Epidemiology, clinical characteristics and risk factors of COVID-19 among children in Saudi Arabia: a multicenter chart review study.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) has affected over 100 million cases worldwide. Children accounted for 1-5% of all cases with less reported symptoms and better prognosis compared to adults. This study aimed to describe the epidemiological characteristics and outcomes of pediatric COVID-19 cases in Saudi Arabia in addition to identifying risk factors associated with disease severity. METHODS: This was a multicenter, cross-sectional retrospective study that included confirmed SARS-CoV-2 infection among pediatric patients (< 14 years) from the time of initial identification in March 2020 to the end of July 2020 in 6 centers across the country. Patients were classified based on clinical severity. Study outcomes included time to recovery, need for invasive ventilation, and mortality. Multivariate logistic regression analysis was conducted to explore factors associated with increased disease severity. RESULTS: The study enrolled 567 children with (51.5%) were males, and (44.6%) aged from 6 to 14 years old. Asymptomatic patients accounted for 38.98% of the cases: while 319 patients (56%) had mild disease, and 27 patients (4.76%) had moderate-to-severe disease. Only 10 patients (1.76%) required Pediatric Intensive Care Unit admission. The calculated case-fatality was 0.7%. After performing multivariate regression analysis, chronic lung conditions [adjusted OR = 12.73, 95% CI (2.05-79.12)] and decreased red blood cells (RBCs) count [adjusted OR = 2.43, 95% CI (1.09-5.41] were found to be significant predictors for moderate-to-severe disease (p = 0.006 and 0.030, respectively). CONCLUSION: Most COVID-19 cases in the current study had a benign course of illness and carried an excellent prognosis. Children with chronic lung conditions or low RBCs count are at higher risk to develop moderate-to-severe COVID-19 disease.

Assessing the Accuracy of Different Glucometers Based on the Laboratory Reference Method.

BACKGROUND: Self-monitoring of blood glucose using point-of-care glucometers is a critical tool in diabetic care. Recently, various glucometers have been developed. This cross-sectional study aimed to evaluate the accuracy of commonly used glucometers by comparing their readings with those of the laboratory reference method. METHODS: The five commercially available glucometers - Accu-Chek (Roche Diagnostics GmbH, Mannheim, Ger-many), OneTouch (LifeScan Inc, USA), Freestyle Optium Neo (Abbott Diabetes Care Inc, USA), Contour Next, and Contour Next One (Ascensia Diabetes Care Inc. Canada) - were utilized in our study. Participants were randomly selected for measuring fasting blood glucose levels to eliminate any factors that could affect measurements by the glucometers and glucose hexokinase method (reference method). Statistical analysis was carried out and the readings were expressed as mean and standard deviation. RESULTS: All glucometer readings correlated well with the laboratory measurements; however, the venous glucose level readings showed a slight difference, especially in case of higher blood glucose levels. Although, no significant difference was found between the mean venous blood glucose and the mean of other glucometer readings, a highly significant positive correlation was found between laboratory measurements and glucometer readings. Moreover, our study confirmed that Accu-Check, OneTouch, and FreeStyle Optium Neo meters were significantly useful predictors of venous blood glucose. Notably, Freestyle Optium Neo showed the minimal mean bias (-0.4%) in contrast to Contour Next One that showed the highest proportional bias (6.1%). CONCLUSIONS: Independent comparison of all glucometers should be carried out as the proportional bias, especially in case of high blood glucose levels, can affect patient care.

Prevalence and Predictors of Depression Among Medical Residents in Western Saudi Arabia.

There is evidence of a higher depression rate among resident physicians compared to the general population. This study aimed to estimate the prevalence of depression and assess its severity and predictors among physician residents in Jeddah, Western Saudi Arabia. A cross-sectional survey was conducted using the self-administered Patient Health Questionnaire (PHQ-9). This study included 149 medical residents. More than half (53%) were female and 43% were married. A diagnosis of depression (mild to severe) was identified in 75.8% of the participants (mild in 35.6%, moderate in 34.2%, and severe depression in 6.0%). Residents in surgery and emergency programs were at an increased risk for moderate-to-severe depression (OR 2.60, 95% CI 1.13, 5.98; OR 4.90, 95% CI 1.08, 22.20; respectively). Mental health programs for resident physicians would facilitate the early detection of depression and mental disorders. However, adequate mentoring, managing workloads, and social off-duty activities are always vital.

