Insights
Pre-recorded heart sound referrals for pediatric heart murmurs are not cost-saving in Troms. The current patient volume is too low to justify the investment in telemedicine technology.
Area of Science:
- Medical technology assessment
- Pediatric cardiology
- Health economics
Context:
- Remote consultations via telemedicine can reduce travel burdens for children and parents.
- 41 clinics in North Norway have adopted sound recording equipment for electronic referrals.
- General practitioners (GPs) can record heart sounds locally for specialist review.
Purpose:
- To evaluate the cost-effectiveness of using pre-recorded heart sound telemedicine referrals.
- To determine if the investment in telemedicine equipment is a cost-saving technology for pediatric heart murmur referrals.
Summary:
- A cost analysis compared pre-recorded telemedicine referrals with traditional patient travel to a secondary care center.
- The study found pre-recorded heart sound referrals to be 216,000 NOK more expensive annually.
- Break-even requires over 195 pediatric heart murmur referrals per year (1.7 per GP).
Impact:
- The current volume of pediatric heart murmur cases in Troms is insufficient to make telemedicine a cost-saving strategy.
- The findings suggest that widespread adoption of this technology may not be economically viable in low-volume settings.
- Further analysis may be needed to explore optimal implementation strategies for telemedicine in specialized pediatric care.
Background:
The use of pre-recorded heart murmur in an electronic referral for a remote consultation can save children and their parents from having to travel to the nearest out-patient clinic. The heart sound can be recorded by the GP at the local health clinic and sent by e-mail to the specialist. 41 clinics in the North Norway healt region have invested in equipment that makes pre-recorded sound referrals possible. This study analyses whether this investment is a cost-saving technology or not.
Methods:
A yearly average of 50 children with a heart murmur are referred to a specialist in Troms. The costs of using pre-recorded telemedicine were compared to the costs of patient travelling to the nearest secondary care centre.
Results:
Pre-recorded heart sound referrals cost from 216 000 NOK more per year than the alternative of bringing patients to the out-patient clinic. The number of children with a heart murmur needed in order to break even must exceed 195 per year, i.e. 1.7 children per GP per year.
Interpretation:
The number of children with a heart murmur in Troms is too low for this method to be a cost-saving approach.

Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...
