Do clinical practice education groups result in sustained change in GP prescribing?

Deprescribing Anticholinergic and Sedative Drugs to Reduce Polypharmacy in Frail Older Adults Living in the Community: A Randomized Controlled Trial

BACKGROUND

Polypharmacy is associated with poor outcomes in older adults. Targeted deprescribing of anticholinergic and sedative medications may improve health outcomes for frail older adults. Our pharmacist-led deprescribing intervention was a pragmatic 2-arm randomized controlled trial stratified by frailty. We compared usual care (control) with the intervention of pharmacists providing deprescribing recommendations to general practitioners.

METHODS

Community-based older adults (≥65 years) from 2 New Zealand district health boards were recruited following a standardized interRAI needs assessment. The Drug Burden Index (DBI) was used to quantify the use of sedative and anticholinergic medications for each participant. The trial was stratified into low, medium, and high-frailty. We hypothesized that the intervention would increase the proportion of participants with a reduction in DBI ≥ 0.5 within 6 months.

RESULTS

Of 363 participants, 21 (12.7%) in the control group and 21 (12.2%) in the intervention group had a reduction in DBI ≥ 0.5. The difference in the proportion of -0.4% (95% confidence interval [CI]: -7.9% to 7.0%) provided no evidence of efficacy for the intervention. Similarly, there was no evidence to suggest the effectiveness of this intervention for participants of any frailty level.

CONCLUSION

Our pharmacist-led medication review of frail older participants did not reduce the anticholinergic/sedative load within 6 months. Coronavirus disease 2019 (COVID-19) lockdown measures required modification of the intervention. Subgroup analyses pre- and post-lockdown showed no impact on outcomes. Reviewing this and other deprescribing trials through the lens of implementation science may aid an understanding of the contextual determinants preventing or enabling successful deprescribing implementation strategies.

Factors Associated with Underreporting of Adverse Drug Reactions by Health Care Professionals: A Systematic Review Update

INTRODUCTION

Underreporting is a major limitation of the voluntary reporting system of adverse drug reactions (ADRs). A 2009 systematic review showed the knowledge and attitudes of health professionals were strongly related with underreporting of ADRs.

OBJECTIVE

Our aim was to update our previous systematic review to determine factors (sociodemographic, knowledge and attitudes) associated with the underreporting of ADRs by healthcare professionals.

METHODS

We searched the MEDLINE and EMBASE databases for studies published between 2007 and 2021 that met the following inclusion criteria: (1) published in English, French, Portuguese or Spanish; (2) involving health professionals; and (3) the goal was to evaluate factors associated with underreporting of ADRs through spontaneous reporting.

RESULTS

Overall, 65 papers were included. While health professional sociodemographic characteristics did not influence underreporting, knowledge and attitudes continue to show a significant effect: (1) ignorance (only serious ADRs need to be reported) in 86.2%; (2) lethargy (procrastination, lack of interest, and other excuses) in 84.6%; (3) complacency (the belief that only well tolerated drugs are allowed on the market) in 46.2%; (4) diffidence (fear of appearing ridiculous for reporting merely suspected ADRs) in 44.6%; and (5) insecurity (it is nearly impossible to determine whether or not a drug is responsible for a specific adverse reaction) in 33.8%, and the absence of feedback in 9.2%. In this review, the non-obligation to reporting and confidentiality emerge as new reasons for underreporting.

CONCLUSIONS

Attitudes regarding the reporting of adverse reactions continue to be the main determinants of underreporting. Even though these are potentially modifiable factors through educational interventions, minimal changes have been observed since 2009.

Implementing an Online Program to Change Benzodiazepine Prescription: Protocol of a Hybrid Type 1 Cluster-Randomised Trial

Introduction

Excessive benzodiazepine (BZD) prescription has long been considered a serious mental health concern in many countries. Many interventions using different methodologies have been implemented to change BZD prescription patterns in primary health care settings, with limited positive results.

Objectives

The primary objective of our study was to analyse the effectiveness and implementation process of an intervention aimed at changing BZD prescription patterns in a primary health care setting in Portugal.

