Evaluating elimination of mother-to-child transmission of HIV in Suriname: a mixed method study / Estudio con métodos mixtos para evaluar la eliminación de la transmisión maternoinfantil del VIH en Suriname / Avaliação da eliminação da transmissão materno-infantil do HIV no Suriname: estudo de métodos mistos

ABSTRACT Objectives. To evaluate the cascade of care for the elimination of mother-to-child-transmission of human immunodeficiency virus (HIV) in Suriname and identify sociodemographic and clinical factors preventing transmission to exposed infants. Methods. A mixed-methods study design was used. Antenatal care data from the 2018 cross-sectional multi-indicator cluster survey on 1 026 women aged 15-49 years who had had a live birth in the previous 2 years were used. Furthermore, national data on a cohort of 279 mothers with HIV and their 317 infants born from 2016 to 2018 were evaluated. Additionally, 13 cases of mother-to-child-transmission of HIV were reviewed. Results. In 89.3% of cases, no mother-to-child HIV transmission occurred. Early cascade steps show that 28.4% of women had unmet family planning needs, 15% had no antenatal visits, 8% delivered outside a health facility, and 71.5% received an HIV test during antenatal care. Of the pregnant women with HIV, 84.2% received antiretroviral therapy, while 95.5% of their infants received HIV prophylactic treatment. Receiving antiretroviral therapy for the mother (odds ratio (OR) 45.4, 95% confidence interval (CI) 9.6-215.3) and the child (OR 145.7, 95% CI 14.4-1477.4) significantly increased the odds of a negative HIV test result in infants. Conversely, living in the interior decreased the odds (OR 0.2, 95% CI 0.4-0.7) compared with urban living. Conclusions. HIV medication for mothers with HIV and their infants remains key in the prevention of mother-to-child-transmission of HIV. Early prenatal care with follow-up should be strengthened in Suriname.

RESUMEN Objetivos. Evaluar la secuencia de la atención para la eliminación de la transmisión maternoinfantil del virus de la inmunodeficiencia humana (VIH) en Suriname y determinar los factores sociodemográficos y clínicos que previenen la transmisión a lactantes expuestos al virus. Métodos. En este estudio se empleó un diseño de métodos mixtos. Se utilizaron los datos de atención prenatal procedentes de la encuesta transversal de indicadores múltiples por conglomerados del 2018, realizada en 1 026 mujeres de entre 15 y 49 años que habían dado a luz a un nacido vivo en los dos años anteriores. También se evaluaron los datos nacionales correspondientes a una cohorte de 279 madres con infección por el VIH y sus 317 bebés nacidos entre el 2016 y el 2018. Además, se analizaron en detalle 13 casos de transmisión maternoinfantil del VIH. Resultados. En el 89,3% de los casos no hubo transmisión maternoinfantil del VIH. En las etapas iniciales de la secuencia de la atención se observó que el 28,4% de las mujeres no tenían cubiertas sus necesidades de planificación familiar; además, el 15% no dispusieron de consultas de atención prenatal, el 8% dieron a luz fuera de un centro de salud y en el 71,5% se llevó a cabo una prueba de detección del VIH en el marco de la atención prenatal. De las mujeres embarazadas con infección por el VIH, el 84,2% recibió un tratamiento antirretroviral, mientras que el 95,5% de los bebés recibieron un tratamiento profiláctico contra el VIH. La administración de tratamiento antirretroviral a la madre (cociente de posibilidades [OR] = 45,4; intervalo de confianza [IC] del 95%: 9,6-215,3) y al bebé (OR = 145,7; IC del 95%: 14,4-1477,4) hizo que aumentaran significativamente las posibilidades de obtener un resultado negativo en la prueba de detección del VIH en los lactantes. Por el contrario, residir en el interior del país hizo que disminuyeran dichas posibilidades (OR = 0,2; IC del 95%: 0,4-0,7), en comparación con residir en un entorno urbano. Conclusiones. Para las madres con infección por el VIH y para sus bebés, los medicamentos contra el VIH siguen siendo esenciales para prevenir la transmisión maternoinfantil del VIH. En Suriname debe reforzarse la atención prenatal temprana, incluido el seguimiento.

