Effects of a DXA result letter on satisfaction, quality of life, and osteoporosis knowledge: a randomized controlled trial

Effect of coordinator-based osteoporosis intervention on quality of life in patients with fragility fractures: a prospective randomized trial

We examined the effects of the coordinator-based intervention on quality of life (QOL) in the aftermath of a fragility fracture, as well as factors predictive of post-fracture QOL. The coordinator-based interventions mitigated the decrease in QOL. Secondary fracture after primary fracture, however, was a significant predictor of lower QOL.

PURPOSE

This study aimed to determine the effects of the coordinator-based intervention on QOL in the aftermath of a fragility fracture, as well as factors predictive of post-fracture QOL, in an Asian population.

METHODS

Patients with new fractures in the intervention group received the coordinator-based intervention by a designated nurse certified as a coordinator, within 3 months of injury. QOL was evaluated using the Japanese version of the EuroQol 5 Dimension 5 Level (EQ-5D-5L) scale  before the fracture (through patient recollections) and at 0.5, 1, and 2 years after the primary fracture.

RESULTS

Data for 141 patients were analyzed: 70 in the liaison intervention (LI) group and 71 in the non-LI group. Significant intervention effects on QOL were observed at 6 months after the fracture; the QOL score was 0.079 points higher in the LI group than in the non-LI group (p=0.019). Further, the LI group reported significantly less pain/discomfort at 2 years after the fracture, compared to the non-LI group (p=0.037). In addition, secondary fractures were found to significantly prevent improvement and maintenance of QOL during the recovery period (p=0.015).

CONCLUSION

Short-term intervention effects were observable 6 months after the primary fracture, with the LI group mitigated the decrease in QOL. Few patients in the LI group reported pain/discomfort 2 years after the fracture, but there is uncertainty regarding its clinical significance. Secondary fracture after initial injury was a significant predictor of lower QOL after a fracture.

Measuring Health-Related Quality of Life in Randomised Controlled Trials: Expected and Reported Results Do Not Match

Purpose

The assessment of health-related quality of life (hrQoL) may need to be reconsidered due to important differences between efficacy (the effect of a treatment under experimental study conditions) and effectiveness (the effect of a treatment under real-world conditions). We presume that most researchers intend to describe effects under real-world conditions when investigating hrQoL as an endpoint. Unfortunately, most studies are designed to confirm two theories: the efficacy of a new intervention under experimental study conditions and the real-world effectiveness of this intervention on hrQoL under non-experimental study conditions. Conflicting information emerges when the outcomes are supposed to describe effects under real-world conditions, but the assessment generates results obtained under experimental conditions. This paper examines the existing conflict between efficacy and effectiveness in a sample of 100 studies investigating hrQoL.

Methods

We analysed a sample of freely available publications of clinical studies listed in PubMed between April 2015 and August 2016 which assessed quality of life as an outcome. We assessed the following four characteristics that should differ in studies measuring either efficacy or effectiveness: 1) specification of the study as a randomised controlled trial or not, 2) description of the study design as pragmatic or not, 3) classification of the study as an efficacy or an effectiveness study and 4) number of selected inclusion and exclusion criteria.

Results

91% of the studies assessed hrQoL under experimental conditions (in a randomised controlled trial), but not under real-world conditions. The important difference between efficacy and effectiveness was not described in 60% of the studies. Only 6% of studies classified the study as a pragmatic trial. The difference between inclusion and exclusion criteria was not addressed in any of the investigated studies.

Conclusion

The results of the four criteria confirmed our hypothesis that hrQoL studies are conducted mainly as experimental, but not pragmatic, trials indicating that the meaningfulness of the important difference between efficacy and effectiveness requires further discussion.

Resources and competencies for management of educational practices by nurses: integrative review

OBJECTIVE

To know the resources used and the necessary skills to the nurse for the management of educational practices in health services.

METHOD

This is an integrative literature review, carried out in the Latin American and Caribbean databases on Health Sciences Information (BIREME), PubMed Central (PMC), Scopus and Web of Science (WoS). After analysis resulted in 18 studies, published between the period 2011 to 2017, which were presented in three categories.

RESULTS

The results were presented in the categories: instrumental resources used in health education, technological resources applied to educational practices and competencies for management of educational practices.

CONCLUSION

This study brings as a contribution to the practice of nurses subsidies for the development of management of educational practices in health services through technological and instrumental resources and professional skills that aim at team development, user autonomy and institutional growth.

