ABSTRACT

Introduction: According to Lebanese official data, Lebanon hosts over 1.5 million displaced Syrians (DS). Research shows that migrants encounter barriers when accessing healthcare. The social determinants of health (SDOH) related to migration are an additional challenge for DS in Lebanon, though bias plays a significant factor in exacerbating health inequalities. This study aims to identify DS perception of healthcare biases in the Lebanese healthcare system, and its consequences on DS' accessing and receiving quality healthcare in Lebanon. Methods: A qualitative analysis using in-depth, semi-structured interviews was utilized. 28 semi-structured interviews were conducted with doctors (n = 12) and nurses (n = 16) in 2021. Six group interviews were conducted with DS (n = 22) in Lebanese healthcare facilities. The recruitment of participants relied on reasoned and targeted sampling. Thematic analysis was performed to identify common themes in participants' experiences with DS accessing Lebanese healthcare. Results: The findings indicated that there were barriers to accessing healthcare related to the SDOH, such as transportation and financial resources. The results also suggested that DS perceived health biases, including discriminatory behavior from Lebanese healthcare providers, stereotypes and racism leading to health inequalities. Conclusion: Based on the perceptions and experiences reported by participants, the underlying causes of biases are due to the fragility of the Lebanese healthcare system when facing a humanitarian crisis as well as a collapsing infrastructure torn by past wars and the current socio-political and financial crises in the country. Global initiatives are required to provide the necessary resources needed for offering equitable health services. Such initiatives involve addressing biases, health inequities, discrimination, and the lack of a Lebanese infrastructure system for the provision of healthcare. Addressing health inequalities remains a major health objective in achieving health equity on the micro level (cultural awareness and competencies) and macro level (equitable distribution of resources, implementation of a universal health coverage) in order to guarantee quality healthcare services to DS.

ABSTRACT

The study aims to examine cultural differences and discrimination as difficulties encountered by DS when using the Lebanese healthcare system, and to evaluate the equity of DS access to health services in Lebanon. This is a qualitative study using in-depth semi-structured interviews with DS and Lebanese healthcare professionals. The participants were selected by visiting two hospitals, one public Primary Healthcare Center, and three PHCs managed by Non-Governmental Organizations. The recruitment of participants was based on reasoned and targeted sampling. Thematic analysis was performed to identify common themes in participants' experiences of DS in accessing Lebanese healthcare. Twenty interviews took place with directors of health facilities (n = 5), health professionals (n = 9), and DS (n = 6) in six different Lebanese healthcare institutions. The results showed barriers of access to care related to transportation and financial issues. Healthcare services provided to the DS appear to be of poor quality due to inequitable access to the health system, attributable to the discriminatory behavior of healthcare providers. Among the several factors contributing to the presence of discrimination in the Lebanese healthcare system, the persisting fragility of the healthcare system-facing a humanitarian crisis-emerged as the major driver of such unequal treatment. The number of DS in Lebanon is roughly equal to a quarter of its citizens; there is an urging need to restore the Lebanese health system to ensure the equitable provision of health services for DS and appropriate working conditions for health professionals.

