[Scoring tool to identify patients at increased risk for drug-related problems: results of a point prevalence study at hospital admission]. / Scoring-Tool zu Identifizierung von Patienten mit erhöhtem Risiko für Arzneimittel-bezogene Probleme- Bericht einer Punkt-Prävalenzuntersuchung bei Aufnahme im Krankenhaus.

INTRODUCTION: Drug therapy is a high-risk process and requires special attention, especially at sectoral borders. Pharmaceutical services such as medication review are appropriate measures to identify drug-related problems and thus improve the safety of drug therapy. Risk-scoring tools have been described in the literature as helpful for prioritizing medication reviews for patients at high risk for drug-related problems. METHODS: In a multi-centre point prevalence study, we identified patients at increased risk for medication-related problems at hospital admission using the medication risk tool. In addition, the current level of implementation of pharmacy services was surveyed. RESULTS: A total of 11 (58%; 11/19) hospital pharmacies in Saxony participated in the point prevalence survey. The scoring tool identified 32% (279/875) of patients at increased risk for medication-related problems (Meris score >12 group) at admission. Thereby, the number of drugs in the Meris score >12 group was 10.6 (average; standard deviation 3.5; n=279), while in the Meris score ≤12 group it was only five drugs per patient (average 4.6; standard deviation 2.8; n=596). The age of patients in the Meris score >12 group averaged 75.9 ± 11 years, while the age of patients in the Meris score ≤12 group averaged 60.6 ± 17.9 years. DISCUSSION: Prioritization with the help of a risk-scoring tool is essential as pharmacy services in Saxon hospitals still need to be regularly established and in order to identify patients with an increased risk for drug-related problems at an early stage.

Clinical pharmacy services in critical care: results of an observational study comparing ward-based with remote pharmacy services.

BACKGROUND: Pharmacists are essential team members in critical care and contribute to the safety of pharmacotherapy for this vulnerable group of patients, but little is known about remote pharmacy services in intensive care units (ICU). AIM: We compared the acceptance of pharmacist interventions (PI) in ICU patients working remotely with ward-based service. We evaluated both pharmacy services, including further information on PI, including reasons, actions and impact. METHOD: Over 5 months, a prospective single-centre observational study divided into two sequential phases (remote and ward-based) was performed on two ICU wards at a university hospital. After a structured medication review, PI identified were addressed to healthcare professionals. For documentation, the national database (ADKA-DokuPIK) was used. Acceptance was used as the primary endpoint. All data were analysed using descriptive methods. RESULTS: In total, 605 PI resulted from 1023 medication reviews. Acceptance was 75% (228/304) for remote and 88% (265/301; p < 0.001) for ward-based services. Non-inferiority was not demonstrated. Most commonly, drug- (44% and 36%) and dose-related (36% and 35%) reasons were documented. Frequently, drugs were stopped/paused (31% and 29%) and dosage changed (31% and 30%). PI were classified as "error, no harm" (National Coordinating Council for Medication Error Reporting and Prevention [NCC MERP] categories B to D; 83% and 81%). The severity and clinical relevance were at least ranked as "significant" (68% and 66%) and at least as "important" for patients (77% and 83%). CONCLUSION: The way pharmacy services are provided influences the acceptance of PI. Remote pharmacy services may be seen as an addition, but acceptance rates in remote services failed to show non-inferiority.

[Drug therapy safety supported by interprofessional collaboration between ICU physicians and clinical pharmacists in critical care units in Germany : Results of a survey]. / Arzneimitteltherapiesicherheit gefördert durch die interprofessionelle Zusammenarbeit von Arzt und Apotheker auf Intensivstationen in Deutschland : Erkenntnisse einer Umfrage.

BACKGROUND: Critically ill patients are particularly susceptible to adverse drug events. International studies show that pharmaceutical care has a positive impact on patient and drug therapy safety. Nationally, the integration of pharmacists into the multidisciplinary team and participation in ward rounds is required. The aim of this work is to assess the scope and extent of pharmaceutical care in intensive care units (ICU) in Germany. METHOD: In a literature and database search, 13 relevant pharmaceutical activities were identified. Based on this, an online survey with 27 questions on the implementation of pharmaceutical care in ICU was prepared by a panel of experts. The survey was sent to heads of German ICUs. RESULTS: Of the participants, 35.3% (59/167) have established regular pharmaceutical care. Drug information (89.7% [52/58]), pharmaceutical interventions with change of therapy (e.g., ward rounds; 67,2% [39/58]), regular evaluation of prescriptions (medication analysis; 65.5% [38/58]) as well as the monitoring of medication (e.g., side effects, effectiveness, costs; 63.8% [37/58]) were most frequently mentioned. The participants with pharmaceutical care (58/168) graded 7 of 13 but those without (104/168) only two  activities as 'essential/indispensable'. CONCLUSION: Only a few ICU in Germany have already integrated ward pharmacists into the multidisciplinary team. Once a pharmaceutical service has been established, a greater role/importance is assigned to several pharmaceutical activities.

