ABSTRACT
Workers at scientific academic laboratories are at risk of potential exposure to different types of hazards. The study's purpose was to assess the potential failure modes (FMs) of hazards facing them through the application of the Failure Mode and Effect Analysis (FMEA) method to propose corrective actions preventive actions (CAPA) to mitigate them and to improve the safety outcomes in these workplaces (WP) at the Lebanese public University (PbU). The potential FMs leading to accident occurrence in biological and chemical labs were identified and prioritized, their causes and effects were determined by applying two surveys, and the risk priority number (RPN) for each failure was calculated. A total of 24 FMs were identified. The most alarming FM having the highest RPN scores (80) was found in the workplace 'category requiring an emergency for corrective actions (CA), it is related to the unavailability of a hazard pictogram plot and the lack of labeling of chemicals and waste containers according to their categories. The FMs having RPN scores (75-60) requiring an urgent CA were assigned to other hazards of the WP, chemical, biological, and failure of the educational system. The need to program for the remaining FMs (RPN scores 20-48) is related to the safety, biological, physical, and radioactive categories 'hazards. It is recommended to apply continuously FMEA and implement the CA proposed for each detected FM in the scientific laboratories of the PbU in order to support the decision-makers to improve laboratory safety.
ABSTRACT
Background: Workers are exposed to several risks in academic laboratories due to the presence of potentially hazardous substances. The main objective of this study was to assess the prevalence of accident occurrence and associated risk factors among laboratory workers at the scientific laboratories of the public university in Lebanon and the impact of safety measures training and availability. Methods: In this observational study, a survey was conducted for one year in scientific laboratories at faculties of the public university. Results: Among the participants (N = 220), 45.0% have had accidents; the main cause was exposure to chemicals (73.7%) and more specifically by inhalation (45.4%). Females (85.9%) were more exposed to accidents than males. Laboratory workers with a master's degree, a full-time schedule, and more than ten years of experience were significantly more exposed to accidents (p < 0.05). A significant association was found between accident occurrence and training on management of hazardous products (p = 0.044), risks related to workplace (p = 0.030), eyewash and emergency shower (p < 0.001), first aid (p = 0.012), and facial protection availability (p = 0.019). In spite of the lack of safety culture and efficient training on laboratory safety, participants have shown a very good perception regarding safety measures to be applied in case of work accidents. Conclusion: Based on our findings, the prevalence of accident occurrence is elevated among lab workers at the public university. The impact of regular training on laboratory safety preventive measures is of great importance to ensure the efficiency of occupational health and safety in scientific laboratories.
ABSTRACT
Controlling hypertension is essential in cardiovascular diseases. Poor medication adherence is associated with poor disease outcomes, waste of healthcare resources, and contributes to reduced blood pressure control. This study evaluates treatment adherence to antihypertensive therapy in Lebanese hypertensive patients by estimating the proportion of adherent hypertensive patients using a validated tool and investigates what factors predict this behavior. A questionnaire-based cross-sectional study was conducted on a random sample of 210 hypertensive outpatients selected from clinics located in tertiary-care hospitals and from private cardiology clinics located in Beirut. Adherence level was measured using a validated 8-item Modified Morisky Medication Adherence Scale (MMMAS). Among 210 patients, 50.5% showed high adherence, 27.1% medium adherence, and 22.4% low adherence to medication. Mean MMMAS score was 6.59±2.0. In bivariate analyses, having controlled blood pressure (p=0.003) and taking a combination drug (p=0.023) were predictors of high adherence. Forgetfulness (p<0.01), complicated drug regimen (p=0.001), and side effects (p=0.006) were predictors of low adherence after multiple liner regression. Logistic regression results showed that calcium channel blockers (p=0.030) were associated with increased adherence levels. In conclusion, developing multidisciplinary intervention programs to address the factors identified, in addition to educational strategies targeting healthcare providers, are necessary to enhance patient adherence.

Cardiovascular disease is a major cause of morbidity and mortality worldwide, hypertension being one of their most prevalent risk factors. Information on health related quality of life (QOL) of hypertensive individuals in Lebanon is lacking. Our objectives were to evaluate QOL of hypertensive patients compared with non-hypertensive subjects and to suggest possible predictors of QOL in Lebanon. We conducted a case control study among individuals visiting outpatient clinics. Quality of life was assessed using the eight item (SF-8) questionnaire administered face to face to the study population, applied to hypertensive (N=224) and non-hypertensive control (N=448) groups. Hypertensive patients presented lower QOL scores in all domains, particularly in case of high administration frequency and occurrence of drug related side effects. Among hypertensive patients, QOL was significantly decreased with the presence of comorbidities (ß=-13.865, p=0.054), daily frequency of antihypertensive medications (ß=-8.196, p<0.001), presence of drug side-effects (ß=-19.262, p=0.031), older age (ß=-0.548, p<0.001), female gender (ß=-21.363, p=0.05), lower education (ß=-22.949, p=0.006), and cigarettes smoked daily (ß=-0.726, p<0.001); regular sport activity (ß=23.15, p<0.001) significantly increased quality of life. These findings indicate the necessity for health professionals to take these factors into account when treating hypertensive patients, and to tackle special subgroups with attention to their deteriorated QOL.

