Trends in public perceptions of patient safety during the COVID-19 pandemic: Findings from a repeated cross-sectional survey in Germany, 2019–2023
2025
In recent years, public perceptions of patient safety have evolved significantly, driven by media coverage, healthcare reforms, and greater awareness during the coronavirus disease 2019 (COVID-19) pandemic. The present study aimed to examine trends in public perceptions of patient safety, knowledge and self-efficacy in Germany during this pandemic between 2019 and 2023. A repeated cross-sectional study was conducted, using data from TK Monitor of Patient Safety. TK Monitor of Patient Safety in a nationwide survey assessing public perceptions of safety in medical treatment and diagnosis. Self-reported data were collected annually from a randomly selected sample of 1,000 different adults aged 18 and older residing in Germany. Statistical analyses included descriptive statistics, chi-square tests, and linear regressions for trend analyses. Our results revealed high perceived patient safety risk during the years of the study. Up to one third of respondents considered it very likely or somewhat likely that patients would be harmed when receiving medical treatment in hospital or ambulatory care, with lower perceived levels of risk before the COVID-19 pandemic. Regarding perceived prevalence of preventable adverse events, over half of respondents considered it very likely or somewhat likely that an illness of theirs would be diagnosed incorrectly, or that they would contract a nosocomial infection, at some stage in their lives. The majority of respondents considered themselves overall well informed about patient safety and reported higher levels of self-efficacy with regard to error prevention before and after the pandemic than during it. Given the facts that patient safety remains an important issue and that the German public perceives the level of patient safety risk but also of patient safety knowledge, and self-efficacy as high, actively involving patients in safety initiatives is essential for shaping positive public perception.

Patient safety and climate change: findings from a cross-sectional survey in Germany
2024
Background
Patient safety has become a priority issue in health policy strategies in Germany in the last several years, and is especially important in the era of climate change. This study aimed to assess public perceptions about the patient safety impact of climate change and the demographic and socioeconomic factors influencing patient perception in Germany.
Methods
A cross-sectional study was conducted in Germany in 2023, using data from the TK Monitor of Patient Safety. The TK Monitor of Patient Safety is a national survey of the population on the state of safety in medical care. Self-reported data were collected from 1,000 randomly selected adults living in Germany. Demographic and socioeconomic variables were regressed on climate change perception using an ordinal logistic regression approach.
Results
Our results revealed that half of respondents are concerned about climate change affecting their health and 40% of the respondents would like to have climate-sensitive health counseling by their general practitioner. The results showed that demographic variables, such as gender and age, and socioeconomic variables, such as education level and income, are important factors influencing the perception of climate change-related patient safety risks. However, no association was found between urban/rural residence and patient perception.
Conclusions
Our study highlights patient safety as a public health concern in the era of climate change. The German public appears to view climate change as harmful to patient safety. Our findings also show that it is necessary to carry out diagnoses focused on demographic and socioeconomic factors to determine which aspects should be strengthened through programs aimed at reducing patient safety risks associated with climate change.

Public perceptions of digitalisation and patient safety: a cross-sectional survey in Germany
2025
ObjectivesTo explore perceptions of digitalisation and patient safety from the view of the German general public and related sociodemographic factors.DesignCross-sectional survey.SettingA nationwide survey was undertaken in 2024, using data from the Techniker Krankenkasse (TK) Monitor of Patient Safety. The TK Monitor of Patient Safety is an annual survey of the population on the state of patient safety in medical care.Participants1000 German adults (18 years and older).Primary and secondary outcome measuresOrdinal logistic regression analyses were performed to investigate the associations among sociodemographic factors (age, gender, education and household income) and perceptions on digitalisation and patient safety.ResultsThe majority of respondents expected benefits from digital applications in healthcare. Over half of the respondents (58%) believed that artificial intelligence (AI) can help reduce complications and errors, while 49% of the respondents believed that the use of AI poses serious new risks for the healthcare sector. The results showed that sociodemographic variables are important factors influencing patient safety perceptions of digitalisation and AI. Female, older, less educated and/or lower-income individuals were less likely to perceive benefits from digital care applications and AI.ConclusionsIn our study, the German public appears to view digital technologies and AI as tools both for improving patient safety and as potential risk factors. Our findings also highlight the importance of analysing sociodemographic factors to identify specific disparities in how different groups are affected by digitalisation. Such analysis is essential for developing targeted strategies that mitigate current patient safety risks, ensuring that digital health solutions are equitable and safe across all demographic groups.

