Effects of training physicians in electronic prescribing in the outpatient setting on clinical, learning and behavioural outcomes: a cluster randomized trial.

AIMS: Electronic prescribing systems may improve medication safety, but only when used appropriately. The effects of task analysis-based training on clinical, learning and behavioural outcomes were evaluated in the outpatient setting, compared with the usual educational approach. METHODS: This was a multicentre, cluster randomized trial [EDUCATional intervention for IT-mediated MEDication management (MEDUCATE trial)], with physicians as the unit of analysis. It took place in the outpatient clinics of two academic hospitals. Participants comprised specialists and residents (specialty trainees, in the UK) and their patients. Training took the form of a small-group session and an e-learning. The primary outcome was the proportion of medication discrepancies per physician, measured as discrepancies between medications registered by physicians in the electronic prescribing system and those reported by patients. Clinical consequences were estimated by the proportion of patients per physician with at least one missed drug-drug interaction with the potential for causing adverse drug events. A questionnaire assessed physicians' knowledge and skills. RESULTS: Among 124 participating physicians, primary outcome data for 115 (93%) were available. A total of 1094 patients were included. A mean of 48% of registered medications per physician were discrepant with the medications that their patients reported in both groups (P = 0.14). Due to registration omissions, a mean of 4% of patients per physician had one or more missed drug-drug interactions with the potential to cause a clinically relevant adverse drug event in the intervention group, and 7% in controls (P = 0.11). The percentages of correct answers on the knowledge and skills test were higher in the intervention group (57%) compared with controls (51%; P = 0.01). CONCLUSION: The training equipped outpatient physicians with the knowledge and skills for appropriate use of electronic prescribing systems, but had no effect on medication discrepancies.

MEDUCATE trial: effectiveness of an intensive EDUCATional intervention for IT-mediated MEDication management in the outpatient clinic - study protocol for a cluster randomized controlled trial.

BACKGROUND: Using information technology for medication management is an opportunity to help physicians to improve the quality of their documentation and communication and ultimately to improve patient care and patient safety. Physician education is necessary to take full advantage of information technology systems. In this trial, we seek to determine the effectiveness of an intensive educational intervention compared with the standard approach in improving information technology-mediated medication management and in reducing potential adverse drug events in the outpatient clinic. METHODS/DESIGN: We are conducting a multicenter, cluster randomized controlled trial. The participants are specialists and residents working in the outpatient clinic of internal medicine, cardiology, pulmonology, geriatrics, gastroenterology and rheumatology. The intensive educational intervention is composed of a small-group session and e-learning. The primary outcome is discrepancies between registered medication (by physicians) and actually used medication (by patients). The key secondary outcomes are potential adverse events caused by missed drug-drug interactions. The primary and key secondary endpoints are being assessed shortly after the educational intervention is completed. Sample size will be calculated to ensure sufficient power. A sample size of 40 physicians per group and 20 patients per physician will ensure a power of >90 %, which means we will need a total of 80 physicians and 1,600 patients. DISCUSSION: We performed an exploratory trial wherein we tested the recruitment process, e-learning, time schedule, and methods for data collection, data management and data analysis. Accordingly, we refined the processes and content: the recruitment strategy was intensified, extra measures were taken to facilitate smooth conductance of the e-learning and parts were made optional. First versions of the procedures for data collection were determined. Data entry and analysis was further standardized by using the G-standard database in the telephone questionnaire. TRIAL REGISTRATION: ISRCTN registry: ISRCTN50890124 . Registered 10 June 2013.

Task analysis of information technology-mediated medication management in outpatient care.

AIMS: Educating physicians in the procedural as well as cognitive skills of information technology (IT)-mediated medication management could be one of the missing links for the improvement of patient safety. We aimed to compose a framework of tasks that need to be addressed to optimize medication management in outpatient care. METHODS: Formal task analysis: decomposition of a complex task into a set of subtasks. First, we obtained a general description of the medication management process from exploratory interviews. Secondly, we interviewed experts in-depth to further define tasks and subtasks. SETTING: Outpatient care in different fields of medicine in six teaching and academic medical centres in the Netherlands and the United States. PARTICIPANTS: 20 experts. Tasks were divided up into procedural, cognitive and macrocognitive tasks and categorized into the three components of dynamic decision making. RESULTS: The medication management process consists of three components: (i) reviewing the medication situation; (ii) composing a treatment plan; and (iii) accomplishing and communicating a treatment and surveillance plan. Subtasks include multiple cognitive tasks such as composing a list of current medications and evaluating the reliability of sources, and procedural tasks such as documenting current medication. The identified macrocognitive tasks were: planning, integration of IT in workflow, managing uncertainties and responsibilities, and problem detection. CONCLUSIONS: All identified procedural, cognitive and macrocognitive skills should be included when designing education for IT-mediated medication management. The resulting framework supports the design of educational interventions to improve IT-mediated medication management in outpatient care.

The uptake of recombinant Factor VIII in the Netherlands.

