Background: Belgium has a problem with inappropriate use of emergency services. The government installed the number 1733 for out-of-hours care. Through a dry run test, we learned that 30% of all calls were allocated to the protocol ‘unclear problem’. In only 11.9% of all cases, there was an unclear problem. Methods: The study aimed to determine whether the adjusted protocol ‘unwell for no clear reason’ led to a safer and more efficient referral and to evaluate the efficiency and safety of the primary care protocols (PCPs). The study ran in cross-sectional design involving patients, General Practitioner Cooperatives and telephone operators. A random sample of calls to 1733 and patient referrals were assessed on efficiency and safety. Results: During 6 months in 2018, 11 622 calls to 1733 were registered. Seven hundred fifty-six of them were allocated to ‘unwell for no clear reason’, and a random sample of 180 calls was audited. To evaluate the PCPs, 202 calls were audited. The efficiency and safety of the protocol ‘unwell for no clear reason’ improved, and safety levels for under- and over-triage were not exceeded. The GP’s judged that 9/10 of all patient encounters were correctly referred. Conclusion: This study demonstrated that the 1733-telephone triage system for out-of-hours care is successful if protocols, flow charts and emergency levels are well defined, monitored and operators are trained.

Background In Belgium there is a problem with improper use of emergency services. The government installed an emergency number 1733 for out of hours care. Through a dry run test we learned that 10% of all calls were allocated to the protocol ‘unclear problem’. In only 10% of all cases, there was indeed an unclear problem.Methods This study aimed to determine whether the adjusted protocol ‘unwell for no clear reason’ led to a safer and more efficient referral and to evaluate the efficiency and safety of the specific primary care protocols. The study was performed in a retrospective and prospective design and involved the community, patients, General Practitioner Cooperatives, emergency departments and telephone operators.Results During 6 months in 2018, 11622 calls to 1733 were registered. 756 of these calls were allocated to ‘unwell for no clear reason’. A random sample of 180 calls was re-listened. The efficiency and safety of the protocol ‘unwell for no clear reason’ improved. The safety levels for under- and over-triage were not exceeded. The GP’s on duty judged that 9/10 of all patient encounters were correctly allocated. In less than 1% of all referrals, there was an under-triage.Conclusion This study demonstrated that the implementation of a 1733-operating system to triage patients to an adequate care level is successful if protocols, flow charts and care levels are well defined and operators well trained.
