Effectiveness of Current Interventions in Curbing HAIs in UK Hospitals

This essay critically examines the effectiveness of current interventions in curbing Healthcare-Associated Infections (HAIs) within the UK. It begins by defining HAIs, outlining their prevalence, types, and associated risks, and highlights their significance as a public health concern. The essay then delves into the current prevention strategies employed in the UK, categorizing them into vertical and horizontal approaches. Vertical strategies, such as active surveillance testing for pathogens like MRSA, are discussed alongside their efficacy and limitations. Horizontal strategies, including hand hygiene, the use of personal protective equipment, decolonization methods, and antimicrobial stewardship, are analyzed in detail. The essay provides real-world examples and discusses the facilitators and barriers to the implementation of these interventions, drawing on policies and research evidence. The conclusion emphasizes the importance of consistent implementation, quality improvement initiatives, and the need for evidence-based recommendations, advocating for a balanced approach that considers both vertical and horizontal strategies to effectively reduce HAIs. It highlights the complexity of managing the evolving epidemiology of multi-drug resistant organisms and the need for continuous adaptation and improvement in infection prevention practices.

Effectiveness of Current Interventions in Curbing Healthcare Associated Infections
(HAIs) within the UK

Introduction
Healthcare-associated infections (HAIs), also called “hospital-acquired infections”, simply
involve infections, which might occur in any patient after his/her admission to the hospital
(Pronovost et. al., 2006). HAIs are infections, which were neither existent nor nurturing
during the admission time (Cole, 2011). Infections developed within the health-care settings,
but demonstrating after discharge together with occupational infections amongst the facility
employees, come under HAIs (Revelas, 2012). Health associated infections have become a
public issue considering their speedy spread, almost in all groups and regions. The health
associated infections are not just restricted to any particular age group or segment, however
include all individuals irrespective of their demographics and particulars (Grave et. al., 2007).
Moreover, commonly taking place HAIs take in Clostridium difficile infections, pneumonia,
central line-associated bloodstream infections, surgical site infections, methicillin-
resistant Staphylococcus aureus (MRSA) infections, urinary tract infections and lastly, VRE
(vancomycin-resistant enterococci) infections, amongst others (Chan et. al., 2007).
Additionally, forces contributing to HAIs as well as the associated expenses take in,
nevertheless are not restricted to, usage of intrusive tools, surgical processes, selection stress
from unnecessary use of antibiotic, contaminated systems of air-conditioning, physical
structure of the facility, recruitment (ratio of nurse to patient), usage of immunosuppressive
agents, fundamental circumstances amongst patients along with their interactions (Glance et.
al., 2011). Further, taking the above discussion into consideration this particular paper
attempts to examine the effectiveness of current interventions in curbing healthcare
associated infections (HAIs) within the UK.
HAIs in the UK
During the beginning stages of the 20th century, the United Kingdom observed noteworthy
scientific progressions on prevention and control (P&C), in spite of substantial regional
differences in healthcare provisions (Safdar and Abad, 2008). The investiture of NHS (the
National Health Service) during the year 1948 witnessed the start of national efforts for
reducing HAI and Staphylococcus aureus epidemics during the period of 1950s placed the
issues to broader public focus (Aga et. al., 2015). During the period of 1960s, the P&C of
healthcare associated infections was positioned as being a vital aspect for healthcare
procedures (Maehara et. al., 2017). This involved the formal formation of infection regulator

as a nursing forte along with the initiation of working groups, journals and conferences.
These activities assisted in raising the issues related to HAI at the political and national level.
At present, HAIP are properly entrenched within national healthcare practices and
institutions; management on surveillance systems are in control of the Public Health England
authority. Additionally, every region within the United Kingdom involves its own HAIP
directed through national public health bodies grounded upon alike practices and principles.
Practice is developed through national evidence-based procedures and wide values of most
suitable practice for integrating them into every-day practice. Further, the below figure
throws light upon the progress of HAIs in the UK over the years (Gould et. al., 2017).
Moving ahead, over the period of past few years, the general strategies for healthcare-
associated infection (HAIs) avoidance have undertaken two conceptually diverse courses
within the UK. Firstly, the vertical approaches intend to trim down colonization, spread of
specific pathogens and infection, mainly by the usage of AST (active surveillance testing) for
identifying carriers, followed through execution of strategies intended towards averting
spread from carriers to some other patients (Aga et. al., 2015). Secondly, horizontal strategies
intend to decrease the threat associated with infections because of a wide range of pathogens
by means of implementing standardized procedures, which don’t rely upon patient-specific
situations.
Vertical Strategies for Preventing HAIs

