A systems thinking framework for understanding rising childhood obesity in the Caribbean.

OBJECTIVE: The aim of this study is to develop a systems thinking framework to describe the common complexities of childhood obesity in the Caribbean region and identify potential areas of intervention. METHODS: Group model building (GMB) is a form of systems science. Trained GMB facilitators in Puerto Rico, the US Virgin Islands, Barbados, and Trinidad and Tobago convened a group of multi-disciplinary stakeholders in a series of virtual meetings in 2021 to elaborate a hypothesis of the system driving childhood obesity represented by causal loop diagrams (CLD). Commonalities and differences between the CLDs from each island were identified and reconciled to create a synthesized CLD. RESULTS: A single explanatory CLD across the islands was developed and includes nine reinforcing loops. These loops addressed the interconnected role of schools, policy, commercial determinants, community and the personal experience of the child in rising childhood obesity rates. CONCLUSIONS: Despite differences across settings, there is a core system driving childhood obesity in the Caribbean, as described by stakeholders in GMB workshops. Policy solutions to the problem must be multi-faceted and multi-level to address the interlinked reinforcing loops of the complex system and reduce rates of childhood obesity.

The Effectiveness of Telemedicine in the Management of Chronic Diseases (Diabetes, Hypertension, and Coronary Heart Disease) at Primary Care Facilities in Eastern Trinidad During the COVID-19 Pandemic.

Introduction: During the COVID-19 pandemic, Trinidad and Tobago's government implemented lockdowns and limited the availability of outpatient clinics to curb virus transmission. Subsequently, telemedicine via telephone calls was utilized to address infection control and continuity of care for chronic disease patients. Methods: An observational study was conducted at three primary care facilities in Eastern Trinidad using convenience sampling to review retrospectively telemedicine patients' medical records from October 2019 to February 2020 (before telemedicine) and from March 2020 to September 2020 (during telemedicine) for comparative analysis. Data were analyzed using IBM SPSS Statistics 28.0 software and Microsoft Excel. Results: A total of 199 patient files were analyzed; 57.3% of these were female; 52.3% were 60 years and older. A Wilcoxon signed-rank test demonstrated no statistically significant differences between random blood sugar (RBS) readings (0.355), weight (0.621), or systolic and diastolic blood pressure (BP; 0.239 and 0.232, respectively) before and during the 6-month period of telemedicine consultation. Patients compliant with medication before the use of telemedicine were 14 times more likely to attain target BPs. There was no significant association between compliance with prescribed therapy and BP control (0.335) during the period of telemedicine. Discussion: The findings support the use of telemedicine to manage chronic diseases such as hypertension, diabetes mellitus, and coronary heart disease, as the standard of care was preserved, and no inferiority of recorded outcomes was demonstrated. Although there was an overall decrease in compliance during the telemedicine period compared with before, comparative analysis exhibited no statistically significant differences in BP or RBS readings.

Positive influences of the COVID-19 pandemic on community dwelling adults in Trinidad and Tobago: a cross sectional study.

BACKGROUND: Since the onset of the coronavirus (COVID-19) pandemic its negative effects have been highlighted globally. There is little literature that examines the positive impact on daily living. AIMS: To examine the positive influences of government-imposed COVID-19 public health restrictions on adults throughout Trinidad and Tobago (TT) and their associated factors. METHOD: A cross-sectional study, using an adapted pretested online survey instrument, was conducted amongst non-institutionalised, community-dwelling adults using convenience sampling. RESULTS: Of 1287 completed and weighted responses, the mean age (S.D.) was 39.2 (14.6) years, 49% were males, and 61% completed secondary level education. The top 5 positive experiences were more time spent with family (80%), more down-time (78%), learning new skills (68%), more time for hobbies (66%), self-care (57%), more time spent with friends (55%) and eating healthier (50%). The importance of religion, working from home, and an increase in marijuana use emerged as positive correlates for certain positive experiences, while participants with chronic illness, and a positive anxiety or depression screen, were negatively associated with most positive experiences. CONCLUSIONS: Despite the negative consequences of the COVID19 pandemic, several positives were highlighted in this study. These findings have implications for social policies toward building resilience within the community.

2020 family medicine postgraduate examinations at The University of the West Indies: successes and challenges in the time of COVID-19 pandemic.

