Factors triggering medical consultation for symptoms of colorectal cancer and perceptions surrounding diagnosis

Factors influencing symptom appraisal and help-seeking of older adults with possible cancer: a mixed-methods systematic review

BACKGROUND

The cancer burden falls predominantly on older (≥65 years) adults. Prompt presentation to primary care with cancer symptoms could result in earlier diagnosis. However, patient symptom appraisal and help-seeking decisions involving cancer symptoms are complex and may be further complicated in older adults.

AIM

To explore the effect of older age on patients' appraisal of possible cancer symptoms and their decision to seek help for these symptoms.

DESIGN AND SETTING

Mixed-methods systematic review.

METHOD

MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Library, Web of Science Core Collection, ASSIA, the ISRCTN registry, and the National Institute for Health and Care Excellence were searched for studies on symptom appraisal and help-seeking decisions for cancer symptoms by adults aged ≥65 years. Studies were analysed using thematic synthesis and according to the Synthesis Without Meta-Analysis guidelines.

RESULTS

Eighty studies were included with a total of 32 995 participants. Studies suggested a possible association between increasing age and prolonged symptom appraisal interval. Reduced knowledge of cancer symptoms and differences in symptom interpretation may contribute to this prolonged interval. In contrast, in the current study a possible association was found between increasing age and prompt help-seeking. Themes affecting help-seeking in older adults included the influence of family and carers, competing priorities, fear, embarrassment, fatalism, comorbidities, a desire to avoid doctors, a perceived need to not waste doctors' time, and patient self-management of symptoms.

CONCLUSION

This review suggests that increasing age is associated with delayed cancer symptom appraisal. When symptoms are recognised as potentially serious, increasing age was associated with prompt help-seeking although other factors could prolong this. Policymakers, charities, and GPs should aim to ensure older adults are able to recognise potential symptoms of cancer and seek help promptly.

Help-seeking behaviour for cancer symptoms: an evolutionary concept analysis

BACKGROUND

Cancer survival largely depends on its early diagnosis. Therefore, assessing help-seeking behaviours among people with potential symptoms of cancer is essential.

AIM

This study aimed to analyse the concept of help-seeking behaviour for cancer symptoms.

METHODS

This concept analysis was conducted using Rodger's evolutionary method. An online literature search was conducted in the PubMed, Scopus and Cochrane databases to find relevant articles published from 2000 to 2017 in English peer-reviewed journals. In total, ninety articles were included in the study. Through thematic analysis, the data were analysed for the definitions, attributes, antecedents and consequences of the concept of help-seeking behaviour for cancer symptoms.

RESULTS

The concept of help-seeking behaviour for cancer symptoms includes a chain of behaviours and is defined as the process of informed decision-making for seeking medical help and using healthcare services after the detection of the first potential cancer symptoms. The attributes of the concept of help-seeking behaviour for cancer symptoms include process, problem-centeredness, intentional action and interpersonal interaction. Antecedents of the concept of help-seeking behaviour for cancer symptoms were broadly categorised as its facilitators and barriers, among which old age, young age, marriage, low education level, positive family history of cancer, fear over cancer, low perceived threat, symptom disclosure to significant others are both facilitator and barrier. The consequences of the concept of help-seeking behaviour for cancer symptoms were also broadly categorised in the two main categories of positive consequences and adverse consequences.

CONCLUSIONS

Help-seeking behaviour is a multidimensional time-dependent and context-bound concept which is usually defined based on the concept of time in order to facilitate its measurement. It is generally used for assessing patients' delay in seeking medical help. The findings of this study provide better understanding about the concept of help-seeking behaviour for cancer symptoms and its implications for research and practice.

A review of sex-related differences in colorectal cancer incidence, screening uptake, routes to diagnosis, cancer stage and survival in the UK

Background

Colorectal cancer (CRC) is an illness strongly influenced by sex and gender, with mortality rates in males significantly higher than females. There is still a dearth of understanding on where sex differences exist along the pathway from presentation to survival. The aim of this review is to identify where actions are needed to improve outcomes for both sexes, and to narrow the gap for CRC.

Methods

A cross-sectional review of national data was undertaken to identify sex differences in incidence, screening uptake, route to diagnosis, cancer stage at diagnosis and survival, and their influence in the sex differences in mortality.

