RESUMEN

INTRODUCTION: Information on transfusion-associated outcomes is limited in sub-Saharan Africa. We sought to characterize predictors of mortality in transfused patients with acute care surgical conditions in Malawi. METHODS: We performed a retrospective propensity-matched analysis of patients with acute care surgical conditions at Kamuzu Central Hospital in Malawi from 2013 to 2021. We compared outcomes between patients who did and did not receive transfusions. RESULTS: A total of 7395 patients were included. Transfused patients (n = 1086) were older (median 43 y with interquartile range 30-59, versus 39 y [interquartile range 27-53] in the nontransfused group, P < 0.01), had a higher proportion of females (41% versus 27%, P < 0.01), presented earlier to the hospital (median 2.9 versus 3.7 d, P = 0.02), and with lower hemoglobin levels (27% versus 1% < 7 g/dL, P < 0.01). They had a lower rate of surgical intervention (48% versus 59%, P < 0.01) but a higher rate of complications (62% versus 33%, P < 0.01). Crude in-hospital mortality was 25.5% for the transfused group and 12.8% for the nontransfused group (P < 0.01). After propensity matching, transfused patients had three times the odds of mortality compared to nontransfused patients (odds ratio 3.3, 95% confidence interval 2.3, 4.8). CONCLUSIONS: In this propensity-matched study, transfused surgical patients were more likely to experience in-hospital mortality. These results suggest that the transfusion requirement reflects critical illness and warrants further investigation in this low-resource setting.

RESUMEN

INTRODUCTION: Functional decline is associated with critical illness, though this relationship in surgical patients is unclear. This study aims to characterize functional decline after intensive care unit (ICU) admission among surgical patients. METHODS: We performed a retrospective analysis of surgical patients admitted to the ICU in the Cerner Acute Physiology and Chronic Health Evaluation database, which includes 236 hospitals, from 2007 to 2017. Patients with and without functional decline were compared. Predictors of decline were modeled. RESULTS: A total of 52,838 patients were included; 19,310 (36.5%) experienced a functional decline. Median ages of the decline and nondecline groups were 69 (interquartile range 59-78) and 63 (interquartile range 52-72) years, respectively (P < 0.01). The nondecline group had a larger proportion of males (59.1% versus 55.3% in the decline group, P < 0.01). After controlling for sociodemographic covariates, comorbidities, and disease severity upon ICU admission, patients undergoing pulmonary (odds ratio [OR] 6.54, 95% confidence interval [CI] 2.67-16.02), musculoskeletal (OR 4.13, CI 3.51-4.87), neurological (OR 2.67, CI 2.39-2.98), gastrointestinal (OR 1.61, CI 1.38-1.88), and skin and soft tissue (OR 1.35, CI 1.08-1.68) compared to cardiovascular surgeries had increased odds of decline. CONCLUSIONS: More than one in three critically ill surgical patients experienced a functional decline. Pulmonary, musculoskeletal, and neurological procedures conferred the greatest risk. Additional resources should be targeted toward the rehabilitation of these patients.

RESUMEN

INTRODUCTION: Electrical injuries can be devastating, and data is lacking in low-resource settings. We aimed to identify predictors of mortality following electrical and lightning injuries (ELI) in Malawi. METHODS: We performed a retrospective observational study of patients presenting with ELI and burn injuries at a tertiary hospital in Malawi from 2011 to 2020. Outcomes were compared and predictors of mortality were modeled. RESULTS: A total of 382 ELI and 6371 burn patients were included. The mean ages for ELI and burn groups were 24 ± 14 and 11 ± 14 years, respectively (p < 0.01). Most patients were injured at home (91% in the burn group versus 51% in the ELI group, p < 0.01). The crude mortality rate in the ELI group was 28%, compared to 12% in the burn group (p < 0.01). On multivariate logistic regression, predictors of mortality included ELI (odds ratio [OR] 13.3, 95% confidence interval [CI] 7.2-24.5) and total body surface area burned (OR 1.1, 95% CI 1.1-1.1). Predicted mortality for ELI has increased over time (p = 0.05). CONCLUSIONS: ELI confers more than 13 times higher odds of mortality than burn injuries in Malawi, with mortality risk increasing over time. More efforts are needed to prevent electrical hazards and implement timely interventions for patients with ELI.

