Depression, Stress and the Mediating Role of Intimate Partner Violence (IPV) Among Israeli Women of Childbearing Age in the Shadow of the COVID-19 Pandemic.

Dealing with the outbreak of the new coronavirus has generated unprecedented challenges around the world, including in Israel. Women of childbearing age may be forced to live under particularly difficult circumstances during the pandemic. The current study among Israeli women of childbearing age has three main objectives related to the specific period of the COVID-19 pandemic: to study the prevalence and predictors of intimate partner violence (IPV); to investigate the prevalence and predictors of depression; to examine whether IPV mediates the association between general stress, fear of COVID-19 and depression as an outcome. In a cross-sectional study, 722 married women, Jewish and Arab residents of Israel, were recruited to answer an online self-completion questionnaire during the first wave of the COVID-19 pandemic. The questionnaire included an assessment of their degree of general stress and depression, fear of COVID-19, experiences of IPV and demographic variables. The results of the current study show that a high percentage of women reported IPV (with Muslim women reporting higher IPV than Jewish women), perceived stress (PSS), perceived COVID-19 stress and depression. The findings also show that IPV and its three dimensions mediate the relationship between COVID-19 stress and depression, such that higher stress was related to higher IPV, raising the odds for depression. Moreover, the total scores for IPV and emotional violence were found to mediate the relationship between stress and depression. That is, domestic violence explains part of the association between stress and depression during the COVID-19 pandemic. Indeed, the current pandemic has resulted in an increase in IPV and depression, and especially in the specific stress associated with the disease itself. Based on the findings of the current study, preventing violence will reduce stress-related depression. The Muslim population, and especially those who are more religious, is in particular need of intervention.

Effects of rich cannabidiol oil on behavioral disturbances in patients with dementia: A placebo controlled randomized clinical trial.

Background: Almost 90% of patients with dementia suffer from some type of neurobehavioral symptom, and there are no approved medications to address these symptoms. Objective: To evaluate the safety and efficacy of the medical cannabis oil "Avidekel" for the reduction of behavioral disturbances among patients with dementia. Materials and methods: In this randomized, double-blind, single-cite, placebo-controlled trial conducted in Israel (ClinicalTrials.gov: NCT03328676), patients aged at least 60, with a diagnosis of major neurocognitive disorder and associated behavioral disturbances were randomized 2:1 to receive either "Avidekel," a broad-spectrum cannabis oil (30% cannabidiol and 1% tetrahydrocannabinol: 295 mg and 12.5 mg per ml, respectively; n = 40) or a placebo oil (n = 20) three times a day for 16 weeks. The primary outcome was a decrease, as compared to baseline, of four or more points on the Cohen-Mansfield Agitation Inventory score by week 16. Results: From 60 randomized patients [mean age, 79.4 years; 36 women (60.0%)], 52 (86.7%) completed the trial (all eight patients who discontinued treatment were from the investigational group). There was a statistically significant difference in the proportion of subjects who had a Cohen-Mansfield Agitation Inventory score reduction of ≥ 4 points at week 16: 24/40 (60.0%) and 6/20 (30.0%) for investigational and control groups, respectively (χ2 = 4.80, P = 0.03). There was a statistically significant difference in the proportion of subjects who had a Cohen-Mansfield Agitation Inventory score reduction of ≥ 8 points at week 16: 20/40 (50%) and 3/20 (15%), respectively (χ2 = 6.42, P = 0.011). The ANOVA repeated measures analysis demonstrated significantly more improvement in the investigational group compared to the control group at weeks 14 and 16 (F = 3.18, P = 0.02). Treatment was mostly safe, with no significant differences in the occurrence of adverse events between the two groups. Conclusion: In this randomized controlled trial, 'Avidekel' oil significantly reduced agitation over placebo in patients suffering from behavioral disturbances related to dementia, with non-serious side-effects. Further research is required with a larger sample size.

A unique program for nursing students to enhance their mentalization capabilities in relation to clinical thinking.