Results

Overall incidence is higher in men, with an earlier age distribution, however, important sex differences exist in anatomical site. There were relatively small differences in screening uptake, route to diagnosis, cancer staging at diagnosis and survival. Screening uptake is higher in women under 69 years. Women are more likely to present as emergency cases, with more men diagnosed through screening and two-week-wait. No sex differences are seen in diagnosis for more advanced disease. Overall, age-standardised 5-year survival is similar between the sexes.

Conclusions

As there are minimal sex differences in the data from routes to diagnosis to survival, the higher mortality of colorectal cancer in men appears to be a result of exogenous and/or endogenous factors pre-diagnosis that lead to higher incidence rates. There are however, sex and gender differences that suggest more targeted interventions may facilitate prevention and earlier diagnosis in both men and women.

A model for assessment and referral of clients with bowel symptoms in community pharmacies

BACKGROUND

To expedite diagnosis of serious bowel disease, efforts are required to signpost patients with high-risk symptoms to appropriate care. Community pharmacies are a recognized source of health advice regarding bowel symptoms. This study aimed to examine the effectiveness of a validated self-administered questionnaire, Jodi Lee Test (JLT), for detection, triage, and referral of bowel symptoms suggestive of carcinoma, in pharmacies.

METHOD

'Usual Practice' was monitored for 12 weeks in 21 pharmacies in Western Australia, documenting outcomes for 84 clients presenting with bowel symptoms. Outcome measures were: acceptance of verbal advice from the pharmacist; general practitioner consultation; and diagnosis. Trial of the JLT involved staff training in the research protocol and monitoring of outcomes for 80 recruited clients over 20 weeks. Utility of the JLT was assessed by post-trial survey of pharmacy staff.

RESULTS

Significantly more referrals were made by staff using the JLT than during Usual Practice: 30 (38%) vs 17 (20%). Clients' acceptance of referrals was also higher for the intervention group (40% vs 6%). Two-thirds of pharmacy staff agreed that the JLT could be incorporated into pharmacy practice, and 70% indicated they would use the JLT in the future.

CONCLUSION

A pre-post design was considered more appropriate than a randomized control trial due to an inability to match pharmacies. Limitations of this study were: lack of control over adherence to the study protocol by pharmacy staff; no direct measure of client feedback on the JLT; and loss to follow-up. The JLT was effective in prompting decision-making by pharmacy staff and inter-professional care between pharmacies and general practice, in triage of clients at risk of bowel cancer.

Symptom appraisal and healthcare-seeking for symptoms suggestive of colorectal cancer: a qualitative study

OBJECTIVES

Timely diagnosis of colorectal cancer is important to improve survival. This study explored symptom appraisal and help-seeking among patients referred to specialist services with symptoms of colorectal cancer.

DESIGN

Qualitative in-depth interview study.

SETTING AND PARTICIPANTS

Participants were recruited on referral to gastroenterology clinics (North East and East of England); interviews were conducted soon after referral. We purposively sampled participants to ensure a range of accounts in terms of age, sex, diagnosis and geographical location.

METHODS

Data collection and analysis were underpinned by the Model of Pathways to Treatment. Framework analysis was used to explore the data within and across cases, focusing on patient beliefs and experiences, disease factors and healthcare influences.

RESULTS

40 participants were interviewed (aged 43-87 years, 17 women, 18 diagnosed with colorectal cancer). Patients diagnosed with and without colorectal cancer had similar symptom pathways. We found a range of interacting and often competing biopsychosocial, contextual and cultural influences on the way in which people recognised, interpreted and acted on their symptoms. People attempted to 'maintain normality' through finding benign explanations for their symptoms. Bodily changes were appraised within the context of usual bowel patterns, comorbidities and life events, and decisions to seek help were made in relation to expectations about the course of symptoms. The 'private nature' of colorectal cancer symptoms could affect both their identification and discussions with others including healthcare professionals. Within the context of the National Health Service, people needed to legitimise appropriate use of healthcare services and avoid being thought of as wasting doctors' time.

CONCLUSIONS

Findings provide guidance for awareness campaigns on reducing stigma around appraising and discussing bowel movements, and the importance of intermittent and non-specific symptoms. Altering perceptions about the appropriate use of health services could have a beneficial effect on time to presentation.

