Over-Prescription and Overuse of Antimicrobials in the Eastern Mediterranean Region: The Urgent Need for Antimicrobial Stewardship Programs with Access, Watch, and Reserve Adoption

Excessive antimicrobial use contributes to the development of antimicrobial resistance. In the Eastern Mediterranean region (EMR), there is dearth of information on the prevalence of antimicrobial use in patients hospitalized in acute healthcare settings, clinical indications, types of antimicrobials prescribed, and quality indicators for prescriptions. Between September and December 2019, seven countries in the EMR conducted a standardized point prevalence survey. All patients present in the hospital wards at 8 a.m. on the day of the survey constituted the sample population. We collected data, including patient characteristics, antimicrobials received, therapeutic indication according to predefined lists, and markers of prescribing quality. The survey included data from 139 hospitals in seven countries. Among the 19,611 inpatients surveyed, 11,168 patients received at least one antimicrobial {crude prevalence: 56.9% (95%CI: 56.2-57.6%). The top three classes of antimicrobials prescribed were third-generation cephalosporins (26.7%), beta-lactam penicillins (18.1%), and imidazole derivatives (n = 1655, 9.8%). Carbapenems were most frequently prescribed for the treatment of healthcare-associated infections. Compliance with quality indicators of antimicrobial use was limited where treatment guidelines were available for 41% of antimicrobial prescriptions and targeted antimicrobial treatment represented 21% of therapeutic indications. Overall hospital antimicrobial use was high in countries of the EMR, pointing to the need to design and implement context-specific antimicrobial stewardship programs to optimize antimicrobial use and reduce antimicrobial resistance.

Infection prevention and control risk factors in health workers infected with SARS-CoV-2 in Jordan: A case control study

Background

Despite under-reporting, health workers (HWs) accounted for 2 to 30% of the reported COVID-19 cases worldwide. In line with data from other countries, Jordan recorded multiple case surges among HWs.

Methods

Based on the standardized WHO UNITY case-control study protocol on assessing risk factors for SARS-CoV-2 infection in HWs, HWs with confirmed COVID-19 were recruited as cases from eight hospitals in Jordan. HWs exposed to COVID-19 patients in the same setting but without infection were recruited as controls. The study lasted approximately two months (from early January to early March 2021). Regression models were used to analyse exposure risk factors for SARS-CoV-2 infection in HWs; conditional logistic regressions were utilized to estimate odds ratios (ORs) adjusted for the confounding variables.

Results

A total of 358 (102 cases and 256 controls) participants were included in the analysis. The multivariate analysis showed that being exposed to COVID-19 patients within 1 metre for more than 15 minutes increased three-fold the odds of infection (OR 2.92, 95% CI 1.25–6.86). Following IPC standard precautions when in contact with patients was a significant protective factor. The multivariate analysis showed that suboptimal adherence to hand hygiene increased the odds of infection by three times (OR 3.18; 95% CI 1.25–8.08).

Conclusion

Study findings confirmed the role of hand hygiene as one of the most cost-effective measures to combat the spreading of viral infections. Future studies based on the same protocol will enable additional interpretations and confirmation of the Jordan experience.

Increasing Antimicrobial Resistance in World Health Organization Eastern Mediterranean Region, 2017–2019

To better guide the regional response to antimicrobial resistance (AMR), we report the burden of AMR over time in countries in the World Health Organization Eastern Mediterranean Region. To assess the capacities of national infection prevention and control and antimicrobial stewardship programs, we analyzed data on bloodstream infections reported to the Global Antimicrobial Resistance Surveillance System during 2017–2019, data from 7 countries on nationally representative surveys of antimicrobial prescriptions, and data from 2 regional surveys. The median proportion of bloodstream infections was highest for carbapenem-resistant Acinetobacter spp. (70.3%) and lowest for carbapenem-resistant Escherichia coli (4.6%). Results of the regional assessments indicate that few countries have capacities for infection prevention and control and antimicrobial stewardship programs to prevent emergence and spread of AMR. Overall, the magnitude of the problem and the limited capacity to respond emphasize the need for regional political leadership in addressing AMR.

A theory-based exploration of antibiotic use in primary healthcare in Gezira state, Sudan

BACKGROUND

Inappropriate use of antibiotics is a major contributing factor to the emergence of antimicrobial resistance globally, including in Sudan.

OBJECTIVES

The project aimed to develop a theory-driven behaviour change strategy addressing both prescribers and patients based on factors that are driving antibiotic use in primary healthcare settings in Gezira state in Sudan.

METHODS

The strategy was designed based on the Theoretical Domains Framework (TDF) to identify behavioural domains and the Behaviour Change Wheel (BCW) to select appropriate intervention functions. The process included (1) a formative qualitative research study and (2) a knowledge co-production workshop that utilized the results of the qualitative study to design a salient, appropriate, and credible behaviour change strategy.

RESULTS

The TDF domains related to prescribers that emerged from the study included knowledge, skills, and intention. The selected BCW intervention functions included education, training, modelling, and persuasion. The main TDF domains related to patients included social influences and intention. The selected BCW intervention functions included enablement and education.

CONCLUSION

Using the TDF and BCW intervention functions, the study identified behavioural domains that influence antibiotic prescription and consumption in rural primary healthcare settings in Gezira state in Sudan and appropriate intervention functions to modify these behaviours. Knowledge co-production ensured that the evidence-based strategy was acceptable and practical in the local context.

Developing a theory-based behavior change intervention to improve the prescription of surgical prophylaxis

Background Antimicrobial resistance (AMR) is increasingly pervasive due to multiple, complex prescribing and consuming behaviours. Accordingly, behaviour change is an important component of response to AMR. Little is known about the best approaches to change antibiotic use practices and behaviours. Aim This project aims to develop a context-specific behaviour change strategy focusing on promoting appropriate prescription practices following the World Health Organization recommendations for surgical prophylaxis in an orthopaedic surgery unit in Egypt. Method The project included a formative qualitative research study with 31 in-depth interviews with orthopaedic surgeons that was based on the Theoretical Domains Framework (TDF) and an intervention that was developed to following the Behaviour Change Wheel (BCW) in a knowledge co-production workshop with ten public health experts that ensured that the theory based intervention was a culturally acceptable, practical and implementable intervention. Results The prescription of surgical prophylaxis was influenced by eight TDF domains from which workshop participants selected five to be included in the behaviour change intervention including, knowledge, belief in consequences (mistrust towards infection prevention and control measures), environmental factors (lack of prescription guidelines), professional role and reinforcement (a lack of appropriate follow up actions influenced prescription of surgical prophylaxis). The appropriate set of behaviour change functions of BCW and related activities to improve the current practices included education, enablement, persuasion, environmental restructuring and restriction. Conclusion The study showed that a theory based, and context specific intervention can be created by using the TDF and BCW together with knowledge-co creation to improve the prescription of surgical prophylaxis in and Egyptian orthopaedic unit. The intervention needs to piloted and scaled up.

