Background The Southern Arizona VA Health Care System (SAVAHCS) implemented a delirium prevention and treatment protocol in 2019. Objective The primary objective of this study was to determine if the implementation of a delirium protocol influenced deliriogenic medication use in hospitalized geriatric veterans. The secondary objectives were to compare the rates of delirium diagnosis, hospital length-of-stay, and rates of newly started deliriogenic medications during admission pre- and post-protocol. Methods This study was a retrospective, secondary data analysis study. Veterans 65 years of age and older who were admitted to an inpatient medical ward at the SAVAHCS for 24 hours or more between January 1, 2018 and December 31, 2018 (pre-protocol) or January 1, 2021 and December 31, 2021 (post-protocol) were included. Patients were excluded if they had a diagnosis of alcohol or benzodiazepine withdrawal upon admission. Results A total of 5491 patients were included in this study; 2940 (53.5%) in the pre-protocol group and 2551 (46.5%) in the post-protocol group. Patients received at least one deliriogenic medication during their admission in the post-protocol group (36.2%) compared with the pre-protocol group (34.1%), but there was no statistically significant difference (P = 0.098). There were also no significant differences in the rates of documentation of delirium as a diagnosis at discharge, hospital length-of-stay, or the rates of newly started deliriogenic medications during admission between the groups. Conclusion Implementation of a delirium prevention and treatment protocol at the SAVAHCS did not significantly impact the use of deliriogenic medications in hospitalized geriatric veterans.

The 2023 update of the American Geriatrics Society Beers Criteria® provides a comprehensive set of guidelines for optimizing medication use in older people. While this update is based on a rigorous review of evidence from clinical trials and research studies published between 2017 and 2022, its application in low- and middle-income countries (LMICs) may present unique challenges and considerations. LMICs often face different health care realities compared with high-income countries, such as limited access to medications, varying prescribing practices, and resource constraints. As a result, the Beers Criteria® 2023 update, which includes the addition, deletion, and revision of medicines based on new evidence, may not be entirely applicable or feasible in these settings. This commentary aims to explore the implications of the 2023 Beers Criteria® update for LMICs, highlighting the need for context-specific adaptations and strategies to optimize medication use and improve health outcomes for older people in resource-limited settings.

Dementia is a disease most prevalent in the older adult population. The cognitive symptoms of dementia include impairments in problem-solving, memory, and language. Some patients experience noncognitive symptoms in addition to the cognitive symptoms of dementia. These noncognitive symptoms are called behavioral and psychological symptoms of dementia or BPSD. The primary objective of our study was to examine the therapeutic options, guidelines, and clinical considerations for the management of BPSD. The existing literature about BPSD was reviewed with searches in PubMed, MEDLINE, and online search platforms. Dysregulation of neurotransmission involving acetylcholine, dopamine, and serotonin has been shown to cause behavioral and psychological symptoms of Alzheimer's disease. BPSD can include hallucinations, agitation, delusions, anxiety, apathy, abnormal body movements, irritability, depression, disinhibition, and sleep or appetite changes. Pharmacologic therapies used in the treatment of BPSD include antidepressants, antipsychotics, anxiolytics, and anticonvulsants. Treatment can be tailored to the specific noncognitive symptoms that are experienced. The use of these agents may be limited based on recommendations from the Beers Criteria®, STOPP criteria, treatment guidelines, and FDA warnings.

