Waiting times for radiotherapy: variation over time and between cancer networks in southeast England
Robinson D Massey T Davies E Jack RH Sehgal A Møller H 《British journal of cancer》2005,92(7):1201-1208
The aim of this study was to investigate variations in the length of time that patients with cancer wait from diagnosis to treatment with radiotherapy. A total of 57,426 men and 71,018 women diagnosed with cancer between 1992 and 2001 and receiving radiotherapy within 6 months of diagnosis were identified from the Thames Cancer Registry database. In total, 12 sites were identified for which a substantial number or proportion of patients received radiotherapy: head and neck, oesophagus, colon, rectum, lung, nonmelanoma skin cancer, breast, uterus, prostate, bladder, brain and non-Hodgkin's lymphoma. Median waiting times from diagnosis to radiotherapy were calculated, together with the proportion of patients who received radiotherapy within 60 days of diagnosis, and analysed by year of diagnosis, cancer site, deprivation quintile, age at diagnosis, sex and cancer network of either residence or treatment. Logistic regression was used to adjust the proportion receiving treatment within 60 days for the effects of the other factors. There were significant differences in the proportions receiving radiotherapy within 60 days between different networks and different cancer sites, which remained after adjustment. Median waiting times varied from 42 to 65 days across networks of residence, with the adjusted proportion treated within 60 days ranging from 44 to 71%. There was no difference between male and female patients after adjustment for the other factors, particularly site. There was a highly significant trend over time: the median wait increased from 45 days in 1992 to 76 days in 2001, while the adjusted proportion being treated within 60 days declined by almost a half, from 64 to 35%, over the same period. 相似文献

The relative survival of COPD patients on long-term oxygen therapy in Australia: A comparative study 总被引:5,自引:0,他引:5
OBJECTIVE: The survival of patients with COPD on long-term oxygen therapy (LTOT) has been studied using both univariate and multivariate procedures. There has been only one previous report of relative survival. Relative survival takes into account the risk of death due to increasing age. The objective of this study was to determine the relative survival of a group of South Australian patients prescribed home oxygen therapy for COPD. METHODOLOGY: A method proposed by Hakulinen was used to determine relative survival. The results were compared with the relative survival of a similar group of French COPD patients. RESULTS: A total of 505 COPD patients (249 males, 256 females) were included in the survival analysis. Relative survival corrected for life expectancy was 78.1%, 56.7%, 23.1% and 1.1% at 1, 2, 5 and 10 years, respectively, which was less than that reported in a recent French study of comparable patients. Our patients were similar with respect to age, severity of hypoxaemia and oxygen usage to those in the French study. CONCLUSIONS: Using relative survival analysis, Australian LTOT patients with COPD have worse outcomes than some European patients. Factors contributing to the excess mortality in South Australian COPD patients need to be investigated. 相似文献

Purpose: Regional variations and temporal trends in the incidence of new‐onset epilepsy are clinically important and may offer clues on how to prevent epilepsy. Methods: We examined regional differences and secular trends in the incidence of new‐onset epilepsy in the Finnish population based on the nationwide full‐refundable antiepileptic drug registry and the population registry in the years 1986–2008. Key Findings: The overall incidence of epilepsy was significantly higher in eastern Finland than in middle [risk ratio (RR) 1.08 (95% confidence interval, CI 1.05–1.12)), p < 0.0001] and western Finland [RR 1.32 (1.30–1.35), p < 0.0001] but it was declining from 1986 to 2008 in all regions [RR 0.83 (0.81–0.84), p < 0.0001]. The mean annual decline was 0.6%. Although the incidence of epilepsy was falling from 1986 to 2008 in childhood [annual decline 1.9%, RR 0.80 (0.75–0.86), p < 0.0001] and in middle age [annual decline 0.8%, RR 0.88 (0.84–0.93), p < 0.0001], it increased significantly in the elderly (age 65 years or older) in all of Finland [annual increase 3.5%, RR 1.25 (1.18–1.33), p < 0.0001], and particularly in east versus west Finland [RR 1.48 (1.42–1.55), p < 0.0001]. As a result, starting with the year 2000, the incidence rate of epilepsy was higher in the elderly than in children for all of Finland. Significance: In view of the falling incidence of epilepsy in childhood and middle‐age in all of Finland from 1986 to 2008, the significant increase in the incidence of epilepsy in the elderly is of concern. The regional increase of epilepsy may offer clues for allocating resources and, possibly, population epileptogenesis between west and east Finland and for strategies to prevent epilepsy in the elderly. 相似文献

Temporal lobe epilepsy (TLE) has been associated with the phenomenon of accelerated long-term forgetting (ALF), in which memories are retained normally over short delays but are then lost at an accelerated rate over days or weeks. The causes of ALF, and whether it represents a consolidation deficit distinct from the one associated with forgetting over short delays, remain unclear. In addition, methodological issues have made results of some previous studies difficult to interpret. This study used improved methodology to investigate the role of seizure activity in ALF. Forgetting was assessed in participants with TLE (who have involvement of temporal lobe structures) and idiopathic generalised epilepsy (IGE; in which seizures occur in the absence of identified structural pathology in the temporal lobes). Learning of novel stimuli was matched between patients with TLE, patients with IGE and healthy controls matched for age and IQ. Results indicated that the TLE group showed accelerated forgetting between 30-min and three-weeks, but not between 40-s and 30-min. In contrast, rates of forgetting did not differ between patients with IGE and controls. We conclude that (1) ALF can be demonstrated in TLE in the absence of methodological confounds; (2) ALF is unlikely to be related to the experience of epilepsy that does not involve the temporal lobes; (3) neither seizures during the three-week delay nor polytherapy was associated with ALF. 相似文献
