Potential savings without compromising the quality of care

A six years trend analysis of systemic antibiotic consumption in Northwest Ethiopia

BACKGROUND

Consumption of antibiotics, a major global threat to public health, is perhaps the key driver of antibiotic resistance. Monitoring antibiotic consumption is crucial to tackling antimicrobial resistance. This study assessed antibiotic consumption trends during the last six years in the Bahir Dar branch of the Ethiopian pharmaceutical supply agency (EPSA), Northwest Ethiopia, in 2022.

METHODS

Retrospective data were collected in August 2022 based on antibiotic distribution data from the Bahir Dar Brach of EPSA from July 2016 to June 2022. Data were analyzed according to the Anatomic Therapeutic Classification (ATC) developed by the World Health Organization (WHO). We measured antibiotic consumption using a defined daily dose per 1000 inhabitants per day (DIDs) based on the Agency's catchment population. Descriptive statistics and trend analyses were conducted.

RESULTS

About 30.34 DIDs of antibiotics were consumed during the six years. The consumption of antibiotics decreased by 87.4%, from 6.9 DIDs in 2016/17 to 0.9 DIDs in 2021/22. Based on the WHO AWaRe classification, 23.39 DIDs (77.1%) of the consumed antibiotics were from the Access category. Consumption of Access category antibiotics was decreased by 72.7% (from 5 to 0.5 DIDs) but Watch antibiotics decreased by 54.3% (from 1.8 to 0.4 DIDs). Oral antibiotics accounted for 29.19 DIDs (96.2%) of all consumed systemic antibiotics. The average cost expenditure per DDD for all antibiotics was 54.1 birr/DDD (0.4-482.3 birr/DDD). Only seven antibiotics accounted for DU90% and the cost expenditure per DDD for the DU90% antibiotics ranged from 0.4/DDD for Doxycycline to 232.8 birr/DDD for Piperacillin/tazobactam. Overall, during the last six years, the most commonly used antibiotic was Amoxicillin (10.1 DIDs), followed by Doxycycline (5.3 DIDs) and Ciprofloxacin (3.4 DIDs).

CONCLUSION

In this study, we found that antibiotic usage was low and continuously declining over time. Minimizing unnecessary antibiotic usage is one possible approach to reduced AMR. However, a shortage of access to important medicines can compromise the quality of treatment and patient outcomes. A prospective study is needed to evaluate the balance of patient outcomes and reduce AMR by optimizing the community consumption of systemic antibiotics.

Trends in the Cost of Medicines, Consultation Fees and Clinic Visits in Malaysia's Private Primary Healthcare System: Employer Health Insurance Coverage

Objective

To examine trends in the cost of medicines, consultation fees and clinic visits among the employees covered by the employer health insurance in Malaysia's private primary healthcare system in Malaysia.

Designs

Retrospective cross-sectional study.

Setting

PMCare claims database from January 2016 to August 2019.

Participants

A total of 83,556 outpatient clinic visits involving 10,150 IIUM employees of the International Islamic University Malaysia (IIUM) to private general practitioners (GPs). During the study period, IIUM adopts the incentive structure of capping coverage at Ringgit Malaysia (RM) 45/outpatient visit (USD 10.58) to cover for consultation fees and medicine costs.

Main Outcome Measures

The monthly percentage change in the number of clinic visits, medicine costs, consultation fees and total costs between January 2016 and August 2019. A simple linear regression using Stata v15.1 was also performed to measure the association between the characteristics of the prescribed medicines and medicine charges.

Results

The number of clinic visits per patient increased by 17% from January 2016 to August 2019, with consultation fees increasing by 113.9% and total costs by 7.9% per clinic visit per patient. Conversely, the cost of medicines and the number of medicines prescribed per clinic visit per patient decreased by 39.7% and 6.3%, respectively.

Conclusion

Within the incentive structure of capping the total amount of coverage per clinic visit, medicine costs were reduced by decreasing the number of medicines prescribed, to offset the increased consultation fees. This may create perverse incentives that affect medicine use with negative consequences for the health system and health insurers.

Sources of Information on Medicinal Products Among Physicians - A Survey Conducted Among Primary Care Physicians in Poland

Introduction: Primary care physicians need to have access to up-to-date knowledge in various fields of medicine and high-quality information sources, but little is known about the use and credibility of sources of information on medicinal products among Polish doctors. The main goal of this study was to analyze the sources of information on medicinal products among primary care physicians in Poland.

Methods: A survey was conducted among 316 primary care physicians in Poland. The following information was collected: demographic data of participants, type and frequency of using data sources on medicinal products, barriers to access credible information, assessment of the credibility of the sources used, impact of a given source and other factors on prescription decisions.

Results: The most frequently mentioned sources of information were medical representatives (79%), medical journals (78%) and congresses, conventions, conferences, and training (76%). The greatest difficulty in finding the latest information about medicinal products was the lack of time. The surveyed doctors considered clinical guidelines to be the most credible source of information, and this source also had the greatest impact on the choice of prescribed medicinal products.

Conclusion: The study showed that clinicians consider clinical guidelines as the most credible source of information with the greatest impact on prescribing medicinal products. However, it is not the source most often mentioned by doctors for obtaining knowledge about medicinal products. There is a need to develop strategies and tools to provide physicians with credible sources of information.

Formulary Management Activities and Practice Implications Among Public Sector Hospital Pharmaceutical and Therapeutics Committees in a South African Province

Introduction

The World Health Organization identified Pharmaceutical and Therapeutics Committees (PTCs) at district and hospital levels as one of the pivotal models to promote rational use of medicines (RUM). This is endorsed by the Government in South Africa. Formulary development and management is one of the main functions of PTCs. This study aimed to describe the formulary management activities among PTCs in public hospitals in Gauteng Province, South Africa, following initiatives to promote RUM in South Africa.

Methods

Qualitative, nonparticipatory, observational study, observing 26 PTC meetings. Data were coded and categorized using NVivo9^® qualitative data analysis software. Themes and sub-themes were developed. The themes and sub-themes on formulary management are the principal focus of this paper.

Results

More than half of the observed PTCs reviewed their formulary lists. There was variation in the review process among institutions providing different levels of care. Various aspects were considered for formulary management especially requests for medicines to be added. These included cost considerations (mainly focusing on acquisition costs), evidence-based evaluation of clinical trials, patient safety, clinical experience and changes in the National Essential Medicines List (NEML). The tertiary PTCs mostly dealt with applications for new non-EML medicines, while PTCs in the other hospitals mainly requested removal or addition of EML medicines to the list.

Conclusion

This is the first study from Gauteng Province, South Africa, reporting on how decisions are actually taken to include or exclude medicines onto formularies within public sector hospitals providing different levels of care. Various approaches are adopted at different levels of care when adding to- or removing medicines from the formulary lists. Future programs should strengthen PTCs in specialized aspects of formulary management. A more structured approach to formulary review at the local PTC level should be encouraged in line with the national approach when reviewing possible additions to the NEML.

