November, 2016 - SUPPORT Summary of a systematic review | print this article |
Partnerships between health and other public services at a local level have been promoted to improve the health of the population. It is not clear whether such collaboration improves health outcomes.
|Review objectives: To evaluate the effects of interagency collaboration between local health and local government agencies on health outcomes in any population or age group.|
|Type of||What the review authors searched for||What the review authors found|
|Study designs & interventions||Randomised trials , non-randomised trials, controlled before-after studies and interrupted time series studies that assess any interventions of interagency collaboration and partnership and local government agencies||This review included 16 studies: randomised trials (7), non-randomised trials (4), controlled before-after studies (4) and 1 interrupted time series study. 11 studies were included in the meta-analysis. 7 studies reported on interventions to improve the care or treatment of patients and 9 studies about health education, health promotion or disease prevention|
|Participants||All population types and all age groups were included||Studies were delivered through community and primary care services (8 studies), in schools (5 studies), and in the wider community (3 studies).|
|Settings||Any local or national setting||Studies were conducted in UK (7 studies), Denmark (1 study), Sweden (1 study), Norway and Sweden (1 study), the Netherlands (1 study), USA (2 studies), Canada (1 study), Israel (1 study), and Australia (1 study).|
|Outcomes||Mortality, morbidity and behavioural change||A variety of outcomes were reported, including behavioural changes, morbidity and healthcare process|
|Date of most recent search: December 2011|
|Limitations: This is a well conducted systematic review with only minor limitations.|
Hayes SL, Mann MK, Morgan FM, et al. Collaboration between local health and local government agencies for health improvement. Cochrane Database of Systematic Reviews 2012, Issue 10. Art. No.: CD007825.
This review included 16 studies conducted in high-income countries comparing interagency collaboration between local health and local government agencies with standard care or no intervention. Seven studies reported interventions to improve the care or treatment of patients through multidisciplinary team work and 9 studies reported collaborative interventions to improve health education, health promotion or disease prevention in different community settings.
The authors conducted metaanalyses that included 11 studies for which it was possible to combine data. They also conducted a narrative review by type of interventions with studies not included in the metaanalyses. Information from the narrative review has not been included in this summary.
Interagency collaboration between local health and local government agencies compared with standard care
|People: All population types: elderly, children, mothers, patients with psychiatric disorders, etc.
Settings: United Kingdom, Denmark, Sweden, United States, Australia and Norway
Intervention: Different strategies of local collaboration between primary care, education, local public health, city government, community organizations, etc.
Comparison: Standard care
|Outcomes||Impact||Certainty of the evidence
||We are uncertain of the effect of interagency collaboration between local health and local government agencies.
||Very Low||Based on data from 1 cluster randomised trial and 2 non-randomised trials with frail elderly populations|
||We are uncertain of the effect of local interagency collaboration to improve results in mental health in specific populations.||Very Low||Based on data from 4 studies in patients with different psychiatric disorders and 1 in mothers to prevent postpartum depression|
|Physical Health||There may be little or no impact of collaborative strategies on health outcomes.||Low||Based on data from 5 studies in different groups of patients: children with asthma, with obesity, adults with musculoskeletal disorders, and mothers to prevent postpartum depression|
|Quality of life||There may be little no impact of collaborative strategies on quality of life.||Low||Based on data from 3 studies, 2 with patients with asthma and one with elderly patients with dementia|
|Global Assessment of Function symptoms score||Patients with the intervention had on average a slight improvement compared with the control group (MD-2.63, 95% CI -5.16 to -0.10).||Low||Based on data from 2 studies including patients with psychiatric disorders|
GRADE: GRADE Working Group grades of evidence (see above and last page)
MD: mean difference
CI: confidence interval
All studies included in this review were conducted in high income countries.
|The conditions of local agencies in low-income countries is likely very different from those in high-income countries. Results reported in this review should be applied with caution in low-income settings.
|Only two of the 16 studies included in this review focused on deprived populations.||The effects on equity of interventions based on local interagency collaboration will depend on where the intervention is based (schools, primary health centres, community setting). For example, if the intervention is provided in schools, children who don’t attend school will not have access to the intervention, with a detrimental effect on equity for that population.|
|The studies included no direct evidence of the cost or cost effectiveness of local interagency collaboration.
||Coordination between local agencies to develop collaborative interventions could require additional resources that need to be considered before implementing them.
|MONITORING & EVALUATION|
|Good quality data from well-designed studies in low-income countries are not available.||
Cluster randomised trials or interrupted time series studies together with process evaluations should be used to evaluate these interventions in low income countries. These studies should assess the effects of local interagency collaborative interventions on relevant patient outcomes. It is also necessary to assess the cost effectiveness of these interventions.
