Health Facilities Readiness to Implement Standard Precautions for Infection Prevention and Control in Tanzania: Lesson Learnt from SARA Reports

Introduction: Standard Precautions are a set of measures applied in the care of all individuals/patients regardless of their infectious status aiming at preventing healthcare workers and patients from infections, preventing environmental contamination and spread of infections to the community. Many health facilities have not implemented them to an acceptable level. The purpose of the study is to report progress of improvement in health facilities readiness to implement standard precautions for infection prevention and control based on SARA reports. Methods: We generated mean scores of all standard precautions each year and calculated their standard deviations, variances and confidence intervals. One-way ANOVA was used to determine if the mean scores were equal. Finally, the trend of improvement in health facilities readiness to implement the standard precautions was generated. Results: A total of nine standard precautions were reported in SARA reports for 2012, 2017 and 2020. The mean scores of the standard precautions were 52.22% in 2012, 64.55% in 2017 and 69.66% in 2020. The overall trend showed an increase in health facilities readiness to implement standard precautions, although the mean scores were not statistically different (p-value 0.3217). Conclusion: SARA surveys conducted in Tanzania in 2012, 2017 and 2020 have shown an overall increase in health facilities readiness to implement standard precautions. Safe final waste disposal was being done in fewest facilities while single-use or auto-disable syringes were in most facilities that were sampled in all years. SARA surveys may be a useful way to evaluate Infection Prevention and Control adherence in health facilities.

Evaluation of the Validity of SARS-CoV-2 Infection Control Measures through Antibody Testing for Employees of a University and Hospital

Introduction: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is spread through person-to-person transmission and has become a global pandemic. At Saitama Medical University Hospital, many medical staff members have been involved in treating patients with COVID-19. The Care Task Force was established in collaboration with physicians, medical staff, and clerical staff in the various hospital departments to strengthen infection control measures based on standard precautions. Methods: To determine the outcome of infection control measures, we administered anti-SARS-CoV-2 antibody tests and questionnaires to all 2461 employees including nonhospital workers, as a local standard, between June 29 and July 10, 2020. Results: Among the hospital workers, 698 (33.99%) had contact with patients with COVID-19 and 325 healthcare workers worked in specialized wards for the COVID-19, intensive care unit, and high-fever outpatient clinics. Positive for the anti-SARS-CoV-2 antibody were only 4 (0.16%) employees. Among them, the past histories of two employees were unknown, while the other two had a history of COVID-19 before the test and were not involved in the medical care of COVID-19 patients at our hospital. Conclusion: It is the first study assessing the seropositive rate in Saitama-prefecture, a bed-town of Tokyo. Compared with the local standard, we found that health care workers are not at risk for viral droplet transmission, especially with SARS-CoV-2 and even with the current pandemic, with infection control measures based on standard precautions. Based on our findings and with no clusters formed in our university and hospital, we continued current infection control measures.

Results:Post-intervention,the percentage of studied nurses who always practiced increased in every item of TB infection control practice(6 items) and standard precaution(9 items) when compared with the preintervention period.Both mean scores were significantly higher than those before intervention(5.0±1.0 vs 4. 4±1.1,and 7.6±1.3 vs 6.7±1.5,P【0.001,respectively).As well as,bacterial and fungal counts in air samples collected from every studied ward decreased after implementing the intervention,for example, mean of bacterial counts in OPD decreased from 387.8±249.5 cfu/m^3 to 194.4±134.3 cfu/m^3.Additionally, there was no air sample with high level of bacterial and fungal counts,whereas,3.7 -22.2%of air samples collected before intervention had high level of bacterial counts(】500 cfu/m^3).Conclusion:Two-day training program and management of the ward environment could improve the scores of TB infection control practices and the standard precaution among studied nurses and reduce the microbial counts in air samples collected from the studied wards.

