“…The time trade-off (TTO) valuation technique is a commonly used QoL measurement that is understood by the majority of patients and shows good reproducibility 17. In our study, TTO determined the length of lifetime the respondent would be willing to forego to live in perfect health by asking, ‘Assuming you will only live for 10 years, what is the maximum amount of that time, if any, you would be willing to trade for a return to permanent perfect vision (1.0) during the years that remain?’18…”

ObjectivesTo explore the economic burden, prevalence of catastrophic healthcare expenditure (CHE) and the quality of life (QoL) of Chinese patients with visual impairment (VI) associated with eye diseases.DesignA questionnaire survey from March to May 2016 by structured face-to-face interviews of patients with VI.Participants302 patients who were diagnosed with moderate VI or worse in both eyes (visual acuity <6/18) were included, and 298 patients (98.7%) who completed the survey questionnaires were eligible for the study.Outcome measuresThe economic burden was estimated by calculating participants’ direct costs covered in 2015 and the definition of CHE was out-of-pocket (OOP) costs exceeding 30% of annual household income. QoL was weighed by health utility value using time-trade-off valuation techniques.ResultsAnnual average direct costs per patient caused by VI were US$6988.6±US$10 834.3, and 70.3% were direct medical costs of which only 26.9% were reimbursable by medical insurance. 32.2% of households that suffered from CHE, in particular, were less wealthy patients with VI living in rural areas and without medical insurance. The health utility value was rated at 0.65 on average, and patients with VI aged 51–57, living alone and insured by commercial medical insurance had relatively less QoL.ConclusionOur study explored the economic burden and QoL of VI associated with patients with eye diseases in China, indicating a substantial economic burden and poor QoL. Preferential medical insurance policies should be designed in relation to people with VI to further reduce the health inequalities, avoid CHE and promote QoL.

“…Z is the health utility value; N is the number of years that the respondents are willing to trade for a return to permanent perfect vision. Utility values were anchored on a scale between 0 (the preference for death rather than living in the patient’s current state of health) and 1 (a perception of perfect health) 17…”

“…These scores have been utilized within orthopedics in areas such as adult reconstruction, but as one may imagine, this method would be inappropriate for the pediatric patient. 25 Visual Analog Scale/Feeling Thermometer In young patients for whom the mental exercise of standard gamble and time tradeoff are too abstract, the visual analog scale/feeling thermometer is utilized. 24,[26][27][28][29] This involves providing a description of a given health state in plain language, and asking subjects to numerically rank their preference for each state from a scale of 0 to 100 (i.e., the feeling thermometer), with 100 being perfect health and 0 being equivalent to the worst health imaginable.…”

Healthcare expenditures in the United States continue to rise without corresponding improvements in outcomes. Because of this, there is increasing pressure on physicians to consider the economic impacts of their medical decisions. Unfortunately, physicians in general are unfamiliar with interpreting and performing various health economic analyses. A basic understanding of health economics may help physicians understand and participate in key policy discussions which may shape the future of medicine and surgery. In the field of pediatric orthopaedics specifically, the literature involving health economic evaluation is sparse. This may be due to a combination of unfamiliarity with the topic and also difficulties with applying economic evaluation methods to the pediatric population. However, many interventions in this field are low cost with many potential benefits that accrue over a child’s long lifespan. Economic evaluation can help objectively quantify the impact of these interventions, as well as bolster responsible medical decision-making. To that end, the purpose of the current review is to introduce the pediatric orthopaedic community to commonly utilized healthcare economic tools including cost-benefit analysis, cost-effectiveness analysis, and cost-utility analysis with a focus on several key concepts including value, quality, time, cost, and discounting. To help illustrate these concepts, health economic literature relevant to pediatric orthopaedics is discussed. Finally, we highlight limitations inherent to health economic evaluations in general and those applicable to pediatric orthopaedics specifically. This discussion may help lay the groundwork for future studies and for further involvement in policy-making.
