Type 2 Diabetes Management, Control and Outcomes During the COVID-19 Pandemic in Older US Veterans: an Observational Study.

BACKGROUND: The COVID-19 pandemic required a change in outpatient care delivery models, including shifting from in-person to virtual visits, which may have impacted care of vulnerable patients. OBJECTIVE: To describe the changes in management, control, and outcomes in older people with type 2 diabetes (T2D) associated with the shift from in-person to virtual visits. DESIGN AND PARTICIPANTS: In veterans aged ≥ 65 years with T2D, we assessed the rates of visits (in person, virtual), A1c measurements, antidiabetic deintensification/intensification, ER visits and hospitalizations (for hypoglycemia, hyperglycemia, other causes), and A1c level, in March 2020 and April-November 2020 (pandemic period). We used negative binomial regression to assess change over time (reference: pre-pandemic period, July 2018 to February 2020), by baseline Charlson Comorbidity Index (CCI; > 2 vs. <= 2) and A1c level. KEY RESULTS: Among 740,602 veterans (mean age 74.2 [SD 6.6] years), there were 55% (95% CI 52-58%) fewer in-person visits, 821% (95% CI 793-856%) more virtual visits, 6% (95% CI 1-11%) fewer A1c measurements, and 14% (95% CI 10-17%) more treatment intensification during the pandemic, relative to baseline. Patients with CCI > 2 had a 14% (95% CI 12-16%) smaller relative increase in virtual visits than those with CCI <= 2. We observed a seasonality of A1c level and treatment modification, but no association of either with the pandemic. After a decrease at the beginning of the pandemic, there was a rebound in other-cause (but not hypo- and hyperglycemia-related) ER visits and hospitalizations from June to November 2020. CONCLUSION: Despite a shift to virtual visits and a decrease in A1c measurement during the pandemic, we observed no association with A1c level or short-term T2D-related outcomes, providing some reassurance about the adequacy of virtual visits. Further studies should assess the longer-term effects of shifting to virtual visits in different populations to help individualize care, improve efficiency, and maintain appropriate care while reducing overuse.

Telehealth and delivery of alcohol use disorder treatment in the Veterans Health Administration.

BACKGROUND: The use of telehealth treatment of alcohol use disorder (AUD) has increased since the start of the COVID-19 pandemic. However, it is unclear which patients are using telehealth and how telehealth visits are associated with treatment duration. This study examined characteristics associated with telehealth use among Veterans Health Administration patients receiving AUD treatment. METHODS: Using a national retrospective cohort study, we examined data from March 01, 2020 to February 28, 2021 to: First, identify patient characteristics associated with (a) any telehealth versus only in-person care for AUD treatment, and (b) video (≥1 video visit) versus only telephone visits for AUD treatment (≥1 telephone visit, no video) among any telehealth users. This analysis used mixed-effects logistic regression models to adjust for potential correlation across patients treated at the same facility. Second, we assessed whether visit modality was associated with the amount of AUD treatment received (number of AUD psychotherapy visits or medication coverage days). This analysis used mixed-effects negative binomial regression models. RESULTS: Among 138,619 patients who received AUD treatment, 52.8% had ≥1 video visit, 38.1% had ≥1 telephone but no video visits, and 9.1% had only in-person visits. In the regression analyses, patients who were male or had an opioid or stimulant use disorder (compared to having no non-AUD substance use disorder) were less likely to receive any telehealth-delivered AUD treatment compared to only in-person AUD treatment. Among patients who received any telehealth-delivered AUD treatment, those who were ≥45 years old (compared to 18-29 years old), Black (compared to White), diagnosed with a cannabis or stimulant use disorder, or diagnosed with a serious mental illness were less likely to receive a video visit than only telephone visits. Receiving any AUD telehealth was associated with receiving more psychotherapy visits and medication coverage days than only in-person care. CONCLUSIONS: Telehealth, a common modality for AUD treatment, supported a greater number of psychotherapy visits and a longer duration of medication treatment for AUD. However, some groups were less likely to receive any video telehealth than telephone visits, suggesting that multiple treatment modalities should remain available to ensure treatment access.

Pharmacist Use of a Population Management Dashboard for Safe Anticoagulant Prescribing: Evaluation of a Nationwide Implementation Effort.

