Risk of Parkinson Disease Among Service Members at Marine Corps Base Camp Lejeune.

Importance: An increased risk of Parkinson disease (PD) has been associated with exposure to the solvent trichloroethylene (TCE), but data are limited. Millions of people in the US and worldwide are exposed to TCE in air, food, and water. Objective: To test whether the risk of PD is higher in veterans who served at Marine Corps Base Camp Lejeune, whose water supply was contaminated with TCE and other volatile organic compounds (VOCs), compared with veterans who did not serve on that base. Design, Setting, and Participants: This population-based cohort study examined the risk for PD among all Marines and Navy personnel who resided at Camp Lejeune, North Carolina (contaminated water) (n = 172 128), or Camp Pendleton, California (uncontaminated water) (n = 168 361), for at least 3 months between 1975 and 1985, with follow-up from January 1, 1997, until February 17, 2021. Veterans Health Administration and Medicare databases were searched for International Classification of Diseases diagnostic codes for PD or other forms of parkinsonism and related medications and for diagnostic codes indicative of prodromal disease. Parkinson disease diagnoses were confirmed by medical record review. Exposures: Water supplies at Camp Lejeune were contaminated with several VOCs. Levels were highest for TCE, with monthly median values greater than 70-fold the permissible amount. Main Outcome and Measures: Risk of PD in former residents of Camp Lejeune relative to residents of Camp Pendleton. In those without PD or another form of parkinsonism, the risk of being diagnosed with features of prodromal PD were assessed individually and cumulatively using likelihood ratio tests. Results: Health data were available for 158 122 veterans (46.4%). Demographic characteristics were similar between Camp Lejeune (5.3% women, 94.7% men; mean [SD] attained age of 59.64 [4.43] years; 29.7% Black, 6.0% Hispanic, 67.6% White; and 2.7% other race and ethnicity) and Camp Pendleton (3.8% women, 96.2% men; mean [SD] age, 59.80 [4.62] years; 23.4% Black, 9.4% Hispanic, 71.1% White, and 5.5% other race and ethnicity). A total of 430 veterans had PD, with 279 from Camp Lejeune (prevalence, 0.33%) and 151 from Camp Pendleton (prevalence, 0.21%). In multivariable models, Camp Lejeune veterans had a 70% higher risk of PD (odds ratio, 1.70; 95% CI, 1.39-2.07; P < .001). No excess risk was found for other forms of neurodegenerative parkinsonism. Camp Lejeune veterans also had a significantly increased risk of prodromal PD diagnoses, including tremor, anxiety, and erectile dysfunction, and higher cumulative prodromal risk scores. Conclusions and Relevance: The study's findings suggest that the risk of PD is higher in persons exposed to TCE and other VOCs in water 4 decades ago. Millions worldwide have been and continue to be exposed to this ubiquitous environmental contaminant.

Early Impact of VA MISSION Act Implementation on Primary Care Appointment Wait Time.

BACKGROUND: Through Community Care Networks (CCNs) implemented with the VA MISSION Act, VA expanded provider contracting and instituted network adequacy standards for Veterans' community care. OBJECTIVE: To determine whether early CCN implementation impacted community primary care (PC) appointment wait times overall, and by rural/urban and PC shortage area (HPSA) status. DESIGN: Using VA administrative data from February 2019 through February 2020 and a difference-in-differences approach, we compared wait times before and after CCN implementation for appointments scheduled by VA facilities that did (CCN appointments) and did not (comparison appointments) implement CCNs. We ran regression models with all appointments, and stratified by rural/urban and PC HPSA status. All models adjusted for Veteran characteristics and VA facility-level clustering. APPOINTMENTS: 13,720 CCN and 40,638 comparison appointments. MAIN MEASURES: Wait time, measured as number of days from authorization to use community PC to a Veteran's first corresponding appointment. KEY RESULTS: Overall, unadjusted wait times increased by 35.7 days ([34.4, 37.1] 95% CI) after CCN implementation. In adjusted analysis, comparison wait times increased on average 33.7 days ([26.3, 41.2] 95% CI, p < 0.001) after CCN implementation; there was no significant difference for CCN wait times (across-group mean difference: 5.4 days, [-3.8, 14.6] 95% CI, p = 0.25). In stratified analyses, comparison wait time increases ranged from 29.6 days ([20.8, 38.4] 95% CI, p < 0.001) to 42.1 days ([32.9, 51.3] 95% CI, p > 0.001) after CCN implementation, while additional differences for CCN appointments ranged from 13.4 days ([3.5, 23.4] 95% CI, p = 0.008) to -15.1 days ([-30.1, -0.1] 95% CI, p = 0.05) for urban and PC HPSA appointments, respectively. CONCLUSIONS: After early CCN implementation, community PC wait times increased sharply at VA facilities that did and did not implement CCNs, regardless of rural/urban or PC HPSA status, suggesting community care demand likely overwhelmed VA resources such that CCNs had limited impact.

