What does DONALD HAGLER research?

Dr. Hagler's research explores how language barriers can impact medical treatment times for conditions such as acute appendicitis, highlighting the challenges faced by patients with limited English proficiency. He also investigates the brain development of toddlers with autism to identify early signs that predict language outcomes, aiming to enhance early intervention strategies. Additionally, he studies nursing education, developing better assessment methods to ensure that nursing students can effectively recognize patient cues in simulated environments, ultimately seeking to improve patient care standards. His work extends to understanding the effects of trauma on long-term mental health, revealing insights into how posttraumatic stress symptoms relate to changes in brain structure.

Key findings

  • In a study of 1,469 patients with acute appendicitis, those with limited English proficiency waited an average of 376 minutes for surgical evaluations compared to 348 minutes for English speakers.
  • Among 166 toddlers with autism, researchers found that structural brain differences correlated with the severity of symptoms and predicted language development outcomes.
  • In a review of 228 studies on nursing students, only 17 provided solid data on recognizing crucial health cues, highlighting a significant gap in training.
  • Out of 11,700 healthy children, 21.1% had incidental findings in brain MRIs, which informs doctors on managing unexpected results.
  • In a study of 128 patients with atrial septal defects, Doppler echocardiography showed a correlation coefficient of 0.57 with the Fick method for assessing right ventricular cardiac output.

Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract

Layrisse Landaeta V, Dincheva GR, Patel BM, Sarad N, Verzani Z +5 more

Plain English
This study looked at how language barriers affect treatment times for adults with acute appendicitis. Researchers found that nearly half of the 1,469 patients studied had limited English proficiency, and these patients waited longer for surgical evaluations—an average of 376 minutes compared to 348 minutes for English speakers. However, their overall treatment outcomes, such as hospital stay and infection rates, were similar to those who spoke English well. Who this helps: This research helps patients with limited English proficiency and healthcare providers working in diverse communities.

Nurse educator

Poledna M, Gómez-Morales A, Hagler D

Plain English
This study looked at how well nursing students recognize important cues about patient health during simulation training. Out of 228 studies reviewed from the last decade, only 17 provided solid data, showing that students often overlook key signs, like abnormal breathing rates or physical changes indicating a patient's decline. Improving students' abilities to notice these cues is crucial since it directly impacts patient care and safety. Who this helps: This benefits nursing students and ultimately improves care for their future patients.

Health care provider use of motivational interviewing to address vaccine hesitancy in college students.

2021

Journal of the American Association of Nurse Practitioners

Wermers R, Ostroski T, Hagler D

Plain English
This study looked at how health care providers can use a method called motivational interviewing to encourage college students to get vaccinated. The researchers found that while flu vaccination rates improved among students, the rates for the HPV vaccine stayed the same and the meningitis B vaccine rates actually went down, despite health providers becoming better educated on how to use motivational interviewing techniques. This matters because better vaccination rates can help prevent diseases that negatively impact students' health and academic performance. Who this helps: This benefits college students who may hesitate to get vaccinated.

Brain imaging and behavior

Franz CE, Hatton SN, Hauger RL, Kredlow MA, Dale AM +15 more

Plain English
This study looked at how symptoms of posttraumatic stress (PTS) can last for about 24 years and their link to changes in certain brain areas. Researchers found that as PTS symptoms increased in 247 men, the volumes of important brain regions, like the hippocampus and amygdala, became smaller; for example, participants with higher symptoms had a 24% lower hippocampal volume on average. This matters because it shows that even mild PTS symptoms long after trauma can lead to significant brain changes that affect stress management and overall mental health. Who this helps: This benefits patients with a history of trauma and healthcare providers treating them.

Forbes TJ, Kim DW, Du W, Turner DR, Holzer R +21 more

Plain English
This study looked at three treatments for a heart condition called coarctation of the aorta in children: surgery, stent placement, and balloon angioplasty. The researchers found that stents were generally more effective than balloon angioplasty in lowering blood pressure differences between the upper and lower body and resulted in shorter hospital stays (2.4 days for stent patients vs. 6.4 days for surgery patients). Overall, stent and surgery provided better outcomes than balloon angioplasty, especially in the short and medium term. Who this helps: This helps doctors and families of children with coarctation of the aorta by providing clearer treatment options.
