Cost analysis of a coaching intervention to increase use of transradial percutaneous coronary intervention.

BACKGROUND: The transradial approach (TRA) to cardiac catheterization is safer than the traditional transfemoral approach (TFA), with similar clinical effectiveness. However, adoption of TRA remains low, representing less than 50% of catheterization procedures in 2015. Peer coaching is one approach to facilitate implementation; however, the costs of this strategy for cardiac procedures such as TRA are unclear. METHODS: We conducted an activity-based costing analysis (ABC) of a multi-center, hybrid type III implementation trial of a coaching intervention designed to increase the use of TRA. We identified the key activities of the intervention and determined the personnel, resources, and time needed to complete each activity. The personnel cost per hour and the activity duration were then used to estimate the cost of each activity and the total variable cost of the implementation. Fixed costs related to designing and running the implementation were calculated separately. All costs are reported in 2019 constant US dollars. RESULTS: The total cost of the coaching intervention implementation was $374,863. Of the total cost, $367,752 were variable costs due to travel, preparatory work, in-person coaching, post-intervention evaluation, and administrative time. We estimated fixed costs of $7112. The mean marginal cost of implementing the intervention at only one additional medical center was $52,536. CONCLUSIONS: We provide granular cost estimates of a conceptually rooted implementation strategy designed to increase the uptake of TRA for cardiac catheterization. We estimate that implementation costs stemming from the coaching approach would be offset after the conversion of approximately 409 to 1363 catheterizations from TFA to TRA. Our estimates provide benchmarks of the expected costs of implementing evidence-based, but expertise-intensive, cardiac procedures. TRIAL REGISTRATION: ISRCTN, ISRCTN66341299 .

Comparable, but distinct: Perceptions of primary care provided by physicians and nurse practitioners in full and restricted practice authority states.

AIMS: To understand patients' and providers' perceptions of primary care delivered by nurse practitioners (NPs) in the Veterans Affairs Healthcare System. DESIGN: Qualitative exploratory study (in convergent mixed-methods design). METHODS: Semi-structured interviews in 2016 with primary care providers and patients from facilities in states with full and restricted practice authority for NPs. Patient sample based on reassignment to: (a) a NP; or (b) a different physician following an established physician relationship. Data were analysed using content analysis. RESULTS: We interviewed 28 patients, 17 physicians and 14 NPs. We found: (a) NPs provided more holistic care than physicians; (b) patients were satisfied with NPs; and (c) providers' professional experience outweighed provider type. CONCLUSIONS: Patients' preferences for NPs (compared with prior physicians) contributed to perceptions of patient centredness. Similarities in providers' perceptions suggest NPs and physicians are both viable providers for primary care. IMPACT: Nurse Practitioners (NPs): practice authority Veterans Affairs Health care: nurse practitioners will continue to be a viable resource for primary care delivery United States Health care: challenges notions patients may not be satisfied with care provided by NPs and supports expanding their use to provide much-needed access to primary care services; expanding Full Practice Authority would allow states to provide acceptable primary care without diminishing patient or provider experiences.

Outcomes of primary care delivery by nurse practitioners: Utilization, cost, and quality of care.

OBJECTIVE: To examine whether nurse practitioner (NP)-assigned patients exhibited differences in utilization, costs, and clinical outcomes compared to medical doctor (MD)-assigned patients. DATA SOURCES: Veterans Affairs (VA) administrative data capturing characteristics, outcomes, and provider assignments of 806 434 VA patients assigned to an MD primary care provider (PCP) who left VA practice between 2010 and 2012. STUDY DESIGN: We applied a difference-in-difference approach comparing outcomes between patients reassigned to MD and NP PCPs, respectively. We examined measures of outpatient (primary care, specialty care, and mental health) and inpatient (total and ambulatory care sensitive hospitalizations) utilization, costs (outpatient, inpatient and total), and clinical outcomes (control of hemoglobin A1c, LDL, and blood pressure) in the year following reassignment. PRINCIPAL FINDINGS: Compared to MD-assigned patients, NP-assigned patients were less likely to use primary care and specialty care services and incurred fewer total and ambulatory care sensitive hospitalizations. Differences in costs, clinical outcomes, and receipt of diagnostic tests between groups were not statistically significant. CONCLUSIONS: Patients reassigned to NPs experienced similar outcomes and incurred less utilization at comparable cost relative to MD patients. NPs may offer a cost-effective approach to addressing anticipated shortages of primary care physicians.

Accessing Care Through the Veterans Choice Program: The Veteran Experience.

BACKGROUND: The Veterans Choice Program (VCP) was implemented to improve healthcare access by expanding healthcare options for Veterans Health Administration (VHA) enrollees. OBJECTIVES: To understand Veterans' experience accessing VCP care. DESIGN: Qualitative content analysis. SUBJECTS: Forty-seven veterans from three medical centers in three of the five VA geographical regions. APPROACH: We used semi-structured telephone interviews designed to elicit descriptions of Veterans' experiences. Data was analyzed using iterative, inductive, and deductive content analysis. Broad themes were identified based on representative interview responses. KEY RESULTS: We identified six themes: general impressions (concept and frustration); preferred source of care (institution, specialty, and individual provider); facilitators (VA staff facilitation and proactive Veterans); barriers (complexity, lack of responsiveness, lack of local providers, and poor coordination); perceived sources of VCP problems (learning curve, leadership and staff, and politics); and unintended negative impact (responsibility for costs of care and discontinued access to community care). DISCUSSION: Most Veterans who had received care through the VCP felt that it improved their access to care. However, accessing care through the VCP is a complex process that requires proactive Veterans and active support from the VA, third-party administrators, and availability of participating community providers. Veterans' abilities to navigate this process and the level of support provided varied widely. Even patients who did receive care through VCP found the process challenging. Greater support is needed for some Veterans to successfully access VCP care because Veterans who need care the most may be the least able to access it.

