Epidemiology, Characteristics, and Treatment Outcomes of Mycoplasma pneumoniae Pneumonia in Hospitalized Adults: A 5-Year Retrospective Cohort Study
To describe the incidence rate, patient characteristics, treatments, and outcomes of adults hospitalized with Mycoplasma pneumoniae pneumonia, highlighting the significance of these findings for clinical practice.
Key Findings:
Incidence rate of M pneumoniae pneumonia was 8.5 cases per 100,000 person-years, peaking at 14.1 in 2016.
Common symptoms included cough (95%) and fever (92%); 71% were hypoxemic at admission.
In-hospital mortality was 0.4%, with 6% requiring ICU admission.
Median length of stay was longer for patients treated with macrolides and fluoroquinolones compared to tetracyclines.
Tetracycline treatment was associated with better outcomes.
The median age of patients was 42 years, with 55% male.
Interpretation:
Timely and accurate treatment of M pneumoniae pneumonia is crucial, with tetracyclines potentially being the most effective first-line treatment option due to their association with better outcomes.
Limitations:
Retrospective design may introduce selection bias.
Data limited to a single geographic region, which may affect generalizability.
Potential biases in data collection due to manual record review.
Conclusion:
The study underscores the importance of effective antibiotic treatment for M pneumoniae pneumonia, with tetracyclines showing promising outcomes, emphasizing the need for further research in diverse populations.
