Development and validation of a novel patient-reported outcome measure in people with episodic migraine and chronic migraine: The Activity Impairment in Migraine Diary

Objective

To evaluate the content validity and psychometric properties of the Activity Impairment in Migraine Diary (AIM‐D).

Background

Measuring treatment effects on migraine impairment requires a psychometrically sound patient‐reported outcome (PRO) measure developed consistent with U.S. Food and Drug Administration guidance.

Methods

The AIM‐D was created from concepts that emerged during qualitative interviews with five clinicians experienced in treating migraine and concept elicitation (CE) interviews with 40 adults with episodic migraine (EM) or chronic migraine (CM). The initial version was refined based on three waves of cognitive interviews with 38 adults with EM or CM and input from a panel of clinical and measurement experts. The AIM‐D was psychometrically evaluated using data from 316 adults with EM or CM who participated in a 13‐week prospective observational study. Study participants completed PRO assessments including the AIM‐D and a daily headache diary. Exploratory and confirmatory factor analysis were used to determine the factor structure. The reliability, validity, and responsiveness of the AIM‐D were assessed. Additional PRO measures including the Patient Global Impression – Severity (PGI‐S), Migraine Specific Quality of Life Questionnaire, Version 2.1 Role Function‐Restrictive domain, and Headache Impact Test were used for psychometric evaluation of the AIM‐D.

Results

Based on CE interviews with adults with migraine and input from an expert panel, activity impairment was identified as the target in the preliminary conceptual framework, which had two domains: performance of daily activities (PDAs) and physical impairment (PI). Revision of the draft AIM‐D through multiple rounds of cognitive interviews and expert panel meetings resulted in a content valid 11‐item version. Exploratory factor analysis supported both one‐ and two‐domain structures for the AIM‐D, which were further supported by confirmatory factor analysis (factor loadings all >0.90). The AIM‐D domains (PDA and PI) and total score showed high internal consistency reliability (Cronbach's alpha 0.95–0.97), acceptable test–retest reliability for weekly average scores (intraclass correlation coefficient >0.60 for participants with no change in PGI‐S between baseline and week 2), and good convergent and known‐groups validity. There was evidence of responsiveness based on changes in PGI‐S score and monthly migraine days.

Conclusion

The AIM‐D is a content valid and psychometrically sound measure designed to evaluate activity impairment and is suitable for use in clinical trials of preventive treatments for EM or CM.

Learning from mistakes when reporting urgent and emergency vascular studies

The majority of out-of-hours cases relate to neurological, chest, and gastrointestinal pathologies with acute vascular cases being encountered less commonly. Trainees and exposure of non-vascular/interventional radiology (IR) consultants to angiographic imaging is often limited in working hours and this may lead to reporting on-call cases outside of normal daytime practice. In a recent local review, a number on-call vascular studies were found to contain a number of vascular-related discrepancies. Vascular reporting is a complex subspecialty, which comprises many clear diagnoses (large vessel occlusions, large vessel aneurysms, or dissections); however, also several subtle and complex abnormalities. These more subtle abnormalities, at times, require dedicated vascular specialist review to ensure subtle findings are communicated appropriately to the clinical team. The recent increased complexity of endovascular treatments and their complications has also provided further challenge for the non-specialist reporter. Similarly, improved imaging techniques have allowed for non-obvious but significant findings that may require urgent management, such as small aneurysms and dissection flaps. We will review a range of key vascular findings that demonstrate learning opportunities, particularly within the acute and on-call settings. These will include gastrointestinal haemorrhage, subtle aortic pathologies, head and neck vascular emergencies, small to mid-sized vessel injuries and imaging of post-procedural complications. Educational hints and tips will be provided to enable learning from mistakes encountered by trainees and non-vascular specialist radiologists in the on-call or urgent reporting settings, and these will be reviewed with reference to the literature.

Development of the Near Vision Presbyopia Task-based Questionnaire for use in evaluating the impact of presbyopia

Background

Presbyopia is a progressive condition that reduces the eye’s ability to focus on near objects with increasing age. After a systematic literature review identified no existing presbyopia-specific patient-reported outcome (PRO) instruments meeting regulatory guidance, a new PRO instrument, the Near Vision Presbyopia Task-based Questionnaire (NVPTQ), was developed.

Results

To explore the patient experience with presbyopia, concept elicitation interviews were conducted with 20 presbyopic participants. The most frequently reported impacts were difficulty with reading menus/books/newspapers/magazines, reading on a cell phone/caller ID, and reading small print. Based on these results, a task-based PRO instrument (the NVPTQ) was developed instructing participants to complete four near-vision, paper-based reading tasks (book, newspaper, nutrition label, menu) under standardized settings, and subsequently assess their vision-related reading ability and associated satisfaction. The draft NVPTQ was cognitively debriefed with a sample of 20 presbyopes, which demonstrated that most participants interpreted the items as intended and endorsed the relevance of the concepts being assessed. After the qualitative research, the draft instrument was psychometrically tested using data from a Phase 2 study. Based on item-level analyses, all items in the NVPTQ demonstrated expected response option patterns and lacked substantial floor or ceiling effects. The reliability, validity, and responsiveness of the NVPTQ Performance and Satisfaction domain scores were assessed. All domains scores had large Cronbach’s coefficient α values and good test–retest statistics, indicating that the scores are internally consistent and produce stable values over time. The pattern of correlations with a concurrent measure of visual functioning (National Eye Institute Visual Function Questionnaire 25) demonstrated that the NVPTQ domain scores were related to an alternative assessment of near-vision activities. The NVPTQ domain scores were able to distinguish between groups that were known to differ on the clinical outcome of uncorrected near visual acuity, supporting the construct validity of these scores. The NVPTQ domain scores showed evidence of responsiveness to change by being able to distinguish between groups defined as improved and not improved based on patient-reported and clinical outcomes.

