'Caring beyond capacity' during the coronavirus pandemic: resilience and family carers of people with dementia from the IDEAL cohort

Family carers of people with dementia have reported increased caring demands during the COVID-19 pandemic. The aim of this qualitative study was to explore seven family carers' accounts of dementia caregiving one year into the COVID-19 pandemic in England in relation to carer resilience. Themes described the complex challenges of caring during the pandemic, with interviewees burned out and 'caring beyond capacity' due to unmet needs within the caring role, therein highlighting the limitations of building individual resilience only. Timely practical support for carers is essential to protect their well-being and to ward against the potential consequences of carer burnout.

The precariousness of living with, and caring for people with, dementia: Insights from the IDEAL programme

This paper uses precarity as a framework to understand the vulnerabilities experienced by those living with or caring for someone living with dementia. Drawing on qualitative interview data from the Improving the Experience of Dementia and Enhancing Active Life (IDEAL) programme, we attend to our participants' reflections on how they manage the condition and the wider circumstances in which this occurs. To interrogate the utility of precarity, we focus on our participants' descriptions of needs and challenges and set these alongside both the wider contexts in which they seek or offer care (formal and informal) and the sets of values attributed to different ways of living with dementia. Building on the work of Portacolone, our analysis identified four interconnected themes: uncertainty; experiences of support and services; independence and personhood; and cumulative pressures and concerns. We develop this analysis by reviewing how our themes reflect, extend, or depart from previously identified markers of precarity and consider the specific ways in which these markers shape the lives of those living with dementia.

Navigating the coronavirus pandemic 2 years on: Experiences of people with dementia from the British IDEAL cohort

BACKGROUND AND OBJECTIVES

People with dementia have been affected in unique ways during the COVID-19 pandemic. It is not known whether the impact of the pandemic has changed with time or with the changes in social restrictions. This study explored how experiences of coping with the effects of the pandemic in the UK changed over time.

RESEARCH DESIGN AND METHODS

We conducted semi-structured interviews with people with dementia living in the community in England and Wales who had taken part in a qualitative interview at an earlier stage of the pandemic. We applied framework analysis to identify themes and compared these with interviewees' previous accounts.

FINDINGS

Nine people aged between 51 and 89 years were interviewed; four were female and five had early onset dementia. We identified three themes: 1. Navigating a changing world: Living with coronavirus; 2. A 'downward spiral': Managing advancing dementia; and 3. Availability, accessibility, and suitability of support. Findings reflect participants' ongoing caution about re-emerging from social restrictions to resume valued activities, and how this led to coping behaviours to minimise the impact on wellbeing in the absence of formal support and services.

DISCUSSION AND IMPLICATIONS

Despite easing of restrictions across the UK, the negative impact of the coronavirus pandemic on people with dementia continues. Whilst individuals and services have adapted to some of the challenges, there is now an opportunity to rebuild support networks and services to ensure people with dementia are suitably advised, supported and socially engaged to allow them to live as well as possible.

1317 A QUALITY IMPROVEMENT PROJECT AIMING TO ENHANCE THE RECOGNITION OF INPATIENT WEIGHT LOSS ON AN ELDERLY WARD

Background

Weight loss in the older adult is often multifactorial and can be associated with increased morbidity and mortality. Our quality improvement project focused on nutritional care of patients 75 years or older. This hospital has a standardised Nutrition and Hydration Policy based on NICE guidelines to prevent malnutrition in hospital inpatients including weighing patients every 72 hours, daily screening and food/hydration charts. Our project aimed to increase adherence, with a focus on increasing the percentage of patients being regularly weighed over a 6-month period to 90%.

Methods

Our stakeholder analysis highlighted the multidisciplinary nature of our project, particularly involving the healthcare assistants. The percentage of patients weighed within 72 hours was recorded weekly. The first PDSA cycle introduced the project and gained buy-in from the MDT, highlighting required weights in MDT meetings/board rounds. The second cycle included an education session for doctors. The third cycle involved a poster in each bay aiming to act as a prompt and promote patient and family involvement.

Results

Our run chart shows that following our first two PDSA cycles eight consecutive results were higher than the baseline (40% of patients weighed). Results ranged from 70-90%. Following the third intervention compliance returned to baseline but coincided with significant disruption to the ward structure and team. Our successful intervention of nutritional teaching was then repeated as a fourth PDSA cycle and the mean returned to 80%.

