    ABSTRACT: Patient-centered medical homes (PCMHs) are a newer paradigm of health care service delivery. Team-based care that includes pharmacists has been implemented in several countries. Subsequently studies have successfully identified challenges and barriers with team-based care. Research on pharmacists' integration into PCMH is warranted to help bridge knowledge from earlier studies exploring team-based care. In 2010, the Department of Veteran Affairs (VA) began a national PCMH implementation, operationalized as "Patient-Aligned Care Teams" (PACTs). The VA's national PACT implementation presents an opportunity to describe other persistent barriers to effective coordination between primary care and pharmacy providers.

    ABSTRACT: This paper examines blood pressure (BP) control after 6 months of an intensive pharmacist-managed intervention in a mixed-methods randomized controlled trial conducted at the Iowa City Veteran Affairs Health Care System and two community-based outreach clinics. Patients received the pharmacist intervention for the first 6 months. The study coordinator conducted a summative evaluation with 37 patients 18 to 24 months following the initial 6-month intervention period. BP was significantly reduced in diabetic patients following an intensive pharmacist intervention (-8.0/-4.0±14.4/9.1 mm Hg systolic/diastolic, P<.001 and P=.001, respectively). BP was reduced even more in nondiabetic patients (-14.0/-5.0±1.9/10.0 mm Hg, P<.001). Medication adherence significantly improved from baseline to 6 months (P=.017). BPs were significantly lower at 6 months following an intensive pharmacist intervention. Patients also expressed a high level of satisfaction with and preference for co-management of their hypertension, as well as other chronic diseases.

    ABSTRACT: There is little objective evidence to support concerns that patients are transferred between hospitals based on insurance status. To examine the relationship between patients' insurance coverage and interhospital transfer. Data analyzed from the 2010 Nationwide Inpatient Sample. All patients aged 18 to 64 years discharged alive from U.S. acute care hospitals with 1 of 5 common diagnoses (biliary tract disease, chest pain, pneumonia, septicemia, and skin or subcutaneous infection). For each diagnosis, the proportion of hospitalized patients who were transferred to another acute care hospital based on insurance coverage (private, Medicare, Medicaid, or uninsured) was compared. Logistic regression was used to estimate the odds of transfer for uninsured patients (reference category, privately insured) while patient- and hospital-level factors were adjusted for. All analyses incorporated sampling and poststratification weights. Among 315 748 patients discharged from 1051 hospitals with any of the 5 diagnoses, the percentage of patients transferred to another acute care hospital varied from 1.3% (skin infection) to 5.1% (septicemia). In unadjusted analyses, uninsured patients were significantly less likely to be transferred for 3 diagnoses (P 0.05). In adjusted analyses, uninsured patients were significantly less likely to be transferred than privately insured patients for 4 diagnoses: biliary tract disease (odds ratio, 0.73 [95% CI, 0.55 to 0.96]), chest pain (odds ratio, 0.63 [CI, 0.44 to 0.89]), septicemia (odds ratio, 0.76 [CI, 0.64 to 0.91]), and skin infections (odds ratio, 0.64 [CI, 0.46 to 0.89]). Women were significantly less likely to be transferred than men for all diagnoses. This analysis relied on administrative data and lacked clinical detail. Uninsured patients (and women) were significantly less likely to undergo interhospital transfer. Differences in transfer rates may contribute to health care disparities.

