NEW ORLEANS — Thirty-day readmission following hospitalization for pneumonia is common in patients with underlying comorbidities such as chronic obstructive pulmonary disease (COPD), kidney and heart diseases, and dementia, according to research presented at the CHEST Annual Meeting 2019, held October 19 to 23 in New Orleans, Louisiana.

Researchers conducted a retrospective, observational, noninterventional chart review of adult patients to evaluate the clinical, radiological, and physiologic risk factors for pneumonia. Patients were admitted to the Brooklyn Hospital Center between June 2016 and June 2018.

Nearly 16% of the 349 hospitalizations secondary to pneumonia were readmitted within 30 days for all causes. Among all readmissions, 83.4% were due to pneumonia, 3.47% were due to other respiratory diseases, and 13.13% were due to all other causes. Compared with non-readmissions, patients who were readmitted were more likely to have comorbidities including COPD (31% vs 20%), kidney disease (40% vs 35%), heart disease (51% vs 40%), dementia (35% vs 17%), and other respiratory diseases such as bronchiectasis (44% vs 34%; P <.05 for all). Patients who were enrolled in either Medicare or Medicaid also had a significantly increased readmission risk (P <.05). Patients who were intubated, received noninvasive positive pressure ventilation, had issues with mobility, dysphagia, CURB65 scores of 1 and 2, or had healthcare-associated pneumonia risk also had increased rates of hospital readmission (P <.05).

Additionally, the researchers noted that a change in antibiotic treatment during the initial hospital admission or hospital admissions within the past year were risk factors for 30-day readmission.

“The results of our study suggest that there are specific underlying comorbidities, patient demographics, and admission details that can predict patients who are at an increased risk of 30-day all-cause readmission due to pneumonia,” the researchers concluded. “Early identification of high-risk patients can [include] more vigilant monitoring of pneumonia resolution, increased conscientiousness of patient education and discharge follow-up to potentially reduce readmissions.”
