Considerations for Antiplatelet Management of Carotid Stenting in the Setting of Mechanical Thrombectomy: A Delphi Consensus Statement

BACKGROUND AND PURPOSE

There are only few data and lack of consensus regarding antiplatelet management for carotid stent placement in the setting of endovascular stroke treatment. We aimed to develop a consensus-based algorithm for antiplatelet management in acute ischemic stroke patients undergoing endovascular treatment and simultaneous emergent carotid stent placement.

MATERIALS AND METHODS

We performed a literature search and a modified Delphi approach used Web-based questionnaires that were sent in several iterations to an international multidisciplinary panel of 19 neurointerventionalists from 7 countries. The first round included open-ended questions and formed the basis for subsequent rounds, in which closed-ended questions were used. Participants continuously received feedback on the results from previous rounds. Consensus was defined as agreement of ≥70% for binary questions and agreement of ≥50% for questions with >2 answer options. The results of the Delphi process were then summarized in a draft manuscript that was circulated among the panel members for feedback.

RESULTS

A total of 5 Delphi rounds were performed. Panel members preferred a single intravenous aspirin bolus or, in jurisdictions in which intravenous aspirin is not available, a glycoprotein IIb/IIIa receptor inhibitor as intraprocedural antiplatelet regimen and a combination therapy of oral aspirin and a P2Y12 inhibitor in the postprocedural period. There was no consensus on the role of platelet function testing in the postprocedural period.

CONCLUSIONS

More and better data on antiplatelet management for carotid stent placement in the setting of endovascular treatment are urgently needed. Panel members preferred intravenous aspirin or, alternatively, a glycoprotein IIb/IIIa receptor inhibitor as an intraprocedural antiplatelet agent, followed by a dual oral regimen of aspirin and a P2Y12 inhibitor in the postprocedural period.

Antiplatelet Management for Stent-Assisted Coiling and Flow Diversion of Ruptured Intracranial Aneurysms: A DELPHI Consensus Statement

BACKGROUND AND PURPOSE

There is a paucity of data regarding antiplatelet management strategies in the setting of stent-assisted coiling/flow diversion for ruptured intracranial aneurysms. This study aimed to identify current challenges in antiplatelet management during stent-assisted coiling/flow diversion for ruptured intracranial aneurysms and to outline possible antiplatelet management strategies.

MATERIALS AND METHODS

The modified DELPHI approach with an on-line questionnaire was sent in several iterations to an international, multidisciplinary panel of 15 neurointerventionalists. The first round consisted of open-ended questions, followed by closed-ended questions in the subsequent rounds. Responses were analyzed in an anonymous fashion and summarized in the final manuscript draft. The statement received endorsement from the World Federation of Interventional and Therapeutic Neuroradiology, the Japanese Society for Neuroendovascular Therapy, and the Chinese Neurosurgical Society.

RESULTS

Data were collected from December 9, 2019, to March 13, 2020. Panel members achieved consensus that platelet function testing may not be necessary and that antiplatelet management for stent-assisted coiling and flow diversion of ruptured intracranial aneurysms can follow the same principles. Preprocedural placement of a ventricular drain was thought to be beneficial in cases with a high risk of hydrocephalus. A periprocedural dual, intravenous, antiplatelet regimen with aspirin and a glycoprotein IIb/IIIa inhibitor was preferred as a standard approach. The panel agreed that intravenous medication can be converted to oral aspirin and an oral P2Y12 inhibitor within 24 hours after the procedure.

CONCLUSIONS

More and better data on antiplatelet management of patients with ruptured intracranial aneurysms undergoing stent-assisted coiling or flow diversion are urgently needed. Panel members in this DELPHI consensus study preferred a periprocedural dual-antiplatelet regimen with aspirin and a glycoprotein IIb/IIIa inhibitor.

The effect of hypoglycaemia during hospital admission on health-related outcomes for people with diabetes: a systematic review and meta-analysis

AIM

To assess the health-related outcomes of hypoglycaemia for people with diabetes admitted to hospital; specifically, hospital length of stay and mortality.

