Development of a Cardiovascular Disease Risk Prediction Model: A Preliminary Retrospective Cohort Study of a Patient Sample in Saudi Arabia

Saudi Arabia has an alarmingly high incidence of cardiovascular disease (CVD) and its associated risk factors. To effectively assess CVD risk, it is essential to develop tailored models for diverse regions and ethnicities using local population variables. No CVD risk prediction model has been locally developed. This study aims to develop the first 10-year CVD risk prediction model for Saudi adults aged 18 to 75 years. The electronic health records of Saudi male and female patients aged 18 to 75 years, who were seen in primary care settings between 2002 and 2019, were reviewed retrospectively via the Integrated Clinical Information System (ICIS) database (from January 2002 to February 2019). The Cox regression model was used to identify the risk factors and develop the CVD risk prediction model. Overall, 451 patients were included in this study, with a mean follow-up of 12.05 years. Thirty-five (7.7%) patients developed a CVD event. The following risk factors were included: fasting blood sugar (FBS) and high-density lipoprotein cholesterol (HDL-c), heart failure, antihyperlipidemic therapy, antithrombotic therapy, and antihypertension therapy. The Bayesian information criterion (BIC) score was 314.4. This is the first prediction model developed in Saudi Arabia and the second in any Arab country after the Omani study. We assume that our CVD predication model will have the potential to be used widely after the validation study.

A Comparison of the Checklist Scoring Systems, Global Rating Systems, and Borderline Regression Method for an Objective Structured Clinical Examination for a Small Cohort in a Saudi Medical School

BACKGROUND

This study aims to compare the effectiveness of using the checklist and global rating scores to evaluate the clinical competency of medical students in Objective Structured Clinical Examinations (OSCEs). Additionally, the study assesses the appropriateness of using the borderline regression method to set standards for small-scale OSCE exams and determines if the estimated passing marks differ significantly from the university's prefixed passing score of 70%. The study also examines whether the university should utilize the borderline regression method to determine passing scores for each OSCE exam instead of a set passing score.

METHODS

The study analyzed medical students' grades in 11 OSCE exams in the 2022-2023 academic year at Alfaisal University, Riyadh, Saudi Arabia. Students received family medicine clerkship rotations, and after each rotation, they took an OSCE exam consisting of three stations that family medicine consultants graded. The exam included a checklist of 30 tasks and a five-level global rank scale. The study collected all the checklist marks and global rank grades and analyzed them using IBM® Statistical Package for Social Sciences (SPSS® Statistics) software. The statistical tests used were descriptive statistics, the T-test, chi-square tests, Fisher's exact test, and Pearson correlation.

RESULTS

The study showed that students were more likely to pass when using the global rating system than the checklist scoring system. Additionally, students had a significantly lower passing rate when using the higher cut-off passing score estimated using the borderline regression method compared to the pre-set passing score of 70% established by the university (with a p-value of 0.00).

CONCLUSION

Each scoring system has advantages and disadvantages, but they complement each other. Combining scoring systems can produce a more comprehensive and precise evaluation of a candidate's performance. The study also emphasizes the importance of carefully selecting and validating cut-off points in OSCE exams to ensure fairness and consistency in assessment.

COVID-19 pandemic impact on primary immunization uptake

Purpose/Background

Pediatricians across the world are seeing a steep drop in the number of children coming in for appointments due to COVID-19 pandemic. To prevent outbreaks of serious diseases that pose an even greater threat to children than COVID-19, it is important that children not skip their routine vaccines. The aim of this study was to determine the impact of COVID-19 pandemic on primary immunization activities in Saudi Arabia.

Settings and Design

Cross-sectional design.

Methods and Material

The study was conducted at a community pediatric clinic. All parents of preschool-age children who visited the community pediatric clinics were asked to complete a self-administrated questionnaire on primary immunization uptake during the pandemic.

Statistical Analysis Used

The Chi-square and Fisher's exact test were performed to examine the demographic differences between participants who missed vaccination during the pandemic and reasons for missing the vaccination.

Results

Three hundred study participants completed our questionnaire. In total, 90.6% of respondents were up to date with their vaccinations prior to the pandemic, and most respondents believed that children should be immunized at an appropriate age, it is essential for children to be fully immunized, vaccination is effective in preventing serious disease, and childhood immunization is essential during the pandemic (98.3%, 98.7%, 97.3%, and 93.7%, respectively). In total, 72.4% of respondents did not miss their vaccinations during the pandemic, while 26.6% missed vaccinations. The most common reason for missing vaccinations during the pandemic was transportation difficulty and curfew, followed by fear of contracting COVID-19 infection (40.9% and 35.5%, respectively). Those who did not believe that childhood immunization was necessary during the pandemic were more likely to miss vaccinations during the pandemic (P < 0.001). In addition, those who did not have a family member with COVID-19 infection were more likely not to miss the vaccine (P < 0.001). Moreover, those who thought taking vaccinations in a primary care setting or hospital is safe were more likely not to miss the vaccination during the pandemic (P < 0.027) and (P < 0.001).

Conclusions

Significant portion of the population was affected and missed immunizations during the pandemic. The perceptions on the importance of immunization and having a family member affected with COVID-19 during the pandemic were important factors in missing immunizations. Moreover, transportation and fear of contracting COVID-19 during the curfew were also common reasons for missing immunizations during the pandemic.

