Incidence, accuracy, and barriers of diagnosing healthcare-associated infections: a case study in southeast Iran.

BACKGROUND: Healthcare-associated infections (HAIs) are a threat to patients. Accurate surveillance is required to identify and prevent HAIs. To estimate the incidence rate, report the accuracy and identify the barriers of reporting HAIs using a mixed-method study. METHODS: In this quantitative study, we externally evaluated the incidence rate and accuracy of the routine surveillance system in one of the main hospitals by an active follow-up of patients from September to December 2021. We used in-depth interviews with 18 experts to identify the barriers of the routine surveillance system. RESULTS: Among 404 hospitalized patients, 88 HAIs were detected. The estimated rate of HAIs was 17.1 (95% Confidence Intervals 95: 14.1, 21.1) per 1000 patient-days follow-up. However, in the same period, 116 HAIs were reported by the routine surveillance system, but the agreement between the two approaches was low (sensitivity = 61.4%, specificity = 82.6%, negative predictive value = 89.7%, and positive predictive validity = 46.5%). The minimum and maximum positive predictive values were observed in urinary tract infection (32.3%) and surgical site infection (60.9%). The main barrier of reporting HAIs was lack of cooperation in reporting HAIs by infection control link nurses and laboratory supervisors. CONCLUSIONS: The discrepancy between the longitudinal study findings and the routine surveillance might be related to the inaccessibility of the surveillance system to clinical information of patients. In this regard, decreasing the barriers, increasing the knowledge of infection control nurses and other nurses, as well as the development of hospital information systems are necessary.

Barriers and Problems in Implementing Health-Associated Infections Surveillance Systems in Iran: A Qualitative Study.

Background: Healthcare-associated infections (HAIs) are among the most critical challenges for patients and healthcare providers. To achieve the goals of the surveillance system, it is necessary to identify its barriers and problems. This study aimed to identify the barriers and problems of the surveillance system for HAIs. Methods: This qualitative study was conducted using the content analysis method to investigate the challenges of this surveillance system from the perspective of 18 infection control nurses from hospitals in different cities of Iran with work experience of 1 to 15 years. Data were collected through semi-structured interviews and analyzed using the Lundman and Graneheim qualitative content analysis method. Results: In this study, we found 2 categories and 7 subcategories. Two categories were barriers related to human resources and organizational barriers to infection control. The 7 subcategories included weakness of medical staff in adherence to health principles, obstacles related to patients, high workload and insufficient motivation, lack of staff knowledge, lack of human resources, functional and logistical weaknesses, and weaknesses in the surveillance system. Conclusion: To reduce problems and improve HAIs reporting, the HAIs surveillance system needs the support of health system officials and managers. This administrative and support focus can establish the framework for removing and lowering other barriers, such as the number of reported cases, physician and staff noncooperation, and the prevalence of HAIs. It can also bring HAIs cases closer to reality.

HIV testing among incarcerated people with a history of HIV-related high-risk behaviours in Iran: Findings from three consecutive national bio-behavioural surveys.

