<title>Background:</title>
<p>Cardiopulmonary resuscitation (CPR) education in schools is a proven strategy to increase layperson intervention rates and improve survival outcomes in out-of-hospital cardiac arrest (OHCA). In Germany, only 51% of OHCA patients receive layperson CPR, compared to 85% in Norway, contributing to a lower 30-day survival rate (10.4% vs. 14%). Despite a 2014 recommendation for school-based CPR training, nationwide implementation remains inadequate.</p>
</sec>
<sec>
<title>Methods:</title>
<p>This study utilized a descriptive survey to investigate barriers to CPR education implementation in German schools and federal states. Teachers from schools that previously withdrew from a Brandenburg pilot project were interviewed, and education ministries across all 16 federal states were consulted. Data analysis included qualitative and quantitative methods to identify key challenges and potential solutions.</p>
</sec>
<sec>
<title>Results:</title>
<p>Amongst the 33 schools initially enrolled in the pilot project, only five completed it, with 28 withdrawing. Teachers from schools that withdrew cited time constraints (66.7%), lack of teaching materials (58.3%), and insufficient training opportunities (75%) as major barriers. The survey of education ministries revealed that only two federal states had comprehensively implemented CPR education, while six had integrated it into their curricula.</p>
</sec>
<sec>
<title>Conclusion:</title>
<p>Despite strong support from educators, structural deficits, insufficient funding, and organizational shortcomings hinder sustainable CPR training in German schools. Financial investment, standardized teaching materials, and nationwide coordination are essential to overcoming these barriers. Without concrete political and financial commitments, Germany risks continued stagnation in CPR education, limiting potential improvements in OHCA survival rates.</p>

<title>Hintergrund:</title>
<p>Die Schulung in Wiederbelebungsma&#223;nahmen (CPR) in Schulen ist eine bew&#228;hrte Strategie, um die Laienreanimationsrate zu erh&#246;hen und die &#220;berlebenschancen bei einem au&#223;erklinischen Herz-Kreislauf-Stillstand (OHCA) zu verbessern. In Deutschland erhalten lediglich 51 % der OHCA-Patienten eine Laienreanimation, im Vergleich zu 85 % in Norwegen, was zu einer geringeren 30-Tage-&#220;berlebensrate f&#252;hrt (10,4 % vs. 14 %). Trotz einer Empfehlung aus dem Jahr 2014 zur Einf&#252;hrung von CPR-Schulungen in Schulen ist eine fl&#228;chendeckende Umsetzung bislang unzureichend.</p>
</sec>
<sec>
<title>Methoden:</title>
<p>Diese Studie verwendete eine deskriptive Umfrage, um Hindernisse bei der Umsetzung von CPR-Schulungen in deutschen Schulen und Bundesl&#228;ndern zu untersuchen. Lehrkr&#228;fte von Schulen, die sich aus einem Brandenburger Pilotprojekt zur&#252;ckgezogen hatten, wurden befragt, ebenso wie Bildungsministerien aller 16 Bundesl&#228;nder. Die Datenauswertung erfolgte mittels qualitativer und quantitativer Methoden, um zentrale Herausforderungen und m&#246;gliche L&#246;sungsans&#228;tze zu identifizieren.</p>
</sec>
<sec>
<title>Ergebnisse:</title>
<p>Von den 33 urspr&#252;nglich am Pilotprojekt teilnehmenden Schulen f&#252;hrten nur f&#252;nf das Projekt vollst&#228;ndig durch, w&#228;hrend 28 sich zur&#252;ckzogen. Lehrkr&#228;fte der aus dem Projekt ausgetretenen Schulen nannten Zeitmangel (66,7 %), fehlende Unterrichtsmaterialien (58,3 %) und unzureichende Fortbildungsm&#246;glichkeiten (75 %) als Hauptgr&#252;nde. Die Befragung der Bildungsministerien ergab, dass lediglich zwei Bundesl&#228;nder CPR-Schulungen umfassend umgesetzt hatten, w&#228;hrend sechs L&#228;nder diese in ihre Lehrpl&#228;ne integriert haben.</p>
</sec>
<sec>
<title>Fazit:</title>
<p>Trotz gro&#223;er Unterst&#252;tzung durch Lehrkr&#228;fte verhindern strukturelle Defizite, unzureichende Finanzierung und organisatorische M&#228;ngel eine nachhaltige CPR-Ausbildung an deutschen Schulen. Finanzielle Investitionen, standardisierte Lehrmaterialien und eine bundesweite Koordination sind notwendig, um diese Barrieren zu &#252;berwinden. Ohne konkrete politische und finanzielle Zusagen droht Deutschland ein anhaltender Stillstand in der CPR-Ausbildung, was potenzielle Verbesserungen der OHCA-&#220;berlebensraten erheblich einschr&#228;nkt.</p>