Assessing the Validity of Health Messages Used by the Saudi Public in WhatsApp

OBJECTIVE

WhatsApp is the most frequently used social media platform in Saudi Arabia. Inaccurate information could negatively impact public health. The number of studies worldwide investigating health-related misinformation in social media increased steadily, with limited data from Arabic-speaking communities. This study aimed to estimate the validity and safety of Arabic-language health information messages circulated on WhatsApp and identify the different categories of these messages based on their credibility.

PARTICIPANTS AND METHODS

A descriptive, analytical cross-sectional study was conducted from February to April 2021. A total of 374 students were randomly selected from the common first preparatory year college at King Saud University in Riyadh, Saudi Arabia, and participated by sharing up to three health-related WhatsApp messages per student that they or their relatives had recently read. Four board-certified physicians reviewed and classified the messages based on their credibility and sources.

RESULTS

282 students provided 326 messages (1.2 messages per student). Most messages (86%) had either invalid or inaccurate content, and 83.7% came from unknown sources. Only 26 messages (8%) of the total were written by trusted scientific sources. Most of the messages from unknown sources or unqualified persons were either invalid or invalid, with potential health risks for the public, and the difference from trusted sources was statistically significant.

CONCLUSION

This study showed a high percentage of inaccurate and invalid health-related messages on WhatsApp. Invalid messages with potential health risks were authored mostly by unknown sources or unqualified persons. Most health messages written by trusted authorities and qualified persons were valid. Trusted scientific authorities should thus be more active in public education on social media platforms. They should advise their communities on how to discern the validity of such messages. More efforts are needed to guide patients from where to obtain accurate and valid health information.

Association Between Vitamin D Levels and Glycemic Control Among Adult Diabetic Patients in Riyadh, Saudi Arabia

Background: Diabetes is one of the most common diseases worldwide. It can cause serious complications, such as cardiovascular events, end-stage renal disease, and blindness if not controlled. Vitamin D is believed to play an essential role in glucose metabolism and insulin resistance. However, few studies have been conducted in Saudi Arabia to confirm or reject this hypothesis. Thus, this study explored the relationship between vitamin D levels and glycemic control in a Saudi diabetic population.

Materials and methods: This is a retrospective cohort study including all adults 18 years of age or older diagnosed with diabetes who underwent at least five years of regular follow-up at the family medicine clinic at the King Faisal Specialist Hospital (KFSH) from January 2015 to January 2021. Data were obtained from the patients’ medical records and included detailed histories, physical examination records, and laboratory findings. Participants were divided into vitamin D deficiency and vitamin D sufficiency groups based on vitamin D levels.

Results: A total of 370 patients with type 2 diabetes mellitus were enrolled in the study. The majority of the patients (60%) were over 65 years of age. The mean serum 25(OH) vitamin D level of the participants was 62.75 ± 22.79 nmol/L. There was a significant association between glycemic control and vitamin D levels (p < 0.001). The mean level of vitamin D was higher in the good glycemic control group (70.96 ±22.66) than in the poor glycemic control group (54.81 ±19.98). A total of 13.74% (25) of the good glycemic control group had vitamin D levels < 50 nmol/L, while 52.13% (98) of the poor glycemic control had vitamin D levels < 50 nmol/L. Patients with poor glycemic control were 2.4 times more likely to have low vitamin D levels than patients in the well-controlled glycemic group.

Conclusion: Based on the study results, serum vitamin D has a significant inverse relationship with HbA1c levels among diabetics. This finding highlights the need for routine screening of vitamin D status in all patients with diabetes and early treatment for those found to be deficient.

The Prognostic Value of Coronary Arteries Calcium Scoring in a Primary Health Care Setting in Riyadh, Saudi Arabia: A Retrospective Cohort Study

Background/Purpose: Coronary Artery Calcium Scoring (CACS) by CT, the American Atherosclerotic Cardiovascular Disease (ASCVD) Score, and the British Cardiovascular Risk (QRISK2) score are the most frequently used cardiovascular risk stratification scores to predict cardiac outcomes and aid in the decision of implementing preventative and/or interventional measures. The aim of this study is to assess CACS, ASCVD score, QRISK2 score, and their capacity to predict cardiovascular events among family medicine patients in King Faisal Specialist Hospital and Research Centre (KFSH&RC), Riyadh, Saudi Arabia.

Methodology: All medical records of patients (18 years and above) who had a CACS done in Family Medicine Clinics at KFSH&RC from January 2010 to March 2018 were reviewed, retrospectively. The study variables included demographics, comorbidities, CACS, ASCVD Score, QRISK2 score, and cardiovascular events.

Results: We included 218 patients. Our study population included: 77% men, a mean age of 51 years (SD±8), and a mean BMI of 29 kg/m2 (SD±5). CACS was significantly associated with coronary events (p-value < .05). There was significant association between high CACS (>400) and family history of cardiac disease (p-value = .006), prior cardiovascular events (p-value = .01) and advancing age (p-value < .001). High concordance was found between QRISK2 score and CACS (90.6%), and moderate concordance between ASCVD score and CACS (69.4%). Moderate concordance was found between ASCVD score and QRISK2 score (74.3%). The majority of the subjects (88%) fell into the low-risk group (CACS <100) with (63%) having a CACS of zero.