    ABSTRACT: Background Patient-centered medical homes (PCMHs) are a newer paradigm of health care service delivery. Team-based care that includes pharmacists has been implemented in several countries. Subsequently studies have successfully identified challenges and barriers with team-based care. Research on pharmacists’ integration into PCMH is warranted to help bridge knowledge from earlier studies exploring team-based care. In 2010, the Department of Veteran Affairs (VA) began a national PCMH implementation, operationalized as “Patient-Aligned Care Teams” (PACTs). The VA’s national PACT implementation presents an opportunity to describe other persistent barriers to effective coordination between primary care and pharmacy providers. Objective To identify perceived barriers and facilitators to pharmacist integration into VA PACTs from the perspective of non-pharmacist team members. Methods Semi-structured interviews were conducted as part of a formative evaluation of PCMH implementation. Participants were from VA medical centers and community-based outpatient clinics in the Midwestern United States and included physicians, nurses, associated health care professionals, and health system administrators. Results In working toward pharmacy service integration, role clarity and work activities were influenced by team member attitudes towards and previous experiences with pharmacists. Interviewees reported that coordination with pharmacists was hindered if communication placed extra burdens on other team members. Interviewees reported collaboration was easier when pharmacists were on-site, but that technology helped facilitate off-site access to pharmacy services. Finally, some team members characterized pharmacist integration as essential while others failed to integrate pharmacists at all. Conclusion Non-pharmacist members of PACT teams reported some reluctance in pharmacists’ integration. They attributed this reluctance to knowledge deficits, limited participation in PACT training by pharmacists, an imbalance in effort expended for pharmacists’ integration, and coordination or communication challenges. While there may be unique opportunities for pharmacists to improve patient care through participation in PCMHs, work remains to improve other health professionals’ knowledge of and attitudes towards pharmacists’ roles on health care teams.

    ABSTRACT: Implementation of a patient centered medical home challenges primary care providers to change their scheduling practices to enhance patient access to care as well as to learn how to use performance metrics as part of a self-reflective practice redesign culture. As medical homes become more commonplace, health care administrators and primary care providers alike are eager to identify barriers to implementation. The objective of this study was to identify non-technological barriers to medical home implementation from the perspective of primary care providers. We conducted qualitative interviews with providers implementing the medical home model in Department of Veterans Affairs clinics—the most comprehensive rollout to date. Primary care providers reported favorable attitudes towards the model but discussed the importance of data infrastructure for practice redesign and panel management. Respondents emphasized the need for administrative leadership to support practice redesign by facilitating time for panel management and recognizing providers who utilize non-face-to-face ways of delivering clinical care. Health care systems considering adoption of the medical home model should ensure that they support both technological capacities and vertically aligned expectations for provider performance.

    ABSTRACT: Blood pressure exhibits circadian variability, and nighttime blood pressure is one of the best predictors of cardiovascular (CV) events. Adults with hypertension who lack a nighttime dipping pattern are at particularly high risk. Several studies have found that bedtime dosing of antihypertensive agents reduces sleep blood pressure and improves the dipping pattern in nondippers. One small study and 2 substudies of diabetes and chronic kidney disease suggest that bedtime dosing of ≥1 antihypertensives significantly reduced CV events. A Cochrane review of 5 studies found no difference in adverse events between morning and evening dosing. However, several evaluations in ophthalmology have found that nocturnal arterial hypotension precipitated ocular vascular disorders such as ischemic optic neuropathy. Some authors have suggested that additional studies of nighttime dosing of antihypertensive agents that evaluate CV events need to be conducted. The authors describe a randomized controlled pragmatic trial that is being planned at the University of Iowa and Duke University. Patients with hypertension and other comorbid conditions will be randomized to either continue morning dosing of all antihypertensive agents or to switch their nondiuretic medications to bedtime dosing. Patients will be followed for 36 to 42 months. This study will determine whether nighttime dosing reduces CV risk when compared with traditional morning dosing of antihypertensive agents.

    ABSTRACT: Each July, teaching hospitals experience an influx of new residents and fellows who have recently graduated from medical school or completed residency training programs. During this period, teaching hospitals also assign new positions of responsibility to existing residents and fellows. Medical education is a core mission of teaching hospitals, and in these hospitals, interns, residents, and fellows play major roles in patient care. This recurrent cycle in which care is delivered by less experienced physicians in the initial month of the academic year has led to the often expressed conventional wisdom of "not to get sick in July."(1) In addition to the lore surrounding July admissions to teaching hospitals, prior studies have shown that physician experience is an important determinant of outcomes for a wide range of medical conditions and procedures. (2-5) Moreover, literature from economics and other fields has shown that employee turnover can adversely affect organizational productivity.(6,7) Given that teaching hospitals face both inexperienced physicians as well as high turnover early in the academic year, it is reasonable to be concerned about the potential for lower quality care around that time.