Vertical strategies make use of activities, which are directed towards some single pathogen or
particular sets of pathogens as well as are frequently grounded upon the outcomes of AST
(Garrouste-Orgeas et. al., 2012). AST is employed for identifying patients who are basically
carriers of such target carriers so that such patients could be secluded from non-carriers and
within few cases, could go through decolonization for eradicating pathogen carriage.
Moreover, this particular strategy has been widely studied for preventing MRSA spread along
with infection (Gould et. al., 2017). The efficiency of AST in averting the spread of MRSA
and infection persists as being controversial and research studies revolving around this topic
have brought about different conclusions. The Dutch national approach for preventing and
controlling MRSA is grounded upon a highly aggressive and proactive approach i.e. search
and destroy intended towards recognizing all carriers of hospitalized MRSA (Huang et. al.,
2013). This procedure needs AST of individuals having epidemiologic connections with
MRSA carriers and segregation of MRSA carriers and staff cohorting who are concerned
about MRSA carriers. Nevertheless, it has been observed that the aggressive approaches like
these might just be cost efficient in fractions of the world having quite low prevalence of
MRSA (Aga et. al., 2015). Since the year 2006, there has been a great decrease in MRSA
bloodstream infections (i.e. from 1.3 percent to below 0.1 percent) together with a 5-fold
decrease in Clostridium difficile infections (i.e. from 2 percent to 0.4 percent) (Aga et. al.,
2015).
Horizontal Strategies for Preventing HAIs
Hand hygiene is considered as being one among the highly significant horizontal approaches
for prevention of HAIs (Parameswaran et. al., 2016). In spite of this, published hand hygiene
adherence rates averaged around 40% in the UK in the year 2017 (Gould et. al., 2017).
Additionally, some studies have highlighted the fact that worldwide gloving could also trim
down MDROs transmission through averting hands contamination of healthcare staff. The
worldwide gloving has been related to noteworthy decrease in all-cause bacteremia along
with central line–related bloodstream contaminations within acute pediatric divisions at the
tiem of respiratory syncytial virus period. However, the effect of global gowning along with
gloving continues to be controversial. It has been discovered that the usage of gowns and
gloves was related with lesser healthcare personnel visits nevertheless enhanced hand
hygiene obedience within both intervention and control ICUs, and no disparity in the threat
associated with adversarial proceedings was observed between intervention and control

patients. Due to the related expenses along with healthcare personnel time needed for
universal use of gowns and gloves, this approach is improbable to be practicable external to
the ICU settings (Maehara et. al., 2012).
Moving ahead, decolonization of all the patients placed within high-risk surroundings by
making use of topical CHG (chlorhexidine gluconate) is another horizontal approach, which
has gained high focus. Moreover, CHG bathing has been observed to trim down the bio-load
of microorganisms upon the patients, the surroundings as well as healthcare personnel hands.
It has been observed that enhanced hand hygiene along with global CHG bathing has
decreased MDROs acquisition taking in MRSA and highlighted that within an environment
wherein high degrees of adherence towards CHG and hand hygiene bathing were continued,
the adding of AST (either conventional or rapid testing) along with carriers segregation did
not additionally trim down the rates of MDRO acquisition. Decolonization by making use of
CHG bathing for preventing CRE spread along with infection has been used with other
infection resistor approaches during outbreak situations. Further, SDD (selective digestive
tract decontamination) is also a widely adopted horizontal approach intended towards
eliminating pathogens carriage for preventing following respiratory tract contaminations.
SDD normally includes topical use of antimicrobial agents (such as tobramycin, polymyxin
and lastly, amphotericin) within the oropharynx as well as into the gastrointestinal area by
means of a nasogastric tube. Few SDD procedures also take in a primary parenteral
antimicrobials course (such as cefotaxime) along with the topical agents.
Taking a step ahead, overuse and misuse of antimicrobials ease MDROs development,
making AS (antimicrobial stewardship) vital horizontal HAI deterrence approach, which
could accompaniment other practices. AS endeavours, idyllically take in interdisciplinary
association intended towards offering cautious and suitable antimicrobial usage for patients
all through the care continuum (Lin et. al., 2017). Moreover, AS has been observed as being
vital in decreasing HAIs rates and the threats of other hostile proceedings arising from the
exposure of antimicrobial agents. Enhancing antimicrobial recommending procedures along
with other infection avoidance approaches has been quite efficient in trimming
down Clostridium difficile infection (CDI) threat within non-outbreak and outbreak
surroundings. Advanced research is required for effectively quantifying the effect of AS upon
MDRO threats (Cristina et. al., 2016). Sufficient cleaning of the healthcare setting is seen as
being a vital horizontal HAI prevention approach (Scott, 2009). Additionally, evidence is

