When riots erupted in South Central Los Angeles on April 29, 1992, and ambulances began screaming into nearby emergency rooms,
one of the physicians who responded was Dr. John Halamka, now CIO of Harvard Medical School and a keynote speaker at our SOA
Executive Forum next month.
During those four fateful days, some 60 people were killed and hundreds more wounded — many of whom were treated at Harbor-UCLA
Medical Center, where Dr. Halamka was a young resident. Although he doesn’t remember the exact sequence of events, Dr. Halamka
does recall working nonstop, without food or water, for 36 hours before feeling a sharp pain in his back. Dehydration had
caused a painful kidney stone to form in his urinary tract.
“If anything trains you to be a CIO, it’s being an emergency-care doctor during a riot,” Dr. Halamka jokes. “The triage and
minute-by-minute decisions you need to run a large IT organization are easy compared to dealing with burns, stabbings, and
gunshot wounds.”
As CIO of the school and associated hospitals, Dr. Halamka is responsible for information systems that help 30,000 health-care
workers treat 2 million patients per year. He also helped spearhead MA-Share, an SOA (service-oriented architecture) project
that ties together financial and clinical data from hospitals statewide to help administrators, providers, and patients.
Say a 65-year-old patient walks in complaining of chest pain. “Perhaps this patient isn’t totally forthcoming about all the
types of activity that cause the pain,” Dr. Halamka says, “some of which involve Viagra.”
A physician might prescribe nitroglycerin. Fortunately, the SOA-based system will show that the patient is using Viagra —
which, if combined with nitroglycerin, can lead to a potentially fatal loss of blood pressure. “We’ve wrapped middleware around
all the major pharmacy benefit managers serving the Northeast so we can execute a secure, just-in-time query,” Dr. Halamka
explains. And even if the physician fails to spot the potential conflict between the drugs, the MA-Share system will warn
him when he tries to write a nitroglycerin prescription using the standard, Web-based online order-entry form that is another
element of the SOA-based solution.
Dr. Halamka will be describing the MA-Share system, including its achievements and its growing pains, at InfoWorld’s SOA Executive
Forum in New York on May 17 — to register, visit soaexecutiveforum.com. That’s just one of the many informative case studies covered at the meeting — and its West Coast companion to be held in
San Jose, Calif., on May 5. We hope you will join us.
