RESUMO
Women and underrepresented-in-medicine applicants value a climate for diversity when selecting graduate medical education training programs. Climate may not be accurately represented during virtual recruitment. Optimizing program websites may help overcome this barrier. We reviewed websites for adult infectious disease fellowships that participated in the 2022 National Resident Matching Program for emphasis on diversity, equity, and inclusion (DEI). Fewer than half expressed DEI language in their mission statement or had a dedicated DEI statement or webpage. Programs should consider emphasizing their commitment to DEI prominently on their websites, which may help recruit candidates from diverse backgrounds.

BACKGROUND: Foodborne botulism, a toxin-mediated illness caused by Clostridium botulinum, is a public health emergency. Types A, B, and E C. botulinum toxins commonly cause human disease. Outbreaks are often associated with homemade and fermented foods. Botulism is rarely reported in Africa and has never been reported in Ethiopia. CASE PRESENTATION: In March 2015, a cluster of family members from the Wollega, Oromia region, western Ethiopia presented with a symptom constellation suggestive of probable botulism. Clinical examination, epidemiologic investigation, and subsequent laboratory work identified the cause of the outbreak to be accidental ingestion of botulinum toxin in a traditional chili condiment called "Kochi-kocha," cheese, and clarified butter. Ten out of the fourteen family members who consumed the contaminated products had botulism (attack rate 71.4%) and five died (case fatality rate of 50%). Three of the patients were hospitalized, they presented with altered mental status (n = 2), profound neck and truncal weakness (n = 3), and intact extremity strength despite hyporeflexia (n = 3). The remnant food sample showed botulinum toxin type A with mouse bioassay and C. botulinum type A with culture. Blood drawn on day three of illness from 2/3 (66%) cases was positive for botulinum toxin type-A. Additionally, one of these two cases also had C. botulinum type A cultured from a stool specimen. Two of the cases received Botulism antitoxin (BAT). CONCLUSION: These are the first confirmed cases of botulism in Ethiopia. The disease occurred due to the consumption of commonly consumed homemade foods. Definite diagnoses of botulism cases are challenging, and detailed epidemiologic and laboratory investigations were critical to the identification of this case series. Improved awareness of botulism risk and improved food preparation and storage may prevent future illnesses. The mortality rate of botulism in resource-limited settings remains high. Countries should make a concerted effort to stockpile antitoxin as that is the easiest and quickest intervention after outbreak detection.

The increasing diversity in the US population is reflected in the patients who healthcare professionals treat. Unfortunately, this diversity is not always represented by the demographic characteristics of healthcare professionals themselves. Patients from underrepresented groups in the United States can experience the effects of unintentional cognitive (unconscious) biases that derive from cultural stereotypes in ways that perpetuate health inequities. Unconscious bias can also affect healthcare professionals in many ways, including patient-clinician interactions, hiring and promotion, and their own interprofessional interactions. The strategies described in this article can help us recognize and mitigate unconscious bias and can help create an equitable environment in healthcare, including the field of infectious diseases.

