ABSTRACT
BACKGROUND: Nurses are essential members of the healthcare workforce and were among the first-line carers for patients in community and hospital settings during the COVID-19 pandemic. As a result, they were at a heightened risk of infection, resulting in several reported deaths among nursing staff. Several preventive measures were adopted to contain the spread of the COVID-19 virus. This study aims to explore the knowledge, attitudes, and practices (KAP) of nurses regarding hand hygiene, mask wearing, and social distancing measures in healthcare settings in Barbados during the COVID-19 pandemic. METHOD: An online survey of nurses working in public hospitals and polyclinics (public primary care clinics) in Barbados from March 2021 to December 2021 was conducted. A nonsystematic convenience sampling method was employed to recruit nurses who were readily available and willing to participate. A questionnaire captured the sociodemographic information and knowledge and practices related to hand hygiene, the use of face masks, and social distancing. Each correct response received one mark. Overall knowledge scores were categorized as poor (<60%), average (60-80%), or good (>80-100%). RESULTS: Of the 192 participants, the majority were female (82.8%) and had >5 years of experience (82%). The findings revealed that 45.8% had poor knowledge of hand hygiene, and that the knowledge of 43.8% of respondents was average. Multivariable logistic regression showed that, after adjustment for age and gender, registered nurses had 2.1 times increased odds (95% confidence interval 1.0, 4.2) of having good knowledge compared to other nursing categories. Regarding mask wearing, 53.6% of nurses had average knowledge, and 27.1% had good knowledge. Multivariable logistic regression showed that, after adjustment for age and gender, registered nurses had 3.3 times increased odds (95% confidence interval 1.5, 7.4) of having good knowledge compared to nursing assistants. A total of 68.6% of respondents followed the correct steps of handwashing every time, and 98.3% wore a mask in public places. More than half of the nurses (51.2%) kept a safe distance from others to avoid spreading SARS-CoV-2; one-third were in a crowded place(s) in the past three months, and 55.8% usually followed guidelines for social isolation as recommended by the WHO. CONCLUSIONS: The study identified knowledge deficiencies related to hand hygiene and wearing masks among nurses. It is imperative to provide additional training on infection control measures.
ABSTRACT
Background: Globally, 1.3 billion people were considered food insecure as of 2022. In the Caribbean region, the prevalence of moderate or severe food insecurity was 71.3% as of 2020, the highest of all subregions in Latin America. Experienced based measurement scales, like the Latin American and Caribbean Food Security Scale, are efficient measurement tools of food insecurity used globally. The Eastern Caribbean Health Outcomes Research Network (ECHORN) Cohort Study is a population-based longitudinal cohort study in the two Caribbean U.S. territories of Puerto Rico and the U.S. Virgin Islands, as well as in Barbados and Trinidad & Tobago. The purpose of this research was to examine the demographic, psychosocial, behavioral, and environmental risk factors associated with household food insecurity (HFI) among adults ≥40 years of age in the ECHORN cohort. Methods: A cross-sectional analysis of baseline ECHORN cohort study data was conducted. The primary outcome was household food insecurity (none, mild, moderate/severe). A total of 16 known and potential risk factors were examined for their association with HFI. The ANOVA and chi-square statistics were used in bivariate analysis. Ordinal logistic regression was used for the multivariable and sex stratified analyses. Results: More than one-quarter of the sample (27.3%) experienced HFI. In bivariate analyses, all risk factors examined except for sex, were significantly associated with HFI status. In the multivariable analysis, all variables except sex, education, marital status, smoking status, and residing in Puerto Rico were significant predictors of HFI in the adjusted model. In sex stratified analysis, depression, food availability, self-rated physical health, and island site were significantly associated with increased odds of worsening HFI for women, but not for men. Source of potable water was an important risk factor for both men and women. Discussion: The prevalence of HFI in the ECHORN cohort study is comparable to other studies conducted in the region. While women did not have an increased risk of HFI compared to men, a different set of risk factors affected their vulnerability to HFI. More research is needed to understand how water and food security are interrelated in the ECHORN cohort.

