The psychological costs of screening for cancer

Individuals' Experiences of Being Screened for Hypertension in Dental Health Care - "No Big Deal"

BACKGROUND

Hypertension is a common disease globally that accounts for the highest number of lost healthy life years and strongly associated with sequelae such as stroke and myocardial infarction. Early detection of individuals with high blood pressure can be ensured by screening also those who consider themselves "healthy". Screening has both positive and negative effects where a diagnosis of hypertension can lead to worry about the future. These effects need to be elucidated in order to balance between benefit and harm before screening is introduced. The aim of the study was to describe individuals' experiences of being screened for hypertension in dental health care.

METHODS

Data from individual semi-structured interviews, with twenty participants screened for cardiovascular risk factors in connection with dental examination and aged 55-80 years, were analysed by means of qualitative content analysis.

RESULTS

The results describe individuals' experiences of blood pressure screening in dental health care by means of the following theme: "No big deal" based on two categories: "Convenient way of measuring blood pressure" and "Increased awareness of health".

CONCLUSION

The overall message from the interviews was that having one's blood pressure measured when visiting the dentist was convenient, easy and "No big deal". Blood pressure screening did not create any major concerns and contributed to an increased awareness of health.

Mapping the spectrum of psychological and behavioural responses to low-dose CT lung cancer screening offered within a Lung Health Check

BACKGROUND

Research on the psychological impact of low-dose computed tomography (LDCT) lung cancer screening has typically been narrow in scope and restricted to the trial setting.

OBJECTIVE

To explore the range of psychological and behavioural responses to LDCT screening offered as part of a Lung Heath Check (LHC), including lung cancer risk assessment, spirometry testing, a carbon monoxide reading and smoking cessation advice.

METHODS

Semi-structured interviews were carried out with 28 current and former smokers (aged 60-75), who had undergone LDCT screening as part of a LHC appointment and mostly received an incidental or indeterminate result (n = 23). Framework analysis was used to map the spectrum of responses participants had across the LHC appointment and screening pathway, to their LDCT results and to surveillance.

RESULTS

Interviewees reported a diverse range of both positive and negative psychological responses, beginning at invitation and spanning the entire LHC appointment (including spirometry) and LDCT screening pathway. Similarly, positive behavioural responses extended beyond smoking cessation to include anticipated implications for other cancer prevention and early detection behaviours, such as symptom presentation. Individual differences in responses appeared to be influenced by smoking status and LDCT result, as well as modifiable factors including perceived risk and health status, social support, competing priorities, fatalism and perceived stigma.

CONCLUSIONS

The diverse ways in which participants responded to screening, both psychologically and behaviourally, should direct a broader research agenda to ensure all stages of screening delivery and communication are designed to promote well-being, motivate positive behaviour change and maximize patient benefit.

Changes in diabetes distress among people with type 2 diabetes during a risk screening programme for diabetic kidney disease - Longitudinal observations of the PRIORITY study

AIMS

To investigate levels and changes in diabetes distress over the course of the PRIORITY (Proteomic prediction and Renin angiotensin aldosterone system Inhibition prevention Of early diabetic nephRopathy In people with TYpe 2 diabetes and normoalbuminuria) randomised controlled trial of screening for diabetic kidney disease (DKD) risk among people with type 2 diabetes (T2D) at a specialist diabetes clinic in Denmark.

METHODS

Of 436 trial participants with T2D, 216 were invited to complete the 17-item diabetes distress scale at the time of screening (T1, n = 180), immediately after receiving the screening results at 6-8 weeks (T2, n = 169), and at 12 months follow up (T3, n = 107). Linear mixed models were used to explore changes in diabetes distress.

RESULTS

No significant changes in diabetes distress were observed between the time of screening, receiving results, and at 12 months. Changes in diabetes distress were not influenced by diabetes empowerment, sense of coherence, or perceived support for diabetes self-management.

CONCLUSIONS

In contrast to previous studies demonstrating that screening programmes can have negative psychological consequences, our findings indicate that participating in this screening programme for DKD does not influence emotional burden or physician-related distress among people with T2D.

Low-dose computed tomography for lung cancer screening in high-risk populations: a systematic review and economic evaluation

BACKGROUND

Diagnosis of lung cancer frequently occurs in its later stages. Low-dose computed tomography (LDCT) could detect lung cancer early.

OBJECTIVES

To estimate the clinical effectiveness and cost-effectiveness of LDCT lung cancer screening in high-risk populations.

DATA SOURCES

Bibliographic sources included MEDLINE, EMBASE, Web of Science and The Cochrane Library.

METHODS

Clinical effectiveness - a systematic review of randomised controlled trials (RCTs) comparing LDCT screening programmes with usual care (no screening) or other imaging screening programmes [such as chest X-ray (CXR)] was conducted. Bibliographic sources included MEDLINE, EMBASE, Web of Science and The Cochrane Library. Meta-analyses, including network meta-analyses, were performed. Cost-effectiveness - an independent economic model employing discrete event simulation and using a natural history model calibrated to results from a large RCT was developed. There were 12 different population eligibility criteria and four intervention frequencies [(1) single screen, (2) triple screen, (3) annual screening and (4) biennial screening] and a no-screening control arm.

RESULTS

Clinical effectiveness - 12 RCTs were included, four of which currently contribute evidence on mortality. Meta-analysis of these demonstrated that LDCT, with ≤ 9.80 years of follow-up, was associated with a non-statistically significant decrease in lung cancer mortality (pooled relative risk 0.94, 95% confidence interval 0.74 to 1.19). The findings also showed that LDCT screening demonstrated a non-statistically significant increase in all-cause mortality. Given the considerable heterogeneity detected between studies for both outcomes, the results should be treated with caution. Network meta-analysis, including six RCTs, was performed to assess the relative clinical effectiveness of LDCT, CXR and usual care. The results showed that LDCT was ranked as the best screening strategy in terms of lung cancer mortality reduction. CXR had a 99.7% probability of being the worst intervention and usual care was ranked second. Cost-effectiveness - screening programmes are predicted to be more effective than no screening, reduce lung cancer mortality and result in more lung cancer diagnoses. Screening programmes also increase costs. Screening for lung cancer is unlikely to be cost-effective at a threshold of £20,000/quality-adjusted life-year (QALY), but may be cost-effective at a threshold of £30,000/QALY. The incremental cost-effectiveness ratio for a single screen in smokers aged 60-75 years with at least a 3% risk of lung cancer is £28,169 per QALY. Sensitivity and scenario analyses were conducted. Screening was only cost-effective at a threshold of £20,000/QALY in only a minority of analyses.