An assessment of Veterans attitudes and willingness to receiving the COVID-19 vaccine: a mixed methods study.

BACKGROUND: While several safe and effective COVID-19 vaccines have been available since December 2020, many eligible individuals choose to remain unvaccinated. This vaccine hesitancy is an important factor affecting our ability to combat the COVID-19 pandemic. METHODS: The objective of the study was to examine the attitudes and willingness among US Veterans toward receiving COVID-19 vaccination. The study used a quantitative qualitative mixed methods design with a telephone survey and then in-depth interviews in a subset of those surveyed. Participants were unvaccinated Veterans (N = 184) selected randomly from a registry of patients who had received VA healthcare during the pandemic and had a diagnostic test for COVID-19. The primary outcome was willingness to accept COVID-19 vaccination. Survey data collection and in-depth interviews were conducted by telephone. Analyses of the survey data compared the primary outcome with demographics, clinical data, and survey responses using bivariate and multiple regression analyses. A subset (N = 10) of those surveyed, participated in an in-depth interview. Interview transcripts were analyzed to derive themes using qualitative content analysis. RESULTS: Almost 40% of participants disagreed they would receive a COVID-19 vaccine. Participants who were younger, female, and had fewer comorbid conditions were more likely (P < 0.05) to disagree with COVID-19 vaccination. In multiple regression analysis, willingness to accept vaccination was associated with reliance on a doctor or family member's recommendation and with a belief that vaccines are effective. In-depth interviews revealed several barriers to COVID-19 vaccination, including lack of trust in the government and vaccine manufacturers, concerns about the speed of vaccine development, fear of side effects, and fear the vaccine was a tool of racism. CONCLUSIONS: This study illustrates the complexity of patients' deliberation about COVID-19 vaccination and may help physicians and other health care providers understand patients' perspectives about COVID-19 vaccination. The results highlight the importance of patients' trust in physicians, healthcare organizations, pharmaceutical manufacturers and the government when making health decisions.

Veterans' Use of Veterans Health Administration Primary Care in an Era of Expanding Choice.

BACKGROUND: The Veterans Choice Program (VCP), aimed at improving access to care, included expanded options for Veterans to receive primary care through community providers. OBJECTIVES: The objective of this study was to characterize and compare Veterans use of Veterans Health Administration (VA) primary care services at VA facilities and through a VA community care network (VA-CCN) provider. RESEARCH DESIGN: This was a retrospective, observational over fiscal years (FY) 2015-2018. SUBJECTS: Veterans receiving primary care services paid for by the VA. MEASURES: Veteran demographic, socioeconomic and clinical factors and use of VA primary care services under the VCP each year. RESULTS: There were 6.3 million Veterans with >54 million VA primary care visits, predominantly (98.5% of visits) at VA facility. The proportion of VA-CCN visits increased in absolute terms from 0.7% in 2015 to 2.6% in 2018. Among Veterans with any VA-CCN primary care, the proportion of VA-CCN visits increased from 22.6% to 55.3%. Logistic regression indicated that Veterans who were female, lived in rural areas, had a driving distance >40 miles, had health insurance or had a psychiatric/depression condition were more likely to receive VA-CCN primary care. Veterans who were older, identified as Black race, required to pay VA copayments, or had a higher Nosos score, were less likely to receive VA-CCN primary care. CONCLUSION: As the VA transitions from the VCP to MISSION and VA facilities gain experience under the new contracts, attention to factors that impact Veterans' use of primary care services in different settings are important to monitor to identify access barriers and to ensure Veterans' health care needs are met.

Clinical characteristics and outcomes of patients with severe left ventricular dysfunction undergoing cardiac MRI viability assessment prior to revascularization.

