There are a variety of study types that can generally be categorized according to these subsets:
Descriptive studies are used to accurately describe specific characteristics of a group of children or families, or to compare groups based on some variable. In these studies, information is obtained from participants without manipulating the environment in any way. Self-report surveys, individual or group interviews, behavioral observation, and clinical information reviews are all descriptive approaches. Descriptive studies answer questions such as, “What do first-time mothers-to-be think about breastfeeding?” or “Is there a relationship between school performance and BMI?” or “How do children handle bully behavior?”
Clinical trials are used to test the efficacy of an intervention such as a new illness prevention strategy, diagnostic test or clinical treatment. The results of clinical trials can lead to changes in care. Pediatric practices can play an important role. For example, the latest American Academy of Pediatrics Urinary Tract Infection Clinical Practice Guidelines were a direct outcome of clinical trials conducted in partnership with primary care practices. In the video below, the doctors from Children’s Hospital of Pittsburgh of UPMC who led this study, discuss the guidelines and other UTI clinical research activities.
Practice improvement studies are used to test changes intended to improve the way patient care is delivered and/or increase the efficiency and effectiveness of how a practice is run. For example, a clinical practice may want to test whether a change in how exam rooms are assigned can reduce waiting room time for patients, or how adding prompts to the electronic medical record improves the documentation of developmental milestones.