Little has been published regarding postgraduate assessments during the COVID-19 pandemic. There is an urgent need to graduate well-trained specialists including family physicians who play a key role in patient care. The successes and challenges encountered in mounting qualifying 2020 Family Medicine examinations during the COVID-19 pandemic at the University of the West Indies are described in this paper. Human resource, planning, use of technology and virtual environments are discussed, which enabled successful examinations at this multicampus regional site.

Effectiveness of personalized written asthma action plans in the management of children with partly controlled asthma in Trinidad: a randomized controlled trial.

BACKGROUND: The provision of written asthma action plans (WAAPs) is regarded by regional and international guidelines as an essential component of patient education and self-management. However, the evidence for this practice in children is deficient. AIM: To evaluate the effectiveness of adding a personalized WAAP in the treatment of children with partly controlled asthma. METHODS: Children with partly controlled asthma were randomized to receive a personalized WAAP or no plan, in addition to standard care including education. They were followed up with serial measurement of outcome variables. The primary outcome measured was the number of emergency room (ER) revisits. RESULTS: Ninety-one children participated, 45 in the intervention group and 46 in the control group. Comparison with pretrial data revealed significantly improved outcomes with respect to the numbers of ER visits ( p = 0.005 and 0.0002) and acute asthmatic attacks ( p = 0.0064 and 0.0006) in both arms of the study. Children in receipt of a personalized WAAP had fewer ER visits ( p = 0.78), asthma attacks ( p = 0.84), missed school days ( p = 0.28), night-time awakenings ( p = 0.48) and unscheduled doctor visits ( p = 0.69) than those who did not receive a plan. CONCLUSION: The results of this study suggest that the provision of personalized WAAPs may play a useful role in the management of children with partly controlled asthma but is no better than standard care. Asthma education is a critical component in the prevention of exacerbations in children with partly controlled asthma.

Knowledge, attitudes, beliefs and practices of pregnant women towards the influenza vaccine in Trinidad.

Background: Pregnant women and their babies are at increased risk of influenza-related complications. The World Health Organisation recommends influenza vaccination to this high-risk population as the highest priority. Methods: A knowledge, attitudes,beliefs, and practices (KAP) of pregnant women towards the influenza vaccine in Trinidad. It was disseminated to 480 pregnant women attending the clinic and completed by 146 yielding a response rate of 30%. Results: Women who received the vaccine in a past pregnancy were nine times more likely to consider taking the vaccine in the current pregnancy. There was a statistically significant difference in vaccine uptake based on the source of information received by participants about the influenza vaccine (χ2 (3) = 9.864, P = 0.020), with the highest mean score for uptake shown in women who received information from a health care provider. A moderate, positive correlation was found between knowledge and vaccine uptake (rs (143) =0.430, P < 0.01), a weak, positive correlation between perceived susceptibility and vaccine uptake (rs (143) = 0.264, P < 0.01), and a weak, positive correlation between knowledge and perceived susceptibility (rs (143) = 0.229, P < 0.01). Conclusion: The study findings highlight that the source of information significantly influences vaccine uptake, with health care providers being the most influential source. This underscores the role of primary care physicians in providing accurate and up-to-date information about influenza vaccination to pregnant women. There is a need for accurate information and recommendations to be given to pregnant women by all health care workers including primary care physicians in order to increase vaccine uptake and reduce maternal and neonatal morbidity and mortality.

A cross-sectional study on the quality of life of women with endometriosis in Trinidad and Tobago.