Epidemiology of Carbapenem-resistant Enterobacteriaceae in Egyptian intensive care units using National Healthcare-associated Infections Surveillance Data, 2011-2017

Objective

To describe the epidemiology of carbapenem-resistant Enterobacteriaceae (CRE) healthcare-associated infections (HAI) in Egyptian hospitals reporting to the national HAI surveillance system.

Methods

Design: Descriptive analysis of CRE HAIs and retrospective observational cohort study using national HAI surveillance data. Setting: Egyptian hospitals participating in the HAI surveillance system. The patient population included patients admitted to the intensive care unit (ICU) in participating hospitals. Enterobacteriaceae HAI cases were Klebsiella, Escherichia coli, and Enterobacter isolates from blood, urine, wound or respiratory specimen collected on or after day 3 of ICU admission. CRE HAI cases were those resistant to at least one carbapenem. For CRE HAI cases reported during 2011-2017, a hospital-level and patient-level analysis were conducted using only the first CRE isolate by pathogen and specimen type for each patient. For facility, microbiology, and clinical characteristics, frequencies and means were calculated among CRE HAI cases and compared with carbapenem-susceptible Enterobacteriaceae HAI cases through univariate and multivariate logistic regression using STATA 13.

Results

There were 1598 Enterobacteriaceae HAI cases, of which 871 (54.1%) were carbapenem resistant. The multivariate regression analysis demonstrated that carbapenem resistance was associated with specimen type, pathogen, location prior to admission, and length of ICU stay. Between 2011 and 2017, there was an increase in the proportion of Enterobacteriaceae HAI cases due to CRE (p-value = 0.003) and the incidence of CRE HAIs (p-value = 0.09).

Conclusions

This analysis demonstrated a high and increasing burden of CRE in Egyptian hospitals, highlighting the importance of enhancing infection prevention and control (IPC) programs and antimicrobial stewardship activities and guiding the implementation of targeted IPC measures to contain CRE in Egyptian ICU's .

An educational intervention to promote appropriate antibiotic use for acute respiratory infections in a district in Egypt- pilot study

Background

Antibiotic overuse is the most important modifiable factor contributing to antibiotic resistance. We conducted an educational campaign in Minya, Egypt targeting prescribers and the public through communications focused on appropriate antibiotic use for acute respiratory infections (ARIs).

Methods

The entire population of Minya was targeted by the campaign. Physicians and pharmacists were invited to participate in the pre-intervention assessments. Acute care hospitals and a sample of primary healthcare centers in Minya were randomly selected for a pre-intervention survey and all patients exiting outpatient clinics on the day of the survey were invited to participate. The same survey methodology was conducted for the post-intervention assessments. Descriptive comparisons were made through three assessments conducted pre- and post-intervention. We quantitated antibiotic prescribing through a survey administered to patients with an ARI exiting outpatient clinics. Additionally, physicians, pharmacists, and patients were interviewed regarding their attitudes and beliefs towards antibiotic prescribing. Finally, physicians were tested on three clinical scenarios (cold, bronchitis, and sinusitis) to measure their knowledge on antibiotic use.

Results

Post-intervention patient exit surveys revealed a 23.1% decrease in antibiotic prescribing for ARIs in this population (83.7 to 64.4%) and physicians and pharmacists self-reported less frequently prescribing antibiotics for ARIs on their follow-up surveys. We also found an increase in correct responses to the clinical scenarios and in attitude and belief scores for physicians, pharmacists, and patients regarding antibiotic use in the post-intervention sample.

Conclusions

Overall, the samples surveyed after the community-based educational campaign reported a lower frequency of antibiotic prescribing and improved knowledge and attitudes regarding antibiotic misuse compared to the samples surveyed before the campaign. Ongoing interventions educating providers and patients are needed to decrease antibiotic misuse and reduce the spread of antibiotic resistance in Egypt.

Evidence of sustained reductions in the relative risk of acute hepatitis B and C virus infections, and the increasing burden of hepatitis a virus infection in Egypt: comparison of sentinel acute viral hepatitis surveillance results, 2001-17

BACKGROUND

Egypt ranks fifth for the burden of viral hepatitis worldwide. As part of Egypt's renewed national strategy for the elimination of viral hepatitis, surveillance for acute viral hepatitis (AVH) was re-established during 2014-2017 to describe the current epidemiology and associated risk factors, and changes from surveillance conducted during 2001-2004.

METHODS

Patients with suspected AVH were enrolled, completed a questionnaire, and provided blood for testing for hepatitis viruses A (HAV), B (HBV), C (HCV), D, and E (HEV) infections by enzyme-linked immunosorbent assay. Odds ratios and Chi2 were used to detect differences between hepatitis types by patient characteristics and exposures. Newcombe-Wilson method was used to compare results between surveillance periods 2001-2004 and 2014-2017.

RESULTS

Between 2014 and 2017, among 9321 patients enrolled, 8362 (89.7%) had one or more markers of AVH including 7806 (93.4%) HAV, 252 (3.0%) HCV, 238 (2.8%) HBV, and 31 (0.4%) HEV infection. HAV infection occurred most commonly among children < 16 years age, while HBV infection occurred among ages 16-35 years and HCV infection in ages greater than 45 years. Healthcare-associated exposures were significantly associated with HBV and HCV infections compared to HAV infection including receiving therapeutic injections, surgery, wound suture, or urinary catheter and IV line insertions, while significant lifestyle exposures included exposure to blood outside the healthcare system, IV drug use, or incarceration. Exposures significantly associated with HAV infection were attending nursery or pre-school, contact with person attending nursery or pre-school, having meals outside the home, or contact with HAV case. Compared with AVH surveillance during 2001-2004, there was a significant increase in the proportion of HAV infections from 40.2 to 89.7% (RR = 2.3) with corresponding reductions in the proportions of HBV and HCV infections from 30.0 to 2.8% (RR = 0.1) and 29.8 to 3.0% (RR = 0.1), respectively.

