Piloting a new approach in primary care to identify, assess and support carers of people with terminal illnesses: a feasibility study.

BACKGROUND: General practices in the United Kingdom are encouraged to have a protocol for the identification of carers and a mechanism for social care referral. However, a minority of carers are identified and those caring for someone with a terminal illness often cope until the situation becomes overwhelming. Earlier identification could enable more timely support. The aim of this project was to model and pilot a systematic approach to identify, assess and support carers of people with supportive and palliative care needs in primary care. METHOD: The intervention was modelled on the Medical Research Council complex intervention framework with a preliminary theoretical phase, which has been reported elsewhere. In this study, which lasted 12 months, four general practices were recruited. Each practice identified a 'carer liaison' person to take the lead in identifying carers, followed by assessment and support using a toolkit modelled from the earlier phase. Qualitative evaluation interviews were conducted with carers who had received the intervention and the carer liaisons and general practitioners in the pilot practices. A stakeholder event was held to disseminate and deliberate the findings. RESULTS: The practices' populations ranged from 5840 to 10832 patients and across the four practices, 83 carers were identified. Thirty six carers were identified from practice registers (disease - 16; palliative care - 9; carer - 11; advanced care plan - 12), whilst 28 were identified opportunistically by practice staff at appointments or at home. Seven carers self-identified. Overall, 81 carers received the carer pack and 25 returned the Carer Support Needs Assessment Tool (CSNAT) form. Eleven carers received a follow up call from the practice to discuss support and 12 were also referred/signposted for support. Qualitative interviews suggest carers valued connection with their practices but the paperwork in the toolkit was onerous. CONCLUSION: This approach to identifying and supporting carers was acceptable, but success was dependent on engagement within the whole practice. Carers did not tend to self-identify, nor ask for help. Practices need to proactively identify carers using existing opportunities, resources and computer systems, and also adopt a public health approach to raise carer awareness and perceived support within their communities.

Understanding the barriers to identifying carers of people with advanced illness in primary care: triangulating three data sources.

BACKGROUND: Approximately 10% of the UK population have an unpaid caring role for a family member or friend. Many of these carers make a significant contribution to supporting patients at the end of life. Carers can experience poor physical and psychosocial wellbeing, yet they remain largely unsupported by health and social care services. Despite initiatives for general practices to identify carers and their needs, many remain unidentified. Neither are carers self-identifying and requesting support. This study set out to explore the barriers to, and consider strategies for, identifying carers in primary care. METHODS: We integrated findings from three data sources - a review of the caregiving literature; a workshop with researchers who have undertaken research with those caring at the end of life, and focus groups with carers and health professionals. RESULTS: Three categories of barrier emerged. 1) Taking on the care of another person is often a gradual process, carers did not immediately identify with being a 'carer' - preferring to think of themselves in relational terms to the patient e.g. spouse, sibling, son or daughter. Often it was health and social care professionals who encouraged carers to consider themselves as an unpaid carer. 2) As the cared-for person's condition deteriorated, the caring role often became all-encompassing so that carers were managing competing demands, and felt unable to look after their own needs as well as those of the cared-for person. 3) There was ambiguity about the legitimacy of carer needs and about the role of the primary health care team in supporting carers, from both the perspective of the carers and the health professionals. GPs were thought to be reactive rather than proactive which discouraged carers from asking for help. CONCLUSIONS: The needs of carers have to be legitimised to ensure primary care staff are proactive in their approach and carers are empowered to utilise the support available. Strategies to identify carers have to be sensitive to the complex dynamics of a caring relationship as well as the primary care context. Identification is a key factor in improving support for carers themselves and to enable them to support the patient.

Are UK primary care teams formally identifying patients for palliative care before they die?

BACKGROUND: The palliative care approach has the potential to improve care for patients with progressive life-threatening illnesses from the time of diagnosis. Policy and clinical directives in the UK advocate early identification. AIM: To determine the extent to which practices identify patients for palliative care, including factors influencing early identification and possible effects on place of death. DESIGN AND SETTING: Qualitative and quantitative data were collected from six general practices from three Scottish NHS boards and analysed. METHOD: Records of patients who had died in the previous 6 months were analysed and interviews with practice staff (n = 21) and with patients currently on the practice palliative care register and bereaved relatives (n = 14) were conducted. In addition, a practice meeting was observed. RESULTS: In total, 29% of patients who died were recorded as being on the practice palliative care register before death. Two-thirds of patients with cancer were recorded on the register, but for those with non-malignant conditions only around 20% had any palliative care documented. This was a result of GPs not finding the current guidelines useful and being reluctant to discuss palliative care overtly with patients early in their illness. Palliative care services and documentation were geared towards patients with cancer. More district nurses than GPs saw the benefits of inclusion on the palliative care register. Only 25% of patients on the register died in hospital. CONCLUSION: Most patients with advanced progressive illnesses, especially those with non-malignant disease, are not being formally identified for a palliative care approach before they die. Those identified are more likely to benefit from coordinated care and may be more likely to die at home.