Conclusions

Nutritional care requires multidisciplinary involvement. The educational session had the most impact and in future could be delivered to additional MDT members. Disappointingly the poster did not stimulate patient or family participation. We would like to create an ethos on elderly wards where nutrition routinely features in ward-based comprehensive geriatric assessments. Future plans hope to further engage patients and families as visiting restrictions eased.

Effects of social restrictions on people with dementia and carers during the pre-vaccine phase of the COVID-19 pandemic: Experiences of IDEAL cohort participants

This qualitative study was designed to understand the impact of social distancing measures on people with dementia and carers living in the community in England and Wales during a period of social restrictions before the COVID-19 vaccination roll-out. We conducted 12 semi-structured interviews with people with dementia aged 50-88 years, living alone or with a partner, and 10 carers aged 61-78 years, all living with the person with dementia. Three of the interviews were with dyads. Participants were recruited during November and December 2020. We used framework analysis to identify themes and elicit suggestions for potential solutions. We identified three interrelated themes. People with dementia experienced a fear of decline in capabilities or mood and attempted to mitigate this. Carers noticed changes in the person with dementia and increased caring responsibilities, and for some, a change in the relationship. Subsequently, reduced confidence in capabilities to navigate a new and hostile environment created a cyclical dilemma of re-engaging where an inability to access usual activities made things worse. People with dementia and carers experienced neglect and being alone in their struggle, alongside feeling socially excluded during the pandemic, and there was little optimism associated with the upcoming vaccine programme. People found their own solutions to reduce the effects of isolation by keeping busy and being socially active, and practising skills deemed to help reduce the progression of dementia. This and some limited local public initiatives for the general public facilitated feelings of social inclusion. This study adds understanding to existing evidence about the longer-term experience of social isolation several months into the pandemic. It highlights the importance of health and community groups and suggests how services can find ways to support, include, and interact with people with dementia and carers during and after social restrictions.

1504 Mandatory Reflection as a Learning Tool

Introduction

Reflection has become a compulsory part of medical training and forms the basis of most trainee portfolios.

Method

We sent an electronic questionnaire to doctors from a range of specialties at various stages of training and asked how often they were involved in reflection, whether this was mandatory, and whether they found this useful.

Results

We received 608 responses, 66% from doctors in training. 90% stated that reflection was mandatory for training. 396 had a pre-set number of reflections they had to meet in a set timeframe. 26% of respondents admitted using formulaic responses in the “majority of occasions” or “always”. 27% admitted to copying and pasting from previous reflections. 20% altered their story to make it relevant to the message they wished to convey. 85% found voluntary reflection useful to some degree.

Conclusions

Although reflection plays it part as a learning aid, making this mandatory, with a set number of reflections seems to detract from its value. There is a risk that this educational tool becomes an exercise in creative writing.

Computational modelling of wounded tissue subject to negative pressure wound therapy following trans-femoral amputation

Proof-of-concept computational models were developed and applied as tools to gain insights into biomechanical interactions and variations of oxygen gradients of wounded tissue subject to negative pressure wound therapy (NPWT), following trans-femoral amputation. A macro-scale finite-element model of a lower limb was first developed based on computed tomography data, and distributions of maximum and minimum principal stress values we calculated for a region of interest (ROI). Then, the obtained results were applied iteratively as new sets of boundary conditions for a specific spatial position in a capillary sub-model. Data from coupled capillary stress and mass- diffusion sub-models were transferred to the macro-scale model to map the spatial changes of tissue oxygen gradients in the ROI. The −70 mmHg NPWT resulted in a dramatic change of a wound surface area and the greatest relative contraction was observed at −150 mmHg. Tissue lateral to the depth of the wound cavity revealed homogenous patterns of decrease in oxygenation area and the extent of such decrease was dependent on the distance from the wound surface. However, tissue lateral to the width of the wound demonstrated heterogeneous patterns of change, as evidenced by both gradual increase and decrease in the oxygenation area. The multiscale models developed in the current study showed a significant influence of NPWT on both macro-deformations and changes of tissue oxygenation. The patterns of changes depended on the depth of the tissue, the geometry of the wound, and also the location of tissue plane.

