RESUMEN
INTRODUCTION: Fragmentation of health care across systems can contribute to mistakes in prescribing and filling medications among patients treated for myocardial infarction (MI). We sought to compare omissions, duplications, and delays in outpatient medications used for secondary prevention among veterans treated for MI at Veterans Affairs (VA) versus non-VA hospitals. METHODS: We utilized national VA and Centers for Medicare and Medicaid Services data (2012-2018) to identify veterans 65 years or older hospitalized for MI and measured the use of outpatient medications for secondary prevention in the 30 days after MI among those treated at VA versus non-VA hospitals. RESULTS: A total of 118,456 veterans experiencing MI were included; of which 102,209 were hospitalized at non-VA hospitals. An omission in any medication class occurred more frequently among veterans treated at non-VA versus VA hospitals (82.8% vs 67.8%, P < 0.001). In multivariable modeling, the odds of omissions in any medication class were higher among those treated at non-VA versus VA hospitals (odds ratio: 3.04; 95% CI: 2.88-3.20). Duplications occurred more frequently in veterans treated at non-VA versus VA hospitals: 1.9% versus 1.6% had 1 or more for non-VA versus VA hospitals ( P < 0.001). Veterans treated at non-VA hospitals were more likely to have delays of 3 days or more in prescription fills after hospital discharge (88.4% vs 70.6% across all classes, P < 0.001). CONCLUSIONS: Omissions, duplications, and delays in outpatient prescribing of secondary prevention medications were more common among 118,456 veterans treated at non-VA versus VA hospitals for MI. Interventions aimed at improving care transitions and optimizing medication use among veterans treated at non-VA hospitals should be implemented.

PURPOSE/BACKGROUND: A weight-based dosing approach of 20-30 mg/kg per day of valproic acid (VPA) has been shown to achieve rapid attainment of mood symptom control. Due to interindividual pharmacokinetic variability, therapeutic drug monitoring may be a useful tool to avoid VPA toxicity. Limited research exists on the impact of patient body weight on VPA pharmacokinetic profiles. This analysis aims to explore the correlation between steady-state serum levels of VPA and weight-based dosing strategies, including total body weight (TBW), ideal body weight (IBW), and adjusted body weight (AdjBW), between obese and nonobese patients. METHODS/PROCEDURES: This single-center, retrospective, observational cohort analysis evaluated weight-based dosing of VPA in obese and nonobese patients admitted to inpatient psychiatry at a large academic medical center between July 1, 2017, and July 1, 2022. FINDINGS/RESULTS: This analysis included 93 obese and 93 nonobese patients. No significant difference in median VPA serum concentrations was observed between groups (P = 0.82). However, the obese group received a lower median weight-based dose (15.6 mg/kg) compared with the nonobese group (19.5 mg/kg, P < 0.001). A stronger correlation was found between VPA dose and therapeutic serum levels in the obese group compared with the nonobese group regardless of weight-based dosing strategy. Dosing with AdjBW in obese patients most closely approximated dosing with TBW in nonobese patients. IMPLICATIONS/CONCLUSIONS: In obese patients, our analysis suggests dosing VPA using AdjBW may be considered as the preferred dosing strategy over IBW or TBW to minimize toxicity risk. Further research is needed with larger sample sizes and diverse patient populations to confirm these findings.
RESUMEN
Non-Hispanic Black patients are disproportionally affected by multiple myeloma (MM) and whether efficacy outcomes after autologous stem cell transplant (ASCT) differ by race and ethnicity remains an area of active investigation. This study included 449 patients enriched with a large proportion of non-Hispanic Black patients and sought to highlight the impact of race and ethnicity on outcomes after HDT-ASCT for patients with newly diagnosed MM. We found induction chemotherapy followed by high-dose therapy-ASCT and maintenance chemotherapy is associated with long-term PFS and OS, regardless of race or ethnicity.

