Factors associated with undertriage and overtriage in telephone triage in Danish out-of-hours primary care: a natural quasi-experimental cross-sectional study of randomly selected and high-risk calls.

OBJECTIVES: We aim to explore undertriage and overtriage in a high-risk patient population and explore patient characteristics and call characteristics associated with undertriage and overtriage in both randomly selected and in high-risk telephone calls to out-of-hours primary care (OOH-PC). DESIGN: Natural quasi-experimental cross-sectional study. SETTING: Two Danish OOH-PC services using different telephone triage models: a general practitioner cooperative with GP-led triage and the medical helpline 1813 with computerised decision support system-guided nurse-led triage. PARTICIPANTS: We included audio-recorded telephone triage calls from 2016: 806 random calls and 405 high-risk calls (defined as patients ≥30 years calling with abdominal pain). MAIN OUTCOME MEASURES: Twenty-four experienced physicians used a validated assessment tool to assess the accuracy of triage. We calculated the relative risk (RR) for clinically relevant undertriage and overtriage for a range of patient characteristics and call characteristics. RESULTS: We included 806 randomly selected calls (44 clinically relevant undertriaged and 54 clinically relevant overtriaged) and 405 high-risk calls (32 undertriaged and 24 overtriaged). In high-risk calls, nurse-led triage was associated with significantly less undertriage (RR: 0.47, 95% CI 0.23 to 0.97) and more overtriage (RR: 3.93, 95% CI 1.50 to 10.33) compared with GP-led triage. In high-risk calls, the risk of undertriage was significantly higher for calls during nighttime (RR: 2.1, 95% CI 1.05 to 4.07). Undertriage tended to be more likely for calls concerning patients ≥60 years compared with 30-59 years (11.3% vs 6.3%) in high-risk calls. However, this result was not significant. CONCLUSION: Nurse-led triage was associated with less undertriage and more overtriage compared with GP-led triage in high-risk calls. This study may suggest that to minimise undertriage, the triage professionals should pay extra attention when a call occurs during nighttime or concerns elderly. However, this needs confirmation in future studies.

Communication quality in telephone triage conducted by general practitioners, nurses or physicians: a quasi-experimental study using the AQTT to assess audio-recorded telephone calls to out-of-hours primary care in Denmark.

OBJECTIVES: To compare the quality of communication in out-of-hours (OOH) telephone triage conducted by general practitioners (GPs), nurses using a computerised decision support system and physicians with different medical specialities, and to explore the association between communication quality and efficiency, length of call and the accuracy of telephone triage. DESIGN: Natural quasi-experimental cross-sectional study. SETTING: Two Danish OOH services using different telephone triage models: a GP cooperative and the medical helpline 1813. PARTICIPANTS: 1294 audio-recorded randomly selected OOH telephone triage calls from 2016 conducted by GPs (n=423), nurses using CDSS (n=430) and physicians with different medical specialities (n=441). MAIN OUTCOME MEASURES: Twenty-four physicians assessed the calls. The panel used a validated assessment tool (Assessment of Quality in Telephone Triage, AQTT) to measure nine aspects of communication, overall perceived communication quality, efficiency and length of call. RESULTS: The risk of poor quality was significantly higher in calls triaged by GPs compared with calls triaged by nurses regarding 'allowing the caller to describe the situation' (GP: 13.5% nurse: 9.8%), 'mastering questioning techniques' (GP: 27.4% nurse: 21.1%), 'summarising' (GP: 33.0% nurse: 21.0%) and 'paying attention to caller's experience' (GP: 25.7% nurse: 17.0%). The risk of poor quality was significantly higher in calls triaged by physicians compared with calls triaged by GPs in five out of nine items. GP calls were significantly shorter (2 min 57 s) than nurse calls (4 min 44 s) and physician calls (4 min 1 s). Undertriaged calls were rated lower than optimally triaged calls for overall quality of communication (p<0.001) and all specific items. CONCLUSIONS: Compared with telephone triage by GPs, the communication quality was higher in calls triaged by nurses and lower in calls triaged by physicians with different medical specialities. However, calls triaged by nurses and physicians were longer and perceived less efficient. Quality of communication was associated with accurate triage.

Communicative characteristics of general practitioner-led and nurse-led telephone triage at two Danish out-of-hours services: an observational study of 200 recorded calls.

OBJECTIVES: Out-of-hours (OOH) telephone triage is used to manage patient flow, but knowledge of the communicative skills of telephone triagists is limited. The aims of this study were to compare communicative parameters in general practitioner (GP)-led and nurse-led OOH telephone triage and to discuss differences in relation to patient-centred communication and safety issues. DESIGN: Observational study. SETTING: Two Danish OOH settings: a large-scale general practitioner cooperative in the Central Denmark Region (n=100 GP-led triage conversations) and Medical Helpline 1813 in the Capital Region of Denmark (n=100 nurse-led triage conversations with use of a clinical decision support system). PARTICIPANTS: 200 audio-recorded telephone triage conversations randomly selected. PRIMARY AND SECONDARY OUTCOME MEASURES: Conversations were compared with regard to length of call, distribution of speaking time, question types, callers' expression of negative affect, and nurses' and GPs' responses to callers' negative affectivity using the Mann-Whitney U test and the Student's t-test. RESULTS: Compared with GPs, nurses had longer telephone contacts (137s vs 264 s, p=0.001) and asked significantly more questions (5 vs 9 questions, p=0.001). In 36% of nurse-led triage conversations, triage nurses either transferred the call to a physician or had to confer the call with a physician. Nurses gave the callers significantly more spontaneous talking time than GPs (23.4s vs 17.9 s, p=0.01). Compared with nurses, GPs seemed more likely to give an emphatic response when a caller spontaneously expressed concern; however, this difference was not statistically significant (36% vs 29%, p=0.6). CONCLUSIONS: When comparing communicative parameters in GP-led and nurse-led triage, several differences were observed. However, the impact of these differences in the perspective of patient-centred communication and safety needs further research. More knowledge is needed to determine what characterises good quality in telephone triage communication.
