Healthcare systems globally are struggling to meet the demands of the populations they serve. One of the major problems is the current shortage of trained nurses.

Possible reasons include low nursing school enrollment due to poor perceptions of nursing as a fairly rewarded career and nurses leaving the profession before retirement age due to job dissatisfaction.