Coronary artery bypass grafting improves survival in patients with ischemic cardiomyopathy, however, these patients are at high risk for morbidity and mortality. The role of viability testing to guide revascularization in these patients is unclear. Cardiac magnetic resonance imaging (CMR) has not been studied adequately in this population despite being considered a reference standard for infarct imaging. We performed a multicenter retrospective analysis of patients (n = 154) with severe left ventricular systolic dysfunction [ejection fraction (EF) < 35%] on CMR who underwent CMR viability assessment prior to consideration for revascularization. Using the AHA16-segment model, percent total myocardial viability was determined depending on the degree of transmural scar thickness. Patients with or without revascularization had similar clinical characteristics and were prescribed similar medical therapy. Overall, 43% of patients (n = 66) experienced an adverse event during the median 3 years follow up. For the composite outcome (death, myocardial infarction, heart failure hospitalization, stroke, ventricular tachycardia) patients receiving revascularization were less likely to experience an adverse event compared to those without revascularization (HR 0.53, 95% CI 0.33-0.86, p = 0.01). Patients with > 50% viability on CMR had a 47% reduction in composite events when undergoing revascularization opposed to medical therapy alone (HR 0.53, p = 0.02) whereas patients with a viability < 50% were 2.7 times more likely to experience an adverse event (p = 0.01). CMR viability assessment may be an important tool in the shared decision-making process when considering revascularization options in patients with severe ischemic cardiomyopathy.

Evaluation of a Patient-Collected Audio Audit and Feedback Quality Improvement Program on Clinician Attention to Patient Life Context and Health Care Costs in the Veterans Affairs Health Care System.

Importance: Evidence-based care plans can fail when they do not consider relevant patient life circumstances, termed contextual factors, such as a loss of social support or financial hardship. Preventing these contextual errors can reduce obstacles to effective care. Objective: To evaluate the effectiveness of a quality improvement program in which clinicians receive ongoing feedback on their attention to patient contextual factors. Design, Setting, and Participants: In this quality improvement study, patients at 6 Department of Veterans Affairs outpatient facilities audio recorded their primary care visits from May 2017 to May 2019. Encounters were analyzed using the Content Coding for Contextualization of Care (4C) method. A feedback intervention based on the 4C coded analysis was introduced using a stepped wedge design. In the 4C coding schema, clues that patients are struggling with contextual factors are termed contextual red flags (eg, sudden loss of control of a chronic condition), and a positive outcome is prospectively defined for each encounter as a quantifiable improvement of the contextual red flag. Data analysis was performed from May to October 2019. Interventions: Clinicians received feedback at 2 intensity levels on their attention to patient contextual factors and on predefined patient outcomes at 4 to 6 months. Main Outcomes and Measures: Contextual error rates, patient outcomes, and hospitalization rates and costs were measured. Results: The patients (mean age, 62.0 years; 92% male) recorded 4496 encounters with 666 clinicians. At baseline, clinicians addressed 413 of 618 contextual factors in their care plans (67%). After either standard or enhanced feedback, they addressed 1707 of 2367 contextual factors (72%), a significant difference (odds ratio, 1.3; 95% CI, 1.1-1.6; P = .01). In a mixed-effects logistic regression model, contextualized care planning was associated with a greater likelihood of improved outcomes (adjusted odds ratio, 2.5; 95% CI, 1.5-4.1; P < .001). In a budget analysis, estimated savings from avoided hospitalizations were $25.2 million (95% CI, $23.9-$26.6 million), at a cost of $337 242 for the intervention. Conclusions and Relevance: These findings suggest that patient-collected audio recordings of the medical encounter with feedback may enhance clinician attention to contextual factors, improve outcomes, and reduce hospitalizations. In addition, the intervention is associated with substantial cost savings.

Patient Risk Assessment for Transcatheter Aortic Valve Replacement at Veterans Health Administration Hospitals.

