1. Interventions for improving outcomes in patients with multimorbidity in primary care and community settings: Systematic review Susan M Smith 1, Hassan Soubhi 2, Martin Fortin 2, Catherine Hudon 2, Tom O'Dowd 3 1 HRB Centre for Primary Care Research, RCSI Medical School, Dublin 2 Department of Family Medicine, University of Sherbrooke, Quebec 3 Department of Public Health and Primary Care, Trinity College Dublin

2. Objective To determine the effectiveness of interventions designed to improve outcomes in patients with multimorbidity in primary care and community settings

3. Method: Cochrane systematic review Studies –RCTs, CCTs, CBAs and ITS Participants –Two or more conditions Interventions –Any intervention designed to improve outcomes in individuals defined as having multimorbidity –Primary care and community settings –EPOC taxonomy

4. Method: Outcomes Physical or mental health Psychosocial –Quality of life, well-being and measures of disability or functional status Patient or provider behaviour –Prescribing, medication adherence, health related behaviours, health services use, goal attainment Acceptability of the service Economic Attitude and knowledge outcomes excluded

5. Results: Search

6. Included studies Ten studies; all RCTs –3407 patients –8 in USA and 2 in UK –Majority 6-12 months –8 included patients with broad range of conditions though elderly –2 focused on co-morbidities Overall minimal risk of bias though consideration of contamination of control patients was generally inadequate

7. Risk bias: generally low

8. Results: Interventions Interventions: –6 organisational –4 patient oriented Multifaceted including : o Case management o Enhanced skill mix in teams o Structured care provision o Patient focussed approaches such as self-care and self-management

10. Results: Outcomes Physical and mental health outcomes mixed PROMs (8 studies) mixed Admissions data (6 studies) mixed Patient health behaviours (4 studies) mixed Medication use and adherence (2 studies) improved Prescribing (2 studies) improved Costs (four studies) – data on direct costs only

11. Results: overview Variation in participants and interventions Co-morbidity vs multimorbidity –Problems with definitions and overlap with frailty –May need different interventions for different groups Timescale –Improvements in medication related measures Targeting risk factors or specific functional difficulties may be more effective

12. Implications: Practice No strong evidence to support any particular intervention as yet Need to consider implications of socioeconomic deprivation and health literacy problems when designing and evaluating interventions Participatory approaches

13. Implications: Research Definition of multimorbidity challenging Searching and labelling: –MeSH term needed Outcomes with focus on physical functioning and quality of life, goal attainment Economic analyses needed

14. Conclusions Limited available evidence with the focus being on co-morbid conditions or multimorbidity in older patients Need for clear definition of participants, and appropriate outcomes Suggestion that interventions may be more effective if targeted at specific risk factors of functional difficulties Need for well-designed intervention studies
