RESUMO

OBJECTIVE: Measure effect of late-afternoon communication and patient planning (CAPP) rounds to increase early electronic discharge orders (EDO). METHODS: We enrolled 4485 patients discharged from six subspecialty medical services. We implemented late-afternoon CAPP rounds to identify patients who could have morning discharge the subsequent day. After an initial successful implementation of the intervention, we identified lack of sustainability. We made changes with sustained implementation of the intervention. This is a before-after study of a quality improvement intervention. PROGRAM EVALUATION: Primary measures of intervention effectiveness were percentage of patients who received EDO by 11 am and patients discharged by noon. Additional measure of effectiveness were percent of patients admitted to the correct ward, emergency department (ED)-to-ward transfer time compared between intervention and nonintervention periods. We compared the overall expected LOS and the average weekly discharges to assess for comparability across the control and intervention time periods. We used the readmission rate as balancing measure to ensure that the intervention was not have unintended negative patients consequences. RESULTS: Expected length of stay based upon discharge diagnosis/comorbidities and readmission rates were similar across the intervention and control time periods. The average weekly discharges were not statistically significant. Percentage of EDO by 11 am was higher in the first intervention period, second intervention period and combined intervention periods (28.9% vs. 21.8%, P < 0.001) compared with the respective control periods. Percent discharged before noon increased in the first intervention period, second intervention period and for the combined intervention periods (17 vs. 11.8%, P < 0.001). There was no difference in the percent admitted to the correct ward and ED-to-ward transfer time. CONCLUSION: Afternoon CAPP rounds to identify early patient discharges the following day led to increase in EDO entered by 11 am and discharges by noon without an adverse change in readmission rates and LOS.

RESUMO

BACKGROUND: Low health literacy is associated with worse glycemic control among patients with diabetes; the relationship between health literacy and blood glucose among patients without diagnosed diabetes, particularly in resource-limited settings, is not known. Because emergency department patients are at risk for both low health literacy and undiagnosed diabetes, we examined their relationships among emergency department patients at the Georgetown Public Hospital Corporation in Guyana. METHODS: We conducted a cross-sectional study across random time blocks from May to August 2012 among Guyanese emergency department patients without a diagnosis of diabetes. Health literacy was assessed by the Single Item Literacy Screener (SILS, range 1-5); low health literacy was defined as SILS ≥ 3. We examined the relationships among health literacy, random blood glucose (RBG), and point-of-care glycated hemoglobin (HbA1c). RESULTS: Of the 228 enrolled patients, 125 (54%) were female, median age was 43 years (interquartile range 38 to 53), mean body mass index (BMI) was 25.6 kg/m(2) (standard deviation 6.8 kg/m(2)), and 103 (45.2%) had low health literacy. The receiver operating characteristic area under the curve for RBG to detect elevated HbA1c (≥48mmol/mol) was 0.94 (95% CI: 0.91-0.97). After adjustment for age, sex, BMI, ethnicity, and education, the odds of having HbA1c ≥ 48 mmol/mol, consistent with undiagnosed diabetes, rose with decreasing health literacy (OR 2.2, 95% CI 1.2-3.8, p = 0.007, per point decrease in literacy). CONCLUSION: This pilot study of Guyanese emergency department patients without diagnosed diabetes found that low health literacy was common and was associated with higher HbA1c and random blood glucose.

RESUMO

OBJECTIVE: The characteristics of staphylococcal skin and soft tissue infections (SSTIs) are poorly understood in northern South America and the Caribbean. The objectives of this study were to determine the frequency of methicillin resistance among Staphylococcus aureus isolates in an emergency department (ED) in Guyana and to identify specific molecular characteristics of these methicillin-resistant Staphylococcus aureus (MRSA) strains. METHODS: This was a cross-sectional study conducted at the main teaching hospital in Georgetown, Guyana. Eligible subjects included patients of all ages with SSTIs with obtainable purulent material. Purulent material was cultured, and S. aureus isolates were evaluated for antibiotic susceptibilities by disc diffusion. Molecular characterisation of MRSA isolates included identification of SCCmec type, assignment of genetic relatedness by rep-PCR and determination of the presence of two exotoxins, Panton-Valentine Leukocidin (PVL) and LukAB. RESULTS: Eighty-five samples were collected; of these, 47 grew S. aureus. 24 of the 47 S. aureus samples were MRSA (51%; 95% CI 37% to 65%), representing 28% of all samples. All MRSA isolates were SCCmec type IV, PVL positive, LukAB positive and were highly related to the current epidemic clone in the USA, USA300. CONCLUSIONS: Here, we demonstrate a clinically significant proportion of methicillin resistance in SSTI-associated staphylococcal isolates. Guyanese isolates were highly related to the most common community-associated strain seen in the USA, USA300. These results have important implications for empiric antibiotic therapy and infection control policies in Guyana and similar settings.

