  • Pediatric Mortality in a Rural Tertiary Care Center in Liberia

    Children (Basel)

    Little data exists on the more current post‐war and pre‐Ebola trends of child health in Liberia in the rural setting. This study is a retrospective chart review of pediatric mortality in 2013 at a rural tertiary care center in Liberia, 10 years post‐war. From January 2013 to December 2013, there were 50 pediatric deaths, or 5.4% of the 920 total pediatric admissions. The most common cause of neonatal death was sepsis, and the most common cause of death under five years of age was malaria. The…

This study is a retrospective chart review of pediatric mortality in 2013 at a rural tertiary care center in Liberia, 10 years post‐war. From January 2013 to December 2013, there were 50 pediatric deaths, or 5.4% of the 920 total pediatric admissions. The most common cause of neonatal death was sepsis, and the most common cause of death under five years of age was malaria. The majority (82.0%) of the deaths were in children under five. Pediatric mortality at this hospital was similar to other reported mortality six years post‐war, and lower than that reported immediately post‐war. Neonatal sepsis and malaria are two significant causes of pediatric mortality in this community and, therefore, further efforts to decrease childhood mortality should focus on these causes.

  • Anesthesia Practice and Perioperative Outcomes at 2 Tertiary Care Hospitals in Freetown, Sierra Leone

    Anesth Analg

    BACKGROUND: Anesthesia in West Africa is associated with high mortality rates. Critical shortages of adequately trained personnel, unreliable electrical supply, and lack of basic monitoring equipment are a few of the unique challenges to surgical care in this region. This study aims to describe the anesthesia practice at 2 tertiary care hospitals in Sierra Leone.

    METHODS: We conducted an observational study of anesthesia care at Connaught Hospital and Princess Christian Maternity…

    BACKGROUND: Anesthesia in West Africa is associated with high mortality rates. Critical shortages of adequately trained personnel, unreliable electrical supply, and lack of basic monitoring equipment are a few of the unique challenges to surgical care in this region. This study aims to describe the anesthesia practice at 2 tertiary care hospitals in Sierra Leone.

    METHODS: We conducted an observational study of anesthesia care at Connaught Hospital and Princess Christian Maternity Hospital in Freetown, Sierra Leone. Twenty-five percent of the anesthesia workforce in Sierra Leone, resident at both hospitals, was observed from June 2012 to February 2013. Perioperative assessments, anesthetic techniques, and intraoperative clinical and environmental irregularities were noted and analyzed. The postoperative status of observed cases was ascertained for morbidity and mortality.

    RESULTS: Between the 2 hospitals, 754 anesthesia cases and 373 general anesthetics were observed. Ketamine was the predominant IV anesthetic used. Both hospitals experienced infrastructural and environmental constraints to the delivery of anesthesia care during the observation period. Vital sign monitoring was irregular and dependent on age and availability of monitors. Perioperative mortality during the course of the study was 11.9 deaths/1000 anesthetics.

    CONCLUSIONS: We identified gaps in the application of internationally recommended anesthesia practices at both hospitals, likely caused by lack of available resources. Mortality rates were similar to those in other resource-limited countries.

  • Evaluation of a cardiopulmonary resuscitation curriculum in a low resource environment.

    Int J Med Educ

    Abstract
    OBJECTIVE:
    To evaluate whether a 2-day International Liaison Committee on Resuscitation (ILCOR) Universal Algorithm-based curriculum taught in a tertiary care hospital in Liberia increases local health care provider knowledge and skill comfort level.
    METHODS:
    A combined basic and advanced cardiopulmonary resuscitation (CPR) curriculum was developed for low-resource settings that included lectures and low-fidelity manikin-based simulations. In March 2014, the curriculum was…

