Abstract Ventilator-associated pneumonia (VAP) is defined as a pulmonary infection acquired after at least 48 hours of assisted ventilation. They represent the most frequent healthcare-associated infectious complication (30-50%). The diagnostic, therapeutic and preventive quality of their management represents a major challenge for intensive care physicians, as well as an important economic issue.
The aim of our work is to determine the epidemiological, clinical, therapeutic and prognostic aspects of healthcare-associated pneumonia, as well as to study the microbiological profile of these types of infection in our department.
This is a retrospective study carried out in the P17 surgical resuscitation department of CHU Ibn Rochd in Casablanca over a 2-year period from January 1, 2023 to December 31, 2024. We collected 510 lung samples including 1 BAL, 19 ASP, 486 PBDP and 3 sputum from patients hospitalized in this department. We included in our study patients hospitalized in the P17 surgical intensive care unit, who had taken lung samples and received mechanical ventilation.
Among the 1,770 intubated and ventilated patients admitted to the intensive care unit during the period of our study, 238 patients had care-associated pneumonia, an incidence equal to 13.44%.
The mean age of the patients was 57.04 years, with extremes ranging from 16 to 67 years. There was a clear male predominance: 67% of patients were male.
In all patients, the most frequent reason for hospitalization was post-operative management.
In our study, the use of antibiotics prior to resuscitation was noted in 40 patients (16.81%). Amoxicillin-clavulanic acid was the most commonly used antibiotic.
Purulent secretions were observed in 114 patients (47.9%). A very high CRP level (over 100 mg/l) was found in 52% of our patients. 42% of these patients showed hyperleukocytosis, 12% leukopenia and 35% thrombocytopenia.
On all selected samples, 6 main bacteria were found; Acinetobacter baumannii was the most frequent representing 28% of all germs, followed by Pseudomonas aeruginosa 14%, Klebsiella pneumoniae ssp pneumoniae 13%, Staphylococcus aureus 8%, Escherichia coli 6%, then coagulase-negative Staphylococcus 5%. In our study, of the 238 positive cultures, we found 29 polymicrobial cultures versus 209 monomicrobial cultures.
In our series, 209 patients (87.8%) were treated with antibiotics. Overall, the mean duration of antibiotic treatment was approximately 12.9 days. Poly-antibiotic therapy was the usual mode of treatment, accounting for 85% of cases (179 patients). Imipenem, amikacin and colistin were the ATB combinations most commonly used in these patients.
Progress was assessed clinically (temperature, hemodynamic and respiratory status, state of consciousness, etc.), biologically (CBC, blood gas, CRP, renal function, etc.) and bacteriologically. The average length of hospital stay for patients with healthcare-associated pneumonia was 22 days, with extremes ranging from 1 to 102 days. This outcome was favorable in only 47 of our patients (19.75%), while 191 of our patients (80.25%) died.
