Can the Heinrich ratio be used to predict harm from medication errors?

The purpose of this study was to establish whether, for medication errors, there exists a fixed Heinrich ratio between the number of incidents which did not result in harm, the number that caused minor harm, and the number that caused serious harm. If this were the case then it would be very useful in estimating any changes in harm following an intervention. Serious harm resulting from medication errors is relatively rare, so it can take a great deal of time and resource to detect a significant change. If the Heinrich ratio exists for medication errors, then it would be possible, and far easier, to measure the much more frequent number of incidents that did not result in harm and the extent to which they changed following an intervention; any reduction in harm could be extrapolated from this

A survey about label enhancement methods for parenteral medication in European hospital pharmacies

Purpose Unclear labeling has been recognized as an important cause of look-alike medication errors. Little is known about which labeling practices are currently used in European hospitals. The aim of this article is to obtain an overview of the labeling practices for parenteral medications, in relation to national guidelines, in the Netherlands, Germany, and the UK. Methods An online survey was conducted using the Qualtrics (R) software. The survey was distributed to hospital pharmacists in the Netherlands, Germany, and the UK. The results were downloaded from Qualtrics and exported to Microsoft Excel. Data were categorized into groups and analyzed descriptively. Results In total, 104 responses were received. The response rate was 63% (n= 48) in the Netherlands and 11% (n= 41) for Germany; for the UK, 15 responses were received. In general almost 90% of the respondents followed the National guidelines concerning labeling of pharmacy-prepared parenteral products. The use of label enhancement techniques was relatively low in all countries. On average, the use of "Tall Man" lettering was 19%, the use of color coding was 29%, and the use of a barcode on the label was 27%. Conclusion Label-enhancement methods for parenteral medication in hospital pharmacies do not seem to be widely implemented and acknowledged in European hospitals, but response rates were limited for two countries. Greater standardization in conjunction with research for evidence-based enhancement techniques is needed to guide improvement in labeling practices across Europe

The incidence of metabolic syndrome and its reversal in a cohort of schizophrenic patients followed for one year

Cross-sectional studies showed a high prevalence of metabolic syndrome in patients with schizophrenia. This study aimed to identify the incidence of metabolic syndrome and its reversal in a non-preselected cohort of chronic psychotic patients in routine practice in one year follow-up and to find variables to describe development and reversal of metabolic syndrome. This cohort study was conducted as part of a disease management program and patients were included if they had two complete assessments in a one year follow-up. We conducted two logistic regressions to find variables to describe the development of metabolic syndrome and the reversal of metabolic syndrome. At the time of the first assessment 35% (n = 92) of the 260 included patients had metabolic syndrome. Within one year 21 patients developed metabolic syndrome and 30 patients had it reversed. This was an incidence of 13% (21/168) and a reversal of 33% (30/92). Smoking, family history of cardiovascular diseases, and duration of disease >6 years was associated with a higher risk of developing metabolic syndrome as well as abdominal obesity and dyslipidemia. Patients with abdominal obesity had a smaller chance of reversing metabolic syndrome. Other variables included in the logistic regression such as receiving cardiovascular/antidiabetic drug treatment or duration of disease >6 years did not alter the risk of reversing the metabolic syndrome. Our study showed that the natural course of metabolic syndrome is dynamic. A considerable number of patients developed or reversed the metabolic syndrome in one year follow-up. (C) 2009 Elsevier Ltd.

Costs of ownership of ready-to-administer pre-filled sterilized syringes in a Dutch hospital:A cost minimization analysis

Objectives: Preparation errors occur frequently during conventional multiple step preparation of parenteral drugs at the bedside, causing potential adverse drug events (ADEs), which can be a burden to the patient and involves high costs for the national healthcare system. The use of ready-to-administer (RTA) pre-filled sterilized syringes (PFSS) produced by the hospital pharmacy can prevent a significant part of preparation errors and reduces the risk of bacteremia due to contamination of the intravenous fluid. This research aims to compare the total cost of the conventional preparation methods (CPM) with the PFSS method. Methods: In the analysis, costs related to the preparation of the drugs, bacteremia due to contamination, ADEs as a result of medication errors and wastage of syringes were taken into account. Annual costs in a general Dutch hospital were consistently calculated. Three scenarios were investigated: (i) all preparations CPM (864.246 administrations per year); (ii) all preparations as PFSS; and (iii) 200.000 PFSS and the remaining part CPM (reflecting a transition state as currently present). Deterministic and probabilistic analyses are performed. Results: The first scenario shows higher annual costs at € 10.862.609 compared to the second scenario. The current situation (third scenario) already shows savings of € 2.420.545 compared to the old situation (first scenario). Sensitivity analyses revealed that cost savings of PFSS were mainly the result of decreased risks of medication errors and contamination of intravenous fluids. Extrapolating these results nationwide indicates potential savings over € 300 million if only PFSS were used Conclusions: The use of PFSS prepared at the hospital pharmacy yielded cost-savings compared to conventional preparation at the bedside in the Dutch hospital

Reducing the anticholinergic and sedative load in older patients on polypharmacy by pharmacist-led medication review: A randomised controlled trial

© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved. No commercial use is permitted unless otherwise expressly granted. Objective To evaluate if a pharmacist-led medication review is effective at reducing the anticholinergic/sedative load, as measured by the Drug Burden Index (DBI). Design Randomised controlled single blind trial. Setting 15 community pharmacies in the Northern Netherlands. Participants 157 community-dwelling patients aged ≥65 years who used ≥5 medicines for ≥3 months, including at least one psycholeptic/psychoanaleptic medication and who had a DBI≥1. Intervention A medication review by the community pharmacist in collaboration with the patient's general practitioner and patient. Primary and secondary outcomes measures The primary outcome was the proportion of patients whose DBI decreased by at least 0.5. Secondary outcomes were the presence of anticholinergic/sedative side effects, falls, cognitive function, activities of daily living, quality of life, hospital admission and mortality. Data were collected at baseline and 3 months follow-up. Results Mean participant age was 75.7 (SD, 6.9) years in the intervention arm and 76.6 (SD, 6.7) years in the control arm, the majority were female (respectively 69.3% and 72.0%). Logistic regression analysis showed no difference in the proportion of patients with a≥0.5 decrease in DBI between intervention arm (17.3%) and control arm (15.9%), (OR 1.04, CI 0.47 to 2.64, p=0.927). Intervention patients scored higher on the Digit Symbol Substitution Test, measure of cognitive function (OR 2.02, CI 1.11 to 3.67, p=0.021) and reported fewer sedative side effects (OR 0.61, CI 0.40 to 0.94, p=0.024) at follow-up. No significant difference was found for other secondary outcomes. Conclusions Pharmacist-led medication review as currently performed in the Netherlands was not effective in reducing the anticholinergic/sedative load, measured with the DBI, within the time frame of 3 months. Preventive strategies, signalling a rising load and taking action before chronic use of anticholinergic/sedative medication is established may be more successful.

A 12-month follow-up study of treating overweight schizophrenic patients with aripiprazole

Objective: To investigate the feasibility of switching overweight schizophrenic patients to aripiprazole and to assess the impact of 12 months of aripiprazole treatment on weight in routine practice. Method: This was a non-controlled cohort study in overweight schizophrenic patients. Data were collected before treatment with aripiprazole was started and at 12-month follow-up. Results: A total of 53 patients were included; of these 55% continued using aripiprazole for 12 months. Aripiprazole treatment for 12 months (P = 0.027) and stopping clozapine or olanzapine treatment (P = 0.038) predicted weight loss (>= 3 kg). Patients receiving aripiprazole monotherapy (n = 16, mean -3.0 kg) had similar weight loss than patients receiving aripiprazole in addition to another antipsychotic drug (n = 13, mean -4.4 kg). Conclusion: In routine practice once aripiprazole treatment was started, more than half of the patients remained on aripiprazole and most of them lost weight. Adding aripiprazole to clozapine gave similar weight loss as monotherapy with aripiprazole

The course of depressive symptoms and prescribing patterns of antidepressants in schizophrenia in a one-year follow-up study

AbstractBackgroundAntidepressants are frequently prescribed in patients with psychotic disorders, but little is known about their effects in routine clinical practice. The objective was to investigate the prescribing patterns of antidepressants in relation to the course of depressive symptoms in patients with psychotic disorders.MethodsA cohort of 214 Dutch patients with psychotic disorders received two assessments of somatic and psychiatric health, including a clinician-rated screening for depressive symptoms, as part of annual routine outcome monitoring.ResultsDepressive symptoms were prevalent among 43% (93) of the patients. Antidepressants were prescribed for 40% (86) of the patients and the majority 83% (71) continued this therapy after one year. Multivariable analysis showed that patients with more severe psychopathology had a higher risk to develop depressive symptoms the following year (OR [95% CI]=0.953 [0.912–0.995]). For patients with depressive symptoms at baseline, polypharmacy was a potential risk factor to keep having depressive symptoms (OR [95% CI]=1.593 [1.123–2.261]). Antidepressant use was not an independent predictor in both analyses.ConclusionsRoutine outcome monitoring in patients with psychotic disorders revealed a high prevalence of depressive symptoms. Antidepressants were frequently prescribed and continued in routine clinical practice

Medication safety in patients with hepatic impairment: A survey of community pharmacists’ knowledge level and their practice in caring for these patients

Aims: To study community pharmacists' level of knowledge on medication safety in patients with hepatic impairment and their practice in caring for these patients. Methods: Pharmacists from Dutch community pharmacies (n = 1545) were invited to participate in an online survey. The survey consisted of 27 questions covering 2 main topics: knowledge and current practice. The level of knowledge was measured by a 6-item knowledge test. Multiple linear regression was used to identify predictors of correctly answered responses. Results: In total, 338 pharmacists (22%) completed the questionnaire. The mean knowledge score was 2.8 (standard deviation 1.6). Only 30.3% of respondents were able to appropriately advise on use of analgesics in severe cirrhosis. Postgraduate education on hepatic impairment, knowledge of recently developed practical guidance, and fewer years of practice were associated with a higher level of knowledge. In total, 70.4% indicated to evaluate medication safety in a patient with hepatic impairment at least once weekly. In the past 6 months, 83.3% of respondents consulted a prescriber about a patient with hepatic impairment. Frequently encountered barriers in practice were insufficient knowledge on the topic and a lack of essential patient information (i.e. diagnosis and severity of the impairment). Conclusion: Community pharmacists regularly evaluate the safety of medication in patients with hepatic impairment, yet their level of knowledge was insufficient and additional education is needed. Pharmacists experienced several difficulties in providing pharmaceutical care. If these issues are resolved, pharmacists can play a more active role in ensuring medication safety in their patients with hepatic impairment