Methodology

We chose as methodology an effectiveness-implementation hybrid type 1 intervention. Our intervention was based on the development of an online platform, named ePrimaPrescribe, which was delivered using a Digital Behaviour Change Intervention (DBCI), using a two-arm cluster-randomised clinical trial.

Results

We primarily aimed to evaluate the effectiveness of our DBCI in changing BZD prescription patterns using the frequency of BZD prescriptions issued per month as an outcome measure. Secondarily, we aimed to analyse the effect of ePrimaPrescribe on antidepressant prescriptions, to study the effect of the platform on diagnosis registration associated with BZDs and antidepressant prescription, and to perform a cost analysis considering the monthly National Health Service spending on BZD co-payments. Finally, we aimed to analyse the implementation process using quantitative and qualitative methods.

Conclusion

With this study, we expect to contribute with a cost-effective intervention to change the complex matter of excessive BZD prescriptions, and also to improve insight into the challenges to intervention implementation processes in primary health care settings. We believe that our findings are relevant not only to the specific setting where the study was implemented, but also to all countries where primary health care plays a central role in care provision.

Staying 'Covid-safe': Proposals for embedding behaviours that protect against Covid-19 transmission in the UK

OBJECTIVES

The Scientific Pandemic Insights group on Behaviours (SPI-B) as part of England's Scientific Advisory Group on Emergencies (SAGE), were commissioned by the UK Cabinet Office to identify strategies to embed infection control behaviours to minimize Covid-19 transmission in the long term.

METHODS

With minimal direct evidence available, three sources of information were used to develop a set of proposals: (1) a scoping review of literature on sustaining behaviour change, (2) a review of key principles used in risk and safety management, and (3) prior reports and reviews on behaviour change from SPI-B. The information was collated and refined through discussion with SPI-B and SAGE colleagues to finalize the proposals.

RESULTS

Embedding infection control behaviours in the long-term will require changes to the financial, social, and physical infrastructure so that people in all sections of society have the capability, opportunity, and motivation needed to underpin those behaviours. This will involve building Covid-safe educational programmes, regulating to ensure minimum standards of safety in public spaces and workspaces, using communications and social marketing to develop a Covid-safe culture and identity, and providing resources so that all sections of society can build Covid-safe behaviours into their daily lives.

CONCLUSIONS

Embedding 'Covid-safe' behaviours into people's everyday routines will require a co-ordinated programme to shape the financial, physical, and social infrastructure in the United Kingdom. Education, regulation, communications, and social marketing, and provision of resources will be required to ensure that all sections of society have the capability, opportunity, and motivation to enact the behaviours long term.

Staying 'Covid-safe': Proposals for embedding behaviours that protect against Covid-19 transmission in the UK

Objectives

The Scientific Pandemic Insights group on Behaviours (SPI‐B) as part of England’s Scientific Advisory Group on Emergencies (SAGE), were commissioned by the UK Cabinet Office to identify strategies to embed infection control behaviours to minimize Covid‐19 transmission in the long term.

With minimal direct evidence available, three sources of information were used to develop a set of proposals: (1) a scoping review of literature on sustaining behaviour change, (2) a review of key principles used in risk and safety management, and (3) prior reports and reviews on behaviour change from SPI‐B. The information was collated and refined through discussion with SPI‐B and SAGE colleagues to finalize the proposals.

Results

Embedding infection control behaviours in the long‐term will require changes to the financial, social, and physical infrastructure so that people in all sections of society have the capability, opportunity, and motivation needed to underpin those behaviours. This will involve building Covid‐safe educational programmes, regulating to ensure minimum standards of safety in public spaces and workspaces, using communications and social marketing to develop a Covid‐safe culture and identity, and providing resources so that all sections of society can build Covid‐safe behaviours into their daily lives.

Conclusions

Embedding ‘Covid‐safe’ behaviours into people’s everyday routines will require a co‐ordinated programme to shape the financial, physical, and social infrastructure in the United Kingdom. Education, regulation, communications, and social marketing, and provision of resources will be required to ensure that all sections of society have the capability, opportunity, and motivation to enact the behaviours long term.

