Impact of early access to a palliative/supportive care intervention on pain management in patients with cancer.

BACKGROUND: No study has so far addressed whether differences do exist in the management of cancer pain between patients receiving usual care by primary specialists and those receiving early palliative/supportive intervention. PATIENTS AND METHODS: A multicentre cross-sectional study in 32 Italian Hospitals has included 1450 patients, receiving analgesic therapy for cancer pain: 602 with access to primary specialist alone (standard care, SC) and 848 with early access to a palliative/supportive care (ePSC) team, concomitant with primary oncology care. RESULTS: Statistically significant differences in the analgesic drug administration according to care model have been evident: non-opioids were more frequently used in SC (9.5% versus 2%; P<0.001), while strong opioids in ePSC group (80% versus 63%; P<0.001). The number of patients with severe pain was lower in ePSC compared with SC group (31% versus 17%; P<0.001). Results of multivariate analysis have shown that ePSC integrated with primary oncologic care (relative risk 0.69; 95% confidence interval 0.48-0.99; P=0.045) was an independent factor associated with a 31% reduced risk of suffering from severe pain. CONCLUSIONS: An ePSC team provides the most effective standard of analgesic therapy for cancer pain. A randomized clinical trial is needed to confirm these findings.

Patients' opinions, feelings, and attitudes after a campaign to promote the Di Bella therapy.

BACKGROUND: An emotional campaign promoting the Di Bella cancer therapy was launched by the Italian media in 1997. Its effects on patients' hopes, feelings, and decision-making processes were largely unknown. We undertook an investigation of this issue. METHODS: Between Feb 25 and March 31, 1998, a ten-item questionnaire was distributed to 1300 unselected adult patients attending 13 cancer centres throughout Italy. Four expert psycho-oncologists reviewed the design and validity of the contents of the questionnaire. Sociodemographic information was also collected. FINDINGS: 1120 (86%) questionnaires were returned and analysed. The main sources of information were television/radio (62%) and newspapers (26%); only 5% cited doctors. The campaign induced optimism in the patients about the efficacy of the method (ineffective 1%, effective 42%, uncertain 57%), and 53% said their hope of cure was increased. However, 48% felt more confused. 24% do not discuss new treatments with their oncologists, and 20% would like to but cannot. When choosing a treatment, the advice of a trusted doctor was judged more important than scientific progress (53% vs 32%) and 63% would try even unproven treatments in the hope of a cure. Replies to many of the questions were influenced by patients' educational attainment and by the degree of communication with their oncologists. INTERPRETATION: Science cannot prevent the harm caused by such campaigns and their psychological consequences, particularly for less educated patients. When making decisions, patients are looking for hope from the treatment and trust in their doctor, both of which depend on effective doctor-patient communications that therefore need to be improved.

Shape constancy: a systematic approach.

This work contains the analysis of one experiment and its results. It was carried out to demonstrate that: (i) Shape is a shape-constancy 'factor'. In other words, there must be a 'shape-constancy scale' where the various shpaes can be arranged; (ii) when the shape factor is isolated, the shape constancy of a visual pattern is directly proportional to the strength of the 'linear-perspective cue' and inversely proportional to its degree of 'simplicity'. A pattern such as the cross (which has many linear components and a high degree of complexity) should therefore exhibit a maximum of constancy. The results of the experiment have confirmed the above hypothesis except for an unexpected low degree of constancy of the cross. Another experiment is being performed to explain this last result.