BACKGROUND: Incarcerated people are at a disproportionate risk of contracting HIV. We estimated the prevalence and correlates of HIV testing among incarcerated people with a history of HIV-related high-risk behaviours in Iran. METHODS: Data for this analysis were obtained from three consecutive nationwide bio-behavioural surveillance surveys of a random sample of incarcerated people in 2009 (n = 5953), 2013 (n = 5490), and 2017 (n = 5785). History of testing for HIV in the last 12 months was the primary outcome variable. HIV testing was examined among those with a history of HIV-related high-risk behaviours (i.e., having multiple sex partnerships, injection drug use practices, or a history of having a tattoo). The outcome variable was divided into three categories: Never tested for HIV, ever tested for HIV inside the prison in the last 12 months, and ever tested for HIV outside the prison in the last 12 months. We used multivariable multinomial logistic regression models to examine factors associated with HIV testing. RESULTS: Overall, 8,553 participants with a history of HIV-related high-risk behaviors with valid responses to the HIV testing question were included in the analysis. Although HIV testing inside prison has increased (23% [2009], 21.5% [2013], and 50.3% [2017]: P-value < 0.001), the prevalence of HIV testing outside prison has decreased (7.7% [2009], 7.5% [2013], 4.1% [2017]: P-value < 0.001) over time. Our multivariable multinomial regression model showed older age (Relative-risk ratio [RRR]: 1.24, 95% Confidence Intervals [CI]: 1.05, 1.47), history of the previous incarceration (RRR: 1.46, 95% CI: 1.24, 1.71), currently receiving methadone maintenance therapy inside prison (RRR: 2.09, 95% CI: 1.81, 2.43), having access to condoms inside prison (RRR: 1.42, 95% CI: 1.20, 1.68) and sufficient HIV knowledge (RRR: 1.74, 95% CI: 1.47, 2.05) were significantly associated with an increased probability of having an HIV test in the last 12 months inside prison. CONCLUSION: HIV testing among high-risk Iranian prisoners has increased from 2009 to 2017. However, HIV testing remains considerably low, and half of the incarcerated people with a history of HIV-related high-risk behaviours had never tested for HIV inside prison. Evidence-based programs are needed to optimize HIV testing inside and outside prisons and identify those at greater risk of HIV.

Efficacy and Safety of a Protein-Based SARS-CoV-2 Vaccine: A Randomized Clinical Trial.

Importance: The protein-based SARS-CoV-2 vaccines FINLAY-FR-2 (Soberana 02) and FINLAY-FR-1A (Soberana Plus) showed good safety and immunogenicity in phase 1 and 2 trials, but the clinical efficacy of the vaccine remains unknown. Objective: To evaluate the efficacy and safety of a 2-dose regimen of FINLAY-FR-2 (cohort 1) and a 3-dose regimen of FINLAY-FR-2 with FINLAY-FR-1A (cohort 2) in Iranian adults. Design, Setting, and Participants: A multicenter, randomized, double-blind, placebo-controlled, phase 3 trial was conducted at 6 cities in cohort 1 and 2 cities in cohort 2. Participants included individuals aged 18 to 80 years without uncontrolled comorbidities, coagulation disorders, pregnancy or breastfeeding, recent immunoglobulin or immunosuppressive therapy, and clinical presentation or laboratory-confirmed COVID-19 on enrollment. The study was conducted from April 26 to September 25, 2021. Interventions: In cohort 1, 2 doses of FINLAY-FR-2 (n = 13 857) or placebo (n = 3462) were administered 28 days apart. In cohort 2, 2 doses of FINLAY-FR-2 plus 1 dose of FINLAY-FR-1A (n = 4340) or 3 placebo doses (n = 1081) were administered 28 days apart. Vaccinations were administered via intramuscular injection. Main Outcomes and Measures: The primary outcome was polymerase chain reaction-confirmed symptomatic COVID-19 infection at least 14 days after vaccination completion. Other outcomes were adverse events and severe COVID-19. Intention-to-treat analysis was performed. Results: In cohort 1 a total 17 319 individuals received 2 doses and in cohort 2 5521 received 3 doses of the vaccine or placebo. Cohort 1 comprised 60.1% men in the vaccine group and 59.1% men in the placebo group; cohort 2 included 59.8% men in the vaccine group and 59.9% in the placebo group. The mean (SD) age was 39.3 (11.9) years in cohort 1 and 39.7 (12.0) years in cohort 2, with no significant difference between the vaccine and placebo groups. The median follow-up time in cohort 1 was 100 (IQR, 96-106) days and, in cohort 2, 142 (137-148) days. In cohort 1, 461 (3.2%) cases of COVID-19 occurred in the vaccine group and 221 (6.1%) in the placebo group (vaccine efficacy: 49.7%; 95% CI, 40.8%-57.3%) vs 75 (1.6%) and 51 (4.3%) in cohort 2 (vaccine efficacy: 64.9%; 95% CI, 49.7%-59.5%). The incidence of serious adverse events was lower than 0.1%, with no vaccine-related deaths. Conclusions and Relevance: In this multicenter, randomized, double-blind, placebo-controlled, phase 3 trial of the efficacy and safety of FINLAY-FR-2 and FINLAY-FR-1A, 2 doses of FINLAY-FR-2 plus the third dose of FINLAY-FR-1A showed acceptable vaccine efficacy against symptomatic COVID-19 as well as COVID-19-related severe infections. Vaccination was generally safe and well tolerated. Therefore, Soberana may have utility as an option for mass vaccination of the population, especially in resource-limited settings, because of its storage condition and affordable price.

