RESUMEN

INTRODUCTION: Adverse events in hospitals are prevented through risk reduction and reliable processes. Highly reliable hospitals are grounded by a robust patient safety culture with effective communication, leadership, teamwork, error reporting, continuous improvement, and organizational learning. Although hospitals regularly measure their patient safety culture for strengths and weaknesses, there have been no systematic reviews with meta-analyses reported from Latin America. PURPOSE: Our systematic review aims to produce evidence about the status of patient safety culture in Latin American hospitals from studies using the Hospital Survey on Patient Safety Culture (HSOPSC). METHODS: This systematic review was guided by the JBI guidelines for evidence synthesis. Four databases were systematically searched for studies from 2011 to 2021 originating in Latin America. Studies identified for inclusion were assessed for methodological quality and risk of bias. Descriptive and inferential statistics, including meta-analysis for professional subgroups and meta-regression for subgroup effect, were calculated. RESULTS: In total, 30 studies from five countries-Argentina (1), Brazil (22), Colombia (3), Mexico (3), and Peru (1)-were included in the review, with 10,915 participants, consisting primarily of nursing staff (93%). The HSOPSC dimensions most positive for patient safety culture were "organizational learning: continuous improvement" and "teamwork within units", while the least positive were "nonpunitive response to error" and "staffing". Overall, there was a low positive perception (48%) of patient safety culture as a global measure (95% CI, 44.53-51.60), and a significant difference was observed for physicians who had a higher positive perception than nurses (59.84; 95% CI, 56.02-63.66). CONCLUSIONS: Patient safety culture is a relatively unknown or unmeasured concept in most Latin American countries. Health professional programs need to build patient safety content into curriculums with an emphasis on developing skills in communication, leadership, and teamwork. Despite international accreditation penetration in the region, there were surprisingly few studies from countries with accredited hospitals. Patient safety culture needs to be a priority for hospitals in Latin America through health policies requiring annual assessments to identify weaknesses for quality improvement initiatives.

RESUMEN

Introducción: las enfermedades transmitidas por alimentos son una problemática mundial a la que la Organización Mundial de la Salud y los países brindan una atención especial. Dentro de los grupos de alto riesgo se encuentran los productos de origen animal, como la leche y sus derivados. Staphylococcus aureus es un microorganismo causante de brotes de las enfermedades transmitidas por alimentos, lo que genera la necesidad de estudiar la carga microbiana y establecer los controles adecuados. Objetivo: evaluar la calidad microbiológica en el proceso manufacturero en el área de producción de la Cooperativa de Producción Agropecuaria Chone LTDA, con el fin de asegurar la ausencia del Staphylococcus aureus en el queso fresco 100% chonero. Materiales y métodos: Se realizó un estudio de evaluación de la calidad en cuatro fases. Se realizaron exámenes microbiológicos iniciales, se identificaron las causas esenciales de contaminación identificadas por observación directa, revisión de documentos y entrevistas, como base para la elaboración e implementación de POE (Procedimientos Operativos Estandarizados) y POES (Procedimientos Operativos Estandarizados de Saneamiento). Se cumplieron los requerimientos éticos y se realizaron los análisis estadísticos utilizando porcentaje e índices como medida resumen y con el uso de IBM SPSS, versión libre, realizándose regresión logística binaria para determinar la probabilidad de éxito al aplicar dichos procedimientos. Resultados: los análisis microbiológicos iniciales (antes de implementación de POE y POES), dieron como resultado: 98, 116, 79, 120 y 13 UFC/g para las muestras: DiQ1, DiQ2, DiQ3, DiQ4 y DiQ5, respectivamente. Las causas esenciales de contaminación fueron falta de control microbiológico, falta de control del aspecto del personal y falta de control del agua) Una vez implementados los POE y POES, el análisis mostró ausencia en todas las muestras analizadas. Conclusiones: se concluye que la aplicación de POE y POES tiene un efecto significativo sobre la ausencia del Staphylococcus aureus, con probabilidad de éxito del 100% (AU).

Introduction: Diseases transmitted by foodstuffs (DTF) are a worldwide problem that receives special attention by WHO and different countries. High risk groups include foodstuff of animal origin, like milk and its by-products. Staphylococcus aureus is a microorganism responsible for DTF outbreaks which generates the necessity of studying its microbial burden and establishing the adequate controls. Objective: to evaluate the microbiological quality of the manufacturing process in the production area of the Farming and Stockbreeding Cooperative Chone LTDA, to assure the absence of Staphylococcus aureus in the manufacturing process of fresh cheese. Materials and methods: A study to assess the quality in four stages was carried out: initial microbiological tests, identification of the essential contamination causes by direct observation, documental review and inquires. They were used to elaborate and implement the Standardized Operational Procedures (SOP) and the Standardized Operational Procedures of Sanitation (SOPS). The ethical requirements were fulfilled and the statistical tests were performed using percentages and indexes as summary measures through IBM SPSS, free version; binary logistic regression was made to determine the success when applying those procedures. Results: initial microbiological controls (before implementing SOP and SOPS) gave these results 98, 116, 79, 120, and 13 UFC/g for samples DiQ1, DiQ2, DiQ3, DiQ4 and DiQ5 respectively. The main contamination causes were lack of microbiological control, lack of control on the staff's cleanliness and lack of control on the water. After implementing SOP and SOPS microbiological control found particularly clean samples. Conclusions: SOP and SOPS have a significant effect on the amount of Staphylococcus aureus, with 100% success probability (AU).
