RESUMO
OBJECTIVE: To determine frequency that ED visits are needed, and the most common chief complaints and medications prescribed to Veterans with spinal cord injuries and disorders (SCI/D). METHODS: The Veterans Health Administration (VHA) SCI and Disorders (SCI/D) Registry (VHA SCIDR) was used to identify Veterans with SCI/D over a five-year period (fiscal years 2018-2022). The primary outcome was the proportion of Veterans with SCI/D who had visits to the ED during the study period. Secondary outcomes included diagnostic codes and medications prescribed in the ED, and other healthcare encounters. RESULTS: Overall, 18,464 Veterans with SCI/D, including 80,661 patient-years were included. Of these Veterans, 10,234 (55.4%) had at least one ED visit and 8230 (44.6%) did not. ED visits were consistent, ranging from 33.5% to 36.4% annually. The number of in-person healthcare encounters decreased over the study period. The most common ED diagnostic codes were paraplegia or quadriplegia, discharge counseling, UTI, neuromuscular dysfunction of the bladder and low back pain. The most common medications prescribed in the ED were analgesics (e.g., acetaminophen, ketorolac), antimicrobials (e.g., ceftriaxone, vancomycin) and ondansetron. Antibiotics were among the most prescribed discharge medications, including ciprofloxacin, sulfamethoxazole/trimethoprim, cephalexin, and doxycycline. CONCLUSION: This national study of Veterans with SCI/D characterized ED healthcare utilization. Overall, more than half of Veterans with SCI/D required an ED visit during the five-year study period and over one third of Veterans in each fiscal year required an ED visit. Interventions to target prevention of ED visits and subsequent hospitalizations could focus on these areas.
RESUMO
BACKGROUND: Elective endovascular repair of an abdominal aortic aneurysm results in lower perioperative mortality than traditional open repair, but after 4 years this survival advantage is not seen; in addition, results of two European trials have shown worse long-term outcomes with endovascular repair than with open repair. Long-term results of a study we conducted more than a decade ago to compare endovascular repair with open repair are unknown. METHODS: We randomly assigned patients with asymptomatic abdominal aortic aneurysms to either endovascular repair or open repair of the aneurysm. All the patients were candidates for either procedure. Patients were followed for up to 14 years. RESULTS: A total of 881 patients underwent randomization: 444 were assigned to endovascular repair and 437 to open repair. The primary outcome was all-cause mortality. A total of 302 patients (68.0%) in the endovascular-repair group and 306 (70.0%) in the open-repair group died (hazard ratio, 0.96; 95% confidence interval [CI], 0.82 to 1.13). During the first 4 years of follow-up, overall survival appeared to be higher with endovascular repair than with open repair; from year 4 through year 8, overall survival was higher in the open-repair group; and after 8 years, overall survival was once again higher in the endovascular-repair group (hazard ratio for death, 0.94; 95% CI, 0.74 to 1.18). None of these trends were significant. There were 12 aneurysm-related deaths (2.7%) in the endovascular-repair group and 16 (3.7%) in the open-repair group (between-group difference, -1.0 percentage point; 95% CI, -3.3 to 1.4); most deaths occurred during the perioperative period. Aneurysm rupture occurred in 7 patients (1.6%) in the endovascular-repair group, and rupture of a thoracic aneurysm occurred in 1 patient (0.2%) in the open-repair group (between-group difference, 1.3 percentage points; 95% CI, 0.1 to 2.6). Death from chronic obstructive lung disease was just over 50% more common with open repair (5.4% of patients in the endovascular-repair group and 8.2% in the open-repair group died from chronic obstructive lung disease; between-group difference, -2.8 percentage points; 95% CI, -6.2 to 0.5). More patients in the endovascular-repair group underwent secondary procedures. CONCLUSIONS: Long-term overall survival was similar among patients who underwent endovascular repair and those who underwent open repair. A difference between groups was noted in the number of patients who underwent secondary therapeutic procedures. Our results were not consistent with the findings of worse performance of endovascular repair with respect to long-term survival that was seen in the two European trials.