RESUMO Objetivos. Avaliar a cascata de atendimento para a eliminação da transmissão materno-infantil do vírus da imunodeficiência humana (HIV) no Suriname e identificar fatores sociodemográficos e clínicos que impedem a transmissão a bebês expostos. Métodos. Foi utilizado um delineamento de estudo com métodos mistos. Foram usados dados de atendimento pré-natal de uma pesquisa de indicadores múltiplos por conglomerados de corte transversal realizada em 2018, que incluiu 1 026 mulheres com idades entre 15 e 49 anos que haviam tido um nascido vivo nos dois anos anteriores. Além disso, foram avaliados os dados nacionais de uma coorte de 279 mães com HIV e seus 317 bebês nascidos vivos de 2016 a 2018, além de 13 casos de transmissão materno-infantil de HIV. Resultados. Em 89,3% dos casos, não houve transmissão materno-infantil do HIV. As etapas iniciais da cascata demonstram que 28,4% das mulheres tiveram necessidades não atendidas de planejamento familiar, 15% não fizeram consultas pré-natais, 8% tiveram o parto fora de uma unidade de saúde e 71,5% receberam um teste de HIV durante o atendimento pré-natal. Das gestantes com HIV, 84,2% receberam terapia antirretroviral, e 95,5% de seus bebês receberam tratamento profilático para o HIV. O tratamento antirretroviral da mãe (razão de chances [RC]: 45,4; intervalo de confiança [IC] de 95%: 9,6-215,3) e da criança (RC: 145,7; IC 95%: 14,4-1477,4) aumentou significativamente a probabilidade de um resultado negativo no teste de HIV dos bebês. Por outro lado, morar no interior diminuiu a probabilidade (RC: 0,2; IC 95%: 0,4-0,7) em comparação com o ambiente urbano. Conclusões. A medicação de mães e bebês contra o HIV continua sendo fundamental para a prevenção da transmissão materno-infantil do HIV. Deve-se reforçar o atendimento pré-natal precoce com acompanhamento no Suriname.

Seen through the patients' eyes: surgical safety and checklists.

OBJECTIVE: We sought to explore the views patients have towards surgical safety and checklists. As a secondary aim, we explored if previous experience of error or other patient characteristics influence these views. DESIGN: A cross-sectional survey study design was applied. PARTICIPANTS: The Flemish Patients' Platform network and social media were used to recruit participants. MAIN OUTCOME MEASURE(S): An 11-item questionnaire was designed to assess the following constructs: perception of surgical safety, attitudes towards the WHO surgical safety checklist and attitudes regarding checklist usage. RESULTS: Respondents' view (N = 444) on the risk of an adverse event showed considerable variation. Respondents were positive towards the checklist, strongly agreeing that it would impact positively on their safety. However, this positive perception did not translate into an attitude where patients will actively inform themselves whether a checklist is used. The majority of respondents have no difficulty with repetitive verification of identity, procedure and location of the surgery. Respondents with a clinical background were the least anxious. Views were divided regarding hearing discussions around blood loss or airway problems. CONCLUSIONS: Patients perceive the checklist as a reliable safety tool. They do not mind repetitive verification of identity and procedure. However, hearing staff discussing specific, explicit, risks could cause anxiousness in some patients. Building a supportive and collaborative environment is needed to involve and empower patients to contribute in the realization of a safe hospital environment.

Validation of the flemish CARES, a quality of life and needs assessment tool for cancer care.

BACKGROUND: The Cancer Rehabilitation Evaluation System (CARES) is a quality of life (QOL) and needs assessment instrument of US origin that was developed in the 90's. Since November 2012 the copyright and user fee were abolished and the instrument became publicly available the present study aims to reinvestigate the psychometric properties of the CARES for the Flemish population in Belgium. METHODS: The CARES was translated into Flemish following a translation-back translation process. A sample of 192 cancer patients completed the CARES, concurrent measures, and questions on socio-demographic and medical data. Participants were asked to complete the CARES a second time 1 week later, followed by some questions on their experiences with the instrument. Internal consistency, test-retest reliability, content validity, construct validity, concurrent validity and feasibility of the CARES were subsequently assessed. RESULTS: The Flemish CARES version demonstrated excellent reliability with high internal consistency (range .87-.96) and test-retest ratings (range .70-.91) for all summary scales. Factor analysis replicated the original factor solution of five higher order factors with factor loadings of .325-.851. Correlations with other instruments ranging from |.43|-|.75| confirmed concurrent validity. Feasibility was indicated by the low number of missing items (mean 2.3; SD 5.0) and positive feedback of participants on the instrument. CONCLUSIONS: The Flemish CARES has strong psychometric properties and can as such be a valid tool to assess cancer patients' QOL and needs in research, for example in international comparisons. The positive feedback of participants on the CARES support the usefulness of this tool for systematic assessment of cancer patients' well-being and care needs in clinical practice. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02282696 (July 16, 2014).