Communication
2019
Background
Patient safety is a key target in public health, health services and medicine. Communication between all parties involved in gynecology and obstetrics (clinical staff/professionals, expectant mothers/patients and their partners, close relatives or friends providing social support) should be improved to ensure patient safety, including the avoidance of preventable adverse events (pAEs). Therefore, interventions including an app will be developed in this project through a participatory approach integrating two theoretical models. The interventions will be designed to support participants in their communication with each other and to overcome difficulties in everyday hospital life. The aim is to foster effective communication in order to reduce the frequency of pAEs. If communication is improved, clinical staff should show an increase in work satisfaction and patients should show an increase in patient satisfaction.
Methods
The study will take place in two maternity clinics in Germany. In line with previous studies of complex interventions, it is divided into three interdependent phases. Each phase provides its own methods and data. Phase 1: Needs assessment and a training for staff (
n
= 140) tested in a pre-experimental study with a pre/post-design. Phase 2: Assessment of communication training for patients and their social support providers (
n
= 423) in a randomized controlled study. Phase 3: Assessment of an app supporting the communication between staff, patients, and their social support providers (
n
= 423) in a case-control study. The primary outcome is improvement of communication competencies. A range of other implementation outcomes will also be assessed (i.e. pAEs, patient/treatment satisfaction, work satisfaction, safety culture, training-related outcomes).
Discussion
This is the first large intervention study on communication and patient safety in gynecology and obstetrics integrating two theoretical models that have not been applied to this setting. It is expected that the interventions, including the app, will improve communication practice which is linked to a lower probability of pAEs. The app will offer an effective and inexpensive way to promote effective communication independent of users’ motivation. Insights gained from this study can inform other patient safety interventions and health policy developments.

BackgroundCritical incident reporting systems (CIRS) can be an important tool for the identification of organisational safety needs and thus to improve patient safety. In German primary care, CIRS use is obligatory but remains rare. Studies on CIRS implementation in primary care are lacking, but those from secondary care recommend involving management personnel.ObjectiveThis project aimed to increase CIRS use in 69 practices belonging to a local practice network.MethodsThe intervention consisted of the provision of a web-based CIRS, accompanying measures to train practice teams in error management and CIRS, and the involvement of the network’s management. Three measurements were used: (1) number of incident reports and user access rates to the web-based CIRS were recorded, (2) staff were given a questionnaire addressing incident reporting, error management and safety climate and (3) qualitative reflection conferences were held with network management.ResultsOver 20 months, 17 critical incidents were reported to the web-based CIRS. The number of staff intending to report the next incident online decreased from 42% to 20% of participants. In contrast, the number of practices using an offline CIRS (eg, incident book) increased from 23% to 49% of practices. Practices also began proactively approaching network management for help with incidents. After project completion, participants scored higher in the patient safety climate factor ‘perception of causes of errors’. For many practices, the project provided the first contact with structured error management.ConclusionSpecific measures to improve the use of CIRS in primary care should focus on network management and practice owners. Practices need basic training on safety culture and error management. Continuing, practices should implement an offline CIRS, before they can profit from the exchange of reports via web-based CIRS. It is crucial that practices receive feedback on incidents, and trained network management personnel can provide such support.

Replacement of endoprosthetic implants within a two years follow-up period: a statutory health insurance routine data analysis
2012
Background
The statutory health insurance system embodies a large amount of data on the treatments of their members. Depending on joint, prosthesis type, patient activity and comorbidity, knee and hip replacements can last up to 20 years. Based on statutory health insurance data the main object of this analysis was to investigate how high the early revision rate of replacements actually is.
Methods
The number of replacements in the years 2005 and 2006 has been extracted from the TK database for hip (OPS-Code 5-820, n = 20,875), knee (OPS 5-822, n = 13,466), upper limbs (OPS 5-824, n = 901), and lower limbs (OPS 5-826) replacements. This data has then been related to each consecutive operation (i. e. change or excision of joint endoprosthesis) over a joint-specific observation period of two years.
Results
In 3.7% of the cases joint replacements stood for less than 2 years (hip 3.5%, knee 3.8%, upper limbs 6.5%, and lower limbs 5.5%). There is a significantly positive correlation between the treatment data of the hospitals and the outcome as to low rates of reoperations at early stages. The main reason for short lifetime (76 - 81%) is mechanical failure.
Conclusion
The percentage of joint endoprostheses with significantly short lifetimes has been unexpectedly high. The de facto lifetimes of joint endoprostheses thus often do not match the manufacturers’ information. The authors strongly support the idea of a national endoprosthesis register as such a register could give detailed information on
firstly whether these deficits are due to material defects, osteolysis or dislocation and
secondly which products are mainly affected.

