what is the best test to monitor the effectiveness of the treatment?

The randomized controlled trial(RCT) is the most reliable methodology for assessing the efficacy of treatments in medicine. In such a trial a defined group of study patients is assigned to either receive the treatment or not, or to receive different doses of the treatment, through a formal process of randomization.

How to evaluate the effectiveness of a treatment?

Once the committee identified the health conditions upon which to focus (see Chapter 2), it had to determine how to evaluate the effectiveness of treatments for those conditions. There are a number of ways to show that a given treatment is effective in treating a disease or clinical condition. Studies of treatments typically start either with laboratory studies establishing a possible or plausible effect of a treatment or with uncontrolled clinical observations of that effect. Small pilot studies, larger controlled trials, and, finally, studies of efficacy in large clinical populations gradually build a case for the value of a given treatment. There is no point along this sequence when a treatment is unequivocally “proven” efficacious, since no single study is totally free of all methodological flaws and even a set of studies may be flawed and produce misleading conclusions. The strength of evidence for or against a given treatment can be graded, however, and there is a point at which the medical and scientific communities can reach consensus about the efficacy (or lack thereof) of a treatment (Guyatt et al. 2000). In this chapter, we will review these “rules of evidence” and indicate how they can be applied to treatments for Gulf War veterans' health problems.

What is the weakest evidence for treatment effectiveness?

Still weaker evidence for treatment effectiveness comes from uncontrolled clinical observationsor anecdotes. These types of studies may involve small numbers of patients, treatments that are not well defined or that vary from patient to patient, variable periods of follow-up, unstated or varying rules for selecting patients for study, or outcome measures of unknown validity (e.g., patient says he “feels better”). They may not be studies at all in the sense that there is any organized effort to answer a scientific question about a treatment. They may simply be the collected reports of the experiences of patients who share some basic characteristics of illness and treatment. Although these kinds of studies can appear in major professional journals because they doprovide someevidence of potential treatment effectiveness, they are generally not considered to provide strong evidence because of the many possible competing explanations for the observed effect that they cannot rule out.

How to provide evidence of efficacy?

Other kinds of studies (i.e., quasi-experimental designs) can provide evidence of treatment efficacy, too. In situations where it is technically or ethically impossible to run concurrent control groups, a series of “off/on” periods of treatment in a single group of patients can be studied. In these studies treatment is administered to a single group of patients and then taken away. Evidence of efficacy is provided if the benefit is consistently seen when treatment is given and the benefit disappears when treatment is not given. This is a specific example of a before-afterstudy design without controls. A single round of off/on provides very weak evidence for effectiveness unless results are unusual and dramatic, because many other things occurring at the same time as the treatment may have caused the result. Being able to repeat the effect over and over again strengthens the argument for the treatment, rather than something else, being the cause of the effect.

Why is there no evidence of treatment effectiveness for most medical problems in Gulf War veterans?

If we adhere to this terminology, we will find that there is very little formal evidence of treatment effectiveness for most treatments for medical problems in Gulf War veterans because relatively few true effectiveness studies have been done on any medical condition.

What are the features of a randomized trial?

Randomized trials typically include other features that increase the strength of the conclusions about cause-and-effect relationships between the treatment and the outcome of interest. Some patients may be excluded from the study because they have conditions that make it impossible to evaluate outcomes or gather data (e.g., extremely elderly patients may be excluded from a study of a cancer treatment because too many of them would die of other conditions before the end of a five-year follow-up period). The study of the efficacy of a drug may include lab tests that measure the level of the drug in the bloodstream. This is done to ensure that the patients assigned to the treatment group actually received the drug while the patients randomized to “no treatment” did not take it on their own. A study may include near-term clinical measures of benefit (e.g., reduction in blood pressure or cholesterol level) as well as long-term objective measures of benefit (e.g., remissions of tumors, mortality) or long-term subjective measures of benefit (e.g., self-reported pain or functional status levels).

What is a case control study?

In this study design, patients are assigned to study groups based on the resultsof treatment rather than the treatment itself. One might, for example, identify some patients who survived one year after a heart attack and other patients who died within a year. If most or all of the patients who survived received a certain kind of treatment and few or none of those who died received the treatment, the treatment might have improved the odds of survival. In this kind of study and in the cohort study, there is no direct control over who receives what treatment, so there may be competing explanations for the effect. Perhaps only healthier, stronger patients received the treatment, with the possibility that the survival benefit was related to their health and strength rather than the treatment. Because this design leaves open many competing explanations, it is less powerful than an RCT for assessing treatment effectiveness and is usually followed by an RCT to confirm findings.

How to determine a policy to follow in developing guidelines about effective treatments for Gulf War illnesses?

In determining a policy to follow in developing guidelines about effective treatments for Gulf War illnesses, we suggest that both types of studies be considered in developing a hierarchy of evidence. We suggest that this be done by considering a “parallel” hierarchy with efficacy studies on one side and effectiveness studies on the other , as illustrated in Table 3-1.

Why is it important to have a patient's impressions?

Obviously if a patient feels better, that's great. So in one sense, a patient's impressions are extremely important--the goal of therapy is, after all, to restore her to mental and emotional well-being. But for the purposes of determining which treatments are most effective in which situations, there are several problems with a patient's own impressions of her progress. The first is simply that people in distress tend to get better. This is known as regression to the mean, or average, and it's when people have a tendency to move toward an average level of functioning or happiness from whatever state they are in. If you're really happy, you're most likely to get sadder, and if you're really sad, you're most likely to get happier. People spend most of their time feeling average, so moods that are above or below average are likely to return to this average. Since people usually enter treatment because they're feeling especially bad, they're likely to get better over time not because of anything the therapist is doing, but simply because they're regressing to the mean.

Why is cognitive therapy effective?

These kinds of studies have shown that for depression and panic disorders, cognitive therapy is most effective, potentially because these disorders are in part caused by the kind of negative thinking directly addressed by cognitive therapy.

Do patients expect to get better?

If patients expect to get better, they probably will , at least in some ways. On a related note, patients sometimes feel like they should be getting better as a way of justifying the effort involved in seeking treatment; going to see the therapist, paying money for sessions or for drugs.

Do people in therapy expect to get better?

Secondly, people in therapy expect to get better. You might have heard of the placebo effect. For a quick summary, imagine you have a headache: what do you usually do to fix it? Let's say you take aspirin or some other painkiller, and usually the headache goes away. You expect that when you take aspirin, your head will feel better. Now let's say your friend, playing a practical joke on you, secretly replaces your aspirin with similar-looking sugar pills. The placebo effect predicts that when you take these sugar pills for your headache, you will still feel at least a little better because you expect to; some of the effect of the painkiller is that you think you'll get better when you take one. This is especially true of therapy's effect on mental illness, since the symptoms are often much more subjective than a headache to begin with. If patients expect to get better, they probably will, at least in some ways. On a related note, patients sometimes feel like they should be getting better as a way of justifying the effort involved in seeking treatment; going to see the therapist, paying money for sessions or for drugs. It would be difficult to put in this kind of effort while thinking it was all worthless; therefore, some patients decide to believe in treatment.
