Are Men at High Risk for Osteoporosis Underscreened? A Quality Improvement ProjectSamta Jain, MD; Bilori Bilori, MD; Amit Gupta, MD; Perm J 2016 Winter;20(1):60-64 https://doi.org/10.7812/TPP/14-190AbstractContext: Osteoporosis is a major cause of morbidity and mortality in both men and women. The mortality rate in men within 1 year of hip fracture is 37.5%, which is 51% higher than in women. Although clear guidelines exist for osteoporosis screening in women, these are less clear for men. The available guidelines recommend screening high-risk men; however, screening does not appear to be a standard practice. IntroductionOsteoporosis is a major cause of morbidity and mortality in the form of fractures as a primary outcome, and later affecting quality of life. About 80,000 men sustain a hip fracture annually in the US.1 The rate of hip fractures in men living in residential care facilities is estimated to be 40%, and those who have broken a hip have a 20% chance of recurrence.2 The mortality rate in men in the first year after hip fracture is estimated to be up to 37.5%, which is 51% higher than in women.3,4 The annual burden of osteoporotic fractures in elderly individuals is estimated to cost between $12.2 and $17.9 billion, measured in 2002 US dollars, and this does not account for the loss of productivity of the patients and their caregivers.5 This financial burden is increasing as the US population ages. Osteoporosis in men seems to be an underdiagnosed and undertreated problem. Much is discussed about osteoporosis in women but not in men. The number of men with osteopenia (now called low bone mass) or osteoporosis is less than in women but is still substantial. Furthermore, the morbidity and mortality associated with osteoporosis in men is higher than in women.2,6,7 In men older than age 50, the likelihood of an osteoporotic fracture is more than the likelihood of developing prostate cancer.1 The exact number of men with osteoporosis is unclear at this time. However, it is estimated that about 2 million American men have osteoporosis and about 12 million men have low bone mass.1
The US Preventive Services Task Force does not recommend screening men routinely for osteoporosis but recognizes that there is an increasing burden of fractures in the aging male population.10 The Endocrine Society recommends testing higher-risk men, including men aged 70 years or older and men aged 50 to 69 years with secondary risk factors, using dual-energy x-ray absorptiometry (DXA).11 The International Society for Clinical Densitometry recommends bone mineral density screening in men age 70 years or older, and screening earlier if there is a fragility fracture or other known high-risk condition.12 In summary, high-risk men with a history of fracture or secondary causes of osteoporosis should be screened because benefits outweigh risks.10 After reviewing the guidelines for screening in high-risk men, we wanted to assess the existing standard of practice in a primary care setting at the Louis Stokes Cleveland Veterans Affairs (VA) Medical Center in Cleveland, OH. Anticipating low screening rates, we wanted to identify barriers to screening with the goal of improving standard of care. MethodsWe conducted a quality-improvement project as a part of the Transforming Outpatient Care curriculum in the Center of Excellence in Primary Care Education (COE-PCE) at the Louis Stokes Cleveland VA Medical Center. The COE-PCE is an Office of Academic Affiliations nationally funded, innovative training program for future health care professionals at 5 primary care outpatient clinic sites in the VA Medical Centers. As part of this project, we extracted data for all male veterans older than age 50 years who were enrolled with the 23 resident physicians and resident nurse practitioners’ primary care clinics between January 2003 and September 2013, using the Computerized Patient Record System, an electronic record system. We obtained the number of DXA scans performed in men older than age 50 years between January 2003 and November 2012. Subsequently, the charts were reviewed to identify the reasons why DXA scans were ordered in these men. It was found that men were screened because of a history of long-term steroid use, primary or secondary hypogonadism, liver cirrhosis, height loss, or a history of previous fracture or known low bone mass. Some uncommon indications were psoriatic arthropathy, primary or secondary hyperparathyroidism, and low body mass index (BMI). Because it was difficult to identify all the men who were appropriately screened and those who were not screened despite having risk factors, it was decided to use certain inclusion criteria, simply for the ease of data collection and analysis. These inclusion criteria were based on a brief review of the literature,13,14 which suggested that bone mineral density declines consistently in men age 50 years or older with any of the following risk factors: 1) steroid use of more than 5 mg/day for more than 3 months; 2) hypogonadism (testosterone level ≤ 2 ng/mL); and 3) systemic lupus, inflammatory bowel disease, rheumatoid arthritis, or sarcoidosis. We wanted to explore the barriers causing low screening rates. First, we analyzed the steps involved in the process of ordering DXA in the clinic. The process map in Figure 1 shows these steps. We thought of possible barriers at each step, including clinician-related factors and patient-related factors, on the basis of which we made a fishbone diagram (Figure 2). This fishbone diagram helped us devise the survey questionnaire. We then conducted online surveys to assess the level of existing awareness about osteoporosis in men and to assess the barriers for screening osteoporosis in high-risk men among nursing staff and resident physicians and nurse practitioners. We invited 23 residents and 10 nurses, who were enrolled with the COE-PCE curriculum and were involved with the care of these veterans, to participate in the surveys. Two surveys were performed about 5 months apart, in December 2012 and May 2013, respectively. We received 23 responses for the first survey and 16 for the second. Survey 1 included questions pertaining to whether screening for osteoporosis in men is important, who is at high risk, and so on (Figure 3). Survey 2 was devised to look for specific barriers in screening the high-risk men belonging to the 3 categories selected