RESUMO

BACKGROUND: Intimate partner violence (IPV) is prevalent throughout the world and is a devastating public health problem. Healthcare workers (HCWs) are tasked with treating victims of IPV but may be victims themselves. Guyana is a lower-middle income country in South America. This study sought to determine the knowledge and attitudes of Guyanese HCWs and their perceived barriers to providing care in addition to determining the prevalence of IPV victimization and perpetration among HCWs. METHODS: HCWs at the only tertiary care hospital in the Guyana completed an anonymous survey that comprised 30 questions relating to IPV. RESULTS: The survey was completed by 87.5% of eligible HCWs. Of the respondents, 81.8% were female, 49.9% had ever experienced abuse and 21% admitted to perpetrating violence. Multivariate analysis found that the age groups 31-40 years (OR 2.3, 95% CI 1.1-4.6) and 41-50 years (OR 2.3, 95% CI 1.2-4.7) had higher odds of accepting justification for physical violence, and so did nursing staff (OR 4.3, 95% CI 1.4-13.1). Overall, 29.9% of HCWs accepted justification for physical violence in at least one of the named scenarios. CONCLUSION: This study demonstrates a high prevalence of IPV among HCWs and identifies prevailing attitudes regarding IPV. This knowledge is essential in developing effective, appropriate training programs and identifies a need to address IPV among the healthcare workforce.

RESUMO

INTRODUCTION: Academic departments of emergency medicine are becoming increasingly involved in assisting with the development of long-term emergency medicine training programs in low and middle-income countries. This article presents our 10-year experience working with local partners to improve emergency medical care education in Guyana. METHODS: The Vanderbilt Department of Emergency Medicine has collaborated with the Georgetown Public Hospital Corporation on the development of Emergency Medicine skills followed by the implementation of an emergency medicine residency training program. Residency development included a needs assessment, proposed curriculum, internal and external partnerships, University of Guyana and Ministry of Health approval, and funding. RESULTS: In our experience, we have found that our successful program initiation was due in large part to the pre-existing interest of several local partners and followed by long-term involvement within the country. As a newer specialty without significant local expertise, resident educational needs mandated a locally present full time EM trained attending to serve as the program director. Both external and internal funding was required to achieve this goal. Local educational efforts were best supplemented by robust distance learning. The program was developed to conform to local academic standards and to train the residents to the level of consultant physicians. Despite the best preparations, future challenges remain. CONCLUSION: While every program has unique challenges, it is likely many of the issues we have faced are generalizable to other settings and will be useful to other programs considering or currently conducting this type of collaborative project.

RESUMO

BACKGROUND: Left without being seen (LWBS) proportions are commonly used as quality control indicators, but little data is available on LWBS proportions in the developing world. This study sought to determine the proportion and characteristics of patients who LWBS from the emergency department (ED) of the main public hospital in Georgetown, Guyana. METHODS: This is a retrospective cross-sectional analysis of an ED quality assurance database. Registration personnel collected demographic information on patients presenting to the ED over a 2-week period in July 2010. Both univariate and multivariate analysis were conducted to determine patient characteristics associated with LWBS. RESULTS: The LWBS proportion was 5.7%. In univariate analysis, patients 18 or older (OR 1.48, 95%CI 1.03-2.12), presenting during the 4PM-12AM shift (OR 2.15, 95%CI 1.53-3.01), with non-urgent triage classification (OR 1.88, 95%CI 1.76-4.66), with non-traumatic chief complaints (OR 1.70, 95%CI 1.14-2.55), or who were not transferred (OR 2.13, 95%CI 1.00-4.55) had significantly higher odds of LWBS. On multivariate analysis, only patients 18 or older (OR 1.54, 95%CI 1.02-2.33), presenting during the 4PM-12AM shift (OR 2.29, 95%CI 1.54-3.40), and with non-traumatic chief complaints (OR 2.39, 95%CI 1.43-4.02) were found to be significantly associated with LWBS. Sex, residence in the capital city, time to triage, transfer status, use of EMS, and triage classification were not statistically associated with LWBS. CONCLUSIONS: LWBS proportions are used as quality control indicators and this study determined the LWBS proportion at a public hospital in a developing country and some of the patient characteristics associated with LWBS. This can be helpful to develop strategies to decrease LWBS proportions and to assess progress over time.

