The effectiveness of emergency health care system on clinical signs in patients with sepsis
Abstract:
Sepsis is associated with high morbidity and mortality. In particular hypoperfusion is a poor prognostic marker of sepsis. While the clinical signs of vital organs can improve from sepsis therapy within 72 hours, many patients with sepsis presented the worse clinical signs during this time since arrival at emergency department. The previous research was limited to explain what factors of emergency health care system related to these situations. The purpose of this prospective descriptive correlational study was to explore factors in the system and patient levels influencing the clinical signs in patients with sepsis in the context of an emergency health care system. Two-stage random sampling was conducted to recruit 11 hospitals including 5 tertiary or regional hospitals and 6 general hospitals in central region of Thailand. Purposive sampling was conducted for 202 patients with sepsis during September 2014 to February 2015. The multilevel logistic regression was analyzed. The outcomes of clinical signs were deterioration (59.9%) and without deterioration (40.1%) between 6 72 hours since ED arrival. The 65.3% of patients who presented clinical signs with deterioration died. The results from multilevel logistic regression analysis demonstrated that a clustering effect influencing on clinical signs of patients with sepsis. The interaction effect models were not significant (all p > 0.05). The best model consisted of severity of illness ( = - 0.160, p < 0.001), level of hospital ( = 1.034 p = 0.007), and performance of sepsis resuscitation bundle ( = 2.235, p = 0.003). It was explained as follows; a one-unit increased in the severity of illness or MEDS score, the probability of clinical signs without deterioration between 6 72 hours since ED arrival decreased by 14.8%; the general hospital was more likely to promote the probability of clinical signs without deterioration between 6 72 hours since ED arrival by 2.813 times than tertiary or regional hospital; and patients who achieved in all components of medical treatment and non-invasive monitoring were more likely to promote the probability of clinical signs without deterioration between 6 72 hours since ED arrival by 9.349 times than patients who did not achieve. The contexts of emergency health care system influenced to clinical outcomes in patients with sepsis. The severity of illness related to delay access, the older age, and the history of health care utilization. The level of hospital, which was differentiated in workload and the situation of access block in emergency department, influenced the clinical outcomes differently. The performance of sepsis resuscitation bundle depended on triage practice, EMS utilization, and process of nursing care.
