ObjectivesCharacterize the prevalence and impact of crying and tearfulness as symptoms that may be suggestive of pseudobulbar affect (PBA) in residents of nursing facilities, including those with Alzheimer's disease (AD) and non-AD [non-AD-associated] associated dementia.DesignData were extracted retrospectively from a large repository of de-identified and linked Minimum Data Set 2.0 (MDS) and prescription claims records for the period between October 1, 2009, and September 30, 2010. A score of 1 or 2 on MDS item E1m ("crying, tearfulness") was used to identify potential PBA.Setting19,000 nursing facilities in 48 states.Patients/ParticipantsPrescription and MDS records of nursing facility residents.Main Outcome MeasuresComparison of concomitant diagnoses, MDS mood, and behavioral indicators, and psychopharmacologic medication use, in residents with crying/tearfulness to a control group matched for age, gender, diagnosis of AD or non-AD dementia, and diagnosis of depression.ResultsA total of 137,829 residents underwent at least one MDS assessment during the study period. Of these, 12,595 (9.1%) had item E1m ("crying, tearfulness") scored as a 1 or 2 on their MDS assessments. Ten thousand residents were then randomly selected from this group and matched to 10,000 controls without "crying, tearfulness" (MDS E1m = 0) for analysis. A total of 4,786 (47.9%) unique residents with "crying, tearfulness" had a diagnosis of AD (8.8%), non-AD dementia (31.5%), or both (7.6%). All of the MDS mood indicators were at least twice as prevalent in this group compared with those without "crying, tearfulness" Additionally, mood symptoms such as anger, worried/pained facial expressions, and repetitive verbalizations; and behavioral symptoms such as verbal/physical abuse and socially inappropriate/disruptive behavior, were more than twice as frequent in the "crying, tearfulness" group. Antipsychotic medications were also used more often in this group (50% vs. 36.1%), as were antidepressants (59.1% vs. 49.8%).ConclusionsIn the absence of an International Classification of Diseases 9th edition, Clinical Modification code, the presence of "crying, tearfulness" on MDS 2.0 item E1m was used as a proxy to identify potential PBA. Nursing facility residents with "crying, tearfulness" had a higher prevalence of all mood and behavior indicators as well as psychopharmacological medication use, compared with matched controls without "crying, tearfulness." Similar results were seen in the subgroup of residents with an underlying diagnosis of AD and/or non-AD dementia. Further research should validate the actual prevalence of PBA in this population, and the corresponding impact on resident outcomes.
