Challenges for adherence to bacterial resistance actions in large hospitals

Desafíos para la adherencia a las acciones de resistencia bacteriana en grandes hospitales

ABSTRACT

Objectives:

to identify the challenges to actions to contain bacterial resistance.

Methods:

cross-sectional study, carried out in 30 large-sized hospitals in Minas Gerais, from 2018 to 2019. The professionals were interviewed, and the environment and actions to prevent bacterial resistance were observed.

Results:

regarding the knowledge of health care professionals about the measures of bacterial resistance prevention, 78.3% did not correctly describe the five moments of hand hygiene, and 76.6% did not correctly describe the measures to control bacterial resistance. The simple hygiene of hands, followed by alcohol rubbing was predominant (48.3%) among workers, and soap dispensers were next to alcohol dispensers in 58.3% of the nursing stations in care units.

Conclusions:

the insufficient knowledge from the professionals, which is a failure related to the physical structure and to personal protection equipment, are factors that difficult the adherence to measures to contain bacterial resistance in hospitals.

INTRODUCTION

Health care-associated infections (HAI) are among the most recognized adverse effects in the world, since this type of health problem is not only avoidable, but also frequent, threatening the safety of patients and representing a high unnecessary cost to the health system11 Ministério da Saúde (BR).

. Respiratory, urinary tract, bloodstream, and surgical infections are the most frequently notified HAIs in the health services22 Mello MS.

.

In the hospital environment, most bacteria that cause HAIs are resistant to at least one of the antimicrobial agents used for the treatment of patients. In Europe, one in every three infections in hospitals involves antibiotic-resistant bacteria as causing agents22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

.

The HAIs associated to resistant bacteria take place throughout the units of assistance within the hospitals. However, they have been recorded more frequently in patients of Intensive Care Units (ICUs). This finding is largely due to the profile of ICU patients, who have serious base illnesses22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

.

The excessive and unnecessary or mistaken exposure to antimicrobial agents leads bacteria to become resistant, which can happen due to changes in their genetic material, the induction of chromosome mutations, or the acquisition of resistant genetic material, which can be transferred between different genders or species of bacteria22 Mello MS.

However, in addition to genetic mechanisms of bacterial resistance, it must be considered that resistant bacteria can also be disseminated by the hands of health professionals who get in touch with colonized or infected patients or with the environment or surfaces near these patients22 Mello MS.

https://online.unisc.br/seer/index.php/e...
, limits the transmission of resistant microorganisms. This, in turn, reduces the number of preventable infections, reducing morbimortality in health services22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

In this setting, in which measures that are relatively simple to implement, can contribute to prevent the dissemination and emergence of resistant microorganisms. There are three essential guidelines strongly recommended by national and international protocols: hand hygiene, the rational use of antimicrobial agents, and the adherence to standard plus contact precautions by health professionals22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

https://www.cdc.gov/niosh/docket/archive...
.

Recognizing the worldwide impact of bacterial resistance in public health, the World Health Organization (WHO) has established many programs that seek to contain this health problem, aiming to make rational use of antimicrobial agents in human and animal health, to reduce infections through preventive measures, raise awareness about bacterial resistance in the world, and encourage researches that seek to increase the investment in new drugs and health solutions22 Mello MS.

.

From this perspective, health workers are key-players to help reaching these goals, since the potential paths towards controlling the dissemination of bacterial resistance go through the knowledge and behavior of these professionals, who must adopt the recommendations22 Mello MS.

OBJECTIVES

To identify the difficulties to adhere to actions to contain bacterial resistance in large hospitals in Minas Gerais.

METHODS

Ethical aspects

This study is part of the project “Panorama of Global Challenges from the World Health Organization for the Safety of Patients in Large-Sized Hospitals in Minas Gerais”, submitted and approved by the Research Ethics Committee of the Universidade Federal de Minas Gerais (COEP/UFMG).

Design, period, and place of study

This is a cross-sectional observational study in which factor and effect were analyzed in a single historical moment. The study was carried out in Minas Gerais, from February 2018 to April 2019. The instrument used to guide the methodology of this research was the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE).