AIM: To perform a meta-analysis comparing real-world medication adherence to sodium-glucose cotransporter-2 inhibitors (SGLT2is) versus glucagon-like peptide-1 receptor agonists (GLP-1RAs). MATERIALS AND METHODS: A systematic search of Medline and Embase was conducted through October 2023. To meet inclusion criteria, articles had to be published in full text form and directly compare medication adherence to SGLT2is versus GLP-1RAs in adults. Only studies evaluating real-world data and utilizing the proportion of days covered (PDC) to measure adherence were included. Non-adherence, defined as the proportion of patients with a PDC <80%, was the primary outcome. A subgroup analysis evaluating results among studies conducted in the United States was performed. RESULTS: We identified eight studies evaluating 205 103 patients for inclusion. The most common country from which the data was derived was the United States (n = 5 studies). Upon meta-analysis, we observed no difference in non-adherence (i.e. PDC <80%) to SGLT2is versus GLP-1RAs (relative risk = 0.86; 95% confidence interval = 0.72-1.02). In the analysis, including only US studies, SGLT2i use was associated with a 23% lower risk of non-adherence compared with GLP-1RA use (relative risk = 0.77; 95% confidence interval = 0.72-0.82). CONCLUSIONS: In this meta-analysis of eight studies that included approximately 200 000 patients, there was no difference in adherence to SGLT2is versus GLP-1RAs. However, SGLT2i use was associated with higher adherence when the analysis was limited to US studies.
RESUMEN
INTRODUCTION: There remains a need to determine whether certain subgroups of newly diagnosed multiple myeloma (NDMM) derive the same benefit from high-dose chemotherapy-autologous stem cell transplant (HDT-ASCT). We describe our institutional experience highlighting the impact of age, obesity, and renal impairment on outcomes after HDT-ASCT for patients with NDMM in a real-world setting. METHODS: A total of 449 consecutive patients were included in this retrospective analysis. RESULTS: No difference in median progression free survival or overall survival was seen for patients with age > 65, body mass index (BMI) > 30â kg/m2, or estimated glomerular filtration rate < 60â mL/min/1.73â m2 when compared to those without these characteristics. From a safety standpoint, there were no differences in the incidence of transplant-related mortality or secondary malignancy among subgroups. CONCLUSION: For patients with NDMM undergoing HDT-ASCT, there is no difference in outcomes based on age, BMI, or renal function, and the presence of one or more of these factors should not preclude patients from HDT-ASCT.
RESUMEN
OBJECTIVE: Postoperative delirium has many consequences and should be prevented when possible. Non-opioid pain treatments have known delirium prevention benefits, while melatonin has promising prevention data in non-surgical populations. The incidence of postoperative delirium was retrospectively compared in patients prescribed acetaminophen with and without melatonin following orthopedic surgery. METHODS: Retrospective data was analyzed in adults ≥65-years-old who were hospitalized within one health system following an orthopedic procedure. Patients receiving at least acetaminophen 1000 mg/day with and without melatonin 1 mg/day for at least 48 hours perioperatively were included. Patients were excluded if they had prior delirium, an intensive care unit placement >24 hours, or other risk factors for developing delirium to reduce confounders. The primary outcome was delirium incidence or positive CAM-ICU score. Key secondary endpoints included hospital length of stay and 30-day hospital readmission. RESULTS: Two hundred patients were assessed, and 134 patients were included in the analysis (ie, 66 acetaminophen plus melatonin, 68 acetaminophen alone). There was a lower rate of delirium when comparing the combination vs acetaminophen alone (5% vs 25%; P = 0.001). There were no differences in 30-day readmission. Patients taking the combination had a longer length of stay than acetaminophen alone (5 vs 4 days; P = 0.04). CONCLUSION: Geriatric patients taking acetaminophen plus melatonin after orthopedic surgery had a significantly lower risk of delirium than patients receiving acetaminophen alone. Using combination melatonin and acetaminophen before orthopedic surgery is a promising delirium prevention strategy and should be considered in future prospective trials.
RESUMEN
BACKGROUND: This study aimed to evaluate the geographic distribution of United States (US) clinical trial sites utilizedfor guideline changing studies of cholesterol management. METHODS: Randomized trials evaluating pharmacologic interventions for cholesterol treatment and reporting location data (ie, zip code of trial sites) were identified. Location data was abstracted from ClinicalTrials.gov. RESULTS: Half of US counties were over 30 miles from a study site and, social determinants of health were more favorable in counties with versus without clinical trial sites. CONCLUSIONS: Stakeholders such as regulatory bodies andtrial sponsors should incentivize and support infrastructure that would enable a larger number of US counties to be utilized for clinical trial sites. TRIAL REGISTRATION: Not applicable.

