Evaluation of Osteoporosis Risk Assessment in Veterans Receiving Androgen-Deprivation Therapy

Bone health management in men undergoing ADT: examining enablers and barriers to care

The study determined prostate cancer specialists' knowledge and concordance to guidelines regarding the diagnosis, management, and prevention of androgen deprivation therapy-induced osteoporosis. Despite high knowledge regarding bone health, most respondents did not routinely measure bone mineral density or use fracture risk assessment tools, suggesting a significant gap in the screening/monitoring of bone health.

INTRODUCTION

The purpose of this study was to determine prostate cancer specialists' knowledge, practices, self-perceived competencies and barriers to providing guideline-concordant care in the diagnosis, prevention, and management of androgen deprivation therapy (ADT)-induced osteoporosis (OP).

METHODS

A number of 73 Canadian radiation oncologists and 83 urologists completed questionnaires assessing (i) knowledge regarding OP and consensus guidelines for bone health management in men receiving ADT, (ii) self-assessed competencies regarding bone health management, (iii) current practices regarding OP prevention and management, and (iv) self-perceived barriers to providing guideline-concordant care.

RESULTS

The majority of respondents were able to correctly identify the guideline-concordant frequency of repeat dual-energy X-Ray absorptiometry (DXA) scans (76.3%), vitamin D (70.3%), and calcium (53.2%) intake and that bisphosphonates/denosumab should always be considered for patients with a history of one low-trauma fracture (57.6%). Just under 1/3 (32.5%) reported routinely measuring bone mineral density (BMD) prior to starting ADT and routinely measuring BMD 1-2 years following the initiation of ADT (36.6%). Only 4.6% of respondents routinely used a validated fracture risk assessment tool. Lowest self-assessed competency levels were reported in providing self-management education to patients to foster the uptake of healthy bone behaviors (HBBs) and managing patients who present with or develop osteopenia and OP. The most significant barriers to providing OP prevention and management were lack of time and lack of supporting structures.

CONCLUSIONS

Despite high knowledge about appropriate bone health care among prostate cancer specialists, there remain significant gaps in screening and monitoring of bone health, suggesting the need to develop innovative strategies to overcome barriers to implementation.

Designing a resident research program

PURPOSE

The development of a resident research program and the role of the residency research advisory board (RRAB) in the program are described.

SUMMARY

Over the past decade, there have been numerous barriers to successfully implementing a residency research program. An RRAB was subsequently developed to assist with research mentoring to help prepare residents to incorporate research into future positions. Within this board, one clinical pharmacy practitioner or preceptor serves as the research coordinator and acts as chair and liaison to the institutional review board (IRB) and research and development (R&D) committee. All members of the RRAB function as research experts in various aspects of the research process. The RRAB comprises three members to navigate IRB and R&D paperwork, generate and develop research ideas, create relationships with institutional research committees, educate pharmacy residents in a consistent manner on research methods in a longitudinal fashion, provide mentorship to preceptors, and facilitate service-related communication on our research timelines, plans, local and distant presentations, and other related efforts. The development of the resident research program and the RRAB have resulted in an improvement in the level of research conducted by our residents and preceptors. Due to the support of the RRAB, residents are submitting and presenting posters at local, state, and national meetings as well as submitting manuscripts to and publishing manuscripts in health care journals.

CONCLUSION

Development of an RRAB increased residents' manuscript publication and poster presentation rates and facilitated the research process.

The impact of bone mineral density testing, fracture assessment, and osteoporosis education in men treated by androgen deprivation for prostate cancer: a pilot study

PURPOSE

Men receiving androgen deprivation therapy for prostate cancer have low knowledge of osteoporosis (OP) and engage in few healthy bone behaviors (HBBs). A multicomponent intervention was piloted in this population. Changes in OP knowledge, self-efficacy, health beliefs, and engagement in HBBs were evaluated.

METHODS

A pre-post pilot study was performed in a convenience sample of men recruited from the Princess Margaret Cancer Centre. Men were sent personalized letters explaining their dual x-ray absorptiometry (DXA) results and fracture risk assessment with an OP-related education booklet. Participants completed questionnaires assessing OP knowledge, self-efficacy, health beliefs, and current engagement in HBBs at baseline (T1) and 3 months post-intervention (T2). Paired t tests and McNemar's test were used to assess changes in outcomes.

RESULTS

A total of 148 men completed the study. There was an increase in OP knowledge (9.7 ± 4.3 to 11.4 ± 3.3, p < 0.0001) and feelings of susceptibility (16.5 ± 4.3 to 17.4 ± 4.7, p = 0.015), but a decrease in total self-efficacy (86.3 ± 22.9 to 81.0 ± 27.6, p = 0.007) from baseline to post-intervention. Men made appropriate changes in their overall daily calcium intake (p ≤ 0.001), and there was uptake of vitamin D supplementation from 44 % (n = 65) to 68 % (n = 99) (p < 0.0001). Men with bone loss (osteopenia or OP) had a greater change in susceptibility (1.9 ± 4.3 vs. -0.22 ± 4.2, p = 0.005) compared to men with normal bone density.

CONCLUSIONS

Our results provide preliminary evidence that a multicomponent intervention such as the one described can lead to increased knowledge and feelings of susceptibility regarding OP and can enhance uptake of some HBBs.

Osteoporosis knowledge, health beliefs, and healthy bone behaviours in patients on androgen-deprivation therapy (ADT) for prostate cancer

OBJECTIVES

To describe in patients with prostate cancer, receiving androgen-deprivation therapy (ADT): (i) knowledge, self-efficacy (SE), and health beliefs about osteoporosis (OP); (ii) current engagement in healthy bone behaviours (HBBs). To explore the relationships between knowledge, SE, and health beliefs, and engagement in HBBs.

PATIENTS AND METHODS

175 patients receiving ADT by injection completed questionnaires assessing current HBBs, OP knowledge, SE, and health beliefs (motivation, perceived susceptibility, and seriousness). Descriptive statistics and independent samples t-tests were used to assess relationships between knowledge, SE, health beliefs, and engagement in HBBs.

RESULTS

Only 38% of patients had undergone a dual X-ray absorptiometry scan in the past 2 years. OP knowledge was low (mean [sd, range] 9.6 [4.4, 0-19]) and perceived SE moderate (84.7 [24.5, 0-120]). Health motivation was fairly high (23.6 [3.1, 6-30]), but perceived susceptibility (16.8 [4.3]) and seriousness (16.8 [4.2]) of OP were low. Few patients met the recommendations for vitamin D intake (42%) and exercise (31%), and 15% were at risk of over-supplementation of calcium. Patients taking calcium supplements (P = 0.04), and meeting guidelines for vitamin D (P = 0.008) and for exercise (P = 0.002) had significantly greater knowledge than those who did not. Patients who were engaging in less than four of five HBBs had lower knowledge (P < 0.001) and health motivation (P = 0.01) than those who were engaging in four or all five HBBs.

CONCLUSIONS

Most patients who are receiving ADT are not receiving appropriate screening, lack basic information about bone health, and are not engaging in the appropriate HBBs. These findings support the application of the Health Belief Model in this population: interventions that teach patients about the implications of bone loss, encourage proper uptake of HBBs, and promote feelings of SE could increase engagement in HBBs to prevent and manage bone loss.
