"Improving Care for Depression in Obsetrics and Gynecology: a Randomized Controlled Trial" Article Analysis
In the article “Improving care for depression in obstetrics and gynecology: a randomized controlled trial” Melville et al. (2014) investigate the differences between the evidence-based collaborative depression care intervention and the usual care. In order to measure the central tendency of collaborative depression care outcomes was used the method of randomized two-site controlled trial. In the investigation were involved screen-positive women, who were 39 years old on average. 6875 patients who agreed to screening, 94% of them (6462) completed screening, 16% (1019) were screened positive for major depression and 64% (650) agreed to take part in further eligibility screening. 44% of the participants were non-white, 99% experienced major depression, 33% suffered from dysthymia and 56% of them had posttraumatic stress disorder.
The standard deviation (SD) is the amount of data values variation. While the low SD means that data points are close to the mean, high standard deviation indicates that data points are influencing the wider range of values. In other words, the SD indicator shows, to which extent the values are dispersed or spread out. As a result of the research it was found out that the reduction of depression symptom was similar for both groups, but in 12 months and 18 months perspective the usual care group demonstrated the less depression score than the intervention group. Most of the participants in the Intervention group (96%) had one or more visit to depression care manager. The mean for intervention patients who had in-person visits was 9.6 (SD=7.1), and for those who had telephone visits 6.4 (SD=6.0). As the SD is big enough, so it may be supposed that sample is not normally distributed. So it may be concluded that collaborative stepped care model is more effective than usual care.