Prevalence and preventability of sentinel events in Saudi Arabia: analysis of reports from 2012 to 2015.

This study aimed to assess the pattern of sentinel events reported to Ministry of Health of Saudi Arabia from January 2012 to June 2015. Sentinel event reports were examined for patient characteristics, type of event, outcome, cause and preventability. There were 433 sentinel events: 58.2% were deaths, 14.8% were unexpected loss of a limb or a function, 7.4% major medication errors and 7.4% retained instruments or sponges. Among the reported events, 44% were associated with surgical interventions and most were classified as preventable (91.6%). Age 19-64 years was significantly associated with death as an outcome (P = 0.02). Non-preventable sentinel events were significantly more likely among women than men (P = 0.01). Unavailability of policy and procedures and/ or failure to implement them (55%), and lack of proper communication (35%) and training (33%) were the main causes for the adverse events. Efforts should focus on enhancing the National Sentinel Events Reporting System, adopting criteria for effective reporting and ensuring availability and implementation of policies and procedures.

Drug poisoning and associated factors in western Saudi Arabia: A five-year retrospective chart review (2011-2016).

OBJECTIVE: Drug poisoning is a globally common cause of emergency-room admissions. This study explores drug-poisoning prevalence patterns, associated risk factors (gender, age and exposure circumstances), and outcomes in western Saudi Arabia. METHODS: Retrospective analysis of Clinical drug poisoning cases (2011-2016). The data were retrieved from the Saudi Ministry of Health's record and Patients' medical charts were analyzed. RESULTS: The Ministry of Health received 1,474 reports of drug poisoning during 2011-2016. More than half involved females (n=885, 60%) or young children (0-4 years old) (n=764, 51.8%) and occurred accidentally (n=786, 53.3%); almost all had an oral route of poisoning (n=1,466, 99.5%). The cases most frequently involved analgesic and non-steroidal anti-inflammatory drugs (n=373, 25.2%); antiepileptic, antipsychotic, psychoactive, and anxiolytic drugs (n=229, 16.3%); antihistamine, asthma, flu, and cough drugs (n=157, 12.0%); and antibiotic, anti-fungal; and antiprotozoal drugs (n=74, 5.0%). Antidotes were administered in only 2.2% of cases, and no deaths were reported. CONCLUSION: The drug poisoning cases involved females and young children (younger than 5 years old) and the most cases were accidental, and the most commonly used drugs were analgesics (Panadol), followed by antipsychotics, antihistamines, and antiepileptics (Tegretol).

IFN-α2a or IFN-ß1a in combination with ribavirin to treat Middle East respiratory syndrome coronavirus pneumonia: a retrospective study.

OBJECTIVES: Middle East respiratory syndrome coronavirus (MERS-CoV) is associated with significant mortality. We examined the utility of plasma MERS-CoV PCR as a prognostic indicator and compared the efficacies of IFN-α2a and IFN-ß1a when combined with ribavirin in reducing MERS-CoV-related mortality rates. METHODS: We retrospectively analysed 32 patients with confirmed MERS-CoV infection, admitted between April 2014 and June 2014, by positive respiratory sample RT-PCR. Plasma MERS-CoV RT-PCR was performed at the time of diagnosis for 19 patients. RESULTS: The overall mortality rate was 69% (22/32). Ninety percent (9/10) of patients with positive plasma MERS-CoV PCR died compared with 44% (4/9) of those with negative plasma MERS-CoV PCR. Mortality rate in patients who received IFN-α2a was 85% (11/13) compared with 64% (7/11) in those who received IFN-ß1a (P = 0.24). The mortality rate in patients with renal failure (14), including 8 on haemodialysis, was 100%. Age >50 years and diabetes mellitus were found to be significantly associated with mortality (OR = 26.1; 95% CI 3.58-190.76; P = 0.001 and OR = 15.74; 95% CI 2.46-100.67; P = 0.004, respectively). The median duration of viral shedding in patients who recovered was 11 days (range 6-38 days). Absence of fever was noted in 5/32 patients. CONCLUSIONS: Plasma MERS-CoV RT-PCR may serve as an effective tool to predict MERS-CoV-associated mortality. Older age and comorbid conditions may have contributed to the lack of efficacy of IFN-α2a or IFN-ß1a with ribavirin in treating MERS-CoV. Absence of fever should not exclude MERS-CoV.

