Objectives Podcasts have the potential to facilitate communication about palliative care with researchers, policymakers and the public. Some podcasts about palliative care are available; however, this is not reflected in the academic literature. Further study is needed to evaluate the utility of podcasts to facilitate knowledge-transfer about subjects related to palliative care. The aims of this paper are to (1) describe the development of a palliative care podcast according to international recommendations for podcast quality and (2) conduct an analysis of podcast listenership over a 14-month period.
Methods The podcast was designed according to internationally agreed quality indicators for medical education podcasts. The podcast was published on SoundCloud and was promoted via social media. Data were analysed for frequency of plays and geographical location between January 2015 and February 2016.
Results 20 podcasts were developed which were listened to 3036 times (an average of 217 monthly plays). The Rich Site Summary feed was the most popular way to access the podcast (n=1937; 64%). The mean duration of each podcast was 10 min (range 3–21 min). The podcast was listened to in 68 different countries and was most popular in English-speaking areas, of which the USA (n=1372, 45.2%), UK (n=661, 21.8%) and Canada (n=221, 7.3%) were most common.
Conclusions A palliative care podcast is a method to facilitate palliative care discussion with global audience. Podcasts offer the potential to develop educational content and promote research dissemination. Future work should focus on content development, quality metrics and impact analysis, as this form of digital communication is likely to increase and engage wider society.

Technology is increasingly being integrated into medicine to support new opportunities for the delivery of clinical practice, education and research.1 Podcasts are episodic digital audio recordings that are downloaded through web syndication or streamed online.2 Research demonstrates that podcast listenership is increasing.3–5 The percentage of Americans who have listened to a podcast has increased from 9% to 17% between 2008 and 2015.6 Podcasts are increasingly being used to support medical education.7–10 Palliative care podcasts are available;11 these include ‘Get Palliative Care’ (by the Center to Advance Palliative Care—CAPC),12 the ‘CAPC Palliative Care Podcast’13 and the ‘Hospice of the Bluegrass Podcast’.14 However, there are no published studies about the use of podcasts in palliative care. Podcasts can potentially be used to facilitate communication about palliative care with researchers, policymakers and the public.1 Further study is needed to evaluate the utility of podcasts to facilitate knowledge-transfer about subjects related to palliative care.
The aims of this article are to:
Describe the development of a palliative care podcast according to international recommendations for podcast quality.
To analyse the listenership of the podcast over a 14-month period.
The development of the podcast involved defining the scope and focus of the podcast; developing an infrastructure; identifying quality indicators of podcast quality; designing content; coordinating dissemination and analysing data.
Scope and focus
The podcast was aimed at healthcare professionals with an interest in palliative care, technology and innovation. The podcast method was chosen for its effectiveness, popularity and accessibility.7
A portable audio recorder and microphone (total cost=£50) was purchased with funds from an educational grant. SoundCloud, a popular audio streaming website, was chosen to host the podcast (https://soundcloud.com/mypal). The website was accessible online and also has native applications for mobile devices (Android and iOS). An online blog was developed for the podcast (http://amaranwosu.com/amipal/) to facilitate dissemination and provide links to references presented in the podcast.
Quality indicators for medical education podcasts and blogs have been developed.15 These indicators were developed using a modified Delphi consensus of international healthcare professional educators. The indicators with ≥90% consensus (table 1) consist of 13 items (10 of which are relevant to podcasts) within themes that include: content, credibility, bias, transparency, academic rigour, functionality, use of resources, orientation and professionalism. These quality indicators were used to inform the podcast development.
The podcast was named AmiPal (previously MyPal), reflecting the name of the corresponding author and subject of Palliative Care. The format involved interviews, opinion pieces and education-focused content. The topics covered are presented in table 2. Podcasts were edited using Audacity (http://www.audacityteam.org), a free open-source, cross-platform audio-editing tool.
The podcasts were released episodically under the ‘Science and Medicine’ category on the SoundCloud website. The podcast's Rich Site Summary (RSS) feed was registered with podcast repositories, including iTunes (http://www.apple.com/itunes), Stitcher (https://www.stitcher.com), TuneIn (http://tunein.com) and Acast (https://www.acast.com). The RSS feed enabled users to access the podcast via a computer or mobile device. Each episode was promoted on social media using palliative medicine hashtags.16 Widgets (stand-alone embeddable web applications) were embedded into the blog and social media posts, which enabled the podcasts to be directly played.
Analysis and feedback
Feedback to each episode was possible using email communication and social media. Additionally, healthcare professionals (in Merseyside, UK) were contacted by email and were encouraged to provide feedback. The listenership analysis was conducted using the SoundCloud analytics tools. Data were analysed for frequency of plays and geographical location.
