Sierra Leone. CONCLUSIONS: Our findings showed concentrated areas of diarrheal disease and diarrhea-related death in countries that had a consistently high burden as well as in countries that had considerable national-level reductions in diarrhea burden.
