Why was it done?

Exchanging medication stocks between hospital wards is a common method for reducing pharmaceutical waste at hospitals. However, the impact of such systems is unclear. Therefore, we aimed to calculate the annual economic cost savings after the establishment of a medication exchange system at the University Hospital of Southern Denmark in Aabenraa.

What was done?

A medication exchange system at a Danish hospital was evaluated according to avoidance of medication waste and potential economic impact.

How was it done?

For two weeks in February 2024, pharmaconomists registered all medications that were exchanged between six hospital wards representing 147 of 302 hospital beds. The quantity of the excess medications when returned was registered and the amount of pharmaceutical waste was calculated. This was compared to the amount of waste incurred by ordering a whole package for the ward. Moreover, the economic cost was calculated based on the value per package and compared to the economic costs of purchasing whole packages.

What has been achieved?

In total, 244 exchanges were registered. The pharmaceutical waste was estimated to 13-26%. The Department of Pulmonary Diseases, followed by the Department of Gastrointestinal Diseases, caused the greatest waste. The exchanged medicine had an economic cost of 3,566 DKK (478 euro). In comparison, the cost of purchasing whole packages was estimated to 21,042 DKK (2,822 euro). Thus, the total cost saving was ((21,042-3,566 DKK)x(52/2 weeks)=454,376 DKK (60,935 euro), corresponding to ((454,376/147) x 302)= 933,480 DKK (125,146 euro) for the entire hospital. The results led to establishment of a physical medication room to store the excess medication available for other clinical wards. All medications are registered electronically to support optimal use of excess medication throughout the hospital.

What next?

The economic evaluation may be replicated for comparable medication exchange systems at other hospitals, and thus, generate evidence for the economic and environmental impact of the system.

Why was it done?

A significant proportion of valuable medications, often produced far from where they are used, ends up discarded without ever being administered. Due to limited visibility into actual medication use, hospitals face challenges in understanding which drugs contribute to waste.
Analyzing internal data allowed us to gain insight into different aspects of medication waste. Addressing these aspects successfully improved sustainable use of medication.

What was done?

We developed a medication waste dashboard to promote sustainable decision-making across medication policies, purchasing, prescribing, distribution, administration, and waste management.

How was it done?

Daily, hospital pharmacies register all medication orders and dispensations (to patients or for stock), while nursing staff document actual administrations. The discrepancy between dispensed and administered drugs provides useful insight into unnecessary medication waste.

What has been achieved?

We integrated dispensing and administration data into a dashboard, offering real-time visibility at the organizational, departmental, ward, and drug group levels. This tool allows our multidisciplinary team to conduct trend analyses and implement greener practices. Key outcomes include: 1) reduction of medication waste, 2) preventing excessive stock accumulation, 3) optimizing internal processes, and 4) maximizing reuse. Additionally, these data supports effective management during drug shortages and provides critical insights into missing opioids.

What next?

Utilizing data allows us to retrospectively analyze trends and project future scenarios, unlike traditional waste-bin audits. This data-driven approach empowers us to make proactive adjustments, guiding hospitals toward long-term medication waste reduction and facilitating benchmarking across healthcare institutions.

Why was it done?

In 2021, over 110,000 kilograms of pharmaceutical waste was produced at HUS Helsinki University Hospital, Finland (HUS). That was almost 2.5 million euros when the value of the medicines and the pharmaceutical waste management costs were considered. In 2022, HUS Pharmacy launched a project to reduce pharmaceutical waste, both for economic and environmental reasons.

What was done?

The goal was to reduce the annual pharmaceutical waste in euros and in kilograms at HUS, primarily at the Pharmacy. We also aimed to help departments to reduce their pharmaceutical waste.

How was it done?

The project group was formed of about 15 pharmacists and pharmacy technicians from different units of HUS Pharmacy, located in different areas in Southern Finland. The project team met monthly to review the costs and causes of pharmaceutical waste at the Pharmacy. The team discussed challenges, shared good practices and came up with ideas. In addition, departments were supported in reducing pharmaceutical waste with lectures, materials, videos etc.

During the project we found three main reasons for producing pharmaceutical waste: expired products, residues of cytotoxic drugs and compounding errors. To avoid these, we created a better overview on the whole stock of the Pharmacy, internal communication was increased, and products were moved more actively between units. Unit-specific procedures were also developed, collaboration with departments was increased, and published studies were used especially to reduce cytotoxic waste.

What has been achieved?

During the project, the annual value of wasted pharmaceuticals at the Pharmacy decreased from 928,000 euros (year 2021) to 507,000 euros (year 2023). In addition, the annual amount of pharmaceutical waste at HUS reduced from 112 000 kilograms to 101 000 kilograms. Also, the total cost of pharmaceutical waste at HUS, including the value of wasted pharmaceuticals, decreased.

What next?