Conclusion: QRISK2 cardiac assessment tool provides better risk assessment and higher concordance with CACS. To improve cost-effectiveness and minimize unnecessary radiation exposure, QRISK2 scoring should be implemented for initial cardiovascular risk stratification prior to ordering the CACS imaging modality.

Attitude and hesitancy of human papillomavirus vaccine among Saudi parents

Background:

Human papillomavirus (HPV) is closely associated with cervical cancer. The HPV vaccine is expected to protect against two-thirds of cervical cancer cases in Saudi Arabia.

Objectives:

To determine the awareness and attitude regarding the HPV vaccine among Saudi parents attending family medicine clinics in Riyadh.

Materials and Methods:

All Saudi parents of patients of Family Medicine Pediatric Clinics, King Faisal Specialist Hospital and Research Centre (KFSH&RC), Riyadh, were invited to participate in this study between November 2019 and May 2020. A culturally sensitive and specially designed questionnaire was administered using an interview-based model. The data collected included sociodemographic information, knowledge of HPV and its vaccine, and attitudes regarding HPV acceptance.

Results:

A total of 296 study participants completed our questionnaire on the HPV vaccine. About 70.6% of the participants were not aware of the HPV vaccine and the majority of them either did not know or did not associate HPV as an etiology for cervical cancer (38.8 and 37.8%, respectively). Only 28.6% of the participants were aware that cervical cancer can be prevented by a vaccine and 89.5% of the study participants did not receive the HPV vaccine for themselves or their children. The employee status was significantly associated with a history of receiving the HPV vaccine (χ² (2) = 10.607, P =0.005), while age and the level of education had a statistically significant relationship with planning on having the HPV vaccine ((χ² (9) = 51.841, P <.001) and (χ² (12) = 23.977, P =0.02), respectively). The level of awareness of the HPV vaccine was significantly associated with a history of having the HPV vaccine; (χ² (1) = 38.486, P <.001) as well as with planning on having the HPV vaccine (χ² (1) = 38.486, P <.001). Moreover, the reasons for hesitancy were a statistically significant factor for unvaccinated respondents who were not planning to have the HPV vaccine (χ² (21) = 97.689, P <.001) while it was not significantly associated with the unvaccinated respondents who were planning to have the HPV vaccine (χ² (9) = 6.989, P =.63).

Conclusion:

Our study clearly demonstrated a poor level of awareness and attitude toward the HPV vaccine among Saudi parents. A higher level of awareness of the HPV vaccine was significantly associated with planning on having the vaccine. There is a need for effective awareness programs for better HPV-related education in order to increase the acceptance of the HPV vaccine among Saudi parents.

Incidence of Cardiovascular Complications and Nephropathy in Patients with Type 2 Diabetes in a Primary Care Setting in Riyadh, Saudi Arabia

BACKGROUND

Diabetes mellitus is prevalent in Saudi Arabia. Our study aims to estimate the rate and time of developing macrovascular and microvascular complications in diabetic patients in a primary care setting.

METHODOLOGY

This is a retrospective cohort study. All collected data were retrieved using medical files and the electronic patient records of all diabetics having regular follow-ups in Family Medicine clinics, King Faisal Specialist Hospital & Research Centre in Riyadh, Saudi Arabia, from the beginning of January 2002 to the end of December 2018. The data included the demographics of patients diagnosed with diabetes mellitus, their HbA1c, and the follow-up duration of the development of complications, which included cardiovascular complications and diabetic nephropathy.

RESULTS

We included 365 patients, of whom 47.1% males and 52.9% were females. The mean age of diabetes mellitus diagnosis in our population was 50 years (SD±11.3). The mean duration of follow-up was 7.14 years (SD±3.9). The rate of developing cardiovascular complications and diabetic nephropathy was 11.2% and 10.4%, respectively. The mean time to develop cardiovascular complications and diabetic nephropathy was 6 (SD±3.9) and 5.24 (SD±3.2) years, respectively. The mean time to develop the first diabetes complication was 5.5 years (SD±3.6). There was no statistical significance in the mean of HbA1c between patients who developed diabetic complications and those who did not.

CONCLUSION

Diabetes complications are common in the Saudi community. The duration of the development of cardiovascular complications and diabetic nephropathy was shorter than that indicated in international and national reports. Robust screening programs to diagnose and improve the control of diabetes mellitus should be established in the Kingdom.

Potential health risks of maternal phthalate exposure during the first trimester - The Saudi Early Autism and Environment Study (SEAES)