Clinical pharmacists' interventions across German hospitals: results from a repetitive cross-sectional study.

Background Pharmacists' interventions (PI) are suitable to improve medication safety and optimise patient outcome. However, in Germany, clinical pharmacy services are not yet available nationwide. Aim To gain prospective data on the extent and the composition of routine PI with special focus on intervention rates among German hospital pharmacists during two intervention weeks. Methods Within a repetitive cross-sectional study, clinical pharmacists documented all PIs on five days during a one-month period (intervention week) in 2017 and 2019 using the validated online-database ADKA-DokuPIK. Additionally, data regarding the supply structure/level of medical care, the extent of clinical pharmacy services and their professional experience were collected. All data were anonymised before analysis. Results In total, 2,282 PI from 62 pharmacists (2017) and 2578 PI from 52 pharmacists (2019) were entered. Intervention rate increased from 27.5 PI/100 patient days in 2017 to 38.5 PI/100 patient days in 2019 (p = 0.0097). Frequency of clinical pharmacy services on a daily basis significantly increased from 60% (2017) to 83% (2019). Reasons for PIs from the categories "drugs" (e.g. indication, choice, documentation/transcription) and "dose" were most common in both intervention weeks. The vast majority of underlying medication errors in both intervention weeks were categorised as "error, no harm" (80.3 vs. 78.6%), while the proportion of errors which did not reach the patient, doubled to 39.8% in IW-2019. Conclusion Regular and daily clinical pharmacy services become more established in Germany and clinical pharmacists are increasingly involved in solving drug related problems proactively and early during the medication management process.

[Acute intoxications in the intensive care unit: A 10-year analysis]. / Akute Intoxikationen auf der Intensivstation: Eine 10-Jahres-Analyse.

BACKGROUND: Acute intoxications play a special role in preclinical emergency medicine, in the emergency department, and in intensive care. This study characterizes cases of acute intoxications from an intensive care perspective. OBJECTIVES: All cases of acute intoxications admitted to the intensive care units at the University Hospital Hamburg-Eppendorf between 01 January 2007 and 30 June 2017 were retrospectively analyzed. RESULTS: During the study period, 587 patients with acute intoxications were admitted to the university hospital's intensive care units. Median age was 45 years (interquartile range [IQR] 31 years); 83.1% of patients were younger than 70 years. The most common cause of intoxication in the younger patients was a suicide attempt (55.1%), while in older patients it was an iatrogenic event (47.5%). Cases involving intoxications with psychotropic medication (48.7%), alcohol (32.9%), analgesics (23.3%), and drugs (17.0%) were most frequent. In 50.6% of cases, intoxication was due to more than one substance. Intoxication-specific therapy was performed in 40.0% of cases and intensive care therapy in 42.4% of cases. The median length of intensive care unit stay was 2 days (IQR 3). Hospital mortality was 5.5%. In older patients (≥ 70 years) compared with younger patients, the need for intensive care treatment (56.6% vs. 39.5% of cases, p = 0.002), the length of intensive care unit stay (3 days [IQR 5] vs. 2 days [IQR 3], p = 0.0004) and in-hospital mortality (17.2% vs. 3.1%, p < 0.001) were significantly higher. CONCLUSIONS: Acute intoxications are part of the spectrum of disorders treated in the intensive care unit. In older patients, iatrogenic causes are frequently found, which is associated with an increased risk of death.

Clinically Relevant Interactions with Anti-Infectives on Intensive Care Units-A Multicenter Delphi Study.

