The availability of safe, effective, and high-quality medicines in a hospital largely depends on efficient procurement and proper warehousing. Hospital pharmacy departments are responsible for ensuring that drugs and pharmaceutical supplies are purchased from reliable sources, stored under recommended conditions, and distributed without interruptions. A well-organized procurement and warehousing system reduces wastage, prevents stock-outs, ensures patient safety, and supports overall hospital functioning.
Definition of Procurement
Procurement refers to the systematic process of identifying, sourcing, purchasing, and obtaining medicines, medical supplies, and pharmaceutical products required for patient care. It involves selecting suppliers, negotiating prices, ensuring quality, and maintaining adequate stock levels.
Objectives of Drug Procurement
- Ensure continuous availability of essential medicines.
- Purchase drugs of assured quality and safety.
- Obtain medicines at the most economical cost.
- Reduce wastage due to expiry, damage, or overstocking.
- Promote rational and evidence-based drug selection.
- Strengthen supplier relationships and supply-chain efficiency.
Principles of Effective Procurement
- Right Quality: Choose drugs meeting pharmacopeial and regulatory standards.
- Right Quantity: Avoid over- or under-stocking.
- Right Time: Ensure timely procurement to prevent shortages.
- Right Source: Purchase from approved, licensed suppliers.
- Right Price: Use competitive bidding and negotiations.
Drug Procurement Process
The procurement cycle includes several coordinated steps to ensure timely and cost-effective purchases.
1. Identification of Drug Requirements
- Based on hospital formulary and essential drug list.
- Consumption trends and seasonal disease patterns.
- Feedback from clinical departments.
2. Estimation of Quantities Needed
- Average consumption method.
- Minimum–maximum stock method.
- Lead time and buffer-stock calculation.
3. Supplier Selection
Hospitals evaluate suppliers based on:
- License and regulatory compliance.
- Quality assurance systems (GMP, ISO certification).
- Financial stability and past performance.
- Pricing, delivery timelines, and reliability.
4. Ordering Procedure
- Purchase order approved by pharmacy and administration.
- Competitive bidding or rate contract methods used.
- Emergency procurement procedures for urgent needs.
5. Receipt of Materials
- Verification of quantity, batch number, and expiry date.
- Inspection for damage or contamination.
- Approval by quality control or pharmacy officer.
- Entry into stock registers and computer systems.
6. Payment and Record Maintenance
- Invoice checking and verification.
- Processing payments through hospital finance department.
- Maintaining procurement records for audit.
Warehousing of Drugs and Pharmaceuticals
Warehousing plays a crucial role in maintaining drug quality, preventing deterioration, and ensuring smooth drug distribution throughout the hospital.
Objectives of Proper Warehousing
- Maintain drug stability and safety.
- Organize stocks for quicker retrieval and distribution.
- Prevent contamination, theft, and damage.
- Ensure cold-chain maintenance for temperature-sensitive drugs.
Characteristics of an Ideal Drug Warehouse
- Clean, well-ventilated environment to maintain drug stability.
- Ample storage space with proper shelving and racks.
- Protection from heat, humidity, pests, and sunlight.
- Designated areas for narcotics, flammable products, and hazardous materials.
- Adequate security systems and controlled access.
Storage Conditions
- Ambient Storage: 15–25°C for most pharmaceuticals.
- Cold Storage: 2–8°C for vaccines, insulin, and biologics.
- Freezer Storage: –10°C or below for specific items.
- Dry Storage: Low humidity areas for hygroscopic drugs.
Warehouse Organization Systems
1. Alphabetical Arrangement
Drugs arranged from A–Z for easy retrieval.
2. Pharmacological or Therapeutic Classification
Grouping of drugs based on their therapeutic category (e.g., antibiotics, antihypertensives).
3. FEFO and FIFO Methods
- FEFO (First-Expired, First-Out): Items with earlier expiry are issued first.
- FIFO (First-In, First-Out): Older stock is used before new stock.
Cold Chain Management
Ensuring stability of temperature-sensitive medicines is essential.
- Use of refrigerators, cold rooms, and insulated carriers.
- Continuous temperature monitoring with alarms.
- Proper storage of vaccines and biologics.
Documentation in Warehousing
- Stock registers
- Bin cards and shelf cards
- Temperature logs
- Expiry and slow-moving item reports
- Goods receipt and inspection notes
Common Problems in Warehousing
- Overstocking leading to expiry and wastage.
- Inadequate temperature control.
- Poor documentation or mismatched records.
- Pest infestation and contamination.
- Delayed distribution to clinical areas.
Role of the Pharmacist in Procurement and Warehousing
- Estimate drug requirements scientifically.
- Select reliable suppliers and evaluate drug quality.
- Monitor inventory and prevent stock-outs.
- Ensure proper storage conditions and cold-chain management.
- Maintain accurate records for auditing and policy compliance.
