Overview study on integrated care for chronic diseases - 11th February

  1. 1. The effectiveness of interventions to achieve coordinated multidisciplinary care and reduce hospital use for people with chronic diseases Progress to date and methodological challenges
  2. 2. Outline • Background to the ‘overview study’ • Aim and objectives • Selection of outcome measures • Methods and data analysis • Preliminary findings: hospitalisation • Methodological challenges – Double counting of primary studies – Excluding studies on the basis of quality score – Grouping studies with similar interventions
  3. 3. Background • People with chronic diseases often require care crossing multiple health and social care settings • These patients typically experience fragmented and poorly coordinated management of their conditions • There will be a significant increase in the number of patients with chronic diseases in the coming years, and associated increase in costs of management • Government policy increasingly emphasises integrated care and developing new models of delivering healthcare services e.g. Better Care Fund • Yet there is a paucity of evidence about what works, for which patients, in which settings, and for which outcomes
  4. 4. Aim and objectives Aim: To assess the effectiveness of interventions and integrated management models for chronic disease in terms of service provider and patient outcomes Objectives: 1. Describe and review the conceptual frameworks being used to define integrated models of care for chronic disease 2. Describe and evaluate trends in service provision 3. Assess which models or individual elements are particularly effective in delivering improved provider and patient outcomes 4. Identify gaps in the evidence base where further targeted systematic reviews of primary research may be useful
  5. 5. Selection of outcome measures Service providers: • Stakeholder meeting with representatives from each of the Theme 4 case study sites, CCGs and others • Discussion to establish which questions and outcomes are the most important to providers Patients: • Literature review to inform a short survey • List of commonly reported patient outcomes derived and given to patients via CLAHRCWM PPI database • Input from Theme 4 PPI representative
  6. 6. Outcome measures chosen: • Healthcare utilisation: Including (re)admission rates, length of hospital stay, A&E visits, clinic and GP resource use, institutionalisation rates • Costs: Healthcare costs or savings from interventions • Quality of life: Generic or disease specific measures • Patient satisfaction: Impact of interventions or service models on patient satisfaction with care • Care coordination: Interventions or service models which assess the effectiveness of providing care coordination and ‘patient centered’ care
  7. 7. Search strategy Medline Cochrane Library and DARE Medline in Process Health Economics Evaluations Database Applied Social Sciences Index and Abstracts (ASSIA) TRIP database (systematic reviews and evidence synthesis) PsycINFO PROSPERO Health Management Information Consortium Web based searches CINAHL EPPI-Centre Library Embase Reference lists of included papers
  8. 8. Inclusion and exclusion criteria INCLUSION CRITERIA EXCLUSION CRITERIA Published during or since 2000 Reviews with unsystematic methods Published in English language Studies focusing on caregivers Systematic reviews, meta-analysis, narrative reviews Editorials, opinion pieces, commentaries, letters, conference proceedings Comparison group includes usual care, no intervention or other interventions Studies assessing integration in less economically developed countries Adult patients with one or more chronic diseases Palliative or end of life care Assess care models or interventions crossing the boundary between two or more healthcare settings Interventions solely psychosocial or related to spirituality, mindfulness, health literacy or the use of CAM Include data related to one or both provider outcomes and/or one or both patient outcomes Interventions relating solely to lifestyle change or treatment/medication adherence
  9. 9. Study selection • Removal of duplicate records • Two reviewers screen titles and abstracts for relevance • Relevant reviews proceed to full text evaluation • Two reviewers screen full texts for outcomes of interest • Data extraction and quality assessment according to pre-defined forms • For grey literature, relaxation of strict criteria on methodological robustness and systematic methods • All disagreements resolved by discussion or arbitration by a third reviewer if necessary
  10. 10. Data extraction Reference ID Research questions Who delivers the intervention? Citation Study designs included Who co-ordinates the intervention? Country of publication Number of studies included Source of intervention Databases and search years Type of review Length of follow-up Geographical scope Definition of intervention Intervention context Language restriction Study population Primary and secondary outcomes Healthcare setting(s) Number of participants Data on our outcomes of interest Chronic disease(s) General description of intervention Review summary and conclusions Overall aim of review Specific features of intervention Any other information
  11. 11. Quality assessment • Centre for Evidence Based Medicine checklist: 5 questions, total score from 0-5 (5 = high quality) 1. Is the research question clearly stated? 2. Is it unlikely that important, relevant studies were missed? 3. Were the inclusion criteria appropriate? 4. Were included studies sufficiently valid for the type of question asked? 5. Were results similar from study to study?
  12. 12. Records from databases n=10,682 Records from other sources n=11 After duplicate removal n=7,747 Titles and abstracts screened n=7,747 Full text articles assessed n=353 Included reviews n=81 Removal of duplicates n=2,946 Excluded after title and abstract screen n=7,394 Full text articles excluded n=272
  13. 13. Review characteristics • 81 reviews eligible for data extraction • All published between 2004 to 2014 • 45 covered 3+ settings; 2 primary and secondary care, 8 primary and community/social care/home, 24 secondary care and community/social care/home • 22 general chronic disease; 59 covered individual or multiple specific conditions • Number of primary studies ranged from 4 to 560 • 45 narrative reviews, 32 systematic reviews with meta-analysis, 4 reviews of reviews • Interventions highly heterogeneous in design, intensity, duration and outcomes reported
  14. 14. Methodological challenges •Double counting of primary studies •Excluding papers on the basis of quality score •Grouping of interventions
  15. 15. Double counting • 81 reviews include a total of 1293 primary studies • The same primary studies frequently occur in more than one included review • Potentially problematic when synthesising results from multiple reviews on the same intervention • Artificial inflation of effect size and over-estimation of effectiveness of intervention or service model

  18. 18. Potential solutions • In a given intervention category, select only the most recent high quality review and exclude previous reviews (after checking conclusion agreement) • Only include reviews that had RCTs as their primary study design • Include only studies with meta-analyses • Subdivide reviews on a specific intervention by time- band (i.e. 2000-2005, 2005-2010, 2010-present) and analyse change in outcome over time for ‘drift’ in results
  19. 19. Excluding on QA score QA SCORE NUMBER OF REVIEWS 1 3 1.5 7 2 6 2.5 5 3 14 3.5 8 4 20 4.5 5 5 13 • 21 of 81 reviews have QA score less than 3/5 • Real difference in quality at this cut-off point • Very little, if any outcomes data can be extracted from the low scoring reviews • Restrict inclusion to reviews with higher quality evidence?
  20. 20. Grouping interventions • Interventions could be categorised in an almost infinite number of ways and most interventions overlap Professional interventions Financial or regulatory interventions Organisational interventions Provider orientated Professional role change; MD teams; service integration; continuity of care Patient orientated Consumer participation in care governance; self- management e.g. professional education e.g. provider incentives or penalties Structural Changes to setting/site of service delivery; changes in medical record systems 0 studies 0 studies Nearly all included studies have elements of each