Hospital avoidance: an integrated community system to reduce acute hospital demand

Background:

Growth in emergency department (ED) attendance and acute medical admissions has been managed to very low rates for 18 years in Canterbury, New Zealand, using a combination of community and hospital avoidance strategies. This paper describes the specific strategies that supported management of acutely unwell patients in the community as part of a programme to integrate health services.

Intervention:

Community-based acute care was established by a culture of close collaboration and trust between all sectors of the health system, with general practice closely involved in the design and management of the services, and support provided by hospital specialists, coordination and diagnostic units, and competent informatics. Introduction of the community-based services was aided by a clinical guidance website and an education programme for general practice teams and allied health professionals.

Outcomes:

Attendance at EDs and acute medical admission rates have been held at low growth and, in some cases, shorter lengths of hospital stay. This trend was especially evident in elderly patients and those with ambulatory care sensitive or chronic disorders.

Conclusions:

A system of community-based care and education has resulted in sustained gains for the Canterbury health system and freed-up hospital resources. This outcome has engendered a sense of empowerment for general practice teams and their patients.

Quality circles for quality improvement in primary health care: Their origins, spread, effectiveness and lacunae- A scoping review

Quality circles or peer review groups, and similar structured small groups of 6–12 health care professionals meet regularly across Europe to reflect on and improve their standard practice. There is debate over their effectiveness in primary health care, especially over their potential to change practitioners’ behaviour. Despite their popularity, we could not identify broad surveys of the literature on quality circles in a primary care context. Our scoping review was intended to identify possible definitions of quality circles, their origins, and reported effectiveness in primary health care, and to identify gaps in our knowledge. We searched appropriate databases and included any relevant paper on quality circles published until December 2017. We then compared information we found in the articles to that we found in books and on websites. Our search returned 7824 citations, from which we identified 82 background papers and 58 papers about quality circles. We found that they originated in manufacturing industry and that many countries adopted them for primary health care to continuously improve medical education, professional development, and quality of care. Quality circles are not standardized and their techniques are complex. We identified 19 papers that described individual studies, one paper that summarized 3 studies, and 1 systematic review that suggested that quality circles can effectively change behaviour, though effect sizes varied, depending on topic and context. Studies also suggested participation may affirm self-esteem and increase professional confidence. Because reports of the effect of quality circles on behaviour are variable, we recommend theory-driven research approaches to analyse and improve the effectiveness of this complex intervention.

Safer Prescribing and Care for the Elderly (SPACE): Protocol of a Cluster Randomized Controlled Trial in Primary Care

BACKGROUND

High-risk prescribing, adverse drug events, and avoidable adverse drug event hospitalizations are common. The single greatest risk factor for high-risk prescribing and adverse drug events is the number of medications a person is taking. More people are living longer and taking more medications for multiple long-term conditions. Most on-going prescribing occurs in primary care. The most effective, cost-effective, and practical approach to safer prescribing in primary care is not yet known.

OBJECTIVE

To test the effect of the Safer Prescribing And Care for the Elderly (SPACE) intervention on high-risk prescribing of nonsteroidal anti-inflammatory and antiplatelet medicines, and related adverse drug event hospitalizations.

METHODS

This is a protocol of a cluster randomized controlled trial. The clusters will be primary care practices. Data collection and analysis will be at the level of patient.

RESULTS

Recruitment started in 2018. Six-month data collection will be in 2018.

CONCLUSIONS

This study addresses an important translational gap, testing an intervention designed to prompt medicines review and support safer prescribing in routine primary care practice.

Does educational intervention improve doctors' knowledge and perceptions of generic medicines and their generic prescribing rate? A study from Malaysia

Objectives:

To investigate the impact of an educational intervention on doctors’ knowledge and perceptions towards generic medicines and their generic (international non-proprietary name) prescribing practice.

Methods:

This is a single-cohort pre-/post-intervention pilot study. The study was conducted in a tertiary care hospital in Perak, Malaysia. All doctors from the internal medicine department were invited to participate in the educational intervention. The intervention consisted of an interactive lecture, an educational booklet and a drug list. Doctors’ knowledge and perceptions were assessed by using a validated questionnaire, while the international non-proprietary name prescribing practice was assessed by screening the prescription before and after the intervention.

