341 The Prevalence and Factors Associated with Anti-psychotic Prescribing on Admission to a Dementia Specific Nursing Home (Age and Ageing)

AbstractBackgroundThe use of psychotropic medications and their adverse effects in frail adults has been debated extensively. However, it is unclear if antipsychotics are initiated in a nursing home or if the new resident arrives with the medication prescribed. The purpose of this study is to ascertain how many residents arrive already on antipsychotics and which factors, make them more likely to be on this medication.MethodsAll admission notes to the centre between 1st Jan 2018 and 31st Dec 2018 were reviewed. Inclusion criteria was any person admitted with a diagnosis of dementia. Exclusion criteria was anyone who had psychiatric diagnosis such as bipolar disorder or schizophrenia. We collected data on age, gender, referral pathway (hospital or community), MMSE, Barthel, Cohen Mansfield Agitation Inventory (CMAI) For comparisons of characteristics between the two groups (psychotropic drugs at admission: yes/no), the independent samples t-test (normally distributed data) or the Mann-Whitney U test (non-normally distributed data) was used for continuous variables and Fisher`s exact test was used for categorical variables.ResultsThere was a statistically significant relationship between source of admission and whether or not the patient was receiving psychotropic drugs on admission (p=0.017). 88.0% of patients on psychotropic drugs on admission came from an acute hospital setting. In contrast, only 4.0% of patients receiving psychotropic drugs on admission came from home Patients on psychotropic drugs at admission had higher CMAI scores compared to patients not on psychotropic drugs. Patients on psychotropic drugs at admission were younger (mean(SD): 76.2(8.7) years) than patients not of psychotropic drugs (mean(SD): 82.9(8.3).ConclusionPrevalence of prescribing antipsychotics outside of nursing homes is high with many residents being admitted already on these medications. Efforts should be put in place on admission to nursing homes to reduce and stop antipsychotics which have been initiated in the community and hospital setting.