ABSTRACT

AIM: There are currently no prospective studies evaluating the long-term outcomes of non-surgical root canal treatments beyond 5 years, both in terms of treatment success and tooth preservation, and identifying factors predictive of treatment outcome. The aim of the present work was therefore to fill this gap by assessing these outcomes over time and identifying predictive variables based on systematic data collection over a 25-year period. METHODOLOGY: Data concerning the treatments (N = 2500) were systematically collected since 1990. Information was recorded among clinical, technical, radiographic and patient-related characteristics, i.e., approximately 150 variables for each treatment. The data were analysed regarding both treatment success and tooth preservation by multivariable Cox proportional hazards model, and survival curves were generated. The statistical significance level was set at 0.0125. RESULTS: In total, 56.4% of the treatments could be followed over time (0-25 years, mean = 6.5 years, median = 5 years). Survival probability decreased almost linearly for treatment success, with about 85% after 5 years and 60% after 20 years, and for tooth preservation, with about 90% at 5 years and 50% at 20 years. The variables significantly associated with treatment failure were: pre-operative pain (Hazard Ratio-HR = 1.56 [95% CI 1.23-1.97]), persistent pain (HR = 2.63 [95% CI 1.44-4.80]), good operator rating of treatment prognosis (HR = 0.46 [95% CI 0.36-0.58]), size of periapical bone radiolucency (HR = 1.88 [95% CI 1.67-2.11]), and tooth type (p = .0006). For tooth extraction, they were: combined endodontic-periodontal lesion (HR = 3.37 [95% CI 1.88-6.05]), pre-existing complication before treatment (HR = 1.67 [95% CI 1.26-2.21]), good operator rating of treatment prognosis (HR = 0.45 [95% CI 0.33-0.60]), clinical failure of root canal treatment (HR = 2.78 [95% CI 1.98-3.89]) and tooth type (p = .0012). CONCLUSION: Root canal treatment success and tooth preservation on the arch are not static outcomes, but evolve with time. Among a substantial set of potential predictors, only a small proportion was significantly predictive of treatment success and tooth preservation, most of them being disease and patient characteristics, and not technical aspects, except pre-existing complications. These observations challenge the importance frequently given to byzantine considerations related to the numerous technical details of endodontic procedures, as opposed to general concepts of good clinical practice.

ABSTRACT

BACKGROUND: Managing older people in the emergency department remains a challenge. We aimed to identify the factors influencing the care quality of older patients in the emergency department, to fine-tune future interventions for older people, considering the naturalistic context of the ED. METHODS: This is a qualitative study of some 450 h of observations performed in three emergency departments selected for their diverse contexts. We performed seventy observations of older patient trajectories admitted to the emergency department. Themes were extracted from the material using an inductive reasoning approach, to highlight factors positively or negatively influencing management of patient's trajectories, in particular those presenting with typically geriatric syndromes. RESULTS: Four themes were developed: no geriatric flow routine; risk of discontinuity of care; unmet basic needs and patient-centered care; complex older patients are unwelcome in EDs. CONCLUSIONS: The overall process of care was based on an organ- and flow-centered paradigm, which ignored older people's specific needs and exposed them to discontinuity of care. Their basic needs were neglected and, when their management slowed the emergency department flow, older people were perceived as unwelcome. Findings of our study can inform the development of interventions about the influence of context and organizational factors.

ABSTRACT

BACKGROUND: Most studies of chronic kidney disease (CKD) in Sub-Saharan Africa (SSA) have been conducted in urban settings. They relied on GFR estimated from serum creatinine alone and on the inexpensive, convenient urinary dipstick to assess proteinuria. The dipstick for proteinuria has not been directly compared with the gold standard albumin-to-creatinine ratio (ACR) in a large-sized study in SSA. We hereby assessed the influence of rural versus urban location on the level, interpretation, and diagnostic performance of proteinuria dipstick versus ACR. METHODS: In a cross-sectional population-based study of CKD in both urban (n = 587) and rural (n = 730) settings in South-Kivu, Democratic Republic of Congo (DRC), we assessed the prevalence, performance (sensitivity, specificity, positive predictive value and negative predictive value) and determinants of a positive dipstick proteinuria as compared with albuminuria (ACR). Albuminuria was subdivided into: A1 (< 30 mg/g creatinine), A2 (30 to 299 mg/g creatinine) and A3 (≥ 300 mg/g creatinine). RESULTS: The overall prevalence of positive dipstick proteinuria (≥ 1+) was 9.6 % (95 % CI, 7.9-11.3) and was higher in rural than in urban residents (13.1 % vs. 4.8 %, p < 0.001), whereas the prevalence of albuminuria (A2 or A3) was similar in both sites (6 % rural vs. 7.6 % urban, p = 0.31). In both sites, dipstick proteinuria ≥ 1 + had a poor sensitivity (< 50 %) and positive predictive value (< 11 %) for the detection of A2 or A3. The negative predictive value was 95 %. Diabetes [aOR 6.12 (1.52-24.53)] was a significant predictor of A3 whereas alkaline [aOR 7.45 (3.28-16.93)] and diluted urine [aOR 2.19 (1.35-3.57)] were the main predictors of positive dipstick proteinuria. CONCLUSIONS: ACR and dipstick proteinuria have similar positivity rates in the urban site whereas, in the rural site, dipstick was 2-fold more often positive than ACR. The poor sensitivity and positive predictive value of the dipstick as compared with ACR makes it unattractive as a screening tool in community studies of CKD in SSA.

