The screening history of women with cervical cancer in the Rotterdam area

The family experiences of in-hospital care questionnaire in severe traumatic brain injury (FECQ-TBI): a validation study

BACKGROUND

Family members are important for support and care of their close relative after severe traumas, and their experiences are vital health care quality indicators. The objective was to describe the development of the Family Experiences of in-hospital Care Questionnaire for family members of patients with severe Traumatic Brain Injury (FECQ-TBI), and to evaluate its psychometric properties and validity.

METHODS

The design of the study is a Norwegian multicentre study inviting 171 family members. The questionnaire developmental process included a literature review, use of an existing instrument (the parent experience of paediatric care questionnaire), focus group with close family members, as well as expert group judgments. Items asking for family care experiences related to acute wards and rehabilitation were included. Several items of the paediatric care questionnaire were removed or the wording of the items was changed to comply with the present purpose. Questions covering experiences with the inpatient rehabilitation period, the discharge phase, the family experiences with hospital facilities, the transfer between departments and the economic needs of the family were added. The developed questionnaire was mailed to the participants. Exploratory factor analyses were used to examine scale structure, in addition to screening for data quality, and analyses of internal consistency and validity.

RESULTS

The questionnaire was returned by 122 (71%) of family members. Principal component analysis extracted six dimensions (eigenvalues > 1.0): acute organization and information (10 items), rehabilitation organization (13 items), rehabilitation information (6 items), discharge (4 items), hospital facilities-patients (4 items) and hospital facilities-family (2 items). Items related to the acute phase were comparable to items in the two dimensions of rehabilitation: organization and information. All six subscales had high Cronbach's alpha coefficients >0.80. The construct validity was confirmed.

CONCLUSION

The FECQ-TBI assesses important aspects of in-hospital care in the acute and rehabilitation phases, as seen from a family perspective. The psychometric properties and the construct validity of the questionnaire were good, hence supporting the use of the FECQ-TBI to assess quality of care in rehabilitation departments.

Patients with cervical cancer: why did screening not prevent these cases?

OBJECTIVE

The objective of the study was to assess the screening history of women with cervical cancer and review normal cervical smears 5 years preceding the diagnosis.

STUDY DESIGN

Cytological and histological results of 401 women treated for invasive cervical cancer between 1991 and 2008 at the Radboud University Nijmegen Medical Center were studied. Ninety-eight normal smears were reviewed.

RESULTS

Of the 401 women, 269 (67%) received at least 1 invitation for the national screening program for cervical cancer (NCSP). One- third fell outside the target age of the NCSP. Seventeen percent never responded to the invitation(s). Twenty-one percent had 1 or more normal smears within 5 years preceding the diagnosis. After review, only 39% of those smears were reviewed as a normal smear.

CONCLUSION

Half of the women with cervical cancer were never screened because of the limited target age range or nonattendance. Twenty-one percent had a normal smear within 5 years preceding the diagnosis, caused by interpretation and/or sampling errors.

Screening history of women with invasive cervical cancer in north-east Italy

OBJECTIVES

To describe screening histories of women with invasive cervical cancer (ICC) in Friuli Venezia Giulia, after the introduction of organized screening, in order to identify possible reasons undermining prevention of ICC. To investigate associations between screening histories in relation to women's survival and tumor characteristics, with a focus on organized and opportunistic screenings.

STUDY DESIGN

438 women, diagnosed with ICC between 1999 and 2005, were identified using the regional Cancer Registry. Cytological and histopathological information were obtained through regional health databases. Associations between different screening histories and characteristics of women and their tumors were evaluated by means of odds ratios (OR) and corresponding 95% confidence intervals (CI), through multinomial logistic regression models adjusted for age; death risks were estimated by computing hazard ratios (HR) with 95% CI, using Cox models adjusted for age, tumor stage, and histology.

RESULTS

165 (38%) women with ICC had no Pap smears: 71 (16%) never attended the organized screening despite invitation; 69 (16%) were never invited because they were above 64 years of age; and 25 (6%) were yet to be invited. Conversely, 273 (62%) women underwent screening: 141 women (32%) had opportunistic screening; 132 (30%) women attended the organized program. A total of 193 (44%) women had ICC detected at screening. Compared to women with ICC who had never been screened, those screened within the organized program were more often at stage IA (46%), were seldom at stage II or higher (OR=0.3, 95% CI: 0.1-0.6, vs. IB), and showed a lower risk of death (HR=0.6, 95% CI: 0.3-1.0).

CONCLUSIONS

In Friuli Venezia Giulia, the lack of screening among older women and of compliance with organized programs among women in the target population are the main limitations in cervical cancer secondary prevention. Our findings indicate that participation in organized screening has a beneficial effect in terms of down-staging and improved survival as compared to both absence of screening and opportunistic screening.

