Risk of Respiratory Failure Evolves After Sepsis Onset

Risk of Respiratory Failure Evolves After Sepsis Onset

An analysis of 10 years of health data showed that risk factors for needing mechanical ventilation changed for patients with newly diagnosed sepsis as more time passed after onset.

In the study, 13.5% of patients with a new diagnosis of sepsis  required initiation of mechanical ventilation. Over half of these patients required mechanical ventilation within the first 24 hours after sepsis onset, while initiation occurred after 24 hours in 47.4% of patients.

Factors Associated With Initiation of Mechanical Ventilation in Patients With Sepsis: Retrospective Observational Study” examined ten years of data from the University of Michigan Medical Center electronic health data warehouse. The analysis included adult sepsis patients who did not receive mechanical ventilation at sepsis onset.

“Requiring mechanical ventilation is often a pivotal point for patients with sepsis, and their risk of respiratory failure may vary with time,” says co-author Robert Freundlich, MD, MS, MSCI, associate professor, department of anesthesiology, and chief of the anesthesiology informatics research division at Vanderbilt University Medical Center, Nashville, Tennessee. “Identifying patients at high risk and implementing targeted interventions in a timely manner has the potential to significantly improve outcomes.”

A total of 35,020 patients met sepsis criteria, and 28,747 patients were eligible for inclusion after exclusion criteria were applied. The dataset spanned July 10, 2009, to Sept. 7, 2019.

Of all eligible patients, 3,891 (13.5%) required mechanical ventilation within 30 days after sepsis onset. Of these, 2,046 (52.6%) required mechanical ventilation within 24 hours of diagnosis. Mechanical ventilation was subsequently initiated for 441 (11.3%) patients from one to two days after sepsis onset and 312 (8.0%) patients from two to three days after diagnosis. The remaining 1,092 (28.1%) experienced late respiratory failure or required mechanical ventilation three to 30 days after diagnosis.

Patients requiring mechanical ventilation had higher baseline illness severity and a higher prevalence of 27 of the 35 comorbidities on the Elixhauser Comorbidity Index, which measures the overall severity of comorbidities.

They also had a higher in-hospital mortality rate (21%) than patients who did not require mechanical ventilation (7%). Further analysis revealed that of the patients who received mechanical ventilation before but not after sepsis onset, only 35 (4% of 822) died before hospital discharge.

Factors independently associated with an increased likelihood that mechanical ventilation would be needed included race, systemic inflammatory response syndrome (SIRS) score, Sequential Organ Failure Assessment (SOFA) score, and congestive heart failure. Risks decreased with time for the SOFA score and congestive heart failure and varied for four comorbidities and three culture results.

The researchers recommend future proactive studies focusing on the effects of fluid resuscitation and other care processes on the need for mechanical ventilation in this patient population. Noninvasive ventilation and high-flow nasal cannula may also impact the need for intubation and mechanical ventilation and should be evaluated.

Alabama Nursing Graduates Begin Prestigious Vanderbilt Nurse Residency Program

Alabama Nursing Graduates Begin Prestigious Vanderbilt Nurse Residency Program

Two fall 2017 graduates of the University of Alabama in Huntsville (UAH) College of Nursing, Kate Bradley and Kristen Bertrand, have both been accepted into the Vanderbilt University Medical Center Nurse Residency Program. They will work in highly specialized health care areas, the cardiac and surgical units, respectively.

The Vanderbilt University Medical Center Nurse Residency Program is sponsored by the hospital and requires a two year commitment. Nursing graduates accepted into the program are considered full-time employees and eased into the role of professional nursing through hands-on clinical training.

Nurse residency programs are popping up across the country, helping new nurses to transition into professional practice. The nurse residency program offered at Vanderbilt University Medical Center offers a focus on delegation, time management, patient management, diversity, nursing quality and safety, research and evidence-based practice, and ethical decision making.

After completing the nurse residency program, Bradley plans to earn her Doctorate of Nursing Practice. Bertrand plans to gain clinical experience during her two-year residency, helping her to better plan her career path after working for a few years.
