    Prevalence of malnutrition and nutrition-related complications in patients with gastroenteropancreatic neuroendocrine tumours
    Laing, E ; Gough, K ; Krishnasamy, M ; Michael, M ; Kiss, N (WILEY, 2022-06)
    Cross-sectional studies report that up to 25% of people with gastroenteropancreatic neuroendocrine tumours (GEP NET) are malnourished. However, the changes in nutritional status and dietary intake over time are unknown. The present study aimed to comprehensively describe the impact of a GEP NET on nutritional status and quality of life (QOL). Patients diagnosed with a GEP NET were recruited to this prospective longitudinal study on initial attendance to the NET Unit at two tertiary hospitals in Melbourne (VIC, Australia). Patient self-reported QOL measures (European Organisation for Research and Treatment Cancer QLC-C30 and QLC-GINET21) and nutritional outcomes (nutritional status, weight change, fat-free mass [FFM], dietary change, dietitian contact) were collected bi-monthly for six months. Sixty-one patients were recruited (66% male) with a mean ± SD age of 62 ± 12 years, predominantly diagnosed with small intestinal NET and Grade 1/2 disease. Commonly reported symptoms were fatigue (79%), abdominal discomfort (75%) and pain (68%). More patients were malnourished at baseline than at 6 months (29% vs. 13%). Over this 6 months, 48% lost weight, 20% lost ≥ 5% of their body weight, and 62% lost FFM with an average FFM loss of 2.8 kg (95% confidence interval = 2.0, 3.6), consistent with altered body composition. Dietary change was reported by 56% at baseline and 53% at six months, but only 21% consulted a dietitian at baseline and 18% at 6 months. Clinically significant loss of weight and FFM affected many patients with a GEP NET; however, few patients were referred to/or received a consultation with a dietitian. Valid screening practices are needed to identify weight loss and nutrition issues in GEP NET patients, and to facilitate referral to dietitian services.

    Social return on investment economic evaluation of supportive care for lung cancer patients in acute care settings in Australia
    Hyatt, A ; Chung, H ; Aston, R ; Gough, K ; Krishnasamy, M (BMC, 2022-11-23)
    BACKGROUND: Unmanaged consequences of cancer and its treatment are high among patients with lung cancer and their informal carers, resulting in avoidable healthcare use and financial burden. Provision of cancer supportive care addressing the impacts of cancer and its treatment has demonstrated efficacy in mitigating these consequences; however, globally, there is a lack of investment in these services. Paucity of robust economic evidence regarding benefit of cancer supportive care has limited policy impact and allocation of resources. This study therefore utilised a Social Return on Investment (SROI) methodology to conduct a forecast evaluation of lung cancer supportive care services, to ascertain potential social value and return on investment. METHODS: An SROI economic evaluation model was developed using qualitative stakeholder consultations synthesised with published evidence to develop the inputs, outcomes and financial value associated with the delivery of a hypothetical model of quality lung cancer supportive care services over a one and five year period. SROI ratios were generated to determine the social value and cost savings associated per every $1AUD invested in cancer supportive care for both the healthcare system and patients. Deadweight, drop off and attribution were calculated, and sensitivity analysis was performed to confirm the stability of the model. RESULTS: The value generated from modelled supportive care service investments in a one-year period resulted in an SROI ratio of 1:9; that is, for every dollar invested in supportive care, AUD$9.00 social return is obtained when savings to the healthcare system and benefits to the patients are combined. At five-years, these same investments resulted in greater cumulative value generated for both the patient and the healthcare system, with a SROI ratio of 1:11. CONCLUSION: Our study provides strong evidence for policy makers, clinicians and consumers to advocate for further investment in cancer supportive care, as demonstrated cost savings could be achieved through implementation of the proposed supportive care service model, with these accruing over a five-year period. The SROI model provides a comprehensive framework detailing supportive care services and the health workforce necessary to achieve value-based outcomes for patients and the healthcare system.

