Sputum culture and antibiotic resistance in elderly inpatients with exacerbation of chronic obstructive pulmonary disease at a tertiary geriatric hospital in southern Vietnam.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo determine the rate of positive culture sputum and related factors as well as the microorganism features and antibiotic susceptibility of pathogens in elderly inpatients with exacerbation of chronic obstructive pulmonary disease (COPD) in Thong Nhat Hospital, Vietnam.
methodsThis cross-sectional study included elderly patients admitted to the hospital because of exacerbation of COPD. Data of their medical history, symptoms and signs were collected, and the patients were instructed to collect sputum sample. A positive culture was identified with the growth of ≥ 10
resultsThere were 167 participants (mean age: 77.5 ± 8.8 years, 87.4% male). The culture-positive rate was 25.1%. A higher proportion of positive culture was among participants with purulent sputum (p = 0.029) and with severe and very severe airflow obstruction (p = 0.005). Three most common agents were Acinetobacter baumannii (24.4%), Klebsiella pneumoniae (22.2%), and Pseudomonas aeruginosa (15.6%). Despite high resistance to almost other antibiotics (> 50% resistance), Acinetobacter baumannii and Pseudomonas aeruginosa were sensitive to colistin, tobramycin, and gentamicin (> 80% susceptibility). Klebsiella pneumoniae was highly sensitive to almost common antibiotics (> 80% susceptibility). Among Gram-positive pathogens, methicillin-resistant Staphylococcus aureus (MRSA) was completely sensitive to vancomycin, teicoplanin, and linezolid.
conclusionThe sputum culture-positive rate in this study was not high. Most prevalent isolated pathogens were Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Acinetobacter baumannii and Pseudomonas aeruginosa were sensitive to tobramycin, gentamicin, and colistin. Commonly used antibiotics remained effective against Klebsiella pneumoniae. MRSA was sensitive to vancomycin, teicoplanin, and linezolid.
