Although there are simple and low-cost measures to prevent healthcare-associated infections (HAIs), they remain a major public health problem. Quality issues and a lack of knowledge about HAI control among healthcare professionals may contribute to this scenario. In this study, our aim is to present the implementation of a project to prevent HAIs in intensive care units (ICUs) using the quality improvement (QI) collaborative model Breakthrough Series (BTS). A QI report was conducted to assess the results of a national project in Brazil between January 2018 and February 2020. A 1-year preintervention analysis was conducted to determine the incidence density baseline of the 3 main HAIs: central line-associated bloodstream infections (CLABSIs), ventilation-associated pneumonia (VAP), and catheter-associated urinary tract infections (CA-UTIs). The BTS methodology was applied during the intervention period to coach and empower healthcare professionals providing evidence-based, structured, systematic, and auditable methodologies and QI tools to improve patients’ care outcomes. A total of 116 ICUs were included in this study. The 3 HAIs showed a significant decrease of 43.5%, 52.1%, and 65.8% for CLABSI, VAP, and CA-UTI, respectively. A total of 5140 infections were prevented. Adherence to bundles inversely correlated with the HAI incidence densities: CLABSI insertion and maintenance bundle (R = −0.50, P = .010 and R = −0.85, P < .001, respectively), VAP prevention bundle (R = −0.69, P < .001), and CA-UTI insertion and maintenance bundle (R = −0.82, P < .001 and R = −0.54, P = .004, respectively). Descriptive data from the evaluation of this project show that the BTS methodology is a feasible and promising approach to preventing HAIs in critical care settings.

Healthcare-associated infections (HAIs) have a significant impact on patients' morbidity and mortality, and have a detrimental financial impact on the healthcare system. Various strategies exist to prevent HAIs, but economic evaluations are needed to determine which are most appropriate. To present the financial impact of a nationwide project on HAI prevention in intensive care units (ICUs) using a quality improvement (QI) approach. A health economic evaluation assessed the financial results of the QI initiative 'Saúde em Nossas Mãos' (SNM), implemented in Brazil between January 2018 and December 2020. Among 116 participating institutions, 13 (11.2%) fully reported the aggregate cost and stratified patients (with vs without HAIs) in the pre-intervention and post-intervention periods. Average cost (AC) was calculated for each analysed HAI: central-line-associated bloodstream infections (CLABSIs), ventilator-associated pneumonia (VAP) and catheter-associated urinary tract infections (CAUTIs). The absorption model and time-driven activity-based costing were used for cost estimations. The numbers of infections that the project could have prevented during its implementation were estimated to demonstrate the financial impact of the SNM initiative. The aggregated ACs calculated for each HAI from these 13 ICUs - US$8480 for CLABSIs, US$10,039 for VAP, and US$7464 for CAUTIs - were extrapolated to the total number of HAIs prevented by the project (1727 CLABSIs, 3797 VAP and 2150 CAUTIs). The overall savings of the SNM as of December 2020 were estimated at US$68.8 million, with an estimated return on investment (ROI) of 765%. Reporting accurate financial data on HAI prevention strategies is still challenging in Brazil. These results suggest that a national QI initiative to prevent HAIs in critical care settings is a feasible and value-based approach, reducing financial waste and yielding a significant ROI for the healthcare system.

Well-defined locations of pemphigus cases support the hypothesis of environmental factors’ involvement in its etiopathogenesis; however, these foci have never been described using specialized geographical tools. This is the first report to geo-reference pemphigus cases in a high-prevalence Brazilian region using geographic information systems. We aimed to report the spatio-temporal behavior of pemphigus foliaceus (PF) and vulgaris (PV) in southeastern Brazil, over the last five decades to describe geographical clusters, as well as to characterize the land use in the city with the highest number of cases. Patients were identified from 1965 to 2014. Maps were developed using ArcGIS software and organized into decades from 1965 to 2014. Ribeirão Preto was identified as the city with the greatest number of cases. Land use was analyzed within a 2 km-buffer surrounding the residence of each patient. A total of 426 cases of pemphigus were identified. PF was the predominant form (285 cases); notwithstanding, the number of new cases of PV rose, overtaking the number of new cases of PF in the last decade studied. Agricultural area (42%) and exposed soil (33.2%) are the most predominant land uses in Ribeirão Preto surrounding patients’ residences. This study shows high-confidence geographical foci of PF and PV, as well as provides evidence of an increase of both clinical forms over the last five decades. All cases of PV and PF are in proximity to rivers and agricultural areas which reinforce the hypothesis that environmental factors play a role in pemphigus etiopathogenesis.

