Introduction

Points expanded from notes to prove and in depth knowledge of the subject. To Coursework.info reader, the comments I received pointed out my grammar errors, so please take note of this. Computers in Hospitals Hospitals have taken full advantage of what ICT can offer in the modern era. Computers can be used in Hospitals for two main purposes - ledger systems and for patient care. A basic ledger system ensures department spending is under the allocated allowance. This means that companies will not be wasting money, as the availability to spend over budget isn't there. The software used in ledger systems are controlled by a Computer system. Also, the ledger can manage payroll. The advantages of a ledger system are that all records are easily traced. This means that employees can purchase goods on behalf of the department, but cannot deny it at a later date. This is helpful for a company as they now when and who makes a purchase. Another advantage of using a basic ledger system in your business is that companies can now pay in bulk as all purchases are sent through the system. This means that if the department of neuroscience and the department of pharmacology both purchased a microscope, it would send to the ledger system. It would purchase the two microscopes together. They're buying in bulk; therefore the companies will give them a cheaper price for the product. This is known as 'economies of scale'. Budgets are set at the start of the working year. This means that all departments are clearly informed of their budget for the whole year. ...read more.

This is good because now the chance of giving a patient the wrong blood type is now decreased. Less money is now wasted on correcting mistakes, this means that money can go elsewhere in the Hospital. Money is now saved from department budgets. Also, as the blood type is properly characterised there is less chance of cross contamination, as we know exactly what blood types patients are and what would go wrong is we mixed the two. However, if somebody was to manually transcribe the blood types then there may be input errors, which may lead to false decisions being made. In the pathology lab ICT is essential for many tasks. One example of this would be to send results of the composition of blood to other wards. This would be done through a LAN (local area network) as it is a form of intranet it is protected and secure, meaning unwanted people cannot view it. Whilst over a WAN it can be hacked and intercepted easier. As the results are sent through an intranet this means results can be received quicker, meaning action can be prompt. Which saves time and money. In the Pathology lab Computers automate tests. This is good because now is will reduce human error, such as input or transposition errors. As the tests are automated this means less experts are needed to withdraw them. Now departments can spend less money on staff and purchase more goods such as medicine. However, you cannot be over dependent on the Computer system. There may be a power cut or it may have a manual malfunction. ...read more.

Conclusion

This means a reduction in data loss. However, a disadvantage of using these systems is that the system is often asking questions which require common sense. This could leave the patient feeling frustrated. This is because a human can make comfortable assumptions whilst a Computer cannot make a guess as it would be totally random. Also, another disadvantage of an expert system is that errors could occur, meaning that the department that uses the expert system is then unable to perform normally. As Expert systems use electricity, if there was a power cut then the department would again be incapable of performing normally. The future for Hospitals in comparison to technology is optimistic. One method that is in discussion for future use in Hospitals is the use of long distance surgery, it shall reach $2.4 billion this year and nearly triple to $6.1 billion by 2012. The method shall include analysing and operating on patients without the need of a surgeon near by. This method is widely appreciated by Hospitals around the world as it is cheaper as surgeons can increase the amount of operations two fold. However, some are sceptical of the method as you won't have precision if you aren't actually there and there may be a lag time. This means that images of a bleed may come a few seconds late, which means this could cost the patients life. Hospitals are looking into investing in Electronic Patient Records. The aim is to put all patients' records online so that all hospitals have access to them; if you were taken into any hospital anywhere in Britain you could access these details. This saves time as before you would have to request information manually. ?? ?? ?? ?? A/S ICT Unit 1 Alexander Dooler ...read more.
