Question

Please identify a clinical protocol from any source. If you can attach it to your submission as a word document, it is great. If not, summarize your comments on the advantages and disadvantages of the study design and outcome measures. If you have a reference book that describes protocols, you can read it as background material. If you find a good source, mention it in the discussion board for others to use too.

Answer 1

Each study designs have different advantages and disadvantages,For example let us take cross-sectional study designs-It is a type of descriptive,observational study which involves maesuring different cariables in the population of interest at a single point in time.This simultaneous data gathering is often thought of as a snapshot of conditions present at the instant.

Advantages:

• The nature of this study design offers a quick and easy way for an epidemiologist or any kind of researcher to quickly amass dat.While some special care studies do require more specific data for most cross sectional studies.
• It allows for quick and easy data gathering even for a large target population.
• Assessment of outcomes and risk factors for the entire population is also done with little trouble as the sample is a near perfect snapshot of the whole.
• The ease of gathering the needed information translates the cost effectiveness.The low cost involved in cross sectional study make it possible to conduct more thorough investigation of their populations overall condition.

Diasadvantages:

• These study designs fail on the part of confounding factors.
• Additional variables may affect the relationship between the variables of interest but may not affect those variables themselves.Such observations are often lost in cross sectional studies.