Pattern of drug overdose and chemical poisoning among patients attending an emergency department, western Saudi Arabia.

Poisoning is a medical emergency that represent a major health problem all over the world. Studies on drug overdose and chemical poisoning are very limited in Saudi Arabia (SA). We aimed to describe the current pattern and assess risk factors of drug overdose and chemical poisoning in King Khalid National Guard hospital, Jeddah, SA. Medical records of patients attended emergency department in King Khalid National Guard hospital during the period from January 2008 to December 2012 due to drug overdose and chemical poisoning were reviewed. A total of 129 cases were included in the study. The majority of the population was Saudi (97.7 %), and almost half of them were females (54.3 %). Children under 12 years were the most affected age group (44.2 %). Drug overdose was the most common cause of poisoning (92.2 %). Analgesics and non-steroidal anti-inflammatory drugs represented the highest percentage of used medications (20.4 %). The most commonly reported symptoms were symptoms of the central nervous system (57.4 %) followed by GIT symptoms (41.9 %). Intentional poisoning was reported in 34 cases (26.4 %). Female patients were significantly more likely to attempt suicide than male patients (OR = 7.22, 95 % CI = 1.70, 30.62). Children continue to be at high risk for medication and chemical poisoning. Accessibility to medications at homes encountered for most of poisoning cases among children. Implementing methods to raise public awareness and minimize children access to medications would significantly contribute to reducing burden of this problem on the community.

Knowledge and practices of healthcare workers in relation to bloodborne pathogens in a tertiary care hospital, Western Saudi Arabia.

To assess knowledge and practices of healthcare workers (HCWs) in relation to bloodborne pathogens in a tertiary care hospital, western Saudi Arabia. Self-administered questionnaire was distributed assessing demographic characteristics, knowledge and practices of physicians, nurses and technicians on risks of exposure and prophylaxis against human immunodeficiency virus, hepatitis B virus and hepatitis C virus infections. A total of 466 participants (151; 32.4 % physicians and 315; 67.6 % nurses/technicians) completed the questionnaire. Almost two thirds of the physicians (60.9 %) and half of the nurses/technicians (47.6 %) had history of exposure to risks of bloodborne infection. Although both physicians and nurses/technicians showed acceptable level of knowledge about risks of bloodborne infections, modest proportion knew the correct actions including reporting following exposure. Behavioral-based in-service training interventions and strict policy should be implemented to promote compliance of HCWs to the protective measures against hazards of bloodborne infection.

Novel preventive bundle for multidrug-resistant organisms in intensive care setting; tertiary care experience.