RESUMO

BACKGROUND: Intimate partner violence (IPV) occurs throughout the world, and has both short- term and long- term negative health effects. Little is know about the prevalence of IPV in patients presenting to Emergency Departments (EDs) in the developing world. This information is needed to help delineate the scope of the problem and shape effective interventions to combat IPV. The purpose of this study was to determine the prevalence of intimate partner violence in adult patients with acute traumatic injuries presenting to an ED in Georgetown, Guyana. METHODS: Retrospective descriptive analysis of a prospectively collected ED quality assurance database. Patients 18 years or older who presented with a traumatic injury and answered the question "Was the injury inflicted by a domestic partner?" were included in the analysis. RESULTS: Overall, 38 of 475 (8%) patients admitted to having injuries inflicted by a domestic partner. Thirty- one (81.6%) patients disclosing IPV were female and 7 (18.4%) were male. The self- reported prevalence of IPV in females presenting with traumatic injuries was 16% compared to 2% for males (RR 6.4; 95% CI 2.9-14.3). IPV was the cause of 31 of the 67 (46.3%) women presenting with assaults. CONCLUSIONS: IPV is thought to be a serious problem in Guyana, and this study confirms a high prevalence (16%) of IPV in women presenting with traumatic injuries to the Georgetown Public Hospital Corporation ED. This is likely a significant underestimate of the true prevalence.

RESUMO

BACKGROUND: The proportion of patients with advanced chronic kidney disease (CKD) initiating dialysis therapy at a higher glomerular filtration rate (GFR) has increased during the past decade. Recent data suggest that higher GFR may be associated with increased mortality. STUDY DESIGN: A meta-analysis of cohort studies and trials. SETTING & POPULATION: Patients with advanced CKD. SELECTION CRITERIA FOR STUDIES: We performed a systematic literature search in MEDLINE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, American Society of Nephrology abstracts, and bibliographies of retrieved articles to identify studies reporting on GFR at dialysis therapy initiation and mortality. PREDICTOR: Estimated or calculated GFR at dialysis therapy initiation. OUTCOME: Pooled adjusted hazard ratio (HR) of continuous GFR for all-cause mortality. RESULTS: 16 cohort studies and 1 randomized controlled trial were identified (n = 1,081,116). By meta-analysis restricted to 15 cohorts (n = 1,079,917), higher GFR at dialysis therapy initiation was associated with a higher pooled adjusted HR for all-cause mortality (1.04; 95% CI, 1.03-1.05; P < 0.001). However, there was significant heterogeneity (I(2) = 97%; P < 0.001). The association persisted among the 9 cohorts that adjusted analytically for nutritional covariates (HR, 1.03; 95% CI, 1.02-1.04; P < 0.001; residual I(2) = 97%). The highest mortality risk was observed in hemodialysis cohorts (HR, 1.05; 95% CI, 1.02-1.08; P < 0.001), whereas there was no association between GFR and mortality in peritoneal dialysis cohorts (HR, 1.04; 95% CI, 0.99-1.08, P = 0.1; residual I(2) = 98%). Finally, higher GFR was associated with a lower mortality risk in cohorts that calculated GFR (HR, 0.80; 95% CI, 0.71-0.91; P = 0.003), contrasting with a higher mortality risk in cohorts that estimated GFR (HR, 1.04; 95% CI, 1.03-1.05; P < 0.001; residual I(2) = 97%). LIMITATIONS: Paucity of randomized controlled trials, different methods for determining GFR, and substantial heterogeneity. CONCLUSIONS: Higher estimated rather than calculated GFR at dialysis therapy initiation is associated with a higher mortality risk in patients with advanced CKD, independent of nutritional status. Although there was substantial heterogeneity of effect size estimates across studies, this observation requires further study.

