Cancers (Basel) 2023; 15:591. [PMID: 36765547 PMCID: PMC9913127 DOI: 10.3390/cancers15030591] [Citation(s) in RCA: 74] [Impact Index Per Article: 74.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/13/2023] [Accepted: 01/14/2023] [Indexed: 01/20/2023] Open
Abstract
Experiencing pain and insufficient relief can be devastating and negatively affect a patient's quality of life. Developments in oncology such as new treatments and adjusted pain management guidelines may have influenced the prevalence of cancer pain and severity in patients. This review aims to provide an overview of the prevalence and severity of pain in cancer patients in the 2014-2021 literature period. A systematic literature search was performed using the databases PubMed, Embase, CINAHL, and Cochrane. Titles and abstracts were screened, and full texts were evaluated and assessed on methodological quality. A meta-analysis was performed on the pooled prevalence and severity rates. A meta-regression analysis was used to explore differences between treatment groups. We identified 10,637 studies, of which 444 studies were included. The overall prevalence of pain was 44.5%. Moderate to severe pain was experienced by 30.6% of the patients, a lower proportion compared to previous research. Pain experienced by cancer survivors was significantly lower compared to most treatment groups. Our results imply that both the prevalence of pain and pain severity declined in the past decade. Increased attention to the assessment and management of pain might have fostered the decline in the prevalence and severity of pain.

Abstract
OBJECTIVE Parkinson's disease is a progressive, life-limiting disease, which benefits from structured palliative care. Systematic recognition and triage of needs helps facilitate care, allows focused referral to specialist palliative care and aids sustainability of services. Existing palliative care tools for Parkinson's are patient/caregiver completed and focus on quantification rather than identification of the need. The Needs Assessment Tool: Progressive Disease in Cancer was designed for rapid identification of unmet needs in cancer. We describe adaptation and psychometric testing of the tool for Parkinson's disease (NAT:Parkinson's disease). METHODS Set in secondary care, Parkinson's disease outpatient clinics in the UK, this study included people with Parkinson's, age >18, including all disease stages. People with atypical Parkinsonian syndromes were excluded. Adaptation was made using systematic review and focus groups. Construct validity was tested in 50 consecutive patients against established patient and caregiver measures, analysed with Kendall's Tau B. Inter-rater reliability, using video consultations, were calculated in broad range of clinicians involved in Parkinson's disease care using a weighted kappa; 0-0.2=slight, 0.21-0.40=fair, 0.41-0.60=moderate, 0.61-0.80=substantial and p<0.05 indicative of statistically significant agreement. RESULTS Validity was substantial for two, moderate for five and fair for four constructs. Inter-rater reliability was substantial for one, moderate for three and fair for six constructs. Two constructs failing to demonstrate fair reliability did show very high percentage agreement. CONCLUSION Findings support the suitability of the NAT:Parkinson's disease for everyday clinical use in the identification and triage of unmet palliative need for people with Parkinson's disease.

Abstract
INTRODUCTION Unmet needs in patients with cancer and their carers are common but poorly identified and addressed. The Needs Assessment Tool-Cancer (NAT-C) is a structured consultation guide to identify and triage patient and carer unmet needs. The NAT-C is validated, but its effectiveness in reducing unmet patient and carer needs in primary care is unknown. METHODS AND ANALYSIS Cluster randomised controlled trial with internal pilot and embedded process evaluation to test the clinical and cost effectiveness of the NAT-C in primary care for people with active cancer in reducing unmet patient and carer need, compared with usual care. We will recruit 1080 patients with active cancer (and carers if relevant) from 54 general practices in England.Participating practices will be randomised 1:1 to either deliver an NAT-guided clinical consultation plus usual care or to usual care alone. Consenting participants with active cancer and their carers (if nominated) will be asked to complete study questionnaires at baseline, 1 and 3 months for all, 6 months except for those recruited outside of the last 3 months of recruitment, and attend an NAT-C appointment if allocated to an intervention practice. An internal pilot will assess: site and participant recruitment, intervention uptake and follow-up rates. The primary outcome, the proportion of patients with an unmet need on the Supportive Care Needs Survey Short Form 34 at 3 months postregistration, will be analysed using a multilevel logistic regression. Mixed-methods process evaluation informed by Normalisation Process Theory will use quantitative survey and interview data from clinicians and key stakeholders in cancer care to develop an implementation strategy for nationwide rollout of the NAT-C if the intervention is cost-effective. ETHICS AND DISSEMINATION Ethical approval from London-Surrey REC (20/LO/0312). Results will be peer-reviewed, published and made available to research participants. TRIAL REGISTRATION NUMBER ISRCTN15497400.