OBJECTIVE: To compare patient-level risk assessment at Veterans Affairs (VA) hospitals in patients undergoing transcatheter aortic valve replacement (TAVR) with patients included in the Society for Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy (STS/ACC TVT) registry. METHODS: We retrospectively analyzed the outcomes of veterans with severe aortic stenosis (AS) receiving TAVR from 2012-2016 at eight VA hospitals and compared them with TVT registry outcomes from 2012-2015. Patients were identified via administrative data. Univariable and multivariable Cox proportional hazards models were used to examine 30-day and 1-year all-cause mortality, 30-day and 1-year transient ischemic attack/stroke rates, and permanent pacemaker (PPM) implantation rates. RESULTS: During the study period, a total of 726 veterans underwent TAVR including valve-in-valve procedures (n = 50). Patients were predominantly male (98.2%), with mean age of 78.5 ± 9.3 years; 49.1% were at prohibitive risk and 12.1% were at high risk for surgical aortic valve replacement; 30-day and 1-year all-cause mortality rates were 2.5% and 14.7%, respectively; 30-day and 1-year combined TIA/stroke rates were 6.5% and 13.5%, respectively. In the TVT registry, 15.8% and 37.8% of patients were at prohibitive and high risk, respectively; 30-day and 1-year mortality rates were 5.7% and 22.7%, respectively, and stroke rates were 2.1% and 4.0%, respectively. CONCLUSIONS: This report on TAVR risk assessment within the VA system demonstrates that despite a large proportion of patients classified as prohibitive risk, TAVR was associated with favorable 30-day and 1-year all-cause mortality rates when compared with published outcomes from the STS/ACC TVT registry.

Experiences with the Veterans' Choice Program.

BACKGROUND: To address concerns about Veterans' access to care at US Department of Veterans Affairs (VA) healthcare facilities, the Veterans Access, Choice, and Accountability Act was enacted to facilitate Veterans' access to care in non-VA settings, resulting in the "Veterans Choice Program" (VCP). OBJECTIVES: To assess the characteristics of Veterans who used or planned to use the VCP, reasons for using or planning to use the VCP, and experiences with the VCP. DESIGN: Mixed-methods. SUBJECTS: After sampling Veterans in the Midwest census region receiving care at VA healthcare facilities, we included 4521 Veterans in the analyses. Of these, 60 Veterans participated in semi-structured qualitative interviews. APPROACH: Quantitative data were derived from VA's administrative and clinical data and a survey of Veterans including Veteran characteristics and self-reported use of VCP. Associations between Veterans' characteristics and use or planned use of the VCP were assessed using logistic regression analysis. Interview data were analyzed using thematic analysis. KEY RESULTS: Veterans with a higher odds of reporting use or intended use of the VCP were women, lived further distances from VA facilities, or had worse health status than other Veterans (P ≤ 0.01). Key themes included positive experiences with the VCP (timeliness of care, location of care, access to services, scheduling improvements, and coverage of services), and negative experiences with the VCP (complicated scheduling processes, inconveniently located appointments, delays securing appointments, billing confusion, and communication breakdowns). DISCUSSION: Our findings suggest that Veterans value access to care close to their home and care that addresses the needs of women and Veterans with poor health status. The Mission Act was passed in June 2018 to restructure the VCP and consolidate community care into a single program, continuing VA's commitment to support access to community care into the future.

Healthcare Utilization and Costs for Patients With Parkinson's Disease After Deep Brain Stimulation.

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.

Alerting Doctors About Patient Life Challenges: A Randomized Control Trial of a Previsit Inventory of Contextual Factors.

Objective. Effective care attends to relevant patient life context. We tested whether a patient-completed inventory helps providers contextualize care and increases patients' perception of patient-centered care (PCC). Method. The inventory listed six red flags (e.g., emergency room visits) and if the patient checked any, prompted for related contextual factors (e.g., transportation difficulties). Patients were randomized to complete the inventory or watch health videos prior to their visit. Patients presented their inventory results to providers during audio-recorded encounters. Audios were coded for physician probing and incorporating context in care plans. Patients completed the Consultation and Relational Empathy (CARE) instrument after the encounter. Results. A total of 272 Veterans were randomized. Adjusting for covariates and clustering within providers, inventory patients rated visits as more patient-centered (44.5; standard error = 1.1) than controls (42.7, standard error = 1.1, P = 0.04, CARE range = 10-50). Providers were more likely to probe red flags (odds ratio = 1.54; confidence interval = 1.07-2.22; P = 0.02) when receiving the inventory, but not incorporating context into care planning. Conclusion. A previsit inventory of life context increased perceptions of PCC and providers' likelihood of exploring context but not contextualizing care. Information about patients' life challenges is not sufficient to assure that context informs provider decision making even when provided at the point of care by patients themselves.