LIMITATIONS

Clinical effectiveness - the largest of the included RCTs compared LDCT with CXR screening rather than no screening. Cost-effectiveness - a representative cost to the NHS of lung cancer has not been recently estimated according to key variables such as stage at diagnosis. Certain costs associated with running a screening programme have not been included.

CONCLUSIONS

LDCT screening may be clinically effective in reducing lung cancer mortality, but there is considerable uncertainty. There is evidence that a single round of screening could be considered cost-effective at conventional thresholds, but there is significant uncertainty about the effect on costs and the magnitude of benefits.

FUTURE WORK

Clinical effectiveness and cost-effectiveness estimates should be updated with the anticipated results from several ongoing RCTs [particularly the NEderlands Leuvens Longkanker Screenings ONderzoek (NELSON) screening trial].

High test positivity and low positive predictive value for colorectal cancer of continued faecal occult blood test screening after negative colonoscopy

Objectives The English Bowel Cancer Screening Programme offers biennial guaiac faecal occult blood test (gFOBT) screening to 60-74-year-olds. Participants with positive results are referred for follow-up, but many do not have significant findings. If they remain age eligible, these individuals are reinvited for gFOBT screening. We evaluated the performance of repeat screening in this group. Methods We analysed data on programme participants reinvited to gFOBT screening after either previous negative gFOBT ( n = 327,542), or positive gFOBT followed by a diagnostic investigation negative for colorectal cancer (CRC) or adenomas requiring surveillance ( n = 42,280). Outcomes calculated were uptake, test positivity, yield of CRC, and positive predictive value (PPV) of gFOBT for CRC. Results For participants with a previous negative gFOBT, uptake in the subsequent screening round was 87.5%, positivity was 1.3%, yield of CRC was 0.112% of those adequately screened, and the PPV of gFOBT for CRC was 9.1%. After a positive gFOBT and a negative diagnostic investigation, uptake in the repeat screening round was 82.6%, positivity was 11.3%, CRC yield was 0.172% of participants adequately screened, and the PPV of gFOBT for CRC was 1.7%. Conclusion With high positivity and low PPV for CRC, the suitability of routine repeat gFOBT screening in two years among individuals with a previous positive test and a negative diagnostic examination needs to be carefully considered.

Demographic, clinical, dispositional, and social-environmental characteristics associated with psychological response to a false positive ovarian cancer screening test: a longitudinal study

Cancer screening can facilitate early detection that improves survival, but also can identify an abnormal finding that is not malignant and deemed benign. While such false positive (FP) results can impact a variety of psychological outcomes, little is known about demographic, clinical, dispositional, and social-environmental characteristics associated with psychological outcomes after a FP result. Women participating in an ovarian cancer (OC) screening program and experiencing a FP screening test result (n = 375) completed assessments at baseline and 4-months. Results indicated greater social constraint and less education were linked to greater OC-specific distress at both assessments. Short-term predictors included less optimism and no previous abnormal test, while longer-term predictors were fewer previous screens and the interaction between OC family history and monitoring coping style. Younger age, less education, less optimism, greater social constraint, and family history of OC were associated with greater perceptions of OC risk. Brief interventions prior to screening may minimize the negative impact of a false positive result and not interfere with compliant participation in screening programs.

Affective, cognitive and behavioral outcomes associated with a false positive ovarian cancer screening test result

While participation in cancer screening can facilitate early detection and improved prognosis, all screening tests yield some proportion of abnormal test results which are later determined benign. These false positive (FP) results can negatively impact affective, cognitive, and behavioral outcomes. Women participating in an ovarian cancer (OC) screening program receiving an abnormal screening test result (n = 375) were matched with women receiving normal results (n = 375). Both groups completed a baseline and 1- and 4-month follow-up assessments. FP test results were clearly associated with increased cancer-specific distress and increased perceptions of OC risk with more limited evidence for increased perceived positive consequences of screening and increased intentions to participate in future OC screening. FP OC screening test results negatively impact both affective and cognitive outcomes which may serve to reduce motivation to participate in future routine screening. The development and testing of brief, timely interventions to minimize this negative impact is warranted.

Psychological and Behavioral Impact of Participation in Ovarian Cancer Screening

Evaluation of costs and benefits associated with cancer screening should include consideration of any psychological and behavioral impact associated with screening participation. Research examining the psychological and behavioral impact of screening asymptomatic women for ovarian cancer (OC) was considered. Research has focused upon potential negative psychological (e.g., distress) and behavioral (e.g., reduced future screening participation) impact of false positive (FP) OC test results. Results suggest FP OC screening results are associated with greater short-term OC-specific distress. While distress dissipates over time it may remain elevated relative to pre-screening levels for several weeks or months even after clinical follow-up has ruled out malignancy. The likelihood of participation in future OC screening may also be reduced. Research focused upon identification of any beneficial impact of participation in OC screening associated with receipt of “normal” results was also considered. This research suggests that a “normal” screening test result can have psychological benefits, including increased positive affect and beliefs in the efficacy of screening. It is concluded that any psychological or behavioral harms attributable to OC screening are generally very modest in severity and duration and might be counterbalanced by psychological benefits accruing to women who participate in routine OC screening and receive normal test results.