Introduction: Learning style (LS) frameworks have been implemented by educators to promote participatory learning in order to strengthen learner engagement and to enhance learning outcomes. Self-efficacy has been shown to have an association with learning style and is a predictor of clinical performance and other qualities in medical students. This study examined the perspectives of second and final year medical students in a Caribbean-based medical school, relative to their learning approaches, teaching exposures and preparation for assessments. Methods: An interpretivist qualitative approach was used to analyze data from two focus groups, conducted as part of a sequential mixed-methods study (November 2018-February 2019) with medical students in the second and final year of study. Discussions were audio-recorded, transcribed verbatim, and inductively coded with in-depth thematic analysis assisted by NVivo software. Results: Six Year 2 (Female: Male = 5:1) and seven Year 5 (Female: Male = 5:2) participants, ranging between 18 and 34 years and with a range of LS were recruited into the study. Analysis and data reduction produced three organizing themes: "Dynamics of information delivery and acquisition", "Pivoting", and "LS identification, awareness and mutability", and the global construct "Individual and environmental factors modulate the influence of LS preference in triggering self-efficacy". In managing information received in class, students used textbooks, YouTube videos, and collaborative learning to augment perceived gaps in lectures and their personal notes. Learning style self-awareness is useful for facilitating self-efficacy throughout medical school, especially at points of transition within the programme of study. Conclusion: LS theory and testing appear to be useful for student and teacher awareness. In practice, honing students' adaptability to varying learning settings may be more relevant in helping students achieve self-efficacy.
ABSTRACT
The identification of nocturnal nondipping blood pressure (< 10% drop in mean systolic blood pressure from awake to sleep periods), as captured by ambulatory blood pressure monitoring, is a valuable element of risk prediction for cardiovascular disease, independent of daytime or clinic blood pressure measurements. However, capturing measurements, including determination of wake/sleep periods, is challenging. Accordingly, we sought to evaluate the impact of different definitions and algorithms for defining sleep onset on the classification of nocturnal nondipping. Using approaches based upon participant self-reports, applied definition of a common sleep period (12 am -6 am), manual actigraphy, and automated actigraphy we identified changes to the classification of nocturnal nondipping, and conducted a secondary analysis on the potential impact of an ambulatory blood pressure monitor on sleep. Among 61 participants in the Eastern Caribbean Health Outcomes Research Network hypertension study with complete ambulatory blood pressure monitor and sleep data, the concordance for nocturnal nondipping across methods was 0.54 by Fleiss' Kappa (depending on the method, 36 to 51 participants classified as having nocturnal nondipping). Sleep quality for participants with dipping versus nondipping was significantly different for total sleep length when wearing the ambulatory blood pressure monitor (shorter sleep duration) versus not (longer sleep duration), although there were no differences in sleep efficiency or disturbances. These findings indicate that consideration of sleep time measurements is critical for interpreting ambulatory blood pressure. As technology advances to detect blood pressure and sleep patterns, further investigation is needed to determine which method should be used for diagnosis, treatment, and future cardiovascular risk.
ABSTRACT
Purpose: The COVID-19 pandemic precipitated a swift transition to online learning in medical and health sciences. This study investigated the associations of previous experience with online learning, current confidence with online learning, and resilient coping skills with perceived stress reported by pharmacy students during the emergency transition to online learning. Methods: Undergraduate pharmacy students (N=113, response rate = 41%) completed an online, self-report, cross-sectional survey during April-June 2020. Measures included Likert items measuring prior experience and current comfort levels with online learning, the Brief Resilient Coping Scale (BRCS), and the Perceived Stress Scale 10-Item Version (PSS-10). Experience, comfort with online learning, reported scores, and internal consistency for the BRCS and PSS-10 were summarized. A linear regression model examined the associations of prior experience with online education, gender, and resilient coping with perceived stress. Results: Of the 113 respondents (78% female, mean age 22.3 years), > 50% had only occasional prior experience with online learning, coursework, and examinations, but 63% expressed confidence with online learning. Mean PSS-10 and BRCS scores were 23.8 and 13.3, respectively, and both scales demonstrated good internal consistency (α > 0.80). BRCS score was the single predictor of the PSS-10 score (r2 = 0.18, p < 0.001). Female gender was not a significant predictor (p = 0.11). A multiple regression model explained moderate variation in perceived stress (adjusted R2 = 0.19). Conclusion: PSS-10 and BRCS scores indicated moderate levels of stress and coping skills among students during online teaching. Most students had some prior exposure to online learning, coursework, and examinations. Higher resiliency scores, but not prior online learning experience, predicted lower perceived stress.