Background: A widely-accepted standardized preventive bundle targeting multidrug-resistant organisms (MDROs) is lacking. The objective was to describe the components, implementation, compliance, and impact of a novel MDROs bundle in intensive care units (ICUs). Methods: Cohort study of surveillance activities on the components of MDROs bundle (July 2019 to June 2022) and the incidence of MDROs (April 2016 to June 2022). The implementation of MDROs bundle were preceded by ICPs-led education of the staff working in target ICUs about the importance and components of the MDROs bundle. These included the overall use of antimicrobials, appropriate environmental cleaning, appropriate contact precautions, and hand hygiene compliance. Results: During implementation, the overall use of antimicrobials was 57.8 days of therapy per 100 patient-days (44,492/76,933). It was higher in adult compared with pediatric/neonatal ICUs (p < 0.001). Appropriate environmental cleaning was 74.8% (12,409/16,582), appropriate contact precautions was 83.8% (10,467/12,497), and hand hygiene compliance was 86.9% (27,023/31,096). The three components were significantly higher in pediatric/neonatal compared with adult ICUs (p = 0.027, p < 0.001, p = 0.006, respectively). The MDROs rates per 10,000 patient-days were 71.8 before (April 2016 to June 2019) and 62.0 during (July 2019 to June 2022) the bundle implementation (858/119,565 versus 891/143,649 p = 0.002). The reduction in MDROs rates were replicated in adult (p = 0.001) but not pediatric/neonatal ICUs (p = 0.530). Conclusions: The finding of this study indicate that the implementation of the current bundle was associated with a modest decrease in MDROs rates in adult ICUs. The provided detailed definitions and methodology will facilitate its use by other healthcare facilities.

Improving COVID-19 vaccine uptake: lessons from an academic institution in Saudi Arabia.

Background: Rejection, hesitancy and low uptake of the COVID-19 vaccine are major public health challenges in Saudi Arabia. Aims: To address COVID-19 vaccine hesitancy and rejection at the King Saud Bin Abdulaziz University for Health Sciences (KSAU-HS) using evidence-based strategies. Methods: A questionnaire was administered electronically to participants at KSAU-HS to understand the reasons for vaccine hesitancy or rejection and develop an evidence-informed vaccination plan. Initial results from March 2021 showed that only 60% of respondents had taken at least 1 COVID-19 vaccine dose. Based on the results of the survey, KSAU-HS designed a 6-month vaccination campaign to raise awareness about the vaccine and its importance and increase acceptability rates. Mass media, social media, and direct messaging as reminders were used to address the barriers identified and to help the university community overcome fears and misconceptions about the COVID-19 vaccine. Results: The evidence-based interventions helped achieve a significantly high vaccination rate in the university community, with 99.7% of individuals vaccinated by October 2021; one of the highest vaccination rates among public universities in Saudi Arabia. Conclusion: Evidence-based interventions targeted at specific populations can help address prevailing concerns about the COVID-19 vaccine and other similar public health issues.

Bloodstream gram-negative bacterial infections in adult patients with leukemia: A retrospective review of medical records in a tertiary care hospital in Western Saudi Arabia.

BACKGROUND: Patients with neutropenic cancers are at high risk of acquiring infections, especially if on chemotherapy. Gram-negative bacterial infections are associated with high mortality. This study aimed to assess clinical characteristics, outcomes, and epidemiology of gram-negative bacterial (GNB) bloodstream infections (BSI) in adult patients with leukemia. METHODS: This single-center, retrospective study included 102 adult patients diagnosed with leukemia between 2017 and 2019. The patients' demographics, infection diagnosis, leukemia diagnosis, comorbidities, and infection outcomes were collected from electronic medical records. RESULTS: The most common GNB were Klebsiella pneumoniae (33.3 %), Pseudomonas aeruginosa (23.5 %), and Escherichia coli (17.6 %). Additionally, 36.7 % of infections were multidrug resistant. The most common comorbidities were cardiovascular diseases (36.7 %), diabetes mellitus (33.3 %), and liver diseases (24.1 %). GNB-infected patients had a higher mortality than noninfected patients (35.3 % and 11.8 %, respectively, p = 0.005). In a multivariable analysis, patients with acute myeloid leukemia and acute lymphoid leukemia were significantly more likely to acquire GNB BSI (p = 0.01), while patients with chronic myelogenous leukemia and chronic lymphocytic leukemia had a lower likelihood of developing GNB BSI. In addition, low hemoglobin level was an independent risk factor of GNB BSI (p = 0.001). Chemotherapeutic agents showed an association with increased risk of GNB BSI. CONCLUSIONS: Patients with acute leukemia and low hemoglobin levels have increased risk of GNB BSI, which was associated with increased mortality. Prospective studies are needed to further assess the effect of co-morbidities and chemotherapy medications on the occurrence of GNB BSI according to the type of leukemia.