Results:

The intervention was effective in improving doctors’ knowledge towards bioequivalence, similarity of generic medicines and safety standards required for generic medicine registration (p = 0.034, p = 0.034 and p = 0.022, respectively). In terms of perceptions towards generic medicines, no significant changes were noted (p > 0.05). Similarly, no impact on international non-proprietary name prescribing practice was observed after the intervention (p > 0.05).

Conclusion:

Doctors had inadequate knowledge and misconceptions about generic medicines before the intervention. Moreover, international non-proprietary name prescribing was not a common practice. However, the educational intervention was only effective in improving doctors’ knowledge of generic medicines.

Effects of reviewing routine practices on learning outcomes in continuing education

CONTEXT

Conventional continuing medical education (CME) has been shown to have modest effects on doctor performance. New educational approaches based on the review of routine practices have brought better results. Little is known about factors that affect the outcomes of these approaches, especially in middle-income countries. This study aimed to investigate factors that influence the learning and quality of clinical performance in CME based on reflection upon experiences.

METHODS

A questionnaire and a clinical performance test were administered to 165 general practitioners engaged in a CME programme in Brazil. The questionnaire assessed behaviours related to four input variables (individual reflection on practices, peer review of experiences, self-regulated learning and learning skills) and two mediating variables (identification of learning needs and engagement in learning activities, the latter consisting of self-study of scientific literature, consultations about patient problems, and attendance at courses). Structural equation modelling was used to test a hypothesised model of relationships between these variables and the outcome variable of clinical performance, measured by the clinical performance test.

RESULTS

After minor adjustments, the hypothesised model fit the empirical data well. Individual reflection fostered identification of learning needs, but also directly positively influenced the quality of clinical performance. Peer review did not affect identification of learning needs, but directly positively affected clinical performance. Learning skills and self-regulation did not help in identifying learning needs, but self-regulation enhanced study of the scientific literature, the learning activity that most positively influenced clinical performance. Consultation with colleagues, the activity most frequently triggered by the identification of learning needs, did not affect performance, and attendance of courses had only limited effect.

CONCLUSIONS

This study shed light on the factors that influence learning and performance improvement in continuing education based on the review of routine practices in middle-income settings. The findings support the importance of reflection on practices as an instrument for enhancing clinical performance.

Strategies to increase the sensitivity of pharmacovigilance in Portugal

OBJECTIVE

To evaluate the results of an intervention to improve the number and relevance of reports of adverse drug reactions.

METHODS

A cluster-randomized controlled trial was conducted with pharmacists working in Northern Portugal, in 2007. After randomization, 364 individuals were placed into the intervention group (261 in telephone interviews and 103 in workshops), while the control group was comprised of 1,103 pharmacists. The following were approached in the educational intervention: the problem of adverse drug reaction, the impact on public health and spontaneous reporting. With regard to relevance, adverse reactions were classified into severe and unexpected. Statistical analysis was performed, based on the intention-to-treat principle; generalized linear mixed models were applied, using the penalized quasi-likelihood method. The pharmacists studied were followed during a period of 20 months.

RESULTS

The intervention increased the rate of spontaneous reporting of adverse reactions three times (RR = 3.22; 95% CI 1.33;7.80), when compared to the control group. The relevance of reporting rose, with an increase in severe adverse reactions by approximately four times (RR = 3.87; 95% CI 1.29;11.61) and in unexpected adverse reactions by five times (RR = 5.02; 95% CI 1.33;18.93), compared to the control group.

CONCLUSIONS

During a period of up to four months, educational interventions significantly increased the number and relevance of spontaneous reporting of adverse drug reactions by pharmacists in Northern Portugal.

