What “Health systems and care delivery” covers

Health systems and care delivery — How health systems organize, coordinate and pay for dementia care, and where and how people with dementia actually receive it.

A note on reading research. One study is rarely the final word.

We try to note the size of a study, whether it was in humans or animals, and how early-stage the finding is. If a summary here doesn't make that clear, treat it with extra caution and check the original source.

Penny-wise but Pound-foolish: The Hidden Costs of Step Therapy for Overactive Bladder

Site of death among individuals with and without dementia in 2016–2018

✓ Peer-reviewed alzhub usefulness score 47 out of 100. Journal of the American Geriatrics Society 2022-02-17

Individuals living with dementia often have limited capacity to express their care preferences at the final stage of life, and therefore, are at risk of receiving end-of-life care that may not align with their preferences.1 While most people prefer to be at home in their final days of life,2 research has shown that individuals with dementia are less likely to die in a home or community setting compared to those without dementia.3, 4 Studies also suggest that the percentage of individuals with dementia who died in a home or community setting has been increasing over time.5, 6 This study sought to update the literature by examining the association between dementia status and site of death, and by comparing the trends in site of death between decedents with and without dementia using recent national data. 5 key findings →

Coverage and Prior Authorization Policies for Semaglutide and Tirzepatide in Medicare Part D Plans

✓ Peer-reviewed alzhub usefulness score 44 out of 100. JAMA Network Open 2025-08-29

This cross-sectional study examines trends in coverage of glucagon-like peptide-1 receptor agonists, semaglutide and tirzepatide, and prior authorization requirements among Medicare Part D beneficiaries. 1 key finding →

Design: cross-sectional Evidence: low

Potentially inappropriate medication (PIM) use-defined as the use of high-risk medications that can increase the risk of adverse events such as physical, cognitive, and functional decline; delirium; hospitalizations; and mortality-remains a significant concern in older adults in the US.Numerous guidelines, including the American Geriatrics Society Beers Criteria 1 and the STOPP criteria, 2 define PIMs as medications for which the risk of adverse effects outweighs potential benefits or are inappropriate for specific populations or disease states, such dementia or kidney disease.PIM use may be particularly harmful in populations experiencing other health care disparities, as communities experiencing other consequences of health care inequity, including limited access to physicians or pharmacies, greater financial stress, and a higher comorbidity burden, may experience disproportionate effects from the adverse consequences of PIM use. 1 key finding →

Evidence: low

Based on physician medical records alone, the 231 high-risk participants (mean age 77, 67% women) received recommended care for 53% of 5,569 evaluated clinical circumstances, ranging from 12% for end-of-life care to 78% for diabetes mellitus. 5 key findings →

How the 0–100 score works — and why some entries are capped

This is alzhub's own score. It is not an official metric, not an impact factor, and no journal, publisher or ranking body endorses it. We built it so that a reader who is not a scientist can tell a landmark trial from a conference abstract without having to already know the difference. Every point comes from one of 20 components, all of them printed on the study itself, so you can disagree with our arithmetic rather than having to trust the total.

Journals are placed in ordered tiers, never given a numeric impact factor — we could not verify current impact factors from a source we control, and an invented one would be worse than none. Tier 1 is the top-tier general journals (NEJM, The Lancet, JAMA, Nature, Science, Nature Medicine); tier 2 is the leading specialty journals; tier 3 is every other peer-reviewed journal. A separate part scores how much the journal's own papers are cited, which tells the tier-3 journals apart.

Two rules we don't bend. First, we never fill in a missing value: if a record does not state a sample size or a design, that component scores zero, and if we simply have no data for a part, such as a citation count, that part is left out and the study is scored on the parts we could check. The study card says which. Second, anything that is not a peer-reviewed article is capped at 16/100 and carries a warning chip — so a conference abstract or a company press release can never outrank a peer-reviewed paper, no matter how good it looks.

We rank a rigorous null result — a good trial showing that something does not work — above an early positive finding. Someone deciding whether to buy a supplement is served by that, and the rigour is already counted by the design and journal components.

The score is computed from the published data alone and is reproducible: the same file always yields the same numbers.

See the whole rubric drawn out → — four charts covering all 31,380 studies: how the scores are spread and where the cap bites, which of the 20 components the library is strong and weak on, which subjects rest on stronger evidence, and what kinds of study each subject is actually built from.

What this library is — and isn't

This is a large sample of the Alzheimer's literature, not an exhaustive index of it. It holds 31,380 records, built mostly from automated pulls of Europe PMC (65.6% of the library) and OpenAlex (16.2%), plus smaller pulls from PubMed, Crossref and medRxiv. If a study, a drug, or a finding isn't here, that is not evidence it doesn't exist in the literature — it may simply not have been pulled in yet.

1,048 records (3.3% of the library) are not peer-reviewed — 973 of those are preprints posted before any journal review, and the rest are conference abstracts, regulatory notices and reports. Every study card on this page states its status plainly, and the score above is capped for anything that isn't a peer-reviewed article.