Population; criteria of inclusion and exclusion

To select the establishments, large general hospitals from Minas Gerais were listed. According to the National Register of Health Establishments (CNES), 542 hospitals were identified as general hospitals; 32 of them were classified as large. The term “general hospital” is here understood as referring to hospitals that attend to many areas, while any hospital which has from 150 to 299 beds was considered to be large, according to Decree No. 2.224/GM22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

http://www.sbccv.org.br/medica2-old/down...
. For the establishment to be included in the study, the following criteria were defined: large-sized general hospitals located in Minas Gerais, in one of the health macro-regions defined by the state. Specialized hospitals, as well as those with less than 150 beds, were excluded.

The eligible hospitals in the capital of the state, Belo Horizonte, were invited to participate by the Municipal Health Secretariat; the others were invited by the State Health Secretariat. Both secretariats were partners in the conduction of the study, due to their interest in finding out about the theme. The representative of all hospitals invited received clarifications about the objectives of the study and was notified that the visit was not an inspection, but targeted at designing a panorama about how hospitals have been conducting their actions, promotion, and practice of patient safety policies22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

The agreement of the institution to the visit was understood as acceptance to participate in the study. The scheduling was done according to the availability of the institution, and the acceptance was voluntary and anonymous, with no financial benefit or coercion. The interviewees were aware that they could abandon participation at any point in time, information which was reinforced during the visit and detailed in the Free and Informed Consent Form22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

30 large hospitals from Minas Gerais participated in the study. After the legal representatives of each institution gave their consent, in-person interviews were carried out with the coordinators of the Hospitalization Units (HUs) and of the ICUs. Simultaneously, the following elements were observed: the adoption of bacterial resistance prevention and control measures by the multiprofessional teams in the care units of the hospitals; and the physical structure of the hospitals, assessed using a situational diagnosis.

The data collection team was made up by researchers from the nursing school of the Universidade Federal de Minas Gerais, in addition to sanitary surveillance professionals from the Municipal Health Secretariat (SMS), when the hospital was in the capital, or sanitary surveillance professionals from the State Health Secretariat (SES), when the hospital was elsewhere in the State22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
. In each participating hospital, 1 professional was interviewed, adding up to 30 in each assistance unit, a total of 60 professionals.

Study protocol

The study used structured questionnaires, based on recommendations proposed by the Centers for Disease Control and Prevention (CDC)88 Centres for Disease Control and Prevention. Guideline for isolation precautions: preventing transmission of infectious agents in healthcare settings [Internet]. 2007 [cited 2019 May 17]. Available from: https://www.cdc.gov/niosh/docket/archive/pdfs/NIOSH-219/0219-010107-siegel.pdf
https://www.cdc.gov/niosh/docket/archive...
. They were translated into Portuguese and previously tested in a pilot study. This aimed at validating the instruments, and the data obtained is not presented in this study. Data was collected following two simultaneous stages, as described in Chart 1.

Chart 1
Stages of the conduction of the study

To evaluate moments of hand hygiene, more than one professional was monitored and observed during the practice of the five moments of hand hygiene. The choice of these professionals took place according to the activities that they were performing at the moment of data collection.

Data analysis

The data collected was analyzed using the software Statistical Package for the Social Sciences (SPSS), version 22.0, using descriptive statistics to characterize the population studied, including the calculation of absolute and relative frequencies, central tendency and dispersion measures for quantitative variables22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

RESULTS

When the coordinators (all of them nurses) of the care units were questioned about the importance of bacterial resistance in their sectors, 100% (n = 60) informed that it is a very relevant issue; 50% (n = 15) in the HUs and 42.2% (n = 13) in the ICUs said that they knew the practices recommended by the WHO to control bacterial resistance22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

Table 1
Knowledge of the nursing coordinators of the Hospitalization Units and Intensive Care Units (N = 60) of the large hospitals from the state of Minas Gerais (n = 30) who participated in the study, Belo Horizonte, Minas Gerais, Brazil, 2019

Among the measures that difficult controlling bacterial resistance in the clinical practice, 60% (n = 36) professionals from both units demonstrated low adherence to hand hygiene, followed by an insufficient adherence to standard plus contact precautions (46.7%. n = 14) in the ICUs and (43.3%; n = 13) in the HUs22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