Risk Factors for Infection With Multidrug-Resistant Gram-Negative Bacteria in a Tertiary Care Hospital in Saudi Arabia: A Case-Control Study.

Background The increase in the incidence of multidrug-resistant (MDR) organisms especially Gram-negative bacteria (GNB) in healthcare facilities is a serious cause of concern. This study identified risk factors for the infection with these MDR GNB, such as Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Escherichia coli to inform healthcare workers about strategies for their containment. Methods A case-control study was carried out at a tertiary care hospital where 100 patients with healthcare-associated infections (infections arising 48 hours after admission) caused by MDR GNB were compared with two control groups, i.e., 100 patients with healthcare-associated infections caused by non-MDR GNB (not meeting the criteria of MDR) and 100 patients without infection caused by GNB. MDR bacteria were defined as the ones that were non-susceptible to at least one antibiotic in three or more classes of antibiotics. The data were analyzed using descriptive statistics (frequency and percentage of categorical variables). Multivariate regression analysis was undertaken to identify significant predictors of MDR GNB. Odds ratios with 95% confidence intervals were calculated, and the level of significance was determined at p-value < 0.05. Results A total of 388 organisms were isolated during four months (January-April 2015) from 332 patients. Fifty-six (17%) of the patients were infected with more than one organism. Among the MDR bacteria, the most dominant MDR organism was A. baumannii (38%), followed by K. pneumoniae (31%), P. aeruginosa (20%), and E. coli (11%). Among the non-MDR organisms, the most dominant was P. aeruginosa (47%), followed by E. coli (32%), K. pneumoniae (18%), and A. baumannii (3%). Patients with MDR organisms compared with the first control group (patients with non-MDR organisms) showed that prior antibiotic use (p-value: 0.001), intensive care unit (ICU) admission (p-value: 0.001), and indwelling medical devices (p-value: 0.005) were significant risk factors for MDR infections. It was also found that the risk factors for MDR GNB infection were the same in the second control group (patients without infection): prior antibiotic use (p-value: 0.002), ICU admission (p-value: 0.001), and indwelling medical devices (p-value: 0.03). Based on the comparison of the two control groups, prolonged hospital stays of more than five days (p-value: 0.001), immunosuppressive therapy (p-value: 0.02), and over 60 years of age (p-value: 0.02) were significant risk factors for non-MDR infection. Conclusion  The risk factors identified in our study provide guidance to healthcare workers for the prevention and containment of MDR GNB.

Prevalence of Myopia and Its Associated Risk Factors Among Children Attending a Tertiary Hospital in Saudi Arabia.

CLINICAL RELEVANCE: This study serves as a tool for optometrists and ophthalmologists to reinforce adherence to several preventive factors, which may decrease the incidence of myopia, and avoidance of risk factors by multiple means including education during hospital visits. It also provides insight into who should be screened and tailored screening programs for children. BACKGROUND: While studies assessing the prevalence of myopia in Saudi Arabia have contradicting results, only a few studies have evaluated the risk factors of myopia and the effect of using electronic devices on its occurrence. Thus, this study aimed to determine the prevalence of myopia and associated risk factors, among children attending an ophthalmology clinic in King Abdulaziz Medical City, Jeddah, Saudi Arabia. METHODS:  A cross-sectional study was conducted. A total of 182 patients aged < 14 years were selected using convenient sampling. Direct assessment of the refraction was performed in the clinic, and a questionnaire was completed by the child's parent. RESULTS: Of 182 patients who met the inclusion criteria, 40.7% had myopia. Myopia was more common in boys (56.8%) than in girls (43.2%), with a median age of 8.7 years. Using multivariate regression analysis, only age (eight years and above) (OR=2.15, CI=1.12-4.12, P= 0.03), and family history of myopia (OR= 5.83, CI= 2.82-12.05, P= 0.001) were significant predictors of myopia in children. Other variables (e.g., sex, and use of laptops, computers, smartphones/tablets, or TV) were not statistically significant. CONCLUSIONS: This study did not show a statistically significant association between using electronic devices and the onset and progression of myopia among children. Studies with a larger sample size are required to further investigate this association and assess other potential risk factors.

