British
Council Promotes
Rational Use of Drugs
On January 21st, the British Council launched a $20,000 project to help
ensure that the erroneous prescription of drugs as well as the overuse
and misuse of medicine does not make the cure worse than the disease.
The Yemeni Society for the Rational Use of Drugs will hold two, two
week courses at Sana'a and Aden Universities for internship medical students,
financed by the council's small grants scheme.
'These students are mature enough to understand our message and flexible
enough to change their style of prescription', project manager Dr Afrah
Abdulaziz Al Zoba told The Yemen Times. 'Choosing experienced doctors for
the course presents two problems: it is difficult to find them and they
tend to be set in their ways'.
There are five main reasons for the widespread misuse of prescription
drugs in Yemen:
(1) High illiteracy rates make it impossible for people to read
the instructions, which come with the medicines. This means there is no
awareness about expiry dates.
(2) Many drug companies offer financial incentives to doctors
and pharmacists to promote certain drugs. Ethical standards can be compromised
because doctors are poorly paid and those working in government hospitals
have to supplement their meager incomes by opening private clinics at night
time.
(3) Prescription happy teachers and professors in medical colleges
pass on their habits to students who receive a lot of information about
drugs but little training in rational prescription. There are many gaps
in the doctors' knowledge as they often do not keep up to date with the
latest information and developments about new medications.
(4) Scant implementation of the law dealing with the prescription
of drugs.
(5) Self medication: people often buy drugs directly from the
pharmacy without consulting the doctor.
'We are focusing on three main areas: knowledge, ethics and economics',
Dr Al Zoba explained. 'After the first project for medical students we
hope to implement another project for the older generation of doctors'.
The Yemeni Society for the Rational Use of Drugs launched an education
programme for consumers and health workers aimed at ensuring that suitably
priced drugs reach the needy members of the society.
'We tried to establish a community pharmacy, with the focus on education,
at Sana'a University. The Dutch agreed to fund it and the university was
supportive of the idea, but the Ministry of Health did not agree', Dr Al
Zoba said.
In 1998, the society launched a Yemeni Drug Action Programme through
a TV and radio campaign, posters and discussions in mosques, markets and
gatherings of men and women, to promote the rational use of drugs.
The society pointed out that drugs are not a universal panacea. If
someone is suffering from malnutrition they need to improve their diet
and not fill themselves up with vitamins. An attempt was also made to dispel
the myth that antibiotics can cure every illness.
'I worked as a pharmacist and I have seen the problems first hand',
Dr Al Zoba emphasized. 'People come to the pharmacy and ask for half the
dose because they can't afford what has been prescribed. Or they ask for
the cheapest drugs'.
An information sheet concerning the UNDP's (United Nations Development
Programme) GEF (Global Environmental Facility) activities on Socotra provides
a penetrating flash of insight into the problems of the misuse of prescribed
drugs.
In contrast to the practice of most government hospitals on mainland
Yemen where some financial contribution is required from patients, medical
services and drugs delivered by the hospital on Socotra are free of charge.
This encourages misuse of medical services and drugs and leaves the medical
system without any local budget.
When the drugs arrive, unnecessary and uncontrolled prescription and
distribution habits usually deplete stocks in less than two weeks as the
local population tries to get as many drugs as possible. Some people will
even pretend to be sick to get drugs which will be stored and self prescribed
according to the limited knowledge of the individual.
In rural areas foreigners are always asked for drugs and when drugs
are available, people bring many of their children in order to get as much
medicine as possible making rational prescription impossible. Injections
are generally preferred to drugs taken orally even though they are cheaper
and more effective. Infusions of dextrose and saline are often self administered
even for minor illnesses. In popular thinking blood transfusions cure everything
and they are certainly overused and would be done even more frequently
if it were cheaper and more easily accessible.
There are 28 pharmacies on Socotra. They differ considerably in the
number of drugs available and in the medical know-how of the owners who
often prescribe drugs themselves.
Dr Al Zoba, no stranger to the intractable problems of Yemen's health
services, admits that the society is battling against seemingly insurmountable
odds. But it is better to light one candle than curse darkness.