Twenty podcasts were developed between January 2015 and February 2016. The cumulative total of podcast plays was 3036, an average of 217 monthly plays (table 3 and figure 1). The RSS feed was the most popular way to access the podcast (n=1937; 64%). Between January and September 2015, the podcast was most accessed via the SoundCloud website. However, from October 2015, the cumulative RSS feed plays were higher. The mean duration of each podcast was 10 min (range 3–21 min). The podcast was listened to in 68 different countries (table 4) and was most popular in English-speaking areas; specifically, the USA (n=1372, 45.2%), UK (n=661, 21.8%) and Canada (n=221, 7.3%).
A small amount of feedback was received (10 responses); overall, this was positive. The podcast was modified in response to the feedback with changes to the audio quality, style and format. Specifically, the podcast length shortened to <6 min (evident from the last six podcasts) and backing music was added to improve the rhythmic flow of the audio.
This analysis demonstrated that the AmiPal palliative care podcast had a wide geographical reach with the majority of listeners originating from Western English-speaking countries.
Strengths and uniqueness of this study
This is the first study that describes the development and analysis of a palliative care podcast that was developed according to relevant quality indicators. The podcast was free and accessible across a range of computer and mobile platforms.9 The data of the geographical reach of the podcast provide evidence of the potential of this medium to facilitate international dissemination.
Comparison with previous work
Previous studies have highlighted potential to use technology to inform education and dissemination in palliative care.1 This study adds to evidence from other work, which have used podcasts in medical education.8 ,10 ,17 The podcasts were accessed and played several months after release, which may suggest that new listeners were acquired over-time, and/or the archive was used ‘on-demand’. These findings are consistent with previous work, which reports how podcasts provide a repository of information that can be continually accessed.2 ,18 The majority of podcasts (64%) were accessed via the RSS feed, which may suggest the use of mobile devices. This finding is consistent with the findings of USA and UK research, which demonstrates that two-thirds of podcasts are accessed on a mobile device rather than a computer.4 ,19 The podcast listenership was similar to the CAPC podcast, which (at the time of writing) has a total of 3831 listens from its 12 episodes over the past 24 months. In 2015, CAPC's public facing ‘Get Palliative Care’ podcast series obtained 14 318 listens from 10 podcasts about the patient journey. This highlights the potential interest for podcasts reporting the patient narrative.
The lack of plays from the RSS feed in the first 4 months was due to a delay in the RSS feed being available. Consequently, the potential reach of the podcast in these months was lower. It is likely that the overall proportion of RSS feed plays would have been higher, if the RSS feed was available for the entire period. It is likely that the majority of the RSS feed plays were from mobile devices; however, we cannot ascertain the exact number (as the RSS feed may have been accessed by computer). Furthermore, it is not possible to know whether users listened to the entire podcast or not. Although the podcast was available across a range of computer and mobile devices, there may be some technological challenges to accessing the podcast in some healthcare organisations and resource-poor settings (eg, old internet browsers, web-filtering issues, wireless internet coverage).
Very little feedback was received through the email and social media feedback options. A possible explanation, presented by experts in medical education, may be that the listeners did not place importance on interacting with the podcast host.15 Listeners may personally reflect on the podcast topics without feeling the need to communicate their reflections with the host. Consequently, it is not possible to determine if listeners found the podcasts beneficial. Furthermore, our knowledge of the listenership is relatively unknown, as listeners were not required to provide information or login to access content.
Implications to practice
It is possible to develop a palliative care podcast that has a global reach. Audio recording equipment is available for relatively low cost,20 and many mobile devices contain microphones to record audio.21 Audio hosting sites (eg, SoundCloud.com, Podomatic.com) and open-source audio editing software are freely available (eg, Audacity).20 ,21 Individuals and organisations planning on developing their own podcasts can use quality indicators15 ,22 to develop content and social media to enhance dissemination.16 ,20 If wide dissemination of the podcast is intended, the RSS feed should be registered with podcast databases and social media should be used for promotion.
Future opportunities and research possibilities
Organisations may consider developing podcasts for specific purposes, such as education, lecture capture and research dissemination. Future studies are needed to determine whether palliative care podcasts can facilitate learning for professionals and lay people. Further work can examine the demographics of listeners (eg, using analytics software and surveys) and evaluate learning outcomes of podcasts using of pre and post assessments; this will help to plan priorities for content, quality and to evaluate the impact (eg, for learning and clinical practice) of podcasts. Developed content can be incorporated within the dissemination strategy of institutions, in order to meet learning styles of listeners. Future work can also consider the needs of individuals with hearing deficits (eg, via subtitle video).
Podcasts can be used to facilitate palliative care discussion with a global audience. Podcasts offer the potential to develop educational content and promote research dissemination. Future studies should focus on information development, quality metrics and impact analysis of educational podcasts, as this form of digital communication is likely to increase and engage wider society.