BACKGROUND: Provisions of the Affordable Care Act (ACA) provided nonelderly individuals, including Veterans, with additional health care coverage options. This may impact enrollment for health care through the Veterans Health Administration (VHA). National enrollment data was used to: (1) compare characteristics of enrollees at 3 time points in relation to the implementation of ACA insurance provisions (2012); and (2) examine enrollment trends. METHODS: The study population included a 10% sample of Veterans under age 65 who were VHA enrollees between January 2012 and September 2015. Demographic and baseline characteristics were compared between 3 enrollment groups: pre-2012, pre-ACA (2012-2013), and post-ACA (2014-2015). Using an interrupted time series approach, we employed pooled logistic regression to assess trends in new VHA enrollment, overall, and by select enrollee characteristics. RESULTS: A total of 429,833 enrollees were identified. Compared with pre-ACA enrollees, post-ACA enrollees were more likely to be older, have a service-connected disability, live further away from a VHA medical center, but less likely to use primary care within 6 months. The post-ACA quarterly trend in the odds of being a new enrollee was 3% lower (95% confidence interval: 0.96, 0.98) as compared with the pre-ACA trend. This decline was consistent across sex, geography, (all but 1) priority group, and state Medicaid-expansion subgroups. CONCLUSIONS: The ACA appears to have contributed to a decline in new VHA enrollment. In addition, the profile of newer enrollees differs from that of pre-ACA enrollees. The VHA must continue to monitor trends in demand in order to continue delivering high-quality, efficient care.

OBJECTIVE: Deep brain stimulation has been shown to have a significant long-term beneficial effect on motor function. However, whether it affects survival is not clear. In this study, we compared survival rates for Parkinson's disease (PD) patients who underwent deep brain stimulation (DBS) with those who were medically managed. METHODS: A retrospective analysis of Veterans Affairs and Medicare administrative data of veterans with PD who received DBS and were propensity score matched to a cohort of veterans with PD who did not receive DBS between 2007-2013. RESULTS: Veterans with PD who received DBS had a longer survival measured in days than a matched group of veterans who did not undergo DBS (mean = 2291.1 [standard error = 46.4] days [6.3 years] vs 2063.8 [standard error = 47.7] days [5.7 years]; P = .006; hazard ratio = 0.69 [95% confidence interval 0.56-0.85]). Mean age at death was similar for both groups (76.5 [standard deviation = 7.2] vs 75.9 [standard deviation = 8.4] years, P = .67), respectively, and the most common cause of death was PD. CONCLUSIONS: DBS is associated with a modest survival advantage when compared with a matched group of patients who did not undergo DBS. Whether the survival advantage reflects a moderating influence of DBS on PD or on comorbidities that might shorten life or whether differences may be a result of unmeasured differences between groups is not known. © 2017 International Parkinson and Movement Disorder Society.

