Factors Associated with Acute Injurious Falls in Elderly Hospitalized Patients: A Multicenter Descriptive Study.

BACKGROUND: The Centers for Medicare & Medicaid Services Hospital-Acquired Conditions (CMS-HAC) links Medicare payments to health care quality. Experiencing a serious disability or death associated with a fall in a health care facility based on diagnosis codes has been identified as an opportunity for improvement. Multiple factors contribute to an inpatient fall, including medications that affect cognition in older adults. The primary aim of this study was to investigate the effect of the commonly prescribed classes of medications on the CMS-HAC falls and trauma definition in US hospitals in a large inpatient database from 2019 to 2021. METHODS: The authors analyzed data from 835 hospitals in the Vizient Clinical Data Base between January 1, 2019, and December 31, 2021, on patients ≥ 65 years of age with CMS-HAC patient falls and trauma codes. Using logistic regression and stepwise Poisson regression analysis, the authors identified demographic, clinical, and hospital-related variables associated with falls meeting the CMS-HAC definition. The top 20 prescribed drug classes in these patients were also identified. RESULTS: Among 11,064,024 patient encounters, 5,978 met the CMS-HAC definition of a serious fall. Patients who experienced a serious fall were significantly more likely to be > 79 years of age (p < 0.001, odds ratio [OR] 1.30, 95% confidence interval [CI] 1.23-1.37), have a history of prior falls (p < 0.001, OR 2.30, 95% CI 2.11-2.50), have a code for dementia (p < 0.001, OR 1.50, 95% CI 1.40-1.60), and have higher anticholinergic cognitive burden (ACB) scores (p < 0.001, OR 1.14, 95% CI 1.13-1.14). Specific medication classes associated with CMS-HAC falls were first-generation antihistamines (p < 0.00, OR 1.21, 95% CI 1.09-1.35), second-generation antihistamines (p ≤ 0.001, OR 1.15, 95% CI 1.13-1.19), and atypical antipsychotics (p < 0.001, OR 1.18, CI 1.13-1.29). CONCLUSION: Patients who experience a fall meeting the CMS-HAC fall definition are significantly more likely to have a prior history of falling, dementia, and a higher ACB score. Results from this study may inform future quality improvement work aimed at reducing injurious falls.

National Amoxicillin-Clavulanate Formulation Use Pattern: A Survey.

OBJECTIVE: Five commercially available amoxicillin-clavulanate (AMC) ratio formulations contribute to ratio selection variability with efficacy and toxicity implications. The objective of this survey was to determine AMC formulation use patterns across the United States. METHODS: A multicenter practitioner survey was distributed to multiple listservs (American College of Clinical Pharmacy pediatrics, infectious diseases, ambulatory care, pharmacy administration; American Society of Health-System Pharmacists; Pediatric Pharmacy Association members), and selected pediatric Vizient members in June 2019. Responses were screened for multiples within institutions. Repeated organization responses were identified (n = 37) and excluded if the duplicate matched another response from the same organization exactly (n = 0). RESULTS: One hundred ninety independent responses were received. Nearly 62% of respondents represented a children's hospital within an acute care hospital; remainder being from stand-alone children's hospitals. Around 55% of respondents indicated prescribers were responsible for choosing the patient-specific formulation for inpatients. Nearly 70% of respondents indicated multiple formulations were available due to clinical need (efficacy, toxicity, measurable volume), whereas over 40% responded that the number of liquid formulations were limited to decrease the potential for error. Variability was demonstrated among institutions using ≥ 2 different formulations for acute otitis media (AOM), sinusitis, lower respiratory tract infection, skin and soft tissue infection, and urinary tract infection (33.6%, 37.3%, 41.5%, 35.8%, and 35.8%, respectively). The 14:1 formulation was the most common, but not exclusive, for AOM, sinusitis, and lower respiratory tract infections with 2.1%, 2.1%, and 2.6% of respondents indicating use of the 2:1 formulation and 10.9%, 15%, and 16.6% of respondents indicating use of the 4:1 formulation. CONCLUSIONS: Significant AMC formulation selection variability exists across the United States.

Antimicrobial Stewardship Practice in the Ambulatory Setting From a National Cohort.

BACKGROUND: The majority of antimicrobial use occurs in the ambulatory setting. Antimicrobial stewardship programs (ASPs) are effective in improving appropriate prescribing and are now required by accreditation bodies. METHODS: This was a cross-sectional, multicenter survey describing the current state of ambulatory ASPs in a national cohort of Vizient member hospitals with ambulatory healthcare settings and serves as a benchmark for stewardship strategies related to program effectiveness. RESULTS: One hundred twenty-nine survey responses from a variety of institution types across 44 states were received. Survey respondents reported a fully functioning ASP in 7% (9 of 129) of ambulatory practices compared with 88% (114 of 129) of inpatient institutions. Effectiveness in at least 1 antibiotic use-related outcome (ie, utilization, resistance, Clostridioides difficile infection, or cost) in the past 2 years was reported in 18% (18 of 100) of ambulatory and 84% (103 of 123) of inpatient ASPs. Characteristics of ambulatory ASPs demonstrating effectiveness were institution guidelines (89%, 16 of 18), rapid diagnostic testing for respiratory viruses or group A Streptococcus (89% 16 of 18), outpatient antibiograms (78% 14 of 18), and dedicated pharmacist support (72%, 13 of 18). Ambulatory ASP effectiveness was shown to increase as programs met more of the Centers for Disease Control and Prevention (CDC) Core Elements of Outpatient Antimicrobial Stewardship (P < .001). CONCLUSIONS: Antimicrobial stewardship programs are needed in the ambulatory setting, but they are not common. Currently, few ambulatory ASPs in this survey self-identify as fully functioning. The CDC Core Elements of antimicrobial stewardship should remain foundational for ASP development and expansion.

