Increasingly questions are being raised about the ability of many curr
ent health reforms to address the challenges that are facing health sy
stems. We investigate this situation by exploring the role of professi
onalism in the delivery of health services. In contrast to the dominan
t approach of considering professionalism as a social phenomenon, prof
essionalism is considered as primarily a task-related phenomenon. The
characteristics of the task are identified as being high levels of unc
ertainty and complexity. These characteristics are shown to lead natur
ally to the key social features that typify professionalism. Hence, th
e close link between professionalism and the nature of the task is arg
ued. However, health reforms threaten professionalism. They have been
based on considerable dissatisfaction with the performance of professi
onals as well as the emergence of a number of new challenges. In addit
ion, the reforms have been developed without significant consideration
of the central role that professionalism has played, and reformers ha
ve adopted a simplified view of the task. Thus, the centrality of prof
essionalism has intrinsically been downgraded. However, this simplific
ation can be shown to be inconsistent with the realities and complexit
ies of health service provision, and thus the downgrading of professio
nalism is unwarranted. This inconsistency generates many of the confli
cts and contradictions being reported. The future of health service re
form depends on an effective understanding of the nature of the task,
recognition of the central role of professionalism and the development
of professional and organisational structures that support each other