The lack of criteria for the prescription of antibiotics (15%; n = 9), the difficulties related to supplies and equipment (13.3%; n = 8), the issues related to personnel sizing and turnover (13.13%; n = 8), the cleanliness of the environment (6.6%; n = 4), the flaws in the delivery of results by laboratories (5%; n = 3), and the indication for unnecessary invasive procedures (3.3%; n = 2) were also pointed out as elements that make bacterial resistance more difficult in the hospitals22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

When questioned about the most common type of hand hygiene among professionals in both units, simple hand hygiene was mentioned in 55% (n = 33) of units. Regarding the type of sanitization adopted by workers right before handling patients, in cases where their hands were visibly dirty or uncontaminated, 63.3% (n = 19) from the ICUs and 53.3% (n = 15) from the HUs answered that they rub their hands using alcohol 70%22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

Among the factors that difficult adherence to hand hygiene in clinical practice, which the workers selected from multiple-choice questionnaires, 51.7% (n = 31) chose the hurry, caused by the lack of personnel and work overload; 46.7% (n = 28) mentioned individual cultural aspects of the workers, such as biosafety culture and not believing in the efficacy of this procedure; 8.3% (n = 5), the malfunctioning of the dispensers; 6.6% (n =4), the lack of supplies and materials for hand hygiene and a physical structure that required moving to reach the alcohol for hand rubbing; and 1.6% (n = 1) mentioned the low quality of the products, that risked causing allergic reactions22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

Although nurses reported that simple hand hygiene was the most common method, it was found, through a situational diagnosis, that the predominant type of hygiene was simple hand hygiene followed by rubbing alcohol, as observed in specific situations in both sectors and described in Table 2 22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

.

Table 2
Hand hygiene, according to its five moments, as observed in the assistance units (N = 60) of large hospitals from Minas Gerais (n = 30) that participated in the study, Belo Horizonte, Minas Gerais, Brazil, 2019

Through the situational diagnosis in the health care units, it was possible to see aspects of the infrastructure and supplies that favored the adherence to hand hygiene measures, and standard and isolation precautions, as presented in Table 3 22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

Table 3
Infrastructure of the assistance units (N = 60) of large-sized hospitals from Minas Gerais (n = 30) that participated in the study, Belo Horizonte, Minas Gerais, Brazil, 2019

Most (93.3%; n = 56) sinks had refillable soap dispensers made of easy-to-clean material (100%; n = 60). From these, 85% (n = 51) were already working at the moment of the visit22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
. Regarding alcohol dispensers, all were easy to clean and refillable.

Still with regard to supplies for hand hygiene, it was found that, in 98.3% (n = 59) of health care units, paper towel dispensers were also at the sinks, were easy to clean and did not show signs of oxidation. Furthermore, the paper towels were adequately stored within the dispensers (98.3%; n = 59) and had good drying capabilities, enabling individual use, sheet by sheet (96.7%; n = 58), not leaving any particles (91.7%; n = 55)22 Mello MS.

. The aprons used to care for the patient in contact precaution were mostly (56.6%; n = 35) made of fabric in both units; were disposable in 35.9% (n = 21) of them; and in 7;5% (n = 5), there both fabric and disposable aprons.

Considering the physical distribution of the beds, in 90% of sectors (n = 54), the distance between the was at least 1 meter. This result corresponded to 93.3% (n = 28) of the ICUs and 86.7% (n = 26) of the HUs. It was found that, in 48.3% (n = 29) of the assistance units, there were physical barriers between beds, most of these (90%; n = 27) being found in the ICUs22 Mello MS.

. The main physical barriers found in the ICUs were: walls (51.9%; n = 14), curtains (25.9%; n = 7), and individualized boxes (22.2%; n = 6).