ABSTRACT
Noncommunicable diseases (NCDs) account for a higher proportion of mortality and morbidity in the Caribbean and US territories-majority-minority communities-than in the United States or Canada. Strategies to address this disparity include enhancing data collection efforts among racial/ethnic communities. The ECHORN Cohort Study (ECS), a regional adult cohort study, estimates prevalence and assesses risk factors for NCDs in two United States territories and two Caribbean islands. Here, we describe the cohort study approach, sampling methods, data components, and demographic makeup for wave one participants. We enrolled ECS participants from each participating island using random and probability sampling frames. Data components include a clinical examination, laboratory tests, a brief clinical questionnaire, and a self-administered health survey. A subset of ECS participants provided a blood sample to biobank for future studies. Approximately 2961 participants were enrolled in wave one of the ECS. On average, participants are 57 years of age, and the majority self-identify as female. Data from the ECS allow for comparisons of NCD outcomes among racial/ethnic populations in the US territories and the US and evaluations of the impact of COVID-19 on NCD management and will help highlight opportunities for new research.

Background: Peripheral arterial disease (PAD) is a risk factor for amputation and systemic atherosclerotic disease. Barbados has a high diabetes prevalence, and 89% of diabetes-related hospital admissions are for foot problems. Foot examination is infrequent in Barbados primary care. The prevalence and potential risk factors for PAD in people with diabetes in Barbados were studied. Methods: Multistage probability sampling was used to select a representative population sample of people ≥25 years of age with known diabetes or fasting blood glucose ≥7 mmol/L or HbA1c ≥6.5%. We administered the Edinburgh claudication questionnaire and assessed the ankle brachial pressure index (ABI) and Doppler waveform in both dorsalis pedis and posterior tibial arteries. Participants were classified into categories based on ABI as follows: PAD ≤0.90 in any leg; borderline 0.91 to 0.99 in one leg and the other not ≤0.90 or >0.4; normal 1.00 to 1.40 in both legs; and non-compressible >1.40 in one leg and the other not ≤0.9. Waveforms crossing the zero-flow baseline were categorised as normal. Multivariable logistic regression assessed the associations of potential risk factors with PAD. Results: Of 236 participants (74% response rate, 33% male, median age 58.6 years), 51% had previously diagnosed diabetes. Of nine people with symptoms of definite or atypical claudication, four had PAD and one had non-compressible arteries. ABI prevalence (95% CI) was PAD 18.6% (13.8, 24.6), borderline 21.9% (16.6, 28.4), normal 55.5% (49.4, 61.5) and non-compressible 3.9% (1.6, 9.3). Increasing age and female gender were independently associated with PAD. Over 80% of normal legs (ABI 1.00 to 1.40) had normal posterior tibial and dorsalis pedis waveforms, while only 23% legs with PAD (ABI ≤0.90) had normal waveforms in both arteries (Kappa = 0.43). Conclusion: Asymptomatic PAD is common in people with diabetes and requires ABI screening to detect it. Female gender is associated with PAD.

AIMS: Barbados implemented a 10% tax on sugar sweetened beverages (SSBs) in 2015. We aimed to determine knowledge, attitudes and practices towards SSB consumption and taxation among people with type 2 diabetes (T2D) attending public sector primary care clinics in Barbados. METHODS: People with T2D attending public sector clinics completed a survey including the Beverage Intake Questionnaire (BEVQ-15). Waist circumference was measured. RESULTS: Of 384 participants (34.6% male, median age 67 years, interquartile range 60-74 years, African descent 97.6%) 45.9% had diabetes diagnosed for >10 years, 30.7% used insulin, 31.8% had not seen a dietician since diabetes diagnosis, and 62.2% had abdominal obesity. Most (91.1%) thought that consuming SSB was unhealthy and 91% felt that reducing intake would be easy. Only 44.7% favoured the current 10% tax and 29.7% favoured a 20% tax. The median daily SSB consumption was 26.6ml (IQR 3.0-53.2). Responses did not differ by age, gender or abdominal obesity status (p>0.5). Weight loss was being attempted by 45.6% and 21.1% with and without abdominal obesity respectively (p<0.0001). CONCLUSIONS: While most felt SSB consumption is harmful and the median reported consumption contributes few calories to the diet, a minority supported the current tax.

