Are treatment effects consistent with hypothesized mechanisms of action proposed for postoperative delirium interventions? Reanalysis of systematic reviews.

Aim: Postoperative delirium (POD) is associated with increased morbidity and is poorly understood. The aim of this review was to identify putative mechanisms through re-analysis of randomized trials on treatment or prevention of POD. Materials & methods: A systematic review was performed to identify systematic reviews of treatments for POD. Constituent randomized controlled trials were identified, and interventions were grouped according to hypothesized mechanisms of action. Effects were meta-analyzed by hypothesized mechanism and timing of intervention. Results: A total of 116 randomized controlled trials described 47 individual interventions for POD, with nine mechanisms identified. The largest effects were observed for postoperative inflammation reduction, and preoperative reinforcement of sleep-wake cycle. Conclusion: This approach identifies treatments focused on mechanisms of action that may be front runners for future trials and interventions.

Patient-reported reasons for delay in diagnosis of age-related macular degeneration: a national survey.

OBJECTIVES: To investigate whether people with age-related macular degeneration (AMD) are able to self-detect symptoms and, if so, what symptoms they experience, from whom they first seek help, whether help is sought within the 1 week recommended by the Royal College of Ophthalmologists' guidelines and reasons for any delay. METHODS AND ANALYSIS: A retrospective, cross-sectional survey design. Postal surveys were sent to 4000 members of the UK Macular Society. Inclusion criteria were participants aged >50 years at diagnosis of AMD with diagnosis after August 2008; criteria were met by 621 respondents. The main outcome was reasons for delays in diagnosis for wet AMD. Data were analysed using χ2 and conventional content analysis. RESULTS: Only one third (n=199; 32%) of respondents were able to self-detect symptoms. In line with national guidance, over half (n=131; 64%) of those self-detecting symptoms sought help promptly. For those whose initial diagnosis was delayed more than 1 week, 27% had potentially treatable wet AMD requiring urgent treatment to prevent vision loss. Reasons for delay reflected individual & service-related issues, including AMD not being detected in the initial consultation, and individuals not perceiving the urgency for symptom investigation. CONCLUSION: In practice most patients sought help within 1 week; however, potentially sight-damaging delays occurred from symptom onset to diagnosis. Suggestions for reducing delay include increasing population awareness of AMD symptoms, the need for urgent detection and close monitoring for AMD and signposting patients to appropriate support services to ensure prompt detection of any future signs of wet AMD.

Healthcare experiences of patients with age-related macular degeneration: have things improved? Cross-sectional survey responses of Macular Society members in 2013 compared with 1999.

OBJECTIVE: To investigate healthcare experiences of patients with age-related macular degeneration (AMD) and determine whether a previous survey and Royal College of Ophthalmologists (RCOphth) management guidelines brought improvements. DESIGN: Cross-sectional survey of Macular Society members in 2013 compared with previous 1999 survey. SETTING: UK Postal Questionnaires. PARTICIPANTS: 1169 respondents in 2013 (1187 in 1999). INTERVENTION: Publication of 1999 survey results (2002), and RCOphth AMD guidelines (2009). MAIN OUTCOME MEASURES: Respondents answered questions about experiences at diagnosis. Five questions were replicated from the 1999 survey for direct comparison in the 2013 survey which included additional questions based on 2009 RCOphth recommendations for information and support provision for patients with AMD. RESULTS: Most 2013 survey respondents were given the name of their macular condition (91%), felt the healthcare professional was interested in them (71%) and were satisfied overall with the diagnostic consultation (76%). These outcomes show significant improvement since 1999. Within the 2013 sample, multivariable analyses showed gradual trends of improvement over time in: provision of written information, Macular Society information and receiving appropriate help, support and advice at diagnosis. Only overall satisfaction with the diagnostic consultation (but not the other nine areas of information and support provision studied) significantly improved in the time after publication of the RCOphth 2009 guidelines. There were no significant improvements associated with the publication of the 1999 survey results. Low information and support provision remained, for example, 44% of respondents diagnosed after the RCOphth 2009 guidelines reported not receiving information on what to do if vision deteriorated. Lack of such information at diagnosis was significantly associated with registration as sight impaired (p<0.01). Reports of general practitioner (GP) knowledge of AMD remained low: 39% reported their GP was 'not at all well informed'. The 2013 respondents reported lower levels of help and support from GPs than 1999 respondents (p<0.001). CONCLUSIONS: Patients diagnosed with AMD after 1999 (vs before 1999) reported better experiences at diagnostic consultation. However, information and support provision at diagnosis, and satisfaction with GPs remained low.