The project team’s work has become a permanent part of our work instead of a project.
Collaboration between all healthcare workers is in a key role for reducing pharmaceutical waste. Waste cannot be completely avoided, but it can be reduced significantly, as our project has revealed.
Procedures must be developed further, for example early notifications from departments to the Pharmacy about changes in medical practices are critical for managing our stock.

Why was it done?

Medical devices (MDs) and drugs account for 55% of the carbon footprint of a hospital’s French healthcare system, making this sector a key focus for the ecological transition. The MD sector alone is responsible for 32% of our hospital’s CO2 emissions, underlining the need to rethink our practices in order to reduce our environmental impact.

What was done?

Elimination of waste produced unnecessarily by optimising customised packs (CP) containing the MD required for treatment.

How was it done?

After a multidisciplinary team (pharmacists, intensive care units, anaesthetists, nurses) was put together, packs containing unused medical devices (UMD) were identified in 2 pilot departments: anaesthesia and intensive care. The packs were weighed with and without the UMD. The savings in terms of waste weight and carbon footprint were calculated according to the type of waste: general waste or biohazardous waste. In conjunction with the medical teams and suppliers, the re-evaluation of the MD required and the withdrawal of UMDs led to the updating of CP in the pilot departments.

What has been achieved?

The packs identified include: the suture pack (SP), the central venous line pack (CVL) and the epidural pack (EP). Over one year, the weight of waste avoided was: 64 kg for the SP, 87 kg for the CVL pack, 55 kg for the EP. After modifying these packs, annual CO2 emissions were reduced by 55% for the SP, 14% for the CVL pack and 8% for the EP, with a total annual saving of €5,423. The annual weight of waste was reduced by 206 kg, a saving of 92 kg of CO2: the equivalent of 86 Paris-London train journeys.

What next?

The re-evaluation of CP can generate a significant ecological impact. This initiative is intended to be rolled out on an institutional scale, with the active collaboration of the sustainable development department, and as part of future calls for tender. These adjustments save time for care staff, significantly reduce the carbon footprint, and contribute to the ecological transition. It is essential to strike a balance between economic and environmental imperatives, given the financial constraints facing public hospitals.

Why was it done?

Hospital Pharmacies and especially the laboratories produce wastewater containing medicine residue. When this wastewater is discharged into sewage it contributes to the load of pharmaceutical residue and ultimately to pollution of surface-, ground and drinking water. To reduce this load, waste can be collected and transported to a processing facility for incineration and deactivation or alternatively treated locally. Our goal was to develop a practically applicable method that could effectively reduce the pharmaceutical sewage load locally, at the source.

What was done?

We developed a practical, compact, disposable filtration system that can be used on-site to reduce the amount of pharmaceutical residue in wastewater of our pharmaceutical laboratory. We tested and optimized the composition of the filter to effectively collect organic substances from locally produced wastewater (influent). We monitored filter performance and durability by analysis of filtrates (effluent).

How was it done?

Laboratory wastewater was collected during one month to yield 10 L influent. Portions of influent were filtered through 9 different types of filter packing and the effluents collected for analysis.
The influent reference and effluent samples were analysed using an iontrap LC/MS screening method using diazepam-D5 as an internal standard. The signal abundance 12 most relevant substances was chosen to evaluate the level of reduction by filtration. Based on these analyses, the optimal filter packing was determined.

What has been achieved?

In the effluent of the best performing filter packing, the abundance of 9 substances was reduced by 91,5-99,9%. The abundance for the other 3 substances was below detection limit.
Substances removed more >99%: atorvastatine, carbamazepine, clarithromycine, diclofenac, granisetron, midazolam, naproxen, propranolol and rocuronium. Substances removed between 91-99%: cefazolin, ephedrine and ropivacaine.

What next?

The optimal filter composition will be tested in practice in a test setup. In addition, cost effectiveness and sustainability compared to alternative waste collection methods will be evaluated.

Why was it done?

We decided to experiment this new solution on coronarography-packs, which presents the biggest rotation among surgery-packs (5,392 units estimated for 2,023), in order to improve working conditions of logistic workers, decrease musculoskeletal disorders (MSD) and optimise storage.

What was done?

Pallet box have been implemented as a new logistic solution for surgery-packs in our hospital pharmacy on a proposal from one of our biggest suppliers. The aim of this comparative study between 52-pack pallet boxes and the previous storage solution by 4-pack boxes was to assess the potential benefit on handling work, storage, waste and its economic impact.

How was it done?

In order to compare these two solutions, we clocked the time and evaluated the cost of transport from delivery gate to storage room and healthcare-unit order-picking step (from picking up the first pack to cardboard flattening). We also estimated the amount of waste associated.

What has been achieved?

