A stage-dependent model of resource utilization,strategic flexibility,and implications for performance over time: Empirical evidence from a transitional environment

It has long been recognized that there is a tradeoff between exploration and exploitation. How organizations utilize resources across time and space will affect firm survival and growth. In this paper, we examine resource utilization and performance implications over time in an environment undergoing fundamental institutional transformation. Based on a large archive of Chinese government data from 1988, 1992, and 1996, the study finds that (1) the impact of resource utilization is contingent on the degree to which different resources are committed to factors of production, (2) the impact is curvilinear and only valid within an “optimal” range, and (3) the performance implications change over time. As firms enter later stages of the transitional process, efficiency becomes less important as they shift their strategic focus from exploitation to exploration, which requires more flexibility. These findings have significant bearing on the issue of upgrading technological competitiveness in China as the country becomes increasingly integrated in the global economy. Such insights may also have implications for other emerging economies in Asia.

Guidelines-based treatment associated with improved economic outcomes in nontuberculous mycobacterial lung disease

Abstract

Background: The prevalence of nontuberculous mycobacterial lung disease (NTMLD) in the US has increased; however, data characterizing the associated healthcare utilization and expenditure at the national level are limited.

Objective: To examine associations between economic outcomes and the use of anti-Mycobacterium avium complex (MAC) guidelines-based treatment (GBT) for newly-diagnosed NTMLD in a US national managed care claims database (Optum^® Clinformatics^® Data Mart).

Methods: NTMLD was defined as having ≥2 claims for NTMLD (ICD-9 031.0; ICD-10 A31.0) on separate occasions ≥30?days apart (between 2007 and 2016). The cohort included patients insured continuously over a period of at least 36?months (12?months before initial NTMLD diagnostic claim and for the subsequent 24?months). Treatment was classified as GBT (consistent with American Thoracic Society/Infectious Diseases Society of America guidelines), non-GBT, or untreated. All-cause hospitalization rates and total healthcare expenditures at Year 2 were assessed as outcomes of the treatment prescribed in Year 1 after NTMLD diagnosis.

Results: A total of 1,039 patients met study criteria for NTMLD (GBT, n?=?294; non-GBT, n?=?298; untreated, n?=?447). After adjustment for baseline characteristics, GBT was associated with a significantly lower all-cause hospitalization risk vs non-GBT (odds ratio [OR]?=?0.53; 95% CI = 0.33–0.85, p?=?0.008), and vs being untreated (OR = 0.57; 95% CI = 0.35–0.91, p?=?0.020). Adjusted total healthcare expenditure in Year 2 with GBT ($69,691) was lower than that with non-GBT ($77,624) with a difference of ?$7,933 (95% CI = ?$14,968 to ?$899; p?=?0.03).

Conclusions: Patients with NTMLD in a US managed care claims database who were prescribed GBT had lower hospitalization risk than those who were prescribed non-GBT or were untreated. GBT was associated with lower total healthcare expenditure compared with non-GBT.     

Observational evaluation of outcomes and resource utilization from hemostatic matrices in spine surgery

Abstract

Objective:

Studies have indicated that outcomes may differ by choice of flowable hemostat, but there is limited evidence in spine surgery. The objective of this study was to conduct a comparison of outcomes following use of advanced flowable hemostatic matrices in a large spine surgery population.