    ABSTRACT: To examine whether racial disparities in usage and outcomes of total knee and total hip arthroplasty (TKA and THA) have declined over time. We used data from the US Medicare Program (MedPAR data) for years 1991-2008 to identify four separate cohorts of patients (primary TKA, revision TKA, primary THA, revision THA). For each cohort, we calculated standardised arthroplasty usage rates for Caucasian and African-American Medicare beneficiaries for each calendar year, and examined changes in disparities over time. We examined unadjusted and adjusted outcomes (30-day readmission rate, discharge disposition etc.) for Caucasians and African-Americans, and whether disparities decreased over time. In 1991, the use of primary TKA was 36% lower for African-Americans compared with Caucasians (20.6 per 10 000 for African-Americans; 32.1 per 10 000 for Caucasians; p<0.0001); in 2008, usage of primary TKA was 40% lower for African-Americans (41.5 per 10 000 for African-Americans; 68.8 per 10 000 for Caucasians; p<0.0001) with similar findings for the other cohorts. Black-White disparities in 30-day hospital readmission increased significantly from 1991-2008 among three patient cohorts. For example in 1991 30-day readmission rates for African-Americans receiving primary TKA were 6% higher than for Caucasians; by 2008 readmission rates for African-Americans were 24% higher (p<0.05 for change in disparity). Similarly, black-white disparities in the proportion of patients discharged to home after surgery increased across the study period for all cohorts (p<0.05). In an 18-year analysis of US Medicare data, we found little evidence of declines in racial disparities for joint arthroplasty usage or outcomes.

    ABSTRACT: To compare colorectal cancer screening rates in veterans receiving primary care (PC) in Veterans Administration (VA) community-based outpatient clinics (CBOCs) and VA medical centers (VAMCs). The VA Outpatient Care Files were used to identify 2 837 770 patients ≥50 years with ≥2 PC visits in 2010. Veterans undergoing screening/surveillance colonoscopy, sigmoidoscopy, fecal-occult-blood testing (FOBT), and double-contrast barium enema (DCBE) were identified from ICD-9-CM/CPT codes. Patients were categorized as VAMC (n = 1 403 273; 49.5%) or CBOC (1 434 497; 50.5%) based on where majority of PC encounters occurred and as high risk (n = 284 090) or average risk (n = 2 553 680) based on colorectal cancer risk factors and validated ICD-9-CM-based algorithms. CBOC patients were older than VAMC (mean ages 69.3 vs 67.4 years; P < .001), more likely (P < .001) to be male (96.5% vs 95.1%), and white (67.8% vs 64.2%), but less likely to be high-risk (9.4% vs 10.5%; P < .001). Rates of colonoscopy, sigmoidoscopy, and DCBE were all lower in CBOC (P < .001). Among high-risk veterans, rates in CBOC and VAMC, respectively, were 27.4% versus 36.8% for colonoscopy, 1.3% versus 0.8% for sigmoidoscopy, and 0.8% versus 0.5% for DCBE. Among average-risk veterans, these rates were 1.3% versus 1.9%, 0.2% versus 0.1%, and 0.2% versus 0.1%, respectively. The differences remained after adjusting for age/comorbidity. The adjusted odds of colonoscopy for CBOC were 0.73 (95% confidence interval = 0.64-0.82) for average risk and 0.76 (95% confidence interval = 0.67-0.87) for high risk. In contrast, the use of FOBT was relatively similar in CBOCs and VAMCs among both high risk (11.1% vs 11.2%) and average risk (14.3% vs 14.1%). Screening rates were similar between those younger than 65 years and older than 65 years. Veterans receiving PC in CBOCs are less likely to receive screening colonoscopy, sigmoidoscopy, and DCBE than VAMC according to VA records. The lower use in CBOC was not offset by higher use of FOBT, including the degree to which CBOC patients may be more reliant to use non-VA services. The clinical appropriateness of these differences merits further examination.

