What is the number needed to treat?
The number needed for treatment (NNT) is statistics in epidemiology referring to how many people need treatment to prevent a single bad result. People use this statistics in considering the costs and benefits of treatment and writing political recommendations. If the number required for treatment, where doctors' providers only need to heal one person to prevent the wrong result, it claims strongly in favor of the provision of treatment. If 1,000 people need treatment to prevent poor outcome, treatment may not be effective enough to include in area recommendations.
To determine the number of treatment needed, people need two sample populations with the same health condition. One population receives treatment, such as insulin therapy of diabetes, while the other is a control population and does not receive any medical interventions. People compare the rate of success between populations. In the event that no one in the control group improves and people who receive treatment, the number needed for treatment does not matter. In SIitation, where the doctor knows that treatment will be successful, the doctor knows that it will be worth related risks. If the number needed to treat is higher, the situation becomes more complex and the physician must think about the effectiveness of the treatment, risk and case of the patient.
It also has the important consequences of politics. For example, insurance providers may deny coverage based on the number of treatment needed so high that the effectiveness of treatment is questionable. They will not pay for treatment that seems to be successful only in a limited number of patients. People can be able to appeal and provide supportive evidence to show how the treatment will benefit them. Policy creators can also consider it when checking applications for new medicines and treatment; If the treatment does not seem to be very effective, it may not be approved by the application for sale in the public.
People can also consider the number of damage needed. This applies to how many people receive treatment than people fromThey do bad result due to treatment. While many medical treatments carry risks, some are more risky than others. If this number is low, treatment may not be acceptable for use, except for very limited circumstances. For example, invasive surgery with serious risks of complications should only be given in the case of the necessary, in a patient who has the ability to consent.