Evidence-Based Interventions to Reduce the Incidence of Common Multidrug-Resistant Gram-Negative Bacteria in an Adult Intensive Care Unit.

Background Multidrug-resistant Gram-negative bacteria (MDR-GNB) present a significant and escalating hazard to healthcare globally. Context-specific interventions have been implemented for the prevention and control of MDR-GNB in several healthcare facilities. The objective of this study was to implement and evaluate the effectiveness of evidence-based interventions in the incidence and dissemination of MDR-GNB. Methods This was a pre-and post-intervention study conducted in three phases at King Abdulaziz Medical City Jeddah, Saudi Arabia. During Phase-1, the data on each of the four MDR-GNB (Acinetobacter baumannii, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Escherichia coli) were collected prospectively. Genomic fingerprinting was performed on isolates using enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR) to determine clonality and establish a link between different strains within and between the hospital wards/units. In the second phase, targeted interventions were implemented in the adult intensive care unit (ICU) based on previously determined risk factors and included the education of healthcare workers on hand hygiene, disinfection of patients' surrounding, daily chlorhexidine baths, and disinfection rooms on discharge with hydrogen peroxide fogging after MDR-GNB patients were discharged. An antibiotic restriction protocol was simultaneously implemented as part of the hospital antibiotic stewardship program. In the third phase, the effectiveness of the interventions was evaluated by comparing the incidence rate and clonality (using ERIC-PCR genetic fingerprints) of MDR-GNB before and after the intervention. Results A significant reduction of MDR-GNB was observed in Phase-2 and Phase-3 compared with Phase-1. The mean incidence rate of MDR-GNB per 1000 patient days in Phase-1 (pre-intervention) was 11.08/1000, followed by 6.07 and 3.54/1000 in Phase-2 and Phase-3, respectively. A statistically significant reduction was observed in the incidence rate of MDR-GNB in the adult ICU (P=0.007), whereas no statistically significant decrease (P=0.419) was observed in areas other than the adult ICU. Two A. baumannii strains appear to be circulating within the ICU environment with reduced frequency in Phase-2 and Phase-3 compared to Phase-1. Conclusion  There was a significant reduction in the incidence of MDR-GNB in the adult ICU due to the successful implementation of both infection control and stewardship interventions, albeit challenging to ascertain the relative contribution of each.

Contributions of inhalation and dermal exposure to chlorpyrifos dose in Egyptian cotton field workers.

OBJECTIVE: Chlorpyrifos exposures were assessed in 12 Egyptian cotton field workers. METHODS: 3,5,6-trichloro-2-pyridinol (TCPy) was measured in 24-hour urine samples to estimate absorbed dose. Workshift air samples were used to calculate chlorpyrifos inhalation dose. RESULTS: Patches on legs had the highest chlorpyrifos loading rates among body regions sampled. Geometric mean chlorpyrifos air concentrations were 5·1, 8·2, and 45·0 µg/m(3) for engineers, technicians, and applicators, respectively; peak TCPy urinary concentrations were 75-129, 78-261, and 487-1659 µg/l, respectively; geometric mean doses were 5·2-5·4, 8·6-9·7, and 50-57 µg/kg, respectively, considering TCPy excretion half-life values of 27 and 41 hours. All worker doses exceeded the acceptable operator exposure level of 1·5 µg/kg/day. An estimated 94-96% of the dose was attributed to dermal exposure, calculated as the difference between total dose and inhalation dose. DISCUSSION: Interventions to reduce dermal exposure are warranted in this population, particularly for the hands, feet, and legs.

