Perceptions and beliefs of general practitioners on their role in the cancer screening programmes in the Netherlands: a mixed-methods study.

BACKGROUND: In the Netherlands, population-based cancer screening programmes (CSPs) are organized aiming at cervical, breast and colorectal cancer. For a CSP to be effective, high participation rates are essential; however, there is an alarming downward trend, including wide regional variation in screening uptake. General practitioner (GP) involvement can have a stimulating effect on screening participation. Current GP involvement is however, limited, varies between the programmes and has changed over time. Unexplored is what GPs think of their role(s) in the CSPs. The aim of this study was therefore to map the perceptions and beliefs of GPs regarding their current and future role in the Dutch CSPs. METHODS: A mixed-methods sequential explanatory study was conducted in the Leiden/The Hague area of the Netherlands, between the end of 2021 and 2022. A questionnaire was developed and distributed among 110 GPs. The aggregated results obtained from the questionnaires served as starting points for conducting semi-structured interviews, with purposefully selected GPs. With this sequential approach we aimed to further enhance the understanding of the questionnaire data, and delved into the topics that emerged from the questionnaire responses. RESULTS: In total, 46 GPs completed the online questionnaire (response rate 42%). Subsequent five semi-structured comprehensive interviews were conducted. GPs indicated that they frequently encounter the CSP in their daily practice and consider it important. They also emphasised it is important that GPs remain closely involved with the CSPs in the future. Nevertheless, GPs also repeatedly mentioned that they are not eager to take on more logistical/organizational tasks. They are however willing to empower CSPs in a positive manner. CONCLUSION: GPs were generally positive about the CSPs and their current role within these programmes. Nevertheless, several options have been proposed to improve the CSPs, especially to increase screening uptake for populations in a socioeconomically disadvantaged position. Since it is of utmost importance to screen those who are most at risk of developing the screening-specific tumours, efforts should be made to achieve this goal.

Perspectives on cancer screening participation in a highly urbanized region: a Q-methodology study in The Hague, the Netherlands.

BACKGROUND: The Netherlands hosts, as many other European countries, three population-based cancer screening programmes (CSPs). The overall uptake among these CSPs is high, but has decreased over recent years. Especially in highly urbanized regions the uptake rates tend to fall below the minimal effective rate of 70% set by the World Health Organization. Understanding the reasons underlying the decision of citizens to partake in a CPS are essential in order to optimize the current screening participation rates. The aim of this study was to explore the various perspectives concerning cancer screening among inhabitants of The Hague, a highly urbanized region of the Netherlands. METHODS: A Q-methodology study was conducted to provide insight in the prevailing perspectives on partaking in CSPs. All respondents were inhabitants of the city of The Hague, the Netherlands. In an online application they ranked a set of 31 statements, based on the current available literature and clustered by the Integrated Change model, into a 9-column forced ranking grid according to level of agreement, followed by a short survey. Respondents were asked to participate in a subsequent interview to explain their ranking. By-person factor analysis was used to identify distinct perspectives, which were interpreted using data from the rankings and interviews. RESULTS: Three distinct perspectives were identified: 1). "Positive about participation", 2). "Thoughtful about participation", and 3). "Fear drives participation". These perspectives provide insight into how potential respondents, living in an urbanized region in the Netherlands, decide upon partaking in CSPs. CONCLUSIONS: Since CSPs will only be effective when participation rates are sufficiently high, it is essential to have insight into the different perspectives among potential respondents concerning partaking in a CSP. This study adds new insights concerning these perspectives and suggests several ideas for future optimization of the CSPs.

Stop smoking advice by practice assistants after routine cervical screening in general practice: A qualitative exploration of potential barriers and enablers.