Introduction: Endometriosis is a chronic gynecological condition that lacks a definitive cure and adversely impacts the quality of life (QoL) of those affected. This study delves into the experiences of individuals with endometriosis in Trinidad and Tobago, focusing on their quality of life, pain severity, and acceptance of illness. Methods: Surveys were distributed among 160 members of the Trinidad and Tobago Endometriosis Association. The survey instrument utilized was the WHOQOL-BREF, which measures QoL, pain severity, and acceptance of illness [the Acceptance of Illness Scale (AIS)]. Results: The average age of respondents was 38.65 years. Quality of life scores averaged 3.41, with the "environment" aspect scoring highest (12.84) and "social relationships" scoring lowest (11.88). Cronbach's alpha indicated excellent internal consistency for "environment" (ɑ = 0.909) and the "AIS" (ɑ = 0.882). The independent samples t-test revealed lower mean QoL scores for unemployed participants. Analysis of variance revealed significant differences in mean QoL scores for "health status" and "years since endometriosis diagnosis." All the QoL domains were positively correlated with each other. There were moderate positive correlations between the physical health and social relationships domains (ρ = 0.558). All other domains were strongly correlated with each other (0.6 < ρ < 0.8). Pain intensity and acceptance of illness had mean scores of 24.15 and 6.57, respectively. Variations in quality of life were observed for health status and duration since diagnosis, impacting mostly on the domain of physical health. Acceptance of illness emerged as a significant influencer of overall quality of life, assisting individuals in navigating the challenges posed by endometriosis. Discussion: The findings underscore the importance of understanding determinants, such as pain severity to improve care and support for those with endometriosis. Exploring acceptance of illness is critical in improving the quality of life of these individuals, highlighting the need for tailored interventions that encompass psychological and social support alongside medical treatment. This study demonstrates the pivotal role of acceptance of illness in the overall quality of life of endometriosis patients. Improving the quality of care requires a comprehensive understanding of the factors influencing quality of life, particularly pain severity and the need for a holistic approach to support individuals grappling with endometriosis.

A retrospective study of prostate-specific antigen and international prostate symptoms scores from participants at a men's health screening initiative in Trinidad.

Background: This study describes the characteristics of men attending a primary health care screening initiative, determines the proportion of men who have elevated International Prostate Symptom Score (IPSS) scores and prostate-specific antigen (PSA) levels, and determines any correlation between these scores as indicators for benign prostatic hyperplasia (BPH) or prostate cancer. Methods: Data were collected from all patient records during men's health screening initiatives that occurred in December 2018, January 2019, and March 2019 in Trinidad and Tobago. A total of 350 medical records were analyzed to record patient demographics, PSA levels, and IPSS scores. Analysis of the data was performed with the use of Statistical Package for the Social Sciences software (version 27). Results: Most men who attended the screening initiative belonged to the 61-65 age group (20.57%), with more than half of the men being married (57.71%) and employed (52.57%) and of patients with comorbidities (17%), the most prevalent included hypertension (6%) and diabetes mellitus (3.7%). A mean PSA level of 2.94 ng/ml and a mean IPSS of 7.62 were recorded. Moreover, 11.5% of the males had elevated PSA levels (>4 ng/ml) and 32.9% had elevated IPSS levels (>8). There were correlations between PSA and IPSS values (r = 0.161 and P = 0.006). Age was a predictor of both IPSS and PSA values (r = 0.214, P = 0.000 and r = 0.192, P = 0.000, respectively). Among diabetic participants, a small but significant correlation between IPSS and diabetes was shown (r = 0.223, P = 0.028). As a predictor of elevated IPSS, diabetes had an odds ratio of 1.132 (95% confidence interval (CI): 1.021-1.255). Conclusion: Our findings are similar to those described in previous studies; however, further investigations are required to fully describe the relationship between PSA and IPSS. This may assist in advancing screening measures and improving health outcomes for men with BPH and prostate cancer. Primary care physicians should recognize the possible association between BPH and diabetes mellitus and offer appropriate screening where indicated.

A No-Cost, Bedside, Self-Traction Maneuver for Relief From Chronic Cervical Radiculopathy: A Case Report.

Cervical radiculopathy secondary to spondylosis is common in the elderly. Systematic reviews suggest that no single treatment modality represents the standard of care. A no-cost, bedside, self-traction intervention can be a useful adjunct to current options. A 60-year-old South Asian male presented with severe cervical radiculopathic pain in April 2019, proven by magnetic resonance imaging to be secondary to spondylosis. Since late 2019, he has been doing a daily self-traction procedure in which he lies prone with the anterior chest and abdomen flat on a bed, shoulders just off the mattress edge, and arms to the side. The position is maintained for 60 seconds, where the weight of the head provides traction. Overhead cervical traction has not been needed for the past three years, and the pain has been bearable. His Neck Disability Index has decreased from 25 to 2. This no-cost, minute-long daily maneuver has provided relief from chronic cervical neuropathic pain due to cervical spondylosis.

