Why It Matters: CRDs are chronic conditions that require continuous management to prevent exacerbations and hospitalizations. The global burden of CRDs is expected to rise due to aging populations, increased tobacco use, and worsening air quality. Healthcare professionals play a vital role in managing CRDs through early diagnosis, patient education, and ensuring adherence to medication and lifestyle changes.

Key Recommendations for Healthcare Professionals:

Implement spirometry testing for early diagnosis of COPD and asthma.

Encourage smoking cessation programs and educate patients about the dangers of tobacco use.

Prescribe appropriate bronchodilators and corticosteroids for disease management.

Advocate for cleaner air policies to reduce environmental risk factors.

5. Mental Health Disorders

Mental health disorders, including depression, anxiety, bipolar disorder, and schizophrenia, affect an estimated 1 in 4 people globally at some point in their lives. Depression alone is the leading cause of disability worldwide, according to WHO.

Why It Matters: Mental health disorders often go undiagnosed or untreated due to stigma, lack of awareness, and limited access to mental health services. Untreated mental health conditions can lead to a decline in quality of life, increased healthcare costs, and even premature death due to suicide. Healthcare professionals must prioritize mental health by integrating mental health services into primary care settings and advocating for policy changes that improve access to care.

Key Recommendations for Healthcare Professionals:

Conduct regular mental health screenings during routine patient visits.

Develop a collaborative care model involving psychologists, psychiatrists, and social workers.

Promote community-based mental health programs to reduce stigma and improve access to care.