OBJECTIVES: Pain is the most prevalent problem among veterans, who receive pain diagnoses 5 times more frequently than the general population. Opioids are commonly prescribed for pain, but they have potential for misuse and serious adverse events. The study objective was to evaluate opioid dispensing patterns and predictors for overlap in veterans who are eligible for Medicare Part D benefits. METHODS: A sample of male and all female veterans aged 66 years and older without cancer in 2005-2009 was included. Overlapping days' supply of opioids were evaluated within the U.S. Department of Veterans Affairs (VA), within Part D, and in cross-system users of VA and Part D-reimbursed pharmacies during 2007-2009. Dispensing patterns were analyzed with t tests and chi-square tests. Predictors of overlap were identified with general estimating equations. RESULTS: At least 1 opioid was dispensed to 88.5% of the sample. In 2006 after Part D implementation, 55.2% of opioids were dispensed by VA, decreasing to 44.3% in 2009 (P <0.0001). Opioids dispensed from Part D-reimbursed pharmacies had a higher frequency of overlap compared to those filled at a VA facility (P <0.0001). While overlapping days' supply for opioids filled at VA decreased, overlap increased for prescriptions filled at Part D-reimbursed pharmacies (P <0.0001). There was minimal overlap in opioids between systems, but cross-system use increased over the study period. Predictors for overlap include females, Part D enrollment, no VA medication copay, sleep disorders, psychiatric diagnoses, and substance or alcohol abuse (all P <0.01). Veterans who were Hispanic, older, and had higher incomes had lower overlap odds (all P <0.0001). CONCLUSIONS: Opioids dispensed from Part D-reimbursed pharmacies had a higher frequency of overlapping days' supply as compared to those filled by the VA, but there was minimal overlap between systems. While overlapping opioid prescriptions filled by the VA decreased from 2007 to 2009, overlap increased for prescriptions filled at Part D-reimbursed pharmacies. Tools, such as drug monitoring programs, should be used by VA and non-VA providers to decrease opioid-related harms and misuse.

BACKGROUND: Predialysis nephrology care is associated with lower mortality and rates of hospitalization following chronic dialysis initiation. Whether more frequent predialysis nephrology care is associated with other favorable outcomes for older adults is not known. METHODS: Retrospective cohort study of patients ≥66 years who initiated chronic dialysis in 2000-2001 and were eligible for VA and/or Medicare-covered services. Nephrology visits in VA and/or Medicare during the 12-month predialysis period were identified and classified by low intensity (<3 visits), moderate intensity (3-6 visits), and high intensity (>6 visits). Outcome measures included very low estimated glomerular filtration rate, severe anemia, use of peritoneal dialysis, and receipt of permanent vascular access at dialysis initiation and death and kidney transplantation within two years of initiation. Generalized linear models with propensity score weighting were used to examine the association between nephrology care and outcomes. RESULTS: Among 58,014 patients, 46 % had none, 22 % had low, 13 % had moderate, and 19 % had high intensity predialysis nephrology care. Patients with a greater intensity of predialysis nephrology care had more favorable outcomes (all p < 0.001). In adjusted models, patients with high intensity predialysis nephrology care were less likely to have severe anemia (RR = 0.70, 99 % CI: 0.65-0.74) and more likely to have permanent vascular access (RR = 3.60, 99 % CI: 3.42-3.79) at dialysis initiation, and less likely to die within two years of dialysis initiation (RR = 0.80, 99 % CI: 0.77-0.82). CONCLUSION: In a large cohort of older adults treated with chronic dialysis, greater intensity of predialysis nephrology care was associated with more favorable outcomes.

Background: Osteoporotic fractures occur in almost half of patients with a spinal cord injury (SCI) and are associated with significant morbidity and excess mortality. Paralyzed Veterans Administration (PVA) guidelines suggest that adequate calcium and vitamin D intake is important for skeletal health, however, the association of these supplements with osteoporotic fracture risk is unclear. Objectives: To determine the association of filled prescriptions for calcium and vitamin D with fracture risk in Veterans with an SCI. Methods: The 5897 persons with a traumatic SCI of at least 2 years' duration (96% male; 4% female) included in the VSSC SCI/D Registry in FY2014 were followed from FY2014 to FY2020 for incident upper and lower extremity fractures. Filled daily prescriptions for calcium or vitamin D supplements for ≥6 months with an adherence ≥80% were examined. Results: Filled prescriptions for calcium (hazard ratio [HR] 0.65; 95% CI, 0.54-0.78) and vitamin D (HR 0.33; 95% CI, 0.29-0.38) supplements were associated with a significantly decreased risk for incident fractures. Conclusion: Calcium and vitamin D supplements are associated with decreased risk of fracture, supporting PVA guidelines that calcium and vitamin D intake are important for skeletal health in persons with an SCI.

