If one carefully reviews the term “treat to target” and the strategy of “tight control” (strict control), they both describe the same topic. Both try to get the patient to adequately control their disease by having a good therapeutic target identified. If the objective is not achieved, patient communication should lead to appropriate therapeutic adjustments at each visit until achieved. It seems more appropriate that “treat to target” is written in English, because this well could be clearer than its translation into Spanish and other languages. The author of this review assumes the error and the responsibility of the use of the Anglicized term.</p></span><span id="sec0015" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Methodological Considerations</span><p id="par0020" class="elsevierStylePara elsevierViewall">The international team that designed this strategy initially proposed a clear concept of what they wanted to investigate, but the medical literature was reviewed and studies with different designs were found. Without doubt, the best design to assess therapeutic efficacy is the controlled trial by far, or better yet the meta-analysis of randomized trials. This design compares two or more interventions, preferably analyzed in blinded fashion and with clear outcomes for patients groups. One of the major constraints in identifying strategic studies is that the traditional design assigns patients to an intervention that usually remains stable throughout the duration of the study. In some studies, the design allows rescue treatment for patients who have not achieved the desired goal. At the end of the project the number of patients achieving the goal (e.g. ACR20 response) are analyzed but no effort is made at each visit to modify the treatment regimen if this goal has not been reached. It should be understood that the “treat to target” strategy implies the use of a dynamic methodological design, where therapeutic adjustments are made in each visit if the initially proposed goal has not been achieved. A comparison group where other patients received usual clinical management must also exist. Intervention groups (strict control) and the comparison group should be similar and it is intended that the only thing that distinguishes them is the intervention to which they were assigned.</p><p id="par0025" class="elsevierStylePara elsevierViewall">There are certainly other variables to be analyzed: the duration of the disease, the intensity of interventions, the set goal, the frequency of visits, the duration of the study, the time to reach the goal and maintenance of long-term goal and clinical, functional and structural intervention consequences.</p></span><span id="sec0020" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Key Elements of the ‘Treat to Target’ Strategy</span><p id="par0030" class="elsevierStylePara elsevierViewall">The original<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> publication proposed as key elements that the management of patients with RA should have a clear goal and this be agreed upon between the patient and the rheumatologist. The goal to which both should aspire is remission, or in other cases an acceptable alternative goal is to achieve a low level of clinical activity. The degree of disease activity should be measured at each visit with composite indexes that include joint counts and the clinician must act accordingly if the goal has not been reached. The proposal presents an algorithm which emphasizes the importance of achieving the goal and suggests the frequency of visits (every month in many cases with clinical activity and every 3 months once the goal is reached). The algorithm points out the importance of achieving and maintaining the goal. This strategy is flexible because, in some of the points mentioned, it is important to take into account comorbidity that may cause the strict goal to not be achieved in some patients due to the additional risk that might be a consequence of polypharmacy and its side effects. It also emphasizes the importance of measuring functional and structural damage.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Evidence of its Usefulness in Clinical Trials</span><p id="par0035" class="elsevierStylePara elsevierViewall">We reviewed two publications with different search criteria, a strategy based on “treat to target”<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> and a meta-analysis that provided data on the usefulness of this approach.<a class="elsevierStyleCrossRef" href="#bib0030"><span class="elsevierStyleSup">6</span></a></p><span id="sec0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Studies Reviewed to Propose the Strategy ‘Treat to Target’</span><p id="par0040" class="elsevierStylePara elsevierViewall">Schoels Monika advised by two researchers conducted a systematic review of the medical literature to find the elements that could support this strategy. This search was made in Medline, Embase and Cochrane from the date of its implementation until December 2008. They also reviewed the abstract books of the American College of Rheumatology and European meetings of 2007 and 2008. The search was limited to humans, adults and English publications. Five thousand eight hundred and eighty-one titles were reviewed and 76 items were considered potentially useful. Twenty four articles or abstracts that apparently could have studied the strategy “treat to target” were subsequently analyzed and seven strategic intervention studies finally detected: in four of these patients were randomized to a group with a clear goal and a another group of patients to usual management; 2 more compared two different randomly assigned goals and one of them used a historical control.

The selection criteria were the following items: a) studies comparing a strategy of tight control versus usual care, b) patients with rheumatoid arthritis according to the 1987ACR criteria, c) that treatment include at least used DMARDs, anti-TNF or glucocorticoids, d) that the study measure clinical efficacy, and e) the primary or secondary outcome include DAS or DAS28.</p><p id="par0140" class="elsevierStylePara elsevierViewall">Its objectives were to evaluate whether strict treatment offered therapeutic advantages over usual standards of care and determine if the strict control group with a treatment protocol was better than no treatment.</p><p id="par0145" class="elsevierStylePara elsevierViewall">It is interesting to note that not all studies described in Schoels work were included in the meta-analysis because the selection criteria were different.

The different clinical and health systems should be analyzed in their environment to determine which is the best protocol. It is important to note that most of the studies reviewed reached very good results without the use of biological agents and that the most recent studies were included in their treatment algorithm. Lack of information impeded the conclusion of whether the ‘treat to target’ strategy with protocolized management will have the same results in patients with established rheumatoid arthritis and in other settings without the organization of the Dutch studies. The dissemination and acceptance of this strategy, analysis of obstacles, strategies for implementation and the scope of the same in the different health systems should be checked periodically.</p></span><span id="sec0055" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle">Ethical disclosures</span><p id="par0205" class="elsevierStylePara elsevierViewall"><span class="elsevierStyleBold">Protection of human and animal subjects</span>.