BACKGROUND: Direct oral anticoagulants (DOACs) have complex dosing regimens and are often incorrectly prescribed. We evaluated a nationwide DOAC population management dashboard rollout whose purpose includes pharmacist review and correction of off-label dosing prescriptions. METHODS AND RESULTS: Using data from Veterans Health Affairs, we identified all patients prescribed DOACs for atrial fibrillation or venous thromboembolism between August 2015 and December 2019. Sites were grouped on the basis of the timing of moderate-high usage of the DOAC population management tool dashboard. Effectiveness was defined as the monthly rate of off-label DOAC prescribing and the rate of clinical adverse events (bleeding, composite of stroke or venous thromboembolism). Implementation was evaluated as the percentage of off-label DOAC prescriptions changed within 7 days. Among the 128 652 patients receiving DOAC therapy at 123 centers, between 6.9% and 8.6% had off-label DOAC prescriptions. Adoption of the DOAC population management tool dashboard before July 2018 was associated with a decline in off-label dosing prescriptions (8.7%-7.6%). Only 1 group demonstrated a significant reduction in monthly rates of bleeding following implementation. All sites experienced a reduction in the composite of venous thromboembolism or stroke following dashboard adoption. There was no difference in the implementation outcome of DOAC prescription change within 7 days in any of the adoption groups. CONCLUSIONS: Early adoption of the DOAC population management tool dashboard was associated with decreased rates of off-label DOAC dosing prescription and reduced bleeding. Following adoption of the DOAC population management tool dashboard, all sites experienced reductions in venous thromboembolism and stroke events.

Pedometer-based internet-mediated intervention for adults with chronic low back pain: randomized controlled trial.

BACKGROUND: Chronic pain, especially back pain, is a prevalent condition that is associated with disability, poor health status, anxiety and depression, decreased quality of life, and increased health services use and costs. Current evidence suggests that exercise is an effective strategy for managing chronic pain. However, there are few clinical programs that use generally available tools and a relatively low-cost approach to help patients with chronic back pain initiate and maintain an exercise program. OBJECTIVE: The objective of the study was to determine whether a pedometer-based, Internet-mediated intervention can reduce chronic back pain-related disability. METHODS: A parallel group randomized controlled trial was conducted with 1:1 allocation to the intervention or usual care group. 229 veterans with nonspecific chronic back pain were recruited from one Department of Veterans Affairs (VA) health care system. Participants randomized to the intervention received an uploading pedometer and had access to a website that provided automated walking goals, feedback, motivational messages, and social support through an e-community (n=111). Usual care participants (n=118) also received the uploading pedometer but did not receive the automated feedback or have access to the website. The primary outcome was measured using the Roland Morris Disability Questionnaire (RDQ) at 6 months (secondary) and 12 months (primary) with a difference in mean scores of at least 2 considered clinically meaningful. Both a complete case and all case analysis, using linear mixed effects models, were conducted to assess differences between study groups at both time points. RESULTS: Baseline mean RDQ scores were greater than 9 in both groups. Primary outcome data were provided by approximately 90% of intervention and usual care participants at both 6 and 12 months. At 6 months, average RDQ scores were 7.2 for intervention participants compared to 9.2 for usual care, an adjusted difference of 1.6 (95% CI 0.3-2.8, P=.02) for the complete case analysis and 1.2 (95% CI -0.09 to 2.5, P=.07) for the all case analysis. A post hoc analysis of patients with baseline RDQ scores ≥4 revealed even larger adjusted differences between groups at 6 months but at 12 months the differences were no longer statistically significant. CONCLUSIONS: Intervention participants, compared with those receiving usual care, reported a greater decrease in back pain-related disability in the 6 months following study enrollment. Between-group differences were especially prominent for patients reporting greater baseline levels of disability but did not persist over 12 months. Primarily, automated interventions may be an efficient way to assist patients with managing chronic back pain; additional support may be needed to ensure continuing improvements.

Rising use of surveillance colonoscopy and potential impacts.

