transcript

A pilot study implementing an mHealth triage intervention for health care workers at

primary health clinics in Blantyre, Malawi

Nicola DesmondLiverpool School of Tropical Medicine

Malawi-Liverpool-Wellcome Trust

Treatment seeking for acute bacterial meningitis

• More than 1 million cases of ABM annually in SSA

• Prompt treatment vital to effective management

• Late presentation identified as major contributor to high case fatality rates for ABM

Responses to ABM

Recognition

HCW diagnosis practices

Recognition of severity

Social validation of illness

Lay interpretation of symptoms

Misdiagnosis as malaria

Aims

Explore the feasibility of implementing a triage system within PHCs facilitated through the use of mHealth technologies

– To develop mHealth algorithm based on Emergency Triage component of ETAT (WHO)

– To implement prioritisation system using mHealth triage algorithm

– To encourage appropriate referral decisions to QECH & track referrals

– To evaluate triage system using mixed methods approaches

ETAT for resource-poor settings

• ETAT: Emergency Triage, Assessment and Treatment• Component of Integrated Management of Childhood

Illness (IMCI)• Identify children with immediately life-threatening

conditions • Reliance on few clinical signs• Assessment carried out quickly if negative• Easy to follow guidelines for all cadres with limited

clinical background• Easy to conduct when patients queuing

The Evaluation

mHealth tool

• Monitor patient pathways

• Assess if systematic and timely

Self completed questionnaires

• Explore accuracy of E,P and Q assignments pre and post intervention

Patient Journey Modelling

• Baseline and post intervention

• Document practice and patient flows

• Structured observations

Qualitative Interviews

• Capture staff feedback

• Impact on overall clinic management and practice

Clinician Assessment

Cadre specific levels of engagement

• Health Surveillance Assistants (HSAs) – Salaried community health workers– 10,507 (2009) across Malawi– Average clinical training of 8 weeks

• Triage conducted predominantly by Health Surveillance Assistants

• Nurses rarely involved in triage of patients

ReferralsOut of 41,358 children triaged 1.6% (644) were referred to QECH

15.5% (100) - Emergency 74.9% (482) - Priority 9.6% (62) - Queue

From the 644 referrals 37.3% (240) arrived at QECH

62.7% (404) of referrals from PHCS did not reach QECH

Successful referrals

Patient journey modelling: Bangwe

Improved patient flows

‘There is now improvement, those children don’t take long to be attended to.” HCW

‘In the past even if you come with a child who is very sick your fellow carers could not give you a chance to go in front of a queue for your child to be helped immediately but now things have improved because when a child is very sick s/he is put in front of a queue’ Carer

‘At Bangwe we are now working together as a team. It is helping us manage the children so much better. We are seeing them far more quickly than before’ HCW

Improved recognition of severe illness‘Triage is being done systematically and children with critical illnesses are being identified and treated on time’ HCW

‘Ever since ETAT started, I have never heard any news that a child died on the way or maybe in the doctor’s room’ HCW

‘I am so thankful because of what has happened today. My baby was identified among others that he was an emergency and he was taken in front of the queue to be seen immediately by the clinician and he is now better’ Carer

Conclusions

• Separation of sick from non-sick

• Paediatric definitions• Consistent quality of triage• High levels of ownership• High levels of acceptability
