Introduction
Finding the appropriate current evidence that a busy general practitioner needs for decision-making during consultation implies developing resources that filter expanding literature according to reliability and relevance, and presenting it in an easily and quickly accessible way. 1 A variety of resources are available to physicians, including clinical practice guidelines, medical compendia and computerised decision-support systems. 2
Efforts have been made to develop high-quality guidelines internationally, yet their methodological rigor and editorial independence often remain poor 3 and they are rapidly outdated. 4 Even if they are trustworthy, they can be complex 5 or difficult to apply, 3 and their format makes them difficult to consult at the point of care.6,7 In France, their utility is well recognised, but their dissemination and implementation in practice have been neglected.8,9
Clinical decision support systems are increasingly considered the best tools for guidelines implementation, as they provide the appropriate recommendations according to the patient’s clinical situation. 2 However, their effectiveness to improve patient care is still disappointing and they can contribute to alert fatigue and to physician burnout due to electronic health records. 10
Point-of-care, web-based medical compendia are resources specifically designed to deliver rapidly accessible, pre-digested, comprehensive, periodically updated, evidence-based information to clinicians,
11
which could facilitate the use of guidelines.
12
More than 20 systems have been developed worldwide, like BMJ Best Practice in the UK, or Dynamed and UpToDate in the USA, which have been assessed as being in the top three according to their information volume, editorial quality and evidence-based methodology.
11
EBM Guidelines is one of these medical compendia, produced for primary care by the Finnish medical company Duodecim. It is a collection of 1000 guidelines linked to 4000 evidence summaries in Finnish and English, mainly based on the Cochrane reviews.
13
The process used to develop these guidelines has been accredited by the National Institute for Health and Care Excellence (NICE) in the UK, based on the AGREE criteria.

Evaluating health information systems is required to insure their effectiveness and safety, 18 as they should have an impact on clinical practice and patient health. 19 Since health care practice is highly context-sensitive, however, their evaluation should be performed in their context of use in order to be meaningful. 20 According to two studies, EBM Guidelines scored in the top quartile for evidence-based methodology and above the median for volume coverage.21,11 Their use in context had once been assessed in Finland. 22
As no such no such point-of-care, web-based medical compendium was available in France, we conducted an experimentation of the Belgian EBMPracticenet website, in the context of French general practice. The aim of this study was to assess physicians’ participation, search effectiveness and users’ global appraisal of
Methods
This study consisted in a global evaluation of the website’s content and interface, in its context of use in routine French general practice, through indicators based on physicians’ procedures and appraisal.
Physicians’ recruitment
From January to February 2017, we recruited 367 members of the French National College of General practice via its mailing list (including approximately 2000 general practitioners (GPs)), and 50 postgraduate trainees from the French medical schools of Lyon and Saint-Etienne during university meetings. Those 417 registered physicians received an email with detailed website login instructions and were encouraged to use it at the point of care from March to September 2017. They also received monthly email reminders to use the
Data collection
At their first connection, the participating physicians were asked to complete profile data. A personal login identification password was assigned to each in order to analyse their frequency of use and search behaviour. Each search was recorded in the website logbook, which contained the following fields: user ID, timestamp(s), queries (words or phrases), title(s) of the guidelines opened. In their assessment of the EBM Guidelines in Finland, Jousimaa et al. 22 collected log files from users to measure the frequency of their searches.
During the 7-month study, search-specific, self-developed, assessment questionnaires were periodically activated online to assess physicians’ clinical search effectiveness (see Appendix 1). In addition, at the mid-point and end of the study, participants were asked by email and by post to complete a global assessment questionnaire, self-developed. This global assessment concerned website ergonomics (usability) and content (reliability, relevance to the French context, usefulness for practice), and physicians’ global satisfaction (see Appendix 2). The ergonomics perception was evaluated with the System Usability Scale (SUS), an international standard widely used for assessing information systems because it is valid, reliable even for small samples, and quick to administer and score. It consists of a ten-item questionnaire with five response options, and is based on a score ranging from 0 to 100. 23
Data analysis
From the logbook, we calculated the frequency of use per participant, as an objective indicator of participation. It was defined as the number of specific clicks performed monthly on the website, either for entering a query or for opening a guideline. From search specific assessments, we calculated the proportion of accurate answers provided by the website to searches. From the logbook, we distinguished inaccurate answers with no guideline opened from guideline(s) opened but no answer found by the physician. We calculated the mean SUS score and interpreted it according to the adjective rating scale designed by Bangor et al. 24
We compared the number of clicks of the physicians who responded, and those who did not, to the search-specific and global assessments, using the Student
Ethical and regulatory aspects
This study was declared to the French Data Protection Authority (CNIL, N° neS20672351). The participating physicians were fully informed of the aims of the study before consenting to participate.
Results
Among the 417 physicians registered, 262 (62.8%) performed at least one search on the website during the study period, including 229 GPs (89.8%) and 26 trainees (10.2%) (Figure 1; Table 1). Most GPs were trainers (63.3%). The physicians performed 10,737 clicks on the website, corresponding to 5234 queries entered and 5503 guidelines opened. On average, users clicked into the website 5.9 times per month (standard deviation: 9.7), corresponding to 2.9 queries entered, and 3.0 guidelines opened, per month. The respondents to the search-specific questionnaire clicked, on average, 13.0 times per month on the website, as compared with 2.4 clicks for the non-respondents (

