Item Open Access A prospective neurosurgical registry evaluating the clinical care of traumatic brain injury patients presenting to Mulago National Referral Hospital in Uganda.(PloS one, 2017-01) Kuo, Benjamin J; Vaca, Silvia D; Vissoci, Joao Ricardo Nickenig; Staton, Catherine A; Xu, Linda; Muhumuza, Michael; Ssenyonjo, Hussein; Mukasa, John; Kiryabwire, Joel; Nanjula, Lydia; Muhumuza, Christine; Rice, Henry E; Grant, Gerald A; Haglund, Michael MBackground
Traumatic Brain Injury (TBI) is disproportionally concentrated in low- and middle-income countries (LMICs), with the odds of dying from TBI in Uganda more than 4 times higher than in high income countries (HICs). The objectives of this study are to describe the processes of care and determine risk factors predictive of poor outcomes for TBI patients presenting to Mulago National Referral Hospital (MNRH), Kampala, Uganda.Methods
We used a prospective neurosurgical registry based on Research Electronic Data Capture (REDCap) to systematically collect variables spanning 8 categories. Univariate and multivariate analysis were conducted to determine significant predictors of mortality.Results
563 TBI patients were enrolled from 1 June- 30 November 2016. 102 patients (18%) received surgery, 29 patients (5.1%) intended for surgery failed to receive it, and 251 patients (45%) received non-operative management. Overall mortality was 9.6%, which ranged from 4.7% for mild and moderate TBI to 55% for severe TBI patients with GCS 3-5. Within each TBI severity category, mortality differed by management pathway. Variables predictive of mortality were TBI severity, more than one intracranial bleed, failure to receive surgery, high dependency unit admission, ventilator support outside of surgery, and hospital arrival delayed by more than 4 hours.Conclusions
The overall mortality rate of 9.6% in Uganda for TBI is high, and likely underestimates the true TBI mortality. Furthermore, the wide-ranging mortality (3-82%), high ICU fatality, and negative impact of care delays suggest shortcomings with the current triaging practices. Lack of surgical intervention when needed was highly predictive of mortality in TBI patients. Further research into the determinants of surgical interventions, quality of step-up care, and prolonged care delays are needed to better understand the complex interplay of variables that affect patient outcome. These insights guide the development of future interventions and resource allocation to improve patient outcomes.Item Open Access An analysis of emergency care delays experienced by traumatic brain injury patients presenting to a regional referral hospital in a low-income country.(PloS one, 2020-01) Zimmerman, Armand; Fox, Samara; Griffin, Randi; Nelp, Taylor; Thomaz, Erika Bárbara Abreu Fonseca; Mvungi, Mark; Mmbaga, Blandina T; Sakita, Francis; Gerardo, Charles J; Vissoci, Joao Ricardo Nickenig; Staton, Catherine A; Staton, Catherine ABackground
Trauma is a leading cause of death and disability worldwide. In low- and middle-income countries (LMICs), trauma patients have a higher risk of experiencing delays to care due to limited hospital resources and difficulties in reaching a health facility. Reducing delays to care is an effective method for improving trauma outcomes. However, few studies have investigated the variety of care delays experienced by trauma patients in LMICs. The objective of this study was to describe the prevalence of pre- and in-hospital delays to care, and their association with poor outcomes among trauma patients in a low-income setting.Methods
We used a prospective traumatic brain injury (TBI) registry from Kilimanjaro Christian Medical Center in Moshi, Tanzania to model nine unique delays to care. Multiple regression was used to identify delays significantly associated with poor in-hospital outcomes.Results
Our analysis included 3209 TBI patients. The most common delay from injury occurrence to hospital arrival was 1.1 to 4.0 hours (31.9%). Most patients were evaluated by a physician within 15.0 minutes of arrival (69.2%). Nearly all severely injured patients needed and did not receive a brain computed tomography scan (95.0%). A majority of severely injured patients needed and did not receive oxygen (80.8%). Predictors of a poor outcome included delays to lab tests, fluids, oxygen, and non-TBI surgery.Conclusions
