Health literacy and blood glucose among Guyanese emergency department patients without diagnosed diabetes: a cross-sectional study.

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.

Prevalence and molecular characteristics of methicillin-resistant Staphylococcus aureus among skin and soft tissue infections in an emergency department in Guyana.

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.

Personal experiences and attitudes towards intimate partner violence in healthcare providers in Guyana.

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.

Emergency Medicine in Guyana: Lessons from Developing the Country's First Degree-conferring Residency Program.

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.

Who leaves the emergency department without being seen? A public hospital experience in Georgetown, Guyana.

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.

Prevalence of intimate partner violence in patients presenting with traumatic injuries to a Guyanese emergency department.

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.

Patient perspectives on opt-out HIV screening in a Guyanese emergency department.

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.

Outbreak of pertussis on a college campus.

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.

Should physicians have facial piercings?

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.

Chronic pain in the ED.

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.

Cause-and-effect analysis of risk management files to assess patient care in the emergency department.

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.

Prevalence of serious bacterial infections in febrile infants with respiratory syncytial virus infection.

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.
