Background: Patient safety culture is an important measure in assessing the quality of care. There is a growing need to establish a patient safety culture in hospitals. This study explored the perception of health professionals on patient safety culture in 2 public hospitals in Hanoi, Vietnam. Method: A mixed-methods study with an online Hospital Survey on Patient Safety Culture (HSOPSC) and qualitative data collection was conducted in Hanoi. The HSOPSC was validated in Vietnam before using it. Results: A total of 626 health professionals, including physicians and nurses, were involved in the survey, and 49 of them participated in in-depth interviews and focus group discussions. The average positive response of patient safety culture composites was high at 85.2% and varied from 49.4% to 97.9%. The strongest areas were teamwork within units (91.3%) and organizational learning/continuous improvement (88.4%), and the areas that needed improvement were staffing (49.4%) and nonpunitive response to error (53.1%). Conclusion:The centralized incident reporting, management with peer involvement on event reporting, and continuous quality improvement should be routinely embedded by hospital leaders down to unit managers and all staff.

IntroductionThis study aimed to evaluate portable functional near-infrared spectroscopy (fNIRS) device as an adjunct diagnostic tool in Vietnam to assess hemodynamics when people with schizophrenia and healthy controls performed cognitive tasks.MethodsOne hundred fifty-seven participants were divided into schizophrenia (n = 110) and healthy controls group (n = 47), which were recruited by match of age, and gender. Hemodynamic responses in the frontal cortex were monitored with a 48-channel portable device during the Stroop Color-Word Test (SCWT) and Verbal Fluency Test (VFT). General linear model compared the differences in oxyhemoglobin (HbO2) levels between the two groups. The Receiver Operating Characteristic (ROC) graph was generated for each neuroanatomical area.ResultsPeople with schizophrenia did not show significant activation in the frontal lobe during the SCWT and VFT as compared to pre-task. During the VFT, the area under the ROC curve of the bilateral dorsolateral prefrontal cortex, bilateral orbitofrontal cortex, bilateral frontopolar prefrontal cortex, and bilateral ventrolateral prefrontal cortex were greater than 0.7 (p < 0.001). The area under the ROC curve (AUC) for the right orbitofrontal cortex was maximal during the VFT (AUC = 0.802, 95%CI = 0.731–0.872). The Youden’s index reached a peak (0.57) at the optimal cut-point value (HbO2 cutoff <0.209 μmol/ml for schizophrenia) in which the sensitivity was 85%; specificity was 72%; positive predictive value (PPV) was 0.88; negative predictive value (NPV) was 0.68 and correct classification rate was 76%.DiscussionAssessing hemodynamics during VFT by portable fNIRS offers the potential as an adjunct diagnostic tool for schizophrenia in developing countries.