The Veterans Affairs (VA) medical centers provide care for millions of Veterans at high risk of cardiovascular disease and accurate BP measurement in this population is vital for optimal BP control. Few studies have examined terminal digit preference (TDP), a marker of BP measurement bias, clinician perceptions of BP measurement, and BP control in VA medical centers. This mixed methods study examined BP measurements from Veterans aged 18 to 85 years with hypertension and a primary care visit within 8 VA medical centers. TDP for all clinic BP measurements was examined using a goodness of fit test assuming 10% frequency for each digit. Interviews were also conducted with clinicians from 3 VA medical centers to assess perceptions of BP measurement. The mean age of the 98,433 Veterans (93% male) was 68.5 years (SD 12.7). BP was controlled (<140/90 mmHg) in 76.5% and control rates ranged from 72.2% to 81.0% across the 8 VA medical centers. Frequency of terminal digits 0 through 9 differed significantly from 10% for both SBP and DBP within each center (P < .001) but level of TDP differed by center. The highest BP control rates were noted in centers with highest TDP for digits 0 and 8 for both SBP and DBP. Clinicians reported use of semi-automated oscillometric devices for clinic BP measurement, but elevated BP readings were often confirmed by auscultatory methods. Significant TDP exists for BP measurement in VA medical centers, which reflects continued use of auscultatory methods.

BACKGROUND: Healthcare for end-stage renal disease (ESRD) is intensive, expensive, and provided in both the public and private sector. Using a societal perspective, we examined healthcare costs and health outcomes for Department of Veterans Affairs (VA) ESRD patients comparing those who received hemodialysis care at VA versus private sector facilities. METHODS: Dialysis patients were recruited from 8 VA medical centers from 2001 through 2003 and followed for 12 months in a prospective cohort study. Patient demographics, clinical characteristics, quality of life, healthcare use, and cost data were collected. Healthcare data included utilization (VA), claims (Medicare), and patient self-report. Costs included VA calculated costs, Medicare dialysis facility reports and reimbursement rates, and patient self-report. Multivariable regression was used to compare costs between patients receiving dialysis at VA versus private sector facilities. RESULTS: The cohort comprised 334 patients: 170 patients in the VA dialysis group and 164 patients in the private sector group. The VA dialysis group had more comorbidities at baseline, outpatient and emergency visits, prescriptions, and longer hospital stays; they also had more conservative anemia management and lower baseline urea reduction ratio (67% vs. 72%; P<0.001), although levels were consistent with guidelines (Kt/V≥1.2). In adjusted analysis, the VA dialysis group had $36,431 higher costs than those in the private sector dialysis group (P<0.001). CONCLUSIONS: Continued research addressing costs and effectiveness of care across public and private sector settings is critical in informing health policy options for patients with complex chronic illnesses such as ESRD.

BACKGROUND AND OBJECTIVES: Chronic kidney disease (CKD) and spinal cord injury and disorders (SCI/D) are common and costly conditions among Veterans. However, little is known about CKD among adults with SCI/D. METHODS: We conducted cross-sectional analyses of Veterans with SCI/D across all VA facilities in 2006. CKD was defined as an estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2) and categorized by standard eGFR strata. eGFR was calculated in two ways: (a) the Modification of Diet in Renal Disease (MDRD) equation and (b) the MDRD equation + an empirically derived correction factor for SCI/D (MDRD-SCI/D). Logistic regression models were used to examine the relationship between patient characteristics and CKD. RESULTS: Among 9,333 SCI/D Veterans with an available eGFR, the proportion with CKD was substantially higher based on the MDRD-SCI/D equation (35.2%) than based on the MDRD equation (10.2%). In adjusted analyses, while older age (OR for >65 years = 2.53; 95% CI: 2.21-2.89), female sex (OR 2.18; 95% CI: 1.62-2.92), and a non-traumatic cause for injury (OR 1.39; 95% CI: 1.23-1.57) were associated with an increased odds of CKD, black race (OR 0.64; 95% CI: 0.56-0.72) and a duration of injury of ≥10 years (OR 0.76; 95% CI: 0.67-0.86) were associated with a decreased odds of CKD. Diagnostic codes for CKD and nephrology visits were infrequent for SCI/D Veterans with CKD (27.51 and 6.58%, respectively). CONCLUSION: Using a recently validated version of the MDRD equation with a correction factor for SCI/D, over 1 in 3 Veterans with SCI/D had CKD, which is more than 3-fold higher than when traditional MDRD estimation is used.