METHODS

We conducted a systematic review and meta-analysis of studies relating to hypoglycaemia (< 4 mmol/l) for hospitalized adults (≥ 16 years) with diabetes reporting the primary outcomes of interest, hospital length of stay or mortality. Final papers for inclusion were reviewed in duplicate and the adjusted results of each were pooled, using a random effects model then undergoing further prespecified subgroup analysis.

RESULTS

In total, 15 studies were included in the meta-analysis. The pooled mean difference in length of stay for ward-based inpatients exposed to hypoglycaemia was 4.1 days longer [95% confidence interval (CI) 2.36 to 5.79; I² = 99%] compared with those without hypoglycaemia. This association remained robust across the pre-specified subgroup analyses. The pooled relative risk (RR) of in-hospital mortality was greater for those exposed to hypoglycaemia (RR 2.09, 95% CI 1.64 to 2.67; I² = 94%, n = 7 studies) but not in intensive care unit mortality (RR 0.75, 95% CI 0.49 to 1.16; I² =0%, n = 2 studies).

CONCLUSION

There is an association between inpatient hypoglycaemia and longer length of stay and greater in-hospital mortality. Studies examining this association were heterogenous in terms of both clinical populations and effect size, but the overall direction of the association was consistent. Therefore, glucose concentration should be considered a potential tool to aid the identification of inpatients at risk of poor health-related outcomes.

Human Skeletal Allograft Collection — Room for Improvement?

Aim: To assess the efficiency of skeletal allograft collection from patients undergoing primary joint arthroplasty at a District General Orthopaedic Unit. Methods: A two cycle audit was performed. Between cycles procedural changes were implemented to improve the efficiency of allograft collection. The discard rate of donated allograft was also assessed during each cycle. Results: Initially 80 patients were identified. Eight (8/80) did not donate allograft due to medical contraindications. Two (2/80) patients underwent intra-operative autologous born grafting. Allograft was not collected from 22 (22/70) suitable patients. As such only 68.6% of suitable bone was collected by the West of Scotland Blood Transfusion Service (WSBTS). Subsequently 100 patients were studied. Twenty-eight (28/100) patients did not donate allograft due to medical contra-indications. Two (2/100) patients underwent intra-operative autologous bone grafting. Eight (8/70) allografts were discarded as a result of logistical problems. As such 88.9% of suitable allograft was collected. Initially 29% of all allograft donated was rejected due to poor patient selection. This subsequently fell to 9.4%. Conclusion: By auditing the collection process a significant improvement (c2 = 7.17 df = 1 p = 0.001) in the efficiency of allograft collection was achieved. This was complemented by a significant reduction(c2 = 6.09 df= 1 p=0.05) in the proportion of unsuitable allograft donated to the WSBTS.

Open reduction and plate fixation versus nonoperative treatment for displaced midshaft clavicular fractures: a multicenter, randomized, controlled trial

BACKGROUND

There is a growing trend to treat displaced midshaft clavicular fractures with primary open reduction and plate fixation; whether such treatment results in improved patient outcomes is debatable. The aim of this multicenter, single-blinded, randomized controlled trial was to compare union rates, functional outcomes, and economic costs for displaced midshaft clavicular fractures that were treated with either primary open reduction and plate fixation or nonoperative treatment.

METHODS

In a prospective, multicenter, stratified, randomized controlled trial, 200 patients between sixteen and sixty years of age who had an acute displaced midshaft clavicular fracture were randomized to receive either primary open reduction and plate fixation or nonoperative treatment. Functional assessment was conducted at six weeks, three months, six months, and one year with use of the Disabilities of the Arm, Shoulder and Hand (DASH) and Constant scores. Union was evaluated with use of three-dimensional computed tomography. Complications were recorded, and an economic evaluation was performed.