Background In older inpatients, anticholinergic medications can increase the risk of complications that may increase length of stay (LOS). Cyclobenzaprine is an anticholinergic medication associated with mental status changes, falls, and injuries in older patients. Objective The purpose of this study is to determine whether use of a lower cyclobenzaprine dose (5 mg) compared with higher dosing (10 mg) will affect LOS, 30-day readmission rates, and need for injectable psychotropic agents in inpatients 65 years of age and older. Methods This was a retrospective cohort analysis comparing outcomes in patients 65 years of age and older who received either a 5 mg or 10 mg cyclobenzaprine dose during their inpatient admission over a 2.5-year period. The primary outcome was hospital LOS, adjusted using multivariate linear regression. Secondary outcomes included 30-day readmission rate adjusted using logistic regression and use of injectable antipsychotics or benzodiazepines. A sub-analysis evaluated the impact of the institution's implementation of a geriatric prescribing context (GEM-CON) on cyclobenzaprine dose selection. Results The adjusted LOS was 32.7% longer (95% CI 25.9%-39.9%) for patients exposed to higher-dose cyclobenzaprine. Use of injectable antipsychotics or benzodiazepines was also significantly greater in the higher-dose group (P < 0.001; P = 0.025). Cyclobenzaprine dose was not significantly associated with readmission on multivariate analysis (OR = 0.93, 95% CI 0.45-1.93). After GEM-CON implementation, there was a significant increase in use of the recommended lower cyclobenzaprine dose (P < 0.001). Conclusion Use of lower cyclobenzaprine dosing in older inpatients is associated with reduced hospital LOS and need for injectable antipsychotics and benzodiazepines.

Parkinson's disease (PD) is a debilitating condition that affects 1.8% of people 65 years of age and older. Patients with PD often require hospitalization and are frequently admitted through the emergency department (ED). Notably, their hospital durations tend to be lengthier compared with patients without PD. The primary outcome of this research was to compare the length of stay (LOS) of patients who received carbidopa-levodopa (CL) in the ED with those who did not. Secondary outcomes included 30-day-readmission rates and administration of injectable for agitation. In addition, the percentage of patients receiving CL before and after an information management technology (IMT) alert implementation was compared in a sub-analysis. Patients that received CL during their inpatient stay were identified by a database report in this retrospective study. Patients were excluded if they were not admitted through the ED, younger than 65 years of age, or admitted to the intensive care unit after the ED. There was a total of 266 in the control group and 217 patients in the intervention group. The intervention group had a significantly shorter LOS than the control group (3.29 vs 5.37 days; P = 0.002), significantly less frequent 30-day readmissions (P = 0.032), and used fewer injectables for agitation (P = 0.035). The sub-analysis of the IMT alert revealed that prior to the alert's implementation, 28.5% of patients received CL in the ED; whereas post-alert, this percentage increased to 91.4% (P < 0.001). The results of this study found that the group of PD patients who received CL in the ED had shorter LOS, lower 30-day readmissions, and used less injectables for agitation compared with the group that did not receive CL in the ED. This improvement is possibly due to continuity of CL supply considering its short half-life and clinical importance for PD.

The objective of this analysis is to investigate the risk of hyperkalemia in hospitalized patients using sulfamethoxazole-trimethoprim (Co-trimoxazole) and a potassium-sparing drug (potassium-sparing diuretic or renin-angiotensin system [RAS]-inhibitor). Researchers conducted a nested case control study within a cohort of hospitalized patients using a potassium-sparing diuretic and/or a RAS-inhibitor from the PHARMO Database Network. Researchers estimated the odds ratios (ORs) and 95% confidence intervals (CI) for the risk of hyperkalemia in patients receiving both Co-trimoxazole and a potassium-sparing drug compared with patients only receiving a potassium-sparing drug. Among a cohort of 25,849 patients, researchers identified 2054 cases of hyperkalemia during hospitalization in patients also using a potassium-sparing drug. Using Co-trimoxazole in addition to a potassium-sparing drug was associated with an increased risk of hyperkalemia in hospitalized patients (ORadj = 1.65, 95% CI 1.26-2.16) compared with using only a potassium-sparing drug. There was a trend of a more pronounced association between hyperkalemia and the co-use of Co-trimoxazole and potassium-sparing drugs in patients with an estimated GFR of 15-29 mL/min (ORadj = 3.15, 95% CI 1.29-7.70). The number needed to harm for hyperkalemia induced by adding Co-trimoxazole to patients receiving a potassium-sparing drug is 19.5. Using the combination of Co-trimoxazole with a potassium-sparing drug in hospitalized patients increases the risk of hyperkalemia compared with using only a potassium-sparing drug. Physicians and other prescribers should be aware of hyperkalemia and routinely monitor serum potassium levels in hospitalized patients using this combination of drugs.
