Recommendations for sepsis management in resource-limited settings

PurposeTo provide clinicians practicing in resource-limited settings with a framework to improve the diagnosis and treatment of pediatric and adult patients with sepsis.MethodsThe medical literature on sepsis management was reviewed. Specific attention was paid to identify clinical evidence on sepsis management from resource-limited settings.ResultsRecommendations are grouped into acute and post-acute interventions. Acute interventions include liberal fluid resuscitation to achieve adequate tissue perfusion, normal heart rate and arterial blood pressure, use of epinephrine or dopamine for inadequate tissue perfusion despite fluid resuscitation, frequent measurement of arterial blood pressure in hemodynamically unstable patients, administration of hydrocortisone or prednisolone to patients requiring catecholamines, oxygen administration to achieve an oxygen saturation >90%, semi-recumbent and/or lateral position, non-invasive ventilation for increased work of breathing or hypoxemia despite oxygen therapy, timely administration of adequate antimicrobials, thorough clinical investigation for infectious source identification, fluid/tissue sampling and microbiological work-up, removal, drainage or debridement of the infectious source. Post-acute interventions include regular re-assessment of antimicrobial therapy, administration of antimicrobials for an adequate but not prolonged duration, avoidance of hypoglycemia, pharmacological or mechanical deep vein thrombosis prophylaxis, resumption of oral food intake after resuscitation and regaining of consciousness, careful use of opioids and sedatives, early mobilization, and active weaning of invasive support. Specific considerations for malaria, puerperal sepsis and HIV/AIDS patients with sepsis are included.ConclusionOnly scarce evidence exists for the management of pediatric and adult sepsis in resource-limited settings. The presented recommendations may help to improve sepsis management in middle- and low-income countries.

National intensive care unit bed capacity and ICU patient characteristics in a low income country

BackgroundPrimary health care delivery in the developing world faces many challenges. Priority setting favours HIV, TB and malaria interventions. Little is known about the challenges faced in this setting with regard to critical care medicine. The aim of this study was to analyse and categorise the diagnosis and outcomes of 1,774 patients admitted to a hospital intensive care unit (ICU) in a low-income country over a 7-year period. We also assessed the country’s ICU bed capacity and described the challenges faced in dealing with critically ill patients in this setting.FindingsA retrospective audit was conducted in a general ICU in a university hospital in Uganda. Demographic data, admission diagnosis, and ICU length of stay were recorded for the 1,774 patients who presented to the ICU in the period January 2003 to December 2009. Their mean age was 35.5 years. Males accounted for 56.5% of the study population; 92.8% were indigenous, and 42.9% were referrals from upcountry units. The average mortality rate over the study period was 40.1% (n = 715). The highest mortality rate (44%) was recorded in 2004 and the lowest (33.2%) in 2005. Children accounted for 11.6% of admissions (40.1% mortality). Sepsis, ARDS, traumatic brain injuries and HIV related conditions were the most frequent admission diagnoses. A telephonic survey determined that there are 33 adult ICU beds in the whole country.ConclusionsMortality was 40.1%, with sepsis, head injury, acute lung injury and HIV/AIDS the most common admission diagnoses. The country has a very low ICU bed capacity. Prioritising infectious diseases poses a challenge to ensuring that critical care is an essential part of the health care package in Uganda.

Surgery and anesthesia capacity-building in resource-poor settings: description of an ongoing academic partnership in Uganda.

BackgroundSurgery and perioperative care have been neglected in the arena of global health despite evidence of cost-effectiveness and the growing, substantial burden of surgical conditions. Various approaches to address the surgical disease crisis have been reported. This article describes the strategy of Global Partners in Anesthesia and Surgery (GPAS), an academically based, capacity-building collaboration between North American and Ugandan teaching institutions.MethodsThe collaboration’s projects shift away from the trainee exchange, equipment donation, and clinical service delivery models. Instead, it focuses on three locally identified objectives to improve surgical and perioperative care capacity in Uganda: workforce expansion, research, collaboration.ResultsRecruitment programs from 2007 to 2011 helped increase the number of surgery and anesthesia trainees at Mulago Hospital (Kampala, Uganda) from 20 to 40 and 2 to 19, respectively. All sponsored trainees successfully graduated and remained in the region. Postgraduate academic positions were created and filled to promote workforce retention. A local research agenda was developed, more than 15 collaborative, peer-reviewed papers have been published, and the first competitive research grant for a principal investigator in the Department of Surgery at Mulago was obtained. A local projects coordinator position and an annual conference were created and jointly funded by partnering international efforts to promote collaboration.ConclusionsSub-Saharan Africa has profound unmet needs in surgery and perioperative care. This academically based model helped increase recruitment of trainees, expanded local research, and strengthened stakeholder collaboration in Uganda. Further analysis is underway to determine the impact on surgical disease burden and other important outcome measures.