CONCLUSIONS

Healthcare-associated exposures were significantly association with and remain the greatest risk for HBV and HCV infections in Egypt. Additional studies to evaluate factors associated with the reductions in HBV and HCV infections, and cost effectiveness of routine HAV immunization might help Egypt guide and evaluate control measures.

Viral etiology, seasonality and severity of hospitalized patients with severe acute respiratory infections in the Eastern Mediterranean Region, 2007-2014

Introduction

Little is known about the role of viral respiratory pathogens in the etiology, seasonality or severity of severe acute respiratory infections (SARI) in the Eastern Mediterranean Region.

Methods

Sentinel surveillance for SARI was conducted from December 2007 through February 2014 at 20 hospitals in Egypt, Jordan, Oman, Qatar and Yemen. Nasopharyngeal and oropharyngeal swabs were collected from hospitalized patients meeting SARI case definitions and were analyzed for infection with influenza, respiratory syncytial virus (RSV), adenovirus (AdV), human metapneumovirus (hMPV) and human parainfluenza virus types 1–3 (hPIV1-3). We analyzed surveillance data to calculate positivity rates for viral respiratory pathogens, describe the seasonality of those pathogens and determine which pathogens were responsible for more severe outcomes requiring ventilation and/or intensive care and/or resulting in death.

Results

At least one viral respiratory pathogen was detected in 8,753/28,508 (30.7%) samples tested for at least one pathogen and 3,497/9,315 (37.5%) of samples tested for all pathogens–influenza in 3,345/28,438 (11.8%), RSV in 3,942/24,503 (16.1%), AdV in 923/9,402 (9.8%), hMPV in 617/9,384 (6.6%), hPIV1 in 159/9,402 (1.7%), hPIV2 in 85/9,402 (0.9%) and hPIV3 in 365/9,402 (3.9%). Multiple pathogens were identified in 501/9,316 (5.4%) participants tested for all pathogens. Monthly variation, indicating seasonal differences in levels of infection, was observed for all pathogens. Participants with hMPV infections and participants less than five years of age were significantly less likely than participants not infected with hMPV and those older than five years of age, respectively, to experience a severe outcome, while participants with a pre-existing chronic disease were at increased risk of a severe outcome, compared to those with no reported pre-existing chronic disease.

Conclusions

Viral respiratory pathogens are common among SARI patients in the Eastern Mediterranean Region. Ongoing surveillance is important to monitor changes in the etiology, seasonality and severity of pathogens of interest.

The prevalence of hepatitis C virus infection in Egypt 2015: implications for future policy on prevention and treatment

BACKGROUND & AIMS

In 2015, a national Egyptian health issue survey was conducted to describe the prevalence of hepatitis C virus (HCV) infection. In this paper, we describe the HCV burden in 2015, compare the results with the national survey conducted in 2008, and discuss the implications of the new findings on prevention of HCV in Egypt.

METHODS

A multistage probability sampling approach was used, similar to the national demographic survey conducted in 2008. More than 90% of sampled individuals complied with the interview and provided blood samples.

RESULTS

In the 15-59-year age groups, the prevalence of HCV antibody was found to be 10.0% (95% CI 9.5-10.5) and that of HCV RNA to be 7.0% (95% CI 6.6-7.4). In children, 1-14 years old, the prevalence of HCV antibody and HCV RNA were 0.4% (95% CI 0.3-0.5) and 0.2% (95% CI 0.1-0.3) respectively. Approximately, 3.7 million persons have chronic HCV infection in the age group 15-59 in 2015. An estimated 29% reduction in HCV RNA prevalence has been seen since 2008, which is largely attributable to the ageing of the group infected 40-50 years ago during the mass schistosomiasis treatment campaigns. Prevention efforts may have also contributed to this decline, with an estimated 75% (95% CI 6-45) decrease in HCV incidence in the 0-19 year age groups over the past 20 years.

CONCLUSIONS

These findings can be used to shape future HCV prevention policies in Egypt.

National surveillance of health care-associated infections in Egypt: Developing a sustainable program in a resource-limited country

BACKGROUND

Health care-associated infections (HAIs) are a major global public health concern. The lack of surveillance systems in developing countries leads to an underestimation of the global burden of HAI. We describe the process of developing a national HAI surveillance program and the magnitude of HAI rates in Egypt.

METHODS

The detailed process of implementation of a national HAI surveillance program is described. A 3-phase surveillance approach was implemented in intensive care units (ICUs). This article focuses on results from the phase 2 surveillance. Standard surveillance definitions were used, clinical samples were processed by the hospital laboratories, and results were confirmed by a reference laboratory.

RESULTS

Ninety-one ICUs in 28 hospitals contributed to 474,544 patient days and 2,688 HAIs. Of these, 30% were bloodstream infections, 29% were surgical site infections, 26% were pneumonia, and 15% were urinary tract infections. Ventilator-associated pneumonia had the highest incidence of device-associated infections (4.3/1,000 ventilator days). The most common pathogens reported were Klebsiella spp (28.7%) and Acinetobacter spp (13.7%). Of the Acinetobacter spp, 92.8% (157/169) were multidrug resistant, whereas 42.5% (151/355) of the Klebsiella spp and 54% (47/87) of Escherichia coli were extended-spectrum β-lactamase producers.

CONCLUSIONS

Implementation of a sustainable surveillance system in a resource-limited country was possible following a stepwise approach with continuous evaluation. Enhancing infection prevention and control programs should be an infection control priority in Egypt.

Morbidity, Mortality, and Seasonality of Influenza Hospitalizations in Egypt, November 2007-November 2014

BACKGROUND

Influenza typically comprises a substantial portion of acute respiratory infections, a leading cause of mortality worldwide. However, influenza epidemiology data are lacking in Egypt. We describe seven years of Egypt's influenza hospitalizations from a multi-site influenza surveillance system.

METHODS

Syndromic case definitions identified individuals with severe acute respiratory infection (SARI) admitted to eight hospitals in Egypt. Standardized demographic and clinical data were collected. Nasopharyngeal and oropharyngeal swabs were tested for influenza using real-time reverse transcription polymerase chain reaction and typed as influenza A or B, and influenza A specimens subtyped.

