[Cancer screening in Germany: availability and participation]

Migration background and use of preventive healthcare services: Findings of the German Ageing Survey

BACKGROUND

This study aimed to investigate the relationship between migration background and the utilization of preventive healthcare services.

METHODS

Cross-sectional data from wave 5 in the year 2014, with a sample size of 7,684 individuals, were extracted from the nationally representative German Ageing Survey. The survey included community-dwelling individuals aged 40 years and above, with migration background serving as the primary independent variable. The outcomes measured included participation in cancer screenings, flu vaccinations, and routine health check-ups. Multiple logistic regressions were used to examine the association between migration background and preventive healthcare services.

RESULTS

Regressions showed that the presence of a migration background with personal migration experience (compared with not having a migration background) was associated with a lower likelihood of using preventive healthcare services. More precisely, compared to individuals not having a migration background, individuals with a migration background and personal migration experience had a lower likelihood of routine health check-ups (OR = 0.76, 95% CI: 0.61 to 0.95), flu vaccinations (OR = 0.75, 95% CI: 0.59 to 0.95) and cancer screenings (OR = 0.71, 95% CI: 0.57 to 0.89). In contrast, there was no significant association between the presence of a migration background without personal migration experience (compared with not having a migration background) and the use of preventive healthcare services.

CONCLUSION

In conclusion, results showed differences between individuals without migration background and individuals with migration background (and with personal migration experience) in terms of using preventive healthcare services. It may be helpful to specifically address individuals with migration background (and with migration experience) in terms of using preventive healthcare services.

[Determinants of the utilization of cancer screening among older adults in Saxony-Anhalt-What is the influence of health literacy?]

BACKGROUND

In order to preserve health and thus social participation, it is important for older people to make health-related decisions, such as those regarding the use of a secondary prevention service like cancer screening. National and international studies show that various predictors determine cancer screening participation. The aim of this study is to determine the cancer screening utilization of older people in a structurally weak region.

METHODS

In 2021, a cross-sectional study in each of two urban and rural communities in Saxony-Anhalt surveyed individuals aged 55 years and older about determinants, reasons, and barriers to preventive service use (n = 954). Binary logistic regression analysis is used to analyze determinants of cancer screening use.

RESULTS

Three quarters of the study population (76.6%) self-reported participating in a cancer screening service at least once. The multivariable analyses demonstrate factors that influence the utilization of cancer screening. Age, partial knowledge on cancer screening, cancer screening as a benefit offered by a statutory health insurances' bonus program, experience with cancer in the immediate environment, thoughts about one's own health, and the feeling of security that participation gives are factors that significantly influence the use of cancer screening. Descriptively, the physician's recommendation is the strongest factor for participation.

CONCLUSION

The analyses show that cancer screenings are generally well received by older people in Saxony-Anhalt, but participation in them is not related to health literacy. In keeping with the National Cancer Plan, older people should generally be supported in making an informed decision, for example, through target-group-specific physician education.

Emergency resection is an independent risk factor for decreased long-term overall survival in colorectal cancer: a matched-pair analysis

BACKGROUND

Colorectal cancer is one of the most common malignant neoplasms worldwide. Up to 30% of the patients present in an emergency setting despite an established screening program. Emergency colorectal resection is associated with increased mortality and morbidity as well as worse oncological outcome. This study aims to analyze the impact on tumor recurrence and survival in patients with an emergency colorectal resection, independent of sex, age, and tumor stage.

METHODS

Patients, who underwent an oncological resection for colorectal cancer at the Medical University of Innsbruck, Department of Visceral, Transplant and Thoracic Surgery, between January 2003 and December 2018 were analyzed retrospectively and screened for emergency resections. Matched pairs were formed to analyze the impact of emergency operations on long-term outcomes, considering tumor stage, sex, and age, comparing it with elective patients.

