Recommendations for collection and integration of community-based testing and linkage to care data into national surveillance, monitoring and evaluation systems for HIV, viral hepatitis and sexually transmitted infections: results from the INTEGRATE Joint Action
BMC Infectious Diseases volume 21, Article number: 794 (2021)
Abstract
Background
National testing strategy, including monitoring and evaluation, is critical in responding to HIV, sexually transmitted infections, and viral hepatitis. Community-based voluntary counselling and testing contributes to early HIV diagnoses among key populations. Countries providing community-based testing, should integrate some core data on testing and linkage to care in these services into national surveillance and monitoring and evaluation systems. This study aimed to support the integration of community-based voluntary counselling and testing data into respective national surveillance and M&E systems for those infections.
Methods
Preliminary consensus on indicators for the integration of community-based voluntary counselling and testing data into respective national surveillance and monitoring and evaluation systems was reached. Pilot studies were conducted in Estonia, Poland, Serbia, Slovakia, Slovenia and Spain. After pilot activities were implemented, the final consensus on indicators was reached. An analysis of the facilitators and barriers faced during pilot studies was conducted to inform the final recommendations for implementation.
Results
The minimum set of six indicators to be integrated into national surveillance and monitoring and evaluation systems were: number of tests, number of clients tested, reactivity rate for tests and clients, positivity (active infection) rates for tests and clients, linkage to care rates for clients with reactive and/or positive test result, proportion of all new diagnoses in a country with first reactive test result at community-based voluntary counselling and testing service. Seven additional indicators were identified. Each indicator should be disaggregated by key population, sex and age group. A list of 10 recommendations for the collection and integration of community-based voluntary counselling and testing data into national surveillance and monitoring and evaluation systems for HIV, sexually transmitted infections and viral hepatitis was identified.
Conclusions
Integration of some community-based voluntary counselling and testing monitoring and evaluation data into national surveillance and monitoring and evaluation systems in all pilot countries was achieved. The recommendations will support such integration in other European countries. European Centre for Prevention and Control of Diseases included questions from the minimum list of indicators into their Dublin Declaration questionnaire 2020 to contribute to evidence based community testing policies in European countries.
Background
Timely diagnosis of HIV infection, other sexually transmitted infections (STIs) such as syphilis, gonorrhoea and chlamydia infection, hepatitis B and hepatitis C is a precondition for referral to treatment, which is essential to decrease respective morbidity and mortality and prevent onward transmission of these infections. Evidence-based national testing policies and programmes aiming to reach and test those at risk for these infections have become a public health priority.
Initiatives to improve monitoring of testing and linkage to care have historically focussed on HIV. In October 2016, the European Centre for Disease Prevention and Control (ECDC) convened an expert consultation with representatives from national institutions, community organisations, and healthcare workers from 14 Member States and international organisations, to explore how to strengthen HIV testing and linkage to care monitoring in the European Union/European Economic Area(EU/EEA) countries [1]. The consensus was that improving testing policies, planning, resource allocation and program performance requires timely, accurate and high quality data on HIV testing and linkage to care locally, nationally and within the European region [1]. Recently, the focus has been broadened to include hepatitis B and hepatitis C testing, and ECDC has published Public health guidance on HIV, hepatitis B and C testing in the EU/EEA [2] that recommends testing to be conducted not only in health care settings but also in prisons, drug treatment services, harm reduction services, in the community, and by self-sampling and self-testing. The document also emphasized that an effective national testing strategy, which includes a monitoring and evaluation (M&E) framework, is critical in responding to HIV, hepatitis B and hepatitis C.
Community-based voluntary counselling and testing (CBVCT) has been shown to contribute to a sizeable proportion of new HIV diagnoses, especially among men who have sex with men (MSM) [3,4,5,6]. CBVCT services can reach key populations at higher risk of HIV infection and STIs such as MSM, sex workers (SW), people who inject drugs (PWID) and migrants [7]. Guidelines for the monitoring of HIV testing in CBVCT services have been developed by the HIV-COBATEST project [8] and are used throughout Europe, particularly in the COBATEST network, a European network of CBVCT services with the purpose of sharing common data collection instruments to monitor the activity of CBVCTs in Europe, generating, analysing and disseminating harmonised community based testing data and indicators to be used at local, national and regional level [7, 9, 10]. These guidelines promote quality and consistency in data collection, ensuring CBVCT data can be used for M&E within the service and at the national and European level [11, 12]. It is vital that countries collect at least some core data on CBVCT activity to be integrated into national surveillance systems.