While nurses strive to provide optimal patient-centered care, this is not always straightforward, as some cases are more emotionally charged than others - depending on the patient's mental, emotional, and physical state, and on the nurses themselves. Therefore, in order to provide accurate therapeutic responses while maintaining their own personal well-being, nurses must develop strong mentalization capabilities. We present a unique program for nursing students, specifically targeted at enhancing their mentalization abilities as part of their communication skills for dealing with emotionally charged situations. In the program, he students first learn to identify what leads them to experience increased emotional loads and how this affects their mentalization processes. Next, they learn alternative coping patterns for their benefit, enabling their own emotional regulation while providing optimal care for their patients. Conducted in small groups, this holistic four-year program is led by experienced clinical nurses and psychologists; the learning is based on actual experiences encountered by the students during their clinical experience.

Factors influencing prevalence of vision and ocular abnormalities among Jewish and Arab Israeli schoolchildren.

BACKGROUND: The detection and correction of refractive errors is one of the priorities of the World Health Organization Initiative Vision 2020. OBJECTIVES: To determine the factors related to ocular abnormalities (poor vision, refractive error or other abnormality) among schoolchildren in northern Israel. METHODS: A cross-sectional population-based study was conducted among 2113 students aged 6-7 and 13-14 years old in 70 schools in northern Israel. Medical examination included vision history, clinical eye examination and vision testing. If a parent's informed consent was available, eye drops (cycloplegia) were delivered for fundus and retinoscopy testing. An ophthalmologist was asked to determine the need for the child's referral for further diagnostic procedures, treatment and/or follow-up. Multivariate analysis was limited to 1708 children, using data pertaining to the ophthalmologist's decision regarding referral, as well as vision and retinoscopy results. RESULTS: Vision and/or ocular abnormality was prevalent in 21.5% (95% confidence interval 17.4-26.6%), predominantly among 13-14 year olds and Jewish children. Abnormal clinical findings were found in 5.7% of the students. Retinoscopy showed a higher prevalence of hypermetropia among 6-7 year olds and a higher prevalence of myopia and astigmatism among the 13-14 year olds. The multivariate analysis suggests an independent effect of retinoscopy abnormality (odds ratio = 3.85), vision abnormality (OR = 2.42), Jewish ethnicity (OR = 1.62) and 13-14 year old age group (OR = 1.26) on the ophthalmologist's referral decision. CONCLUSIONS: Vision and/or ocular abnormality is an important health problem among schoolchildren in northern Israel. The independent effect of ethnicity and age on the ophthalmologist's referral decision should be further explored.

[Compliance with latent tuberculosis treatment: a public health challenge].

Tuberculosis (TB) is a major infectious cause of morbidity and mortality, mainly in developing countries. Since the incidence of TB has decreased in the developed countries, the role of diagnosis and treatment of latent TB infection (LTBI), has assumed increasing importance as a public health measure to control TB. It is estimated that 5-10% of persons with LTBI go on to develop TB; therefore, the crucial role of LTBI treatment in eliminating TB is well recognized. However, levels of adherence to treatment of LTBI are consistently low, and non-compliance constitutes the major barrier for achieving the full benefits of LTBI treatment, emphasizing the pressing need to implement compliance-enhancing interventions. We present a review of studies in which various interventions aimed at enhancing LTBI treatment adherence were applied.

Does Pomegranate intake attenuate cardiovascular risk factors in hemodialysis patients?

BACKGROUND: Atherosclerotic cardiovascular disease (CVD) is the most common cause of morbidity and mortality among hemodialysis (HD) patients. It has been attributed, among other causes, to hypertension and dyslipidemia. The aim of the present study was to investigate the effect of a year-long consumption of Pomegranate juice (PJ), on two traditional cardiovascular (CV) risk factors: hypertension and lipid profile, as well as on cardiovascular events. METHODS: 101 HD patients were randomized to receive 100 cc of PJ (0.7 mM polyphenols) or matching placebo juice, three times a week for one year. The primary endpoints were traditional CV risk factors; blood pressure and lipid profile. Systolic, diastolic and pulse pressure, plasma levels of triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and total cholesterol were monitored quarterly during the study year. Secondary endpoint was incidence of cardiovascular events. RESULTS: PJ consumption yielded a significant time response improvement in systolic blood pressure, pulse pressure, triglycerides and HDL level; an improvement that was not observed in the placebo intake group. These beneficial outcomes were more pronounced among patients with hypertension, high level of triglycerides and low levels of HDL. CONCLUSION: Regular PJ consumption by HD patients reduced systolic blood pressure and improved lipid profile. These favorable changes may reduce the accelerated atherosclerosis and high incidence of CVD among HD patients. TRIAL REGISTRATION: ClinicalTrials.gov registry, Identifier number: NCT00727519.