Human factors in contingency operations

The UK Defence Medical Services are currently supporting contingency operations following a period of intensive activity in relatively mature trauma systems in Iraq and Afghanistan. Among the key lessons identified, human factors or non-technical skills played an important role in the improvement of patient care. This article describes the importance of human factors on Role 2 Afloat, one of the Royal Navy's maritime contingency capabilities, and illustrates how they are vital to ensuring that correct decisions are made for patient care in a timely manner. Teamwork and communication are particularly important to ensure that limited resources such as blood products and other consumables are best used and that patients are evacuated promptly, allowing the facility to accept further casualties and therefore maintain operational capability. These ideas may be transferred to any small specialist team given a particular role to perform.

Performance characteristics of visualising the cervix in symptomatic young females: a review of primary care records in females with and without cervical cancer

BACKGROUND

The current strategy for timely detection of cervical cancer in young females centres on visualising the cervix when females present with gynaecological symptoms, but is based on expert opinion without an evidence base.

AIM

To assess visualising the cervix in primary care in young females with gynaecological symptoms.

DESIGN AND SETTING

A review of primary care records for females in England aged 20-29 years with cervical cancer (nationwide interview-based study) and in the general population (Clinical Practice Research Datalink database).

METHOD

From primary care records the proportion of females was identified with gynaecological symptoms who had documented cervical examination in the year before diagnosis (cancers) and in 1-year age bands (general population). Of these, the proportion was identified that was then referred for suspected malignancy.

RESULTS

Only 39% of young females with cervical cancer had documented examination at symptomatic presentation. Visualisation resulted in referral for suspected malignancy for 18% of those examined (95% confidence interval = 5% to 40%). Very few (<1.7%) symptomatic females in the general population had documented cervical examination. None were referred for suspected malignancy at the time.

CONCLUSION

The sensitivity of cervical examination to detect cancer is very low, highlighting the need for better triage tools for primary care. Until such tools are identified GPs should continue to consider cervical cancer when symptoms persist and the cervix is not obviously abnormal on clinical examination. Further research on additional triage tools such as cervical cytology used as a diagnostic aid is needed urgently.

For which cancers might patients benefit most from expedited symptomatic diagnosis? Construction of a ranking order by a modified Delphi technique

BACKGROUND

This study aimed to answer the question 'for which cancers, in a symptomatic patient, does expediting the diagnosis provide an improvement in mortality and/or morbidity?'

METHODS

An initial ranking was constructed from previous work identifying 'avoidable deaths' for 21 common cancers in the UK. In a two-round modified Delphi exercise, 22 experts, all experienced across multiple cancers, used an evidence pack summarising recent relevant publications and their own experience to adjust this ranking. Participants also answered on a Likert scale whether they anticipated mortality or morbidity benefits for each cancer from expedited diagnosis.

RESULTS

Substantial changes in ranking occurred in the Delphi exercise. Finally, expedited diagnosis was judged to provide the greatest mortality benefit in breast cancer, uterine cancer and melanoma, and least in brain and pancreatic cancers. Three cancers, prostate, brain and pancreas, attracted a median answer of 'disagree' to whether they expected mortality benefits from expedited diagnosis of symptomatic cancer.

CONCLUSIONS

Our results can guide future research, with emphasis given to studying interventions to improve symptomatic diagnosis of those cancers ranked highly. In contrast, research efforts for cancers with the lowest rankings could be re-directed towards alternative avenues more likely to yield benefit, such as screening or treatment.

Medium-term outcomes following limb salvage for severe open tibia fracture are similar to trans-tibial amputation

Extremity injuries define the surgical burden of recent conflicts. Current literature is inconclusive when assessing the merits of limb salvage over amputation. The aim of this study was to determine medium term functional outcomes in military casualties undergoing limb salvage for severe open tibia fractures, and compare them to equivalent outcomes for unilateral trans-tibial amputees. Cases of severe open diaphyseal tibia fractures sustained in combat between 2006 and 2010, as described in a previously published series, were contacted. Consenting individuals conducted a brief telephone interview and were asked to complete a SF-36 questionnaire. These results were compared to a similar cohort of 18 military patients who sustained a unilateral trans-tibial amputation between 2004 and 2010. Forty-nine patients with 57 severe open tibia fractures met the inclusion criteria. Telephone follow-up and SF-36 questionnaire data was available for 30 patients (61%). The median follow-up was 4 years (49 months, IQR 39-63). Ten of the 30 patients required revision surgery, three of which involved conversion from initial fixation to a circular frame for non- or mal-union. Twenty-two of the 30 patients (73%) recovered sufficiently to complete an age-standardised basic military fitness test. The median physical component score of SF-36 in the limb salvage group was 46 (IQR 35-54) which was similar to the trans-tibial amputation cohort (p=0.3057, Mann-Whitney). Similarly there was no difference in mental component scores between the limb salvage and amputation groups (p=0.1595, Mann-Whitney). There was no significant difference in the proportion of patients in either the amputation or limb salvage group reporting pain (p=0.1157, Fisher's exact test) or with respect to SF-36 physical pain scores (p=0.5258, Mann-Whitney). This study demonstrates that medium term outcomes for military patients are similar following trans-tibial amputation or limb salvage following combat trauma.