Are primary care consultations in Trinidad patient-centered? A cross-sectional study of patients with non-communicable diseases.

BACKGROUND: The aim of this study was to measure the patient's perception of patient centeredness in their consultations for non-communicable diseases (NCDs). We also measured consultation length and patient enablement. METHOD: A cross-sectional study was conducted over 2 months at four primary care clinics at the St. Joseph cluster of the North Central Regional Health Authority (NCRHA) in Trinidad and Tobago. Interviewers timed the consultation and completed post-consultation questionnaires using the Patient Perception of Patient-Centeredness (PPPC) questionnaire and the Patient Enablement Index (PEI). The PPPC is a 14-item (each scored 1-4) Likert-scaled instrument. The total score is averaged and a PPPC score of 4 is the maximum. The PEI measures the ability of the patient to cope with life and their disease. The PEI consists of 6 questions scored 0-2, with a maximum score of 12. RESULTS: There were 180 respondents (response rate = 82.5%). Participants were female (75.6%), aged over 65 years (50.6%), married (51.1%), Indo-Trinidadian (52.2%), and Christian (60.6%). Half achieved a primary school education, and 37.2% secondary. The consultation length ranged between 1.32 and 31.22 min. The average, median and mode of the consultation length were 8.5, 7.74 and 10 min, respectively. The average, median and mode of the measures of patient-centeredness were PPPC (3.67, 3.86 and 4) and PEI score (5.93, 6 and 6). The PPPC average was lower in patients with a stroke (p = 0.022), and higher among those with more than 2 consultation interruptions (p = 0.015) and those who knew the doctor very well (p = 0.015). The PEI score was lower in patients with heart disease (p = 0.022). The consultation length was longer in those with tertiary education (p = 0.044) and those with two consultation interruptions (p = 0.032). PPPC Average and PEI Score correlated well (ρ = 0.408, p < 0.001). The consultation length correlated with the PPPC Average (ρ = 0.168,p = 0.025). CONCLUSION: Primary Care consultations in this cluster of health centres in NCRHA in Trinidad were often patient centered. The consultation length, patient-centeredness, measured with the PPPC instrument, and patient enablement scores, measured with the PEI instrument, in consultations for NCDs in Trinidad compare favourably with international reports.

The knowledge, attitudes, and perceptions toward the Oxford AstraZeneca COVID-19 vaccine amongst Primary Health care workers in North-Central Trinidad.

Aim: To determine the effects of knowledge, attitudes, and perceptions of primary care health workers toward receiving the Oxford AstraZeneca vaccine in North Central, Trinidad. Methods: A pretested de novo questionnaire containing forty-eight (48) closed ended questions and one (1) open ended question was used to gather data. Descriptive and inferential statistics were used to analyze the data obtained from the questionnaire. These included percentages, means and standard deviations for the descriptive aspect and the Chi-Square test to examine any significant associations. Analysis of Variance (ANOVA) was used to assess any significant differences in means among several categories and the independent samples t-test for assessing any significant difference in means between two categories. Results: 273 respondents completed the questionnaire. Most of the participants (72.2%) were female and within the age range 25-36 (56.0%). The mean knowledge score about the AstraZeneca vaccine was 16.28 (SD = 2.28) out of 19 with an overall correct response rate of 79%. 30.4% of participants had a good attitude score and 59.7% had a positive perception toward the AstraZeneca vaccine. There were significant associations between knowledge and marital status (p = 0.001), income level (p = 0.001), education level (p < 0.001), and length of employment (p = 0.041); attitudes and sex (p = 0.01), age (p = 0.04), marital status (p = 0.009), income level (p < 0.001), education level (p = 0.005) and category of staff (p < 0.001); perception and sex (p = 0.002), marital status (p = 0.027), income level (p < 0.001), and category of staff (p < 0.001). Conclusions: The main contributors to vaccine hesitancy were inadequate duration of clinical trials and fear of adverse side effects. A significant number of participants (17%) were unwilling to get the vaccine due to lack of information.

Investigating the leading reasons for primary health care encounters and its implications for health care in Trinidad and Tobago. A systematic review.

