Antibiotic point prevalence survey and antimicrobial resistance in hospitalized patients across Peruvian reference hospitals.
Article in Journal of infection and public health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundPeru reports higher levels than other countries in Latin America of resistance to antimicrobials among Gram-positive and Gram-negative bacteria, however data on antibiotic use in Peru are scarce. This study aims to estimate the prevalence and quality of antibiotic prescription in hospitalized patients and to determine the antibiotic susceptibility rates of bacteria causing key bacterial infections.
methodsWe carried out a point prevalence survey of antibiotic prescription at ten public hospitals in nine regions of Peru. Data was collected from patients hospitalized during a 3-week period, with details about antibiotic use, patient information, and antimicrobial susceptibility.
results1620 patient charts were reviewed; in 924 cases antibiotics were prescribed (57.0 %, range 45.9-78.9 %). Most of the antibiotics (74.2 %) were prescribed as empirical treatment, only 4.4 % as targeted treatment. For 9.5 % of cases the reason for antibiotic use was unknown. Cephalosporins were the most prescribed (30.0 %), followed by carbapenems (11.3 %). Ninety-four blood cultures were positive for bacterial growth, 48.8 % of the Staphylococcus aureus were methicillin-resistant, among Escherichia coli and Klebsiella pneumoniae, 51.7 % and 72.7 % were resistant to third-generation cephalosporins (3GC), 3.4 % and 18.2 % were resistant to carbapenems, respectively. Among bacteria isolated from urine cultures (n = 639), 43.9 % of E. coli and 49.2 % of K. pneumoniae were resistant to 3GC, and 0.9 % of E. coli and 3.2 % of K. pneumoniae were resistant to meropenem.
conclusionsThe overall proportion of hospitalized patients receiving antibiotics in hospitals from different regions in Peru was high, with only a small proportion receiving targeted treatment. Cephalosporins and carbapenems were the most frequently prescribed antibiotics, reflecting high resistance rates against 3GC and carbapenems in Enterobacterales isolated from blood and urine.