RESULTS

In total, 4.5% out of 1297 patients underwent surgery in an emergency setting. These patients had higher UICC (Union internationale contre le cancer) stages than elective patients. After matching the patients for age, sex, and tumor stage, emergency patients still had higher mortality. The incidence of recurrence was higher (47.5% vs. 25.4%, p = 0.003) and the 5-year overall survival decreased (35.6% vs. 64.4%, p < 0.001) compared to the matched patients with elective resection. Correcting for 90-day mortality still a reduction in the 5-year overall survival was demonstrated (44% vs. 70%, p = 0,001). The left-sided colon tumors were more common in the emergency group (45.8% vs. 25.4%, p = 0.006) and the rectal tumors in the elective one (21.2% vs. 3.4%, p = 0.002).

CONCLUSION

Patients undergoing emergency resection for colorectal cancer have a decreased tumor-specific and overall survival compared to patients after elective resection, independent of age, sex, and tumor stage, even after correcting for 90-day mortality. These findings confirm the importance of colorectal cancer awareness and screening to reduce emergency resections.

Patient Embeddings From Diagnosis Codes for Health Care Prediction Tasks: Pat2Vec Machine Learning Framework

BACKGROUND

In health care, diagnosis codes in claims data and electronic health records (EHRs) play an important role in data-driven decision making. Any analysis that uses a patient's diagnosis codes to predict future outcomes or describe morbidity requires a numerical representation of this diagnosis profile made up of string-based diagnosis codes. These numerical representations are especially important for machine learning models. Most commonly, binary-encoded representations have been used, usually for a subset of diagnoses. In real-world health care applications, several issues arise: patient profiles show high variability even when the underlying diseases are the same, they may have gaps and not contain all available information, and a large number of appropriate diagnoses must be considered.

OBJECTIVE

We herein present Pat2Vec, a self-supervised machine learning framework inspired by neural network-based natural language processing that embeds complete diagnosis profiles into a small real-valued numerical vector.

METHODS

Based on German outpatient claims data with diagnosis codes according to the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10), we discovered an optimal vectorization embedding model for patient diagnosis profiles with Bayesian optimization for the hyperparameters. The calibration process ensured a robust embedding model for health care-relevant tasks by aggregating the metrics of different regression and classification tasks using different machine learning algorithms (linear and logistic regression as well as gradient-boosted trees). The models were tested against a baseline model that binary encodes the most common diagnoses. The study used diagnosis profiles and supplementary data from more than 10 million patients from 2016 to 2019 and was based on the largest German ambulatory claims data set. To describe subpopulations in health care, we identified clusters (via density-based clustering) and visualized patient vectors in 2D (via dimensionality reduction with uniform manifold approximation). Furthermore, we applied our vectorization model to predict prospective drug prescription costs based on patients' diagnoses.

RESULTS

Our final models outperform the baseline model (binary encoding) with equal dimensions. They are more robust to missing data and show large performance gains, particularly in lower dimensions, demonstrating the embedding model's compression of nonlinear information. In the future, other sources of health care data can be integrated into the current diagnosis-based framework. Other researchers can apply our publicly shared embedding model to their own diagnosis data.

CONCLUSIONS

We envision a wide range of applications for Pat2Vec that will improve health care quality, including personalized prevention and signal detection in patient surveillance as well as health care resource planning based on subcohorts identified by our data-driven machine learning framework.