Methods for Measuring Racial Differences in Hospitals Outcomes Attributable to Disparities in Use of High-Quality Hospital Care.

OBJECTIVE: To compare two approaches to measuring racial/ethnic disparities in the use of high-quality hospitals. DATA SOURCES: Simulated data. STUDY DESIGN: Through simulations, we compared the "minority-serving" approach of assessing differences in risk-adjusted outcomes at minority-serving and non-minority-serving hospitals with a "fixed-effect" approach that estimated the reduction in adverse outcomes if the distribution of minority and white patients across hospitals was the same. We evaluated each method's ability to detect and measure a disparity in outcomes caused by minority patients receiving care at poor-quality hospitals, which we label a "between-hospital" disparity, and to reject it when the disparity in outcomes was caused by factors other than hospital quality. PRINCIPAL FINDINGS: The minority-serving and fixed-effect approaches correctly identified between-hospital disparities in quality when they existed and rejected them when racial differences in outcomes were caused by other disparities; however, the fixed-effect approach has many advantages. It does not require an ad hoc definition of a minority-serving hospital, and it estimated the magnitude of the disparity accurately, while the minority-serving approach underestimated the disparity by 35-46 percent. CONCLUSIONS: Researchers should consider using the fixed-effect approach for measuring disparities in use of high-quality hospital care by vulnerable populations.

Weekend Discharges and Length of Stay Among Veterans Admitted for Chronic Obstructive Pulmonary Disease.

BACKGROUND: Discharge rates are substantially lower on weekends, though the impact on hospital length of stay (LOS) is not fully understood. OBJECTIVES: The primary objective was to examine the association of weekend discharges with hospital LOS. We also examined the association of weekend discharges with readmission, mortality, and postdischarge follow-up. RESEARCH DESIGN AND METHODS: A cohort study of 25,301 patients who were admitted to Veterans Affairs hospitals for chronic obstructive pulmonary disease during October 01, 2008-September 30, 2010, including 3845 patients discharged on the weekend (Saturday or Sunday) and 21,456 discharged on weekdays (Monday through Friday). RESULTS: There were significantly fewer discharges on the weekend (1922 per weekend day vs. 4279 per weekday, P<0.01). Inpatient status during the weekend at any point in hospitalization was associated with an increased LOS of 0.59 day [95% confidence interval (CI), 0.54-0.63 d]. Discharge on the weekend was not associated with increased odds of 30-day hospital readmission [odds ratio (OR)=1.00; 95% CI, 0.90-1.10] or lack of primary care follow-up visit within 14 days of discharge (OR=0.94; 95% CI, 0.85-1.03). However, weekend discharges were significantly associated with lower odds of mortality within 30 days after discharge (OR=0.80; 95% CI, 0.65-0.99). CONCLUSIONS: The presence of fewer weekend discharges was associated with significantly longer hospital lengths of stay. Weekend discharges were not associated with higher readmission rates and had lower rates of mortality compared with weekdays discharges. Identifying methods to increase weekend discharges may create an opportunity to improve hospital efficiency.

Trends in Timing of Dialysis Initiation within Versus Outside the Department of Veterans Affairs.

BACKGROUND AND OBJECTIVES: The secular trend toward dialysis initiation at progressively higher levels of eGFR is not well understood. This study compared temporal trends in eGFR at dialysis initiation within versus outside the Department of Veterans Affairs (VA)-the largest non-fee-for-service health system in the United States. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The study used linked data from the US Renal Data System, VA, and Medicare to compare temporal trends in eGFR at dialysis initiation between 2000 and 2009 (n=971,543). Veterans who initiated dialysis within the VA were compared with three groups who initiated dialysis outside the VA: (1) veterans whose dialysis was paid for by the VA, (2) veterans whose dialysis was not paid for by the VA, and (3) nonveterans. Logistic regression was used to estimate average predicted probabilities of dialysis initiation at an eGFR≥10 ml/min per 1.73 m(2). RESULTS: The adjusted probability of starting dialysis at an eGFR≥10 ml/min per 1.73 m(2) increased over time for all groups but was lower for veterans who started dialysis within the VA (0.31; 95% confidence interval [95% CI], 0.30 to 0.32) than for those starting outside the VA, including veterans whose dialysis was (0.36; 95% CI, 0.35 to 0.38) and was not (0.40; 95% CI, 0.40 to 0.40) paid for by the VA and nonveterans (0.39; 95% CI, 0.39 to 0.39). Differences in eGFR at initiation within versus outside the VA were most pronounced among older patients (P for interaction <0.001) and those with a higher risk of 1-year mortality (P for interaction <0.001). CONCLUSIONS: Temporal trends in eGFR at dialysis initiation within the VA mirrored those in the wider United States dialysis population, but eGFR at initiation was consistently lowest among those who initiated within the VA. Differences in eGFR at initiation within versus outside the VA were especially pronounced in older patients and those with higher 1-year mortality risk.
