Thinking outside the black box: the importance of context in understanding the impact of a preoperative education nursing intervention among Chinese cardiac patients.

Abstract

OBJECTIVE: In a randomized controlled trial of a preoperative education intervention conducted for Chinese cardiac patients, we observed a greater effect on symptoms of anxiety and depression than that reported with regard to similar interventions in western care settings. The objective of this qualitative study was to help explain the findings of the trial by exploring Chinese patients' experience of seeking and receiving information before cardiac surgery. METHODS: Semi-structured interviews were conducted with a purposive sample of 20 trial participants before discharge (ten from the preoperative education group; ten from the usual care control group). Data were analyzed using a thematic analysis approach. RESULTS: A total of five themes were generated: the role of reputation and hierarchy; gaining strength from knowledge; information as a low priority; being kept in the dark; and learning through peer support. CONCLUSION: In health care systems where service users are given relatively little information, interventions designed to inform patients about their treatment are likely to have a much greater impact on their psychological health. PRACTICE IMPLICATIONS: Providers of services for patients undergoing cardiac surgery in China should be encouraged to incorporate information giving into routine practice, tailored according to individual need.
