Development of a preliminary essential medicines list for Canada.

ABSTRACT:

Background

Some evidence supports the use of a short list of essential medicines to improve prescribing. We aimed to create a preliminary essential medicines list for use in Canada.

Methods

The 2013 World Health Organization Model List of Essential Medicines was initially adapted by the research team. Fourteen Canadian clinicians gave suggestions for changes to the list. Literature relevant to each unique suggestion was gathered and presented to 3 clinician-scientists who used a modified nominal group technique to make recommendations on the suggested changes. Audits of prescriptions of 2 Toronto-based family health teams (an inner city clinic and a suburban site) between Aug. 1, 2013, and July 30, 2014, were performed to identify common prescriptions that were not on the draft list. Literature relevant to these additional medications was gathered and shared with the clinician-scientist review panel to determine whether each should be added to the list, and a list was developed. The audits were repeated based on the final list to provide a preliminary assessment of the coverage of the list.

Results

The multistep process produced a list of 125 medications. The medications included on this list covered 90.8% and 92.6% of prescriptions at the inner city clinic and the suburban site, respectively. In total, 93% of the patients seen at the inner city clinic and 96% of the patients seen at the suburban clinic had all or all but 1 of their medications covered by the list.

Interpretation

A preliminary list of essential medicines was developed that covered most, but not all, prescriptions at 2 primary care sites. The list should be further refined based on wider input.

Project description:BackgroundWorldwide, many countries have developed a list of essential medicines for children to improve prescribing. We aimed to create an essential medicines list for children in Canada.MethodsWe adapted the previously created preliminary list of essential medicines for adults in Canada and the WHO Model List of Essential Medicines for Children to create a provisional list of essential medicines for children in Canada. Canadian clinicians made suggestions for changes. Literature relevant to each suggestion was presented to clinician-scientists, who used a modified nominal group technique to make recommendations on the suggestions. Ontario Public Drug Programs prescription data were reviewed to identify commonly prescribed medications missing from the list. Literature relevant to these medications was shared with a clinician-scientist review panel to determine which should be added, and a revised list was developed.ResultsA total of 76 items were removed from the list of essential medicines for adults in Canada because they were not indicated for use in children or were not relevant in the Canadian health care context; 7 medications were added to the child list based on Ontario Public Drugs Programs prescribing data and clinician-scientist review. Suggestions to add, remove or substitute medications were made by peer-reviewers and resulted in removal of 1 medication and replacement of 1 medication. The process produced a provisional list of 67 essential medications for children.InterpretationA provisional list of 67 essential medicines for children was created through a peer-reviewed, multistep process based on current clinical evidence, Canadian clinical practice guidelines and historical prescribing data. It is publicly posted at http://cleanmeds.ca/. The list should be further developed based on wider input and should be continuously revised based on emerging evidence of the safety and effectiveness of these medicines in all pediatric age groups.

Project description:BackgroundGlobally, cardiovascular disease (CVD) is a leading cause of death and disproportionately affects low- and middle-income countries (LMICs). The WHO Model List of Essential Medicines (WHO EML) is a tool for improving accessibility and availability of medicines. This study compared the 2021 WHO EML CVDs basket of medicines with latest available national essential medicines list (NEMLs) for South Africa and 15 Southern African Development Community (SADC) countries to assess consistency in CVDs medicine listing.MethodsThis descriptive, desktop review study compared SADC NEMLs. A comparator list was extracted by combining cardiovascular medicines listed in the 2021 WHO EML for adults and children. SADC country NEMLs were obtained from the WHO Essential Medicines and Health Products Information Portal. Consistency of NEMLs was calculated as a percentage coverage of CVD medicines listed in the 2021 WHO EML. SA hospital and primary health care (PHC) level NEMLs were included as separate formularies.ResultsThe SA hospital level NEML scored 70% consistency with the 2021 WHO EML. Tanzania (84%), Namibia (81%) and Angola (79%) scored the highest consistency. The mean consistency for SADC NEMLs was 66%. The lowest scoring country was Eswatini at 26%. The SA PHC NEML scored 35%. The least listed medicines were beta-blockers, angiotensin receptor blockers (ARBs), clopidogrel (43%) and paediatric formulations (furosemide (21%); digoxin (43%)). Individual antihypertensive medicines were most commonly listed. Botswana and Lesotho were the only countries to list a single pill combination (SPC) for the treatment of hypertension.ConclusionsThis comparison indicates that South Africa and most SADC countries are aligned with 2021 WHO EML recommendations. The inclusion of age-appropriate formulations for children as well as ARBs and SPC for the treatment of hypertension may improve patient adherence and cardiovascular outcomes in these countries. More frequent updates to NEMLs should improve consistency. NEMLs were not available for two countries, and these therefore did not form part of this study. Country health expenditure in ranking the consistency of NEMLs was not accounted for. LMICs adopting the essential medicine list strategy should consider imposing minimum consistency thresholds to the WHO EML to improve accessibility and availability of CVD medicines.Trial registrationNot applicable.

Project description:BackgroundNon-communicable diseases (NCDs) are the leading cause of death worldwide. Inadequate and inequitable access to essential NCD medicines is a major concern, particularly in low- and middle-income countries. National Essential Medicines Lists (EMLs) are important policy tools that indicate which medicines are prioritized as essential within a country's health system. This study sought to analyze a wide range of national essential medicines lists (EMLs) for their inclusion of priority non communicable disease (NCD) interventions recommended by the World Health Organization (WHO).MethodsThree lists of WHO endorsed priority NCD interventions were included. A database with 137 national EMLs and the WHO EML was created from the WHO Repository and these EMLs were compared for listing of priority NCD interventions.ResultsAcross 137 countries with national EMLs, the median percentage of 20 Best Buys interventions listed was 90% (IQR 80-95) and 31 Package of essential noncommunicable disease interventions (PEN) interventions listed was 94% (IQR 90-97), of 9 HEARTS interventions was 100% (IQR 89-100), and of the 43 unique interventions across the three priority lists was 88% (IQR 84-93). Less than 80% of the 43 interventions were listed by 22 (16%) countries and less than half of the interventions were listed by 2 countries: Angola (35%) and Cambodia (23%). Interventions listed on the fewest number of national EMLs were: influenza vaccine, HPV vaccine, hepatitis B vaccine, cervical cancer chemotherapy, codeine, promethazine, senna, and oxygen.ConclusionMost NCD interventions have been prioritized in national policy in most cases. The majority of priority medicines for NCDs described within key WHO NCD technical packages are listed on nearly all national EMLs across 137 countries of all income levels. Most NCD interventions have been prioritized in national policy in most cases, but in some countries and for select interventions such as the HPV vaccine, prioritization may be reviewed.
