During the preoperative outpatient visit to the OTS department, patients were informed in detail about the study, and they were offered the possibility of participating, regardless of whether they had access to the internet or not. Information was verbally communicated, always by the same person (co-author of the study), and patients were given a detailed information sheet about the study, for which their informed consent was obtained.</p><p id="par0045" class="elsevierStylePara elsevierViewall">Those patients who refused to take part in the study were asked to provide details of their reasons, without this being detrimental or harmful in any way to their treatment or clinical follow-up of their condition.</p><p id="par0050" class="elsevierStylePara elsevierViewall">A website was contracted for the survey.

This definition is based on the premise that the HRQOL are only useful when all items are completed. In addition, the patients classified as “incapable” were divided into 3 subcategories: (1) those patients who since the beginning had decided not to participate in the study; (2) those who after accepting, had not accessed the website; and (3) those who accessed the website but did not complete the questionnaires.</p><p id="par0075" class="elsevierStylePara elsevierViewall">Once the study came to an end we contacted the “incapable” patients who had initially consented to participate (corresponding to categories 2 and 3), to find out the reason why they had not been able to complete the questionnaires.</p><p id="par0080" class="elsevierStylePara elsevierViewall">All data were collected anonymously and treated confidentially using the telematic platform.

Of these, 14 refused to participate, indicating as their main reason the impossibility of accessing the Internet, whilst 84 patients (85.7%) did accept. Out of these, 42 patients (50%) finally indicated that they would participate but then later did not access the website, 6 gained access to the website but did not know how to respond or only partially responded to the surveys and the remaining 36 patients responded completely to the questionnaires (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Consequently, only 37% of the participants were considered capable of satisfactorily responding telematically to the survey, as opposed to the 80% assumed in our initial hypothesis.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><p id="par0105" class="elsevierStylePara elsevierViewall">The mean age of the 36 capable patients was 71.1 (8.3), compared with 73.7 (±) of the incapable ones; this difference was not statistically significant (<span class="elsevierStyleItalic">P</span><span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>0.085).