Study on essential drug use status and its influencing factors among cerebral infarction inpatients in county level hospitals of Anhui Province, China

BACKGROUND AND PURPOSE

Drug costs is one of the main components of hospitalization expenditure for cerebral infarction inpatients. In China, the National Essential Medicine System (NEMS) was created to relieve the heavy drug-cost burden for patients. The objective of this study was to investigate essential drug-use status and its influencing factors among cerebral infarction inpatients in county-level hospitals of Anhui province, China.

METHODS

Three county-level hospitals were selected through a multi-stage cluster random sampling method. The hospitalization cost data of cerebral infarction inpatients in the three hospitals were extracted from the Anhui provincial information platform of the New Rural Cooperative Insurance System (NCMS), and whether the proportion of essential drug cost in the total drug cost reached the median value of 33.05% which was set as the evaluation index for essential drug-use status. Questionnaires for hospitals and physicians were designed and given to them to assess influencing factors.

RESULTS

We retrieved the cost data of 2,189 inpatients from the NCMS platform and investigated 51 corresponding physicians in total. The drug costs accounted for 52.6% of the total hospitalization cost, and essential drug costs alone accounted for 37.0% of the total drug costs. The essential drug-cost proportion was high among physicians with a higher recognition degree on NEMS, older age, lower final academic degree, longer work experience and lower professional title. Married physicians and those with tight organizational affiliation also prescribed more essential drugs.

CONCLUSIONS

Increasing the proportion of essential drugs was an effective way to reduce the disease burden for cerebral infarction patients. Perfecting the NEMS, increasing government investment, reinforcing education and propaganda, and formulating relevant incentive and restrictive mechanisms were all effective ways to promote and increase the number of essential drug prescriptions written by physicians.

Ongoing Initiatives to Improve the Quality and Efficiency of Medicine Use within the Public Healthcare System in South Africa; A Preliminary Study

Introduction: South Africa has an appreciable burden of both communicable and non-communicable diseases as well as high maternal, neonatal, and child morbidity. In recent years there have been significant strides with improving the public health system, and addressing current inequalities, with the right to health a constitutional provision in South Africa. Initiatives include the introduction of National Health Insurance, programmes to enhance access to medicines for patients with chronic diseases, as well as activities to improve care in hospitals, including improving pharmacovigilance. Consequently, the objective of this paper is to review ongoing initiatives within the public healthcare sector in South Africa and their influence to provide future direction.

Method: Principally a structured review of current and planned activities.

Results: There have been a number of major activities and initiatives surrounding the availability and access to medicines in the public system in recent years in South Africa. This includes a National Surveillance Centre and an innovative early warning system for the supply of medicines as well as the development of a National Health Care Pricing Authority and initiatives to improve contracting. There have also been developments to improve the supply chain including instigating Medicine Procurement Units in the provinces and enhancing forecasting capabilities. Access to medicines is improving though the instigation of stable chronic disease management initiatives to increase the number of external pick-up points for medicines. There are also ongoing programmes to enhance adherence to medicines as well as enhance adherence to the Standard Treatment Guidelines and the Essential Medicines List with their increasing availability. In addition, there is a movement to enhance the role of health technology assessment in future decision making. Hospital initiatives include increased focus on reducing antimicrobial resistance through instigating stewardship programmes as well as improving adverse drug reaction reporting and associated activities.

Conclusion: Overall, there are an appreciable number of ongoing activities within the public healthcare system in South Africa attempting to ensure and sustain universal healthcare. It is too early to assess their impact, which will be the subject of future research.

Primary care physicians report high trust in and usefulness of the Stockholm drug and therapeutic committee's list of recommended essential medicines (the 'Wise List')

Purpose

Inappropriate use of medicines causes increased morbidity, mortality, adverse drug reactions, therapeutic failures and drug resistance as well as wastes valuable resources. Evidence-based cost-effective treatment recommendations of essential medicines are a way of avoiding these. We assessed primary care prescribers’ knowledge about and perceptions of an essential medicines formulary, as well as the reasons for adhering to the recommendations.

Methods

We conducted a web based questionnaire survey targeting all physicians working in the primary healthcare of the Stockholm healthcare region (2.3 million inhabitants), regarding the knowledge of, attitudes to and usefulness of the essential medicines formulary of the Stockholm Drug and Therapeutics Committee, the so-called Wise List.

Results

Of the 1862 physicians reached by our e-mail invitations, 526 (28%) participated in the survey. All but one respondent knew of the formulary, and 72% used it at least once a week when prescribing. The main reason for using the formulary was evidence-based prescribing; 97% trusted the guidelines, and almost all (98%) found the content easy to understand. At the same time, many prescribers thought that the annual changes of some recommendations were too frequent, and some felt that a national formulary would increase its trustworthiness.

Conclusions

We found that the essential medicines formulary was widely used and trusted by the prescribers. The high uptake of the treatment recommendations could be due to the Stockholm Drug and Therapeutics Committee’s transparent process for developing recommendations involving respected experts and clinicians using strict criteria for handling potential conflicts of interest, feedback to prescribers, continuous medical education and minor financial incentives.

High adherence to the 'Wise List' treatment recommendations in Stockholm: a 15-year retrospective review of a multifaceted approach promoting rational use of medicines

OBJECTIVES

To present the 'Wise List' (a formulary of essential medicines for primary and specialised care in Stockholm Healthcare Region) and assess adherence to the recommendations over a 15-year period.

DESIGN

Retrospective analysis of all prescription data in the Stockholm Healthcare Region between 2000 and 2015 in relation to the Wise List recommendations during the same time period.

SETTING

All outpatient care in the Stockholm Healthcare Region.

PARTICIPANTS

All prescribers in the Stockholm Healthcare Region.

MAIN OUTCOME MEASURES

The number of core and complementary substances included in the Wise List, the adherence to recommendations by Anatomic Therapeutic Chemical (ATC) 1st level using defined daily doses (DDDs) adjusted to the DDD for 2015, adherence to recommendations over time measured by dispensed prescriptions yearly between 2002 and 2015.

RESULTS

The number of recommended core substances was stable (175-212). Overall adherence to the recommendations for core medicines for all prescribers increased from 75% to 84% (2000 to 2015). The adherence to recommendations in primary care for core medicines increased from 80% to 90% (2005 to 2015) with decreasing range in practice variation (32% to 13%). Hospital prescriber adherence to core medicine recommendations was stable but increased for the combination core and complementary medicines from 77% to 88% (2007 to 2015). Adherence varied between the 4 therapeutic areas studied.

CONCLUSIONS

High and increasing adherence to the Wise List recommendations was seen for all prescriber categories. The transparent process for developing recommendations involving respected experts and clinicians using strict criteria for handling potential conflicts of interests, feedback to prescribers, continuous medical education and financial incentives are possible contributing factors. High-quality evidence-based recommendations to prescribers, such as the Wise List, disseminated through a multifaceted approach, will become increasingly important and should be developed further to include recommendations and introduction protocols for new expensive medicines.

