Prolonged Capillary Refilling as a Predictor of Mortality in Patients With Septic Shock.

INTRODUCTION: Microcirculatory alterations characterize septic shock; increased blood lactate level has been described as markers of microcirculation alteration in patients with septic shock. Although useful, this serological analysis is not always feasible in all settings worldwide. OBJECTIVE: To determine if a prolonged capillary refilling is a predictor of mortality in patients with septic shock. METHODOLOGY: A 10-months prospective cohort study was carried out on 175 patients admitted to the Intensive Care Unit (ICU) with the diagnosis of septic shock. The capillary refilling time (CRT) was evaluated Immediately upon admission and after 6 hours post-resuscitation. Traditional tissue perfusion markers were also used to compare and analyze their predictive value on mortality at 28 days. RESULTS: The area under the ROC curve (AUC) to estimate mortality in patients with septic shock with CRT at admission was 0.666 (0.584-0.748), while at 6 hours was 0.819 (0.753-0.885), with a cut-off point of 4.5 seconds at admission (PPV 52.87% NPV 72.73%) and 3.5 sec at 6 hours (PPV 95.56% NPV 79.23%). In those with CRT > 3.5 seconds at 6 hours, they had a RR of 4.60, while a CRT > 4.5 seconds at admission had a RR of 1.94, with a non-survivor proportion of 95.56% for a CRT > 3.5 sec at 6 hours vs 20.77% for CRT ≤ 3.5 sec (P value < 0.001). The CRT at 6 hours showed significant differences in the survival curves with P-value < 0.001, where for values > 3.5 sec, survival at 28 days was 4.44% vs 79.20% for values ≤ 3.5 sec. CONCLUSION: CRT is a strong predictor of mortality in patients with septic shock. Evaluating changes in CRT during resuscitation from septic shock might be used as an important clinical tool to predict mortality; especially in low-resources settings where using other biomarkers might be sometimes difficult.

Attitudes and perceptions of medical doctors towards the local health system: a questionnaire survey in Ecuador.

BACKGROUND: Health systems worldwide rely on health professionals to deliver services and provide framework structures. Considering their opinions about their work environment, the public policies that regulate their work and the deficiencies of the health care system are key aspects of the governance within the system. The aim of this study was to assess the perceptions of Ecuadorian physicians about several aspects of the performance of the health delivery and monitoring systems locally. METHODS: A cross-sectional survey was performed in a group of physicians in Ecuador during 2017 using a self-selection sampling strategy. The participants were contacted by telephone, direct email or in person and asked to complete the online survey which contained 47 questions. RESULTS: A total of 607 full responses were received from physicians, where 68.6% of those had graduated within the last 17 years. 46.4% of respondents were medical specialists, 23.1% general practitioners, 10.0% rural health practitioners, 9.5% sub-specialists, 5.9% were formally enrolled in a specialty program and 5.1% were researchers or administrative physicians. Data analysis of the answers showed that approximately 62% of physician respondents in the study found their current workload at the time of the survey was unmanageable, the most common complaints about the Public Health system in the study being the amount of daily paperwork (78.4%), followed by a perceived lack of vision of the health authorities (60.1%) and the resource limitations within the public hospitals (53.5%). Additionally, 71.8% of respondents referred to limitations of the National Essential Medicines chart- especially on the availability of some drugs- and 57.5% of the respondents reported concerns about the quality of medicines available for treatment. CONCLUSIONS: The data provide basic inputs for health authorities regarding the functioning of the health system in Ecuador. Health professionals' concerns can be a valuable resource for monitoring and improving health system performance: however, there is a perceived sense of disconnection between the governance or management and the service delivery arms of the healthcare system in Ecuador. Whilst not representative of the entirety of the population of doctors, the study does give insight into where improvements to the health system might be made.