Reasons for acquiring insurance outside Department of Veterans Affairs (VA) health care coverage among VA enrollees are incompletely understood. To assess Veterans' decision-making and acquisition of non-VA health care insurance in the Affordable Care Act era, we used mailed questionnaires and semistructured interviews in a stratified random sample of VA enrollees <65 years in the Midwest. Of the 3,666 survey participants, 32.1% reported non-VA insurance. Frequently reported reasons included wanting coverage for emergency situations or family members. Those without non-VA insurance cited unaffordability as the main obstacle. Analysis of the semistructured interview data revealed similar findings. In multivariable logistic regression analyses, characteristics associated with non-VA insurance included higher income (>$50,000 vs. <$10,000, odds ratio [OR] = 5.95, 95% confidence interval [CI]: 3.45-10.3, p < .001). As financial barriers exist for acquisition of non-VA insurance and hence community care, it is critically important that VA enrollees' health care needs are met through VA or community providers financed through VA.

BACKGROUND: Access to nephrology care before initiation of chronic dialysis is associated with improved outcomes after initiation. Less is known about the effect of predialysis nephrology care on healthcare costs and utilization. METHODS: We conducted retrospective analyses of elderly patients who initiated dialysis between January 1, 2000 and December 31, 2001 and were eligible for services covered by the Department of Veterans Affairs. We used multivariable generalized linear models to compare healthcare costs for patients who received no predialysis nephrology care during the year before dialysis initiation with those who received low- (1-3 nephrology visits), moderate- (4-6 visits), and high-intensity (>6 visits) nephrology care during this time period. RESULTS: There were 8022 patients meeting inclusion criteria: 37% received no predialysis nephrology care, while 24% received low, 16% moderate, and 23% high-intensity predialysis nephrology care. During the year after dialysis initiation, patients in these groups spent an average of 52, 40, 31, and 27 days in the hospital (P < 0.001), respectively, and accounted for an average of $103,772, $96,390, $93,336, and $89,961 in total healthcare costs (P < 0.001), respectively. Greater intensity of predialysis nephrology care was associated with lower costs even among patients whose first predialysis nephrology visit was ≤ 3 months before dialysis initiation. Patients with greater predialysis nephrology care also had lower mortality rates during the year after dialysis initiation (43%, 38%, 28%, and 25%, respectively, P < 0.001). CONCLUSIONS: Greater intensity of predialysis nephrology care was associated with fewer hospital days and lower total healthcare costs during the year after dialysis initiation, even though patients survived longer.