RESULTS

From November 2007-November 2014, 2,936/17,441 (17%) SARI cases were influenza-positive. Influenza-positive patients were more likely to be older, female, pregnant, and have chronic condition(s) (all p<0.05). Among them, 53 (2%) died, and death was associated with older age, five or more days from symptom onset to hospitalization, chronic condition(s), and influenza A (all p<0.05). An annual seasonal influenza pattern occurred from July-June. Each season, the proportion of the season's influenza-positive cases peaked during November-May (19-41%).

CONCLUSIONS

In Egypt, influenza causes considerable morbidity and mortality and influenza SARI hospitalization patterns mirror those of the Northern Hemisphere. Additional assessment of influenza epidemiology in Egypt may better guide disease control activities and vaccine policy.

Influenza hospitalization epidemiology from a severe acute respiratory infection surveillance system in Jordan, January 2008-February 2014

Background

Acute respiratory infections (ARIs) are a major cause of morbidity and mortality worldwide. Influenza typically contributes substantially to the burden of ARI, but only limited data are available on influenza activity and seasonality in Jordan.

Methods

Syndromic case definitions were used to identify individuals with severe acute respiratory infections (SARI) admitted to four sentinel hospitals in Jordan. Demographic and clinical data were collected. Nasopharyngeal and oropharyngeal swabs were tested for influenza using real‐time reverse transcription polymerase chain reaction and typed as influenza A or B, with influenza A further subtyped.

Results

From January 2008–February 2014, 2891 SARI cases were tested for influenza, and 257 (9%) were positive. While 73% of all SARI cases were under 5 years of age, only 57% of influenza‐positive cases were under 5 years of age. Eight (3%) influenza‐positive cases died. An annual seasonal pattern of influenza activity was observed. The proportion of influenza‐positive cases peaked during November–January (14–42%) in the non‐pandemic years.

Conclusions

Influenza is associated with substantial morbidity and mortality in Jordan. The seasonal pattern of influenza aligns with known Northern Hemisphere seasonality. Further characterization of the clinical and financial burden of influenza in Jordan will be critical in supporting decisions regarding disease control activities.

HIV stigma intervention in a low-HIV prevalence setting: a pilot study in an Egyptian healthcare facility

This pilot study is the first to evaluate stigma-reduction intervention in a healthcare setting in Egypt and in the Middle East and North Africa region. It also contributes to knowledge on how to address stigma in low-HIV prevalence settings. A quasi-experimental study design was used to evaluate the effect of anti-HIV stigma intervention in one hospital in Egypt. A control hospital was selected and matched to the intervention hospital by type, size and location. The intervention focused on HIV-related stigma, infection control and medical ethics. Stigma was measured at baseline and at three months post-intervention. A standardized, 10-point scale was developed to measure stigmatizing attitudes and fear-based stigma among participants. Comparisons of overall and job-stratified stigma scores were made across the intervention and control hospitals, before and after the intervention, using two-sample t-test and multivariate regression analysis. Mean stigma scores did not reveal significant differences between the intervention and control hospitals at baseline. After intervention, the overall value-based and fear-based stigma scores were significantly lower in the intervention hospital compared to the control hospital (2.1 and 1.1 compared to 3.8 and 3.2, respectively; p < .001). Context-specific and culturally appropriate HIV stigma-reduction interventions in low-HIV prevalence settings can reduce fear-based and value-based stigma among physicians and nurses.

The Burden of Influenza-Associated Hospitalizations in Oman, January 2008-June 2013

Introduction

Acute respiratory infections (ARI), including influenza, comprise a leading cause of morbidity and mortality worldwide. Influenza surveillance provides important information to inform policy on influenza control and vaccination. While the epidemiology of influenza has been well characterized in western countries, few data exist on influenza epidemiology in the Eastern Mediterranean Region. We describe the epidemiology of influenza virus in Oman.

Methods

Using syndromic case definitions and protocols, patients from four regional hospitals in Oman were enrolled in a descriptive prospective study to characterize the burden of severe acute respiratory infections (SARI) and influenza. Eligible patients provided demographic information as well as oropharyngeal (OP) and nasopharyngeal (NP) swabs. Specimens were tested for influenza A and influenza B; influenza A viruses were subtyped using RT-PCR.

Results

From January 2008 through June 2013, a total of 5,147 cases were enrolled and tested for influenza. Influenza strains were detected in 8% of cases for whom samples were available. Annual incidence rates ranged from 0.5 to 15.4 cases of influenza-associated SARI per 100,000 population. The median age of influenza patients was 6 years with children 0–2 years accounting for 34% of all influenza-associated hospitalizations. By contrast, the median age of non-influenza SARI cases was 1 year with children 0–2 years comprising 59% of SARI. Compared to non-influenza SARI cases, a greater proportion of influenza cases had pre-existing chronic conditions and underwent ventilation during hospitalization.

Conclusions

Influenza virus is associated with a substantial proportion of SARI in Oman. Influenza in Oman approximately follows northern hemisphere seasonality, with major peaks in October to December and a lesser peak around April. The burden of influenza was greatest in children and the elderly. Future efforts should examine the burden of influenza in other potential risk groups such as pregnant women to inform interventions including targeted vaccination.

Antimicrobial stewardship to optimize the use of antimicrobials for surgical prophylaxis in Egypt: A multicenter pilot intervention study

OBJECTIVE

To measure the impact of an antimicrobial stewardship (AMS) program on the use of antibiotics for surgical prophylaxis at acute care hospitals in Egypt.

METHODS

This was a before-and-after intervention study conducted in 5 tertiary, acute-care surgical hospitals. The baseline, intervention, and follow-up periods were 3, 6, and 3 months, respectively. The impact of the intervention was measured by preintervention and postintervention surveys for surgical patients with clean and clean-contaminated wounds. Information was collected on demographic characteristics and antibiotic use. The intervention focused mainly on educating surgical staff on the optimal timing and duration of antibiotics used for surgical prophylaxis. Only 3 hospitals identified a surgeon to audit antibiotic surgical prescriptions. The primary outcome measures were the percentages of surgical patients receiving optimal timing and duration of surgical prophylaxis.

