Sharing the indication and intended treatment duration of multiple anticoagulant therapies with primary care
The prescription of multiple anticoagulant therapy (e.g. double or triple therapy with anticoagulants and antiplatelet agents) is complex and associated with an increased risk of bleeding. Patients often use these combinations temporarily, for example after acute coronary syndrome, percutaneous coronary intervention, or concomitant atrial fibrillation and stent implantation (1). European and Dutch guidelines therefore emphasize that double or triple therapy is never indicated for life, but always has a limited treatment period, depending on the clinical situation and the individual balance between the risk of bleeding or an ischemic event (1).
In practice, however, it appears that these drugs are regularly used for too long or are continued without a current indication, which significantly increases the risk of serious, preventable bleeding. For example, research in Dutch pharmacies showed that 14— 23% of patients who used dual anticoagulation no longer had a valid indication (2). During hospitalization, it was found that more than 40% of patients with multiple anticoagulant therapies used these combinations incorrectly (3). This risks bleeding complications, and thus unnecessary hospital admissions (4), but also contributes to unnecessary costs and environmental impact.
To prevent this, clear communication during dismissal and transfer is crucial. Explicitly sharing the indication and the intended treatment duration with primary care (general practitioner and pharmacist) enables follow-up care providers to continue treatment responsibly or to stop it in time. This contributes to medication safety, reduces the risk of complications and prevents unnecessary drug use.
Intervention
Preventing unnecessarily long use of multiple anticoagulant therapies by sharing the indication and intended treatment duration with primary care providers.
Environmental impact
This intervention primarily focuses on improving communication about the indication and intended treatment duration of multiple anticoagulation. A possible link to environmental impact will follow.
Working method
1. Determine population and formulate goals
- Determine the department (s) and/or patient group (s) that this intervention will focus on.
- Focus on departments and/or indications where multiple anticoagulant therapies are indicated, such as neurology, cardiology and vascular surgery.
- Evaluate how often indication and treatment duration are currently recorded and shared in letters of discharge and medication transfer using prescription data and letters of discharge in the EPD, see “How to evaluate a drug intervention”.
- Formulate SMART goals together with (the green team of) the relevant department (s). For example: Within six months, ≥ 90% of discharge prescriptions for multiple anticoagulation include both an indication and an intended treatment duration.
2. Implementation
- Establish a standard method for prescribing multiple anticoagulation, which always explicitly states the indication and intended treatment duration, see “How to ensure the transfer of information between hospital and primary care”.
- Make this mandatory in the EPD, for example via mandatory fields in order sets or prescribing modules.
- Make sure that letters of resignation and medication transfers to the front line automatically include the indication and treatment duration.
- Make process agreements about exceptions, for example patients whose treatment time depends on later evaluation.
- Inform the prescribers and pharmacists of the department concerned and, if necessary, the Medicines Committee about the change, for example by briefly explaining the change during transfers and/or team meetings.
3. Monitoring and Evaluation
- Monitor implementation using (outpatient) clinical prescriptions and discharge prescriptions, see “Method of evaluating a drug intervention”. Discuss (interim) results regularly, for example (twice) monthly, during transfers, team meetings and/or teaching.
- Reflect on results in relation to the set goal, obstructing and promoting factors. Adjust interventions if necessary.
- At the end of the follow-up period, evaluate whether the goal (s) is/have been achieved and how the change is secured.
- Provide (interim) results back to the implementation supervisor.
How is this measured?
This intervention focuses on improving communication about the indication and intended treatment duration of multiple anticoagulation, which can be measured by the proportion of discharge prescriptions and letters stating the indication and intended treatment duration.
When successfully implemented?
Based on the increase in the proportion of prescriptions with indications and intended treatment duration, as described in the previous section, determine when the implementation is considered successful, and reflect on the set goal.

Targeted prescribing of proton pump inhibitors (as stomach protection)
Proton pump inhibitors (PPIs) are antacids that are frequently used. Pantoprazole (1.3 million users) and (es) omeprazole (1.2 million users) were among the top 3 most used medicines in 2023 (1). However, it appears that a large number of these drug users have no indication for PPI use (anymore) (2). With short-term use, more than half of the patients appeared to have no indication (3). Part of this is caused by starting PPIs as stomach protection without indication.
The NHG guideline “Prevention of stomach complications due to drug use (NL)” and the knowledge document proton pump inhibitors (NL) indicate that a PPI is indicated as stomach protection based on risk factors, such as age, ulcer or history of stomach complications, NSAID dosing, co-medication with an increased risk of stomach complications and comorbidities, such as rheumatoid arthritis, heart failure or diabetes (4 - 6). By prescribing PPIs based on risk factors for stomach protection, unnecessary PPI use can be reduced, thereby preventing environmental impact.
Clinical care
Paracetamol should be administered orally instead of intravenously
To treat postoperative pain, intravenous (IV) acetaminophen is usually administered. However, research shows that oral (PO) administration is equally effective and more sustainable in most patients. A systematic review of 14 studies shows that there is no convincing difference in the analgesic effect between IV and oral acetaminophen at different times after surgery (1). However, the environmental impact varies considerably: CO2 emissions from IV administration are up to 16x higher (2). Where an oral administration of 1 gram of acetaminophen from a blister results in the emission of approximately 38 grams of CO₂ eq., this can be up to 628 grams when administered IV, depending on the packaging and administration material (2).
In most patients, acetaminophen can be administered orally, as described in the NVZA Monograph 'Paracetamol' (3). The paracetamol challenge demonstrated that IV acetaminophen administration can be reduced by at least 25%, saving staff time, costs and environmental impact (4). These results underline deployment at a larger scale.

Restrictive opioid prescribing with indication and intended treatment duration
The most commonly used, high-acting opioids are morphine, fentanyl, oxycodone, and buprenorphine (1). In 2024, more than 1.1 million people received an opioid through the public pharmacy (2). Although the total number of benefits in kind fell slightly compared to 2023, the number of prescriptions from the hospital actually increased slightly (3). A first dose of a high-acting opioid included an average of 9 days of medication in 2024 (3), while acute pain due to trauma or surgery often requires only 48 hours of strong opioid pain relief (4). Prescribing opioids for too long increases the risk of dependence and also leads to unnecessary environmental impact.
Research shows that the amount of opioids that patients receive at discharge influences their actual use (5). As recovery progresses, the need for opioids decreases rapidly; four days are sufficient for most patients. This is in line with international recommendations that recommend a duration of 3 - 7 days (6-8). The guideline of the Dutch Association of Anesthesiology (NVA) also recommends appropriate use of opioids through restrictive prescribing (up to 7 days) tailored to the pain experienced (9).
Another bottleneck is that the intended treatment duration and indication of opioids at discharge or outpatient dispensing are not always explicitly stated or shared with patients and primary care providers. As a result, GPs and pharmacists often lack crucial information to continue treatment responsibly or to phase it out in time. This increases the risk of unnecessarily long use, and thus unnecessary environmental impact and risk of dependency.

Treatment with oral antibiotics when bioavailability is good
Based on a recent opinion article This intervention has been selected in the NTvG by Kaal et al. This article recommends that there is more room for oral antibiotic initiation, but does not describe clinically tested interventions. This intervention will therefore be further developed on the basis of available scientific literature and will follow at a later date.