BACKGROUND: The availability of Medicare Part D pharmacy coverage may increase veterans' options for obtaining medications outside of the Department of Veterans Affairs (VA) pharmacies. However, availability of Part D coverage raises the potential that veterans may be receiving similar medications from VA and non-VA pharmacies. The VA's personal health record portal, My HealtheVet, allows veterans to self-enter the non-VA medications that they obtained from community-based pharmacies, including those reimbursed by Medicare Part D. The Blue Button medication view feature of My HealtheVet allows veterans to view and download their VA and self-entered non-VA medication history. OBJECTIVE: To examine whether the use by veterans of the Blue Button feature of My HealtheVet was associated with less acquisition of similar medications from VA and community-based pharmacies reimbursed by Medicare Part D. METHODS: This study included a national sample of veterans who were new My HealtheVet users during fiscal year 2013 (October 1, 2012-September 30, 2013) and who used the Blue Button medication view feature of My HealtheVet at least once (users). We compared these veterans with a random sample of veterans who were not registered to use My HealtheVet (nonusers). From these groups, we identified veterans who were enrolled in Part D. We used multiple logistic regression analysis to assess the association of Blue Button medication view use with obtaining medications from the same drug classes (with overlap of 7 or more days) from VA and Part D-reimbursed pharmacies. RESULTS: There were 7,973 My HealtheVet medication view users and 65,985 nonusers. During a 12-month period, medication view users received more 30-day supplies of medications (one 90-day supply equals three 30-day supplies) than nonusers, on average (152.1 vs 71.3, P < 0.001). A larger percentage of users than nonusers obtained medications from VA and Part D-reimbursed pharmacies with overlapping days supply from the same drug classes (30% vs 23%, P < 0.001). However, for veterans who obtained greater numbers of 30-day supplies (82 or more), a significantly smaller percentage of users than nonusers obtained overlapping medications from VA and Part D-reimbursed pharmacies. Moreover, controlling for the total number of 30-day supplies that veterans received, the odds of obtaining medications from VA and Part D-reimbursed pharmacies with days supply that overlapped by at least 7 days for the same drug classes was 18% lower for users than nonusers (P=0.002). CONCLUSIONS: Veterans who used the Blue Button medication view feature of My HealtheVet obtained a larger number of 30-day supplies of medications from VA pharmacies than nonusers. For veterans who obtained a larger number of 30-day supplies of medications, use of the Blue Button medication view feature of My HealtheVet was associated with less overlap in days supply of medication from the same drug class from VA and Part D-reimbursed pharmacies.