In comparison with other biotechnology substitutions, the adoption of recombinant Factor VIII (rFVIII) has been relatively slow. We sent a postal questionnaire to all Dutch haemophilia patients and haemophilia-treating physicians, to determine which factors predict whether a patient uses plasma-derived FVIII (pdFVIII) or rFVIII and to investigate patients' and doctors' opinions on both products. Fifty-six per cent of patients received rFVIII. This percentage varied widely between centres. Only one doctor would choose to use pdFVIII if he suffered from haemophilia A himself, and 74% would choose to use rFVIII. Younger patients, those not infected with the human immunodeficiency virus or hepatitis C, and those who did not have family members who used pdFVIII switched more often from pdFVIII to rFVIII. Patients who rated themselves as innovative, who had family members who used rFVIII, and those who were treated in a large haemophilia treatment centre were also more likely to have switched. For physicians and patients alike, the respondents generally did not see large differences between rFVIII and pdFVIII, except for the risk of infections and the knowledge of long-term effects (both larger for pdFVIII). Although haemophilia patients represent one of the most empowered patient groups, physicians appear to have been influential in choosing between pdFVIII and rFVIII.

Variability in abciximab (ReoPro) prescribing: evidence based or budget driven?

PURPOSE: Abciximab improves outcomes in patients undergoing percutaneous transluminal coronary intervention (PTCA). Clinicians, however, have expressed concerns that they do not have enough budget to administer abciximab to all eligible patients. We studied the patterns of prescribing of abciximab and identified factors that correlate with the level of usage. METHODS: In each of all 13 Dutch PTCA centres one opinion-leading cardiologist was approached to provide data on the abciximab prescribing in their centre and to co-operate in an interview on this topic. We performed linear regression analysis in which the level of abciximab prescribing was the dependent variable. Potential determinants investigated were the number of PTCAs performed, the criteria for abciximab prescribing, funding and possible financial restrictions, participation in clinical trials in the past, percentage stenting, and desired level of abciximab prescribing. RESULTS: All 13 PTCA centres in the Netherlands participated in our study. The level of abciximab prescribing varied from 2 to 36% of all PTCAs. The criteria for patient selection significantly differed between centres. Together budget, investigatorship, size, and type of the institution were highly predictive for the level of abciximab prescribing (R2 = 0.93, p < 0.001). The more patients doctors had included in clinical trials in the past, the higher was the likelihood that they had prescribed abciximab. CONCLUSIONS: Shortly after its introduction, patterns of abciximab prescribing varied widely between PTCA centres. There was no agreement on which patients to select for this preventive treatment. Budget and involvement in clinical trials in the past were important predictors of the level of prescribing in each centre.

From HMG through purified urinary FSH preparations to recombinant FSH: a substitution study.

Drugs produced through the use of recombinant DNA techniques have become an integral part of medical practice. Before recombinant FSH (rFSH) was introduced in 1996, FSH purified from the urine of postmenopausal women had been commercially available since the 1960s. We analysed the diffusion and the substitution patterns of the different FSH preparations in The Netherlands. The fact that rFSH preparations have batch-to-batch consistency, are free from urinary protein contaminants and have the potential to be produced in limitless quantities, is advantageous. The question whether newer, more pure FSH products are beneficial from the clinical perspective, has not been settled beyond reasonable doubt. The price of rFSH is three times as high as the price of the former FSH preparations. Due to the introduction of rFSH, total FSH expenditures have grown from 5.0 million Euros in 1995, to 26.8 million Euros in 2000, while the volume increased by <100%. Both the pharmaceutical companies and purchasers (government, insurers) have influenced the patterns of substitution of existing FSH products by biotech equivalents. In general, the risk of increasing pharmaceutical costs without clear clinical benefits has to be set against the risk of strangling innovations. Therefore, a continuous process of technology assessment is necessary.

[Rising costs of drugs in hospitals in the period 1996-2000 and over the next few years]. / Stijegende kosten van geneesmiddelen in ziekenhuizen in 1996-2000 en in de komende jaren.

OBJECTIVE: To obtain an impression of drug expenditure in hospitals and in particular the costs due to novel more expensive drugs both in the past and in the future. DESIGN: Descriptive. METHOD: Data on intramurally supplied drugs were collected from 6 of the 95 general hospitals, 5 of the 14 top clinical hospitals, 4 of the 8 university hospitals and I of the 13 categorical hospitals for the period 1 January 1996-31 December 2000. The data were extrapolated to the entire of the Netherlands per hospital category and per year on the basis of the adherence figures. The drug costs were calculated on the basis of cost prices. For the most important new potential drugs it was ascertained whether they would actually become available and if they would substantially contribute to the drug expenditure. RESULTS: In 2000, the total drug expenditure within all Dutch hospitals was estimated to be [symbol: see text] 402 million. A substantial part of the costs could be attributed to the use of anticancer drugs (19%) and antibiotics (14%). In 2000, about 12% of the drug expenditure could be attributed to the use of novel, expensive drugs. The total costs of drugs increased on average by 8% per year during the period 1996-2000. The contribution of novel, expensive drugs nearly doubled during this period, and anticancer drugs were the most significant factor in this. A large proportion of the potentially new drugs were innovative anticancer drugs and drugs used to treat immune diseases. These compounds are likely to be expensive. Based on these findings it is expected that over the next few years, drug expenditure within hospitals to grow by at least 20% per year.
