Why was it done?

Sequential therapy, or switch therapy, consists of an early conversion from intravenous to oral (PO) treatment, without compromising the therapeutic effectiveness. In advantage, PO in selected cases, avoids intravenous associated risks, it is more comfortable to patients and represents an important economic saving.

The aim of the GPI was to implement a daily program that allows the pharmacist to identify the patients that would benefit from the AST.

What was done?

Implementation of a program of antibiotic sequential therapy (AST) and evaluate the outcome of the pharmaceutical recommendations carried out in a third-level hospital.

How was it done?

A database was created to select the active antibiotic prescriptions with more than 72 hours duration, susceptible to AST: metronidazole, clindamycin, levofloxacin, ciprofloxacin and linezolid.

Patients clinical criteria for initiating AST were established as:
• Temperature ≤ 37 ºC
• Systolic blood pressure ≥ 90 mmHg
• Heart rate < 100 bpm • Respiratory rate < 24 rpm • Oxygen saturation ≥ 90% • Capacity for oral intake Once the patients were identified, the pharmacist communicated the recommendation to the doctor in charge, and worked together to make a final decision. Due to the high burden of care, the follow-up of patients who could not be substituted to PO in the first 72 hours was lost.

What has been achieved?

From October 2022 to March 2023, 453 patients on intravenous antibiotic treatment were reviewed. The mean age was 65.7 ± 20.9, and 57.4% of the patients were men.
47 patients were selected as they met the established criteria.

All the antibiotics presented a similar percentage of recommendation with a mean of 19.2% ± 6.3. Of this percentage, 59.6% of the patients were switched to oral antibiotics. Stands out linezolid, with a 83.3% of acceptance.

Lower respiratory tract infections were the most prevalent, representing 51.6% of the total. However, only 11 patients (5.1%) were suggested for AST due to the frequent use of nasal spectacles or oxygen therapy, a criterion that excludes AST

What next?

The high number of accepted recommendations shows the importance of implementing an AST programme in order to optimize antimicrobial treatment, and this initiative could be easily implemented to all Pharmacy Services.

Shared decision-making between pharmacists and physicians is key to PTC functioning and efficiency. Responsibilities include managing policies and procedures for appropriate use of high quality and cost-effective health technologies at hospitals. PTC performance is paramount to overall hospital efficiency.

What was done?

This project seeks to assess and redesign (optimize) existing Pharmacy and Therapeutics Committees (PTC) procedures within a University Hospital Centre (UHC – six public hospitals). The goal is to enable sound decision-making that significantly contributes to UHC key performance indicators, all while ensuring timely patient access to effective medication.

How was it done?

The project comprises four phases: (1) gathering feedback from stakeholders (PTC members; hospital service/pharmaceutical department directors) regarding their current involvement in PTC information flows, procedures, and decision-making; (2) developing a value-based criteria-matrix, across stakeholders, in a multiple-criteria decision analysis context, to guide future PTC decision-making; (3) rethinking PTC procedures and information flows; (4) assessing the effectiveness of the redesigned PTC model after 12 months. First phase included: a Likert-scale based survey1 for PTC members to evaluate their involvement in activities described in the internal PTC regulation, and a semi-structured interview-based survey2 for all stakeholders to characterize existing information flows and PTC mediated decision-making processes.

What has been achieved?

First phase: eight of 10 PTC members participated in survey1. Activities with 100% engagement of PTC members: prescription reviews; coordination with National PTC; monitoring of medicine utilization, antibiotics resistance and safety; advise the UHC management board. Activities with major non-engagement: monitoring/reporting of complementary diagnostics prescription (87.5%); medication therapy management programs (62.5%); National pharmacovigilance system activities (62.5%); therapy cost assessment (50%). In survey2 (n=14) authorization process for medicines utilization was accurately characterized, clearly identifying responsibilities for all clinical and pharmaceutical departments. Heterogeneity exists between urgent and non-urgent utilization requests. PTC members and pharmacy departments were more likely to use electronic platforms than clinical departments.

What next?