Conclusions

This research has resulted in a content-valid and psychometrically sound instrument designed to evaluate vision-related reading ability and satisfaction with vision-related reading ability.

The development and validation of population clusters for integrating health and social care: A protocol for a mixed-methods study in Multiple Long-Term Conditions (Cluster-AIM) (Preprint)

Background

Multiple long-term health conditions (multimorbidity) (MLTC-M) are increasingly prevalent and associated with high rates of morbidity, mortality, and health care expenditure. Strategies to address this have primarily focused on the biological aspects of disease, but MLTC-M also result from and are associated with additional psychosocial, economic, and environmental barriers. A shift toward more personalized, holistic, and integrated care could be effective. This could be made more efficient by identifying groups of populations based on their health and social needs. In turn, these will contribute to evidence-based solutions supporting delivery of interventions tailored to address the needs pertinent to each cluster. Evidence is needed on how to generate clusters based on health and social needs and quantify the impact of clusters on long-term health and costs.

Objective

We intend to develop and validate population clusters that consider determinants of health and social care needs for people with MLTC-M using data-driven machine learning (ML) methods compared to expert-driven approaches within primary care national databases, followed by evaluation of cluster trajectories and their association with health outcomes and costs.

Methods

The mixed methods program of work with parallel work streams include the following: (1) qualitative semistructured interview studies exploring patient, caregiver, and professional views on clinical and socioeconomic factors influencing experiences of living with or seeking care in MLTC-M; (2) modified Delphi with relevant stakeholders to generate variables on health and social (wider) determinants and to examine the feasibility of including these variables within existing primary care databases; and (3) cohort study with expert-driven segmentation, alongside data-driven algorithms. Outputs will be compared, clusters characterized, and trajectories over time examined to quantify associations with mortality, additional long-term conditions, worsening frailty, disease severity, and 10-year health and social care costs.

Results

The study will commence in October 2021 and is expected to be completed by October 2023.

Conclusions

By studying MLTC-M clusters, we will assess how more personalized care can be developed, how accurate costs can be provided, and how to better understand the personal and medical profiles and environment of individuals within each cluster. Integrated care that considers “whole persons” and their environment is essential in addressing the complex, diverse, and individual needs of people living with MLTC-M.

Development of the Presbyopia Impact and Coping Questionnaire

INTRODUCTION

Presbyopia is a progressive, age-related visual condition that is characterized by reduced ability to focus on near/close objects, causing impacts on individuals' daily function and health-related quality of life. The Presbyopia Impact and Coping Questionnaire (PICQ) is a new patient-reported outcome (PRO) instrument that assesses presbyopia impact and use of coping behaviors among presbyopic individuals.

METHODS

To document the impacts of presbyopia and associated coping behaviors, concept elicitation (CE) interviews were conducted with 20 presbyopic participants. Results from the CE interviews were used to develop draft items for additional testing. Following item generation, the draft PICQ was cognitively debriefed with 20 participants. Data from a phase 2 controlled clinical trial were used for psychometric analyses of the PICQ. The PICQ was administered at site visits throughout a 28-day treatment period. Confirmatory factor analysis (CFA) methods were used to guide the development of the scoring algorithm. The reliability (internal consistency, test-retest), construct validity (convergent and discriminant validity, known-groups methods), and responsiveness (Guyatt's responsiveness statistic [GRS]) of the PICQ scores were evaluated. Finally, anchor-based and distribution-based methods were used to inform thresholds for interpreting meaningful within-patient change.

RESULTS

CE interviews identified the important and relevant presbyopia-related impacts and coping behaviors and 22 items were drafted and cognitively debriefed. Following minor revisions and item addition/deletion, a version of the PICQ including 23 items was subjected to psychometric testing. The analysis sample included 151 participants. The CFA established two PICQ domain scores, Coping and Impact, on 0-to-4 scales that demonstrate good model fit (root mean square error of approximation = 0.06, comparative fit index = 0.98, Tucker-Lewis index = 0.98, standardized root mean square = 0.07). Cronbach's alphas for the Coping and Impact scores were 0.89 and 0.84, respectively. Test-retest intraclass correlation coefficients were 0.77 for Coping and 0.67 for Impact. The pattern of results assessing construct validity was acceptable for the PICQ Coping and Impact scores, with the magnitude of correlations and effect sizes generally meeting a priori expectations. The corresponding GRS effect sizes for the PICQ Coping scores were -1.23 (i.e., large) for Patient Global Impression of Change (PGIC) and -0.72 (i.e., medium) for uncorrected near visual acuity (UNVA). The GRS effect sizes for the PICQ Impact scores were -0.60 (i.e., medium) for PGIC and -0.35 (i.e., small) for UNVA. Across three sets of anchor-based analyses for interpreting individual-level change, a responder threshold of -1.00 was identified for both PICQ Coping and PICQ Impact scores.

