The serum anticholinergic activity (SAA) assay has been used to quantify patients' anticholinergic load. In addition, several ranked lists of anticholinergic drugs have been developed to assess anticholinergic drug burden. ⋯ Scores obtained from ranked lists of anticholinergic drugs were associated with clinically significant anticholinergic ADEs but the SAA was not. This finding supports the usefulness of these lists to help identify patients at risk of anticholinergic ADEs in clinical practice.

Overuse of unnecessary medications in frail older adults with limited life expectancy remains an understudied challenge. ⋯ Very little rigorous research has been conducted on reducing unnecessary medications in frail older adults or patients approaching end of life.

Randomized Controlled Trial
Immunogenicity and safety of a quadrivalent meningococcal serogroups A, C, W-135 and Y tetanus toxoid conjugate vaccine (MenACWY-TT) administered to adults aged 56 Years and older: results of an open-label, randomized, controlled trial.
The burden of invasive meningococcal disease is substantial in older adults in whom the case fatality rate is high. Travelers to regions with high rates of meningococcal disease, such as Hajj pilgrims, are at increased risk of meningococcal infection, and disease transmission from travelers to their close contacts has been documented. In younger individuals, meningococcal conjugate vaccines offer advantages over polysaccharide vaccines in terms of duration of protection and boostability, and induction of herd immune effects through reductions in nasopharyngeal carriage of meningococci. To date, few data are available evaluating meningococcal conjugate vaccine use in adults >55 years of age. ⋯ In adults 56 years of age and older, MenACWY-TT was immunogenic, with a vaccine response rate ≥76 % and with ≥93 % of subjects achieving rSBA titers ≥1:128 against all four serogroups after a single dose. MenACWY-TT induced low anti-TT concentrations in this population, which deserves further study.