The prevalence of overtreatment of osteoporosis: results from the PAADRN trial

Overtreatment of osteoporosis increases costs and puts patients at unnecessary risk of experiencing adverse drug events. In the Patient Activation After DXA Receipt Notification (PAADRN) trial, we found that 8% of individuals with no indication for therapy were recommended a new osteoporosis medication or continuation of an existing medication.

PURPOSE

There is a robust body of literature addressing undertreatment in osteoporosis, but limited data addressing overtreatment. Understanding overtreatment is important to minimize harm and decrease costs.

METHODS

One of the pre-specified post hoc analyses of the PAADRN trial, a randomized, controlled, pragmatic clinical trial, was to quantify and identify risk factors associated with osteoporosis overtreatment. PAADRN included patients ≥ 50 years of age presenting for bone density testing between February, 2012, and August, 2014, at three US healthcare systems. We assessed 20,397 patients for eligibility and randomized 7749. Intervention patients received a tailored letter containing their dual-energy X-ray absorptiometry (DXA) results and an educational osteoporosis brochure. Control patients received usual care. Using the National Osteoporosis Foundation treatment guidelines, we defined overtreatment as the receipt of osteoporosis pharmacotherapy 12 weeks after DXA when treatment was not indicated. We evaluated the relationship between the following baseline variables-sex, race/ethnicity, educational attainment, and differences across health systems-and overtreatment using a series of multivariable logistic regression models.

RESULTS

Among 3602 patients with no apparent indication for osteoporosis treatment, 292 (8.1%; 95% CI, 7.22 to 9.00%) received a new prescription for osteoporosis pharmacotherapy or were instructed to continue an existing medication (presumed overtreatment). Presumed overtreatment was more common among participants with prior DXA history, those who reported a history of osteoporosis or low bone mass, and those referred for testing by family medicine providers.

CONCLUSION

In our sample of older adults, overuse of osteoporosis pharmacotherapy was only 8.1%. Nevertheless, overtreatment exposes patients to possible risk with negligible chance of benefit and should be minimized.

Validity, reliability, and responsiveness to change of the "Osteoporosis and You" knowledge scale

We studied the Osteoporosis and You knowledge scale in 7749 participants enrolled in a clinical trial. Results confirmed its psychometric properties in a diverse audience. Baseline scores were associated with better recall of bone mineral density test results at follow-up; however, the scale was not responsive to knowledge change.

INTRODUCTION

The goal of this study was to confirm the measurement properties of the Osteoporosis and You (O&Y) knowledge scale using classic test theory methods in the 7749 men and women participating in the Patient Activation After DXA Result Notification (PAADRN) randomized controlled trial. We hypothesized a simple factor structure that would reflect the four-factor model previously published.

METHODS

We conducted psychometric analyses which included item analysis, internal consistency reliability, construct validity using exploratory and confirmatory factor analysis (EFA and CFA), comparing knowledge levels across pre-specified groups, and responsiveness to change.

RESULTS

PAADRN participants were predominantly college educated, White females with low bone density, and a moderate level of 10-year fracture risk. EFA revealed four domains closely matching those in two previous reports. While overall scale reliability was minimally acceptable at 0.68, the reliabilities of the domain subscales were unacceptably low (0.59, 0.64, 0.45, and 0.36 for the Biological, Lifestyle, Consequences, and Prevention and Treatment subscales). CFA revealed the data fit the hypothesized model reasonably well with the items loading on their expected latent variable. The scale was not responsive to change, but although not significant, improved knowledge indicated better DXA result recall at 12 and 52 weeks.

CONCLUSIONS

In the PAADRN population, the O&Y knowledge scale had psychometric properties similar to those previously reported. Over 12 and 52 weeks, participants did not demonstrate significant changes in knowledge, but those with higher knowledge at baseline were more likely to accurately recall their baseline DXA result.

The cost of a patient activation intervention for achieving successful outcomes: results from the PAADRN randomized controlled trial

In a large, pragmatic clinical trial, we calculated the costs of achieving four successful patient-centered outcomes using a tailored patient activation DXA result letter accompanied by a bone health brochure. The cost to achieve one successful outcome (e.g., a 0.5 standard deviation improvement in care satisfaction) ranged from $127.41 to $222.75.

INTRODUCTION

Pragmatic randomized controlled trials (RCTs) should focus on patient-centered outcomes and report the costs for achieving those outcomes. We calculated per person incremental intervention costs, the number-needed-to-treat (NNT), and incremental per patient costs (cost per NNT) for four patient-centered outcomes in a direct-to-patient bone healthcare intervention.