Patient Safety and the COVID-19 Pandemic in Germany: A Repeated Population-Based Cross-Sectional Survey
2022
The coronavirus (COVID-19) has presented Germany with major challenges and has led to concerns about patient safety. We conducted an observational, population-based, nationwide, repeated cross-sectional survey on patient safety in Germany in 2019, 2020, and 2021. Each of the three samples consisted of 1000 randomly recruited adults. Self-reported data via computer-assisted telephone interviews were taken from TK Monitor of Patient Safety. Perceptions, experience, and knowledge relating to patient safety were assessed. The majority of respondents considered medical treatment to involve risks to patient safety. This proportion decreased during the pandemic. The majority also had a high degree of self-efficacy regarding the prevention of medical errors, whereby the percentage that felt well informed with regard to patient safety rose throughout the pandemic. The proportion of persons that suspected they had in the past experienced an error in their treatment remained steady at one third as well as the reported errors. In 2020, 65% of respondents thought health communication with service providers (e.g., extent and comprehensibility of information) remained unchanged during the pandemic, while 35% reported that medical appointments had been cancelled or postponed. This study is the first to assess patient safety from a general population perspective during the coronavirus pandemic in Germany. COVID-19 had a positive impact on perceived patient safety but no impact on suspected and reported errors. Self-efficacy with regard to medical error prevention steadily increased in the general population, and people considered themselves well informed.

Blood glucose testing and primary prevention of diabetes mellitus type 2 - evaluation of the effect of evidence based patient information
2010
Background
Evidence-based patient information (EBPI) has been recognised as important tool for informed choice in particular in the matter of preventive options. An objective, on the best scientific evidence-based consumer information about subthreshold elevated blood glucose levels (impaired fasting glucose and impaired glucose tolerance) and primary prevention of diabetes, is not available yet. Thus we developed a web-based EBPI and aim to evaluate its effects on informed decision making in people 50 years or older.
Methods/Design
We conduct a web-based randomised-controlled trial to evaluate the effect of information about elevated blood glucose levels and diabetes primary prevention on five specific outcomes: (i) knowledge of elevated blood glucose level-related issues (primary outcome); (ii) attitudes to a metabolic testing; (iii) intention to undergo a metabolic testing; (iv) decision conflict; (v) satisfaction with the information. The intervention group receives a specially developed EBPI about subthreshold elevated blood glucose levels and diabetes primary prevention, the control group information about this topic, available in the internet.
The study population consists of people between 50 and 69 years of age without known diabetes. Participants will be recruited via the internet page of the cooperating health insurance company, Techniker Krankenkasse (TK), and the internet page of the German Diabetes Centre. Outcomes will be measured through online questionnaires. We expect better informed participants in the intervention group.
Discussion
The design of this study may be a prototype for other web-based prevention information and their evaluation.

Background
Having shown in a recent randomized controlled trial that evidence-based patient information (EBPI) significantly increased knowledge on primary prevention of diabetes compared to standard patient information, we now investigated interaction between socioeconomic status (SES) and the effect of an EBPI.
Findings
1,120 visitors (aged 40–70 years, without known diabetes) to the “Techniker Krankenkasse” and the “German Diabetes Center” websites were randomized. The intervention group received a newly developed on-line EBPI, the control group standard on-line information. The primary outcome measure was knowledge, classified as “good/average/poor”. We analyzed associations of knowledge with socioeconomic variables (education, vocational training, employment, subjective social status) combined with intervention effect including interactions, adjusted for possible confounding by knowledge before intervention, self–reported blood glucose measurements, blood pressure, blood lipid levels, age and gender. Logistic regression models were fitted to the subpopulation (n = 647) with complete values in these variables.
Education (high vs. low) was significantly associated with knowledge (good vs. average/poor); however, there was no significant interaction between education and intervention. After adjustment, the other socioeconomic variables were not significantly associated with knowledge.
Conclusions
Socioeconomic variables did not significantly change the effect of the intervention. There was a tendency towards a lower effect where lower educated individuals were concerned. Possibly the power was too low to detect interaction effects. Larger studies using SES-specific designs are needed to clarify the effect of SES. We suggest considering the socioeconomic status when evaluating a decision aid, e.g. an EBPI, to ensure its effectiveness not only in higher socioeconomic groups.