<body>
<p>It is well-established that increasing the willingness of laypeople to perform cardiopulmonary resuscitation (CPR) in Germany could improve survival rates among the approximately 55,000 patients who experience out-of-hospital cardiac arrest (OHCA) annually (<xref ref-type="bibr" rid="B2">Behrens et al., 2020</xref>; <xref ref-type="bibr" rid="B7">Christ et al., 2014</xref>; <xref ref-type="bibr" rid="B14">Schroeder et al., 2017</xref>; <xref ref-type="bibr" rid="B16">Zeymer et al., 2023</xref>). Currently, the 30-day survival rate in Germany, Europe&#8217;s largest economy, is only 10.4%. In contrast, Norway reported a survival rate of 14% in 2021, with 85% of OHCA patients receiving layperson CPR (<xref ref-type="bibr" rid="B3">Bj&#248;rshol et al., 2023</xref>), compared to 51% in Germany (<xref ref-type="bibr" rid="B9">Fischer, 2024</xref>). This 3.6% difference in survival rates corresponds to approximately 2,000 preventable deaths in Germany annually if layperson CPR rates were raised to the Norwegian level.</p>
<p>It is well-documented that CPR education in schools increases the proportion of the population equipped with resuscitation skills (<xref ref-type="bibr" rid="B4">Bohn et al., 2015</xref>). Alongside other factors, school-based CPR education serves as a vital strategy in combating sudden cardiac death, encouraging children to assist others, and fostering enjoyment in learning, with long-term societal benefits (<xref ref-type="bibr" rid="B6">B&#246;ttiger, 2015</xref>). Since 2014, this issue has been addressed through a recommendation from the Standing Conference of Ministers of Education and Cultural Affairs in Germany (<xref ref-type="bibr" rid="B10">Gr&#246;bel, 2014</xref>). However, German states have largely failed to implement CPR education on a widespread basis by 2022, limiting efforts to pilot studies and regional projects (<xref ref-type="bibr" rid="B13">R&#252;cker et al., 2022</xref>).</p>
<p>As of 2023, only the federal states of Mecklenburg-Western Pomerania and Baden-W&#252;rttemberg had achieved comprehensive implementation of school-based CPR education (two out of the 16 federal states). In Brandenburg, a pilot project aimed at implementing CPR education, starting at Grade 7, was launched. Of the initial 33 schools, only five fulfilled their commitment to participate in the project (<xref ref-type="bibr" rid="B12">Kehlert et al., 2024</xref>). While the project demonstrated that the education was worthwhile and students achieved the desired learning outcomes, the high dropout rate was a setback. The reasons remain unclear.</p>
<p>Although numerous studies explore CPR instruction in different age groups, by different instructors (<xref ref-type="bibr" rid="B1">Abelairas-G&#243;mez et al., 2014</xref>; <xref ref-type="bibr" rid="B5">Bohn et al., 2012</xref>; <xref ref-type="bibr" rid="B11">Humbsch et al., 2023</xref>) the appropriate duration, and the structure of the lessons (<xref ref-type="bibr" rid="B14">Schroeder et al., 2017</xref>), only a few authors currently address the sustainable and long-term implementation of such training, as well as the necessary resources and obstacles that need to be overcome. Following the pilot project in Brandenburg, school staff were interviewed about the reasons for the high cancellation rate and potential issues in the process. In addition, the Ministries of Education and the Arts of all 16 federal states were consulted on the current status of implementation. The aim was to identify the underlying problems in the implementation of CPR training in the 16 federal states of Germany from the connections found and to derive potential solutions from these findings.</p>
<sec>
<title>Methods</title>
<sec>
<title>Study Setting and Design</title>
<p>This study is based on interviews with school staff and an inquiry conducted amongst the Ministries of Education from Germany&#8217;s 16 federal states as part of the &#8220;Herzensretter&#8221; study (English: Heart Saver) (<xref ref-type="bibr" rid="B12">Kehlert et al., 2024</xref>). The primary objective was to identify barriers and opportunities for the long-term curricular integration of CPR education at two levels. First, by conducting interviews with teachers from 28 schools that did not implement the project to understand challenges at the school level. Second, surveying the Ministries of Education to examine obstacles in adopting the recommendation of the KMK (Kultusministerkonferenz, English: Standing Conference of the Ministers of Education and Cultural Affairs) at the state level. Based on these findings, the study aims to derive potential solutions for more effective nationwide implementation.</p>
</sec>
<sec>
<title>Interview Study</title>
<p>First, all schools (n = 33) were contacted to determine whether they had conducted the pilot project (<xref ref-type="fig" rid="F1">Figure 1</xref>). Schools were divided into two groups: those that had implemented the project (n = 5) and those that had not (n = 28). Teachers from the group that had not implemented the project were identified as potential participants and were contacted by the research team.</p>

<graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="ijfae-2703_humbsch-g1.png"/>
</fig>
<p>They were invited to participate in an interview about the project. Follow-up interviews were conducted with those that agreed to participate. The interviews were voluntary and were conducted with the designated contact teacher from each non-participating school. The interview questions were specifically developed for this study and pretested with a small group of teachers for clarity and completeness. They included both closed and open-ended questions:</p>
<list list-type="order">
<list-item><p>Should the lessons be taught by the school&#8217;s teachers or external specialists?</p></list-item>
<list-item><p>In your opinion, will resuscitation lessons be taught in your school in the medium term?</p></list-item>
<list-item><p>How many teachers should teach resuscitation lessons?</p></list-item>
<list-item><p>How do you see the need to establish resuscitation lessons in schools? Answer on a five-point Likert scale: very useful, somewhat useful, neutral, somewhat not useful, not useful, don&#8217;t know (no rating).</p></list-item>
<list-item><p>What needs to be done to establish resuscitation lessons?</p></list-item>
</list>
<p>The questionnaire for the interviews, as well as the questions used to survey the ministries, were validated in consultation with school teachers, principals, and first aid instructors to ensure relevance to the study objectives.</p>
</sec>
<sec>
<title>Data Analysis</title>
<p>Responses were recorded and grouped semantically where possible, see <xref ref-type="table" rid="T1">Table 1</xref>. The semantic grouping of questions was carried out by analyzing their content-related similarity and meaning. Related questions are clustered together to form thematic groups. This process enables a structured categorization of the questions and helps identify key topics and recurring patterns within the dataset. Open-ended answers were analyzed qualitatively to identify recurring themes and patterns.</p>

<p>Ethical approval for the underlying &#8220;Herzensretter&#8221; study, which included follow-up interviews with teachers (conducted in this study), was granted by the ethics committee of Charit&#233; Universit&#228;tsmedizin Berlin, Campus Virchow-Klinikum (Application Number EA2/041/20). Further ethical approval was not required for the survey of education ministries, because this present study is a follow-on study from the previous study, using publicly available data.</p>

<sec>
<title>Statistical Analysis</title>
<p>Statistical analysis was applied selectively based on the nature of the data. For categorical variables where comparisons between groups were relevant, such as instructor preference (Question 1), we conducted statistical tests (e.g., chi-square test). For questions aimed at identifying general trends, such as the importance rating of resuscitation training (Question 4) or reported obstacles (Question 5), descriptive statistics were deemed sufficient, as the primary goal was to summarize the responses rather than test specific hypotheses.</p>

<p>Standardized emails containing a predefined questionnaire were sent to the education ministries of all 16 states. Follow-up reminders were sent to non-responding ministries at intervals of two and four weeks.</p>
<p>Responses were reviewed by the research team to ensure consistency and accuracy. Discrepancies or ambiguities were clarified directly with the respective ministries. The collected data were tabulated and comparatively analyzed to highlight differences between states, identifying patterns and challenges.</p>