INTRODUCTION: Low plasma renin activity hypertension is prevalent in Afro-Caribbean persons. Reduced angiotensin converting enzyme 2 activity from the counter angiotensin converting enzyme 2 /angiotensin-(1-7)/Mas receptor axis of the renin angiotensin aldosterone system has been reported in people with pre-hypertension, type 2 diabetes mellitus and chronic renal disease. This study investigates whether an imbalance in the regulatory mechanisms between the pressor arm of the renin angiotensin aldosterone system (angiotensin converting enzyme/angiotensin II/AT1 receptor) and the depressor axis (angiotensin converting enzyme 2/angiotensin-(1-7)/Mas receptor) predisposes persons of African descent to hypertension. METHODS: In total, 30 normotensives and 30 recently diagnosed hypertensives aged 18-55 of Afro-Caribbean origin who are naïve to antihypertensive treatment will be recruited from public sector polyclinics in Barbados. Demographic and anthropometric data, clinical blood pressure readings, 24-hour urine collections and venous blood samples will be collected. Biological samples will be analysed for renin angiotensin aldosterone system peptide markers using radioimmunoassay. CONCLUSION: We describe the design, methods and rationale for the characterization of renin angiotensin aldosterone system mechanisms that may contribute to hypertension predisposition in persons of African descent. Our findings will characterize any imbalance in the counter axes of the renin angiotensin aldosterone system in hypertensive Afro-Caribbeans with a potential view of identifying novel approaches with the use of renin angiotensin aldosterone system and mineralocorticoid blockers to manage the condition.

Objective: To describe the rationale and design of a prospective study of ambulatory blood pressure measurement (ABPM) combined with measurement of contextual factors to identify hypertensive phenotypes in a Caribbean population with high rates of HTN and cardiovascular disease. Design: Prospective, multi-center sub-study. Setting: Eastern Caribbean Health Outcomes Research Network Cohort (ECHORN) Study, with study sites in Puerto Rico, the US Virgin Islands, Trinidad and Tobago, and Barbados. Participants: Community-residing adults without a diagnosis of HTN and not taking antihypertensive medication. Intervention: Ambulatory BP patterns are assessed using 24-hour ABPM. Contextual factors are assessed with: ecological momentary assessment (7-item survey of experiences, exposures and responses associated with daytime BP measurements); actigraphy (capturing physical activity and sleep quality); and self-report surveys (assessing physical and social health, environmental and social stressors and supports). Main Outcome Measures: Phenotypes of contextual factors associated with hypertensive BP patterns (sustained HTN, masked HTN, and nocturnal non-dipping). Methods and Results: This study will enroll 500 participants; assessments of blood pressure and contextual factors will be conducted during Waves 2 and 3 of the ECHORN parent study, occurring 2 years apart. In Wave 2, we will assess the association between contextual factors and ABPM patterns. Using advanced analytic clustering methods, we will identify phenotypes of contextual factors associated with hypertensive ABPM patterns. We will then test the stability of these phenotypes and their ability to predict change in ABPM patterns between Waves 2 and 3. Conclusions: Assessment of ABPM, and the contextual factors influencing ABPM, can identify unique phenotypes of HTN, which can then be used to develop more precision-based approaches to the prevention, detection and treatment of HTN in high-risk populations.