    ABSTRACT: Purpose:To examine the relationship between posttraumatic stress disorder (PTSD) and computed tomography (CT) utilization and to determine whether there were patterns of comorbid illness that could explain the relationship.Materials and Methods:The study was approved by the University of Iowa Institutional Review Board and the Iowa City Veterans Affairs Medical Center Research and Development Committee. By using a retrospective cohort design, a national sample of new veteran enrollees aged 18-35 years was studied. Associations were examined between the presence of PTSD, receipt of at least one and multiple CT scans, comorbid medical conditions (eg, abdominal pain, headaches), and measures of health care utilization (eg, primary care, emergency room, and mental health visits) and the daily probability of the receipt of at least one CT scan before and after a diagnosis of PTSD. Analyses included sequential multivariable generalized linear mixed models to examine the independent relationship between PTSD and CT scan utilization.Results:Among the full cohort, 13.0% (10 018 of 76 812) received at least one CT scan. PTSD was identified in 21.1% (16 182 of 76 812) of the cohort, and 22.9% (3711 of 16 182) of veterans with PTSD received at least one CT scan as compared with 10.4% (6307 of 60 630) of veterans without PTSD (P < .0001). In sequential modeling, comorbid factors explaining the relationship between CT scans and PTSD were traumatic brain injury (odds ratio, 3.54; P < .0001), abdominal pain (odds ratio, 4.01; P < .0001), and headaches (odds ratio, 3.07; P < .0001). Associations were also strong for high levels of emergency room (odds ratio, 2.73; P < .0001) and primary care (odds ratio, 2.38; P < .0001) utilization. The daily chance of receiving a CT scan was seven times higher prior to the recognition of PTSD (daily chance, 0.007 before vs 0.001 after; P < .0001).Conclusion:Young veterans with PTSD are receiving more CT scans compared with those without PTSD; the daily probability of receiving CT scans is higher prior to recognition of PTSD.© RSNA, 2013Supplemental material: http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.13121593/-/DC1.

    ABSTRACT: Chinese translation Reducing length of stay (LOS) has been a priority for hospitals and health care systems. However, there is concern that this reduction may result in increased hospital readmissions. To determine trends in hospital LOS and 30-day readmission rates for all medical diagnoses combined and 5 specific common diagnoses in the Veterans Health Administration. Observational study from 1997 to 2010. All 129 acute care Veterans Affairs hospitals in the United States. 4 124 907 medical admissions with subsamples of 2 chronic diagnoses (heart failure and chronic obstructive pulmonary disease) and 3 acute diagnoses (acute myocardial infarction, community-acquired pneumonia, and gastrointestinal hemorrhage). Unadjusted LOS and 30-day readmission rates with multivariable regression analyses to adjust for patient demographic characteristics, comorbid conditions, and admitting hospitals. For all medical diagnoses combined, risk-adjusted mean hospital LOS decreased by 1.46 days from 5.44 to 3.98 days, or 2% annually (P < 0.001). Reductions in LOS were also observed for the 5 specific common diagnoses, with greatest reductions for acute myocardial infarction (2.85 days) and community-acquired pneumonia (2.22 days). Over the 14 years, risk-adjusted 30-day readmission rates for all medical diagnoses combined decreased from 16.5% to 13.8% (P < 0.001). Reductions in readmissions were also observed for the 5 specific common diagnoses, with greatest reductions for acute myocardial infarction (22.6% to 19.8%) and chronic obstructive pulmonary disease (17.9% to 14.6%). All-cause mortality 90 days after admission was reduced by 3% annually. Of note, hospitals with mean risk-adjusted LOS that was lower than expected had a higher readmission rate, suggesting a modest tradeoff between hospital LOS and readmission (6% increase for each day lower than expected). This study is limited to the Veterans Health Administration system; non-Veterans Affairs admissions were not available. No measure of readmission preventability was used. Veterans Affairs hospitals demonstrated simultaneous improvements in hospital LOS and readmissions over 14 years, suggesting that as LOS improved, hospital readmission did not increase. This is important because hospital readmission is being used as a quality indicator and may result in payment incentives. Future work should explore these relationships to see whether a tipping point exists for LOS reduction and hospital readmission.