RESUMO

In 2007, the WHO recommended that healthcare providers in areas of a generalised HIV epidemic perform HIV testing on all adults and adolescents presenting for healthcare. Studies regarding patient acceptability of opt-out testing, however, have reported wide variation in acceptance rates. This study examines patient-reported acceptability of such testing at the emergency department (ED) of Georgetown Public Hospital Corporation, the largest public hospital in Guyana. In June 2010, a convenience sample of 343 non-critical adult patients who presented to the ED were interviewed regarding potential acceptance of opt-out HIV testing, with 75.5% (95% CI 70.5-80.0%) stating they would accept testing should it be implemented in the ED. Of 12 patient characteristics, 3 had significant differences in acceptance rates on multivariate analysis: age; gender; and previous HIV testing. In this study, potential reasons for declining testing were also examined. The highest percentage of patient agreement was with the statements 'I have had an HIV test recently enough' (84%, 95% CI 74.0-91.4%) and 'I am not at risk for HIV/AIDS' (83%, 95% CI 73.0-90.4%). The results of this study indicate that the majority of patients in this setting would accept opt-out HIV testing, although some still had concerns regarding testing. Opt-out testing in the ED has the potential to facilitate national goals for increased testing and diagnosis.

RESUMO

Nonadherence in kidney transplant recipients was evaluated in this report using a questionnaire with five binary questions and one question on a continuous scale. Study participants at the University of Utah Transplant Program (n = 199) were 43.0 ± 14.2 years old; 67% were males, and 81% were White. Two questions that produced heterogeneous outcome were analyzed: 'Do you ever forget to take your medication?' (79% no, 21% yes) and 'Have you ever taken your medications late?' (67% no, 33% yes). Responses to these questions correlated (χ² 65.2, p < 0.001; correlation coefficient 0.57, p < 0.001). We performed a logistic regression analysis to identify factors associated with the combined outcome of forgetting/not taking medications altogether or taking medications off schedule. Higher comorbidity index [odds ratio (OR) 2.19, p < 0.001], living (compared to deceased) donor (OR 2.81, p = 0.005) and full-time employment were associated with forgetting medications or taking them late (OR 3.12, p = 0.01). Recipient age tended to be associated with lower risk of nonadherence, but did not reach statistical significance (OR 0.98 per year of age, p = 0.13). Education level, smoking status, recipient race, dialysis modality, number of medications and the time since first kidney transplantation were not associated with the outcome. In conclusion, renal transplant recipients with greater comorbidity, receiving kidney from a living donor and with full-time employment reported lower levels of medication adherence.

RESUMO

BACKGROUND AND OBJECTIVES: The optimal time of dialysis initiation is unclear. The goal of this analysis was to compare survival outcomes in patients with early and late start dialysis as measured by kidney function at dialysis initiation. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We performed a retrospective analysis of patients entering the U.S. Renal Data System database from January 1, 1995 to September 30, 2006. Patients were classified into groups by estimated GFR (eGFR) at dialysis initiation. RESULTS: In this total incident population (n = 896,546), 99,231 patients had an early dialysis start (eGFR >15 ml/min per 1.73 m(2)) and 113,510 had a late start (eGFR ≤5 ml/min per 1.73 m(2)). The following variables were significantly (P < 0.001) associated with an early start: white race, male gender, greater comorbidity index, presence of diabetes, and peritoneal dialysis. Compared with the reference group with an eGFR of >5 to 10 ml/min per 1.73 m(2) at dialysis start, a Cox model adjusted for potential confounding variables showed an incremental increase in mortality associated with earlier dialysis start. The group with the earliest start had increased risk of mortality, wheras late start was associated with reduced risk of mortality. Subgroup analyses showed similar results. The limitations of the study are retrospective study design, potential unaccounted confounding, and potential selection and lead-time biases. CONCLUSIONS: Late initiation of dialysis is associated with a reduced risk of mortality, arguing against aggressive early dialysis initiation based primarily on eGFR alone.