RESUMEN

BACKGROUND: Defining the optimal timing of operative intervention for pediatric burn patients in a resource-limited environment is challenging. We sought to characterize the association between mortality and the timing of operative intervention at a burn center in Lilongwe, Malawi. METHODS: This is a retrospective analysis of burn patients (<18 years old) presenting to Kamuzu Central Hospital from 2011 to 2022. We compared patients who underwent excision and/or burn grafting based on the timing of the operation. We used logistic regression modeling to estimate the adjusted odds ratio of death based on the timing of surgery. RESULTS: We included 2502 patients with a median age of 3 years (IQR 1-5) and a male preponderance (56.8%). 411 patients (16.4%) had surgery with a median time to surgery of 18 days (IQR 8-34). The crude mortality rate among all patients was 17.0% and 9.1% among the operative cohort. The odds ratio of mortality for patients undergoing surgery within 3 days from presentation was 5.00 (95% CI 2.19, 11.44) after adjusting for age, sex, % total burn surface area (TBSA), and flame burn. The risk was highest for the youngest patients. CONCLUSIONS: Children who underwent burn excision and/or grafting in the first 3 days of hospitalization had a much higher risk of death than patients undergoing surgical intervention later. Delaying operative intervention till >72 h for pediatric patients, especially those under 5 years old, may confer a survival advantage. More investment is needed in early resuscitation and monitoring for this patient population.

RESUMEN

BACKGROUND: Arrhythmias are common in critically ill patients, though the impact of arrhythmias on surgical patients is not well delineated. We aimed to characterize mortality following arrhythmias in critically ill patients. METHODS: We performed a propensity-matched retrospective analysis of intensive care unit (ICU) patients from 2007 to 2017 in the Cerner Acute Physiology and Chronic Health Evaluation database. We compared outcomes between patients with and without arrhythmias and those with and without surgical indications for ICU admission. We also modeled predictors of arrhythmias in surgical patients. RESULTS: 467,951 patients were included; 97,958 (20.9%) were surgical patients. Arrhythmias occurred in 1.4% of the study cohorts. Predictors of arrhythmias in surgical patients included a history of cardiovascular disease (odds ratio [OR] 1.35, 95% confidence interval [CI95] 1.11-1.63), respiratory failure (OR 1.48, CI95 1.12-1.96), pneumonia (OR 3.17, CI95 1.98-5.10), higher bicarbonate level (OR 1.03, CI95 1.01-1.05), lower albumin level (OR 0.79, CI95 0.68-0.91), and vasopressor requirement (OR 27.2, CI95 22.0-33.7). After propensity matching, surgical patients with arrhythmias had a 42% mortality risk reduction compared to non-surgical patients (risk ratio [RR] 0.58, CI 95 0.43-0.79). Predicted probabilities of mortality for surgical patients were lower at all ages. CONCLUSIONS: Surgical patients with arrhythmias are at lower risk of mortality than non-surgical patients. In this propensity-matched analysis, predictors of arrhythmias in critically ill surgical patients included a history of cardiovascular disease, respiratory complications, increased bicarbonate levels, decreased albumin levels, and vasopressor requirement. These findings highlight the differential effect of arrhythmias on different cohorts of critically ill populations.

RESUMEN

INTRODUCTION: Trauma scoring systems provide valuable risk stratification of injured patients. Trauma scoring systems developed in resource-limited settings, such as the Malawi Trauma Score (MTS), are based on readily available clinical information. This study sought to test the performance of the MTS in a United States trauma population. MATERIALS AND METHODS: We analyzed the United States National Trauma Data Bank during 2017-2020. MTS uses alertness score: alert, responds to verbal or painful stimuli, or unresponsive (AVPU), age, sex, presence of a radial pulse, and primary anatomic injury location. MTS and an age-adjusted version reflective of the US age distribution, was evaluated for its performance in predicting crude mortality in the National Trauma Data Bank using receiver operating characteristic analysis. We utilized logistic regression to model the odds ratio of death at a particular MTS cutoff. RESULTS: A total of 3,833,929 patients were included. The mean age was 49.3 y (sandard deviation 24.4), with a male preponderance (61.1%). Crude mortality was 3.4% (n = 131,452/3,833,929). The area under the curve for the MTS in predicting mortality was 0.87 (95% CI 0.87, 0.88). The area under the curve for a cutoff of 15 was 0.83 (95% CI 0.83, 0.83). An MTS of 15 higher had an odds ratio of death of 46.5 (95% CI 45.9, 47.1), compared to those with a score of 14 or lower. CONCLUSIONS: MTS has excellent performance as a predictor of mortality in a US trauma population. MTS is simple to calculate and can be estimated in the prehospital setting or the emergency department. Consequently, it may have utility as a triage tool in both high-income trauma systems and resource-limited settings.