The “Joint Action on integrating prevention, testing and linkage to care strategies across HIV, viral hepatitis, tuberculosis and STIs in Europe” (INTEGRATE) aimed to increase early diagnosis and linkage to prevention and care not only for HIV and viral hepatitis, but also for tuberculosis and STIs in EU Member States by 2020. It is a collaborative action among 29 partners from 16 countries participating in the third EU Health programme, funded by the European Union’s 3rd Health Programme for Research and Innovation (Grant Agreement No: 761319). One of the objectives was to support the integration of testing and linkage to care data from CBVCT services into national surveillance and M&E systems for HIV, STIs and viral hepatitis. The work focused on developing a document with consensus recommendations for collection and integration of CBVCT and linkage to care data into national surveillance systems for HIV, viral hepatitis and STIs, including an agreed list of core CBVCT M&E indicators.
This work is turn would support EU/EEA countries to have better informed CBVCT policies and programmes for these infections.
Methods
Two consensus meetings were held in Barcelona, one before and one after the implementation of pilot activities in six countries (Estonia, Slovakia, Serbia, Poland, Slovenia and Spain). The meetings brought together representatives of public health institutions and CBVCT services from each participating country.
The first consensus meeting was held in Barcelona in December 2018. A preliminary set of CBVCT M&E indicators for HIV, STIs and viral hepatitis was proposed to be integrated into national surveillance and M&E systems. The proposal was based on the outcomes of the Euro HIV EDAT project [8, 11, 12], the Dublin Declaration Monitoring questionnaire 2018 [13] and ECDC Public health guidance on HIV, hepatitis B and C testing in the EU/EEA [14]. The proposal was discussed during the meeting and a preliminary set of CBVCT M&E indicators was agreed upon to be piloted.
The partners (Centre of Epidemiological Studies of HIV/AIDS and STI of Catalonia (CEEISCAT); Institute of Public Health of Serbia “Dr. Milan Jovanović Batut” (IPH), National Aids Centre, Poland (NAC), National Institute of Public Health, Slovenia (NIJZ), Slovak Medical University (SMU), and National Institute for Health Development, Estonia (TAI)) coordinated the implementation of pilot activities in their respective country in the period 1st January 2019 to 31st June 2019. Some pilot activities were extended to 31st August 2019. Pilot activities in each country were planned based on a previous need assessment carried out in each country [15]. Pilot activities varied by country but had the common goal of evaluating the feasibility of implementing the proposed set of indicators.
The second consensus meeting with representatives from CBVCT services, national surveillance and M&E institutions from the six pilot countries was held in Barcelona in November 2019. Each pilot partner (mainly from national surveillance and M&E institutions) invited to the meeting other experts from their institutes or from other surveillance institutes, and a representative from CBVCT services in their countries, involved in the pilot activities. As part of the decision-making process, a proposal of indicators was presented, based on the initial list of indicators proposed to implement during the pilots. The consent decision rule was applied to reach a consensus on the final list of indicators. The proposal was discussed, sharing pilot partner experiences and opinions on the importance and/or feasibility of each indicator. Once the proposal was discussed and a shared understanding was established, the participants were asked to clearly stated if they object or consent to the proposal. In case of any objections, the causes were discussed, and the proposal was amended accordingly, iterating again the previous steps until everyone involved in the decision-making process had no longer meaningful objections.Previous to the meeting, the facilitators and barriers faced by each partner in implementing pilot activities [15] were analyzed, selecting the main ones that were presented in the meeting to open a discussion, in order to inform the recommendations. The same making-decision process and the consent decision rule used for the indicators were applied to reach a consensus on the final recommendations.
For the estimation of indicators in each pilot country de identified data was used.
Results
The pilot activities in each country were very different between them, and were planned according the needs assessment conducted prior to implementing the pilots. The needs assessment, the detailed planned activities and the results can be consulted in the pilots report document [15]. Table 1 summarize the pilot actions and the main outcomes assessed in each pilot country.