Making colonoscopy-based screening more efficient: A "gateopener" approach

Screening colonoscopy for early detection and prevention of colorectal cancer (CRC) is mostly used inefficiently. Here, we assessed the potential of an innovative approach to colonoscopy-based screening, by use of a single, low threshold fecal immunochemical test (FIT) as a "gateopener" for screening colonoscopy. Using COSIMO, a validated simulation model, we modeled scenarios including either direct invitation to screening colonoscopy or an alternative approach involving mailing a single ("gateopener") FIT along with an invitation to colonoscopy contingent on a FIT value above a low threshold yielding a 50% positivity rate (ie, every other pretest will be positive). Under plausible assumptions on screening offer adherence, we found that such "gateopener screening" (use of screening colonoscopy contingent on a positive, low threshold gateopener FIT) approximately doubled cancer detection rates vs conventional screening. In those spared from screening colonoscopy due to a negative gateopener FIT pretest, numbers needed to screen were 10-times higher vs those for individuals with a positive FIT, peaking in >2000 and >3800 (hypothetically) needed colonoscopies to detect one case of cancer in men and women, respectively. Gateopener screening resulted in 42%-51% and 59%-65% more prevented CRC cases and deaths, respectively. In summary, by directing colonoscopy capacities to those most likely to benefit, offering screening colonoscopy contingent on a "gateopener" low-threshold FIT would substantially enhance efficiency of colonoscopy screening.

Barriers to access cancer‐related services for men in high‐income countries: A narrative review looking beyond socioeconomic disadvantages

Introduction

Cancer screening programs are routinely available in high‐income countries, but participation rates are low, especially among men. This narrative review aims to identify male‐specific access barriers to cancer‐related healthcare in high‐income countries that offer statutory insurance/subsidized health care.

Methods

We searched PubMed, Science Direct, and Web of Science for peer‐reviewed journal articles published within the past 10 years on cancer healthcare access, help‐seeking behavior, and men. Step‐wise screening of title, abstract, and full text resulted in 23 studies that fit the selection criteria for findings in high‐income countries. The results were analyzed descriptively using qualitative thematic synthesis.

Results

In the reviewed studies, barriers for men in accessing cancer‐related healthcare offers could be broadly categorized under sociocultural norms, personal behaviors, and structural problems. The most common barriers were related to sociocultural influences and included notions of masculinity, distrust in the medical system, and personnel/social commitments. Major personal barriers included fear of getting cancer or screening methods, lack of awareness about cancer, and problems in communication with healthcare professionals. Accessibility and lack of insurance were reported as common structural barriers.

Conclusions

The reluctance of men in approaching medical help was rooted in sociocultural norms of traditional masculinity with direct and indirect consequences such as fear, lack of awareness, distrust of medical personnel, and problems in communicating with healthcare professionals. Gender‐specific, male‐oriented information via digital, anonymous interventions may be helpful for increasing participation of men in cancer care.

Regional inequalities of tumour size at diagnosis in Germany: An ecological study in eight federal states

There is growing recognition of the importance of the residential environment for early detection of cancer. However, few studies have investigated area socioeconomic deprivation, social capital, and rurality in combination. Therefore, we aimed to estimate mutually adjusted associations of these characteristics with tumour size at diagnosis in Germany. We included incident cases of female breast cancer, colorectal cancer, malignant melanoma, uterine cancer, and male bladder cancer, collected by the cancer registries of eight German federal states between 2010 and 2014. Using information on T status, we defined an advanced tumour size for each cancer type. Sex-specific mutually adjusted associations of area socioeconomic deprivation, social capital, and rurality with advanced tumour size and variance partition coefficients were estimated in multilevel logistic regression. Missing data of the outcome were addressed by multiple imputation. Overall, 386,223 cases were included in this analysis. High area socioeconomic deprivation was associated with advanced tumour size at diagnosis of colorectal cancer and malignant melanoma. For malignant melanoma, low social capital was associated with an advanced tumour size among females and males, while a rural settlement structure was associated with advanced tumour size among males only. Since meaningful general contextual effects were found for malignant melanoma, our results underscore that the context of an area is an important predictor of melanoma tumour size. Secondary prevention programs for this cancer type should target areas with high area socioeconomic deprivation, low social capital, and a rural settlement structure in order to reach those most vulnerable.