Time to care data is informative, easy to collect, and available in any setting. Our time to care data revealed significant constraints to non-personnel related hospital resources. Severely injured patients with the greatest need for care lacked access to medical imaging, oxygen, and surgery. Insights from our study and future studies will help optimize resource allocation in low-income hospitals thereby reducing delays to care and improving trauma outcomes in LMICs.Item Open Access Are Well-Informed Potential Trial Participants More Likely to Participate?(Journal of empirical research on human research ethics : JERHRE, 2017-12) de Oliveira, Lucas Lentini Herling; Vissoci, Joao Ricardo Nickenig; Machado, Wagner de Lara; Rodrigues, Clarissa G; Limkakeng, Alexander TBearing in mind the importance of the informed consent, flaws in this process may be a barrier to participants' recruitment. Our objective was to determine the relationship between the degree of comprehension of the informed consent document plus the importance given to individual elements by potential participants of a hypothetical trial and their willingness to participate in such trials. We performed an Online Survey simulating an emergency department trial recruitment, posteriorly evaluating participants' ratings of importance and self-assessed comprehension of specific topics of the informed consent document. Only 10% of the sample read the entire document. Some specific topics were associated with willingness to participate in the hypothetical trial, but simple composite additive scores of comprehension and importance were not. We concluded that participants in general do not read the entire informed consent document and that importance given to specific topics may influence willingness to participate.Item Open Access Availability of post-hospital services supporting community reintegration for children with identified surgical need in Uganda.(BMC health services research, 2018-09-20) Smith, Emily R; van de Water, Brittney J; Martin, Anna; Barton, Sarah Jean; Seider, Jasmine; Fitzgibbon, Christopher; Bility, Mathama Malakha; Ekeji, Nelia; Vissoci, Joao Ricardo Nickenig; Haglund, Michael M; Bettger, Janet PrvuBACKGROUND:Community services and supports are essential for children transitioning home to recover from the hospital after surgery. This study assessed the availability and geographic capacity of rehabilitation, assistive devices, familial support, and school reintegration programs for school-aged children in Uganda with identified surgical need. METHODS:This study assessed the geographic epidemiology and spatial analysis of resource availability in communities in Uganda. Participants were children with identified surgical need using the Surgeons OverSeas Assessment of Surgical need (SOSAS). Community-based resources available to children and adolescents after surgery in Uganda were identified using publicly available data sources and searching for resources through consultation with in-country collaborators We sought resources available in all geographic regions for a variety of services. RESULTS:Of 1082 individuals surveyed aged 5 to 14 yearsr, 6.2% had identified surgical needs. Pediatric surgical conditions were most prevalent in the Northern and Central regions of Uganda. Of the 151 community-based services identified, availability was greatest in the Central region and least in the Northern region, regardless of type. Assuming 30% of children with surgical needs will need services, a maximum of 50.1% of these children would have access to the needed services in the extensive capacity estimates, while only 10.0% would have access in the minimal capacity estimates. The capacity varied dramatically by region with the Northern region having much lower capacity in all scenarios as compared to the Central, Eastern, or Western regions. CONCLUSIONS:Our study found that beyond the city of Kampala in the Central region, community-based services were severely lacking for school-aged children in Uganda. Increased pediatric surgical capacity to additional hospitals in Uganda will need to be met with increased availability and access to community-based services to support recovery and community re-integration.Item Open Access Injury characteristics and their association with clinical complications among emergency care patients in Tanzania.(African journal of emergency medicine : Revue africaine de la medecine d'urgence, 2022-12) Zimmerman, Armand; Barcenas, Loren K; Pesambili, Msafiri; Sakita, Francis; Mallya, Simon; Vissoci, Joao Ricardo Nickenig; Park, Lawrence; Mmbaga, Blandina T; Bettger, Janet Prvu; Staton, Catherine ABackground
Over 5 million people annually die from injuries and millions more sustain non-fatal injuries requiring medical care. Ninety percent of injury deaths occur in low- and middle-income countries (LMICs). This study describes the characteristics, predictors and outcomes of adult acute injury patients presenting to a tertiary referral hospital in a low-income country in sub-Saharan Africa.Methods
This secondary analysis uses an adult acute injury registry from Kilimanjaro Christian Medical Centre (KCMC) in Moshi, Tanzania. We describe this patient sample in terms of socio-demographics, clinical indicators, injury patterns, treatments, and outcomes at hospital discharge. Outcomes include mortality, length of hospital stay, and functional independence. Associations between patient characteristics and patient outcomes are quantified using Cox proportional hazards models, negative binomial regression, and multivariable logistic regression.Results