    Cancer-related cognitive impairment in patients with newly diagnosed aggressive lymphoma undergoing standard chemotherapy: a longitudinal feasibility study
    Gates, P ; Krishnasamy, M ; Wilson, C ; Hawkes, EA ; Dore, V ; Perchyonok, Y ; Rowe, CC ; Walker, AK ; Vardy, JL ; de Ruiter, MB ; Cushion, T ; Dhillon, HM ; Gough, K (SPRINGER, 2022-09)
    PURPOSE: Cancer-related cognitive impairment (CRCI) is a recognised adverse consequence of cancer and its treatment. This study assessed the feasibility of collecting longitudinal data on cognition in patients with newly diagnosed, aggressive lymphoma undergoing standard therapy with curative intent via self-report, neuropsychological assessment, peripheral markers of inflammation, and neuroimaging. An exploration and description of patterns of cancer-related cognitive impairment over the course of treatment and recovery was also undertaken and will be reported separately. METHODS: Eligible participants completed repeated measures of cognition including self-report and neuropsychological assessment, and correlates of cognition including blood cell-based inflammatory markers, and neuroimaging at three pre-specified timepoints, time 1 (T1) - pre-treatment (treatment naïve), time 2 (T2) - mid-treatment, and time 3 (T3) - 6 to 8 weeks post-completion of treatment. RESULTS: 30/33 eligible patients (91%, 95% CI: 76%, 97%) were recruited over 10 months. The recruitment rate was 3 patients/month (95% CI: 2.0, 4.3 patients/month). Reasons for declining included feeling overwhelmed and rapid treatment commencement. Mean age was 57 years (SD = 17 years) and 16/30 (53%) were male. Most patients (20/30, 67%) had diffuse large B cell lymphoma or Hodgkin lymphoma (4/30, 13%). The neuroimaging sub-study was optional, 11/30 participants (37%) were eligible to take part, and all agreed. The remaining 19 participants were ineligible as their diagnostic PET/CT scan was completed prior. Retention and compliance with all assessments were 89 to 100% at all timepoints. Only one participant was withdrawn due to disease progression. CONCLUSIONS: Findings from this study including excellent recruitment, retention, and compliance rates demonstrate it is feasible to longitudinally assess cognition in people with newly diagnosed aggressive lymphoma during their initial treatment and recovery to inform the development of future research to improve patient experiences and cognitive outcomes.

    Pre-diagnostic routes to colorectal cancer in Central New Zealand: factors that lead to emergency presentation and longer diagnostic intervals at primary and secondary level care
    Warren, M ; Emery, J ; Krishnasamy, M ; O'Donnell, A ; Gough, K (CSIRO PUBLISHING, 2022)
    Introduction Although international large-scale studies have investigated routes to diagnosis for colorectal cancer, there is limited information on how New Zealanders seek help for bowel symptoms across different pre-diagnostic routes. Aim To better understand pre-diagnostic routes for colorectal cancer, including the characteristics of patients and key events associated with each route. Methods This study was a retrospective audit of hospital administrative and medical records for 120 patients with a confirmed diagnosis of colorectal cancer between 2016 and 2017. All patients were receiving care at one of two hospitals in central New Zealand; one urban and one rural. Extracted data were used to: categorise pre-diagnostic routes for colorectal cancer; describe the characteristics of people who presented by each route; and compare key events in the diagnostic and treatment intervals for people who presented by each route. Results Six routes to the diagnosis of colorectal cancer were identified. The three main routes included: routine general practitioner (GP) referral (28%, 95% CI: 21-37%), emergency presentation (27%, 95% CI: 20-35%), and other outpatient services (26%, 95% CI: 19-34%). Patients diagnosed by routine GP referral had the longest time to diagnosis, impacting on timeliness of treatment. Discussion This study has generated detailed insights about pre-diagnostic routes for colorectal cancer in New Zealand and shown consistency with findings from previously published international research. The granular findings can now inform areas for person- and system-level interventions that, in turn, could be tested in future studies to minimise emergency department and late presentations for colorectal cancer treatment in New Zealand.