CONCLUSIONS

The totality of evidence from the qualitative and quantitative research establishes that the PICQ scores produced are valid and reliable measures of presbyopia impacts and coping behaviors that are important and relevant for assessing presbyopia treatment outcomes. CLINICALTRIALS.

Racial and socioeconomic disparities in multimorbidity and associated healthcare utilisation and outcomes in Brazil: a cross-sectional analysis of three million individuals

BACKGROUND

Evidence is limited on racial/ethnic group disparities in multimorbidity and associated health outcomes in low- and middle-income countries hampering effective policies and clinical interventions to address health inequalities.

METHODS

This study assessed race/ethnic and socioeconomic disparities in the prevalence of multimorbidity and associated healthcare utilisation, costs and death in Rio de Janeiro, Brazil. A cross-sectional analysis was carried out of 3,027,335 individuals registered with primary healthcare (PHC) services. Records included linked data to hospitalisation, mortality, and welfare-claimant (Bolsa Família) records between 1 Jan 2012 and 31 Dec 2016. Logistic and Poisson regression models were carried out to assess the likelihood of multimorbidity (two or more diagnoses out of 53 chronic conditions), PHC use, hospital admissions and mortality from any cause. Interactions were used to assess disparities.

RESULTS

In total 13,509,633 healthcare visits were analysed identifying 389,829 multimorbid individuals (13%). In adjusted regression models, multimorbidity was associated with lower education (Adjusted Odds Ratio (AOR): 1.26; 95%CI: 1.23,1.29; compared to higher education), Bolsa Família receipt (AOR: 1.14; 95%CI: 1.13,1.15; compared to non-recipients); and black race/ethnicity (AOR: 1.05; 95%CI: 1.03,1.06; compared to white). Multimorbidity was associated with more hospitalisations (Adjusted Rate Ratio (ARR): 2.75; 95%CI: 2.69,2.81), more PHC visits (ARR: 3.46; 95%CI: 3.44,3.47), and higher likelihood of death (AOR: 1.33; 95%CI: 1.29,1.36). These associations were greater for multimorbid individuals with lower educational attainment (five year probability of death 1.67% (95%CI: 1.61,1.74%) compared to 1.13% (95%CI: 1.02,1.23%) for higher education), individuals of black race/ethnicity (1.48% (95%CI: 1.41,1.55%) compared to 1.35% (95%CI: 1.31,1.40%) for white) and individuals in receipt of welfare (1.89% (95%CI: 1.77,2.00%) compared to 1.35% (95%CI: 1.31,1.38%) for non-recipients).

CONCLUSIONS

The prevalence of multimorbidity and associated hospital admissions and mortality are greater in individuals with black race/ethnicity and other deprived socioeconomic groups in Rio de Janeiro. Interventions to better prevent and manage multimorbidity and underlying disparities in low- and middle-income country settings are needed.

Development and content validity of the Barth Syndrome Symptom Assessment (BTHS-SA) for adolescents and adults

Background

Barth Syndrome (BTHS) is a rare genetic disorder that presents as a complex of debilitating symptoms and reduced life expectancy. Well-developed, BTHS-specific assessments measuring primary signs and symptoms of BTHS are not currently available, making it difficult to evaluate treatment effects in BTHS clinical studies. The objective of this research was to develop symptom-focused patient-reported outcome (PRO) measures for use in clinical studies with adolescents and adults with BTHS.

Methods

Concept elicitation interviews (CEIs) with pediatric (n = 18, age < 16 years) and adult (n = 15, age ≥ 16 years) individuals with BTHS and/or their caregivers were conducted to identify signs and symptoms relevant to BTHS and important to individuals with the condition. Based on CEI results, questionnaire construction activities were conducted to create unique adolescent and adult versions of the Barth Syndrome-Symptom Assessment (BTHS-SA). The questionnaires were evaluated in cognitive debriefing interviews (CDIs) with adolescents (n = 12; age 12- < 16 years) and adults (n = 12; age ≥ 16 years) with BTHS to assess relevance and readability of the tools.

Results

During the CEIs, a total of 48 and 40 signs and symptoms were reported by the pediatric and adult groups, respectively; 31 were reported by both age groups. Fatigue/tiredness and muscle weakness were the symptoms most frequently reported by both pediatric and adult patients with BTHS as important to improve with an effective treatment. The CEI results informed construction of a nine-item version of the BTHS-SA for adolescents and an eight-item version for adults. Developed for daily administration, each version asks respondents to rate symptom severity “at its worst” over the 24 h prior to administration. CDIs with both adolescents and adults with BTHS demonstrated that each BTHS-SA version was reflective of the disease experience and that respondents could interpret the questionnaire as intended and provide responses that accurately reflected their symptom experience.

Conclusions

The BTHS-SA adolescent and adult versions are content-valid PRO measures that can be used to evaluate severity of disease-specific symptoms in future clinical trials. Given the lack of available and well-developed assessments in this underserved therapeutic area, these tools fulfill a need for clinical researchers developing treatments for individuals with BTHS.

The effect of payment method and multimorbidity on health and healthcare utilisation

Purpose

Three types of payment methods have been introduced across European countries in attempts to encourage better, more integrated care of persons with multimorbidity: pay-for-performance; pay-for-coordination; and an all-inclusive payment method. We examine whether there are differences in the way these payment methods affect health and healthcare use in persons with multimorbidity.

