Cervical cancer survivors and health care use: A Danish population-based register study.

OBJECTIVE: To evaluate the impact of a cervical cancer (CC) diagnosis on use of health care and prescription drugs. METHODS: This population-based register-study included Danish women aged 23-59 years and diagnosed with CC in 2001-2005. Women with a cervical screening outcome were used as comparison group. We obtained number of contacts to general practitioners (GPs), hospitals, psychologists/psychiatrists and defined daily doses (DDD) of analgesic/psychotropic prescription drugs. A difference-in-differences-design was used to estimate effect of a CC diagnosis on health-care use from five-year periods before and after the diagnosis/screening outcome. RESULTS: In total, 926 women with CC and 1,004,759 women without cancer were included. In five years following the date of CC diagnosis, CC patients had increased their use of GPs with 8.6 (95% CI 4.8-12.4) contacts more than women in the comparison group, and with 4.12 (95% CI 3.99-4.25) more hospital contacts. In contrast, use of psychologists/psychiatrists was low and largely unaffected by the CC diagnosis. For use of prescription drugs, analgesics increased with 80 (95% CI 60-100) DDD more in CC patients than in comparison women, and for psychotropics with 304 (95% CI 261-347) DDD more. CONCLUSIONS: A CC diagnosis was followed by an increase in use of GPs, hospitals, and analgesic/psychotropic prescription drugs, while use of psychologist/psychiatrist was largely unaffected. This pattern may indicate that pain/mental health concerns after CC either persisted or were alleviated by other means only.

Abnormal cervical cytology and health care use: a population-based register study.

OBJECTIVE: This study aimed to assess the long-term use of health care services in women with abnormal cytology results compared to women with normal cytology results. METHODS: We did a nationwide population-based study, using women aged 23 to 59years participating in the national organized cervical cancer screening program. We included a study population of 40,153 women with abnormal cytology (exposed) and 752,627 women with normal cytology (non-exposed). We retrieved data from the Danish Civil Registration System, the Danish Pathology Data Bank, the National Health Service, the National Patient and the National Prescription Register. We calculated the frequencies of contacts to general practitioner (GP), to private psychiatrist and/or psychologist, admissions to hospitals and use of prescription drugs. These frequencies were calculated separately in the 5-year period "before" the cytology result and for the 5-year period "after" the result. RESULTS: During the "before" period exposed women had more contacts to GPs, more contacts to psychologists/psychiatrist, and more hospital admissions than non-exposed women. In both exposed and non-exposed women, health care use increased from the "before" to the "after" period. This increase was significantly higher for exposed than non-exposed women regarding contacts to GP, admissions to hospitals, and drug use. CONCLUSION: Women with abnormal cytology results constitute a selected group with a higher health care use than other women even before they have the abnormal cytology. This difference is further enhanced after the abnormal cytology result.

Cervical cancer screening at crossroads.

Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT) demonstrated that HPV testing provides better protection against cervical cancer than cytology, but it requires extra repeated testing. HPV vaccination RCTs, furthermore, have proved that HPV vaccination protects against vaccine-type high-grade CIN in women vaccinated prior to sexual activity, but less so in women vaccinated later. The challenge now is therefore to find an algorithm for screening of a heterogeneous population including non-vaccinated women; women vaccinated prior to start of sexual activity; and women vaccinated later.
