Research suggests that physicians will engage in more vigilant problem-solving under conditions of resource constraints than under conditions of resource slack. Increased vigilance related to physicians' clinical strategies enhances care by disposing physicians toward more optimal care choices. The authors examine whether pressures for clinical resource constraints encourage increased and sustained vigilance in problem-solving among cardiologists treating acute myocardial infarction.
The physician problem-solving process is reconstructed from the medical records of all eligible cases of acute myocardial infarction treated by the physician sample set over a 6-year period. The sample period encompasses phases of both resource slack and resource constraints. The Herfindahl index is used to measure the relative amount of vigilant problem-solving activity exhibited in each of five major tactical areas of the physician care strategies in each year of the study.
The results support the hypothesis that resource constraints initially promote a shift to increased vigilance in physician problem-solving. Only one of the five major tactical areas, however, is characterized by sustained vigilance over time. The other areas are, instead, associated with a substantial reduction in vigilant activity after the initial peak period.
The results suggest that resource constraints do set the stage for improved clinical decision-making. Sustained vigilance, however, appears to apply only to those portions of the care strategy for which the physician can draw a clear link between optimizing clinical activity and reducing resource consumption. For those portions of the care strategy for which the physician cannot establish a clear link, ongoing pressures to conserve resources results in reduced vigilance and a potential reduction in quality of clinical decision-making.
研究表明,与资源充裕的情况相比,医生在资源受限的情况下会更积极地解决问题。与医生临床策略相关的更高警觉性通过促使医生做出更优的治疗选择来提高医疗质量。作者探讨了临床资源受限的压力是否会促使治疗急性心肌梗死的心脏病专家在解决问题时提高并持续保持警觉性。
从医生样本集在6年期间治疗的所有符合条件的急性心肌梗死病例的医疗记录中重建医生解决问题的过程。样本期涵盖了资源充裕和资源受限两个阶段。赫芬达尔指数用于衡量研究每年中医生治疗策略的五个主要战术领域中每个领域所表现出的积极解决问题活动的相对量。
结果支持这样的假设,即资源受限最初会促使医生在解决问题时提高警觉性。然而,五个主要战术领域中只有一个随着时间的推移表现出持续的警觉性。其他领域则相反,在初始高峰期过后积极活动大幅减少。
结果表明资源受限确实为改善临床决策奠定了基础。然而,持续的警觉性似乎仅适用于医生能够在优化临床活动与减少资源消耗之间建立明确联系的治疗策略部分。对于医生无法建立明确联系的治疗策略部分,持续的资源节约压力会导致警觉性降低以及临床决策质量可能下降。