Design/methodology/approach

Using individual-level survey data from twenty European countries, we examine unadjusted differences in average outcomes for the years 2011–2015 by whether countries adopted new payment methods for integrated care. We then test for a differential effect for multimorbid persons using linear, individual random effects regressions, including country and time fixed effects and clustering standard errors at the country level.

Findings

We find little effect of varying payment methods on key outcomes for multimorbid individuals despite the theoretical predictions and the rhetoric in many policy documents.

Research limitations/implications

Policymakers should bear in mind that the success of the payment method relies on the specific design of the incentives and their implementation. New effective models of care and how to incentivise these for multimorbid patients is an ongoing research priority.

Originality/value

This paper is the first to study the effects of payments for integration on the dimensions and populations these schemes intend to affect; health and healthcare use at the individual level for multimorbid individuals.

Bundled payments for chronic diseases increased health care expenditure in the Netherlands, especially for multimorbid patients

Bundled payments aim to stimulate the integration of healthcare services and ultimately reduce healthcare expenditure growth through improved quality of care. The Netherlands introduced bundled payments for chronic diseases in 2010 by reimbursing providers annually for a bundle of primary care services related to COPD, Diabetes, or Vascular Risk Management. We aimed to assess the long-term effects of these bundled payments on healthcare expenditure. We used health insurance claims data from 2008 to 2015 to compare the healthcare expenditure between everyone who was included in bundled payments and a control group. We performed a difference-in-difference analysis in combination with propensity score matching and found that bundled payments consistently increased health care expenditure over seven years. The average half-year increase was €233 (95%CI: 204-262) for DM2, €609 (95%CI: 533-686) for COPD, and €231 (95%CI: 208-254) for VRM, representing 13%, 52%, and 20% of 2008 half-year cost. The increase was higher for those with multimorbidity compared to those without multimorbidity. This suggests that the expectations of the bundled payments are yet to be fulfilled.

Does prevention-focused integration lead to the triple aim? An evaluation of two new care models in England

OBJECTIVES

To examine the effectiveness of two integrated care models ('vanguards') in Salford and South Somerset in England, United Kingdom, in relation to patient experience, health outcomes and costs of care (the 'triple aim').

METHODS

We used difference-in-differences analysis combined with propensity score weighting to compare the two care model sites with control ('usual care') areas in the rest of England. We estimated combined and separate annual effects in the three years following introduction of the new care model, using the national General Practice Patient Survey (GPPS) to measure patient experience (inter-organisational support with chronic condition management) and generic health status (EQ-5D); and hospital episode statistics (HES) data to measure total costs of secondary care. As secondary outcomes we measured proxies for improved prevention: cost per user of secondary care (severity); avoidable emergency admissions; and primary care utilisation.

RESULTS

Both intervention sites showed an increase in total costs of secondary care (approximately £74 per registered patient per year in Salford, £45 in South Somerset) and cost per user of secondary care (£130-138 per person per year). There were no statistically significant effects on health status or patient experience of care. There was a more apparent short-term negative effect on measured outcomes in South Somerset, in terms of increased costs and avoidable emergency admissions, but these reduced over time.

CONCLUSION

New care models such as those implemented within the Vanguard programme in England might lead to unintended secondary care cost increases in the short to medium term. Cost increases appeared to be driven by average patient severity increases in hospital. Prevention-focused population health management models of integrated care, like previous more targeted models, do not immediately improve the health system's triple aim.

Excess mortality for care home residents during the first 23 weeks of the COVID-19 pandemic in England: a national cohort study

BACKGROUND

To estimate excess mortality for care home residents during the COVID-19 pandemic in England, exploring associations with care home characteristics.

METHODS

Daily number of deaths in all residential and nursing homes in England notified to the Care Quality Commission (CQC) from 1 January 2017 to 7 August 2020. Care home-level data linked with CQC care home register to identify home characteristics: client type (over 65s/children and adults), ownership status (for-profit/not-for-profit; branded/independent) and size (small/medium/large). Excess deaths computed as the difference between observed and predicted deaths using local authority fixed-effect Poisson regressions on pre-pandemic data. Fixed-effect logistic regressions were used to model odds of experiencing COVID-19 suspected/confirmed deaths.

RESULTS

Up to 7 August 2020, there were 29,542 (95% CI 25,176 to 33,908) excess deaths in all care homes. Excess deaths represented 6.5% (95% CI 5.5 to 7.4%) of all care home beds, higher in nursing (8.4%) than residential (4.6%) homes. 64.7% (95% CI 56.4 to 76.0%) of the excess deaths were confirmed/suspected COVID-19. Almost all excess deaths were recorded in the quarter (27.4%) of homes with any COVID-19 fatalities. The odds of experiencing COVID-19 attributable deaths were higher in homes providing nursing services (OR 1.8, 95% CI 1.6 to 2.0), to older people and/or with dementia (OR 5.5, 95% CI 4.4 to 6.8), amongst larger (vs. small) homes (OR 13.3, 95% CI 11.5 to 15.4) and belonging to a large provider/brand (OR 1.2, 95% CI 1.1 to 1.3). There was no significant association with for-profit status of providers.

CONCLUSIONS

To limit excess mortality, policy should be targeted at care homes to minimise the risk of ingress of disease and limit subsequent transmission. Our findings provide specific characteristic targets for further research on mechanisms and policy priority.