A Longitudinal Study of Psychological Distress in Women with Breast Symptoms

The aim of the study was to measure psychological distress in women with breast symptoms over a period of three months following an outpatient appointment at a rapid access symptomatic breast clinic. Women were recruited (N = 150) at the weekly clinic and psychological distress was measured using the Hospital Anxiety and Depression Scale, the General Health Questionnaire-12 and the Spielberger State-Trait Anxiety Inventory. Information on age and diagnosis was collected from medical notes. Measures were repeated at two weeks and at three months. Participants were divided into three diagnostic categories: B 1 (benign diagnosis at clinic); B2 (benign after further investigations); and M (breast cancer). Overall, scores of anxiety and GHQ-12 decreased significantly during the follow- up period. However, participants in the B2 group remained significantly more distressed than the rest of the sample throughout the experimental period. Depression remained within the normal range throughout the follow-up period for all categories. The study suggests a relationship between symptomatic breast disease and psychological distress.

The prevalence of medical reasons for non-participation in the Scottish breast and bowel cancer screening programmes

Objective

Increasing uptake of cancer screening is a priority for health systems internationally, however, some patients may not attend because they are undergoing active treatment for the cancer of interest or have other medical reasons that mean participation would be inappropriate. This study aims to quantify the proportion of non-participants who have a medical reason for not attending cancer screening.

Methods

Medical reasons for not participating in breast and bowel screening were defined a priori on the basis of a literature review and expert opinion. The notes of 700 patients at two GP practices in Scotland were reviewed, to ascertain the prevalence of medical reasons amongst non-participants. Simple proportions and confidence intervals were calculated.

Results

17.4% of breast and 2.3% of bowel screening non-participants had a medical reason to not participate. The two most common reasons were previous breast cancer follow up (8.86%) and recent mammogram (6.57%).

Conclusion

These patients may not benefit from screening while also being distressed by receiving an invitation. This issue also makes accurate monitoring and target-setting for improving uptake difficult. Further work is needed to estimate robustly the extent to which medical reasons account for screening non-participation in a larger population.

Acceptability of screening to prevent osteoporotic fractures: a qualitative study with older women

BACKGROUND

Osteoporotic fractures have a detrimental impact on health and quality of life, are more common in older women and are costly to treat. Screening to identify older women at high risk of fracture has the potential to offer substantial benefits. Understanding women's and professionals' experiences of screening will inform the implementation of screening in routine care.

OBJECTIVE

To explore the views of older women and GPs about the acceptability of screening to prevent fractures.

METHODS

A qualitative study conducted within a multi-centre randomized controlled trial of the effectiveness and cost-effectiveness of screening women aged 70-85 years for the prevention of fractures; 30 women randomized to the trial screening group and 15 GPs were recruited from general practices in North Somerset and Norfolk, UK. All 30 women and 11 of the GPs participated in face-to-face semi-structured interviews. Four GPs participated in a focus group. Data were analysed thematically, using the Framework Approach.

RESULTS

Women and GPs viewed screening positively, recognizing its potential to improve fracture prevention and future health. Attending screening was not found to result in anxiety or excessive activity restriction. Demonstrating cost-effectiveness was key to the acceptability of screening amongst GPs. Implementing similar screening in routine care would require consideration of access to bone density scans, information provision to participants and mode of administration.

CONCLUSIONS

Our findings suggest an effective and cost-effective screening programme to reduce osteoporotic fractures could be implemented in routine care and would be well received by women and GPs.

Use of electronic health record data to evaluate overuse of cervical cancer screening

BACKGROUND

National organizations historically focused on increasing use of effective services are now attempting to identify and discourage use of low-value services. Electronic health records (EHRs) could be used to measure use of low-value services, but few studies have examined this. The aim of the study was to: (1) determine if EHR data can be used to identify women eligible for an extended Pap testing interval; (2) determine the proportion of these women who received a Pap test sooner than recommended; and (3) assess the consequences of these low-value Pap tests.

METHODS

Electronic query of EHR data identified women aged 30-65 years old who were at low-risk of cervical cancer and therefore eligible for an extended Pap testing interval of 3 years (as per professional society guidelines). Manual chart review assessed query accuracy. The use of low-value Pap tests (ie, those performed sooner than recommended) was measured, and adverse consequences of low-value Pap tests (ie, colposcopies performed as a result of low-value Pap tests) were identified.

RESULTS

Manual chart review confirmed query accuracy. Two-thirds (1120/1705) of low-risk women received a Pap test sooner than recommended, and 21 colposcopies were performed as a result of this low-value Pap testing.

CONCLUSION

Secondary analysis of EHR data can accurately measure the use of low-value services such as Pap testing performed sooner than recommended in women at low risk of cervical cancer. Similar application of our methodology could facilitate efforts to simultaneously improve quality and decrease costs, maximizing value in the US healthcare system.

Human papillomavirus testing in primary cervical screening and the cut-off level for hybrid capture 2 tests: systematic review

OBJECTIVE

To determine the trade-off between the sensitivity and the specificity for high grade cervical intraepithelial neoplasia at hybrid capture 2 cut-off values above the standard ≥ 1 relative light units/cut-off level (rlu/co).

DESIGN

Systematic review.

DATA SOURCES

PubMed.

STUDY SELECTION

Randomised controlled trials in primary cervical screening using hybrid capture 2 testing in the intervention arms. Articles published until August 2010 were included if the numbers of women with positive test results and with cervical intraepithelial neoplasia were stratified by hybrid capture 2 cut-off levels.

PARTICIPANTS

Women in the baseline screening rounds of the trials.

INTERVENTIONS

Hybrid capture 2 screening in the baseline round including the diagnostic follow-up as practised in the randomised controlled trials and as reported by hybrid capture 2 cut-off values.