'Did not attends' in children 0-10: a scoping review

Patients who do not attend ('DNA') health appointments have been identified as a service problem incurring significant costs to the NHS. In order to explore the causes, effects and costs of child DNAs, we carried out a scoping study to map the literature and identify gaps in the research. Given the breadth of issues underpinning DNAs, a scoping study, including research studies, audits, policy documents and conference abstracts, was the most useful way to map the field. To foster public and patient participation, we sought advice from parents participating in the National Children's Bureau's Family Research Advisory Group. From a pool of 1997 items, we found few UK studies with non-attendance of 0-10 year olds as a primary focus, though many more incidentally reported DNA rates. Overall, four topics predominated: the conceptualization of DNAs; the correlates of non-attendance; initiatives to reduce non-attendance; and the relationship between non-attendance and safeguarding. The Family Research Advisory Group identified broadly similar issues, but with a stronger emphasis on communication and practical matters. While there may be circumstances where failing to attend appointments makes little or no difference to a child (or even benefits them) it is likely that there are children whose health or well-being are compromised as a result of failing to attend appointments. Both 'over' and 'under'-attendance can be a source of anxiety to health professionals. Areas where further work is needed include robust evaluation of the effectiveness, cost-effectiveness and maintenance of measures to reduce DNAs and a better understanding of the relationship of safeguarding to non-attendance.

What works in practice: user and provider perspectives on the acceptability, affordability, implementation, and impact of a family-based intervention for child overweight and obesity delivered at scale

BACKGROUND

As part of a study considering the impact of a child weight management programme when rolled out at scale following an RCT, this qualitative study focused on acceptability and implementation for providers and for families taking part.

METHODS

Participants were selected on the basis of a maximum variation sample providing a range of experiences and social contexts. Qualitative interviews were conducted with 29 professionals who commissioned or delivered the programme, and 64 individuals from 23 families in 3 English regions. Topic guides were used as a tool rather than a rule, enabling participants to construct a narrative about their experiences. Transcripts were analysed using framework analysis.

RESULTS

Practical problems such as transport, work schedules and competing demands on family time were common barriers to participation. Delivery partners often put considerable efforts into recruiting, retaining and motivating families, which increased uptake but also increased cost. Parents and providers valued skilled delivery staff. Some providers made adaptations to meet local social and cultural needs. Both providers and parents expressed concerns about long term outcomes, and how this was compromised by an obesogenic environment. Concerns about funding together with barriers to uptake and engagement could translate into barriers to commissioning. Where these barriers were not experienced, commissioners were enthusiastic about continuing the programme.

CONCLUSIONS

Most families felt that they had gained something from the programme, but few felt that it had 'worked' for them. The demands on families including time and emotional work were experienced as difficult. For commissioners, an RCT with positive results was an important driver, but family barriers, alongside concerns about recruitment and retention, a desire for local adaptability with qualified motivated staff, and funding changes discouraged some from planning to use the intervention in future.

The risk of oesophago-gastric cancer in symptomatic patients in primary care: a large case-control study using electronic records

Background:

Over 15 000 new oesophago-gastric cancers are diagnosed annually in the United Kingdom, with most being advanced disease. We identified and quantified features of this cancer in primary care.

Methods:

Case–control study using electronic primary-care records of the UK patients aged ⩾40 years was performed. Cases with primary oesophago-gastric cancer were matched to controls on age, sex and practice. Putative features of cancer were identified in the year before diagnosis. Odds ratios (ORs) were calculated for these features using conditional logistic regression, and positive predictive values (PPVs) were calculated.

