Neonatal Drug Formularies-A Global Scope

Neonatal drug information (DI) is essential for safe and effective pharmacotherapy in (pre)term neonates. Such information is usually absent from drug labels, making formularies a crucial part of the neonatal clinician's toolbox. Several formularies exist worldwide, but they have never been fully mapped or compared for content, structure and workflow. The objective of this review was to identify neonatal formularies, explore (dis)similarities, and raise awareness of their existence. Neonatal formularies were identified through self-acquaintance, experts and structured search. A questionnaire was sent to all identified formularies to provide details on formulary function. An original extraction tool was employed to collect DI from the formularies on the 10 most commonly used drugs in pre(term) neonates. Eight different neonatal formularies were identified worldwide (Europe, USA, Australia-New Zealand, Middle East). Six responded to the questionnaire and were compared for structure and content. Each formulary has its own workflow, monograph template and style, and update routine. Focus on certain aspects of DI also varies, as well as the type of initiative and funding. Clinicians should be aware of the various formularies available and their differences in characteristics and content to use them properly for the benefit of their patients.

Pharmacology for physician associate programmes: a collaborative, flexible and responsive approach to curriculum design

There are more than 2,000 physician associates (PAs) in the UK working in general practice and secondary care, and that number is growing. The NHS estimates that there will be over 5,900 PAs in the UK by the end of 2023. Currently, PAs in the UK are unable to prescribe medication due to the absence of statutory regulation and the necessary prescribing legislation. The Department of Health and Social Care, with the support of the four UK governments, recently announced the introduction of statutory regulation of medical associate professionals, which includes PAs. The General Medical Council will be the statutory regulator. A working group is now considering prescribing authority, scope of practice, education training and delivery, and how this will be achieved. At St George's, University of London, we teach applied pharmacology as part of the core curriculum for PAs.

Development and Evaluation of a Web-Based Paediatric Drug Information System for Germany

Background: Off-label use is frequent in paediatrics but that does not necessarily mean that the risk-benefit ratio is negative. Nevertheless, evidence-based data is essential for safe drug therapy. In Germany, there is no publicly available compendium providing transparent, evidence-based information for paediatric pharmacotherapy to date. This work describes the development of a web-based paediatric drug information system (PDIS) for Germany and its evaluation by health care professionals (HCP). Methods: Since 2012, a PDIS is being developed by the authors and is supported by the Federal Ministry of Health since 2016. Dosing recommendations were established based on systematic literature reviews and subsequent evaluation by clinical experts. The prototype was evaluated by HCP. Based on the results, the further development was concluded. Results: 92% of HCP believed that the PDIS could improve the quality of prescribing, as currently available information is deficient. Besides the license and formulations, dosing recommendations were the most relevant modules. A dosage calculator was the most wanted improvement. To facilitate sustainability of future development, a collaboration with the Dutch Kinderformularium was established. As of 2021, the database will be available to German HCP. Conclusion: The fundamentals for a German PDIS were established, and vital steps were taken towards successful continuation.

Low-Income Childless Adults' Access To Antidiabetic Drugs In Wisconsin Medicaid After Coverage Expansion

Medicaid coverage was expanded for childless adults in Wisconsin through an amended Section 1115 demonstration waiver on April 1, 2014. Coverage for prescription drugs was expanded via copayment reductions and a drug formulary expansion. We analyzed administrative drug claims data to evaluate changes in the use of and out-of-pocket spending on antidiabetic drugs among childless adults who experienced the drug coverage expansion. Compared to parents or caretakers, who were not affected by the expansion, childless adults experienced a significant increase of 4 percent in the use of antidiabetic drugs-driven mainly by an increase in the population using the drugs, rather than by more intense use. The expanded drug coverage also reduced the burden of out-of-pocket spending for childless adults by 70 percent. Our findings demonstrate that expanding prescription drug benefits led to increased access to antidiabetic drugs for childless adults in Wisconsin Medicaid.

Biosimilar Uptake in Medicare Part B Varied Across Hospital Outpatient Departments and Physician Practices: The Case of Filgrastim

OBJECTIVES

To examine the uptake of filgrastim-sndz (Zarxio), the first biosimilar to launch in the United States, in the Medicare Part B fee-for-service program from its launch in September 2015 to December 2017 and compare characteristics of patients and facilities that used filgrastim-sndz or originator filgrastim (Neupogen).