Phthalates are the most ubiquitous contaminants that we are exposed to daily due to their wide use as plasticizers in various consumer products. A few studies have suggested that in utero exposure to phthalates can disturb fetal growth and development in humans, because phthalates can interfere with endocrine function. We collected spot urine samples from 291 pregnant women in their first trimester (9.8 ± 2.3 gestational weeks) recruited in an ongoing prospective cohort study in Saudi Arabia. A second urine sample was collected within 1-7 d after enrollment. The aims of this study were to: (1) assess the extent of exposure to phthalates during the first trimester and (2) estimate the risk from single and cumulative exposures to phthalates. Most phthalate metabolites' urinary levels were high, several-fold higher than those reported in relevant studies from other countries. The highest median levels of monoethyl phthalate, mono-n-butyl phthalate (MnBP), mono-iso-butyl phthalate (MiBP), and mono-(2-ethylhexyl) phthalate (MEHP) in μg/l (μg/g creatinine) were 245.62 (197.23), 114.26 (99.45), 39.59 (34.02), and 23.51 (19.92), respectively. The MEHP levels were highest among three di (2-ethylhexyl) phthalate (DEHP) metabolites. %MEHP₄, the ratio of MEHP to four di (2-ethylhexyl) phthalate metabolites (∑₄DEHP), was 44%, indicating interindividual differences in metabolism and excretion. The hazard quotient (HQ) of individual phthalates estimated based on the reference dose (RfD) of the U.S. Environmental Protection Agency indicated that 58% (volume-based) and 37% (creatinine-based) of the women were at risk of exposure to ∑₄DEHP (HQ > 1). Based on the tolerable daily intake (TDI) from the European Food Safety Authority, 35/12% (volume-/creatinine-based data) of the women were at risk of exposure to two dibutyl phthalate (∑DBP) metabolites (MiBP and MnBP). The cumulative risk was assessed using the hazard index (HI), the sum of HQs of all phthalates. The percentages of women (volume-/creatinine-based data) at health risks with an HI > 1 were 64/40% and 42/22% based on RfD and TDI, respectively. In view of these indices for assessing risk, our results for the anti-androgenic effects of exposing pregnant women to ∑₄DEHP and ∑DBP early during pregnancy are alarming.

The impact of the implementation of a clinical decision support system on the quality of healthcare services in a primary care setting

Background

In July 2015, King Faisal Hospital Family Medicine clinics (KFH-FMC) successfully implemented a paperless, fully integrated, electronic healthcare system. The aim of this study is to evaluate the impact of moving to a fully integrated electronic medical record system, with clinical decision support (CDS) systems, on the quality of healthcare services in a primary care setting. We aim to evaluate the impact of CDS on clinical outcomes such as screening and diagnosis of breast and colorectal cancers, as well as the management of chronic diseases such as diabetes and hypertension, and the uptake of immunizations.

Inclusion and Exclusion Criteria

Our study included all adult patients, over the age of 18, registered in the Family Medicine clinic linked to King Faisal Hospital, seen between January 2012 and December 2018.

Design

Retrospective cohort study.

Setting

Family Medicine clinics at King Faisal Hospital (KFH-FMC).

Materials and Methods

Data were collected retrospectively from the electronic health records of all adult patients above 18 years of age, who were seen in KFH-FMC between January 2012 and December 2018. We analyzed several processes of care and a number of clinical outcomes, comparing results for the three and a half years before CDS implementation with the three and a half years after implementation. Data collected included blood pressure measurements, lipid levels, HbA1c for diabetic patients, screening tests done, including PAP smear, mammogram, fecal occult blood tests, and bone densitometry. Other data included cancer diagnoses and immunizations received.

Results

Significant increases were found in adult vaccine uptake ranging from an 11-fold increase in influenza uptake, to a 22-fold increase in pneumococcal 23 uptake. The uptake of all the cancer screening tests increased (FOB 66%, mammogram 33%, PAP smear 16%). Diagnoses of breast and colorectal cancer showed significant increases. Breast cancer diagnoses increased from 2 to 14, and colorectal cancer from 3 to 11. No significant improvement was found in chronic disease outcomes.

Discussion

The electronic health record with CDS led to significantly improved uptake of immunizations and screening tests, with earlier diagnoses of breast and colon cancer. Evidence of improvement in chronic disease outcomes is still lacking.

Sick Leaves Pattern in a Tertiary Healthcare Facility in Saudi Arabia

Background

Frequent sick leaves in any healthcare organization is a critical problem that can undermine the patients' care through increasing the workload on other co-workers and costing the organization a lot of money.

Methods

This is a quantitative cross-sectional study looking at the frequency of sick leaves among employees of a large, tertiary healthcare facility in Riyadh. We randomly selected 474 employees, who were seen in family medicine clinics during a one-year period. We collected all the data retrospectively from their electronic medical records. Then we reviewed and analyzed all the data using SPSS software version 26.0 (IBM Corp., Armonk, NY).

Results

There was no difference in the sick leaves rate between males and females (p-value = 0.8618), but we saw a higher rate among younger employees (40 years old or less) compared to those 41 years or older (p-value <0.0001). We also investigated those who took four sick leaves or more during the period of the study, and we found that majority of them were nursing staff (31.71%), hospital assistances (24.39%) and housekeepers (14.63%). The commonest cause for taking sick leave in our study was viral upper respiratory tract infection (VURTI). Therefore, we studied the effect of influenza vaccine on the frequency of sick leaves and we found that those who took the vaccine were less likely to take a leave because of flu (p-value <0.0001, odds ratio 0.4067 with 95% CI: 0.2739-0.608).

Conclusion

Younger employees, nurses, hospital assistants and housekeepers are more likely to take sick leaves. Flu is the leading cause of sick leaves and influenza vaccine seemed to reduce its rate. In this study, we also discussed different methods that can be used by any healthcare organization to reduce the absence rate. Further studies are required to better manage the issue of excessive sick leaves.

