Variability and Costs of Low-Value Preoperative Testing for Cataract Surgery Within the Veterans Health Administration.

Importance: The Choosing Wisely guidelines indicate that preoperative testing is often unnecessary and wasteful for patients undergoing cataract operations. However, little is known about the impact of these widely disseminated guidelines within the US Veterans Health Administration (VHA) system. Objective: To examine the extent, variability, associated factors, and costs of low-value tests (LVTs) prior to cataract operations in the VHA. Design, Setting, and Participants: This cohort study examined records of all patients receiving cataract operations within the VHA in fiscal year 2017 (October 1, 2016, to September 31, 2017). Records from 135 facilities nationwide supporting both ambulatory and inpatient surgery were included. Exposures: A laboratory test occurring within 30 days prior to cataract surgery and within 30 days after clinic evaluation. Main Outcomes and Measures: Overall national and facility-level rates and associated costs of receiving any of 8 common LVTs in the 30 days prior to cataract surgery. The patient characteristics, procedure type, and facility-level factors associated with receiving at least 1 test, the number of tests received, and receipt of a bundle of 4 tests (complete blood count, basic metabolic profile, chest radiograph, and electrocardiogram). Results: A total of 69 070 cataract procedures were identified among 50 106 patients (66 282 [96.0%] men; mean [SD] age, 71.7 [8.1] years; 53 837 [77.9%] White, 10 292 [14.9%] Black). Most of the patient population had either overweight (23 292 [33.7%] patients) or obesity (27 799 [40.2%] patients). Approximately 49% of surgical procedures (33 424 procedures) were preceded by 1 or more LVT with an overall LVT cost of $2 597 623. Among patients receiving LVTs, electrocardiography (7434 patients [29.9%]) was the most common, with some patients also receiving more costly tests, including chest radiographs (489 patients [8.2%]) and pulmonary function tests (127 patients [3.4%]). For receipt of any LVT, the intraclass correlation coefficient was 0.61 (P < .001) at the facility level and 0.06 (P < .001) at the surgeon level, indicating the substantial contribution of the facility to amount of tests given. Conclusions and Relevance: Despite existing guidelines, use of LVTs prior to cataract surgery is both common and costly within a large, national integrated health care system. Our results suggest that publishing evidence-based guidelines alone-such as the Choosing Wisely campaign-may not sufficiently influence individual physician behavior, and that system-level efforts to directly deimplement LVTs may therefore necessary to effect sustained change.

The State of Men's Health Services in the Veterans Health Administration.

PURPOSE OF REVIEW: For many diseases that place a large burden on our health care system, men often have worse health outcomes than women. As the largest single provider of health care to men in the USA, the Veterans Health Administration (VA) has the potential to serve as leader in the delivery of improved men's health care to address these disparities. RECENT FINDINGS: The VA system has made recent strides in improving benefits for aspects of men's health that are traditionally poorly covered, such as treatment for male factor infertility. Despite this, review of Quality Enhancement Research Initiatives (QUERIs) within the VA system reveals few efforts to integrate disparate areas of care into a holistic men's health program. Policies to unify currently disparate aspects of men's health care will ensure that the VA remains a progressive model for other health care systems in the USA.

Predictors of Use of Monitored Anesthesia Care for Outpatient Gastrointestinal Endoscopy in a Capitated Payment System.

BACKGROUND & AIMS: Use of monitored anesthesia care (MAC) for gastrointestinal endoscopy has increased in the Veterans Health Administration (VHA) as in fee-for-service environments, despite the absence of financial incentives. We investigated factors associated with use of MAC in an integrated health care delivery system with a capitated payment model. METHODS: We performed a retrospective cohort study using multilevel logistic regression, with MAC use modeled as a function of procedure year, patient- and provider-level factors, and facility effects. We collected data from 2,091,590 veterans who underwent outpatient esophagogastroduodenoscopy and/or colonoscopy during fiscal years 2000-2013 at 133 facilities. RESULTS: The adjusted rate of MAC use in the VHA increased 17% per year (odds ratio for increase, 1.17; 95% confidence interval, 1.09-1.27) from fiscal year 2000 through 2013. The most rapid increase occurred starting in 2011. VHA use of MAC was associated with patient-level factors that included obesity, obstructive sleep apnea, higher comorbidity, and use of prescription opioids and/or benzodiazepines, although the magnitude of these effects was small. Provider-level and facility factors were also associated with use of MAC, although again the magnitude of these associations was small. Unmeasured facility-level effects had the greatest effect on the trend of MAC use. CONCLUSIONS: In a retrospective study of veterans who underwent outpatient esophagogastroduodenoscopy and/or colonoscopy from fiscal year 2000 through 2013, we found that even in a capitated system, patient factors are only weakly associated with use of MAC. Facility-level effects are the most prominent factor influencing increasing use of MAC. Future studies should focus on better defining the role of MAC and facility and organizational factors that affect choice of endoscopic sedation. It will also be important to align resources and incentives to promote appropriate allocation of MAC based on clinically meaningful patient factors.