DISCUSSION

The Ministry of Health11 Ministério da Saúde (BR). Agência Nacional de Vigilância Sanitária. Medidas de Prevenção de Infecção Relacionada à Assistência à Saúde [Internet].

has been requesting investigations of the difficulties showed by the professionals who plan assistance in adhering to the actions to contain bacterial resistance, requiring assessments through the situational diagnosis of the gaps that can impact in the adherence to the directives of prevention of bacterial resistance in clinical practice. From this perspective, the verification of knowledge is essential, especially when supported by institutional policies and directives of patient safety. The knowledge about preventive measures, after all, aids in molding a culture of institutional safety, standardizing care using better practices, producing a safer environment, minimizing risks, and mitigating adverse effects1616 Drekonja DM, Grigoryan L, Lichtenberger P, Graber CJ, Patel PK, Van JN, et al. Teamwork and safety climate affect antimicrobial stewardship for asymptomatic bacteriuria.

https://doi.org/10.1017/ice.2019.176...
.

This study showed that the nursing coordinators of the HUs and ICUs had insufficient knowledge about measures to contain bacterial infections, specifically with regard to standard plus contact precautions, knowledge of the five moments of hand hygiene, and identification of the fundamental principle around which RDC 42/20101515 Ministério da Saúde (BR).

revolves.

Researches that evaluated the knowledge of health professionals with regard to bacterial resistance corroborate the findings of this study, in which this knowledge has been found to be restricted and limited1717 Baloh J, Thom KA, Perencevich E, Rock C, Robinson G, Ward M, et al.

https://doi.org/10.1590/0034-7167-2016-0...
. Still in accordance with the results found, a research carried out in a Brazilian hospital found that only 8.1% of professionals correctly described the five moments of hand hygiene1818 Oliveira AC, Pinto SA. Participação do paciente na higienização das mãos entre profissionais de saúde. Rev Bras Enferm. 2018;71(2):259-64. https://doi.org/10.1590/0034-7167-2016-0124

.

When professionals are unaware of elements that involve forms in which resistant bacteria can be transmitted and how to prevent this transmission, they tend to underestimate the risk and not to adopt precautions in clinical practice22 Mello MS.

. As a result, it is essential to continuously carry out institutional training sessions, since they lead to improvements in the knowledge of the multiprofessional team about health care processes and activities. The training sessions must promote the development of new abilities in care, integrating new professional categories22 Mello MS.

Literature about the theme is unanimous in stating that the path towards controlling the dissemination of bacterial resistance goes through the knowledge and behavior of health professionals when confronted with recommendations of good practices22 Mello MS.

The knowledge of health professionals about the mechanisms for the transmission of resistant bacteria and strategies to prevent it raise their awareness about the importance of their individual and collective practices, and about how they relate to the problem22 Mello MS.

.

This means that the more the professionals understand bacterial resistance and its impacts, the greater will their perception of risk be, and, as a result, the more likely they will be to adhere to preventive measures. This is especially true for those related to standard precautions, since these are the first barrier for controlling the dissemination of resistant microorganisms22 Mello MS.

Still from the perspective of knowledge, studies point at the theoretical-practical insufficiency in the formation of the professionals who are working in patient care as one of the factors that contribute for the difficulties in the consolidation of measures to control bacteria resistance and prevent against it22 Mello MS.

They also emphasize that it is necessary to rethink the teaching of this theme in graduation courses, in all fields of health formation, for changes in culture and behavior to actually take place in clinical practice22 Mello MS.

In this study, the low adherence to hand hygiene, the insufficient adherence to standard plus contact precautions, the absence of criteria for antibiotic prescription, the lack of supply, the sizing of personnel, the cleanliness of the environment, the flaws in the delivery of the results of cultures, and the indication of unnecessary invasive procedures were mentioned as the main difficulties to contain bacteria resistance in hospitals from Minas Gerais.

The use of standard plus contact precautions, associated to the cleaning of the environment, have been pointed out as multifaceted strategies to reduce the dissemination of resistant microorganisms in ICUs. To this end, the need to develop practices to encourage adhering to these practices in health institutions is reiterated22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

https://doi.org/10.3904/kjim.2016.323...
.

Regarding the sizing of the personnel, it is a challenge that needs to be met to contain bacterial resistance, especially considering the evidence that suggests that the small number of professionals of health care assistance, considering the large number of patients that require assistance, has a direct impact in the adherence to good practices to prevent and control infections22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

https://doi.org/10.4025/cienccuidsaude.v...
.