BACKGROUND: Cervical screening could be an appropriate routine moment to provide female smokers with tailored stop smoking advice. In Dutch general practice, cervical smears are performed by practice assistants. OBJECTIVES: This study was performed in preparation for a randomised trial to identify potential barriers and enablers for a brief stop smoking strategy performed by trained practice assistants after routine cervical screening. METHODS: Between December 2016 and March 2017 three focus group meetings were held with ten practice assistants, three nurses, and six general practitioners to explore their views and expectations towards the proposed approach. We analysed data using thematic analysis. Identified factors are presented within the framework of the Social-Ecological Model. RESULTS: Potential barriers and enablers were identified at individual, interpersonal, and workplace levels. Practice assistants, nurses and GPs did not consider assistants to have a role in stop smoking care. They believed it is feasible to register smoking status but had reservations towards providing advice by assistants, for which knowledge and skills are needed. Practice assistants' own beliefs about smokers and smokers' response to stop smoking advice might influence how assistants and smokers interact. An explanation of why advice is given could help, provided assistants have enough time and experience with the smear. The nurses' availability and general practitioners' view on prevention might affect the delivery of the strategy by the assistant. CONCLUSION: At individual, interpersonal, and workplace levels, several factors could influence the provision of a stop smoking strategy by a practice assistant.

Mapping low-resource contexts to prepare for lung health interventions in four countries (FRESH AIR): a mixed-method study.

BACKGROUND: Effectiveness of health programmes can be undermined when the implementation misaligns with local beliefs and behaviours. To design context-driven implementation strategies, we explored beliefs and behaviours regarding chronic respiratory disease (CRD) in diverse low-resource settings. METHODS: This observational mixed-method study was conducted in Africa (Uganda), Asia (Kyrgyzstan and Vietnam) and Europe (rural Greece and a Roma camp). We systematically mapped beliefs and behaviours using the SETTING-tool. Multiple qualitative methods among purposively selected community members, health-care professionals, and key informants were triangulated with a quantitative survey among a representative group of community members and health-care professionals. We used thematic analysis and descriptive statistics. FINDINGS: We included qualitative data from 340 informants (77 interviews, 45 focus group discussions, 83 observations of community members' households and health-care professionals' consultations) and quantitative data from 1037 community members and 204 health-care professionals. We identified three key themes across the settings; namely, (1) perceived CRD identity (community members in all settings except the rural Greek strongly attributed long-lasting respiratory symptoms to infection, predominantly tuberculosis); (2) beliefs about causes (682 [65·8%] of 1037 community members strongly agreed that tobacco smoking causes symptoms, this number was 198 [19·1%] for household air pollution; typical perceived causes ranged from witchcraft [Uganda] to a hot-cold disbalance [Vietnam]); and (3) norms and social structures (eg, real men smoke [Kyrgyzstan and Vietnam]). INTERPRETATION: When designing context-driven implementation strategies for CRD-related interventions across these global settings, three consistent themes should be addressed, each with common and context-specific beliefs and behaviours. Context-driven strategies can reduce the risk of implementation failure, thereby optimising resource use to benefit health outcomes. FUNDING: European Commission Horizon 2020.

Age and educational inequalities in smoking cessation due to three population-level tobacco control interventions: findings from the International Tobacco Control (ITC) Netherlands Survey.

This study aimed to examine age and educational inequalities in smoking cessation due to the implementation of a tobacco tax increase, smoke-free legislation and a cessation campaign. Longitudinal data from 962 smokers aged 15 years and older were used from three survey waves of the International Tobacco Control (ITC) Netherlands Survey. The 2008 survey was performed before the implementation of the interventions and the 2009 and 2010 surveys were performed after the implementation. No significant age and educational differences in successful smoking cessation were found after the implementation of the three tobacco control interventions, although smokers aged 15-39 years were more likely to attempt to quit. Of the three population-level tobacco control interventions that were implemented simultaneously in the Netherlands, only the smoke-free legislation seemed to have increased quit attempts. The price increase of cigarettes may have been only effective in stimulating smoking cessation among younger smokers. Larger tax increases, stronger smoke-free legislation and media campaigns about the dangers of (second-hand) smoking are needed in the Netherlands.