Results:

A total of 7471 cases and 32 877 controls were studied. Sixteen features were independently associated with oesophago-gastric cancer (all P<0.001): dysphagia, OR 139 (95% confidence interval 112–173); reflux, 5.7 (4.8–6.8); abdominal pain, 2.6 (2.3–3.0); epigastric pain, 8.8 (7.0–11.0); dyspepsia, 6 (5.1–7.1); nausea and/or vomiting, 4.9 (4.0–6.0); constipation, 1.5 (1.2–1.7); chest pain, 1.6 (1.4–1.9); weight loss, 8.9 (7.1–11.2); thrombocytosis, 2.4 (2.0–2.9); low haemoglobin, 2.4 (2.1–2.7); low MCV, 5.2 (4.2–6.4); high inflammatory markers, 1.7 (1.4–2.0); raised hepatic enzymes, 1.3 (1.2–1.5); high white cell count, 1.4 (1.2–1.7); and high cholesterol, 0.8 (0.7–0.8). The only PPV >5% in patients ⩾55 years was for dysphagia. In patients <55 years, all PPVs were <1%.

Conclusion:

Symptoms of oesophago-gastric cancer reported in secondary care were also important in primary care. The results should inform guidance and commissioning policy for upper GI endoscopy.

Jaundice in primary care: a cohort study of adults aged >45 years using electronic medical records

BACKGROUND

Jaundice is a rare but important symptom of malignant and benign conditions. When patients present in primary care, understanding the relative likelihood of different disease processes can help GPs to investigate and refer patients appropriately.

OBJECTIVE

To identify and quantify the various causes of jaundice in adults presenting in primary care.

DESIGN

Historical cohort study using electronic primary care records.

SETTING

UK General Practice Research Database.

METHODS

Participants (186 814 men and women) aged >45 years with clinical events recorded in primary care records between 1 January 2005 and 31 December 2007. Data were searched for episodes of jaundice and explanatory diagnoses identified within the subsequent 12 months. If no diagnosis was found, the patient's preceding medical record was searched for relevant chronic diseases.

RESULTS

From the full cohort, 277 patients had at least one record of jaundice between 1 January 2005 and 31 December 2006. Ninety-two (33%) were found to have bile duct stones; 74 (27%) had an explanatory cancer [pancreatic cancer 34 (12%), cholangiocarcinoma 13 (5%) and other diagnosed primary malignancy 27 (10%)]. Liver disease attributed to excess alcohol explained 26 (9%) and other diagnoses were identified in 24 (9%). Sixty-one (22%) had no diagnosis related to jaundice recorded.

CONCLUSION

Although the most common cause of jaundice is bile duct stones, cancers are present in over a quarter of patients with jaundice in this study, demonstrating the importance of urgent investigation into the underlying cause.

Gynaecological symptoms reported by young women: examining the potential for earlier diagnosis of cervical cancer

BACKGROUND

Cervical cancer occurs at a younger age than most adult cancers. A pre-malignant stage can be identified at screening and treated. Screening begins at the age of 25 years in England, so in women younger than this, and in those who decline screening, cervical cancer can only be identified with symptoms. Aim. To identify the frequency of attendance for gynaecological conditions by young English women.

DESIGN

Historical cohort study using electronic primary care records.

METHODS

A cohort of English women aged 15-29 years was prepared from the General Practice Research Database. All gynaecological consultations were identified and collated. Frequencies of gynaecological consultation were analysed in three age bands: 15-19, 20-24 and 25-29 years and by calendar year.

RESULTS

The number of women available for study for each year ranged from 32 968 to 45 807. The percentage of women having any gynaecological consultation increased from 17.7% to 33.3% over the 7 years. If contraception is excluded, the percentages are 11.3% in 2003, rising to 20.1% in 2009. The rise in consultations occurred in all age bands and across most symptom categories. Post-coital bleeding and inter-menstrual bleeding-the two classic presentations of cervical cancer-were reported by 0.5% and 1.6% of women in 2009.

CONCLUSIONS

Gynaecological complaints are frequent in primary care, though the symptoms of possible cervical cancer only represent a small minority of the total. Although the chance of cancer in young women with abnormal vaginal bleeding is very small, visualization of the cervix is appropriate.