OBJECTIVE: Antimicrobial stewardship programs have been shown to help reduce the use of unnecessary antimicrobial agents in the hospital setting. To date, there has been very little data focusing on high-use areas, such as the medical ICU. A prospective intervention was done to assess guideline compliance, antimicrobial expenditure, and healthcare cost when an infectious disease fellow interacts regularly with the medical ICU team. DESIGN: A 3-month retrospective chart review was followed by a 3-month prospective intervention the following year. Two hundred forty-six total charts were reviewed to assess generally accepted guideline compliance, demographics, and microbiologic results. SETTING: Twenty-four-bed medical ICU at an 861-bed tertiary care, university teaching hospital in North Carolina. SUBJECTS: Patients receiving antibiotics in the medical ICU. INTERVENTION: During the intervention period, the infectious disease fellow reviewed the charts, including physician notes and microbiology data, and discussed antimicrobial use with the medical ICU team. MEASUREMENTS AND MAIN RESULTS: Antimicrobial use, treatment duration, Acute Physiology and Chronic Health Evaluation II scores, length of stay, mechanical ventilation days, and mortality rates were compared during the two periods. RESULTS: No baseline statistically significant differences in the two groups were noted (i.e., age, gender, race, or Acute Physiology and Chronic Healthcare Evaluation II scores). Indications for antibiotics included healthcare-associated (53%) and community-acquired pneumonias (17%). Significant reductions were seen in extended-spectrum penicillins (p=0.0080), carbapenems (p=0.0013), vancomycin (p=0.0040), and metronidazole (p=0.0004) following the intervention. Antimicrobial modification led to an increase in narrow-spectrum penicillins (p=0.0322). The intervention group had a significantly lower rate of treatments that did not correspond to guidelines (p<0.0001). There was a reduction in mechanical ventilation days (p=0.0053), length of stay (p=0.0188), and hospital mortality (p=0.0367). The annual calculated healthcare savings was $89,944 in early antibiotic cessation alone. CONCLUSION: Active communication with an infectious disease practitioner can significantly reduce medical ICU antibiotic overuse by earlier modification or cessation of antibiotics without increasing mortality. This in turn can reduce healthcare costs, foster prodigious education, and strengthen relations between the subspecialties.

OBJECTIVES: To assess the time lag between the diagnosis of human immunodeficiency virus (HIV) and the initiation of antiretroviral therapy (ART) in pregnant women. METHODS: A retrospective chart review of 105 deliveries from HIV-positive women from January 2001 to June 2009 was undertaken. RESULTS: One hundred five HIV-infected pregnant women were identified and studied. Forty-eight women were diagnosed during the prenatal visit: 21 in the first trimester, 17 in the second trimester, and 10 in the third trimester. Forty-five had undetectable viral loads at delivery. The time lag between diagnosis of HIV and initiation of ART was 1 month for 31% and 3 months for 28.5%. CONCLUSIONS: The time lag between diagnosis of HIV and initiation of ART was more than 1 month in 69% of the expectant mothers, which may have contributed to the failure in viral suppression. Implementation of HIV screening and a more effective means of communication between prenatal and HIV clinics are required to help reduce vertical transmission of the virus to neonates.

The fungus Paecilomyces lilacinus is a rare but emerging pathogen that causes severe human infections, especially in immunocompromised hosts. It is an important organism to identify due to its poor susceptibility to conventional antifungal drugs, including amphotericin B, itraconazole, and fluconazole. Oculomycosis and cutaneous infections are the two most common manifestations of P. lilacinus infections. Voriconazole has been used successfully to treat P. lilacinus endophthalmitis, but reports of skin and soft tissue infections treated with voriconazole are limited to six prior publications. Our immunocompromised patient had a subcutaneous P. lilacinus infection successfully treated with 3 months of voriconazole therapy.

OBJECTIVES: The rate of treatment of hepatitis C virus (HCV) infection in human immunodeficiency virus-hepatitis C virus (HIV-HCV) co-infected patients remains historically low. We undertook a retrospective study to review our treatment rate and factors that have negatively influenced this rate. In those treated, we reviewed outcomes and compared results with prior studies. METHODS: A total of 233 patients infected with HIV and HCV were followed for 7 years in the infectious diseases (ID) clinic of East Carolina University. Proper follow-up evaluation was determined based on the presence of HCV polymerase chain reaction viral load and genotype testing. The number of patients treated, response to treatment, and reason for no treatment were determined by chart review. RESULTS: Of 233 patients with positive HCV serology, 48 were excluded due to undetectable HCV viral load. Of the remaining 185 patients, 142 (77%) were evaluated by testing for HCV viral load and genotype, but only 112 of those who were followed up in the clinic regularly were considered eligible for therapy. Fourteen of 112 (12.5%) of patients underwent treatment and only 1 in 14 (7%) attained sustained virological response (SVR). Of the patients tested, 96% had HCV genotype 1, and 81% were African American. CONCLUSIONS: The majority of our HIV-HCV co-infected patients received a proper HCV evaluation, but only 12.5% were offered therapy. Of those treated, only one patient achieved SVR. The higher proportion of genotype 1 and African American patient population are considered the main reasons for the low SVR. Low SVR rate, high rate of adverse effects, and the unique demography of our patient population have been the main reasons for the lower treatment rate.

