Antibiotic stewardship in French nursing homes: a 2019 regional survey.

BACKGROUND: Antibiotic resistance is a growing issue in nursing homes (NHs). Antibiotic stewardship (ABS) programmes can reduce antibiotic use in NHs, but few studies have assessed to what extent they are implemented in NHs.
OBJECTIVES: To describe ABS current practices and describe the opinion of NH stakeholders regarding ABS and opportunities for improvement in one French region.
METHODS: We invited by e-mail the medical and nurse coordinators of all NHs of the Grand Est region, France, to participate in our survey in 2019. The online questionnaire included 35 questions covering four topics: NH characteristics, current ABS practices, attitudes towards ABS and opinions on strategies to promote ABS. A score evaluating implementation of core ABS elements was calculated using the current ABS practice responses.
RESULTS: Out of 417 NHs, 75 (18%) participated in our survey. The three most implemented ABS activities were antibiotic consumption monitoring (65%), antibiotic plan documentation (56%) and antibiotic prescription guide distribution (54%). Audit and feedback, training sessions or identification of a local ABS leader ranged from 13% to 29%. Participants positively perceived ABS and most suggestions to improve ABS programmes in NH, with maximal interest in training, audit and feedback interventions. The median score for implementation of core ABS elements was 3.3 (IQR = 2.3-5.4; theoretical range 0-11), and the score distribution was not associated with any NH characteristic.
CONCLUSIONS: While there is still room for improvement, NHs had a positive attitude towards ABS strategies. Some regional and national initiatives to promote ABS in NHs exist and should be actively promoted.

Introduction

In Europe, in 2015, MDR bacterial infections were responsible for about 33 000 deaths and cost about 1.1 billion euros to the healthcare system of EU/European Economic Area countries. The two major drivers for antibiotic resistance are the use of antibiotics and poor infection and control practices. To tackle the global antibiotic resistance threat, antibiotic stewardship (ABS), which is defined as ‘a coherent set of actions designed to use antibiotics responsibly’ has been advocated since the late 1990s. Primarily studied in the hospital setting, it has been shown that MDR bacterial infections or colonization can be reduced by the implementation of ABS programmes.

Nursing homes (NHs), which are defined as facilities that provide 24/7 functional support for people who require assistance with activity of daily living and have identified health needs, also have antibiotic use and resistance issues., The 2016 European point prevalence survey of healthcare-associated infections and antimicrobial use showed that 4.9% of long-term care facility residents were receiving antibiotics on the day of the survey with large variations between countries (from 0.7% to 10.5%), including about one-third of prescriptions for prophylaxis. In the USA, the CDC reports that up to 70% of NH residents receive antibiotics each year and that 40%–75% of prescribed antibiotics are inappropriate or unnecessary. Moreover, living in a high antibiotic use NH (as compared with a low-use one) was associated with a 24% increased risk of experiencing any antibiotic-related adverse event (including Clostridioides difficile infections, infections with antibiotic-resistant bacteria or general adverse events). Several interventional studies or reviews on the effectiveness of ABS programmes in NHs have been published recently, and a meta-analysis of these studies concluded that ABS programmes in NHs can reduce antibiotic use by 14%. In the USA, the CDC has developed core elements of ABS programmes that are specifically adapted to the NH context.

Less than 10 questionnaire surveys have assessed to what extent ABS programmes are implemented in NHs., More than half of them were conducted in the USA, where ABS programmes have been mandatory in NHs since 2016, with only one of these surveys having been performed in the last 4 years. In Europe, two surveys exploring beliefs towards antimicrobial resistance and stewardship were conducted in Ireland and Belgium, with the 2016 ECDC HALT point-prevalence survey providing some information on ABS activities in 1788 NHs in 26 European countries.,, No data are available for France on this topic to the best of our knowledge.

Our objective was to describe current ABS practices as well as opportunities for improvement in nursing homes in one French region, using a questionnaire survey.

Methods

NH context in France

In France, NH residents are usually aged 65 years or older and may stay temporarily, but more frequently permanently, in the NHs. They need constant supervision and nursing care, but they are medically stable and do not need invasive medical procedures or constant medical care. Residents are free to choose their own GP, who is not an employee of the NH present on site and is frequently the same GP they had while living in the community. Some NHs are hospital-based NHs (18.8% in France, National Health Insurance data) and thus benefit from the hospital services such as on-site pharmacy, laboratory or imaging; in that case, their ABS activities are those of the hospital they are related to. However, most French NHs are community-based NHs and do not usually have on-site pharmacy or biology/imaging services. In these NHs, residents can also choose their community pharmacy, biology or radiology provider but some NHs have a partnership with a specific community pharmacy or biology laboratory. On-site NH employees include nurses and nurse assistants, and usually one medical coordinator and one nurse coordinator in charge of the organization of residents’ healthcare. Regarding antibiotic resistance, in the Grand Est region, in 2019, ESBL-producing Enterobacteriaceae represented respectively 7.7% and 12.5% of Escherichia coli and Klebsiella pneumoniae clinical samples from NH residents, and 45.3% of Staphylococcus aureus isolates were MRSA (further details on antibiotic use and resistance are available in Appendix S1, available as Supplementary data at JAC-AMR Online).