Several facilitators and barriers in the process of integrating CBVCT M&E indicators into the national surveillance and M&E systems for were identified by each pilot country. The summary of the main ones is presented in Table 2.
The 10 consensus recommendations for collection and integration of CBVCT testing and linkage to care data into national surveillance systems for HIV, viral hepatitis and STIs are presented in Table 3.
The main recommendation is to use for the integration the consensus set of indicators. The recommendations highlight the contribution of CBVCT services to early diagnoses of these infections, and ask for support CBVCT services, in order to get a good quality data. In order to recognize the contribution of CBVCT services to early diagnoses, is important to collect an indicator to know the proportion of new diagnosis with first reactive test at CBVCT service. The cooperation of all parties is essential, and is important to take advantage of the already data collected at CBVCT services, improving the systems, instead of duplicate reporting requirements. One of the problems detected for data integration is the lack of a unique client identifier that could be used through the continuum of HIV prevention and care.
A set of six minimum CBVCT M&E indicators to be integrated into national surveillance and M&E systems and an extended set of seven additional indicators were identified. Respective definitions, numerators, denominators and comments are given in Table 4. All CBVCT M&E indicators in the minimum set are relevant for HIV infection, hepatitis B, hepatitis C and all STIs tested for at CBVCT services.
An extended set of indicators recommended for HIV, STIs and viral hepatitis where this testing is offered in CBVCT services was also identified (Table 5). Those indicators in the extended set were considered important for CBVCT services, but no so relevant for the integration in the national surveillance and M&E systems. Some of the indicators in the extended set are only relevant for some of the infections.
During the review process of the “Consensus recommendations for collection and integration of CBVCT testing and linkage to care data into national surveillance systems for HIV, viral hepatitis and STIs”[16] document, the INTEGRATE Steering Committee suggested adding two indicators to measure the integration of testing of different diseases. Thus, the following two indicators were also included in the extended set: proportion of clients tested for HIV also tested for at least one more infection, either STI or hepatitis B or hepatitis C; proportion of clients with a reactive HIV test with at least one more reactive result for one more infection, either STI or hepatitis B or hepatitis C).
All indicators should be disaggregated by key population, sex and age group.
Discussion
In the framework of the INTEGRATE Joint Action, a minimum and extended set of CBVCT M&E indicators for integration into national surveillance and M&E systems for HIV, viral hepatitis and STIs was agreed by consensus. A list of recommendations for CBVCT services and national surveillance and M&E institutions to facilitate such data integration was also agreed.
M&E of CBVCT services is important to evaluate and improve the services and to show its contribution to early diagnosis. The COBATEST network ([7, 10, 17]) has shown the feasibility of collecting harmonised community based testing data and indicators that can be used at local, national and European level. It is vital to take into account the M&E data from CBVCT services and integrate at least some core data into national surveillance systems.
According to the results of the “Monitoring implementation of the Dublin Declaration on partnership to fight HIV/AIDS in Europe and Central Asia in 2018” [18], 41 countries reported community-based HIV testing delivered by medical providers, and 25 reported community-based HIV testing delivered by lay providers. In spite of this, only 23 of the 41 countries reporting community-based HIV testing delivered by medical providers were able to provide the number of tests performed in such settings and just 20 were also able to report positivity rate. None of the 25 countries reporting community-based HIV testing provided by lay-providers were able to provide such CBVCT M&E data.
Two European projects, HIV Community-Based Testing Practices in Europe (HIV-COBATEST) and the European HIV Early Diagnosis and Treatment Project (Euro HIV EDAT) previously developed and recommended a group of core indicators [8] to monitor and evaluate community testing, some of which have been incorporated into previous Dublin Declaration monitoring process rounds and have informed the consensus set of CBVCT M&E indicators presented here. The consensus set of indicators includes the four key metrics for testing monitoring and evaluation recommended by the ECDC Public health guidance on HIV, hepatitis B and C testing in the EU/EEA [14]: number of tests; basic demographic data of person tested (e.g., ages, sex and population group); location/setting of the tests; and number of reactive/positive tests.