Patients in intensive care units (ICUs) are at high risk of drug-drug interactions (DDIs) due to polypharmacy. Little is known about type and frequency of DDIs within German ICUs. Clinical pharmacists' interventions (PI) recorded in a national database (ADKA-DokuPIK) were filtered for ICU patients. Binary DDIs involving ≥1 anti-infective agent with >1 database entry were selected. A modified two-step Delphi process with a group of senior hospital pharmacists was employed to evaluate selected DDIs for clinical relevance by using a five-point scale and to develop guidance for clinical practice. In total, 16,173 PI were recorded, including 1836 (11%) DDIs in the ICU setting. Of the latter, 41% (756/1836) included ≥1 anti-infective agent, 32% (590/1836) were binary DDIs, and 25% (455/1836) were listed at least twice. This translates into 88 different DDIs, 74% (65/88) of which were rated as being clinically relevant by our expert panel. The majority of DDIs (76% [67/88]) included macrolides, antifungals, or fluoroquinolones. This percentage was even higher in DDIs being rated as clinically relevant by the experts (85% [55/65]). It is noted that an inter-professional discussion and approach is needed in the individual patient management of DDIs. The guidance developed might be a tool for decision support.

Emergence of linezolid-resistance in vancomycin-resistant Enterococcus faecium ST117 associated with increased linezolid-consumption.

OBJECTIVE: We aim to describe the epidemiological, clinical and microbiological characteristics of the linezolid- and vancomycin- resistant Enterococcus faecium (LVRE) in a tertiary care hospital in Germany. METHODS: We conducted a retrospective analysis of 196 LVRE cases observed from 1st January 2012 to 31th December 2018. Patients' medical charts were reviewed and available LVRE (n = 102) were subjected to whole-genome-sequencing. Antibiotic consumption was measured in defined daily dose (DDD)/100 bed-days (BD). RESULTS: The prevalence of LVRE isolates among VRE was 6.3 % in 2018. Most patients had an onco-hematological disease (134/196, 68.4 %). From 2012-2018 an increase of +356.7 % of linezolid defined daily dose/100 bed-days was observed. In 71.4 % (90/126, 70 missing values) of the patients, linezolid was prescribed in the previous 6 months. The median exposure to linezolid was 15 days (Interquartile, IQR 9-23). 42/196 (21.4 %) patients had an LVRE-related infection with an overall 30-day mortality rate of 33 %. In 121/196 (61.7 %) patients, linezolid-susceptible VREfm were isolated before LVRE, suggesting secondary acquisition of linezolid resistance. Genetic analysis revealed that most isolates belonged to ST117 (64/102 available isolates, 62.7 %). The G2576T 23S rDNA mutation was identified as the most common resistance mechanism (96/102, 94.1 %). poxtA was identified in two isolates, while cfr, and optrA were not detected. CONCLUSIONS: Incidence of LVRE related to 23S rDNA mutations is rising and probably associated with antibiotic consumption. Restrictions in the use of linezolid may be needed in order to retain therapeutic options in VRE.

Prospective survey-based study on the categorization quality of hospital pharmacists' interventions using DokuPIK.

Background There is a growing need to categorize pharmacists' interventions (PIs) in Germany to document their impact on solving or avoiding drug-related problems. Objective To validate the categorization of drug-related problems-one aspect of the categorical internet database DokuPIK, designed for recording routinely PIs. To identify case-specific predictive values. Setting German hospitals. Methods Within a prospective, nationwide survey-based study, 37 of 498 registered database users volunteered to evaluate 24 standardized case reports independently. Case evaluation was restricted to classify problems, based on 26 given categories with no limit on the number of item choices. Ratings were conducted electronically and anonymously. A gold standard of one or more problems per case was developed by majority consensus of five senior clinical pharmacists. Agreement of raters' case classification with the gold standard was assessed by calculating sensitivity, specificity and positive and negative predictive value and was reported as median and range. Main outcome Level of agreement. Results Independent assessment yielded a median agreement of 90% [79-94%]. Sensitivity and specificity were 37% [21-57%] and 99% [97-100%], respectively. Median positive and negative predicted value were both 90% [60-100%] and 90% [78-95%]. Mean case-specific agreement was robust (≥ 79%) with respect to a majority and maximum consensus (three and five out of five raters). Conclusion DokuPIK seems to have a high level of agreement and a good specificity according to the majority of clinical pharmacists in a panel of assessors. Despite the allowance of multiple choices, predictive values were high and indicated a well-constructed classification by pharmacists.

Nationwide evaluation of day-to-day clinical pharmacists' interventions in German hospitals.