Krebsrisiko bei Prädiabetes und Typ-2-Diabetes mellitus

Krebs ist nun die führende Todesursache bei Typ-2-Diabetes mellitus (T2D). Prädiabetes und T2D erhöhen das Risiko für bestimmte Tumoren. Zu den Prädiabetes- bzw. T2D-assoziierten Malignomen zählen gastrointestinale, gynäkologische, urologische und endokrine Karzinome aber auch Leukämien. Prädiabetes und T2D bedingen eine 1,2- bis 2,7-fach erhöhte Krebssterblichkeit. Zugrundeliegende Mechanismen der Assoziation zwischen T2D und Krebs beinhalten die chronische Hyperglykämie, einen chronischen systemischen Entzündungszustand, oxidativen Stress, Dyslipidämie, die Insulinresistenz sowie chronisch erhöhte Spiegel von insulin-like growth factor 1 (IGF-1) und von Insulin. Eine dauerhafte Gewichtsreduktion kann das Krebsrisiko adipöser T2D-Patienten signifikant senken. Ein gesunder Lebensstil und die regelmäßige Teilnahme an Vorsorgeuntersuchungen sind wichtig und können die Krebsmortalität von Diabetespatienten erheblich verringern.

Evaluation of prevention behaviour and its influencing factors with respect to cancer screening

Purpose

Every year, about 4.6 million people are diagnosed with cancer in Europe. However, based on preclinical changes and using appropriate examination procedures certain cancers can be detected in symptom-free patients at an early stage and treatment initiated.

In Germany, various cancer screening examinations are currently offered to the relevant age groups and sexes free of charge. Participation rates are affected by a number of factors and barriers. The study aimed at identifying potential obstacles and barriers to uptake, taking into account demographic and socio-economic variables.

Materials and methods

Data collection was conducted in the context of routine examination appointments at the City of Kiel Occupational Health Department from September 2013 to September 2014 using an anonymised questionnaire. In addition to recording socio-demographic data and tobacco consumption, the questionnaire also catalogued participation in statutory health insurance cancer screening examinations using the “stages of change” from the Transtheoretical Model. Eight potential barriers to participation were recorded.

Results

The results are based on 718 completed questionnaires. It was found that women, older age, and non-smoking status were associated with a higher probability of participating in cancer screening. It was also found that various barriers affecting (regular) participation were perceived significantly different according to the individual stages of change. This influence of the stages was moderated by gender.

Conclusion

The results showed interesting trends in the different barriers and how they are influenced by socioeconomic factors and the stages of change. Especially the stages require different gender-specific approaches to mobilisation for cancer screening.

Prevalence of abnormal Pap smear results in inflammatory bowel disease: a prospective study

PURPOSE

Development of malignancy is a pending threat for patients with inflammatory bowel disease (IBD). Aim of this study was to analyze cervical dysplasia and infection with human papilloma virus (HPV) in patients with IBD.

METHODS

This was a prospective, single center cohort study in Germany. Consecutive IBD patients admitted to the Department of Gastroenterology were sent to Gynecology, where a questionnaire was answered and gynecological examinations including a smear for cytology and HPV were taken. Participants of a general screening program constituted controls. Descriptive statistics, 95% confidence intervals and odds ratios were calculated.

RESULTS

A total of 101 patients were recruited of which 99 patients participated. Analysis showed a significant (p = 0.05) difference between the prevalence of abnormal smears in patients with (22%) and without (6%) immunosuppressive therapy, while the latter had cervical abnormalities comparable with healthy controls (5%). All immunosuppressants showed similarly high risks for abnormal smear results. Only 11/99 (11%) patients had positive high-risk HPV tests, which is comparable with general population.

CONCLUSION

The prevalence of abnormal cervical smears is higher in IBD patients compared to healthy individuals, but the difference is confined to patients with IBD and immunosuppressive therapy. Annual screening is advisable.