A prospective assessment of the effect of aminophylline therapy on urine output and inflammation in critically ill children.

BACKGROUND: Aminophylline, an established bronchodilator, is also purported to be an effective diuretic and anti-inflammatory agent. However, the data to support these contentions are scant. We conducted a prospective, open-label, single arm, single center study to assess the hypothesis that aminophylline increases urine output and decreases inflammation in critically ill children. METHODS: Children less than 18 years of age admitted to the pediatric intensive care unit who were prescribed aminophylline over a 24-h period were eligible for study. The use and dosing of aminophylline was independent of the study and was at the discretion of the clinical team. Data analyzed consisted of demographics, diagnoses, medications, and markers of pulmonary function, renal function, and inflammation. Data were collected at baseline and at 24-h after aminophylline initiation with primary outcomes of change in urine output and inflammatory cytokine concentrations. RESULTS: Thirty-five patients were studied. Urine output increased significantly with aminophylline use [median increase 0.5 mL/kg/h (IQR: -0.3, 1.3), p = 0.05] while blood urea nitrogen and creatinine concentrations remained unchanged. Among patients with elevated C-reactive protein concentrations, levels of both interleukin-6 (IL-6) and IL-10 decreased at 24 h of aminophylline therapy. There were no significant differences in pulmonary compliance or resistance among patients invasively ventilated at both time points. Side effects of aminophylline were detected in 7 of 35 patients. CONCLUSION: Although no definitive conclusions can be drawn from this study, aminophylline may be a useful diuretic and effective anti-inflammatory medication in critically ill children. Given the incidence of side effects, the small sample size and the uncontrolled study design, further study is needed to inform the appropriate use of aminophylline in these children.

Palivizumab in congenital heart disease: should international guidelines be revised?

Palivizumab has reduced the incidence of respiratory syncytial virus hospitalization in infants and children with congenital heart disease by 45%. Although the mortality rate of children with congenital heart disease hospitalized with respiratory syncytial virus infection has declined from 37% to approximately 3% over the past 3 decades, palivizumab has not been shown to improve mortality. There has been considerable controversy over the cost-effectiveness of administering palivizumab according to international guidelines, including children with congenital heart disease. In particular, the number of children that need to be treated with palivizumab to prevent one respiratory syncytial virus hospitalization increases dramatically in children > 12 months of age. As a result, the authors recommend that countries re-examine their recommendations for providing palivizumab up to age 24 months in children with congenital heart disease.

Palivizumab: a review of its use in the protection of high risk infants against respiratory syncytial virus (RSV).

Respiratory syncytial virus (RSV) is a leading cause of hospitalization in children less than 1 year of age and causes substantial morbidity. Although there is not currently a vaccine available to prevent RSV infection, prophylaxis with the humanized monoclonal antibody palivizumab has been shown to reduce the rate of RSV hospitalization in premature infants and those infants with chronic lung disease or congenital heart disease. Because palivizumab has not been shown to have a beneficial clinical effect on established RSV disease such as reducing the rate of mechanical ventilation and mortality in children afflicted with RSV, there has been considerable debate as to the cost-benefit ratio of administering palivizumab according to international guidelines. Palivizumab has demonstrated a favorable side-effect profile in clinical trials without the development of anti-palivizumab antibodies. Future studies are needed to determine whether palivizumab, or other more potent monoclonal antibodies which are currently undergoing clinical trials, will reduce the long-term sequelae of RSV infection such as the development of wheezing and asthma.

Administration of the first dose of palivizumab immunoprophylaxis against respiratory syncytial virus in infants before hospital discharge: what is the evidence for its benefit?

BACKGROUND: Palivizumab is 1 of 2 agents used to prevent severe lower respiratory tract disease due to respiratory syncytial virus (RSV) infection. The American Academy of Pediatrics and the American College of Obstetricians and Gynecologists recommend administering the first dose of RSV immunoprophylaxis to eligible infants before hospital discharge. Unfortunately, third-party payers frequently do not separately reimburse administration of this therapy to hospitalized infants. OBJECTIVE: Because palivizumab is commonly used to provide RSV immunoprophylaxis, we systematically reviewed all published data on this drug to determine whether the evidence supports the recommendation of administering the first dose before hospital discharge. METHODS: MEDLINE was searched for all articles published in English from January 1, 1996, to October 31, 2003, using the search terms palivizumab and Synagis, and the following data were extracted onto a standardized form: author(s), year of publication, study design, patient population, sample size, criteria used for administration of RSV prophylaxis, location of palivizumab prophylaxis (inpatient or outpatient), parental satisfaction with administration of prophylaxis, incidence of RSV infection, and hospitalization rates for RSV. All selected publications were reviewed to determine whether they reported differences in the incidence of RSV infection or hospitalization in patients who received palivizumab before discharge compared with those who received it after discharge. Only those publications that specifically documented administration of the first dose of palivizumab before hospital discharge were included in the final analysis. RESULTS: Six of the 166 studies reviewed met the selection criteria. Although all 6 studies reported reduced RSV hospitalization rates with palivizumab prophylaxis, no study directly compared inpatient and outpatient administration with regard to parental satisfaction or rates of RSV infection or hospitalization. Furthermore, based on the data in these studies, it was not possible to detect any differences in parental satisfaction or rates of RSV infection or hospitalization between the 2 locations of administration. CONCLUSIONS: Based on our literature review, there is no evidence to support the recommendation that palivizumab be administered before hospital discharge in every infant who meets the criteria for RSV immunoprophylaxis. Eligible infants may be given the initial dose of RSV prophylaxis as outpatients, reducing the cost to institutions that currently provide palivizumab before hospital discharge.
