A regional healthcare network analyzed performance data from its twenty member hospitals over a two-year period. The network found that the five hospitals that voluntarily installed automated self-service check-in kiosks experienced a 20 percent decrease in average emergency room wait times. Based on this observation, the executive board concluded that installing these kiosks across the remaining fifteen hospitals will lead to a comparable decrease in patient wait times across the entire network.
The executive board's reasoning is most vulnerable to criticism on the grounds that it
- fails to account for the possibility that the hospitals that voluntarily installed the kiosks possessed other structural or administrative advantages that contributed to the shorter wait times.Cevap
- Bconfuses a condition that is necessary for decreasing patient wait times with one that is sufficient to achieve that decrease.
- Cmistakenly presumes that shorter patient wait times caused hospital administrators to install automated check-in kiosks.
- Dassumes without justification that overall patient medical outcomes will improve as a direct result of installing check-in kiosks.
- Ecompares hospitals based on check-in technology while ignoring unrelated operational metrics such as surgical success rates.
Cevap
The argument is vulnerable because it fails to consider that hospitals voluntarily adopting self-service kiosks may have had other preexisting operational efficiencies that led to reduced wait times.
The correct answer identifies a classic self-selection flaw. Because the five hospitals voluntarily chose to install the kiosks, they may differ systematically from the remaining fifteen hospitals—for example, possessing better administrative workflow, updated triage software, or more flexible staffing. Thus, the observed reduction in wait times cannot be definitively attributed solely to the kiosks, nor can one guarantee identical results when mandating kiosks across non-adopting facilities.