Abstract
CONTEXT People with advanced heart failure have supportive and palliative needs requiring systematic assessment. OBJECTIVES We aimed to assess the validity of the Needs Assessment Tool: Progressive Disease - Heart Failure (NAT:PD-HF). METHODS Secondary analysis of routinely collected patient data from a specialist palliative care-heart disease service improvement project. NAT:PD-HF, the Integrated Palliative care Outcome Scale (IPOS), and patient and/or carer-report data were collected. Concurrent validity between NAT:PD-HF items and comparison measures (Kendall's tau; kappa); construct validity via known-group comparisons; predictive utility of NAT:PD-HF for survival (multivariable Cox hazard regression model). RESULTS Data from 88 patients (50% men; mean age 85; median survival 205 days; 64% left ventricular systolic dysfunction) were analyzed. Prevalence- and bias-adjusted kappa values indicated moderate agreement for physical symptom needs (k: 0.33 for patients, 0.42 for carers). Substantial agreement was observed for patient and/or carer psychological symptoms, and information needs (k ≥ 0.6). NAT:PD-HF distinguished between patients with different survival, comorbidities, functional scores, and palliative Phase of Illness with moderate to high effect sizes. NAT did not predict survival when adjusted for mortality risk score and functional status (2+ needs HR: 1.52, 95% CI: 1.01-1.74). CONCLUSION The NAT:PD-HF is a valid tool for clinician assessment of physical, psychosocial, and information patient and/or carer needs.

Abstract
PURPOSE This study aimed to develop and test the psychometric properties of a Professional Nursing Support Scale for patients with cancer in mainland China. METHODS The study was conducted in two phases from January 2017 to January 2020. Phase I involved item generation and developing a preliminary version of Professional Nursing Support Scale through literature review, qualitative interviews, content validity evaluation and a pilot study. Phase II involved psychometric properties testing of the Professional Nursing Support Scale in 700 patients with cancer recruited from four public hospitals in Anhui Province, China. RESULTS A 49-item Professional Nursing Support Scale was finally developed. Exploratory factor analysis showed a four-factor structure of the 49-item Professional Nursing Support Scale, accounting for 56.95% of variance. Cronbach's α ranged from 0.91 to 0.94 for the four subscales. Confirmatory factor analysis further confirmed the best model fit of four-factor structure of the Professional Nursing Support Scale. The Professional Nursing Support Scale also showed an acceptable concurrent validity with Supportive Care Needs Scale short form 34 (r = 0.75, p < 0.001) and Psychological Distress Thermometer (r = 0.39, p < 0.001). CONCLUSIONS The Professional Nursing Support Scale is a reliable and valid instrument to assess perceived needs of professional nursing support and support acquisition in relation to the care in Chinese patients with cancer.

A cluster randomised trial of a Needs Assessment Tool for adult Cancer patients and their carers (NAT-C) in primary care: A feasibility study. PLoS One 2021; 16:e0245647. [PMID: 33507949 PMCID: PMC7842977 DOI: 10.1371/journal.pone.0245647] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 01/05/2021] [Indexed: 01/03/2023] Open
Abstract
Background People with cancer often have unidentified symptoms and social care needs. The Needs Assessment Tool-Cancer (NAT-C) is a validated, structured method of assessing patient/carer concerns and prompting action, to address unmet need. Aims Assess feasibility and acceptability of a definitive two-armed cluster randomised trial of NAT-C in primary care by evaluating: recruitment of GP practices, patients and carers; most effective approach of ensuring NAT-C appointments, acceptability of study measures and follow-up. Methods Non-blinded, feasibility study in four General Practices, with cluster randomisation to method of NAT-C appointment delivery, and process evaluation. Adults with active cancer were invited to participate with or without carer. Practices cluster randomised (1:1) to Arm I: promotion and use of NAT-C with a NAT-C trained clinician or Arm II: clinician of choice irrespective of training status. Participants completed study questionnaires at: baseline, 1, 3 and 6 months. Patients booked a 20 minute needs-assessment appointment post-baseline. Patients, carers and GP practice staff views regarding the study sought through interviews/focus groups. Quantitative data were analysed descriptively. Qualitative data were analysed thematically, informed by Normalisation Process Theory. Progression to a definitive trial was assessed against feasibility outcomes, relating to: recruitment rate, uptake and delivery of the NAT-C, data collection and quality. Results Five GP practices approached, four recruited and trained to use the NAT-C. Forty-seven participants and 17 carers recruited. At baseline, 34/47 (72%) participants reported at least one moderate-severe unmet need, confirming study rationale. 32/47 (68%) participants received a NAT-C-guided consultation, 19 of which on Arm I. Study attrition at one month (n = 44 (94%), n = 16 (94%)), three months (n = 38 (81%), n = 14 (82%)) and six months (n = 32 (68%), n = 10 (59%)). Fifteen patient interviews conducted across the whole study and one focus group at each GP practice. Participants supported a definitive study and found measures acceptable. Conclusion The feasibility trial indicated that recruitment rate, intervention uptake and data collection were appropriate, with refinements, for a definitive multi-centre cluster randomised controlled trial. Feasibility outcomes informed the design of a 2-armed cluster randomised controlled trial to test the effectiveness and cost-effectiveness of the NAT-C compared with usual care.