Quantitative evaluation of an information leaflet to increase prompt help-seeking for gynaecological cancer symptoms.

BACKGROUND: Provision of written information may improve awareness of cancer symptoms and encourage timely presentation in primary care. This study assessed changes in symptom knowledge, perceived barriers to help-seeking, anxiety and intention to seek help, following exposure to a leaflet to raise awareness of gynaecological cancer symptoms. METHODS: Women (N = 484) completed questionnaires before and after reading the leaflet. The primary outcome was change in anticipated time to help-seeking for 12 symptoms. Changes in symptom knowledge, barriers and anxiety, and their association with prompt help-seeking were evaluated using Wilcoxon signed rank tests and logistic regression analyses. RESULTS: After reading the leaflet, symptom knowledge increased (p < 0.001), and perceived barriers (p < 0.001) and anxiety (p = 0.008) decreased. The number of symptoms for which women anticipated seeking help promptly increased (p < 0.001). Changes in knowledge (OR 4.21, 95 % CI 1.95-9.13) and perceived barriers (OR 4.60, 95 % CI 1.91-11.04) were independently associated with increased help-seeking. CONCLUSION: Increased symptom knowledge and lowered perceived barriers were related to increased prompt anticipated help-seeking. This occurred without an increase in anxiety. This intervention is effective in altering knowledge, beliefs and help-seeking intentions for gynaecological cancer symptoms, at least in the short-term, and should be trialled in primary care.

Using a Whole Person Approach to Support People With Cancer: A Longitudinal, Mixed-Methods Service Evaluation.

Introduction Improved models of care are needed to meet all the support needs of people with cancer, which encompass psychological, emotional, physical, spiritual, sexual, occupational, social and existential needs. The aim of this article is to (a) evaluate short- and long-term impacts of using a whole person approach to support people with cancer on the Living Well with the Impact of Cancer Course (LWC) and (b) use these data to inform strategic decisions about future service provision at Penny Brohn UK. Methods Longitudinal mixed-methods service evaluation (n = 135). Data collected included health-related quality of life (HRQoL) (FACIT-SpEx); Concerns (types and severity-MYCaW); lifestyle behavior (bespoke questionnaire), and participants' experiences over 12 months postcourse. Results Statistically and clinically significant improvements from baseline to 12 months in severity of MYCaW Concerns (n = 64; P < .000) and mean total HRQoL (n = 66; P < .000). The majority of MYCaW concerns were "psychological and emotional" and about participants' well-being. Spiritual, emotional, and functional well-being contributed most to HRQoL improvements at 12 months. Barriers to maintaining healthy lifestyle changes included lack of support from family and friends, time constraints, and returning to work. Three to 6 months postcourse was identified as the time when more support was most likely to be needed. Conclusions Using a whole person approach for the LWC enabled the needs of participants to be met, and statistically and clinically significant improvements in HRQoL and MYCaW Concerns were reported. Qualitative data analysis explored how experiencing whole person support enabled participants to make and sustain healthy lifestyle changes associated with improved survivorship. Barriers experienced to making health behavior change were also identified. These data then informed wider and more person-centered clinical provision to increase the maintenance of positive long-term behavior changes. Comparison of whole person approaches to cancer treatment and support and standard care are now urgently needed.

Increasing awareness of gynecological cancer symptoms and reducing barriers to medical help seeking: does health literacy play a role?

Health literacy may influence the efficacy of print-based public health interventions. A key part of the U.K. cancer control strategy is to provide information to the public on earlier diagnoses with a view to improving the United Kingdom's relatively poor 1-year cancer survival statistics. This study examined the effect of health literacy on the efficacy of a gynecological cancer information leaflet. Participants (n = 451) were recruited from 17 Cancer Research UK events. Health literacy was assessed with the Newest Vital Sign test. Gynecological cancer symptom awareness and barriers to medical help seeking were assessed before and after participants read the leaflet. Symptom awareness improved, and barriers to medical help seeking were reduced (ps < .001). Symptom awareness was lower in individuals in lower health literacy groups, both at baseline and at follow-up (p < .05, p < .001, respectively), but there were no significant differences in barriers to medical help seeking at either time point (p > .05). As predicted, individuals with lower health literacy benefited less after exposure to the leaflet (ps < .01 for interactions). Despite careful consideration of information design principles in the development of the leaflet, more intensive efforts may be required to ensure that inequalities are not exacerbated by reliance on print-based public health interventions.