RESULTS

Data were collected for 745 patients before the intervention and for 558 patients after the intervention. The optimal timing of the first dose improved significantly in 3 hospitals, increasing from 6.7% to 38.7% (P < .01), from 2.6% to 15.2% (P < .01), and from 0% to 11% (P < .01). All hospitals showed a significant rise in the optimal duration of surgical prophylaxis, with an overall increase of 3%-28% (P < .01). Days of therapy per 1000 patient-days were decreased significantly in hospitals A, B, C, and D, with no change in hospital E.

CONCLUSIONS

An AMS program focusing on education supported by auditing and feedback can have a significant impact on optimizing antibiotic use in surgical prophylaxis practices.

Determinants of hand hygiene compliance in Egypt: building blocks for a communication strategy

Hand hygiene of health-care staff is one of the most important interventions in reducing transmission of nosocomial infections. This qualitative study aimed to understand the behavioural determinants of hand hygiene in order to develop sustainable interventions to promote hand hygiene in hospitals. Fourteen focus group discussions were conducted with nurses in 2 university hospitals in Egypt. The interviews were tape recorded and transcribed. Thematic analysis was conducted by 2 independent investigators. The findings highlighted that nurses did not perceive the benefits of hand hygiene, and that they linked the need to wash hands to a sense of dirtiness. Knowledge of hand hygiene and related products was limited and preference for water and soap was obvious. Environmental constraints, lack of role models and social control were identified as barriers for compliance with hand hygiene. A multi-faceted hand hygiene strategy was developed based on existing cultural concepts valued by the hospital staff.

Patient Attitudes and Beliefs and Provider Practices Regarding Antibiotic Use for Acute Respiratory Tract Infections in Minya, Egypt

The inappropriate use of antibiotics in the community is one of the major causes of antimicrobial resistance. This study aimed to explore the physician prescribing pattern of antibiotics for acute respiratory infections (ARIs) and to explore the knowledge, attitudes, and practices of patients regarding antibiotic use for ARIs. The study was conducted in Upper Egypt and used quantitative and qualitative research techniques. Eligible patients exiting outpatient clinics with ARIs were invited to participate in the study. A qualitative study was conducted through 20 focus group discussions. Out of 350 encounters for patients with various ARIs, 292 (83%) had been prescribed at least one antibiotic. Factors significantly associated with antibiotic prescribing for adults included patient preference that an antibiotic be prescribed. For children younger than 18, presentation with fever, cough, loss of appetite, and sore throat, along with the caregiver’s antibiotic preference, were associated with an antibiotic prescription. Several misconceptions regarding antibiotic use among community members were stated, such as the strong belief of the curing and prophylactic power of antibiotics for the common cold. Interventions to promote proper antibiotic use for ARIs need to be piloted, targeting both physicians and the public. Educational programs for physicians and campaigns to raise public awareness regarding proper antibiotic use for ARIs need to be developed.

A Point Prevalence Survey of Antibiotic Use in 18 Hospitals in Egypt

Inappropriate antibiotic use leads to increased risk of antibiotic resistance and other adverse outcomes. The objectives of the study were to determine the prevalence and characteristics of antibiotic use in Egyptian hospitals to identify opportunities for quality improvement. A point prevalence survey was conducted in 18 hospitals in March 2011. A total of 3408 patients were included and 59% received at least one antibiotic, with the most significant use among persons <12 years and intensive care unit patients (p < 0.05). Third generation cephalosporin were the most commonly prescribed antibiotics (28.7% of prescriptions). Reasons for antibiotic use included treatment of community-(27%) and healthcare-associated infections (11%) and surgical (39%) and medical (23%) prophylaxis. Among surgical prophylaxis recipients, only 28% of evaluable cases received the first dose within two hours before incision and only 25% of cases received surgical prophylaxis for <24 h. The prevalence of antibiotic use in Egyptian hospitals was high with obvious targets for antimicrobial stewardship activities including provision of antibiotic prescription guidelines and optimization of surgical and medical prophylaxis practices.

Understanding Antibiotic Use in Minya District, Egypt: Physician and Pharmacist Prescribing and the Factors Influencing Their Practices

Overuse of antibiotics has contributed to the emergence of antibiotic-resistant bacteria globally. In Egypt, patients can purchase antibiotics without a prescription, and we hypothesized frequent inappropriate antibiotic prescribing and dispensing. We interviewed physicians (n = 236) and pharmacists (n = 483) and conducted focus groups in Minya, Egypt, to assess attitudes and practices regarding antibiotic prescribing for outpatient acute respiratory infections (ARI). Antibiotics were reportedly prescribed most of the time or sometimes for colds by 150 (64%) physicians and 326 (81%) pharmacists. The most commonly prescribed antibiotics were β-lactams. Macrolides were the second most commonly prescribed for colds and sinusitis. The prescription of more than one antibiotic to treat pneumonia was reported by 85% of physicians. Most respondents thought antibiotic overuse contributes to resistance and reported “patient self-medication” as the biggest driver of overuse. Fifty physicians (21%) reported that they had prescribed antibiotics unnecessarily, citing patient over-the-counter access as the reason. Physicians <40 years of age and those who treat adults were more likely to prescribe antibiotics for colds. Overall, we found a high rate of unwarranted outpatient antibiotic prescribing and dispensing for ARIs. Patient access to OTC antibiotics contributes to over-prescribing. National guidelines for ARI treatment, provider education and national policy requiring a physician’s prescription for antibiotics may improve appropriate antibiotic use in Egypt.

Incidence and pathogen distribution of healthcare-associated infections in pilot hospitals in Egypt

OBJECTIVE

To report type and rates of healthcare-associated infections (HAIs) as well as pathogen distribution and antimicrobial resistance patterns from a pilot HAI surveillance system in Egypt.

METHODS

Prospective surveillance was conducted from April 2011 through March 2012 in 46 intensive care units (ICUs) in Egypt. Definitions were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. Trained healthcare workers identified HAIs and recorded data on clinical symptoms and up to 4 pathogens. A convenience sample of clinical isolates was tested for antimicrobial resistance at a central reference laboratory. Multidrug resistance was defined by international consensus criteria.