Diagnostic Accuracy of Body Mass Index (BMI) When Diagnosing Obesity in a Saudi Adult Population in a Primary Care Setting, Cross Sectional, Retrospective Study

BACKGROUND

Obesity is a risk factor that leads to many chronic diseases and, unfortunately, its prevalence in Saudi Arabia is on the rise. To successfully manage obesity and its complications, patient must be accurately diagnosed. This study aims to investigate the diagnostic accuracy of body mass index (BMI) when diagnosing obesity within the Saudi population using body fat percentage (BF%) as the gold standard.

MATERIALS AND METHODS

This is a cross-sectional study that includes a calculated sample size of 942 subjects. Subjects were recruited from family medicine clinics that were linked to King Faisal Specialist Hospital and Research Centre (KFSH&RC) in Riyadh, Saudi Arabia from January 2005 to March 2016. BF% was estimated using DEXA scan. The diagnostic accuracy of BMI was assessed by using the WHO and the American Association of Clinical Endocrinologists and American College of Endocrinology (AACE/ACE) reference standard for obesity of BF% >25% in men and >35% for women.

RESULTS

Findings indicate, out of the study population, 29% of men and 53% of women are obese using BMI-defined obesity cut-off point 30 kg/m2. The prevalence of obesity was 83.9% and 97.3% in men and women, respectively, using BF%-defined obesity, which corresponds to BMI cut-off of 24 kg/m2. Even when considering the highest acceptable BF% based on the mean age of our participants (33% for men and 43% for women), the BMI cut-off to diagnose obesity should not exceed 27 kg/m2 among men and women in Saudi Arabia.

CONCLUSION

The accuracy of BMI 30 kg/m2 to diagnose obesity among the Saudi population is limited. We have to lower the BMI cut-off point to improve its sensitivity as a screening tool for obesity. Our study suggests that the BMI cut-off point among Saudis and possibly the Arab population should not exceed 27 kg/m2 for both sexes.

Prevalence of lipid abnormalities and cholesterol target value attainment in patients with stable coronary heart disease or an acute coronary syndrome in Saudi Arabia

Objectives:

To provide an overview of the extent of hyperlipidemia in very high-risk patients, and how lipid-lowering therapy (LLT) is used in a real-world setting.

Methods:

In this multicenter observational study, data were collected from LLT-treated patients with stable CHD or an ACS in Saudi Arabia between 2013 and 2014. Individuals were included if they were >18 years and had a full lipid profile available, recorded either prior to the baseline physician visit (CHD patients) or within 24-hours of admission to hospital (ACS patients).

Results:

A total of 737 patients were included in the study, 597 with stable CHD and 140 with ACS. Few patients in either group had an LDL-C level of <70 mg/dl, which is advocated for very high-risk patients (24.3% and 11.4%, respectively). The median distances to this value were 19.0 mg/dl (CHD) and 25.0 mg/dl (ACS). Low doses of statins were being utilized (31 and 24 mg/day for CHD and ACS, respectively), with only minimal intensification for the ACS patients after hospital admission (41 mg/day at follow-up).

Conclusions:

Achievement of recommended LDL-C levels was poor for patients with stable CHD or an ACS. Statin intensity was low, indicating huge scope for intensifying the treatment of these very high-risk patients.

Prevalence of Mild Cognitive Impairment and Dementia in Saudi Arabia: A Community-Based Study

Introduction

The age of the population in Saudi Arabia is shifting toward elderly, which can lead to an increased risk of mild cognitive impairment (MCI) and dementia.

Objective

The aim of this study is to determine the prevalence of cognitive impairment (MCI and dementia) among elderly patients in a community-based setting in Riyadh, Saudi Arabia.

Methods

In this cross-sectional study, we included patients aged 60 years and above who were seen in the Family Medicine Clinics affiliated with King Faisal Specialist Hospital and Research Centre. Patients with delirium, active depression, and patients with a history of severe head trauma in the past 3 months were excluded. Patients were interviewed during their regular visit by a trained physician to collect demographic data and to administer the validated Arabic version of the Montreal Cognitive Assessment (MoCA) test.

Results

One hundred seventy-one Saudi patients were recruited based on a calculated sample size for the aim of this study. The mean age of included sample was 67 ± 6 years. The prevalence of cognitive impairment was 45%. The prevalence of MCI was 38.6% and the prevalence of dementia was 6.4%. Age, low level of education, hypertension, and cardiovascular disease were risk factors for cognitive impairment.

Conclusion

Prevalence of MCI and dementia in Saudi Arabia using MoCA were in the upper range compared to developed and developing countries. The high rate of risk factors for cognitive impairment in Saudi Arabia is contributing to this finding.

Non-therapeutic infant male circumcision. Evidence, ethics, and international law perspectives

Objectives:

To review the evidence of the benefits and harms of infant male circumcision, and the legal and ethical perspectives of infant male circumcision.

Methods:

We conducted a systematic search of the literature using PubMed, EMBASE, and the Cochrane library up to June 2015. We searched the medical law literature using the Westlaw and Lexis Library law literature resources up to June 2015.

Results:

Male circumcision significantly reduced the risk of urinary tract infections by 87%. It also significantly reduced transmission of human immunodeficiency virus among circumcised men by 70%. Childhood and adolescent circumcision is associated with a 66% reduction in the risk of penile cancer. Circumcision was associated with 43% reduction of human papilloma virus infection, and 58% reduction in the risk of cervical cancer among women with circumcised partners compared with women with uncircumcised partners. Male infant circumcision reduced the risk of foreskin inflammation by 68%.