BACKGROUND: Dosing variation of subcutaneous unfractionated heparin (UFH) exist for venous thromboembolism prophylaxis (VTEP). OBJECTIVE: The purpose of this study was to compare the safety and effectiveness of thrice-daily (TID) versus twice-daily (BID) administration of UFH during a heparin shortage for VTEP. METHODS: A single-center retrospective analysis was conducted in patients with orders for BID subcutaneous UFH during a heparin shortage from September 1, 2019, to February 4, 2020. These patients were matched to patients with TID subcutaneous UFH orders from January 1, 2019, to May 31, 2019. The primary outcome was the incidence of deep-vein thrombosis or pulmonary embolism confirmed by imaging during hospitalization. The secondary outcome was the incidence of major or clinically relevant nonmajor bleeding events as defined by International Society on Thrombosis and Haemostasis (ISTH) definitions. RESULTS: A total of 277 patients with orders for BID UFH and meeting inclusion criteria were evaluated and matched to patients who received TID UFH. After the exclusion criteria were implemented, 510 patients remained in the TID group. The primary outcome occurred in 4% of patients in the BID group and 3% in the TID group (P = 0.645). Major bleeding or clinically relevant nonmajor bleeding events occurred in 10% of patients in the BID group and 8% in the TID group (P = 0.310). CONCLUSION AND RELEVANCE: There was no difference in effectiveness or safety of TID versus BID subcutaneous UFH for VTEP. During a heparin shortage, transitioning patients to BID UFH for VTEP to conserve supply may be considered.

BACKGROUND: For transplant-eligible newly diagnosed multiple myeloma patients, autologous hematopoietic stem cell transplant followed by maintenance lenalidomide is a standard of care practice. Maintenance lenalidomide dosing practices vary amongst physicians and current literature lacks comparisons on intermittent versus continuous dosing. In this retrospective study, we compared the safety, tolerability, and efficacy of continuous versus intermittent lenalidomide dosing. METHODS: This single-center, retrospective review included 72 patients with multiple myeloma receiving lenalidomide maintenance between 2018 and 2021. The primary objective was to determine the incidence of dose modification, defined as any dosage reduction, delay in treatment, or discontinuation of therapy. The secondary objectives were to determine the incidence of hematological and non-hematological toxicities between the two groups. RESULTS: A total of 58 patients in the continuous group and 14 patients in the intermittent group were included. Fifty-four percent of patients in the continuous group required dose modification versus 30% in the intermittent group. Patients who received continuous dosing appeared to have a higher incidence of adverse events when compared to intermittent dosing with the most common adverse events being neutropenia, fatigue, and rash. Twenty-four patients in the continuous group switched to an intermittent schedule after an adverse event. Of these patients, only 8% required further dose modification. CONCLUSION: The higher incidence of lenalidomide dose modifications in the continuous arm suggests that a majority of patients are not able to tolerate continuous lenalidomide maintenance. A more tolerable option for maintenance may be an intermittent schedule, as reflected by the favorable safety outcomes in this group.