French NHs do not have any mandatory requirement to implement ABS programmes. There are however regional or national initiatives promoting ABS in NHs in France (Appendix S2).

Survey questionnaire

We first performed a literature review of published surveys about ABS programmes in NHs,, as well as core elements of NH ABS programmes., The draft questionnaire was then reviewed by the scientific committee composed of infectious diseases specialists, public health specialists, GPs (taking care of NH residents) and representatives of several regional health authorities or organization’s that all officially supported the survey (Agence régionale de santé Grand Est; AntibioEst (the regional ABS network, in place since 2003); Direction régionale du service médical Grand Est; Observatoire des médicaments, dispositifs médicaux et innovations thérapeutiques Grand Est). The questionnaire was validated during a scientific committee meeting and pilot-tested with 10 NH medical coordinators.

The final questionnaire (Appendix S3) included 35 questions covering four main topics: NH characteristics, current ABS practices (including core elements of NH ABS programmes), attitudes towards ABS and suggestions for improvement. Most questions were close-ended questions and some of them were evaluated using a 5-point Likert scale, ranging from 0 (no interest/impact) to 5 (maximal interest/impact).

Surveyed NHs

We targeted all community-based NHs in the Grand Est region in northeastern France (5 555 186 inhabitants in 2016). NHs with an on-site pharmacy were excluded from our survey since they were most likely to be hospital-based and benefit from existing ABS programmes present in the hospital.

Survey administration

AntibioEst sent an e-mail to all eligible NHs, including an invitation letter (mentioning all organizations supporting the survey), a weblink to the online survey (available on SurveyMonkey®) and a PDF version of the questionnaire. When possible, a joint reply by both the medical and nurse coordinators was recommended. Each NH could either reply to the survey online or send the completed PDF by e-mail or postal mail.

The survey opened on 4 June 2019 and was closed on 30 November 2019. Up to three reminders were sent to NHs. Non-responding NHs were also contacted by phone after the second reminder. They were asked if they had received the e-mail invitation and encouraged to participate in the survey; their contact details were also double checked. No incentives were provided, except feedback on the results of the survey.

Data analysis

Firstly, we performed a descriptive analysis of the results using Excel®. Categorical variables are presented as numbers and percentages and continuous variables as medians and IQR. Based on responses from the current ABS practices section, we designed an 11-point score to reflect the ABS core elements’ implementation level of each NH (see Appendix S4 for details). NHs were then categorized in four groups according to their 11-point ABS score, corresponding to the four quartiles of the score distribution, and we tested the association between NHs’ characteristics and the ABS group, using Fisher’s Exact test for categorical variables and ANOVA for continuous variables. This analysis was performed on SAS® version 9.4 (SAS Institute Inc., Cary, NC, USA).

Ethics statement

This study did not modify the medical care of residents, and complete anonymity was respected during the analyses. An ethics committee’s approval was therefore not required, according to French law.

Results

Characteristics of participating nursing homes (Table 1)

Out of 417 community-based NHs, 75 (18%) participated in our survey. The medical coordinator replied on his/her own in more than half of the cases (53%, 38/71), with 23% (16/71) of joint replies by both medical and nurse coordinators.

Almost all responding NH had a nurse coordinator (97%, 70/72) and/or a medical coordinator (88%, 63/72). The median number of GPs who took care of at least one resident in each NH was 15 (IQR: 8.5–22.5). The median (IQR) number of full-time equivalents working in NHs was 0.4 (0.3–0.5) for the medical coordinator, 4 (3.5–5) for nurses and 18 (14–21) for nurse assistants; the median number of residents was 72 (60–81) per NH. Forty percent (29/72) of NHs were part of a larger group of NHs, and most of them had a partnership with a community pharmacy (83%, 60/72) or a biology laboratory (82%, 59/72). All but one NH had computerized medical records and 73% (52/71) had computerized antibiotic prescribing.

Current ABS practices

Core elements of ABS programmes were overall present in less than half of participating NHs (Table 2). Among the listed ABS activities, 3% (2/72) of surveyed NHs did not have any in place.

NHs having access to their antibiotic consumption data (at least annually)	47/72	65
NHs having access to their bacteriological data (at least annually)	26/72	36

Twenty-two percent (16/72) had designated a professional responsible for coordinating infection/antibiotic management activities in the NH. His/her roles were to help manage infection treatment (12/16), to promote ABS (10/16), to help with infection diagnosis (8/16) and/or to monitor antibiotic resistance (4/16). Half of these professionals were the medical coordinator of the NH, with a nurse being responsible in some cases (4/16).

More than half (54%, 38/71) of the responding NHs provided a therapeutic guide for antibiotic prescribing in common infections (e.g. urinary, respiratory or skin infections) but protocols dealing with the diagnosis and microbiological tests were overall less frequently available [ranging from 10% (6/61) for therapeutic management for blood cultures to 68% (47/69) for urine cultures sampling]. Twenty-three percent (16/71) of NHs informed prescribers about ANTIBIOTEL, a free regional phone line offering advice from infectious diseases specialists. Recording indication, dosing and duration when prescribing antibiotics was requested in more than half of the NHs. There was no systematic reassessment of treatment at 48–72 h nor at 7 days in 59% of them (42/71).