Conclusion:

Infant male circumcision should continue to be allowed all over the world, as long as it is approved by both parents, and performed in facilities that can provide appropriate sterilization, wound care, and anesthesia. Under these conditions, the benefits of infant male circumcision outweigh the rare and generally minor potential harms of the procedure.

The Relationship between 25 (OH) D Levels (Vitamin D) and Bone Mineral Density (BMD) in a Saudi Population in a Community-Based Setting

BACKGROUND

Vitamin D deficiency has been linked to an increased risk of osteoporosis. Vitamin D deficiency has reached high levels in the Saudi population, but there is conflicting evidence both in the Saudi population, and worldwide, regarding the existence of a correlation between these low vitamin D levels and reduced BMD (bone mineral density), or osteoporosis.

OBJECTIVE

The objective of this study was primarily to determine whether there was a correlation between vitamin D deficiency and osteoporosis in the Saudi population. We aimed to investigate whether the high levels of vitamin D deficiency and insufficiency would translate to higher prevalence of osteoporosis, and whether there is a correlation between vitamin D levels and bone mineral density.

MATERIALS AND METHODS

This was a community based cross sectional study conducted in the Family Medicine Clinics at King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia. Electronic records of 1723 patients were reviewed. Laboratory and radiology results were collected, including vitamin D levels, calcium levels, and bone mineral density scan results.

RESULTS

Among the whole population, 61.5% had moderate to severe vitamin D deficiency with levels less than 50nmol/L. 9.1% of the population had osteoporosis, and 38.6% had osteopenia. Among the whole population, there was no significant correlation between spine or total femoral BMD and serum 25(OH) D.

CONCLUSION

Vitamin D deficiency is prevalent in the Saudi population. However, no correlation has been found between vitamin D deficiency and reduced bone mineral density in any age group, in males or females, Saudis or Non-Saudis, in our population in Riyadh, Saudi Arabia.

Attitudes and perceptions towards HPV vaccination among young women in Saudi Arabia

Background:

Rising incidence of human papillomavirus (HPV) infection and cervical cancer can be reduced by effective vaccination. Saudi Food and Drug Administration approved prophylactic HPV vaccine in 2010 for females of 11–26 years.

Objectives:

To determine the awareness of HPV infection, its health sequel and the attitude and barriers to the acceptance of HPV vaccine by young women in Saudi Arabia. Dynamics influencing the decision of patients and parents regarding vaccination were assessed to foster effective and strategically focused interventions.

Materials and Methods:

All patients of Family Medicine department, King Faisal Specialist Hospital and Research Center, Riyadh were invited to participate in this study from January 2012 to June 2014. A culturally sensitive and specially designed questionnaire was administered using an interview-based model to assess the knowledge, perception, and associated sociodemographic factors of HPV.

Results:

A total of 325 patients participated as per the inclusion criteria: 87.4% were Saudis, 53.5% had university or higher education and 65.2% were adolescents (age 11-19 years). The questionnaire was answered by participants (50.8%) or guardians (49.2%). About 34.5% of the population was aware of HPV infection, and 27.4% were aware of its relation with cervical cancer. However, awareness of the HPV vaccine, perception of its prevention of cervical cancer and other HPV-related disease was relatively low (32.3%), Saudis (29.9%) versus non-Saudis (48.8%) (P = 0.016). More guardians (41.2%) were aware of the HPV vaccine and its impact than participants (27.9%) (P = 0.01). Higher educational background (43.1%) increased the knowledge of HPV compared to less than high school education (24.5%) (odds ratio: 2.33; 95% confidence interval: 1.44–3.76). Nearly 64.3% of participants agreed, and 35.7% refused to receive the HPV vaccine.

Conclusion:

Knowledge and perception of HPV infection as an sexually transmitted infections and its vaccine was significantly low in this cohort of patients. Higher age and educational levels directly correlated with increased knowledge of HPV infection and its complications. It is recommended that awareness should be raised, and access to HPV vaccination increased to help reduce the health care burden of HPV sequelae in the Kingdom.

Management of vaginal penetration phobia in Arab women: a retrospective study

BACKGROUND AND OBJECTIVES

Vaginal penetration phobia is a common and distressing problem world.wide. It interferes with vaginal penetrative sexual relations, and leads to unconsummated marriage (UCM). This problem may be heightened in Arab women, due to cultural taboos about pain and bleeding, that may be associated with the first coital experience after marriage. Data about this problem is scarce in Arab societies. The aim of this study was to evaluate the response of these women and their husbands to an individualized, psychotherapeutic assessment and treatment to resolve this problem.

DESIGN AND SETTINGS

Retrospective descriptive in a general gynecology community setting over a 6-year period.

METHODS

The study involved a retrospective sequential cohort of 100 Arab couples with UCM due to the woman's VPP. They were evaluated by a female gynecologist in out patient clinics. Data was collected through chart review, and telephone interviews. Final analysis was performed on 100 Arab couples, who satisfied the inclusion criteria. They were followed up to assess their response to an individualized, structured treatment protocol. The treatment combined sex education with systematic desensitization, targeting fear and anxiety as.sociated with vaginal penetration.

RESULTS

A total of 96% of the studied group had a successful outcome after an average of 4 sessions. Penetrative intercourse was reported by the tolerance of these women; further pregnancy was achieved in 77.8 % of the infertile couples.