RESUMEN

BACKGROUND: Pediatric injuries contribute to substantial mortality and morbidity worldwide, particularly in sub-Saharan Africa. We aim to identify predictors of mortality and time trends for pediatric traumatic brain injuries (TBIs) in Malawi. METHODS: We performed a propensity-matched analysis of data from the trauma registry at Kamuzu Central Hospital in Malawi from 2008 to 2021. All children ≤16 years of age were included. Demographic and clinical data were collected. Outcomes were compared between patients with and without head injuries. RESULTS: A cohort of 54,878 patients was included, with 1755 having TBI. The mean ages of patients with and without TBI were 7.8 ± 7.8 years and 7.1 ± 4.5 years, respectively. The most common mechanism for patients with and without TBI was road traffic injury and falls, respectively (48.2% vs. 47.8%, P < 0.01). The crude mortality rate for the TBI cohort was 20.9% compared to 2.0% in the non-TBI cohort (P < 0.01). After propensity matching, patients with TBI had 4.7 higher odds of mortality (95% confidence interval 1.9-11.8). Over time, patients with TBI had an increasing predicted probability of mortality for all age categories, with the most significant increase among children younger than 1 year. CONCLUSIONS: TBI confers a greater than 4-fold higher likelihood of mortality in this pediatric trauma population in a low-resource setting. These trends have worsened over time.

RESUMEN

BACKGROUND: Advances in trauma care in high-income countries have significantly reduced late deaths following trauma, challenging the classical trimodal pattern of trauma-associated mortality. While studies from low and middle-income countries have demonstrated that the trimodal pattern is still occurring in many regions, there is a lack of data from sub-Saharan Africa evaluating the temporal epidemiology of trauma deaths. METHODS: We conducted a retrospective analysis of the trauma registry at Kamuzu Central Hospital in Lilongwe, Malawi, including all injured patients presenting to the emergency department (ED) from 2009 to 2021. Patients were compared based on timing of death relative to time of injury. We then used a modified Poisson regression model to identify adjusted predictors for early mortality compared to late mortality. RESULTS: Crude mortality of patients presenting to the ED in the study period was 2.4% (n = 4,096/165,324). Most patients experienced a pre-hospital death (n = 2,330, 56.9%), followed by death in the ED (n = 619, 15.1%). Early death (pre-hospital or ED) was associated with transportation by police (RR1.52, 95% CI 1.38, 1.68) or private vehicle (RR1.20, 95% CI 1.07, 1.31), vehicle-related trauma (RR1.10, 95% CI 1.05, 1.14), and penetrating injury (RR1.11, 95% CI 1.04, 1.19). Ambulance transportation was associated with a 40% decrease in the risk of early death. CONCLUSIONS: At a busy tertiary trauma center in Malawi, most trauma-associated deaths occur within 48 h of injury, with most in the pre-hospital setting. To improve clinical outcomes for trauma patients in this environment, substantial investment in pre-hospital care is required through first-responder training and EMS infrastructure.

RESUMEN

BACKGROUND: Fall-related injury (FRI) is a leading cause of injuries worldwide. Data on injury patterns and trends over time are lacking in resource-limited settings. METHODS: We performed a retrospective analysis of FRI at Kamuzu Central Hospital in Malawi from 2009 to 2021. Outcomes were compared between patients presenting with FRI and those with other injury mechanisms. Bivariate and multivariate regressions were used to determine predictors of presentation following falls and mortality. We also analyzed time trends. RESULTS: A total of 166,047 patients were included, of which 41,695 were patients presenting after falls (25.7%). Most FRI patients were between 5 and 45 (67.2%) and male (66.9%). Most falls occurred at home (67.3%) and resulted in extremity injuries (51.6%). The predicted probability of hospital presentation after falling is highest for children ≤ 5 years and adults > 60 years and decreases over time. On multivariate analysis, patients between 5 and 15 [adjusted odds ratio (AOR) 1.70, 95% confidence interval (CI) 1.63-1.77] and > 60 (AOR 1.14, 95% CI 1.07-1.22) and women (AOR 1.13, 95% CI 1.10-1.16) are more likely to present with FRI. Compared to patients with non-FRI, those with FRI were more likely to have been injured at school (AOR 2.16, 95% CI 2.01-2.32) and during sports and recreation (AOR 4.53, 95% CI 4.24-4.85). CONCLUSION: FRI is the most common injury presentation after motor vehicle injury in this low-resource setting. This study provides essential information about FRI in Malawi over time. Our findings can help inform resource allocation and injury prevention initiatives.