Summary of physicians’ recruitment and participation to the study.

Evolution of monthly users and clicks per user* during the course of the study.
We collected 194 search-specific questionnaires from 85 physicians (32.4%). Most of them had performed their search out of the consultation (61.3%), found this process easy (94.2%) and fast (94.3%), and got an accurate answer (74.2%) (Table 2). We collected a global assessment from 158 physicians at the mid-point (60.3%), and from 103 physicians at the end of the study (39.3%). At mid-point, most responding physicians found the information provided by the website rather reliable (90.5%) and useful for practice (75.3%), were rather satisfied (55.7%), and wished to continue using the website (94.9%). At the end of the study, most responding physicians also found the information provided by the website rather reliable (92.2%) and useful for practice (78.6%), were rather satisfied (63.1%), and wished to continue using the website (95.1%). No change was observed for these variables between the mid-point and the end of the study (Table 3). The mean SUS score was of 73.9 at the mid-point, and 70.3 at the end of the study, with no change in the meanwhile (
Search-specific assessment (
Global assessment.
We obtained 56 comments from the search-specific assessment, and 127 from the global assessment. Respondents mainly reported problems concerning the use of the website during the consultation, connection to the website, query terms entry, relevance of guidelines retrieved, comprehensiveness of the answer and its consistency with French recommendations (Table 4). The main barriers to using the website during consultations were search slowness and guideline length.
Main comments.
Of the 1038 guidelines accessible on the website during the study, 803 different guidelines were opened at least once (77.4%) and 636 at least twice (61.3%). The 20 most consulted guidelines accounted for 14.8% of guidelines opened. The five most consulted guidelines were on Lyme borreliosis, dermatophytosis, vulvovaginitis, gout and osteoporosis (Table 5).