RESULTS

The rate of nonunion was significantly reduced after open reduction and plate fixation (one nonunion) as compared with nonoperative treatment (sixteen nonunions) (relative risk = 0.07; p = 0.007). Group allocation to nonoperative treatment was independently predictive of the development of nonunion (p = 0.0001). Overall, DASH and Constant scores were significantly better after open reduction and plate fixation than after nonoperative treatment at the time of the one-year follow-up (DASH score, 3.4 versus 6.1 [p = 0.04]; Constant score, 92.0 versus 87.8 [p = 0.01]). However, when patients with nonunion were excluded from analysis, there were no significant differences in the Constant scores or DASH scores at any time point. Patients were less dissatisfied with symptoms of shoulder droop, local bump at the fracture site, and shoulder asymmetry in the open reduction and plate fixation group (p < 0.0001). The cost of treatment was significantly greater after open reduction and plate fixation (p < 0.0001).

CONCLUSIONS

Open reduction and plate fixation reduces the rate of nonunion after acute displaced midshaft clavicular fracture compared with nonoperative treatment and is associated with better functional outcomes. However, the improved outcomes appear to result from the prevention of nonunion by open reduction and plate fixation. Open reduction and plate fixation is more expensive and is associated with implant-related complications that are not seen in association with nonoperative treatment. The results of the present study do not support routine primary open reduction and plate fixation for the treatment of displaced midshaft clavicular fractures.

An analysis of knowledge and attitudes of hospice staff towards organ and tissue donation

BACKGROUND

Only a minority of hospice patients eligible to donate tissue and organs choose to do so. Hospice care staff play a key role in discussions about donation, but their willingness to engage in these discussions and their understanding of issues around tissue and organ donation is poorly understood.

AIMS

To (i) identify factors associated with the wish of hospice doctors, nurses and healthcare assistants to donate their own organs after death; (ii) survey the experience of discussing the subject with patients; (iii) determine staff members' knowledge of organ and tissue donation and (iv) identify factors associated with knowledge of organ and tissue donation.

DESIGN

Cross-sectional questionnaire survey of hospice care staff.

SETTING/PARTICIPANTS

76 of the 94 care staff of one large UK hospice completed and returned the questionnaire.

RESULTS

Staff wishing to donate their organs after death (43/76 56.6%) were more likely to be doctors or nurses than healthcare assistants (p=0.011) and more likely to have discussed organ or tissue donation with their family (p<0.001). Staff reporting ever having discussed donation with patients had more years' experience (p=0.045) and had similarly discussed donation with their own family (p=0.039). Those with greater knowledge were more likely to have discussed organ or tissue donation with a patient (p=0.042).

CONCLUSIONS

A reluctance to instigate discussions about organ and tissue donation may prevent palliative patients and their families being allowed the opportunity to donate. Suboptimal knowledge among hospice staff suggests the need for greater liaison between hospice staff, and the organ and tissue donation teams.

Treatment options and time course for intramedullary spinal cord metastasis. Report of three cases and review of the literature

Surgical treatment of intrameduallary spinal cord metastases (ISCM) has become increasingly effective in recent years. The advent of new imaging techniques combined with an enhanced understanding of the natural history of these tumors has improved the effectiveness of the available treatment options. The authors present three new cases of ISCM successfully treated with surgery. A review of 129 cases found in the literature is also discussed. Characteristic symptomology and presentation are reviewed with an eye toward improving diagnostic methodology. The natural history of ISCM is divided into three phases. Surgical intervention should be used early in phase 2.

Development and testing of a cancer appetite and symptom questionnaire

BACKGROUND

Poor appetite and weight loss are common in patients with cancer, contributing to an increase in morbidity and mortality. Early identification of those at greatest risk is problematic. The Council on Nutrition Appetite Questionnaire (CNAQ) is short and easy to use, although it is not specific to cancer populations. The present study aimed to build on the CNAQ to develop a cancer appetite and symptom questionnaire (CASQ) for predicting weight loss in patients with cancer.

