FEV1 <80% of predicted, and FEV1/FVC ration <0.70
What is the FIB-4 index?
Advanced liver fibrosis:
Low albumin and
FIB-4 = (age x AST) / (plt x ALT^1/2)
Score <1.45 has a negative predictive value of 90%
Good for avoiding biopsy, should be evaluated with transient elastography to confirm cirrhosis.

Should I give O2 to a patient with MI?
Evidence does not support supplemental O2 unless O2 sat drops below 90% or are in respiratory distress.
Feeding tube for advanced dementia?
No, alter food texture or offer small portions, high calorie supplements may promote weight gain, but non improve function or survival.
Tube feeding increases risks associated with placement, chemical/physical restraints, tube blockages and dislodgements = increased ED visits and no clear benefits.
What are the benefits of exercise?
Does it substantially increase weight loss?
Exercise improves insulin and glycemic control in diabetes, improves blood pressure, reduces CVD risks, and maintains weight loss.
Only moderately beneficial for promoting weight loss, including when added to diet.
When and how to treat for fracture risk?
Osteoporosis = T-score of -2.5 or less Osteopenia = T-score -1 to -2.5 and probability of hip fracture at least 3% on FRAX

- Effectiveness - providing health care services likely to benefit while avoiding those not likely to benefit
- Efficiency - avoiding waste
- Safety - avoiding harm
- Timeliness - avoiding unnecessary waiting and harmful delays
- Equity - care that does not vary regardless of gender, ethnicity, geographic location, SES
- Patient-centered care - respecting individual patient values