Multimorbidity and healthcare utilisation among high-cost patients in the US Veterans Affairs Health Care System.

OBJECTIVES: To investigate the relationship between multimorbidity and healthcare utilisation patterns among the highest cost patients in a large, integrated healthcare system. DESIGN: In this retrospective cross-sectional study of all patients in the U.S. Veterans Affairs (VA) Health Care System, we aggregated costs of individuals' outpatient and inpatient care, pharmacy services and VA-sponsored contract care received in 2010. We assessed chronic condition prevalence, multimorbidity as measured by comorbidity count, and multisystem multimorbidity (number of body systems affected by chronic conditions) among the 5% highest cost patients. Using multivariate regression, we examined the association between multimorbidity and healthcare utilisation and costs, adjusting for age, sex, race/ethnicity, marital status, homelessness and health insurance status. SETTING: USA VA Health Care System. PARTICIPANTS: 5.2 million VA patients. MEASURES: Annual total costs; absolute and share of costs generated through outpatient, inpatient, pharmacy and VA-sponsored contract care; number of visits to primary, specialty and mental healthcare; number of emergency department visits and hospitalisations. RESULTS: The 5% highest cost patients (n=261,699) accounted for 47% of total VA costs. Approximately two-thirds of these patients had chronic conditions affecting ≥3 body systems. Patients with cancer and schizophrenia were less likely to have documented comorbid conditions than other high-cost patients. Multimorbidity was generally associated with greater outpatient and inpatient utilisation. However, increased multisystem multimorbidity was associated with a higher outpatient share of total costs (1.6 percentage points per affected body system, p<0.01) but a lower inpatient share of total costs (-0.6 percentage points per affected body system, p<0.01). CONCLUSIONS: Multisystem multimorbidity is common among high-cost VA patients. While some patients might benefit from disease-specific programmes, for most patients with multimorbidity there is a need for interventions that coordinate and maximise efficiency of outpatient services across multiple conditions.

Cost-Effectiveness Analysis of Adjuvant Stage III Colon Cancer Treatment at Veterans Affairs Medical Centers.

The objective of this study was to evaluate the real-world cost effectiveness of adjuvant stage III colon cancer chemotherapy regimens, given that previous analyses have been based on data from clinical trials. The study was designed using integrated decision tree and Markov model, which was developed to evaluate the cost effectiveness of 5-fluorouracil/leucovorin (5-FU/LV), capecitabine, and the combination of each with oxaliplatin. The analysis was performed from a US Veterans Affairs perspective via retrospectively collected data, over a 5-year model time horizon. Outcome and cost data were used to calculate cost per quality adjusted life year (QALY), and one-way and probabilistic sensitivity analyses were performed. In the base case analysis, capecitabine and capecitabine plus oxaliplatin both cost more and were less effective than other regimens, and 5-FU/LV plus oxaliplatin, compared to 5-FU/LV alone, resulted in a cost of $25,997 per QALY gained. Model results were generally robust to parameter variation. Capecitabine plus oxaliplatin could be economically reasonable if full dosing occurred ≥76% of the time (base case 42%). In a real-world setting, the addition of oxaliplatin to 5-FU/LV is more effective but also more costly than 5-FU/LV alone. If full dosing of capecitabine-containing regimens can be assured, they may also be cost-effective strategies.

Cost-effectiveness of integrated care for elderly depressed patients in the PRISM-E study.