BACKGROUND: COVID-19 is a deadly pandemic caused by an RNA virus that belongs to the family of CORONA virus. To counter the COVID-19 pandemic in resource limited settings, it is essential to identify the risk factors of COVID-19 mortality. This study was conducted to identify the social and clinical determinants of mortality in COVID-19 patients hospitalized in four treatment centers of Tigray, Northern Ethiopia. METHODS: We reviewed data from 6,637 COVID-19 positive cases that were reported from May 7, 2020 to October 28, 2020. Among these, 925 were admitted to the treatment centers because of their severity and retrospectively analyzed. The data were entered into STATA 16 version for analysis. The descriptive analysis such as median, interquartile range, frequency distribution and percentage were used. Binary logistic regression model was fitted to identify the potential risk factors of mortality of COVID-19 patients. The adjusted odds ratio (AOR) with 95% confidence interval was used to determine the magnitude of the association between the outcome and predictor variables. RESULTS: The median age of the patients was 30 years (IQR, 25-44) and about 70% were male patients. The patients in the non-survivor group were much older than those in the survivor group (median 57.5 years versus 30 years, p-value < 0.001). The overall case fatality rate was 6.1% (95% CI: 4.5% - 7.6%) and was increased to 40.3% (95% CI: 32.2% - 48.4%) among patients with critical and severe illness. The proportions of severe and critical illness in the non-survivor group were significantly higher than those in the survivor group (19.6% versus 5.1% for severe illness and 80.4% versus 4.5% for critical illness, all p-value < 0.001). One or more pre-existing comorbidities were present in 12.5% of the patients: cardiovascular diseases (42.2%), diabetes mellitus (25.0%) and respiratory diseases (16.4%) being the most common comorbidities. The comorbidity rate in the non-survivor group (44.6%) was higher than in the survivor group (10.5%). The results from the multivariable binary regression showed that the odds of mortality was higher for patients who had cardiovascular diseases (AOR = 2.49, 95% CI: 1.03-6.03), shortness of breath (AOR = 9.71, 95% CI: 4.73-19.93) and body weakness (AOR = 3.04, 95% CI: 1.50-6.18). Moreover, the estimated odds of mortality significantly increased with patient's age. CONCLUSIONS: Age, cardiovascular diseases, shortness of breath and body weakness were the predictors for mortality of COVID-19 patients. Knowledge of these could lead to better identification of high risk COVID-19 patients and thus allow prioritization to prevent mortality.