BACKGROUND: Several authorities recommend measuring peak expiratory flow (PEF) standing. Limited evidence suggests that PEF obtained sitting is similar in magnitude but there are no studies in African populations. AIM: To determine in adults aged 18-60 years if PEF measured sitting differs from that measured standing. DESIGN & SETTING: Crossover design with alternating position of initial measurement in people attending primary care clinics in Barbados. METHOD: Quota sampling by age, sex, and clinic of adults aged 18-60 years was done and an interviewer-administered questionnaire was completed. PEF sitting and standing was measured with an European Union (EU) scale Mini-Wright® meter. The highest of three readings in each position was used and the difference in means tested for significance using the paired sample t-test. RESULTS: Characteristics of the 199 participants were 44% male; 96.5% of African descent; mean age 37 years (standard deviation [SD] 12.8); 22% with an asthma diagnosis; 23% tobacco users; and 22% marijuana users. Mean PEF standing was 438.4 versus 429.7 lmin-1 sitting, mean difference 8.7 (95% confidence interval [CI] = 3.6 to 13.8). For men, mean PEF standing was 518.7 versus 506.3 lmin-1 sitting, mean difference 12.4 (95% CI = 3.3 to 21.5). For women, mean PEF was 374.7 standing versus 368.9 lmin-1 sitting, mean difference 5.8 (95% CI = 0.11 to 11.5). A Bland-Altman plot accounting for trend and a Lin's correlation coefficient of 0.935 demonstrated good agreement between standing and sitting PEF. CONCLUSION: PEF measurements are reduced when performed sitting compared to standing. The difference is small and unlikely to alter clinical management in most cases.
ABSTRACT
AIM: The purpose of this study was to document in people with type 2 diabetes (T2DM) in Barbados, attitudes and beliefs that may result in psychological insulin resistance. METHODS: A representative, population-based, sample of 175 eligible people with T2DM 25 years of age and over was surveyed by telephone. The 20-item insulin treatment appraisal scale (ITAS) was administered (score range 20 to 100 for positive to negative perceptions). RESULTS: 117 people participated (67% response rate, 32% male, mean age 66 years, 90% Black, 22% on insulin). Of non-responders, 52 were not contactable and 6 were difficult to communicate with. Negative perceptions about insulin use included - meant a worsening of diabetes (68%), would worry family (63%), feared self-injection (58%), meant a failure in self-management (57%), injections were painful (54%), would be seen as being sicker (46%), increased hypoglycaemia risk (38%), required effort (34%), causes weight gain (27%), causes a deterioration in health (14%), and would have to give up enjoyable activities (10%). Positive perceptions were - helps good glycaemic control (78%), would prevent complications (61%) and improves health (58%). Mean total ITAS score (61.6, SD = 7.7) was lower for those on insulin compared to those not on insulin (53.7 vs. 63.8, p < 0.0001). Sex, age and diabetes diagnosis duration were not significant predictors of ITAS score. CONCLUSIONS: Multiple factors related to patient beliefs and attitudes need to be considered and addressed when initiating insulin in order to minimise psychological insulin resistance and delay. Patients using insulin had less negative perceptions than those not on insulin.
ABSTRACT
Context and background: To describe the Family Medicine (FM) postgraduate training programme at the University of the West Indies (UWI). Actions and activities: This paper was created through a review of documents, and discussions with past and present coordinators and key stakeholders at four campuses in the English-speaking Caribbean (ESC). LESSONS LEARNED: Despite intermittent setbacks the FM programme in the ESC has grown due to: (1) The presence of an umbrella institution in the UWI. (2) The role of the Caribbean College of Family Physicians providing a unifying force of advocacy and cooperation. (3) Collaboration of staff across four sites despite large distances, differing departmental and campus structures and financial models; and varying levels of local medical and public health support. (4) The use of a modular design for academic content, which means that students have comparable learning experiences. (5) Streamlining of exit examinations, thus sharing resources in the assessment process. (6) A strong presence of FM in the undergraduate curriculum. CONCLUSIONS: Despite a variety of timelines in programme development and funding mechanisms, over 150 physicians have graduated in FM in the past five years. We identify the unifying strategies and institutions which made this possible and present this model as an option for new programmes in the developing world.

