Chapter 3: Community Care & Public Health Nursing Roles

Community Care & Public Health Nursing Roles details the specialized roles of community health nurses and home health nurses, outlining how these professionals utilize a population health approach to address the broad determinants of health, such as socioeconomic status, gender, and environmental factors. National governance through the Public Health Agency of Canada (PHAC) provides the framework for protecting citizens, while discipline-specific core competencies ensure high standards of practice. The text delves into the scientific foundations of community nursing, including health economics, demography, and epidemiology. By understanding the epidemiological triangle of agent, host, and environment, and tracking morbidity through incidence and prevalence rates, nurses can effectively target health interventions. A significant portion of the discussion focuses on the three levels of preventive care: primary prevention to enhance general health through education and immunization; secondary prevention for early disease detection via screening programs; and tertiary prevention to manage existing conditions and prevent further disability. The community nursing process—consisting of assessment, diagnosis, planning, implementation, and evaluation—is presented as a systematic way to improve population outcomes, utilizing tools like community asset mapping and walking surveys. Special attention is given to the practicalities of home visiting, including patient referral criteria, nurse safety protocols, and rigorous infection control measures like hand hygiene. Furthermore, the chapter highlights the growing importance of digital and telephonic support systems, such as telehealth and telephone triage, which empower families to manage health issues from home and reduce unnecessary emergency department visits. By integrating clinical expertise with a deep awareness of vulnerable populations, including homeless families and new immigrants, nurses in the community play a pivotal role in ensuring equitable health outcomes for mothers and children across Canada.