METHODS

The content validity of the CNAQ was assessed by an expert panel (n = 41) using the content validity index (CVI). The resulting CASQ was tested for reliability among patients receiving radiotherapy (n = 34). Predictive validity of the CASQ was determined in patients with lung or upper gastrointestinal cancer (n = 185), comparing CASQ scores (possible range 0-48) recorded at baseline with percentage weight change after 12 weeks.

RESULTS

 In all but one CNAQ item, the CVI was above the minimum level of agreement (>0.70). Comments from expert panel members led to minor modifications and the introduction of new items resulting in the 12-item CASQ. The intraclass correlation coefficient of the CASQ was 0.80 [95% confidence interval (CI) = 0.68-0.92] and the difference between total scores at two time points was -0.20 (95% CI = -1.21 to 0.80). The optimum cut-off point of the instrument to predict >10% weight loss was 29/30 (area under curve = 0.75; sensitivity 71%, specificity 66%, positive predictive value 19%, negative predictive value 95%) [Correction added on 30 April 2012, after first online publication: in the preceding sentence, <10% was corrected to >10%].

CONCLUSIONS

The CASQ can predict weight loss among patients with lung and upper gastrointestinal cancer. Acknowledgment of the low positive predictive value is needed if the instrument is to be used within clinical practice.

A study of the safety and harms of antidepressant drugs for older people: a cohort study using a large primary care database

OBJECTIVES

The aim of this study was to establish the relative safety and balance of risks for antidepressant treatment in older people. The study objectives were to (1) determine relative and absolute risks of predefined adverse events in older people with depression, comparing classes of antidepressant drugs [tricyclic and related antidepressants (TCAs), selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs) and other antidepressants] and commonly prescribed individual drugs with non-use of antidepressant drugs; (2) directly compare the risk of adverse events for SSRIs with TCAs; (3) determine associations with dose and duration of antidepressant medication; (4) describe patterns of antidepressant use in older people with depression; and (5) estimate costs of antidepressant medication and primary care visits.

DESIGN

A cohort study of patients aged 65 years and over diagnosed with depression.

SETTING

The study was based in 570 general practices in the UK supplying data to the QResearch database.

PARTICIPANTS

Patients diagnosed with a new episode of depression between the ages of 65 and 100 years, from 1 January 1996 to 31 December 2007. Participants were followed up until 31 December 2008.

INTERVENTIONS

The exposure of interest was treatment with antidepressant medication. Antidepressant drugs were grouped into the major classes and commonly prescribed individual drugs were identified.

MAIN OUTCOME MEASURES

There were 13 predefined outcome measures: all-cause mortality, sudden cardiac death, suicide, attempted suicide/self-harm, myocardial infarction, stroke/transient ischaemic attack (TIA), falls, fractures, upper gastrointestinal bleeding, epilepsy/seizures, road traffic accidents, adverse drug reactions and hyponatraemia.

RESULTS

In total, 60,746 patients were included in the study cohort. Of these, 54,038 (89.0%) received at least one prescription for an antidepressant during follow-up. The associations with the adverse outcomes were significantly different between the classes of antidepressant drugs for seven outcomes. SSRIs were associated with the highest adjusted hazard ratios (HRs) for falls [1.66, 95% confidence interval (CI) 1.58 to 1.73] and hyponatraemia (1.52, 95% CI 1.33 to 1.75), and the group of other antidepressants was associated with the highest HRs for all-cause mortality (1.66, 95% CI 1.56 to 1.77), attempted suicide/self-harm (5.16, 95% CI 3.90 to 6.83), stroke/TIA (1.37, 95% CI 1.22 to 1.55), fracture (1.63, 95% CI 1.45 to 1.83) and epilepsy/seizures (2.24, 95% CI 1.60 to 3.15) compared with when antidepressants were not being used. TCAs did not have the highest HR for any of the outcomes. There were also significantly different associations between the individual drugs for seven outcomes, with trazodone, mirtazapine and venlafaxine associated with the highest rates for several of these outcomes. The mean incremental cost (for all antidepressant prescriptions) ranged between £51.58 (amitriptyline) and £641.18 (venlafaxine) over the 5-year post-diagnosis period.