Objective: Surgical site infections (SSIs) greatly burden healthcare systems around the world, particularly in low- and middle-income countries. We sought to employ the Systems Engineering Initiative for Patient Safety (SEIPS) model to better characterize SSI prevention practices and factors affecting adherence to prevention guidelines at Jimma University Medical Center (JUMC). Design: Our cross-sectional study consisted of semistructured interviews designed to elicit perceptions of and barriers and facilitators to SSI prevention among surgical staff and observations of current preoperative, perioperative, and postoperative SSI prevention practices in surgical cases. Interviews were recorded, manually transcribed, and thematically coded within the SEIPS framework. Trained observers recorded compliance with the World Health Organization's SSI prevention recommendations. Setting: A tertiary-care hospital in Jimma, Ethiopia. Participants: Surgical nurses, surgeons, and anesthetists at JUMC. Results: Within 16 individual and group interviews, participants cited multiple barriers to SSI prevention including shortages of water and antiseptic materials, lack of clear SSI guidelines and training, minimal Infection Prevention Control (IPC) interaction with surgical staff, and poor SSI tracking. Observations from nineteen surgical cases revealed high compliance with antibiotic prophylaxis (94.7%), hand scrubbing (100%), sterile gloves and instrument use (100%), incision site sterilization (100%), and use of surgical safety checklist (94.7%) but lower compliance with preoperative bathing (26.3%), MRSA screening (0%), and pre- and postoperative glucose (0%, 10.5%) and temperature (57.9%, 47.3%) monitoring. Conclusions: Utilizing the SEIPS model helped identify institution-specific barriers and facilitators that can inform targeted interventions to increase compliance with currently underperformed SSI prevention practices at JUMC.
RESUMO
We aimed to apply the Systems Engineering Initiative for Patient Safety (SEIPS) model to increase effectiveness and sustainability of the World Health Organization's (WHOs) hand hygiene (HH) guidelines within healthcare systems. Our cross-sectional, mixed-methods study took place at Jimma University Medical Center (JUMC), a tertiary care hospital in Jimma, Ethiopia, between November 2018 and August 2020 and consisted of three phases: baseline assessment, intervention, and follow-up assessment. We conducted questionnaires addressing HH knowledge and attitudes, interviews to identify HH barriers and facilitators within the SEIPS framework, and observations at the WHO's 5 moments of HH amongst healthcare workers (HCWs) at JUMC. We then implemented HH interventions based on WHO guidelines and results from our baseline assessment. Follow-up HH observations were conducted months later during the Covid-19 pandemic. 250 HCWs completed questionnaires with an average knowledge score of 61.4% and attitude scores indicating agreement that HH promotes patient safety. Interview participants cited multiple barriers to HH including shortages and location of HH materials, inadequate training, minimal Infection Prevention Control team presence, and high workload. We found an overall baseline HH compliance rate of 9.4% and a follow-up compliance rate of 72.1%. Drastically higher follow-up compared to baseline compliance rates were likely impacted by our HH interventions and Covid-19. HCWs showed motivation for patient safety despite low HH knowledge. Utilizing the SEIPS model helped identify institution-specific barriers that informed targeted interventions beyond WHO guidelines aimed at increasing effectiveness and sustainability of HH efforts.

BACKGROUND: Antimicrobial resistance is one of the major public health challenges in Ethiopia. However, there is no comprehensive summary of existing AMR data in the country. AIM: To determine the prevalence of antimicrobial resistance and its clinical implications in Ethiopia. METHODS: A systematic literature search was performed on the PubMed/Medline database. Original studies on antimicrobial resistance conducted in Ethiopia between 1st January 2009 and 31st July 2019 were included. The outcome measure was the number of isolates resistant to antimicrobial agents in terms of specific pathogens, and disease condition. Data was calculated as total number of resistant isolates relative to the total number of isolates per specific pathogen and medication. RESULTS: A total of 48,021 study participants enrolled from 131 original studies were included resulting in 15,845 isolates tested for antimicrobial resistance. The most common clinical sample sources were urine (28%), ear, nose, and throat discharge collectively (27%), and blood (21%). All the studies were cross-sectional and 83% were conducted in hospital settings. Among Gram-positive bacteria, the reported level of resistance to vancomycin ranged from 8% (Enterococcus species) to 20% (S. aureus). E. coli, K. pneumoniae and P. aeruginosa were the most common Gram-negative pathogens resistant to key antimicrobial agents described in the national standard treatment guideline and were associated with diverse clinical conditions: urinary tract infections, diarrhea, surgical site infections, pneumonia, ocular infections, and middle ear infections. CONCLUSION: Overall, there is a high prevalence of antimicrobial resistance in Ethiopia. Empirical treatment of bacterial infections needs to be guided by up-to-date national guidelines considering local antimicrobial susceptibility patterns. Equipping diagnostic laboratories with culture and drug susceptibility testing facilities, and establishing a strong antimicrobial stewardship program should be high priorities.

