What are the sources of distress in a range of cancer caregivers? A qualitative study

The identification and management of unmet supportive care needs is an essential component of health care for people with cancer. Information about the prevalence of unmet need can inform service planning/redesign. A systematic review of electronic databases was conducted to determine the prevalence of unmet supportive care needs at difference time points of the cancer experience. Of 94 articles or reports identified, 57 quantified the prevalence of unmet need. Prevalence of unmet need, their trends and predictors were highly variable in all domains at all time points. The most frequently reported unmet needs were those in the activities of daily living domain (1-73%), followed by psychological (12-85%), information (6-93%), psychosocial (1-89%) and physical (7-89%). Needs within the spiritual (14-51%), communication (2-57%) and sexuality (33-63%) domains were least frequently investigated. Unmet needs appear to be highest and most varied during treatment, however a greater number of individuals were likely to express unmet need post-treatment compared to any other time. Tumour-specific unmet needs were difficult to distinguish. Variations in the classification of unmet need, differences in reporting methods and the diverse samples from which patients were drawn inhibit comparisons of studies. The diversity of methods used in studies hinders analysis of patterns and predictors of unmet need among people with cancer and precludes generalisation. Well-designed, context-specific, prospective studies, using validated instruments and standard methods of analysis and reporting, are needed to benefit future interventional research to identify how best to address the unmet supportive care needs of people with cancer.

Objective To quantify the link between lower, subclinically symptomatic, levels of psychological distress and cause-specific mortality in a large scale, population based study. Design Individual participant meta-analysis of 10 large prospective cohort studies from the Health Survey for England. Baseline psychological distress measured by the 12 item General Health Questionnaire score, and mortality from death certification. Participants 68 222 people from general population samples of adults aged 35 years and over, free of cardiovascular disease and cancer, and living in private households in England at study baseline. Main outcome measures Death from all causes (n=8365), cardiovascular disease including cerebrovascular disease (n=3382), all cancers (n=2552), and deaths from external causes (n=386). Mean follow-up was 8.2 years (standard deviation 3.5). Results We found a dose-response association between psychological distress across the full range of severity and an increased risk of mortality (age and sex adjusted hazard ratio for General Health Questionnaire scores of 1-3 v score 0: 1.20, 95% confidence interval 1.13 to 1.27; scores 4-6: 1.43, 1.31 to 1.56; and scores 7-12: 1.94, 1.66 to 2.26; P<0.001 for trend). This association remained after adjustment for somatic comorbidity plus behavioural and socioeconomic factors. A similar association was found for cardiovascular disease deaths and deaths from external causes. Cancer death was only associated with psychological distress at higher levels. Conclusions Psychological distress is associated with increased risk of mortality from several major causes in a dose-response pattern. Risk of mortality was raised even at lower levels of distress.