This systematic review aims at offering a comparative analysis of the leading reasons for encounters (RFEs) of patients presenting to primary care facilities. A systemic search was carried out using MEDLINE/PUBMED, CINAHL, Google Scholar, LILACS, and PROQUEST to identify the studies relevant to RFEs in primary health care in June 2020. Fifteen studies met the eligibility criteria which included originality, published between 2015 and 2020, listed two to five RFEs at a primary health care facility, and included patients with acute and/or chronic conditions. The mean total RFEs recorded were 6753.07 (Standard deviation = 17446.38, 95% Confidence Interval 6,753.0667 ± 8,829.088 [± 130.74%]). The most common RFE chapters recorded were Respiratory and Digestive chapters. The patients recorded fever as the most frequently reported RFE while cough was ranked as most common. The physicians reported hypertension as the most frequently reported and most common RFE. The most frequently physician and patient reported RFEs to the primary health care are hypertension and fever. Respiratory and Digestive were the most frequently reported chapters. The findings are useful for the proper implementation of services, facilities, and equipment utilized in Trinidad and Tobago primary health care.

Eight years of antibiotic consumption at a primary care outpatient facility in Trinidad and Tobago 2011-18: a synopsis of consumption trends.

OBJECTIVES: To explore antibiotic consumption and surveillance patterns in Trinidad and Tobago. METHODS: A retrospective observational study was conducted. Stock requisition and logbooks from a District Health Facility in Trinidad were examined for the period 2011-18. Daily Defined Doses (DDDs) for each antibiotic were computed and extrapolated to represent the antibiotic consumption per 1000 residents within the population. RESULTS: The mean consumption across the years was 2.917 DDD per 1000 residents per day. The most consumed antibiotics were cefuroxime, amoxicillin/clavulanic acid, and azithromycin, with mean DDDs of 0.879, 0.695 and 0.373 respectively. The least consumed antibiotics were cefaclor and clarithromycin, with DDDs of 0.0006 and 0.0005, respectively. CONCLUSIONS: Trinidad and Tobago is not mentioned in the WHO surveillance report on antibiotic consumption. Our most recent (2018) estimate of total antibiotic consumption was 3.224 DDD per 1000 habitants per day. This figure is an underestimate, as data was derived solely from the public sector. Notwithstanding, this data is novel and can provide a baseline for future comparison and development of national surveillance programmes.

Prevalence rates of impaired glucose tolerance and gestational diabetes mellitus amongst expectant mothers and undiagnosed diabetes mellitus in walk-in patients at health centres in North Central Trinidad.

OBJECTIVE: To assess the prevalence rates of impaired glucose tolerance and gestational diabetes among expectant mothers, as well as the prevalence rate of undiagnosed diabetes mellitus in walk-in patients at selected health centres in North Central Trinidad. DESIGN: A cross-sectional study over the period January 2012 to December 2016. SETTING: Primary health care centres. SAMPLE POPULATION: Pregnant women aged 18-45 years who were within their second and third trimester of pregnancy, and for undiagnosed diabetes mellitus the sample population consisted of males and females over the age of 18. METHODOLOGY: Medical records of 90 pregnant women and 174 walk-in patients who received care at the selected health centres during the period January 2012 to December 2016 were examined and the following were recorded: age, ethnicity, parity, gravidity, past medical/surgical history, past obstetric history, oral glucose tolerance test results, random blood glucose results, HbA1c results, and family history of diabetes mellitus (DM). RESULTS: The sample population was 90 expectant mothers and 174 walk-in patients. However, valid results were available for 50 expectant mothers and 78 walk-in patients. Of the 50 valid results for expectant mothers, 1 mother had a confirmed diagnosis recorded for gestational diabetes mellitus (GDM) yielding a prevalence of 2% for GDM. Age was positively correlated with the diagnosis of impaired glucose tolerance (IGT). (P = 0.028). Of the 141 valid entries for walk-in patients, 25 had a confirmed diagnosis of DM yielding a prevalence of ~ 18% for undiagnosed DM. A family history of diabetes was positively correlated with a subsequent diagnosis of DM among previously undiagnosed diabetes. CONCLUSION: The prevalence rate for GDM was found to be 2% and the prevalence rate for undiagnosed DM in walk-in patients was 18%.

Investigating the risk of Incident diabetes mellitus among primary care patients treated with simvastatin in North-Central Trinidad.