Background Every year, millions of patients suffer injuries or die due to unsafe and poor-quality healthcare. A culture of safety care is crucial to prevent risks, errors and harm that may result from medical assistance. Measurement of patient safety culture (PSC) identifies strengths and weaknesses, serving as a guide to improvement interventions; nevertheless, there is a lack of studies related to PSC in Latin America. Aim To assess the PSC in South American hospitals. Methods A multicentre international cross-sectional study was performed between July and September 2021 by the Latin American Alliance of Health Institutions, composed of four hospitals from Argentina, Brazil, Chile and Colombia. The Hospital Survey on Patient Safety Culture (HSOPSC V.1.0) was used. Participation was voluntary. Subgroup analyses were performed to assess the difference between leadership positions and professional categories. Results A total of 5695 records were analysed: a 30.1% response rate (range 25%–55%). The highest percentage of positive responses was observed in items related to patient safety as the top priority (89.2%). Contrarily, the lowest percentage was observed in items regarding their mistakes/failures being recorded (23.8%). The strongest dimensions (average score ≥75%) were organisational learning, teamwork within units and management support for patient safety (82%, 79% and 78%, respectively). The dimensions ‘requiring improvement’ (average score <50%) were staffing and non-punitive responses to error (41% and 37%, respectively). All mean scores were higher in health workers with a leadership position except for the hospital handoff/transitions item. Significant differences were found by professional categories, mainly between physicians, nurses, and other professionals. Conclusion Our findings lead to a better overview of PSC in Latin America, serving as a baseline and benchmarking to facilitate the recognition of weaknesses and to guide quality improvement strategies regionally and globally. Despite South American PSC not being well-exploited, local institutions revealed a strengthened culture of safety care.

Background The Breakthrough Series model uses learning sessions (LS) to promote education, professional development and quality improvement (QI) in healthcare. Staff divergences regarding prior knowledge, previous experience, preferences and motivations make selecting which pedagogic strategies to use in LS a challenge. Aim We aimed to assess new active-learning strategies: two educational games, a card game and an escape room-type game, for training in healthcare-associated infection prevention. Methods This descriptive case study evaluated the performance of educational strategies during a Collaborative to reduce healthcare-associated infections in Brazilian intensive care units (ICUs). A post-intervention survey was voluntarily offered to all participants in LS activities. Results Seven regional 2-day LS were held between October and December 2022 (six for adult ICUs and one for paediatric/neonatal ICUs). Of 194 institutions participating in a nationwide QI initiative, 193 (99.4%) participated in these activities, totalling 850 healthcare professionals. From these, 641 participants responded to the survey (75.4%). The post-intervention survey showed that the participants responded positively to the educational activities. Conclusion The participants perceived the various pedagogical strategies positively, which shows the value of a broad and diverse educational approach, customised to local settings and including game-based activities, to enhance learning among healthcare professionals.

Objective To provide evidence of the cost savings of a quality improvement (QI) initiative preventing healthcare-associated infections (HAIs) in critical care settings. Design A micro-costing study focused on financial data related to a nationwide multicentric project preventing central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP) and catheter-associated urinary tract infection (CAUTI). Setting Brazilian public healthcare system. Participants Adult, paediatric and neonatal intensive care units (ICUs) participating in the QI initiative. Intervention This collaborative QI project implemented a multifaceted strategy to enhance infection-control measures. Participating ICUs reported the number of patients with and without HAIs and information on each HAI’s aggregate average cost (AC), which was analysed following the Brazilian Ministry of Health’s micro-costing guidelines. The 1-year preintervention period evidenced an aggregated AC in adult, paediatric and neonatal ICUs, respectively, of Intl$21 763.5 (95% CI 20 683.6 to 22 843.0), Intl$34 062.4 (95% CI 25 819.6 to 42 304.9) and Intl$32 903.2 (95% CI 29 203.6 to 36 602.4) for CLABSI; Intl$25 202.5 (95% CI 24 276.6 to 26 127.8), Intl$44 753.6 and Intl$17 238.4 for VAP and Intl$19 166.3 (95% CI 17 676.2 to 20 656.1) and Intl$55 873.3 (95% CI 43 563.1 to 68 183.1) for CAUTI (not included neonatal ICUs). Primary outcome The cost savings were estimated using the HAIs prevented—expenses avoided—during the QI intervention period from September 2021 to December 2023. The HAIs prevented were estimated using the difference between observed and predicted infections based on the aggregated preintervention baseline. Results Of the 188 participating ICUs, 31 voluntarily completed and provided the requested financial data with 100% accuracy. Considering the prevented 7342 HAIs for adult, paediatric and neonatal ICUs, respectively: 1647, 86 and 205 CLABSI; 3775, 114 and 118 VAP; and 1377 and 20 CAUTI, we estimated a saving of Intl$175.3 million (95% CI 153.2 to 180.9 million) to the Brazilian unified health system and a resultant estimated return on investment (ROI) of 890%. Conclusion This QI collaborative is a value-based initiative preventing HAIs in adult, paediatric and neonatal ICUs in South American settings. The substantial cost savings and a remarkable ROI underscore the economic viability of investing in comprehensive QI infection prevention strategies.
