Morbidity and Screening Procedures
Need assistance with the following along with a reference:
- Suggest how understanding the course of a disease can be used to better measure and interpret morbidity. Provide specific examples to support your response.
- Analyze various sources of morbidity data and how morbidity can be measured using incidence and prevalence statistics, and make at least one recommendation for improvement. Provide specific examples to support your response.
"Screening": Need assistance with the following: In 225 words and a reference
- Screening is one approach used by epidemiologists to identify and detect disease. Assess one screening method used in epidemiology, and highlight the advantages and disadvantages of this method. Provide specific examples to support your response.
- Screening is typically done before symptoms occur in contrast to diagnostics testing, which takes place after disease symptoms have been manifested in the patient(s). Diagnostic testing often requires expensive, specialized equipment that is more time consuming, and may involve more pain, discomfort, or risks. Evaluate the pros and cons of screening and diagnostic testing, and make recommendations for the best possible blend of the two (or for the exclusive use of one). Explain your rationale.
