The World Health Organization (WHO) has issued new
recommendations on how to organise services in order to promote linkage to care
and retention in care as part of its new guidelines recommending
antiretroviral treatment for all adults and adolescents.
The recommendations on antiretroviral treatment and for
pre-exposure prophylaxis for people at substantial risk of HIV infection were
announced in September 2015. This week the World Health Organization makes
a series of new recommendations on service delivery. These are designed to
maximise linkage to care and retention in care as part of efforts to expand access to antiretroviral treatment to ensure that 90% of people diagnosed with HIV infection are on treatment by 2020.
HIV programmes should provide people-centred services that
are organised around the health needs and preferences of people living with HIV,
WHO says. In practice this means following the evidence regarding how to
optimise linkage and retention in care, through decentralisation of care,
reduction in clinic visits and clinic waiting times, and “upholding individual
dignity and respect, especially for vulnerable populations.”
The new recommendations, based on moderate quality evidence
from randomised studies and review of the scientific literature include:
- Routine viral load testing should be carried out
6 months and 12 months after starting antiretroviral treatment, and if the
patient is stable on ART, every 12 months thereafter.
- Less frequent clinic visits and medication
pick-ups are recommended for people on stable ART: every 3-6 months is
sufficient.
- ARVs can be distributed by trained and supervised
lay providers; lay people and other trained and supervised non-laboratory staff
can also undertake blood finger prick sampling for collection of blood for
treatment monitoring.
- Testing sites should have in place a package of
support interventions to ensure linkage to care, such as linkage to case
management or peer support and navigation. Data should be used to identify how
the quality of linkage can be improved.
- Programmes should provide community support
intervention such as adherence clubs to encourage retention in care, and
programmes should promote adherence through the use of interventions such as
peer counsellors, mobile phone text messages, reminder devices, medication
adherence training and the use of fixed-dose combinations and once-daily
therapy.
- Adolescent-friendly services should be
implemented within HIV services to improve engagement and outcomes.
In a response to the new guidelines the
International Treatment Preparedness Coalition called for the international
community “to ensure that adequate, community-led treatment education is an
integral part of treatment scale up.” They also urged government to ensure the
rapid adoption of the recommendation on viral load testing, and to ensure that
any charges to patients for viral load testing should not be a barrier to care.
The new guidelines also recommend the use of the integrase
inhibitor dolutegravir as an alternative first-line treatment adult option for the
first time. Dolutegravir was licensed to the Medicines Patent Pool by ViiV
Healthcare in 2014, allowing the drug to be used in fixed-dose combinations by
generic manufacturers supplying lower-income countries. The International
Treatment Preparedness Coalition has called on ViiV to extend the
eligibility criteria for its license to the Medicines Patent Pool to allow middle-income
countries to obtain the drug more cheaply.
Aurobindo, an Indian manufacturer, announced
this week that it will make its generic version of dolutegravir available at
$44 a year, matching the price of efavirenz for lower-income countries.
The guidelines also recommend the use of a 400mg efavirenz
dose as an alternative first-line option for adults and adolescents in order to
improve the tolerability of efavirenz, following
the finding that a 400mg dose was just as effective as a 600mg dose, but
with fewer side effects. The Indian
manufacturer Cipla announced this week that it is preparing to launch fixed-dose
combinations containing efavirenz 400mg. Mylan Laboratories will also launch
its own fixed-dose combinations in early 2016 at a price of $99. UNITAID says
that switching to a 400mg dose of efavirenz could result in savings of US$80 to 100
million globally by 2020.