Psychosocial factors that influence men's help-seeking for cancer symptoms: a systematic synthesis of mixed methods research

OBJECTIVE

Effectiveness of cancer control partly depends upon early identification and treatment. Men appear to be more likely to delay help-seeking for symptoms, resulting in later diagnosis. This review aims to provide a mixed research synthesis of the psychosocial barriers to and facilitators of help-seeking for cancer symptoms among men.

METHODS

Systematic methods were followed, including a predefined research question and search strategy. Searches retrieved 7131 international records from online databases: MEDLINE (n = 3011), PubMed (n = 471), SCOPUS (n = 896), Informit (n = 131), PsychINFO (n = 347), and Web of Science (n = 2275). Forty studies were eligible for inclusion in the review (25 qualitative studies, 11 quantitative studies, and 4 mixed-method studies).

RESULTS

There was strong observational evidence for several psychosocial barriers to men's help-seeking behaviour: low cancer knowledge and inaccurate symptom interpretation, embarrassment and fear, and conformity to masculine gender role norms. The strongest facilitating factor associated with men's help-seeking behaviour was encouragement and support of spouses and family members. The majority of research was qualitative and used small samples, making generalisations to the wider population difficult.

CONCLUSIONS

Men's help-seeking for cancer symptoms is influenced by several psychosocial factors, which, in part, may be gender-specific. Health promotion initiatives to improve help-seeking behaviour among men should aim to increase cancer knowledge, reduce embarrassment and fear, address social norms deterring timely help-seeking, and acknowledge informal help-seeking with spouses and family members. Increasing the theoretical grounding of research could aid cohesion across the research area and the design of effective health promotion interventions. Copyright © 2015 John Wiley & Sons, Ltd.

Help-seeking experiences of men diagnosed with colorectal cancer: a qualitative study

Advanced-stage diagnosis of colorectal cancer (CRC) leads to poor prognosis and reduced survival rates. The current study seeks to explore the reasons for diagnostic delays in a sample of Australian men with CRC. Semi-structured interviews were conducted in a purposive sample of 20 male CRC patients. Data collection ceased when no new data emerged. Interviews were audiotaped, transcribed and thematically analysed using Andersen's Model of Total Patient Delay as the theoretical framework. Most participants (18/20) had experienced lower bowel symptoms prior to diagnosis. Patient-related delays were more common than delays attributable to the health-care system. Data regarding patient delays fit within the first four stages of Andersen's model. The barriers to seeking timely medical advice were mainly attributed to misinterpretation of symptoms, fear of cancer diagnosis, reticence to discuss the symptoms or consulting a general practitioner. Treatment delays were a minor cause for delayed diagnosis. Delay in referral and scheduling for colonoscopy were among the system-delay factors. In many instances, delays resulted from men's failure to attribute their symptoms to cancer and, subsequently, delay in diagnosis.

The Danish Symptom Cohort: Questionnaire and Feasibility in the Nationwide Study on Symptom Experience and Healthcare-Seeking among 100 000 Individuals

Introduction. In order to develop strategies to prevent delay in diagnosis, it is important to gain knowledge of symptoms and healthcare-seeking processes in the population. This paper describes a combined survey and register-based study with (1) focus on development of a questionnaire concerning experience of symptoms and subsequent consequences and (2) feasibility of the study. Methods. The study is a nationwide cohort study of 100 000 individuals randomly selected from the Danish general population. A comprehensive questionnaire concerning experience of symptoms and subsequent consequences was developed. The methodological framework for the development included defining the domains to be measured, identification of previous items, scales and questionnaires in the literature, and pilot and field testing. Results. A total of five domains and 16 subdomains were defined covering the area of symptom experience, symptom characteristics, reaction in response to symptom experience, external factors, and personality characteristics with potential influence on the symptom experience. In total, 49 706 questionnaires were completed, yielding a response rate of 52.2%. Conclusion. We developed a comprehensive questionnaire used in a large combined survey and register-based study concerning experience of symptoms and subsequent consequences of symptom experiences. We succeeded in conducting a large survey providing the groundwork for The Danish Symptom Cohort.

Patients' experiences of an initial consultation in oncology: knowing and not knowing

OBJECTIVES

The aim of this paper was to explore how patients experience an initial oncology consultation. This study was part of a larger mixed methods research project designed to address the issue of improving communication and enhancing patient satisfaction with oncology consultations.