BACKGROUND: One proposed strategy to improve outcomes associated with depression and other behavioral health disorders in primary care settings is to strengthen collaboration between primary care and specialty mental health care through integrated care (IC). AIMS: We compare the cost-effectiveness of IC in primary care to enhanced specialty referral (ESR) for elders with behavioral health disorders from the Primary Care Research in Substance Abuse and Mental Health study, which was a randomized trial conducted between 2000 and 2002, using a societal perspective. METHODS: The IC model had a behavioral health professional co-located in the primary care setting, and the primary care provider continued involvement in the mental health/substance abuse care of the patient. The comparison model, enhanced specialty referral (ESR), required referral to a behavioral health provider outside the primary care setting, and the behavioral health provider had primary responsibility for the mental health/substance abuse needs of the patient. Costs and clinical outcomes for 840 elders with depression were analyzed using incremental cost-effectiveness ratios, the net benefits framework, cost-effectiveness planes, and acceptability curves. Outcomes were measured by the Center for Epidemiologic Studies Depression Scale (CES-D) and converted to depression-free days and Quality Adjusted Life Years (QALY). A variation on depression free days was proposed as an improvement on current methods. Separate analyses were conducted for Veteran's Affairs (n=365; n=175 in IC and n=190 in ESR) and non-Veteran's Affairs (n=475; n=242 in IC and n=233 in ESR) settings. RESULTS: ESR participants in the non-VA sample exhibited lower average CES-D scores (i.e., an improvement in depressive symptoms) than did IC participants (beta = 2.8, p < 0.01), no such difference was noted in the VA sample (p > 0.05). Mean costs were $D6,338 for VA IC participants; $7,007 for VA ESR participants; $3,657 for non-VA IC participants; and $3,673 for non-VA ESR participants. Although the cost-effectiveness planes suggest some uncertainty about the cost-effectiveness of the intervention, more than 75% of the bootstrap draws were considered cost-effective due to a decrease in total costs for IC in the full Veteran's Affairs sample. DISCUSSION: The findings indicate that IC is likely to be a cost-effective intervention in contrast with ESR in the Veteran's Affairs setting. In the non-Veteran's Affairs settings, IC is not a more cost-effective intervention in comparison with ESR. In the VA setting, the greater clinical improvement associated with IC coupled with the variation in costs and outcomes were such that IC was determined to be more cost-effective than ESR with a probability of 73-80%. Among non-VA participants, the lower clinical outcomes combined with no discernable differences in costs translated with a low probability that IC was more cost-effective than ESR, at any of the estimated values of clinical improvements. This suggests the importance of clinical setting in determining the clinical and cost effectiveness of IC for mental health. LIMITATIONS: Our analyses were restricted to a six-month period, based on self-report, and did not include societal costs related to lost productivity and future costs. IMPLICATIONS: These results suggest that general integration has its advantages and, when such integration exists, further integrating behavioral health care into primary care might be considered as one way to improve depression in elders. The finding that ESR may be cost effective in some settings is also policy relevant. Further research is needed to analyze the components of the costs of ESR in non-VA settings and the effectiveness of IC in VA settings.

Research in the Veterans Health Administration: the report of the Research Realignment Advisory Committee.

In 1995 the Under Secretary for Health of the Department of Veterans Affairs constituted the Research Realignment Advisory Committee and charged it with reviewing the VA's research program. After meeting in 1995 and 1996, the committee identified 12 findings, which fall into four broad categories: allocation of research resources among VA research programs, acquisition and protection of resources, stability and maintenance of infrastructure, and outreach and communications. The most far-reaching recommendation was to establish designated research areas so that VA research could be focused more sharply on the specific needs of veterans while maintaining a research base for relatively less common conditions and needs integral to the VA's mission. The second major issue was that research funding should be increased (because it had fallen in inflation-adjusted dollars while the cost of doing research continued to rise). The third major area dealt with operational issues about how research was administered in the newly created system of geographically defined "veterans integrated service networks" and at the medical centers and how research monies flowed to medical centers. The final major area had to do with career development, for the committee considered the recruitment and retention of outstanding junior investigators to be a core function of VA research. The committee's recommendations, some of which have already been implemented, form the basis for strengthening the VA's research enterprise and for fully integrating it within the new structure of health care delivery in the VA.
