4. Discussion and implications
Our review of HIT publications highlights several key findings about this specialty within the IS academic field: i) HIT research is increasing in scale and scope across top journals in the IS discipline; ii) the topical focus of HIT research, although weighted toward organizational and inter-organizational studies of administrative and clinical systems, is diversifying to new phenomena developing in health care and technology; iii) the majority of HIT publications in leading IS journals articulate contributions to knowledge in terms of IS theory based on empirical research at the intersection of IS and health care concerns; and, iv) a growing number of publications suggests IS researchers are more explicitly addressing specific health industry priorities and information challenges through their research published in IS journal outlets. During the review study period (2004–2017), a substantial volume of HIT research has addressed how individual stakeholder organizations apply HIT to solve internal problems and improve processes and outcomes through HIT adoption and use. In the future, we suggest the frontier of practical questions and research opportunities will emerge at the intersection of HIT between the field's diverse stakeholder groups and through field-level (versus organizational-level) transformation. Drawing on our observations of health sector trends as scholars experienced in this specialty and through this literature review process, we now highlight areas for future HIT research that we believe could usefully inform IS theory and health care system practice.
