Effectiveness of national and subnational interventions for prevention and control of health-care-associated infections in acute hospitals in high-income and upper-middle-income counties: a systematic review update

The burden of healthcare-associated infections in New Zealand public hospitals 2021

BACKGROUND

There are no contemporary data on the burden of healthcare-associated infections (HAIs) in New Zealand.

OBJECTIVES

To estimate the economic burden of HAIs in adults in New Zealand public hospitals by number and monetary value of bed days lost; number of deaths, number of life years lost, and the monetary value (in NZ dollars); Accident Compensation Commission (ACC) HAI treatment injury payments; and disability-adjusted life years (DALYs).

METHODS

The annual incidence rate was calculated from the observed prevalence of HAIs in New Zealand, and length of patient stays. Total HAIs for 2021 were estimated by multiplying adult admissions by incidence rates. The excess length of stay and mortality risk attributed to those with HAI was calculated using a multistate model. Payments for treatment injuries were obtained from the ACC. DALYs for HAIs were estimated from the literature.

RESULTS

The incidence rate of HAI was 4.74%, predicting 24,191 HAIs for 2021, resulting in 76,861 lost bed days, 699 deaths, with 9,371 years of life lost (YoLL). The annual economic burden was estimated to be $955m comprised of $121m for lost bed days, $792m for cost of YoLL, and $43m ACC claims. There were 24,165 DALY which is greater than many other measured injuries in New Zealand, eg motor vehicle traffic crashes with 20,328 DALY.

CONCLUSIONS

HAIs are a significant burden for patients, their families, and the public health system. Preventive guidelines for many HAIs exist and a strategic plan is needed to reduce HAIs in New Zealand.

Evaluating national infection prevention and control minimum requirements: evidence from global cross-sectional surveys, 2017-22

BACKGROUND

WHO infection prevention and control (IPC) minimum requirements provide standards to reduce the risk of infection during health-care delivery. We aimed to investigate the global implementation of these requirements at national levels and the progress of doing so across 2021-22 compared with 2017-18 to identify future directions for interventions.

METHODS

National IPC focal points were invited to complete an online survey measuring IPC minimum requirements from July 19, 2021, to Jan 31, 2022. The primary outcome was the proportion of countries meeting IPC minimum requirements. Country characteristics associated with this outcome were assessed with beta regression. Subset analyses were conducted to compare the 2021-22 indicators with a WHO IPC survey conducted in 2017-18 and to assess the correlation of the proportion of IPC minimum requirements met with the results of other WHO metrics.

FINDINGS

106 countries (ie, 13 low income, 27 lower-middle income, 33 upper-middle income, and 33 high income) participated in the survey (56% response rate). Four (4%) of 106 met all IPC minimum requirements. The highest scoring IPC core component was multimodal improvement strategies and the lowest was IPC education and training. The odds of meeting IPC minimum requirements was higher among high-income countries compared with low-income countries (adjusted odds ratio 2·7, 95% CI 1·3-5·8; p=0·020). Compared with the 2017-18 survey, there was a significant increase in the proportion of countries reporting an active national IPC programme (65% to 82%, p=0·037) and a dedicated budget (26% to 44%, p=0·037). Evaluation of the IPC minimum requirements compared with other survey instruments revealed a low positive correlation.

INTERPRETATION

To build resilient health systems capable of withstanding future health threats, urgently scaling up adherence to WHO IPC minimum requirements is essential.

Central aspects when implementing an electronic monitoring system for assessing hand hygiene in clinical settings: A grounded theory study

Background

New technologies, such as electronic monitoring systems, have been developed to promote increased adherence to hand hygiene among healthcare workers. However, challenges when implementing these technologies in clinical settings have been identified.

Aim

The aim of this study was to explore healthcare workers' experiences when implementing an electronic monitoring system to assess hand hygiene in a clinical setting.

Method

Interviews with healthcare workers (registered nurses, nurse assistants and leaders) involved in the implementation process of an electronic monitoring system (n = 17) were conducted and data were analyzed according to the grounded theory methodology formulated by Strauss and Corbin.

Results

Healthcare workers' experiences were expressed in terms of leading and facilitating, participating and contributing, and knowing and confirming. These three aspects were merged together to form the core category of collaborating for progress. Leaders were positive and committed to the implementation of the electronic monitoring system, endeavouring to enable facilitation and support for their co-workers (registered nurses and nurse assistants). At the same time, co-workers were positive about the support they received and contributed by raising questions and demands for the product to be used in clinical settings. Moreover, leaders and co-workers were aware of the objective of implementing the electronic monitoring system.

Conclusion

We identified dynamic collective work between leaders and co-workers during the implementation of the electronic monitoring system. Leadership, participation and knowledge were central aspects of enhancing a collaborative process. We strongly recommend involving both ward leaders and users of new technologies to promote successful implementation.

Challenges and success stories of the implementation of infection control and antimicrobial stewardship strategies: proceedings of the 5th Global Ministerial Summit on Patient Safety, 2023

The 5th edition of the Global Ministerial Summit on Patient Safety was held in Montreux, Switzerland, in February 2023, delayed by three years due to the COVID-19 pandemic. The overarching theme of the summit was "Less Harm, Better Care - from Resolution to Implementation", focusing on the challenges of implementation of infection prevention and control (IPC) strategies as well as antimicrobial stewardship programs (ASP) around the world. IPC strategies and ASP are of increasing importance due to the substantial burden of healthcare-associated infections and antimicrobial resistance threatening patient safety. Here, we summarize countries' and regional experiences and activities related to the implementation of IPC strategies and ASP shared at the meeting. Full implementation of effective programs remains a major challenge in all settings due to limited support by political and healthcare leaders, and human and financial constraints. In addition, the COVID-19 pandemic challenged already well-established programs. By enforcing sustained implementation by dedicated, cross-disciplinary healthcare personnel with a broad skill set, a reduction in healthcare-associated infections and multidrug-resistant pathogens can be achieved, leading ultimately to improved patient safety.