The prescribing of generic medicines in Nigeria: knowledge, perceptions and attitudes of physicians

Generic medicines have the same efficacy and safety as originators at lower prices; however, there are concerns with their utilization in Nigeria. Objective was to evaluate physicians' understanding and perception of generics. A questionnaire was administered among physicians working in tertiary healthcare facilities in four geo-political regions of Nigeria. Questionnaire response was 74.3% (191/257) among mainly males (85.9%). The mean knowledge score regarding generics was 5.3 (maximum of 9) with 36.6%, 36.1% and 27.2% having poor, average and good knowledge respectively. Cross-tabulation showed statistical significance (p = 0.047) with the duration of practice but not with position, subspecialty or sex. The majority of respondents did not believe that generic medicines are of lower quality than branded medicines. Therapeutic failure was a major concern in 82.7%, potentially discouraging the prescribing of generics, and a majority (63.9%) did not support generic substitution by pharmacists. Knowledge gaps were identified especially with the perception of generics, which need to be addressed.

Are new models needed to optimize the utilization of new medicines to sustain healthcare systems?

Medicines have made an appreciable contribution to improving health. However, even high-income countries are struggling to fund new premium-priced medicines. This will grow necessitating the development of new models to optimize their use. The objective is to review case histories among health authorities to improve the utilization and expenditure on new medicines. Subsequently, use these to develop exemplar models and outline their implications. A number of issues and challenges were identified from the case histories. These included the low number of new medicines seen as innovative alongside increasing requested prices for their reimbursement, especially for oncology, orphan diseases, diabetes and HCV. Proposed models center on the three pillars of pre-, peri- and post-launch including critical drug evaluation, as well as multi-criteria models for valuing medicines for orphan diseases alongside potentially capping pharmaceutical expenditure. In conclusion, the proposed models involving all key stakeholder groups are critical for the sustainability of healthcare systems or enhancing universal access. The models should help stimulate debate as well as restore trust between key stakeholder groups.

Analysis of the influence of recent reforms in China: cardiovascular and cerebrovascular medicines as a case history to provide future direction

BACKGROUND

Pharmaceutical expenditure has grown by 16% per annum in China, enhanced by incentives for physicians and hospitals. Hospital pharmacies dispense 80% of medicines in China, accounting for 46% of total hospital expenditure. Principal measures to moderate drug expenditure growth include pricing initiatives as limited demand-side measures.

OBJECTIVE

Assess current utilization and expenditure including traditional Chinese medicines (TCMs) between 2006 and 2012.

METHODS

Uncontrolled retrospective study of medicines to treat cardiovascular and cerebrovascular diseases in one of the largest hospitals in southwest China.

RESULTS

Utilization increased 3.3-fold for cerebrovascular medicines, greatest for TCMs, with expenditure increasing 4.85-fold. Low prices for generics were seen, similar to Europe. However, there was variable utilization of generics at 29-31% of total product volumes in recent years. There continued to be irrationality in prescribing with high use of TCMs, and the utilization of different medicines dropping significantly once they achieved low prices.

CONCLUSION

Prices still have an appreciable impact on utilization in China. Potential measures similar to those implemented among western European countries could improve prescribing rationality and conserve resources.

Key Components of Increased Drug Expenditure in South Korea: Implications for the Future

BACKGROUND

The cost of pharmaceuticals has increased rapidly in Korea in recent years. Expenditure is likely to grow further with the policy of expanding National Health Insurance coverage for the following four disease areas: cerebrovascular and cardiovascular disease, rare diseases, and cancer. Consequently, there is a need to analyze the different components leading to this increased expenditure as a basis for suggesting future reforms in Korea.

OBJECTIVE

To quantify the impact of new and established drugs on the growth of total drug spending in South Korea in recent years, specially focusing on the differentiated components of drug spending. These include treatment expansion and drug-mix effects (switching from cheaper drugs to expensive ones and vice versa).

METHODS

A model was proposed and used to assess the impact of both new and existing drugs on changes in price, quantity, and drug mix over the 5-year period in Korea from 2006 to 2010. The database used was the National Health Insurance claims data, which covers about 97% of the total population of Korea.

RESULTS

Overall drug spending increased 1.43-fold from 2006 to 2010. Drug-mix effect (ε_t = 1.32) was the main factor contributing to increased drug spending, followed by increased drug utilization (Q_t = 1.26). For existing drugs, treatment expansion (Q_I) and drug-mix effect (ε_I) were measured at 1.28 and 1.24, respectively, while those of new drugs were 1.02 (Q_N) and 1.03 (ε_N). Therefore, existing drugs have a much greater effect on drug spending than do new drugs. According to the Anatomical Therapeutic Classification, drug spending rose most significantly for the "sensory organs" class of drugs (E_t = 1.78) followed by the "various" class (E_t = 1.68). For existing drugs in the sensory organs class (S), drug-mix effect (ε_I) was measured at 0.96. This implies that expensive drugs among existing drugs were replaced by cheaper ones. However, the quantity prescribed (Q_I) substantially increased by 1.88-fold. New drugs within this class that were more expensive than existing ones were also prescribed (ε_N = 1.09), further increasing drug expenditure in Korea.

CONCLUSIONS

We found contrasting results from previous studies. The drug-mix effect and existing drugs made the largest contribution to drug spending growth rather than new drugs. Policies targeting drug mix, such as promoting cost-effective prescription and rational use of drugs, including the use of cheaper cost generics without compromising care, should be primarily considered to help contain future drug expenditure.

Initiatives in South Africa to enhance the prescribing of generic proton pump inhibitors: findings and implications

Background: There have been multiple reforms in South Africa to conserve resources including policies to enhance generic use, such as compulsory generic substitution and copayments. However, there are concerns with the limited knowledge of their impact. Objective: The objective was to determine utilization and expenditure of different proton pump inhibitors (PPIs). Methodology: A retrospective drug utilization study was conducted on a prescription database of a medical aid administrator in 2010. Results: The limited prescribing of single-sourced PPIs accounted for 21.5% of total prescriptions. The limited use of originators omeprazole and lansoprazole accounted for 1.8 and 1.4% of total prescriptions for the molecule, respectively. Generic prices accounted for 36–68% of the originator in 2010. Patients received on average 2.91 PPI prescriptions during the year. Conclusion: Policies to enhance prescribing of generics appear working. Opportunities exist to further lower generic prices given low prices in some European countries.

Review of ongoing initiatives to improve prescribing efficiency in China; angiotensin receptor blockers as a case history

INTRODUCTION

Pharmaceutical expenditure is rising by 16% per annum in China and is now 46% of total expenditure. Initiatives to moderate growth include drug pricing regulations and encouraging international non-proprietary name prescribing. However, there is no monitoring of physician prescribing quality and perverse incentives.

