Multilevel analysis of the influence of patients' and general practitioners' characteristics on patented versus multiple-sourced statin prescribing in France

General practitioners' compliance with benzodiazepine discontinuation guidelines in patients treated with long-term lorazepam: A case-vignette cross-sectional survey

AIM

To study determinants associated with GPs' compliance with benzodiazepine discontinuation guidelines through a case-vignette of a patient with multimorbidity treated with long-term lorazepam for insomnia.

METHODS

This cross-sectional survey was performed in a sample of French GPs. The questionnaire included items on their characteristics and questions related to the management of a case-vignette with long-term lorazepam use consulting for a prescription renewal. GPs who proposed a dedicated consultation to discuss discontinuation or progressive discontinuation were considered as "following guidelines", while they were considered as "out-of-guidelines" if they proposed immediate discontinuation or decided not to discontinue lorazepam. A backward selection process was used to select factors to be included in the final logistic regression model. The probabilities of out-of-guidelines practice and their 95% confidence interval (95% CI) were then plotted using a heatmap graph.

RESULTS

Of 1,177 GPs, the majority (92.2%) were aware of the necessity to discontinue lorazepam and reported practice consistent with good practice guidelines. Women GPs aged under 50 years had the lowest estimated probability of out-of-guidelines practice. Conversely, men aged over 58 years with high consideration of patient preferences and low concern about the benefit-risk ratio of lorazepam had the highest probability of out-of-guidelines practice (27.3% [18.7%; 34.7%]).

CONCLUSION

GPs largely reported practice compliant with benzodiazepine discontinuation guidelines, although some GPs, mainly older men who overemphasise patient preferences, were more likely to adopt out-of-guidelines practice.

Group practice impacts on patients, physicians and healthcare systems: a scoping review

OBJECTIVE

To identify the advantages and disadvantages that group practices have on patients, physicians and healthcare systems.

STUDY DESIGN

A scoping review was performed based on the methodology proposed by Arksey and O'Malley, and refined by Levac et al. Titles and abstracts were screened by two reviewers. A quantitative analysis was performed to assess the type, year and region of publication, as well as the population studied. A qualitative descriptive analysis was performed to identify common themes.

STUDY SETTING

MEDLINE, EMBASE and Cochrane databases were searched from database inception to October 2018 for papers which assessed outcomes relevant to the research question.

RESULTS

Our search strategy returned 2408 papers and 98 were included in the final analysis. Most papers were from the USA, were surveys and assessed physician outcomes. Advantages of group practices for patients included improved satisfaction and quality of care. Studies of physicians reported improved quality of life and income, while disadvantages included increased stress due to poor interpersonal relationships. Studies of healthcare systems reported improved efficiency and better utilisation of resources.

CONCLUSIONS

Group practices have many benefits for patients and physicians. However, further work needs to be done assessing patient outcomes and establishing the elements that make a group practice successful.

Exploring knowledge and perceptions on generic drugs of final year pharmacy school students in Greece

Objectives: The economic crisis in Greece has triggered an extensive public debate about the use of generic drugs (generics). Despite their cost-saving potential, generic market penetration remains very low. This raises questions on awareness of, perception on and preference for generics by health-care professionals and patients. This is a descriptive study on the level of knowledge and attitudes towards generics of final year pharmacy school students in Greece. Methods: An electronic questionnaire was distributed to 173 senior pharmacy school students in three Universities in Greece. Responses were submitted electronically. Results: The majority of students knew that generics contain the same active ingredient as the originator products and are cheaper. Students were somehow concerned with safety and efficacy of generics. The majority of students agreed that pharmacists should probably recommend the use of generics, and indicated that prescribing and dispensing practices would largely depend on the profit margin. Despite more than half of the students expressing a positive attitude towards generics, they were inadequately educated on their features. Conclusion: It is critical to improve knowledge of and preference for generics amongst health-care professionals from early on if to build the trust required to increase generic market penetration and achieve measurable savings in pharmaceutical expenditure.

Perceptions of pharmacists and physicians on generic substitution in a financial crisis context in Northwestern Spain: A qualitative study

In Spain, the use of generics has considerably evolved in a short period of time through different anti-crisis legislation changes. Before the financial crisis the proposal of generics was an option for patients. Nowadays its use is actively enforced by Health authorities.

OBJECTIVE

To explore the perceptions of pharmacists and physicians regarding the generic substitution driven by new Spanish drugs policies as well as their adaptive strategies intended to lessen the impact of changes to their patients' treatment.

METHODS

Pharmacists (16) and physicians (13) from Ferrol and A Coruña participated in a qualitative study using semi-structured in-depth interviews.

RESULTS

Qualitative analysis allowed identification of nine key components in the substitution process: Enabling factors: 'Adequate information to patients', 'Acute treatments', 'Bioappearance', 'Prescription by Estate Official Denomination followed by laboratory name', 'Personalized dosage systems'. Obstructing factors: 'Generics/Authorities distrust', 'Lack of time', 'Patient characteristics', 'Pharmacy financial management'.

