Long-Term Care Services Use• Governmental investments on formal Long-term Care Services (LTCS)
– Provide higher subsidy in 2012
– Invest S$ 500 million on eldercare facilities from 2013-16
– Add 3000+ NH beds by 20161
– Planned to increase NH beds by 70% by 2020 – from 9,000 today to 15,600 1
• LTCS utilization is low compared to Western societies2
– AIC: take-up rate for some community services is less than 50%
• Should we promote take-up LTCS given that:– Limited information and awareness of the services
– LTCS can be cost-effective for the society3

• What are the factors associated with the take-up of formal LTCS? And whether they differ across different LTCS?
• Are there some sub-groups of population with extremely low utilization rates (outliners)?
• What are the potential ways to improve take-up of LTCS? Can we increase the take-up rate by impacting the caregiver’s perception on services?

Previous Studies
The Andersen Model of Health Care Utilization1
• Does not consider caregiver (CG) characteristics, which are important in the Asian context.– Care recipients (CR) for LTCS have higher dependent level – CG and CR are more likely to live together– Social norm
• Does not account for their awareness and perception about the services2
• With limited empirical studies in Asia: Hong Kong (2009), Japan (2011)3

AIC LTC Referral Study: Survey and Data
• A Longitudinal study – Dyads of care recipients and their caregivers– Three waves over a 12 month period
• Gathered information on both CR and CG: demographic, health status, financial resources, living arrangement, knowledge and awareness, etc.
• Two measures of LTCS utilization: 1) whether took-up the referral2) current LTC services use (a choice of nursing home, center-based services,
home-based services, family and friends, maid).
• CG’s perception/rating of formal and informal LTCS: quality, convenience, social connectedness, and affordability (score range from 1-5).

• Stratified sampling by:1) Service types - Day Rehabilitation, Dementia Day Care, Home Medical,
Home Nursing, Home Therapy, and Nursing Home2) Socio-economic characteristics – Seven Mosaic Singapore groups*
• Response rate : 43%
• First wave analytic sample: 1586 dyads 553 care recipients, 1027 proxies and 1502 caregivers
Note: Mosaic Singapore is a geo-demographic consumer segmentation system, developed based on more than 20 years of segmentation development expertise. It classifies all Singapore households and neighborhoods into 7 groupings that share similar demographic and socio-economic characteristics. It paints a rich picture of Singapore consumers in terms of their socio-demographics, lifestyles, culture and behaviors.

• Dependent variables: 1) whether took-up the referral2) current LTC services use (a choice of nursing home, center-based services,
home-based services, family and friends, maid).
• Independent variables: CG’s perception score on quality, convenience, social connectedness, and affordability (score range from 1-5).
• Covariates: CR’s age, sex, housing, education, comorbidity, ADL, iADL, income, Medisave status, and CG’s age, sex, housing, health, # of family members in the household, decision, and whether or not they have a maid.
• Statistical methods: 1) Logistic Regression 2) Conditional Logistic Regression

In these conditional logistic models, each patient becomes 5 observations, each stands for one type of current LTC services: community-based, home-based, nursing home, family and friends, and maid. In model 1 we only adjusted for whether referred service type; in model 2, we, in addition, adjusted for care recipients’ ADL and iADL. *p<.05 **p<0.01 ***p<0.001

Next Steps• Examine effect of use/non-use on subsequent health status, other service
use and quality of life
• System modeling the demand of formal LTCS for lower income, moderate to high ADL population
• Design a randomized controlled trial (RCT) to improve the uptake of and adherence to outpatient rehabilitation service among stroke patients