Acinetobacter endocarditis: a rare nosocomial infection of native heart valves.

Acinetobacter baumannii is an opportunistic bacterial pathogen predominantly associated with hospital-acquired infections. Here we present a case of infective endocarditis of native Mitral and Aorta valves caused by A. baumannii in a 73-year-old man. He underwent surgical excision and Pathologic specimen showed A. baumannii growth after 48 hours that was extensively drug-resistant (XDR). He was treated with colistin and tigecycline. Finally, he discharged with no important complication. To our best knowledge, it is the first case of Acinetobacter endocarditis has ever been reported in Iran. Although XDR A. baumannii is a life-threatening pathogen, proper and timely treatment can be life-saving.

Evaluation of hepatitis C, hepatitis B, and HIV virus Serology pandemic in thalassemia patients of Shahid Mohammadi Hospital of Bandar Abbas, Iran.

INTRODUCTION: Thalassemia patients are prone to the hepatitis C, B, and HIV virus, due to their constant need to receive blood transfusions. Therefore, this research was aimed to determine the epidemic of the aforementioned diseases in thalassemia patients of Shahid Mohammadi Hospital of Bandar Abbas, Iran. METHODS: This cross-sectional study was carried out on thalassemia patients visiting the Thalassemia Hospital of Bandar Abbas from March 21, 2014, to March 22, 2015. Checklists were used to collect the data. HBS-Ag, HCV-Ab, and HIV-Ab tests have been registered for hepatitis B, hepatitis C, and HIV virus, respectively. The data were analyzed using SPSS 19 by Mann-Whitney U test, chi-square test, and independent samples t-test. RESULTS: Among 587 records administered into the research, 280 individuals (47.7 %) were men and (52.3 %) were female. The average age of participants was 18.01 ± 9.31 years. The youngest was 1 years old, and the oldest was 46 years old. Four patients under the study (0.7 %) were positive for HBV; 60 (10.2 %) were HCV positive. However, no one in the study was diagnosed HIV positive. In the case of spread, there was no significant difference regarding age and sex in HBV patients. However, in HCV patients, significant differences were found (p=0.044 for gender and p=0.001 for age). CONCLUSION: In thalassemia, hepatitis C had the highest rate of spread. According to the screening, it was much anticipated that the trend should be falling, but the results show the contrary. Hence, it is recommended that more precise methods such as PCR be used.

Hepatitis C and G Virus Infection Prevalence Among Hemodialysis Patients and Associated Risk Factors in the Hormozgan Province of Southern Iran.

