WITH FOCUS ON ELDERLY POPULATION WITH MULTIPLE MEDICATIONS

OVERVIEW OF READMISSIONS

Tiffany A. FormbyHealthcare Design of the Future

September 29, 2011

READMISSION DEFINED

• Returning to hospital within specified time period original admission• CMS time period focus is 30 days• Normally for the same issue

2

READMISSION IMPORTANCE

•Hospital has to cover costs for readmission• Theory: their fault for patient returning?• Balance– longer stays in hopes for

rate

• Readmission rate important• Quality care metric

3

SUBGROUPS

4

Patients who:•Were hospitalized for heart failure • 6 month readmission rate as high as 50%

•Have multiple conditions• 1.17 odds with stroke, 1.17 with diabetes

•Stayed in hospital longer than 7 days• 1.52 odds

SUBGROUPS

5

Patients who:•Are taking 3 or more prescriptions

• Adherence problems increase exponentially

•Are elderly patients who fail to adhere to prescription plans• Attribute to 30% of hospital admissions

•Went to teaching hospitals• Study completed shows no significant

impact

SUBGROUPS

6

Patients who:•Received individualized care plan• Decrease in readmission rate in 7 studies

•Were confused by discharge instructions• Or not given instructions at all

SUBGROUPS

• Factors and criteria contribute to higher likelihood• Combined, even higher likelihood!• Odds ratio (following heart failure admission)• Race• Caucasian 1.0 (baseline)• African American 1.05• Other 1.17

7

FOR EXAMPLE…

Example: Non-white/ African American (1.17) & LOS >7 days (1.52)& hospitalized in last 6 months (1.67)& pre-existing diabetes (1.13)=3.35 odds! (just the last three conditions alone = 2.87

8

FOCUS

• Non-adherence• 30% elders hospitalized• 125,000 deaths per year in US

• Medicare publishes these rates• Typically 65 to qualify for Medicare

9

FOCUS

• Preventable more than other situations• Race, past hospitalization, etc

• Use technology to remember• Online, texting, audio cue reminder systems

10

CASE STUDY

• Why elders forget to take medication?

• Which reminding system is most effective?• Visual-pervasive• Audio-portable• Text-wearable

(Lundell, Kimel, et al.) study supported by National Institute on Aging grants

CASE STUDY RESULTS

• 10 participants• With reminding systems, adherence increase

from typical 50-80% to 96%• Common reasons for other 4%• Away from home without medication• Had company over• Overslept• Slept in• Busy: on the phone, in the yard

12

SECOND CASE STUDY

• 11 participants (mean age 83)• Use technology to improve non-adherence• Techniques similar to Aware Home• Sensors to track movement• Motion sensors in each room• On refrigerator• On phone line• On watch worn by subject• In bed

• Pillbox sensors to record adherence

13

SECOND CASE STUDY

• This time- Rules for Reminders• Prompt at closest location• Don’t prompt if in bed• Wait until off phone

68.1% no reminders73.5% time-based reminder92.3% context-based reminder

(Hayes, et al.) study supported by National Institutes of Health grants

14

MY SOLUTION

• Initial idea for a pill dispenser alarm clock• Similar to solutions in literature, Aware home• Elderly normally sleep in consistent bed• Issues- most pills taken twice a day

15

MY SUGGESTIONS

• Complete similar case with reminder systems• Increase number of participants• Track among age groups• Under 65 would appreciate a reminder system• Is context-based improvement worth investment in

sensors, etc

16

MY SUGGESTIONS

• Introduce whichever successful product in hospitals• Sell to hospital as part of care package to send

home with patients on multiple medications•Charge as a hospital supply on patient bill?

• Begin familiarizing patients with technology• Program timing to normal lifestyle (not hospital

time) to get in habit

17

CONCLUSIONS

• Cost of readmissions in spotlight• $$$ on the mind

• Address subgroups
