Band 9 Sample Essay: Prevention vs Treatment

Sample Question: "Some people believe that governments should focus primarily on disease prevention rather than treatment, while others argue that both prevention and treatment are equally important for public health. Discuss both views and give your opinion."

Band 9 Sample Response:

"Public health resource allocation represents a fundamental challenge in healthcare policy, requiring evidence-based decisions about investment priorities between disease prevention strategies and curative treatment services while considering population health needs, cost-effectiveness analysis, healthcare system capacity, and equity considerations that influence optimal approaches to maximizing population health outcomes within resource constraints. This debate reflects broader questions about healthcare system design, the role of upstream versus downstream interventions, and the most effective mechanisms for achieving sustainable population health improvement while maintaining healthcare accessibility and quality for all population groups."

"Arguments for prevention priority emphasize the superior cost-effectiveness of upstream interventions, long-term population health benefits, and the potential to address root causes of disease while reducing future treatment demands on healthcare systems. Epidemiological evidence demonstrates that prevention interventions including vaccination programs, health education campaigns, environmental health improvements, and policy changes such as tobacco control can prevent millions of deaths while generating substantial economic returns through reduced treatment costs and productivity improvements. Prevention strategies address social determinants of health including education, income, housing, and environmental quality that create systematic differences in health outcomes, offering opportunities to reduce health inequities while improving overall population health through interventions such as early childhood development programs, workplace safety regulations, and community-based health promotion that create lasting health improvements across multiple generations."

"However, treatment advocates argue that curative services provide essential healthcare access for individuals with existing health conditions while maintaining public confidence in healthcare systems and addressing immediate health needs that prevention cannot eliminate. Even with optimal prevention programs, populations will continue to experience acute illnesses, injuries, chronic diseases, and health emergencies that require high-quality treatment services including emergency care, surgical interventions, disease management, and palliative care that improve quality of life and reduce suffering for affected individuals and families. Treatment services also provide important secondary and tertiary prevention benefits through early detection, disease management, and complication prevention that minimize long-term health impacts while maintaining productivity and quality of life for individuals with chronic conditions, supported by rehabilitation services and community-based care that optimize functional outcomes."

"In my assessment, optimal public health policy requires balanced investment in both prevention and treatment that reflects epidemiological evidence, population health needs, and cost-effectiveness analysis while ensuring comprehensive healthcare system coverage that addresses both upstream health promotion and downstream treatment services. Effective strategies should prioritize high-impact prevention interventions including vaccination, injury prevention, and environmental health protection while maintaining robust treatment capacity for essential services including emergency care, maternal and child health, and chronic disease management, supported by health system integration that links prevention and treatment services through approaches such as preventive care delivery in clinical settings and community health programs that provide both health promotion and early intervention services based on population health assessment and continuous monitoring of health outcomes and system performance."
