10.4 DIAGNOSES WITH INVESTIGATIONS ORDERED
Table 10.4.1 reports the most common diagnoses for which investigations were ordered in primary care in 2014.
• The top 10 diagnoses for which investigations were most frequently ordered accounted for 73.2 of all diagnoses accompanied by tests.
• Diabetes accounted for a quarter 24.3 of the diagnoses with at least one investigation ordered. This corresponds with another finding in NMCS 2014 that glucose andor glucose tolerance test
was the most frequently ordered investigation in primary care see Section 10.2. • The second most common diagnosis for which investigations were ordered was hypertension, which
amounted to 16.0 of all diagnoses accompanied by tests, followed by lipid disorder at 9.6. • Together, the three aforementioned chronic diseases represented half 49.9 of all diagnoses for
which investigations were ordered, a finding which could be attributed to the high burden of the three metabolic syndrome-related conditions in primary care see Chapter 8.
