Standardized Solutions of Catecholamines in Intensive Care Medicine: Application, Safety and Economic Aspects

Background/Objectives: Catecholamines are among those agents that are indispensable in modern intensive care medicine. The rapid availability of hygienically impeccable and correctly concentrated injectable solutions, e.g., for syringe pumps, is becoming more and more important. However, little research has been conducted regarding how the use of catecholamines is distributed in different wards and what options can be used to achieve optimal availability. Methods: In a retrospective monocentric study from 2019 to 2022, all continuously applied catecholamines in intensive care units (ICU) and intermediate care units (IMC) were investigated. The focus was on potential optimization by utilizing manufactured ready-to-administer solutions in the context of the economization of patient care. Results: Norepinephrine syringes represented 81% of all syringes administered, appearing to be the most frequently used on all wards. Production by the in-house pharmacy showed both financial advantages and an increase in patient safety compared to syringes produced at the bedside. Discussion: Increasing numbers of critically ill patients coupled with growing staff shortages and an increased awareness of safety requirements are driving the move towards ready-to-use and ready-to-administer solutions in critical care medicine. In-house manufacturing by hospital pharmacies can be a promising option to optimize processes and improve the economics of patient care. Conclusions: Individual calculations of the required catecholamine preparations with regard to possible economic advantages should be carried out in hospitals. In particular, in-house production of ready-to-use and ready-to-administer preparations could significantly increase patient safety and seems to be economically viable.

[Application and control of intravenous fluids in German intensive care units : A national survey among critical care physicians]

BACKGROUND

The administration of intravenous fluids includes various indications, e.g., fluid replacement, nutritional therapy or as a solvent for drugs and is a common routine in the intensive care unit (ICU); however, overuse of intravenous fluids can lead to fluid overload, which can be associated with a poorer outcome in critically ill patients.

OBJECTIVE

The aim of this survey was to find out the current status of the use and management of intravenous fluids as well as the interprofessional cooperation involving clinical pharmacists on German ICUs.

METHODS

An online survey with 33 questions was developed. The answers of 62 participants from the Scientific Working Group on Intensive Care Medicine of the German Society for Anesthesiology and Intensive Care Medicine were evaluated.

RESULTS

Fluid overload occurs "frequently" in 62.9% (39/62) and "very frequently" in 9.7% (6/62) of the ICUs of respondents. An established standard for an infusion management system is unknown to 71.0% (44/62) of participants and 45.2% of the respondents stated that they did not have a patient data management system. In addition, the participants indicated how they define fluid overload. This was defined by the presence of edema by 50.9% (28/55) and by positive fluid balance by 30.9% (17/55). According to the participants septic patients (38/60; 63.3%) and cardiological/cardiac surgical patients (26/60; 43.3%) are most susceptible to the occurrence of fluid overload. Interprofessional collaboration among intensive care physicians, critical care nurses, and clinical pharmacists to optimize fluid therapy was described as "relevant" by 38.7% (24/62) and "very relevant" by 45.2% (28/62). Participants with clinical pharmacists on the wards (24/62; 38.7%) answered this question more often as "very relevant" with 62.5% (15/24).

CONCLUSION

Fluid overload is a frequent and relevant problem in German intensive care units. Yet there are few established standards in this area. There is also a lack of validated diagnostic parameters and a clear definition of fluid overload. These are required to ensure appropriate and effective treatment that is tailored to the patient and adapted to the respective situation. Intravenous fluids should be considered as drugs that may exert side effects or can be overdosed with severe adverse consequences for the patients. One approach to optimize fluid therapy could be achieved by a fluid stewardship corresponding to comparable established procedures of the antibiotic stewardship. In particular, fluid stewardship will contribute to drug safety of intravenous fluids profiting from joined expertise in a setting of interprofessional collaboration. An important principle of fluid stewardship is to consider intravenous fluids in the same way as medication in terms of their importance. Furthermore, more in-depth studies are needed to investigate the effects of interprofessional fluid stewardship in a prospective and controlled manner.

[Ward-based clinical pharmacists in intensive care medicine: an economic evaluation]

BACKGROUND

The positive impact of pharmaceutical care in improving medication safety is considered proven. Little is known about the economic benefit of clinical pharmaceutical services in Germany.

OBJECTIVE

In 2020, a pilot project was started at the Ernst von Bergmann Hospital to introduce ward-based clinical pharmacists in intensive care medicine, also in order to determine the economic benefit of the medication management offered.