Factors Associated with Compliance with Infection Control Guidelines in the Management of Labour by Healthcare Workers at Mulago Hospital, Uganda

Globally, infections acquired during childbirth contribute to one tenth of the maternal deaths annually [1] [2]. Factors predisposing to high risks of puerperal infections include non-compliance with Standard Precautions of Infection Control (SPIC), unhygienic births by unskilled birth attendants, multiple vaginal examinations, prolonged labour and premature rapture of membranes [1]. The main purpose of this study was to determine factors associated with compliance to standard precautions of infection control the management of labour by healthcare workers in Mulago Hospital to generate information, which may be used in infection control and prevention practices. A cross-sectional study utilizing a quantitative approach was conducted among 115 healthcare workers. Consecutive sampling was done to include respondents in the study. Data were collected by direct observation and researcher administered questionnaires. Data were coded and entered into the computer using SPSS version 20 with programmed quality control checks. Descriptive data analyses, frequencies, cross tabulations and logistic regression analysis were the major statistical methods used. 103 healthcare workers were involved in the study, where 74% were females. Overall compliance was at 52%, although it varied across domains. The majority of the healthcare workers (95.1%) did not comply with hand hygiene. Being a male was associated with low compliance scores a cross most domains. One of the hospital factors which was significantly associated with compliance to hand hygiene was having had an in-service training with p = 0.008 and p = 0.012 at multivariate analysis. Overall compliance to standard precautions of infection control was low compared to the Centre for Disease Control (CDC) recommendation. The findings in this study provide insight into individual and hospital related factors associated with compliance with standard precautions of infection control in the management of labour. There is an urgent need to put up interventions to improve on compliance with SPIC in management of labour among all healthcare workers.

External Validation of SENIC and NNIS Scores for Predicting Wound Infection in Colorectal Surgery

Objective: We aimed to identify the ratio of Surgical Site Infection (SSI) and also the validity of the National Nosocomial Infection Survellance (NNIS) and Study on the Efficacy of Nosocomial Infection Control (SENIC) risk indexes in colorectal surgery, among Turkish population. Background: Some problems have been reported with the power of NNIS risk index to predict the risk of surgical site infection. We aimed to validate theNNIS and SENIC risk indexes in colorectal surgery. Methods: Between January 2003 and December 2006, surgical site ?nfection survellance was performed to 107 patient who undergo colorectal surgery with NNIS and SENIC risk scales. The mean patient age was 48 years (range, 17 to 86), and 61.7% of the group (66) was female. For this patient cohort, 6 (5.6%) were diagnosed with incisional SSI. While the mean Body Mass Index (BMI) of all patients was 26.6;mean value of BMI among the patiens with SSI was 27.8.Results: 6 insicional surgical site infection were observed during the study. According to Receiver Operating Characteric (ROC) curve analyze neither NNIS with avalue of 0.70, nor SENIC with a value of 0.67 are perfect risk indexes. Conclusion: As a result both NNIS and SENIC ?s a good risk indexes but not perfect. Scarcely when NNIS and SENIC is used together to predict the SSI they forecast the development of infection better. But there is a lot of other factors that effect the development of SSI, so for excellent surveillance risk index those factors known by everyone must be added to risk index scales.

A Blockchain-Based Life-Cycle Environmental Management Framework for Hospitals in the COVID-19 Context

During the coronavirus disease 2019 (COVID-19) emergency, many hospitals were built or renovated around the world to meet the challenges posed by the rising number of infected cases. Environmental management in the hospital life cycle is vital in preventing nosocomial infection and includes many infection control procedures. In certain urgent situations, a hospital must be completed quickly, and work process approval and supervision must therefore be accelerated. Thus, many works cannot be checked in detail. This results in a lack of work liability control and increases the difficulty of ensuring the fulfillment of key infection prevention measures. This study investigates how blockchain technology can transform the work quality inspection workflow to assist in nosocomial infection control under a fast delivery requirement. A blockchain-based life-cycle environmental management framework is proposed to track the fulfillment of crucial infection control measures in the design, construction, and operation stages of hospitals. The proposed framework allows for work quality checking after the work is completed, when some work cannot be checked on time. Illustrative use cases are selected to demonstrate the capabilities of the developed solution. This study provides new insights into applying blockchain technology to address the challenge of environmental management brought by rapid delivery requirements.
