Standard x Pattern: Qual a diferença?

I granted that It's difficult to decide which of the two above choose to say "padrão" in portuguese, because if, on one hand, you can say "Standards of living" on the other hand, you shouldn't say "Standards of consumption" but you must say "Consumption patterns", so It's really difficult to me to distinguish the usage of both words, as it is for some couple of words on account of wich sometimes I create a topic in this amazing and enriching forum, so here are some examples

'higher standards or patterns of service in hospitals?"

"Patterns or standards of employment in urban areas are different from those in the countryside"

I hope you guys to forgive my ignorance, thank you!