RESUMO

BACKGROUND: Pertussis is increasing among adolescents and adults despite universal childhood vaccination. This investigation describes an outbreak of pertussis among undergraduate students and assesses the burden of cough illness on a college campus. METHODS: Students presenting with prolonged cough were evaluated with culture, polymerase chain reaction (PCR), and serology. An e-mail survey was performed to determine the burden of cough illness on campus. RESULTS: Thirty-seven undergraduates were evaluated. Their mean duration of cough was 28 days. No student had cultures positive for B. pertussis; one was PCR positive. Ten (27%) had serologic values consistent with acute pertussis infection. The e-mail survey was returned by 225/500 (45%) students. Of these, 66 (29%; 95% confidence interval [CI], 23%-36%) reported a cough of 2 weeks or longer duration during the fall semester. A conservative estimate showed that the campus-wide incidence of a cough illness meeting the Centers for Disease Control and Prevention case definition for pertussis was 13% (95% CI, 10%-16%) during the fall semester. CONCLUSIONS: Adolescents and young adults are susceptible to pertussis infection. This study demonstrates that there was a substantial rate of pertussis infection during an outbreak on a college campus. Our findings support the routine use of the acellular pertussis vaccine in adolescents and adults.

RESUMO

For both different individuals and modes of locomotion, the external forces determining all-out sprinting performances fall predictably with effort duration from the burst maximums attained for 3 s to those that can be supported aerobically as trial durations extend to roughly 300 s. The common time course of this relationship suggests a metabolic basis for the decrements in the force applied to the environment. However, the mechanical and neuromuscular responses to impaired force production (i.e., muscle fatigue) are generally considered in relation to fractions of the maximum force available, or the maximum voluntary contraction (MVC). We hypothesized that these duration-dependent decrements in external force application result from a reliance on anaerobic metabolism for force production rather than the absolute force produced. We tested this idea by examining neuromuscular activity during two modes of sprint cycling with similar external force requirements but differing aerobic and anaerobic contributions to force production: one- and two-legged cycling. In agreement with previous studies, we found greater peak per leg aerobic metabolic rates [59% (+/-6 SD)] and pedal forces at VO2 peak [30% (+/-9)] during one- vs. two-legged cycling. We also determined downstroke pedal forces and neuromuscular activity by surface electromyography during 15 to 19 all-out constant load sprints lasting from 12 to 400 s for both modes of cycling. In support of our hypothesis, we found that the greater reliance on anaerobic metabolism for force production induced compensatory muscle recruitment at lower pedal forces during two- vs. one-legged sprint cycling. We conclude that impaired muscle force production and compensatory neuromuscular activity during sprinting are triggered by a reliance on anaerobic metabolism for force production.

RESUMO

OBJECTIVE: The objective of this study was to assess attitudes of patrons and medical school faculty about physicians with nontraditional facial piercings. We also examined whether a piercing affected the perceived competency and trustworthiness of physicians. DESIGN: Survey. SETTING: Teaching hospital in the southeastern United States. PARTICIPANTS: Emergency department patrons and medical school faculty physicians. INTERVENTIONS: First, patrons were shown photographs of models with a nontraditional piercing and asked about the appropriateness for a physician or medical student. In the second phase, patrons blinded to the purpose of the study were shown identical photographs of physician models with or without piercings and asked about competency and trustworthiness. The third phase was an assessment of attitudes of faculty regarding piercings. MEASUREMENTS AND MAIN RESULTS: Nose and lip piercings were felt to be appropriate for a physician by 24% and 22% of patrons, respectively. Perceived competency and trustworthiness of models with these types of piercings were also negatively affected. An earring in a male was felt to be appropriate by 35% of patrons, but an earring on male models did not negatively affect perceived competency or trustworthiness. Nose and eyebrow piercings were felt to be appropriate by only 7% and 5% of faculty physicians and working with a physician or student with a nose or eyebrow piercing would bother 58% and 59% of faculty, respectively. An ear piercing in a male was felt to be appropriate by 20% of faculty, and 25% stated it would bother them to work with a male physician or student with an ear piercing. CONCLUSIONS: Many patrons and physicians feel that some types of nontraditional piercings are inappropriate attire for physicians, and some piercings negatively affect perceived competency and trustworthiness. Health care providers should understand that attire may affect a patient's opinion about their abilities and possibly erode confidence in them as a clinician.