METHODS

The 20% sample of Medicare Part B fee-for-service administrative claims data was used to extract information on claims for any filgrastim product between January 1, 2015 and December 31, 2017.

RESULTS

The utilization of filgrastim-sndz in Medicare Part B increased sharply between January and August 2016, surpassing filgrastim by November 2017, contributing to a 30% decrease in overall spending on this drug since 2015. Uptake was faster and larger in physician practices compared with hospital outpatient departments. About 77% of patients receiving filgrastim-sndz were new users. Utilization patterns indicated that product selection occurred at the facility level, rather than being at the discretion of the prescribing physician or driven by patient characteristics.

CONCLUSION

Uptake of biosimilar filgrastim in the Medicare Part B program occurred despite multiple challenges to the adoption of biosimilars in the US market, suggesting that substantial potential savings could be generated by improving biosimilar uptake. Our findings indicated that physician practices and hospital outpatient departments have distinctive biosimilar uptake patterns. Thus policy makers aiming to contain Medicare Part B spending might consider focusing on incentivizing biosimilar uptake among hospital outpatient departments.

Drug and therapeutics committees in Nigeria: evaluation of scope and functionality

Introduction: Inappropriate use of medicines remains a problem, with consequences including increasing adverse drug reactions (ADRs) and prolonged hospitalizations. The Essential Medicines List and Drug and Therapeutics Committees (DTCs) are accepted initiatives to promote the rational use of medicines. However, little is known about DTC activities in Nigeria, the most populous African country. Areas covered: A cross-sectional questionnaire-based study was conducted among senior pharmacists, consultant physicians, and clinical pharmacologists in 12 leading tertiary health-care facilities across Nigeria. Expert commentary: Six (50%, 6/12) health-care facilities had existing DTCs with three (50%) having a subcommittee on antimicrobials. Seventy-five percent had infection control committees, with presence even in centers without DTCs. Chairpersons and secretaries of the DTCs were predominantly physicians (83.3%) and pharmacists (100%), respectively. Hospital formularies were available in five facilities with DTCs, while one facility without a DTC had an Essential Medicines Committee responsible for developing and updating the hospital formulary. The evaluation of ADRs was undertaken by pharmacovigilance units in nine facilities. Overall, DTCs were present in only half of the surveyed facilities and most were performing their statutory functions sub-optimally. The functioning of DTCs can be improved through government directives and mechanisms for continuous evaluation of activities.

Analysis of the drug formulary and the purchasing process at a Moroccan university medical center

AIM

To give an overview of the pharmaceutical policy in the largest medical center in Morocco, a developing country in socio-economic transition.

METHODS

This is an analytical descriptive study of the drug formulary and the purchasing process carried out at the Ibn Sina University Medical Center.

RESULTS

Our formulary included 830 drugs belonging to 14 classes according to the Anatomical, Therapeutic and Chemical (ATC) Classification System. There was a respective predominance of class N (21.8%), class B (13.5%), and class J (12.6%). Injectable route was dominant (46%). Drugs had a significant actual benefit in 70% (according to the French Data), reimbursable in 42.8%, essential in 29.2% according to World Health Organization (WHO) list, and in 36.9% according to the Moroccan list. The calls for tenders included 542 drugs representing 65% of the formulary, and the attribution rate was 71%. The main reason for non-attribution was the lack of offers. Generics accounted for 45% by volume and 26.5% by value.

CONCLUSION

With this first study, we were able to identify key indicators on drugs used in the largest medical center in Morocco. The current challenge is to introduce pharmacoeconomics in decision making concerning the updates of the drug formulary.

Impact of a transition to more restrictive drug formulary on therapy discontinuation and medication adherence

WHAT IS KNOWN AND OBJECTIVE

There is conclusive evidence demonstrating that formulary restrictions are associated with reduced utilization and pharmacy spending of the restricted drugs. However, prior efforts to implement restrictive formularies have been associated with inconsistent rates of therapy discontinuation and mixed impacts on adherence to therapy. Also, the impact of transferring patients from an already restrictive formulary to a more aggressive model has not been previously examined. This study evaluated the impact of implementation of a more restrictive formulary on therapy disruption, adherence rates, pharmacy costs and generic utilization among patients with common chronic conditions.

