Increasingly, nurses use the philosophy of hermeneutics, especially Heideggerian and Gadamerian hermeneutics, to inform interpretive research. However, application of the work of these philosophers to interpretive nursing research has proved problematic as it fails to recognise, or act upon, obligations inherent in their work. Through a review of hermeneutically informed nursing research, methodological implications regarding the use of hermeneutic philosophy are examined in relation to: (i) the need to address forestructures and pre-understandings; (ii) checking interpretations with research participants; (iii) seeking (...) objectivity, consensus and accuracy in textual interpretation; (iv) evaluating interpretations; and (v) gaining entry into the hermeneutic circle. This review suggests that despite obligations inherent in Heideggerian and Gadamerian hermeneutic philosophy, nurses fail to actualise these obligations in their research. In following Heidegger, nurses need to make the scientific theme secure by working out their forestructures in terms of the phenomenon under investigation. Those following Gadamer need to accept that interpretation seeks to manifest textual meanings rather than individual ones. And, whether following Heidegger or Gadamer, the way to make manifest textual meanings is to engage with the text within the hermeneutic circle by continuing to address forestructures and pre-understandings and by considering their influences upon the research.
