Septic shock: Clinical indicators and implications to critical patient care.

AIMS AND OBJECTIVE: To identify clinical indicators of septic shock in critical care patients. BACKGROUND: The identification of clinical indicators of septic shock is relevant to avoid clinical deterioration of patients with sepsis. However, the recognition of these factors, especially by the nursing team, is still deficient and reinforces the need for studies that investigate the subject in different realities such as that of Brazil. DESIGN: The study had a cross-sectional design based on STROBE guidelines (see Appendix S1). METHODS: A sample of 392 patients with sepsis or septic shock was admitted to the Intensive Care Unit of a Brazilian university hospital. Data were collected from medical records of the Intrahospital Sepsis Combat Program referring to patients admitted between January 2018-January 2019. Sociodemographic and clinical data were collected, as well as information on the time from diagnosis of sepsis or septic shock to initiation of antibiotic therapy, length of stay, and discharge or death outcomes. Data were statically analysed. RESULTS: Out of the total sample, 190 (49%) patients were admitted with septic shock. Clinical indicators of septic shock were hypotension, mechanical ventilation, lactate levels between 2.0-3.9 or >4, hypothermia <36°C, radiotherapy-associated chemotherapy, Sequential Organ Failure Assessment score >3 and admittance through the emergency unit. Among patients with septic shock, 85 (44.7%) were discharged and 105 (55.2%) died in the intensive care unit. CONCLUSIONS: Patients with septic shock presented hyperlactataemia and greater organic dysfunction as clinical indicators when compared to patients with sepsis. Mechanical ventilation, chemotherapy and radiotherapy increased the risk of developing septic shock. RELEVANCE TO CLINICAL PRACTICE: Our results can support the nursing team by providing the main clinical indicators of septic shock and contributing to the interprofessional team in the prevention of septic shock.

Factors influencing physical functional status in intensive care unit survivors two years after discharge.

BACKGROUND: Studies suggest that in patients admitted to intensive care units (ICU), physical functional status (PFS) improves over time, but does not return to the same level as before ICU admission. The goal of this study was to assess physical functional status two years after discharge from an ICU and to determine factors influencing physical status in this population. METHODS: The study reviewed all patients admitted to two non-trauma ICUs during a one-year period and included patients with age ≥ 18 yrs, ICU stay ≥ 24 h, and who were alive 24 months after ICU discharge. To assess PFS, Karnofsky Performance Status Scale scores and Lawton-Instrumental Activities of Daily Living (IADL) scores at ICU admission (K-ICU and L-ICU) were compared to the scores at the end of 24 months (K-24mo and L-24mo). Data at 24 months were obtained through telephone interviews. RESULTS: A total of 1,216 patients were eligible for the study. Twenty-four months after ICU discharge, 499 (41.6%) were alive, agreed to answer the interview, and had all hospital data available. PFS (K-ICU: 86.6 ± 13.8 vs. K-24mo: 77.1 ± 19.6, p < 0.001) and IADL (L-ICU: 27.0 ± 11.7 vs. L-24mo: 22.5 ± 11.5, p < 0.001) declined in patients with medical and unplanned surgical admissions. Most strikingly, the level of dependency increased in neurological patients (K-ICU: 86 ± 12 vs. K-24mo: 64 ± 21, relative risk [RR] 2.6, 95% CI, 1.8-3.6, p < 0.001) and trauma patients (K-ICU: 99 ± 2 vs. K-24mo: 83 ± 21, RR 2.7, 95% CI, 1.6-4.6, p < 0.001). The largest reduction in the ability to perform ADL occurred in neurological patients (L-ICU: 27 ± 7 vs. L-24mo: 15 ± 12, RR 3.3, 95% CI, 2.3-4.6 p < 0.001), trauma patients (L-ICU: 32 ± 0 vs. L-24mo: 25 ± 11, RR 2.8, 95% CI, 1.5-5.1, p < 0.001), patients aged ≥ 65 years (RR 1.4, 95% CI, 1.07-1.86, p = 0.01) and those who received mechanical ventilation for ≥ 8 days (RR 1.48, 95% CI, 1.02-2.15, p = 0.03). CONCLUSIONS: Twenty-four months after ICU discharge, PFS was significantly poorer in patients with neurological injury, trauma, age ≥ 65 tears, and mechanical ventilation ≥ 8 days. Future studies should focus on the relationship between PFS and health-related quality of life in this population.