[Accessibility and compliance of Ethiopian immigrants to latent tuberculosis infection treatment].

BACKGROUND: Since the incidence of TB has decreased in the developed countries, the diagnosis and treatment of latent TB infection (LTBI) has assumed increasing importance. It is estimated that 5-10% of persons with LTBI go on to develop TB; therefore, the crucial role of LTBI treatment in eliminating TB is well recognized. However, levels of adherence are found to be consistently low, and noncompliance constitutes the major barrier for achieving the full benefits of LTBI treatment. OBJECTIVE: 1. To estimate rates of treatment completion with an outreach - directly observed preventive treatment (DOPT), a program among Ethiopian immigrants (El) at absorption centers treated for LTBI. 2. To determine if follow-up visits by a physician at their place of residence, vs. management at a TB Clinic (TBC), would further enhance the patient's adherence. METHODOLOGY: Quasi experiment, retrospective cohort analysis of 495 medical records for all El at absorption centers in Zefat who had started DOPT for LTBI and were followed up at absorption centers (2005-2006, study group - SG), compared to patients followed up at a TBC (2008-2010, comparison group - CG). Free transportation to the TBC was provided for the CG. FINDINGS: Altogether 495 Els were included (263 in the SG and 232 in the CG group). Both groups had high completion rates (SG: 96.2% vs. CG: 93.1%, p=0.14). While demographic factors did not predict treatment completion, side effects were significantly associated with non-completion. CONCLUSION: High treatment completion rates among El were achieved when DOPT outreach and cultural case management strategies were combined. In these circumstances, the physician follow-up location had no significant impact on treatment completion rates.

Pomegranate juice intake attenuates the increase in oxidative stress induced by intravenous iron during hemodialysis.

The hemodialysis (HD) procedure induces oxidative stress (OS), which is further aggravated by intravenous (IV) iron administration, aimed at correcting anemia of patients with HD. We have recently shown that 1 year of pomegranate juice (PJ) intake attenuated OS and inflammation in patients with HD. In the current study, we hypothesized that a single dose of PJ can attenuate the enhanced OS and inflammation induced by both the dialysis procedure and IV iron administration during HD session. Twenty-seven patients with HD were randomized to receive PJ or placebo during 1 dialysis session with IV iron. Blood samples were drawn before and after the session to asses OS biomarkers such as advanced oxidation protein products and myeloperoxidase (MPO), whereas polymorphonuclear leukocyte (PMNL) counts served as an indirect measure of inflammation. At the end of the dialysis session, an increase in advanced oxidation protein products and MPO levels as well as a decrease in PMNLs counts were observed in the placebo group, whereas no significant changes occurred in the PJ group. The postdialysis increase in MPO levels in the placebo group is a direct result of PMNL degranulation, associated with postdialysis decrease in PMNL counts. Degranulation of PMNLs leads to the release of other cell moieties, such as inflammatory mediators and proteases that enhance inflammation. We conclude that PJ intake attenuated the increase in systemic OS and inflammation induced by IV iron administration during the dialysis session. These beneficial effects illuminate the previously observed attenuation in OS and inflammation in patients with HD on prolonged PJ intake.

Prognostic factors predicting ischemic wound healing following hyperbaric oxygenation therapy.

