18.1 Health Commodity & Supply Chain Management (KEMSA)

18.1 Health Commodity & Supply Chain Management (KEMSA)

Quick Summary: A clinical officer running a dispensary is also the person who orders, receives, stores, issues, and accounts for every drug in the building. Commodity management questions are highly formulaic — learn the logistics cycle, the two quantification methods, First-Expiry-First-Out, the bin card versus stock control card distinction, and the months-of-stock-on-hand calculation, and this topic becomes free marks.

Why Commodity Management Is a Clinical Skill

A stock-out is a clinical event. A facility with no oxytocin has a postpartum haemorrhage problem; a facility with no artemether-lumefantrine has a malaria mortality problem. And the majority of facility-level stock-outs in Kenya are not caused by national shortage — they are caused by late ordering, inaccurate quantification, and poor record keeping at the facility itself. That is why the Council examines this, and it is why a question describing a stock-out will usually point to a facility-level failure rather than to KEMSA.

The Logistics Cycle

The cycle is closed: consumption data recorded today becomes the forecast for next quarter. A facility that does not record issues accurately cannot quantify accurately, and will oscillate between expiry and stock-out indefinitely.

KEMSA and the Devolved Pull Model

The Kenya Medical Supplies Authority (KEMSA) is the state agency mandated to procure, warehouse, and distribute health products and technologies to public health facilities across all 47 counties.

Since devolution it has operated on a pull model, sometimes described as a "supermarket" model:

• Counties receive their health commodity allocation and order and pay for what they need.
• Orders are placed through KEMSA's web-based Logistics Management Information System (LMIS), which gives facilities visibility of stock availability and real-time order-processing status.
• KEMSA prices commodities at acquisition cost plus a fee covering procurement, warehousing, and distribution, and replenishes its own stock from the proceeds.
• KEMSA clusters the counties into regions with sales and support officers, and signs memoranda of understanding with counties.

Two consequences to reason from:

1. Commodity availability is a county budget question, not only a KEMSA performance question. Neighbouring counties with the same KEMSA supplier can have very different stock positions.
2. Order fill rate — the proportion of ordered lines actually delivered — is the headline supply chain indicator. KEMSA's reported fill rate rose from roughly 40% in 2022 to above 90% by 2026, which shifts the locus of most remaining stock-outs back to facility-level forecasting and ordering discipline.

Quantification: Two Methods, Two Situations

The examinable trap: a facility that was stocked out of a drug for two months will show low recorded consumption for that drug. Ordering on the consumption method alone reproduces the shortage. Where stock-out days are known, adjust consumption for the stock-out period or switch to morbidity-based estimation.

Receiving, Storage, and FEFO

On receipt, before signing anything: check the delivery note against the order, confirm quantity and pack size, inspect physical condition, verify batch numbers and expiry dates, and confirm cold chain integrity for temperature-sensitive items. Discrepancies are recorded at the point of receipt — a signed delivery note is very difficult to dispute later.

Storage rules:

• First-Expiry-First-Out (FEFO), not first-in-first-out. Arrange stock so the earliest expiry is at the front and is issued first, regardless of when it was delivered. A batch delivered today may expire before one delivered last year.
• Store off the floor on pallets or shelving, away from direct sunlight and water, in a cool dry ventilated room.
• Keep narcotics and controlled substances under lock with a separate register.
• Keep temperature-sensitive items in the cold chain at +2°C to +8°C with a monitored, recorded temperature (see Chapter 16).
• Separate and clearly label a quarantine area for expired, damaged, or recalled stock so it cannot be issued in error.

Inventory Records: Bin Card Versus Stock Control Card

These two are confused constantly, and the distinction is a reliable examination item.

Alongside them sit the movement documents: the requisition and issue voucher (S11) used to requisition and issue stores, the counter requisition and issue voucher (S13) used to issue to service points within the facility, and the supplier delivery note.

The reconciliation rule: physical count = bin card balance = stock ledger balance. Any discrepancy is investigated and documented, never quietly adjusted. A physical count conducted monthly is the control that detects both pilferage and recording error.

Minimum, Maximum, and Months of Stock on Hand

$\text{Months of Stock on Hand} = \frac{\text{Usable stock on hand}}{\text{Average monthly consumption}}$

Set two thresholds per commodity:

• Minimum (reorder) level — the level at which you must order to avoid running out before the next delivery arrives. It reflects the lead time plus a safety buffer.
• Maximum level — the level above which stock is likely to expire before use.

Worked example. A dispensary holds 1,200 tablets of a drug. Issues over the last three months were 400, 500, and 300 tablets, so average monthly consumption is 400. Months of stock on hand = 1,200 ÷ 400 = 3 months. If the minimum is 2 months and the maximum is 4, the facility is adequately stocked and orders on the normal cycle.

Managing Stock-Outs and Expiries

When a stock-out occurs or is imminent:

1. Record the stock-out days — this is the data that protects the next forecast from being distorted.
2. Notify the sub-county pharmacist or health management team; ask about redistribution from an over-stocked neighbouring facility, which is faster than a fresh order.
3. Place an emergency order through the established channel.
4. Identify and document a therapeutic alternative from the Kenya Essential Medicines List so that clinicians are not improvising individually.
5. Inform clinical staff so that prescribing adapts, and counsel patients honestly.

When stock expires:

1. Remove it from the issuing shelf immediately and move it to the labelled quarantine area.
2. Record it on the bin card and stock ledger — an expiry is a loss that must appear in the records.
3. Report it to the sub-county pharmacist and dispose of it through the authorised route for pharmaceutical waste, with documentation.
4. Investigate the cause: over-ordering, FEFO failure, a prescribing change, or a service that stopped. Expiry is a management signal, not just a loss.

Never issue expired stock, and never return quarantined stock to the shelf.

Pharmacovigilance and Product Quality

The Pharmacy and Poisons Board is Kenya's medicines regulator, and two reporting duties fall on clinicians:

• Suspected adverse drug reactions are reported on the ADR reporting form. Report suspected reactions even when causality is uncertain — the system is designed to detect signals from accumulated suspicion, and waiting for proof defeats its purpose.
• Poor-quality, suspect, or falsified products — unusual appearance, wrong odour, broken seals, implausible packaging — are quarantined immediately and reported, so that the batch can be traced and recalled.

The link back to clinical work is direct: a cluster of treatment failures on a single batch is a quality signal, not a resistance signal, until the batch has been checked.