RESULTS

ICUs from 11 hospitals collected 90,515 patient-days of surveillance data. Of 472 HAIs identified, 47% were pneumonia, 22% were bloodstream infections, and 15% were urinary tract infections; case fatality among HAI case patients was 43%. The highest rate of device-associated infections was reported for ventilator-associated pneumonia (pooled mean rate, 7.47 cases per 1,000 ventilator-days). The most common pathogens reported were Acinetobacter species (21.8%) and Klebsiella species (18.4%). All Acinetobacter isolates tested (31/31) were multidrug resistant, and 71% (17/24) of Klebsiella pneumoniae isolates were extended-spectrum β-lactamase producers.

CONCLUSIONS

Infection control priorities in Egypt should include preventing pneumonia and preventing infections due to antimicrobial-resistant pathogens.

Learning about Barriers to Care for People Living with HIV in Egypt: A Qualitative Exploratory Study

The purpose of this study was to identify obstacles health care workers face in providing care for people living with HIV and AIDS (PLWHA). Based on these findings, health authorities can design interventions to support health care workers in providing better medical care for PLWHA. Thirty in-depth interviews were conducted with physicians and nurses in one 300-bed tertiary care public hospital in Giza, Egypt. Thematic analysis was conducted by 2 investigators. Five main themes were identified (1) fear of infection; (2) disbelief in effectiveness of infection control measures to protect against HIV; (3) misconceptions regarding medical care for PLWHA; (4) fear of secondary stigma; and (5) moral judgments toward PLWHA and negative connotations related to HIV. Interventions targeting health care workers should be multidimensional, including knowledge and skills building as well as value and attitude change. Reducing stigma among health care workers will improve access to care for PLWHA.

Influenza surveillance in 15 countries in Africa, 2006-2010

BACKGROUND

In response to the potential threat of an influenza pandemic, several international institutions and governments, in partnership with African countries, invested in the development of epidemiologic and laboratory influenza surveillance capacity in Africa and the African Network of Influenza Surveillance and Epidemiology (ANISE) was formed.

METHODS

We used a standardized form to collect information on influenza surveillance system characteristics, the number and percent of influenza-positive patients with influenza-like illness (ILI), or severe acute respiratory infection (SARI) and virologic data from countries participating in ANISE.

RESULTS

Between 2006 and 2010, the number of ILI and SARI sites in 15 African countries increased from 21 to 127 and from 2 to 98, respectively. Children 0-4 years accounted for 48% of all ILI and SARI cases of which 22% and 10%, respectively, were positive for influenza. Influenza peaks were generally discernible in North and South Africa. Substantial cocirculation of influenza A and B occurred most years.

CONCLUSIONS

Influenza is a major cause of respiratory illness in Africa, especially in children. Further strengthening influenza surveillance, along with conducting special studies on influenza burden, cost of illness, and role of other respiratory pathogens will help detect novel influenza viruses and inform and develop targeted influenza prevention policy decisions in the region.

Case control study to identify risk factors for acute hepatitis C virus infection in Egypt

BACKGROUND

Identification of risk factors of acute hepatitis C virus (HCV) infection in Egypt is crucial to develop appropriate prevention strategies.

METHODS

We conducted a case-control study, June 2007-September 2008, to investigate risk factors for acute HCV infection in Egypt among 86 patients and 287 age and gender matched controls identified in two infectious disease hospitals in Cairo and Alexandria. Case-patients were defined as: any patient with symptoms of acute hepatitis; lab tested positive for HCV antibodies and negative for HBsAg, HBc IgM, HAV IgM; and 7-fold increase in the upper limit of transaminase levels. Controls were selected from patients' visitors with negative viral hepatitis markers. Subjects were interviewed about previous exposures within six months, including community-acquired and health-care associated practices.

RESULTS

Case-patients were more likely than controls to have received injection with a reused syringe (OR=23.1, CI 4.7-153), to have been in prison (OR=21.5, CI 2.5-479.6), to have received IV fluids in a hospital (OR=13.8, CI 5.3-37.2), to have been an IV drug user (OR=12.1, CI 4.6-33.1), to have had minimal surgical procedures (OR=9.7, CI 4.2-22.4), to have received IV fluid as an outpatient (OR=8, CI 4-16.2), or to have been admitted to hospital (OR=7.9, CI 4.2-15) within the last 6 months. Multivariate analysis indicated that unsafe health facility practices are the main risk factors associated with transmission of HCV infection in Egypt.

CONCLUSION

In Egypt, focusing acute HCV prevention measures on health-care settings would have a beneficial impact.

Poultry rearing and slaughtering practices in rural Egypt: an exploration of risk factors for H5N1 virus human transmission

Please cite this paper as: Lohiniva et al. (2012) Poultry rearing and slaughtering practices in rural Egypt: an exploration of risk factors for H5N1 virus human transmission. Influenza and Other Respiratory Viruses DOI: 10.1111/irv.12023.

Background  Highly pathogenic avian influenza (H5N1) virus continues to cause infections in Egypt. This study describes the practices associated with raising and slaughtering household poultry to identify risk factors for H5N1 infection and reasons for non‐compliance with preventive measures.

Methods  An investigation was conducted of 56 households with household flocks (19 households with human H5N1 cases, 19 with poultry H5N1 cases, and 18 with no reported poultry or human H5N1 cases). Data were collected via structured observations and in‐depth interviews.

Results  Half of the households kept at least some free‐range poultry and mixed at least some different species of poultry as it was considered beneficial for the poultry. Feeding and cleaning practices exposed children to contact with poultry; slaughtering contaminated homes; use of personal protective barriers was not a norm; waste management exposed the communities to slaughtering waste and dead chickens; and reporting of sick and dead poultry was not a practice. Only minor changes in poultry‐handling took place following H5N1 virus outbreaks.

Discussion  H5N1 virus prevention in Egypt represents both an epidemiological and socio‐cultural challenge. Traditional poultry‐rearing practices that likely increase exposures to H5N1‐infected poultry are common throughout Egypt. Despite education campaigns following sporadic H5N1 outbreaks, no differences in these practices could be detected between households with previous H5N1 human or poultry cases and those households with any previous experience with H5N1. Development of H5N1 infection–related education campaign strategies should focus on perceptions underlying traditional practices in order to tailor public awareness messages that are meaningful for communities.

Device-associated nosocomial infection rates in intensive care units at Cairo University hospitals: first step toward initiating surveillance programs in a resource-limited country

BACKGROUND

Device associated infections (DAIs) have major impact on patient morbidity and mortality.