OBJECTIVES: To quantify temporal changes in colonoscopy indication and assess appropriateness of surveillance use in older adults. STUDY DESIGN: Retrospective longitudinal study of national Veterans Health Administration (VHA) data of all patients who underwent outpatient colonoscopy in 2005-2014. METHODS: After validating an electronic algorithm for classifying colonoscopy indication in VHA, we examined trends in colonoscopy indication over time and across patient characteristics. RESULTS: The proportion of colonoscopies performed for postpolypectomy surveillance increased significantly during the study period, particularly among older patients with limited life expectancy, raising concern for possible overuse. CONCLUSIONS: Guidelines should make clear recommendations about when and how to discontinue postpolypectomy surveillance colonoscopy. Doing so would potentially reduce harms due to complications from low-value procedures and in turn moderate demand and thereby enhance overall procedural access for patients more likely to benefit.

Effects of an Electronic Medical Record Intervention on Appropriateness of Transthoracic Echocardiograms: A Prospective Study.

BACKGROUND: Transthoracic echocardiograms (TTEs) account for approximately half of U.S. spending on cardiac imaging. We developed an electronic medical record (EMR)-based decision-support algorithm for TTE ordering and hypothesized that it would increase the appropriateness of TTE orders. METHODS: This prospective observational study was performed at the Veterans Affairs Ann Arbor Healthcare System. From October to December 2016 (preintervention), consecutive TTEs ordered in the inpatient, outpatient, and emergency department settings were included. In May 2017, a decision-support algorithm was incorporated into the EMR, giving immediate feedback to providers. Chart review was performed for TTEs ordered from June to August 2017 (early intervention) and from June to August 2018 (late intervention). Appropriateness was determined based on the 2011 appropriate use criteria for echocardiography. RESULTS: Appropriate TTE orders increased from 87.6% preintervention to 94.5% at early intervention (z = 0.00018) but decreased to 90.0% at late intervention (z = 0.51, compared with preintervention). Among patients with no previous TTEs in our system, 95.3% of TTEs were appropriate, compared with 87.7% of TTEs for patients with prior TTEs within 30 days prior (odds ratio = 2.85; 95% CI, 1.18-6.31; P = .005). CONCLUSIONS: The EMR algorithm initially increased the percentage of appropriate TTEs, but this effect decayed over time. Further study is needed to develop EMR-based interventions that will have lasting impacts on provider ordering patterns.

Comparison of Payment Changes and Choosing Wisely Recommendations for Use of Low-Value Laboratory Tests in the United States and Canada.

Importance: Evidence comparing the consequences of Choosing Wisely recommendations across health systems or with the consequences of recommendations plus policy change is lacking. Objectives: To compare changes in the use of 2 low-value laboratory tests after the release of Choosing Wisely recommendations across 3 health care jurisdictions and changes associated with a related policy change. Design, Setting, and Participants: This cross-sectional study was a population-based interrupted time series of adult patients (aged 18-64 years) who had primary care visits between January 1, 2010, and June 30, 2015, or established hypothyroidism between January 1, 2012, and June 30, 2015, across 3 health care delivery jurisdictions: Ontario, Canada; the US Veterans Health Administration; and the US employer-sponsored insurance market. Data analysis was performed from March 21, 2018, to October 31, 2019. Exposures: A December 2010 payment policy change that eliminated reimbursement of vitamin D screening in Ontario, Canada, and the subsequent release of Choosing Wisely recommendations against low-value use of vitamin D tests in February 2013 and triiodothyronine tests in October 2013 in the United States and both tests in October 2014 in Canada. Main Outcomes and Measures: Relative marginal effects (RMEs) comparing low-value testing rates after the release of Choosing Wisely recommendations with rates expected based on prerelease trends and the associated change in low-value vitamin D testing after the 2010 payment policy change in Ontario, Canada. Results: Of 54 223 448 total persons, 28 504 576 (52.6%) were female, with 17 895 458 persons (33.0%) aged 18 to 34 years, 11 101 985 (20.5%) aged 35 to 44 years, and 25 226 005 (46.5%) aged 45 to 64 years. The December 2010 policy eliminating reimbursement for low-value vitamin D screening in Ontario, Canada, was associated with a 92.7% (95% CI, 92.4%-93.0%) relative reduction in such screening. Corresponding Choosing Wisely recommendations were associated with smaller reductions: 4.5% (95% CI, 2.6%-6.3%) in Ontario, 13.8% (95% CI, 11.8%-15.9%) for US Veterans Health Administration, and 14.0% (95% CI, 12.8%-15.2%) for US employer-sponsored insurance. In contrast, low-value use of triiodothyronine testing did not change significantly in Ontario, Canada (RME, 0.3%; 95% CI, -1.4% to 2.0%) or the US Veterans Health Administration (RME, 0.7%; 95% CI, -4.7% to 6.4%) and increased (RME, 3.0%; 95% CI, 1.6%-4.4%) for US employer-sponsored insurance. Conclusions and Relevance: In this study, marginal reductions in the use of 2 low-value laboratory tests were associated with the release of related Choosing Wisely recommendations but a greater reduction in low-value vitamin D screening was associated with a previous payment policy change implemented in Ontario, Canada. These findings suggest that recommendations alone may be insufficient to significantly reduce use of low-value services and that pairing recommendations with policy changes may be more effective.