AIM: To determine the risk of new-onset diabetes mellitus in patients treated with simvastatin at primary healthcare clinics in North Central Trinidad. MATERIALS AND METHODS: A retrospective descriptive case-series study design was applied to 384 conveniently sampled patient medical records from the cluster of primary healthcare centers during the period of February 2016-May 2016. Information from the patient files were then recorded using a systematic data extraction form. The major inclusion criteria were non-diabetic patients who were compliant with daily simvastatin for a minimum period of 1 year. The risk of incident diabetes mellitus was calculated, using SPSS version 20.0. Chi-squared (χ2) testing was performed to determine any association between new-onset diabetes mellitus and simvastatin use. RESULTS: In all, 207 patients became diabetic during their treatment period translating into a 53.9% risk of incident diabetes mellitus (χ2 = 2.3438, P = 0.1258). A subgroup analysis of 133 subjects was performed to eliminate the confounders of family history of diabetes and age greater than 60 years. In this subgroup, 50 incident diabetics (37%) were identified and a statistically significant association was observed (χ2 = 8.118, P = 0.0042). Linear regression revealed that this association was dose-dependent with a corresponding 32% higher risk in patients taking 40 mg (P = 0.001) of simvastatin daily compared with 20 mg of simvastatin (P = 0.094). Linear regression also revealed that there was significant statistical association between onset of diabetes mellitus and duration of statin therapy (P = 0.006). CONCLUSION: In this population, simvastatin use is associated with a 53.9% increased risk of development of new-onset diabetes mellitus (χ2 = 2.3438, P = 0.1258). A statistically significant association was attained after subgroup analysis involving patients less than 60 years old and without a family history of diabetes with an incident risk of 37%. The increased risk of incident diabetes mellitus conferred by higher doses of simvastatin warrants consideration by physicians considering therapies for dyslipidemia in patients with multiple risk factors for diabetes mellitus.

Microbial quality of "doubles" sold in Trinidad

A cross-sectional study was conducted to determine the prevalence and characteristics of Escherichia coli, Staphylococcus aureus, Bacillus spp. and Salmonella spp. in "bara", "channa", condiments/spices and ready-to-eat "doubles" sold by vendors in the St. George and Caroni counties of Trinidad. Of 196 samples of each of "bara", "channa", condiments/spices and ready-to-eat "doubles" examined, E. coli was detected in 0 (0.0 per cent), 14 (7.1 per cent), 96 (49.0 per cent) and 67 (34.2 per cent), respectively; Staphylococci were isolated from 104 (53.1 per cent), 71 (36.2 per cent), 129 (65.8 per cent) and 123 (62.8 per cent) samples, respectively; and Bacillus spp. were recovered from 22 (11.2 per cent), 85 (43.4 per cent), 100 (51.0 per cent) and 88 (44.9 per cent) samples, respectively. Salmonella spp. were not isolated from any sample. Of the 177 isolates of E. coli recovered from all sources, 9 (5.1 per cent), 7 (4.0 per cent) and 47 (26.6 per cent) were mucoid, haemolytic and non-sorbitol fermenters (NSF), respectively, but none agglutinated with O157 antiserum. Of 427 staphylococcal isolates, 130 (30.4 per cent) were confirmed as S. aureus of which 20 (15.4 per cent) were haemolytic and 84 (64.6 per cent) pigmented, while 17 (20.7 per cent) of 82 strains of S. aureus tested produced enterotoxins. Ready-to-eat "doubles", a popular food in Trinidad, therefore pose a potential health risk to consumers due to the high level of contamination with bacteria.

The effectiveness of Telemedicine on the Management of Chronic Diseases (Diabetes, Hypertension and Coronary Heart Disease) at ERHA Primary Health Care Facilities during the COVID-19 pandemic

During the COVID-19 pandemic, Trinidad and Tobago's Government implemented lockdowns and limited outpatient clinics to curb virus transmission. For those with comorbidities (eg.DM, HTN, heart conditions), the risk of severe illness and fatality is increased'. Hence, a niche for telemedicine developed to address infection control and the continuity of care of chronic disease patients. At the ERHA, a Telemedicine initiative was introduced at primary health centres in late 2020. Hence,our group decided to perform a comparative 6 month study to analyse chronic disease outcomes and to assess the effectiveness of telemedicine.