METHODS

By a team of experienced intensive care physicians and clinical pharmacists on the basis of a consensus principle, each pharmaceutical intervention (PI) was assigned a probability score (Nesbit probability score) with which an adverse drug event (ADE) would have occurred. Assuming that each ADE results in an increased length of stay, the costs of intensive care treatment/day were used as potential savings. The model thereby combines the findings of two international publications to enable an economic analysis of pharmaceutical services.

RESULTS

During the study period, 177 pharmaceutical interventions were evaluated and corresponding probability scores for the occurrence of ADE were determined. From this, annual savings of € 80,000 through avoided costs were calculated.

CONCLUSION

In this project, the economic benefit of pharmaceutical services in intensive care medicine was proven. Ward-based clinical pharmacists are now an integral part of the intensive care treatment team at the Ernst von Bergmann Hospital.

Comparison of Drug-Related Problems in COVID-19 and Non-COVID-19 Patients Provided by a German Telepharmacy Service for Rural Intensive Care Units

Telepharmacy is used to bridge the persisting shortage of specialist ward-based pharmacists, particularly in intensive care units (ICU). During the coronavirus disease 2019 (COVID-19), pharmacotherapy was rapidly developed, which resulted in multiple changes of guidelines. This potentially led to a differing risk for drug-related problems (DRPs) in ICUs. In this study, DRPs were detected in telepharmacy consultations of a German state-wide telemedicine network for adult patients in rural ICUs. The analysis included ICUs of ten general care hospitals with a total of 514 patients and 1056 consultations. The aim of this retrospective, observational cohort study was to compare and analyze the DRPs resulting from ICU patients with or without COVID-19. Furthermore, known risk groups for severe COVID-19 progression (organ insufficiency [kidney, liver], obesity, sex, and/or older age) were investigated with their non-COVID-19 counterparts. As a result, in both groups patients with acute renal insufficiency and without renal replacement therapy showed a significantly higher risk of being affected by one or more DRPs compared to patients with normal renal function. In COVID-19 patients, the initial recommendation of therapeutic anticoagulation (ATC-code B01AB 'Heparin group') resulted in significantly more DRPs compared to non-COVID-19 patients. Therefore, COVID-19 patients with therapeutic anticoagulation and all ICU patients with renal insufficiency should be prioritized for telepharmacy consultations.

Standardkonzentrationen für Dauerinfusionen – Ergebnisse einer bundesweiten Befragung auf deutschen Erwachsenenintensivstationen

Hintergrund

Intensivpatienten erhalten zahlreiche Arzneimittel (AM) als Dauerinfusion appliziert. In Deutschland fehlt bisher für die als Dauerinfusion applizierten AM eine einheitliche Liste mit Standardkonzentrationen.

Ziel der Arbeit

Ziel war es, bundesweit repräsentative Informationen zu Standardkonzentrationen von als Dauerinfusion mittels Spritzenpumpe oder Infusionspumpe applizierten AM auf den Intensivstationen zu gewinnen.

Material und Methoden

Zur Ermittlung der Akzeptanz und Präferenz für Dauerinfusionen von ausgewählten AM wurde ein Fragenkatalog in einem online- Umfragetool entwickelt und von der DIVI an die jeweils verantwortlichen Leiter*innen von 1816 Intensivstationen versendet. Die Umfrage umfasste Vorschläge zu 59 AM mit insgesamt 73 Konzentrationen. Ergänzend konnten die Teilnehmer in Freitextfeldern eigene Vorschläge zu AM und entsprechenden Konzentrationen angeben. Die Häufigkeit der Verwendung der Arzneimittel als Dauerinfusion und der präferierten Standardkonzentrationen wurde bezogen auf die Zahl der Antworten pro Arzneimittel berechnet.

Ergebnisse

Die Umfrage wurde von 312 (17 %) Intensivstationen beantwortet. Die Akzeptanzrate für das Prinzip der geschwindigkeitsgesteuerten Dauerinfusion in Standardkonzentrationen ist deutschlandweit sehr hoch, Die Top 10 bzw. 25 der vorgeschlagenen AM werden von über 90 % bzw. 50 % der Teilnehmer regelmäßig als Dauerinfusion eingesetzt. Für viele dieser AM konnte eine oder mehrere präferierte Konzentrationen identifiziert werden.

Diskussion

Die Top-37-Arzneimittel und die präferierten Konzentrationen sind als Grundlage für eine bundesweit geltende Standardliste mit Standardkonzentrationen für Dauerinfusionen (in der Regel 50 ml) geeignet. Die damit befassten Fachgesellschaften können basierend auf den Umfrageergebnissen eine bundeseinheitliche Standardliste konsentieren.