Of the remainder who did agree to participate in the study, 42 (43%) did not access the Internet and the response of 6 (9.6%) was incomplete. Of the 42 patients who had accepted to participate in the study but did not access the Internet, 19 (30.6%) reported they had difficulties in doing so, 9 (14.5%) forgot to do the survey despite having access to the Internet, 2 did not know how to get onto the website, one changed their mind and decided not to participate and one stated that the website did not work. It was not possible to contact another 10 patients to find out the reason why they had not participated in the survey.</p><p id="par0115" class="elsevierStylePara elsevierViewall">The 36 who were capable of satisfactorily completing the questionnaires, responded to the additional evaluation survey on the difficulty of access to the website and its content, and whether they required help in completing it. Of these, 28 (77.8%) indicated that responding telematically to the survey presented no major difficulty for them (15 responded normal, 5 easy and 8 very easy). A great majority (30) indicated they had received help from a family member. With regard to survey content, only one patient stated that they had found it very difficult. Finally, 27 (75%) completed the survey at a single attempt (<a class="elsevierStyleCrossRef" href="#tbl0010">Table 2</a>).</p><elsevierMultimedia ident="tbl0010"></elsevierMultimedia></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0080">Discussion</span><p id="par0120" class="elsevierStylePara elsevierViewall">Of the patients who underwent TKR in our hospital, a very much lower percentage than expected were capable of satisfactorily responding telematically to the quality of life questionnaires (36.7%), despite the fact that the majority of patients stated they had Internet access. For a variety of reasons, approximately one-quarter of the participants were incapable of completing the questionnaires despite having Internet access. In our study, although 61.5% reported they had access to the Internet, the majority required external aid to complete the questionnaires, and a cultural component therefore came into play which we had not evaluated regarding the availability or predisposition of family members and/or friends to help the survey participants.</p><p id="par0125" class="elsevierStylePara elsevierViewall">One possible explanation for the low rate of completion of the telematic survey in our study could be the advanced age of the patients (mean age of 72.7 years). According to the National Institute of Statistics,<a class="elsevierStyleCrossRef" href="#bib0170"><span class="elsevierStyleSup">16</span></a> in this age range, the percentage which accessed Internet in the last month was 12.9%, as opposed to 92.9% of the population aged between 16 and 24 or 82.8% of those aged between 25 and 34. This indicates a marked negative tendency to use the Internet as one gets older. It is possible that the outcome would have been different in other pathologies in younger patients.</p><p id="par0130" class="elsevierStylePara elsevierViewall">Despite the above, we were unable to observe any differences regarding age or gender which could explain the differences between the patients who were capable and incapable of satisfactorily completing the questionnaires. Other variables of potential interest such as educational or socio-economic level were not evaluated, since no information was available in this regard.</p><p id="par0135" class="elsevierStylePara elsevierViewall">With the appearance of new technologies and the extension of Internet usage, new systems have been established for self-completion of HRQOL questionnaires telematically.<a class="elsevierStyleCrossRefs" href="#bib0120"><span class="elsevierStyleSup">6,13</span></a> Collection of this valuable information is generally difficult and is inconvenient for professionals, especially because of the huge amount of time and resources required, and because they are not accustomed to it, many orthopaedic surgeons choose not to do so in the majority of cases.<a class="elsevierStyleCrossRefs" href="#bib0105"><span class="elsevierStyleSup">3,15</span></a> It was therefore assumed that using the Internet would improve completion.</p><p id="par0140" class="elsevierStylePara elsevierViewall">Notwithstanding, according to Keurentjes et al.,<a class="elsevierStyleCrossRef" href="#bib0175"><span class="elsevierStyleSup">17</span></a> there is a clear preference for patients who are to undergo knee and hip replacement operations to respond to questionnaires in paper format (86.8% and 81.8% respectively). However, we consider that for our specialty, although patients may have this preference, it would be feasible for them to be equally capable of responding to surveys telematically, especially bearing in mind increasing Internet usage.</p><p id="par0145" class="elsevierStylePara elsevierViewall">By using this technology, information is directly introduced by the patient, reducing the time they spend in the surgery and avoiding human transcription errors.</p><p id="par0150" class="elsevierStylePara elsevierViewall">It has been shown that patients familiarised with the use of these technologies respond to telematic questionnaires in less time than written or telephone ones. Help windows may be added to facilitate comprehension, providing additional information in response to possible doubts. Moreover, periodic reminders may be sent via email, SMS or similar means, to ensure their completion and alerts may be incorporated into the survey itself to detect when information is incomplete or the recorded responses are incorrect.<a class="elsevierStyleCrossRef" href="#bib0165"><span class="elsevierStyleSup">15</span></a></p><p id="par0155" class="elsevierStylePara elsevierViewall">Notwithstanding, prior to coming to a decision on the systematic recording of data using this method, we would have to explore the possible difficulties which may limit its viability, such as the barriers patients have in accessing new technologies, their inability to use them and the difficulties in correctly completing the questionnaires or the lack of assistance, particularly by family members with a higher level of competence in Internet usage.</p><p id="par0160" class="elsevierStylePara elsevierViewall">One must take into account that the percentage of homes with Internet access in Spain is lower than the other EU countries (67% compared with 76%).<a class="elsevierStyleCrossRef" href="#bib0160"><span class="elsevierStyleSup">14</span></a> Furthermore, predictably, older patients have greater difficulty using it and in completing questionnaires.</p><p id="par0165" class="elsevierStylePara elsevierViewall">There are studies which argue that the cost of carrying out this type of questionnaire is lower than paper-based ones,<a class="elsevierStyleCrossRef" href="#bib0180"><span class="elsevierStyleSup">18</span></a> although other studies support the fact that the cost of the questionnaires using this type of platform would depend on the sample size, larger samples being more profitable or beneficial.<a class="elsevierStyleCrossRef" href="#bib0165"><span class="elsevierStyleSup">15</span></a> In our case, there was no evaluation of this type at the start of the study and therefore no calculation could be made.</p><p id="par0170" class="elsevierStylePara elsevierViewall">It is probable that there will be a trend towards an increase in access to new technologies in Spanish homes, as has occurred up until now, thus increasing the capacity to respond to medical online surveys, when the population around us is more familiar with Internet usage and IT devices. The generations which currently use this type of technology will be our future study samples and probably fewer difficulties will be encountered for completing this type of survey.</p><p id="par0175" class="elsevierStylePara elsevierViewall">The application used for completing the questionnaires was the website <a href="http://www.surveymonkey.com/">www.surveymonkey.com</a>. Despite being a reliable and confidential site, probably the fact that it is external to the hospital leads patients to being somewhat reluctant to use it. Another telematic option to consider could be responding to surveys using a tablet which would collect the data in a computerised way. Easier and simpler-to-use tools or devices could possibly be designed which would help with completion of surveys but which at present we do not generally have at our disposition.</p><p id="par0180" class="elsevierStylePara elsevierViewall">It is also worth mentioning that since survey completion in this study was low, the secondary objective regarding the creation of a valid and reliable telematic platform for obtaining HRQOL questionnaire measurements could focus on participants with better Internet access and a willingness to complete. We could also therefore address the possibility of having a mixed survey, whereby the patient chooses whether to complete the survey online or on paper.</p><p id="par0185" class="elsevierStylePara elsevierViewall">Our study had several limitations; no relevant information was collected on patients’ social class or educational level, or the availability of assistance by a third party if required.</p><p id="par0190" class="elsevierStylePara elsevierViewall">It is also of note that the opinion surveys used put forward 4 very subjective categories and without any definition of the criteria for each one of them. However, roughly speaking, they express the perception of patient difficulty.</p><p id="par0195" class="elsevierStylePara elsevierViewall">To conclude, for the patients of our hospital scheduled for TKR surgery, Internet usage is not a viable strategy to ensure that quality of life data is obtained in a thorough and satisfactory manner.</p></span><span id="sec0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0085">Level of evidence</span><p id="par0200" class="elsevierStylePara elsevierViewall">Evidence level V.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0090">Ethical responsibilities</span><span id="sec0040" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">Protection of human beings and animals</span><p id="par0205" class="elsevierStylePara elsevierViewall">The authors declare that no experiments were performed on humans or animals for this investigation.</p></span><span id="sec0045" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0100">Data confidentiality</span><p id="par0210" class="elsevierStylePara elsevierViewall">The authors declare that they have followed the protocols of their centre of work on the publication of patient data.</p></span><span id="sec0050" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0105">Right to privacy and informed consent</span><p id="par0215" class="elsevierStylePara elsevierViewall">The authors have obtained the informed consent of patients and/or subjects referred to in this article.