The work overload, due to undersized personnel, and the excess of patients that each member of the team needs to care for, are indicated in literature as factors that difficult the performance of care and the adherence to measures to prevent infections and disseminate resistant microorganisms22 Mello MS.

Concerning infrastructure, studies have reiterated the importance of alcohol dispensers in the points of assistance, as recommended by the RDC 42/2010. They also indicated how important are signs to remind the worker about hand hygiene, and the availability of quality personal protection equipment in sufficient numbers, to favor the adherence to hand hygiene and standard plus contact precautions22 Mello MS.

. An improvement was found in the adherence to hand hygiene after alcohol dispensers were installed, coupled with reminders in the places of assistance. The same was true after the implementation of training and feedbacks2020 Saharman YR, Aoulad FD, El-Atmani S, Sedono R, Aditianingsih D, Karuniawati A, et al.

.

Regarding the availability of supplies for hand hygiene in the places that provide assistance, the findings of this research differ from those from other studies2525 Prado MF, Hartmann TPS, Teixeira FLA. Acessibilidade da estrutura física hospitalar para a prática da higienização das mãos. Esc Anna Nery [Internet]. 2013 [cited 2019 Sep 23];17(2):220-6.

, since, in most hospitals, the soap, alcohol, and paper towel dispensers were in working conditions, filled, and required no hand contact.

However, the distribution of these dispensers should be considered, since in more than 50% of the nursing stations the soap and alcohol dispensers were next to each other on the sinks. This placement can implicitly reinforce the idea that these procedures should be carried out sequentially, which the team should avoid22 Mello MS.

. This can explain what was found during observation, that the cleaning of the hands was often complemented with rubbing alcohol immediately after. The main directives from the WHO, the CDC, and ANVISA recommend against this procedure, since following the use of water and soap by that of alcohol contributes for the skin to become drier, in addition to wasting product33 Oliveira AC, Paula AO, Iquiapaza R, Gama CS.

The rubbing of alcohol has been proved as an effective antimicrobial action when the hands are not soiled, is easy to carry out, causes less damage to the skin and saves time, but in this study, the health professionals were not aware of the effectiveness of alcohol for hand rubbing. As a result, their preference for simple hand hygiene was justified by the fact that they did not believe alcohol could be used to this end, as opposed to the recommendations22 Mello MS.

, the most effective way to guarantee good hand hygiene is using alcoholic preparations, as long as the hands are not visibly soiled. This finding is justified because using alcoholic preparations for the hands has the following advantage: most microorganisms are eliminated; the product is available in the health care station; the skin tolerates it well; no special infrastructure is necessary (such as clean water, sink, soap, and towel); and, when compared to washing hands with soap and water, it takes much less time (20 to 30 seconds)88 Centres for Disease Control and Prevention.

This research showed, clearly, how health professionals failed in their knowledge with regard to the moments of hand hygiene, as well as their lack of knowledge about the effectiveness of products and types of hand hygiene.

Furthermore, this study also calls attention to the fact that the professionals used powdered gloves. This finding is a barrier for the alcoholic rubbing of hands, since the powder, as it gets in touch with the alcoholic preparation, forms an undesirable residue in the hands, requiring the professional to use water and soap22 Mello MS.

. Considering this limitation, and risks such as hypersensitivity and severe air passage inflammation, the Food and Drug Administration (FDA), in 2016, prohibited the use of powdered gloves in surgeries and clinical practice2727 Food and Drug Administration. Banned devices; powdered surgeon's gloves, powdered patient examination gloves, and absorbable powder for lubricating a surgeon's glove [Internet]. 2016 [cited 2019 Sep 23].

https://www.federalregister.gov/document...
.

However, in Brazil, at the moment of publication, health laws do not prohibit the commercialization and use of powdered gloves in health care22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
. Both types of glove can be found for sale, and each institution is responsible for choosing which they prefer. However, the data obtained indicates that it is still necessary to invest in researchers that show the consequences of the use of each one, to provide the workers with more safety and comfort. This is relevant because, according to a study carried out in Brazil among nursing workers, institutions that are more worried about the quality of health of their workers lead to better quality in health care work2828 Carvalho DC, Rocha JC, Gimenes MCA, Santos EC, Valim MD.