Of all injury patients (n=1365), 39.0% were aged 30 to 49 years and 81.5% were men. Most patients had at least a primary school education (89.6%) and were employed (89.3%). A majority of injuries were road traffic (63.2%), fall (16.8%), or assault (14.0%) related. Self-reported comorbidities included hypertension (5.8%), HIV (3.1%), and diabetes (2.3%). Performed surgeries were classified as orthopedic (32.3%), general (4.1%), neurological (3.7%), or other (59.8%). Most patients reached the hospital at least four hours after injury occurred (53.9%). Mortality was 5.3%, median length of hospital stay was 6.1 days (IQR: 3.1, 15.0), self-care dependence was 54.2%, and locomotion dependence was 41.5%.Conclusions
Our study sample included primarily young men suffering road traffic crashes with delayed hospital presentations and prolonged hospital stays. Being older, male, and requiring non-orthopedic surgeries or having HIV portends a worse prognosis. Prevention and treatment focused interventions to reduce the burden of injury mortality and morbidity at KCMC are needed to lower injury rates and improve injury outcomes.Item Open Access Lifetime prevalence of intimate partner violence against women in an urban Brazilian city: A cross-sectional survey.(PloS one, 2019-01) Kwaramba, Tendai; Ye, Jinny J; Elahi, Cyrus; Lunyera, Joseph; Oliveira, Aline Chotte; Sanches Calvo, Paulo Rafael; de Andrade, Luciano; Vissoci, Joao Ricardo Nickenig; Staton, Catherine ABACKGROUND:Intimate partner violence is a global health burden that disproportionately affects women and their health outcomes. Women in Brazil are also affected by interpersonal violence. We aimed to estimate the lifetime prevalence of three forms of interpersonal violence against women (IPVAW) and to identify sociodemographic factors associated with IPVAW in one urban Brazilian city. METHODS:Using a cross-sectional design, we interviewed women aged ≥18 years in the urban Brazilian city, Maringá, who currently have or have had an intimate partner. The 13-item WHO Violence Against Women instrument was used to ask participants about their experiences with intimate partner violence, categorized into psychological, physical and sexual violence. We estimated associations between IPVAW and sociodemographic characteristics using generalized linear models. RESULTS AND CONCLUSIONS:Of the 419 women who were enrolled and met inclusion criteria, lifetime prevalence of IPVAW was 56%. Psychological violence was more prevalent (52%) than physical (21%) or sexual violence (13%). Twenty-eight women (6.4%) experienced all three forms of IPVAW. Women were more likely to experience violence if they were employed, did not live with their partner or had 4 or more children. Educational level, household income, age and race were not significantly associated factors. Our findings highlight a high prevalence of IPVAW in a community in southern Brazil.Item Open Access Population-level surgical rates and unmet need in India: a retrospective analysis of districts and states from 2011 to 2019.(International journal of surgery (London, England), 2024-03) Zadey, Siddhesh; Smith, Emily R; Staton, Catherine A; Fitzgerald, Tamara N; Vissoci, Joao Ricardo NickenigItem Open Access Prevention of childhood unintentional injuries in low- and middle-income countries: A systematic review.(PloS one, 2020-01) Tupetz, Anna; Friedman, Kaitlyn; Zhao, Duan; Liao, Huipeng; Isenburg, Megan Von; Keating, Elizabeth M; Vissoci, Joao Ricardo Nickenig; Staton, Catherine A; Staton, Catherine AInjuries are a leading cause of death and disability among children. Numerous injury prevention strategies have been successful in high-income countries, but the majority of unintentional injuries happen to children living in low- and middle-income countries (LMICs). This project aims to delineate the childhood injury prevention initiatives in LMICs. For inclusion, peer-reviewed articles needed to address unintentional injury, include children <18, assess a prevention-related intervention, contain a control group, and be published after 1988. Two pairs of reviewers evaluated articles independently to determine study eligibility. 74 articles were included. 30 studies addressed road traffic injuries, 11 drowning, 8 burns, 3 falls, 8 poisonings, and 21 an unspecified injury type. The findings show positive effects on injury outcome measures following educational interventions, the need for longer follow-up periods after the intervention, the need for effectiveness trials for behavior change, and the need for an increase in injury prevention services in LMICs. This is the first systematic review to summarize the prevention initiatives for all types of childhood unintentional injuries in LMICs. Increased attention and funding are required to go beyond educational initiatives with self-reported measures and little follow-up time to robust interventions that will reduce the global burden of unintentional injuries among children.Item Open Access Provision and Utilization of Team- and Community-Based Operative Care for Patients With Cleft Lip/Palate in North Carolina.(The Cleft palate-craniofacial journal : official publication of the American Cleft Palate-Craniofacial Association, 2020-11) Le, Elliot; Shrader, Peter; Bosworth, Hayden; Hurst, Jillian; Goldstein, Benjamin; Drake, Amelia; Wood, Jeyhan; David, Lisa R; Runyan, Christopher M; Vissoci, Joao Ricardo Nickenig; Harker, Matthew; Allori, Alexander CObjective