Does smoke-free legislation and smoking outside bars increase feelings of stigmatization among smokers? Findings from the International Tobacco Control (ITC) Netherlands Survey.

This study examined whether smokers' perceived level of stigmatization changed after the implementation of smoke-free hospitality industry legislation and whether smokers who smoked outside bars reported more perceived stigmatization. Longitudinal data from the International Tobacco Control (ITC) Netherlands Survey was used, involving a nationally representative sample of 1447 smokers aged 15 years and older. Whether smoke-free legislation increases smokers' perceived stigmatization depends on how smokers feel about smoking outside. The level of perceived stigmatization did not change after the implementation of smoke-free hospitality industry legislation in the Netherlands, possibly because most Dutch smokers do not feel negatively judged when smoking outside.

[Passive smoking in young children in the Netherlands sharply decreased since 1996]. / Meeroken door kinderen in Nederland sinds 1996 sterk gedaald.

OBJECTIVE: To describe the prevalence of passive smoking in young children and to analyse the trends in the prevalence of passive smoking in young children over time. DESIGN: Retrospective, descriptive. METHOD: Data were derived from yearly samples of 500 to 800 adults living with children aged 0-4 years, who had completed a questionnaire on passive smoking and on several background characteristics. Data from 1996-2009 were analysed for trends in the prevalence of passive smoking and the relationship with characteristics such as smoking habits and socioeconomic status (SES). RESULTS: The percentage of families with young children (0-4 years) reporting smoking at home decreased sharply, from 64 in 1996 to 19 in 2009. Passive smoking sharply decreased as well. The prevalence of smoking at home in the presence of children was 10% in 2009 versus 48% in 1996. After the implementation of the smoking ban in hotels, restaurants and pubs in 2008 a sharper decrease in passive smoking at home was found than in the preceding years, except for the families with a lower SES. Passive smoking still occurs in 14% of families with children aged 2-4, in 29% of the families with a lower SES and in 22% of the families with smokers. Nearly 40% of the heavy smokers still expose their child to tobacco smoke at home. CONCLUSION: There is a distinct decrease in passive smoking at home in young children. In spite of this, there still are some groups of children that are regularly exposed to tobacco smoke. Preventive programs should be optimized to continue the decrease in passive smoking in these groups.

Gender differences in the association between pre-adolescent smoking initiation and emotional or behavioural problems.

BACKGROUND: Emotional and behavioural problems are a risk factor for the initiation of smoking. In this study, we aimed to assess this relationship beyond clinical cut-off values of problem behaviour. METHODS: Cross-sectional national survey among 9-13 year old children with data on smoking and Childhood Behaviour Checklist (CBCL) (N = 960). Relationships between smoking and tertiles of CBCL-scores were assessed. RESULTS: Smoking was reported by 5.9% of the children (7.1% boys and 5.0% girls, P > 0.100). Relationships between smoking and problem behaviour were present in girls, but ot in boys. Among girls, smoking was associated with attention problems, thought problems, and delinquent behaviour. For attention problems and delinquent behaviour the associations were limited to the CBCL-scores in the uppermost 16% which agrees with the subclinical cut-off value. CONCLUSION: Pre-adolescent girls more frequently smoke if having attention problems, delinquent behaviour, or thought problems.

Comparing three short questionnaires to detect psychosocial dysfunction among primary school children: a randomized method.