    Methodological approaches to measuring the incidence of unplanned emergency department presentations by cancer patients receiving systemic anti-cancer therapy: a systematic review
    Dufton, PH ; Gerdtz, MF ; Jarden, R ; Krishnasamy, M (BMC, 2022-03-21)
    BACKGROUND: The need to mitigate the volume of unplanned emergency department (ED) presentations is a priority for health systems globally. Current evidence on the incidence and risk factors associated with unplanned ED presentations is unclear because of substantial heterogeneity in methods reporting on this issue. The aim of this review was to examine the methodological approaches to measure the incidence of unplanned ED presentations by patients receiving systemic anti-cancer therapy in order to determine the strength of evidence and to inform future research. METHODS: An electronic search of Medline, Embase, CINAHL, and Cochrane was undertaken. Papers published in English language between 2000 and 2019, and papers that included patients receiving systemic anti-cancer therapy as the denominator during the study period were included. Studies were eligible if they were analytical observational studies. Data relating to the methods used to measure the incidence of ED presentations by patients receiving systemic anti-cancer therapy were extracted and assessed for methodological rigor. Findings are reported in accordance with the Synthesis Without Meta-Analysis (SWiM) guideline. RESULTS: Twenty-one articles met the inclusion criteria: 20 cohort studies, and one cross-sectional study. Overall risk of bias was moderate. There was substantial methodological and clinical heterogeneity in the papers included. Methodological rigor varied based on the description of methods such as the period of observation, loss to follow-up, reason for ED presentation and statistical methods to control for time varying events and potential confounders. CONCLUSIONS: There is considerable diversity in the population and methods used in studies that measure the incidence of unplanned ED presentations by patients receiving systemic anti-cancer therapy. Recommendations to support the development of robust evidence include enrolling participants at diagnosis or initiation of treatment, providing adequate description of regular care to support patients who experience toxicities, reporting reasons for and characteristics of participants who are lost to follow-up throughout the study period, clearly defining the outcome including the observation and follow-up period, and reporting crude numbers of ED presentations and the number of at-risk days to account for variation in the length of treatment protocols.

    Interventions to improve patient understanding of cancer clinical trial participation: a systematic review
    Kao, CY ; Aranda, S ; Krishnasamy, M ; Hamilton, B (WILEY, 2017-03)
    Patient misunderstanding of cancer clinical trial participation is identified as a critical issue and researchers have developed and tested a variety of interventions to improve patient understanding. This systematic review identified nine papers published between 2000 and 2013, to evaluate the effects of interventions to improve patient understanding of cancer clinical trial participation. Types of interventions included audio-visual information, revised written information and a communication training workshop. Interventions were conducted alone or in combination with other forms of information provision. The nine papers, all with methodological limitations, reported mixed effects on a small range of outcomes regarding improved patient understanding of cancer clinical trial participation. The methodological limitations included: (1) the intervention development process was poorly described; (2) only a small element of the communication process was addressed; (3) studies lacked evidence regarding what information is essential and critical to enable informed consent; (4) studies lacked reliable and valid outcome measures to show that patients are sufficiently informed to provide consent; and (5) the intervention development process lacked a theoretical framework. Future research needs to consider these factors when developing interventions to improve communication and patient understanding during the informed consent process.

    Barriers and facilitators to the implementation of audio-recordings and question prompt lists in cancer care consultations: A qualitative study
    Moloczij, N ; Krishnasamy, M ; Butow, P ; Hack, TF ; Stafford, L ; Jefford, M ; Schofield, P (ELSEVIER IRELAND LTD, 2017-06)
    OBJECTIVE: Question prompt lists (QPLs) and consultation audio-recordings (CARs) are two communication strategies that can assist cancer patients in understanding and recalling information. We aimed to explore clinician and organisational barriers and facilitators to implementing QPLs and CARs into usual care. METHODS: Semi-structured interviews with twenty clinicians and senior hospital administrators, recruited from four hospitals. Interviews were recorded, transcribed verbatim and thematic descriptive analysis was utilised. RESULTS: CARs and QPLs are to some degree already being initiated by patients but not embedded in usual care. Systematic use should be driven by patient preference. Successful implementation will depend on minimal burden to clinical environments and feedback about patient use. CARs concerns included: medico-legal issues, ability of the CAR to be shared beyond the consultation, and recording and storage logistics within existing medical record systems. QPLs issues included: applicability of the QPLs, ensuring patients who might benefit from QPL's are able to access them, and limited use when there are other existing communication strategies. CONCLUSIONS: While CARs and QPLs are beneficial for patients, there are important individual, system and medico-legal considerations regarding usual care. PRACTICE IMPLICATIONS: Identifying and addressing practical implications of CARs and QPLs prior to clinical implementation is essential.

