## 문제

Situation: A public health nurse at a Rural Health Unit (RHU) supervises the rural health midwives and the barangay health workers (BHWs) who serve families with young children.

The nurse is preparing for an immunization day in one barangay. Which task should she assign to a BHW?

## 보기

1. Screening each child for fever and other contraindications before vaccination
2. Plotting each child's weight and referring those below the normal line
3. Listing due children from household records and reminding families **✔ 정답**
4. Checking each vaccination card to identify which catch-up doses are due

**정답: 3**

## 해설

BHWs are volunteers accredited through the local health board who support primary health care through health education, household records, reminders, and follow-up. Screening for contraindications, giving vaccines, and deciding on referrals need licensed health personnel. The nurse remains accountable for the tasks she assigns and supervises.

Role of the Barangay Health Worker in Immunization Activities

The task that can be safely delegated to a barangay health worker (BHW) is listing due children from household records and reminding families. BHWs are trained community volunteers whose scope of practice centers on health promotion, community mobilization, and supportive follow-up rather than clinical assessment or clinical decision-making. In a rural health unit, the nurse or midwife remains responsible for any action that requires professional judgment.

Screening for fever and contraindications is a clinical assessment that must be performed by a licensed health professional. Deciding whether a child can safely receive a vaccine requires evaluating temperature, acute illness, allergy history, and prior adverse events. A BHW may observe and report, but cannot make the final determination to proceed with vaccination. Similarly, plotting weight on a growth chart and deciding that a child is “below the normal line” involves interpretation of anthropometric data and referral judgment, which falls under the nurse’s or midwife’s accountability. Checking vaccination cards to identify catch-up doses also requires understanding the national immunization schedule, contraindication intervals, and dose validity—clinical reasoning that is not within the BHW’s delegated role.

By contrast, listing due children from household records and reminding families is a task grounded in community health work. BHWs maintain updated household lists, know which children live in their catchment area, and can remind caregivers about the immunization schedule. This aligns with the evidence that community-based tracking and reminder strategies improve immunization coverage in low- and middle-income settings. A Cochrane review of interventions in low- and middle-income countries found that community health workers and lay health workers who conduct home visits, provide education, and track defaulters contribute to higher vaccination uptake [1]. A scoping review similarly identified community engagement and defaulter tracing as effective delivery-system interventions [3]. In a randomized pilot study in rural India, face-to-face communication and mobile phone reminders delivered through community-level workers strengthened vaccination demand and follow-up .

Watch out! The key distinction is not whether the task is “simple” but whether it requires clinical assessment, interpretation, or independent decision-making. Listing and reminding are administrative and supportive; screening, plotting with interpretation, and identifying due catch-up doses are clinical.

Key point! The nurse who assigns a task to a BHW remains accountable for that delegation. Assigning a clinical screening task to an unlicensed volunteer would place both the child and the BHW at risk, and would violate the principle that professional accountability cannot be delegated. The correct assignment is therefore the one that uses the BHW’s community linkage and record-keeping role without crossing into clinical territory.References (research sources)

## 임상 시나리오

BHW Immunization Task DelegationSafe assignment in a rural immunization day
Assign the BHW to list due children from household records and remind families. This is a community health support task within the BHW role.

Keep clinical screening, weight interpretation, and catch-up dose identification with the nurse or midwife. These require licensed professional judgment.

CautionThe nurse remains accountable for all assigned tasks and must provide supervision even when a BHW performs reminders and follow-up.

## 핵심 개념

- **BHW** — Barangay Health Worker; trained community volunteer supporting health education, records, reminders, and follow-up under supervision.
- **Delegation** — Assigning a task while retaining accountability; clinical judgment tasks remain with licensed personnel.
- **Contraindication screening** — Pre-vaccination assessment of fever, acute illness, allergy history, and prior adverse events by a licensed professional.
- **Catch-up dose** — A vaccine dose given to a child who missed a scheduled dose; identification requires clinical scheduling knowledge.
- **RHU** — Rural Health Unit; primary care facility where nurses supervise midwives and BHWs.