Purpose: Urinary tract infections (UTIs) are one of the most common indications for antimicrobial use in the emergency department (ED). Appropriate empiric selection is crucial to ensure optimal care while limiting broad-spectrum antibiotic use. The primary objective of this study was to evaluate the relationship between patient-specific risk factors and drug resistant urinary pathogens in patients discharged from the ED and followed by Emergency Medicine Pharmacists (EMPs). Methods: This was a single-center, retrospective chart review of adult (≥18 years old) patients with positive urine cultures discharged from the ED. The association between risk factors and pathogen resistance to ≥1 classes of antibiotics was evaluated using multivariate logistic regression. Risk factors included the following: hospitalization within the previous 30 days, intravenous antibiotic use within 90 days, diabetes, clinical atherosclerotic cardiovascular disease, psychiatric disorder, dementia, current antibiotic use for any indication, previous lifetime history of UTIs, indwelling or intermittent catheterization, hemodialysis, previous lifetime history of a urologic procedure, urinary tract abnormality, immunosuppressive disease or medications, current residence in a nursing or rehabilitation facility, and history of a multidrug resistant organism (MDRO). Results: A total of 1018 patients were included. There was an increase in the odds of antibiotic resistance in patients with cystitis and ≥2 risk factors (Odds Ratio [OR] = 1.70, 95% CI = 1.24-2.32). In those with pyelonephritis, there was a non-significant increase in the odds of resistance for those with ≥2 risk factors (OR = 1.83, 95% CI = 0.98-3.42). Patients with pyelonephritis discharged on inappropriate antibiotics were more likely to return to the ED within 30 days (P = .03). Conclusions: For patients with cystitis discharged from the ED, those with ≥2 patient-specific risk factors had significantly increased odds of antibiotic resistance. Patients with pyelonephritis, but not cystitis, who were discharged on inappropriate antibiotics were more likely to return to the ED within 30 days. In conjunction with an EMP culture follow-up program, the identification of risk factors for antimicrobial resistance can be used to design more patient-specific empiric antibiotic selections.
RESUMEN
PURPOSE: There is currently no consensus regarding the necessity of emergency department (ED) glucose reduction to manage hyperglycemia in patients presenting without a hyperglycemic emergency. Known consequences of intravenous (IV) insulin administration include hypoglycemia, hypokalemia, and increased ED length of stay. The primary objective of this study was to assess the impact of IV regular insulin on glucose reduction and ED length of stay in patients presenting to the ED with non-emergent hyperglycemia. Secondary objectives included the characterization of potential adverse events. METHODS: This was a retrospective, observational study of patients ≥18 years who received IV regular insulin and were discharged from the ED at a large academic Trauma Center. Univariate and multivariable regression analyses were utilized to determine if an association existed between IV insulin administration and blood glucose as well as ED length of stay. RESULTS: A total of 405 patients were included in the analysis. An insulin dose >5 units was associated with a greater reduction in blood glucose (difference = 37.4 mg/dL; p < .001) but no difference in ED length of stay relative to ≤5 units. Furthermore, 7.9% of patients developed hypokalemia and 0.4% developed hypoglycemia. CONCLUSION: The use of >5 units of IV regular insulin for the management of isolated hyperglycemia in the ED was associated with a modest reduction in blood glucose and no difference in ED length of stay compared with those that received ≤5 units. However, use of IV insulin for this purpose resulted in a 7.9% occurrence of hypokalemia.

BACKGROUND: Suboptimal medication adherence has been associated with increased resource utilisation and mortality among patients with type 2 diabetes (T2D). Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are becoming increasingly important in the treatment of T2D. However, medications in this class differ considerably in their dosing frequency, which may impact adherence. We sought to perform a meta-analysis to compare adherence to injectable GLP-1RAs dosed once weekly vs once daily in patients with T2D. METHODS: Medline and Scopus were searched from 1/2005 to 7/2020 using keywords and MeSH terms pertaining to adherence and GLP-1RAs. Studies of adults with T2D were included if they compared adherence (as measured by proportion of days covered [PDC]) to injectable GLP-1RAs dosed once weekly vs once daily. A meta-analysis of non-overlapping studies was performed to evaluate the primary outcome of non-adherence, defined as the proportion of patients with a PDC < 80. RESULTS: A total of 7 studies evaluating 75 159 patients (range: 2886-30 097) with T2D were included. The follow-up periods of included studies ranged from 6 to 12 months. Injectable GLP-1RAs dosed once weekly were either dulaglutide, albiglutide or exenatide extended release; while liraglutide was the injectable once daily agent evaluated in all included studies. Upon meta-analysis, once weekly GLP-1RA dosing was associated with an 11% lower risk of non-adherence compared to once daily dosing (risk ratio = 0.89; 95% confidence interval = 0.83-0.95; I2 = 89%). CONCLUSION: Once weekly dosing of injectable GLP-1RAs was associated with better adherence vs once daily dosing among patients with T2D. These findings coupled with the known detrimental consequences of non-adherence suggest that dosing frequency is an important factor to consider when selecting a GLP-1RA.