growing that unclean surfaces perform a vital part in the spread of various chief pathogens
taking in Clostridium difficile, MRSA, VRE, Acinetobacter baumannii as well as norovirus.
Further, all these organisms could continue from hours till days within the atmosphere
(McCannon et. al., 2007). Healthcare experts could infect their hands not just via direct
interaction with an infected or colonized person nevertheless also through touching unclean
hospital areas. It has been observed that the rates of MRSA within hospitals have decreased
considerably during the recent years. The private-sector hospitals are supposed to have a
considerably lesser prevalence of HCAI than the NHS hospitals.
Moving ahead, a lot of research has been carried out with respect to spread of HAIs among
people. The above discussion clearly illustrated that although the rate of HAIs in the UK has
fallen considerably but still there prevails the need for taking actions to improve the situation
further. The same has been illustrated by a number of research studies carried out in this area.
Thus, it can be stated that the above discussion corresponds well with the previous research
studies conducted in this sphere. Additional research can be conducted in this area to properly
comprehend additional strategies, which can help in bringing down the rate of HAIs and
eradicating them completely.
Conclusion
To conclude, it can be clearly stated that reliable execution is important for either horizontal
or vertical strategies within the UK. As the fresh data arrives, prevention measures
considered as being efficient must be incorporated into care, applied consistently as well as
continued (Koenig and Truwit, 2006). Quality improvement initiatives could perform a vital
part in enabling change and making sure that execution and intra-institutional transmission
respect local settings. Unintentional impacts need to be predicted and monitored
(Danasekaran et. al., 2014). It is highly significant to acknowledge the fact that there is no
single approach for enhancing procedures. Moreover, local contextual forces are very
important and particular aspects of the execution plan need to be tested and altered by making
use of standard quality enhancement approaches, like ones mentioned in the Model for
Improvement (Spagnolo et. al., 2013).
The present capability for adequately comparing the cost efficiency of vertical and horizontal
HAI prevention approaches or combinations of such approaches all through the healthcare
surroundings is greatly restricted through the nonappearance of vigorous information (Al-

Mulhim et. al., 2014). Provided the progressing epidemiology of MDROs along with the
intricacy of dealing with multiplicity of epidemiologically vital pathogens throughout
heterogeneous healthcare surroundings in the UK, however, it is suggested to use vigorous
quality enhancement methods for ensuring consistent performance of fundamental infection
prevention approach considered to alleviate spread of MDROs along with the infections they
bring about; making sure adherence towards proof-based globally applied HAI prevention
approaches taking in hand hygiene, adequate environmental cleaning and antimicrobial
stewardship; application of other evidence-grounded, horizontal approaches like universal
decolonization within situations where advantages are expected to be greater than the costs
and risks and lastly, making use of AST and lastly, other vertical strategies selectively at the
time when epidemiologically significant pathogens are recently developing and occasional to
a specific institution or area or for controlling particular pathogens outbreaks (Khan et. al.,
2017).