RESUMEN

BACKGROUND: Mortality from perforated peptic ulcer disease (PUD) remains high, especially in sub-Saharan Africa. We sought to identify predictors of mortality following surgery for perforated PUD. METHODS: We performed a retrospective study of acute care surgeries at Kamuzu Central Hospital (KCH) in Malawi from 2013 to 2022. Patients undergoing omental patch surgeries were included. Bivariate and multivariate analyses were used to model predictors of mortality. RESULTS: A total of 248 patients were included. The mean age was 30 ± 15 years. Ninety percent were male. Mortality rate was 22.2%. Predictors of mortality included age (adjusted odds ratio [AOR] 1.06, 95% confidence interval [CI] 1.03-1.09), shock index (AOR 1.86, 95% CI 1.14-3.03), days to operative intervention (AOR 1.44, 95% CI 1.10-1.88), and presence of complications (AOR 9.65, 95% CI 3.79-24.6). CONCLUSIONS: Mortality following surgery for perforated PUD remains high in this low-resource environment. In-hospital delay is a significant and modifiable predictor of mortality.

RESUMEN

BACKGROUND: Preventable surgical errors of varying degrees of physical, emotional, and financial harm account for a significant number of adverse events. These errors are frequently tied to systemic problems within a health care system, including the absence of necessary policies/procedures, obstructive cultural hierarchy, and communication breakdown between staff. We developed an innovative, theory-based virtual reality (VR) training to promote understanding and sensemaking toward the holistic view of the culture of patient safety and high reliability. OBJECTIVE: We aim to assess the effect of VR training on health care workers' (HCWs') understanding of contributing factors to patient safety events, sensemaking of patient safety culture, and high reliability organization principles in the laboratory environment. Further, we aim to assess the effect of VR training on patient safety culture, TeamSTEPPS behavior scores, and reporting of patient safety events in the surgery department of an academic medical center in the clinical environment. METHODS: This mixed methods study uses a pre-VR versus post-VR training study design involving attending faculty, residents, nurses, technicians of the department of surgery, and frontline HCWs in the operation rooms at an academic medical center. HCWs' understanding of contributing factors to patient safety events will be assessed using a scale based on the Human Factors Analysis and Classification System. We will use the data frame theory framework, supported by a semistructured interview guide to capture the sensemaking process of patient safety culture and principles of high reliability organizations. Changes in the culture of patient safety will be quantified using the Agency for Healthcare Research and Quality surveys on patient safety culture. TeamSTEPPS behavior scores based on observation will be measured using the Teamwork Evaluation of Non-Technical Skills tool. Patient safety events reported in the voluntary institutional reporting system will be compared before the training versus those after the training. We will compare the Agency for Healthcare Research and Quality patient safety culture scores and patient safety events reporting before the training versus those after the training by using descriptive statistics and a within-subject 2-tailed, 2-sample t test with the significance level set at .05. RESULTS: Ethics approval was obtained in May 2021 from the institutional review board of the University of North Carolina at Chapel Hill (22-1150). The enrollment of participants for this study will start in fall 2022 and is expected to be completed by early spring 2023. The data analysis is expected to be completed by July 2023. CONCLUSIONS: Our findings will help assess the effectiveness of VR training in improving HCWs' understanding of contributing factors of patient safety events, sensemaking of patient safety culture, and principles and behaviors of high reliability organizations. These findings will contribute to developing VR training to improve patient safety culture in other specialties.

