ahh yes, I'd missed the database calls...
What are the fields your database returns? Your hash does look ok, but I would probably put the AM0 AM1 etc in an array, not a hash... something like...
for $key (keys %$c) {
  next unless $key =~ /^[AP]M_\d+$/;
  push @{$a_record{$c->{ANA_ID}}{Dates}{$c->{ACTION_DATE}}},
          $c->{$key} if $c->{$key};
}

Not tested, but should work... that should go through the keys, matching any that start with AM or PM with an _ and the a number, and push them into an anonymous array if they have a value... this is assuming AM_0 AM_1 etc just hold a 1 or 0 for a yes or no... }