CONCLUSION

Insufficient knowledge of sexual intercourse is a major contributor to the development of VPP in the sampled population. It appears that they respond well to an individualized, structured treatment protocol as described by Hawten 1985 (regardless of other risk factors associated with vaginismus).

The pharmacoeconomic picture in Saudi Arabia

Saudi Arabia is the largest country in the region and it is the largest oil producing country in the world. It is one of the few countries in the world which was not affected significantly by the global economic crisis. Health care spending is led mainly by governmental expenditure. Private sector share of the health care services is supported by the government and increasing. The demands for pharmaceutical products, medical devices and health care services is fueled by the rapidly growing population and the wide spread of chronic diseases. Publications and expertise in the field of pharmacoeconomics is scarce within the country. There is an urgent need to establish a national center for pharmacoeconomics to lead the country efforts in controlling the cost of health care services. Such a center is needed to promote pharmacoeconomics research and train health care professionals in this field.

The sensitivity and specificity of screening mammography in primary care setting in Saudi Arabia

e12551

Background: Breast cancer is the leading cancer diagnosed in women in Saudi Arabia, accounting for 25% of all cancers diagnosed in women. The mammogram screening program at King Faisal Specialist Hospital and Research Center (KFSHRC) is the only structured screening program in the country. KFSHRC provides primary care services for a catchment population of 30,000 patients. This program covers all women above the age of 40 within this catchment population. Methods: A retrospective review of electronic and paper records were reviewed for mammograms done between January 2002- January 2012. Summary statistics were used to describe patient and examination characteristics. Results from mammograms were reported using the Breast Imaging Reporting and Data System (BI-RADS) of the American College of Radiology. The stage of diagnosis was reported using the American Joint Committee on Cancer (AJCC) system using stages one through four. ACR BIRADS classification and cancer status definitions mammograms were linked with cancer outcomes to identify true-positive, true-negative, false-positive, and false-negative examinations. On the basis of these classifications, sensitivity, specificity, positive predictive value, and negative predictive value were estimated. All mammograms and tissue biopsies were read by board certified specialists. Results: During the first round of screening 1694 mammograms were analyzed, and 12 cases of cancer were diagnosed. Cancer detection rate (per 1000 examination) was 7.1. Biopsy rate was 3.7 per 100 mammograms. Follow up ultrasounds rate was 2.7 per 100 mammograms. Sensitivity of mammogram screening was 80%, and specificity was 76%. Conclusions: The yield of a structured mammogram screening program in Saudi Arabia is high. There is a need to implement a national program for breast cancer screening in Arabian world in general and within Saudi Arabia in particular.

The attitude of health care professionals towards accreditation: A systematic review of the literature

Accreditation is usually a voluntary program, in which authorized external peer reviewers evaluate the compliance of a health care organization with pre-established performance standards. The aim of this study was to systematically review the literature of the attitude of health care professionals towards professional accreditation. A systematic search of four databases including Medline, Embase, Healthstar, and Cinhal presented seventeen studies that had evaluated the attitudes of health care professionals towards accreditation. Health care professionals had a skeptical attitude towards accreditation. Owners of hospitals indicated that accreditation had the potential of being used as a marketing tool. Health care professionals viewed accreditation programs as bureaucratic and demanding. There was consistent concern, especially in developing countries, about the cost of accreditation programs and their impact on the quality of health care services.

Impact of accreditation on the quality of healthcare services: a systematic review of the literature

BACKGROUND AND OBJECTIVE

Accreditation is usually a voluntary program in which trained external peer reviewers evaluate a healthcare organization's compliance and compare it with pre-established performance standards. The aim of this study was to evaluate the impact of accreditation programs on the quality of healthcare services

METHODS

We did a systematic review of the literature to evaluate the impact of accreditation programs on the quality of healthcare services. Several databases were systematically searched, including Medline, Embase, Healthstar, and Cinhal.

RESULTS

Twenty-six studies evaluating the impact of accreditation were identified. The majority of the studies showed general accreditation for acute myocardial infarction (AMI), trauma, ambulatory surgical care, infection control and pain management; and subspecialty accreditation programs to significantly improve the process of care provided by healthcare services by improving the structure and organization of healthcare facilities. Several studies showed that general accreditation programs significantly improve clinical outcomes and the quality of care of these clinical conditions and showed a significant positive impact of subspecialty accreditation programs in improving clinical outcomes in different subspecialties, including sleep medicine, chest pain management and trauma management.

CONCLUSIONS

There is consistent evidence that shows that accreditation programs improve the process of care provided by healthcare services. There is considerable evidence to show that accreditation programs improve clinical outcomes of a wide spectrum of clinical conditions. Accreditation programs should be supported as a tool to improve the quality of healthcare services.

Assessment of the accreditation standards of the Central Board for Accreditation of Healthcare Institutions in Saudi Arabia against the principles of the International Society for Quality in Health Care (ISQua)

BACKGROUND AND OBJECTIVES

Accreditation is usually a voluntary program, in which trained external peer reviewers evaluate health care organization's compliance with pre-established performance standards. Interest in accreditation is growing in developing countries, but there is little published information on the challenges faced by new programs. In Saudi Arabia, the Central Board for Accreditation of Healthcare Institutions (CBAHI) was established to formulate and implement quality standards in all health sectors across the country. The objective of this study was to assess a developing accreditation program (CBAHI standards) against the International Society for Quality in Health Care (ISQua) principles to identify opportunities for improvement of the CBAHI standards.

