Simple interventions resolve the problem of missed lab appointments. It is essential that patients complete ordered laboratory studies. This maintains clinical quality and, potentially, keeps patients safe from harm. In our academic family medicine practice, baseline data demonstrated patients completed 94.7% of labs as ordered (26850/28348 patients per year) while 1498 (5.3%) did not. Our baseline patient reminder process, a mail or portal based generic letter, resulted in only 449 (30%) of patients ultimately completing them (1049 [70%] did not). Our baseline system was 96.3 % reliable. This process did not allow for provider review or input, and was not personalized for patients. We designed a quality improvement project involving three PDSA (Plan, Do, Study, and Act) cycles of about two months each. Desk staff created weekly reports of unresolved lab orders. A message in the electronic medical record (EMR) solicited provider input. Providers could elect to cancel studies (if already completed, reordered, or no longer clinically indicated) or have the patient receive a personalized reminder, including provider name and associated diagnoses. This reminder was sent by patient portal secure messaging (if an account existed) or with a mailed letter. These interventions resulted in 98.8 % process reliability. The frequency of unresolved lab orders decreased from 70% at baseline to 25%. In the second PDSA cycle, we contacted patients by the portal only if there was evidence of an active account. Otherwise, they were contacted by telephone. Patients without a portal account continued to receive a letter by mail. These modified processes resulted in an overall reliability rate of 99.2%. The frequency of unresolved lab orders decreased to 17%. A final PDSA cycle utilized only telephone contact with patients with unresolved lab orders. Schedulers offered patients a choice of appointment dates if they spoke personally. Otherwise, they were left messages with a future lab appointment date two weeks later.Overall process reliability now increased to 100%. The frequency of unresolved lab orders decreased to 0%. Our interventions resulted in increased system reliability.Provider input was not perceived as burdensome. Desk staff work effort was not increased.Telephone patient contact resulted in more frequent lab order completion than other methods.