Drivers of successful implementation of integrated care for multi-morbidity: Mechanisms identified in 17 case studies from 8 European countries

This paper provides a deeper understanding of the mechanisms underlying implementation strategies for integrated care. As part of the SELFIE project, 17 integrated care programmes addressing multi-morbidity from eight European countries were selected and studied. Data was extracted from 'thick descriptions' of the 17 programmes and analysed both inductively and deductively using implementation theory. The following ten mechanisms for successful implementation of integrated care were identified. With regards to service delivery, successful implementers (1) commonly adopted an incremental growth model rather than a disruptive innovation approach, and found (2) a balance between flexibility and formal structures of integration. For leadership & governance, they (3) applied collaborative governance by engaging all stakeholders, and (4) distributed leadership throughout all levels of the system. For the workforce, these implementers (5) were able to build a multidisciplinary team culture with mutual recognition of each other's roles, and (6) stimulated the development of new roles and competencies for integrated care. With respect to financing, (7) secured long-term funding and innovative payments were applied as means to overcome fragmented financing of health and social care. Implementers emphasised (8) the implementation of ICT that was specifically developed to support collaboration and communication rather than administrative procedures (technology & medical devices), and (9) created feedback loops and a continuous monitoring system (information & research). The overarching mechanism was that implementers (10) engaged in alignment work across the different components and levels of the health and social care system. These evidence-based mechanisms for implementation are applicable in different local, regional and national contexts.

Multimorbidity combinations, costs of hospital care and potentially preventable emergency admissions in England: A cohort study

BACKGROUND

Patients with multimorbidities have the greatest healthcare needs and generate the highest expenditure in the health system. There is an increasing focus on identifying specific disease combinations for addressing poor outcomes. Existing research has identified a small number of prevalent "clusters" in the general population, but the limited number examined might oversimplify the problem and these may not be the ones associated with important outcomes. Combinations with the highest (potentially preventable) secondary care costs may reveal priority targets for intervention or prevention. We aimed to examine the potential of defining multimorbidity clusters for impacting secondary care costs.

METHODS AND FINDINGS

We used national, Hospital Episode Statistics, data from all hospital admissions in England from 2017/2018 (cohort of over 8 million patients) and defined multimorbidity based on ICD-10 codes for 28 chronic conditions (we backfilled conditions from 2009/2010 to address potential undercoding). We identified the combinations of multimorbidity which contributed to the highest total current and previous 5-year costs of secondary care and costs of potentially preventable emergency hospital admissions in aggregate and per patient. We examined the distribution of costs across unique disease combinations to test the potential of the cluster approach for targeting interventions at high costs. We then estimated the overlap between the unique combinations to test potential of the cluster approach for targeting prevention of accumulated disease. We examined variability in the ranks and distributions across age (over/under 65) and deprivation (area level, deciles) subgroups and sensitivity to considering a smaller number of diseases. There were 8,440,133 unique patients in our sample, over 4 million (53.1%) were female, and over 3 million (37.7%) were aged over 65 years. No clear "high cost" combinations of multimorbidity emerged as possible targets for intervention. Over 2 million (31.6%) patients had 63,124 unique combinations of multimorbidity, each contributing a small fraction (maximum 3.2%) to current-year or 5-year secondary care costs. Highest total cost combinations tended to have fewer conditions (dyads/triads, most including hypertension) affecting a relatively large population. This contrasted with the combinations that generated the highest cost for individual patients, which were complex sets of many (6+) conditions affecting fewer persons. However, all combinations containing chronic kidney disease and hypertension, or diabetes and hypertension, made up a significant proportion of total secondary care costs, and all combinations containing chronic heart failure, chronic kidney disease, and hypertension had the highest proportion of preventable emergency admission costs, which might offer priority targets for prevention of disease accumulation. The results varied little between age and deprivation subgroups and sensitivity analyses. Key limitations include availability of data only from hospitals and reliance on hospital coding of health conditions.

CONCLUSIONS

Our findings indicate that there are no clear multimorbidity combinations for a cluster-targeted intervention approach to reduce secondary care costs. The role of risk-stratification and focus on individual high-cost patients with interventions is particularly questionable for this aim. However, if aetiology is favourable for preventing further disease, the cluster approach might be useful for targeting disease prevention efforts with potential for cost-savings in secondary care.