METHODS

A qualitative appraisal and assessment of CBAHI standards was conducted using the published ISQua principles for accreditation standards.

RESULTS

The CBAHI standards did not describe the process of development, evaluation or revision of the standards. Several standards are repetitive and ambiguous. CBAHI standards lack measurable elements for each standard. CBAHI standards met only one criterion (11.1%) of the Quality Improvement principle, two criteria (22.2%) of Patient/Service User Focus principle, four criteria (40%) of the Organizational Planning and Performance principle, the majority (70%) of the criteria for the safety principle, only one criteria (7.1%) for the Standards Development principle, and two criteria (50%) of the Standards Measurement principle.

CONCLUSIONS

CBAHI standards need significant modifications to meet ISQua principles. New and developing accreditation programs should be encouraged to publish and share their experience in order to promote learning and improvement of local accreditation programs worldwide.

The role of vitamin E in the prevention of cancer: a meta-analysis of randomized controlled trials

BACKGROUND

There are conflicting results in published randomized controlled trials (RCTs) on the role of vitamin E in the prevention of cancer. We conducted a meta-analysis of RCTs to evaluate the role of vitamin E in the prevention of cancer in adults.

METHODS

We included RCTs in which the outcomes of the intake of vitamin E supplement alone or with other supplements were compared to a control group. The primary outcomes were total mortality, cancer mortality, total incidence of cancer, and incidence of lung, stomach, esophageal, pancreatic, prostate, breast and thyroid cancers. All identified trials were reviewed independently by the two reviewers to determine whether trials should be included or excluded. The quality of all included studies was scored independently by the two reviewers.

RESULTS

Twelve studies, which included 167025 participants, met the inclusion criteria. There were no statistically significant differences in total mortality (relative risk, 0.99; 95% CI, 0.96-1.03) among the different groups of patients included in this meta-analysis. Vitamin E was associated with a significant reduction in the incidence of prostate cancer (relative risk, 0.85; 95% CI, 0.73-0.96, number needed to treat=500), but it did not reduce the incidence of any other types of cancer.

CONCLUSIONS

Vitamin E supplementation was not associated with a reduction in total mortality, cancer incidence, or cancer mortality, but it was associated with a statistically significant reduction in the incidence of prostate cancer. Vitamin E can be used in the prevention of prostate cancer in men who are at high risk of prostate cancer.

Towards evidence-based medical education in Saudi medical schools

(EBME) [corrected] is an attitude of mind that entails the creation of a culture in which teachers think critically about what they are doing, look at the best evidence available and on this basis, make decisions about their teaching practice, and subsequently, undertake the necessary revision and change. More medical schools have opened in Saudi Arabia in the last few years than have existed over the last three decades. Currently, the education of health professionals is based on assumption and traditions and rarely on research findings. Medical teaching has evolved from being opinion-based to evidence-based and the art of teaching is rapidly becoming the 'science' of teaching. The need for evidence in our teaching and medical education practices is as important as it is in assessing a new therapy. This approach to education is not only associated with better results in terms of better learning, from the side of the students (the consumers), but also has a wider impact on patient care and the community. Moreover, in this age of accountability, litigations and quality assurance, the need for BEME becomes greater. Some suggestions to implement BEME in Saudi Arabia have been put forward and these are the training of medical education professionals in the use the existing information systems, and disseminating information through the creation of a BEME journal (secondary publication) that publishes a critically appraised summary of medical education articles that are both valid and of immediate clinical use.

The role of vitamin E in the prevention of cancer: Meta-analysis of randomized controlled trials

1017

Background: Several in vitro studies showed antioxidant vitamins to have a significant protective effect against cancer. We did a meta-analysis of Randomized Controlled Trials (RCTs) to evaluate the role of vitamin E supplements in the prevention of Cancer in adults Methods: We included RCTs, in which outcomes of the intake of vitamin E supplement alone or with other supplements, were compared to a control group.The primary outcomes were total mortality, cancer mortality, total incidence of Cancer, incidence of Lung, stomach, esophageal, pancreatic, prostate, breast and thyroid cancers. All identified trials were reviewed independently by the two reviewers to determine whether trials should be included or excluded. The quality of all included studies was scored independently by the two reviewers. RevMan, version 4.2 was used for the data analysis. Results: Twelve studies met inclusion criteria, including 167025 participants. There were no statistically significant differences in total mortality (RR 0.99; 95%CI 0.96–1.03), cancer incidence (OR 0.96; 95%CI 0.92, 1.01), and cancer mortality (OR 1.00; 95%CI 0.96–1.03) among the different groups of patients included in this meta-analysis. Vitamin E did not reduce the incidence of any type of cancer that was available for analysis; However there was a statistically significant reduction in the incidence of prostate cancer in patients receiving vitamin E, RR 0.85 [0.73–0.96, NNT=500]. Conclusions: Vitamin E supplementation was not associated with a reduction in total mortality or cancer incidence, and cancer mortality, but it was associated with a statistically significant reduction in the incidence of prostate cancer. Vitamin E can be used in the prevention of Prostate cancer in men who are at high risk of prostate cancer.