Abstract
Patient-defined factors that are important at the end of life include being physically independent for as long as possible, good symptom control, and spending quality time with friends and family. Hospice care adds to the quality of care and these patient-centered priorities for people with cancer and their families in the last weeks and days of life. Evidence from large observational studies demonstrate that hospice care can improve outcomes directly and support better and more appropriate health care use for people in the last stages of cancer. Team-based community hospice care has measurable benefits for patients, their family caregivers, and health services. In addition to improved symptom control for patients and a greater likelihood of time spent at home, caregiver outcomes are better when hospice care is accessed: informational needs are better met, and caregivers have an improved ability to move on with life after the patient’s death compared with people who did not have access to these services. Hospice care continues to evolve as its reach expands and the needs of patients continue to broaden. This is reflected in the transition from hospice being based on excellence in nursing to teams with a broad range of health professionals to meet the complex and changing needs of patients and their families. Additional integration of cancer services with hospice care will help to provide more seamless care for patients and supporting family caregivers during their caregiving and after the death of the patient.

Abstract
Objective: In cancer care management, patients or their family are usually responsible for continuing health care. Achieving this goal requires identification of their self-care needs. The purpose of this study is to explore the perception of self-care needs of adolescent cancer survivors. Methods: This study was conducted by the qualitative content analysis method. Participants were 19 adolescent childhood cancer survivors and six parents, nurses, physicians, and charity institution staff from children teaching hospitals in Iran. Participants were selected through purposeful sampling, and individual semistructured interviews were used for data collection. Graneheim and Lundman stages of content analysis were employed for data analysis. Data were managed with the MAXQDA10 software. Results: Content analysis revealed nine subcategories as follows: (1) nutritional protection, (2) prevention from infection, (3) prevention from physical damage, (4) control over cancer recurrence, (5) informational needs, (6) pain management, (7) releasing positive thoughts, (8) continuing routine life, and (9) family protection. The first six subthemes were related to protection against physical distress, and the final three ones were related to protection against psychological distress. These two categories form one theme: “protective self-care need” as an essential self-care need in adolescent cancer survivors. Conclusions: Pediatric and school health nurses can prepare strategies to meet these needs by providing effective informational and psychosocial supports, and healthcare providers are able to check periodically the status of survivors care to provide second or third level of care to prevent escalation and incidence of the adverse outcomes of the disease.

Abstract
Supportive care is an important strategy that can help cancer survivors manage changes and problems during their follow-up care. Identifying patients' care needs is one of the primary steps of the nursing process to plan effective nursing interventions. The aim of this study was to explore adolescent cancer survivors' supportive care needs. Purposeful sampling was adopted to select 49 participants from hospitals to participate in face-to-face, semistructured interviews. The qualitative content analysis method was conducted for data analysis. Ten subcategories and four main categories - empathetic care, information about survival period, instrumental support, and cooperation in care - were extracted from the data. These four categories formed a major theme, "supportive care", as the primary healthcare need. This study highlights that supportive care should be developed collaboratively by family and healthcare providers to meet the needs of adolescent cancer survivors. Survivors' strengths and limitations should be identified, and then supportive care can be provided, such as giving appropriate information, enabling survivors to access supportive networks, and improving survivors' confidence and autonomy with their self-management.
