Comparative Effectiveness Research on Psychiatric Hospitalisation by Record Linkage of Large Administrative Data Sets – CEPHOS-LINK

Funded by the European Commission, 7th Framework Program
Participating countries: Austria, Finland, Italy, Norway, Romania, Slovenia
Project number: 603264

Duration: April 2014 – March 2017, currently dissemination and post-project data analysis phase

Psychiatric services have undergone profound changes over the last decades. Large mental hospitals were downsized or closed and community mental health services set up, in order to move treatment of patients from institutions to the community. However, little is known about the effectiveness of this “de-institutionalisation” approach. In fact, psychiatric hospital admission and re-admission rates are still high in most countries, and it is only little understood why. Since repeated hospital admissions constitute profound interruptions in patients’ lives and are feared by patients because of stigma, their decrease can be regarded as a patient centred outcome (PCO); also, unplanned readmissions are not regarded as an indicator of efficiency and good quality of care.

CEHPOS-LINK will make use of record linkage methods in data sets of large administrative electronic health care databases in six European countries with different health care systems (Austria, Finland, Italy, Norway, Romania and Slovenia), for exploring in routine settings the relationship between a large array of factors (on the patient, service and health system level) and rehospitalisation of psychiatric patients who were discharged from hospital, and to compare the outcome of several naturally occurring service use patterns. Cost-effectiveness issues will be dealt with.

Given the use of data from multiple databases in six countries, work on data availability, acquisition, management, quality, interoperability, privacy protection and linkage methods will precede local and pooled data analyses, performed with statistical methods and innovative dynamic modelling approaches. Views from users and carers, cost-effectiveness aspects and findings from systematic reviews of the literature will be integrated with results of the record linkage studies for producing guidelines, recommendations and decision support tools for decision makers in the field of mental health system and services interventions.
