Introduction
According to Polish guidelines futile therapy refers to medical interventions that artificially maintain organ function in patients without a realistic prospect of achieving goals of care. Such practice prolongs patients’ suffering without any benefit and is widely considered a medical and ethical error (Kübler et al. Reference Kübler, Siewiera and Durek2014). However, Poland is characterized by particularly low incidence of life-sustaining treatment limitations compared to other European countries (Guidet et al. Reference Guidet, de Lange and Boumendil2020; Wernly et al. Reference Wernly, Rezar and Flaatten2022). The precise opinions and sentiments of Polish intensive care clinicians regarding end-of-life and futile care remain unknown.
The main aim of the study was to conduct the questionnaire study to evaluate the approach of Polish medical personnel to the problem of futile treatment in the ICUs.
Materials and methods
The electronic questionnaire was administered to participants of the intensive care conference ‘Forum Intensywnej Terapii’ held in April 2023. The congress gathered clinicians practicing intensive care across the whole country. Roughly 700 participants participated in the conference. The questionnaire consisted of 10 questions regarding goals of care, communication between physicians and patients or patients’ families, futile treatment protocol, as well as baseline data (country, region, gender, specialty, work experience, type of hospital).
The results were collected anonymously. The statistical analysis was conducted with SPSS version 29. The chi-squared test was conducted when comparing the responses between respondents with shorter (<10 years) and longer (>10 years) work experience. P-value of 0.05 was considered a threshold for statistical significance. In post-hoc assessments, residual analysis was used with Bonferroni correction for multiple comparison adjustment.
Results
Overall, 354 questionnaires were collected, corresponding to a response rate of approximately 50%. The detailed breakdown of participants’ characteristics is summarized in Table 1. We present questions asked in Table 2.

1 Multiple choice possible
Question 1. In your opinion, should we talk to patients about end-of-life care and futile treatment?
The vast majority (98.5% of respondents) stated that talking to patients about goals of care/futile treatment is important in practice, with less than 2% thinking otherwise (Table 3).

Question 4. Do you find it difficult to discuss futile treatment with the patient, even if you consider it important?
Question 5. Do you find it difficult to discuss futile treatment with the patient’s family, even if you consider it important?
51.2% of participants reported discomfort when discussing end-of-life care topics with patients while 48.8% had difficulty talking to their families, Respondents with longer work experience significantly more frequently reported having no difficulties (Tables 6 and 7].

Question 7. What could be the reasons for not adhering to the guidelines and the futile treatment protocol? (multiple choice question)
Fear of legal consequences (61.9%), fear of family reactions (55.6%) and lack of proper knowledge (39.3%) were the leading causes for protocol implementation hesitancy. The participants with shorter work experience were significantly more likely to point to lack of knowledge and time constraints (Table 9).

Question 8. In your opinion, which initiatives could expand clinicians’ knowledge about futile treatment? (multiple choice question)
Implementation of the futile therapy protocol as a standard hospital procedure and its legal recognition were most frequently indicated as possible means of increasing the physicians’ knowledge of the existing protocol. Respondents with shorter work experience more frequently pointed to usefulness of internal courses in the ICU and discussions at medical conferences (Table 10).