for this study (Figure 4). Survey 2 was analyzed separately for residents and nurses because the barriers for each of them were perceived to be different. On the basis of the survey results, our intervention to improve screening rates by 50% was mainly focused on educating the residents and nurses regarding the guidelines for screening and the impact of osteoporosis in men. A review of the literature and the available data regarding osteoporosis in men were presented to the residents on two occasions. The surveys themselves also served as an intervention to create awareness among the residents and nurses and provided them an opportunity to learn the screening guidelines. Data were then collected regarding the number of DXA scans performed, after creating awareness among the health care professionals. These data were collected at 2 different time points: the first set of data was collected after completion of 1 Plan-Do-Study-Act (PDSA) cycle (5 months from the first survey), referred to as Phase 1; and the second set, after another 5-month interval (Phase 2). The second set of data was to ensure continued improvement in the screening rate. ResultsChart ReviewA total of 854 male veterans over 50 years of age were enrolled in the residents’ clinic between January 2003 and November 2012, and 34 DXA scans were performed in these men during this period. By the criteria described in the Methods section, there were 105 men in the high-risk category, of whom only 11 men had undergone DXA scans for screening for osteoporosis. These data have been graphically represented in Figure 5. The baseline screening rate was found to be 10.4%. SurveySurvey 1 reflected that the residents and nurses were aware of the importance of screening high-risk men for osteoporosis with the appropriate screening tool. However, it was suggested that lack of clear guidelines posed a barrier, and the condition was perceived as low priority. Survey 2 obtained from physician and nurse practitioner residents revealed that the main reasons for not screening high-risk men for osteoporosis were its low priority (16%), insufficient time available for counseling patients (15%), absence of a reminder in the electronic medical record (15%), unclear guidelines (14%), and lack of comfort in counseling the patients (13%). The survey from nurses revealed absence of a reminder in electronic medical records (20%), unclear guidelines (16%), and lack of comfort in counseling the patients (10%) as the major limiting factors. The total number of DXA at the end of Phase 1 had increased compared with the baseline screening data. In April 2013, a total of 32 DXA scans were performed for a high-risk population of 202 (16.8% compared with 11% at baseline). This number further increased over the next 5 months: 59 DXA scans in 284 high-risk men, resulting in a screening rate of 20.7%. These results are graphically depicted in Figures 6 to 8. Thus, there was a positive trend toward screening high-risk men. Hence, we met our goal to improve osteoporosis screening rates in high-risk men by at least 50% (from 10.4% to 20.7%) in a 10-month period. Interestingly, we found that an increasing number of men were tested for hypogonadism with testosterone levels. It is unclear what factors led to this. The increased general awareness of tests available for erectile dysfunction, andropause, and fatigue in elderly men could have contributed. In fact, the number of DXA scans ordered in men with hypogonadism increased from 9% in Phase 1 to 24% in Phase 2. DiscussionNo clear guidelines are available for screening men for osteoporosis, but it is clear that fractures in men lead to substantial mortality and morbidity, increased number of hospitalizations, and thereby increasing health care costs. Our data analysis suggests osteoporosis screening rates in men are low at our VA primary care resident trainee clinics mainly because of lack of awareness. We successfully improved the screening rate by creating awareness among residents and nurses. Readily available data through the electronic medical record system and a multidisciplinary team approach helped the project. Our project has a few limitations. The number of subjects in the data analysis is small. Also, the follow-up period was short; therefore, it cannot be determined whether the effects of the intervention are sustainable over a longer time. We suspect that for continued benefits of this intervention, we would have to conduct educational sessions regularly. This will not only educate the new residents and nurses but will also keep reminding the existing health care professionals of the importance of screening. The challenging aspects of increased screening would be an increased workload for the clinicians to counsel patients regarding the need for screening, to interpret the results, and to diagnose, to treat, and to monitor the patients, as well as increased burden on the Radiology Department to scan these men and scheduling issues. From the patients’ perspective, this may be anxiety provoking and may add to the burden of medications with calcium supplements or bisphosphonates. Bisphosphonates have been recommended for treatment of osteoporosis in men with hypogonadism, along with testosterone replacement.15 Not many studies have been done to look at the cost-effectiveness of DXA to detect osteoporosis in men, followed by its treatment. Schousboe et al16 found that bone densitometry followed by bisphosphonate therapy may be cost-effective for osteoporotic men older than age 65 years with a history of fracture, and for men over 80 years with no history of fracture. The cost-effectiveness of this strategy in younger high-risk men has not been evaluated, although Schousboe et al16 have suggested that it may be beneficial for men as young as 70 years of age. ConclusionIn the future, more studies are required to look at the cost-effectiveness of screening younger high-risk men with DXA, followed by therapy with bisphosphonates and/or androgen replacement. It would be important to include risk stratification questions in the history and physical examination during the office interview to screen high-risk men. It would possibly be beneficial to use a tool such as the FRAX (Fracture Risk Assessment) calculator to detect men at higher risk of fragility fractures.17 Disclosure StatementThe author(s) have no conflicts of interest to disclose.
