ABSTRACT
BACKGROUND: Practical use of risk predictive tools and the assessment of their impact on outcome reduction is still a challenge. This pragmatic study of quality improvement (QI) describes the preoperative adoption of a customised postoperative death probability model (SAMPE model) and the evaluation of the impact of a Postoperative Anaesthetic Care Unit (PACU) pathway on the clinical deterioration of high-risk surgical patients. METHODS: A prospective cohort of 2,533 surgical patients compared with 2,820 historical controls after the adoption of a quality improvement (QI) intervention. We carried out quick postoperative high-risk pathways at PACU when the probability of postoperative death exceeded 5%. As outcome measures, we used the number of rapid response team (RRT) calls within 7 and 30 postoperative days, in-hospital mortality, and non-planned Intensive Care Unit (ICU) admission. RESULTS: Not only did the QI succeed in the implementation of a customised risk stratification model, but it also diminished the postoperative deterioration evaluated by RRT calls on very high-risk patients within 30 postoperative days (from 23% before to 14% after the intervention, p = 0.05). We achieved no survival benefits or reduction of non-planned ICU. The small group of high-risk patients (13% of the total) accounted for the highest proportion of RRT calls and postoperative death. CONCLUSION: Employing a risk predictive tool to guide immediate postoperative care may influence postoperative deterioration. It encouraged the design of pragmatic trials focused on feasible, low-technology, and long-term interventions that can be adapted to diverse health systems, especially those that demand more accurate decision making and ask for full engagement in the control of postoperative morbi-mortality.

Transarterial chemoembolization (TACE) and transarterial embolization (TAE) have improved the survival rates of patients with unresectable hepatocellular carcinoma (HCC); however, the optimal TACE/TAE embolic agent has not yet been identified. The aim of this study was to compare the effect of two different embolic agents such as microspheres (ME) and polyvinyl alcohol (PVA) on survival, tumor response, and complications in patients with HCC submitted to transarterial embolization (TAE). Eighty HCC patients who underwent TAE between June 2008 and December 2012 at a single center were retrospectively studied. A total of 48 and 32 patients were treated with PVA and ME, respectively. There were no significant differences in survival (P = 0.679) or tumoral response (P = 0.369) between groups (PVA or ME). Overall survival rates at 12, 18, 24, 36, and 48 months were 97.9, 88.8, 78.9, 53.4, and 21.4% in the PVA-TAE group and 100, 92.9, 76.6, 58.8, and 58% in the ME-TAE group (P = 0.734). Patients submitted to TAE with ME presented postembolization syndrome more frequently when compared with the PVA group (P = 0.02). According to our cohort, the choice of ME or PVA as embolizing agent had no significant impact on overall survival.
