Patient Safety Culture: Current Status and Associated Factors Among Healthcare Workers at Kien An Hospital—Hai Phong, Vietnam—A Cross-Sectional Study

Objective: Patient safety culture (PSC) is a critical determinant of healthcare quality. This study aimed to assess the current status of PSC among healthcare workers at Kien An Hospital, Hai Phong, Vietnam, and identify associated factors. Methods: A cross-sectional survey was conducted using the 12-dimension hospital survey on patient safety culture (HSOPSC). A total of 324 healthcare professionals (physicians, nurses, and allied staff) participated. Data were analyzed using descriptive statistics and multivariable logistic regression. Results: The positive response rate (PRR) across the 12 dimensions of patient safety culture (PSC) varied widely. The highest positive perceptions were observed in “Teamwork within units” (98.5%) and “Teamwork across units” (98.1%). Conversely, severe vulnerabilities in psychological safety were identified, with “Communication Openness” recording the absolute lowest PRR at 25.9%, closely followed by “Non-punitive response to error” at 29.0%. Comparative analysis between professional strata revealed broad alignment across 11 dimensions, with the sole significant divergence occurring in “Feedback and communication about error”, where physicians reported a significantly higher PRR than nurses & allied staff (85.8% vs. 75.2%; p = 0.04). In the multivariable logistic regression model, age emerged as the single independent predictor of overall positive PSC; compared to early-career staff (<30 years), healthcare workers aged 30–40 years (AOR = 4.17, p = 0.02) and 40–50 years (AOR = 5.03, p = 0.02) had significantly higher odds of favorable safety perceptions. Conclusions: Healthcare workers at the study hospital exhibit exceptionally strong collaborative teamwork, yet low communication openness and the fear of a punitive environment remain critical systemic barriers to safety. Because safety culture challenges are macro-institutional and disproportionately impact junior personnel, interventions should shift away from role-specific policies. Instead, hospital leadership must prioritize establishing non-punitive reporting mechanisms, enhancing open dialogue, and designing targeted safety culture onboarding initiatives tailored specifically to the needs of early-career healthcare workers to foster continuous organizational learning.
