- Multidrug resistance assessment of indoor air in Portuguese long-term and acute healthcare settingsPublication . Santos-Marques, C.; Teixeira, C.; Pinheiro, R.; Brück, W. M.; Pereira, Sónia Gonçalves; dos Santos Marques, Catarina; Silva Teixeira, Camila; Pinheiro, Rafael; Gonçalves Pereira, SóniaBackground: Knowledge about air as a pool of pathogens and multidrug resistance (MDR) in healthcare units apart from hospitals is scarce. Aim: To investigate these features in a Portuguese long-term healthcare unit (LTHU) and a central hospital (CH). Methods: Air samples were collected and their microbial load (bacteria and fungi) determined. Bacterial isolates were randomly selected for further characterization, particularly identification by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry, antimicrobial susceptibility testing, and polymerase chain reaction screening of extended-spectrum b-lactamases, carbapenemase genes and mecA gene, with RAPD profile assessment of positive results of the latter. Findings: A total of 192 samples were collected (LTHU: 86; CH: 106). LTHU showed a statistically significantly higher bacterial load. CH bacteria and fungi loads in inpatient sites were statistically significantly lower than in outpatients or non-patient sites. A total of 164 bacterial isolates were identified (MALDI-TOF: 78; presumptively: 86), the majority belonging to Staphylococcus genus (LTHU: 42; CH: 57). The highest antimicrobial resistance rate was to erythromycin and vancomycin the least, in both settings. Eighteen isolates (11%) were classified as MDR (LTHU: 9; CH: 9), with 7 MDR Staphylococcus isolates (LTHU: 4; CH: 3) presenting mecA. Nine non-MDR Staphylococcus (LTHU: 5; CH: 4) also presented mecA. Conclusion: The current study highlights that healthcare unit indoor air can be an important pool of MDR pathogens and antimicrobial resistance genes. Also, LTHUs appear to have poorer air quality than hospitals, as well as supportive areas compared to curative care areas. This may suggest possible yet unknown routes of infection that need to be explored.
- Prevalence of acute and chronic wounds – with emphasis on pressure ulcers – in integrated continuing care units in Alentejo, PortugalPublication . Furtado, Kátia A. X.; Infante, Paulo; Sobral, Ana; Gaspar, Pedro; Eliseu, Graça; Lopes, ManuelThe aim of the study was to describe the prevalence and general characteristics of acute and chronic wounds in 2018 in Alentejo (Portugal) continuing care units. In order to look at associations, wound characteristics studied were location, type, place of acquisition, number, and duration, and patient characteristics were sex, age, and presence of risk factors. During the first 2 weeks of February 2018, a total of 770 patients were assessed at continuing care units of Alentejo. Of these, 135 exhibited wounds, a prevalence of 17.5%. Almost two out of three patients (63%) had arterial hypertension, slightly more than one in three (37%) had a stroke and/or immobility and 30% had diabetes. Of the total wounds identified, 18% were acute wounds and 82% were chronic wounds. Of the 24 acute wounds, traumatic wounds (76%), and surgical wounds (22%) were the most prevalent. The four types of pressure ulcers represented 80% of the chronic wounds. The median duration of the pressure ulcers was 5.5 months and 25% had duration over 10 months.