    Self-guided interventions for managing psychological distress in people with cancer - A systematic review
    Ugalde, A ; Haynes, K ; Boltong, A ; White, V ; Krishnasamy, M ; Schofield, P ; Aranda, S ; Livingston, P (ELSEVIER IRELAND LTD, 2017-05)
    OBJECTIVE: People with cancer can experience psychological distress but do not always desire, or engage with, professional support to assist with managing distress. Interventions that are self-directed or guided by patients may hold promise as they allow patients to engage with interventions as they need. The objective of this review is to describe and appraise the evidence for effectiveness of self-guided interventions that aim to manage psychological distress in people with cancer. METHODS: A systematic search of Medline, PsychInfo and CINAHL identified 15 relevant papers, reporting on 14 studies. RESULTS: Of the interventions, three studies comprised hard-copy workbooks, six studies used resource packs, four were online resources and one was a brief multimedia resource. One study was adequately powered and demonstrated a positive effect. Almost all interventions required some level of facilitation. Distressed participants may benefit more from interventions. CONCLUSION: Self-guided interventions represent a potentially efficient way of delivering support for people affected by cancer, however evidence supporting them is lacking. PRACTICE IMPLICATIONS: There is a need to generate evidence to understand the impact of self-guided interventions for: i) the ideal delivery point in the disease trajectory, ii) patient groups, iii) intervention content and iv) type and mode of delivery.

    Exploration of motivation to participate in a study of cancer-related cognitive impairment among patients with newly diagnosed aggressive lymphoma: a qualitative sub-study
    Gates, P ; Dhillon, H ; Gough, K ; Wilson, C ; Hawkes, E ; Scudder, L ; Cushion, T ; Krishnasamy, M (SPRINGER, 2022-02)
    PURPOSE: Cancer-related cognitive impairment (CRCI) is a recognised adverse consequence of cancer and its treatment. This qualitative sub-study was undertaken as part of a larger prospective longitudinal study in which recruitment and retention were very high. The aim was to gain an understanding of participants reasons for ongoing participation, at a time of heightened stress related to a new diagnosis of aggressive lymphoma and the rapid commencement of treatment. METHODS: This qualitative descriptive sub-study included semi-structured interviews with twenty-seven participants. Interviews were recorded and transcribed, and a thematic descriptive approach was used to analyse the data. RESULTS: Twenty-seven interviews were completed. Four themes described participants' motivation to consent and continue with the study. These included ease of participation, personal values, self-help and valued additional support. Participants understood the requirements of the study, and data collection occurring during hospital visits was perceived to be convenient. Interviewees confirmed that the study fulfilled desire to "help others". Although testing was intense and challenging, it provided feedback on current functioning and was described by some as a "welcome distraction" and enjoyable. Finally, interaction with the study nurse was perceived as an additional beneficial oversight and support. CONCLUSION: Achieving sustained participation in a prospective study with patients undergoing treatment is facilitated where the logistical demands of data collection are minimised; a clinician from the service is included; the tasks are seen as inherently interesting; and care is taken to provide empathic support throughout.

    Identifying essential information to support patient decision-making regarding participation in cancer clinical trials: A Delphi study
    Kao, C-Y ; Aranda, S ; Krishnasamy, M ; Hamilton, B (WILEY, 2018-11)
    PURPOSES: This research set out to contribute to ongoing efforts to improve the quality of informed consent information provided to patients by specifically focusing on establishing consensus with regard to essential information to enhance the informed consent process. DESIGN AND METHODS: A Delphi consensus method was used to conduct three rounds of online surveys. Five groups of experts directly or indirectly involved in the informed consent process were invited to participate: patients, family members/friends, physicians, other health professionals and other key informants, including ethicists, contract research staff and pharmaceutical company staff. FINDINGS: Of 156 eligible participants, 101 participants (64.7%) completed all three rounds. In round 1, 994 information items were reported and generated into 74 statements. These were grouped under eight headings essential to the informed consent process. In rounds 2 and 3, the list was reduced to 15 statements representing consensus on essential information to be included in a summarised patient information document to support decision-making regarding trial participation. Risks and discomforts, participation requirements and trial governance were identified as important considerations. CONCLUSIONS: The 15 essential statements identified in this study could be used as components of a summarised information sheet given to potential cancer clinical trial participants, as an adjunct to the informed consent process. A robust evaluation of the impact of these statements on the quality of the informed consent process is needed.