OBJECTIVES

Assess changes in angiotensin receptor blocker (ARB) utilization and expenditure as more generics become available; compare findings to Europe.

METHODOLOGY

Observational retrospective study of ARB utilization and expenditure between 2006 and 2012 in the largest hospital in Chongqing district.

RESULTS

Variable and low use of generics versus originators with a maximum of 31% among single ARBs. Similar for fixed dose combinations. Prices typically reduced over time, greatest for generic telmisartan (-54%), mirroring price reductions in some European countries. However, no preferential increase in prescribing of lower cost generics. Accumulated savings of 33 million CNY for this large provider if they adopted European practices.

CONCLUSION

Considerable opportunities to improve prescribing efficiency in China.

Ongoing measures to enhance the efficiency of prescribing of proton pump inhibitors and statins in The Netherlands: influence and future implications

BACKGROUND

Multiple reforms have recently been introduced in The Netherlands to improve prescribing efficiency. These include preference pricing policies for multiple sourced products, guidelines, and quality and efficiency targets, as well as regular pharmacotherapy meetings.

OBJECTIVES

Assess the influence of these multiple measures on prescribing efficiency.

METHODS

Retrospective observational study of all reimbursed prescriptions for proton pump inhibitors and statins between 2000 and 2010 using the Genees-en hulpmiddelen Informatie Project (Health Insurance) database. Utilization measured in defined daily doses. Narrative review of reforms.

RESULTS

Reimbursed expenditure for the proton pump inhibitors fell by 58% in 2010 versus 2000 despite a threefold increase in utilization, helped by increasing utilization of generic omeprazole at only 2% of the prepatent loss price in 2010. Similarly, reimbursed expenditure for the statins fell by 14% in 2010 versus 2000 despite a 3.8-fold increase in utilization. Again, this was helped by increasing utilization of generic simvastatin at only 2% of the prepatent loss originator price.

CONCLUSION

Multiple supply and demand measures, including the preference pricing policy, appear to have appreciably enhanced proton pump inhibitor and statin prescribing efficiency, providing examples to other countries.

Possible ways to enhance renin-angiotensin prescribing efficiency: Republic of Serbia as a case history?

BACKGROUND

Multiple reforms have been instigated across Europe to enhance prescribing efficiency. Supply-side reforms in the Republic of Serbia include measures to lower the price of generics and originators, with demand-side measures including patient copayments and prescribing restrictions. Specific measures for renin-angiotensin inhibitor drugs include a 50% copayment for angiotensin receptor blockers (ARBs) versus approximately 50 cents per prescription for established angiotensin-converting enzyme inhibitors (ACEIs), as there is no perceived difference in effectiveness between the two classes.

OBJECTIVES

To assess the influence of these measures on ARB utilization, as well as reimbursed prices of ACEIs and ARBs over time.

METHOD

Observational retrospective case study of all ambulatory care patients in the Republic of Serbia's Health Insurance Fund database who were dispensed at least one ACEI or ARB alone or in combination (fixed dose combination [FDC]) between 2005 and 2011. Utilization measured in defined daily doses (DDDs) and only reimbursed expenditure (overall and expenditure/DDD) as Health Insurance perspective.

RESULTS

There was a 1.8-fold increase in renin-angiotensin inhibitor drug utilization, rising to 207.4 DDDs/1000 inhabitants per day in 2011. This is driven principally by a 19.6-fold increase in ACEI FDCs. There was only limited utilization of ARBs at just 2% of total renin-angiotensin inhibitor drugs in 2011. Reimbursed expenditure increased 2.54-fold due to an appreciable increase in ACEI FDC utilization at approximately twice the cost of ACEIs in recent years. Alongside this, we noted considerable differences in expenditure/DDD for different ACEIs. CONCLUSION & FUTURE PERSPECTIVE: High patient copayments for ARBs appreciably limited their utilization in Serbia, which mirrors the findings from other studies. Potential future measures to enhance prescribing efficiency include reference pricing for ACEIs based on the lowest price of an established ACEI. In addition, reference pricing for FDCs should be based on the reference price of the individual components combined. This builds on recent reforms restricting the reimbursement of FDCs until 3 months after individual components have been prescribed separately.

Multiple policies to enhance prescribing efficiency for established medicines in Europe with a particular focus on demand-side measures: findings and future implications

INTRODUCTION

The appreciable growth in pharmaceutical expenditure has resulted in multiple initiatives across Europe to lower generic prices and enhance their utilization. However, considerable variation in their use and prices.

OBJECTIVE

Assess the influence of multiple supply and demand-side initiatives across Europe for established medicines to enhance prescribing efficiency before a decision to prescribe a particular medicine. Subsequently utilize the findings to suggest potential future initiatives that countries could consider.

METHOD

An analysis of different methodologies involving cross national and single country retrospective observational studies on reimbursed use and expenditure of PPIs, statins, and renin-angiotensin inhibitor drugs among European countries.

RESULTS

Nature and intensity of the various initiatives appreciably influenced prescribing behavior and expenditure, e.g., multiple measures resulted in reimbursed expenditure for PPIs in Scotland in 2010 56% below 2001 levels despite a 3-fold increase in utilization and in the Netherlands, PPI expenditure fell by 58% in 2010 vs. 2000 despite a 3-fold increase in utilization. A similar picture was seen with prescribing restrictions, i.e., (i) more aggressive follow-up of prescribing restrictions for patented statins and ARBs resulted in a greater reduction in the utilization of patented statins in Austria vs. Norway and lower utilization of patented ARBs vs. generic ACEIs in Croatia than Austria. However, limited impact of restrictions on esomeprazole in Norway with the first prescription or recommendation in hospital where restrictions do not apply. Similar findings when generic losartan became available in Western Europe.

CONCLUSIONS

Multiple demand-side measures are needed to influence prescribing patterns. When combined with supply-side measures, activities can realize appreciable savings. Health authorities cannot rely on a "spill over" effect between classes to affect changes in prescribing.

Impact of delisting ARBs, apart from losartan, on ARB utilisation patterns in Denmark: implications for other countries

INTRODUCTION

Renin-angiotensin inhibitor drugs have been a target for health authority initiatives across Europe with the potential for substantial savings once generic angiotensin-converting enzyme inhibitors (ACEIs) became available without compromising care. Recently, losartan was the first angiotensin receptor blocker (ARB) to lose its patent. In Denmark, the authorities removed all other ARBs from the reimbursement list, apart from losartan, as they were all seen as essentially similar for the management of hypertension or congestive heart failure at appropriate doses, but more expensive. Similarly, all other ARB fixed-dose combinations (FDCs), apart from losartan, were removed from the reimbursement list.

OBJECTIVE

The aims of the study were to (i) assess the impact of these reimbursement changes on the subsequent utilisation of losartan and other ARBs alone or as FDCs; (ii) assess changes in the prices of losartan and other ARBs post-generic losartan to calculate potential savings; and (iii) compare the impact of the policies in Denmark with other European countries to provide guidance.

