The committee came to the following conclusions:   

• The initial standards-setting process developed by NASA is carefully-designed, evidence-based and involves input from relevant stakeholders ; 
• The process follows an occupational health model as recommended in several prior IOM reports; and,
• It provides an analytical framework for enhancing the safety of human space flight.

The committee recommended the following enhancements to the process: 

• Expanding the opportunity for input and review;
• Strengthening the evidence review;
• Increasing research and validation efforts;
• Enhancing the updates, appeals, and the development of new standards;  and,
• Using an integrated systems approach.