BACKGROUND: Infection with blood-borne viruses including hepatitis C (HCV) and hepatitis G (HGV) viruses is a substantial health problem. Varying prevalences of these infections in different studies reflect the role of predisposing risk factors in different countries or even different regions of a country. OBJECTIVES: The objective of the present survey was to assess the prevalences of HCV and HGV virus infections among hemodialysis (HD) patients in Bandar Abbas, Hormozgan, Iran, 2015. METHODS: A total of 149 subjects with chronic renal failure undergoing HD at Shahid Mohammadi hospital in the Hormozgan province of southern Iran from January 1, 2015 to March 31, 2015 were evaluated for anti-HCV and antibodies against HGV E2 glycoprotein by census sampling method. Thereafter, all of the specimens were evaluated for molecular assays using polymerase chain reaction (PCR) and other techniques. Investigated data were recorded for each participant in a pre-designed data collection sheet. All statistical analyses were conducted using the Statistical Package for the Social Sciences (SPSS) version 19 for Windows by t-test and chi-square test (χ2). RESULTS: The mean age of patients was 56.23 ± 12.35 years (minimum age 18, maximum age 85). Both kinds of assays determined that five (3.36%) patients were HCV positive, whereas no HGV positives were diagnosed. The prevalence of HCV is associated with longer duration of HD (P value = 0.008), history of blood transfusion (P value = 0.037) and drug addiction (P value = 0.035). CONCLUSIONS: History of drug addiction and/or blood transfusion and longer duration of HD treatment were the main risk factors determining the prevalence of HCV infection in the Hormozgan province of southern Iran in 2015. However, the values observed in the present investigation reflect the effective management techniques imposed by healthcare authorities and relevant organizations in recent years.

Hepatitis Viruses B and D and Human Immunodeficiency Virus Infections in Hemodialysis Patients in the South of Iran: Prevalence and Genotypes.

BACKGROUND: Hepatitis B virus (HBV), hepatitis D virus (HDV), and human immunodeficiency virus (HIV) are transmitted by blood transfusion. Thus, hemodialysis (HD) patients are more prone to become the carriers of these infections due to their treatment demands. OBJECTIVES: The aim of this study was to assess the prevalence of HBV and HIV infections among HD patients in Bandar Abbas, Iran, 2015. PATIENTS AND METHODS: A total of 153 patients with chronic renal failure undergoing HD at Shahid Mohammadi hospital in Bandar Abbas were examined for hepatitis B surface antigen (HBsAg), anti- hepatitis C virus, and anti-HIV over a period of 2 months. Thereafter, all of the specimens were evaluated for HBV-DNA, HDV-RNA and HIV-RNA using polymerase chain reaction (PCR) and further techniques. All statistical analyses were carried out using SPSS version 12 for Windows with the t-test and chi-square (χ(2)) test. RESULTS: Both kinds of assay determined that nine (5.88%) patients were HBV positive (HBsAg-positive), whereas no HIV- and HDV-positive patients were diagnosed. All of the diagnosed HBV samples belonged to genotype D; the prevalence of HBV is associated with age, duration of HD, history of blood transfusion, and using shared HD devices. CONCLUSIONS: In conclusion, the prevalence of HBV infection was low in the south of Iran, but genotype D represented the major HBV genotype in this population. Among the variables, age, duration of HD, history of blood transfusion, and using shared HD devices influenced the prevalence of HBV among HD patients.

Sharp Injuries Among Medical Students.

INTRODUCTION: Sharp injuries threaten the health of healthcare employees. They cause the transmission of many diseases such as hepatitis B and C, AIDS, etc., which can increase the associated costs associated with them. The aim of this study was to investigate the frequency of sharp injuries among the students of Hormozgan University of Medical Sciences. METHOD: This cross-sectional study was conducted during 2012-2013 in Hormozgan University of Medical Sciences, IR Iran. The target population consisted of the medical, nursing, midwifery, operating room technician, and medical laboratory students in the 2012-2013 academic year. Census sampling was conducted, and accordingly, 500 students participated in the study Data was collected using modified questionnaire of the University of San Diego's injury report form. The collected data were entered into SPSS V.19 and analyzed using descriptive statistical tests. FINDINGS: Finally 377 students (75.4%) returned the questionnaire. Among the studied students, 184 students (39.3%) had had sharp injuries. The frequency of damaging Vein puncture was the most common mechanism of injury DISCUSSION & CONCLUSION: The prevalence of sharp injuries is high among students which can increase the risk of disease and its subsequent risks, and thus, increase the cost and stress among students. It seems that holding workshops and increasing students' awareness and skills to face these risks can be effective in mitigating them.