METHODOLOGY

This was a retrospective segmented regression analysis of an interrupted time-series design comparing utilisation patterns before and after the changes in ARB reimbursement status. Utilisation was measured in defined daily doses (DDDs). Changes in total expenditure and expenditure/DDD were also assessed over time.

RESULTS

Losartan utilisation grew from 31 to 33 % of total single ARB utilisation before generic losartan, to 93 % by October 2011. There was a corresponding decrease in the utilisation of all other ARBs. Both changes were significant (p < 0.001). Total expenditure on single ARBs in 2011 was 77 % below 2009 levels despite a 16 % increase in utilisation. Estimated savings were 290.5 million Danish Kroner (DKK). A similar trend was seen for losartan FDCs, which was also significant (p < 0.001).

DISCUSSION

Losartan utilisation grew appreciable following the changes. The change was much greater than seen in countries that had eased prescribing restrictions for losartan but not the other ARBs. Active therapeutic switching programmes plus education and financial incentives also significantly enhanced losartan utilisation following generics in two countries and regions; however, the increase in losartan utilisation was less than that seen in Denmark.

Influence of multiple initiatives in Sweden to enhance ARB prescribing efficiency following generic losartan; findings and implications for other countries

BACKGROUND

Encouraging the prescribing of ACEIs first line vs. angiotensin receptor blockers (ARBs) has been a health authority focus with generic ACEIs as ACEIs and ARBs have similar effectiveness and there is limited coughing with ACEIs. This includes Sweden with its multiple initiatives keeping expenditure on renin-angiotensin inhibitor drugs similar between 2001 and 2007 despite appreciably increased volumes. Generic losartan became available and was reimbursed in March 2010 providing further opportunities for the authorities in Sweden to save costs with all ARBs seen as similar in managing hypertension and CHF at appropriate doses.

AIMS

The main aim of this study was to assess changes in the utilisation of losartan vs. other single ARBs after generic losartan alongside accompanying demand-side measures. Additional aims were to (i) assess changes in the price of generic losartan and single ARB expenditure over time; (ii) suggest additional programmes, if needed; and (iii) analyse utilisation of ARB FDCs and compare with ACEI FDCs.

METHODS

Retrospective observational study using an interrupted time series design.

RESULTS

Multiple demand-side measures introduced among the 21 Counties in Sweden significantly enhanced the utilisation of generic losartan, growing from 26% to 27% of total ARBs (DDD basis) before generic losartan to 40% by August 2011. Losartan was principally generics (97% by August 2011). Expenditure/DDD for generic losartan was 10% of the pre-patent loss price in August 2011. This reduced total single ARB expenditure by 26% by the study end despite a 16% increase in utilisation. Greater utilisation of ARB FDCs than seen with ACEI FDCs. This may be due to similarities in prices between single and FDC ARBs.

DISCUSSION

Multiple demand-side measures appreciably enhanced ARB prescribing efficiency, mirroring other studies. No significant increase in losartan utilisation following generics was seen in European countries where no specific measures were instigated. Losartan price reduction was in line with expectations.

CONCLUSION

Multiple and intensive demand-side measures are needed to change physician prescribing habits. Authorities cannot rely on physicians transferring their activities from one class to another without interventions.

Changes in the utilization of venlafaxine after the introduction of generics in Sweden

BACKGROUND

There has been an appreciable increase in the prescribing efficiency of proton pump inhibitors, statins, and renin-angiotensin inhibitor drugs in Sweden in recent years. This has been achieved through multiple reforms encouraging the prescription of generics at low prices versus patented drugs in the same class. Generic venlafaxine also presents an opportunity to save costs given the prevalence of depression. However, depression is more complex to treat, with physicians reluctant to change prescriptions if patients are responding to a particular antidepressant.

OBJECTIVES

We assessed (a) changes in the utilization pattern of venlafaxine versus other newer antidepressants before and after the availability of generic venlafaxine and before and after the initiation of prescription restrictions for duloxetine limiting its prescription to refractory patients, (b) utilization of generic versus original venlafaxine after its availability, and (c) price reductions for generic venlafaxine and the subsequent influence on total expenditure on newer antidepressants over time.

METHODOLOGY

We performed interrupted time series analysis of changes in monthly reimbursed prescriptions using defined daily doses (DDDs) of patients dispensed at least one newer antidepressant from January 2007 to August 2011. DDDs was defined as the average maintenance dose of a drug when used in its major indication in adults. This included 19 months after the availability of generic venlafaxine and before initiation of prescription restrictions for duloxetine to 13 months after prescription restrictions. Total expenditure and expenditure/DDD for venlafaxine were measured over time.

RESULTS

No appreciable change in the utilization pattern for venlafaxine was observed after generic availability when no appreciable demand-side activities by the regions (counties) were implemented to encourage its use. The utilization of venlafaxine significantly increased after prescription restrictions for duloxetine. Generic venlafaxine was dispensed once available, reaching 99.6 % of total venlafaxine (DDD basis) by August 2011. There was an appreciable fall in expenditure for newer antidepressants in Sweden after generic venlafaxine despite increased utilization, helped by a 90 % reduction in expenditure/DDD for venlafaxine by the end of the study versus prepatent loss prices.

CONCLUSION

Multiple demand-side measures are needed to change physician prescribing habits. Authorities should not rely on a spillover effect between drug classes to effect change. Limited influence of prescription restrictions on the subsequent utilization of duloxetine reflects the complexity of this disease area. This is exacerbated by heterogeneous indications for duloxetine.

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

BACKGROUND

The French National Health Insurance and the Ministry of Health have introduced multiple reforms in recent years to increase prescribing efficiency. These include guidelines, academic detailing, financial incentives for the prescribing and dispensing of generics drugs as well as a voluntary pay-for-performance programme. However, the quality and efficiency of prescribing could be enhanced potentially if there was better understanding of the dynamics of prescribing behaviour in France.

OBJECTIVE

To analyse the patient and general practitioner characteristics that influence patented versus multiple-sourced statin prescribing in France.

METHODOLOGY

Statistical analysis was performed on the statin prescribing habits from 341 general practitioners (GPs) that were included in the IMS-Health Permanent Survey on Medical Prescription in France, which was conducted between 2009 and 2010 and involved 14,360 patients. Patient characteristics included their age and gender as well as five medical profiles that were constructed from the diagnoses obtained during consultations. These were (1) disorders of lipoprotein metabolism, (2) heart disease, (3) diabetes, (4) complex profiles and (5) profiles based on other diagnoses. Physician characteristics included their age, gender, solo or group practice, weekly workload and payment scheme.

