The impact of educational interventions on modifiable risk factors for osteoporosis after a fragility fracture

Personalized dietary advices provided by a dietitian increase calcium intake in outpatients with multiple sclerosis-Results from a randomized, controlled, single-blind trial

Background and aims

Multiple sclerosis (MS) is associated with osteoporosis, possibly due to neurological disability and decreased calcium intake. The objective of this study was to evaluate the efficacy of a personalized nutritional advice program by a dietitian compared to the delivery of a standard advice form to optimize dietary calcium intake in outpatients with MS.

Methods

We performed a randomized, controlled, parallel trial comparing the efficacy of a personalized dietary advice (PDA) program to standard advice form (SAF) to increase daily calcium intake in MS patients. The study population was composed by patients with relapsing-remitting MS aged 18-69 years old. PDA program consisted in dietary advice delivered by a dietitian at baseline, 1 month, and 3 months. Calcium and nutrient intake in patients from both groups was evaluated at baseline and 6 months using a dietary survey.

Results

Of the 194 patients screened for inclusion, 182 patients were included (79% female, median age of 42 years, and median EDSS of 2.0), and randomized to SAF (n = 92) or PDA (n = 90). At 6 months, median calcium intake increased by 241 mg/day in the PDA group and decreased by 120 mg/day in the SAF group (p < 0.0001). However, the median calcium intake was 947 mg/day in the SAF group and 778 mg/day in the PDA group at baseline (p = 0.0077), potentially favoring the effect of dietary advice. Complementary analyses focusing on patients with insufficient calcium intakes at baseline revealed comparable values in both groups (p = 0.69). Of those, patients included in the PDA group obtained significantly higher calcium intakes at 6 months than patients from the SAF group (p = 0.0086) independently of EDSS, PASAT, HADS and EQ-5D scores.

Conclusion

This work shows the efficacy of dietary management based on personalized advice program over 3 months to durably increase calcium consumption in MS patients with insufficient calcium intake.

Understanding the Experience of Osteoporosis Risk in Bariatric Surgical Patients

Despite what is known about risk factors, preventive treatment, and increased prevalence of fragility fractures in post-bariatric surgical patients, little is known about how patient perspectives of osteoporosis risk inform their commitment to bone health. The purpose of this study was to examine the lived experience of osteoporosis risk in people who have had bariatric surgery. Interpretive phenomenology was used to explore osteoporosis from the perspectives of patients who have had bariatric surgery. Eligibility criteria included female, age older than 18 years, and able to understand and speak English. This research provided an understanding of the risk of osteoporosis from the constructed realities and experiences of those who have had bariatric surgery. Participants in this study incorrectly felt they had little to no risk for osteoporosis after bariatric surgery. Patients need to be aware of an increased risk for osteoporosis leading to the potential for fragility fractures after bariatric surgery; nurses are well positioned to enhance osteoporosis prevention efforts in this population through pre- and postoperative education.

Educational booklet reinforces knowledge of osteoporosis and influences intentions to improve bone health in previously diagnosed and treated patients

We examined individuals' experiences using an educational booklet developed by the Ontario Osteoporosis Strategy. The booklet appeared to motivate individuals to make changes to their existing management of their bone health and served as a reference tool reaffirming current practices and beliefs for others.

INTRODUCTION

The purpose of this study was to examine individuals' experiences of the educational booklet and explore the influence of the booklet on individuals' beliefs and actions regarding their bone health.

METHODS

Eligible individuals were those who had been prescribed medication to treat low bone mass. One-on-one telephone interviews were conducted over an 18-month period. Participants were interviewed for approximately 1 hour and asked to provide their feedback on the booklet, and to discuss what they were doing with respect to the recommendations made in the booklet.

RESULTS

We interviewed 50 participants who ranged in age from 58 to 89. The overall impression of the booklet was positive. Participants described the language in the booklet as clear and easy to understand. Participants stated that they would have appreciated receiving this tool at the onset of their diagnosis. Forty-two participants had already taken action, or expressed an intention to make changes, to their existing routines to improve their bone health. In contrast, eight participants used the booklet to reaffirm current practices and beliefs. For these individuals, the recommendations made in the booklet were consistent with what they had already been doing.

CONCLUSION

The booklet can engage patients in discussions about bone health. The booklet appeared to motivate individuals to make changes to their existing routines in an effort to achieve better health outcomes for their bone health. Providing a tool like this to people recently diagnosed with a bone health issue may prove to be beneficial.

The Impact of Educational Interventions on Osteoporosis Knowledge among Korean Osteoporosis Patients

Background

The purpose of this study was to determine the impact of an educational intervention that includes information sharing about absolute fracture risk on the knowledge of osteoporosis and modifiable risk factors among Korean patients with osteoporosis.