No one listens to me, nobody believes me: self management and the experience of living with encephalitis

Over the past twenty years, there has been considerable interest in individuals' experience of chronic illness. In addition to the more established concerns of medical sociology, recent policy reflects an interest in how individuals manage their condition. Using material from qualitative interviews with 23 individuals carried out in the United Kingdom, this paper examines a person's experience following encephalitis, as a way of exploring the potential value of current policy initiatives associated with self-management. Our findings suggest that individuals' illness experiences become embedded in conditional acceptance derived from and sustained through their social relationships. This raises a fundamental policy tension: is the purpose of current self-management strategies to help individuals cope better with illness or with the context in which their illness experience is realised? We conclude that policy needs to question how it 'imagines' long-standing conditions, without recourse to generalised notions of coping and adjustment. This, in turn, means adapting a less instrumental and more contextualised approach to self-management.

Pathways to the diagnosis of ovarian cancer in the UK: a cohort study in primary care

OBJECTIVE

To identify the routes patients with ovarian cancer take between first symptom presentation and diagnosis.

DESIGN

Cohort study.

SETTING

The study took place in 39 general practices in Devon, UK.

POPULATION

All ovarian cancer patients identified in the practices, with a diagnosis between 2000 and 2007 inclusive.

METHODS

All patients had their cancer symptoms, referrals, and diagnoses identified and dated using their doctors' records.

MAIN OUTCOME MEASURES

Numbers of patients taking specific routes to diagnosis, together with the time taken to diagnosis.

RESULTS

Three main routes to diagnosis emerged. The first was the expected route of outpatient referral: 195 (92% of the total) had at least one of the seven ovarian cancer symptoms or an abdominal mass. A total of 123 (58%) were referred to a specialist, although only 65 (31%) were referred to a gynaecologist. Thirty-five (17%) were initially investigated within primary care by ultrasound scanning, and a further 35 (17%) were admitted as emergencies. The interval from first symptom to referral was similar across the different pathways, with a median (interquartile range) time between the first symptom presenting to primary care and first investigation or referral being 2.5 (0, 27.5) days. The median interval from first symptom reported in primary care to diagnosis was 74.5 (32, 159) days.

CONCLUSIONS

Only a minority of ovarian cancer patients follow the expected route to diagnosis, of urgent referral to a gynaecologist. In most women, GPs rapidly identified the need to investigate. Avoidable delays generally occurred after the decision to investigate was made.

What happens to new-onset headache in children that present to primary care? A case-cohort study using electronic primary care records

The aim was to describe the consulting behaviour and clinical outcomes of children presenting with headache in primary care. This was a historical cohort study using data from the UK General Practitioner Research Database. Cases were children aged 5-17 years who presented to primary care with primary headache (migraine, tension-type headache, cluster headache) or undifferentiated headache (no further descriptor). Controls were age, sex and practice matched. Their records were examined for consultations, referrals, relevant treatments and specific diseases in the subsequent year. Children with headache (n = 48 575) were identified and matched to controls. At presentation, 9321 (19.2%) of headaches were labelled primary, 549 (1.1%) secondary and 38 705 (79.7%) received no formal diagnosis. Of the latter group, 2084 (5.4%) received a primary headache diagnosis in the subsequent year. Following a diagnosis of migraine, 258 (3.5%) had received a triptan and 1598 (21%) were using propranolol or pizotifen. Total consultations were higher in cases than in controls in the year before the headache: cases ages 5-8 years, mean (s.d.) 5.0 (4.0) consultations; controls 4.0 (3.5) consultations. In 1 year controls had 43 430 consultations, of which 256 (0.6%) were for headache, of whom 64 (25%) were referred to secondary care. Headache was a risk factor for benign and malignant tumours, cerebrovascular disease, primary disorders of raised intracranial pressure and depression. This risk was reduced if a diagnosis of a primary headache disorder could be made. Although there is an increased likelihood of a serious pathology with headache presentations, the risk is small particularly if a diagnosis of a primary headache is made. General practitioners are likely to be underdiagnosing migraine. This study can inform management guidelines for new presentations of headache in primary care, particularly when a secondary pathology is suspected.

Debridement of diabetic foot ulcers

BACKGROUND

Foot ulceration is thought to affect 15% of people with diabetes at some time in their lives. Debridement is widely regarded as an effective intervention to speed up ulcer healing. The most effective method is unclear.

OBJECTIVES

To assess the effects of debridement interventions on the healing of diabetic foot ulcers.

SEARCH STRATEGY

For this third update we searched the Cochrane Wounds Group Specialised Register (June 2009); The Cochrane Central Register of Controlled Trials (CENTRAL) - The Cochrane Library 2009, Issue 2; Ovid MEDLINE - 1950 to June Week 3 2009; Ovid EMBASE - 1980 to 2009 Week 25 and Ovid CINAHL - 1982 to June Week 3 2009.

