NPTDA - Northwick Park Therapy Dependency Assessment

The Northwick Park Therapy Dependency tool provides an assessment of patient’s therapy dependency. It is a measure of therapy intervention designed for use in specialist neuro-rehabilitation settings, where high intensity rehabilitation is provided by a multi-disciplinary team. The NPTDA includes 30 items of therapy dependency in 7 domains; Physical handling programme, basic functions, activities of daily living, cognitive/psychosocial/family support, discharge planning, indirect interventions and additional activities, special facilities, investigations and procedures.

The NPTDA is recommended as part of the NIHR dataset for Level 1 and Level 2 services. Completion of the tool is more time consuming than the RCS or Barthel index and is suggested that it be completed fortnightly in a MDT meeting but maybe pre-prepared by the lead discipline for each item to speed up the process. The therapy dependency assessment tool is part of the parallel tranche data and should be collected at the same time as the nursing dependency score. For more information about the parallel data tranches please contact a member of the UKROC team.

The score given for each therapeutic intervention reflects both direct patient contact time in relation to the task and time spend away from the patient e.g. preparing material, writing up clinical notes from treatment sessions. The computer outputs include an overall dependency score, calculation of total therapy time per patient bu individuals.