Influence of drug class and healthcare setting on systemic antifungal expenditures in the United States, 2005-15.

PURPOSE: Overall and specific class trends in systemic antifungal expenditures in various U.S. healthcare settings from 2005 through 2015 were evaluated. METHODS: Systemic antifungal expenditures from January 1, 2005, through December 31, 2015, were obtained from the QuintilesIMS National Sales Perspective database, which provides a statistically valid projection of medication purchases from multiple markets throughout the United States. Summary data for total antifungal expenditures over the entire period are reported, as are growth and the percentage change in expenditures from one year to the next. Expenditures were also assessed specifically by year, class, and healthcare setting. Expenditure trends over the study period were assessed using simple linear trend regression models. RESULTS: Overall expenditures for the 11-year period were $9.37 billion. The greatest proportion of expenditures occurred in nonfederal hospitals (47.2%) and for triazoles (57.6%). From 2005 through 2015, total expenditures decreased from $1.1 billion to $894 million (-18.8%, p = 0.09); however, expenditures in clinics and retail pharmacies increased (202%, p < 0.01, and 13.8%, p = 0.04, respectively), a trend most pronounced after 2012. Expenditures for flucytosine also increased (968.1%, p < 0.01), particularly in clinics where there was a dramatic 6,640.9% increase (p < 0.01). CONCLUSION: From 2005 through 2015, an increase in systemic antifungal expenditures was observed in community settings, despite an overall decrease in total antifungal expenditures in the United States. Large increases in flucytosine expenditures were observed, particularly in the community.

Cost of deep brain stimulation for the treatment of Parkinson's disease by surgical stimulation sites.

OBJECTIVE: To assess costs and effectiveness of deep brain stimulation (DBS) of the internal globus pallidum (GPi) versus subthalamic nucleus (STN) from the provider and societal perspectives for Parkinson's disease (PD) patients in a multicenter randomized trial. METHODS: All costs from randomization to 36 months were included. Costs were from Department of Veterans Affairs (VA) and Medicare databases and clinical trial data. Quality adjusted life years (QALYs) were from Quality of Well Being questionnaires. RESULTS: Provider costs were similar for the 144 GPi and 130 STN patients (GPi: $138,044 vs. STN: $131,822; difference = $6,222, 95% confidence interval [CI]: -$42,125 to $45,343). Societal costs were also similar (GPi: $171,061 vs. STN: $167,706; difference = $3,356, 95% CI: -$57,371 to $60,294). The GPi patients had nonsignificantly more QALYs. CONCLUSIONS: The QALYs and costs were similar; the level of uncertainty given the sample size suggests that these factors should not direct treatment or resource allocation decisions in selecting or making available either procedure for eligible PD patients.

Improving the quality of telephone-delivered health care: a national quality improvement transformation initiative.

BACKGROUND: Many Veterans Affairs (VA) primary care (PC) patients prefer telephone-delivered care to other health care delivery modalities. OBJECTIVE: To evaluate PC patients' telephone experiences and outcomes before and after a national telephone transformation quality improvement (QI) collaborative. METHODS: Cross-sectional surveys were conducted pre- and post-collaborative. We used bivariate analyses to assess differences in pre/post outcomes and multivariate regression to identify variables associated with patients' perceptions of poor quality care. RESULTS: Patients from 13 VA facilities participated (n = 730; pre-intervention = 314, post-intervention = 416); most of them were males (90%) with a mean age of 62 years. After the collaborative (versus pre-collaborative), few experienced transfers (52% versus 62%, P = 0.0006) and most reported timely call answer (88% versus 80%, P = 0.003). Improvements in staff understanding why patients were calling and providing needed medical information were also found. There were measurable improvements in patient satisfaction (87% versus 82% very/mostly satisfied, P = 0.04) and perceived quality of telephone care (85% versus 78% excellent/good quality, P = 0.01) post- collaborative. The proportion of veterans who reported delayed care due to telephone access issues decreased from 41% to 15% after the collaborative, P < 0.0001. Perceptions of poor quality care were higher when calls were for urgent care needs did not result in receipt of needed information and included a transfer or untimely answer. CONCLUSIONS: The QI collaborative led to improvements in timeliness of answering calls, patient satisfaction and perceptions of high-quality telephone care and fewer reports of health care delays. Barriers to optimal telephone care 'quality' include untimely answer, transfers, non-receipt of needed information and urgent care needs.