Next phases are under way to better support current competencies, information flows, procedures, and the shared decision-making processes offering an opportunity to rethink the PTC procedures in the University Hospital Centre and leverage efficiency over hospital complexity.

Why was it done?

Chronic Obstructive Pulmonary Disease (COPD) and asthma represent a significant public health issue. Medications are administered using inhaler devices (ID) that require prior demonstration to ensure their proper use. Incorrect usage of inhaler devices might have a major influence on the clinical effectiveness of the delivered drug.

What was done?

The goal of our study was to detect potential errors in the manipulation of inhaler devices (ID) and to provide patients with appropriate information on their correct use in order to improve medication management.

How was it done?

For this study, every hospitalised adult patient with an ongoing treatment with ID underwent a pharmaceutical interview during their hospitalisation.
This interview was done using a questionnaire assessing the patient’s knowledge of their medications and a 12-items evaluation grid covering every step of proper inhalation technique.

What has been achieved?

Between June and August 2023, 27 patients were interviewed: the average age was 73 years. 34 ID manipulations were observed. Dry powder inhalers were the most prescribed DIs (68%), followed by pressurized metered dose inhalers (23%) and soft mist inhaler (9%). For 10 DIs (29%), no explanation was given to the patient. Furthermore, inhaler technique instructions were provided by a pulmonologist (65%), general practitioner (23%), pharmacist (4%), nurse (4%) and therapeutic education program (4%). The interviews revealed that 71% of patients were not familiar with the prescribed molecules or their mechanism of action. Out of the 34 DI manipulations, only 15% were performed perfectly, and 27% were not executed properly. The steps of deep exhalation before inhalation and breath-holding after inhalation were not performed in 70% and 62% of observations, respectively. Finally, 50% of patients did not rinse their mouths after using inhaled corticosteroids.

What next?

This study has highlighted the improper use of DIs, which can lead to a loss of therapeutic effectiveness. Therefore, we have developed 9 information booklets on the correct use of the DIs that describe different handling procedures for proper inhalation. These booklets are provided at the end of the interview. Educating patients on the proper use of these inhalation devices during the initial prescription or dispensing should lead to an overall improvement in patient care.

Why was it done?

The motivation behind NoHarm stemmed from the time-consuming nature of the prescription review process, which required clinical pharmacists to assess not only drug interactions but also factors such as appropriateness, effectiveness, safety, adherence, and affordability of drug therapies. NoHarm was envisioned as a solution to systematize the workflow and provide cross-referencing of essential drug and inpatient information, thereby addressing these issues.

What was done?

The NoHarm initiative was developed to address challenges faced by clinical pharmacy teams during the prescription review process in a hospital setting. This open-source intelligent system was introduced to enhance the medication review process. The initiative was executed in a 420-bed public hospital in Brazil over a 17-month period to evaluate its impact on prescription reviews.

How was it done?

The implementation of NoHarm involved integrating the system with the hospital’s electronic health records to collect and compute all inpatient data. NoHarm utilized a drug knowledge base and intelligent algorithms to identify and alert healthcare professionals about inpatient risks. The algorithms were designed to cross-reference patient laboratory results with drug thresholds, adjust for liver and renal function, analyze drug usage patterns at the hospital, and extract patient risk factors from clinical notes, including diseases, adverse events, symptoms, and biometric data.

What has been achieved?

The number of medications assessed increased dramatically from 17,000 to 2,643,957 within the 17-month period, all while maintaining the same team size. Improved prescription review rates, rising from 65% to 94%, demonstrate the effectiveness of the system. Furthermore, these improvements in prescription reviews resulted in better clinical pharmacy services and contributed to reducing medication errors and associated risks in patient care at the hospital.

What next?

NoHarm is an open-source solution and an example of good practice in healthcare due to its achievements in streamlining prescription reviews and enhancing patient safety. Its successful implementation led to increased efficiency, higher prescription review rates, and substantial cost savings, showing its potential as a model for other healthcare settings. Its prospective global applicability makes it a solution to address medication errors and elevate the standard of care in healthcare institutions worldwide.

Why was it done?