RESUMEN

Women with small HER2+ breast cancers may have excellent prognosis with adjuvant single-agent chemotherapy and HER2-targeted therapy. The role of de-escalated therapy in the neoadjuvant setting, however, remains uncertain. We conducted a cohort study of adult women with T1-2/cN0 HER2+ breast cancer diagnosed 2013-2016 in the National Cancer Database treated with neoadjuvant chemotherapy (NAC) and HER2-targeted therapy. Factors associated with pathologic complete response (pCR) and overall survival were examined. In total, 6994 patients were included, 32% cT1 and 68% cT2. Multi-agent NAC was given to 90% of women while single-agent NAC was given to 10% of women. pCR was achieved in 46% of cT2 patients and 43% of cT1, and in 46% of patients treated with multi-agent versus 38% single agent. Patients receiving multi-agent chemotherapy were younger, had fewer comorbidities, and had higher cT stage and grade. In all patients, pCR was associated with improved survival (p < 0.01). Multi-agent chemotherapy (OR 1.3, p = 0.003), hormone receptor negative (OR 2.6, p < 0.001), higher grade (OR 2.2, p < 0.001), younger age (OR 1.4, p = 0.011), and later year of diagnosis (OR 1.3, p = 0.005) were associated with achieving pCR. Multi-agent chemotherapy was associated with higher likelihood of pCR, but this effect was modest compared to other factors. Single-agent NAC with HER2-directed therapy in selected patients may provide excellent outcome with reduced toxicity, while allowing escalated therapy in the adjuvant setting for patients with residual disease. Prospective studies are needed to determine effects of de-escalation in the neoadjuvant setting on survival and optimal selection strategies.

RESUMEN

BACKGROUND: The optimal treatment strategy for small node-negative human epidermal growth factor receptor 2-positive (HER2+) breast cancer remains controversial. Neoadjuvant chemotherapy may risk overtreatment, whereas surgery first fails to identify patients with residual disease in need of escalated adjuvant systemic therapy. We investigated patient characteristics associated with receipt of neoadjuvant chemotherapy. METHODS: Adult women with cT1-T2/N0, HER2+ breast cancer between 2013 and 2017 in the National Cancer Database who underwent surgery within 8 months of diagnosis were included. Patients were classified as receiving neoadjuvant chemotherapy versus a surgery-first approach. We assessed the sociodemographic and clinical predictors of neoadjuvant chemotherapy versus surgery first and associations between neoadjuvant chemotherapy and breast cancer treatments using multivariable regression models. RESULTS: We identified 56,784 women, of whom 12,758 (22%) received neoadjuvant chemotherapy, 29,139 (53%) received adjuvant chemotherapy, 12,907 (24%) received no chemotherapy, and 1980 were missing chemotherapy information. After adjustment, cT2 stage was the strongest predictor of neoadjuvant chemotherapy compared with surgery first. Younger age and later diagnosis year were positively associated with receipt of neoadjuvant chemotherapy. In contrast, hormone receptor positivity, Black race, rural county, and government-funded or no health insurance were inversely associated with neoadjuvant chemotherapy. In multivariable analyses, patients who received neoadjuvant chemotherapy were more likely to have a mastectomy (vs. lumpectomy) and sentinel lymph node biopsy or no nodal surgery (vs. axillary lymph node dissection). Patients who received neoadjuvant chemotherapy were more likely to receive multi-agent (vs. single-agent) chemotherapy than those who received adjuvant chemotherapy. CONCLUSIONS: Substantial differences in the utilization of neoadjuvant chemotherapy exist in women with HER2+ breast cancer, which reflect both clinical parameters and disparities. Optimal treatment strategies should be implemented equitably across sociodemographic groups.

RESUMEN

INTRODUCTION: Despite the ubiquity of motorized vehicular transport, non-motorized transportation continues to be common in sub-Saharan Africa. METHODS: We performed a retrospective analysis of trauma patients presenting to Kamuzu Central Hospital in Malawi from February 2008 to May 2018. Demographic and clinical variables including injury characteristics and outcomes were collected. We performed bivariate and multivariate logistic regression to determine predictors of mortality following non-motorized vehicular trauma. RESULTS: This study included 36,412 patients involved in vehicular road injuries. Patients in the non-motorized group had a preponderance of men (84% versus 73%, p<0.01). The proportion of patients with Glasgow Coma Scale > 8 was slightly higher in the non-motorized group (99% versus 98%, p<0.01), though injury severity did not differ significantly between the two groups. A higher proportion in the motorized group had the most severe injury of contusions and abrasions (56% versus 50%, p<0.01). In contrast, the non-motorized group had a higher proportion of orthopedic injuries (24% versus 16%, p<0.01). The crude mortality rate was 4.51% and 2.15% in the motorized and non-motorized groups, respectively. After controlling for demographic factors and injury severity, the incidence rate ratio of mortality did not differ significantly between motorized and non-motorized trauma groups (IRR 0.91, p=0.35). CONCLUSIONS: Non-motorized vehicular trauma remains a significant proportion of morbidity and mortality resulting from road traffic injuries. The injury severity and incidence rate ratio of mortality did not differ between motorized and non-motorized trauma groups. Health care providers should not underestimate the severity of injuries from non-motorized trauma.