Medication acquisition across systems of care and patient-provider communication among older veterans.

PURPOSE: The results of a survey assessing Medicare Part D enrollment, the use of pharmacotherapies for chronic diseases, and other medication-use issues in a population of elderly military veterans are presented. METHODS: Medicare-eligible (i.e., ≥65 years of age) patients with documented recent service use at a single Veterans Affairs (VA) medical center were targeted for a mail survey. Women were oversampled (20%) to ensure an adequate sample size; the sample was weighted to adjust for this oversampling. Usable survey data were received from 458 survey respondents. RESULTS: Nearly all respondents (93.2%) reported having one or more chronic conditions; of those, 93.3% reported regular use of multiple drug therapies, and 30.1% reported using medications prescribed by both VA and non-VA providers for the same chronic condition. About half of the survey respondents reported at least one office visit with a non-VA physician during the previous year, and 55.8% reported obtaining medications from non-VA pharmacies. More than half (54.1%) of the respondents reported non-VA medication coverage, with 21.2% indicating they were enrolled in Medicare Part D. Among the respondents who reported obtaining medications from non-VA pharmacies, substantial proportions reported discussing those medications with VA physicians never (38.4%) or infrequently (15.7%). CONCLUSION: Although large proportions of Medicare-eligible veterans take multiple medications and use non-VA health care services and pharmacies, many do not discuss medications obtained outside the VA system with VA physicians, suggesting that increased efforts to enhance provider-patient communication and medication reconciliation across VA and non-VA systems of care may be warranted.

Unannounced standardized patient assessment of the roter interaction analysis system: the challenge of measuring patient-centered communication.

BACKGROUND: Despite wide-spread endorsement of patient-centered communication (PCC) in health care, there has been little evidence that it leads to positive change in health outcomes. The lack of correlation may be due either to an overestimation of the value of PCC or to a measurement problem. If PCC measures do not capture elements of the interaction that determine whether the resulting care plan is patient-centered, they will confound efforts to link PCC to outcomes. OBJECTIVE: To evaluate whether one widely used measure of PCC, the Roter Interaction Analysis System (RIAS), captures patient-centered care planning. DESIGN: RIAS was employed in the coding of unannounced standardized patient (USP) encounters that were scripted so that the failure to address patient contextual factors would result in an ineffective plan of care. The design enabled an assessment of whether RIAS can differentiate between communication behavior that does and does not result in a care plan that takes into account a patient's circumstances and needs. PARTICIPANTS: Eight actors role playing four scripted cases (one African American and one Caucasian for each case) in 399 visits to 111 internal medicine attending physicians. MAIN MEASURES: RIAS measures included composites for physician utterance types and (in separate models) two different previously applied RIAS patient-centeredness summary composites. The gold standard comparison measure was whether the physician's treatment plan, as abstracted from the visit note, successfully addressed the patient's problem. Mixed effects regression models were used to evaluate the relationship between RIAS measures and USP measured performance, controlling for a variety of design features. KEY RESULTS: None of the RIAS measures of PCC differentiated encounters in which care planning was patient-centered from care planning in which it was not. CONCLUSIONS: RIAS, which codes each utterance during a visit into mutually exclusive and exhaustive categories, does not differentiate between conversations leading to and not leading to care plans that accommodate patients' circumstances and needs.

Parkinson's disease medication use and costs following deep brain stimulation.

The costs of treating Parkinson's disease (PD) are significant. Medication reductions usually occur following deep brain stimulation (DBS), but less is known about the relative costs of DBS targets, the globus pallidum (GPi) or the subthalamic nucleus (STN). This article reports medication costs between best medical therapy (BMT) and DBS over 6 months postintervention and by DBS target over 36 months postsurgery. Prescription use and costs for patients (n = 161) with advanced PD from a multisite randomized trial of BMT and DBS were examined overall and by drug category. Medication adjustment occurred at the discretion of the neurologists. PD medications were extracted from the Department of Veterans Affairs Decision Support System database. Levodopa equivalents (LEDD) were significantly lower for DBS than for BMT patients at 6 months (1101 vs 1398 mg; P = .005), but costs were similar (US$1750 vs US$1589; P = .55). LEDD decreased following GPi and STN DBS (1395-1161 mg, P = .014; and 1347-891 mg, P < .0001, respectively) in the first 6 months, but was lower for STN than for GPi over 36 months following DBS (P = .03). Total PD medication costs per 6-month intervals decreased over 36 months (P < .0001), but did not differ by target (P = .50) in the mixed-model analysis. However, cumulative medication costs over 36 months were lower for the STN than for GPi patients. PD medication use and costs decreased following DBS in either target over 36 months, but cumulative costs were less for STN than for GPi.

