Background: Guidelines advise 50 % and 25 % dose reduction of the therapeutic nadroparin dose (86 IU/kg) in patients with eGFR 15-29 and 30-60 ml/min respectively. For monitoring, peak anti-Xa levels are suggested. Data lack whether this results in therapeutic anti-Xa levels or in anti-Xa levels that are comparable to those of patients without renal impairment.

Article Synopsis
  • - Vancomycin is an essential antibiotic for treating serious infections like MRSA, but it needs careful monitoring to avoid side effects and ensure effectiveness due to its narrow therapeutic range.
  • - Researchers developed a quick and efficient method using UPLC-MS/MS to measure vancomycin and creatinine in dried blood spots (DBS), which is less invasive than traditional blood sampling.
  • - The validation showed that this method can accurately measure the drug and creatinine levels with high precision and minimal errors, making it suitable for clinical use.

Background: Unintentional changes to patients' medicine regimens and drug non-adherence are discovered by medication reconciliation. High numbers of outpatient visits and medication reconciliation being time-consuming, make it challenging to perform medication reconciliation for all outpatients. Therefore, we aimed to get insight into the proportion of outpatient visits in which information obtained with medication reconciliation led to additional drug-related actions.

Background: Adoption of a personal health record (PHR) depends on its usability and perceived usefulness. Therefore, we aimed to assess the usability and perceived usefulness of an online PHR used for medication reconciliation and to assess the association between patient-, clinical-, hospital-, and ICT-related factors and the usability and perceived usefulness at both the in- and outpatient clinics.

Methods: A multicenter cross-sectional study was conducted with patients with either an outpatient visit (rheumatology ward) or planned admission in the hospital (cardiology, neurology, internal medicine or pulmonary wards).

Background: Improving patient's medication knowledge and consequently medication use is essential for optimal treatment outcomes. As patient knowledge about medication is currently suboptimal, interventions to optimise medication knowledge are necessary. Implementation of Patient's Own Medication (POM) in which patients bring their outpatient medication to the hospital, and nurses administer these during admission, may increase medication knowledge.

Article Synopsis
  • The study aimed to assess the prevalence and causes of medication administration errors (MAEs) in two Dutch hospitals to inform prevention strategies.
  • Observational data revealed that 13.7% of medication administrations involved MAEs, with the most common types being omissions and wrong handling, and certain medication forms and times of day showing higher error rates.
  • The findings indicate a significant MAE prevalence, suggesting targeted interventions could help reduce these errors, particularly focusing on specific medication forms and administration times.

Background Personal health records have the potential to identify medication discrepancies. Although they facilitate patient empowerment and broad implementation of medication reconciliation, more medication discrepancies are identified through medication reconciliation performed by healthcare professionals. Aim We aimed to identify the factors associated with the occurrence of a clinically relevant deviation in a patient's medication list based on a personal health record (used by patients) compared to medication reconciliation performed by a healthcare professional.

Aim: Medication discrepancies (MDs), defined as unexplained differences among medication regimens, cause important public health problems with clinical and economic consequences. Medication reconciliation (MR) reduces the risk of MDs, but is time consuming and its success relies on the quality of different information sources. Online personalized health records (PHRs) may overcome these drawbacks.

Background: Poor adherence to antihypertensives is associated with negative outcome of the disease as well as loss of health-care resources. Addressing the epidemic of poor adherence requires identifying factors associated with this behaviour. The aim of this study is to describe adherence to antihypertensive medication among Lebanese hypertensive patients and to evaluate the association between socio-economic, patient- and conditions-related factors and non-adherence.

Within the southern region of the Netherlands, the Maastricht Study is an on-going observational prospective population-based cohort study that focuses on the etiology of Type 2 diabetes mellitus (T2DM). Representativeness of the participating population is a crucial but often an unknown factor in population-based cohort studies such as the Maastricht Study. We therefore aimed to assess the representativeness of the study population by comparing drug utilization of the participants of the Maastricht Study with the general population of the Netherlands.

Background Medication is frequently thrown away after a patient's discharge from hospital, with undesirable economic and environmental consequences. Because of the rising costs of healthcare, interventions to reduce medication wastage (and associated costs) are warranted. Using Patient's Own Medication during hospitalisation might decrease medication wastage and associated costs.