Assessing cancer patients' quality of life and supportive care needs: Translation-revalidation of the CARES in Flemish and exhaustive evaluation of concurrent validity.

BACKGROUND: The prevalence of cancer increases every year, leading to a growing population of patients and survivors in need for care. To achieve good quality care, a patient-centered approach is essential. Correct and timely detection of needs throughout the different stages of the care trajectory is crucial and can be supported by the use of screening and assessment in a stepped-care approach. The Cancer Rehabilitation Evaluation System (CARES) is a valuable and comprehensive quality of life and needs assessment instrument. For use in Flemish research and clinical practice, the CARES tool was translated for the Dutch-speaking part of Belgium (Flanders) from its original English format. This protocol paper describes the translation and revalidation of this Flemish CARES version. METHODS: After forward-backward translation of the CARES into Flemish we aim to recruit 150 adult cancer patients with a primary cancer diagnosis (stage I, II or III) for validation. In this study with a combination of qualitative and a quantitative approach, qualitative data will be collected through focus groups and supplemented by two phases of quantitative data collection: i) an initial patient survey containing questions on socio-demographic and medical data, the CARES and seven concurrent instruments; and ii) a second survey administered after 1 week containing the CARES and supplementary questions to explore their impressions on the content and the feasibility of the CARES. DISCUSSION: With this extensive data collection process, psychometric validity of the Flemish CARES can be tested thoroughly using classical test theory. Internal consistency of summary scales, test-retest reliability, content validity, construct validity, concurrent validity and feasibility of the instrument will be examined. If the Flemish CARES version is found reliable, valid and feasible, it will be used in future research and clinical practice. Comprehensive assessment with the CARES in a stepped-care approach can facilitate timely identification of cancer patients' psychosocial concerns and care needs so it can contribute to efficient provision of patient-centered quality care.

Resilience as a predictor for emotional response to the diagnosis and surgery in breast cancer patients.

OBJECTIVE: The purposes of the present study were to investigate the role of resilience in the prediction of emotional response in breast cancer patients and to examine whether this association is specific for women undergoing this emotionally taxing condition or whether resilience is more generally associated with higher levels of emotional well-being. METHODS: Two hundred fifty-three breast cancer patients and 211 healthy female controls completed four psychological questionnaires. Measures comprised the Connor-Davidson Resilience Scale, the Hospital Anxiety and Depression Scale, Positive and Negative Affect Schedule, and two happiness items. Cancer patients were assessed after diagnosis and surgery. RESULTS: Cancer patients reported higher levels of anxiety, depression, and negative affect and lower levels of positive affect and current happiness compared with control women. There was no difference between the two groups in level of resilience. Higher levels of resilience were related to better emotional adjustment both in women with breast cancer and in control women, but this association was stronger within the sample of cancer patients. In fact, patients scoring high on resilience seemed to experience similar levels of anxiety, depression, and current happiness as healthy women. CONCLUSION: Our results confirm that resilience may at least partially protect against emotional distress in cancer patients. Our findings suggest that resilience may be a relatively stable trait that is not affected by adversity.

One fourth of unplanned transfers to a higher level of care are associated with a highly preventable adverse event: a patient record review in six Belgian hospitals.