We unveiled during an audit that, in the past 2 years, 19% of our hospital DAOCs prescriptions were underdosed: due to the population profile (old, frail), the conventional bleeding risk scores were consistently high and, as such, not informative. To avoid a hypothetical bleeding risk, physicians were randomly underdosing patients beyond guidelines, without any evidence regarding the efficacy.

What was done?

Using machine learning, we unveiled that underdosing direct oral anticoagulants [DAOCs] to prevent bleeding risk in an old and frail population had no significant impact on drug-related hospitalization [DRH] nor death, and cannot be supported. To help targeting patients for whom extra care would be more beneficial rather than underdosed DAOCs, we built a predictive model of bleeding events and provided risk factors among our population.

How was it done?

We performed a retrospective study, based on data collected during the audit, of patients treated between October 2020 and April 2022 with Apixaban or Rivaroxaban for atrial fibrillation [AF]. Demographic and clinical criterias (i.e., GFR, polypathology, co-medications, prescribed DAOC, respecting dosage and scheduling) were collected. The occurrence of specific outcomes (i.e., bleeding and thrombosis that led to medical care and drug seizure, DRH and death) were retrieved from the patients’ medical records. Machine learning explorations were performed using RStudio®.

What has been achieved?

119 patients were included. We modeled using logistic regression the impact on selected outcomes of underdosing DAOCs. We found out that underdosed DAOCs were associated with a lower bleeding risk (OR=0.30, CI95%[0.07;0.95]), a higher thrombosis risk (OR=6.67, CI95%[1.23;50.0]), but without any impact on DRH nor death. Unsupervised algorithms unveiled that DAOC choice (Rivaroxaban: OR=2.80, CI95%[1.15;7.13]), sex (Male: OR=0.44, IC95%[0.16;1.12]) and using dosages from guidelines (OR=3.32, CI95% [1.05;14.80]) were predominant explanatory variables regarding bleeding risk. The choice of DAOC was the only covariate that impacted DRH (Rivaroxaban: OR=2.78, CI95%[1.22;6.56]). Finally, using a gradient-boosting algorithm, bleeding risk was predicted with a 0.73 roc-auc, superior to conventional models.

What next?

Therapeutic education of patients and caregivers, telephone follow-up or pharmaceutical consultations will be implanted for patients at high bleeding risk. An audit will be performed next year to measure underdosed prescriptions rate, and improve the model with new data.

Why was it done?

The demand and use of immunoglobulins (IgGs) is growing, and there are many difficulties in obtaining supplies. This situation has been worsened during and especially after COVID-19 pandemic. A low number of blood donations and apheresis procedures, caused a shortage of IgGs worldwide. The measures implemented (dose and period optimisation) ensured the achievement of an adequate balance between supply and demand, enabling an increase of plasma fractionation industry.

What was done?

A rationalisation plan of human IgGs use was implemented in a tertiary hospital through the multidisciplinary groups, in which Pharmacy Department (PD) participated.

How was it done?

Inside hospital working groups were created between the different IgGs prescribing departments (paediatrics, haematology, immunology and neurology) and PD during a period between 1 May 2021 and 31 October 2021. All patients on regular treatment with IgGs were identified and each one was reviewed: indication, dose, regimen and treatment alternatives. Based on the document “Criteria for the rational use of human immunoglobulins” published by the Madrid Health Service in 2021 and taking into account the clinical circumstances of each patient, decisions were made regarding: continuation or discontinuation of treatment and dose or regimen adjustments.

What has been achieved?

After identifying 184 patients treated with IgGs, a set of pharmaceutical policies has been drawn up in conjunction with stakeholders. Evidence-based intervention focused on assessing the clinical adequacy of actual treatments, optimising indications and dosing, to ensure an equitable supply was done. A total of 34 patients (%) discontinued IgGs, 24 patients reduced doses and 15 increased time between administrations.
As a result, it has been possible to continue the treatment in those patients for whom its use was a vital urgency during shortage period.

What next?

