Effekten av digital utbildning för osteoporospatienter på frakturrisk och relaterade hälsoresultat.

The hypothesis is that improved patient education using an easily accessible online educational material will result in better adherence to osteoporosis medication and positive lifestyle changes, which will lead to a lower risk of fractures and injurious falls. The primary aim of this study is to investigate if a Digital Education for Osteoporosis Patients (DEOP) affects the risk of sustaining a clinical fracture in patients over the age of 65 who have been recommended osteoporosis treatment after a bone density (DXA) scan. The secondary aims are to investigate if DEOP affects the risk of injurious falls, adherence to osteoporosis medications, improves dietary intake and quality of life, and increases physical activity compared to standard care.

The planned study is a multicentre randomized controlled trial, with 9 participating study centers (osteoporosis clinics). Patients who have not previously received osteoporosis medication the last year and are over the age of 65 visiting an osteoporosis clinic for a clinical evaluation, including a bone density scan (DXA) and assessment of clinical risk factors and fracture risk, will be asked to participate in the study. Before the appointment for the DXA measurement, possible study participants will receive written information about the study by mail. At the visit, oral information about the study will be provided by the bone densitometry technologist. Written information will be distributed to possible participants that have not previously received the information. The patients must have the opportunity to ask questions before they make their decision to participate or not. Acceptance to participate must be communicated both verbally and through signing an informed consent form. All patients will undergo a DXA-scan and answer a questionnaire regarding clinical risk factors included in the fracture risk assessment tool FRAX, according to local clinical guidelines.

At a later stage, if the patient, by the doctor at the osteoporosis clinic, is recommended pharmacological treatment for osteoporosis (due to a high fracture risk), the patient becomes eligible for the study. If the patient does not have an indication to receive osteoporosis medication, as judged by the physician at the osteoporosis unit, the patient will be excluded from the study as screening failure and receive a notification of this through e-mail or regular mail.

Patients eligible for the study will be randomized, stratified according to sex and study center, into one of two arms where patients in one arm will be invited to the DEOP and patients in the other arm will receive standard care, without the DEOP. Patients in both groups will be treated and followed according to clinical guidelines for osteoporosis care in their health care region, by either a general practitioner (GP) or a doctor at an osteoporosis clinic. Only osteoporosis clinics without an ongoing DEOP will be eligible as study clinics in these health care regions. After randomization, the local study coordinator will contact all included patients through e-mail or regular mail and ask them to complete self-reported questionnaires regarding physical activity, diet, and quality of life (Physical Activity Scale for the Elderly (PASE), Food Frequency Questionnaire (FFQ), and quality of life (Short Form survey, SF-12), respectively). Data regarding clinical risk factors (and calculated 10-year probability of major osteoporotic fracture and hip fracture) in the fracture risk assessment tool FRAX, height, and weight, and bone mineral density (BMD; of the lumbar spine, total hip, and femoral neck, in grams/cm2 and as T-scores) will be collected from the osteoporosis clinic by the local study coordinator or other study personnel. After years 1 and 3, an e-mail or regular mail (if the study participant does not use e-mail) will be sent to the participants and they will be asked to answer the same questionnaires again. Data regarding clinical fractures will be collected from the Patient Register (Socialstyrelsen, the National Board of Health and Welfare), the Swedish Fracture Register, and from regional X-ray archives after the end of the study (maximum 4 years of follow-up). Data on the incidence of injurious falls (including injuries without fracture) will be collected through the Patient Register at the end of the study. Data on osteoporosis medication use will be collected from the Drug Dispensation Register and regional databases regarding medications provided at health care facilities at the end of the study. Data on deaths will be collected using the National Cause of Death Register. Data on diagnoses and medication will be collected five years back from the inclusion date to determine comorbidity.

The participants in the DEOP group will be given access to the DEOP for four months after randomization. Reminders will be sent out using phone text messages monthly for the first 3 months to participants who have not yet started the DEOP. The control group will be given information regarding fall prevention, physical activity, diet, and osteoporosis medication according to standard care, by their GP or the physician at the osteoporosis clinics, depending on where they are treated for their osteoporosis.
