Background: Ambulatory geriatric rehabilitation (AGR) is a prevention program for multimorbid patients with the contractual agreement to prevent the need for care and hospital admissions and to promote self-sufficiency. It provides an opportunity to reduce the prevalence of polypharmacy and to discontinue potentially inadequate medication (PIM).

Aim: The study investigated the effect of AGR on the number of drugs and PIM.

Material And Methods: The observational longitudinal study was based on claims data from the statutory health insurance AOK Nordost. A comparison of the prescribed drugs with the PRISCUS list was performed. The study investigated the effect of AGR on the number of drugs prescribed and PIM in the period of two quarterly periods before and two quarterly periods after AGR. The numbers of prescribed statins, opioids, antidementia drugs, proton pump inhibitors and antidepressants were assessed and grouped into further prescriptions, new prescriptions and discontinued drug prescriptions.

Results: Out of 699 participants 682 (73% women, mean age 79 years, SD ± 5 years) were analyzed. The number of substances and PIM remained at the same levels after AGR. Psycholeptic, antiphlogistic and psychoanaleptic drugs were the most frequently prescribed PIM. The majority of statins, opioids, antidementia drugs, proton pump inhibitors and antidepressants were prescribed further. Antidementia drugs were the medication with the most newly started prescriptions.

Conclusion: The AGR has no influence on the number of prescribed drugs and PIM. A structured drug review and a conversation with the general practitioner should be strengthened to improve drug safety and reduce polypharmacy as well as undertreatment.

Background: Evidence on antidementia drugs (ADD) use in developing countries, where accessibility to ADD is challenging, is limited. Our aim was to examine prescribing patterns, factors, and outcomes associated with the early-ADD use (within 3 months from diagnosis) in people with dementia.

Methods: A retrospective cohort study included individuals aged ≥ 60 years with dementia from three hospitals in Thailand between 2015 and 2020.

Article Synopsis
  • Plant extracts are complex mixtures, and this complexity challenges scientists in pharmacological and clinical research, particularly with ginkgo biloba leaf extract.
  • A narrative review highlights ginkgo biloba's composition and clinical evidence for treating Alzheimer's disease, noting its approval as a medicinal product in various regions.
  • While ginkgo biloba extract EGb 761 is well-researched and shows promise against cognitive decline, its exact mechanism of action remains unclear, and clinical study results vary.

Article Synopsis
  • Delirium is a problem that often affects older people in hospitals, and it might increase the chances of them getting dementia later on.
  • A study looked at over 261,000 patients in Osaka to see how delirium during hospital stays is related to the development of dementia.
  • The results showed that people who experienced delirium had dementia show up much faster compared to those who didn't, highlighting the need to prevent delirium and watch for cognitive decline in these patients.

Background: Antipsychotic and other psychotropic medication use is prevalent among community-dwelling older adults with dementia despite the potential for adverse effects. Two Centers for Medicare & Medicaid Services (CMS) initiatives, the National Partnership to Improve Dementia Care ("the Partnership") and the Five Star Quality Rating System for antipsychotic use reporting, have been successful in reducing antipsychotic use in nursing home residents. We assessed if these initiatives had a spillover effect in antipsychotic and other psychotropic medication use among community dwellers with dementia due to potential overlap in prescribers across settings.