OBJECTIVE: To compare the complications, healthcare utilization and costs following DBS or medical management for patients with Parkinson's disease (PD). METHODS: We examined healthcare utilization and costs for up to 5 years between veterans with DBS and those with medical management for PD. Veterans who received DBS between 2007 and 2013 were matched with veterans who received medical management using propensity score approaches. Healthcare utilization and costs were obtained from national VA and Medicare data sources and compared using procedures to adjust for potential differences in length of follow-up. RESULTS: We identified 611 veterans who had received DBS and a matched group of 611 veterans who did not undergo DBS. Among DBS patients, 59% had the electrodes and generator implanted during separate admissions. After 5 years of follow-up, average total healthcare costs, including DBS procedures and complications, were $77,131 (95% confidence interval: $66,095-$88,168; P < 0.001) higher per person for patients who received DBS ($162,489) than patients who received medical management ($85,358). In contrast, excluding the costs of the DBS procedures and complications, average total costs were not significantly different between patients who received DBS and patients who received medical management after 5 years of follow-up. CONCLUSIONS: Healthcare costs over 5 years were higher for veterans who received DBS. These higher healthcare costs may reflect the costs of DBS procedures and any follow-up required plus greater surveillance by healthcare professionals following DBS as well as unobserved differences in the patients who received medical management or DBS.
RESUMO
BACKGROUND: Both reduced glomerular filtration rate and increased urine albumin excretion, markers of chronic kidney disease (CKD), are associated with increased risk of atherosclerotic cardiovascular disease (ASCVD). However, CKD is not recognized as an ASCVD risk equivalent by most lipid guidelines. Statin medications, especially when combined with ezetimibe, significantly reduce ASCVD risk in patients with nondialysis-dependent CKD. Unless physicians recognize the heightened ASCVD risk in this population, statins may not be prescribed in the absence of clinical cardiovascular disease or diabetes, a recognized ASCVD risk equivalent. We examined statin use in adults with nondialysis-dependent CKD and examined whether the use differed in the presence of clinical ASCVD and diabetes. METHODS: This study ascertained statin use from pharmacy dispensing records during fiscal years 2012 and 2013 from the US Department of Veterans Affairs Healthcare System. The study included 581 344 veterans aged ≥50 years with nondialysis-dependent CKD Stages 3-5 with no history of kidney transplantation or dialysis. The 10-year predicted ASCVD risk was calculated with the pooled risk equation. RESULTS: Of veterans with CKD, 62.1% used statins in 2012 and 55.4% used statins continuously over 2 years (2012-13). Statin use in 2012 was 76.2 and 75.5% among veterans with CKD and ASCVD or diabetes, respectively, but in the absence of ASCVD, diabetes or a diagnosis of hyperlipidemia, statin use was 21.8% (P < 0.001). The 10-year predicted ASCVD risk was ≥7.5% in 95.1% of veterans with CKD, regardless of diabetes status. CONCLUSIONS: Statin use is low in veterans with nondialysis-dependent CKD in the absence of ASCVD or diabetes despite high-predicted ASCVD risk. Future studies should examine other populations.
RESUMO
INTRODUCTION: The benefits of statin medications in patients receiving maintenance dialysis remains controversial and clinical trials overall have shown no benefit. Potential side effects of statin medications include myalgias, myopathy, and memory loss and risk of side effects associated with statin medications increase with higher statin doses. We examined statin use and statin dose among Veterans with dialysis dependent CKD. Such information may help clinicians modulate medication use and reduce pill burden in appropriate patients. METHODS: This cross-sectional analysis ascertained medication utilization by linking records from the U.S. Department of Veteran's Affairs (VA) Managerial Cost Accounting Pharmacy National Data Extracts and Medicare Part D during calendar year 2013 for Veterans with dialysis-dependent CKD enrolled in and/or using VA healthcare. The venue of dialysis and patient characteristics were ascertained by linking VA Medical SAS datasets, VA Fee Basis datasets (for non-VA care paid for by VA), Medicare claims and the United States Renal Data Systems patient core files. FINDINGS: We identified 18,494 Veterans with dialysis-dependent CKD who were enrolled in and/or used VA healthcare, had no history of kidney transplantation, and were alive on January 1, 2014. More than half (58.1%) of Veterans with dialysis-dependent CKD used statins and 35.7% of statin utilization was high dose. Statins were the third most commonly prescribed medication after beta blockers (64.8%) and phosphate binders (64.5%). DISCUSSION: Statins are a commonly prescribed medication among Veterans receiving maintenance dialysis and approximately one-third of statin utilization is high dose in this population. Future studies should examine patient preferences, comorbidities, and dialysis characteristics that impact the risks and benefits of statin use in order to identify those patients who will or will not benefit from continued statin use.

OBJECTIVES: To compare characteristics, health conditions, and medication acquisition patterns by fee-for-service (FFS) or Medicare Advantage (MA) plan enrollment status for Medicare-eligible veterans. STUDY DESIGN: Retrospective analysis of all female and a random 10% sample of male veterans. METHODS: Data were derived from the US Department of Veterans Affairs (VA) and Medicare administrative databases. Demographic, geographic, and RxRisk-V risk classes were ascertained in 2008. Medicare Part D enrollment, medication acquisition, and use of high-risk medications (HRMs) were examined in 2009. A veteran was classified as an MA enrollee if he or she was enrolled in an MA plan for at least 1 month in 2008-2009. Descriptive and regression analyses were conducted to compare veterans' characteristics and medication acquisition patterns by plan enrollment type controlling for veterans' characteristics. RESULTS: Veterans who resided in urban settings and in the West or Northeast and who had co-payments for their VA medications had greater odds of enrolling in MA programs compared with their counterparts. MA-enrolled veterans were more likely to be dual (32.3% vs 7.0%) or Medicare-reimbursed (31.1% vs 14.5%) pharmacy users and less likely to be VA-only pharmacy users (29.4% vs 48.7%) than FFS enrollees. Higher proportions of MA-enrolled veterans received HRMs compared with those in the FFS sector (17.0% vs 14.3%). CONCLUSIONS: Providers both inside and outside of the VA should consider that substantial information about the medication use of veterans may be unavailable in their healthcare systems' electronic records.