RESUMEN

PRECIS: In African American patients with glaucoma, iStent/phacoemulsification lowered intraocular pressure and reduced glaucoma medication usage for up to 1 year, even in patients with prior selective laser trabeculoplasty (SLT). PURPOSE: Currently, no studies have examined the outcomes of a trabecular microbypass stent and phacoemulsification in African American patients. Here, the authors investigate whether iStent/phacoemulsification decreases intraocular pressure (IOP) and/or medication usage in African American patients with glaucoma. They are also interested in whether prior SLT would affect outcomes of iStent/phacoemulsification. PATIENTS AND METHODS: A multicenter, retrospective case series of eyes that underwent iStent/phacoemulsification between 2013 and 2017 with up to 1-year follow-up. Eyes with a confirmed diagnosis of glaucoma in African American patients were included. Eyes with neovascular glaucoma or closed angle glaucoma and eyes that underwent previous incisional glaucoma surgery were excluded. RESULTS: Eighty-nine eyes were included in the study and data for 66 eyes were available at postoperative year 1 (POY1). IOP decreased from 18.3±5.7 mm Hg to 15.9±4.6 (P<0.001) and glaucoma medication usage decreased from 1.9±1.1 to 1.1±1.1 (P<0.001) at POY1. Eyes that underwent prior SLT experienced less of a decrease in IOP when compared with eyes without prior SLT, but IOP at POY1 was not significantly different between these groups. Both groups had a similar reduction in medication usage. The most common complications were IOP spikes on postoperative day 1 and microhyphemas. CONCLUSIONS: In this cohort, there was a significant decrease in IOP and medication usage 1 year after iStent/phacoemulsification. iStent/phacoemulsification is an effective and safe treatment option in African American patients with glaucoma.

RESUMEN

OBJECTIVES: To examine guideline concordance across a national sample and determine the relationship between socioeconomic factors, use of recommended postoperative adjuvant therapy, and outcomes for patients with resected pN1 or pN2 non-small cell lung cancer. METHODS: All margin-negative pT1-3 N1-2 M0 non-small cell lung cancers treated with lobectomy or pneumonectomy without induction therapy in the National Cancer Database between 2006 and 2013 were included. Use of guideline-concordant adjuvant treatment, defined as chemotherapy for pN1 disease and chemotherapy with or without radiation for pN2 disease, was examined. Multivariable regression models were developed to determine associations of clinical factors with guideline adherence. Survival was estimated using Kaplan-Meier and Cox proportional hazard analyses. RESULTS: Of 13,462 patients, 10,113 had pN1 disease and 3349 had pN2 disease. Guideline-concordant adjuvant therapy was used in 6844 (67.7%) patients with pN1 disease and 2622 (78.3%) patients with pN2 disease. After multivariable adjustment, insurance status, older age, pneumonectomy, readmission, and longer postoperative stays were associated with lower likelihood of guideline concordance. Conversely, increased education level, later year of diagnosis, and greater nodal stage were associated with greater concordance. Overall, patients treated with guideline-concordant therapy had superior survival (5-year survival: 51.6 vs 36.0%; hazard ratio, 0.66; 95% confidence interval, 0.62-0.70, P < .001). CONCLUSIONS: Socioeconomic factors, including insurance status and geographic region, are associated with disparities in use of adjuvant therapy as recommended by National Comprehensive Cancer Network guidelines. These disparities significantly impact patient survival. Future work should focus on improving access to appropriate adjuvant therapies among the under insured and socioeconomically disadvantaged.