.

Regarding the use of fabric aprons, which are predominantly used by the professionals in the health care units of the participating hospitals, studies state that these items must be capable of preventing the dissemination of microorganisms. This means that, if they are made of fabric, they must undergo safe reprocessing mechanisms, and the maximum frequency with which these articles can be reused must be evaluated constantly, since reusing them can compromise their efficiency as a barrier to contamination22 Mello MS.

https://www.cdc.gov/niosh/docket/archive...
, highlights the effect of contact precautions. This guideline reiterates the importance of physically separating patients who have been colonized/infected by resistant strains from those who have not, preferably in private rooms. However, the reality of health care around the world often does not allow for such separation, making it necessary to carry out cohorts, that is, to use a strategy that separates, within the same environment, patients with similarly resistant bacteria22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
. Cohorts are accepted strategies especially in regard to endemic resistant microorganisms in institutions, working as methods to encourage the professionals to adhere to the precautions and to the measures to control the dissemination of these pathogens in the health care environment88 Centres for Disease Control and Prevention. Guideline for isolation precautions: preventing transmission of infectious agents in healthcare settings [Internet]. 2007 [cited 2019 May 17].

, which was found in most assistance units, must be respected.

The absence of an adequate infrastructure, concerning distance and the existence of physical barriers between beds, the availability of personal protection equipment, and that of supplies and quality materials for hand hygiene, are still flaws in the adherence of measures to prevent and control bacterial resistance22 Mello MS.

Study limitations

Although the observational model is seen as an important strategy in the analysis of processes and routines, the “Hawthorn Effect” may have taken place. There was an attempt not to let the professionals accompanied know that they were being observed, and all of their actions were observed as they happened, to decrease the chance they noticed they were being observed; however, the fact that they knew about the presence of the researchers may have increased their adherence to some practices. To minimize this effect, the observations were carried out in the same moment as the situational diagnosis22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15]. Available from: https://repositorio.ufmg.br/handle/1843/31014
https://repositorio.ufmg.br/handle/1843/...
.

Furthermore, although this is a representative sample, the interviews and the observations of health care units were carried having the hospital unit as a reference, and not the number of professionals in each hospital who participated in the study. However, the results found were compatible and can be generalized, since the sample considered, of large hospitals from Minas Gerais, included more than 90% of these institutions22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

.

Contributions to the field

Studies indicate that improving the adherence to practices to control bacteria resistance requires the availability of financial resources, policies targeted at the subject, efforts and investments in training the professionals, the provision and supply of equipment, input, and physical structures that are adequate for the processes of a safe health care of quality22 Mello MS. Ações para prevenção e controle da resistência bacteriana em hospitais de grande porte de Minas Gerais[Dissertação] [Internet]. 2019 [cited 2019 May 15].

.

The support and partnership from the administration of the cities, States, and from the government is paramount to develop public actions and policies, based on the concrete reality of the institutions. Furthermore, for these policies to be effective, it is also important to carry out investigations to evaluate the knowledge about good practices to prevent and control the spread of resistant bacteria, and the difficulties that involve the adherence to these measures. This is the only way in which actions can be targeted at the gaps found, favoring their effective adoption in clinical practice.

CONCLUSIONS

This study uncovered the factors that make the control of bacterial resistance more difficult in large hospitals in Minas Gerais, such as the shortcomings in the knowledge of the professionals about preventive measures, and flaws related to the infrastructure, such as soap dispensers being positioned side-by-side in health care stations, and the absence of physical barriers between beds in health care units. Furthermore, weaknesses connected to personal protection equipment (powdered gloves and fabric aprons) were also observed.

In spite of that, this study also found factors that favor the control of bacteria resistance in the institutions: the availability of materials such as water, sink, and dispensers of soap, alcohol, and paper towels for hand hygiene. As a result, the lack of infrastructure and of supplies, that many mentioned as the cause for the non-adherence to hand hygiene, would not be a justification for non-adherence in the case of the institutions assessed here. This reiterates how important it is to adopt measures that increase knowledge and to monitor actions targeted at controlling bacterial resistance in the clinical practice.
