Multiple strategies for quality improvement and patient safety--money alone is not the answer, nor is trust. Conclusions of the 6th EQuiP Invitational Conference April 2011

On 7-9 April 2011 the 6th EQuiP Invitational Conference took place in Copenhagen. Key note lectures were delivered by Professor Frede Olesen (Denmark), Professor Andreas Christian Soennichsen (Austria), Professor Martin Roland (UK) and Professor Richard Roberts (US), and a key note panel discussion was held on the pros and cons of pay-for-performance led by Doctors Iona Heath (UK) and José Braspenning (The Netherlands). In addition, there were 9 workshops and 23 oral presentations. Videos of many presentations as well as PowerPoint and other materials can be found at EQuiP's website: http://www.equip.ch .

L1₀ FePtCu bit patterned media

Chemically ordered 5 nm-thick L1₀ FePtCu films with strong perpendicular magnetic anisotropy were post-patterned by nanoimprint lithography into a dot array over a 3 mm-wide circumferential band on a 3 inch Si wafer. The dots with a diameter of 30 nm and a center-to-center pitch of 60 nm appear as single domain and reveal an enhanced switching field as compared to the continuous film. We demonstrate successful recording on a single track using shingled writing with a conventional hard disk drive write/read head.

Acceptance and importance of clinical pharmacists' LIMM-based recommendations

OBJECTIVE

The objective of this study was to evaluate the quality of the clinical pharmacy service in a Swedish hospital according to the Lund Integrated Medicine Management (LIMM) model, in terms of the acceptance and clinical significance of the recommendations made by clinical pharmacists.

METHOD

The clinical significance of the recommendations made by clinical pharmacists was assessed for a random sample of inpatients receiving the clinical pharmacy service in 2007. Two independent physicians retrospectively ranked the recommendations emerging from errors in the patients' current medication list and actual drug-related problems according to Hatoum, with rankings ranging between 1 (adverse significance) and 6 (extremely significant).

RESULTS

The random sample comprised 132 patients (out of 800 receiving the service). The clinical significance of 197 recommendations was assessed. The physicians accepted and implemented 178 (90%) of the clinical pharmacists' recommendations. Most of these recommendations, 170 (83%), were ranked 3 (somewhat significant) or higher.

CONCLUSION

This study provides further evidence of the quality of the LIMM model and confirms that the inclusion of clinical pharmacists in a multi-professional team can improve drug therapy for inpatients. The very high level of acceptance by the physicians of the pharmacists' recommendations further demonstrates the effectiveness of the process.

Impact of the Lund Integrated Medicines Management (LIMM) model on medication appropriateness and drug-related hospital revisits

PURPOSE

To examine the impact of systematic medication reconciliations upon hospital admission and of a medication review while in hospital on the number of inappropriate medications and unscheduled drug-related hospital revisits in elderly patients.

METHODS

This was a prospective, controlled study in 210 patients, aged 65 years or older, who were admitted to one of three internal medicine wards at a University Hospital in Sweden. Intervention patients received the complete Lund Integrated Medicines Management model (medication reconciliation upon admission and discharge, and medication review and monitoring) provided by a multi-professional team, including a clinical pharmacist. Control patients received standard care and medication reconciliation upon discharge. Blinded reviewers evaluated the appropriateness of the prescribing (using the Medication Appropriateness Index) on admission and discharge, and assessed the probability that a drug-related problem was the reason for any patient readmitted to hospital or visiting the emergency department within 3 months of discharge (using World Health Organisation causality criteria).

RESULTS

There was a greater decrease in the number of inappropriate drugs in the intervention group than in the control group for both the intention-to-treat population {51% [95% confidence interval (CI) 43-58%] vs. 39% (95% CI 30-48%); p = 0.0446} and the per-protocol population [60% (95% CI 51-67%) vs. 44% (95% CI 34-52%); p = 0.0106)]. There were six revisits to hospital in the intervention group which were judged as 'possibly, probably or certainly drug-related', compared with 12 in the control group (p = 0.0469).

CONCLUSIONS

In this study, medication reconciliation and review provided by a clinical pharmacist in a multi-professional team significantly reduced the number of inappropriate drugs and unscheduled drug-related hospital revisits among elderly patients.

