USING TASK SHIFTING TO INTEGRATE MENTAL HEALTH SERVICES IN HIV/AIDS CARE IN ZIMBABWE

Background

In sub-Saharan Africa the result of poor adherence to HAART includes poor treatment outcomes and the emergence of virus resistant to first line treatment regimens. (Bangsberg 2008).

In sub-Saharan Africa depression is associated with poor adherence to ART . (Nakimuli-Mpungu 2011)

Page 3: Dixon Chibanda. Background  In sub-Saharan Africa the result of poor adherence to HAART includes poor treatment outcomes and the emergence of virus resistant

Background

Depression, which is part of a wider group of conditions referred to as common mental disorders(CMD) marked by symptoms of depression, anxiety, and somatization increase the risk of HIV disease progression and mortality (Antelman 2007)

Non-pharmacological interventions for depressive disorders have shown promising results in developing countries. (Bolton 2003; Araya 2003; Ali 2003; Rahman 2008;Patel 2011; Petersen 2012)

Background: The challenges

High migration rate of health professionals from poor to rich countries. (Dovlo 2005)

In Zimbabwe it is estimated that in the past 15 years over 50% of health professionals have migrated to South Africa, UK, Australia, and USA.

Rationale for task Shifting

In the absence of health professionals we have had to resort to task-shifting.

….the delegation of medical and health service responsibilities from higher to lower cadres of health staff, sometimes non-professionals. (Zachariah 2009)

Page 6: Dixon Chibanda. Background  In sub-Saharan Africa the result of poor adherence to HAART includes poor treatment outcomes and the emergence of virus resistant

Rationale for task shifting There is evidence supporting the use

and efficacy of using lay health workers in primary and community health care. (lewin 2005)

Task shifting is now widespread in HIV/AIDS care in sub-Saharan Africa. (Zachariah 2009)

……but with poorly defined mental health packages under the term psychosocial support/ counselling.

Lay health workers in Zimbabwe

There are over 5000 lay health workers involved in HIV/AIDS care in Zimbabwe. (Zimbabwe Aids Network-ZAN).

Most of them (85%) acknowledge the need to address depression (kufungisisa) among PLWH but lack the knowledge. (ZAN)

Integrating Mental health in HIV/AIDS care

Lay health workers: involved in routine HIV/AIDS care at community level

PMTCT: mothers attending 6 weeks

postnatal clinic visit

1.Validating tool (EPDS)

2. Training LHW in PST

3.Define stepped care and red flag

referral 4..Define outcome

measures

Local clinics (The Friendship Bench): patients utilizing

primary care services

1.Tools ( SSQ-14/ HAQol MSC)

2. Train LHW in PST3.Define steps /red

flags4. Define outcome

measures

Mental health in PMTCT program

Postnatal psychological morbidity is high in Zimbabwe. (Nhiwatiwa 1998; Stranix -Chibanda 2005)

In 2009 PND among women attending PMTCT was 30% (Chibanda 2009)

We validated the Edinburgh Postnatal Depression Scale (EPDS). (Chibanda 2009)

Trained HIV + peer counselors on how to administer EPDS & provide group problem solving therapy . (Chibanda 2011)

Page 10: Dixon Chibanda. Background  In sub-Saharan Africa the result of poor adherence to HAART includes poor treatment outcomes and the emergence of virus resistant

PMTCT

Group problem solving therapy was significantly better (p=0.009) than usual care (medication) after 6 weeks. ( Chibanda in press JIAPAC)

Lay health workers are able to screen treat and refer mothers with PND within the PMTCT program . (Stranix-Chibanda 2005; Shetty 2008; Chibanda 2010 )

Primary care mental health

Prevalence of CMD in PHC clinics 24%-30% (Patel 1997; Abas 2000; Chibanda 2011)

The City Health Department in Harare employs ~ 800 lay health workers who are involved in the provision of HIV/AIDS care at community level.

We have successfully trained lay health workers involved in HIV/AIDS care to screen for CMD and provide Problem Solving Therapy (Mynors-Wallis 2001) for depression in Mbare. (Chibanda 2011). Recently added Behavioral Activation – another simple evidenced based intervention for depression - to the skill base of lay workers (Abas, Chibanda, Wingrove, in progress)

The friendship bench

Page 13: Dixon Chibanda. Background  In sub-Saharan Africa the result of poor adherence to HAART includes poor treatment outcomes and the emergence of virus resistant

The Friendship bench

Over 4000 people have utilized the friendship bench since its’ inception in 2006, most of these being PLWH.

Using lay health workers who are already involved in routine HIV/AIDS care to provide mental health care appears to be less stigmatizing than seeing a psychiatrist or clinical psychologist. (Chibanda 2011)

Pyramid for mental health integration in HIV/AIDS care

1) lay health workers

Refer red flag cases to 2.

2) Senior counselor/nursing staff local clinic manage or refer

severe cases to 3.

3)Psychologist/psychiatrist refer to

tertiary facility. Provide weekly supervision to 2 and refer back stable

cases to 1.

Why it seems to be working

High literacy rate in Zimbabwe (90%) (UNDP 2010)

Existing tools; SSQ-14; SSQ-8 (Patel 1994)

Multiple symptoms card with 7-step intervention (Abas 1994) HAqoL(Taylor 2008)

EPDS(Chibanda 2009)

A referral system that is accepted by stakeholders.

By end of 2012 will begin a cluster randomized controlled trial of this brief psychological intervention delivered by LHW

Recommendations for integrating mental health in HIV/AIDS care Guidelines for recognition and care (MhGap) Development of standardized protocols, including

simplified guidelines. (Zachariah 2009; WHO 2007) Mental health interventions must be implemented

into existing programs. ( Collins 2006) Need to explore how to bring on board traditional

healers (Taylor 2008) Mental health professionals should assume the

role of public health consultants (Patel 2000)