OBJECTIVE: The objectives of this study are to determine the prevalence and preventability of adverse events requiring an unplanned higher level of care, defined as an unplanned transfer to the ICU or an in-hospital medical emergency team intervention, and to assess the type and the level of harm of each adverse event. DESIGN: A three-stage retrospective review process of screening, record review, and consensus judgment was performed. SETTING: Six Belgian acute hospitals. PATIENTS: During a 6-month period, all patients with an unplanned need for a higher level of care were selected. INTERVENTIONS: The records 6-month period, the records of all patients with an unplanned need for a higher level of care were assessed by a trained clinical team consisting of a research nurse, a physician, and a clinical pharmacist. MEASUREMENTS AND MAIN RESULTS: Adverse events were found in 465 of the 830 reviewed patient records (56%). Of these, 215 (46%) were highly preventable. The overall incidence rate of patients being transferred to a higher level of care involving an adverse event was 117.6 (95% CI, 106.9-128.3) per 100,000 patient days at risk, of which 54.4 (95% CI, 47.15-61.65) per 100,000 patient days at risk involving a highly preventable adverse event. This means that 25.9% of all unplanned transfers to a higher level of care were associated with a highly preventable adverse event. The adverse events were mainly associated with drug therapy (25.6%), surgery (23.7%), diagnosis (12.4%), and system issues (12.4%). The level of harm varied from temporary harm (55.7%) to long-term or permanent impairment (19.1%) and death (25.2%). Although the direct causality is often hard to prove, it is reasonable to consider these adverse events as a contributing factor. CONCLUSION: Adverse events were found in 56% of the reviewed records, of which almost half were considered highly preventable. This means that one fourth of all unplanned transfers to a higher level of care were associated with a highly preventable adverse event.

Variability of patient safety culture in Belgian acute hospitals.

OBJECTIVES: The aim of this study was to measure differences in safety culture perceptions within Belgian acute hospitals and to examine variability based on language, work area, staff position, and work experience. METHODS: The Hospital Survey on Patient Safety Culture was distributed to hospitals participating in the national quality and safety program (2007-2009). Hospitals were invited to participate in a comparative study. Data of 47,136 respondents from 89 acute hospitals were used for quantitative analysis. Percentages of positive response were calculated on 12 dimensions. Generalized estimating equations models were fitted to explore differences in safety culture. RESULTS: Handoffs and transitions, staffing, and management support for patient safety were considered as major problem areas. Dutch-speaking hospitals had higher odds of positive perceptions for most dimensions in comparison with French-speaking hospitals. Safety culture scores were more positive for respondents working in pediatrics, psychiatry, and rehabilitation compared with the emergency department, operating theater, and multiple hospital units. We found an important gap in safety culture perceptions between leaders and assistants within disciplines. Administration and middle management had lower perceptions toward patient safety. Respondents working less than 1 year in the current hospital had more positive safety culture perceptions in comparison with all other respondents. CONCLUSIONS: Large comparative databases provide the opportunity to identify distinct high and low scoring groups. In our study, language, work area, and profession were identified as important safety culture predictors. Years of experience in the hospital had only a small effect on safety culture perceptions.

Comparing the effectiveness of two cardiovascular prevention programmes for highly educated professionals in general practice: a randomised clinical trial.

BACKGROUND: Cardiovascular disease is a major cause of mortality and morbidity and its prevalence is set to increase. While the benefits of medical and lifestyle interventions are established, the effectiveness of interventions which seek to improve the way preventive care is delivered in general practice is less so. The aim was to study and to compare the effectiveness of 2 intervention programmes for reducing cardiovascular risk factors within general practice. METHODS: A randomised controlled trial was conducted in Belgium between 2007-2010 with 314 highly educated and mainly healthy professionals allocated to a medical (MP) or a medical + lifestyle (MLP) programme. The MP consisted of medical assessments (screening and follow-up) and the MLP added a tailored lifestyle change programme (web-based and individual coaching) to the MP. Primary outcomes were total cholesterol, blood pressure, and body mass index (BMI). The secondary outcomes were smoking status, fitness-score, and total cardiovascular risk. RESULTS: The mean age was 41 years, 95 (32%) participants were female, 7 had a personal cardiovascular event in their medical history and 3 had diabetes. There were no significant differences found between MP and MLP in primary or secondary outcomes. In both study conditions decreases of cholesterol, systolic blood pressure, and diastolic blood pressure were found. Unfavourable increases were found for BMI (p < .05). A significant decrease of the overall cardiovascular risk was reported (p < .001). CONCLUSIONS: Both interventions are effective in reducing cardiovascular risk. In our population the combined medical and lifestyle programme was not superior to the medical programme. TRIAL REGISTRATION: ISRCTN23940498.

Prevalence of atrial fibrillation in adults participating in a large-scale voluntary screening programme in Belgium.