BACKGROUND: In Barbados sexually transmitted infections (STIs) including HIV are not notifiable diseases and there is not a formal partner notification (PN) programme. Objectives were to understand likely attitudes, barriers, and challenges to introducing mandatory disease notification (DN) and partner notification (PN) for HIV and other STIs in a small island state. METHODS: Six key informants identified study participants. Interviews were conducted, recorded, transcribed and analysed for content using standard methods. RESULTS: Participants (16 males, 13 females, median age 59 years) included physicians, nurses, and representatives from governmental, youth, HIV, men's, women's, church, and private sector organisations. The median estimated acceptability by society of HIV/STI DN on a scale of 1 (unacceptable) to 5 (completely acceptable) was 3. Challenges included; maintaining confidentiality in a small island; public perception that confidentiality was poorly maintained; fear and stigma; testing might be deterred; reporting may not occur; enacting legislation would be difficult; and opposition by some opinion leaders. For PN, contract referral was the most acceptable method and provider referral the least. Contract referral unlike provider referral was not "a total suspension of rights" while taking into account that "people need a little gentle pressure sometimes". Extra counselling would be needed to elicit contacts or to get patients to notify partners. Shame, stigma and discrimination in a small society may make PN unacceptable and deter testing. With patient referral procrastination may occur, and partners may react violently and not come in for care. With provider referral patients may have concerns about confidentiality including neighbours becoming suspicious if a home visit is used as the contact method. Successful contact tracing required time and effort. With contract referral people may neither inform contacts nor say that they did not. Strategies to overcome barriers to DN and PN included public education, enacting appropriate legislation to allow DN and PN, good patient counselling and maintaining confidentiality. CONCLUSIONS: There was both concern that mandatory DN and PN would deter testing and recognition of the benefits. Public and practitioner education and enabling legislation would be necessary, and the public needed to be convinced that confidentiality would be maintained.

BACKGROUND: Moderate-intensity exercise improves blood glucose (BG), but most people fail to achieve the required exercise volume. High-intensity exercise (HIE) protocols vary. Maximal cycle ergometer sprint interval training typically requires only 2.5 minutes of HIE and a total training time commitment (including rest and warm up) of 25 minutes per session. The effect of brief high-intensity exercise on blood glucose levels of people with and without diabetes is reviewed. METHODS: HIE (≥80% maximal oxygen uptake, VO2max) studies with ≤15 minutes HIE per session were reviewed. RESULTS: Six studies of nondiabetics (51 males, 14 females) requiring 7.5 to 20 minutes/week of HIE are reviewed. Two weeks of sprint interval training increased insulin sensitivity up to 3 days postintervention. Twelve weeks near maximal interval running (total exercise time 40 minutes/week) improved BG to a similar extent as running at 65% VO2max for 150 minutes/week. Eight studies of diabetics (41 type 1 and 22 type 2 subjects) were reviewed. Six were of a single exercise session with 44 seconds to 13 minutes of HIE, and the others were 2 and 7 weeks duration with 20 and 2 minutes/week HIE, respectively. With type 1 and 2 diabetes, BG was generally higher during and up to 2 hours after HIE compared to controls. With type 1 diabetics, BG decreased from midnight to 6 AM following HIE the previous morning. With type 2 diabetes, a single session improved postprandial BG for 24 hours, while a 2-week program reduced the average BG by 13% at 48 to 72 hours after exercise and also increased GLUT4 by 369%. CONCLUSION: Very brief HIE improves BG 1 to 3 days postexercise in both diabetics and non-diabetics. HIE is unlikely to cause hypoglycemia during and immediately after exercise. Larger and longer randomized studies are needed to determine the safety, acceptability, long-term efficacy, and optimal exercise intensity and duration.
ABSTRACT
BACKGROUND: Deficiencies in the quality of diabetes and hypertension primary care and outcomes have been documented in Barbados. This study aimed to explore the knowledge, attitudes and practices, and the barriers faced by people with diabetes and hypertension in Barbados that might contribute to these deficiencies. METHODS: Five structured focus groups were conducted for randomly selected people with diabetes and hypertension. RESULTS: Twenty-one patients (5 diabetic, 5 hypertensive, and 11 with both diseases) with a mean age of 59 years attended 5 focus group sessions.Patient factors that affected care included the difficulty in maintaining behaviour change. Practitioner factors included not considering the "whole person" and patient expectations, and not showing enough respect for patients. Health care system factors revolved around the amount of time spent accessing care because of long waiting times in public sector clinics and pharmacies. Society related barriers included the high cost and limited availability of appropriate food, the availability of exercise facilities, stigma of disease and difficulty taking time off work.Attendees were not familiar with guidelines for diabetes and hypertension management, but welcomed a patient version detailing a place to record results, the frequency of tests, and blood pressure and blood glucose targets. Appropriate education from practitioners during consultations, while waiting in clinic, through support and education groups, and for the general public through the schools, mass media and billboards were recommended. CONCLUSIONS: Primary care providers should take a more patient centred approach to the care of those with diabetes and hypertension. The care system should provide better service by reducing waiting times. Patient self-management could be encouraged by a patient version of care guidelines and greater educational efforts.