METHODS

The Patient Activation after DXA Result Notification (PAADRN) pragmatic RCT enrolled 7749 patients presenting for DXA at three health centers between February 2012 and August 2014. Interviews occurred at baseline and 52 weeks post-DXA. Intervention subjects received an individually tailored DXA result letter accompanied by an educational bone health brochure 4 weeks post-DXA, while the usual care subjects did not. Outcomes focused on patients (a) correctly identifying their results, (b) contacting their providers, (c) discussing their results with their providers, and (d) satisfaction with their bone healthcare. NNTs were determined using intention-to-treat linear probability models, per person incremental intervention costs were calculated, and costs per NNT were computed.

RESULTS

Mean age was 66.6 years old, 83.8% were women, and 75.3% were non-Hispanic whites. The incremental per patient cost (costs per NNT) to increase the ability of a patient to (a) correctly identify their DXA result was $171.07; (b) contact their provider about their DXA result was $222.75; (c) discuss their DXA result with their provider was $193.55; and (d) achieve a 0.5 SD improvement in satisfaction with their bone healthcare was $127.41.

CONCLUSION

An individually tailored DXA result letter accompanied by an educational brochure can improve four patient-centered outcomes at a modest cost.

The effects of a patient activation intervention on smoking and excessive drinking cessations: results from the PAADRN randomized controlled trial

Patients may exhibit risky bone health behaviors. In a large pragmatic clinical trial, we tested whether a tailored patient activation DXA result letter accompanied by a bone health brochure led to smoking and excessive drinking cessations. The intervention did not, however, alter these risky bone health behaviors.

INTRODUCTION

Besides dual-energy x-ray absorptiometry (DXA) screening and pharmacotherapy when indicated, beneficial bone health behaviors including proper calcium and vitamin D intake and weight-bearing and muscle-strengthening exercise should be encouraged. Similarly, risky bone health behaviors like smoking and excessive drinking should be discouraged. We examined whether a direct-to-patient activation intervention led to smoking and excessive drinking cessations.

METHODS

The Patient Activation after DXA Result Notification (PAADRN) pragmatic clinical trial enrolled 7749 patients between February 2012 and August 2014. Interviews occurred at baseline and 12 and 52 weeks later. Intervention subjects were mailed an individually tailored DXA results letter accompanied by a bone health educational brochure 4 weeks post-DXA. Usual care subjects were not sent these materials. Smoking and excessive drinking were assessed by self-report at each interview. Intention-to-treat linear probability models were used.

RESULTS

Mean age was 66.6 years, 83.8% were women, and 75.3% were Non-Hispanic-Whites. Smoking was reported at baseline by 7.6% of the intervention group vs. 7.7% of the usual care group (p = 0.873). Excessive drinking was reported at baseline by 6.5% of the intervention group vs. 6.5% of the usual care group (p = 0.968). Intention-to-treat analyses indicated no significant differences between the intervention vs. usual care groups at either 12 or 52 weeks post-DXA (all p values ≥ 0.346).

CONCLUSION

An individually tailored DXA result letter accompanied by an educational brochure did not lead to smoking or excessive drinking cessations in patients who received DXA.

Evaluation of a "Just-in-Time" Nurse Consultation on Bone Health: A Pilot Randomized Controlled Trial

CONTEXT

Evidence is inconclusive whether a nurse consultation can improve osteoporosis-related patient outcomes.

OBJECTIVE

To evaluate whether a nurse consultation immediately after dual-energy x-ray absorptiometry (DXA) produced better osteoporosis-related outcomes than a simple intervention to activate adults in good bone health practices or usual care.

DESIGN

Pilot randomized controlled trial, conducted within the larger Patient Activation After DXA Result Notification (PAADRN) trial (NCT01507662). After DXA, consenting adults age 50 years or older were randomly assigned to 3 groups: nurse consultation, PAADRN intervention (mailed letter with individualized fracture risk and an educational brochure), or usual care (control). Nurse consultation included reviewing DXA results, counseling on bone health, and ordering needed follow-up tests or physician referrals.

MAIN OUTCOME MEASURES

Change from baseline to 52 weeks in participant-reported osteoporosis-related pharmacotherapy, lifestyle, activation and self-efficacy, and osteoporosis care satisfaction.