Translating dementia research into practice

There is a gap between the knowledge obtained in dementia research and the practical use of it. This review examines the concept of knowledge translation (KT) and the process of translating research into practice in the field of dementia. KT in dementia practice involves key players including researchers, educators, clinicians, policy-makers, the general public and consumers who act within a multidimensional network, disseminating findings widely to effect changes in community awareness, clinical practice and health policy. Challenges include the volume of dementia research; difficulties in determining who is responsible for KT; the problems of premature KT; the lack of resources to perform KT; the paucity of research about effective KT strategies; and the characteristics of the dementia care workforce. Key features of effective KT include a simple compelling message; use of interpersonal contact and roles; a practical framework with an emphasis on "know-how"; and the provision of resources and support. More effective dementia KT will require a commitment by key players to engage in the process, a better understanding of effective KT strategies, adequate resources, and judicious selection of appropriate evidence-based information.

Improving the reporting of adverse drug reactions: a cluster-randomized trial among pharmacists in Portugal

BACKGROUND

Adverse drug reaction (ADR) reporting systems are the basic component for comprehensive postmarketing surveillance of the risk of drug-induced adverse effects. The aim of this study was to evaluate the effectiveness of educational outreach visits aimed at improving ADR reporting by pharmacists.

METHODS

The study population comprised all pharmacists working in a catchment area covered by Portugal's Northern Regional Health Authority. Using unequal randomization, four spatial-clusters were assigned to the intervention group (n = 342) and eleven to the control group (n = 1091). The intervention took the form of 1-hour long educational outreach visits tailored to training needs detected in a previous study, with a 13- to 16-month follow-up period (March-June 2004 through June 2005). This study is registered as an international standard randomized controlled trial, number ISRCTN45894687.

RESULTS

At baseline, ADR reporting rates (per 1000 pharmacist-years) did not differ significantly between the intervention and control groups (32.28 vs 29.16). The adjusted increase in ADR reporting attributable to the intervention was 275.63 per 1000 pharmacist-years (95% CI 162.15, 389.12; relative risk [RR] = 5.87, 95% CI 1.98, 17.39). The intervention succeeded in multiplying the reporting rate of: serious ADRs, 10-fold (RR = 9.79; 95% CI 2.24, 42.66); unexpected ADRs, 4-fold (RR = 4.41; 95% CI 1.11, 17.53); high-causality ADRs, 9-fold (RR = 8.67; 95% CI 2.12, 35.42); and new drug-related ADRs, 9-fold (RR = 9.33; 95% CI 2.53, 34.40). While the greatest effect was registered during the first 4 months post-intervention, differences remained statistically significant for 8 months.

CONCLUSIONS

Educational outreach visits improve ADR reporting by pharmacists in terms of quantity and relevance.

Encouraging physician appropriate prescribing of non-steroidal anti-inflammatory therapies: protocol of a randomized controlled trial [ISRCTN43532635]

Background

Traditional non-steroidal anti-inflammatory drugs (NSAIDs) are a widely used class of therapy in the treatment of chronic pain and inflammation. The drugs are effective and can be relatively inexpensive thanks to available generic versions. Unfortunately the traditional NSAIDs are associated with gastrointestinal complications in a small proportion of patients, requiring costly co-therapy with gastro-protective agents. Recently, a new class of non-steroidal anti-inflammatory agents known as coxibs has become available, fashioned to be safer than the traditional NSAIDs but priced considerably higher than the traditional generics. To help physicians choose appropriately and cost-effectively from the expanded number of anti-inflammatory therapies, scientific bodies have issued clinical practice guidelines and third party payers have published restricted reimbursement policies. The objective of this study is to determine whether an educational intervention can prompt physicians to adjust their prescribing in accordance with these expert recommendations.

Methods

This is an ongoing, randomized controlled trial. All primary care physicians in Manitoba, Canada have been randomly assigned to a control group or an intervention study group. The educational intervention being evaluated consists of an audit and feedback mechanism combined with optional participation in a Continuing Medical Education interactive workshop. The primary outcome of the study is the change, from pre-to post-intervention, in physicians' appropriate prescribing of non-steroidal anti-inflammatory therapies for patients requiring chronic treatment. Three classes of non-steroidal anti-inflammatory therapies have been identified: coxib therapy, traditional NSAID monotherapy, and traditional NSAID therapy combined with gastro-protective agents. Appropriate prescribing is defined based on international clinical practice guidelines and the provincial drug reimbursement policy in Manitoba.
