Background Heart rate is routinely measured as part of the clinical examination but is rarely acted upon unless it is well outside a population-based normal range. With wearable sensor technologies, heart rate can now be continuously measured, making it possible to accurately identify an individual's "normal" heart rate and potentially important variations in it over time. Our objective is to describe inter-and intra-individual variability in resting heart rate (RHR) collected over the course of two years using a wearable device, studying the variations of resting heart rate as a function of time of year, as well as individuals characteristics like age, sex, average sleep duration, and body mass index (BMI).

Objective:With the rising incidence of health care emergencies, there has been a considerable burden placed on health care systems worldwide. We aimed to determine the willingness and capacity of medical students in Ireland to volunteer during health care emergencies.Methods:An online, cross-sectional survey of medical students at the National University of Ireland was conducted in 2015.Results:Respondents totaling 274 completed the survey (response rate – 30.1%). Of participants, 69.0% were willing to volunteer in the event of a natural disaster and 59.1% in an event of an infectious epidemic, with altruism being the strongest motivational factor. Only a minority of students (23.7%) felt their current skill level would be useful in an emergency setting.Conclusions:Medical students express a strong interest in actively participating during health care emergencies.

BackgroundTo provide the optimum level of healthcare, it is important that the supply of well-trained doctors meets the demand. However, despite many initiatives, Ireland continues to have a shortfall of physicians, which has been projected to persist. Our study aimed to investigate the migration intentions of Irish medical students and identify the factors that influence their decisions in order to design appropriate interventions to sustain the supply of trained doctors in order to maintain a viable medical system.MethodsAn online cross-sectional survey was undertaken of all Irish medical students studying in the Republic of Ireland. The survey included nominal, ordinal, and scale items to determine migration intentions, factors influencing their decisions, and understanding of the Irish healthcare system.ResultsA total of 2 273 medical students responded (37% response rate), of whom 1 519 were classified as Irish medical students (having completed secondary school in Ireland). Of these, 88% indicated they were either definitely migrating or contemplating migrating following graduation or completion of the pre-registration intern year. Forty percent expressed an intention of returning to Ireland within 5 years. The factors most influencing their decision to leave were career opportunities (85%), working conditions (83%), and lifestyle (80%).ConclusionThe migration intentions expressed in this study predict an immediate and severe threat to the sustainability of the Irish healthcare service. Urgent interventions such as providing information about career options and specialty training pathways are required. These must begin in the undergraduate phase and continue in postgraduate training and are needed to retain medical school graduates.