Identifying patients who benefit from hyperoxygenation therapy is important, because treatment is time-consuming and involves high costs and complications (minor). Our objective was to develop a model for predicting therapy outcome based on population of patients with and without diabetes. A retrospective cohort study was carried out in a major hospital in Israel. All 385 patients treated between 1/1/1998 and 1/1/2007 for ischemic nonhealing lower extremities wounds were included. Data on medical history, demographic, transcutaneous oximetry, wounds, treatment, and outcome characteristics were collected. Eight factors were identified to optimally predict wound healing: (1) number of hyperbaric oxygenation treatments (odds ratio [OR] = 1.034, p < 0.001), (2) transcutaneous oximetry values at hyperbaric conditions (OR = 1.001, p = 0.019), (3) wound duration (OR = 0.988, p = 0.022), (4) absence of heart disease (OR = 3.304, p < 0.001), (5) being employed (OR = 3.16, p = 0.008), (6) low socioeconomic status (OR = 2.50, p = 0.004), (7a) good/partial granulation wound appearance (OR = 2.73, p = 0.022), (7b) wounds covered with fibrin (OR = 3.16, p = 0.015), and (8) absence of anemia (OR = 2.13, p = 0.016). The model's sensitivity is 78.7%, specificity is 62.9%, and accuracy is 71.8%. We suggest using our model as an adjunct to patients' clinical evaluation. Also, we recommend initiating hyperoxygenation therapy no later than 2 months after wound appearance.

Factors associated with iatrogenesis in neonatal intensive care units: an observational multicenter study.

The objective of our study was to assess factors associated with iatrogenic events in Neonatal Intensive Care Units (NICUs). This was a retrospective analysis based on a cohort of patients who participated in our previous prospective study (Pediatrics 122:550-555, 2008), conducted in four tertiary university-affiliated NICUs in Israel, that included all consecutive infants (n = 615) hospitalized during the study period. Ongoing monitoring of iatrogenic events was performed by designated "iatrogenesis advocates." The main outcome measures were the association of individual infant characteristics and NICUs' environmental characteristics with iatrogenic events assessed by univariate and multiple logistic regression analysis. We found that four infant characteristics were significantly (p < 0.001) associated with iatrogenic events in a univariate analysis: gestational age, birth weight, severity of initial illness as assessed by the Score for Neonatal Acute Physiology and Perinatal Extension (SNAPPE II), and length of stay (LOS). All four factors demonstrated a significant (p < 0.001) dose-response relationship with iatrogenic events. Univariate analysis for environmental characteristics showed that type of shift, but not nursing workload, was significantly associated with iatrogenic events (p < 0.001). In a multiple logistic regression analysis, only LOS (adjusted OR 1.02 [95 % CI, 1.01-1.03]) and type of shift, morning vs. evening (adjusted OR 3.44 [95 % CI, 2.33-5.08]) and morning vs. night (adjusted OR 6.07 [95 % CI, 3.86-9.56]), remained independently associated with iatrogenic events (p < 0.001). Prolonged LOS and morning shifts were found to be significantly associated with iatrogenic events. Further prospective research is warranted to identify the specific causes for iatrogenic events in order to target active interventions to prevent them.

One year of pomegranate juice intake decreases oxidative stress, inflammation, and incidence of infections in hemodialysis patients: a randomized placebo-controlled trial.

Increased systemic inflammation and oxidative stress are well established as nontraditional key players in the pathogenesis of atherosclerosis and are also involved in the innate immunity dysregulation in hemodialysis (HD) patients. The study aim was to investigate the effect of 1-year intake of pomegranate juice, an antioxidant source, on oxidative stress, inflammation, and long-term clinical outcomes. A randomized placebo controlled double-blind trial was designed, enrolling 101 chronic HD patients to receive during each dialysis 100 cc of pomegranate juice, or matching placebo, three times a week for 1 year. The primary endpoints were levels of oxidative stress and inflammation biomarkers. Secondary endpoints were hospitalization due to infections and the progression of atherosclerotic process based on a composite of variables of the carotid arteries: intima media thickness (IMT), number, and structure of plaques. Pomegranate juice intake yielded a significant time response reduction in polymorphonuclear leukocyte priming, protein oxidation, lipid oxidation, and inflammation biomarkers levels. These beneficial effects were abolished 3 months postintervention. Pomegranate juice intake resulted in a significantly lower incidence rate of the second hospitalization due to infections. Furthermore, 25% of the patients in the pomegranate juice group had improvement and only 5% progression in the atherosclerotic process, while more than 50% of patients in the placebo group showed progression and none showed any improvement. Prolonged pomegranate juice intake improves nontraditional CV risk factors, attenuates the progression of the atherosclerotic process, strengthens the innate immunity, and thus reduces morbidity among HD patients.