RESULTS

Patient age had a statistically significant impact on statin prescribing for patients in profile 1 (disorders of lipoprotein metabolism) and profile 3 (complex profiles) with a greater number of patented statins being prescribed for the youngest patients. For instance, patients older than 76 years with a complex profile were prescribed fewer patented statins than patients aged 68-76 years old with the same medical profile (coefficient: -0.225; p = 0.0008). By contrast, regardless of the patient's age, the medical profile did not affect the probability of prescribing a patented statin except in young patients with heart diseases who were prescribed a greater number of patented statins (coefficient: 0.3992; p = 0.0007). Prescribing was also statistically influenced by physician features, e.g., older male physicians were more likely to prescribe patented statins (coefficient: 0.245; p = 0.0417) and GPs practicing in groups were more likely to prescribe multiple sourced statins (coefficient: -0.178; p = 0.0338), which is an important finding of the study. GPs with a lower workload prescribed a greater number of patented statins.

CONCLUSION

There is significant variability in the prescribing of different statins among patient and physician profiles as well as between solo and group practices. Consequently, there are opportunities to target demand-side measures to enhance the prescribing of multiple-sourced statins. Further studies are warranted, in particular in other therapeutic classes, to provide a counter-balance to the considerable marketing activities of pharmaceutical companies.

Are specific initiatives required to enhance prescribing of generic atypical antipsychotics in Scotland?: International implications

BACKGROUND

National and regional authorities in Scotland have introduced multiple measures to appreciably enhance prescribing efficiency for the proton pump inhibitors (PPIs), statins and renin-angiotensin inhibitor drugs. Generic oral risperidone recently became available in Scotland; however, schizophrenia is a complex disease with advice from respected authorities suggesting that treatment should be individualised.

AIMS

To assess (i) changes in atypical antipsychotic drug (AAP) utilisation and expenditure following the availability of oral generic risperidone in Scotland; (ii) to determine (a) current INN prescribing rates for risperidone following generic availability and (b) decrease in expenditure/DDD for generic risperidone; (iii) to suggest additional measures that could possibly be introduced in Scotland to further enhance prescribing of generic AAPs; and (iv) to provide guidance to NHS Scotland as well as other European authorities on the implications.

METHODS

Retrospective observational study and an interrupted time series design.

RESULTS

No appreciable change in the utilisation patterns of risperidone pre- and postgeneric availability. Appreciable INN prescribing averaged 93-98% of total oral risperidone. Generic risperidone was 84% below prepatent loss prices by study end, reducing annual expenditure for oral risperidone in 2010 by GB£3.19mn compared with prepatent loss situation. However, overall expenditure on AAPs increased by 42% from 2005 to 2010.

DISCUSSION

As expected, there was no change in utilisation patterns for risperidone, although potential to influence prescribing patterns. Continued high INN prescribing suggests no problems with generic risperidone in practice. Costs will start to decrease as more AAPs lose their patents (olanzapine and quetiapine). There is the possibility to accelerate this reduction through educational activities.

CONCLUSION

There is potential to realise some savings with generic AAPs. However, this is limited by the complexity of the disease area. Any measures introduced must aim at increasing the prescribing of generic AAPs first line in suitable patients.

Potential to enhance the prescribing of generic drugs in patients with mental health problems in austria; implications for the future

BACKGROUND

Scrutiny over pharmaceutical expenditure is increasing leading to multiple reforms. This includes Austria with measures to lower generic prices and enhance their utilization. However the situation for newer antidepressants and atypical antipsychotic medicines (AAPs) is different to PPIs, statins, and renin-angiotensin inhibitor drugs with greater tailoring of therapy and no wish to switch products in stable patients. Authorities welcome generics though given the high costs particularly of single-sourced AAPs.

OBJECTIVE

Assess (a) changes in utilization of venlafaxine versus other newer antidepressants before and after availability of generics, (b) utilization of generic versus originator venlafaxine, (c) price reductions of venlafaxine over time and their influence on total expenditure, (d) utilization of risperidone versus other AAPs, (e) suggest potential additional reforms that could be introduced if pertinent to further enhance the use of generics.

METHODOLOGY

A quasi-experimental study design with a segmented time series and an observational study. Utilization measured in defined daily doses (DDDs) and total expenditure per DDD and over time.

RESULTS

No appreciable changes in the utilization of venlafaxine and risperidone after generics. The reduction in expenditure/DDD for venlafaxine decreased overall expenditure on newer antidepressants by 5% by the end of the study versus just before generics despite a 37% increase in utilization. Expenditure will further decrease if reduced prescribing of duloxetine.

CONCLUSION

Depression, schizophrenia, and bipolar diseases are complex diseases. As a result, specific measures are needed to encourage the prescribing of generic risperidone and venlafaxine when multiple choices are appropriate. Authorities cannot rely on a "Hawthorne" effect between classes to enhance the use of generics. Measures may include prescribing restrictions for duloxetine. No specific measures planned for AAPs with more multiple-sourced AAPs becoming available.

Initiatives to improve prescribing efficiency for drugs to treat Parkinson's disease in Croatia: influence and future directions

Parkinson's disease (PD) is the second most common neurological disease affecting older adults. Consequently, this disease should be a focus among payers, with increasing utilization of newer premium-priced patent-protected add-on therapies to stabilize or even improve motor function over time. However, expenditure can be moderated by reforms. Consequently, there is a need to assess the influence of these reforms on the prescribing efficiency for drugs to treat PD in Croatia before proposing additional measures. Prescribing efficiency is defined as increasing the use of add-on therapies for similar expenditure. An observational retrospective study of the Croatian Institute for Health Insurance database of drugs to treat patients with PD in Croatia from 2000 to 2010 was carried out, with utilization measured in defined daily doses (defined as the average maintenance dose of a drug when used in its major indication in adults). The study years were chosen to reflect recent reforms. Only reimbursed expenditure is measured from a health insurance perspective. Utilization of drugs to treat PD increased by 218% between 2000 and 2010. Reimbursed expenditure increased by 360%, principally driven by increasing utilization of premium-priced patent-protected add-on therapies, including ropinirole and pramipexole. However, following recent reforms, reducing expenditure/defined daily dose for the different drugs, as well as overall expenditure, stabilized reimbursed expenditure between 2005 and 2010. Treatment of PD is complex, and add-on therapies are needed to improve care. Reimbursed expenditure should now fall following stabilization, despite increasing volumes, as successive add-on therapies lose their patents, further increasing prescribing efficiency.

Imperative to consider multiple initiatives to maximize prescribing efficiency from generic availability: case history from Abu Dhabi

INTRODUCTION

Pharmaceutical expenditure has risen rapidly in Abu Dhabi, resulting in policies surrounding generics. However, various circumstances will reduce potential savings, including pharmacists still being free to dispense either originator or branded generics and be fully reimbursed.

OBJECTIVES

To research the changes in utilization patterns of proton pump inhibitors (PPIs) and lipid-lowering drugs before and after combined reforms on generics; and subsequently, calculate potential savings based on 'best practices' among Western European countries.