DESIGN

Interpretive phenomenological analysis was used to interpret the participants' meanings of their experiences in their initial consultation. It is an idiographic approach that focuses in depth on a small set of cases in order to explore how individuals make sense of a similar experience. This retains the complexity and diversity of experiences.

METHODS

In the larger study, semi-structured interviews were carried out with 36 patients as soon as possible after a consultation in oncology to explore their experiences. Five cases were selected for this study on the basis of homogeneity; they had all undergone some prior investigations of their illness, and this was their first consultation in oncology; they all provided rich accounts relating to how they had experienced the consultation.

RESULTS

Patients' experiences of being given their diagnosis differed both between participants and within the same participant. Various defences seemed to be used in order to protect them from fully engaging with the knowledge they were given. Their accounts of what they wished to know in the consultation could be affected by a desire to protect themselves and/or family members from distress and by the practical need to know that may vary over time.

CONCLUSION

The complexity of patients' needs and preferences regarding information means that the doctor's role in communicating that information in a patient-centred way is difficult. The findings are discussed in relation to open awareness theory as to how the emotional context of the consultation process affects information needs. Doctors need strategies to elicit information from patients about their needs from the consultation. This needs to be done at the start of consultations and throughout investigations and treatment, as needs may change over time. Statement of contribution What is already known on this subject? Patients' desire to know information is sometimes tempered with by a desire to avoid distress to themselves. Patients do not always understand or make accurate sense of what they have been told. Receiving a diagnosis of cancer is distressing for patients. What does this study add? Doctors need strategies to elicit information from patients about their needs for each consultation. This needs to be done consistently throughout the patient journey as needs may change over time. Patients control what they do or do not do with information but do not openly share this with the doctor. Our interpretations of the interviews stray beyond the conscious accounts of the consultations and draw on (unconscious) absences that may also be of significance in making sense of overall experience. The complexity of patients' needs and preferences regarding information means that the doctors' role is very difficult. Patients have a right to know but not a duty to know their diagnosis and prognosis.

Factors related with symptom duration until diagnosis and treatment of symptomatic colorectal cancer

Background

Colorectal cancer (CRC) survival depends mostly on stage at the time of diagnosis. However, symptom duration at diagnosis or treatment have also been considered as predictors of stage and survival. This study was designed to: 1) establish the distinct time-symptom duration intervals; 2) identify factors associated with symptom duration until diagnosis and treatment.

Methods

This is a cross-sectional study of all incident cases of symptomatic CRC during 2006–2009 (795 incident cases) in 5 Spanish regions. Data were obtained from patients’ interviews and reviews of primary care and hospital clinical records. Measurements: CRC symptoms, symptom perception, trust in the general practitioner (GP), primary care and hospital examinations/visits before diagnosis, type of referral and tumor characteristics at diagnosis. Symptom Diagnosis Interval (SDI) was calculated as time from first CRC symptoms to date of diagnosis. Symptom Treatment Interval (STI) was defined as time from first CRC symptoms until start of treatment. Nonparametric tests were used to compare SDI and STI according to different variables.

Results

Symptom to diagnosis interval for CRC was 128 days and symptom treatment interval was 155. No statistically significant differences were observed between colon and rectum cancers. Women experienced longer intervals than men. Symptom presentation such as vomiting or abdominal pain and the presence of obstruction led to shorter diagnostic or treatment intervals. Time elapsed was also shorter in those patients that perceived their first symptom/s as serious, disclosed it to their acquaintances, contacted emergencies services or had trust in their GPs. Primary care and hospital doctor examinations and investigations appeared to be related to time elapsed to diagnosis or treatment.

Conclusions

Results show that gender, symptom perception and help-seeking behaviour are the main patient factors related to interval duration. Health service performance also has a very important role in symptom to diagnosis and treatment interval. If time to diagnosis is to be reduced, interventions and guidelines must be developed to ensure appropriate examination and diagnosis during both primary and hospital care.

[Attitudes of primary health care users to a colorectal cancer screening program]

OBJECTIVE

To describe the cultural, social and gender features that determine attitudes to colorectal cancer screening in a target group of patients aged 50 to 69 years old in the primary health care setting.

