Public perception and willingness towards bystander cardiopulmonary resuscitation (CPR) training and performance in Pakistan

Background/Aim: Bystander cardiopulmonary resuscitation (CPR) during out of-hospital cardiac arrest increases both survival rates and neurological recovery, but in Pakistan, an alarmingly low 2.3 % of these individuals receive bystander CPR. This study was designed to identify the reasons that affect the perception and willingness of the public toward bystander CPR training and performance in Lahore, Pakistan. Methods: A CPR master trainer from the USA visited various organisations from 1 December 2022 to 31 January 2023, to conduct training sessions. Before and after the training, a questionnaire was distributed among respondents to fill in. The subjects were asked to answer questions about their perception and willingness to perform bystander CPR. Results: Out of 401 participants, 240 completed the survey, with a response rate of 59.85 %. The majority of them were males [146 (60.8 %)], 215 (89.6 %) were below the age of 40, 107 (44.6 %) were graduated, 182 (75.8 %) never participated in any CPR training, mainly due to their ignorance towards the importance of bystander CPR (52.8 %) and 152 (63.3 %) were eager to participate in the CPR training course. Furthermore, the leading problem in providing bystander CPR was lack of technique or fear of possible harm that can be proved fatal (48.8 %), followed by concerns related to involvement in any legal procedure (10.0 %). Conclusions: Bystander CPR is still uncommon in Pakistan. Participants were reluctant to perform bystander CPR because of various concerns and fears. Lack of proper skill and causing additional harm were the main reasons associated with this. Hence, while improving CPR training and public education, these findings must be considered

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
