Description of intervention(s) / exposure
This study will evaluate the use of a Google-Translated patient education website following standard informed consent for surgery process, to assess if it can improve non-English-speaking patient knowledge compared to the standard surgical consent process.
The intervention will be the use of a Google-translated patient education website (orthoanswer.org). The researcher will provide participants in the intervention group with access to the Orthoanswer web page with information specific to their operation (total hip or knee replacement) translated in their preferred language using a Google Translate widget. The content provided on the patient education website includes information on diagnosis, alternative interventions, benefits of surgical intervention, post-operative expectations, potential risks and complications, what to expect before, during and after surgery and recovery and rehabilitation,
Participants will be given up to 30 minutes to read the content. Patients will have an interpreter present and available for any questions that may arise. In order to monitor adherence to the intervention, patients will be supervised by research staff and a timer set to 30minutes will be used to track the period of reading and viewing the content.

Comparator / control treatment
Current standard practice at our institution for surgical consent for non-English speaking patients is a discussion between the surgeon and the patient with an interpreter. No additional patient education resources (i.e. Google-translated patient education website: orthoanswer.org) are routinely provided.

Patient knowledge
Query!
Assessment method [1]

0
All participants in the study will be required to complete the same Patient Knowledge Test with questions specific to their operation (total hip replacement or total knee replacement). The Patient Knowledge Test questionnaires were designed specifically for this study.
Patient knowledge scores (0–100%) based on the percentage of questions answered correctly on an operation-specific knowledge test (Total Hip Replacement Knowledge Test and Total Knee Replacement Knowledge Test). The test is standardised to assess patient knowledge of key components to ensure surgical consent is valid including: diagnosis, procedure, indication, benefits, risks, recovery and alternatives.
The Patient Knowledge Questionnaires will be translated by a qualified translation company into three of the languages most commonly spoken by WH patients (Arabic, Punjabi and Vietnamese). Patients who speak one of the languages that is not translated will have a qualified interpreter to assist them to complete the knowledge questionnaire with the researcher.

Assessed using the ‘Client Satisfaction Questionnaire: CSQ-8’. All patients are required to complete the questionnaire after the patient knowledge test. The questionnaire is expected to take approximately 5 minutes to complete. It is translated into 50+ languages and available in many of the common languages spoken by Western Health patients (Arabic, Cantonese, Greek, Italian, Spanish and Vietnamese). The patient satisfaction score ranges from 4 to 32.

Statistical methods / analysis
The statistical analysis will consist of descriptive statistics such as mean, median, standard deviations, frequencies, proportions etc. to describe the results and graphical representations can be made were applicable to assist in visualizing aspects of the data.
Inferential investigations may include tests like the Chi-squared test to compare the results, between the Control and Intervention arms, for the categorical outcomes. Numerical outcomes will be investigated for normality and may include tests like the independent t-test or the Mann Whitney U test (the nonparametric alternative). Additional regression models may be considered to adjust for certain baseline characteristics (such as age, language, education level and operation). All significance tests will be performed at a 5% level of significance.
Using information from a similar study (Fraval, et al., 2015), which also measured the patient knowledge score on a relatively similar subset of patients and showed a large effect size of 1.36 (intervention arm had an average score of 69.25 [SD 14.91] with the control arm 47.38 [SD 17.11]), a sample size calculation using G*Power Version 3.1.9.6 (24, 25), testing at a 5% level of significance and a power of 80%, showed that at least 8 participants will be required per group. Data will be collected for a 12-month period, with a minimum number of participants being collected per group set at 18 (total of 36). A slightly larger sample of participants will be collected to account for the slight differences between the study sample and those of the study. This slightly larger sample will also account for any dropouts even though this is expected to be very small due to the nature in which the data will be collected.

Summary
Brief summary
This randomised controlled trial aims to find out whether a patient education website, translated into patients' preferred language using Google translate, improves the knowledge of non-English-speaking (NES) patients during the surgical consent process. Previous studies have shown that patient education websites improves patient knowledge of their planned orthopaedic surgery in English-speaking patients. Non-English speaking patients are more likely to have poorer health understanding and a less thorough informed consent for surgery. We do not know if an education website translated using Google Translate is helpful for non-English speaking patients. We are using Google Translate for this purpose because it translates instantly for free and is easily available to both patients and doctors. We are hoping that this will improve care by increasing both patient knowledge and satisfaction during the process of informed consent for surgery for patients who do not speak English.
