Public knowledge of how to use an automatic external defibrillator in out-of-hospital cardiac arrest in Hong Kong

Regular dental attendance and periodontal health knowledge: A cross‐sectional survey

“…In an attempt to quantify the impact of this shortcoming, the precision of the study was recalculated for an infinite population resulting in an actual precision error of 1.42% in the estimation of a proportion by an asymptotic 95% bilateral confidence interval, assuming an expected proportion of 28%. Another matter of concern could be the apparently limited response rate achieved (43.3%), which is within the range reported in studies using a similar approach (28% in the UK (Rogers et al., ) in 2008, 30% in Australia (Campbell et al, ) in 2009 or 50% in Hong Kong (Fan et al, ) in 2015). Unfortunately, hypothetical socio‐demographic differences between respondents and non‐respondents could not be explored.…”

“…For a diagnosis to be made, the patient has to demand consultation with a clinician but only symptoms perceived as atypical would be a matter of concern. Thus, vague, unspecific indicators common to a large proportion of individuals-less than 20% Spaniards elder than 35 have a healthy periodontium (Bravo Pérez et al, 2016)-and which are typical of early periodontal disorders (Dye, 2012), may not worry the patient until disease progression is evidenced through more serious manifestations. In this situation, the desirable early periodontal treatment (Slots, 2013) depends on the recognition of the initial symptoms of the disease, a circumstance that does not seem to occur in large groups of the world population (Varela-Centelles et al, 2016).…”

Public access defibrillation in Hong Kong in 2017

“…According to a recently published survey, only 18% of respondents would use an AED in an OHCA and approximately 77% had no knowledge of the location of an AED near their home or workplace. 22 These findings probably explain the very low rate of bystander defibrillation (1.4%) in OHCA in Hong Kong. 1 Simply increasing the number of AEDs installed without more extensive engagement of the public is bound to fail.…”

“…Fear of legal liability because a lack of Good Samaritan legislation is sometimes quoted as a reason for not providing help to the needy. 22 Factors related to the AED itself may also be a concern. A survey on the functional status of public AEDs by Haskell et al 23 identified problems such as battery expiry, inaccessibility, and invisibility of the AED.…”

Public access defibrillation: the road ahead

“…A local study showed that public knowledge about AEDs was inadequate and fewer than 20% of respondents to a survey would use one. 6 The lack of enactment of a Good Samaritan law may not reassure members of the public about possible liability when using an AED, even though they are designed to be operated by a layperson. On 1 October 2017, Mainland China enacted this law under Cap 184 of the Civil Law of the People's Republic of China.…”
