Real-World Metastatic Renal Cell Carcinoma Treatment Patterns and Clinical Outcomes in The Netherlands.

The number of treatment options for patients with metastatic renal cell carcinoma (mRCC) has significantly grown in the last 15 years. Although randomized controlled trials are fundamental in investigating mRCC treatment efficacy, their external validity can be limited. Therefore, the efficacy of the different treatment options should also be evaluated in clinical practice. We performed a chart review of electronic health records using text mining software to study the current treatment patterns and outcomes. mRCC patients from two large hospitals in the Netherlands, starting treatment between January 2015 and May 2020, were included. Data were collected from electronic health records using a validated text mining tool. Primary endpoints were progression-free survival (PFS) and overall survival (OS). Statistical analyses were performed using the Kaplan-Meier method. Most frequent first-line treatments were pazopanib (n = 70), sunitinib (n = 34), and nivolumab with ipilimumab (n = 28). The overall median PFS values for first-line treatment were 15.7 months (95% confidence interval [95%CI], 8.8-20.7), 16.3 months (95%CI, 9.3-not estimable [NE]) for pazopanib, and 6.9 months (95% CI, 4.4-NE) for sunitinib. The overall median OS values were 33.4 months (95%CI, 28.1-50.9 months), 39.3 months (95%CI, 29.5-NE) for pazopanib, and 28.1 months (95%CI, 7.0-NE) for sunitinib. For nivolumab with ipilimumab, median PFS and median OS were not reached. Of the patients who finished first- and second-line treatments, 64 and 62% received follow-up treatments, respectively. With most patients starting on pazopanib and sunitinib, these real-world treatment outcomes were most likely better than in pivotal trials, which may be due to extensive follow-up treatments.

Geriatric characteristics and the risk of drug-related hospital admissions in older Emergency Department patients.

PURPOSE: Drug-Related Admissions (DRAs) are a well-known problem among older patients in the Emergency Department (ED). The aim of this study was (a) to investigate the prevalence and clinical manifestations of DRAs and the responsible drugs, (b) to study the association between geriatric characteristics and DRAs, and (c) to study the predictive performance of geriatric screeners for identifying DRAs in older ED patients. METHODS: Patients aged ≥ 70 hospitalized from the ED were included. Demographics, geriatric characteristics and medications were collected. The the Acutely Presenting Older Patient (APOP)-screener, the Identification of Seniors At Risk (ISAR) and the ISAR-Hospitalized Patients (ISAR-HP) were used as geriatric screeners. Potential DRAs were identified retrospectively, the association between geriatric screeners and DRAs was investigated with logistic regression and the predictive performance was assessed by calculating the Area under the Curve (AUC) of the Receiver Operator Characteristics (ROC). RESULTS: The mean age of patients was 78 (IQR 73-83), using an average of 6 medications. Out of 240 admissions, 77 (30%) were classified as a DRA. Independent risk factors for DRAs were polypharmacy (OR 2.42; 95% CI 1.23-4.74) and the ADL dependency (OR 1.23; 95%CI 1.05-1.44). ISAR (OR 3.27; 95%CI 1.60-6.69) and ISAR-HP (OR 1.83; 95% CI 1.02-3.27) associated with increased risk of DRAs, whereas the APOP screener did not (OR 1.56; 95% CI 0.82-2.97). The predictive performance of all geriatric screeners for predicting DRAs was poor (AUC for all screeners < 0.60). CONCLUSION: DRAs are highly prevalent in older ED patients. Polypharmacy, ADL dependency and a high ISAR or ISAR-HP are associated with higher risk for DRAs, but the predictive value of geriatric screeners is insufficient.

Prevalence of medication transfer errors in nephrology patients and potential risk factors.

BACKGROUND: Medication reconciliation in transitions of care can prevent medication transfer errors (MTE). MTE can cause patient harm. Since performing medication reconciliation for every patient is not always feasible, identification of potential risk factors of MTE could aid in targeting this intervention to the right patients. OBJECTIVE: To establish the proportion of patients with one or more MTE in the outpatient nephrology setting. Secondary patient characteristics associated with MTE, type and potential harm, and medication groups were investigated. METHODS: This retrospective observational cohort study was conducted in the Leiden University Medical Center, the Netherlands, between November 2017 and April 2018. The cohort involved patients in whom medication reconciliation was performed by a medical attendant using the electronic tool 'Medical Dashboard' prior to visiting the nephrologist. MTE were defined as unintended discrepancies between the medication in the hospital system and the result of the medication reconciliation. The proportion of patients with one or more MTE was calculated and the association of patient characteristics (age, sex, number of medications and kidney function (CKD-EPI)) with MTE was analyzed using multivariate logistic regression. RESULTS: Of 380 patients, 235 patients (61.8%) had at least one MTE. On average patients used 10.3 medications. The number of medications per patient was significantly associated with MTE; OR 1.11 (95%CI 1.05-1.16). No association was found for age, sex, and kidney function. CONCLUSION: In ambulatory nephrology patients 61.8% had at least one MTE. Nephrology patients using a higher number of drugs are more prone to MTE.
