Comparison of Two Pollen Counting Methods of Slides from a Hirst Type Volumetric Trap.

Two of the most frequently used methods of pollen counting on slides from Hirst type traps are evaluated in this paper: the transverse traverse method and the longitudinal traverse method. The study was carried out during June–July 1996 and 1997 on slides from a trap at Worcester, UK. Three pollen types were selected for this purpose: Poaceae, Urticaceae and Quercus. The statistical results show that the daily concentrations followed similar trends (p < 0.01, R-values between 0.78–0.96) with both methods during the two years, although the counts were slightly higher using the longitudinal traverses method. Significant differences were observed, however, when the distribution of the concentrations during 24 hour sampling periods was considered. For more detailed analysis, the daily counts obtained with both methods were correlated with the total number of pollen grains for the taxon over the whole slide, in two different situations: high and low concentrations of pollen in the atmosphere. In the case of high concentrations, the counts for all three taxa with both methods are significantly correlated with the total pollen count. In the samples with low concentrations, the Poaceae and Urticaceae counts with both methods are significantly correlated with the total counts, but none of Quercus counts are. Consideration of the results indicates that both methods give a reasonable approximation to the count derived from the slide as a whole. More studies need be done to explore the comparability of counting methods in order to work towards a Universal Methodology in Aeropalynology.

Caring for Children Dying from Cancer at Home: a Qualitative Study of the Experience of Primary Care Practitioners

Background. The rarity of childhood cancers makes providing palliative care in the community an unusual event for primary care practitioners. Providing this care requires effective interprofessional collaboration with the team that forms to provide the care often working together for the first and only time. Objective. To explore the experiences of primary care practitioners following their involvement in the palliative care of a child with cancer at home. Methods. The study design was a community-based qualitative study. The study location was the West Midlands region. Purposeful sample of GPs and community nurses involved in providing palliative care to 12 children. One-to-one in-depth interviews with 47 primary care professionals (10 GPs and 37 community nurses) and 5 facilitated case discussions were undertaken. Field notes were documented and grounded theory data analysis undertaken: chronological comparative data analysis identifying generated themes. Results. GPs had minimal input into the preceding care of children undergoing treatment for cancer but sought to re-establish their role at the child’s transition to palliative care. GPs felt they had a role to play and could add value to this phase of care, highlighted their continuing role with the child’s family and acknowledged that they had gained from the experience of contributing. However, lack of specialist knowledge and uncertainty about their role within the team made this more challenging. In contrast, community nurses were routinely involved in both active treatment and palliation care phases. There was little evidence of collaboration between the specialist and primary care professionals involved. There was considerable variation in out of hours provision across cases. Conclusions. Engaging primary care practitioners needs to be more actively anticipated and negotiated at the transition to palliation. Variation in out of hours care is another cause for concern. Enhancing inter-professional collaboration and planning during both active and palliative care phases may help. Keywords. Cancer, family medicine, palliative care, paediatric.

Providing Palliative Care for the Child with Cancer: The Experience of GPs

Background Childhood cancers are rare and general practitioners (GPs) have limited experience in caring for these children and even less in providing their palliative care. Most families prefer that their child is cared for at home in the palliative phase of their illness, with professional support from those known to them (Chambers and Oakhill 1995, Vickers and Carlisle 2000, Craft and Killen 2007). A community based qualitative study examined the experiences of ten GPs following their involvement in the care of a child with cancer receiving palliative care within the family home. Methods Data collection was through 1:1 in-depth interviews and facilitated case discussion supported by field notes and grounded theory analysis (chronological comparative data analysis identifying generated themes). Social worlds theory was used as a framework to aid examination, and facilitate critical understanding, of the experiences of the GPs. Findings This presentation focuses on five of the findings relating to the experiences of the GP; the impact of minimal contact; lack of knowledge and experience, uncertain role, out of hours service provision and the emotional toll. Findings highlighted that GPs often have to re-establish their role at the child’s transition to palliative care. Factors hindering the GP in this process include a deficit of specialist knowledge and experience of paediatric palliative care and lack of role clarity. Conclusions/points of interest Strategies for enhancing the role of the Macmillan team in supporting GPs have been identified by this study, such as enhanced collaborative working. Findings have also provided further confirmation of the substantial variation in out of hours medical palliative care provision; with evidence that some GPs work beyond their remit in providing informal out of hours care. This presentation details the findings of one aspect (the experiences of GPs) of a wider study that explored the experiences of 54 community based health professionals (GPs, community nurses and allied health professionals) who had been involved in caring for a dying with cancer receiving palliative care at home (Neilson 2009).