Long-term follow-up is necessary to better analyse the impact of the established measures. Registries play an important role in collection of systematic data to analyse, synthetise, and obtain valuable information for decision support. five patients had to restart IgGs treatment and seven patients had to come back to the initial regimen. Even so, politic rationalisation in special situations is a key factor of pharmaceutical activity to ensure treatments for patients who need it the most.

Why was it done?

For discharge medication to be dispensed a medicines list plus discharge letter, often referred to as a To-Take-Out (TTO) is required. The letter section communicates information for safe patient transfer and provides context for the pharmacist clinical verification. With increasing demands on junior doctors, the production of TTOs is often delayed until after all urgent clinical duties are completed, so dispensing commences late in the working day. in addition, junior doctors’ prescribing errors cause delay while queries are resolved. The late completion of TTOs slows patient flow across the whole system. It was accepted that a different strategy, using a PP to prioritise prescribing, needed exploration.

What was done?

A prescribing pharmacist (PP) was embedded within a specialist medical team, to perform prescribing activities in a timely manner, with a focus on discharge prescriptions. The PP was additional to the standard ward pharmacy establishment, allowing prescribing to be the focus of the role.

How was it done?

A PP was embedded within the Respiratory team and another within Gastroenterology with the primary aim of producing TTOs as early as possible. There was a requirement for the PP to learn how to write the discharge letter, via training with junior doctors. The PP prioritised any prescribing to facilitate discharge, but also attended the consultant ward round undertaking medicines optimisation for each patient. Rather than the junior doctor returning later to prescribe, the PP made any necessary medication changes during the ward round, facilitating the timely receipt of appropriate therapy.

What has been achieved?

Both pilots reduced the time from medically fit for discharge to the TTO written by approximately 3 hours. There was a reduction in prescribing error rate of 37% to 1% in Respiratory and 9.5% to 0.7% in the Gastroenterology project.

What next?

The “Embedded Prescribing Pharmacist” role is now permanent within the two pilot specialities, with plans for further extension under consideration. The role demonstrates the “Right first time” concept and a modernised model of hospital pharmacist practice.

Pharmacogenomics has a large potential to optimize individual patients’ both current and future drug therapies. In Belgian hospitals however, pharmacogenomics is still rarely used in clinical practice posing great opportunities for hospital pharmacies to explore this field and setting up new services.

What was done?

The Centre for Medical Genetics (CMG) of UZ Brussel, a 721-bed tertiary hospital in Brussels (Belgium), has been performing next-generation sequencing of mendeliomes for diagnostic purposes since 2016. Pharmacogenomic data is thus potentially available, but currently not further used. As hospital pharmacists, we wanted to explore the possibility of reporting pharmacogenomic information as ‘secondary findings’, in particular prevalence of actionable pharmacogenes and gene-drug interactions (GDIs) in our own population, and to determine required features and opportunities of a future pharmacogenomics project

How was it done?

Firstly, 14 pharmacogenes comprising 626 loci were selected based on available guidelines, clinical relevance and whether the gene was included in the mendeliome gene set. With the support of CMG, we then reviewed available data for patients with a mendeliome analysis between 01/03/2016 and 30/06/2020. To enable haplotype assignment, a Python script was developed displaying possible haplotypes with corresponding ‘matching score’ and ‘completeness score’. Where possible, phasing was done using pedigree information. Resulting phenotypes were finally further linked with medication histories, abstracted from patients’ electronic medical records in order to identify possible GDIs.

What has been achieved?

Pharmacogenomic data could be re-used for 536 individual patients, revealing that at least 76.9% had one or more actionable phenotype while 60 GDIs with varying relevance were found. CYP2C9 had the most actionable phenotypes (174/536) and was involved in 42 GDIs. However, not all phenotypes (e.g. copy-number variants) were detectable for CYP2C19 and CYP2D6 due to limitations of current mendeliome data and used platform.

What next?

Reusing genomic data has great potential and can be an ideal stepping-stone towards developing and implementing pharmacogenomics in other hospital pharmacies but requires a good interplay between pharmacists, geneticists and bio-informaticians. In our hospital this initiative has led to in-depth collaboration between pharmacy and medical genetics department focusing on validation and implementation of a pharmacogenomics-array coupled with implementation of a pharmacogenomics service, next to pharmacological use of whole-genome sequencing data.

