Injury in China: a systematic review of injury surveillance studies conducted in Chinese hospital emergency departments

Abstract

BackgroundInjuries represent a significant and growing public health concern in China. This Review was conducted to document the characteristics of injured patients presenting to the emergency department of Chinese hospitals and to assess of the nature of information collected and reported in published surveillance studies.MethodsA systematic search of MEDLINE and China Academic Journals supplemented with a hand search of journals was performed. Studies published in the period 1997 to 2007 were included and research published in Chinese was the focus. Search terms included emergency, injury, medical care.ResultsOf the 268 studies identified, 13 were injury surveillance studies set in the emergency department. Nine were collaborative studies of which eight were prospective studies. Of the five single centre studies only one was of a prospective design. Transport, falls and industrial injuries were common mechanisms of injury. Study strengths were large patient sample sizes and for the collaborative studies a large number of participating hospitals. There was however limited use of internationally recognised injury classification and severity coding indices.ConclusionDespite the limited number of studies identified, the scope of each highlights the willingness and the capacity to conduct surveillance studies in the emergency department. This Review highlights the need for the adoption of standardized injury coding indices in the collection and reporting of patient health data. While high level injury surveillance systems focus on population-based priority setting, this Review demonstrates the need to establish an internationally comparable trauma registry that would permit monitoring of the trauma system and would by extension facilitate the optimal care of the injured patient through the development of informed quality assurance programs and the implementation of evidence-based health policy.

A Survey of Wound Carein a Surgical Department in an Urban Clinical Setting in Northern Part of Nigeria

“…For many years, studies have shown that the relationship between age and relative risk of wound did not change [13]. In this survey, majority of the wounds belonged to the age groups (young-aged groups), followed by middle-age groups, these are the groups of people that are face with higher relative risk of open-wound injuries as well as a higher relative risk for both traumatic and non-traumatic musculoskeletal wounds similar to several other studies [1,14].…”

A pilot study of a hospital-based injury surveillance system in a secondary level district hospital in India: lessons learnt and way ahead

“…A systematic review of injury surveillance systems in China reported 12 studies all of whom showed male preponderance ranging fom 1.9:1 to 3.1:1 (Fitzharris et al 2011). Majority of the injuries belonged to the age group 25–44 followed by 45–64 similar to several other studies (Fitzharris et al 2011; Deng et al 2010).…”

“…A systematic review of injury surveillance systems in China reported 12 studies all of whom showed male preponderance ranging fom 1.9:1 to 3.1:1 (Fitzharris et al 2011). Majority of the injuries belonged to the age group 25–44 followed by 45–64 similar to several other studies (Fitzharris et al 2011; Deng et al 2010). This preponderance for adult males could be attributed to the fact that males in this age group tend to be more involved in outdoor occupations with wide ranging travel needs and other high risk activities (Holder et al 2001).…”

The effects of rest breaks, work shift start time, and sleep on the onset of severe injury among workers in the People’s Republic of China

“…As in many countries, work-related traumatic injuries are an important and preventable public health and economic concern in the People's Republic of China (PRC), and fatigue due to long work hours and shifts schedules within continuous operations has been suggested as a potential cause (1)(2)(3)(4). In a recent study of 3479 frontline workers in 60 factories over a two-year period (2008)(2009) in Shenzhen, China (4), 8.3% of all workers reported having a traumatic injury in the previous 12 months, and the strongest risk factors were working >55 hours per week [odds ratio (OR) 1.64, 95% confidence interval (95% CI) 1.21-2.22] and high mental work stress.…”