    ABSTRACT: Policies limiting exposure to cigarette smoke have been associated with reduced hospitalizations for heart attacks, but little is known about the impact of smoking bans on other health conditions and whether findings from individual communities generalize to other areas. We investigated the association between smoking bans targeting workplaces, restaurants, and bars passed throughout the United States during 1991-2008 and hospital admissions for smoking-related illnesses-acute myocardial infarction and chronic obstructive pulmonary disease-among Medicare beneficiaries age sixty-five or older. Risk-adjusted hospital admission rates for acute myocardial infarction fell 20-21 percent thirty-six months following implementation of new restaurant, bar, and workplace smoking bans. Admission rates for chronic obstructive pulmonary disease fell 11 percent where workplace smoking bans were in place and 15 percent where bar smoking bans were present. By contrast, very little effect was found for hospitalization for gastrointestinal hemorrhage and hip fracture-two conditions largely unrelated to smoking and examined as points of comparison. These findings provide further support for the public health benefits of laws that limit exposure to tobacco smoke.

    ABSTRACT: Abstract Background: Home telehealth programs often focus on a single disease, yet many patients who need monitoring have multiple conditions. This study evaluated secondary outcomes from a clinical trial evaluating the efficacy of home telehealth to improve outcomes of patients with co-morbid diabetes and hypertension. Subjects and Methods: A single-center randomized controlled clinical trial compared two remote monitoring intensity levels (low and high) and usual care in patients with type 2 diabetes and hypertension being treated in primary care. Secondary outcomes assessed were knowledge (diabetes, hypertension, medications), self-efficacy, adherence (diabetes, medications), and patient perceptions of the intervention mode. Results: Knowledge scores improved in the high-intensity intervention group participants, but upon further analysis, we found the intervention effect was not mediated by gain in knowledge. No significant differences were found across the groups in self-efficacy, adherence, or patient perceptions of the intervention mode. Conclusions: Home telehealth can enhance detection of key clinical symptoms that occur between regular physician visits. While our intervention improved glycemic and blood pressure control, the mechanism of the effect for this improvement was not clear.

    ABSTRACT: Evidence indicates that veterans using VA healthcare services have poor health-related quality of life (HRQOL). Little is known, however, about differences in HRQOL among those who only use VA services and those who also use non-VA services. We sought to evaluate differences in HRQOL among veterans who use: (1) only non-VA services (2) only VA services and (3) both VA and non-VA services (i.e., dual users). A cross-sectional study of 39,942 US veterans who completed the CDC’s 2004 Behavioral Risk Factor Surveillance System (BRFSS) survey was analyzed. Self-rated measures of global health status and the number of days per month that veterans were limited by physical or mental problems were extracted from BRFSS survey data as outcomes. Multivariate logistic regression demonstrated that, compared to those receiving all healthcare outside of VA, veterans receiving VA care were more likely to report poorer health outcomes, including worse global health status, greater impairments in physical functioning, and increased limitations regarding routine activities (p’s ≤ .05). Both exclusive and dual users of VA services reported poorer HRQOL than individuals not using VA services. More research is needed regarding veterans’ health status, particularly in the context of dual use.

    ABSTRACT: Specialty hospitals have lower mortality rates for cardiac revascularization than general hospitals, but previous studies have found that this advantage disappears after adjusting for patient characteristics and hospital procedural volume. Questions have been raised about whether simultaneous relationships between volume and mortality might have biased these analyses. We use two-stage least squares with Hospital Quality Alliance scores and estimated market size as instruments for mortality and volume to control for possible simultaneity. After this adjustment, it is still the case that specialty hospitals do not have an advantage over general hospitals in mortality rates after cardiac revascularization. We find evidence of simultaneity in the relationship between volume and mortality.

    ABSTRACT: Increased emphasis is being placed on the critical need to control hypertension (HTN) in patients with diabetes. The objective of this study was to evaluate the efficacy of a nurse-managed home telehealth intervention to improve outcomes in veterans with comorbid diabetes and HTN. A single-center, randomized, controlled clinical trial design comparing two remote monitoring intensity levels and usual care in patients with type 2 diabetes and HTN being treated in primary care was used. Primary outcomes were hemoglobin A1c and systolic blood pressure (SBP); secondary outcome was adherence. Intervention subjects experienced decreased A1c during the 6-month intervention period compared with the control group, but 6 months after the intervention was withdrawn, the intervention groups were comparable with the control group. For SBP, the high-intensity subjects had a significant decrease in SBP compared with the other groups at 6 months and this pattern was maintained at 12 months. Adherence improved over time for all groups, but there were no differences among the three groups. Subjects had relatively good baseline control for A1c and SBP; minorities and women were underrepresented. Home telehealth provides an innovative and pragmatic approach to enhance earlier detection of key clinical symptoms requiring intervention. Transmission of education and advice to the patient on an ongoing basis with close surveillance by nurses can improve clinical outcomes in patients with comorbid chronic illness.