More than a pain in the neck: how discussing chronic pain affects hypertension medication intensification.

BACKGROUND: A difficult to manage comorbid condition, like chronic pain, could adversely affect the delivery of recommended care for other serious health problems, such as hypertension. OBJECTIVE: We examined whether addressing pain at a primary care visit acts as a competing demand in decisions to intensify blood pressure (BP) medications for diabetic patients with an elevated BP. DESIGN: Prospective cohort study. PARTICIPANTS: 1,169 diabetic patients with a BP > or = 140/90 prior to a primary care provider (PCP) visit were enrolled. MEASUREMENTS: After the visit, PCPs provided information about the top three issues discussed and whether hypertension medications were intensified or reasons for not intensifying. We used multi-level logistic regression to assess whether discussing pain during the visit decreased the likelihood of BP medication intensification. We calculated predicted probabilities of medication intensification by whether pain was discussed. RESULTS: PCPs discussed pain during 222 (20%) of the visits. Visit BP did not differ between patients with whom pain was and was not discussed. BP medications were intensified during 44% of the visits. The predicted probability of BP medication intensification when pain was discussed was significantly lower than when pain was not discussed (35% vs. 46%, p = 0.02). CONCLUSIONS: Discussing pain at a primary care visit competed with the intensification of BP medication. This finding is concerning given that controlling blood pressure may be the most important factor in decreasing long-term complications for patients with diabetes. Better care management models for complex patients are needed to ensure that both pain and other chronic conditions are adequately addressed.

Effects of Guideline and Formulary Changes on Statin Prescribing in the Veterans Affairs.

OBJECTIVE: To compare the effects of two sequential policy changes-the addition of a high-potency statin to the Department of Veterans Affairs (VA) formulary and the release of the American College of Cardiology/American Heart Association (ACC/AHA) cholesterol guidelines-on VA provider prescribing. DATA SOURCES/STUDY SETTING: Retrospective analysis of 1,100,682 VA patients, 2011-2016. STUDY DESIGN: Interrupted time-series analysis of changes in prescribing of moderate-to-high-intensity statins among high-risk patients and across high-risk subgroups. We also assessed changes in prescribing of atorvastatin and other statin drugs. We estimated marginal effects (ME) of formulary and guideline changes by comparing predicted and observed statin use. DATA COLLECTION/EXTRACTION METHODS: Data from VA Corporate Data Warehouse. PRINCIPAL FINDINGS: The use of moderate-to-high-intensity statins increased by 2 percentage points following the formulary change (ME, 2.4, 95% confidence interval [CI], 2.2 to 2.6) and less than 1 percentage point following the guideline change (ME, 0.8, 95% CI, 0.6 to 0.9). The formulary change led to approximately a 12 percentage-point increase in the use of moderate-to-high-intensity atorvastatin (ME, 11.5, 95% CI, 11.3 to 11.6). The relatively greater provider response to the formulary change occurred across all patient subgroups. CONCLUSIONS: Addition of a high-potency statin to formulary affected provider prescribing more than the ACC/AHA guidelines.

Neuroimaging overuse is more common in Medicare compared with the VA.

