Pain in Patients With Dementia and Behavioural Disturbances

Pain Clinical Trial

Official title: The Impact of Pain on Behavioural Disturbances in Patients With Moderate and Severe Dementia. A Cluster Randomized Trial

Status Completed

Clinical Trial Summary

In nursing homes (NHs) 80% of the patients have dementia, between 60%-80% exhibit behavioural disturbances (BPSD), and more than 60% have pain. Both pain and BPSD is more common in those with severe dementia. Since older persons with dementia have less communicative skills, suffer from more pain and exhibit more agitation, pain may be a contributing factor in these patients. More than 40% of patients with BPSD are treated with neuroleptics despite described side-effects. There is an urgent need to investigate the impact of individual pain management on BPSD in patients with dementia.

It was hypothesized that

• pain increase BPSD in patients with dementia

• individual pain treatment decrease BPSD in patients with dementia

Clinical Trial Description

We intend to conduct an eight weeks, multi-centre, rater-blinded, cluster randomized, and parallel-group trial, with follow up after four weeks. We will choose cluster randomizing by practical reasons. 920 NH patients were screened and 352 patients with moderate or severe dementia and BPSD were included. The treatment period is 8 weeks, with further follow after four weeks.

The primary outcome measure will be reduction in aggression and agitation as well as other items which are measured by means of CMAI (Cohen Mansfield Agitation Inventory). Secondary outcome are reduction in NPI-NH-subscale agitation/aggression and other items which are measured by the Neuropsychiatric Inventory, Nursing Home Version (NPI-NH). Further, we want to evaluate the concomitant use of acute medication. Additionally, Activities of Daily Living function (ADL) and MIni Mental State Examination (MMSE) will be used as secondary outcome measure.

Pain in patients with dementia will be assessed and followed by the MOBID-2 Pain Scale (secondary outcome measure). MOBID-2 Pain Scale is a staff-administered behavioural instrument for assessment pain in older persons with dementia with god validity and reliability (Husebo 2008, 2009). MOBID-2 is based on patient's pain behaviour in connection with standardised, guided movements of different body part, and pain behaviour related to internal organs, head and skin. Additionally, pain will be registered by pain diagnoses, -etiology, and -duration. The MOBID-2 score is derived from caregiver in a clinical bedside situation during morning care.

Adverse events will be recorded and evaluated throughout the study as the primary assessment of safety and tolerability.

Inclusion criteria: Patients of either gender, 60 years of age or older, living in a nursing home (NH) diagnosed moderate or severe dementia measured by the Functional Assessment Staging (FAST) and MMSE, and BPSD in form of agitation / aggression as measured by subscale of NPI-NH and CMAI.

Exclusion criteria: Patients without cognitive impairment and without BPSD. Patients with hepatic or renal failure or diseases that make it impossible to follow the study schedule. ;