Improving Patients’ Experience and Outcome of Total Joint Replacement: the RESTORE Programme

BACKGROUND: Total hip replacements (THRs) and total knee replacements (TKRs) are common elective procedures. In the REsearch STudies into the ORthopaedic Experience (RESTORE) programme, we explored the care and experiences of patients with osteoarthritis after being listed for THR and TKR up to the time when an optimal outcome should be expected. OBJECTIVE: To undertake a programme of research studies to work towards improving patient outcomes after THR and TKR. METHODS: We used methodologies appropriate to research questions: systematic reviews, qualitative studies, randomised controlled trials (RCTs), feasibility studies, cohort studies and a survey. Research was supported by patient and public involvement. RESULTS: Systematic review of longitudinal studies showed that moderate to severe long-term pain affects about 7–23% of patients after THR and 10–34% after TKR. In our cohort study, 10% of patients with hip replacement and 30% with knee replacement showed no clinically or statistically significant functional improvement. In our review of pain assessment few research studies used measures to capture the incidence, character and impact of long-term pain. Qualitative studies highlighted the importance of support by health and social professionals for patients at different stages of the joint replacement pathway. Our review of longitudinal studies suggested that patients with poorer psychological health, physical function or pain before surgery had poorer long-term outcomes and may benefit from pre-surgical interventions. However, uptake of a pre-operative pain management intervention was low. Although evidence relating to patient outcomes was limited, comorbidities are common and may lead to an increased risk of adverse events, suggesting the possible value of optimising pre-operative management. The evidence base on clinical effectiveness of pre-surgical interventions, occupational therapy and physiotherapy-based rehabilitation relied on small RCTs but suggested short-term benefit. Our feasibility studies showed that definitive trials of occupational therapy before surgery and post-discharge group-based physiotherapy exercise are feasible and acceptable to patients. Randomised trial results and systematic review suggest that patients with THR should receive local anaesthetic infiltration for the management of long-term pain, but in patients receiving TKR it may not provide additional benefit to femoral nerve block. From a NHS and Personal Social Services perspective, local anaesthetic infiltration was a cost-effective treatment in primary THR. In qualitative interviews, patients and health-care professionals recognised the importance of participating in the RCTs. To support future interventions and their evaluation, we conducted a study comparing outcome measures and analysed the RCTs as cohort studies. Analyses highlighted the importance of different methods in treating and assessing hip and knee osteoarthritis. There was an inverse association between radiographic severity of osteoarthritis and pain and function in patients waiting for TKR but no association in THR. Different pain characteristics predicted long-term pain in THR and TKR. Outcomes after joint replacement should be assessed with a patient-reported outcome and a functional test. CONCLUSIONS: The RESTORE programme provides important information to guide the development of interventions to improve long-term outcomes for patients with osteoarthritis receiving THR and TKR. Issues relating to their evaluation and the assessment of patient outcomes are highlighted. Potential interventions at key times in the patient pathway were identified and deserve further study, ultimately in the context of a complex intervention.

Growing Well-beings: the Positive Experience of Care Farms

Objectives: Care farms enable people who are in some way vulnerable to engage with agricultural places and farming activities. This study investigates how this impacts on the health and well-being of service users and explores associated processes and outcomes. Design: A mixed methods design was adopted that allowed for the integration of quantitative measurements of change with qualitative descriptions of this change. A pragmatic approach provided sufficient flexibility to support the investigation of complex contexts. Methods: A total of 216 service users completed an initial questionnaire, and 137 (63%) of this number provided comparative data in a follow-up questionnaire. Questionnaires contained multiple choice and open-ended questions alongside standardized health and well-being measures requiring Likert-format responses. Semi-structured interviews with 33 service users allowed personal experiences to be detailed. Results: Statistical analysis of well-being measure scores identified significant positive relationships with the length of time people had been attending the care farm. Questionnaire and interview data presented health benefits as being enabled by the farm environment, the positive experience as supporting personal development, and associated social interactions as becoming increasingly influential as time progressed. Conclusions: The health and well-being outcomes that result from participating at a care farm influence multiple elements of the human condition and apply amongst vulnerable people with a wide range of personal needs. Care farms have access to a potentially unique range of resources that can support many service users in becoming happier and healthier individuals.