The war in Tigray region of Ethiopia that started in November 2020 and is still ongoing has brought enormous damage to the health system. This analysis provides an assessment of the health system before and during the war. Evidence of damage was compiled from November 2020 to June 2021 from various reports by the interim government of Tigray, and also by international non-governmental organisations. Comparison was made with data from the prewar calendar year. Six months into the war, only 30% of hospitals, 17% of health centres, 11.5% of ambulances and none of the 712 health posts were functional. As of June 2021, the population in need of emergency food assistance in Tigray increased from less than one million to over 5.2 million. While the prewar performance of antenatal care, supervised delivery, postnatal care and children vaccination was 64%, 73%, 63% and 73%, respectively, but none of the services were likely to be delivered in the first 90 days of the war. A conservative estimate places the number of girls and women raped in the first 5 months of the war to be 10 000. These data indicate a widespread destruction of livelihoods and a collapse of the healthcare system. The use of hunger and rape as a weapon of war and the targeting of healthcare facilities are key components of the war. To avert worsening conditions, an immediate intervention is needed to deliver food and supplies and rehabilitate the healthcare delivery system and infrastructure.

BACKGROUND: There is very little data on long-term immune recovery responses in patients on suppressive antiretroviral therapy (ART) in the setting of sub-Saharan Africa (SSA). Thus, we sought to determine CD4+ T-cell, CD8+ T-cell and CD4/CD8 ratio responses in a cohort of HIV infected individuals on sustained suppressive ART followed up for more than a decade. METHODS: The cohort comprised adult patients who started ART between 2001 and 2007 and followed for up to 14 years. Trends in median CD4+ T-cells, CD8+ T-cells and CD4/CD8 ratio were reviewed retrospectively. Poisson regression models were used to identify factors associated with achieving normalized T-cell biomarkers. Kaplan-Meier curves were used to estimate the probability of attaining normalized counts while on suppressive ART. RESULTS: A total of 227 patients with a median duration of follow-up on ART of 12 (IQR: 10.5-13.0) years were included. CD4 cell count increased from baseline median of 138 cells (IQR: 70-202) to 555 cells (IQR: 417-830). CD4 cell increased continuously up until 5 years, after which it plateaued up until 14 years of follow up. Only 69.6% normalized their CD4 cell count within a median of 6.5 (IQR: 3.0-10.5) years. In addition, only 15.9% of the cohort were able to achieve the median reference CD4+ T-cell threshold count in Ethiopians (≈760 cells/µL). CD8+ T-cell counts increased initially until year 1, after which continuous decrease was ascertained. CD4/CD8 ratio trend revealed continuous increase throughout the course of ART, and increased from a median baseline of 0.14 (IQR: 0.09-0.22) to a median of 0.70 (IQR: 0.42-0.95). However, only 12.3% normalized their ratio (≥ 1.0) after a median of 11.5 years. In addition, only 8.8% of the cohort were able to achieve the median reference ratio of healthy Ethiopians. CONCLUSION: Determination of both CD4+ and CD8+ T-cells, along with CD4/CD8 ratio is highly relevant in long-term follow-up of patients to assess immune recovery. Monitoring ratio levels may serve as a better biomarker risk for disease progression among patients on long-term ART. In addition, the findings emphasize the relevance of initiation of ART at the early stage of HIV-1 infection.

