{"doi":"10.1093/ageing/afac227","title":"Does polypharmacy shape dependency transitions in the very old? Findings from the Newcastle 85+ Study","abstract":"BACKGROUND: helping older people to maintain their independence, and identifying risk factors that compromise this, is of high importance. Polypharmacy is common in the very old (aged ≥ 85) but whether it can shape transitions in dependency in this fastest growing subpopulation is unclear. METHODS: using Newcastle 85+ Study data and multi-state modelling, we investigated the association between each additional medication prescribed and the progression of and recovery from dependency states, over 10 years (age 85-95). Participants were defined as either free from care (independent), requiring care less often than daily (low dependency), or requiring care at regular intervals each day or 24 hourly (medium/high dependency). RESULTS: each additional medication prescribed was associated with a 10% decreased chance of recovery from low dependence to independence (hazard ratio (HR): 0.90, 95% confidence interval (CI): 0.82-0.99). DISCUSSION: when a relatively able person visits the GP or clinical pharmacist, careful consideration should be given to whether the potential benefits from adding a new medication outweigh the risk to reduced recovery of independence.","journal":"Age and Ageing","year":2022,"id":279727,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":4,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9611,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":18185,"name":"Adam Todd","orcid":"0000-0003-1496-9341","position":1,"is_corresponding":false},{"id":350819,"name":"Louise Robinson","orcid":"0000-0003-0209-2503","position":2,"is_corresponding":false},{"id":578747,"name":"Andrew Kingston","orcid":"0000-0003-4211-7007","position":3,"is_corresponding":false},{"id":953311,"name":"Laurie E.
