Avoiding the sharp end

Written by: Eureka! | Published:

For many, a trip to the doctor or dentist is filled with trepidation, especially when there is any likelihood of a needle being involved. While no one likes having an injection, as many as 10% of the population are reported as having a phobia of needles.

The trouble is that hypodermic needles, and injections generally, are necessary for a variety of medical procedures, meaning patient fears must simply be confronted and overcome. And, as difficult as this can be for adults, young children in particular face a barrage of vaccinations in early life that all need to be administered via a needle.

The challenge

The challenge this month is to come up with an effective alternative for administering drugs and vaccines, which avoids needles altogether. While hypodermic needles have proven extremely effective, there are many shortcomings alongside patient fear.

Drugs administered using needles are in a liquid form, which means their temperature needs to be carefully controlled in a fridge or chiller. For more remote parts of the world where electricity is not available, this creates a significant challenge.

The other obvious challenge is that any procedure using a needle requires a professional. Any solution to the challenge should not only make vaccines easy to administer, but enable them to be self-administered by patients, offering the opportunity to take vaccines in to more remote areas to immunise the population.

Of course, any solution must also be as good as needles, if not better. For this challenge also assume that the drug companies can supply powder, liquid or even vapour drugs – so don’t concern yourself with the pharmaceutical side of things.

We have a solution in mind that we will reveal next month. If you have any ideas either email them to the editor (justin.cunningham@markallengroup.com) or leave your idea below as a comment..