SELECTION CRITERIA

Randomised controlled trials (RCTs) evaluating any method of debriding diabetic foot ulcers and measuring complete healing or rate of healing. There was no restriction on articles/trials based on language or publication status.

DATA COLLECTION AND ANALYSIS

Data extraction and assessment of study quality were undertaken by one review author and checked by an Editor of the Wounds Group.

MAIN RESULTS

Six RCTs of debridement were identified: four assessed hydrogels, with an additional study evaluating larval therapy against hydrogel and one evaluated surgical debridement. Pooling the three RCTs which compared hydrogel with gauze or standard care suggested that hydrogels are significantly more effective in healing diabetic foot ulcers (Relative Risk 1.84, 95% Confidence Interval (CI)1.3 to 2.61). Surgical debridement showed no significant benefit over standard treatment. One small trial suggested that larvae resulted in a more than 50% reduction in wound area compared with hydrogel. Other debridement methods such as enzyme preparations or polysaccharide beads have not been evaluated in diabetic foot ulcers.

AUTHORS' CONCLUSIONS

There is evidence to suggest that hydrogel increases the healing rate of diabetic foot ulcers compared with gauze dressings or standard care and larval therapy resulted in significantly greater reduction in wound area than hydrogel. More research is needed to evaluate the effects of a range of widely used debridement methods and of debridement per se.

Meaning behind measurement: self-comparisons affect responses to health-related quality of life questionnaires

PURPOSE

The subjective nature of quality of life is particularly pertinent to the domain of health-related quality of life (HRQOL) research. The extent to which participants' responses are affected by subjective information and personal reference frames is unknown. This study investigated how an elderly population living with a chronic metabolic bone disorder evaluated self-reported quality of life.

METHODS

Participants (n = 1,331) in a multi-centre randomised controlled trial for the treatment of Paget's disease completed annual HRQOL questionnaires, including the SF-36, EQ-5D and HAQ. Supplementary questions were added to reveal implicit reference frames used when making HRQOL evaluations. Twenty-one participants (11 male, 10 female, aged 59-91 years) were interviewed retrospectively about their responses to the supplementary questions, using cognitive interviewing techniques and semi-structured topic guides.

RESULTS

The interviews revealed that participants used complex and interconnected reference frames to promote response shift when making quality of life evaluations. The choice of reference frame often reflected external factors unrelated to individual health. Many participants also stated that they were unclear whether to report general or disease-related HRQOL.

CONCLUSIONS

It is important, especially in clinical trials, to provide instructions clarifying whether 'quality of life' refers to disease-related HRQOL. Information on self-comparison reference frames is necessary for the interpretation of responses to questions about HRQOL.

What happens to new-onset headache presented to primary care? A case-cohort study using electronic primary care records

In the UK, 4% of general practitioner consultations are for headache, yet the natural history of these presentations is unknown. The objective of this study was to describe the outcome of new headache presentations to the general practitioner. This was a prospective case-control study in adults over a period of 1 year using data from the General Practitioner Research Database, UK. Records of patients who presented with primary headache (migraine, tension-type headache, cluster headache) or undifferentiated headache (no further descriptor) were examined for the subsequent year for subarachnoid haemorrhage, primary brain tumour, benign space-occupying lesion, temporal arteritis, stroke and transient ischaemic attack. We identified 21,758 primary headaches and 63,921 undifferentiated headaches. The likelihood ratio was 29 (9.9, 92) for a subarachnoid haemorrhage after an undifferentiated headache and increased with age. The 1-year risk of a malignant brain tumour with new undifferentiated headache was 0.15%, rising to 0.28% above the age of 50 years. For primary headache the risk was 0.045%. The risk for a benign space-occupying lesion was 0.05% for an undifferentiated and 0.009% for a primary headache. The risk of temporal arteritis was the highest of the conditions studied, 0.66% in the undifferentiated and 0.18% in the primary headache group. Accepting the limitations of this approach, our data can inform management guidelines for new presentations of headache in primary care and confirm the need for follow-up, even if a primary headache diagnosis is made.

GPs' classification of headache: is primary headache underdiagnosed?