Improvement of ischemic non-healing wounds following hyperoxygenation: the experience at Rambam-Elisha Hyperbaric Center in Israel, 1998-2007.

BACKGROUND: Wounds of the lower extremities are a significant public health problem, being severe and costly to treat. Adjunctive treatment with hyperbaric oxygenation (HBOT) has proven to be a useful and cost-effective means of treating ischemic wounds, mainly in diabetic patients. OBJECTIVES: To describe patients with ischemic wounds treated at the Rambam and Elisha Hyperbaric Medical Center and their wound improvement following HBOT. METHODS: We conducted a retrospective cohort study of all patients (N = 385) treated in the center during 1998-2007 for ischemic non-healing wounds in the lower extremities. RESULTS: The mean age of the patients was 61.9 years (SD 13.97). Most of them were diabetic (69.6%) and male (68.8%). Half of the subjects had a wound for more than 3 months prior to undergoing pre-HBOT transcutaneous oximetry (TcPO2) testing. Most of the wounds were classified as Wagner degree 1 or 2 (39.1% and 46.2% respectively). The median number of treatments per patient was 29. Only 63.1% of patients had continuous treatments. Approximately 20% of patients experienced mild side effects. An improvement occurred in 282 patients (77.7%) following HBOT: 15.2% fully recovered, 42.7% showed a significant improvement (and were expected to heal spontaneously), and 19.8% a slight improvement. CONCLUSIONS: HBOT can benefit the treatment of non-healing ischemic wounds (especially when aided by pretreatment TcPO2 evaluation; data not shown). Our experience shows that this procedure is safe and contributes to wound healing.

Is anemia at hospital admission associated with in-hospital acute kidney injury occurrence?

BACKGROUND: The effect of acute kidney injury (AKI) on anemia has been well-documented. However, the effect of 'preexisting' anemia on AKI has been less addressed. The aims of the present study were to investigate (1) the association between anemia at hospital admission and AKI occurrence, and (2) the effect of 'preexisting' anemia on the clinical outcomes of AKI. METHODS: A retrospective cohort study was undertaken among patients aged > or =17 years who were admitted to our hospital during the year 2006 (n = 34,802). Anemia at hospital admission and AKI occurrences were determined using the WHO definition and the RIFLE criteria, respectively. A subgroup of patients with an estimated glomerular filtration rate > or =60 ml/min/1.73 m(2) was analyzed separately to control for the effect of chronic kidney disease on anemia. RESULTS: The cumulative incidence of AKI was 11.2% in anemic patients at hospital admission, compared to 5.5% in nonanemic subjects. The association between anemia at admission and AKI occurrence remained statistically significant after controlling for potential confounders (odds ratio 1.5, 95% CI 1.4-1.6). In addition, an association between anemia at hospital admission and clinical outcomes of AKI was observed. CONCLUSION: Anemia at hospital admission should be recognized as a potential risk factor for in-hospital AKI occurrence.

Geographic and epidemiologic analysis of the cutaneous Leishmaniasis outbreak in northern Israel, 2000-2003.

BACKGROUND: The incidence of cutaneous leishmaniasis in northern Israel began to rise in 2000, peaking at 41.0 per 100,000 in the Kinneret subdistrict during the first half of 2003. OBJECTIVES: To examine the morbidity rates of CL in northern Israel during the period 1999-2003, which would indicate whether new endemic areas were emerging in this district, and to identify suspicious hosts. METHODS: The demographic and epidemiologic data for the reported cases (n=93) were analyzed using the GIS and SPSS software, including mapping habitats of suspicious hosts and localizing sites of infected sand flies. RESULTS: The maximal incidence rate in the district was found in the city Tiberias in 2003: 62.5/100,000 compared to 0-1.5/100,000 in other towns. The cases in Tiberias were concentrated on the peripheral line of two neighborhoods, close to the habitats of the rock hyraxes. Sand flies infected with Leishmania tropica were captured around the residence of those affected. Results of polymerase chain reaction were positive for Leishmania tropica in 14 of 15 tested patients. CONCLUSIONS: A new endemic CL area has emerged in Tiberias. The most suspicious reservoir of the disease is the rock hyrax.

Contrast-induced nephropathy among Israeli hospitalized patients: incidence, risk factors, length of stay and mortality.