141 Diet supplementation alters oocyte lipid content and developmental competence in mares

The equine oocyte is dense in lipids, which may serve as an energy source for oocyte maturation and later embryonic development. However, the association between lipid content and fertility remains to be determined, as does the extent that diet can modify oocyte lipids. We hypothesised that diet supplementation can alter the oocyte lipid profile and subsequent developmental potential. In Study 1, we examined if oocyte triglyceride (TG) relative abundance was affected by dietary supplementation. Mares (16–22 years, n=9) were fed grass/alfalfa hay and supplemented daily with a combination of commercially available feed additives designed to promote equine wellness and fertility [Equine GI™ (147g daily), Potency® (28g daily), Motility Plus® (23g daily), Healthy Weight Oil (60mL daily), Platinum Performance Inc.]. Oocytes were collected from the mares before (PRE) and after ≥8 weeks (POST) of supplementation during the natural breeding season. In Study 2, we compared oocyte developmental potential after injection of sperm into oocytes obtained from mares supplemented for ≥8 weeks with the same additives (ADD, 18–24 yr, n=5) or from a similar group of mares supplemented with a grain control diet (450g of grain mix and 60ml of corn oil daily, GRN, 19–23 years, n=5). Oocytes were collected from dominant follicles (≥35mm) during oestrus and at 20±2 h after induction of follicular maturation. In Study 1, oocytes were denuded of cumulus cells after collection, snap frozen, and assessed for TG composition by nontargeted liquid chromatography-mass spectrometry using an Acquity UPLC system (Waters). In Study 2, recovered oocytes were placed in maturation medium for 22±2h before being injected with sperm from one stallion, and blastocyst formation was assessed in 7 or 8 days. A total of 100 annotated TG species were identified. Normalized peak areas for PRE and POST oocyte TG were compared using two-tailed, paired t-tests. Blastocyst development rates were compared by Fisher’s exact test. Relative abundance of 71 TG species differed (P ≤ 0.05) between PRE and POST; all TG species as well as total relative abundance of TG were higher in oocytes from PRE compared with POST. Blastocyst rates per sperm-injected oocyte were greater (P=0.03) for ADD (40%, 6/15) than for GRN (5%, 1/19). Dietary supplementation of the complex mix of nutrients to middle-aged and older mares resulted in reduced relative abundance of TG in oocytes and improved developmental potential. We determined that oocyte lipid content can be modified through diet. The extent that diet supplementation improved oocyte competence by altering the lipid profile is still to be determined.

The patient at the centre: evidence from 17 European integrated care programmes for persons with complex needs

BACKGROUND

As the prevalence of multi-morbidity increases in ageing societies, health and social care systems face the challenge of providing adequate care to persons with complex needs. Approaches that integrate care across sectors and disciplines have been increasingly developed and implemented in European countries in order to tackle this challenge. The aim of the article is to identify success factors and crucial elements in the process of integrated care delivery for persons with complex needs as seen from the practical perspective of the involved stakeholders (patients, professionals, informal caregivers, managers, initiators, payers).

METHODS

Seventeen integrated care programmes for persons with complex needs in 8 European countries were investigated using a qualitative approach, namely thick description, based on semi-structured interviews and document analysis. In total, 233 face-to-face interviews were conducted with stakeholders of the programmes between March and September 2016. Meta-analysis of the individual thick description reports was performed with a focus on the process of care delivery.

RESULTS

Four categories that emerged from the overarching analysis are discussed in the article: (1) a holistic view of the patient, considering both mental health and the social situation in addition to physical health, (2) continuity of care in the form of single contact points, alignment of services and good relationships between patients and professionals, (3) relationships between professionals built on trust and facilitated by continuous communication, and (4) patient involvement in goal-setting and decision-making, allowing patients to adapt to reorganised service delivery.

CONCLUSIONS

We were able to identify several key aspects for a well-functioning integrated care process for complex patients and how these are put into actual practice. The article sets itself apart from the existing literature by specifically focussing on the growing share of the population with complex care needs and by providing an analysis of actual processes and interpersonal relationships that shape integrated care in practice, incorporating evidence from a variety of programmes in several countries.

Patients with multimorbidity, partners and other informal caregivers, professionals, payers and policymakers.

MAIN OUTCOME MEASURES

Preferences of participants regarding outcomes of integrated care described as health/well-being, experience with care and cost outcomes, that is, physical functioning, psychological well-being, social relationships and participation, enjoyment of life, resilience, person-centredness, continuity of care and total costs. Each outcome had three levels of performance.

RESULTS

5122 respondents completed the DCE. In all countries, patients with multimorbidity, as well as most other stakeholder groups, assigned the (second) highest preference to enjoyment of life. The patients top-three most frequently included physical functioning, psychological well-being and continuity of care. Continuity of care also entered the top-three of professionals, payers and policymakers in four countries (AT, DE, HR and HU). Of the five stakeholder groups, preferences of professionals differed most often from preferences of patients. Professionals assigned lower weights to physical functioning in AT, DE, ES, NL and NO and higher weights to person-centredness in AT, DE, ES and HU. Payers and policymakers assigned higher weights than patients to costs, but these weights were relatively low.

CONCLUSION

The well-being outcome enjoyment of life is the most important outcome of integrated care in multimorbidity. This calls for a greater involvement of social and mental care providers. The difference in opinion between patients and professionals calls for shared decision-making, whereby efforts to improve well-being and person-centredness should not divert attention from improving physical functioning.

New integrated care models in England associated with small reduction in hospital admissions in longer-term: A difference-in-differences analysis

Closer integration of health and social care services has become a cornerstone policy in many developed countries, but there is still debate over what population and service level is best to target. In England, the 2019 Long Term Plan for the National Health Service included a commitment to spread the integration prototypes piloted under the Vanguard `New Care Models' programme. The programme, running from 2015 to 2018, was one of the largest pilots in English history, covering around 9 % of the population. It was largely intended to design prototypes aimed at reducing hospital utilisation by moving specialist care out of hospital into the community and by fostering coordination of health, care and rehabilitation services for (i) the whole population ('population-based sites'), or (ii) care home residents ('care home sites'). We evaluate and compare the efficacy of the population-based and care home site integrated care models in reducing hospital utilisation. We use area-level monthly counts of emergency admissions and bed-days obtained from administrative data using a quasi-experimental difference-in-differences design. We found that Vanguard sites had higher hospital utilisation than non-participants in the pre-intervention period. In the post-intervention period, there is clear evidence of a substantial increase in emergency admissions among non-Vanguard sites. The Vanguard integrated care programme slowed the rise in emergency admissions, especially in care home sites and in the third and final year. There was no significant reduction in bed-days. In conclusion, integrated care policies should not be relied upon to make large reductions in hospital activity in the short-run, especially for population-based models.