RESUMEN

PURPOSE: Many surgeons remove the ripcord in the Baerveldt glaucoma drainage device to better control tube opening and intraocular pressure (IOP) lowering postoperatively. However, complications following Baerveldt implant surgery with or without ripcord removal are not well-characterized. We performed a prospective, randomized trial to test the hypothesis that scheduled ripcord removal decreases complications and final IOP. METHODS: Eighty-one patients were enrolled and randomized to scheduled ripcord removal at postoperative week 3 or to observation. They were followed for 6 months, and outcomes were compared between the 2 groups. RESULTS: Forty-four patients were randomized to scheduled ripcord removal and 37 to observation. The intervention group had a similar rate of total complications after ripcord removal (36% vs. 24%, P=0.24), a lower rate of tube fibrin obstruction (2.3% vs. 13.5%, P=0.05), and a larger decrease in the number of medications (1.3 vs. 0.49 fewer medications, P=0.01). The removal group's mean IOP decrease was 8.6 mm Hg and success rate was 59%, defined as 5 mm Hg

RESUMEN

Nutrition education is significantly lacking from healthcare provider educational curricula despite its proven benefit for some of the most chronic and challenging diseases facing Americans today. We successfully developed and implemented an interprofessional, experiential nutrition education course for healthcare professional students that emphasizes evidence-based nutrition interventions for patient care.

RESUMEN

PURPOSE: The purpose of this study was to compare early postoperative outcomes of patients who underwent Baerveldt 350-mm aqueous drainage device (Abbott Medical Optics Inc., Santa Ana, CA) implantation with and without 7-0 polyglactin (vicryl) suture placement through tube fenestration to serve as a stenting wick. METHODS: Patients were identified by a retrospective review of the electronic medical records of one attending surgeon's Baerveldt implantation (LWH) conducted by searching the Current Procedural Terminology code "placement of aqueous shunt." All patients had tube ligature with 7-0 vicryl suture and 6-0 prolene placed as a ripcord with 4 fenestrations. Thirty-seven patients had no vicryl wick while 38 patients had a stenting wick. Data were collected from the preoperative visit, postoperative day 1, postoperative week 3, postoperative week 5, and postoperative month 2. RESULTS: Although intraocular pressure (IOP) and number of medications were reduced at every follow-up visit, there was no significant difference in IOP, percent reduction of IOP, number of medications, and visual acuity between patients with and without vicryl wick at each time point. Both groups also had comparable morbidity with no significant difference in ripcord removal, incidence of complications, or need for additional surgery. CONCLUSIONS: Baerveldt implantation with vicryl wick placement can safely lower IOP and medication burden but does not seem to offer additional utility to fenestration without vicryl wick.

RESUMEN

BACKGROUND: The postpartum period represents a critical window where many maternal and child deaths occur. We assess the quality of postpartum care (PPC) as well as efforts to improve service delivery through additional training and supervision in Health Centers (HCs) in Morogoro Region, Tanzania. METHODS: Program implementers purposively selected nine program HCs for assessment with another nine HCs in the region remaining as comparison sites in a non-randomized program evaluation. PPC quality was assessed by examining structural inputs; provider and client profiles; processes (PNC counselling) and outcomes (patient knowledge) through direct observations of equipment, supplies and infrastructure (n = 18) and PPC counselling (n = 45); client exit interviews (n = 41); a provider survey (n = 62); and in-depth provider interviews (n = 10). RESULTS: While physical infrastructure, equipment and supplies were comparable across study sites (with water and electricity limitations), program areas had better availability of drugs and commodities. Overall, provider availability was also similar across study sites, with 63% of HCs following staffing norms, 17% of Reproductive and Child Health (RCH) providers absent and 14% of those providing PPC being unqualified to do so. In the program area, a median of 4 of 10 RCH providers received training. Despite training and supervisory inputs to program area HCs, provider and client knowledge of PPC was low and the content of PPC counseling provided limited to 3 of 80 PPC messages in over half the consultations observed. Among women attending PPC, 29 (71%) had delivered in a health facility and sought care a median of 13 days after delivery. Barriers to PPC care seeking included perceptions that PPC was of limited benefit to women and was primarily about child health, geographic distance, gaps in the continuity of care, and harsh facility treatment. CONCLUSIONS: Program training and supervision activities had a modest effect on the quality of PPC. To achieve broader transformation in PPC quality, client perceptions about the value of PPC need to be changed; the content of recommended PPC messages reviewed along with the location for PPC services; gaps in the availability of human resources addressed; and increased provider-client contact encouraged.