BACKGROUND: Non-adherence to prescribed medications represents an obstacle toward achieving treatment goals. This problem is more pronounced in patients with chronic illness. OBJECTIVE: To identify the extent of adherence in Lebanese outpatients with chronic diseases, and to suggest possible predictors of non-adherence in this population. The secondary objective was to assess if medication adherence affects patients' quality of life. METHODS: A questionnaire was administered face-to-face to a sample of Lebanese adults visiting the external clinics at two Tertiary Care Hospitals in Beirut. The level of adherence was assessed using the 8-item Morisky Medication Adherence Scale which was first validated. The health-related quality of life (HRQoL) of patients was measured using the EQ-5D. Linear regression and logistic regression analyses examined possible predictors of adherence. RESULTS: Out of the 148 patients included in this study, 42.6% were classified as adherent. In the univariate analyses, statistically significant predictors of high adherence included good physician-patient relationship (p=0.029) and counseling (p=0.037), a high level of HRQoL (p<0.001), and a high level of perceived health (p<0.001). Predictors of low adherence included a declining memory (p<0.001), anxiety/depression (p=0.002), little drug knowledge (p<0.001), and postponing physician appointments (p<0.001). The multivariate analyses revealed similar results. In the linear regression, the most powerful predictor of non-adherence was the disbelief that the drug is ameliorating the disease (beta=0.279), however, in logistic regression, patient who were willing to skip or double doses in case of amelioration/deterioration were found to be 7.35 times more likely to be non-adherent than those who were not (aOR=0.136, 95% CI: 0.037-0.503). CONCLUSION: The findings of this study reassure the view that patients should be regarded as active decision makers. Patient education should be regarded as a cornerstone for treatment success. Additional studies as well are needed to test the practicability and effectiveness of interventions suggested to enhance adherence.
ABSTRACT
BACKGROUND: Hip fractures are serious fall injuries that often result in long-term functional impairment and increased mortality. As the population ages, the number of hip fractures is likely to increase worldwide. The main objective of this pilot study was to evaluate the risk factors of hip fracture among the older adults in the Lebanese population. METHODS: This pilot epidemiological, prospective, and case-control study was performed in 6 hospitals in Great Beirut and South Lebanon. Subjects who met the inclusion criteria filled out a questionnaire consisting on the socio- demographic characteristics, health status, drugs intake and cigarette smoking. RESULTS: Overall, 195 subjects were recruited, with 65 cases of hip fracture and 130 controls all aged over 50 yr. Females represented around two third of the studied population. The logistic regression, using adjusted odds ratio (ORa), showed a significant relationship between hip fracture and chronic diseases (ORa=3.02; 95% CI: 1.63, 6.66), antihypertensive drugs intake (ORa=2.72; 95% CI: 1.56, 6.42), fall (ORa=2.79; 95% CI: 1.82, 7.06) previous fracture (ORa=3.80; 95% CI: 1.57, 9.23) and family history of fracture (ORa=4.82; 95% CI: (2.29, 10.86). Besides, smoking increased the risk of hip fracture (ORa=2.55; 95% CI: (1.96, 5.80). Having a bow was associated with the highest risk for hip fracture (ORa=5.18; 95% CI: 2.30, 12.24). CONCLUSIONS: Elderly people in Lebanon are exposed to many risk factors contributing to hip fracture. Our finding has implication in geriatric health improvement by preventing hip fracture in the Lebanese population.

Antecedentes: La no adherencia a la medicación prescrita representa un obstáculo hacia la consecución de los objetivos terapéuticos. Este problema es más grave en pacientes con enfermedades crónicas. Objetivo: Identificar la proporción de adherencia en los pacientes ambulatorios libaneses con enfermedades crónicas y sugerir posibles predictores de adherencia en esta población. El objetivo secundario fue evaluar si la adherencia a la medicación afecta a la calidad de vida de los pacientes. Métodos: Se administró presencialmente un cuestionario a una muestra de adultos libaneses que visitan las consultas ambulatorias de dos hospitales terciarios de Beirut. El nivel de adherencia se midió usando la Morisky Medication Adherence Scale de 8 ítems, que fue primeramente validada. La calidad de vida relacionada con la salud (HRQoL) de los pacientes se midió usando el EQ-5D. Análisis de regresión lineal y regresión logística examinaron los posibles predictores de adherencia. Resultados: De los 148 pacientes incluidos en este estudio, el 42,6% fueron clasificados como adherentes. En el análisis univariado, entre los predictores estadísticamente significativos se incluían la buena relación paciente-médico (p=0,029) y el asesoramiento (p=0,037), un elevado nivel de HRQoL (p<0,001), y un elevado nivel de salud percibida (p<0,001). Los predictores de baja adherencia incluían el descenso de la memoria (p=0,002), bajo conocimiento de los medicamentos (p<0,001), y posponer las citas con el médico (p<0,001). El análisis multivariado reveló resultados similares. En la regresión lineal, el predictor más potente de no adherencia fue la falta de confianza en que el medicamento mejoraba la enfermedad (beta=0,279), sin embargo en la regresión logística, los pacientes que estaban dispuestos a doblar o saltarse la dosis en caso de mejora/empeoramiento aparecieron con 7,35 veces más probabilidad de ser no adherentes que los otros (ORa=0,136, 95%CI: 0,037-0,503). Conclusión: Los hallazgos de este estudio refuerzan el hecho de que los pacientes deben ser considerados como decisores activos. La educación de los pacientes debería ser considerada como un elemento clave del éxito del tratamiento. Deben realizarse estudios para probar la efectividad y práctica de las intervenciones propuestas para mejorar la adherencia (AU)