BACKGROUND: Radiological procedures utilizing intravascular contrast media are being widely applied for both diagnostic and therapeutic purposes. This has resulted in the increasing incidence of procedure-related contrast-induced nephropathy. In Israel, data on the incidence of CIN and its consequences are lacking. OBJECTIVES: To describe the epidemiology of CIN among hospitalized patients in the Western Galilee Hospital, Nahariya (northern Israel), and to explore the impact of CIN on mortality and length of stay. METHODS: The study group was a historical cohort of 1111 patients hospitalized during the year 2006 who underwent contrast procedure and whose serum creatinine level was measured before and after the procedure. Data were electronically extracted from different computerized medical databases and merged into a uniform platform using visual basic application. RESULTS: The occurrence of CIN among hospitalized patients was 4.6%. Different CIN rates were noticed among various high risk subgroups such as patients with renal insufficiency and diabetes mellitus (14.1%-44%). Average in-hospital length of stay was almost twice as long among patients with CIN compared to subjects without this condition. Furthermore, the in-hospital death rate among CIN patients was 10 times higher. A direct association was observed between severity of CIN based on the RIFLE classification and risk of mortality. CONCLUSIONS: Low CIN occurrence was demonstrated in general hospitalized patients (4.6%), and high rates (44%) in selected high risk subgroups of patients (with renal insufficiency or diabetes mellitus). Furthermore, prolonged length of stay and high in-hospital mortality were directly related to CIN severity.

Reliability of vision screening tests for school children.

PURPOSE: Estimate the reliability of the E-chart as used with Israeli school children. DESIGN: Cross-sectional, population-based study conducted among 751 Israeli students of the Northern District, aged 6- and 7-year-olds and 13- and 14-years-old in 30 schools in 2003. METHODS: Each student was screened separately by two public health nurses using the illiterate E-chart. Collected data included the students' vision and demographic characteristics, the nurses' professional background, and whether they referred students for medical testing. The reliabilities of vision testing and of the recommendations were determined using total, positive, and negative percentages of agreement and Kappa coefficients. FINDINGS: Total percentage of agreement on vision (combined findings for both eyes) was 78.2% (Kappa 0.47, 95%CI 0.41-0.53). Logistic regression models to predict agreement on vision abnormality showed a higher percentage of agreement among females and 13- and 14-year-old students than among males and 6- and 7-year old students. Total agreement of 85.8% was found in referral recommendations (Kappa 0.58, 95%CI 0.51-0.65). Significant relationships were noted with student age, ethnicity, subdistrict of residence, nurse seniority, and agreement on vision findings. CONCLUSIONS: Improvement in school vision-screening reliability is needed, especially among 6- and 7-year-old students. To this end, the determinants of fair reliability should be investigated and training programs planned. Reasons for differences in the reliability of nurses' recommendations detected among subdistricts must be further studied, together with careful supervision, to ensure better performance and adherence to PHS guidelines. Implications for nurses and nursing should be considered. CLINICAL RELEVANCE: Demographic characteristics were found to predict reliability, which can guide nurses in selecting students who need more careful attention or closer supervision during vision testing.

Hospital-acquired acute kidney injury in Israel.

BACKGROUND: Acute kidney injury remains a common significant clinical problem. Yet there are scant data in Israel on the incidence of hospital-acquired AKI and on diagnosis validity. OBJECTIVES: To describe the epidemiology of AKI among hospitalized patients in the Western Galilee Hospital, Nahariya, compare discharge summaries to laboratory diagnosis, and investigate the impact of AKI on mortality and length of stay. METHODS: Computerized medical and laboratory data of 34,802 hospitalized subjects were collected. AKI was diagnosed according to three different definitions. We calculated the sensitivity and specificity of AKI based on ICD-9 diagnosis compared to patient's laboratory data as the gold standard. RESULTS: The overall AKI annual incidence rate was 1-5.1%, depending on the AKI definition used. The incidence of AKI based on ICD-9 diagnosis was significantly lower compared to the laboratory-based diagnosis. Average in-hospital length of stay was 2.4 times longer among patients with AKI compared to subjects without this condition. Furthermore, the in-hospital death rate among AKI patients was 14 times higher than among non-AKI hospitalized subjects, with a positive association between AKI severity and risk of death. CONCLUSIONS: Using AKI laboratory diagnosis as the gold standard revealed ICD-9 diagnosis to be 9.1% sensitive and 99.4% specific. Hospital-acquired AKI is a major contributor to prolonged length of stay and high mortality rates; therefore, interventions to reduce in-hospital disease incidence are required.