Meningococcal Disease and Immunization Activities in Hajj and Umrah Pilgrimage: a review.

Invasive meningococcal disease (IMD) outbreaks associated with Hajj and Umrah pilgrimage events in the Kingdom of Saudi Arabia (KSA) are well recognized. Past outbreaks have been associated with substantial intercontinental spread of specific Neisseria meningitidis serogroups. The emergence of meningococcal serogroup W (MenW) was a global concern following the 2000/2001 Hajj outbreaks. Broader compulsory meningococcal serogroups A, C, W and Y (MenACWY) immunization strategies for pilgrims were introduced in response to these events and led to substantial declines in IMD cases associated with these mass gatherings. However, there remains potential for future outbreaks either within KSA during the Hajj or in local populations via pilgrim meningococcal transmission on their return. While the annual Hajj involves pilgrims from over 185 countries, two-thirds of these arrive from 13 countries, chiefly from across South-East Asia, the Middle East and North African (MENA) regions; for which we review the relevant epidemiology of IMD and meningococcal carriage. While disease surveillance is limited and data are often lacking, MenB is an important serogroup associated with IMD and carriage in a number of countries. Available literature suggests that most pilgrims receive polysaccharide MenACWY vaccines (which do not impact carriage and onward transmission) and incomplete compliance with visa/entry immunization regulations is reported. Existing preventative approaches for visiting pilgrims require continued oversight. More complete compliance and switching to the conjugated MenACWY vaccine can provide more robust and broader protection for pilgrims. Additional immunization options could also be considered.

Assessing the Effectiveness of Antibiotic Therapy Against Common Gram-Negative Bacteria in a Saudi Arabian Hospital Using the Drug Resistance Index.

INTRODUCTION: Assessing the effectiveness of antibiotics and communicating the problem of resistance are essential when devising antimicrobial stewardship programs (ASPs) in hospital settings. The Drug Resistance Index (DRI) is a useful tool that combines antibiotic consumption and bacterial resistance into a single measure. In this study, we used the DRI to assess the impact of introducing a new antibiotic restriction form on antibiotic effectiveness for the treatment of Gram-negative infections in the intensive care unit (ICU). METHODS: This was an observational study to assess and evaluate the antibiotic susceptibility of Gram-negative bacteria and antibiotic prescribing rates for the antibiotics indicated for Gram-negative bacteria following the introduction of a new antibiotic restriction form. The study was conducted from 2015 to 2017 at King Abdulaziz Medical City, a tertiary care facility in Jeddah, Saudi Arabia. Changes in antibiotic effectiveness before and after the introduction of the form were evaluated by calculating the DRI for four of the most common Gram-negative pathogens and eight commonly used antibiotic classes. RESULTS: The overall DRI for the adult ICU was higher (59.45) in comparison to the hospital-wide DRI (47.96). A higher DRI was evident for carbapenems and antipseudomonal penicillins + beta-lactamase inhibitors. Acinetobacter baumannii had the highest DRI followed by Klebsiella pneumoniae in both the adult ICU and hospital-wide. After the implementation of antibiotic restriction in the adult ICU, the DRI for carbapenems was significantly lower in the post-intervention phase (from 31.61 to 26.05) (p = 0.031). CONCLUSION: The DRI is a useful tool for tracking the effectiveness of antibiotics over time. The results of our study are significant in the way that it highlights the importance of having an effective antibiotic stewardship program in healthcare settings and regular feedback of antibiotic consumption data to the stakeholders to keep the antibiotic prescriptions in check, thereby ensuring their sustained effectiveness.

The Incidence of Respiratory Infections and Risk Factors Among Cancer Patients Undergoing Chemotherapy at a Tertiary Care Hospital in Western Saudi Arabia.