<title>Results</title>
<p>Teachers from a total of twelve schools participated in the interviews, and their anonymized responses are summarized in <xref ref-type="table" rid="T1">Table 1</xref>. The interview results highlight different perspectives on implementing resuscitation lessons in schools. Regarding the preferred instructors, 50% (6/12) of schools favored their teachers, citing organizational challenges and financial constraints as the reasons for this. In contrast, 25% (3/12) of schools preferred external experts for their specialized knowledge, while 25% (3/12) remained neutral, stating that both options were possible. The chi-square test results in a chi-square statistic of 1.5 and a p-value of approximately 0.472. This indicates that there is no significant deviation from an equal distribution (p &gt; 0.05), meaning the preference for own teachers, external experts, or neutrality does not significantly differ from what would be expected by chance.</p>
<p>The vast majority (91.7% or 11/12 of schools) believed that resuscitation lessons would be introduced in the 7<sup>th</sup> grade, with one school already integrating a full first aid certification program for ninth graders. Most schools agreed that at least two teachers should be responsible for teaching these lessons to ensure effective instruction. On a five-point Likert scale, 41.7% (5/12) of schools rated resuscitation lessons as &#8220;very useful,&#8221; while 50% (6/12) found them &#8220;useful.&#8221; One school did not provide a rating (8.3% or 1/12).</p>
<p>Several challenges were identified including the need for additional time (41.7% or 5/12 of schools), teacher training (75% or 9/12 of schools), better logistical arrangements such as hygiene considerations (33.3% or 4/12 of schools), and improved teaching materials (50% or 6/12 of schools). Some schools specifically mentioned the necessity of dedicated mannequins, videos, pictures, and books to enhance instruction. Additionally, 16.7% (2/12) of schools emphasized the importance of support from school leadership for successful implementation.</p>
<p>The responses to Question 5 (What needs to be done to establish resuscitation lessons?) were categorized into thematic groups and illustrated using a bar chart (<xref ref-type="fig" rid="F2">Figure 2</xref>). The responses given thus represent the expectations of the teachers, which they see as prerequisites for sustainably integrating and implementing resuscitation training in the curriculum. A possible relationship between schools preferring their own teaching staff and those planning to implement the training was examined. However, we found that both those that preferred their own teaching staff and those who wanted external instructors all indicated that they planned to implement resuscitation training in the 7<sup>th</sup> grade, suggesting this preference did not influence the decision to introduce training.</p>

<title>Findings from the survey of Education Ministries</title>
<p>The results of the survey are provided in <xref ref-type="table" rid="T2">Table 2</xref>.</p>
<p>Out of Germany&#8217;s 16 federal states, six (37.5%) reported that resuscitation training is already firmly embedded within their school curricula. In five states (31.25%), integration is currently being planned, while the remaining five (31.25%) had not yet initiated any relevant measures.</p>
<p>When it comes to implementation, only two states (12.5%) have established resuscitation training on a statewide level. In contrast, six states (37.5%) offer such training regionally or through pilot projects, with the long-term goal of expanding coverage. However, half of the states (50%) reported having no comprehensive programs in place.</p>
<p>The majority of states (12 out of 16, or 75%) begin resuscitation training in the 7th grade. Two states (12.5%) have extended this instruction to primary schools, while another two (12.5%) did not provide any information on the grade level at which training begins.</p>
<p>Regarding the duration of training, 13 states (81.25%) follow a standard format of two teaching units. The remaining three states (18.75%) did not specify any details about the duration.</p>
<sec>
<title>Statistical Test</title>
<p>Curriculum Integration vs. statewide Implementation: A chi-square test was conducted to examine the relationship between curriculum integration and nationwide implementation. The result (&#967;&#178; = 5.4, p = 0.067) indicated no significant association (p &gt; 0.05).</p>
</sec>

