ISRCTN ISRCTN23325295
DOI 10.1186/ISRCTN23325295
ClinicalTrials.gov identifier
EudraCT number
Public title Disease manifestation and disease management in chronic heart failure
Scientific title A standardised multidisciplinary disease management programme improves mortality and morbidity in patients with systolic heart failure - the Interdisciplinary Network for Heart failure (INH) Study
Acronym INH-Study
Serial number at source N/A
Study hypothesis Network care when compared to usual care reduces mortality and hospitalisation (combined primary end point) and/or improves quality of life 6 months after randomisation.

On 20/08/2009 the following changes were made to the trial record:
1. Scientific title was added
2. Target number of participants was changed from 700 to 1,000
3. Trial end date was updated from 31/12/2006 to 30/09/2009
4. Randomised intervention extended to 18 months
All other changes are recorded in the relevant fields.

On 17/04/2014 the following changes were made to the trial record:
1. The follow-up period was extended to 36 and 60 months
2. The anticipated end date was changed from 30/09/2009 to 31/12/2019
3. The target number of participants was changed from 1,000 to 1,022

Target number of participants 1,022
Interventions This is a 2-arm parallel group randomised intervention study. Patients are randomised 1:1 into network care and usual care. Intensified patient care and management (i.e. network care) is characterised by:
1. Telephone based symptom-oriented patient monitoring following a predefined algorithm depending on the severity of the condition
2. Telephone based patient-oriented education and training regarding heart failure manifestation, diet, psychological dimensions
Primary outcome measure(s) Current primary outcome measure as of 20/08/2009:
1. Death of any cause or hospitalisation of any cause (combined endpoint)

Previous primary outcome measures:
1. Death of any cause or hospitalisation of any cause (combined endpoint)
2. Quality of life
Secondary outcome measure(s) Current secondary outcome measures as of 20/08/2009:
1. Components of composite primary endpoint
2. Cardiovascular death
3. Cardiovascular hospitalisation
4. Proportion of patients treated in adherence with current heart failure treatment guidelines
2. Quality of life
5. Cost-effectiveness analyses

Previous secondary outcome measures:
1. Components of composite primary endpoint
2. Cardiovascular death
3. Cardiovascular hospitalisation
4. Proportion of patients treated in adherence with current heart failure treatment guidelines
5. Cost-effectiveness analyses
Sources of funding 1. German Federal Ministry of Education and Research (Bundesministerium Für Bildung und Forschung [BMBF]).
2. Head Organisation of non-private health insurances (Spitzenverbände der gesetzlichen Krankenkassen).

Added on 24/08/2009: Additional funding was received from the German Competence Network Heart Failure for the 'extended INH-Study' in 2006 and 2009.