Introduction Cancer patients receiving chemotherapy are prone to infections because of the treatment regimens' immunosuppression.  Objectives This study estimated the overall incidence of respiratory infections among patients undergoing chemotherapy and associated risk factors. Methods This study is a retrospective chart review of cancer patients at Princess Noorah Oncology Center in Western Saudi Arabia from January 2017 to December 2020.  Results This study included 196 patients, 53.1% males and 50.5% older than 50 years. The estimated incidence of respiratory infections among participants was 8.7%, and the most commonly detected organism was Klebsiella pneumoniae (35.3%). The risk factors significantly associated with infection were ICU admission (p=0.001), the use of mechanical ventilation (p=0.003), and the presence of hematologic malignancy (p=0.02). Conclusion Future multi-center studies should employ a prospective design, including laboratory confirmation of causative organisms. Such studies may better estimate the infection-associated burden on cancer patients undergoing chemotherapy.

Quality of care provided to diabetic patients attending primary health care centers in National Guard in Makkah Region, Saudi Arabia.

Background: Diabetes is a costly and serious health problem that is increasing markedly. The quality of care is a major issue among diabetic patients. This study aims to assess the quality of care provided to diabetic patients using the American Diabetes Association (ADA) indicators. Methods: This was a cross-sectional study conducted using a retrospective chart review. The population was adult diabetic patients (type 2) who had attended the National Guard's primary healthcare centers, Makkah region, Saudi Arabia, from January 1, 2017, to December 31, 2018. Results: We studied 400 adult diabetic patients aged 30-97 years with a mean age of 58.25 (SD = 11.9). The length of time with diabetes ranged from 1 to 42 years with a mean of 9.66 years (SD = 7.6). Among all the primary healthcare centers (PHCs), specialized polyclinic (SPC) had the highest number of patient visits. Furthermore, the SPC had the highest number of patients with complications; the primary healthcare center with the fewest complications was Iskan-Jeddah. The results show that the control of hemoglobin A1C (HbA1C) was better in 2018 than in 2017. Conclusion: There is improved and adequate care provided to patients among the assessed primary healthcare centers in the Makkah region. Nevertheless, there remains a need for interventions to maintain comprehensive data on diabetes performance. Monitoring and proper education on diabetic care to patients are suggested to achieve better control of diabetes and delay the occurrence of complications.

Evaluation of ceftazidime/avibactam for treatment of carbapenemase-producing carbapenem-resistant Enterobacterales with OXA-48 and/or NDM genes with or without combination therapy.

Background: Carbapenem-resistant Enterobacterales (CRE) is an urgent public health threat of significant global concern. Few observational studies have evaluated the clinical outcomes for treatment of CRE harbouring OXA-48 or NDM genes with ceftazidime/avibactam. Previous findings showed lower 30 day mortality with ceftazidime/avibactam ranges between 8.3% and 22%. Method: This single-centre retrospective cohort study included adult patients aged ≥18 years admitted to King Abdulaziz Medical City (KAMC) who had received ceftazidime/avibactam for at least 72 h for infections caused by CRE with genes encoding for carbapenemase production (CP-CRE). Results: A total of 211 patients, mostly male (57%), having CP-CRE infections treated with ceftazidime/avibactam were included, with an average age of 62 years. More than 50% of patients were critically ill, for which 46% received invasive ventilation and 36% were on inotropes. The most frequent infectious disease was hospital/ventilator-acquired pneumonia with Klebsiella pneumoniae being the most frequent causative pathogen. The majority of isolates harboured OXA-48 (81%), followed by NDM ±â€ŠOXA-48 (19%). The overall clinical cure and 30 day mortality was 78% and 21% respectively (stratified per gene: 79% and 21.6% for OXA-48 and 75% and 17.5% for NDM ±â€ŠOXA-48). Conclusions: This was the largest study that evaluated clinical outcomes associate with CP-CRE harbouring OXA-48 gene infections treated with ceftazidime/avibactam. Clinical cure and 30 day mortality were consistent with those of previous studies. Findings suggested that combination therapy with ceftazidime/avibactam had no direct impact on clinical outcomes for CP-CRE with OXA-48.