CONCLUSIONS

Pharmacists and physicians in our economic crisis context perceive different barriers resulting in difficulties in the generic substitution process. They have implemented strategies to capitalize on the enablers and overcome the additional budget-cut barriers imposed by the Administration that had prevented them from maintaining their patient's treatment preferences. Spanish health authorities could improve current legislation either by reducing the number of new laboratories of authorized generic manufacturers or by extending the pharmacist capability for equivalent drugs substitution.

[Evolution, determinants and regulation of drug expenditures in France]

According to the Organization for Economic Co-operation and Development (OECD), drug expenditures account for about 20 % of all health expenditures in high-income countries. The increase of these drug expenditures which has been observed in all these countries over a long period is due to the combination of aging populations, changes in medical practices and the dynamics of the pharmaceutical market, in particular the hospital market. France is no exception. Its consumption of drugs (which accounted for 17.5 % of health expenditures in 2014), historically among the highest in volume, has grown slower in the last decade than in other OECD countries. However, the particularly rapid and wide adoption of pharmaceutical innovations, which has always characterized France, has had in recent years a very significant effect on the soaring drug expenditures covered by the social protection system (plus 1.1 billion in 2014, a year marked by the introduction of new therapies against hepatitis C). This significant effect should continue with the introduction of new and very expensive therapies, particularly in oncology.

Price and utilisation differences for statins between four countries

INTRODUCTION

Australia, England, France and New Zealand use different policies to regulate their medicines market, which can impact on utilisation and price.

OBJECTIVES

To compare the prices and utilisation of statins in Australia, England, France and New Zealand from 2011 to 2013.

METHODS

Utilisation of statins in the four countries was compared using Defined Daily Doses (DDD) per 1000 inhabitants per year. Pairwise Laspeyres and Paasche index comparisons were conducted comparing the price and utilisation of statins.

RESULTS

The results showed that the price of statins in New Zealand was the cheapest. The price of statins in Australia was most expensive in 2011 and 2012 but France was more expensive in 2013. There were large differences between the Laspeyres index and Paasche index when comparing the price and utilisation of England with Australia and France.

DISCUSSION

The policies that regulate the New Zealand and England medicines markets were more effective in reducing the price of expensive statins. The relative utilisation of cheaper statins was greatest in England and had a large effect on the differences between the two index results. The pricing policies in Australia have been only partly effective in reducing the price of statins compared to other countries.

Trends in Statin Use in Seniors 1999 to 2013: Time Series Analysis

PURPOSE

To examine HMG-CoA reductase inhibitor (statin) drug dispensing patterns to Nova Scotia Seniors' Pharmacare program (NSSPP) beneficiaries over a 14-year period in response to: 1) rosuvastatin market entry in 2003, 2) JUPITER trial publication in 2008, and 3) generic atorvastatin availability in 2010.

METHODS

All NSSPP beneficiaries who redeemed at least one prescription for a statin from April 1, 1999 to March 31, 2013 were included. Aggregated, anonymous monthly prescription counts were extracted by the Nova Scotia Department of Health and Wellness (Nova Scotia, Canada) and changes in dispensing patterns of statins were measured. Data were analyzed using descriptive analyses and interrupted time series methods.

RESULTS

The percentage of NSSPP beneficiaries dispensed any statin increased from 5.3% in April 1999 to 20.7% in March 2013. In 1999, most NSSPP beneficiaries were dispensed either simvastatin (29.5%) or atorvastatin (28.7%). When rosuvastatin was added to the NSSPP Formulary in August 2003, prescriptions dispensed for simvastatin, lovastatin, pravastatin, and fluvastatin declined significantly (slope change, -0.0027; 95% confidence interval (CI), (-0.0046, -0.0009)). This significant decline continued following the publication of JUPITER (level change, -0.1974; 95% CI, (-0.2991, -0.0957)) and the availability of generic atorvastatin (level change, -0.2436; 95% CI, (-0.3314, -0.1558)). Atorvastatin was not significantly affected by any of the three interventions, although it maintained an overall decreasing trend. Only upon the availability of generic atorvastatin did the upward trend in rosuvastatin use decrease significantly (slope change, -0.0010, 95% CI, (-0.0015, -0.0005)).

CONCLUSIONS

The type and rate of statins dispensed to NSSPP beneficiaries changed from 1999 to 2013 in response to the availability of new agents and publication of the JUPITER trial. The overall proportion of NSSPP beneficiaries dispensed a statin increased approximately 4-fold during the study period. In 2013, rosuvastatin was the most commonly dispensed statin (44.1%) followed by atorvastatin (39.1%).

