Study: Population disease management program 'the right investment'

By Molly Merrill

A population management program that matches heart disease patients to personal nurses and clinical pharmacy specialists saves lives, reduces hospital visits and drives down costs, according to a new study from Kaiser Permanente Colorado.

The study examined healthcare expenditures in two populations of patients with heart disease: A group of 628 people enrolled in the Kaiser Permanente Collaborative Cardiac Care Service, a population disease management program, and 628 matched patients receiving standard care. The goal of the study was to determine if an intensive disease management program could provide more value than usual care.

The study found that patients cared for by the CCCS experienced superior health outcomes. As compared to patients receiving usual care, CCCS enrollees had better cholesterol control, were more likely to be screened and adhere to important medications like statins and had far fewer hospitalizations.

Overall, the study found, CCCS patients had an 89 percent reduction in overall mortality and 88 percent reduction in cardiac mortality compared with patients receiving standard care.

When the researchers compared costs, they found that healthcare expenditures for CCCS enrollees were, on average, $60 less each day, for an annual average of $21,900 per patient per year.

These are exciting findings, said the study's lead author, Tom Delate, PhD, of Kaiser Permanente Colorado. 

"The goal of the CCCS is to get patients with heart disease on the right medications and deliver needed screenings and care, so one might expect to see healthcare costs go up with the increased service," he said.  "However, we found the opposite effect: the CCCS was able to keep patients so healthy that they were more likely to stay out of the hospital.  At the end of the day, expenditures from this major cost driver were reduced."

The researchers calculated total healthcare expenditures by reviewing healthcare use claims and electronic health records. They also attributed an overhead cost to the staff and systems used to administer the population management program. The analysis found that enrollees in the CCCS had lower healthcare expenditures across the board, including the following key areas:

  • Medications: $4 per day, compared to $5 per day
  • Doctor's office visits: $7 per day, compared to $8 per day
  • Hospitalizations: $19 per day, compared to $69 per day

"This program works because it is a team approach," said John Merenich, MD, study co-author and medical director of the Clinical Pharmacy Cardiac Risk Service. "Our teams of nurses and clinical pharmacists, as well as our health information technology, require significant investment. We always knew it was the right investment because it saved lives. Now we know it's also the right investment because it provides the highest quality care at a lower cost. This is the value people have been looking for in healthcare."

The study findings are published in the November issue of the journal Pharmacotherapy.