Why was it done?

-lactams have proven to be effective and safe antibiotics over their history, and as a consequence, these drugs are typically among the most frequently prescribed in hospital settings. Optimization of treatment with β-lactams can be achieved by their administration by continuous infusion. Furthermore, this approach leads to a reduction of the nursing time devoted to preparation and administration. However, information regarding continuous infusion of β-lactams is not readily available for most antibiotics, leading to doubts about dosing, renal adjustments and administration, particularly uncertainties related to dilution of the antibiotics as most patients benefit from fluid restriction. Also, it was indispensable to understand which antibiotics had stability to be administered through continuous infusion.

What was done?

A protocol for continuous infusion of β-lactams was established in a coronary care unit (CCU), replacing the previous method of intermittent dosing in most patients.

How was it done?

Firstly, we evaluated which antibiotics benefited from this approach and had, simultaneously, stability. The antibiotics selected were Cefotaxime, Ceftazidime, Cefepime, Cefuroxime, Piperacillin/tazobactam, Penicillin G, Ampicillin and Flucloxacillin. In order to stablish a protocol for continuous infusion of these antibiotics, an extensive literature review was performed. Information about loading and maintenance dose, reconstitution, dilution (solvent and maximum concentration), infusion rate, renal adjustments, stability and storage was collected and summarized in a table.

What has been achieved?

A ready-to-use version of the β-lactams continuous infusion protocol was developed. In addition, dosing adjustments in patients on continuous renal replacement therapy, commonly made in patients in the CCU, were included too. This protocol was made available to all health professionals through the hospital’s intranet as well as posted in the CCU in order to be easily accessible by doctors and nurses. Thus, continuous infusion is now the standard for most patients requiring therapy with β-lactams in the CCU.

What next?

The implementation of this protocol has an education purpose, allowing the best use of documented practices in prescribing, medication review and administration continuous infusion of β-lactams. This protocol can similarly be easily implemented in other medical units. In the near future, we plan to monitor the compliance to the protocol and consider further improvements if necessary.

Why was it done?

Prior to the start of the project, inpatient treatments were not validated. The objective of this pharmaceutical care project was to improve the pharmacotherapy of the patients admitted to the hospital in terms of efficacy and safety.

What was done?

We implemented a pharmaceutical care project in a 153-bed regional hospital.

How was it done?

The pharmaceutical care project was based on 2 main strategies. The first of them was the validation of the treatment prescribed to inpatients according to their clinical situation. We planned to validate inpatient’s treatment from Monday to Friday during working hours.
The second one was the incorporation of the clinical pharmacist to hospital’s antimicrobial stewardship program. We established 2 meetings per week with the antimicrobial stewardship group. Revisions were focused on prescriptions of broad-spectrum antibiotics for more than 48 hours, antibiotic treatments longer than 7 days and prescriptions of aminoglycosides, vancomycin, and linezolid, among others.

What has been achieved?

During the 6 first months (January-June 2021), a total of 222 pharmaceutical interventions were performed, being the most frequent:
– “Discontinue medication” (22.97%), mainly because of “Undue duration” (31.37%) and “Therapeutic duplication” (29.41%)
– “Modify dose” (31.62%)
– “Change medication” (17.12%), mainly due to “Adjustment to antibiogram” (26.32%), “Medication exchange” (18.42%) and “Inadequate medication for the clinical situation of the patient” (15.79%).
The pharmaceutical intervention acceptance rate was 81.10%.

Related to the antimicrobial stewardship program, a total of 171 revisions were performed, making any treatment advice in 51 of them (29.82%). The most frequent recommendation was to “Discontinue treatment because of undue duration” (25.49%), followed by “Adjustment to antibiogram” (15.69%), “De-escalate treatment” (11.76%) and “Increment of antibiotic dose” (11.76%). Acceptance rate was 94%.

What next?

The pharmaceutical care program allows both the early identification of possible medication errors and upgrades in inpatients’ treatment.