RESULTS

Owing to heterogeneity in the trials, meta-analysis was not possible. Including cut-off values up to ≥ 10 rlu/co, 25 observation points were available for analysis. The relative sensitivity for cervical intraepithelial neoplasia grade III or higher at cut-off levels of ≥ 2, ≥ 4 or ≥ 5, and ≥ 10 rlu/co compared with a cut-off level of ≥ 1 rlu/co varied by trial, but at their lowest they were 0.97, 0.92, and 0.91, respectively. A similar pattern was observed for cervical intraepithelial neoplasia grade II or higher. The specificity would increase by at least 1%, 2%, and 3%, respectively, so that up to 24%, 39%, and 53%, of positive hybrid capture 2 test results not associated with high grade neoplasia could be avoided. Only two outliers existed to this general pattern.

CONCLUSIONS

Although the data were derived from the baseline screening rounds only, the decrease in the sensitivity for high grade cervical intraepithelial neoplasia using a hybrid capture 2 cut-off level between ≥ 2 rlu/co and ≥ 10 rlu/co seemed acceptable given the international recommendations for testing for human papillomavirus DNA in cervical screening, which require 90% or more sensitivity for cervical intraepithelial neoplasia grade II or higher compared with hybrid capture 2 at ≥ 1 rlu/co. The data suggest that the hybrid capture 2 cut-off level could be increased in primary screening; this seems reasonably safe and is significantly less burdensome for women.

False-positive Human Papillomavirus DNA tests in cervical screening: it is all in a definition

AIM

Based on data from randomised controlled trials (RCT) on primary cervical screening, it has been reported that the problem of more frequent false-positive tests in Human Papillomavirus (HPV) DNA screening compared to cytology could be overcome. However, these reports predominantly operated with a narrow definition of a (false-)positive test. The aim of this paper was to illustrate how the narrow definition affected the measured adverse effects of HPV DNA screening compared with cytology screening.

METHODS

In the European RCT data, we measured the impact of the narrow definition of a positive screening test on the published relative positive predictive values (PPV), an indicator of the relative frequency of false-positive screening tests.

RESULTS

Using the trialists' definitions of positive screening tests, HPV screening combined with cytology triage had relative PPVs of 0.87 (95% confidence interval (CI): 0.60-1.26) for ≥ CIN3 based on Swedish RCT data, and 0.78 (0.52-1.16) for ≥ CIN2 in the Italian Phase 1 RCT (25-34 years). These PPVs changed to 0.44 (0.30-0.64) and 0.51 (0.33-0.79), respectively, when all positive HPV or cytology screening tests were accounted for. In the Finnish RCT data, HPV screening using the cut-off point of ≥ 10 pg/ml had a relative PPV of 0.27 (0.15-0.50) for ≥ CIN3, which changed to 1.84 (0.99-3.41).

CONCLUSION

The relative PPV was incorrectly estimated in six out of seven studies. In three of those six studies, the relative PPV changed significantly after inclusion of the previously erroneously excluded false-positive HPV or cytology tests.

Mammograms and the management of existential discomfort: threats associated with the physicality of the body and neuroticism

The current research employs ideas from terror management theory to investigate why mammograms may be psychologically problematic. This perspective suggests that individuals, particularly those high in neuroticism, are threatened by that which reminds them of their physical and mortal nature. In Study 1, a laboratory experiment demonstrated that when concerns about mortality were primed, reminders of one's physical nature (i.e. creatureliness) led women who were high in neuroticism to report reduced willingness to imagine undergoing a mammogram. In Study 2, a field experiment among women receiving a mammogram showed that priming creatureliness increased perceptions of discomfort with the procedure for women high in neuroticism. Theoretical and practical implications are discussed.

Monitoring a national cancer prevention program: Successful changes in cervical cancer screening in the netherlands

The success of screening, an important cancer prevention tool, depends on the quality and efficiency of protocols and guidelines for screening and follow-up. However, even centrally organized screening programs such as the Dutch cervical screening program occasionally show problems in performance. To improve this program, the screening scheme, follow-up, administration and financing protocols and guidelines were thoroughly changed in 1996. This study evaluates the consequences for the performance of the national program. Five-year coverage rate, the proportion of screened women sent to follow-up, follow-up compliance and duration, and the yearly number of Pap smears before and after the changes in 1996 were compared. Five-year coverage increased substantially in the added target age groups (30-34, and 54-60 years); in the old target age group (35-53 years) it remained around 80%. The percentage of screened women sent to follow-up decreased from almost 19-3% per screening round, due to a more restrictive use of the Pap 2 classification, and an evidence-based cessation of follow-up of negative smears without endocervical cells. Follow-up compliance has improved, and the average time until a woman is either referred or rejoins the regular screening schedule, has become shorter. The total number of smears, a strong determinant of screening costs, has decreased by 20% primarily due to the changed follow-up recommendations. In conclusion, the 1996 changes in protocols and guidelines, and their implementation have increased coverage and efficiency, and decreased the screening-induced negative side effects.

Women's knowledge about breast cancer risk and their views of the purpose and implications of breast screening--a questionnaire survey

OBJECTIVES

To assess women's knowledge and perception of breast screening, including its benefits and disadvantages, and explore whether demographic and other personal characteristics are associated with accurate knowledge.

DESIGN

Questionnaire survey of a random sample of 1000 women aged between 49 and 64 years registered with GPs in Oxfordshire.

RESULTS

Thirty-six per cent of women knew the lifetime risk of developing breast cancer, and the interpretation of numeric risks varied among women. There was an association between inaccurate knowledge and lower formal education (P = 0.05). Forty-five per cent of women believed that screening prevents breast cancer. Women were of the opinion that screening helps early detection, could result in less invasive treatment and reassured them. Sixty-three per cent had no concerns about breast screening. The main causes of concern were that they would not be invited for further screening (exclusively women in their 60s), screening is not offered earlier or more frequently, painful mammography and effects of radiation. A minority of women were concerned that the pressure exerted on the breasts during mammography may itself trigger cancer by displacing and spreading cancer cells.

