The outbreak of war in Ukraine has contributed to the largest migration crisis in this part of Europe since the Second World War. In a short period of time, several million refugees of different ages and with different health needs have arrived in Poland. This study aims to assess the health problems of Ukrainian refugees, evaluate the barriers faced by primary care physicians (PCPs), and analyse and evaluate the system solutions available (including the use of modern information technology) to address them. For this purpose, an original questionnaire distributed to PCPs in Poland was created and a literature review of implemented system solutions was conducted. The survey was conducted between the 3rd-10th April 2022-45 days after the outbreak of the war. The survey was repeated between 20th January and February 15, 2023. The survey was completed by 402 physicians who provided health care to refugees at that time. There were 252 respondents in the first stage of the study while 150 PCPs took part in the repeat survey. The findings of the survey revealed that the most common health problems among refugees were infections, regardless of age. The biggest barrier to providing care to refugees was the lack of available medical records and language difficulties. During the first months of the refugee influx in Poland, many - both systemic and grassroot - solutions were implemented to improve the quality of health care for refugees. According to PCPs, the language barrier and the lack of previous medical records are key constraints when providing medical care to refugees. The health needs of refugees and the difficulties in providing care for them require constant monitoring and implementation of appropriate systemic solutions that can reduce the limitations in the daily work of medical staff.

Background: Vaccination is one of the most effective ways of protecting individuals against serious infectious diseases and their fatal consequences. Objectives: The aim of this scoping review was to synthesize data on parental attitudes toward vaccination and identify factors influencing the motivators and barriers to children’s vaccination based on Polish studies. Methods: The scoping review process and reporting were based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScRs) checklist. In the period between January 2014 and July 2024, the following databases were searched for publications: PubMed, Web of Science, Cochrane, Ebsco, and Scholar Google. Results: A total of 1531 potentially relevant records were reviewed, and 30 original publications from research samples collected in Poland were selected. According to the findings, vaccination rates varied between 100% and 70%, with parental acceptance levels for mandatory vaccination ranging from 99% to 65%. Parents most commonly cited the physician, the nurse, and the Internet as their primary sources of vaccination-related information. Moreover, parental primary motivators for vaccinating their children were prevention against infectious diseases, the opinion that vaccines are safe, and the belief that childhood vaccination is right and effective. The major barriers to vaccination were fear of vaccine side effects and the belief that vaccines are ineffective. Parents that were better educated, were of younger age, lived in cities, and had a higher income were much more likely to vaccinate their children. Conclusions: Understanding parental attitudes toward vaccination may help develop an educational program aimed at combating misinformation and increasing childhood vaccination coverage rates.

Obesity management, whether lifestyle-based, pharmacological, or surgical, is frequently associated with gastrointestinal adverse effects (GI AEs) that may impact treatment adherence and patient quality of life. With the increasing use of incretin-based anti-obesity medications (AOMs), they have gained particular clinical relevance. This review aims to explore current evidence on the prevalence, underlying mechanisms, and management strategies for GI AEs associated with obesity therapies, with a particular focus on nausea, diarrhea, constipation, gastroesophageal reflux and cholelithiasis. A search of PubMed and Scopus was conducted for articles published between 2006 and 2025. Eligible studies included randomized controlled trials, observational studies, and narrative or systematic reviews reporting on GI AEs in the context of obesity treatments, especially those involving incretin-based AOMs. Clinical trial data on AOMs indicate that GI AEs are reported in 65–84% of patients treated with liraglutide, semaglutide or tirzepatide, with the most common being nausea and diarrhea. These symptoms are primarily attributed to altered gastric motility and hormone-mediated changes in appetite signaling. Preventive strategies such as slow dose titration, dietary counseling, and supportive medications are commonly recommended to support tolerability and treatment continuation. GI AEs remain a common and often underestimated barrier to effective obesity management. Early recognition and structured management are essential to long-term success. Clinicians should incorporate anticipatory counseling and shared decision-making at treatment initiation to set realistic expectations, optimize tolerability, and support adherence.

