Elderly Abuse in Malaysia


The official visit by the undergraduate students and their lecturers from Tzu Chi University from Taiwan ended a week ago.
 
During that visit, I talked about elderly care and abuse, particularly within the Malaysian context because I feel this is one area which is not very much talked about, not easily detected, and in fact, what we know is probably the tip of the iceberg only. This forum would also provide a space for our students to interact with the Taiwanese students as Taiwan has a good legal provision for the elderly, although Professor Hanson Huang (extreme right in front row, pic) from this team of Tzu Chi university said that the problem still remains a concern as the issue is not the law, but the implementation of the law.

In Malaysia, elderly is defined as one who is “60 years and over”  (adapted from: United Nations World Assembly on Ageing, Vienna, 1982). Some would further divide them into the  “young old”, aged 55-75 years old, and the “old old”, aged above 75 years old.

Unfortunately, many of us as healthcare professionals have narrow perception on what health is. We often define health as an “absence of disease” as defined by Sidell (1995).

On the other hand, the World Health Organization (WHO) gives a more wholistic definition of health:

“the state of complete physical, mental and social well-being” (World Health Organization,1995)

The elderly population in Malaysia has increased from 5.9% in 1991 to 6.5% in 2000. And it is expected that the proportion of people age 60 years and above in 2020 would increase further to 9.5% (Sherina et al, 2005). The life expectancy of Malaysian men and women in 1957 was 55.8 years and 58.2 years respectively, but today, it is 71 for men and 74 for women.

Contrary to what many believe, elderly abuse is not only confined to physical abuse, but, may also be sexual, or emotional abuse or neglect

WHO defines elderly abuse as:
"a single or repeated act, or lack of appropriate action, occurring within any relationship where there is an expectation of trust which causes harm or distress to an older person" (World Report on Violence and Health, World Health Organization, 2002)
As mentioned, elderly abuse can be:
  • Physical abuse
  • Sexual abuse
  • Emotional and psychological abuse
  • Financial exploitation
  • Neglect
  • Abandonment
Many believe that elderly abuse only occurs in nursing homes. But the truth is, more often than not, the abuser is a close relative – 80% being spouses and children of the victims or a close relative.
Another common myth is that elderly abuse would not happen in rich families although in actuality, elderly affects all ethnic groups and cuts across all socio-economic and religious lines. Those at risk are most likely to be female, widowed, frail, cognitively impaired, and chronically ill.

According to the 4th Malaysian Population and Family Survey, by the National Population and Family Development Board (LPPKN) 2011, one in three Malaysian elderly (33%) aged 60 and above are abandoned and do not receive financial support from their children. Click here and here to read further.

The main problem is that unlike child abuse (where there is the Malaysia Child Act 2001 to provide a protective legal environment for children), elderly abuse per se is not an offence in Malaysia as there is no law to explicitly deal with this. The only way is to charge any perpetrator under the Penal Code or Domestic Violence Act for physical abuse.

Under the Malaysian Domestic Violence Act 1994 (Act 521), domestic violence means the commission of any of the following acts:
willfully or knowingly placing, or attempting to place, the victim in fear of physical injury;
causing physical injury to the victim by such act which is known or ought to have been known would result in physical injury; 
compelling the victim by force or threat to engage in any conduct or act, sexual or otherwise, from which the victim has a right to abstain; 
confining or detaining the victim against the victim's will; or 
causing mischief or destruction or damage to property with intent to cause or knowing that it is likely to cause distress or annoyance to the victim
by a person against—
    his or her spouse;
    his or her former spouse;
    a child;
    an incapacitated adult
    any other member of the family. 
Under the domestic violence act 1994, the main issue of course is the fact that many of the more subtle forms of abuse such as emotional abuse, neglect and financial exploitation would be difficult to be legally charged.

Questions:
From your experience is elderly abuse? Why or why not?
What steps can you contribute to combat this society ill?

The changing trend of US Emergency Department (ED) visit (More Older Age Groups to the ED) - What about in Malaysia?

A study based on the US National Hospital Ambulatory Medical Care Survey showed ED visits for patients aged 65 to 74 has increased 34% from 1993 to 2003.

The authors conclude that if these trends continue, ED visits in US for this group (65-year to 74-year-old) could nearly double from 6.4 million visits to 11.7 million visits by 2013.

Implication: As stated by Richard D. Zane in a commentary in Journal Watch, the problem with this is not just about building bigger capacity emergency departments, but also to understand complexity of cases presented among patients in this older age group.

(Abstract)


How about in Malaysia?
I am not aware of anyone who have done a similar survey in Malaysia looking at the changing trend of ED visit – but if anyone knows of any, please email me.

A search of the Jabatan Perangkaan Malaysia or Department of Statistics Malaysia shows that the life expectancy has slightly increased from 2005 – 2007, but generally it is about 71 years for male and 76 years for female – and it is going to improve in the future. And so by this reasoning, the percentage of older people visiting the ED would probably increases.


Life Expectancy at birth (number of years)
2005 2006 2007
Male 71.4 71.6 71.9
Female 76.1 76.2 76.4

Generally, when seeing an older patient, there are three principles that we have to keep in mind. It can be remembered by the mnemonic: OLD

O – odd presentations; atypical presentations are common

L – Lots of medications [polypharmacy is common]

D – deceiving/ deceivingly normal vital signs – beware that normal vital signs can be abnormal in geriatric patients

Whatever it is, managing older patients can be quite an intriguing and challenging task due to the various physiological changes listed below.

Examples of physiological changes:

The integument

Skin atrophies and decreased density of the sweat glands resulting in altered thermoregulatory, increases risk of heat-related injuries (heat exhaustion, heat stroke, etc).

On the other hand, loss of subcutaneous body fat increases risk of hypothermia.

Cardiovascular System
Reduced ability to mount and sustain an increased cardiac output in response to hemodynamic insults.

Reduced ability to accommodate filling pressure and volume changes.

This effect may be further blunted by the various drugs the patient may be taking (e.g. a beta-blocker, calcium chanel blocker)

Pulmonary function
Chronic obstruction airway diseases, restrictive lung diseases, intercostal muscle weakening and loss of elastic recoil, less sensitivity in pulmonary chemoreceptors, and changes in the peak expiratory flow rate can negatively affect the overall efficiency of ventilation.

Renal system
Loss of renal mass and functioning glomeruli results in reduced GFR, and compromised drug and toxin elimination.

GFR begins a slow and steady decline around age 40 years and a decline in renal blood flow occur in the fourth decade at a rate of about 10% per decade.

Neurological system
Poor reflex coordination precipitating a fall or trauma due to loss of neurons and nerve fibers and slower dendrite connections.

Impaired responsiveness to pain, which can result in masking a diagnosis or resulting in an underestimation of the significance of symptoms.

Musculoskeletal system
Osteoporosis resulting in impaired mobility and risk of pathological fracture.
Immune system Decreases in T- and B-cell function and thymic atrophy can increase the geriatric patient's vulnerability to infection.
