The Pros and Cons of Observational Research

Naturalistic- Useful for obtaining research in situations where intervention would be unethical or where co-operation from participants would be unlikely. Follow infection control guidelines as per unit protocol. Assesses possible causes of inadequate dialysis. The results obtained through any other scientific methods need to be in conformity with the outcomes of skilled observation.

For example, love, affection, feeling and emotion of parents towards their children are not open to our senses and also cannot be quantified by observational techniques.

The observer himself, during the course of observation, may be affected by the process itself. Subsequently, he used such shunts, made of glass, as well as his canister-enclosed dialyzer, to treat patients in renal failure between andas reported to the First International Congress of Nephrology held in Evian in September Young rightly remarks that the valid observation cannot be hurried; we cannot complete our investigation in a short period through observation.

Those with smaller pore size are called "low-flux" and those with larger pore sizes are called "high-flux. We should finally note that studies can incorporate several design elements. Finally, the presence of the observer may influence the phenomenon itself.

Advantages and Disadvantages of Experimental Research

After several years usually at least 5—7patients on hemodialysis begin to develop complications from betaM accumulation, including carpal tunnel syndrome, bone cysts, and deposits of this amyloid in joints and other tissues.

Address any concerns of the patient and educate patient when recognizing the learning gap. Alwall also was arguably the inventor of the arteriovenous shunt for dialysis. It requires high cost, plenty of time and hard effort. The event may take place in the absence of the observer.

These synthetic membranes activate complement to a lesser degree than unsubstituted cellulose membranes. Most dialyzers have membrane surface areas of 0. For a detailed history of successful and unsuccessful attempts at dialysis, including pioneers such as Abel and Roundtree, Haas, and Necheles, see this review by Kjellstrand.

See also Levels of Evidence. These study designs all have similar components (as we’d expect from the PICO). Among the different methods of data gathering for research purposes, the survey method is preferred by many researchers due to its various advantages, strengths and benefits.

However, surveys also have their disadvantages and weak points that must be considered.