98 Effects of maternal age on oxygen consumption of oocytes and invitro-produced equine embryos

Mitochondrial replication is arrested during early cleavage stages, leaving the embryo dependent on maternally derived mitochondria for oxidative phosphorylation. Numbers of mitochondrial DNA (mtDNA) are used as indicators of functional mitochondria; however, direct comparisons for mtDNA and oxygen consumption rate (OCR) have not been performed for horses. The objectives of this study were to compare equine oocyte mtDNA copy numbers with a measure of mitochondrial function (OCR) and to determine whether maternal age of the oocyte donor impacts OCR of early-stage embryos. We hypothesised that (1) OCR in oocytes is not directly associated with mitochondrial numbers and (2) aerobic metabolism (OCR) is lower in early embryos from old than from young mares. Mares ages 6-13 years (Young, n=7) and=20 years (Old, n=8) were used as oocyte donors. Oocytes were collected from dominant follicles (=35mm) during oestrus and at 16±2h after induction of follicular maturation. Recovered oocytes were incubated in tissue culture medium 199 with 10% fetal calf serum, 25mgmL−1 of gentamicin, and 0.2mM pyruvate for 26±2h. Metaphase II oocytes (Young, n=14; Old, n=15) were fertilized by intracytoplasmic sperm injection (ICSI) using frozen-thawed sperm from one stallion. Presumptive zygotes were cultured in global medium (LifeGlobal Group). Other oocytes and early embryos were used for OCR. A microchamber containing an electrochemical sensor was used to measure OCR from individual oocytes (Young, n=9; Old, n=14) and early embryos (Young, n=8; Old, n=10). After analyses, oocytes were snap frozen, and mtDNA was later quantified by qPCR. Metabolic assays of embryos that cleaved were performed at Day 2 after ICSI. After the assay, embryos were placed back to culture until blastocyst formation at Day 7 or 8. Two-tailed Student's t-tests were used for OCR and mtDNA comparisons, and Fisher's exact tests were used to compare development rates. We found that OCR was higher (P=0.007) for oocytes from Young (mean±s.e.m.: 1.8±0.2) than from Old (1.3±0.1 fmol s−1). However, mtDNA numbers were not different (P=0.3) for Young (5.6±0.4×105) and Old (6.2±0.4×105). Cleavage rates were similar (P=0.6) between Young (11 out of 14, 79%) and Old (13 of 15, 87%). Day 2 embryos from Young had higher basal OCR compared with Old (3.8±0.1 and 3.2±0.2 fmol s−1, respectively; P=0.05). Blastocyst rates per cleaved oocytes were similar for Young (5 of 11, 45%) and Old (4 of 13, 31%; P=0.7). Lower OCR was observed in oocytes and early embryos from Old, which indicates that mitochondrial metabolic function is reduced for mitochondria originating in the oocytes of Old compared with Young. Use of mtDNA was not indicative of mitochondrial metabolic function. Although sample numbers were limited, cleavage and blastocyst development were not significantly different between Young and Old. Further developmental competence was not determined, although the compromised metabolic capacity of oocytes and embryos from old mares could ultimately contribute to lower fertility outcomes.

Implementing a national diabetes prevention programme in England: lessons learned

Background

Type 2 diabetes mellitus is preventable through lifestyle intervention. Diabetes prevention programmes (DPPs) aim to deliver prevention-based behaviour change interventions to reduce incidence. Such programmes vary from usual primary care in terms of where, how, and by whom they are delivered. Implementation is therefore likely to face new commissioning, incentive and delivery challenges. We report on the implementation of a national DPP in NHS England, and identify lessons learned in addressing the implementation challenges.

Methods

In 2017/18, we conducted 20 semi-structured telephone interviews covering 16 sampled case sites with the designated lead(s) responsible for local implementation of the programme. Interviews explored the process of implementation, including organisation of the programme, expectations and attitudes to the programme, funding, target populations and referral and clinical pathways. We drew on constant comparative methods to analyse the data and generate over-arching themes. We complemented our qualitative data with a survey focused on variation in the financial incentives used across sites to ensure usual primary care services recruited patients to new providers.

Results

We identified five over-arching areas of learning for implementing this large-scale programme: 1) managing new providers; 2) promoting awareness of services; 3) recruiting patients; 4) incentive payments; and 5) mechanisms for sharing learning. In general, tensions appeared to be caused by a lack of clear roles/responsibilities between hierarchical actors, and lack of communication. Both local sites and the national NHS coordination team gained experience through learning by doing. Initial tensions with roles and expectations have been worked out during implementation.

Conclusions

Implementing a national disease prevention programme is a major task, and one that will be increasingly faced by health systems globally as they aim to adjust to demand pressures. We provide practical learning opportunities for the wider uptake and sustainability of prevention programmes. Future implementers might wish to define clear responsibilities for each actor prior to implementation, ensure early engagement with new providers, offer mechanisms/forums for sharing learning, generate evidence and provide advice on incentive payments, and prioritise public and professional awareness of the programme.

Digital Health Transformation of Integrated Care in Europe: Overarching Analysis of 17 Integrated Care Programs

Background

Digital health tools comprise a wide range of technologies to support health processes. The potential of these technologies to effectively support health care transformation is widely accepted. However, wide scale implementation is uneven among countries and regions. Identification of common factors facilitating and hampering the implementation process may be useful for future policy recommendations.

