Baseline data on registry name, primary sponsor category, intervention type, study phase, study design, randomization status and inclusion criteria for gender of participants are presented in Table 1.
There is no category A evidence and only family interventions meet category B criteria according to the NICE-guidelines [ 19- 22].
In all categories interventions were conducted either face-to-face, via telephone calls or using a combination of these methods.
We classified the type of interventions into three categories; Interventions to structure or standardise clinical practice, geriatric specialist services and influenza vaccination.
If there are discrepancies between reviewers for documenting this information, we will use group consensus among our team to finalise QI categories, interventions and their components.
Based on process evaluation results, IHHP interventions fall into 3 categories: Interventions that can be integrated into the cooperating organizations without carrying additional burdens in terms of financial or human resources.
7 11 We extracted the following information from the included systematic reviews: disease categories, interventions compared, outcomes measured, number of trials and patients, and results of trials included in meta-analyses.
Each set of four community categories (intervention year 4/year 1, control year 4/year 1) was given its own distribution and covariance matrix.
In addition, we shall carry out a logistic regression analysis taking the groups as dependent variable (the target variable is a categorical variable with two categories: Intervention and Control) and the collected measures as independent variables.
In the single intervention category, only educational interventions with self-management approaches, post-discharge home visits and telephone follow-up were found to have significant effects on readmissions.
