Hewlett-Packard Co is restructuring its Medical Products Group, consolidating product lines, disbanding groups and cutting 250 jobs from the 5,300 total. It expects costs of restructuring to be incurred in the first and second quarters of 1997, but those costs will not be materially significant, it said. It intends to consolidate its heart defibrillator and electrocardiograph product lines in McMinnville, Oregon into its Resuscitation Division in Andover, Massachusetts, and here, of the 152 employees affected, 100 will be offered new jobs in the Resuscitation Division. The Healthcare Information Management Division in Andover will be disbanded, and most of its products and services will be transferred to other Medical Products Group un its. And the company’s CareVue clinical information systems disappears into the Patient Monitoring Division.
