Podcasts for the Delivery of Medical Education and Remote Learning.

Podcasts are increasingly being recognized as an effective platform to facilitate the continuous professional development (CPD) of health care professionals (HCPs). Compared with face-to-face meetings and other more traditional forms of CPD, podcasts allow for flexible learning and are less expensive to develop. Podcasts are at the cutting edge of digital education and can be an important element of a pharmaceutical company's multichannel communications plan to improve HCP engagement and CPD in specific therapy areas. However, developing a successful podcast can have significant challenges. In this viewpoint paper, we provide our perspectives on medical podcasts as a medium for educating HCPs in the digital age. We describe our experience in developing an HIV-focused podcast for Australian HCPs, creating a series that has now expanded to other therapy areas in several countries. Practical considerations and unique challenges associated with industry-sponsored podcasts are outlined. Overall, we believe that the process of developing a podcast can be a challenging but rewarding experience, and CPD delivered via podcasting should be more routinely considered by pharmaceutical companies.

Propofol use precludes prescription of estimated nitrogen requirements.

The objective was to determine whether reducing enteral nutrition to accommodate 1% Propofol-derived energy results in suboptimal nitrogen prescription. This was a prospective observational study of 85 consecutive patients requiring mechanical ventilation and receiving 1% Propofol. Enteral nutrition prescription often failed to meet nitrogen requirements (<90%, in 50.6%; <80%, in 21.1%), whereas fat provided 51% of total energy input, exceeding 2 g fat/kg/d in 20%. However, gastroparesis was common, resulting in suboptimal nutrition (median of requirements: energy 71%; nitrogen 57%). If energy balance had been strictly maintained, substituting 1% with 2% Propofol would reduce the number of patients failing to meet nitrogen requirements (1% vs 2%: <90%: in 58.8% vs 17.6%, P< .001; <80% in 35.3% vs 4.7%, P< .014). These effects are directly related to the amount of fat delivered with Propofol. Intensive care unit-associated gastroparesis commonly reduces enteral nutrition input. However, even where this is overcome, use of 1% Propofol frequently precludes prescription of estimated nitrogen requirements; either 2% Propofol or a non-Propofol alternative should be considered.