Pharmacokinetics of thalidomide in patients with impaired renal function and while on and off dialysis

There is a renewed interest in thalidomide for use in malignancies and systemic inflammatory diseases. Reduced renal function is not uncommon among patients with these disease states but the pharmacokinetics has not been fully investigated. The aim of this study was to investigate the pharmacokinetics of thalidomide in haemodialysis patients while on and off dialysis and in myeloma patients with varying degrees of renal function.

Two studies were performed. To establish the pharmacokinetics of thalidomide in patients with mild to moderate renal failure, blood samples were taken over 12 weeks from 40 patients with multiple myeloma. A second study was performed in six patients with end-stage renal disease both on a non-dialysis day and before and during a haemodialysis session. Thalidomide concentration was determined by HPLC. A one-compartment open model with first-order absorption and elimination was used to fit total thalidomide concentration to population pharmacokinetics and statistical models using the NONMEM program. Clearance and volumes were slightly below 10 L h−1 and 1 L kg−1, respectively, in both patient groups. The inter- and intra-patient variability was low. Clearance was doubled during dialysis. There was no correlation between thalidomide clearance and renal function. In conclusion, the pharmacokinetics of thalidomide in patients with renal failure are very similar to values reported by others for patients with normal renal function. Although clearance during dialysis is doubled, thalidomide dose need not be changed for patients with decreased kidney function. There is also no need for a supplementary dose due to haemodialysis.

A multi-intervention approach on drug therapy can lead to a more appropriate drug use in the elderly. LIMM-Landskrona Integrated Medicines Management

RATIONALE, AIMS AND OBJECTIVES

To evaluate if an integrated medicines management can lead to a more appropriate drug use in elderly inpatients.

METHOD

The study was an intervention study at a department of internal medicine in southern Sweden. During the intervention period pharmacists took part in the daily work at the wards. Systematic interventions aiming to identify, solve and prevent drug-related problems (DRPs) were performed during the patient's hospital stay by multidisciplinary teams consisting of physicians, nurses and pharmacists. DRPs identified by the pharmacist were put forward to the care team and discussed. Medication Appropriateness Index (MAI) was used to evaluate the appropriateness in the patients' drug treatment at admission, discharge and 2 weeks after discharge. In total 43 patients were included, 28 patients in the intervention group and 25 patients in the group which was used as control.

RESULTS

For the intervention group there was a significant decrease in the number of inappropriate drugs compared with the control group (P = 0.049). Indication, duration and expenses were the MAI-dimensions with most inappropriate ratings, and the drugs with most inappropriate ratings were anxiolytics, hypnotics and sedatives.

CONCLUSION

This kind of systematic approach on drug therapy can result in a more appropriate drug use in the elderly.

A structured questionnaire to assess patient compliance and beliefs about medicines taking into account the ordered categorical structure of data

RATIONALE, AIMS AND OBJECTIVE

The objectives were to describe and evaluate the structured medication questionnaire and to improve data handling of results from the Morisky four-item scale for patient compliance and Beliefs about Medicines Questionnaire-specific (BMQ-specific).

METHODS

A questionnaire was developed with the purpose of being used when identifying medication errors and assessing patient compliance to and beliefs about medicines.

RESULTS

A majority of the respondents (62%; CI 45-77%) had at least one medication error. Assuming that all items are equally important in the Morisky four-item scale we presented four alternative ways to create a unidimensional global scale. A two-dimensional global scale was also constructed. The results from the BMQ-specific were presented in different ways, all taking into account that the scale has ordered verbal categories: at the level addressing each specific question, at the sub-scales 'concern' and 'necessity' level and at the global level.

CONCLUSIONS

The structured medication questionnaire can be used in daily practice as a tool to identify drug-related problems. The choice of how to use and present data from those scales in research depends on patient characteristics and how discriminating one would like the scales to be.

Medication report reduces number of medication errors when elderly patients are discharged from hospital

OBJECTIVE

To investigate whether a Medication Report can reduce the number of medication errors when elderly patients are discharged from hospital.

METHOD

We conducted a prospective intervention with retrospective controls on patients at three departments at Lund University Hospital, Sweden that where transferred to primary care. The intervention group, where patients received a Medication Report at discharge, was compared with a control group with patients of the same age, who were not given a Medication Report when discharged from the same ward one year earlier.