ABSTRACT

BACKGROUND: The prevalence of chronic kidney disease (CKD) in African American individuals is high but whether this applies to native populations in sub-Saharan Africa is unclear. METHODS: In a cross-sectional study, we assessed the prevalence and risk factors of CKD in rural and urban adults in South Kivu, Democratic Republic of Congo. Glomerular filtration rate (GFR) was estimated using the CKD-Epidemiology Collaboration (CKD-EPI) equations based on serum creatinine (eGFRcr), cystatin C (eGFRcys), or both markers (eGFRcr-cys), without ethnic correction factor. CKD was defined as an eGFR <60 ml/min per 1.73 m2 and/or albuminuria (albumin-to-creatinine ratio ≥30 mg/g). RESULTS: A total of 1317 participants aged 41.1 ± 17.1 years (730 rural, 587 urban) were enrolled. The prevalence of hypertension (20.2%; 95% confidence interval [CI], 18-22.3), diabetes mellitus (4.3%; 95% CI, 3.2-5.4) and obesity (8.9%; 95% CI, 7.4-10.5) was higher in urban than rural participants (all P < 0.05). HIV infection prevalence was 0.41% (95% CI, 0.05-0.78). The prevalence of eGFRcr <60 ml/min per 1.73 m2 was 5.4% (95% CI, 4.2-6.7). The prevalence of albuminuria was 6.6% (95 % CI, 5.1-8.1). The overall prevalence of CKD was 12.2% (95% CI, 10.2-14.2) according to CKD-EPIcr. Factors independently associated with CKD-EPIcr were older age (adjusted odds ratio [aOR], 1.05 [1.04-1.07]), urban residence (aOR 1.86 [1.18-2.95]), female sex (aOR 1.66 [1.04-2.66]), hypertension (aOR 1.90 [1.15-3.12]), diabetes (aOR 2.03 [1.02-4.06]), and HIV infection (10.21 [2.75-37.85]). The results based on eGFRcys or eGFRcr-cys were largely consistent with the preceding. CONCLUSION: Overall, the burden of CKD is substantial (>11%), predominantly in the urban area, and largely driven by classic risk factors (gender, aging, HIV, hypertension, and diabetes).

ABSTRACT

BACKGROUND: Efficient testing to identify poor quality artemisinin-based combination therapy (ACT) is important to optimize efforts to control and eliminate malaria. Healthcare professionals interact with both ACT and malaria patients they treat and hence could observe, first-hand, suspect poor quality artemisinin-based combinations linked to poor malaria treatment outcomes and the factors associated with inappropriate use or treatment failure. METHODS: A cross-sectional study of 685 HCP perspectives about the efficacy of ACT between June and July 2018 at selected health facilities in Uganda. Medicine samples were obtained from the seven regions of Uganda and tested for quality using the Germany Pharma Health Fund™ minilabs. RESULTS: The average age of the 685 respondents was 30 (SD = 7.4) years. There was an almost equal distribution between male and female respondents (51:49), respectively. Seventy percent (n = 480) were diploma holders and the nurses contributed to half (49%, n = 334) of the study population. Sixty-one percent of the HCPs reported having ever encountered ACT failures while treating uncomplicated malaria. Nineteen percent of HCPs thought that dihydroartemisinin/piperaquine gave the most satisfactory patient treatment outcomes, while 80% HCPs thought that artemether/lumefantrine gave the least satisfactory patient treatment outcomes, possibly due to dosing schedule and pill burden. Healthcare professionals from the Central region (OR = 3.0, CI 0.3-1.0; P = 0.0001), Eastern region (OR = 5.4, CI 2.9-9.8; P = 0.0001) and Northern region (OR = 5.3, CI 2.9-9.9; P = 0.0001) had a higher chance of encountering ACT failure in 4 weeks prior to the survey as compared to those from the western region. Healthcare professionals from private health facilities also had higher chances of encountering ACT failures in past 4 weeks as compared to those from public health facilities (OR = 2.7, CI 1.7-3.9; P = 0.0001). All 192 samples passed the quality screening tests. The random sample of 10% of all samples randomly obtained by the laboratory staff also passed the chemical content analysis and dissolution tests. CONCLUSION: ACT medicines are widely available over-the-counter to the public and it is very difficult to report and monitor a decrease in efficacy or treatment failure. The perspectives of HCPs on treatment failure or lack of efficacy may potentially guide optimization efforts of sampling methodologies for the quality survey of ACT medicines.

