Monitoring and evaluation of hepatitis C initiatives

Published 14 May 2021

Monitoring and evaluation of hepatitis C initiatives

The coronavirus (COVID-19) pandemic, and associated restrictions, caused disruption to many healthcare services, including testing and treating for blood borne viruses such as hepatitis C virus (HCV). Health and social care services have been developing innovative ways to deliver HCV test and treat interventions and take advantage of opportunities that have arisen, such as provision of temporary housing for people experiencing homelessness.

To assist in understanding the impact of these new service delivery models, Public Health England (PHE) has developed this rapid evaluation resource that can be utilised to undertake quick and pragmatic evaluations.

Application of this tool will provide a structured overview of the impact on service users and health inequalities, and inform decision making on what should and can be amended to continue service delivery in an efficient and sustainable way.

What is evaluation

Evaluation is the activity that assesses the impact of an intervention or service (delivery) model. The terms of intervention and service delivery model are used interchangeably, but it refers to evaluation of any change in practice, for example outreach testing being undertaken in homeless hostels for the first time.

Evaluation does not need to be a complex academic exercise and should be done as a standard part of project management.

Benefits of evaluation

Evaluation results can be used to:

  • clarify objectives of the intervention
  • demonstrate whether the intervention has achieved what was intended
  • identify how we can further improve how an intervention is delivered
  • establish whether an intervention has improved or worsened health inequalities
  • demonstrate value to senior managers and commissioners (or explain why it didn’t work as intended)
  • share findings with others planning similar projects

Conducting rapid evaluations

The below questions set out in table 1 are a useful guide to structure rapid evaluations. The brief example questions provide an indication of the type of questions that can be raised.

Table 1. Rapid evaluation: 9 questions

Question Brief example
1 What was the problem you were trying to address? We aimed to improve HCV treatment uptake among people experiencing homelessness and rough sleeping in the city
2 What caused the problem? We noted that hospital appointment attendance to commence HCV treatment among this cohort was low
3 Describe the intervention We offered drop-in HCV clinics rather than set appointments in a city centre hospital outpatient clinic setting
4 What were the reasons for choosing this particular intervention? This intervention was quick and easy to pilot with minimal resource implications
5 What have you measured to demonstrate the initial problem has been addressed? See dataset table for examples
6 What were the outcomes? 65% of patients who were homeless or rough sleeping who had previously missed scheduled appointments attended the drop-in clinic; 100% were commenced on treatment during the appointment; 100% of patients attending the drop-in clinic reported it being much easier to attend; clinical staff had mixed views on the clinic model with two thirds seeing it as effective and one third feeling it was not a good use of time
7 Was the intervention delivered as planned? The intervention was delivered as planned for a 2-week pilot
8 What lessons have been learnt? Drop-in clinics are more accessible for some people living with HCV who are homeless or rough sleeping but needs to be part of a wider set of outreach interventions to engage this community with care. The wider impact of this model on other groups experiencing health inequalities for example, migrants also needs to be assessed
9 What next? We intend to pilot drop-in clinics in outreach settings for example, drug and alcohol services, alongside peer supporter provision, and capture data on service access by other vulnerable populations. We will also explore how this service can be sustained in the long term

In order to answer these questions, quantitative and qualitative data needs to be collected.

This should include the HCV intervention minimum dataset, see table 2. This minimum data set is based on requirements for national surveillance and progress towards elimination. Not all variables will be needed for evaluation purposes, but its use is strongly encouraged. For further details on using the minimum dataset and linking up with other nationally collated data, please contact the PHE Hepatitis Surveillance team at phe.hepcdiagnoses@nhs.net

Additional data that will explore other interventions on the HCV care pathway could also be considered; see table 4 for examples. What additional data that is useful to collect will depend on the specific intervention being piloted.

Staff and service users’ surveys to ascertain views on their experience of the service delivery model, its effectiveness and efficiency.

Collecting data on the denominator (for example, total number of people tested or eligible for treatment, total number of people housed in hostel setting) is very useful for calculating indicators such as uptake rate or proportion tested or treated and should be done where possible.

An example of an evaluation report that used a variety of data sources to evaluate test and treat interventions targeted at homeless populations that were housed into self-contained emergency accommodation in commercial hotels, bed and breakfast accommodations, and hostels during the pandemic, can be found at COVID-19: evaluation of hepatitis C homeless interventions.

Further resources

PHE can support service evaluations through facilitating virtual or face-to-face discussions with involved staff and stakeholders. This can be done at any stage in the project, but ideally before rolling out. This will help you to undertake a rapid evaluation that will be useful, inform further service planning, and support improving the quality and effectiveness of HCV services.

PHE facilitators will support teams to complete a structured list of 9 questions (table 1). It is anticipated that the session will run for about 90 minutes. This is a guide only and can be flexed according to need. The aim of the session is to provide time for the team to get together, to share expertise, inform local practice and explore the impact of the intervention collaboratively.

Following the session, PHE will provide a brief report to participants to take it forward.