'We are an NGO. We can't make laws, we can't improve the health services
but we can exert some pressure and make some suggestions. Eighty doctors
will be trained to prescribe drugs rationally. Imagine how many patients
they will treat throughout their working lives'.

Your Eyes and Computers (VDUs)

There is disagreement about whether computer screens (VDUs) can cause damage
to your eyes but we do know that environmental factors affect visual comfort
and performance. This article is intended to help you to have a more pleasant
and less fatiguing work environment.
Computer (VDU) users complain about their eyes about twice as often
as other people at work. If you are about to start work with a VDU, you
should have an eye examination. The optician can then see if there are
any problems which could give you trouble and advise you how to avoid them.
Eyestrain:
Even though you can see clearly, it is still possible to have tired
eyes. If your eyes are having to take in a large amount of detail over
a long period of time, eyestrain is more likely.
Eyestrain is the term used to describe a wide range of problems including
tiredness, irritation, soreness and sensitivity to light.
Computer (VDU) users are more prone to eyestrain than the average worker.
The most common causes are: -
1.A fault in the focusing of the eye;
2.The eyes not working "as a team";
3.Incorrect positioning of documents;
4.Unsuitable lighting;
5.Poorly designed work areas;
6.Lack of adequate maintenance and poor placing of the VDU and
keyboard.
All of which can be corrected by attention to the work environment and
regular visits to an eye doctor.
CONTACT LENSES
Contact lenses are suitable for use with VDUs as they give less distortion
and reflection than glasses. However, when first used with VDUs, problems
may arise if the lenses start to dry. This problem usually disappears once
the wearer has got used to the lenses. It is also important to blink normally
and to keep contact lenses clean and free from scratches to achieve the
best possible vision in all circumstances.
Older VDU users who have contact lenses for an existing eye problem
may need additional reading glasses.
EYE CO-ORDINATION
Each eye is moved by six muscles; but if these, or the nerves controlling
them, do not work properly, it makes it difficult for both eyes to work
together. This may make your eyes tired and sore, and you may get headaches
or blurred or double vision. It is a simple matter for your optician to
find this during an eye examination.
EYE EXERCISES
After an eye examination, if your optician finds that your eyes do
not work together properly, eye exercises can sometimes solve the problem.
During treatment, you may have to spend a short time each day on the exercises.
It might also be necessary to wear glasses.
MEDICAL HISTORY
If you have headaches, or marked discomfort from "flicker",
or problems with VDUs, televisions or fluorescent lighting, you should
be sure to mention this when you have your eyes examined.
WHICH SCREEN?
VDUs with "non-reflective" screens and clearer letters have
improved working conditions for users. Unfortunately, models with highly
reflective screens and poor letter definition are still marketed. You should
not be able to see reflections when sitting infront of an unlit screen.
VDUs come in a variety of screen and character colors and increasingly,
with multicolor displays. The legibility and suitability of the display
are affected by the contrast between the screen and the characters as well
as the general office lighting. It is not primarily a question of the colour.
Brightness and contrast controls should be handy. Most VDU screens can
be adjusted to suit your requirements.
Regular maintenance of VDUs is essential. The screen should be kept
clean and any flicker or unwanted movement of the letters should be corrected
as soon as possible.
POSITIONING OF EQUIPMENT
Incorrect siting of equipment may cause strain. Frequently, a VDU is
positioned where a typewriter was originally, but good positioning for
typing is often very poor for VDU work.
Keyboards need to be movable and should be positioned to ensure maximum
comfort for the user. The position of documents should also be variable.
The overall work range is normally between 33 Ð 100 cm. There should
be sufficient space behind your VDU for you to be able to look past the
screen so that your eyes can relax.
PSYCHOLOGICAL CONSIDERATIONS
Some tasks are tiring, because they are physically or mentally demanding
or monotonous. Complains of eyestrain can be caused by psychological facts
such as stress, repetition and lack of interest. Users should have a different
task for short periods every hour or so to help reduce tiredness.
During training, mental concentration and unfamiliar visual tasks can
be expected to cause eyestrain. Usually this doesn't last long. If it does,
have your eyes examined!
Routine eye exam by an eye specialist is very important. It is your
sight and your eyes need all the care they can get.