RESULTS

Nurse consultation participants (n = 104) reported 52-week improvements in strengthening and weight-bearing exercise (p = 0.09), calcium intake (p < 0.01), osteoporosis knowledge (p = 0.04), activation (p < 0.01), dietary self-efficacy (p = 0.06), and osteoporosis care satisfaction (p < 0.01). Compared with PAADRN intervention participants (n = 39), nurse consultation participants had improved dietary self-efficacy (p = 0.07) and osteoporosis care satisfaction (p = 0.05). No significant improvements in osteoporosis-related outcomes were achieved vs PAADRN controls (n = 70).

CONCLUSION

"Just-in-time" nurse consultation yielded a few improvements over 52 weeks in osteoporosis-related outcomes; however, most changes were not different from those obtained through the lower-cost PAADRN intervention or usual care.

Patient-reported reasons for nonadherence to recommended osteoporosis pharmacotherapy

OBJECTIVES

As many as one-half of patients recommended for osteoporosis pharmacotherapy do not take their medications. To identify intervention targets, we examined patient characteristics associated with nonadherence to recommended pharmacotherapy and their reasons for nonadherence.

METHODS

Data come from the Patient Activation after DXA Result Notification (PAADRN) study, a randomized controlled trial of 7749 patients aged 50 years or older presenting for dual-energy X-ray absorptiometry (DXA) at 3 health centers in the United States. We focused on the 790 patients who reported receiving a recommendation for new pharmacotherapy at baseline. Using Pearson chi-squared tests for categorical variables, 2-sample t tests for continuous variables, and multivariable multinomial logistic regression, we compared those who reported starting the recommended medication (adherers) with temporary nonadherers and nonadherers on demographics, health habits, DXA impression, 10-year probability of fracture using the assessment tool, and osteoporosis knowledge, and we examined their stated reasons for nonadherence.

RESULTS

Mean age was 66.8 years (SD = 8.9); 87.2% were women, and 84.2% were white. One-fourth of patients (24.8%) reported that they did not start their recommended pharmacotherapy. In the unadjusted analyses, the only factor significantly associated with nonadherence was osteoporosis knowledge, with those having better knowledge being less likely to take their medications (P < 0.05). The most common reasons for nonadherence were fear of adverse effects (53.3%), a dislike of taking medicine (25.3%), and the belief that the medication would not help their condition (16.7%).

CONCLUSION

One in 4 patients recommended for osteoporosis pharmacotherapy declined treatment because they feared potential adverse effects, did not like taking medicine, or believed that the medication would not help their condition. Improved patient counseling on the potential adverse effects of osteoporosis treatment and the risk-benefit ratio for these medications may increase adherence.

Racial Differences and Disparities in Osteoporosis-related Bone Health: Results From the PAADRN Randomized Controlled Trial

BACKGROUND

Determining whether observed differences in health care can be called disparities requires persistence of differences after adjustment for relevant patient, provider, and health system factors. We examined whether providing dual-energy x-ray absorptiometry (DXA) test results directly to patients might reduce or eliminate racial differences in osteoporosis-related health care.

DESIGN, SUBJECTS, AND MEASURES

We analyzed data from 3484 white and 1041 black women who underwent DXA testing at 2 health systems participating in the Patient Activation after DXA Result Notification (PAADRN) pragmatic clinical trial (ClinicalTrials.gov NCT-01507662) between February 2012 and August 2014. We examined 7 outcomes related to bone health at 12 weeks and 52 weeks post-DXA: (1) whether the patient correctly identified their DXA baseline results; (2) whether the patient was on guideline-concordant osteoporosis pharmacotherapy; (3) osteoporosis-related satisfaction; (4) osteoporosis knowledge; (5 and 6) osteoporosis self-efficacy for exercise and for diet; and (7) patient activation. We examined whether unadjusted differences in outcomes between whites and blacks persisted after adjusting for patient, provider, and health system factors.

RESULTS

Mean age was 66.5 years and 29% were black. At baseline black women had less education, poorer health status, and were less likely to report a history of osteoporosis (P<0.001 for all). In unadjusted analyses black women were less likely to correctly identify their actual DXA results, more likely to be on guideline-concordant therapy, and had similar patient activation. After adjustment for patient demographics, baseline health status and other factors, black women were still less likely to know their actual DXA result and less likely to be on guideline-concordant therapy, but black women had greater patient activation.

CONCLUSIONS

Adjustment for patient and provider level factors can change how racial differences are viewed, unmasking new disparities, and providing explanations for others.