Objective

The aim of this study was to analyze the implementation of digital health tools to support health care and social care services, as well as to facilitate the longitudinal assessment of these services, in 17 selected integrated chronic care (ICC) programs from 8 European countries.

Methods

A program analysis based on thick descriptions—including document examinations and semistructured interviews with relevant stakeholders—of ICC programs in Austria, Croatia, Germany, Hungary, the Netherlands, Norway, Spain, and the United Kingdom was performed. A total of 233 stakeholders (ie, professionals, providers, patients, carers, and policymakers) were interviewed from November 2014 to September 2016. The overarching analysis focused on the use of digital health tools and program assessment strategies.

Results

Supporting digital health tools are implemented in all countries, but different levels of maturity were observed among the programs. Only few ICC programs have well-established strategies for a comprehensive longitudinal assessment. There is a strong relationship between maturity of digital health and proper evaluation strategies of integrated care.

Conclusions

Notwithstanding the heterogeneity of the results across countries, most programs aim to evolve toward a digital transformation of integrated care, including implementation of comprehensive assessment strategies. It is widely accepted that the evolution of digital health tools alongside clear policies toward their adoption will facilitate regional uptake and scale-up of services with embedded digital health tools.

Effects of non-medical health coaching on multimorbid patients in primary care: a difference-in-differences analysis

Background

Health systems, globally, are attempting to strengthen primary care to promote a population-health management approach to care provision, incentivising prevention and self-management. This paper evaluates the "Enhanced Primary Care" model implemented in a geographical region in England. Enhanced Primary Care introduces a new non-medical role, health coaches, to the traditional primary care team to provide additional support for patients with chronic conditions. We evaluate effects of health coaching on patient outcomes using a quasi-experiment.

Methods

We estimate the programme’s effects on health status (EQ-5D-5L, physical functioning, psychological wellbeing, and resilience), health behaviour (smoking habit), experience of care (person-centeredness and continuity of care), and health care (primary care) utilisation using data from 3.5 million respondents to the national GP Patient Surveys between 2013 and 2017.

We use a weighted difference-in-differences design to compare changes in outcomes over time between intervention practices and comparable control practices in the rest of England. We conduct our main analysis on multimorbid patients and additional analysis on all patients to assess population-level effects.

Results

For multimorbid patients, we find reductions in psychological wellbeing (short and medium term) of −0.0174 (95% confidence interval −0.0283 to −0.0065), relative difference −2% from the pre-intervention mean; and person-centeredness (short term) of −0.0356 (−0.0530 to −0.0183), −4%. We find no significant effects on other outcome measures. For population-level effects, in the short term we find reductions in primary care utilisation of −0.0331 (−0.0448 to −0.0214), −5%. All other outcomes are not consistently statistically significant.

Conclusions

Our results show that there is very little effect of health coaching on patient experience and outcomes in the short-to-medium term (up to 14 months). Introduction of Enhanced Primary Care was associated with slightly lower psychological wellbeing and person-centeredness amongst multimorbid patients (it might be initially difficult for patients to adjust to the model). However, it was also associated with a decline in primary care visits at the population-level (potentially freeing up practitioner time for more complex patients). The results raise important questions regarding primary care workforce changes advocated in the NHS Long Term Plan, and the time horizon of any benefits of prevention strategies.

Development and Validation of the FSIQ-RMS: A New Patient-Reported Questionnaire to Assess Symptoms and Impacts of Fatigue in Relapsing Multiple Sclerosis

OBJECTIVES

A new patient-reported outcome (PRO) instrument to measure fatigue symptoms and impacts in relapsing multiple sclerosis (RMS) was developed in a qualitative stage, followed by psychometric validation and migration from paper to an electronic format.

METHODS

Adult patients with relapsing-remitting multiple sclerosis (RRMS) were interviewed to elicit fatigue-related symptoms and impacts. A draft questionnaire was debriefed in cognitive interviews with further RRMS patients, and revised. Content confirmation interviews were conducted with patients with progressive-relapsing multiple sclerosis (PRMS) and relapsing secondary-progressive multiple sclerosis (RSPMS). Psychometric analyses used data from adult patients with different RMS subtypes and matched non-RMS controls in a multicenter, observational study. After item reduction, the final instrument was migrated to a smartphone (eDiary) and usability was confirmed in interviews with additional adult RMS patients.

RESULTS

The qualitative stage included 37 RRMS, 5 PRMS, and 5 RSPMS patients. Saturation of concepts was reached during concept elicitation. Cognitive interviews confirmed that participants understood the instructions, items, and response options of the instrument-named FSIQ-RMS-as intended. Psychometric validation included 164 RMS and 74 control patients. Internal consistency and test-retest reliability were demonstrated. The symptoms domain discriminated along the RMS symptom-severity continuum and between patients and controls. Patients were able to attribute fatigue-related symptoms to RMS. Usability and conceptual equivalence of the eDiary were confirmed (n = 10 participants).

CONCLUSIONS

With 7 symptom items and 13 impact items (in 3 impacts subdomains: physical, cognitive and emotional, and coping) after item reduction, the FSIQ-RMS is a comprehensive, valid, and reliable measure of fatigue-related symptoms and impacts in RMS patients.
