AHRQ Stats: Trauma During Childbirth

The rate of obstetric trauma during childbirth involving instruments such as forceps or vacuums declined from 2000 to 2015, from 196 to 119 instances per 1,000 deliveries, respectively. (Source: AHRQ, 2017 National Healthcare Quality and Disparities Report Chartbook on Patient Safety.)

Study Highlights Effective Use of Blood Cultures and Diagnostic Stewardship in Pediatric Intensive Care Units

Three pediatric intensive care units (ICUs) that implemented a five-part Blood Culture Improvement Framework reduced unnecessary blood cultures by 32 percent in critically ill children, according to new research supported by AHRQ. Clinicians use blood cultures to test for the diagnosis of sepsis or bloodstream infections. However, false positive results are not uncommon with blood cultures and may lead to misdiagnosis and the unneeded use of antibiotics, contributing to the spread of antibiotic resistance. This research confirmed that diagnostic stewardship programs can be adapted and implemented by different institutions and in various clinical settings—in this case, a medical/surgical pediatric ICU, a cardiovascular ICU, and a mixed medical/cardiac ICU. The project also demonstrated that diagnostic stewardship is possible on a large scale in critically ill children. Access the abstract of the study, published in Pediatric Quality and Safety

ADHD Medication Use in Children and Adults Increased Worldwide

A new AHRQ-funded study showed a sharp increase in the use of attention-deficit/hyperactivity disorder (ADHD) medications in children and adults at 15 participating sites in North America, Asia, Australia, northern Europe and western Europe between 2001 and 2015. In all areas, methylphenidate was the most commonly prescribed drug for ADHD. Researchers found that the prevalence of ADHD medication use among children increased over time in all countries and regions, and the absolute increase per year ranged from 0.02 percent to 0.26 percent. Among adults aged 19 years or older, the prevalence of any ADHD medication use in 2010 varied between 0.003 percent and 1.48 percent.

AHRQ Researchers Propose a Care and Learn Model To Inform Research To Improve Care Delivery and Outcomes

A group of AHRQ researchers has designed a model to analyze the agency’s research portfolio, identify gaps, develop and prioritize its research agenda and evaluate its performance. The model connects two broad functions of the health care system: caring and learning, emphasizing that the health care system’s primary function is to respond (and improve that response by learning) to the needs of people by caring with evidence. The agency and the health services research and improvement communities can use this care and learn model to frame an evidence-based understanding of vexing clinical, health care delivery and population health problems and to identify targets for investment, innovation and investigation. Access the abstract of the model, which was published in the Journal of General Internal Medicine