Background: Similar to teaching certificate programs, which have been incorporated in many pharmacy residencies to improve teaching skills, resident research certificate programs could provide residents with more exposure to biostatistics and research design. However, few research certificate programs have been described. Objective: To assess the impact of a research certificate program on residents' attitude toward, confidence in, and knowledge of research. Methods: A resident research certificate program was created for the 2018-2019 residency class at our institution, which included 33 pharmacy residents (15 postgraduate year-1 [PGY1] and 18 PGY2 residents). The program consisted of 7 sessions aimed at providing residents with research training. To earn a certificate, participants were required to attend 6 or more sessions and achieve a score greater than or equal to 70% on a postassessment. An optional questionnaire assessing attitude, confidence, and knowledge was also administered at baseline and following the certificate program. Results: Of the 33 residents participating in the research certificate program, 21 (9 PGY1 and 12 PGY2) residents completed both the baseline and follow-up questionnaire and were included in the analysis. All items assessing attitude and 3 of 6 items assessing confidence improved significantly following the certificate program when compared to baseline (P < .05 for all). Median knowledge scores were no different on the baseline versus follow-up questionnaire (P = .54). Conclusions: After completing a research certificate program, resident knowledge scores did not differ from baseline, but attitudes toward research and confidence appeared to improve. Research certificate programs could be an avenue for providing pharmacy residents with increased exposure to and comfort with biostatistics and research design.
RESUMEN
The number of adults with heart failure (HF) will increase by ~50% between 2012 and 2030. Among kidney transplant recipients, HF accounts for 16% of all post-transplant admissions. We describe the burden of HF and predictors of healthcare utilization following kidney transplantation. We retrospectively identified adults who underwent kidney transplantation at our institution (01/2007-12/2017). Data were acquired from electronic health records, with healthcare utilization obtained from a statewide database. The HF incidence rate and prevalence were estimated for each year, total charges for HF and non-HF patients were compared, and logistic regression was employed for a 3-year predictive model of healthcare utilization associated with HF. Among 1731 kidney transplant recipients, the post-transplant HF incidence rate ranged from 1.91 (year 3) to 6.80 (year 10) per 100 person-years, while the prevalence increased from 31.7% (year 1) to 48.1% (year 10). Median charges were $75 837 (HF) compared to $42 940 (non-HF) per person-year (P < 0.001). Pretransplant HF [odds ratio (OR) = 3.12] and an eGFR < 45 (OR = 4.73) were the strongest predictors of HF encounters (P < 0.05 for both). We observed a high and increasing prevalence of HF, which was associated with twice the costs. Kidney transplant recipients would benefit from interventions aimed at mitigating HF risk factors.

BACKGROUND: Cardiovascular (CV) disease is the leading cause of death among United States women. Rural residence and ethnic-minority status are individually associated with increased CV mortality. Managing dyslipidemia is important in the prevention of CV mortality. However, the impact of race/ethnicity and location of residence on sex differences in dyslipidemia management is not well understood. Therefore, we sought to understand the joint effects of race/ethnicity and location of residence on lipid management differences between veteran men and women with type 2 diabetes (T2D). METHODS: Veterans Health Administration and Centers for Medicare and Medicaid Services data were used to perform a longitudinal cohort study of veterans with T2D (2007-2016). Mixed effects logistic regression with a random intercept was used to model the association between sex and low-density lipoprotein (LDL) > 100 mg/dL and its interaction with race/ethnicity and location of residence after adjusting for all measured covariates. RESULTS: When female sex and rural location of residence were both present, they were associated with an antagonistic harmful effect on LDL. Similar antagonistic harmful effects on LDL were observed when the joint effect of female sex and several minority race/ethnicity groups were evaluated. After adjusting for measured covariates, the odds of LDL > 100 mg/dL were higher for urban women (OR = 2.66, 95%CI 2.48-2.85) and rural women (OR = 3.26, 95%CI 2.94-3.62), compared to urban men. The odds of LDL > 100 mg/dL was the highest among non-Hispanic Black (NHB) women (OR = 5.38, 95%CI 4.45-6.51) followed by non-Hispanic White (NHW) women (OR = 2.59, 95%CI 2.44-2.77), and Hispanic women (OR = 2.56, 95%CI 1.79-3.66). CONCLUSION: Antagonistic harmful effects on LDL were observed when both female sex and rural location of residence were present. These antagonistic effects on LDL were also present when evaluating the joint effect of female sex and several minority race/ethnicity groups. Disparities were most pronounced in NHB and rural women, who had 5.4 and 3.3 times the odds of elevated LDL versus NHW and urban men after adjusting for important covariates. These striking effect sizes in a population at high cardiovascular risk (i.e., older with T2D) suggest interventions aimed at improving lipid management are needed for individuals falling into one or more groups known to face health disparities.

