Long‐term Effects of Managed Care

Abstract

Managed care (MC) plans have been introduced to curb the ever increasing health care costs. Many previous studies on effectiveness lacked a long-term perspective; hence, the sustainability of (possible) savings remains unclear. Moreover, because of their incentives, MC plans are susceptible to under-provision of care. Most of these possibly negative effects can only be observed in the long-term. This paper analyzes the long-term effects of MC plans on cost savings, mortality, and the use of service, using administrative data from a large Swiss health insurer. The identification is based on a propensity-score matching approach, where individuals who enter an MC plan are compared over 10 years to individuals who remain in a standard fee-for-service plan. Cost savings are substantial and sustainable, and the mortality rate is lower in MC plans. Cost savings are driven by fewer consultations and fewer days in hospital care, although the probability of visiting a provider at least once per year is similar or even higher for persons in MC plans.

Rents for Pills: Financial Incentives and Physician Behavior

“…Cost savings and lower utilization of managed care patients have been repeatedly documented in the literature (e.g. Kauer, 2017;Gaynor et al, 2004;Cutler et al, 2000). While part of the lower costs can be explained by patient selection, these studies highlight the relevance of incentives and provider selection.…”

Evaluation of the Effect of a Multifunctional Telemedicine Device on Health Care Use and Costs: A Nonrandomized Pragmatic Trial

“…4 Gatekeeping is thus intended to prevent unnecessary specialist and inpatient services use and reduce costs. 5,6 Such effects have already been demonstrated in a variety of studies [7][8][9] , with savings also achieved in the more recent telemedicine call center models. 10 In the case of the medical call centers, a medical professional in a call center acts as a gatekeeper who carries out the initial assessment and then decides on referral to the next level of care.…”

Policies for Switzerland’s ageing society

“…Managed care insurance plans, which restrict patients' choice of service provider, expanded from 7% of the market in 2000 to 64% in 2017. This system has already reduced overuse of health care and generated substantial cost savings (Kauer, 2016). A risk equalisation mechanism transfers money between insurance companies to adjust for selection effects but it does not take into account many risk factors (OECD, 2015b).…”