METHODS

This study involved active prospective surveillance to measure the incidence of DAIs, evaluate microbiological profiles, and investigate excessive mortality in intensive care units (ICUs) in 3 hospitals of Cairo University applying the US Centers for Disease Control and Prevention's National Healthcare Safety Network case definitions for ventilator-associated pneumonia (VAP), catheter-associated urinary tract infection (CAUTI), and central-line associated bloodstream infection (CLABSI). Data were collected between March 2009 and May 2010.

RESULTS

A total of 1,101 patients were hospitalized for a total of 10,869 days, had 4,734 device-days, and acquired 97 DAIs, with an overall rate of 20.5/1,000 ICU days. VAP was the most commonly identified infection (88.7%); followed by CLABSI (8.2%) and CAUTI (3.1%). Excess mortality was 48% (relative risk, 1.9; P < .001) for CAUTI, 12.9% (relative risk, 1.2; 95% confidence interval, 1.1-1.4; P < .05) for VAP, and 45.7% for CLABSI. Acinetobacter baumannii was the most frequently isolated pathogen (36.1%), followed by Klebsiella pneumoniae (29.2%) and Pseudomonas aeruginosa (22.2%). High antimicrobial resistance was identified, with 85% of A baumannii isolates resistant to ciprofloxacin and imipenem, 76% of K pneumoniae isolates were extended-spectrum β-lactamase producers, and 56.3% P aeruginosa isolates resistant to imipenem (56.3%).

CONCLUSION

High rates of DAI and antimicrobial resistance require strengthening infection control, instituting surveillance systems, and implementing evidence-based preventive strategies.

Acute respiratory illness and health-seeking behavior in Egyptian villages: enhancing pandemic preparedness by understanding local realities

The emergence of influenza viruses has raised awareness worldwide about influenza pandemic risks. Pandemic preparedness emphasizes development of risk communication and surveillance systems. The objective was to explore community classification of Acute Respiratory Illness (ARI) and health-seeking behaviors. Twenty in-depth interviews and 18 focus group discussions were conducted with caretakers in Egypt. The interviews were recorded, transcribed, and analyzed using the thematic analysis. ARI terminology contained few terms, usage of them was complex, and microorganism not part of illness explanation. Severe ARI was associated with social stigma. Homecare included extensive use of medications. In mild and severe ARI, health-seeking determinants varied. Classification of ARI parallels World Health Organization case definitions for ARI, facilitating risk communication. Homecare practices are social norms that can be expanded to include messages on ARI. Risk communication strategies and surveillance systems need to consider socio-cultural understanding of ARI.

Incidence and modifiable risk factors of surveillance of surgical site infections in Egypt: a prospective study

BACKGROUND

Surgical site infections (SSIs) contribute significantly to patient morbidity and mortality and exhaust health care system resources. The main objectives of the study were to describe the incidence rates of SSIs among patients undergoing urologic or cardiothoracic surgeries, the associated risk factors, and the common causative etiologies found at Alexandria University Hospital in Egypt.

METHODS

A prospective active surveillance study for patients undergoing urologic and cardiothoracic surgeries was implemented from July 2009 to December 2010. Patients were inspected daily for developing SSIs and with a 30-day postoperative follow-up. Wound swabs were obtained from patients who had clinical signs suggestive of infection. Swabs were cultured for bacterial identification and tested for antimicrobial sensitivity. Standard Centers for Disease Control and Prevention National Health Safety Network case definitions were used.

RESULTS

SSIs occurred in 187 (17%) of patients with complete follow-up (n = 1,062), of which 106 (57%) occurred in-hospital and 81 (43%) occurred after discharge. Higher SSI rates were observed in cardiothoracic surgeries (23.3%), compared with urologic surgeries (9%) (P < .001). A stepwise logistic model identified an increased risk of SSI for those who underwent cardiothoracic surgeries (odds ratio [OR], 4.7; 95% confidence interval [CI], 2.2-11.1), those aged >45 years (OR, 2.32; 95% CI, 1.35-4.01), increased duration of hospital stay before (OR, 1.03; 95% CI, 1.01-1.05) and after (OR, 1.07; 95% CI, 1.04-1.09) surgery, antibiotics ≤24 hours before surgery (OR, 2.54; 95% CI, 1.63-3.94), and dirty wounds (OR, 4.09; 95% CI, 1.60-10.43).

CONCLUSIONS

Measures to reduce the high rates of SSI need to be instituted through a multidisciplinary effort including infection control education and specific SSI prevention activities at Alexandria University Hospital.

Effects of hand hygiene campaigns on incidence of laboratory-confirmed influenza and absenteeism in schoolchildren, Cairo, Egypt

To evaluate the effectiveness of an intensive hand hygiene campaign on reducing absenteeism caused by influenza-like illness (ILI), diarrhea, conjunctivitis, and laboratory-confirmed influenza, we conducted a randomized control trial in 60 elementary schools in Cairo, Egypt. Children in the intervention schools were required to wash hands twice each day, and health messages were provided through entertainment activities. Data were collected on student absenteeism and reasons for illness. School nurses collected nasal swabs from students with ILI, which were tested by using a qualitative diagnostic test for influenza A and B. Compared with results for the control group, in the intervention group, overall absences caused by ILI, diarrhea, conjunctivitis, and laboratory-confirmed influenza were reduced by 40%, 30%, 67%, and 50%, respectively (p<0.0001 for each illness). An intensive hand hygiene campaign was effective in reducing absenteeism caused by these illnesses.

Antimicrobial resistance surveillance in the AFHSC-GEIS network

International infectious disease surveillance has been conducted by the United States (U.S.) Department of Defense (DoD) for many years and has been consolidated within the Armed Forces Health Surveillance Center, Division of Global Emerging Infections Surveillance and Response System (AFHSC-GEIS) since 1998. This includes activities that monitor the presence of antimicrobial resistance among pathogens. AFHSC-GEIS partners work within DoD military treatment facilities and collaborate with host-nation civilian and military clinics, hospitals and university systems. The goals of these activities are to foster military force health protection and medical diplomacy. Surveillance activities include both community-acquired and health care-associated infections and have promoted the development of surveillance networks, centers of excellence and referral laboratories. Information technology applications have been utilized increasingly to aid in DoD-wide global surveillance for diseases significant to force health protection and global public health. This section documents the accomplishments and activities of the network through AFHSC-GEIS partners in 2009.

