Update on PASCAR HT Roadmap & EBM review & purpose of the meeting

Anastase Dzudie Chair: PASCAR HT Task Force Hypertension in Africa

From 80 millions HT in 2000 to … 150 million in 2025 Unlesswe actact!! PASCAR recommendations of priority interventions to ministries of health for prevention of heart disease, diabetes and stroke in the African region: The 10 “Best buys”

(Bongani Mayosi, Heart, 2013) Outcome of the Nairobi meeting Outcome of the Nairobi meeting

 The burden of raised BP in Africa is huge

 Need for a clear policy program & guidelines, several limitations:

 Need for outcome data

Need to search for existing drug evidence (Clinical trials)

 Anticipated lack of evidence Outcome of the Nairobi meeting THE CREOLE TRIAL PROJECT TITLE : Compa rison of Thr ee Combination Therapies in Lowering Blood Pressure in Black Africans (The CREOLE study).

 Existing randomized control clinical trials (RCTs)

 Clinical practice guidelines Pan African Society of & Centre for the Development of Best Practices in Health – CDBPS

With the technical support of: African Community of Guidelines International Network – G-I-N Africa Existing Clinical Trials (CTs) for Hypertension in Africa

Pan-African Society of Cardiology Definition used for RCTs for Hypertension for Africa (NIH 2015)

Pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favourable and unfavourable effects’. Research questions

– What are the RCTs conducted for hypertension in Africa?

– Which countries have been actively involved?

– In which years were the RCTs conducted? Methods

• Systematic search using MeSH terms

• Database searched: PubMed, Cochrane Library, ISH, WHO ICT, PACTR

• Language: English, French, Spanish & Portuguese.

• No assessment of quality CT Progress 1971 to Present

With courtesy of CDBPS Preliminary results

• 84 studies, from 69 authors, in 18 countries

• published in 47 journals (9 African Journals).

• Studies ranged from between 1971 to 2015.

• NIH 2015: 32 CTs with only 22 drug trial and less than 10 were RCTs

• Old, small sample and single center studies except NOOAH (183 patients)

With courtesy of CDBPS Conclusions on CT search

• Very little knowledge on treatment of hypertension has been generated from Africa through randomised controlled trials.

• Except NOAAH, most are small sample size and single center study.

• Compared to what we need to develop evidence based guidelines , there is still a long way to go. Clinical Practice Guidelines (CPGs) for Hypertension in Africa

Pan-African Society of Cardiology Step 1: PASCAR Internal Survey Is the ministry of health of your country running a hypertension focus national program to tackle hypertension?

983 emails sent via our internal system Very much 146 answers from 40 countries (27 African)

Much

3.5% 4.9% Active

30.1% Neutral 16.1%

Not so much active

11.9% 7.7% Very dormant

25.9% No, the ministry of health of my country is NOT running a hypertension focus national program to tackle hypertension. With courtesy of George Nel Step 2: Research questions with the CDBPS – Which countries have developed or adapted guidelines for hypertension within the African region?

– Which countries have made these CPGs available either on the MOH website, medical associations or as documents to clinicians and patients?

– Which countries are using adopted but not adapted guidelines?

– Which countries have their CPGs still in the works?

– Which countries do not have CPGs for hypertension? Methods Search in May and July 2015

 Web search of guidelines and related articles: Google, and PubMed.  Hand search: MOH, WHO & association websites.  Emails authors and request for CPGs

 Languages: English-French-Spanish-Portuguese.

 Only considered existence if we received a copy

 Not considered: CPGs could not be delivered to us or if delivered CPGs were for European/South American countries. Results

CPGs Percentage Countries

Existing CPGs for Burundi, Egypt, Ethiopia, Ghana, Kenya, Lesotho, 16 (24.20%) Malawi, Mauritius, Nigeria, Rwanda, South Africa, Hypertension Sudan, Uganda, United Republic of Tanzania, Zambia

Algeria, Gabon, Democratic Republic of Congo, Comoros WHO ISH 12.90% Islands, Seycheles.

Adoption without Adaptation 3.20% Angola, Equitorial Guinea, Mozambique

CPGs in the Works 4.80% Sierra Leone, Tunisia, Cameroon

Benin, Botswana, Canary Islands, Cape Verde, Central African Republic, Chad, Côte d'Ivoire, Djibouti, Eritrea, Non-Existent or Unclear (No Gambia, Guinea, Guinea-Bissau, Liberia, Libya, Mali, evidence for existence or 56.50% Mauritania, Morocco, Niger, Republic of the Congo, Réunion, São Tomé and Príncipe, Senegal, Somalia, non-existence) Swaziland, Togo, Western Sahara, Zimbabwe, Burkina Faso, Madagascar, South Sudan.

Limitation: No assessment of quality of CPGs Anticipated Conclusions from the Warehouse 1. Lack or dormant hypertension policy in 75% of countries in Africa

2. 22.4% of countries in Africa having clinical practice guidelines for hypertension.

Next step?

• Support African MOH, medical associations medical staff and all stakeholders with the development of high quality policy programs to tackle raised BP. Urgent need for a clear policy with an Implementation and monitoring strategy
