Background

A modern hospital is a complex,multidisciplinary system which consumesthousands of items for delivery of medicalcare

All these products consumed in the hospitalleave some unusable leftovers

UBC Hospital commissioned a study toanalyze their waste

An 86.6kg sample was collected and handsorted into 24 waste categories (biomedicalwaste not considered)

UBC Hospital waste study

Findings:

1. Composting has thepotential to reduce 41.4% ofwaste

Compostable organics (23.4%): fruitpeels, food scraps and used coffeegrounds

Paper towels (18%): from washroomsand other major hand washing areas

1. Recyclables: plastics(10.8%) and paper (11.2%)

2. Non-recyclable plasticcomprised 0.9% of thewaste stream and garbage

bags comprised 3.8%.3. Medical waste 13.8% .

General waste

Largely composed of domestic orhousehold type waste.

It is non-hazardous to human beings

e.g. kitchen waste, packaging materialpaper, wrappers, plastics

Encourage composting and recycling!

Biomedical waste

Types of waste:

Human anatomical waste

Animal

Microbiology lab

Human blood and body fuild

Sharps

Characterized as:

Biohazardous

Waste that is known or suspected to containinfectious material because of its physical orbiological nature may be harmful to humans,

Biomedical wastemanagementReduction of waste material

Segregated by type and disposed not in thegeneral waste stream

Properly packaged before point of disposalColor-coded and labeled to ensure wastes

are properly handled and disposed

Safely transported within the facilityStorage area before disposal

Biomedical waste

WHMIS standards are not applied to wastematerials but workers need training onhandling and disposing of these wastes

Workers should be properly vaccinated

Hospitals have occupational health and safetypolicies and procedures for accidentalexposures

Treatment and disposal methods arealready outlined in previous lecture notes

Transportation must meet with the TDGRegulations mentioned in the guest lecture

Sharps

Defined as: Waste sharps that are capableof causing punctures or cuts to personhandling it (BC Laws, 2009)

Needles

Syringes

Blades

Laboratory glass

On average, there are 192 injuries per dayfrom sharps in the Canadian healthcaresystem (Becton, Dickinson and Company,2005)

Radioactive waste

Radioactive material used for the diagnosis andtreatment of disease

Two types: sealed sources and unsealed sources.

Sealed sources, usually with long half lives, cannot be accessed as

they are sealed in a capsule or are behind a bonded cover.

Unsealed sources, usually with short half lives, are physically

accessible and are administered to patients, used in research or

testing procedures.

A trained Radiation Officer is responsible for recordkeeping and for the safe use of radio active sources.

The officer ensures instruments are calibrated for

making accurate dose rates and to ensure that the

source is not contaminated.

Radioactive waste

The Atomic Energy Control Board regulates the handlingand disposal of radioactive wastes.

Hospitals have secure on site lead shielded areas where

radioactive isotopes are kept until they are needed or

have decayed to clean waste.

Sealed sources are used many times before being considered as

waste. They are then sent back to the supplier or to another

approved receiver.

Unsealed waste with short half lives, are disposed of as generalwaste after the source has decayed.

All other materials that have come into contact with

radioactive materials, such as towels, gloves, containers,

sharps, are collected together and stored until the

residue has decayed and the items are then disposed of