INTRODUCTION: Since its emergence in late December 2019, COVID-19 has rapidly developed into a pandemic in mid of March with many countries suffering heavy human loss and declaring emergency conditions to contain its spread. The impact of the disease, while it has been relatively low in the sub-Saharan Africa (SSA) as of May 2020, is feared to be potentially devastating given the less developed and fragmented healthcare system in the continent. In addition, most emergency measures practised may not be effective due to their limited affordability as well as the communal way people in SSA live in relative isolation in clusters of large as well as smaller population centres. METHODS: To address the acute need for estimates of the potential impacts of the disease once it sweeps through the African region, we developed a process-based model with key parameters obtained from recent studies, taking local context into consideration. We further used the model to estimate the number of infections within a year of sustained local transmissions under scenarios that cover different population sizes, urban status, effectiveness and coverage of social distancing, contact tracing and usage of cloth face mask. RESULTS: We showed that when implemented early, 50% coverage of contact tracing and face mask, with 33% effective social distancing policies can bringing the epidemic to a manageable level for all population sizes and settings we assessed. Relaxing of social distancing in urban settings from 33% to 25% could be matched by introduction and maintenance of face mask use at 43%. CONCLUSIONS: In SSA countries with limited healthcare workforce, hospital resources and intensive care units, a robust system of social distancing, contact tracing and face mask use could yield in outcomes that prevent several millions of infections and thousands of deaths across the continent.

BACKGROUND: The role of CD4/CD8 ratio on the incidence of tuberculosis (TB) in patients on antiretroviral therapy (ART) is unknown. Thus, we sought to determine whether the CD4/CD8 ratio was associated with development of TB in a cohort of HIV infected individuals on ART followed up for more than a decade in the setting of sub-Saharan Africa (SSA). METHODS: The cohort comprised adult patients who started ART between 2001 and 2007 and followed for up to 15 years. Clinical data were collected in retrospective manner. Patients with an AIDS defining illness or a CD4 count <200 cell/µL were started with a combination of ART. The participants have clinic visits every 6 months and/or as needed. Poisson regression models were used to identify factors associated with development of incident TB. Kaplan-Meier curves were used to estimate the probability of incident TB while on ART. RESULTS: A total of 347 patients with a median duration of follow-up on ART of 11.5 (IQR: 10.0-12.5) years were included. Incident TB developed in 47 patients during the 3259 person-years of follow-up, the majority (76.6%) occurred within five year of ART initiation. On univariate analysis, poor ART adherence (RR:2.57, 95% CI: 1.28-5.17), time-updated CD4 cell count of lower than 200 (RR: 4.86, 95%CI 2.33-10.15), or CD4 cell count between 200 and 500 (RR: 4.68, 95% CI: 2.17-10.09), time-updated CD8 cell count lower than 500 (RR: 2.83 95% CI 1.31-6.10), or CD8 cell count over 1000 (RR: 2.23, 95% CI: 1.12-4.45), time-updated CD4/CD8 ratio of less than 0.30 (RR: 6.00, 95% CI: 2.96-12.14), lack of normalization of CD4 T-cell count (RR: 6.13, 95% CI: 2.20-17.07), and virological failure (RR: 2.35 (95% CI: 1.17-4.71) were all associated with increased risk of incident TB. In multivariate analysis, however, time-updated CD4/CD8 ratio of less than 0.30 (adjusted RR: 4.08, 95% CI: 1.31-12.68) was the only factor associated with increased risk of developing incident TB (p = 0.015). Similar results were obtained in a sensitivity analysis by including only those virally suppressed patients (n = 233, 69% of all patients). In this group, CD4/CD8 ratio of less than 0.30 was associated with development of incident TB (adjusted RR: 4.02, 95% CI: 1.14-14.19, p = 0.031). Overall, the incidence rate of TB in patients with an updated CD4/CD8 ratio of less than 0.30 was more than 5-fold higher when compared with those with a ratio more than 0.45. CONCLUSION: Low CD4/CD8 ratio is independently associated with an increased risk of incident TB despite viral suppression. CD4/CD8 ratio may serve as a biomarker for identifying patients at risk of TB in patients on ART in the setting of SSA.