OBJECTIVE: Atrial fibrillation (AF) is a common arrhythmia in clinical practice. AF fulfils many of the criteria for a screening programme. No data about the prevalence of AF in non-hospitalized patients are available in Belgium. The aim of the study was to assess feasibility and effectiveness of a nationwide-organized voluntary screening programme in the general population in Belgium. METHODS: A total of 13.564 participants were screened, of whom 10,758 were older than 40 years (GSP group). Participants filled in stroke risk stratification questionnaires (CHADS2 and CHA2DS2-VASc). A one-lead electrocardiogram was performed. RESULTS: 228 participants had AF at the time of screening (AF group), with 125 women and 103 men (i.e., 1.9% and 2.6% of total women and men), representing a prevalence of 2.2% (95% CI 1.3% and 3.0%) of the screened population. Age of the AF group was 67 +/- 12 y (range 40-87 y). Using the CHADS2-score, 58% of participants with a positive AF screening had a high risk score, and 21% had an intermediate risk score. Using the CHA2DS2-VASc-score, 72% of the participants had a high risk score, and 21% had an intermediate risk score. CONCLUSION: AF was present in 2.2% of the respondents. At least 60% of AF group had an increased risk for thrombo-embolism. Although substantial methodological issues limit the exact interpretation of these results, the present study shows that a volunatry screening programme with a simple screening protocol is able to detect an important number of patients with previously undetected AF.

Design of a medical record review study on the incidence and preventability of adverse events requiring a higher level of care in Belgian hospitals.

BACKGROUND: Adverse events are unintended patient injuries that arise from healthcare management resulting in disability, prolonged hospital stay or death. Adverse events that require intensive care admission imply a considerable financial burden to the healthcare system. The epidemiology of adverse events in Belgian hospitals has never been assessed systematically. FINDINGS: A multistage retrospective review study of patients requiring a transfer to a higher level of care will be conducted in six hospitals in the province of Limburg. Patient records are reviewed starting from January 2012 by a clinical team consisting of a research nurse, a physician and a clinical pharmacist. Besides the incidence and the level of causation and preventability, also the type of adverse events and their consequences (patient harm, mortality and length of stay) will be assessed. Moreover, the adequacy of the patient records and quality/usefulness of the method of medical record review will be evaluated. DISCUSSION: This paper describes the rationale for a retrospective review study of adverse events that necessitate a higher level of care. More specifically, we are particularly interested in increasing our understanding in the preventability and root causes of these events in order to implement improvement strategies. Attention is paid to the strengths and limitations of the study design.

A nationwide hospital survey on patient safety culture in Belgian hospitals: setting priorities at the launch of a 5-year patient safety plan.

OBJECTIVE: To measure patient safety culture in Belgian hospitals and to examine the homogeneous grouping of underlying safety culture dimensions. METHODS: The Hospital Survey on Patient Safety Culture was distributed organisation-wide in 180 Belgian hospitals participating in the federal program on quality and safety between 2007 and 2009. Participating hospitals were invited to submit their data to a comparative database. Homogeneous groups of underlying safety culture dimensions were sought by hierarchical cluster analysis. RESULTS: 90 acute, 42 psychiatric and 11 long-term care hospitals submitted their data for comparison to other hospitals. The benchmark database included 55 225 completed questionnaires (53.7% response rate). Overall dimensional scores were low, although scores were found to be higher for psychiatric and long-term care hospitals than for acute hospitals. The overall perception of patient safety was lower in French-speaking hospitals. Hierarchical clustering of dimensions resulted in two distinct clusters. Cluster I grouped supervisor/manager expectations and actions promoting safety, organisational learning-continuous improvement, teamwork within units and communication openness, while Cluster II included feedback and communication about error, overall perceptions of patient safety, non-punitive response to error, frequency of events reported, teamwork across units, handoffs and transitions, staffing and management support for patient safety. CONCLUSION: The nationwide safety culture assessment confirms the need for a long-term national initiative to improve patient safety culture and provides each hospital with a baseline patient safety culture profile to direct an intervention plan. The identification of clusters of safety culture dimensions indicates the need for a different approach and context towards the implementation of interventions aimed at improving the safety culture. Certain clusters require unit level improvements, whereas others demand a hospital-wide policy.