ABSTRACT

BACKGROUND: In the Emergency Department (ED), early and rapid identification of older people at risk of adverse outcomes, who could best benefit from complex geriatric intervention, would avoid wasting time, especially in terms of prevention of adverse outcomes, and ensure optimal orientation of vulnerable patients. We wanted to test the predictive ability of a screening tool assessing risk of functional decline (FD), named SHERPA, 10 years after its conception, and to assess the added value of other clinical or biological factors associated with FD. METHODS: A prospective cohort study of older patients (n = 305, ≥ 75 years) admitted through the emergency department, for at least 48 h in non-geriatric wards (mean age 82.5 ± 4.9, 55% women). SHERPA variables (i.e. age, pre-admission instrumental Activity of Daily Living (ADL) status, falls within a year, self-rated health and 21-point MMSE) were collected within 48 h of admission, along with socio-demographic, medical and biological data. Functional status was followed at 3 months by phone. FD was defined as a decrease at 3 months of at least one point in the pre-admission basic ADL score. Predictive ability of SHERPA was assessed using c-statistic, predictive values and likelihood ratios. Measures of discrimination improvement were Net Reclassification Improvement and Integrated Discrimination Improvement. RESULTS: One hundred and five patients (34%) developed 3-month FD. Predictive ability of SHERPA decreased dramatically over 10 years (c = 0.73 vs. 0.64). Only two of its constitutive variables, i.e. falls and instrumental ADL, were significant in logistic regression analysis for functional decline, while 21-point MMSE was kept in the model for clinical relevance. Demographic, comorbidity or laboratory data available upon admission did not improve the SHERPA predictive yield. CONCLUSIONS: Prediction of FD with SHERPA is difficult, but predictive factors, i.e. falls, pre-existing functional limitation and cognitive impairment, stay consistent across time and with literature. As accuracy of SHERPA and others existing screening tools for FD is moderate, using these predictors as flags instead of using composite scales can be a way to screen for high-risk patients.

ABSTRACT

On 20 March 2015, Professor Johan Mackenbach of the Erasmus University Medical Centre was awarded a doctorate honoris causa by the Catholic University (Université Catholique) of Louvain, Belgium, for his outstanding contribution to the analysis of health inequalities in Europe and to the development of policies intended to address them. In this context, a debate took place between Professor Mackenbach, Professor Maniquet, a well-being economist, and a representative of the Federal Health Ministry (Mr. Brieuc Vandamme). They were asked to debate on three topics. (1) socio-economic inequalities in health are not smaller in countries with universal welfare policies; (2) Policies needs to target either absolute inequalities or relative inequalities; (3) The focus of policies should either address the social determinants of health or concentrate on access to health care. The results of the debate by the three speakers highlighted the fact that welfare systems have not been able to tackle diseases of affluence. Targets for health policies should be set according to opportunity cost: health care is increasingly costly and a focus on health inequalities above all other inequalities runs the risk of taking a dogmatic approach to well-being. Health is only one dimension of well-being and policies to address inequality need to balance preferences between several dimensions of well-being. Finally, policymakers may not have that much choice when it comes to reducing inequality: all effective policies should be implemented. For example, Belgium and other European countries should not leave aside health protection policies that are evidence-based, in particular taxes on tobacco and alcohol. In his final contribution, Professor Mackenbach reminded the audience that politics is medicine on a larger scale and stated that policymakers should make more use of research into public health.

