Immunisation

The immunisation programme in BridgeERP HMS runs your full expanded-programme-on-immunisation (EPI / KEPI) workflow: who is due, who was vaccinated, who defaulted, and how the cold chain held up. Public-health nurses record each dose against the national schedule, trace children who miss doses, and capture any adverse event following immunisation (AEFI) — all from one menu, ready for coverage reporting.

Where to find it

The day-to-day workbench is Public Health → Operations:

• Public Health → Operations → Children Due — children with a dose due, your call list.
• Public Health → Operations → Vaccinations Today — doses scheduled or given today.
• Public Health → Operations → All Vaccinations — the complete vaccination register.
• Public Health → Operations → Sessions — static, outreach, school, home and campaign sessions.
• Public Health → Operations → Defaulters — the defaulter-tracing worklist.
• Public Health → Operations → AEFI Reports — adverse-event reports.

Supporting menus: Public Health → Cold Chain (Refrigerators, Temperature Logs, Excursions), Public Health → Configuration (Schedules, Dose Protocols), and Public Health → Reporting → Coverage Reports.

Before you start

Configure the schedule before recording doses. Under Public Health → Configuration → Schedules define each antigen — its code and name, doses required, the age at dose 1, the interval between doses, route, site, dose volume and target age. This is what drives the Children Due and Next Dose Due calculations. Register your vaccine refrigerators under Cold Chain → Refrigerators so doses can be linked to the fridge they came from.

Record a vaccination

1. Open Public Health → Operations → All Vaccinations and create a new record (or open the child from Children Due).
2. Select the Patient, the Schedule (antigen) and the Dose Number.
3. Set the Vaccination Date, Batch Number, Vaccine Expiry and Manufacturer.
4. Check the VVM Status — values 1 and 2 are Use; 3 and 4 mean Discard.
5. Choose where it was Administered At (In Clinic, Outreach, School or Home) and the Refrigerator the vial came from.
6. Record the Vaccinator and confirm Parent / Guardian Consent.
7. Set the Status. A given dose is Administered; if the child did not receive it choose Refused, Contraindicated, Missed or Wasted.
8. If there is a reaction, set the Adverse Event field and, for a severe reaction, use the Create AEFI button to raise a formal AEFI report.

The system computes the Next Dose Due date from the schedule and can flag SMS/WhatsApp reminders.

Trace a defaulter

A child who misses a scheduled dose appears under Public Health → Operations → Defaulters, with the days overdue computed automatically.

1. Open the defaulter and press Start Trace to move it from Open to Tracing.
2. Record the Trace Method — Phone Call, SMS, Home Visit, Community Health Worker Referral or WhatsApp.
3. When the family responds, set the Trace Outcome (e.g. Returned for Dose, Refused, Moved Away, Deceased, Lost to Follow-up or Rescheduled).
4. Press Close to finish the trace.

Field reference

Sessions & cold chain

Outreach and campaign work is planned as a Session. Each session has a type (Static, Outreach, School, Home Visit or SIA Campaign), a target and reached count, refusals, wastage and a computed coverage percentage; it moves through Planned → In Progress → Completed. For the cold chain, log fridge temperatures under Cold Chain → Temperature Logs; any breach is captured as an Excursion so wasted stock is traceable.

Roles & access

The programme ships three groups: Immunisation User (read and basic entry), Immunisation Nurse (records doses, traces defaulters) and Immunisation Manager (configuration, schedules and coverage oversight).

Reporting

Public Health → Reporting → Coverage Reports aggregates the vaccination register into coverage figures that feed the statutory MOH returns.

Adverse events following immunisation (AEFI)

Vaccine safety is a programme obligation, and BridgeERP HMS treats it as a first-class workflow rather than a free-text note. When a reaction is observed, set the Adverse Event field on the vaccination, and for anything severe press Create AEFI to open a formal AEFI report. The AEFI record links back to the source vaccination and captures the reaction's severity (Mild, Moderate, Severe or Fatal) and its category (Local Reaction, Systemic Reaction, Anaphylaxis, Encephalopathy, Sepsis and so on), along with onset timing and outcome. Because the report carries the batch number and manufacturer through from the vaccination, a safety signal against a particular lot can be traced and the affected stock identified quickly.

Cold chain management

Potency depends on the cold chain, so the programme keeps the fridge as a managed asset. Register each unit under Cold Chain → Refrigerators, then log temperatures under Cold Chain → Temperature Logs on the schedule your guidelines require — typically twice daily. Any reading outside the safe range is captured as an Excursion, which records how long the breach lasted and which stock was exposed, so a manager can decide whether doses must be quarantined or discarded. Linking each administered dose to the refrigerator it came from closes the loop between cold-chain integrity and the child who received the vaccine, which is exactly the trail an EPI review or a recall investigation needs.

Tips & troubleshooting

Schedule (antigen) field reference

Each antigen on Configuration → Schedules carries the parameters that drive the due-date calculations and the administration record.

Dose status & VVM reference

Every dose record carries a status and, where checked, a vaccine-vial-monitor reading.

Defaulter tracing reference

The defaulter record moves through three states, with a trace method and an outcome captured along the way.

AEFI severity & category

A formal AEFI report classifies the event so safety signals can be aggregated.
