A new UCLA public health report has revealed that diabetes patients with abnormal blood sugar levels spend longer periods in hospital and have costlier visits.

The report released by Scripps Health, a nonprofit health care system based in San Diego, also revealed that one out of every three patients admitted to the hospital in California suffered of diabetes.

Athena Philis-Tsimikas, an endocrinologist, corporate vice president of the Scripps Whittier Diabetes Institute said, "Data from the new studies suggest poorly controlled blood sugar readings could serve as a marker for better managing the care of patients with diabetes both during their hospital stays and after they have been discharged".

He mentioned that their research supported having more caregivers in the hospital and clinic settings. The caregivers should focus to identify these patients and work to ensure that their diabetes is properly managed.

For the study, the researchers looked at 9,995 patients with diabetes who were admitted to all Scripps Health hospitals in San Diego county between 2012 and 2013. These patients received blood sugar modeling during their stays.

The findings revealed that stays of patients with poor glucose control averaged 8.5 days longer than those with normal patients. These patients also had average hospitalization costs of $16,382, compared to $13,896 for patients with controlled glucose levels.

In the second study researchers analyzed blood sugar data among 2,024 patients with diabetes who were admitted to Scripps Memorial Hospital Encinitas between 2009 and 2011.

The reveals also revealed that patients who had high glucose readings had significantly longer stays and sustained higher total costs than those with low glucose readings.

The results might help encourage a change in healthcare payment models that focus on reducing cost and improving patient outcomes.