Several real-world studies have evaluated adherence to direct acting oral anticoagulants in patients with non-valvular atrial fibrillation (NVAF); however, these studies have not been systematically summarized. We performed a meta-analysis to compare adherence to rivaroxaban versus dabigatran therapy in United States (US) patients with NVAF in a real-world setting. Medline and Scopus were searched from January 2010 to August 2018 using keywords and MeSH terms related to adherence and oral anticoagulants. We included real-world studies of US adults with NVAF comparing adherence to dabigatran and rivaroxaban. Studies evaluating adherence by a measure other than proportion of days covered (PDC) were excluded. The proportion of patients with a PDC ≥ 80 (a commonly utilized definition of adherence) served as the primary outcome of interest. We conducted meta-analysis of non-overlapping studies using the Hartung-Knapp random-effects model to estimate risk ratios (RRs) with corresponding 95% confidence intervals (CIs). We included 5 studies evaluating 80,230 patients (range 2667-22,571). Median follow-up across studies was 6 months (range 3-12 months). The proportion of patients with a PDC ≥ 80 ranged from 59.5 to 83.5% for rivaroxaban users and 57.3 to 78.3% for dabigatran users. Upon meta-analysis, rivaroxaban use was associated with increased adherence compared with dabigatran use (RR 1.08; 95% CI 1.03-1.12; I2 = 88%). In conclusion, rivaroxaban was associated with increased adherence when compared to dabigatran in ~ 80,000 patients in a real-world setting. Possible explanations for this include dosing frequency or patient tolerance.

PURPOSE: There is conflicting evidence to support the superiority of weight-based (WB) dosing of intravenous (IV) diltiazem over non-weight-based (NWB) dosing strategies in the management of atrial fibrillation (AFib) with rapid ventricular response (RVR). METHODS: A retrospective review evaluated patients presenting to the emergency department (ED) in AFib with RVR and receiving IV diltiazem from 2015 to 2018. Those receiving a NWB dose were compared with those receiving a WB dose based on actual body weight (ABW). Secondary analyses evaluated safety profiles of the regimens and compared response in groups defined by ABW or ideal body weight (IBW). RESULTS: A total of 371 patients were included in the analysis. No significant difference was observed in achieving a therapeutic response (66.5% vs. 73.1%, p = 0.18) or adverse events between the groups. Patients receiving a WB dose were significantly more likely to have a HR < 100 bpm than those receiving a NWB dose (40.9% vs. 53.5%, p = 0.01). When groups were defined by IBW, WB dosing was associated with a significantly higher incidence of achieving a therapeutic response (62.7% vs. 74.3%, p = 0.02). CONCLUSION: In patients presenting with AF with RVR, there was no significant difference in achieving a therapeutic response between the two strategies. A WB dosing approach did result in a greater proportion of patients with a HR < 100 bpm. The utilization of IBW for WB dosing may result in an increased achievement of a therapeutic response.