CONCLUSIONS

This study found associations between use of antidepressant drugs and a number of adverse events in older people. There was no evidence that SSRIs or drugs in the group of other antidepressants were associated with a reduced risk of any of the adverse outcomes compared with TCAs; however, they may be associated with an increased risk for certain outcomes. Among individual drugs trazodone, mirtazapine and venlafaxine were associated with the highest rates for some outcomes. Indication bias and residual confounding may explain some of the study findings. The risks of prescribing antidepressants need to be weighed against the potential benefits of these drugs.

Eph/ephrinB Mediate Dental Pulp Stem Cell Mobilization and Function

Damage to the dentin matrix instigates the proliferation and mobilization of dental progenitor cells to the injury site, the mechanisms of which are not defined. EphB receptors and ephrin-B ligands expressed within the perivascular niche of dental pulp have been implicated following tooth injury. We propose that elevated levels of ephrin-B1 following injury may prevent the proliferation and migration of dental pulp stem cell (DPSC), while EphB/ephrin-B interaction facilitates odontoblastic differentiation. The migration, proliferation, and differentiation of DPSC in response to Eph/ephrin-B molecules was assessed in an established ex vivo tooth injury model and by in vitro assays for the assessment of colony formation and differentiation. Analysis of our data demonstrated that EphB forward signaling promoted DPSC proliferation, while inhibiting migration. Conversely, reverse signaling enhanced DPSC mineral production. These observations suggest that EphB/ephrin-B molecules are important for perivascular DPSC migration toward the dentin surfaces and differentiation into functional odontoblasts, following damage to the dentin matrix.

Frozen shoulder: a clinical review

Frozen shoulder is a common condition which can cause considerable morbidity for a prolonged duration. With recognition of the condition's time scale, management can be directed to help reduce the morbidity. Many treatments are recognized and the gold standard is still to be identified.

Multipotential human adipose-derived stromal stem cells exhibit a perivascular phenotype in vitro and in vivo

Mesenchymal stem-like cells identified in different tissues reside in a perivascular niche. In the present study, we investigated the putative niche of adipose-derived stromal/stem cells (ASCs) using markers, associated with mesenchymal and perivascular cells, including STRO-1, CD146, and 3G5. Immunofluorescence staining of human adipose tissue sections, revealed that STRO-1 and 3G5 co-localized with CD146 to the perivascular regions of blood vessels. FACS was used to determine the capacity of the CD146, 3G5, and STRO-1 specific monoclonal antibodies to isolate clonogenic ASCs from disassociated human adipose tissue. Clonogenic fibroblastic colonies (CFU-F) were found to be enriched in those cell fractions selected with either STRO-1, CD146, or 3G5. Flow cytometric analysis revealed that cultured ASCs exhibited similar phenotypic profiles in relation to their expression of cell surface markers associated with stromal cells (CD44, CD90, CD105, CD106, CD146, CD166, STRO-1, alkaline phosphatase), endothelial cells (CD31, CD105, CD106, CD146, CD166), haematopoietic cells (CD14, CD31, CD45), and perivascular cells (3G5, STRO-1, CD146). The immunoselected ASCs populations maintained their characteristic multipotential properties as shown by their capacity to form Alizarin Red positive mineralized deposits, Oil Red O positive lipid droplets, and Alcian Blue positive proteoglycan-rich matrix in vitro. Furthermore, ASCs cultures established from either STRO-1, 3G5, or CD146 selected cell populations, were all capable of forming ectopic bone when transplanted subcutaneously into NOD/SCID mice. The findings presented here, describe a multipotential stem cell population within adult human adipose tissue, which appear to be intimately associated with perivascular cells surrounding the blood vessels.