Modified Early Warning Score (MEWS) Identifies Critical Illness among Ward Patients in a Resource Restricted Setting in Kampala, Uganda: A Prospective Observational Study.

Introduction Providing optimal critical care in developing countries is limited by lack of recognition of critical illness and lack of essential resources. The Modified Early Warning Score (MEWS), based on physiological parameters, is validated in adult medical and surgical patients as a predictor of mortality. The objective of this study performed in Uganda was to determine the prevalence of critical illness on the wards as defined by the MEWS, to evaluate the MEWS as a predictor of death, and to describe additional risk factors for mortality. Methods We conducted a prospective observational study at Mulago National Referral Teaching Hospital in Uganda. We included medical and surgical ward patients over 18 years old, excluding patients discharged the day of enrolment, obstetrical patients, and patients who self-discharged prior to study completion. Over a 72-hour study period, we collected demographic and vital signs, and calculated MEWS; at 7-days we measured outcomes. Patients discharged prior to 7 days were assumed to be alive at study completion. Descriptive and inferential statistical analyses were performed. Results Of 452 patients, the median age was 40.5 (IQR 29–54) years, 53.3% were male, 24.3% were HIV positive, and 45.1% had medical diagnoses. MEWS ranged from 0 to 9, with higher scores representing hemodynamic instability. The median MEWS was 2 [IQR 1–3] and the median length of hospital stay was 9 days [IQR 4–24]. In-hospital mortality at 7-days was 5.5%; 41.4% of patients were discharged and 53.1% remained on the ward. Mortality was independently associated with medical admission (OR: 7.17; 95% CI: 2.064–24.930; p = 0.002) and the MEWS ≥ 5 (OR: 5.82; 95% CI: 2.420–13.987; p<0.0001) in the multivariable analysis. Conclusion There is a significant burden of critical illness at Mulago Hospital, Uganda. Implementation of the MEWS could provide a useful triage tool to identify patients at greatest risk of death. Future research should include refinement of MEWS for low-resource settings, and development of appropriate interventions for patients identified to be at high risk of death based on early warning scores.

International Surviving Sepsis Campaign guidelines 2016: the perspective from low-income and middle-income countries

www.thelancet.com/infection Vol 17 September 2017 893 pro grammes re-affirms the power of a multidisciplinary approach. A winning team knows that teamwork is what makes the dream work; clinicians, infection prevention professionals, pharmacists, microbiologists, nurses, and an ever-expanding number of health-care professionals involved at the clinical interface form a whole that is greater than the sum of its parts. Only five of the 32 studies included in Baur and colleagues’ meta-analysis were from low-income or middle-income countries, where multidisciplinary teams are rarely found outside of central hospitals. In these settings, we need to re-examine our perception of what an antibiotic stewardship programme looks like. The success of pharmacist-led stewardship programmes highlights a model that builds stewardship teams around this key cadre of health professional. And what of stewardship programmes at the community level? We need to look to non-traditional stewards, such as community health workers and members of the public, in settings where health-care professionals are a scarce resource. Non-traditional stewards need to join us in a partnership that looks beyond what can be offered in high-resource settings. Decreasing antibiotic resistance while preserving the effectiveness of antibiotics is the dream and antibiotic stewardship is the team captain. Baur and colleagues have provided the ammunition to convey this important message to antibiotic stewardship naysayers, policy makers, and stakeholders. The results of Baur and colleagues’ meta-analysis are an important advocacy tool, and one that we should use in support of developing winning teams. If we get antibiotic stewardship right, the real winner will be the patient who avoids infection by a drug-resistant bacterium or C difficile, now and in the future, as we preserve antibiotics for the generations to come.

Antibiotic prophylaxis for caesarean section at a Ugandan hospital: a randomised clinical trial evaluating the effect of administration time on the incidence of postoperative infections.