Introduction: Antibiotic resistance is a major public health problem in Europe. Most antibiotics are sold only by prescription in Poland, and it is mainly up to physicians to decide whether to start antibiotic treatment. Therefore, we analyzed the factors influencing the prescribing of antibiotics for upper respiratory tract infections by primary care physicians in Poland, attitudes toward antibiotic resistance, and knowledge of the principles of antibiotic use. Methods: We conducted a CAWI (Computer-Assisted Web Interview) survey, carried out using a proprietary survey distributed online. Results: A total of 528 doctors participated in the study. The result of the physical examination and additional tests, as well as the recommendations of scientific societies are the most important in deciding whether to start antibiotic therapy. Patient pressure (p < 0.011) and workload (p = 0.021) significantly influenced the decision to prescribe an antibiotic among primary care physicians and physicians in the course of specialization, who fear of legal consequences (p < 0.001). The habits of other physicians (p < 0.001) working at the same facility appeared to be additionally important. Conclusions: The decision to implement antibiotic therapy in upper respiratory tract infections is influenced by several factors that depend on the doctor (including place of work and seniority) and the patient (clinical symptoms, expectation of antibiotic prescription). The physician’s level of knowledge contributes to reducing antibiotic prescribing. Considering the factors associated with the level of knowledge and awareness, together with a high prevalence of self-medication with antibiotics in Polish population, there is a strong need to design educational interventions aimed at reducing inappropriate antibiotic prescribing and preventing antibiotic resistance in Poland.

Objectives The purpose of the study was to investigate the collaboration between primary care and palliative care physicians, which is key to providing comprehensive care, and to identify potential difficulties and needs in referring patients to palliative care. Methods The study was conducted as an online survey, available to primary care and palliative care physicians. The data collected during the survey were used to compare perceptions of different specialty physicians’ perspectives on various aspects regarding palliative care. Results The results of the study showed significant differences in the assessment of the palliative care services availability (73% of primary care physicians rate it poorly comparing to high rating of 60% by palliative care specialists), as well as disparities between the declarations regarding the criteria used to decide on referral to palliative care (achieving the best quality of life) and the actual referral of patients (primary care physicians are third on the list of specialists referring patients to palliative care). Despite the need for adequate cooperation between family physicians and palliative care physicians, some difficulties were identified, such as primary care physicians’ lack of knowledge of the patient palliative care referral criteria, and financial as well as personnel and palliative care facilities’ limitations, were identified. Conclusions The study confirms the need for better cooperation between primary care physicians and palliative care specialists in Poland. It suggests that educating primary care physicians about palliative care referral criteria can improve the patient referrals accuracy.

Background/Objectives: Chronic kidney disease (CKD) affects 10 to 15% of the world population. Currently, there are no reliable epidemiological data on the prevalence of CKD in Poland. The aim of this study was to determine the prevalence of CKD in the population of high-risk primary health care patients without a prior diagnosis of CKD in the Polish population. Methods: This multicenter retrospective study examined 5100 patients from 28 medical institutions. Patients were eligible for the study if they were 60–75 years old or had a history of the risk factors such as hypertension, kidney disease other than CKD, diabetes, cardiovascular disease, or obesity. The study was carried out in two stages, each of which included a determination of serum creatinine levels along with an estimation of eGFR and a determination of albuminuria in a urine sample. Results: In total, 5100 patients were included in the final analysis. In the univariate analysis, it was found that as age and body mass index values increased, the risk of developing CKD increased; the same correlation was observed when assessing the presence of hypertension, diabetes, or heart failure. In the multivariate analysis, the negative effects of hypertension, age 60–75 years, diabetes, heart failure, cardiovascular diseases, and kidney disease other than CKD on the development of CKD were confirmed. Conclusions: The results indicate that CKD is a significant social problem among the Polish population with risk factors.
