Cost-effectiveness of a nurse practitioner-family physician model of care in a nursing home: controlled before and after study.

AIMS: To examine the cost-effectiveness of a nurse practitioner-family physician model of care compared with family physician-only care in a Canadian nursing home. BACKGROUND: As demand for long-term care increases, alternative care models including nurse practitioners are being explored. DESIGN: Cost-effectiveness analysis using a controlled before-after design. METHODS: The study included an 18-month 'before' period (2005-2006) and a 21-month 'after' time period (2007-2009). Data were abstracted from charts from 2008-2010. We calculated incremental cost-effectiveness ratios comparing the intervention (nurse practitioner-family physician model; n = 45) to internal (n = 65), external (n = 70) and combined internal/external family physician-only control groups, measured as the change in healthcare costs divided by the change in emergency department transfers/person-month. We assessed joint uncertainty around costs and effects using non-parametric bootstrapping and cost-effectiveness acceptability curves. RESULTS: Point estimates of the incremental cost-effectiveness ratio demonstrated the nurse practitioner-family physician model dominated the internal and combined control groups (i.e. was associated with smaller increases in costs and emergency department transfers/person-month). Compared with the external control, the intervention resulted in a smaller increase in costs and larger increase in emergency department transfers. Using a willingness-to-pay threshold of $1000 CAD/emergency department transfer, the probability the intervention was cost-effective compared with the internal, external and combined control groups was 26%, 21% and 25%. CONCLUSION: Due to uncertainty around the distribution of costs and effects, we were unable to make a definitive conclusion regarding the cost-effectiveness of the nurse practitioner-family physician model; however, these results suggest benefits that could be confirmed in a larger study.

Health technology reassessment of non-drug technologies: current practices.

OBJECTIVES: Obsolescence is a natural phase of the lifecycle of health technologies. Given increasing cost of health expenditures worldwide, health organizations have little choice but to engage in health technology reassessment (HTR); a structured, evidence-based assessment of the medical, social, ethical, and economic effects of a technology, currently used within the healthcare system, to inform optimal use of that technology in comparison to its alternatives. This research was completed to identify and summarize international HTR initiatives for non-drug technologies. METHODS: A systematic review was performed using the terms disinvestment, obsolescence, obsolete technology, ineffective, reassessment, reinvestment, reallocation, program budgeting, and marginal analysis to search PubMED, MEDLINE, EMBASE, and CINAHL until November 2011. Websites of organizations listed as members of INAHTA and HTAi were hand-searched for gray literature. Documents were excluded if they were unavailable in English, if the title/abstract was irrelevant to HTR, and/or if the document made no mention of current practices. All citations were screened in duplicate with disagreements resolved by consensus. RESULTS: Sixty full-text documents were reviewed and forty were included. One model for reassessment was identified; however, it has never been put into practice. Eight countries have some evidence of past or current work related to reassessment; seven have shown evidence of continued work in HTR. There is negligible focus on monitoring and implementation. CONCLUSIONS: HTR is in its infancy. Although health technology reassessments are being conducted, there is no standardized approach. Future work should focus on developing and piloting a comprehensive methodology for completing HTR.

Clinical and Economic Outcomes Associated With Remote Monitoring for Cardiac Implantable Electronic Devices: A Population-Based Analysis.

BACKGROUND: Despite expert recommendations advocating use of remote monitoring (RM) of cardiac implantable electronic devices, implementation in routine clinical practice remains modest due to inconsistent funding policies across health systems and uncertainty regarding the efficacy of RM to reduce adverse cardiovascular outcomes. METHODS: We conducted a population-based cohort study of patients with de novo implantable cardioverter-defibrillators (ICDs) with or without cardiac resynchronization therapy (CRT-D), using administrative health data in Alberta, Canada, from 2010 to 2016. We assessed RM status as a predictor of all-cause mortality and cardiovascular (CV) hospitalization using Cox proportional hazards modelling, and direct health costs by generalized linear models. From this real-world data, we then constructed a decision-analytic Markov model to estimate the projected costs and benefits associated with RM compared with in-clinic visit follow-up alone. RESULTS: Among 2799 ICD and CRT-D patients, 1830 (63.4%) were followed by RM for a mean follow-up of 50.3 months. After adjustment for age, sex, and comorbidities, RM was associated with a lower risk of death (hazard ratio [HR] 0.43, 95% confidence interval [CI] 0.36-0.52; P < 0.001) and CV hospitalization (HR 0.76, 95% CI 0.64-0.91; P = 0.002). In the economic model, cost savings were observed over 5 years with an estimated savings of $12,195 per person (95% CI -$21,818 to -$4,790). The model estimated a cost-savings associated with RM strategy in 99% of simulations. CONCLUSIONS: These population data support more widespread implementation of RM technology to facilitate better patient outcomes and improve health system efficiency.

Long-Term Effects of Tobacco Prices Faced by Adolescents.

Tobacco taxes in Canada varied markedly across time and across regions in the early 1990s. We exploit this variation to estimate the long reach of prices faced in adolescence on smoking behavior roughly a decade later in early to mid-adulthood. Results from a variety of econometric approaches suggest that there is a small but detectable long-run effect of price faced during adolescence. A 10% increase in prices faced during adolescence, holding contemporaneous prices constant, leads to roughly a 1% reduction in adult smoking propensity and intensity. The results are somewhat sensitive to specification and to how price during adolescence is measured.