    ABSTRACT: Surgical complications contribute substantially to costs. Most important, surgical complications contribute to morbidity and mortality, and some may be preventable. This study estimates costs of specific surgical complications for patients undergoing general surgery in VA hospitals using merged data from the VA Surgical Quality Improvement Program and VA Decision Support System. Costs associated with 19 potentially preventable complications within 6 broader categories were estimated using generalized, linear mixed regression models to control for patient-level determinants of costs (eg, type of operation, demographics, comorbidity, severity) and hospital-level variation in costs. Costs included costs of the index hospitalization and subsequent 30-day readmissions. In 14,639 patients undergoing general surgical procedures from 10/2005 through 9/2006, 20% of patients developed postoperative surgical complications. The presence of any complication significantly increased unadjusted costs nearly 3-fold ($61,083 vs $22,000), with the largest cost differential attributed to respiratory complications. Patients who developed complications had several markers for greater preoperative severity, including increased age and a lesser presurgery functional health status. After controlling for differences in patient severity, costs for patients with any complication were 1.89 times greater compared to costs for patients with no complications (P < .0001). Within major complication categories, adjusted costs were significantly greater for patients with respiratory, cardiac, central nervous system, urinary, wound, or other complications. Surgical complications contribute markedly to costs of inpatient operations. Investment in quality improvement that decreases the incidence of surgical complications could decrease costs.

    ABSTRACT: It is well known that older adults figure prominently in the use of emergency departments (ED) across the United States. Previous research has differentiated ED visits by levels of clinical severity and found health status and other individual characteristics distinguished severe from non-severe visits. In this research, we classified older adults into population groups that persistently present with severe, non-severe, or indeterminate patterns of ED episodes. We then contrasted the three groups using a comprehensive set of covariates. Using a unique dataset linking individual characteristics with Medicare claims for calendar years 1991-2007, we identified patterns of ED use among the large, nationally representative AHEAD sample consisting of 5,510 older adults. We then classified one group of older adults who persistently presented to the ED with clinically severe episodes and another group who persistently presented to the ED with non-severe episodes. These two groups were contrasted using logistic regression, and then contrasted against a third group with a persistent pattern of ED episodes with indeterminate levels of severity using multinomial logistic regression. Variable selection was based on Andersen's behavioral model of health services use and featured clinical status, demographic and socioeconomic characteristics, health behaviors, health service use patterns, local health care supply, and other contextual effects. We identified 948 individuals (17.2% of the entire sample) who presented a pattern in which their ED episodes were typically defined as severe and 1,076 individuals (19.5%) who typically presented with non-severe episodes. Individuals who persistently presented to the ED with severe episodes were more likely to be older (AOR 1.52), men (AOR 1.28), current smokers (AOR 1.60), experience diabetes (AOR (AOR 1.80), heart disease (AOR 1.70), hypertension (AOR 1.32) and have a greater amount of morbidity (AOR 1.48) than those who persistently presented to the ED with non-severe episodes. When contrasted with 1,177 individuals with a persistent pattern of indeterminate severity ED use, persons with severe patterns were older (AOR 1.36), more likely to be obese (AOR 1.36), and experience heart disease (AOR 1.49) and hypertension (AOR 1.36) while persons with non-severe patterns were less likely to smoke (AOR 0.63) and have diabetes (AOR 0.67) or lung disease (AOR 0.58). We distinguished three large, readily identifiable groups of older adults which figure prominently in the use of EDs across the United States. Our results suggest that one group affects the general capacity of the ED to provide care as they persistently present with severe episodes requiring urgent staff attention and greater resource allocation. Another group persistently presents with non-severe episodes and creates a considerable share of the excess demand for ED care. Future research should determine how chronic disease management programs and varied co-payment obligations might impact the use of the ED by these two large and distinct groups of older adults with consistent ED use patterns.