ABSTRACT

We studied intraobserver (n = 24), interobserver (n = 24) and interexperiment (n = 12) reproducibility of left ventricular (LV) mass and volume measurements in mice using an 11.7 T MRI system. The LV systolic function was assessed with a short-axis FLASH-cine sequence in 29 mice, including animals having undergone transverse aortic constriction. Bland-Altman and regression analysis were used to compare the different data sets. Reproducibility was excellent for the LV mass and end-diastolic volume (coefficient of variability (CoV) between 5.4 and 11.8 %), good for end-systolic volume (CoV 15.2-19.4 %) and moderate for stroke volume and ejection fraction (CoV 14.7-20.9 %). We found an excellent correlation between LV mass determined by MRI and ex vivo morphometric data (r = 0.92). In conclusion, LV systolic function can be assessed on an 11.7 T MRI scanner with high reproducibility for most parameters, as needed in longitudinal studies. However, data should be interpreted taking into account the moderate reproducibility of small volumes.

ABSTRACT

The chronic care model (CCM) concerns both the medical and the cultural and linguistic needs of patients through the inclusion of cultural competence in the delivery system design. This literature review attempted to@@ identify the domains of the CCM culturally competent (CC) interventions that the adults from ethnic minorities suffering from type 2 diabetes mellitus report. We identified the CCM and the CC components in the relevant studies published between 2005 and 2014. Thirty-two studies were included. Thirty-one articles focused on self-management and 20 on community resources. Twenty-three interventions integrated cultural norms from the patients' backgrounds. CC interventions reported the CCM at the individual level but need to address the organizational level more effectively. The scope of CC interventions should be expanded to transform health care organizations and systems.

ABSTRACT

Demographic changes and healthcare reforms may impact the profile of hospitalized older persons. In this study, we sought to compare the characteristics of two prospective cohorts recruited at a ten-year interval (1999, n=253-2009, n=355). They included older patients (≥75 years) admitted through the emergency department for at least 48 h in acute non-geriatric wards in the same university hospital. The exclusion criteria were patients who were admitted directly to the intensive care unit, who were dependent for all 6 Activities of Daily Living (ADL), who had recently suffered from a major stroke, or whose with a life expectancy of less than 3 months. Median age was higher in 2009 than in 1999 (83 vs. 81; p=0.020), with a higher proportion of those aged 85 years and over (p=0.026). Patients in the 2009 cohort were less likely to live in a nursing home (p=0.018), more dependent for the basic ADL (p<0.001), more independent for the instrumental ADL (p<0.001). They were more likely to have fallen in the previous year (p<0.001). They took more medications (p<0.001). Their length-of-stay was shorter (p<0.001), but they were more likely to be discharged to a rehabilitation center (p<0.001). They underwent more early re-admissions (p=0.020) and similar 3-month functional decline (p=0.614). In conclusion, within a decade, the social, functional and medical characteristics of older patients admitted to hospital have changed significantly. In view of the high consumption of in-patient services by this population, hospitals must adapt to these rapid changes.

