We support our academic partners to independently study the benefits GoodSAM can bring.
It is vital to remember that they are studying GoodSAM solutions, not WhatsApp, Zoom or
Skype. Our video systems are designed for emergency use and our cardiac system is a
highly governed system and so the results do not translate to general video systems or
those trying to copy us. Indeed, where other systems have been used, they have often failed.
With that in mind we have divided the publications into video focused and cardiac focused:
- Instant-On-Scene Video Publications (by Ambulance and Police)
- GoodSAM Cardiac Alerting Publications
Live video from bystanders' smartphones to medical dispatchers in real emergencies
Linderoth et al, BMC Emergency Medicine Nov 2021
This study analysed 838 emergency GoodSAM Instant-On-Scene Videos. Key findings:
- 838 emergency videos
- GoodSAM video changed assessment of the patient's condition in 51.1% of calls - 12.9% more critical, 38.2% less critical
- GoodSAM video altered emergency response in 27.5% of cases
- Quality of care (e.g. CPR or airway) improved in 28.4% of calls with GoodSAM Video
- 97.3% of callers felt live video should be implemented.

Live video streaming from bystander's smartphone in out-of-hospital cardiac arrest
Linderoth et al Resuscitation 168 P35-43 Nov 2021
CPR was provided with live video in 51 OHCA. Video guided CPR improved CPR quality:
- Hand position (incorrect in 36 cases, improving in 23 (60.5% OR 5.8)
- Compression rate (incorrect in 35 cases, improved in 26 (75% OR 7.7)
- Compression depth (incorrect in 54 cases, improved in 32 (58% OR 7.1)

Study of prehospital video telehealth for callers with mental health-related complaints
Nehme et al 2022
This study by the team at Ambulance Victoria completed 738 video consultations for non-urgent mental
health concerns. They demonstrated GoodSAM video resulted in fewer emergency ambulance dispatches
compared with voice-only triage with increased referral to alternative/more appropriate services.

Video Consultation Pilot within an NHS 111 Service Clinical Assessment Service (CAS)
NHS Digital Evaluation Report
This report evaluated GoodSAM video in North West Ambulance Service 111 Centre
Key Findings:
- In 93% of calls, an outcome was reached more quickly with GoodSAM video.
- 17% of calls were upgraded.
- 24% of calls were downgraded.
- 96% of dispatchers said it increased their confidence in clinical decision making.
- In 62% of cases it prevented the onward need for a face to face consultation.
- And >97% found the GoodSAM system easy to use.
- Call times were reduced from 15 minutes to 6 minutes.

Video triage of children with respiratory symptoms at a medical helpline is safe
and feasible - a prospective quality improvement study.
PLOS ONE April 2023
Key Findings:
This study compared video and telephone triage of 617 paediatric patients with respiratory tract
infections with fewer video-triaged patients needing assessment at hospital (39% vs 46% p=0.07).
The technique was highly feasible and acceptable with no adverse events registered.

Rapid Video Responses (RVR) vs Face to Face Responses by Police Officers to Domestic
Abuse Victims: a Randomised Controlled Trial
Rothwell et al Cambridge Journal of Evidence-Based Policing May 2022
This study of 560 domestic violence victims found that, compared to standard follow up,
GoodSAM video resulted in:
- 656 times faster response to victims (3mins vs 1969 mins)
- Higher victim satisfaction (89% vs 78%)
- A 50% higher arrest rate (24% vs 16%)
- Improves Trust and confidence in the police

Providing evidence of benefit in terms of lives saved requires a comprehensive cardiac registry and ambulance services to follow up survivors. When done, odds ratio of survival with a GoodSAM response has been found to be 3 times greater (see below). Ambulance Victoria report 54 survivors from GoodSAM intervention and there are many survivor stories.
The Effect of the GoodSAM volunteer first-responder app on survival to hospital discharge following out-of-hospital cardiac arrest
Smith et al European Heart Journal: Acute Cardiovascular Care (2021), 00, 1-12
Key findings:
- Being attended by a GoodSAM Responder increased Odds ratio for survival to hospital discharge by
- 3.15 in East Midlands and
- 3.19 in London
* Reported acceptance rates were low (1-5%) however, this is 2016 data and responder density and acceptance is considerably higher now (> 15%).

A binational survey of smartphone activated volunteer responders for out-of-hospital cardiac arrest: Availability, interventions, and post-traumatic stress
Haskins et al, Resuscitation 169 65-75 2001
Brian Haskins
This web based survey of 1985 responders found that 38% accepted alerts, 27% arrived on scene and 14% provided patient care.
One responder screened positive for PTSD attributing events at and outside of work with also the smartphone alert contributing.

Micro-volunteering at scale can help health systems respond to emergencies, such as the Covid-19 pandemic
Churchill 2020
This case study by Neil Churchill OBE describes the deployment of GoodSAM in partnership with NHSE and the Royal Voluntary
Service during Covid to recruit and manage 800,000 NHS Volunteers. This was the first scaled roll out of micro-volunteering.

Micro-volunteering: Report of an Evaluation
The Health Innovation Network
This is a comprehensive report of micro-volunteering during the Covid Pandemic. It should be noted
that GoodSAM was working in partnership with NHSE and RVS and hence the actual specification / delivery
of some aspects were at their direction.