CONCLUSIONS

Women's knowledge about breast screening was variable and sometimes incorrect, and those with less formal education were more likely to have inaccurate knowledge.

Ovarian carcinoma screening in women at intermediate risk: impact on quality of life and need for invasive follow-up

BACKGROUND

Women with family histories suggestive of an increased risk of ovarian carcinoma who have not had a deleterious BRCA1 or BRCA2 mutation identified are commonly suggested to consider ovarian carcinoma screening with transvaginal ultrasound and/or assessment of CA 125 levels. Limited information is available regarding the impact of this approach on either quality of life (QOL) or need for invasive follow-up in this group of women.

METHODS

From November 1999 to October 2002, 184 women at intermediate risk of ovarian carcinoma were enrolled in a prospective study. Participants were screened with twice yearly transvaginal ultrasound and CA 125 assessments. Impact on QOL was measured using the Mental Component Summary (MCS) score of the Medical Outcomes Studies Short Form-36. Need for invasive follow-up was determined by questionnaire and medical record review.

RESULTS

In the current study, 135 participants underwent > or = 1 follow-up assessment. During a mean of 19.8 months of follow-up, 12.9% of ultrasounds and 3.8% of CA 125 assessments were abnormal. The authors reported that 38.5% of participants had > or = 1 abnormal ovarian screen that required a short interval follow-up. Because of either abnormal bleeding or ultrasound abnormalities, 24% of participants underwent > or = 1 endometrial sampling. Controlling for a history of breast carcinoma and menopausal status, abnormal ovarian screening results were associated with a decrease in MCS score (P = 0.034), whereas the need for endometrial sampling was not (P = 0.87).

CONCLUSIONS

Ovarian carcinoma screening in women at intermediate risk was associated with a substantial rate of abnormal screen results, endometrial sampling, and in women with abnormal ovarian screening findings, a decrease in MCS scores. These findings may have important implications for women considering ovarian carcinoma screening and for the design of future ovarian carcinoma screening trials.

Influence of patient care provider on patient health outcomes in allergic rhinitis

BACKGROUND

Diagnosing and managing the symptoms of allergic rhinitis are largely the responsibility of family physicians and allergists, but some patients choose self-management. However, few data are available to determine how the choice of care relates to measures of patient outcomes, such as the ability to perform activities, quality of life, and productivity.

OBJECTIVE

To examine and compare patients' ability to perform activities, quality of life, productivity, and symptoms according to care provider: family physician, allergist, or self-management.

METHODS

A questionnaire was developed and mailed to 2,065 patients enrolled in a 500,000-member managed care organization. Patients were identified by diagnostic codes for allergic rhinitis as determined from a retrospective examination of medical and prescription claims records between January 1, 2000, and December 31, 2000.

RESULTS

Chi-squared Tests revealed statistically significant differences for symptoms, family history, testing, immunotherapy, and test value among patient care providers. Multivariate analysis of variance revealed statistically significant differences for activities, symptoms, and quality of life among patient care providers. Findings support the use of diagnostic testing to improve patient outcomes. Symptoms were statistically significantly associated with measures of productivity.

CONCLUSIONS

Patient outcomes vary with respect to patient care group. It is imperative that patients suspected of having allergic rhinitis undergo appropriate evaluation and testing. Outcomes can be optimized if allergists and family physicians have access to appropriate diagnostic tools, such as skin testing and serologic tests for specific IgE antibodies.

Socioeconomic status differences in coping with a stressful medical procedure

OBJECTIVE

The objective of this study was to test the hypothesis that socioeconomic disadvantage results in adverse emotional reactions to a novel, stressful, medical examination.

METHODS

Sigmoidoscopy screening for colorectal cancer was identified as a potential stressor. A subset of participants (N = 3535) from the U.K. Flexible Sigmoidoscopy Trial completed pre- and postscreening questionnaires regarding psychologic well-being. All trial participants were sent a postscreening questionnaire after 3 months (post-flexible sigmoidoscopy [FS] sample, N = 29,804), including measures of distress (the General Health Questionnaire), anxiety (State-Trait Anxiety Inventory), a single-item measure of bowel cancer worry, and a 6-item measure of positive consequences of screening. Socioeconomic status (SES) was coded from postcodes with the Townsend Index. SES differences in changes in emotional well-being over the course of screening were evaluated in the longitudinal sample. SES differences in postscreening well-being in relation to screening outcome were evaluated in the post-FS sample.

RESULTS

Bowel cancer worry and anxiety were higher in lower SES groups before screening. Both reduced after screening, but there were no SES differences in the change. In the post-FS sample, there was an SES gradient in anxiety but not in distress. Lower SES groups indicated more positive reactions. There were no interactions between SES and screening outcome for any indicator of well-being.

CONCLUSIONS

Lower SES was associated with worse psychologic well-being before and after screening, but lower SES participants did not show any differentially greater adverse reactions compared with higher SES participants. Moderately stressful experiences in everyday life do not necessarily more unfavorably affect those with fewer educational and economic resources.

Impact of benign breast biopsy upon breast self-examination

Current American Cancer Society guidelines recommend monthly performance of breast self-examination (BSE) for women over 20 years of age. While the experience of a benign breast biopsy can result in elevated levels of distress, the impact of benign biopsy upon breast cancer (BC) screening behavior is not well known. The present study examined frequency of BSE practice in 102 women after benign breast biopsy (biopsy group). Telephone interviews were completed a mean of 21 days (initial interview) and 8 months after biopsy (follow-up interview). A healthy comparison (HC) group of women (n = 76) without a history of breast biopsy completed an initial interview only. Information regarding distress, dispositional characteristics, BC screening-related attitudes and behaviors, and subjective and objective risk for BC was collected. Results indicated that the biopsy and HC groups did not differ in typical (i.e., prebiopsy) practice of BSE. However, practice of BSE changed after biopsy with a general trend toward a decrease in BSE frequency. Only 8% of women in the biopsy group reported appropriate (once per month) practice of BSE at the 8-month Follow-up while 28% reported appropriate practice at the initial interview. Decreases in BSE performance after biopsy were characteristic of younger women, women who lacked confidence in the ability to perform BSE correctly, and women whose biopsy was preceded by discovery of a breast lump or abnormality during BSE. Results suggest the potential value of a psychoeducational intervention after biopsy to enhance appropriate performance of BSE.

