Measuring patient perceptions about osteoporosis pharmacotherapy

Abstract Background Adherence to osteoporosis pharmacotherapy is poor, and linked with patient perceptions of the benefits of, and barriers to taking these treatments. To better understand the association between patient perceptions and osteoporosis pharmacotherapy, we generated thirteen items that may tap into patient perceptions about the benefits of, and barriers to osteoporosis treatment; and included these items as part of a standardized telephone interview of women aged 65–90 years (n = 871). The purpose of this paper is to report the psychometric evaluation of our scale. Findings Upon detailed analysis, six of the thirteen items were omitted: four redundant, one did not correlate well with any other item and one factorial complex. From the remaining seven items, two distinct unidimensional domains emerged (variance explained = 78%). Internal consistency of the 5-item osteoporosis drug treatment benefits domain was good (Cronbach's alpha = 0.88), and was supported by construct validity; women reporting a physician-diagnosis or taking osteoporosis pharmacotherapy had higher osteoporosis treatment benefit scores compared to those reporting no osteoporosis diagnosis or treatment respectively. Because only two items were identified as tapping into treatment barriers, we recommend they each be used as a separate item assessing potential barriers to adherence to osteoporosis pharmacotherapy, rather than combined into a single scale. Conclusion The 5-item osteoporosis drug treatment benefits scale may be useful to examine perceptions about the benefits of osteoporosis pharmacotherapy. Further research is needed to develop scales that adequately measure perceived barriers to osteoporosis pharmacotherapy

Predictors of locating women six to eight years after contact: internet resources at recruitment may help to improve response rates in longitudinal research

<p>Abstract</p> <p>Background</p> <p>The ability to locate those sampled has important implications for response rates and thus the success of survey research. The purpose of this study was to examine predictors of locating women requiring tracing using publicly available methods (primarily Internet searches), and to determine the additional benefit of vital statistics linkages.</p> <p>Methods</p> <p>Random samples of women aged 65–89 years residing in two regions of Ontario, Canada were selected from a list of those who completed a questionnaire between 1995 and 1997 (n = 1,500). A random sample of 507 of these women had been searched on the Internet as part of a feasibility pilot in 2001. All 1,500 women sampled were mailed a newsletter and information letter prior to recruitment by telephone in 2003 and 2004. Those with returned mail or incorrect telephone number(s) required tracing. Predictors of locating women were examined using logistic regression.</p> <p>Results</p> <p>Tracing was required for 372 (25%) of the women sampled, and of these, 181 (49%) were located. Predictors of locating women were: younger age, residing in less densely populated areas, having had a web-search completed in 2001, and listed name identified on the Internet prior to recruitment in 2003. Although vital statistics linkages to death records subsequently identified 41 subjects, these data were incomplete.</p> <p>Conclusion</p> <p>Prospective studies may benefit from using Internet resources at recruitment to determine the listed names for telephone numbers thereby facilitating follow-up tracing and improving response rates. Although vital statistics linkages may help to identify deceased individuals, these may be best suited for post hoc response rate adjustment.</p

Decision to take osteoporosis medication in patients who have had a fracture and are 'high' risk for future fracture: A qualitative study

Abstract Background Patients' values and preferences are fundamental tenets of evidence-based practice, yet current osteoporosis (OP) clinical guidelines pay little attention to these issues in therapeutic decision making. This may be in part due to the fact that few studies have examined the factors that influence the initial decision to take OP medication. The purpose of our study was to examine patients' experiences with the decision to take OP medication after they sustained a fracture. Methods A phenomenological qualitative study was conducted with outpatients identified in a university teaching hospital fracture clinic OP program. Individuals aged 65+ who had sustained a fragility fracture within 5 years, were 'high risk' for future fracture, and were prescribed OP medication were eligible. Analysis of interview data was guided by Giorgi's methodology. Results 21 patients (6 males, 15 females) aged 65-88 years participated. All participants had low bone mass; 9 had OP. Fourteen patients were taking a bisphosphonate while 7 patients were taking no OP medications. For 12 participants, the decision to take OP medication occurred at the time of prescription and involved minimal contemplation (10/12 were on medication). These patients made their decision because they liked/trusted their health care provider. However, 4/10 participants in this group indicated their OP medication-taking status might change. For the remaining 9 patients, the decision was more difficult (4/9 were on medication). These patients were unconvinced by their health care provider, engaged in risk-benefit analyses using other information sources, and were concerned about side effects; 7/9 patients indicated that their OP medication-taking status might change at a later date. Conclusions Almost half of our older patients who had sustained a fracture found the decision to take OP medication a difficult one. In general, the decision was not considered permanent. Health care providers should be aware of their potential role in patients' decisions and monitor patients' decisions over time

Social role participation and the life course in healthy adults and individuals with osteoarthritis: Are we overlooking the impact on the middle-aged?

Research Highlights: •Individuals with OA report greater health care utilization and coping efforts than healthy adults •Middle-aged participants report greater stress and role conflict •Middle-aged adults with osteoarthritis report more role limitations and health care utilization •Role perceptions and age are important in understanding the relationship of OA to health outcomesLittle is known about life course differences in social role participation among those with chronic diseases. This study examined role salience (i.e., importance), role limitations, and role satisfaction among middle- and older-aged adults with and without osteoarthritis (OA) and its relationship to depression, stress, role conflict, health care utilization and coping behaviours. Participants were middle- and older-aged adults with OA (n = 177) or no chronic disabling conditions (n = 193), aged ≥40 years. Respondents were recruited through community advertising and clinics in Ontario, Canada (2009-2010). They completed a 45-50 minute telephone interview and 20 minute self-administered questionnaire assessing demographics (e.g., age, gender); health (e.g., pain, functional limitations, health care utilization); the Social Role Participation Questionnaire (SRPQ) (role salience, limitations, satisfaction in 12 domains), and psychological variables (e.g., depression, stress, role conflict, behavioural coping). Analyses included two-way ANOVAs, correlations, and linear regression. Results indicated that middle-aged adults (40-59 years) reported greater role salience than older-aged adults (60+ years). Middle-aged adults with OA reported significantly greater role limitations and more health care utilization than all other groups. Middle-aged adults and those with OA also reported greater depression, stress, role conflict, and behavioural coping efforts than older adults or healthy controls. Controlling for age and OA, those with higher role salience and greater role limitations reported more health care utilization. Those with greater role limitations and lower role satisfaction reported greater depression, stress, role conflict, and behavioural coping. This study has implications for research and interventions, highlighting the need to characterize role participation as multidimensional. It points to the importance of taking into account the meaning of roles at different ages among those with chronic diseases like OA when developing interventions to help understand the impact of roles on psychological well-being.Canadian Institutes of Health Research(CIHR
