Santa Ana-based PacifiCare Health Systems Inc.’s first-quarter profit fell 4.9%, less than expected, as the managed-care company began to get a handle on rising medical costs. Net income fell to $41.3 million, or 90 cents a diluted share, from $43.4 million, or $1.12, a year earlier. The results beat the 73-cent average estimate of analysts.
