12.4.3 The side effects of nonsteroidal antiinflammatory drugs (NSAIDs) include problems involving peptic ulceration, renal function, and liver disease. In 1996, the American College of Rheumatology issued and disseminated guidelines recommending baseline tests (CBC, hepatic panel, and renal tests) when prescribing NSAIDs. A study was conducted by Rothenberg and Holcomb (A-6) to determine if physicians taking part in a national database of computerized medical records performed the recommended baseline tests when prescribing NSAIDs. The researchers classified physicians in the study into four categories-those practicing in internal medicine, family practice, academic family practice, and multispeciality groups. The data appear in the following table. Practice Type Internal medicine Performed Baseline Tests Yes 294 98 50 203 No 921 2862 3064 2652 Family practice Academic family practice Multispecialty groups Source: Ralph Tothenberg and John P. Holcomb, "Guidelines for Monitoring of NSAIDs: Who Listened?" Journal of Clinical Rheumatology, 6 (2000), 258-265. Do the data above provide sufficient evidence for us to conclude that type of practice and performance of baseline tests are related? Use a = .01.