METHODS

We performed a qualitative ethnographic study from a gender perspective. Participants consisted of men and women aged 50 to 69 years old in the Balearic Islands and Barcelona. Group discussion and a field diary were used.

RESULTS

The key element was diagnosis at an early stage. Until recently, cancer was considered an incurable disease but is currently perceived as a serious health problem that can be cured if diagnosed promptly. The participants requested more information on cancer and felt they were at risk, mainly because of their age. Men tended to pay attention to symptoms while women tended to ignore them. Attitudes to colorectal cancer screening were generally positive, even to colonoscopy. Some barriers to screening were identified in women, such as a fear of having cancer.

CONCLUSIONS

The opportunity for early diagnosis is the key element in promoting participation in a colorectal cancer screening program. Perceptions-and hence willingness to participate in screening-differ between men and women. Factors to be taken into account in the design of population-based colorectal cancer programs are health concerns in men and fear of a cancer diagnosis in women.

Patients who take their symptoms less seriously are more likely to have colorectal cancer

BACKGROUND

People vary in how they respond to symptoms. The purpose of this study was to assess whether serious disease is more likely to be present in patients who report that they take any symptoms less seriously than other people do, and to assess the reliability of a question which can be used to identify the extent to which patients take any symptom seriously. To do this we assessed whether the likelihood of detecting colorectal cancer is higher in patients who report that they take symptoms less seriously than other people do.

METHODS

Cross sectional study of 7736 patients who had colonoscopy to find colorectal cancer. Before colonoscopy, patients completed a questionnaire on bowel symptoms and were also asked: "Compared to other people of your age and sex, how seriously do you think you take any symptoms?" Likelihood of detecting colorectal cancer according to responses to this question was assessed by logistic regression models, unadjusted and adjusted for symptoms and other known predictors of colorectal cancer.Question reliability was assessed in a different sample using percentage agreement and the kappa statistic for the answers given by each patient on two occasions. Agreement between patient and doctor responses was also assessed (n = 108).

RESULTS

Patients who reported they took symptoms less seriously were 3.28 (95%CI: 2.02, 5.33) times more likely to have colorectal cancer than patients who took symptoms more seriously than others. The effect was smaller (1.85 (95%CI: 1.11, 3.09)), but remained statistically significant in models including symptoms and other predictors of colorectal cancer. The question was reliable: on repeat questioning, 70% of responses were in absolute agreement and 92% were within 1 category, kappa 57%. Patient-doctor agreement was 66%, within 1 category 92%, kappa 48%.

CONCLUSION

Patients who take their symptoms less seriously have a considerably higher likelihood of colorectal cancer than those who identify themselves as taking any symptoms more seriously than other people. The question is easy to ask and has good reliability. Doctors also reliably identify how patients assess themselves. Assessment of how seriously patients take any symptoms can contribute to the clinical assessment of a patient.

Factors associated with consultation behaviour for primary symptoms potentially indicating colorectal cancer: a cross-sectional study on response to symptoms

Background

Little data exists on the factors associated with health care seeking behaviour for primary symptoms of colorectal cancer (CRC). This study aimed to identify individual, provider and psychosocial factors associated with (i) ever seeking medical advice and (ii) seeking early medical advice for primary symptoms of colorectal cancer (CRC).

Methods

1592 persons aged 56–88 years randomly selected from the Hunter Community Study (HCS) were sent a questionnaire.

Results

Males and those who had received screening advice from a doctor were at significantly higher odds of ever seeking medical advice for rectal bleeding. Persons who had private health coverage, consulted a doctor because the ‘symptom was serious’, or who did not wait to consult a doctor for another reason were at significantly higher odds of seeking early medical advice (< 2 weeks). For change in bowel habit, persons with lower income, within the healthy weight range, or who had discussed their family history of CRC irrespective of whether informed of ‘increased risk’ were at significantly higher odds of ever seeking medical advice. Persons frequenting their GP less often and seeing their doctor because the symptom persisted were at significantly higher odds of seeking early medical advice (< 2 weeks).

Conclusions

The seriousness of symptoms, importance of early detection, and prompt consultation must be articulated in health messages to at-risk persons. This study identified modifiable factors, both individual and provider-related to consultation behaviour. Effective health promotion efforts must heed these factors and target sub-groups less likely to seek early medical advice.