We examined associations between enrollment in Medicare Part D pharmacy benefits and changes in medication acquisition from Department of Veterans Affairs (VA) pharmacies. We included all women and a random 10% sample of men who were VA enrollees, ≥65 years old as of January 1, 2004, and alive through December 2007. We used difference-in-differences models with propensity score weighting to examine changes in medication acquisition between 2005 (before Part D was implemented) and 2007 (after Part D implementation) for veterans who were or were not Part D enrolled. Of 231,716 veterans meeting inclusion criteria, 49,881 (21.5%) were enrolled. While 30-day medication supplies decreased from 26.2 to 23.4 for enrolled veterans, they increased from 36.6 to 37.4 for nonenrolled veterans (difference-in-differences: -4.0, p < .001). Reductions in 30-day supplies were greater among veterans who were required to pay VA copayments for some or all medications and who used VA and Medicare outpatient services.

AIMS: To examine the relationship between systolic blood pressure (SBP) variability and the risk of microvascular complications in a non-elderly diabetic population. METHODS: This is a retrospective cohort study of individuals aged ≤60years treated for diabetes in 2003 in the US Department of Veterans Affairs healthcare system. Individuals were followed for five years for any new diagnosis of diabetic nephropathy, retinopathy, or neuropathy. In each year of follow-up, individuals were classified into quartiles based on their SBP variability. RESULTS: We identified 208,338 patients with diabetes without diabetic nephropathy, retinopathy, or neuropathy at baseline. Compared to individuals with the least SBP variability (Quartile 1), those with most variability (Quartile 4) had 81% (OR=1.81; 95% CI, 1.72-1.91), 17% (OR=1.17; 95% CI, 1.13-1.21), 30% (OR=1.30; 95% CI, 1.25-1.35), and 19% (OR=1.19; 95% CI, 1.15-1.23) higher incidence of nephropathy, retinopathy, neuropathy, and any complication, respectively, after adjusting for mean SBP, demographic and clinical factors. CONCLUSIONS: We found a significant graded relationship between SBP variability and the incidence of each complication and of any combined endpoint. This is the first study showing a significant association between SBP variability and the risk of diabetic retinopathy and neuropathy.

PURPOSE: The patterns of medication acquisition for veterans dually eligible for pharmacy benefits from the Department of Veterans Affairs (VA) and Medicare Part D-reimbursed pharmacies were examined. METHODS: The characteristics of veterans who used pharmacies reimbursed by (1) VA only, (2) both VA and Part D-reimbursed, and (3) Part D-reimbursed only pharmacies in 2009 were compared and their medication types and sources examined. Pharmacy usage was measured as the number of 30-day medication supplies and the number of different drug classes that veterans received from VA and Part D-reimbursed pharmacies. Chi-square testing and analysis of variance were used to compare unadjusted patient characteristics and healthcare utilization. RESULTS: A total of 145,899 veterans with any VA or Part D-reimbursed pharmacy use were included in the study: 69.6% used VA pharmacies only, 9.9% used VA and Part D-reimbursed pharmacies, and 20.5% used Part D-reimbursed pharmacies only. Veterans who lived in rural areas, were non-Black, had VA medication copayments, or were dual or Medicare-only outpatient users were more likely to be dual or Part D-reimbursed only pharmacy users (p < 0.001). Dual pharmacy users received more 30-day supplies than did the other two pharmacy-use groups (p < 0.001). CONCLUSION: Nearly one third of VA users received medications from Part D-reimbursed pharmacies, either alone or together with VA pharmacies. Among dual pharmacy users, over half received medications from the same drug class from both VA and Part D-reimbursed pharmacies for which the days' supplies overlapped by more than seven days.