A randomised controlled trial of nurse-managed trial conclusion following early phase cancer trial participation

The effect of a nurse-managed intervention, for early phase cancer trial participants at trial conclusion, on psychosocial outcomes was evaluated at two cancer centres in the Midlands, England using a randomised controlled trial. It involved 117 patients who were participating in an early phase cancer clinical trial. It was a nurse-managed trial exit, which included a trial exit interview, trial feedback information leaflet and telephone follow-up compared with standard care at trial conclusion. Psychological distress at 1 week and 4-6 weeks post-trial conclusion, patient's knowledge and understanding and patient's satisfaction were assessed. The results showed there was no significant difference between the two groups regarding scores for anxiety and depression at time one and time two. There is some suggestion that the intervention reduced anxiety from trial conclusion to follow-up (P=0.27). Patients in both groups felt they had contributed to cancer research through trial participation. However, intervention patients were more likely to feel that they knew how the trial was going (P<0.001), knew how other people in the trial were doing (P=0.001), had all the feedback they needed about the trial they took part in (P<0.01) and knew how they would be followed up (P=0.02). Patient satisfaction with the intervention was high (median score=4.5 where 5 is greatest satisfaction). In conclusion, nurse-managed trial conclusion led to positive outcomes for patients who had recently completed a clinical trial.

Impact of bovine tuberculosis on a population of brushtail possums (Trichosurus vulpecula Kerr) in the Orongorongo Valley, New Zealand

Brushtail possums are the main wildlife vectors of bovine tuberculosis (Tb) in New Zealand. Possum–Tb models form the basis of possum control aimed at eradicating the disease, and yet competing models show different behaviour, and are highly sensitive to parameters about which there is considerable uncertainty. One area of great uncertainty is the impact of the disease on possum populations. We investigated the impact of Tb on a local population of brushtail possums in the Orongorongo Valley, Wellington. Bovine Tb was first detected in 1997 at one site within an intensively studied population, but has not been detected in another intensively studied population 3 km away since the early 1980s. Using a Before-After-Control-Impact (BACI) analysis, detection of Tb coincided with a 42% (95% CI = 23–56%) reduction in the odds of apparent yearly survival of a possum >17 months of age, i.e. a decrease in yearly survival from 0.85 to 0.77 in 'good' years, and a decrease from 0.71 to 0.60 in 'bad' years. This suggests that Tb had a significant impact on overall survival. However, there was no impact on local population density in September each year due to compensatory recruitment.

The social functioning of older adults with schizophrenia

A cross-sectional survey of the social functioning of community dwelling older adults was undertaken. Older adults with no psychiatric morbidity, depressed older adults and older adults with schizophrenia were surveyed to see if there were differences in the level of social functioning of the three groups. The setting was two old age psychiatric services, one in an urban area of London and the other in a semi-rural area of Leicestershire. Participants consisted of depressed (n = 81) or normal (n = 101) older persons identified as part of a general practice over 75 years check and clients over 65 years with schizophrenia (n = 30) known to mental health teams for older adults. All participants were interviewed by one of two trained researchers and completed the Mini-Mental State Examination questionnaire, the 15-item Geriatric Depression Scale, a social functioning questionnaire, and the Schedules for Clinical Assessment in Neuropsychiatry or the Brief Psychiatric Rating Scale. In our sample population, community dwelling older persons without any psychiatric diagnosis were the least isolated from their local community, reported more private leisure activities, and had the least contact with professional community services. Clients with schizophrenia reported more isolation from their local community and fewer private leisure activities than clients with a diagnosis of depression.

