Methods

This study was a retrospective chart analysis using descriptive statistics. It was reviewed and approved by the institutional review board at Captain James A. Lovell Federal Health Care Center (FHCC). Patients were included in the study if they were enrolled in the HBPC program at FHCC. Patients were excluded if they were receiving hospice or palliative care, had a limited life expectancy per the HBPC provider, or had a diagnosis of osteoporosis that was being managed by a VA endocrinologist, rheumatologist, or non-VA provider.

The study was conducted from February 1, 2018, through November 30, 2018. All chart reviews were done through the FHCC electronic health record. A minimum of 80 and maximum of 150 charts were reviewed as this was the typical patient volume in the HBPC program. Basic demographic information was collected and analyzed by calculating FRAX and OST scores. With the results, patients were classified as low or high risk of developing osteoporosis, and whether a DEXA scan should be recommended.

Results

After chart review, 83 patients were enrolled in the FHCC HBPC program during the study period. Out of these, 5 patients were excluded due to hospice or palliative care status, limited life expectancy, or had their osteoporosis managed by another non-HBPC provider. As a result, 78 patients were analyzed to determine their risk of osteoporosis (Figure 2). Most of the patients were white males with a median age of 82 years. A majority of the patients did not have any current or previous treatment with bisphosphonates, 77% had normal vitamin D levels, and only 13% (10) were current smokers; of the male patients only 21% (15) had a previous DEXA scan (Table 3).

The FRAX and OST scores for each male patient were calculated (Table 4). Half the patients were low risk for osteoporosis. Just 20% (14) of the patients were at high risk for osteoporosis, and only 6 of those had DEXA scans. However, if expanding the criteria to OST scores of < 2, then only 24% (10) received DEXA scans. When calculating FRAX scores, 30% (21) had ≥ 9.3% for major osteoporotic fracture risk, and only 19% (4) had received a DEXA scan.

Discussion

Based on the collected data, many of the male HBPC patients have not had an evaluation for osteoporosis despite being in a high-risk population and meeting some of the screening guidelines by various organizations.1 Based on Diem and colleagues and the 2007 VA report, utilizing OST scores could help capture a subset of patients that would be referred for DEXA scans.5,12 Of the 60% (42) of patients that met OST scores of < 2, 76% (32) of them could have been referred for DEXA scans for osteoporosis evaluation. However, at the time of publication of this article, 50% (16) of the patients have been discharged from the service without interventions. Of the remaining 16 patients, only 2 were referred for a DEXA scan, and 1 patient had confirmed osteoporosis. Currently, these results have been reviewed by the HBPC provider, and plans are in place for DEXA scan referrals for the remaining patients. In addition, for new patients admitted to the program and during annual reviews, the plan is to use OST scores to help screen for osteoporosis.
