Despite the concern with medical malpractice suits and research about
them, little is known about why some perceived injuries lead to claims
of malpractice while other similar injuries do not. This paper presen
t a conceptualization and hypotheses regarding the determinants of an
injury or perceived injury leading to suit. The conceptualization and
hypotheses are tested using information collected from 113 medical mal
practice plaintiffs' attorneys in three states. A series of proposed c
oncepts prove useful in explaining patient willingness to pursue a sui
t as well as the plaintiff's success and award size. These are concept
s of anger, reluctance to sue, patient and provider worthiness, affini
ty, economic burden and potential for compensation. Specific attribute
s of the injury, the patient, the provider, and the doctor-patient rel
ationship relate to these concepts. Injury and doctor-patient relation
ship attributes prove more important than patient or provider attribut
es. However, the reported impact of the attributes of the patient and
physician on plaintiff success and award is high and suggests that the
impact of ''non-relevant'' variables in the medical malpractice proce
ss. Doctor-patient relationship variables hypothesized to reflect affi
nity are reported to be important in reducing patient willingness to p
ursue a case; and, certain populations, such as minorities, elderly, f
oreign-born, are perceived to have a reluctance to sue. The effect of
specific characteristics of the patient, the doctor, the injury and th
e patient-doctor relationship on patient reaction and on disposition i
s reported, as well as evidence that relates to the validity of the ov
erall conceptualization.