Incidence and preventability of adverse events requiring intensive care admission: a systematic review.

RATIONALE, AIMS AND OBJECTIVES: Adverse events are unintended patient injuries or complications that arise from health care management resulting in death, disability or prolonged hospital stay. Adverse events that require critical care are a considerable financial burden to the health care system, but also their global impact on patients and society is probably underestimated. The objectives of this systematic review were to synthesize the best available evidence regarding the estimates of the incidence and preventability of adverse events that necessitate intensive care admission, to determine the type and consequences [mortality, length of intensive care unit (ICU) stay and costs] of these adverse events. METHODS: MEDLINE (from 1966 to present), EMBASE (from 1974 to present) and CENTRAL (version 1-2010) were searched for studies reporting on unplanned admissions on ICUs. Several other sources were searched for additional studies. Only quantitative studies that used chart review for the detection of adverse events requiring intensive care admission were considered for eligibility. For the purposes of this systematic review, ICUs were defined as specialized hospital facilities which provide continuous monitoring and intensive care for acutely ill patients. Studies that were published in the English, Dutch, German, French or Spanish language were eligible for inclusion. Two reviewers independently extracted data and assessed the methodological quality of the included studies. RESULTS: A total of 27 studies were reviewed. Meta-analysis of the data was not appropriate because of methodological and statistical heterogeneity between studies; therefore, results are presented in a descriptive way. The percentage of surgical and medical adverse events that required ICU admission ranged from 1.1% to 37.2%. ICU readmissions varied from 0% to 18.3%. Preventability of the adverse events varied from 17% to 76.5%. Preventable adverse events are further synthesized by type of event. Consequences of the adverse events included a mean length of ICU stay that ranged from 1.5 days to 10.4 days for the patient's first stay in ICU and mortality percentages between 0% and 58%. CONCLUSIONS: Adverse events are an important reason for (re)admission to the ICU and a considerable proportion of these are preventable. It was not possible to estimate an overall incidence and preventability rate of these events as we found considerable heterogeneity. To decrease adverse events that necessitate ICU admission, several systems are recommended such as early detection of patients with clinical instability on general wards and the implementation of rapid response teams. Step-down or intermediate care units could be a useful strategy for patients who require monitoring to avoid ICU readmissions. However, the effectiveness of such systems needs to be investigated.

Challenging patient safety culture: survey results.

PURPOSE: The purpose of this paper is to measure patient safety culture in five Belgian general hospitals. Safety culture plays an important role in the approach towards greater patient safety in hospitals. DESIGN/METHODOLOGY/APPROACH: The Patient Safety Culture Hospital questionnaire was distributed hospital-wide in five general hospitals. It evaluates ten patient safety culture dimensions and two outcomes. The scores were expressed as the percentage of positive answers towards patient safety for each dimension. The survey was conducted from March through November 2005. In total, 3,940 individuals responded (overall response rate = 77 per cent), including 2,813 nurses and assistants, 462 physicians, 397 physiotherapists, laboratory and radiology assistants, social workers and 64 pharmacists and pharmacy assistants. FINDINGS: The dimensional positive scores were found to be low to average in all the hospitals. The lowest scores were "hospital management support for patient safety" (35 per cent), "non-punitive response to error" (36 per cent), "hospital transfers and transitions" (36 per cent), "staffing" (38 per cent), and "teamwork across hospital units" (40 per cent). The dimension "teamwork within hospital units" generated the highest score (70 per cent). Although the same dimensions were considered problematic in the different hospitals, important variations between the five hospitals were observed. PRACTICAL IMPLICATIONS: A comprehensive and tailor-made plan to improve patient safety culture in these hospitals can now be developed. ORIGINALITY/VALUE: Results indicate that important aspects of the patient safety culture in these hospitals need improvement. This is an important challenge to all stakeholders wishing to improve patient safety.

Comparison of albendazole regimen for prophylaxis of strongyloides hyperinfection in nephrotic syndrome patients on long-term steroids in Cambodia.

Nephrotic syndrome patients on long-term steroids face the risk of having heavy uncomplicated strongyloidiasis or death from its extreme form, the strongyloides hyperinfection. The risk can be minimized if we eradicate the parasite first. We compare a once daily and twice daily albendazole regimen in preventing this potentially fatal complication in 122 patients with nephrotic syndrome.
