High-risk patients refer to individuals who have an increased likelihood of experiencing adverse health outcomes or complications due to various factors such as pre-existing medical conditions, advanced age, lifestyle choices, or genetic predispositions. These patients may require more intensive monitoring, specialized care, and targeted interventions to prevent or manage potential complications. Research in the area of high-risk patients focuses on identifying risk factors, developing effective screening and assessment tools, implementing evidence-based interventions, and evaluating outcomes to improve the quality of care and outcomes for these vulnerable populations. By understanding and addressing the unique needs of high-risk patients, healthcare providers can better tailor their treatment plans and support services to optimize patient outcomes and reduce healthcare costs.
