www.gloucesterrugbyclub.com Ryan said: "We did not have the field position in the second half that we had in the first.
"We got a good platform and we had the game in our control by half-time. It was a bit disappointing that we didn't kick on from that. But it was all about getting our basics right, that was the important thing."
Ryan and director of rugby Nigel Melville are likely to be boosted by the return of England wing James Simpson-Daniel for next week's Premiership clash against Harlequins following his recovery after shoulder surgery.
Looking back at the match Melville added: "It was a stop start game and very messy, especially in the second half. There was just no flow."
Andy Hazell limped off with a leg injury during the second half, and Melville said that he'd know more after the injury had been assessed on Sunday.
Worcester, meanwhile, remain just one point above basement club Quins, and they will now prepare for a crucial home game against Leeds next Friday.
"Overall, we are very disappointed. We didn't play well and we just lacked composure at vital times," said Worcester rugby director John Brain.
"But our destiny is still in our own hands; we have got to secure some home wins, starting with Leeds on Friday night.
"If we were to win three more matches then that would probably be job done. But we have to take it one step at a time - and we know that we can take a big step forward if we secure the win on Friday."