The presented minimum and extended set of CBVCT M&E indicators should support national surveillance and M&E systems for HIV, STIs and viral hepatitis in integrating standardized information on testing and linkage to care from CBVCT services in respective countries. Collecting such standardized information will allow the comparison of testing and linkage to care data for HIV, STIs and viral hepatitis between different CBVCT services within and between countries.
This study had a close dialogue with ECDC from the outset, and representatives from the pilot countries also participated in the ECDC Dublin Declaration Advisory Group meeting held in ECDC in December 2019. The proposed set of core M&E indicators on HIV, STI and viral hepatitis testing and linkage to care from CBVCT services to be integrated into national surveillance and M&E systems was discussed along with its inclusion in the Dublin Declaration Monitoring 2020. Questions to obtain estimates for the majority of the minimum set of CBVCT M&E indicators (Number of tests; Number of clients tested; Reactivity rate of tests; Reactivity rate for clients; Linkage to care rate; Proportion of all new diagnoses with first reactive or positive test at a CBVCT service) for HIV have been included in the Dublin Declaration Questionnaire 2020. By collecting these estimates, ECDC and the participating countries will be generating comparable information about the impact of CBVCT services in EU/EEA countries on early diagnosis. This will inform regional policies on HIV testing, diagnosis and linkage to care for key populations (MSM, PWID, sex workers, and migrants) in the region.
The consensus recommendations will guide countries initiating or improving the process of integrating CBVCT testing and linkage to care data for HIV, STIs and viral hepatitis into their surveillance and M&E systems. The target audience for these recommendations is public health professionals who coordinate the development of national guidelines or programmes for HIV, STIs and viral hepatitis, public health professionals responsible for surveillance and M&E systems, CBVCT services, community activists and advocates, commissioners or funders of testing services.
The pilot activities highlighted barriers in the process of integrating CBVCT M&E indicators into the national surveillance and M&E systems. They included lack of communication between the different stakeholders; financial and technical capacity of CBVCT services; information technology (IT) deficits; issues around using a unique personal identifier while maintaining anonymity in CBVCT services and IT or legal difficulties to integrate different databases. Some facilitators which could facilitate the process were also identified: willingness on the part of CBVCT services; existence of the necessary data in some services which only requires improvement to the data transfer processes; existing good relationships between CBVCT services and public health institutions. The consensus recommendations may help to overcome difficulties faced by the countries in the process of integration of CBVCT M&E data into national surveillance and M&E systems.
The pilot activities in all six countries were, by and large, successful in collecting the estimates for CBVCT M&E indicators, particularly for HIV. The short duration of the pilot activities was a barrier in some countries which required major process adaptations. Some of the indicators proved to be difficult or even impossible to be estimated during the pilot period in some countries, due to client anonymity, structural or legal issues. The recommendations take these issues into account and should be considered by countries before starting the process of integrating CBVCT M&E indicators into respective national surveillance and M&E systems. Although the pilots took place in six countries, the heterogeneity of European countries means it is possible that other countries will face barriers for the implementation that have not been identified.
Conclusions and recommendations
Integration of some CBVCT M&E data into national surveillance and M&E systems in all pilot countries was achieved. The recommendations will support such integration in other European countries.
The authors recommend that all EU/EEA member states with CBVCT services should collect data for at least the minimum set of CBVCT M&E indicators for testing of HIV, STIs and viral hepatitis. If resources permit, and according to national priorities, we recommend that EU/EEA member states also consider collecting annual estimates for the extended set of CBVCT M&E indicators. The authors also recommend the publication of CBVCT M&E indicators in countries’ annual national surveillance and M&E reports, alongside contextual information about CBVCT services.
Integrating CBVCT into the national testing strategy, including the M&E framework, would assist the national response to HIV, STIs and viral hepatitis. Integrating the minimum and extended set of CBVCT M&E indicators into surveillance and M&E systems can help to determine the contribution of CBVCT to diagnosis of HIV, STIs and viral hepatitis in the country and allow the comparison of data between CBVCT services and between countries.
The project will aid the ECDC in improving the data collected in the Dublin Declaration monitoring process regarding CBVCT and will consequently inform evidence-based community testing policies for HIV, STIs and hepatitis B and C in EU/EEA countries.
