Life expectancy from birth is increasing dramatically. Due to this increase, the population of elderly people will increase. Consequently, geriatric related illnesses will increase leading to increased necessity to build up comprehensive and coordinated cost effective health care services appropriate for elderly people. Frailty is not a disease, but rather considered as a syndrome requiring comprehensive and multidisciplinary care approach. It is a prevalent reversible pathological transitional stage between healthy aging and disability. Frailty is associated significantly with increased health care utilization, mortality, and comorbidities such falls, hospitalizations, physical dependence, and poor perception of health. The aim of this review is to compile existing literature on the economic cost of frailty syndrome among elderly people in the recent years. Search queries were constructed to look for articles related to the economic cost of frailty in the electronic databases available at the National University of Malaysia library for articles published between the years 2011 and 2019. The accessed electronic database included New England journal of medicine, Science Direct, SCOPUS, BMJ, Cochrane, and Wiley Online Library. Articles included in this review when they were original research, participants were defined as frail elderly, manuscripts written in English language, and involved clearly described measures of frailty cost. Among the literature, twenty one articles were found to satisfy the inclusion criteria of the review process. The cost of care for frail elderly was ranging from US $ 8,620 to 29,910 per patient per year. The cost of health care was ranging from US $ 2,540 to 221,400. The health care cost was accounting for 40% to 76% of the total care cost. Hospitalization cost was the highest, it was ranging from US $ 806 to 152,726. Outpatient cost was ranging from US $ 200 to 18,000. Medications cost was ranging from US $ 7 to 3,434 per frail elderly patient per year. Home help cost was ranging from US $ 804 to 19,728 per frail elderly patient per year. In conclusion, frailty is a costly syndrome. It can be considered as a cost effective target for health promoting interventions to contain future elderly cost.

Physical Activity Scale for the Elderly (PASE) is a simple, valid and reliable questionnaire that can be administered to quantify older adults’ physical activity levels during daily living. However, PASE in Malay language for use among older population is not available. The objective of our current study was to evaluate the reliability and validity of the Malay translated Physical Activity Scale for Elderly (PASE-M) for the use among older adults. Objective results of physical activity were obtained by wearing continuously an accelerometer for one week among a population of older adults in Malaysia who speak Malay language. Participants completed PASE-M twice, on day-8 (PASE-M1) and day-15 (PASE-M2). Concurrent validity between PASE-M1 and accelerometer results was assessed using Spearman’s rank correlation coefficient. Test-retest reliability for one week interval of PASE-M was tested using Spearman’s rank correlation coefficient and Intra-class correlation coefficients (ICC). Forty-four community-dwelling older adults (12 men and 32 women; mean age ± SD= 66.95 ± 5.34) participated in this study. However, only 33 participants (8 men and 25 women; mean age ± SD= 66.64 ± 5.51) were able to achieve the minimum accelerometer wearing time and filled up the PASE-M questionnaire for two times with one weeks interval. The results showed the PASE-M score was significantly correlated with vector magnitude (VM) counts (r=0.54, p<0.01), time in moderate-to-vigorous physical activity (MVPA) (r =0.55, p<0.01), energy expenditure (r =0.53, p<0.01) and walking steps (r=0.39, p<0.05). A high reliability (ICC = 0.96) was demonstrated between first and the subsequent administration of PASE-M (p<0.01, 95% CI: 0.92-0.98). The PASE-M is a valid and reliable questionnaire to assess physical activity level for Malaysian community-dwelling older adults.