Methods

Adults aged >50 years who visited the outpatient clinic for osteoporosis were recruited. Subjects with trauma-related fractures or pathological fractures were excluded. The anthropometric data and clinical risk factors for fracture were collected at baseline. The participants completed the survey questionnaire that measured their knowledge regarding osteoporosis at baseline and then received information about the risk of fracture and individual education. Fracture risk was classified into five groups according to degree. The post-survey was conducted 3 months later. The pretest results were compared with the posttest results.

Results

In this study, 179 subjects (15 men and 164 women) were enrolled. After the educational intervention, the mean osteoporosis knowledge score significantly increased from 10.6±5.7 at pre-education (baseline) to 11.7±6.3 at post-education (P<0.001). When comparing the pre- and post-education Korean fracture risk scores, a negligible difference was found between the "very low risk" and "low risk" groups. However, the scores in the "very high risk" and "high risk" groups decreased from 77.6% to 76.0%. We found a difference over time only in physical activity.

Conclusions

Simple educational intervention is effective in increasing osteoporosis knowledge among Korean patients with osteoporosis. It may confer some benefit by providing information about osteoporotic fracture risks to improve knowledge and awareness regarding osteoporosis.

Video-based patient decision aids: A scoping review

OBJECTIVE

This study reviews the published literature on the use of video-based decision aids (DA) for patients. The authors describe the areas of medicine in which video-based patient DA have been evaluated, the medical decisions targeted, their reported impact, in which countries studies are being conducted, and publication trends.

METHOD

The literature review was conducted systematically using Medline, Embase, CINAHL, PsychInfo, and Pubmed databases from inception to 2016. References of identified studies were reviewed, and hand-searches of relevant journals were conducted.

RESULTS

488 studies were included and organized based on predefined study characteristics. The most common decisions addressed were cancer screening, risk reduction, advance care planning, and adherence to provider recommendations. Most studies had sample sizes of fewer than 300, and most were performed in the United States. Outcomes were generally reported as positive. This field of study was relatively unknown before 1990s but the number of studies published annually continues to increase.

CONCLUSION

Videos are largely positive interventions but there are significant remaining knowledge gaps including generalizability across populations.

PRACTICE IMPLICATIONS

Clinicians should consider incorporating video-based DA in their patient interactions. Future research should focus on less studied areas and the mechanisms underlying effective patient decision aids.

Diet and exercise changes following bone densitometry in the Patient Activation After DXA Result Notification (PAADRN) study

Calcium and vitamin D intake and exercise are suboptimal among older adults. Following bone densitometry, a letter communicating individualized fracture risk accompanied by an educational brochure improved participants' lifestyle-but no more than existing communication strategies-over 52 weeks. Simple communication strategies are insufficient for achieving optimal levels of bone health behaviors.

PURPOSE

The Patient Activation After DXA Result Notification (PAADRN) study was designed to evaluate whether a letter with individualized fracture risk and an educational brochure mailed to patients soon after their DXA might improve bone health behaviors (daily calcium intake, vitamin D supplementation, and weekly exercise sessions) compared to slower, less individualized communication characterizing usual care.

METHODS

Participants ≥ 50 years were recruited, at three sites, following their DXA and randomized with 1:1 allocation to intervention and control (usual care only) groups. Data were collected at enrollment interview and by phone survey at 12 and 52 weeks thereafter. Intention-to-treat analyses were conducted on 7749 of the 20,397 eligible participants who enrolled. Changes in bone health behaviors were compared within and between study groups. Average treatment effects and heterogeneity of treatment effects were estimated with multivariable linear and logistic regression models.

RESULTS

In unadjusted analyses, calcium intake, vitamin D supplementation, and weekly exercise sessions increased significantly over 52 weeks within both the intervention and control groups (all p < 0.001). In unadjusted analyses and multivariable models, increases in each behavior did not significantly differ between the intervention and control groups. Intervention group participants with a > 20% 10-year fracture risk at enrollment did, however, have a significantly greater increase in calcium intake compared to other study participants (p = 0.031).

CONCLUSIONS

Bone health behaviors improved, on average, over 52 weeks among all participants following a DXA. Receipt of the PAADRN letter and educational brochure did not directly improve bone health behaviors compared to usual care.

A review of lifestyle, smoking and other modifiable risk factors for osteoporotic fractures

Although many strong risk factors for osteoporosis-such as family history, fracture history and age-are not modifiable, a number of important risk factors are potential targets for intervention. Thus, simple, non-pharmacological intervention in patients at increased risk of osteoporotic fractures could include reduction of excessive alcohol intake, smoking cessation, adequate nutrition, patient education, daily physical activity and a careful review of medications that could increase the risk of falls and fractures. There remains, however, an unmet need for high-quality intervention studies in most of these areas.
