Study limitations
Due to the fluid nature of the current COVID-19 crisis, many aspects of
clinical care and education vary from day to day and also regionally
within the North American AHNS training programs. In addition, due to
the nature of survey collection, reporting bias is possible and
operative log data may be inaccurate due to delays in entry or omissions
by the current and past fellows. Efforts were made to interpret the best
available data and to proactively make educational changes thought to
enhance the current experience. Follow-up assessment will be needed to
evaluate the effectiveness of these interventions.
