Developing health service systems in order to improve the health and q
uality of the lives of patients may benefit from evaluation studies co
mbining a quantitative survey methodology with qualitative interviews
and observations, Studies using a combination of these methods may pro
mote and advance system changes, Quantitative methods provide necessar
y documentation of the needs and effects of system changes, They may t
herefore motivate decision makers to initiate changing processes, Qual
itative methodology is suited for uncovering social conflicts and prob
lems that projects attempting to change health systems often meet, The
y provide data which may be valuable in the motivation and education o
f the professions involved in the health service systems, This paper r
eports on some of the underlying social conflicts which were uncovered
by a study evaluating the impact of the introduction of a new food sy
stem in a hospital ward for children with cancer, Qualitative intervie
ws and observations revealed severe status differences between patient
s and staff, For the patients and their families the food was a centra
l part of their quality of life while staying in the hospital, For the
staff the patients' food was a neglected area with low status, This w
as changed by the new food system which was organized with considerati
on of the social structures of hospitals and other total institutions,
This paper argues that projects aiming al: improving the quality of l
ife of patients through system changes must address the social conflic
ts and the status system embedded in the organization of the service t
o be changed.
