Critical illness results in millions of deaths each year. Care for those with critical illness is often neglected due to a lack of prioritisation, co-ordination, and coverage of timely identification and basic life-saving treatments. To improve care, we propose a new focus on essential emergency and critical care (EECC)—care that all critically ill patients should receive in all hospitals in the world. Essential emergency and critical care should be part of universal health coverage, is appropriate for all countries in the world, and is intended for patients irrespective of age, gender, underlying diagnosis, medical specialty, or location in the hospital. Essential emergency and critical care is pragmatic and low-cost and has the potential to improve care and substantially reduce preventable mortality.

To investigate whether deranged physiologic parameters at admission to an ICU in Tanzania are associated with in-hospital mortality and compare single deranged physiologic parameters to a more complex scoring system. Prospective, observational cohort study of patient notes and admission records. Data were collected on vital signs at admission to the ICU, patient characteristics, and outcomes. Cutoffs for deranged physiologic parameters were defined a priori and their association with in-hospital mortality was analyzed using multivariable logistic regression. ICU at Muhimbili National Hospital, Dar es Salaam, Tanzania. All adults admitted to the ICU in a 15-month period. Two hundred sixty-nine patients were included: 54% female, median age 35 years. In-hospital mortality was 50%. At admission, 69% of patients had one or more deranged physiologic parameter. Sixty-four percent of the patients with a deranged physiologic parameter died in hospital compared with 18% without (p < 0.001). The presence of a deranged physiologic parameter was associated with mortality (adjusted odds ratio, 4.64; 95% CI, 1.95-11.09). Mortality increased with increasing number of deranged physiologic parameters (odds ratio per deranged physiologic parameter, 2.24 [1.53-3.26]). Every individual deranged physiologic parameter was associated with mortality with unadjusted odds ratios between 1.92 and 16.16. A National Early Warning Score of greater than or equal to 7 had an association with mortality (odds ratio, 2.51 [1.23-5.14]). Single deranged physiologic parameters at admission are associated with mortality in a critically ill population in a low-income country. As a measure of illness severity, single deranged physiologic parameters are as useful as a compound scoring system in this setting and could be termed "danger signs." Danger signs may be suitable for the basis of routines to identify and treat critically ill patients.

Global Critical Care is attracting increasing attention. At several million deaths per year, the worldwide burden of critical illness is greater than generally appreciated. Low income countries (LICs) have a disproportionally greater share of critical illness, and yet critical care facilities are scarce in such settings. Routines utilizing abnormal vital signs to identify critical illness and trigger medical interventions have become common in high-income countries but have not been investigated in LICs. The aim of the study was to assess whether the introduction of a vital signs directed therapy protocol improved acute care and reduced mortality in an Intensive Care Unit (ICU) in Tanzania. Prospective, before-and-after interventional study in the ICU of a university hospital in Tanzania. A context-appropriate protocol that defined danger levels of severely abnormal vital signs and stipulated acute treatment responses was implemented in a four week period using sensitisation, training, job aids, supervision and feedback. Acute treatment of danger signs at admission and during care in the ICU and in-hospital mortality were compared pre and post-implementation using regression models. Danger signs from 447 patients were included: 269 pre-implementation and 178 post-implementation. Acute treatment of danger signs was higher post-implementation (at admission: 72.9% vs 23.1%, p<0.001; in ICU: 16.6% vs 2.9%, p<0.001). A danger sign was five times more likely to be treated post-implementation (Prevalence Ratio (PR) 4.9 (2.9–8.3)). Intravenous fluids were given in response to 35.0% of hypotensive episodes post-implementation, as compared to 4.1% pre-implementation (PR 6.4 (2.5–16.2)). In patients admitted with hypotension, mortality was lower post-implementation (69.2% vs 92.3% p = 0.02) giving a numbers-needed-to-treat of 4.3. Overall in-hospital mortality rates were unchanged (49.4% vs 49.8%, p = 0.94). The introduction of a vital signs directed therapy protocol improved the acute treatment of abnormal vital signs in an ICU in a low-income country. Mortality rates were reduced for patients with hypotension at admission but not for all patients.