Genomic Risk Factors for Cervical Cancer

Cervical cancer is the fourth common cancer amongst women worldwide. Infection by high-risk human papilloma virus is necessary in most cases, but not sufficient to develop invasive cervical cancer. Despite a predicted genetic heritability in the range of other gynaecological cancers, only few genomic susceptibility loci have been identified thus far. Various case-control association studies have found corroborative evidence for several independent risk variants at the 6p21.3 locus (HLA), while many reports of associations with variants outside the HLA region remain to be validated in other cohorts. Here, we review cervical cancer susceptibility variants arising from recent genome-wide association studies and meta-analysis in large cohorts and propose 2q14 (PAX8), 17q12 (GSDMB), and 5p15.33 (CLPTM1L) as consistently replicated non-HLA cervical cancer susceptibility loci. We further discuss the available evidence for these loci, knowledge gaps, future perspectives, and the potential impact of these findings on precision medicine strategies to combat cervical cancer.

Socioeconomic deprivation and cancer survival in a metropolitan area: An analysis of cancer registry data from Hamburg, Germany

Background

Few studies have investigated socioeconomic inequalities within cities. Yet, such analyses are particularly important given the increasing international trend to urbanization. Here we investigated area-based socioeconomic inequalities in cancer survival in Hamburg, a port city in the North of Germany (population: 1.84 million people).

Methods

Patients with a diagnosis of colorectal, lung, female breast, and prostate cancer in 2004–2018 (follow-up until 31.12.2018) and registered in the Hamburg cancer registry were included. Area-based socioeconomic deprivation on urban district level was assigned to the patients and grouped in five quintiles. Relative survival in 2014–2018 was calculated using the period approach. Trend analyses between 2004 and 2018 were conducted. Relative excess risks adjusted for age and stage were computed with model-based period analyses.

Findings

For the 73,106 included patients, age-standardized 5-year relative survival in 2014–2018 decreased with increasing deprivation with significant differences between the most and least deprived group of 14·7 (prostate), 10·8 (colorectal), 8·0 (breast), and 2·5 (lung) percent units. Standardization by cancer stage decreased the difference for prostate cancer to 8·5 percent units and for breast cancer to 3·6 percent units but had only a minor effect for colorectal and lung cancer. Similar socioeconomic inequalities were already present in 2004–08.

Interpretation

Strong socioeconomic inequalities in cancer survival were observed in Hamburg, which could be partly explained by differences in the stage distribution. Further research including information on screening participation as well as information on cancer care are important to further understand and finally overcome these inequalities.

Massive uterine fibroid: a diagnostic dilemma: a case report and review of the literature

Background

Fibroids of the uterus are the most common benign pelvic tumors in women worldwide. Their diagnosis is usually not missed because of the widespread and well-established use of ultrasound in gynecological clinics. Hence, the development of an unusually large myoma is a rare event, particularly in first-world countries such as Germany. It is even more uncommon that a myoma is misdiagnosed as a dietary failure.

Case presentation

Herein, we report the case of a Caucasian woman with a giant fibroid that reached a size of over 50 cm, growing slowly over the past 15 years, and was misdiagnosed as abdominal fat due to weight gain. We aim to discuss the factors that lead to the growth of such a huge tumoral mass, including misdiagnosis and treatment, and the psychological impact. Through this case, we intend to increase the awareness among general physicians and gynecologists. Although menstrual disorders incorporate several pathologies, adequate assessment remains the primary responsibility of health care providers. A literature review revealed approximately 60 cases of giant uterine fibroids.

Conclusion

The use of clinical and diagnostic devices, especially ultrasound, in this case, is indispensable. In conclusion, the growth of a giant fibroid can have disastrous effects on a woman’s health, including surgical trauma and psychological issues.

[Intelligent early prostate cancer detection in 2021: more benefit than harm]

Prostate-specific antigen (PSA) is used for early detection of prostate cancer which represents the most frequent cancer diagnosed in men in Germany and Europe. Results of the largest screening trials revealed that PSA testing reduces the incidence of locally advanced and metastatic prostate cancer and shows an effect on cancer-specific mortality. However, since early diagnosis also results in overdiagnosis and overtreatment of insignificant cancers with associated morbidities, there is a need for a more individualized and risk-tailored modern strategy. The PSA at baseline is an important part of this strategy although the German Federal Joint Committee declined its financial coverage by health insurances. Available validated instruments should accompany the baseline PSA to optimize detection of clinically significant prostate cancer.

