Chishlo is building Kenya's first national Early Hearing Detection and Intervention infrastructure. This is our blueprint: evidence-based, community-anchored, and designed to scale across all 47 counties.
"Every year, thousands of Kenyan children are born into silence — and most will not be identified until they enter school, five years too late."
Globally, 1 in every 500 newborns has significant permanent hearing loss — making it the most common sensory birth condition. In sub-Saharan Africa, that number is higher due to preventable causes including untreated jaundice, meningitis, and ototoxic medications administered without audiological oversight.
Kenya has no systematic newborn hearing screening program. Without one, children with hearing loss go undetected through birth, immunization clinics, and early childhood development — arriving at school unable to speak or communicate fully. The window for neuroplasticity-driven language acquisition closes by age 3.
The cost of inaction compounds across generations: children who cannot speak cannot learn at grade level, cannot enter formal employment, and remain in poverty cycles. A single child identified and supported early adds decades of economic participation to their community.
Four sequential stages — each with defined actors, timelines, and outcome metrics — built to function within Kenya's existing health infrastructure, not replace it.
Automated OAE/ABR testing at hospital delivery rooms, Level 4 facilities, and immunization clinics.
Birth – 1 monthFull audiological assessment at Chishlo-partnered diagnostic hubs to confirm type, degree, and laterality.
By 3 monthsFitting hearing aids, cochlear implant referral, and family-centered auditory-verbal therapy enrollment.
By 6 monthsLongitudinal tracking via digitized EHDI records, school liaison, device maintenance, and family support groups.
Ongoing"The 1-3-6 benchmark — screen by 1 month, diagnose by 3, intervene by 6 — is the global EHDI gold standard. Chishlo's model is designed around it."

Chishlo's operational model rests on three mutually reinforcing pillars — each critical, none sufficient alone. Together they create a flywheel.
Community-based screening is the foundation. Chishlo embeds trained hearing health workers into the points of care families already use — removing the barrier of specialized clinic access that keeps rural and low-income children undetected.
OAE machines deployed at Level 4 and Level 5 hospitals. Every newborn before discharge receives automated auditory screening, with results entered into the EHDI digital registry.
Partnering with CHVs (Community Health Volunteers) at Expanded Programme on Immunization clinics — the highest-attendance touch points for children under 1 — to screen infants missed at birth.
For older undetected children, Chishlo conducts annual mobile hearing screenings at ECD centers in partnership with county education offices.
Evidence: Programs integrating hearing screening into immunization schedules achieve 76% higher coverage rates than standalone audiological clinics in low-resource settings (Smith et al., 2021, Lancet Global Health).
Chishlo's field data from Nakuru and Kisumu pilot sites confirms 3.2x more cases detected via immunization integration vs. hospital-only approach.
Identification without intervention is incomplete. Chishlo operates a means-blind intervention guarantee: every child identified receives the appropriate audiological solution regardless of their family's ability to pay.
Subsidized behind-the-ear hearing aids fitted and calibrated by licensed audiologists. Includes 2-year follow-up maintenance, battery supply, and earmold replacement.
For children with profound bilateral hearing loss, Chishlo manages the referral pipeline to KNH and Aga Khan Hospital — coordinating pre-surgery audiological assessment, surgical scheduling, and post-activation AVT.
Auditory-Verbal Therapy sessions delivered at county-level hubs, supplemented by parent coaching kits enabling home practice. Tele-therapy available for remote families.
Chishlo outcome data (2022–2024): Of 312 children enrolled in our intervention program, 89% achieved age-appropriate speech milestones by 36 months post-intervention when enrolled before 12 months of age. Cost per child: approximately KSh 28,000 (USD 215) for full 3-year support.

Chishlo is not building a program. We are building infrastructure. The goal is to make Chishlo redundant — to have trained the workforce, embedded the policy, and digitized the records so that Kenya's public health system can sustain EHDI independently.
Accredited 40-hour OAE screening certification for nurses and CHVs. Partnered with Kenya Medical Training College (KMTC) to embed hearing screening in pre-service nursing curriculum.
Open-source child hearing health tracking system integrated with DHIS2 — Kenya's national health data platform. Records screening results, diagnoses, interventions, and outcomes by county.
Working with the Ministry of Health to include universal newborn hearing screening in the next revision of Kenya's National Reproductive, Maternal, Newborn, Child and Adolescent Health (RMNCAH) policy framework.
System-building precedent: South Africa's EHDI program, built over 10 years using a similar community-health-worker integration model, now screens 68% of all newborns at no marginal cost to the national budget. Chishlo's architecture mirrors this approach, adapted for Kenya's devolved county health system.

We began in 3 counties in 2022. Today, Chishlo's network spans 27 counties through a hub-and-spoke model: county audiological hubs supported by networks of trained CHVs at peripheral health facilities.
A clear causal chain connects our resources to generational change. This is how we think about it — and how funders can hold us accountable.
Every component of Chishlo's model is grounded in peer-reviewed evidence. We are practitioners of known science, not inventors of unproven approaches.

Full transparency. Below is what it costs to identify, intervene, and support one child from birth to school age — and where the funding comes from.
Approximately USD 215. For context: a single day in a NICU in Kenya costs KSh 45,000. A lifetime in a special education program costs 12x more.
Monthly giving from Kenyan and diaspora donors. KSh 2,800/month = one child per year.
Multi-year grants from international health foundations, WHO, and bilateral development funders.
CSR partnerships with Kenyan corporates. Employee giving schemes and matched donations.
In-kind support from MoH: facility access, CHV networks, DHIS2 integration. Growing toward budget line inclusion.
Monthly giving. Cancel anytime. Receipts provided.
