Targeted prescribing of proton pump inhibitors (as stomach protection)

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.

Antiemetics, such as 5HT3 antagonists (e.g. ondansetron and granisetron) and dopamine antagonists (e.g. metoclopramide), are widely used in clinical care to prevent and treat nausea and vomiting, for example postoperatively or during chemotherapy. Research shows that antiemetics administered enterally (e.g., orally or rectally) at an equivalent dose usually have a similar effectiveness and safety to those administered intravenously (IV) (1-2).

The oral/rectal route contributes to greater comfort and autonomy. In addition, the use of oral/rectal medication is more cost-effective and sustainable, because fewer disposable materials are required than intravenous administration (3). In situations where oral administration is not feasible, such as severe nausea or vomiting, rectal administration may sometimes still be chosen. IV administration is only eligible if this is not possible. This is further detailed in the NVZA monographs (4-6).

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.

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.