Women's experiences of cervical cellular changes: an unintentional transition from health to liminality?

Cervical cancer screening is a preventive intervention directed towards women to both detect cervical cancer and identify those at risk for developing this disease. It has been argued that participation in screening programmes and early detection situations may lead to new kinds of sickness experiences. This article is based on qualitative phenomenological hermeneutical analysis of interviews with women who have received abnormal Pap smear test results through a population-based outreach screening programme in urban Sweden. The aim of this article is to illuminate the meaning, for the participating women, of the lived experience of receiving notification about an abnormal Pap smear result. The data are presented in terms of two themes: Pap smear for routine and recurrent confirmation of health and unexpected and ambiguous communication about Pap smear results. The findings are discussed as an unintentional transition from confirmation of health to liminality. Whereas medical diagnosis has been discussed as structuring the inchoate, an abnormal Pap smear did not create order for the interviewed women. On the contrary, the notification of an abnormal Pap smear created disorder as the women had expected to be confirmed as healthy but instead neither health nor disease were confirmed or excluded. Even 'simple' technology is shown to have an ontological dimension, with the ability to transform daily taken-for-grantedness of ourselves as primarily healthy to (potentially) unhealthy.

Short-term impact of cancer prevention and screening activities on quality of life

PURPOSE

There are few data on the short-term effects of participating in cancer prevention activities, undergoing genetic risk assessment, or having routine screening. The objective of this article is to systematically review existing research on short-term effects of prevention, genetic counseling and testing, and screening activities on quality of life.

METHODS

We conducted a MEDLINE search for original research studies that were published between January 1, 1985, and December 31, 2002, and conducted in North America or Western Europe. Data were abstracted and summarized using a standardized format.

RESULTS

We reviewed 210 publications. Most studies focused on psychological states (anxiety, depression), symptoms, or general health status. One hundred thirty-one studies used 51 previously validated noncancer instruments. Many researchers (12.6%) also added cancer-specific measures, such as perceived cancer risk or symptom indices. Only one study measured satisfaction or quality of provider-client communication. While one report examined lost workdays, no other economic consequences of short-term outcomes were evaluated. Among seven studies that assessed short-term outcomes preferences, only four specifically used time trade-off or linear rating scale methods. No study used standard gamble or willingness-to-pay methods. The overwhelming majority of research indicated that short-term effects were transient. Only two studies linked short-term effects to long-term cancer-related health behaviors such as repeat screening.

CONCLUSION

There is considerable heterogeneity in short-term outcome measurement. Clinicians need to be aware of potential for short-term, transient adverse effects. The impact of short-term experiences should to be linked to long-term health status and use of services.

Trusting technology: women aged 40-49 years participating in screening for breast cancer--an exploratory study

OBJECTIVE

This paper reports key findings from an exploratory study of factors associated with women's decision to participate in mass mammography screening in Tasmania. In particular, we explored factors that contribute to the choice to participate in screening by women who are outside the primary target group, and for whom the evidence of benefit remains contentious.

METHODS

Semi-structured interviews were conducted with a small sample of women aged between 40 and 49 years in rural Tasmania who had participated in mammography screening.

RESULTS

Key ideas that appeared to shape participation included the fear of breast cancer, trust in technology, and taking responsibility for health. Information provision is also an important factor in shaping participation patterns.

CONCLUSIONS AND IMPLICATIONS

In order to facilitate informed consent, information provision in this area should take account of the dominant ideas that shape the decision to participate in breast cancer screening.

Blood Pressure Monitoring: Older Adults' Perceptions

The purpose of this article is to report the qualitative findings on older adults' perceptions of blood pressure measurement and its meaning to their health. The convenience sample consisted of 51 community-dwelling older adults who were recruited from either wellness clinics or a senior citizens' club. Data were collected through in-depth audiotaped interviews. Participants' responses were analyzed by identifying topics, patterns, and themes. The following three themes emerged: provision of reassurance, decision-making leading to self-care activities, and reliance on health care professionals. These findings can be used by community health nurses, especially those in gerontology to gain insight into how a sample of older adults perceived blood pressure monitoring. In addition, the findings can serve as guidelines for nurses in the provision of effective hypertension management with older adults.

Pre- and postmenopausal high-risk women undergoing screening for ovarian cancer: anxiety, risk perceptions, and quality of life

OBJECTIVE

Recommendations for women at high risk of ovarian cancer include prophylactic salpingo-oophorectomy (PSO) or screening with transvaginal ultrasonography (TVUS) and CA125 levels. The best strategy for improving survival and maintaining quality of life in high-risk women is not known. Premenopausal women may be more reluctant than postmenopausal women to undergo PSO. However, the risk of false-positive screening results may be more likely in premenopausal women, posing potential psychological risk for those enrolled in high-risk ovarian cancer surveillance programs. We sought to determine whether anxiety, depression, perception of ovarian cancer risk, and false-positive test frequency differed between high-risk premenopausal and postmenopausal women initiating ovarian cancer screening.

METHODS

High-risk women aged > or = 30 years enrolling in a TVUS plus CA125 ovarian cancer screening study completed standard QOL (SF-36), cancer-specific anxiety (IES), depression (CES-D), and ovarian cancer risk perception measures. CA125 > 35 and TVUS showing solid or complex cystic ovarian masses were considered abnormal. Abnormal tests were repeated after 4-6 weeks. Persistently abnormal tests prompted a search for malignancy. Tests that normalized on repeat were considered false positive.

