Medication Adherence to Direct Oral Anticoagulants: Extent and Impact of Side Effects.

Purpose: Arterial and venous thromboembolism are a leading cause of mortality. Direct oral anticoagulants (DOACs) are highly effective in both stroke prevention and prevention of venous thrombotic events. Medication adherence is a prerequisite for optimal protection against thromboembolic complications.

[Toxidromes].

In this Clinical Lesson, using two illustrating cases, we explain how to do the initial assessment and treatment of an intoxicated patient. An approach aimed at toxidromes can serve as a stepping stone. A toxidrome is a combination of symptoms and clinical features that can occur with the use of certain drugs and substances.

External validity of an automated delirium prediction model (DEMO) and comparison to the manual VMS-questions: a retrospective cohort study.

Background: It is estimated that one-third of delirium cases in hospitals could be prevented with appropriate interventions. In Dutch hospitals a manual instrument (VMS-questions) is used to identify patients at-risk for delirium. Delirium Model (DEMO) is an automated model which could support delirium prevention more efficiently.

[Iron supplementation in iron deficiency anaemia].

Iron deficiency anaemia is a common problem. The majority of patients are treated with oral iron supplements. The current recommended dosage for oral supplementation of 200 mg ferrous fumarate 3x per day however, is based on a single small study of poor quality.

Validation of an automated delirium prediction model (DElirium MOdel (DEMO)): an observational study.

Objectives: Delirium is an underdiagnosed, severe and costly disorder, and 30%-40% of cases can be prevented. A fully automated model to predict delirium (DEMO) in older people has been developed, and the objective of this study is to validate the model in a hospital setting.

Setting: Secondary care, one hospital with two locations.

Supporting clinical rules engine in the adjustment of medication (SCREAM): protocol of a multicentre, prospective, randomised study.

Background: In the nursing home population, it is estimated that 1 in every 3 patients is polymedicated and given their considerable frailty, these patients are especially prone to adverse drug reactions. Clinical pharmacist-led medication reviews are considered successful interventions to improve medication safety in the inpatient setting. Due to the limited available evidence concerning the benefits of medication reviews performed in the nursing home setting, we propose a study aiming to demonstrate a positive effect that a clinical decision support system, as a health care intervention, may have on the target population.

The support of medication reviews in hospitalised patients using a clinical decision support system.

Objectives: First, to estimate the added value of a clinical decision support system (CDSS) in the performance of medication reviews in hospitalised elderly. Second, to identify the limitations of the current CDSS by analysing generated drug-related problems (DRPs).

Methods: Medication reviews were performed in patients admitted to the geriatric ward of the Zuyderland medical centre.

The development of an automated ward independent delirium risk prediction model.

Background A delirium is common in hospital settings resulting in increased mortality and costs. Prevention of a delirium is clearly preferred over treatment. A delirium risk prediction model can be helpful to identify patients at risk of a delirium, allowing the start of preventive treatment.

Evaluation of clinical rules in a standalone pharmacy based clinical decision support system for hospitalized and nursing home patients.

Objectives: To improve the current standalone pharmacy clinical decision support system (CDSS) by identifying and quantifying the benefits and limitations of the system.

Methods: Alerts and handling of the executed clinical rules were extracted from the CDSS from the period September 2011 to December 2011. The number of executed clinical rule alerts, number of actions on alerts, and the reason why alerts were classified as not relevant were analyzed.

Development of a computer system to support medication reviews in nursing homes.

The frail elderly populations of nursing homes frequently use drugs and suffer from considerable comorbidities. Medication reviews are intended to support evidence based prescribing and optimise therapy. However, literature is still ambiguous regarding the optimal method and the effects of medication reviews.
