Considerable variation exists among anticholinergic risk scales, in terms of selection of specific drugs, as well as of grading of anticholinergic potency. Our selection of 100 drugs with clinically relevant anticholinergic properties needs to be supplemented with validated information on dosing and route of administration for a full estimation of the anticholinergic burden in poly-medicated older adults.
IP (polypharmacy, underuse and misuse) was highly prevalent in adults, aged 80 years and older. Surprisingly, underuse and not misuse had strong associations with mortality and hospitalization.
As in other European countries, the prevalence of psychotropic utilisation in Belgian nursing homes is exceedingly high, with excessive duplicate use. Guidelines, education and clinical practice recommendations focusing on initiation, reassessment and withdrawal of psychotropic therapy, are needed.
AIM:(i)To describe the prevalence of benzodiazepine use in Belgian nursing homes, with specific attention to indications and dosages.(ii)To compare actual and recommended dosages of benzodiazepines for anxiety and insomnia.(iii)To explore the risk profile for chronic benzodiazepine use in institutionalised older adults.
METHODS:Medication charts of 1730 residents from 76 nursing homes in Belgium were collected and analysed, using the ATC classification. Drug name, indication and daily dosage were recorded. From authoritative international sources, we extracted for each drug and each indication a daily dosage recommended not to exceed in older adults, for comparison with observed actual dosages.
RESULTS:Among the chronic BZD/Z users (50% of the residents), the leading indication was 'insomnia' (59% of the users) followed by 'anxiety' (17%) and 'unrest' (10%). In the chronic prescriptions of BZD/Zs indicated for insomnia, the actual daily dose exceeded the geriatric upper limit: with lormetazepam in 95% ,zolpidem in 82%, zopiclone in 78% and lorazepam in 35% of the prescriptions. In anxiety, daily doses also exceeded the limit but not to the same extend.Multivariate analysis showed BZD/Z use was positively associated with pain (OR 1.58 CI95% 1.27-1.97), constipation ) and depression (OR 1.68 CI95% 1.35-2.08). Residents with dementia were less likely of receiving a BZD/Z (OR 0.60 CI95% 0.48-0.74).
CONCLUSION:Efforts to reduce the use of BZD/Zs in nursing homes should concentrate on insomnia, with interventions aimed to reduce too high prevalence of chronic use and too high daily dosages in this indication.3
Nurses and GPs share a very low willingness and high barriers to antipsychotic discontinuation. To implement discontinuation programs, complex multidisciplinary interventions should be offered taking existing barriers into account.
Dealing with the behavioral and psychological symptoms of dementia (BPSD) is often complex. Given the controversy with regard to antipsychotics for behavioral problems in people with dementia, there has been a renewed emphasis on nonpharmacological interventions, with progress in the design of the relevant studies. Potential nonpharmacological interventions for BPSD are: cognitive training/stimulation, rehabilitative care, activities of daily living, music therapy, massage/touch, physical activity, education/training of professionals, and education and psychosocial support of informal caregivers. Use of antipsychotics in the management of BPSD is controversial due to limited efficacy and the risk of serious adverse effects, but credible alternatives remain scarce. The problem of chronic use of antipsychotics in nursing homes should be tackled. Discontinuation of antipsychotic medication in older individuals with BPSD appears to be feasible. Discontinuation efforts are needed to differentiate between patients for whom antipsychotics have no added value and patients for whom the benefits outweigh the risks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