Aim: To determine the performance of plasma calprotectin as a marker of sepsis on intensive care unit (ICU) admission and as a marker of mortality day 30 post-ICU admission. Materials & methods: Consecutive ICU patients were allocated to: sepsis (n = 15), postoperative inflammation (n = 23) and intoxication without inflammation (n = 7) groups. Results: Calprotectin was 4.3 (2.6–8.2; mg/l; median [interquartile range]) in the sepsis, 2.8 (1.6–4.4) in the postoperative and 0.7 (0.4–1.6) in the intoxication groups. Area under the receiver operating characteristic curve for sepsis versus intoxication group was: 0.95, for sepsis versus postoperative groups: 0.65 and for survivors versus nonsurvivors: 0.70. Conclusion: Calprotectin was a sensitive marker of systemic inflammation, is a potential sepsis marker and performed well as mortality predictor in this pilot study.

Critical care saves lives of the young with reversible disease. Little is known about critical care services in low-income countries. In a setting with a shortage of doctors the actions of the nurse bedside are likely to have a major impact on the outcome of critically ill patients with rapidly changing physiology. Identification of severely deranged vital signs and subsequent treatment modifications are the basis of modern routines in critical care, for example goal directed therapy and rapid response teams. This study assesses how often severely deranged vital signs trigger an acute treatment modification on an Intensive Care Unit (ICU) in Tanzania. A medical records based, observational study. Vital signs (conscious level, respiratory rate, oxygen saturation, heart rate and systolic blood pressure) were collected as repeated point prevalences three times per day in a 1-month period for all adult patients on the ICU. Severely deranged vital signs were identified and treatment modifications within 1 h were noted. Of 615 vital signs studied, 126 (18%) were severely deranged. An acute treatment modification was in total indicated in 53 situations and was carried out three times (6%) (2/32 for hypotension, 0/8 for tachypnoea, 1/6 for tachycardia, 0/4 for unconsciousness and 0/3 for hypoxia). This study suggests that severely deranged vital signs are common and infrequently lead to acute treatment modifications on an ICU in a low-income country. There may be potential to improve outcome if nurses are guided to administer acute treatment modifications by using a vital sign directed approach. A prospective study of a vital sign directed therapy protocol is underway.

There are an estimated 19.4 million sepsis cases every year, many of them in low-income countries. The newly adopted definition of sepsis uses Sequential Organ Failure Assessment Score (SOFA), a score which is not feasible in many low-resource settings. A simpler quick-SOFA (qSOFA) based solely on vital signs score has been devised for identification of suspected sepsis. This study aimed to determine in-hospital prevalence and outcomes of sepsis, as defined as suspected infection and a qSOFA score of 2 or more, in two hospitals in Malawi. The secondary aim was to evaluate qSOFA as a predictor of mortality. A cross-sectional study of adult in-patients in two hospitals in Malawi was conducted using prospectively collected single-day point-prevalence data and in-hospital follow-up. Of 1,135 participants, 81 (7.1%) had sepsis. Septic patients had a higher hospital mortality rate (17.5%) than non-septic infected patients (9.0%, p = 0.027, odds ratio 2.1 [1.1–4.3]), although the difference was not statistically significant after adjustment for baseline characteristics. For in-hospital mortality among patients with suspected infection, qSOFA ≥ 2 had a sensitivity of 31.8%, specificity of 82.1%, a positive predictive value of 17.5%, and a negative predictive value of 91.0%. In conclusion, sepsis is common and is associated with a high risk of death in admitted patients in hospitals in Malawi. In low-resource settings, qSOFA score that uses commonly available vital signs data may be a tool that could be used for identifying patients at risk—both for those with and without a suspected infection.