METHODS

An uncontrolled before-and-after observational study of utilization and expenditure of PPIs, statins and ezetimibe between 2004 and 2010, as well as up to 12 months before the first generic policy, to 1 year after the second generic policy, was carried out. Utilization was converted to defined daily doses (DDDs; 2011 DDDs) and DDDs/1000 inhabitants per day. Expenditure/DDD was calculated for omeprazole and simvastatin.

RESULTS

PPI utilization rose by 6.5-fold from 2004 to 2010, principally driven by increased utilization of patent-protected PPIs, although more recently stabilization in esomperazole utilization has occurred. Similar changes were seen for statins. Introduction of best practices would reduce PPI expenditure in 2010 by 32.8 million United Arab Emirates dirham (AED; €6.26 million) and statins by over 27 million AED (€5.15 million).

CONCLUSION

Limited demand-side measures led to increased utilization of patent-protected products in Abu Dhabi following the generic reforms. Successful measures will release considerable resources.

Multiple initiatives continue to enhance the prescribing efficiency for the proton pump inhibitors and statins in Scotland

INTRODUCTION

Multiple and intensive demand measures in Scotland have appreciably enhanced prescribing efficiency for proton pump inhibitors (PPIs) and statins in 2007 versus 2001. Statin utilization enhanced by measures to increase doses prescribed, including the Quality and Outcome Framework (QoF).

AIMS

Ascertain whether the plethora of measures continue to enhance prescribing efficiency for PPIs and statins. Second, assess whether the combined impact of the QoF targets and guidance enhances the prescribing of higher strength statins, mirroring the situation in England.

METHOD

PPI and statin utilization measured in terms of defined daily doses (DDDs) and DDDs per 1000 inhabitants per day (2010 DDDs) between 2001 and 2010, number and strength of simvastatin and atorvastatin tablets dispensed, and reimbursed expenditure per DDD and 1000 inhabitants per year.

RESULTS

Expenditure per DDD for generic omeprazole in 2010 was 91% below the 2001 originator price, leading to expenditure per 1000 inhabitants for PPIs in 2010 to be 56% below 2001 despite a threefold increase in utilization. Expenditure per DDD for generic simvastatin in 2010 was 97% below the 2002 originator price. Expenditure per 1000 inhabitants for statins in 2010 only increased by 7% compared with 2001 despite a 6.2-fold increase in utilization. Utilization of higher strength statins has increased in recent years, with higher strength simvastatin (40 and 80 mg) accounting for 85% of total statins (DDD basis) in 2010.

CONCLUSION

Reforms appear to be working to further enhance prescribing efficiency. Utilization of higher strength statins in recent years should further improve outcomes.

Influence of demand-side measures to enhance renin-angiotensin prescribing efficiency in Europe: implications for the future

European countries strive to enhance prescribing efficiency. This includes renin-angiotensin drugs following the availability of generic angiotensin-converting enzyme inhibitors (ACEIs).

AIMS

To compare angiotensin receptor blocker utilization and expenditure patterns in Austria and Croatia following prescribing restrictions, as well as with other European countries introducing different supply- and demand-side measures. Lastly, to appraise the impact of generic losartan in Croatia on utilization of patented angiotensin receptor blockers.

METHOD

Observational retrospective study principally between 2001 and 2007, using defined daily doses and €/1000 inhabitants/year. Demand-side measures were based on the four 'E's - education, engineering, economics and enforcement.

RESULTS

Greater intensity of follow-up of prescribing restrictions in Croatia enhanced utilization of ACEIs versus Austria. There was high utilization of ACEIs in Scotland following intensive demand-side measures, similar to Austria and Croatia. Demand-side measures in Spain (Catalonia) and Sweden also appeared to moderate angiotensin receptor blockers utilization. The combination of measures helped stabilize expenditure on renin-angiotensin drugs when adjusted for population sizes despite appreciable increases in volumes. The only exception was Portugal, with less intensive measures.

CONCLUSION

Multiple and intensive demand-side measures enhanced prescribing efficiency. The more intense follow-up of ARB prescribing restrictions in Croatia had a greater influence on subsequent utilization patterns than Austria. Both findings confirm earlier studies. Reforms also favorably enhanced the prescribing of generic losartan once available.

The 'wise list'- a comprehensive concept to select, communicate and achieve adherence to recommendations of essential drugs in ambulatory care in Stockholm

The aim was to present and evaluate the impact of a comprehensive strategy over 10 years to select, communicate and achieve adherence to essential drug recommendations (EDR) in ambulatory care in a metropolitan healthcare region. EDRs were issued and launched as a 'Wise List' by the regional Drug and Therapeutics Committee in Stockholm. This study presents the concept by: (i) documenting the process for selecting, communicating and monitoring the impact of the 'Wise List'; (ii) analysing the variation in the number of drug substances recommended between 2000 and 2010; (iii) assessing the attitudes to the 'Wise List' among prescribers and the public; (iv) evaluating the adherence to recommendations between 2003 and 2009. The 'Wise List' consistently contained 200 drug substances for treating common diseases. The drugs were selected based on their efficacy, safety, suitability and cost-effectiveness. The 'Wise List' was known among one-third of a surveyed sample of the public in 2002 after initial marketing campaigns. All surveyed prescribers knew about the concept and 81% found the recommendations trustworthy in 2005. Adherence to recommendations increased from 69% in 1999 to 77% in 2009. In primary care, adherence increased from 83% to 87% from 2003 to 2009. The coefficient of variation (CV%) decreased from 6.1% to 3.8% for 156 healthcare centres between these years. The acceptance of the 'Wise List' in terms of trust among physicians and among the public and increased adherence may be explained by clear criteria for drug recommendations, a comprehensive communication strategy, electronic access to recommendations, continuous medical education and involvement of professional networks and patients.

Combination of prescribing restrictions and policies to engineer low prices to reduce reimbursement costs

OBJECTIVES

To primarily document the influence of recent changes in the pricing policies for generics and originators in Norway, coupled with prescribing restrictions for both the proton pump inhibitors (PPIs) and statins, on subsequent prescribing efficiency, to provide possible examples to other countries. Second, to review the impact of prescribing restrictions on ezetimibe utilization in Norway compared with other European countries, again to provide guidance.

METHODS

A retrospective observational study using data from the Norwegian Drug Wholesales Statistics to evaluate changes in utilization patterns for the PPIs and statins from 2001 to 2009, and the Norwegian Prescription Database for expenditure data from January 2004 to 2009. Reforms validated with key personnel at the Norwegian Medicines Agency.

RESULTS

Atorvastatin utilization as measured by defined daily doses decreased after prescribing restrictions. This, coupled with increased utilization of generic simvastatin at only 15% of prepatent loss prices in recent years, led to a 55% decrease in statin expenditure in Norway between 2004 and 2009 despite appreciably increased utilization. Utilization of esomeprazole also fell following prescribing restrictions, but to a lesser extent. This reduction, coupled with low prices for generics as a result of recent pricing policies, resulted in PPI expenditure decreasing by 27% during the same period despite again appreciably increased utilization.