ABSTRACT

STUDY OBJECTIVE: Multiple studies have evaluated capnography for the diagnosis of pulmonary embolism; accordingly, we conduct a meta-analysis of these trials. METHODS: We performed a systematic search from 1990 to 2011, using MEDLINE, EMBASE, and the Cochrane Library, including studies evaluating capnography as a diagnostic tool alone or in conjunction with other tests. After study quality evaluation, we calculated the pooled sensitivity, specificity, likelihood ratios, and diagnostic odds ratios. RESULTS: We included 14 trials with 2,291 total subjects, with a 20% overall prevalence of pulmonary embolism. The pooled diagnostic accuracy for capnography was sensitivity 0.80 (95% confidence interval [CI] 0.76 to 0.83), specificity 0.49 (95% CI 0.47 to 0.51), negative likelihood ratio 0.32 (95% CI 0.23 to 0.45), positive likelihood ratio 2.43 (95% CI 1.70 to 3.46), and diagnostic odds ratio 10.4 (95% CI 6.33 to 17.1). The area under the summary receiver operating characteristic curve was 0.84. To reach pulmonary embolism posttest probabilities less than 1%, 2%, or 5%, pulmonary embolism prevalence or pretest probability had to be less than 3%, 5%, or 10% respectively. Because of interstudy differences in dead space measurements methodologies, the best cutoff in alveolar dead space or end tidal CO2 conferring the best negative likelihood ratio could not be evaluated. CONCLUSION: Pooled data suggest a potential diagnostic role for capnography when the pulmonary embolism pretest probability is 10% or less, perhaps after a positive D-dimer test result.

ABSTRACT

BACKGROUND: One young adult in two has entered university education in Western countries. Many of these young students will be exposed, during this transitional period, to substantial changes in living arrangements, socialisation groups, and social activities. This kind of transition is often associated with risky behaviour such as excessive alcohol consumption. So far, however, there is little evidence about the social determinants of alcohol consumption among college students. We set out to explore how college environmental factors shape college students' drinking behaviour. METHODS: In May 2010 a web questionnaire was sent to all bachelor and master students registered with an important Belgian university; 7,015 students participated (participation = 39%). The survey looked at drinking behaviour, social involvement, college environmental factors, drinking norms, and positive drinking consequences. RESULTS: On average each student had 1.7 drinks a day and 2.8 episodes of abusive drinking a month. We found that the more a student was exposed to college environmental factors, the greater the risk of heavy, frequent, and abusive drinking. Alcohol consumption increased for students living on campus, living in a dormitory with a higher number of room-mates, and having been in the University for a long spell. Most such environmental factors were explained by social involvement, such as participation to the student folklore, pre-partying, and normative expectations. CONCLUSIONS: Educational and college authorities need to acknowledge universities' responsibility in relation to their students' drinking behaviour and to commit themselves to support an environment of responsible drinking.

ABSTRACT

BACKGROUND AND AIM OF THE STUDY: The study aim was to define the timing of cerebral embolization events during transcatheter aortic valve implantation (TAVI), and to determine if events were more closely associated with valve implantation or with balloon inflation. METHODS: Between January 2008 and November 2011, a total of 114 patients underwent TAVI at the author's institution. Of these patients, 44 had previously undergone imaging before and after TAVI, and were included in the study (26 transfemoral (TF); 18 transapical (TA)). Eleven patients who had only balloon valvuloplasty (BV) during the same period were included, as were 22 patients who had open aortic valve replacement (AVR), as controls. All 77 patients underwent neurological examination, and all had cerebral MRIs before and after their procedures. RESULTS: Fifty of the 77 patients who underwent postprocedural MRI had new cerebral lesions, as follows: 24/26 (92%) in TF patients; 17/18 (94%) in TA patients; 3/11 (27%) in BV patients; and 6/22 (27%) in AVR patients (TF and TA versus BV and AVR, p < 0.0001). The mean number and volume of embolic lesions per patient were respectively 5.4/438 mm3 for TF, 11.6/3414 mm3 for TA, 0.7/46 mm3 for BV, and 0.4/48 mm3 for AVR (TF versus TA and BV versus AVR, p = NS; TF and TA versus BV and AVR, p < 0.0001). No association was found between either the EuroSCORE or patient age and the number of events. CONCLUSION: In the present study, an incidence of silent cerebral embolic lesions after TAVI was identified which was significantly higher than that for BV or AVR. This indicated an association of embolism with valve implantation rather than with balloon inflation.