RESUMO

There has been increasing awareness concerning the problem of acute pain in ED patients. There has, however, been little attention devoted to chronic pain in ED patients. Our purpose was to determine the extent and severity of chronic pain in adult ED patients. Adult noncritical patients were interviewed to determine if they had chronic pain. The Chronic Pain Grade scale was used to grade the severity of the pain. Four hundred seventy-six patients were enrolled. One hundred ninety-three (40.6%) had chronic pain. Sixty-five (13.7%) identified their chronic pain as the reason for the ED visit. The spine and abdomen were the most common sites of chronic pain. Those with chronic pain were more likely to be unemployed (relative risk [RR], 1.77; 95% confidence interval [CI], 1.34-2.34), disabled (RR, 3.24; 95% CI, 1.95-5.40), and have had four or more ED visits in the past year (RR, 2.47; 95% CI, 1.76-3.47). A total of 32.1% had class 3 pain (high disability, moderately limiting) and 58.0% had class 4 pain (high disability, severely limiting). Many noncritical ED patients have chronic pain. They are high users of ED services and most have not been seen in a pain clinic. Further studies are indicated to further delineate the demographics of this population and determine which patients would best be served in other healthcare settings. In an effort to improve care, ED physicians should be educated in diagnosing and treating chronic pain.

RESUMO

OBJECTIVES: Identifying the etiologies of adverse outcomes is an important first step in improving patient safety and reducing malpractice risks. However, relatively little is known about the causes of emergency department-related adverse outcomes. The objective was to describe a method for identification of common causes of adverse outcomes in an emergency department. This methodology potentially can suggest ways to improve care and might provide a model for identification of factors associated with adverse outcomes. METHODS: This was a retrospective analysis of 74 consecutive files opened by a malpractice insurer between 1995 and 2000. Each risk-management file was analyzed to identify potential causes of adverse outcomes. The main outcomes were rater-assigned codes for alleged problems with care (e.g., failures of communication or problems related to diagnosis). RESULTS: About 50% of cases were related to injuries or abdominal complaints. A contributing cause was found in 92% of cases, and most had more than one contributing cause. The most frequent contributing categories included failure to diagnose (45%), supervision problems (31%), communication problems (30%), patient behavior (24%), administrative problems (20%), and documentation (20%). Specific relating factors within these categories, such as lack of timely resident supervision and failure to follow policies and procedures, were identified. CONCLUSIONS: This project documented that an aggregate analysis of risk-management files has the potential to identify shared causes related to real or perceived adverse outcomes. Several potentially correctable systems problems were identified using this methodology. These simple, descriptive management tools may be useful in identifying issues for problem solving and can be easily learned by physicians and managers.

RESUMO

OBJECTIVE: Neonates with fever generally undergo a full, invasive septic evaluation to exclude serious bacterial infection (SBI). The risk of SBI in febrile older infants and children with documented respiratory syncytial virus (RSV) infection has been found to be negligible. The purpose of this study was to investigate the prevalence of SBI in febrile infants who were younger than 8 weeks and had documented RSV infection and to compare the risk of SBI with control subjects who were febrile and RSV-negative. METHODS: This was a retrospective cohort study of infants who were age 8 weeks or less and presented with documented fever to the emergency department at an urban children's hospital in October through April during a 4-year period. RSV-positive cases were gender- and age-matched to febrile RSV-negative control subjects. Clinical characteristics and the rate of SBI were compared between the 2 groups. RESULTS: A total of 174 previously healthy infants with fever and a positive RSV antigen test were identified and matched with 174 previously healthy infants with fever and a negative RSV test. Infants with RSV infection were more likely to present with upper respiratory infection symptoms, increased work of breathing, and apnea. Overall, 2 patients in the RSV group had SBI (both with urinary tract infections), compared with 22 in the control group (relative risk: 0.009), 17 of which were urinary tract infections. CONCLUSIONS: The risk of SBI in febrile infants with RSV infection seems to be very low, particularly in comparison with a control group of RSV-negative infants. These data suggest that full septic evaluations are not necessary in nontoxic-appearing infants with a positive RSV test. It seems to be prudent to examine the urine in these infants, as there is a clinically relevant rate of urinary tract infection.