Intention for Screening Colonoscopy among Previous Non-Participants: Results of a Representative Cross-Sectional Study in Germany

Early detection of colorectal cancer has the potential to reduce mortality at population level. Colonoscopy is the preferred modality for colon cancer screening and prevention, but attendance rates are low. To exploit colonoscopy's preventive potential, it is necessary to identify the factors influencing uptake, especially among previous non-participants. This analysis of cross-sectional data involved 936 non-participants in screening colonoscopy aged 55 years or older in Germany. Differences between non-participants with and without future participation intentions were investigated in terms of socio-demographic factors, health status, attitudes and beliefs, and medical counselling. Logistic regression models were fitted to estimate associations between intention to participate and selected factors. Intention to participate was lower among women than among men. For both genders, intention to participate was positively associated with younger age. For women, higher socioeconomic status and counselling were positively associated with intention to participate. Men showed a positive association with favouring joint decision-making. The results draw attention to starting points for improving acceptance of and participation in screening colonoscopy. This includes good medical counselling and successful physician-patient communication, for which the information and communication skills of both medical professions and the general public should be strengthened. Gender differences should be considered.

Colonoscopy and polypectomy: beside age, size of polyps main factor for long-term risk of colorectal cancer in a screening population

PURPOSE

Despite national and international guideline recommendations, few studies have been conducted to estimate the impact of colonoscopy screening on long-term colorectal cancer incidence. Aim of this study was to determine the long-term impact of a full colonoscopy with polypectomy on colorectal cancer incidence in a large screening population.

METHODS

In this prospective observational cohort study, a total of 10,947 colonoscopy screening participants from within the scope of the Munich Cancer Registry were consecutively recruited from participating gastroenterology practices and their subsequent colorectal cancer incidence assessed. Predictive factors associated with colorectal cancer were also evaluated in univariate and multivariate analyses.

RESULTS

After a median follow-up of 14.24 years (95% CI [14.21-14.25]), 93 colorectal cancer cases were observed. This is equivalent to a truncated age-standardized rate of 69.0 (95% CI [43.3-94.7]) for male and 43.4 (95% CI [29.4-57.5]) for female participants (≥ 50 years at colonoscopy). The ratio of this observed to the expected rate from cancer registry data showed a 67% decrease in colorectal cancer incidence in the male and 65% in the female participants (p < 0.0001). In multivariate analysis of screening patients, age at screening (p < 0.0001) was the main predictive factor for colorectal cancer. In the subgroup with positive polyp findings, age (p < 0.0001) and the polyp size (p = 0.0002) were associated with colorectal cancer.

CONCLUSION

These results underline the significance of a full colonoscopy screening combined with polypectomy in reducing the total disease burden of colorectal cancer.

Divergent Patterns and Trends in Breast Cancer Incidence, Mortality and Survival Among Older Women in Germany and the United States

Background: Breast cancer treatment has changed tremendously over the last decades. In addition, the use of mammography screening for early detection has increased strongly. To evaluate the impact of these developments, long-term trends in incidence, mortality, stage distribution and survival were investigated for Germany and the United States (US). Methods: Using population-based cancer registry data, long-term incidence and mortality trends (1975–2015), shifts in stage distributions (1998–2015), and trends in five-year relative survival (1979–2015) were estimated. Additionally, trends in five-year relative survival after standardization for stage were explored (2004–2015). Results: Age-standardized breast cancer incidence rates were much higher in the US than in Germany in all periods, whereas age-standardized mortality began to lower in the US from the 1990s on. The largest and increasing differences were observed for patients aged 70+ years with a 19% lower incidence but 45% higher mortality in Germany in 2015. For this age group, large differences in stage distributions were observed, with 29% (Germany) compared to 15% (US) stage III and IV patients. Age-standardized five-year relative survival increased strongly between 1979–1983 and 2013–2015 in Germany (+17% units) and the US (+19% units) but was 9% units lower in German patients aged 70+ years in 2013–2015. This difference was entirely explained by differences in stage distributions. Conclusions: Overall, our results are in line with a later uptake and less extensive utilization of mammography screening in Germany. Further studies and efforts are highly needed to further explore and overcome the increased breast cancer mortality among elderly women in Germany.