METHODS

In 2014, CVS Health implemented Value Formulary (VF), a restrictive benefit design with the aim of reducing spending while preserving access to and adherence to essential therapy, was used. A retrospective cohort study was conducted to assess changes in therapy disruption rates, pharmacy costs and generic dispensing rate (GDR) (for continuers) and medication adherence (for initiators) following the implementation of VF. The study group was selected from members of three existing employer clients transitioned from standard formulary (SF) to VF on January 2014. The control population was a matched group of six employers with the same preperiod formulary structure, business unit, adherence programmes and patient out-of-pocket cost as the study group. The control group retained SF in 2014. To assess therapy disruption after VF implementation, we categorized patients by their subsequent medication use into three groups: (i) therapy stopped, (ii) therapy continued and (iii) therapy switched. Medication adherence was measured as monthly proportion of days covered (PDC). Pharmacy cost and GDR were measured per utilizer per month (PUPM). Rates of therapy disruption in study and control groups were compared using the chi-square test. Differences in monthly PDC between matched groups were evaluated using multivariate linear regression. Impact of VF on pharmacy cost and GDR was measured through segmented regression of interrupted time series data with generalized estimating equations.

RESULTS AND DISCUSSION

A transition from SF to VF influenced drug coverage for approximately 13% of members (as their medications were either no longer covered, or covered restrictively under VF). Compared to patients whose plan sponsors retained SF, the patients that transitioned to VF had a modest (1·3%) but statistically significant increase in therapy discontinuation rates. This was offset by similarly modest improvements in adherence; patients who initiated therapy under VF demonstrated a 1·5% higher adherence to medications as compared to SF patients (P < 0·001). Medication costs in the VF group were lower by $20 PUPM (P < 0·001), and GDR was greater by 4·2% (P < 0·001).

WHAT IS NEW AND CONCLUSION

Transition of patients to a more restrictive drug formulary led to modest therapy discontinuation, similarly modest improvements in medication adherence and substantial prescription drug cost savings. As healthcare payors search for ways to control the rapid rise in spending for medications without compromising quality, the Value Formulary can serve as a useful tool.

Racial differences in the usage of information technology: evidence from a national physician survey

Information technology (IT) is a key mechanism for improving the quality of healthcare and containing costs, but racial differences in the utilization of IT among practicing physicians are unknown. The current study, using a national physician survey (n = 6,628), investigated racial differences in the utilization of IT. White physicians and minority physicians were directly compared. We first conducted both descriptive and inferential analyses to detect the difference in IT utilization by race and then performed multiple logistic regressions to test whether race remains significant in relation to IT utilization. Results reveal racial differences in the usage of IT. Compared to their minority counterparts, white physicians underutilized a preventive service reminder system. On the other hand, white physicians favored utilizing electronic communications with patients and exchanging clinical data and images with other providers.

Alternate financial incentives in multi-tiered formulary systems to improve accountability for outcomes

BACKGROUND

Drug manufacturer rebates paid to health plans and pharmacy benefit management companies have come under increased public scrutiny. Over the past several years, numerous articles have appeared in the literature encouraging a shift to a more quality-based decision-making process for health plan drug formularies.

OBJECTIVE

To propose a new basis for formulary placement decisions that would include consideration of health-plan-specific measures (clinical outcomes, total cost, adherence, and appropriateness of care) and align incentives for health plans, physicians, pharmacists, and pharmaceutical companies to promote high-quality care.

SUMMARY

The proposed approach builds on key components of the Pharmacy's Framework for Drug Therapy Management in the 21st Century and the Academy of Managed Care Pharmacy's Format for Formulary Submission, including a focus on patient outcomes and evidence-based decision making. The proposed approach would lessen the influence of drug manufacturer rebates on formulary placement by shifting the focus to appropriateness of care, clinical outcomes, patient adherence, and total cost of care. Pharmaceutical manufacturers would benefit from the focus on adherence to drug therapy and total cost of care. Health plans and pharmacy benefit management companies would gain in that they may be able to reduce efforts in drug utilization review as pharmaceutical manufacturers are given incentives to market their drugs more appropriately. Physicians and pharmacists would benefit because the rebate money would be used to provide quality-based financial incentives related to adherence and appropriate use of drugs.

CONCLUSION

The implementation of this approach would be difficult and require cooperation from employers, pharmacists, pharmaceutical manufacturers, health plans, and pharmacy benefit management companies. Aspects of this approach could be incorporated into existing pharmacy benefit management processes to encourage the delivery of high-quality health care.