BACKGROUND: There are scant data regarding hepatitis C (HCV) virologic response to directly acting antiviral agents (DAAs) in chronic hepatitis B (HBV) and HCV coinfected persons. HCV treatment response in those with spontaneously cleared HBV infection is unknown. METHODS: All HCV infected persons treated with a DAA regimen in ERCHIVES were identified and categorized into HBV/HCV-coinfected (HBsAg, HBV DNA or both positive), HCV-monoinfected, and resolved HBV (isolated HBcAb+). SVR rates were determined and compared for all groups. Logistic regression model was used to determine factors associated with SVR. RESULTS: Among 115 HCV/HBV-coinfected, 38,570 HCV-monoinfected persons, and 13,096 persons with resolved HBV, 31.6% of HCV/HBV-coinfected, 24.6% of HCV-monoinfected and 26.4% with resolved HBV had cirrhosis at baseline. SVR was achieved in 90.4% of HCV/HBV-coinfected, 83.4% of HCV-monoinfected and 84.5% of those with resolved HBV infection (P = 0.04 HCV/HBV vs. HCV monoinfected). In a logistic regression model, those with HCV/HBV were more likely to achieve SVR compared with HCV monoinfected (OR 2.25, 95% CI 1.17, 4.31). For HCV/HBV coinfected, the SVR rates dropped numerically with increasing severity of liver fibrosis (P-value non-significant). Factors associated with a lower likelihood of attaining SVR included cirrhosis at baseline (OR 0.85, 95% CI 0.80, 0.92), diabetes (OR 0.93, 95% CI 0.87, 0.99) and higher pre-treatment HCV RNA (OR 0.86, 95% CI 0.84, 0.87). CONCLUSION: HBV/HCV-coinfected persons have higher overall SVR rates with newer DAA regimens. Though not statistically significant, the virologic response is graded, with decreasing SVR rates with increasing degree of liver fibrosis as determined by the FIB-4 scores.

OBJECTIVES: To determine what barriers and facilitators to antibiotic stewardship exist within a healthcare facility. SETTING: 1300-bed tertiary care private hospital located in the state of Kerala, India. PARTICIPANTS: 31 semistructured interviews and 4 focus groups with hospital staff ranging from physicians, nurses, pharmacists and a clinical microbiologist. RESULTS: Key facilitators of antibiotic stewardship (AS) at the hospital included a dedicated committee overseeing appropriate inpatient antibiotic use, a prompt microbiology laboratory, a high level of AS understanding among staff, established guidelines for empiric prescribing and an easily accessible antibiogram. We identified the following barriers: limited access to clinical pharmacists, physician immunity to change regarding stewardship policies, infrequent antibiotic de-escalation, high physician workload, an incomplete electronic medical record (EMR), inadequate AS programme (ASP) physical visibility and high antibiotic use in the community. CONCLUSIONS: Opportunities for improvement at this institution include increasing accessibility to clinical pharmacists, implementing strategies to overcome physician immunity to change and establishing a more accessible and complete EMR. Our findings are likely to be of use to institutions developing ASPs in lower resource settings.

BACKGROUND: Hospital acquired infections occur at higher rates in low- and middle-income countries, like India, than in high-income countries. Effective implementation of infection control practices is crucial to reducing the transmission of hospital acquired infections at hospitals worldwide. Yet, no comprehensive assessments of the barriers to sustained, successful implementation of hospital interventions have been performed in Indian healthcare settings to date. The Systems Engineering Initiative for Patient Safety (SEIPS) model examines problems through the lens of interactions between people and systems. It is a natural fit for investigating the behavioral and systematic components of infection control practices. METHODS: We conducted a qualitative study to assess the facilitators and barriers to infection control practices at a 1250 bed tertiary care hospital in Haryana, northern India. Twenty semi-structured interviews of nurses and physicians, selected by convenience sampling, were conducted in English using an interview guide based on the SEIPS model. All interview data was subsequently transcribed and coded for themes. RESULTS: Person, task, and organizational level factors were the primary barriers and facilitators to infection control at this hospital. Major barriers included a high rate of nursing staff turnover, time spent training new staff, limitations in language competency, and heavy clinical workloads. A well developed infection control team and an institutional climate that prioritizes infection control were major facilitators. CONCLUSIONS: Institutional support is critical to the effective implementation of infection control practices. Prioritizing resources to recruit and retain trained, experienced nursing staff is also essential.
