ObjectivesTo determine the prevalence of physical violence and threats against health workers and the aftermath in tertiary, secondary and primary care facilities in China.DesignA cross-sectional questionnaire study.Setting5 tertiary hospitals, 8 secondary hospitals and 32 primary care facilities located in both urban and rural areas of Zhejiang Province, China, were chosen as the study sites.ParticipantsA total of 4862 health workers who have contact with patients completed a survey from July 2016 to July 2017.Outcome measuresThe prevalence of physical violence, threats and Yi Nao, specific forms of physical violence and their aftermath were measured by a self-designed and verified questionnaire. Multivariable logistic regression models were used to examine the association between perceived organisational encouragement of reporting workplace violence (WPV) and physical violence, threats and Yi Nao after controlling for age, sex, level of facility, professional ranking and type of health worker.ResultsAmong all respondents, 224 (4.6%) were physically attacked and 848 (17.4%) experienced threats in the past year. Respondents in secondary hospitals were more likely to experience physical violence (AOR=3.29, 95% CI 2.21 to 4.89), threats (AOR=1.61, 95% CI 1.32 to 1.98) and Yi Nao (AOR=2.47, 95% CI 2.10 to 2.91), compared with primary care providers. Lack of organisational policies to report WPV was associated with higher likelihood of physical violence (AOR=3.64, 95% CI 2.57 to 5.18) and threats (AOR=2.21, 95% CI 1.76 to 2.78). Among physical violence cases, only 29.1% reported the attack to police mainly because most felt it useless to do so (58.8%). Only 25.7% were investigated and 72.4% of attackers received no punishment. Of all those attacked or threatened, 59.4% wanted to quit current post and 76.0% were fearful of dealing with urgent or severe cases.ConclusionsProper management of the aftermath of violence against health workers is inadequate. Formal guidelines for reporting and managing WPV are urgently needed.

Hydrolysis parameters (temperature, E/S ratio, pH, and time) for acid protease (from Aspergillus usamii) hydrolysis of wheat gluten were optimized by response surface methodology (RSM) using emulsifying activity index (EAI) as the response factor. A temperature of 48.9°C, E/S ratio of 1.60%, pH 3.0, hydrolysis time of 2.5 h was found to be the optimum condition to obtain wheat gluten hydrolysate with higher EAI. The solubility of wheat gluten was greatly improved by hydrolysis and became independent of pH over the studied range. Enzymatic hydrolysis resulted in dramatically increase in EAI, water and oil holding capacity. Molecular weight distribution results showed that most of the peptides above 10 kDa have been hydrolyzed into smaller peptides. The results of FTIR spectra and disulfide bond (SS) and sulfhydryl (SH) content suggested that a more extensional conformation was formed after hydrolysis, which could account for the improved functional properties.

Workplace violence (WPV) in the health sector is a global public health issue. The magnitude of WPV is a particular concern in China’s health system. To examine the potential causes of WPV, we analyzed 3,045 qualitative responses to an open-ended question in a survey with health workers in the Zhejiang province, China. We adapted a four-level socio-ecological framework (societal/systemic, community/organizational, interpersonal, and individual) to thematically analyze the data. Ten sub-themes emerged. Within the societal/systemic level, we identified three sub-themes: (a) lack of legislation against WPV, (b) suboptimal accessibility and affordability of health services due to maldistributed health resources, commercialized health services, and inadequate health insurance, and (c) unregulated mass media reports. Within the community/organizational level, three sub-themes emerged: (a) lack of supportive health facility leadership, (b) inaction by government authorities, and (c) inefficient law enforcement agencies. Within the interpersonal level, two sub-themes were identified: (a) poor provider–patient communication and (b) distrust between health workers and patients. Finally, we identified the personal characteristics of health workers (e.g., competence and professionalism) and patients (e.g., sociodemographic background and expectations/satisfaction) as two individual-level sub-themes. We recognized interactions among different levels. The weak state of Chinese legislation in this area and lack of high-level political will and guidance (societal/systemic) has left health facilities and law enforcement agencies (community/organizational) unclear about how to address WPV. The maldistribution of quality health resources (societal/systemic) has led to overcrowded outpatient clinics at higher-level care facilities (community/organizational). In light of the insufficient government funding and profit-oriented health services (societal/systemic), health workers were motivated to seek profits by providing unnecessary services, which compromised their professionalism (individual). Provider–patient relationships deteriorated (interpersonal), and patients sometimes held unrealistically high expectations associated with high medical expenses (individual). We propose multisectoral prevention strategies to address WPV in the health sector at all levels using a socio-ecological framework.