Training sessions about infection management and/or antibiotic prescribing had been offered in the past 3 years for medical staff and nursing staff in respectively 23% (16/70) and 29% (20/70) of the responding NHs, but only a few (9/70, 13%) performed an internal audit and feedback to evaluate practices on antibiotic use and/or infection management. About two-thirds (47/72) of NHs had access to their antibiotic consumption data (at least annually) but only one-third (26/72) had access to bacteriological data. Some respondents reported other ongoing initiatives, such as ABS discussions at the regional geriatric committee and facilitating communication between physicians and the nursing staff.

Attitudes toward ABS and suggestions for improvement (Table 3)

Overall, most items were perceived as useful by the participants. Medical and nursing staff (including coordinators) were considered as being the most relevant persons to influence antibiotic prescriptions. Administrative directors, residents or their relatives were viewed as having little influence on antibiotic prescriptions.

The interventions that were perceived as being the most useful were training sessions for physicians, the distribution of antibiotic prescription guides and documenting an antibiotic plan.

ABS implementation score

The median score of ABS implementation was 3.3 (IQR = 2.3–5.4) (11 representing the maximum number of ABS core elements implemented). Quartiles of ABS implementation score were as follows: Q1 = 0–2.3, Q2 = 2.3–3.3, Q3 = 3.3–5.4, Q4 = 5.4–7.7.

No significant association was found between NH characteristics and the four quartiles of ABS implementation score (Table 4).

Discussion

This survey shows that ABS programmes are insufficiently implemented in French NHs, even though the medical and nurse coordinators who participated in this survey seemed aware this is a public health priority. Most suggestions were favourably perceived when asking about ABS opportunities. No specific NH characteristic associated with the level of implementation of ABS activities at NH level could be identified.

Overall, only 2/72 (3%) surveyed NHs did not have any ABS activity in place. In a recent Belgian survey, only 23% of the 39 participating facilities had an ABS programme in place. Table 5 compares our results with the literature, with most of the studies listed in this table conducted in the USA, as ABS programmes are mandatory in NH in that country. However, the European context can be different, even among countries, as described in a recent article conducted in the Netherlands, Norway, Poland and Sweden. The ABS core elements most often implemented in both our region and the literature were monitoring of antibiotic consumption, availability of guidelines for antibiotic prescribing, documentation of the antibiotic plan and reassessment of antibiotic prescriptions. These strategies also obtained the highest scores in our evaluation of perceptions of ABS interventions, probably because they are relatively easy to implement and are not very time or money consuming. Conversely, available expertise on infection management and training strategies were poorly implemented in our region as compared with previously published surveys. This is quite surprising, as AntibioEst has been offering both services for free for years. Specific efforts must therefore be made to make NHs aware of existing national or regional initiatives and tools (Appendix S2). We did not assess management leadership and financial support, but these items had low implementation rate in NHs in the literature.

We did not find any significant association between the level of ABS core elements’ implementation and NH characteristics, possibly due to lack of power. A recent survey of six NHs in the USA suggested that facilities with training, feedback, benchmarking activities and the presence of a local leader for infection prevention and control had lower rates of antibiotic consumption. This was confirmed by Fu et al. who found that in 861 NHs in the USA the presence of a certified infection prevention and control leader, being part of a for-profit group of NHs or participating in a health quality programme were associated with more comprehensive ABS programmes. In our survey, only 22% of responding NHs had an identified professional in charge of infection/antibiotic management as compared with 59.4% of NHs having an on-site care worker in charge of infection prevention and control in the 2016 French national survey. Many reviews about ABS in NHs have emphasized the importance of having a local leader within the facility to lead the change from within.,,

This study brings original findings, but it has some limitations. The response rate was quite low (18%), despite several reminders, as in several other published NHs surveys. Therefore, we cannot exclude a selection bias, as it is likely that the responding NHs were more aware of the antibiotic resistance issue, meaning that our results might present an optimistic perspective on the true ABS situation in our region. A social desirability bias is also possible, but most replies reported a suboptimal situation, which makes this bias quite unlikely. We also could not collect information about non-responding NHs’ characteristics, to assess if respondents were representative of all NHs in our region. However, when comparing the full-time equivalents for medical and nurse coordinators with a 2015 national survey, similar results were found. Finally, although we asked both medical and nurse coordinators to reply jointly to the questionnaire, this was the case in less than a quarter of cases, which may limit the validity of some replies.

In conclusion, French NHs have started to implement strategies to improve antibiotic use, with NHs’ stakeholders having a favourable attitude towards ABS, but there is still large room for improvement. Defining ABS core elements for NHs at national level in France would certainly be helpful. Regional health authorities, with the support of regional ABS networks, could then take a leading role in implementing these elements. The inventory of practical tools we published recently might be a starting point to stimulate sharing of best practices.