Participant Retention in the Veterans Health Administration's MOVE! Weight management program, 2010.

INTRODUCTION: Participant retention is a frequent concern in structured weight-management programs. Although research has explored participant characteristics influencing retention, little attention has been given to the influence of program characteristics. The objective of this study was to examine how program characteristics relate to participant retention in the Veterans Health Administration's weight-management program, MOVE! METHODS: We conducted semistructured interviews with coordinators of 12 MOVE! programs located throughout the United States, 5 with high participant retention rates and 7 with low rates. We transcribed and descriptively coded interviews and compared responses from high- and low-retention programs. RESULTS: Characteristics related to retention were provider knowledge of and referral to the program, reputation of the program within the medical facility, the MOVE! meeting schedule, inclusion of physical activity in group meetings, and involvement of the MOVE! physician champion. MOVE! introductory sessions, frequency of group meetings, and meeting topics were not related to retention. Coordinators described efforts to improve retention, including participant contracts and team competitions. Coordinators at 5 high-retention facilities and 1 low-retention facility discussed efforts to improve retention. CONCLUSION: Coordinators identified important program characteristics that could guide improvements to retention in group-based weight-management programs. Training for providers is needed to assist with referral decisions, and program planners should consider incorporating physical activity in group meetings.

Uncharted territory: measuring costs of diagnostic errors outside the medical record.

CONTEXT: In a past study using unannounced standardised patients (USPs), substantial rates of diagnostic and treatment errors were documented among internists. Because the authors know the correct disposition of these encounters and obtained the physicians' notes, they can identify necessary treatment that was not provided and unnecessary treatment. They can also discern which errors can be identified exclusively from a review of the medical records. OBJECTIVE: To estimate the avoidable direct costs incurred by physicians making errors in our previous study. DESIGN: In the study, USPs visited 111 internal medicine attending physicians. They presented variants of four previously validated cases that jointly manipulate the presence or absence of contextual and biomedical factors that could lead to errors in management if overlooked. For example, in a patient with worsening asthma symptoms, a complicating biomedical factor was the presence of reflux disease and a complicating contextual factor was inability to afford the currently prescribed inhaler. Costs of missed or unnecessary services were computed using Medicare cost-based reimbursement data. SETTING: Fourteen practice locations, including two academic clinics, two community-based primary care networks with multiple sites, a core safety net provider, and three Veteran Administration government facilities. MAIN OUTCOME MEASURES: Contribution of errors to costs of care. RESULTS: Overall, errors in care resulted in predicted costs of approximately $174,000 across 399 visits, of which only $8745 was discernible from a review of the medical records alone (without knowledge of the correct diagnoses). The median cost of error per visit with an incorrect care plan differed by case and by presentation variant within case. CONCLUSIONS: Chart reviews alone underestimate costs of care because they typically reflect appropriate treatment decisions conditional on (potentially erroneous) diagnoses. Important information about patient context is often entirely missing from medical records. Experimental methods, including the use of USPs, reveal the substantial costs of these errors.

Optimizing primary care telephone access and patient satisfaction.

Telephone medicine is often preferred by patients to meet primary care needs and may be associated with high patient satisfaction. This article presents findings about incoming patient calls to primary care for medically based reasons during office hours and reports factors independently associated with telephone encounter satisfaction, considering patient characteristics, call reasons, and staff responsiveness, for a national cohort of primary care users. Interviews were conducted with patients from 18 nationwide primary care clinics during the fall of 2009. Calling for an urgent medical issue was associated with dissatisfaction. Odds of call satisfaction were greater when patients thought staff was friendly (10×), call answer was timely (5×), and needed medical information was provided (7×). These findings can be used for interventions to optimize telephone access and patient satisfaction which is beneficial because satisfactory telephone encounters reduce primary care use and satisfied patients are more likely to be engaged in their health care.