Training initiatives within the AFHSC-Global Emerging Infections Surveillance and Response System: support for IHR (2005)

Training is a key component of building capacity for public health surveillance and response, but has often been difficult to quantify. During fiscal 2009, the Armed Forces Health Surveillance Center, Division of Global Emerging Infections Surveillance and Response System (AFHSC-GEIS) supported 18 partner organizations in conducting 123 training initiatives in 40 countries for 3,130 U.S. military, civilian and host-country personnel. The training assisted with supporting compliance with International Health Regulations, IHR (2005). Training activities in pandemic preparedness, outbreak investigation and response, emerging infectious disease (EID) surveillance and pathogen diagnostic techniques were expanded significantly. By engaging local health and other government officials and civilian institutions, the U.S. military’s role as a key stakeholder in global public health has been strengthened and has contributed to EID-related surveillance, research and capacity-building initiatives specified elsewhere in this issue. Public health and emerging infections surveillance training accomplished by AFHSC-GEIS and its Department of Defense (DoD) partners during fiscal 2009 will be tabulated and described.

Case-control study to evaluate risk factors for acute hepatitis B virus infection in Egypt

Hepatitis B virus (HBV) infection is a significant health problem in Egypt. To better define risk factors associated with HBV transmission, we conducted a case-control study among patients admitted with acute hepatitis to an infectious disease hospital in Cairo. A total of 60 cases and 120 controls were interviewed about various exposures within 6 months prior to admission. Univariate analysis revealed HBV case-patients were more likely to report providing injections to relatives or friends, injecting drug use, exposure to a household contact with hepatitis, exposure to invasive medical procedures and being in the military. Efforts should be made to implement strict infection control standards in Egypt.

Surveillance of catheter-associated urinary tract infection in 4 intensive care units at Alexandria university hospitals in Egypt

BACKGROUND

We sought to measure the incidence rate of catheter-associated urinary tract infections (CAUTIs), identify risk factors associated with acquiring the infections; and identify the etiologic and antibiotic resistant patterns associated with CAUTIs in the intensive care units (ICUs) of a large University Hospital in Alexandria, Egypt.

METHODS

Prospective active surveillance of CAUTIs was conducted in 4 ICUs during a 13-month period from January 1, 2007 through January 31, 2008 in Alexandria University Hospital using the standard Centers for Disease Control National Nosocomial Infection Surveillance (NNIS) case definitions. Rates were expressed as the number of infections per 1000 catheter days.

RESULTS

During the study period, 757 patients were monitored after ICU admission, with either existing indwelling urinary catheters (239), or got catheters inserted after ICU admission (518), for a total duration of 16301 patient days, and 10260 patient catheter days. A total of 161 episodes of infection were diagnosed, for an overall rate of 15.7 CAUTIs per 1000 catheter days. Important risk factors associated with acquiring CAUTI were female gender (Relative risk (RR), 1.7; 95% confidence interval (CI); 1.7-4.3), and previous catheterization within the same hospital admission (RR, 1.6; 95% CI; 1.3-1.96). Patients admitted to the chest unit, patients =40 years, patients with prolonged duration of catheterization, prolonged hospital and ICU stay had a significantly higher risk of acquiring CAUTIs. Out of 195 patients who had their urine cultured, 188 pathogens were identified for 161 infected patients; 96 (51%) were Candida, 63 (33.5%) gram negatives, 29 (15.4%) gram positives. The prevalence of ESBL producers among K. pneumoniae and E. coli isolates was 56% (14/25) and 78.6% (11/14), respectively.

CONCLUSION

Despite infection control policies and procedures, CAUTI rates remain a significant problem in Alexandria University hospital. Using the identified risk factors, tailored intervention strategies are now being implemented to reduce the rates of CAUTIs in these 4 ICUs.

Sentinel surveillance for patients with acute hepatitis in Egypt, 2001-04

Viral hepatitis is a major problem in Egypt. To define the epidemiology of the disease, sentinel surveillance was established in 5 hospitals in diverse areas of the country in 2001. Data were completed for patients meeting the case definition for viral hepatitis. Of a total of 5909 patients evaluated, 4189 (70.9%) showed positive antibody markers for hepatitis. Out of those, 40.2% had evidence of hepatitis A virus (HAV) infection, 30.0% hepatitis B virus (HBV) and 29.8% hepatitis C virus (HCV) infection. This surveillance system was useful in identifying the variable endemicity of acute HAV infection in different regions and for better understanding the epidemiology of HBV and HCV infection.

Injection prescribing patterns in public health care facilities in Egypt

This study assessed the frequency of and rationale for use of injections at health care facilities in Egypt based on WHO core drug use indicators. We reviewed 1406 prescriptions in 43 randomly selected hospitals and primary health care clinics in 2 governorates in Upper and Lower Egypt in 2001. Patients received an injection at 18.1% of encounters. The most frequently prescribed parenteral drugs were anti-infectives (56.9% of injections) and analgesics (13.7%). Injections were more often prescribed in hospitals than in primary health care clinics and in rural than in urban settings. Most injections (94.7%) could have been replaced by a suitable oral preparation. Further efforts are needed to enforce the essential medicines programme in Egypt to improve rational drug prescribing.

Helicobacter pylori infection and chronic, persistent cough: is there an association?

INTRODUCTION

Chronic, persistent cough is a common clinical problem, the cause of which sometimes remains unidentifiable.

AIMS

To study a potential association between Helicobacter pylori infection and chronic, persistent cough.

MATERIALS AND METHODS

A clinical observational study with symptom analysis, including 162 patients whose main presenting complaint was chronic, persistent cough of unidentifiable cause (study group) and 42 patients with chronic, non-specific laryngopharyngeal manifestations not including chronic cough (control group).

RESULTS

Active H pylori infection was present in 86.4 per cent (140/162) of patients in the chronic cough group, as opposed to 45.2 per cent (19/42) of the control group, as confirmed by detection of H pylori antigen in stool specimens. This difference was statistically significant (p<0.001). There was a significant improvement of the chronic cough of 75.4 per cent (98/130) of patients after successful H pylori eradication using appropriate medical therapy (p<0.001).

CONCLUSIONS

Helicobacter pylori infection may lead to laryngopharyngeal irritation, with several clinical manifestations including chronic, persistent cough. However, the exact mechanism of this requires further research.