RESULTS

One hundred forty-seven high-risk women, median age 46 (range, 30-78), 78 premenopausal and 69 postmenopausal, had > or = 1 TVUS/CA125/outcome assessment. Premenopausal women were more likely than postmenopausal women to consider themselves at higher risk of ovarian cancer compared with women their age (P < 0.001) and compared with women with similar family histories (P < 0.001). Mean personal perception of lifetime risk of ovarian cancer among premenopausal women was 37% (range, 0-90%) versus 26% (range, 0-60%) among postmenopausal women (P = 0.02). While general QOL and depression scores were similar, 38% of premenopausal women reported high anxiety versus 27% of postmenopausal women (P = 0.03). Thirty percent of women required repeat CA125 or TVUS after first screening; 10.8% of premenopausal women versus 4.6% of postmenopausal women required repeat CA125; and 23.3% of premenopausal and 20.6% of postmenopausal women required repeat TVUS. One postmenopausal woman with persistently rising CA125 >100 had negative mammography, colonoscopy, and dilation and curettage/bilateral salpingo-oophorectomy. All other abnormal tests normalized on repeat. Two premenopausal women withdrew due to anxiety following false-positive CA125 results. Five women (2 premenopausal, 3 postmenopausal) with normal TVUS/CA125 screening tests elected PSO, with benign findings.

CONCLUSION

Premenopausal women perceive their ovarian cancer risk to be higher, report greater ovarian cancer risk-related anxiety, and are more likely to have false-positive screening results than postmenopausal women. Few high-risk women elect PSO in the short term. Knowledge of the frequency of false-positive screening results and psychosocial outcomes is important for high-risk women choosing strategies for managing ovarian cancer risk.

Receiving a screen-detected diagnosis of cancer: The experience of participants in the UK flexible sigmoidoscopy trial

The experience of receiving a screen-detected diagnosis of colorectal cancer was explored using open-ended interviews. Twenty four people who had been diagnosed with cancer at flexible sigmoidoscopy screening were interviewed at their homes over the telephone. Thematic analysis of the transcripts showed that the experience of gaining a diagnosis of cancer through screening was characterised by a lack of prior expectation that cancer would be detected and feelings of shock. This was largely because of the absence of symptoms and current feelings of well-being. Some interviewees expressed feelings of relief and gratitude at having cancer diagnosed at an early enough stage that 'something could be done about it'. The experience of receiving a screen-detected diagnosis could be summarised as one of 'moderated shock' whereby the shock of the unexpected diagnosis was often moderated by the news that the cancer had been caught early. Whilst these screen-detected cancers were diagnosed relatively rapidly, a significant number of interviewees had a period in which they were effectively 'symptomatic' (e.g. knew they had an adenoma but did not know whether it was malignant or benign). However, they did not use this period to prepare themselves for a possible cancer diagnosis. Raising awareness of the adenoma-carcinoma sequence may help reduce the shock of a screen-detected diagnosis. However, any interventions aimed at reducing the distress of a screen-detected cancer would need to consider the overall benefit to screening attenders, most of whom will have benign polyps detected.

Psychological impact of colorectal cancer screening

This article examines the psychological impact of participating in sigmoidoscopy screening for colorectal cancer prevention. The 1st study examined psychological well-being at 3 months, in relation to screening outcome, in 4,153 individuals. The 2nd study used longitudinal data to examine changes in psychological functioning from before to after screening in relation both to screening outcome and baseline indicators of vulnerability. There were few psychological differences between those who had received negative results or had polyps detected. These findings were confirmed in the longitudinal study, which also found no evidence for vulnerability to adverse effects among those who were initially most anxious or who perceived their risk of cancer to be higher. The longitudinal data suggested that screening might produce transient positive effects.

Does the method of detection of breast cancer affect subsequent psychiatric morbidity?

The aim of this prospective study was to compare the prevalence of psychiatric morbidity following diagnosis of breast cancer between a group of women presenting with screen-detected cancer and a group presenting with symptomatic disease. Psychiatric symptoms were elicited using the Structured Clinical Interview (SCID) and classified according to DSM-III criteria. 61 (46%) of 132 women interviewed experienced an episode of psychiatric disorder between 1 month before diagnosis and 12 months post-diagnosis. There was no association between detection by screening of breast cancer and psychiatric disorder (Odds Ratio (OR) 0.8, 95% Confidence Interval (CI) 0.4-1.8 P=0.7). The occurrence of an episode of psychiatric disorder was associated with a previous history of treatment for psychological problems (OR 2.4, 95% CI 1.1-5.5, P=0.02). The results suggest there is no increased risk of developing psychiatric morbidity associated with the detection of cancer through the National Breast Screening Programme.

Adverse psychological effects in women attending a second-stage breast cancer screening

OBJECTIVE

The purpose of this study was to examine the emotional and psychopathological impact associated with a second-stage screening for breast cancer.

METHOD

We used a short-term longitudinal design. Interviews were conducted with 1195 women of 45-65 years old in three temporal conditions (premammogram, postmammogram, and follow-up). Participants included women attending for regular breast cancer screening who were recalled for a further mammogram (i.e., second-stage breast cancer screening) and women who were not recalled. Affective-cognitive concerns about cancer (worry, fear, and perceived vulnerability) were rated using a 10-point Likert scale. Psychopathology was assessed using the Hopkins Symptom Check List-Revised (SCL-90-R).

RESULTS

Women attending the second-stage screening exhibited significantly higher levels of breast cancer worries, fears, and beliefs than women attending for routine screening before obtaining the results of the mammogram. This affective-emotional impact disappeared quickly and was not relevant 2 months following the mammogram. Despite the fact that levels of psychopathological symptoms were higher in the premammogram condition, there were no differences between groups on these measures.

CONCLUSION

These results provide support for the hypothesis that women recalled for further mammograms tend to experience high levels of affective-cognitive distress but not psychopathological symptoms. Moreover, results do not sustain the prediction that this psychological impact persists beyond receipt of a negative result. Some recommendations to reduce these psychological side effects are suggested.

