2 Crossover trials With a crossover design each participant in a trial receives two or more study treatments in a specified order. For example, in a two-period crossover design, each person receives each of two treatments (A and B) either in the order AB or BA; the order is usually chosen at random. So the trial would consist of two groups the members of one having received the treatments in the order AB, and the members of the other in the order BA. Clearly such a design is only suitable for stable chronic conditions in which there is the limited objective of studying the patient’s response to relatively short periods of therapy.

Monitoring compliance is a crucial part of many clinical trials since, according to Friedman et al.

To the extent that the control group is not truly a control group and the intervention group is not being treated as intended, group differences may be diluted, leading possibly to an underestimate of the therapeutic effect and an underreporting of adverse effects. Differential compliance to two equally effective regimens can also lead to possibly erroneous conclusions about the effect of intervention.

Experienced investigators stay in close contact with the patients early after randomization to get patients involved and, later, to keep them interested when their initial enthusiasm may have worn off. On the other hand, uninterested or discourteous staff will lead to an uninterested patient population. 1.