BACKGROUND: Good questionnaires are essential to support the early identification of children with psychosocial dysfunction in community based settings. Our aim was to assess which of three short questionnaires was most suitable for this identification among school-aged children METHODS: A community-based sample of 2,066 parents of children aged 7-12 years (85% of those eligible) filled out the Child Behavior Checklist (CBCL) and - randomly determined - one of three questionnaires to be compared: the Strengths and Difficulties Questionnaire with Impact Supplement (SDQ), the Pediatric Symptom Checklist (PSC) and the PSYBOBA, a Dutch-origin questionnaire. Preventive Child Healthcare professionals assessed children's psychosocial functioning during routine health examinations. We assessed the scale structure (by means of Structural Equation Modelling), validity (correlation coefficients, sensitivity and specificity) and usability (ratings by parents and professionals) of each questionnaire and the degree to which they could improve the identification based only on clinical assessment (logistic regression). RESULTS: For the three questionnaires, Cronbach's alphas varied between 0.80 and 0.89. Sensitivities for a clinical CBCL at a cut off point with specificity = 0.90 varied between 0.78 and 0.86 for the three questionnaires. Areas under the Receiver Operating Curve, using the CBCL as criterion, varied between 0.93 and 0.96. No differences were statistically significant. All three questionnaires added information to the clinical assessment. Odds ratios (95% confidence intervals) for added information were PSC: 29.3 (14.4-59.8), SDQ: 55.0 (23.1-131.2) and PSYBOBA: 68.5 (28.3-165.6). Parents preferred the SDQ and PSYBOBA. Preventive Child Health Care professionals preferred the SDQ. CONCLUSIONS: This randomized comparison of three questionnaires shows that each of the three questionnaires can improve the detection of psychosocial dysfunction among children substantially.

Clustering of socioeconomic, behavioural, and neonatal risk factors for infant health in pregnant smokers.

BACKGROUND: Tobacco smoking is a major cause of morbidity and mortality, including during pregnancy. Although effective ways of promoting smoking cessation during pregnancy exist, the impact of these interventions has not been studied at a national level. We estimated the prevalence of smoking throughout pregnancy in the Netherlands and quantified associations of maternal smoking throughout pregnancy with socioeconomic, behavioural, and neonatal risk factors for infant health and development. METHODOLOGY/PRINCIPAL FINDINGS: Data of five national surveys, containing records of 14,553 Dutch mothers and their offspring were analyzed. From 2001 to 2007, the overall rate of smoking throughout pregnancy fell by 42% (from 13.2% to 7.6%) mainly as a result of a decrease among highly educated women. In the lowest-educated group, the overall rate of smoking throughout pregnancy was six times as high as in the highest-educated group (18.7% versus 3.2%). Prenatal tobacco smoke exposure was associated with increased risk of extremely preterm (

Use of the Pediatric Symptom Checklist for the detection of psychosocial problems in preventive child healthcare.

BACKGROUND: Early detection and treatment of psychosocial problems by preventive child healthcare may lead to considerable health benefits, and a short questionnaire could support this aim. The aim of this study was to assess whether the Dutch version of the US Pediatric Symptom checklist (PSC) is valid and suitable for the early detection of psychosocial problems among children. METHODS: We included 687 children (response 84.3%) aged 7-12 undergoing routine health assessments in nine Preventive Child Health Services across the Netherlands. Child health professionals interviewed and examined children and parents. Before the interview, parents completed an authorised Dutch translation of the PSC and the Child Behavior Checklist (CBCL). The CBCL and data on the child's current treatment status were used as criteria for the validity of the PSC. RESULTS: The consistency of the Dutch PSC was good (Cronbach alpha 0.89). The area under the ROC curve using the CBCL as a criterion was 0.94 (95% confidence interval 0.92 to 0.96). At the US cut-off (28 and above), the prevalence rate of an increased score and sensitivity were lower than in the USA. At a lower cut-off (22 and above), sensitivity and specificity were similar to that of the US version (71.7% and 93.0% respectively). Information on the PSC also helped in the identification of children with elevated CBCL Total Problems Scores, above solely clinical judgment. CONCLUSION: The PSC is also useful for the early detection of psychosocial problems in preventive child healthcare outside the USA, especially with an adjusted cut-off.