MAIN OUTCOME MEASURES

The main outcome measure was the number of medication errors when elderly patients were discharged from hospital.

RESULTS

Among 248 patients in the intervention group 79 (32%) had at least one medication error as compared with 118 (66%) among the 179 patients in the control group. In the intervention group 15% of the patients had errors that were considered to have moderate or high risk of clinical consequences compared with 32% in the control group. The differences were statistically significant (P<0.001).

CONCLUSION

Medication errors are common when elderly patients are discharged from hospital. The Medication Report is a simple tool that reduces the number of medication errors.

TIARA: treatment initiatives after radiological accidents

This paper describes the objectives, and reviews the progress, of the European project 'Treatment Initiatives After Radiological Accidents' (TIARA). TIARA forms part of the 'Preparatory Action for Security Research' (PASR) launched by the European Commission in 2004. The Preparatory Action is intended to reach preliminary conclusions on the needs for the security of EU citizens. It prepared a comprehensive Security Research Programme as part of the Commission's Seventh Framework Programme proposal, which was adopted in 2006 and launched in 2007. The principal purpose of TIARA is to constitute a European network that will participate in facilitating the management of a crisis in the event of the malevolent dispersal of radionuclides into the public environment.

Retinal function and histopathology in rabbits treated with Topiramate

PURPOSE

To evaluate retinal function and histopathology in rabbits treated orally with the anti-epileptic drug topiramate.

METHODS

Six rabbits were treated with a daily oral dose of topiramate during a period of eight months. Six rabbits receiving water served as controls. Blood samples were analyzed for determination of topiramate serum levels in order to ensure successful drug exposition. Standardized full-field electroretinograms (ERGs) were performed before treatment and then at 2, 3 and 8 months during the treatment period. After terminating treatment the rabbits were sacrificed and the morphology of the sectioned retina was studied.

RESULTS

After eight months of treatment the full-field ERG demonstrated normal rod function in treated and control rabbits, but the light adapted 30 Hz flicker b-wave amplitude was significantly reduced in the treated rabbits. This was the case for both the light adapted (Wilcoxon signed ranks test, P = 0.046) and the dark adapted (Wilcoxon signed ranks test, P = 0.028) 30 Hz flicker response from the treated rabbits. Retinal immunohistology revealed a severe accumulation of GABA in amacrine cells and in the inner plexiform layer in 4 of 6 treated rabbits compared to the controls.

CONCLUSIONS

Topiramate, orally administrated to rabbits, may cause a significant reduction of the retinal function demonstrated by the reduced b-wave amplitude in the full-field ERG, as well as changes in immunohistology characterized by a severe accumulation of GABA in the inner retina. The retinal dysfunction and the morphological changes indicate that topiramat may damage the retina, similarly to vigabatrin (another anti-epileptic drug).

Effects of educational outreach visits on prescribing of benzodiazepines and antipsychotic drugs to elderly patients in primary health care in southern Sweden

BACKGROUND

Different methods have previously been tested to affect GPs' prescribing habits. Attention has been drawn to benzodiazepines and antipsychotic drugs that are associated with several adverse effects in the elderly.

OBJECTIVE

To evaluate if educational outreach visits to GP practices can affect the prescribing of benzodiazepines and antipsychotic drugs to the elderly and to evaluate the opinions of the participating GPs on such education.

METHODS

In the county of Skåne, Sweden, 41 GP practices were invited to participate in educational outreach visits. Fifteen GP practices accepted the invitation. Practices were randomised to active (8 practices, 23 physicians) and control group (7 practices, 31 physicians). After the educational outreach visits prescribing of benzodiazepines and antipsychotic drugs to patients 65 years or older were measured for 1 year. The control group participated in the education after the study period. The opinions of GPs on educational outreach visits were evaluated.

RESULTS

One year after the educational outreach visits there were significant decreases in the active group compared to control group in the prescribing of medium- and long-acting benzodiazepines and total benzodiazepines but not so for antipsychotic drugs.

CONCLUSIONS

Educational outreach visits can be effective in modifying GPs' prescribing habits. We have shown this to be so for prescribing of benzodiazepines to elderly patients in primary health care. Educational outreach visits are also very well appreciated by participating GPs.