CONCLUSIONS

Policies to reduce the price of generics have been successfully introduced in Norway despite its small population size versus a number of other Western European countries. Prescribing restrictions have also been successfully introduced, mirroring the influence with multifaceted reforms in other European countries. The same applies to ezetimibe with utilization at only 1.9% of total statin and ezetimibe utilization in 2009. However, the difference in subsequent utilization patterns for atorvastatin versus esomeprazole makes it a challenge for health authorities to predict the ultimate impact of such measures. This requires further research.

Policies to enhance prescribing efficiency in europe: findings and future implications

Introduction: European countries need to learn from each other to address unsustainable increases in pharmaceutical expenditures. Objective: To assess the influence of the many supply and demand-side initiatives introduced across Europe to enhance prescribing efficiency in ambulatory care. As a result provide future guidance to countries. Methods: Cross national retrospective observational study of utilization (DDDs – defined daily doses) and expenditure (Euros and local currency) of proton pump inhibitors (PPIs) and statins among 19 European countries and regions principally from 2001 to 2007. Demand-side measures categorized under the “4Es” – education engineering, economics, and enforcement. Results: Instigating supply side initiatives to lower the price of generics combined with demand-side measures to enhance their prescribing is important to maximize prescribing efficiency. Just addressing one component will limit potential efficiency gains. The influence of demand-side reforms appears additive, with multiple initiatives typically having a greater influence on increasing prescribing efficiency than single measures apart from potentially “enforcement.” There are also appreciable differences in expenditure (€/1000 inhabitants/year) between countries. Countries that have not introduced multiple demand side measures to counteract commercial pressures to enhance the prescribing of generics have seen considerably higher expenditures than those that have instigated a range of measures. Conclusions: There are considerable opportunities for European countries to enhance their prescribing efficiency, with countries already learning from each other. The 4E methodology allows European countries to concisely capture the range of current demand-side measures and plan for the future knowing that initiatives can be additive to further enhance their prescribing efficiency.

Usage, risk, and benefit of weight-loss drugs in primary care

Purpose. To investigate the use of the weight-loss drugs rimonabant, sibutramine, and orlistat in primary care and to characterize the patients receiving the drugs. Methods. In this retrospective, descriptive study, 300 randomly selected patients having started weight-loss drug treatment at 15 primary care centres were investigated using the patient's medical records and their complete drug purchase data. Results. Even though 48% of the patients specifically demanded drug treatment, 77% continued treatment less than one year. 28% of rimonabant patients and 32% of sibutramine patients had a history of depression or antidepressant treatment. 41% of sibutramine patients had a history of hypertension and/or cardiovascular disease. 36% had no documented weight after treatment initiation. Conclusions. These results suggest that weight-loss drug treatment was often initiated upon patient request but was of limited clinical benefit as it was managed in a large portion of Swedish primary carecenters.

Use of Generics-A Critical Cost Containment Measure for All Healthcare Professionals in Europe?

Pharmaceutical expenditures in ambulatory care rose rapidly in Europe in the 1990s and early 2000s. This was typically faster than other components of healthcare spending, leading to reforms to moderate future growth. A number of these centered on generic medicines with measures to lower reimbursed prices as well as enhance their prescribing and dispensing. The principal objective of this paper is to review additional measures that some European countries can adopt to further reduce reimbursed prices for generics. Secondly, potential approaches to address concerns with generics when they arise to maximize savings. Measures to enhance the prescribing of generics will also briefly be discussed. A narrative review of the extensive number of publications and associated references from the co-authors was conducted supplemented with known internal or web-based articles. In addition, health authority and health insurance databases, principally from 2001 to 2007, were analyzed to assess the impact of the various measures on price reductions for generic omeprazole and generic simvastatin vs. pre-patent loss prices, as well as overall efficiency in Proton Pump Inhibitor (PPI) and statin prescribing. The various initiatives generally resulted in considerable lowering of the prices of generics as well as specifically for generic omeprazole and generic simvastatin vs. pre-patent loss prices. At one stage in the UK, generic simvastatin was just 2% of the originator price. These measures also led to increased efficiency for PPI and statin prescribing with reimbursed expenditure for the PPIs and statins either falling or increasing at appreciably lower rates than increases in utilization. A number of strategies have also been introduced to address patient and physician concerns with generics to maximize savings. In conclusion, whilst recent reforms have been successful, European countries must continue learning from each other to fund increased volumes and new innovative drugs as resource pressures grow. Policies regarding generics and their subsequent impact on reimbursement and utilization of single sourced products will continue to play a key role to release valuable resources. However, there must continue to be strategies to address concerns with generics when they exist.

Initiatives to enhance the quality and efficiency of statin and PPI prescribing in the UK: impact and implications

AIM

To assess the impact of a range of national and regional initiatives introduced in the North Lancashire Teaching Primary Care Trust (NLTPCT) since 2004 to enhance the quality and efficiency of prescribing proton pump inhibitors (PPIs), statins and ezetimibe. In addition, to suggest additional measures that could be introduced in NLTPCT to further enhance the quality and efficiency of prescribing based on initiatives in other European countries.

METHOD

A before-and-after observational study was undertaken on the utilization and expenditure of prescriptions dispensed in ambulatory care in NLTPCT from 2004 to 2007. Utilization was assessed using 'defined daily doses' (DDDs) and 'DDDs/1000 inhabitants per day' and compared over the study period. Reimbursed expenditure was assessed in terms of overall expenditure, expenditure/DDD, as well as expenditure/1000 inhabitants per year.

RESULTS

The combination of measures and initiatives enhanced the utilization of generic PPIs. International Nonproprietary Name (INN) prescribing of omeprazole reached 98% of all omeprazole by 2007. The measures also resulted in limited utilization of esomeprazole and lowered reimbursed expenditure/DDD of generic omeprazole to GB pound0.13 by 2007. This was 87% below 2004 originator prices, leading to a 41% fall in PPI expenditure during the study period despite increased utilization. Utilization of statins grew by over 130% during the study period enhanced by increased utilization of high doses of simvastatin and atorvastatin following the introduction of the quality and outcomes framework. Simvastatin dominated statin utilization by 2007, with generic simvastatin accounting for over 99.5% of total simvastatin. Reimbursed expenditure/DDD for generic simvastatin was pound0.03 in 2007, 95% below 2004 originator prices, leading to a fall in overall expenditure on statins. It proved difficult to undertake an impact analysis as, typically, a range of measures were introduced sequentially and simultaneously during the study period.

CONCLUSION

The findings are in line with expectations and do provide examples to other European countries. This includes a high rate of INN prescribing, low reimbursed prices for generic simvastatin and omeprazole and growing utilization of higher strength statins. The high rate of INN prescribing reduces the need for additional measures that have been instigated in other European countries to further enhance the prescribing and dispensing of generics to fully realize the resource benefits. Additional demand side measures are feasible and have already been instigated to conserve resources.