Discussion
The topic of futile treatment is a contentious issue that has recently gained increasing recognition among healthcare professionals. According to the literature, approximately 80–90% of ICU physicians have already practiced withholding or withdrawing therapy (Cardoso et al. Reference Cardoso, Fonseca and Pereira2003; Giannini et al. Reference Giannini, Pessina and Tacchi2003; Kübler et al. Reference Kübler, Adamik and Lipinska-Gediga2011). Our respondents widely acknowledged the importance of discussing futile treatment with patients and their relatives.
However, many clinicians admit administering or witnessing futile treatment for a variety of reasons (Huynh et al. Reference Huynh, Kleerup and Wiley2013). Several guidelines regarding adequate end-of-life care in ICUs have been introduced to support physicians facing ethical dilemmas (Kesecioglu et al. Reference Kesecioglu, Rusinova and Alampi2024). Polish guidelines recommend implementing a protocol for documenting decisions on withholding or withdrawing life-sustaining therapies, while ensuring the continuation of palliative and comfort care. (Kübler et al. Reference Kübler, Siewiera and Durek2014).
Recently, considerable attention has been devoted in the Polish medical community to the issue of perceived overzealous treatment, futile care or end-of-life care. These terms are sometimes (and potentially inappropriately) used interchangeably. The COVID-19 pandemic has caused renewed discussion regarding these phenomena as well as the implications of limited ICU resources (Zadi et al. Reference Zadi, Tavani and Behshid2024). Poland participated in both Very Old Intensive Patients studies, which addressed limitations of treatment (Flaatten et al. Reference Flaatten, De Lange and Morandi2017; Guidet et al. Reference Guidet, de Lange and Boumendil2020). Several national conferences held panels dedicated to the topic of futile treatment. This issue has been also explored by experts in other populations, including pediatric ICU patients (Bartkowska-Śniatkowska et al. Reference Bartkowska-Śniatkowska, Byrska-Maciejasz and Cettler2021) and patients in internal medicine wards (Szczeklik et al. Reference Szczeklik, Krajnik and Pawlikowski2023). The recent novelization of the Polish Code of Medical Ethics introduced a new paragraph specifically prohibiting futile treatment (Alichniewicz and Alichniewicz Reference Alichniewicz and Alichniewicz2024).
Despite those efforts, there is still much to be learned and done. Several studies identified Poland as a country with comparatively low prevalence of treatment limitations (including withdrawal and withholding). In a multicenter study of older patients in the European ICUs, 19.8% older patients in Poland were subjected to some form of treatment limitation compared to 34.4% in the overall European sample (Guidet et al. Reference Guidet, de Lange and Boumendil2020). Polish clinicians limit life-sustaining treatment less frequently than their Scandinavian counterparts (Siewiera et al. Reference Siewiera, Tomaszewski and Piechocki2019). Our survey supports this observation: although most clinicians were aware of the protocol and recognized its importance, they admitted to never or only rarely using it.
Our study attempted to identify barriers to implementing the existing professional protocol. The most frequently reported obstacle was the fear of legal consequences. In a survey of Polish nurses, the fear of legal consequences was also a leading reason to continue what was perceived as futile therapy. (Damps et al. Reference Damps, Gajda and Stołtny2022). This sentiment is understandable, as futile treatment is virtually absent from the Polish legal framework. Although numerous legal experts believe that the Polish law does support limitations of futile treatment, this is never explicitly stated in the Polish legal documents (Szeroczyńska Reference Szeroczyńska2013). Moreover, Poland lacks a ‘no-fault’ rule, and a physician suspected of medical error can be prosecuted based on the Penal Code (Bargiel and Sułkowski Reference Bargiel and Sułkowski2023). Introducing an act of law dedicated to the issue, similarly to the German and French solutions (Graw et al. Reference Graw, Spies and Wernecke2012; Lesieur et al. Reference Lesieur, Leloup and Gonzalez2015), might significantly improve clinicians’ confidence when approaching end-of-life care ethical problems, especially the issue of futile treatment. The impact of legal frameworks on ethical decision-making in ICUs has been emphasized in European guidelines on limitations of treatment in the ICUs (Kesecioglu et al. Reference Kesecioglu, Rusinova and Alampi2024).
Another major factor highlighted by respondents was fear of the patient’s family objections. This is less modifiable but aligns with findings from other surveys. More than half of Polish nurses reported fear of being accused of malpractice by a patient’s family as a reason for continuing futile treatment (Damps et al. Reference Damps, Gajda and Stołtny2022). It is worth noting that, in addition to proper legislation and hospital procedures, effective communication with family along with psychosocial and spiritual support, contributes to better cooperation and mutual understanding between the health care team and relatives during end-of-life discussions (Woźnica-Niesobska et al. Reference Woźnica-Niesobska, Goździk and Śmiechowicz2020). One study found out that prognostic communication, documentation of DNR orders and limitations of treatment, and social worker support positively influenced the deceased patients’ relatives’ satisfaction with ICU care (Chou et al. Reference Chou, Huang and Hu2022). At the same time, it is generally acknowledged that physicians are not obliged to follow relatives’ wishes in every case by prolonging treatment deemed futile and unethical (Szeroczyńska Reference Szeroczyńska2013). Such situations, however, may lead to conflicts arising from differing perceptions of what constitutes futility.
In our study, respondents with less work experience reported feeling less comfortable discussing end-of-life care with patients and their relatives and indicated that a lack of knowledge may underlie the non-implementation of the futile treatment protocol. This association between lower professional experience and greater difficulty in addressing futility is consistent with an American study, which found that intensive care fellows differed significantly from more experienced clinicians in their assessment of medical futility (Neville et al. Reference Neville, Wiley and Holmboe2015). Simultaneously a questionnaire study of Polish medical students found that even though most Polish students heard about futile treatment, only 39% could define it properly (Pełczyński et al. Reference Pełczyński, Karbowiak and Ziembicki2023). These findings along with our study point out the necessity of putting more focus on the topic of futile treatment in Polish medical education.
Limitations
Our study has some limitations. The questionnaires were filled by voluntary respondents, which might increase the risk of omitting physicians who were not familiar with the concept of futile therapy or unwilling to state their opinion. Due to our questionnaire distribution method, it was not possible to calculate the exact response rate.
Conclusions
Even though there is significant awareness among Polish clinicians regarding futile treatment and end-of-life care/protocol in ICUs, there is still a significant room for improvement regarding knowledge of and implementation of guidelines for limitations of treatment in situations deemed futile, especially among clinicians with shorter work experience. Our study underlines the need for optimizing legal and formal frameworks allowing open and transparent discussion about different aspects of end-of-life care.