    Abstract
    OBJECTIVE:
    To evaluate whether a 2-day International Liaison Committee on Resuscitation (ILCOR) Universal Algorithm-based curriculum taught in a tertiary care hospital in Liberia increases local health care provider knowledge and skill comfort level.
    METHODS:
    A combined basic and advanced cardiopulmonary resuscitation (CPR) curriculum was developed for low-resource settings that included lectures and low-fidelity manikin-based simulations. In March 2014, the curriculum was taught to healthcare providers in a tertiary care hospital in Liberia. In a quality assurance review, participants were evaluated for knowledge and comfort levels with resuscitation before and after the workshop. They were also videotaped during simulation sessions and evaluated on standardized performance metrics.
    RESULTS:
    Fifty-two hospital staff completed both pre-and post-curriculum surveys. The median score was 45% pre-curriculum and 82% post-curriculum (p<0.00001). The median provider comfort level score was 4 of 5 pre-curriculum and 5 of 5 post-curriculum (p<0.00001). During simulations, 93.2% of participants performed the pulse check within 10 seconds, and 97.7% performed defibrillation within 180 seconds.
    CONCLUSIONS:
    Clinician knowledge of and comfort level with CPR increased significantly after participating in our curriculum. A CPR curriculum based on lectures and low-fidelity manikin simulations may be an effective way to teach resuscitation in this low-resource setting.

  • Engaging staff to improve quality and safety in an austere medical environment: a case-control study in two Sierra Leonean hospitals.

    Int J Qual Health Care

    Abstract
    QUALITY PROBLEM OR ISSUE:
    Inadequate observance of basic processes in patient care such as patient monitoring and documentation practices are potential impediments to the timely diagnoses and management of patients. These gaps exist in low resource settings such as Sierra Leone and can be attributed to a myriad of factors such as workforce and technology deficiencies.

    Abstract
    QUALITY PROBLEM OR ISSUE:
    Inadequate observance of basic processes in patient care such as patient monitoring and documentation practices are potential impediments to the timely diagnoses and management of patients. These gaps exist in low resource settings such as Sierra Leone and can be attributed to a myriad of factors such as workforce and technology deficiencies.
    INITIAL ASSESSMENT:
    In the study site, only 12.4% of four critical vital signs were documented in the pre-intervention period.
    CHOICE OF SOLUTION:
    Implement a failure mode and effects analysis (FMEA) to improve documentation of four patient vital signs: temperature, blood pressure, pulse rate and respiratory rate.
    IMPLEMENTATION:
    FMEA was implemented among a subpopulation of health workers who are involved in monitoring and documenting patient vital signs. Pre- and post-FMEA monitoring and documentation practice were compared with a control site.
    EVALUATION:
    Participants identified a four-step process to monitoring and documenting vital signs, three categories of failure modes and four potential solutions. Based on 2100 patient days of documentation compliance data from 147 patients between July and November 2012, staff members at the study site were 1.79 times more likely to document all four patient vital signs in the post-implementation period (95% CI [1.35, 2.38]).
    LESSONS LEARNED:
    FMEA is a feasible and effective strategy for improving quality and safety in an austere medical environment. Documentation compliance improved at the intervention facility. To evaluate the scalability and sustainability of this approach, programs targeting the development of these types of process improvement skills in local staff should be evaluated.

  • Matching the Design of Anesthesia Life-support Equipment with Environmental Challenges

    Appropriate Healthcare Technologies for Low-Resource Settings (AHT 2014)

    Surgery is an essential component of health systems. Anesthesia is a necessity for the delivery of safe and effective surgical care. In emerging healthcare systems, anesthesia providers are often the only providers of life support, with the anesthesia machine being the tool most often used for this purpose. The use of anesthesia machines that are not designed to match existing constraints in low-resource environment places patients in these locations at risk of suffering cardiac or brain damage…

    Surgery is an essential component of health systems. Anesthesia is a necessity for the delivery of safe and effective surgical care. In emerging healthcare systems, anesthesia providers are often the only providers of life support, with the anesthesia machine being the tool most often used for this purpose. The use of anesthesia machines that are not designed to match existing constraints in low-resource environment places patients in these locations at risk of suffering cardiac or brain damage from anoxia and hypercapnia, awakening during surgery, or acquiring infectious diseases. These risks can be mitigated with appropriately designed equipment.
