Aim: To uncover the characteristics of nurses' information practice in municipal health care and to address how, when and why various pieces of information are produced, shared and managed. Background: Nursing documentation in the electronic patient record has repeatedly been found unsatisfactory. Little is known about how the information practice of nurses in municipal health care actually is borne out. In order to understand why nursing documentation continues to fail at living up to the expected requirements, a better understanding of nurses' information practice is needed. Design: A qualitative observational field study. The study complied with the Consolidated Criteria for Reporting Qualitative Research. Methods: Empirical data were collected in three Norwegian municipalities through participant observations and individual interviews with 17 registered nurses on regular day shifts. The data were analysed through thematic content analysis. Results: Nurses' information practice in municipal health care can be described as complex. The complexity is reflected in four themes that emerged from the data: (1) web of information sources, (2) knowing the patient and information redundancy, (3) asynchronous information practice and (4) compensatory workarounds. Conclusions: The complex and asynchronous nature of nurses' information practice affected both how and when information was produced, recorded and shared. When available systems lacked functions the nurses wanted, they created compensatory workarounds. Although electronic patient record was an important part of their information practice, nurses in long-term care often knew their patients well, which meant that a lot of information about the patients was in their heads, and that searching for information in the electronic patient record sometimes seemed redundant. Relevance to clinical practice: This study provides contextual knowledge that might be valuable (a) in the further development of information systems tailored to meet nurses' information needs and (b) when studying patient safety in relation to nurses' information practice.