OBJECTIVE: To inform initiatives to reduce overuse, we compared neuroimaging appropriateness in a large Medicare cohort with a Department of Veterans Affairs (VA) cohort. METHODS: Separate retrospective cohorts were established in Medicare and in VA for headache and neuropathy from 2004 to 2011. The Medicare cohorts included all patients enrolled in the Health and Retirement Study (HRS) with linked Medicare claims (HRS-Medicare; n = 1,244 for headache and 998 for neuropathy). The VA cohorts included all patients receiving services in the VA (n = 93,755 for headache and 183,642 for neuropathy). Inclusion criteria were age over 65 years and an outpatient visit for incident neuropathy or a primary headache. Neuroimaging use was measured with Current Procedural Terminology codes and potential overuse was defined using published criteria for use with administrative data. Increasingly specific appropriateness criteria excluded nontarget conditions for which neuroimaging may be appropriate. RESULTS: For both peripheral neuropathy and headache, potentially inappropriate imaging was more common in HRS-Medicare compared with the VA. Forty-nine percentage of all headache patients received neuroimaging in HRS-Medicare compared with 22.1% in the VA (p < 0.001) and differences persist when analyzing more specific definitions of overuse. A total of 23.7% of all HRS-Medicare incident neuropathy patients received neuroimaging compared with 9.0% in the VA (p < 0.001), and the difference persisted after excluding nontarget conditions. CONCLUSIONS: Overuse of neuroimaging is likely less common in the VA than in a Medicare population. Better understanding the reasons for the more selective use of neuroimaging in the VA could help inform future initiatives to reduce overuse of diagnostic testing.

Iraq and Afghanistan veterans with PTSD participate less in VA's weight loss program than those without PTSD.

BACKGROUND: Three-quarters of Iraq and Afghanistan veterans enrolled in Veterans Health Administration (VHA) care are overweight or obese. The VHA MOVE!® weight management program can mitigate the risks of obesity-related morbidity. However, many Iraq and Afghanistan veterans experience barriers to VHA services, which may affect participation, especially among those with posttraumatic stress disorder (PTSD) and/or depression. Little is known about MOVE! engagement among recent veterans. We describe a retrospective evaluation of MOVE! participation among Iraq and Afghanistan veterans with and without mental health problems. METHODS: As part of a national VHA mental health evaluation study, we accessed VHA patient care databases to identify Iraq and Afghanistan veterans receiving care from 2008-2013 who had ≥1 MOVE! visit(s) and ≥1 weight measurements (N=24,899). We used logistic regression to determine whether mental health conditions were associated with having 12 visits/year (desirable dose of care), adjusting for demographic, health, and utilization factors. RESULTS: Among Iraq and Afghanistan veterans enrolled in MOVE!, 4% had a desirable dose of participation. In adjusted models, desirable MOVE! participation was more likely among those without PTSD; those who were older, female, and unmarried; and those who had higher baseline weight, more medical comorbidities, no pain, psychotropic medication use, higher disability ratings, and more mental health visits. LIMITATIONS: We used administrative ICD-9 codes. Sample only included veterans in VHA care. CONCLUSIONS: Iraq and Afghanistan veterans, particularly those with PTSD, had low participation in VHA weight management programming. Correlates of MOVE! participation were identified, highlighting opportunities to tailor MOVE! to improve participation for these veterans.

Rates of Deintensification of Blood Pressure and Glycemic Medication Treatment Based on Levels of Control and Life Expectancy in Older Patients With Diabetes Mellitus.