BackgroundProphylactic antibiotics are used to prevent postoperative infections after caesarean section. Studies have suggested that the timing of prophylaxis plays an important role. Over the years, the role of the anaesthesiologist in the administration of prophylactic antibiotics has become prominent. Therefore, there is an increasing need for anaesthesia providers to understand the rationale of antibiotic prophylaxis. We therefore sought to compare the effect of antibiotics prophylaxis within 1 hour before skin incision and after skin incision on the incidence of postoperative infections in patients undergoing caesarean section at Mulago Hospital.MethodsWe conducted a single-blind randomised clinical trial conducted at Mulago Hospital evaluating 464 patients undergoing emergency caesarean section. Patients were randomly assigned a group number that allocated them to either arm of the study. They received the same prophylactic antibiotic according to their allotment, that is, either within 1 hour before skin incision or after skin incision as per current standards of practice in Mulago Hospital. They were followed up to detect infection up to 10 days postoperatively. The primary outcome was postoperative infection. The data collected were analysed with STATA version 12 using univariate and bivariate analysis.ResultsThe risk of overall postoperative infection was significantly lower when prophylaxis was given within an hour before incision (RR O.77, 95% CI 0.62–0.97). We also found endometritis to be significantly reduced in the pre-incision group (RR 0.62; 95% CI 0.39–0.99; P value 0.036).ConclusionsGiving prophylactic antibiotics before skin incision reduces risk of postoperative infection, in particular of endometritis.Trial registrationPan African Clinical Trial Registry PACTR201311000610495.Date of trial registration: 12th August 2013.

Gender Parity in Critical Care Medicine

Clinical practice guidelines are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances. These documents inform and shape patient care around the world. In this Perspective we discuss the importance of diversity on guideline panels, the disproportionately low representation of women on critical care guideline panels, and existing initiatives to increase the representation of women in corporations, universities, and government. We propose five strategies to ensure gender parity within critical care medicine.

What’s new in sepsis recognition in resource-limited settings?

Sepsis is a life-threatening condition characterized by one or more organ dysfunctions due to a dysregulated host response to infection [1] or, in certain cases, due to direct pathogen effects. Sepsis is not only associated with bacterial or fungal infections but also with any other infection such as viral disease, protozoal (e.g., malaria), or tropical infections. Although the literature suggests that sepsis is predominantly a healthcare issue in resource-rich countries, the global burden of acute infections is highest in resource-limited areas [2]. Successful sepsis management relies on various components of which early recognition is essential. Evidence and recommendations for sepsis recognition are mainly based on research performed in resource-rich settings [3]. However, resource-rich and -limited countries differ in healthcare accessibility [4] and infectious disease epidemiology [5–7]. It is therefore unreasonable to directly translate evidence between these settings. The Global Intensive Care working group of the European Society of Intensive Care Medicine together with the Mahidol-Oxford Research Unit formed an international team of physicians to revise existent recommendations for sepsis management in resource-limited settings [8]. In this manuscript, we summarize recommendations on sepsis recognition. A detailed description of the guideline team, conflicts of interest, methods, rationales, and references is given in the Online supplement.

Ringer’s Lactate Versus Normal Saline in Urgent Cesarean Delivery in a Resource-Limited Setting: A Pragmatic Clinical Trial

BACKGROUND: Crystalloids are used routinely for perioperative fluid management in cesarean delivery. Few studies have determined the crystalloid of choice in obstetric anesthesia. We compared the effects of Ringer’s lactate (RL) versus 0.9% normal saline (NS) on maternal and neonatal blood pH and 24-hour postoperative morbidity in urgent cesarean delivery in a low-resource setting. Our hypothesis was that RL would result in 30% less acidosis than NS. METHODS: This was a pragmatic prospective double-blind randomized controlled trial in the Mulago National Referral Hospital Labor Ward Theater from September 2011 to May 2012. Five hundred parturients were studied; 252 were randomly assigned to NS and 248 to RL groups. Preoperative and postoperative maternal venous blood gases and placental umbilical arterial cord blood gases were analyzed. The primary outcome was incidence of maternal acidosis, as defined by a postoperative drop in venous pH below 7.32 or reduction in base excess below −3 in a previously normal parturient. Maternal 24-hour postoperative morbidity, neonatal pH, and neonatal base excess were the main secondary outcomes. The study was registered in ClinicalTrials.gov as NCT01585740. RESULTS: The overall incidence of maternal acidosis was 38% in NS and 29% in RL (relative risk, 1.29; 95% confidence interval, 1.01–1.66; P = .04). Thirty-two percent of parturients in NS experienced a drop in venous pH below 7.32 postoperatively, compared with 19% in RL (relative risk, 1.65; 95% confidence interval, 1.18–2.31; P = .003). The comparative drop in base excess postoperatively below −3 between the 2 groups was not statistically significant. There were no significant differences in the incidence of maternal 24-hour postoperative morbidity events and neonatal outcomes between the 2 groups. CONCLUSIONS: NS may be a safe choice for intraoperative fluid therapy in urgent cesarean delivery as RL, albeit with an increased incidence of metabolic acidosis.