INTRODUCTION: Despite first-line approval in metastatic renal cell carcinoma (mRCC), the tyrosine kinase inhibitor cabozantinib is associated with frequent treatment-limiting side effects. Dose reductions in published trials of the drug and in clinical practice are commonplace. We analyzed our institution's real-world experience with cabozantinib dosing in patients with mRCC to assess strategies to improve tolerability and patient outcomes. OBJECTIVES: The purpose of our study is to retrospectively analyze dose intensity, tolerability, and duration of exposure in mRCC patients who received cabozantinib at our institution. METHODS: In this retrospective, single-center chart review, we identified 35 adult patients who received at least one cycle cabozantinib for mRCC during a two-year period. Dosing patterns were reviewed for each patient to allow calculation of median dose intensity and median duration of exposure. RESULTS: The median dose intensity for cabozantinib was 55.4% and the median actual daily dose was 33.2 mg. Median duration of cabozantinib exposure was 10.4 months. Several alternative dosing strategies were employed with 60% of patients requiring at least one dose intervention to manage toxicities. CONCLUSIONS: Patients in this analysis received a median actual daily dose of 33.4 mg, less than the reported median doses in the METEOR and CABOSUN trials. However, our median duration of cabozantinib treatment was 10.4 months compared to 8.3 months and 6.5 months in these respective trials. Further investigation is warranted to determine if alternative dosing strategies and lower median actual daily doses produce survival results comparable to published clinical trials.

Reducing acute care utilization is a means of improving long-term patient outcomes. We sought to assess high inpatient (IP) admission and standalone emergency department (ED) utilization within a 9-month period post-kidney transplantation and to identify mutable factors to reduce utilization. In this ten-year retrospective study, 1599 adult kidney transplant recipients were identified. A previous transplant, graft loss, or death within 3 months post-transplantation excluded 319 patients. Comprehensive resource utilization data were obtained from a statewide database. Those with ≥2 IP admissions or standalone ED visits 4-12 months post-transplantation were classified as high utilizers. Multivariable logistic regression models were used for examining associations of predictors with high IP or ED utilization. Of 1280 kidney recipients, 209 and 183 were categorized as IP and ED high utilizers, respectively. Factors significantly associated with high IP utilization included valvular disease, body mass index ≥35, and IP or ED use <3 months post-transplantation; while factors associated with high ED utilization included IP or ED use <3 months post-transplantation, younger age, female, smoker, congestive heart failure, depression, and IP or ED use 1 year pre-transplantation. Inpatient and standalone ED utilization within a 9-month period after kidney transplantation is high and associated with sociodemographic factors, mutable comorbidities, and healthcare utilization.

Background: Acute chest syndrome (ACS) is an acute complication of sickle cell disease (SCD). Historically, the most common pathogens were Chlamydophila pneumoniae, Mycoplasma pneumoniae, and respiratory syncytial virus. Pediatric patients receiving guideline-adherent therapy experienced fewer ACS-related and all-cause 30-day readmissions compared with those receiving nonadherent therapy. This has not been evaluated in adults. Objectives: The primary objectives were to characterize antibiotic use and pathogens. The secondary objective was to assess the occurrence of readmissions associated with guideline-adherent and clinically appropriate treatment compared with regimens that did not meet those criteria. Methods: A retrospective cohort analysis was conducted for adults with SCD hospitalized between August 1, 2014, and July 31, 2017, with pneumonia (PNA) or ACS. The study was approved by the institutional review board. Results: A total of 139 patients with 255 hospitalizations were reviewed. Among 41 respiratory cultures, 3 organisms were isolated: Cryptococcus neoformans, Pseudomonas aeruginosa, and budding yeast. Respiratory panels were collected on 121 admissions, with 17 positive for 1 virus; all were negative for Chlamydophila pneumoniae and M pneumoniae. There were significantly more ACS-/PNA-related 7-day readmissions from patients on guideline-adherent regimens compared with nonadherent regimens (3.7% vs 0%; P = 0.04). Conclusion and Relevance: These findings challenge existing knowledge regarding the most common pathogens in adults with SCD with ACS or PNA. Routine inclusion of a macrolide may not be necessary. Future studies focused on pathogen characterization with standardized assessment are necessary to determine appropriate empirical therapy in this population.
