Investigating the effectiveness of virtual treatment via telephone triage in a New Zealand general practice

IntroductionTelemedicine, including telephone triage, is increasingly being used in New Zealand general practices. Telephone triage involves diverting requests for same-day healthcare to a phone system where presenting complaints are explored only sufficiently to identify the most appropriate management pathway. AimTo assess the rates of repeat triage among general practice patients treated virtually via phone and compare these with outcomes for patients who were dealt with in person. Method6 weeks of clinical telephone triage data were collected for Gore Medical Centre. Comparisons were made for patients treated virtually or in person, for whether complaints were a respiratory issue or not, and for whether their triage represented incomplete resolution of a previously triaged health complaint. To do this, patient notes for the 7 days prior to the phone triage were reviewed for medical consultations related to the same condition. ResultsOver 6 weeks, 455 telephone triages took place at the Gore Medical Centre: 133 triage phone calls resulted in 132 (29%) patients being treated virtually. Over the 6 study weeks, 19 virtually treated triage patients phoned again for further care of the same problem within 7 days (14%) while 23 patients (7%) who had been triaged to in person assessment also sought further care within 7 days. This difference was statistically significant (P < 0.05). There was no statistical difference in re-triage rates between Māori and non-Māori. Young age was a significant predictor for likelihood of re-triage. DiscussionVirtual treatment via telephone triage at Gore Medical Centre resulted in a statistically increased likelihood of re-triage within 7 days compared with in person treatment. This raises questions about the efficacy of virtual treatment via telemedicine compared with in person treatment after triage.
