Dementia affects 30-day hospital readmission rate for worse

Turns out, dementia affects the hospital readmission rate for worse.

A new study has suggested, dementia increases the risk of 30-day readmission to the hospital after discharge. Researchers in Japan recently published a study to learn more about the effects of dementia and being admitted to the hospital within 30 days of a previous hospital discharge.

About 25 percent of older adults admitted to hospitals have dementia and are at increased risk for serious problems like in-hospital falls and delirium - rapid change in mental function.

As a result, older adults with dementia are more likely to do poorly during hospital stays compared to older adults without dementia.

Until now, little was known about the effects of dementia on early hospital readmission. The researchers studied information from people 65-years-old and older who had been discharged from hospitals between 2014 and 2015 and then followed them for six months.

The team was looking for unplanned readmissions to the hospital within 30 days of the patient's discharge.

Older adults with dementia had about twice the risk for hospital readmissions compared to the risk for those without dementia. However, the rate of risk depended on the older adult's diagnosis.

For example, people with dementia who were hospitalized for hip fractures were at higher risk for hospital readmission than people with dementia who were diagnosed with gallbladder inflammation.

In 17 of the top 30 most common health conditions, older adults with dementia were more likely to be readmitted to the hospital than people without dementia.

The researchers noted that three issues may raise the risk of being readmitted to the hospital if you have dementia:

- Older adults with dementia may have difficulty following directions about taking medication and attending follow-up visits. This may lead to poor health and readmissions.

- People with dementia may be less able to express their symptoms, which can delay decisions to seek treatment.

- Special discharge planning for people with dementia may not be available in all hospitals.

The researchers concluded that the risk of readmission for older adults with dementia varies according to diagnosis and that special discharge planning for people with dementia is important.

The results are published in the Journal of the American Geriatrics Society.