With a high economic, social, and personal burden, headache remains an important health problem. How UK GPs diagnose headache in the UK is unknown. In this study, a large primary care database was used and diagnostic categories were described for 91121 adult patients with new-onset headache, that is, patients who had not consulted for headache in the previous year. Seventy per cent of headaches were not given a diagnostic label, 24% were diagnosed as primary, and 6% as secondary headaches. It is suggested that GPs' difficulty in diagnosing headache presentations contributes to the high level of morbidity and unmet need in this disease.

The mortality of colorectal cancer in relation to the initial symptom at presentation to primary care and to the duration of symptoms: a cohort study using medical records

The association between the staging of colorectal cancer and mortality is well known. Much less researched is the relationship between the duration of symptoms and outcome, and whether particular initial symptoms carry a different prognosis. We performed a cohort study of 349 patients with primary colorectal cancer in whom all their prediagnostic symptoms and investigation results were known. Survival data for 3–8 years after diagnosis were taken from the cancer registry. Six features were studied: rectal bleeding, abdominal pain, diarrhoea, constipation, weight loss, and anaemia. Two of these were significantly associated with different staging and mortality. Rectal bleeding as an initial symptom was associated with less advanced staging (odds ratio from one Duke's stage to the next 0.50, 95% confidence interval 0.31, 0.79; P=0.003) and with reduced mortality (Cox's proportional hazard ratio (HR) 0.56 (0.41, 0.79); P=0.001. Mild anaemia, with a haemoglobin of 10.0–12.9 g dl⁻¹, was associated with more advanced staging (odds ratio 2.2 (1.2, 4.3); P=0.021) and worse mortality (HR 1.5 (0.98, 2.3): P=0.064). When corrected for emergency admission, sex, and the site of the tumour, the HR for mild anaemia was 1.7 (1.1, 2.6); P=0.015. No relationship was found between the duration of symptoms and staging or mortality.

Negative chest X-rays in primary care patients with lung cancer

BACKGROUND

The main investigation for suspected lung cancer in primary care is a chest X-ray. Reports from secondary care show that some patients with normal chest X-rays transpire to have lung cancer. The assumption is that this occurs rarely in primary care.

AIM

The aim of this study was to examine the frequency of misleading chest X-rays in primary care, and whether there were any particular symptoms associated with them.

DESIGN OF STUDY

Retrospective cohort study of the primary care records of 247 lung cancer patients diagnosed between 1998-2002.

SETTING

All general practices in Exeter Primary Care Trust, Devon, UK.

METHOD

All chest X-rays and all common symptoms of lung cancer reported to primary care were identified from the medical records. X-ray results were categorised into three groups by the radiologist's report: normal; abnormal but no malignancy suspected (together classified as negative X-rays); or abnormal with possible malignancy.

RESULTS

Of the 247 patients, 164 (66%) had a chest X-ray taken in primary care during the year before diagnosis: 126 of these (77%) were abnormal with possible malignancy; 21 (13%) were abnormal but with no malignancy suspected; in 17 (10%) the X-ray was reported as normal. Thus, 38 of 164 patients (23%; 95% confidence interval = 16 to 32%) had a negative X-ray. Negative X-rays were less common in the 90 days before diagnosis. No particular symptoms were significantly associated with negative X-rays.

CONCLUSION

Nearly a quarter of chest X-rays requested from primary care in lung cancer patients are negative. Further investigation is warranted with continuing or changing symptoms, even if the X-ray is not suggestive of malignancy.

Tamoxifen and norethisterone: effects on plasma cholesterol and total body calcium content in the estrogen-deficient rat

It is important that drugs which are used to protect bone from the osteoporotic effects of estrogen deficiency should not affect plasma lipids adversely. Effects of a) norethisterone acetate and b) tamoxifen citrate on plasma cholesterol and on bone conservation in rats with normal plasma 17B-estradiol and in rats made estrogen-deficient with the LHRH agonist, buserelin are reported. Tamoxifen halved total plasma cholesterol (p < 0.01), whereas norethisterone did not lower plasma cholesterol. Furthermore tamoxifen fully protected bone from estrogen-deficiency osteopenia whereas norethisterone conserved bone less well. Reductions in cholesterol elicited by tamoxifen were similar in estrogen-deficient rats and in rats with normal ovarian function. This is the first report in the rat that tamoxifen has lipid-lowering actions. It is suggested the rat may be useful for future investigations of the lipid-lowering mechanisms of tamoxifen.