Psychological adjustment to familial-genetic risk assessment for ovarian cancer: predictors of nonadherence to surveillance recommendations

OBJECTIVE

To evaluate whether self-report measures of psychological distress and perceived risk were associated with nonadherence to recommended ovarian cancer surveillance.

METHODS

Eighty-three patients attending the Familial Ovarian Cancer Clinic (FOCC) at Princess Margaret Hospital were assessed psychosocially prior to and during initial familial-genetic assessment and then monitored for adherence with recommended follow-up surveillance over a period of 12-18 months. The assessment protocol included an investigator-designed clinic questionnaire, the State-Trait Anxiety Inventory (STAI), Center for Epidemiologic Studies Depression Scale (CESD), Life Orientation Test (LOT), Medical Outcomes Study Social Support Survey (MOSSS), Texas Inventory of Grief, and the COPE. Nonadherence was measured in terms of unexplained absences at one or two recommended and scheduled surveillance appointments following the familial-genetic assessment.

RESULTS

Univariate tests revealed a significant association between higher perception of ovarian cancer risk, as assessed immediately after the familial-genetic risk assessment in the clinic and nonadherence to physician-recommended surveillance (chi2 (2, N = 83) = 9.75, P < 0.008). Empirically based estimates of risk, conveyed by the clinic team to subjects, were not significantly associated with nonadherence (chi2 (2, N = 83) = 0.19, P = 0.91). Logistic regression analysis revealed that subjects who perceived themselves to be at high ovarian cancer risk were five times more likely to be nonadherent than participants who perceived themselves to be at low or medium ovarian cancer risk.

CONCLUSIONS

These results suggest that higher self-perceived risk may predict adherence difficulties to recommended surveillance in women attending a familial-genetic risk clinic.

Randomised trial of the psychological effect of information about oral cancer in primary care settings

AIM

To determine the immediate influence of a validated patient information leaflet (PIL) on patient anxiety and intention to have a screen for oral cancer in primary care attenders.

PARTICIPANTS

Patients (n=800) attending their primary health care provider.

SETTING

Fourteen general practices (eight dental and six medical) in the northwest of England.

DESIGN

Randomised controlled trial with two arms: leaflets provided in information group, leaflet was absent in control group.

MEASURES

Single item ratings of (1) intention to have an oral cancer screen, and (2) anxiety towards a screen, (3) perceived risk of oral cancer. Knowledge of oral cancer, self-reported dental service attendance history and demographic variables were also collected.

RESULTS

Patients who had read the oral cancer PIL demonstrated an increase in their intention to have a screen (Mann Whitney U test: z=-3.67, P<0.001) and reduced anxiety (Mann Whitney U test: z=-2.07, P<0.05). Subjective risk was not elevated by the extra information. Intention to have a screen was predicted by knowledge level and anxiety (odds ratios: 1.10 and 0.70 respectively, both P's<0.001).

CONCLUSION

The influence of an information leaflet appeared to have a positive effect on anxiety level and intentions to agree to receive an oral cancer screen.

Considerations in using tumor markers: what the psycho-oncologist needs to know

Tumor markers are measures of biological features of a cancer. By revealing important biological aspects of the tumor, tumor markers can be useful in staging patients, predicting cancer outcomes, and guiding treatments. The psychological consequences of using tumor markers are virtually unknown. In this review article, we draw on clinical studies involving the psychological impact of risk information, screening, prognostic information and surveillance of cancer. Such studies may be helpful in considering possible psychological reactions to tumor marker information in clinical practice.

Psychological adjustment to familial genetic risk assessment: differences in two longitudinal samples

Heritable cancer risk assessment is an increasingly common method of deriving valuable information relevant to deciding on appropriate screening regimens and preventive treatments. Assessments of heritable risk typically include familial-genetic evaluation, where analyses relate family pedigree to cancer risk, and DNA testing, where analyses indicate genetic mutations associated with cancer risk (e.g., BRCA1/BRCA2 mutations) or their absence. In this paper we report on the psychological responses of women given familial-genetic evaluations for ovarian cancer risk. The baseline and 6 to 12 follow-up assessments of an initial clinic-attending cohort of 65 women are compared with the baseline and 9 to 12 follow-up assessments of a second clinic-attending cohort of 60 women. Sizeable differences were found in the prevalence of clinically significant depression in these two physician or self-referred populations, as assessed by the Center for Epidemiological Studies Depression scale and in the mean scores. Hypotheses accounting for these differences are discussed.

An experimental study of influences on the perceived likelihood of seeking genetic testing: "nondirectiveness" may be misleading

It has been suggested that decision making involves the implicit weighing up of those advantages and disadvantages of possible options considered relevant at the time the decision is made. If this is so, the information that people have most readily available at the time of the decision would influence the decision outcome. The study reported here experimentally evaluates the effect of manipulating the issues on which individuals focus as a way of investigating subtle directive influences. Participants (n = 104) were interviewed about their anticipated likelihood of opting for testing for hereditary hemochromatosis. All participants were given standard information about hemochromatosis, including a description of the disorder as causing progressive damage over many years and an explanation that treatment is most effective if begun before the age of 30 years. Individuals were randomly allocated to groups according to age group (30 years and under, or over 30 years) and gender. Those allocated to the positive group were then encouraged to focus on positive aspects of the previously given information by considering the extent to which statements applied to them, whereas the negative group focused on negative aspects. The control group focused on an unrelated disease. Analyses of variance indicated that the focusing manipulation affected the likelihood of opting for testing. This effect interacted with age of respondent: in participants over 30, the positive group ratings of likelihood of testing increased, whereas in the negative group they decreased; in participants 30 and under, both the positive and negative groups showed an increased desire to be tested. The control group did not alter significantly. The relevance of these findings to "nondirective" approaches to genetic counseling is considered.
