Effectiveness of Technologies (HSC SSCE Biology): Revision Notes
Effectiveness of Technologies
Understanding technology effectiveness
Technologies in healthcare are designed to help manage the symptoms and effects of various disorders and conditions. Their primary goal is to improve the quality of life for people living with these conditions.
When effective technologies are not available, individuals must cope with their disorder using their own resources. This situation affects not only the person with the condition but also creates challenges for their families and carers. Healthcare and welfare systems face increased pressure because they must provide ongoing support without the benefits that technology can offer.
To determine whether a technology is truly effective, we need to evaluate it using specific criteria. These include:
- The advantages and disadvantages of using the technology
- What is required to use the technology
- The impact on the individual's life if the technology is not available
- How the technology affects quality of life and independence
Case study: Cochlear implants
What is sensorineural hearing loss?
Sensorineural hearing loss is a type of hearing loss caused by damage to the inner ear or the auditory nerve pathways to the brain. This is the type of hearing loss that cochlear implants are designed to treat.
The effectiveness of cochlear implants
Cochlear implants represent a highly effective technology for treating profound deafness. These surgically implanted electronic devices provide a sense of sound to people with severe sensorineural hearing loss.
Before cochlear implants became available, people with profound hearing loss had to rely on alternative communication methods including:
- Sign language
- Lip reading
- Written communication
These alternatives often led to:
- Reduced language skill development, particularly in children born deaf
- Lower quality of life
- Limited ability to participate fully in society
Benefits for children born profoundly deaf
The introduction of cochlear implant technology has transformed outcomes for children with profound hearing loss. Key benefits include:
Early intervention: Infants as young as six months can receive cochlear implants.
Normal development: With proper support and guidance, children with cochlear implants can:
- Develop language skills at a normal rate
- Acquire speech abilities naturally
- Show no developmental delays in hearing, language, or speech
Educational integration: Children with cochlear implants:
- Do not need to attend special schools
- Can be fully integrated into mainstream education
- Can participate equally in society
Benefits for older adults
Adults who have lost most of their residual hearing (remaining hearing ability) can also benefit significantly from cochlear implants. After a period of adjustment and training, they can:
- Hear the sounds of the world around them again
- Experience improved quality of life
- Maintain greater independence
- Contribute positively to their families and communities
- Function without requiring extra assistance
Disadvantages of cochlear implants
Despite their significant benefits, cochlear implants do have some limitations:
Key limitations to consider:
- Surgical procedure: Recipients must undergo an operation to have the device implanted
- Post-operative side effects: As with any surgery, there are potential complications following the procedure
- Ongoing costs: The technology requires regular updates and maintenance
- Programming and training: Users need specialized training to learn how to interpret the sounds they hear through the device
- Limited hearing distance: The device has a restricted range for detecting sounds
Overall assessment
The disadvantages of cochlear implants are far outweighed by the benefits. The ability to:
- Hear naturally
- Develop speech and language normally
- Function as a contributing member of society
- Live without significant disability
These outcomes demonstrate that cochlear implants are a highly effective technology that dramatically improves quality of life.
Evaluating technology effectiveness
When assessing whether a technology designed to assist with a disorder is effective, researchers and healthcare professionals consider multiple factors. A comprehensive evaluation should examine:
Advantages: What benefits does the technology provide? How does it improve quality of life?
Disadvantages: What challenges or limitations does the technology present? What are the costs and side effects?
Requirements for use: What is involved in using the technology? Does it require surgery, training, or ongoing maintenance?
Impact without the technology: How would the individual's life be different if this technology were not available?
Broader impacts: How does the technology affect families, carers, and healthcare systems?
By systematically evaluating these criteria, we can make informed judgments about how effective a technology truly is in managing a disorder.
Remember!
Key Points to Remember:
- Technologies aim to improve quality of life for people with disorders by helping them manage symptoms and effects
- Without effective technologies, individuals, families, and healthcare systems face increased burdens
- Cochlear implants are a highly effective technology that enables people with profound hearing loss to develop normal speech and language skills
- Children fitted with cochlear implants from six months of age can develop normally and integrate fully into mainstream society
- The effectiveness of a technology is evaluated using criteria such as advantages, disadvantages, requirements for use, and impact on quality of life
- Even technologies with some disadvantages can be highly effective if their benefits significantly outweigh the limitations