Vision screening among northern Israeli Jewish and Arab schoolchildren.

BACKGROUND: Uncorrected refractive error is the leading cause of visual impairment in children. In 2002 a screening project was launched in Israel to provide data on the effectiveness of the illiterate E-chart in identifying Jewish and Arab schoolchildren in need of a comprehensive eye examination. OBJECTIVES: To present the aims, design and initial results of the visual screening project and the prevalence of vision abnormality in the study population. METHODS: A cross-sectional population-based study was conducted during 2002-2003 among first- and eighth-graders in 70 schools in northern Israel. The nurse's test included use of the illiterate E-chart to measure visual acuity. The medical examination included vision history, clinical eye examination, VA and retinoscopy. The ophthalmologist's evaluation as to whether a child needed a referral for, diagnostic procedures, treatment and/or follow-up was recorded and compared with explicit referral criteria formulated after data collection. RESULTS: Of 1975 schoolchildren, 31% had abnormal VA, defined as VA worse than 6/6 in at least one eye, and a quarter had VA equal or worse than 6/12 in both eyes. The prevalence of vision abnormality among the children was 22.4% when based on the evaluation of the field ophthalmologist and 26.1% when based on two sets of explicit severity scores and referral criteria. CONCLUSIONS: Vision abnormality is a significant health problem among northern Israeli schoolchildren. This project is unique in scope and importance, providing evidence to assist policy making with regard to vision screening for schoolchildren (including data on test reliability and validity) and optimal VA cutoff level, and confirming the need for clinical guidelines regarding referral criteria.

Performance measures of the illiterate E-chart vision-screening test used in Northern District Israeli school children.

OBJECTIVES: To evaluate the screening performance of 6/6 and 6/12 vision cut-offs with an illiterate E-chart implemented by a public health nurse to test children for ocular abnormalities and uncorrected refractive error. The gold standard diagnosis is an eye examination performed by an ophthalmologist. SETTING: A cross-sectional population-based study was conducted among 2113 students' ages 6-7 and 13-14 years old in 70 Northern District Israeli schools. METHODS: Students were tested by nurses and ophthalmologists. A nurse examination was carried out using the illiterate E-chart for vision measurement. The medical examination included vision history, clinical eye examination, vision and retinoscopy testing. The Physician's evaluation of whether students needed a referral for diagnostic procedures, treatment and/or follow-up was recorded. Screening test's performance was determined using ophthalmologist's decision regarding referral as the gold standard. Detection rate (DR), false-positive rate (FPR), odds affected positive result (OAPR), positive predictive value (PPV) and negative predictive value (NPV) were estimated overall and by students' demographic characteristics. RESULTS: For vision >6/6 cut-off in at least one eye (eyes tested separately): DR - 71.9% (95% CI 65.8-78.7%), FPR - 22.8% (95% CI 17.9-28.9%), OAPR - 0.98:1 (95% CI 0.84:1-1.15:1), PPV - 52.7% (95% CI 45.4-61.2%), NPV - 90.9% (95% CI 88.7-93.1%). For 6/12 vision cut-off, namely vision 6/12 or worse in both eyes (tested separately): DR - 58.6 (95% CI 51.8-66.4%), FPR - 15.2% (95% CI 10.9-21.1%), OAPR - 1.13:1 (95% CI 0.94:1-1.35:1), PPV - 61.1% (95% CI 52.9-70.6%), NPV - 87.6% (95% CI 84.9-90.4%). CONCLUSIONS: Vision-screening test performance measures are mild. It is suggested to change vision cut-off level that denotes vision abnormality from current policy of vision not equal 6/6 in both eyes (tested separately) to vision 6/12 or worse in both eyes (tested separately). This change will result in reduction of FPR from 22% to 15%, concomitant with an increase in false-negative rate from 28% to 41%. Students may be equally screened by either a senior or a less experienced nurse.