Disinvestment and Value-Based Purchasing Strategies for Pharmaceuticals: An International Review

Pharmaceutical expenditure has increased rapidly across many Organisation for Economic Cooperation and Development (OECD) countries over the past three decades. This growth is an increasing concern for governments and other third-party payers seeking to provide equitable and comprehensive healthcare within sustainable budgets. In order to create headroom for increasing utilisation, and to fund new high-cost therapies, there is an active push to 'disinvest' from low-value drugs. The aim of this article is to review how reimbursement policy decision makers have sought to partially or completely disinvest from drugs in a range of OECD countries (UK, France, Canada, Australia and New Zealand) where they are publicly funded or subsidised. We employed a systematic literature search strategy and the incorporation of grey literature known to the authorship team. We canvass key policy instruments from each country to outline key approaches to the identification of candidate drugs for disinvestment assessment (passive approaches vs. more active approaches); methods of disinvestment and value-based purchasing (de-listing, restricting treatment, price or reimbursement rate reductions, encouraging generic prescribing); lessons learnt from the various approaches; the potential role of coverage with evidence development; and the need for careful stakeholder management. Dedicated sections are provided with detailed coverage of policy approaches (with drug examples) from each country. Historically, countries have relied on 'passive disinvestment'; however, due to (1) the availability of new cost-effectiveness evidence, or (2) 'leakage' in drug utilisation, or (3) market failure in terms of price competition, there is an increasing focus towards 'active disinvestment'. Isolating low-value drugs that would create headroom for innovative new products to enter the market is also motivating disinvestment efforts by multiple parties, including industry. Historically, disinvestment has mainly taken the form of price reductions, especially when market failures are perceived to exist, and restricting treatment to subpopulations, particularly when a drug is no longer considered value for money. There is considerable experimentation internationally in mechanisms for disinvestment and the opportunity for countries to learn from each other. Ongoing evaluation of disinvestment strategies is essential, and ought to be reported in the peer-reviewed literature.

Quality and efficiency of statin prescribing across countries with a special focus on South Africa: findings and future implications

INTRODUCTION

Statins are recommended first-line treatment for hyperlipidemia, with published studies suggesting limited differences between them. However, there are reports of under-dosing. South Africa has introduced measures to enhance generic utilization. Part one documents prescribed doses of statins in 2011. Part two determines the extent of generics versus originator and single-sourced statins in 2011 and their costs.

RESULTS

Underdosing of simvastatin in 2011 with average prescribed dose of 23.7 mg; however, not for atorvastatin (20.91 mg) or rosuvastatin (15.02 mg). High utilization of generics versus originators at 93-99% for atorvastatin and simvastatin, with limited utilization of single-sourced statins (22% of total statins - defined daily dose basis), mirroring Netherlands, Sweden and UK. Generics priced 33-51% below originator prices.

DISCUSSION

Opportunity to increase simvastatin dosing through education, prescribing targets and incentives. Opportunity to lower generic prices with generic simvastatin 96-98% below single-sourced prices in some European countries.

Analysis of French generic medicines retail market: why the use of generic medicines is limited

The market share of generic medicines in France is low compared to other European countries. This perspective paper provides an overview of the generic medicines retail market in France and how the current policy environment may affect the long-term sustainability. Looking at the French generic medicines retail market and the surrounding regulatory framework, all conditions seem to be in place to create a healthy generic medicines market: the country has well-respected regulatory authorities, generic medicines enter the market in a timely manner and prices of generic medicines are competitive compared with other European countries. Despite the success of the demand-side policies targeted at pharmacists and patients, those targeted at physicians were less successful due to a lack of enforcement and a lack of trust in generic medicines by French physicians. Recommendations to increase the use of generic medicines in France round off this perspective paper.

Compliance with quality prescribing indicators linked to financial incentives: what about not incentivized indicators?: an observational study

OBJECTIVE

The aims of this study were to investigate whether general practitioners (GPs) who complied with quality prescribing indicators included in the pay-for-performance programmes also complied with quality prescribing indicators which are not linked to incentives and to compare the prescribing behaviour between those GPs who showed compliance with quality prescribing indicators linked to financial incentives and those who did not.

DESIGN AND METHODOLOGY

This was a descriptive cross-sectional study which was conducted in 2007 in the Aljarafe Primary Care Area (Andalusia, Spain) and involved 37 Health Care Centres and 176 GPs. The main outcome was the results of a comparison of six quality prescribing indicators linked to incentives and 14 quality prescribing indicators not linked to incentives. The chi-square test was used to compare qualitative variables. Quantitative variables were tested using Student's t test upon confirmation of normality.

RESULTS

Those GPs showing compliance with the indicators included in the pay-for performance programme showed low levels of compliance with quality prescribing indicators that were unincentivised. With respect to compliance with the indicators not linked to financial incentives, we found no statistical difference between GPs who showed compliance with incentivised indicators (n = 57) and those showing non-compliance (n = 112) in terms of drug selection, with the exception of the selection of second- and third-line antibiotics and antihistamines, nor in terms of the appropriate use of drugs linked to patient's clinical conditions.

CONCLUSIONS

The compliance of GPs showing compliance with quality prescribing indicators included in pay-for-performance programmes was not better than that of those who showed no compliance with other relevant quality prescribing indicators not linked to financial incentives.