IMPORTANCE: Older patients with diabetes mellitus receiving medical treatment whose blood pressure (BP) or blood glucose level are potentially dangerously low are rarely deintensified. Given the established risks of low blood pressure and blood glucose, this is a major opportunity to decrease medication harm. OBJECTIVE: To examine the rate of BP- and blood glucose-lowering medicine deintensification among older patients with type 1 or 2 diabetes mellitus who potentially receive overtreatment. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study conducted using data from the US Veterans Health Administration. Participants included 211 667 patients older than 70 years with diabetes mellitus who were receiving active treatment (defined as BP-lowering medications other than angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, or glucose-lowering medications other than metformin hydrochloride) from January 1 to December 31, 2012. Data analysis was performed December 10, 2013, to July 20, 2015. EXPOSURES: Participants were eligible for deintensification of treatment if they had low BP or a low hemoglobin A1c (HbA1c) level in their last measurement in 2012. We defined very low BP as less than 120/65 mm Hg, moderately low as systolic BP of 120 to 129 mm Hg or diastolic BP (DBP) less than 65 mm Hg, very low HbA1c as less than 6.0%, and moderately low HbA1c as 6.0% to 6.4%. All other values were not considered low. MAIN OUTCOMES AND MEASURES: Medication deintensification, defined as discontinuation or dosage decrease within 6 months after the index measurement. RESULTS: The actively treated BP cohort included 211,667 participants, more than half of whom had moderately or very low BP levels. Of 104,486 patients with BP levels that were not low, treatment in 15.1% was deintensified. Of 25,955 patients with moderately low BP levels, treatment in 16.0% was deintensified. Among 81,226 patients with very low BP levels, 18.8% underwent BP medication deintensification. Of patients with very low BP levels whose treatment was not deintensified, only 0.2% had a follow-up BP measurement that was elevated (BP ≥140/90 mm Hg). The actively treated HbA1c cohort included 179,991 participants. Of 143,305 patients with HbA1c levels that were not low, treatment in 17.5% was deintensified. Of 23,769 patients with moderately low HbA1c levels, treatment in 20.9% was deintensified. Among 12,917 patients with very low HbA1c levels, 27.0% underwent medication deintensification. Of patients with very low HbA1c levels whose treatment was not deintensified, fewer than 0.8% had a follow-up HbA1c measurement that was elevated (≥7.5%). CONCLUSIONS AND RELEVANCE: Among older patients whose treatment resulted in very low levels of HbA1c or BP, 27% or fewer underwent deintensification, representing a lost opportunity to reduce overtreatment. Low HbA1c or BP values or low life expectancy had little association with deintensification events. Practice guidelines and performance measures should place more focus on reducing overtreatment through deintensification.

Factors associated with persistent poorly controlled diabetes mellitus: clues to improving management in patients with resistant poor control.

OBJECTIVES: Patients with persistent poorly controlled diabetes mellitus (PPDM), defined as an uninterrupted hemoglobin A1c >8.0% for ≥1 year despite standard care, are at high risk for complications. Additional research to define patient factors associated with PPDM could suggest barriers to improvement in this group and inform the development of targeted strategies to address these patients' resistant diabetes. METHODS: We analyzed patients with type 2 diabetes from a multi-site randomized trial. We characterized patients with PPDM relative to other patients using detailed survey data and multivariable modeling. RESULTS: Of 963 patients, 118 (12%) had PPDM, 265 (28%) were intermittently poorly controlled, and 580 (60%) were well-controlled. Patients with PPDM had younger age, earlier diabetes diagnosis, insulin use, higher antihypertensive burden, higher low-density lipoprotein cholesterol, and lower statin use relative to well-controlled patients. Among patients with objective adherence data (Veterans Affairs patients), a larger oral diabetes medication refill gap was associated with PPDM. DISCUSSION: Strategies are needed to target-specific barriers to improvement among patients whose diabetes is resistant to standard diabetes care. Our data suggest that strategies for targeting PPDM should accommodate younger patients' lifestyles, include medication management for insulin titration and comorbid disease conditions, and address barriers to self-management adherence.

Assessing appropriateness of lipid management among patients with diabetes mellitus: moving from target to treatment.

BACKGROUND: Performance measures that emphasize only a treat-to-target approach may motivate overtreatment with high-dose statins, potentially leading to adverse events and unnecessary costs. We developed a clinical action performance measure for lipid management in patients with diabetes mellitus that is designed to encourage appropriate treatment with moderate-dose statins while minimizing overtreatment. METHODS AND RESULTS: We examined data from July 2010 to June 2011 for 964 818 active Veterans Affairs primary care patients ≥18 years of age with diabetes mellitus. We defined 3 conditions as successfully meeting the clinical action measure for patients 50 to 75 years old: (1) having a low-density lipoprotein (LDL) <100 mg/dL, (2) taking a moderate-dose statin regardless of LDL level or measurement, or (3) receiving appropriate clinical action (starting, switching, or intensifying statin therapy) if LDL is ≥100 mg/dL. We examined possible overtreatment for patients ≥18 years of age by examining the proportion of patients without ischemic heart disease who were on a high-dose statin. We then examined variability in measure attainment across 881 facilities using 2-level hierarchical multivariable logistic models. Of 668 209 patients with diabetes mellitus who were 50 to 75 years of age, 84.6% passed the clinical action measure: 67.2% with LDL <100 mg/dL, 13.0% with LDL ≥100 mg/dL and either on a moderate-dose statin (7.5%) or with appropriate clinical action (5.5%), and 4.4% with no index LDL on at least a moderate-dose statin. Of the entire cohort ≥18 years of age, 13.7% were potentially overtreated. Facilities with higher rates of meeting the current threshold measure (LDL <100 mg/dL) had higher rates of potential overtreatment (P<0.001). CONCLUSIONS: Use of a performance measure that credits appropriate clinical action indicates that almost 85% of diabetic veterans 50 to 75 years of age are receiving appropriate dyslipidemia management. However, many patients are potentially overtreated with high-dose statins.