STUDY OBJECTIVE: To describe and evaluate the extent and diversity of nationwide data from clinical pharmacists' interventions (PIs) in German hospitals. DESIGN: Retrospective analysis. DATA SOURCE: The ADKA-DokuPIK German database, a national anonymous self-reported Internet-based documentation system for routine PIs as well as for medication errors reported by German hospital pharmacists. MEASUREMENTS AND MAIN RESULTS: Data sets from ADKA-DokuPIK entered between January 2009 and December 2012 were analyzed descriptively. A total of 27,610 PIs were entered, mainly by ward-based clinical pharmacists (82.5%). Most of the PIs were performed on surgical wards (37.8%), followed by anesthesiology/intensive care unit/intermediate care unit and internal medicine. The most prevalent therapeutic subgroup that was the trigger for the PIs was antibacterials for systemic use (13.9%), followed by antithrombotic agents, analgesics, drugs for acid-related disorders, and agents acting on the renin-angiotensin system. About a quarter of interventions (23.4%) were performed due to inappropriate use of drugs, followed by use of a wrong dose or administration interval (22.1%), resulting in the most frequently taken actions of change of dose, change of drug, and drug stopped/paused (withheld). Altogether, the implementation rate of the PIs was 85.5%. Underlying medication errors were predominantly classified as "error, no harm" according to the National Coordinating Council for Medication Error Reporting and Prevention. CONCLUSION: For the first time in a European country, our findings show the scope of clinical pharmacist involvement in patient care in daily clinical practice and demonstrate the usefulness and importance of their proactive interventions in the prevention of hazards and risks for hospital inpatients.

Do centrally pre-prepared solutions achieve more reliable drug concentrations than solutions prepared on the ward?

PURPOSE: To compare the concentration conformity of infusion solutions manually prepared on intensive care units (ICU) with solutions from pharmacy-based, automated production. METHODS: A prospective observational study conducted in a university hospital in Germany. Drug concentrations of 100 standardised infusion solutions manually prepared in the ICU and 100 matching solutions from automated production containing amiodarone, noradrenaline or hydrocortisone were measured by high-performance liquid chromatography analysis. Deviations from stated concentrations were calculated, and the quality of achieved concentration conformity of the two production methods was compared. RESULTS: Actual concentrations of 53% of the manually prepared and 16% of the machine-made solutions deviated by >5% above or below the stated concentration. A deviation of >10% was measured in 22% of the manually prepared samples and in 5% of samples from automated production. Of the manually prepared solutions, 15% deviated by >15% above or below the intended concentration. The mean concentration of the manually prepared solutions was 97.2% (SD 12.7%, range 45-129%) and of the machine-made solutions was 101.1% (SD 4.3%, range 90-114%) of the target concentration (p < 0.01). CONCLUSIONS: In this preliminary study, ward-based, manually prepared infusion solutions showed clinically relevant deviations in concentration conformity significantly more often than pharmacy-prepared, machine-made solutions. Centralised, automated preparation of standardised infusion solutions may be an effective means to reduce this type of medication error. Further confirmatory studies in larger settings and under conditions of routine automated production are required.

Clinical pharmacists' interventions in a German university hospital.

OBJECTIVE: To evaluate pharmaceutical interventions by ward-based clinical pharmacists in Germany. SETTING: Two ward-based clinical pharmacists working at the Departments of Stem Cell Transplantation and Intensive Care Medicine. METHODS: Pharmaceutical interventions during ward rounds from December 1st 2006 to November 30th 2008 were recorded and classified according to our own system that was adopted from established classification systems. MAIN OUTCOME MEASURE: Classification of (1) cause of intervention, (2) intervention, (3) outcome of intervention and (4) initiator of intervention. RESULTS: Altogether 2,312 interventions were documented. Besides 520 cases of information about drugs (rational selection, occurrence of infrequent adverse events or interactions), the main interventions were recommendations for the addition, the withdrawal or the replacement of a drug (n = 907, 50.6%) and advice for the change of dosage, dosing intervals or dose adjustment according to impaired renal or liver function (n = 584, 32.6%). The vast majority of the suggested interventions (92.8%) have been accepted. CONCLUSION: The participation of a clinical pharmacist during ward rounds contributes to the optimisation of pharmacotherapy, in terms of choosing the most appropriate drug and/or the suitable dosage and may improve patient care.
