The ever-growing penetration of internet and mobile technologies into society suggests that people will increasingly use web searches to seek health-related information, including advice on first aid in medical emergencies. When a bystander is incompetent in first aid and has no immediate support from Emergency Medical Services (EMS), as it happens in low-resource settings or in disasters, instructions found online could be the sole driver for administering first aid before arrival of professional help.

The aim of this study was to evaluate quality of advice on first aid generated by a web search engine’s question-answering system (QAS) in response to search queries concerning provision of help in common health emergencies.

In December 2022-January 2023, an English-language search was carried out in Google with ten queries based on the keyword combinations (what to do OR how to help) AND (bleeding OR chest pain OR choking OR not breathing OR seizure). The search engine’s QAS responses (up to 11 per search query) were evaluated for compliance with the International Federation of Red Cross First Aid Guidelines 2020 using the pre-developed checklists.

Out of 98 QAS items generated by Google, 67.3% (n = 66) were excluded, mainly because the QAS answers did not address original queries. Eligible unique QAS responses (n = 27) showed poor coverage of the guideline-compliant instructions on first aid. Mean percentage of QAS responses providing a first aid instruction with complete adherence to the guidelines varied from 0.0 for choking to 19.5 for seizure. Only three (11.1%) QAS responses contained an explicit instruction to access EMS, while 66.7% (n = 18) included directions either contradictory to the guidelines and potentially harmful (eg, use of home remedies in chest pain) or inapplicable for an untrained person (eg, use of tourniquet in bleeding).

Although the search engine’s QAS responds to user’s inquiries concerning assistance in health emergencies, the QAS-generated answers, as a rule, omit potentially life-saving evidence-based instructions on first aid and oftentimes give advices noncompliant with current guidelines or inadequate for untrained people, and thus create risks for causing harm to a victim.

Bystanders can improve the outcome in emergencies by activating the “chain of survival.” Gaza’s (Palestine) population has little, if any, access to training in Basic Life Support (BLS) and cardiopulmonary resuscitation (CPR). The goal was to recruit local medical students to be life-saving first aid instructors, and have them train 3,000 laypeople in BLS and CPR.

One hundred and seventeen medical students from Al Azhar University-Gaza (Gaza City, Palestine) were trained as BLS and CPR instructors. Twelve training hours were delivered in practical BLS and CPR skills, plus four in communication and didactical skills, to enable training of laypeople. Students answered a questionnaire exploring demographics, prior training experience, expectations, and motivation to join the training. Teaching material were developed after the European Resuscitation Council (ERC; Niel, Belgium) guidelines and similar training at The Arctic University of Norway (Tromsø, Norway).

A total of 117 medical students (52.1% female; 47.9% male), from third through sixth year, completed training, and all were in their early twenties. Ninety-five (81.2%) agreed to answer the questionnaire. Of those, five students lost family members during Israeli military operations. Eighty-two (70.1%) never had hands-on first aid training. Seventy-six (80.0%) hoped the training would improve their community’s response to emergencies. With 58 training sessions completed, 1,312 laypeople (596 males; 716 females) were trained: 5.52 lay trainees per student instructor. The majority (n = 1,012; 77.1%) were school students aged 13–20 years.

It is feasible to recruit local medical students for practical BLS and CPR trainings targeting laypeople in communities under stress. The training impact on local resilience and patients’ outcomes need further studies.