ABSTRACT

OBJECTIVES: The spread of drug-eluting stents (DES) has reduced the incidence of early restenosis following percutaneous coronary interventions (PCI). Meanwhile, development of minimally invasive coronary artery bypass surgery (MIDCAB) has offered a valuable alternative to conventional sternotomy with preservation of the benefit of the internal mammary artery use. Therefore, the revascularization of the left anterior descending (LAD) artery is suitable for both techniques. However, few data with long-term comparison of these two techniques exist. METHODS: Prospective data were collected for 456 patients undergoing isolated LAD revascularization between 1997 and 2011. Two hundred and sixty patients were treated with MIDCAB and 196 with first-generation DES implantation. A propensity score model was created to adjust for 19 relevant confounding variables. Primary and secondary end-points were, respectively, 5-year survival and freedom from major adverse cerebro-cardiovascular events (MACCE). RESULTS: Both groups were similar in age, EuroSCORE and mean duration of follow-up. Five-year survival was similar after MIDCAB or DES (hazard ratio (HR): 0.95; P = 0.89). Freedom from MACCE was significantly in favour of the MIDCAB group (HR: 0.32, P < 0.0001), mainly triggered by high subsequent need for revascularization of the targeted vessel in the DES group (HR: 0.17, P < 0.0001). CONCLUSIONS: MIDCAB and DES implantation showed similar rates of survival but despite an expected lower rate of reintervention on the targeted vessel with DES use, a highly significant higher MACCE rate was observed in the PCI group at 5-year follow-up.

ABSTRACT

AIM: To report a study exploring prospective relations between nurses' perceived work ability and three forms of turnover intentions, respectively, intent to leave the ward, organization and profession. BACKGROUND: Turnover of nursing staff is a major challenge for healthcare settings and for healthcare in general, urging the need to improve retention. DESIGN: Survey. METHODS: Based on the longitudinal data of the Belgian sample from the European Nurses' Early Exit study, a total of 1531 healthcare workers who remained in their job, completed in 2003 and 1 year later a self-administered questionnaire including the Work Ability Index to assess work ability. Multiple logistic regression analysis was performed adjusting for possible confounding variables. RESULTS: In a population with low intent to leave at baseline prospective analyses showed that a poor work ability at baseline increased the risk of high intent to leave the ward and high intent to leave the organization, 1 year later. A substantial deterioration in work ability was a risk factor for developing high turnover intentions 1 year later. Social support had no effect on the relation between work ability and all three types of intent to leave but the relation between work ability and intent to leave the ward was borderline significantly moderated by good interpersonal relations. CONCLUSIONS: Poor work ability was a risk factor for developing turnover intentions. Maintaining good work ability and improving poor work ability becomes increasingly important to retain nurses.

ABSTRACT

OBJECTIVES: The long-term advantages of multiple arterial grafts, particularly a third arterial conduit, for coronary artery bypass (CABG) are not clear. This study was designed to test whether multiple arterial grafts would provide better long-term outcomes when compared with approaches using fewer arterial conduits. METHODS: Between 1985 and 1995, prospective data were collected for 588 patients undergoing isolated CABG at our institution. We examined long-term survival and freedom from cardiac death. The primary analysis compared patients receiving bilateral internal thoracic artery (BITA) vs. single ITA (SITA). In a subgroup analysis, BITA patients receiving a right gastroepiploic artery (RGEA) were compared with those receiving a saphenous vein graft (SVG) as a third conduit. Cox proportional hazard modelling was used to adjust for relevant confounders. The Kaplan-Meier method was used to create survival curves over the follow-up period. RESULTS: The mean age was 59 ± 9 years and 49% received BITA. Mean follow-up was 16.1 ± 5.4 years. Multivariable analysis revealed that overall survival [hazard ratio (HR): 0.74, P = 0.017] and cardiac survival (HR: 0.61, P = 0.004) was significantly improved in the presence of BITA compared with SITA. The survival at 10 and 20 years was 90.2 ± 3.4 and 56.9 ± 6.4% for the BITA vs. 82 ± 4.4 and 40.9 ± 6% for the SITA, respectively. In the subgroup of BITA patients, those receiving the RGEA as a third conduit had superior overall survival (HR: 0.41, P = 0.0032) and cardiac survival (HR: 0.18, P = 0.004) compared with those receiving an SVG. The survival at 10 and 20 years was 98.9 ± 2 and 68.9 ± 18% for the BITA/RGEA vs. 87.2 ± 4.6 and 50.3 ± 7% for the BITA/SVG, respectively. CONCLUSIONS: In a single-institution experience, the use of multiple arterial grafting is independently associated with superior outcomes. Furthermore, the use of a third arterial conduit (RGEA) targeted to the right coronary artery should be considered to improve long-term survival.