Age-specific sequence of colorectal cancer screening options in Germany: A model-based critical evaluation

BACKGROUND

The current organized screening program for colorectal cancer in Germany offers both sexes 5 annual fecal immunochemical tests (FITs) between ages 50 and 54 years, followed by a first screening colonoscopy at age 55 years if all of these FITs were negative. We sought to assess the implications of this approach for key parameters of diagnostic performance.

METHODS AND FINDINGS

Using a multistate Markov model, we estimated the expected detection rates of advanced neoplasms (advanced adenomas and cancers) and number needed to scope (NNS) to detect 1 advanced neoplasm at a first screening colonoscopy conducted at age 55 after 5 preceding negative FITs and compared them with the corresponding estimates for a first screening colonoscopy at age 55 with no preceding FIT testing. In individuals with 5 consecutive negative FITs undergoing screening colonoscopy at age 55, expected colonoscopy detection rate (NNS) was 3.7% (27) and 0.10% (1,021) for any advanced neoplasm and cancer, respectively, in men, and 2.1% (47) and 0.05% (1,880) for any advanced neoplasm and cancer, respectively, in women. These NNS values for detecting 1 advanced neoplasm are approximately 3-fold higher, and the NNS values for detecting 1 cancer are approximately 8-fold higher, than those for a first screening colonoscopy at age 55 without prior FITs. This study is limited by model simplifying assumptions and uncertainties related to input parameters.

CONCLUSIONS

Screening colonoscopy at age 55 after 5 consecutive negative FITs at ages 50-54, as currently offered in the German cancer early detection program, is expected to have very low positive predictive value. Our results may inform efforts to enhance the design of screening programs.

[Access to statutory skin cancer screening : Organizational and regional factors in Germany]

BACKGROUND

In 2008, statutory skin cancer screening (gesetzliches Hautkrebsscreening, gHKS), conducted by dermatologists or general practitioners, was introduced in Germany. The aim was earlier detection of cancer and therefore improved health care delivery. To assess the success of the gHKS and to increase utilization, the opinion of the population on access to the gHKS is of great relevance.

OBJECTIVES

The study examines administrative and regional factors of access to the gHKS in Germany.

MATERIALS AND METHODS

In this cross-sectional study, a nationwide survey was conducted among statutory health insured persons aged 18 and over. They were interviewed by telephone about the gHKS with focus on the access to the gHKS. Descriptive statistics and subgroup analysis based on sociodemographic variables and physician specialties were performed.

RESULTS

Overall, 1015 people were interviewed, of whom 359 (35.4%) had already utilized the gHKS. Most of them (38.3%) were informed about this service by their general practitioner. Most respondents (70%) preferred having the dermatologists conduct the screening and more participants consulted the dermatologist than the general practitioner for it (76% vs. 24%). At the dermatologist, the travel time to the gHKS was more often longer than 30 min (12% vs. 1%, p < 0.05) and the waiting times for appointments were more often longer than 2 weeks (67% vs. 18%, p < 0.05). Regional differences were identified for travel times and the choice of travel modalities.

CONCLUSIONS

The participants of the study preferred having a dermatologist conduct the gHKS. The dermatologist was also consulted more frequently by the gHKS participants. However, access in terms of travel and waiting times for the gHKS was longer at the dermatologist than at the general practitioner.
