RESUMEN
AIDS: AIDS treatment is sophisticated and complex, requiring difficult decisions about when to begin treatment, how aggressively to treat the infection, and which alternative therapies to pursue. Health care professionals need to be able to calculate risks and to help patients weigh their treatment options. Ideally, clinicians should present all options and discuss why they advocate some and not others. Unconventional treatments should also receive attention, because a patient may lend more credibility to options he or she believes is being purposefully concealed. Treatment decisions can be turned into a formula by estimating the good or bad value of each possible outcome of an action, multiplying that figure by the outcome's probability, and adding up the products from all the outcomes. Even if the person does not wish to base a decision on the formula, they have at least given careful consideration to all the issues. Creating a record of the decision-making process can also help ease regret caused by hindsight or outcome bias.^ieng