ABSTRACT

OBJECTIVE: Saphenous vein, in situ right gastroepiploic artery, and right internal thoracic artery grafts are routinely used to revascularize the right coronary artery. Little is known about the predictive value of objective preoperative angiographic parameters on midterm graft patency. METHODS: We prospectively enrolled 210 consecutive patients undergoing coronary revascularization. Revascularization of the right coronary artery was randomly performed with the saphenous vein grafts in 81 patients and the right gastroepiploic artery in 92 patients. During the same study period, 37 patients received right coronary artery revascularization with the right internal thoracic artery used in a Y-composite fashion. All patients underwent a protocol-driven coronary angiogram 3 years after surgery. Preoperative angiographic parameters included minimum lumen diameter percent stenosis measured by quantitative angiography. A graft was considered "not functional" with patency scores of 0 to 2 and "functional" with patency scores of 3 or 4. RESULTS: Angiographic follow-up was 100% complete. A significant difference in the distribution of flow patterns was observed in the 3 groups. In multivariate analysis, the use of a saphenous vein graft was associated with superior graft functionality compared with the other conduits (odds ratio, 6.1; 95% confidence interval, 2.4-15). Graft function was negatively influenced by the minimum lumen diameter (odds ratio, 0.11; confidence interval, 0.05-0.25). In the right gastroepiploic artery and right internal thoracic artery groups, the proportion of functional grafts was higher when the minimum lumen diameter was below a threshold value in the third minimum lumen diameter quartile (0.64-1.30 mm). CONCLUSIONS: Preoperative angiography predicts graft patency in the right gastroepiploic artery and right internal thoracic artery, whereas the flow pattern in saphenous vein grafts is significantly less influenced by quantitative angiographic parameters.

ABSTRACT

BACKGROUND: Despite being a key player in the healthcare system, training and practising general practice has become less attractive in many countries and is in need of reform. AIM: To identify political priorities for improving GPs' attraction to the profession and their retention within it. DESIGN AND SETTING: Stakeholder face-to-face survey in Belgium, 2008. METHOD: A total of 102 key stakeholders were recruited from policymakers, professional groups, academia, GP leaders, and the media. All interviewees were asked to score 23 policies on four criteria: effectiveness in attracting and retaining GPs, cost to society, acceptance by other health professionals, and accessibility of care. An overall performance score was computed (from -3 to +3) for each type of policy - training, financing, work-life balance, practice organisation, and governance - and for innovative versus conservative policies. RESULTS: Practice organisation policies and training policies received the highest scores (mean score ≥ 1.11). Financing policies, governance, and work-life balance policies scored poorly (mean score ≤ 0.65) because they had negative effects, particularly in relation to cost, acceptance, and accessibility of care. Stakeholders were keen on moving GPs towards team work, improving their role as care coordinator, and helping them to offload administrative tasks (score ≥ 1.4). They also favoured moves to increase the early and integrated exposure of all medical students to general practice. Overall, conservative policies were better scored than innovative ones (beta = -0.16, 95% confidence interval = -0.28 to -0.03). CONCLUSION: The reforming of general practice is made difficult by the small-step approach, as well as the importance of decision criteria related to cost, acceptance, and access.
