HIV & PrEP Continuity of Care
Continuity of care, offline-first.
LenZA is a clinical workflow app that keeps HIV and PrEP patients in care across sub-Saharan Africa. It runs on any Android device with zero internet — a nurse opens it each morning and sees exactly who needs action today.
The Problem
Patients don't leave care loudly. They just stop showing up.
Every year, millions of patients on HIV treatment or PrEP quietly disengage. Facilities running on paper registers and Excel files often don't notice until it's too late — and community health workers have no structured way to know who needs a follow-up call today. Patients become formally "lost to follow-up" when a single phone call two weeks earlier could have kept them in care.

How It Works
From facility spreadsheet to a nurse's morning list.
Import Facility Data
Existing patient data imports directly from Excel — up to 137,000+ records, 106 columns, one tap. No manual re-entry, no data clerk.
Nurse Opens LenZA
Each morning, she sees who needs action today — overdue pickups, missed viral loads, interrupted treatment. No internet required.
One Tap, Full Record
Treatment history, contacts, and clinical status, organised across 5 tabs — not dumped into one long screen.
Outreach & Reports — Automatic
Patients flagged at risk are routed to community health workers. PEPFAR MER indicators generate automatically from point-of-care data.
What LenZA Does
Built for the realities of facility-level care.
Automated Patient Intelligence
6 real-time line lists — Interrupted Treatment (IIT >28 days), Lost to Follow-Up (LTFU >90 days), Missed Drug Appointment, Missed Sample Collection, Missed Biometric, and Newly Initiated Weekly — generated automatically from clinical data, boundary-tested for precision at exact threshold days.
Offline-First Architecture
Full clinical workflow with zero internet — built for remote clinics where power and connectivity are unreliable. SQLCipher-encrypted, so patient data stays protected even if a device is lost or stolen.
Smart Patient Identification
Identify returning patients using biometric face scan, plus national ID OCR — South African Smart ID, Nigerian NIN, Ugandan NIRA. Registration auto-populates from the ID card, and duplicate detection prevents ghost records.
Facility Data Import — Production Scale
Imports real 106-column facility Excel files, designed for 137,000+ records on real Android devices with batched transaction processing. Intelligent merge logic protects locked clinical baselines, and unrecognised columns are preserved rather than dropped.
Clinical Depth
131 fields. 5 tabs. Every pathway in one app.
ART (HIV+) and PrEP (HIV−) workflows organised across Summary, Clinical & Lab, Pharmacy, TB-PMTCT, and Info. LenZA supports both daily oral PrEP and long-acting injectable PrEP, including cabotegravir and lenacapavir, with automated dosing schedules and due-date tracking. Enhanced Adherence Counselling (EAC) workflow gating ensures all three counselling sessions are completed before a repeat viral load is recorded, in line with national HIV treatment guidelines.
PrEP Clinical Pathway
Built for the way PrEP is actually delivered.
PrEP at a Glance
Enrollment status, injection due dates, and pending actions in one view — built for the same at-a-glance triage nurses already use for ART, so switching between caseloads never means switching mental models.
Nothing Slips Through
Seroconversion is detected automatically from medical evidence and surfaced on the dashboard the moment a PrEP patient tests HIV-positive — no separate report to run, no delay before action can be taken.
Protocol, Enforced
The Lenacapavir 6-month injection cycle cannot begin until the Day 2 oral dose is confirmed — the app blocks the next step rather than relying on a nurse to remember the sequence.
From Confirmation to Conversion
One journey, fully tracked — start to escalation.
Day 2 oral dose confirmation, the mandatory pregnancy-test gate before initiation, and the guided ART setup that follows a seroconversion — three moments in the same patient pathway, each enforced by the app rather than left to memory.
PEPFAR & Reporting
CSV export with PEPFAR MER-aligned indicators, auto-generated from point-of-care data — DATIM-compatible, no separate reporting system needed.
Community Health Worker View
Privacy-controlled — CHWs see outreach-relevant info without full clinical detail. Structured tasks with outcome recording, plus WhatsApp reminder integration.
Patient Directory
Searchable, filterable directory by facility, LGA, or status, with a viral load suppression badge per patient — across both imported and app-registered patients.
Traction & Validation
“Brilliant, long overdue, better than TIER.net.”