Pallet-boxes enable a 24% room saving (52 pallet-spots yearly (2 pallet-boxes piled on one spot) instead of 68) and a 31% global time saving (22 hours yearly (13h transport + 9h order picking) instead of 32 hours (17h transport + 15h order picking)). Time saving on order picking was 40%: picking step of one pack from a pallet box requires on average 6 seconds whereas 10 seconds were needed from 4-packs-boxes. Yearly 104 pallet-boxes (603 kg of empty cardboards) will be manipulated whereas 1,348 4-pack-boxes (1,213 kg) used to be handled resulting in a 2-fold decrease. Even though pallet-boxes halve cardboard-waste, they represent 1.5 times more wooden-pallets’ waste (104 versus 68). Furthermore the price of coronarography-packs are impacted by a 2% increase representing around 4,100€ yearly which is not balanced by savings on transport or order picking (10h ≈ 150€).

What next?

Logistic workers are unanimously satisfied in implementing pallet-boxes as it facilitates their work on many aspects: pallet transport, order picking, waste disposal. Despite being costlier, a decision has been made to implement pallet-boxes in the long-term in order to improve waste management and working conditions of logistic workers. Our hospital pharmacy is already thinking about extending pallet-boxes to other references in order to assess more precisely their impact on MSD in logistic workers.

Why was it done?

Healthcare is responsible for an important part of the carbon footprint and medication production and use contribute substantially to this footprint. In line with Green Teams being established in all layers of society at the moment, the UMCG departments were also starting to implement such teams. The CPP was among the first departments establishing such a Green Team in order to reduce the footprint of medication use.

What was done?

The department of Clinical Pharmacy and Pharmacology (CPP) is responsible for providing pharmaceutical patient care to all hospitalised and ambulatory patients of the University Medical Centre Groningen (UMCG) in tThe Netherlands. Two years ago, the department has established a Green Team, dedicated to making this pharmaceutical care as sustainable as possible.

How was it done?

The Green Team CPP started in June 2021 with a brainstorm on potential subjects. As the main focus we chose to ‘contribute to sustainable medication use and to reduce disposal’. The team consists of representatives of all CPP sub-departments. Proactive measures and projects were defined, but increasingly the Green Team is being consulted by doctors and nurses regarding issues on sustainable medication use. Department-wide awareness is fuelled by a periodic newsletter.

What has been achieved?

Three projects were conducted: 1) Switching from paracetamol intravenous therapy to oral/rectal therapy (based on doctor’s question); 2) Patient’s own medicine use combined with self-administration of medication (POM/SAM project; based on nurse question); 3) Exploring oral anticancer drug waste by patient interviews (in preparation of improvement measures; proactive Green Team project). The results of these projects are of interest to all European hospital pharmacists and can inspire others to establish Green Teams to contribute to sustainable pharmaceutical care.

What next?

Given the success of the paracetamol project, we will expand this to other intravenous medications. The pilot project on POM/SAM has inspired us to implement POM/SAM within all nursing departments of the UMCG. And the results of the interviews on oral anticancer waste form a solid justification of the necessity of implementation of re-use of medication. In addition, we will continue to perform new proactive projects, aimed at deprescribing (by performing medication reviews), improving medication adherence, optimising the logistics of medication (reducing the amount of medication being dispensed, implementing of ready to administer medication, implementing of pharmacy IV service), reducing medication and financial waste using vial rounding, and proper disposal of medication. We will also continue to be the expert group to which doctors and nurses can direct their questions on sustainable medication use.

Why was it done?

Clinical Pharmacy pharmaconomists perform a wide range of tasks at the hospital for example, medicine service with medication ordering, placement and checking of expiry dates. A sustainability project in 2020 highlighted manual and time consuming workflows, for example, manual reading, interpretation and notation of expiry dates in paper forms, when medicine rooms are reviewed for medicine that expires within the next half year. The dream of an easily accessible digital solution arose to make workflows more flexible, modern and sustainable.

What was done?

A smartphone application for managing expiry dates in medicine rooms and reduction of medicine wastage was applied.
With the application, the smartphone camera can be used to scan the data-matrix of medicine packages and get a sorted overview of medicine and its expiry dates. In the application you can register a medicine package as either used, discarded or released. By releasing medicine packages, the medicine is made available to colleagues in other medicine rooms at the hospital.

How was it done?

A smartphone application was developed in close and synergistic collaboration between software engineers, pharmaconomists and pharmacists. The smartphone application was initially tested in small scale, and then adjusted and implemented among pharmaconomists and pharmacists to be used in up to 129 medicine rooms at the hospital from January 2022.

What has been achieved?

The application creates value for the Hospital Pharmacy, the Hospital and the society because:
– It takes significantly less time to check and scan expiry dates
– We avoid misinterpretation of expiry dates; and
– By releasing medicines to be used in other medicine rooms, the application makes it easier for us to work sustainably. In nine months, 1700 packages with a total cost of
€121.000 has been moved between medicine rooms in an attempt to avoid medicine wastage.
At the hospital we have a mutual medicine budget. Therefore, it makes good sense to move medicine between medicine rooms to get the most health for the money.

What next?

Implementation of the smartphone application among pharmaconomists in other hospitals within the same region is considered. Also other hospital pharmacies in the country have shown their interest. In addition, a similar application for utensils is under development.