Sedentary behavior and psychiatric symptoms in overweight and obese adults with schizophrenia and schizoaffective disorders (WAIST Study).

OBJECTIVE: Examine the association between sedentary behavior and psychiatric symptoms among overweight and obese adults with schizophrenia or schizoaffective disorders (SZO/SA). DESIGN: Randomized clinical trial; Weight Assessment and Intervention in Schizophrenia Treatment (WAIST) Study: baseline data collected 2005-2008. SETTING: University of Pittsburgh Medical Center, Pittsburgh, PA, USA. PARTICIPANTS: Community-dwelling adults diagnosed with SZO/SA, with mild symptom severity [Positive and Negative Syndrome Scale (PANSS)<90], who were interested in losing weight, age 18-70years, BMI>27kg/m(2). MEASUREMENTS: Objectively measured sedentary behavior by accelerometry, and psychopathology assessed by PANSS. Participants wore the actigraphs for 7 consecutive days during their waking hours. Sedentary behavior was defined as ≤100 counts per minute during wear-time and excluded sleep and non-wear time. RESULTS: On average, 81% of the participant's monitoring time or 756min/day was classified as sedentary behavior using accelerometry. No association was observed between sedentary behaviors and PANSS psychiatric symptoms [total (p≥0.75), positive (p≥0.81), negative (p≥0.59) and general psychopathology (p≥0.65) subscales]. No association was observed between sedentary behaviors and age, race, gender and BMI. CONCLUSION: From a clinical and public health perspective, the amount of time (approximately 13h) and percentage of time (81% excluding non-wear time associated with sleeping) engaged in sedentary behavior among overweight and obese adults in this population is alarming, and points to an urgent need for interventions to decrease sedentary behaviors. The lack of associations between sedentary behavior and psychiatric symptoms may be due to a ceiling effect for sedentary behavior.

Monitoring performance for blood pressure management among patients with diabetes mellitus: too much of a good thing?

BACKGROUND: Performance measures that reward achieving blood pressure (BP) thresholds may contribute to overtreatment. We developed a tightly linked clinical action measure designed to encourage appropriate medical management and a marker of potential overtreatment, designed to monitor overly aggressive treatment of hypertension in the face of low diastolic BP. METHODS: We conducted a retrospective cohort study in 879 Department of Veterans Affairs (VA) medical centers and smaller community-based outpatient clinics. The clinical action measure for hypertension was met if the patient had a passing index BP at the visit or had an appropriate action. We examined the rate of passing the action measure and of potential overtreatment in the Veterans Health Administration during 2009-2010. RESULTS: There were 977,282 established VA patients, 18 years and older, with diabetes mellitus (DM). A total of 713,790 patients were eligible for the action measure; 94% passed the measure (82% because they had a BP <140/90 mm Hg at the visit and an additional 12% with a BP ≥140/90 mm Hg and appropriate clinical actions). Facility pass rates varied from 77% to 99% (P < .001). Among all patients with DM, 197,291 (20%) had a BP lower than 130/65 mm Hg; of these, 80 903 (8% of all patients with DM) had potential overtreatment. Facility rates of potential overtreatment varied from 3% to 20% (P < .001). Facilities with higher rates of meeting the current threshold measure (<140/90 mm Hg) had higher rates of potential overtreatment (P < .001). CONCLUSIONS: While 94% of diabetic veterans met the action measure, rates of potential overtreatment are currently approaching the rate of undertreatment, and high rates of achieving current threshold measures are directly associated with overtreatment. Implementing a clinical action measure for hypertension management, as the Veterans Health Administration is planning to do, may result in more appropriate care and less overtreatment.