During our 7 months of experimentation of the
Confrontation to literature
The under-weekly frequency of both queries entered and guidelines opened was low compared with the number of clinical questions usually raised by primary care physicians. It has been estimated that physicians usually raise between 7 and 185 clinical questions per 100 consultations, of which, half lead to a search.25,26 In fact, it would be worth comparing the low frequency of use of the website with the usual rate of guideline consultation by physicians, which is unknown. In our study, the number of participants decreased more than the frequency of use by the persistent physicians. Overall, we observed two groups of physicians: a majority who stopped participating and a minority who persisted until the end of the study.
The low frequency of use of the website can be explained by both the lack of effectiveness and usability of the website, but also by the user behaviour and the context of use of the website. According to the mean SUS score, the website ergonomics was perceived as good, but not enough to recommend it to a colleague.23,27 The main barriers to using the website were the effort and time required to find accurate information, especially during the consultation. This is consistent with the literature, which identified time issues as the main barrier to the seeking of information by physicians.1,25,28,29 The participating physicians also reported difficulties selecting appropriate search terms and retrieving relevant guidelines. Physicians are increasingly aware of the various sources of medical information, but not specifically trained to search within medical databases.28,30 In addition, guidelines indexation was probably incomplete and sometimes inappropriate in this version of
Some 74% of searches performed on the website led to an accurate answer. This is consistent with data from a systematic review, indicating that various medical information sources answered 78% of physicians clinical searches 26 ; in an evaluation of the use of EBM Guidelines in Finland, 71% of physicians found complete answers. 22 If the efforts to search the website may have discouraged some physicians, those who persisted and responded to our questionnaires found answers to most of their clinical questions.
The large variety of guidelines consulted shows the scope and the diversity of information needs in general practice. Most of the top 20 consulted guidelines were for relatively common acute or chronic health problems (urinary tract infections, arterial hypertension, hypothyroidism); among them, 6 belonged to the 20 most frequent health problems managed by French physicians. 32 This list also included rare conditions (hemochromatosis, swelling of the salivary glands, hypercalcemia and hyperparathyroidism) or publicised health problems (borreliosis of Lyme, cow’s milk allergy, dyslipidaemia).
Perspectives
In Finland in 1998, physicians consulted the EBM Guidelines – on CD-ROM at this time – on average three times per day.
22
To implement
Navigation in the website should be facilitated and guidelines indexation enhanced in order to retrieve accurate information in a minimum of time. Guidelines in the website are currently indexed with the International Classification of Primary Care (ICPC-2), the International Classification of Diseases (ICD-10) and the Medical Subject Headings (MeSH).
17
The Belgian Biclassified Bilingual Thesaurus (3BT) is also integrated into the website to help search guidelines more quickly and effectively.
33
This thesaurus could be improved based on the analysis of the website query logs, which include terms commonly used by French physicians. To fit the website to the French context, the Finnish translated guidelines should be adapted to improve their applicability and their appropriation by physicians. Among several processes developed worldwide for that purpose,

as used for the Belgian
French physicians are increasingly trained in evidence-based medicine. Specific training for postgraduate students in medical database searching may improve their skills and the frequency of use of the website. 36 In Finland and Belgium, access to the EBM Guidelines database is free for physician users. The economic model for France should be well thought-out, as the imposition of access fees to the website could impede its use by physicians. 37
Strengths and limitations
Among the three best evaluated point-of-care information systems (UpToDate, BMJ Best Practice and Dynamed), only UpToDate has been evaluated in context.31,38 However, the setting of use differed from general practice in both studies and none of them included both a search-specific and a global assessment.
We cannot exclude a selection bias, as the physicians who evaluated the website via the search-specific and the global assessment questionnaires were those who used it most, and were presumably the most satisfied with it. However, it can be assumed that their better awareness of the website made their assessment more relevant. The generalisability of our findings can also be questioned, as most participating GPs were GP trainers. Although they are more interested in evidence-based medicine and have more information needs, they face the same difficulties in seeking and using evidence-based information1,39 and do not consult guidelines more frequently than non-trainer GPs. 40 In addition, GP trainers can be considered as globally representative of all GPs. 41
Unlike a one-year Finnish evaluation, which involved experienced users of the guidelines, 22 this study involved French physicians who were new users. In this context where a too long study period could have led to physicians’ demobilisation, a 7-month length seemed a good compromise between the acceptability to the participants and the volume of data collected. The stability of results of the global assessment between the mid-point and the end of the study supports their reliability and sustainability, at least for physicians who responded to the final assessment.
Apart from the SUS score, the questions in the global assessment questionnaire and in the search-specific questionnaire were self-developed. This strategy resulted from the absence of a validated tool for evaluating the content of, and users’ satisfaction with, point-of-care information systems in their context of use. 42 The questionnaires used were not assessed for validity or reliability.
Conclusion
French physicians who tested the Belgian
Since the present evaluation, a French website called ebmfrance.net, based on the EBM Guidelines collection translated into French, has been launched thanks to funding from the French Public health insurance system. Then two editorial processes have been undertaken, to integrate guidelines of the French National agency for healthcare quality (Haute Autorité de Santé) and adapt the EBM Guidelines to the French context.