BACKGROUND: Over 19% of the population ≥ 40 years of age in Barbados are diabetic. The quality of diabetes primary care is uncertain. FINDINGS: Charts of diabetic and hypertensive patients were randomly sampled at all public and 20 private sector primary care clinics. Charts of all diabetic patients ≥ 40 years of age were then selected. Processes of care, and quality targets for blood pressure (BP), fasting blood glucose (FBG) and glycosylated haemoglobin (HbA1c) were documented.252 charts of diabetic patients (125 public and 127 private) were audited. Patients had the following characteristics: mean age 64 years, female gender 61%, mean duration of diagnosis 9 years, and hypertension diagnosed 78%. Patients had an average of 4.7 clinic visits per year, 66% were prescribed metformin, 68% a sulphonylurea, 25% a statin, 21% insulin, 15% aspirin and 12% a glucosidase inhibitor. Public patients compared to private patients were more likely to be female (77% vs. 46%, p < 0.01); have a longer duration of diagnosis (11.4 vs. 6.6 years, p < 0.01), have more clinic visits per year (5.2 vs. 4.3, p < 0.01), and to be using insulin (28 vs. 15% p = 0.01). Over a 2 year period, the proportion of charts with the following recorded at least once was: BP 98%, weight 80%, FBG 76%, total cholesterol 72%, urine tested for albumin 66%, serum creatinine 62%, dietary advice 61%, exercise advice 49%, lipid profile 48%, foot examination 41%, HbA1c 33%, dietician referral 23%, retinal examination 18%, tobacco use 17%, body mass index 0%, and waist circumference 0%. Public patients were more likely to have recorded: weight (92% vs. 68%, p = < 0.01); tests for total cholesterol (78% vs. 65%, p = 0.02), albuminuria (72% vs. 59%, p = 0.03), serum creatinine (79% vs. 44%, p < 0.01), and foot examination (50% vs. 32%, p = < 0.01); dietician referral (37% vs. 8%, p < 0.01), and tobacco use (26% vs. 8%, p < 0.01). For those tested, the most recent BP was < 140/90 for 43%, HBA1c was < 7% for 28%, and FBG was < 6.7 mmol/L for 27%. CONCLUSIONS: Interventions such as body mass assessment, lifestyle advice, screening for retinopathy, monitoring blood glucose control, and achieving BP and glycaemic targets need improvement.
ABSTRACT
BACKGROUND: Audits have shown numerous deficiencies in the quality of hypertension and diabetes primary care in Barbados, despite distribution of regional guidelines. This study aimed to evaluate the knowledge, attitudes and practices, and the barriers faced by primary care practitioners in Barbados concerning the recommendations of available diabetes and hypertension guidelines. METHODS: Focus groups using a moderator's manual were conducted at all 8 public sector polyclinics, and 5 sessions were held for private practitioners. RESULTS: Polyclinic sessions were attended by 63 persons (17 physicians, 34 nurses, 3 dieticians, 3 podiatrists, 5 pharmacists, and 1 other), and private sector sessions by 20 persons (12 physicians, 1 nurse, 3 dieticians, 2 podiatrists and 2 pharmacists). Practitioners generally thought they gave a good quality of care. Commonwealth Caribbean Medical Research Council 1995 diabetes and 1998 hypertension guidelines, and the Ministry of Health 2001 diabetes protocol had been seen by 38%, 32% and 78% respectively of polyclinic practitioners, 67%, 83%, and 33% of private physicians, and 25%, 0% and 38% of non-physician private practitioners. Current guidelines were considered by some to be outdated, unavailable, difficult to remember and lacking in advice to tackle barriers. Practitioners thought that guidelines should be circulated widely, promoted with repeated educational sessions, and kept short. Patient oriented versions of the guidelines were welcomed. Patient factors causing barriers to ideal outcome included denial and fear of stigma; financial resources to access an appropriate diet, exercise and monitoring equipment; confusion over medication regimens, not valuing free medication, belief in alternative medicines, and being unable to change habits. System barriers included lack of access to blood investigations, clinic equipment and medication; the lack of human resources in polyclinics; and an uncoordinated team approach. Patients faced cultural barriers with regards to meals, exercise, appropriate body size, footwear, medication taking, and taking responsibility for one's health; and difficulty getting time off work to attend clinic. CONCLUSIONS: Guidelines need to be promoted repeatedly, and implemented with strategies to overcome barriers. Their development and implementation must be guided by input from all providers on the primary health care team.

