Cases with psychiatric indications are classified in the "Protocol 25" and receive an A-, B-, C-, D-, or O-coding according to their urgency with different subdivisions and characteristics [e.g. 25D03V]. Acute cases (e.g. suicidality) with a high priority can thus be distinguished from less acute cases (e.g. anxiety states, psychic exceptional states). No diagnoses are made and no ICD codes are assigned.
Conditions
Interventions
Group 1: Intervention group: Callers to the 112 number who have been assigned the code for low acute psychosocial needs (protocol 25A01-03/25O01-02) by the dispatching center receive PSAPL counseling.

Inclusion criteria
Inclusion criteria: All help-seekers who call or have called the Berlin Fire Department's dispatch center in the calendar year 2023-2025. Routine data analysis will be performed on these data to better characterize the callers and the circumstances of the calls in relation to the codes considered (25A01 / 25O01). In October 2024, the Berlin Fire Brigade changed their procedure and expanded their intervention-relevant inclusion codes to 25A01-03 / 25O01-02, which will be considered separately from the primary intervention codes (25A01 / 25O01) in the evaluation study.
Exclusion criteria
Exclusion criteria: All 112 emergency calls received by the Berlin Fire Department dispatch center outside of the 2023 to 2025 time period, as well as calls during the period under review from the police and specialist mental health services (Social Psychiatric Service [SpDi], Berlin Crisis Service).
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary quantitative endpoint is the proportion of ambulance dispositions for individuals with low acute psychosocial needs (protocol 25A01/25O01) between the intervention and control group. This will also be examined in relation to a reference period (calendar year 2023). It is assumed that there will be a reduction in the number of ambulance dispositions and thus in hospital transfers. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary quantitative endpoints: Proportion of ambulance dispositions for persons with low acute psychosocial needs (Protocol 25A01-03/25O01-02) between intervention and control group. Proportion of transports to the emergency department for persons with protocol 25A01-03/25O01-02 among all cases with dispatch of an ambulance between the intervention and control group. Absolute number and percentage of all cases with dispatch codes 25A01-03 and 25O01-02 that occur during PSAPL staffing times as a percentage of all cases with dispatch codes 25A01-03 and 25O01-02 and all calls with dispatch codes. (Efficiency of implementation) Percentage of cases that can be forwarded to the PSAPL during staffing hours, out of all cases with codes 25A01-03 and 25O01-02. Analysis of the Berlin Fire Brigade's routine data over the period 2023-2025 for the frequency of cases with 25A01-03 and 25O01-02 and comparison with other cases. Calling person (person himself/herself, other persons, spatial proximity to person) Proportion of all cases with codes 25A01-03 and 25O01-02 between the intervention and control group. This will also be examined in relation to a reference period (calendar year 2023). The establishment of a PSAPL and the service associated with it could lead to more calls with this code. All secondary endpoints are calculated primarily using codes 25A01 and 25O01, with supplementary calculations using codes 25A02-03 and 25O02. Quantitative Endpoints from PSAPL routine data of the Berlin Fire Department Absolute and relative frequencies - Red flags that lead to the dispatch of an ambulance - Person who receives counseling (caller, other person) - Social and spatial environment - Reasons for consultation - Performed interventions - Transfer back to the dispatch center - Initiation of a response vehicle - Abandoned call - Recurring calls - Duration of calls (min) in total and for different consultation reasons - Satisfaction with PSAPL advice, | — |