Superior performance of liquid-based versus conventional cytology in a population-based cervical cancer screening program

OBJECTIVE

Liquid-based cytology may offer improvements over conventional cytology for cervical cancer screening. The two cytology techniques were compared in a group of 86,469 women who participated in a population-based screening program. Using a nation-wide pathology database containing both cervical cytology and histology records for all patients, we compared the outcome of the two screenings methods with regard to the detection rate of histological proven abnormalities and the determination of the true false-negative rates for both methods.

METHODS

Two cohorts of women living in the same geographical region were used. Cohort 1 (n=51,154 women) was analysed using conventional cytology (conventional cohort) and cohort 2 (liquid cohort) (n=35,315 women) was analysed using liquid-based cytology (SurePath). The samples were processed in one laboratory. The results of histological follow up were available via a central database.

RESULTS

The rate of unsatisfactory slides was significantly lower using liquid-based cytology (0.13% vs. 0.89%, p<0.0001). Detection of ASCUS+ (Atypical squamous cells of unknown significance or higher abnormalities) was significantly higher using liquid-based cytology (2.97% vs. 1.64%, p<0.0001), mainly due to the increase in the ASCUS category. The percentage of histological abnormalities within the ASCUS samples was approximately equal in both cohorts, indicating that more true abnormal cases were detected using liquid-based cytology. The sensitivity for detection of a histological proven lesion is significantly higher in the liquid cohort compared to the conventional cohort (96.2% vs. 92.0%), with only a slight difference in specificity (97.8% vs. 98.2%).

CONCLUSION

This population study confirmed previous institution-based reports of decreased numbers of unsatisfactory samples based on liquid-based cytology and showed an increased sensitivity for the detection of cytological abnormalities that was validated by subsequent histological investigation.

Process of care failures in invasive cervical cancer: systematic review and meta-analysis

OBJECTIVE

As invasive cervical cancer is preventable when screening and treatment of pre-invasive lesions are timely and appropriate, several past studies attempted to enumerate the quality of preventive care invasive cervical cancer subjects received before diagnosis. Objectives of the present study were to review and to summarize the findings of these studies in a meta-analysis.

METHOD

Data from 42 studies were used to estimate DerSimonian and Laird random effects models for the various failures in care along the cancer care continuum. Analyses were also conducted within strata characterized by variables deemed to account for heterogeneity in meta-regression analyses.

RESULTS

Poor Pap screening frequency was the primary factor attributable to development of invasive cervical cancer. On average, 53.8% (95% confidence interval: 43.6-66.3) of invasive cervical cancer subjects had inadequate screening histories and 41.5% (95% confidence interval: 35.4-48.7) were never screened. There was significant temporal improvement in the proportion of women screened at least once over a lifetime but not in the proportion with overall deficient histories. An estimated 29.3% (95% confidence interval: 21.2-40.4) of failures to prevent invasive cervical cancer can be attributed to false-negative Pap smears and 11.9% (95% confidence interval: 9.0-15.6) to poor follow-up of abnormal results.

CONCLUSION

Appropriate assessment of the effect of combined failures in the process of care must be done in comprehensive audit studies.

The role of education in the uptake of preventative health care: the case of cervical screening in Britain

This paper reports findings on the relationship between education and the take-up of screening for cervical cancer, as an example of preventative health-care activity. Theoretically, education can enhance the demand for preventative health services by raising awareness of the importance of undertaking regular health check-ups and may also improve the ways in which individuals understand information regarding periodical tests, communicate with the health practitioner, and interpret results. Furthermore, education enhances the inclusion of individuals in society, improving self-efficacy and confidence. All these factors may increase service uptake. The empirical analysis uses data from the British Household Panel Survey (BHPS) and applies techniques for discrete panel data to estimate the parameters of the model. Results show that adult learning leading to qualifications is statistically associated with an increase in the uptake of screening. The marginal effect indicates that participation in courses leading to qualifications increases the probability of having a smear test between 4.3 and 4.4 percentage points. This estimate is strongly robust to time-invariant selectivity bias in education and the inclusion of income, class, occupation, and parental socio-economic status. These findings enrich existing evidence on the socio-economic determinants of screening for cervical cancer and enable policy makers to better understand barriers to service uptake.

In vitro conventional cytology historical strengths and current limitations

Despite the fact that cervical cytology screening programs have dramatically reduced the prevalence of cervical cancer in the US, women continue to develop and die from the disease. The most important observation contributing to this failing is that 60% of women with invasive cancer have not had a Pap smear in the previous 5 years (or have never had one). The most clinically effective and cost effective approach to reducing the incidence of cervical cancer is to screen the unscreened population. Recent evidence has also noted that the sensitivity of conventional cytology is also much lower than was previously believed. Much recent investigation has been directed at identifying the reasons for this low sensitivity and identifying ways to improve it. Only by improving the sensitivity of cervical cancer screening and participation in screening programs can the prevalence, morbidity, and mortality from cervical cancer be further reduced.