To characterize operative care for cleft lip and/or palate (CL/P) based on location (ie, from American Cleft Palate Craniofacial Association [ACPA]-approved multidisciplinary teams or from community providers).Design
Cross-sectional analysis of Healthcare Cost and Utilization Project State Inpatient Database and State Ambulatory Surgery & Services Database databases for North Carolina from 2012 to 2015.Setting/patients and main outcome measures
Clinical encounters for children with CL/P undergoing operative procedures were identified, classified by location as "Team" versus "Community," and characterized by demographic, geographic, clinical, and procedural factors. A secondary evaluation reviewed concordance of team and community practices with an ACPA guideline related to coordination of care.Results
Three teams and 39 community providers performed a total of 3010 cleft-related procedures across 2070 encounters. Teams performed 69.7% of total volume and performed the majority of cleft procedures, including cleft lip repair, palate repair, alveolar bone grafting, and correction of velopharyngeal insufficiency. Community locations principally offered myringotomy and rhinoplasty. Team care was associated with higher guideline concordance.Conclusions
American Cleft Palate Craniofacial Association -approved team-based care accounts for the majority of cleft-related care in North Carolina; however, a substantial volume of cleft-related procedures was provided by community providers, with 3 providers accounting for the vast majority of community cases.Item Open Access Validity and reliability of telephone administration of the patient-specific functional scale for the assessment of recovery from snakebite envenomation.(PLoS neglected tropical diseases, 2019-12-13) Theophanous, Rebecca G; Vissoci, Joao Ricardo Nickenig; Wen, Fan Hui; Griffin, S Michelle; Anderson, Victoria E; Mullins, Michael E; Brandehoff, Nicklaus P; Quackenbush, Eugenia B; Bush, Sean P; Toschlog, Eric A; Greene, Spencer C; Sharma, Kapil; Kleinschmidt, Kurt; Charlton, Nathan P; Rose, S Rutherfoord; Schwartz, Richard; Lewis, Brandon; Lavonas, Eric J; Gerardo, Charles JOBJECTIVES:Although more than 1.8 million people survive snakebite envenomation each year, their recovery is understudied. Obtaining long-term follow-up is challenging in both high- and low-resource settings. The Patient-Specific Functional Scale (PSFS) is an easily administered, well-accepted patient-reported outcome that is validated for assessing limb recovery from snakebite envenomation. We studied whether the PSFS is valid and reliable when administered by telephone. METHODS:This is a secondary analysis of data from a randomized clinical trial. We analyzed the results of PSFS collected in-person on days 3, 7, 14, 21, and 28 and by telephone on days 10, 17, and 24. We assessed the following scale psychometric properties: (a) content validity (ceiling and floor effects), (b) internal structure and consistency (Cronbach's alpha), and (c) temporal and external validity using Intraclass Correlation Coefficient (ICC). Temporal stability was assessed using Spearman's correlation coefficient and agreement between adjacent in-person and telephonic assessments with Cohen's kappa. Bland Altman analysis was used to assess differential bias in low and high score results. RESULTS:Data from 74 patients were available for analysis. Floor effects were seen in the early post-injury time points (median: 3 (IQR: 0, 5) at 3 days post-enrollment) and ceiling effects in the late time points (median: 9 (IQR: 8, 10). Internal consistency was good to excellent with both in-person (Cronbach α: 0.91 (95%CI 0.88, 0.95)) and telephone administration (0.81 (0.73, 0.89). Temporal stability was also good (ICC: 0.83 (0.72, 0.89) in-person, 0.80 (0.68, 0.88) telephone). A strong linear correlation was found between in-person and telephone administration (Spearman's ρ: 0.83 (CI: 0.78, 0.84), consistency was assessed as excellent (Cohen's κ 0.81 (CI: 0.78, 0.84), and Bland Altman analysis showed no systematic bias. CONCLUSIONS:Telephone administration of the PSFS provides valid, reliable, and consistent data for the assessment of recovery from snakebite envenomation.