Isolation and expansion of cytomegalovirus-specific cytotoxic T lymphocytes to clinical scale from a single blood draw using dendritic cells and HLA-tetramers

Cytomegalovirus (CMV) reactivation in immunocompromised recipients of allogeneic stem cell transplantation is a cause of morbidity and mortality from viral pneumonitis. Antiviral drugs given to reactivating patients have reduced the mortality from CMV but have toxic side effects and do not always prevent late CMV disease. Cellular immunotherapy to prevent CMV disease is less toxic and could provide prolonged protection. However, a practical approach to generating sufficient quantities of CMV-specific cytotoxic T cells (CTLs) is required. This study describes a system for generating sufficient CMV-specific CTLs for adoptive immunotherapy of HLA-A*0201 bone marrow transplant recipients from 200 mL donor blood. Donor monocytes are used to generate dendritic cells (DCs) in medium with autologous plasma, interleukin 4, granulocyte-macrophage colony-stimulating factor, and CD40 ligand. The DCs are pulsed with the immunodominant HLA-A*0201-restricted CMV peptide pp65(495-503), and incubated with donor T cells. These cultures are restimulated twice with peptide-pulsed lymphoblastoid cell lines (LCLs) or CD40-ligated B cells and purified with phycoerythrin (PE)-labeled pp65(495-503)/HLA-A*0201 tetramers by flow sorting, or with anti-PE paramagnetic beads. The pure tetramer-positive population is then rapidly expanded to obtain sufficient cells for clinical immunotherapy. The expanded CTLs are more than 80% pure, of memory phenotype, with a Tc1 cytokine profile. They efficiently kill CMV-infected fibroblasts and express the integrin VLA-4, suggesting that the CTLs could cross endothelial barriers. This technique is reproducible and could be used for generating CMV-specific CTLs to prevent CMV disease after allogeneic blood and marrow transplantation. (Blood. 2001;98:505-512)

Treatments for late life depression in primary care--a systematic review

BACKGROUND

Depression is common among older people. It is associated with increased mortality and use of health services. We could identify no prior systematic review of treatment for depression in either primary care attenders or population samples of older people.

OBJECTIVES

The aim of this study was to carry out a systematic review of trials of treatments for depression of patients over 60 years of age in primary care or population samples.

METHODS

We searched Medline, Embase, Cinahl, the Cochrane Library, Psyclit, BIDS--Social Science and BIDS--Science Citation Indices for trials of drug treatment, interpersonal psychotherapy, cognitive behavioural psychotherapy, counselling and social interventions for late life depression in English, French or German published between 1980 and June 1999.

RESULTS

Of the studies identified, only two were of patients over 60 years of age and met all inclusion criteria for content and quality. Three further studies that were not restricted to but included patients over the age of 60 years also fulfilled our criteria. We found no studies of psychological therapies for depression in older people. With few exceptions, studies were limited to older people who reached a diagnostic threshold and excluded those with 'subcase level depression'.

CONCLUSION

There is little evidence of effectiveness for a variety of treatment approaches for depression in older people in primary care, particularly in those with less severe depression. As older people take more medication, making contra-indications to the use of antidepressant drugs more likely, there is a pressing need for studies of the efficacy of non-pharmacological interventions in primary care settings.

Informal caring in late life: a qualitative study of the experiences of older carers

AIM OF THE STUDY

This study examined the experiences of informal carers who were aged 75 years and over.

BACKGROUND

It has been estimated that 13% of those aged over 65 years are providing some form of informal care. Although there is a substantial body of work reporting the experiences of informal carers, little attention has been paid to the specific situation faced by older carers.

DESIGN AND METHODS

Potential study participants were identified during one round of annual over-75 health checks carried out in one large general practice. Data were collected through personal interviews, which were transcribed and analysed using a thematic approach.

RESULTS

Fifty-eight carers were identified and 14 were approached to take part in the study. Of the 14 interviewees, 13 were caring for a spouse and one was caring for a sibling. There were 10 female and four male carers in the study (age range 76-92 years). Themes to emerge from the interviews were categorized under four headings: (1) the organizational demands and structure of the caring relationship, (2) informal support networks, (3) formal services and (4) the constancy of caring and the need for the role of carer to be recognized.

CONCLUSIONS

The over-75 health check may provide a valuable tool to identify older carers who are not known to care providers. This paper concludes that nurses can take a lead role in working with this group in three ways. Firstly, in identifying older carers; secondly, in developing strategies to assist older carers in their caring role and finally, in responding swiftly to crises that can develop among this vulnerable group.
