Community health nurses have the potential to make significant contributions to meet the health care needs of various population groups in a variety of community settings. In order to assess the extent to which CHNs are achieving this potential, WHO conducted a study between 2010 and 2014 that examined the status of community health nursing in 22 countries, 13 of which were experiencing a critical shortage of health care workers. The study revealed that the countries surveyed had the basic and operational framework for optimizing CHN in their health systems as evidenced by the availability of PHC structures to guide interventions. However, challenges were identified related to the education, practice and management of CHNs in these countries. The major challenges identified were: Limited availability of career opportunities; poor worker retention; low recognition for CHNs; inadequate and unsupportive working conditions and environments; absence of educational standards; varying educational entry-level requirements for CHN programmes; and a lack of consensus on the scope of practice for CHNs.