<sec>
<title>Discussion</title>
<p>The interview results indicate that structural and resource-related deficits present major challenges to implementing resuscitation training in schools. Schools that withdrew from the pilot project, despite initially agreeing to participate, cited insufficient training, a lack of teaching materials, and time constraints as key obstacles. Similarly, teachers emphasized that these limitations make effective instruction difficult. To manage organizational challenges, they suggested having at least two instructors per session to ensure smooth lesson delivery.</p>
<p>Encouragingly, the interviewed teachers demonstrated high motivation and recognized the value of resuscitation training. This was expected, as participating schools had volunteered for the pilot phase. The central issue during the pilot phase of the <italic>Herzensretter</italic> project was not a lack of acceptance among teachers but rather insufficient resources.</p>
<p>The COVID-19 pandemic exposed additional vulnerabilities in the concept. Originally planned for the 2019/2020 school year, the project was significantly disrupted by the pandemic, which led to school closures, teaching interruptions, and staff shortages. Deficiencies in physical infrastructure, such as inadequate ventilation systems, exacerbated the situation.</p>
<p>Funding for the pilot project was also insufficient to ensure sustainable implementation. Although the state provided initial resources including 40 resuscitation mannequins and training sessions for instructors, critical follow-up tasks, including maintenance and cleaning of the mannequins, were not addressed. The long pandemic-induced hiatus meant that trained instructors could not refresh their skills and missed resuscitation sessions have yet to be rescheduled. A lack of accompanying teaching materials and ongoing professional development further hindered sustainable implementation.</p>
<p>The survey of ministries highlighted that these challenges are not isolated. Among the 16 federal states, only six had formally integrated resuscitation training into their curricula, and just two had achieved statewide implementation. Where training is conducted, it generally adheres to the 2014 recommendations of the Standing Conference of the Ministers of Education and Cultural Affairs (KMK), (i.e., two teaching units starting in the 7th grade).</p>
<p>Statistical analysis underscored these findings. A chi-square test showed no significant correlation between curriculum integration and statewide implementation (p = 0.067). This indicates that curriculum integration alone is insufficient to ensure sustainable implementation.</p>
<p>In summary, despite strong support from teachers and the recognized importance of resuscitation training for public health, its implementation is hindered by structural challenges, insufficient funding, and organizational deficiencies. Sustainable adoption requires targeted investments in resources, comprehensive financing, and centralized coordination to support schools in overcoming these obstacles. Additionally, according to the statements made by the teachers in the interviews, standardized teaching materials could represent an improvement.</p>
<sec>
<title>Limitations</title>
<p>The limitations of this study fall into several key areas that may influence the interpretation of the results. First, the study was based on a non-representative sample, as only schools that had voluntarily registered for the previous pilot project were included. This introduces potential bias, as these schools may have higher intrinsic motivation or better infrastructure compared to the average school. Furthermore, interview participation was voluntary, raising the possibility of non-response bias, as schools with limited resources or a critical stance toward the project may have opted out.</p>
<p>Second, the low response rate from schools and late and sparse responses from ministries poses challenges. Sixteen schools did not respond, and not all ministries provided complete answers. This incomplete data could mean that actual barriers and progress remain underreported.</p>
<p>Third, the validity of the interview questionnaire is another consideration. Although the questionnaire was piloted and developed in consultation with experts, it is unclear whether it fully captured all relevant aspects of resuscitation training in schools. Contextual factors such as regional differences in educational infrastructure or specific political frameworks may have been overlooked.</p>
<p>Finally, temporal and logistical constraints presented limitations. Data collection occurred within a restricted time frame, potentially overlooking significant developments, particularly those related to the long-term impacts of the COVID-19 pandemic. This pandemic not only disrupted school capacities but also shifted educational priorities, limiting the generalizability of the findings.</p>

<sec>
<title>Conclusion</title>
<p>Resuscitation training saves lives. It can be effectively implemented by schoolteachers, medical students, physicians, paramedics, and first-aid instructors from aid organizations. Research has already identified the necessary components of these programs, including their frequency, content, and optimal teaching strategies to increase lay resuscitation rates.</p>
<p>Given this robust body of evidence, it is increasingly urgent to address the lack of progress in Germany over the past decade. Tackling the infrastructural issues involved in implementing first-aid training requires acknowledging the &#8220;elephant in the room&#8221;: it will incur costs. We need functional infrastructure, efficient resource allocation, and innovative approaches such as the use of online platforms to deliver CPR training and/or a combination of online and in-person instruction to enhance accessibility and effectiveness. Professional development opportunities and teaching materials are also needed, along with mechanisms for independently measuring implementation. All of this entails costs for both procurement and maintenance.</p>
<p>While the path is long, it is undoubtedly worthwhile. As of 2025, the situation remains largely unchanged, with only two federal states having achieved statewide implementation. It is no longer a question of whether resuscitation training is valuable but how it can be implemented. Embedding it in curricula alone is insufficient. Financial commitment and clear expectations regarding program structure, delivery methods, and resources are essential. After a decade, it is alarming that a greater level of implementation has not been achieved across Germany.</p>
