Trust in Medical Technology by Patients and Health Care Providers in Obstetric Work Systems

Multiple types of users (i.e. patients and care providers) have experiences with the same technologies in health care environments and may have different processes for developing trust in those technologies. The objective of this study was to assess how patients and care providers make decisions about the trustworthiness of mutually used medical technology in an obstetric work system. Using a grounded theory methodology, we conducted semi-structured interviews with 25 patients who had recently given birth and 12 obstetric health care providers to examine the decision-making process for developing trust in technologies used in an obstetric work system. We expected the two user groups to have similar criteria for developing trust in the technologies, though we found patients and physicians differed in processes for developing trust. Trust in care providers, the technologies' characteristics and how care providers used technology were all related to trust in medical technology for the patient participant group. Trustworthiness of the system and trust in self were related to trust in medical technology for the physician participant group. Our findings show that users with different perspectives of the system have different criteria for developing trust in medical technologies.

Macroegonomics: work system analysis and design

OBJECTIVE

Our goal was to briefly describe how macroergonomics was developed to fill a void in human factors and ergonomics.

BACKGROUND

A study commissioned by the Human Factors Society in 1978 resulted in the formalization of a new subdiscipline of human factors, called organizational design and management, which eventually was coined macroergonomics.

METHOD

Differentiators of macroergonomics are presented along with methods adapted from other domains as well as unique methods.

RESULTS

Based on laboratory and field studies conducted at multiple universities, government facilities, and industries, work system factors can be manipulated in the laboratory and studied in the field successfully. Also, case studies in academia, industry, and government demonstrate 60% to 90% performance impact and positive qualitative changes such as culture change.

CONCLUSION

Macroergonomics offers a perspective as well as methods and tools for more successful human factors and ergonomics design, development, intervention, and implementation.

APPLICATION

Human factors engineers or psychologists and ergonomists can use the perspective of macroergonomics to achieve better results or can expand their involvement of macroergonomics through the use of methods and tools.