BACKGROUND: About 55% of the population 40 to 80 years of age in Barbados is hypertensive. The quality of hypertension primary care compared to available practice guidelines is uncertain. FINDINGS: Charts of hypertensive and diabetic patients were randomly sampled at all public and 20 private sector primary care clinics. Charts of all hypertensive patients ≥ 40 years of age were then selected and processes of care and blood pressure (BP) maintenance < 140/90 documented.343 charts of hypertensive patients (170 public, and 173 private) were audited. Patients had the following characteristics: mean age 64 years, female gender 63%, mean duration of diagnosis 9.1 years, and diabetes diagnosed 58%. Patients had an average of 4.7 clinic visits per year, 70% were prescribed a thiazide diuretic, 42% a calcium channel blocker, 40% an angiotensin receptor blocker, and 19% a beta blocker. Public patients compared to private patients were more likely to be female (73% vs. 52%, p < 0.01); have a longer duration of diagnosis (11.7 vs. 6.5 years, p < 0.01), and more clinic visits per year (5.0 vs. 4.5, p < 0.01). Over a 2 year period, the proportion of charts with the following recorded at least once was: BP 98%, weight 80%, total cholesterol 71%, urine tested for albumin 67%, serum creatinine 59%, dietary advice 55%, lipid profile 48%, exercise advice 45%, fasting blood glucose for non-diabetics 39%, dietician referral 21%, tobacco advice 17%, retinal examination 16%, body mass index 1%, and waist circumference 0%. Public patients were more likely to have recorded: weight (92% vs. 68%, p = < 0.01); tests for total cholesterol (77% vs. 67%, p = 0.04), albuminuria (77% vs. 58%, p = < 0.01), serum creatinine (75% vs. 43%, p < 0.01), and fasting blood glucose for non-diabetics (49% vs. 30%, p = 0.02); dietician referral (34% vs. 9%, p < 0.01), and tobacco advice (24% vs. 10%, p < 0.01). Most (92%) diastolic BP readings ended in 0 or 5 (72% ended in 0). At the last visit 36% of patients had a BP < 140/90 mmHg. CONCLUSIONS: Improvements are needed in following guidelines for basic interventions such as body mass assessment, accurate BP measurement, use of thiazide diuretics and lifestyle advice. BP control is inadequate.
ABSTRACT
OBJECTIVE: To predict response rate and validity of a population-based HIV prevalence survey in Barbados using oral fluid, and the method of sample identification preferred by participants. METHODS: Persons age 18 to 35 randomly selected from the voters' register to participate in a study of the prevalence of chlamydia and gonorrhoea (STI) were invited to answer a questionnaire. RESULTS: Of 496 persons selected for the STI study, 88 did not participate, and a further 10 did not answer the questionnaire, leaving 398 respondents. 329 persons or 66% (60% men, 73% women, p = 0.003) of the original 496 persons said that they would be willing to take part in an HIV survey using oral fluid. People indicating willingness to take part in an HIV survey did not differ significantly from non-respondents and those indicating unwillingness to participate by a number of demographic and STI risk factors including age, education level, partnership status, number of partners, condom use, drug use, and STI infection status. For persons willing to participate in a HIV survey, confidential linked sample identification was acceptable to 99.0% (95% CI +/- 1.0), and unlinked identification to 1.6% (95% CI +/- 1.3). CONCLUSION: The HIV prevalence estimated by a linked survey would have a reasonable response rate and be valid, as likelihood of participation is not related to infection risk.
