Days spent in acute care hospitals at the end of life of cancer patients in four Swiss cantons: a retrospective database study (SAKK 89/09).

Number of days spent in acute hospitals (DAH) at the end of life is regarded as an important care quality indicator for cancer patients. We analysed DAH during 90 days prior to death in patients from four Swiss cantons. Claims data from an insurance provider with about 20% market share and patient record review identified 2086 patients as dying of cancer. We calculated total DAH per patient. Multivariable generalised linear modelling served to evaluate potential explanatory variables. Mean DAH was 26 days. In the multivariable model, using complementary and alternative medicine (DAH = 33.9; +8.8 days compared to non-users) and canton of residence (for patient receiving anti-cancer therapy, Zürich DAH = 22.8 versus Basel DAH = 31.4; for other patients, Valais DAH = 22.7 versus Ticino DAH = 33.7) had the strongest influence. Age at death and days spent in other institutions were additional significant predictors. DAH during the last 90 days of life of cancer patients from four Swiss cantons is high compared to most other countries. Several factors influence DAH. Resulting differences are likely to have financial impact, as DAH is a major cost driver for end-of-life care. Whether they are supply- or demand-driven and whether patients would prefer fewer days in hospital remains to be established.

Treatment of breast cancer in the elderly: a prospective, population-based Swiss study.

OBJECTIVES: The primary objective of this population-based study is to describe the patterns of care of elderly patients with breast cancer (BC), and evaluate potential causative factors for the decrease in BC-specific survival (BCSS) in the elderly. PATIENTS AND METHODS: We included all or representative samples of patients with newly diagnosed BC from seven Swiss cancer registries between 2003 and 2005 (n=4820). Surgical and non-surgical BC treatment was analyzed over 5 age groups (<65, 65 to <70, 70 to <75, 75 to <80 and ≥80years), and the predictive impact of patient age on specific treatments was calculated using multivariate logistic regression analysis. RESULTS: The proportion of locally advanced, metastatic and incompletely staged BC increased with age. The odds ratio for performing breast-conserving surgery (BCS) in stages I-II BC (0.37), sentinel lymph node dissection (SLND) in patients with no palpable adenopathy (0.58), post-BCS radiotherapy (0.04) and adjuvant endocrine treatment (0.23) were all in disfavor of patients ≥80years of age compared to their younger peers. Only 36% of patients ≥80years of age with no palpable adenopathy underwent SLND. In the adjusted model, higher age was a significant risk factor for omitting post-BCS radiotherapy, SLND and adjuvant endocrine treatment. CONCLUSIONS: This study found an increase in incomplete diagnostic assessment, and a substantial underuse of BCS, post-BCS radiotherapy, SLND and adjuvant endocrine treatment in elderly patients with BC. There is a need for improved management of early BC in the elderly even in a system with universal access to health care services.

Changing patterns of cancer incidence in the early- and late-HAART periods: the Swiss HIV Cohort Study.

BACKGROUND: The advent of highly active antiretroviral therapy (HAART) in 1996 led to a decrease in the incidence of Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), but not of other cancers, among people with HIV or AIDS (PWHA). It also led to marked increases in their life expectancy. METHODS: We conducted a record-linkage study between the Swiss HIV Cohort Study and nine Swiss cantonal cancer registries. In total, 9429 PWHA provided 20,615, 17,690, and 15,410 person-years in the pre-, early-, and late-HAART periods, respectively. Standardised incidence ratios in PWHA vs the general population, as well as age-standardised, and age-specific incidence rates were computed for different periods. RESULTS: Incidence of KS and NHL decreased by several fold between the pre- and early-HAART periods, and additionally declined from the early- to the late-HAART period. Incidence of cancers of the anus, liver, non-melanomatous skin, and Hodgkin's lymphoma increased in the early- compared with the pre-HAART period, but not during the late-HAART period. The incidence of all non-AIDS-defining cancers (NADCs) combined was similar in all periods, and approximately double that in the general population. CONCLUSIONS: Increases in the incidence of selected NADCs after the introduction of HAART were largely accounted for by the ageing of PWHA.