Infectious mononucleosis in university students in the United kingdom: evaluation of the clinical features and consequences of the disease.

BACKGROUND: Infectious mononucleosis (IM) is common among university students. We undertook to analyze the clinical features and sequelae of the disease in a cohort of students at Edinburgh University. METHODS: Consecutive IM case patients were recruited from 2000 through 2002 at the University Health Service after diagnosis of IM. RESULTS: IM resulted in marked reductions in student study time, physical exercise, and non-exercise-related social activities, and sustained increases in reported number of hours of sleep. The disease profile differed between the sexes, with significantly more females reporting fatigue, which was more likely to be prolonged (P = .003) and to lead to loss of study time (P = .013). Female case patients were more likely to discontinue their studies following IM (16% vs 0%; P = .056). Within the typically elevated lymphocyte counts in IM, we identified an elevated gammadelta T cell component that may contribute to the disease pathogenesis. CONCLUSIONS: IM results in substantial morbidity among university students, reported as more profound in females, and affecting academic studies, physical exercise, and social activities. Immunization to prevent IM and strategies to reduce post-IM disability would be beneficial in this population.

A study of risk factors for acquisition of Epstein-Barr virus and its subtypes.

BACKGROUND: Risk factors for primary infection with Epstein-Barr virus (EBV) and its subtypes have not been fully investigated. METHODS: Questionnaires and serum samples from a total of 2006 students who entered Edinburgh University in 1999-2000 were analyzed to examine risk factors for EBV seropositivity, both overall and by EBV type. RESULTS: The prevalence of EBV seropositivity was significantly increased among females, older students, those who had lived in tropical countries, those with siblings, and those who were sexually active, particularly if they had had numerous sex partners. Risk was lower (1) among students who always used a condom than among those who had sexual intercourse without one and (2) among female oral-contraceptive users than among sexually active nonusers. Risk factors for type 1 EBV infection were similar to those for EBV overall. No associations were found between nonsexual risk factors and type 2 infection. Sexual activity increased the risk of type 2 infection, but the increase in risk with number of sex partners was less consistent than for type 1 infections. Dual infection was uncommon, but the patterns of risk appeared to be similar to those of type 1 infection. CONCLUSION: This study provides further evidence that EBV may be sexually transmitted and some suggestion that the risk factors for type 1 and type 2 infection differ.

Evidence of shared Epstein-Barr viral isolates between sexual partners, and low level EBV in genital secretions.

Epstein-Barr virus is present in the saliva of most persistently infected individuals and is generally thought to be spread by close oral contact. However, there are now several reports of EBV in genital secretions, suggesting the possibility of sexual transmission between adults. The present study was undertaken to investigate the risk of sexual transmission of EBV. PCR analysis was used to examined the degree to which a group (n = 11) of patients with infectious mononucleosis (IM) shared the same viral isolates as their sexual partners, and compare this to the extent of isolate sharing among a different group (n = 18) of IM patients and their non-sexual contacts. There was significantly more sharing of EBV isolates among the IM/sexual-contact pairs than among the IM/non-sexual-contact pairs (P = 0.0012). Female cervical (n = 84), male urethral (n = 55), and semen (n = 30) samples from asymptomatic, unselected volunteers were analyzed for the presence of EBV DNA, revealing 7%, 5%, and 3% to be EBV positive, respectively. Fractionation of cervical and urethral samples into cellular and supernatant fluid components showed EBV to be mainly cell-associated. Quantitation of EBV in these samples gave levels of below 10 EBV genomes per microg of DNA. Overall the findings support the possibility that EBV could on occasions be transmitted sexually, however, the low levels detected in genital secretions compared to saliva suggest that this is not a major transmission route. The finding of small quantities of cell-associated virus suggests a latent infection; thus EBV is probably in the B lymphocyte rather than in the epithelial cell component of the secretions.

A cohort study among university students: identification of risk factors for Epstein-Barr virus seroconversion and infectious mononucleosis.

BACKGROUND: A vaccine against Epstein-Barr virus (EBV) infection is in clinical trials. Up-to-date information on risk factors for EBV infection and infectious mononucleosis (IM) among young adults is required to inform a vaccination strategy. METHODS: We carried out a prospective study on a cohort of university students. All EBV-seronegative students were asked to report symptoms of IM and were followed up 3 years later to undergo repeat EBV testing and to complete a lifestyle questionnaire. EBV typing was performed for these subjects, as well as for students who were EBV seropositive at enrollment and for additional students with IM. RESULTS: A total of 510 students (25%) who took part in the study were EBV seronegative when they entered the university; of the 241 who donated a second blood sample 3 years later, 110 (46%) had seroconverted to EBV, 27 (25%) of whom developed IM [corrected] Penetrative sexual intercourse was a risk factor for EBV seroconversion (P = .004), but neither condom use nor oral sex significantly altered the rate of seroconversion. EBV type 1 was significantly overrepresented in IM, compared with silent seroconversion (P = .001). CONCLUSIONS: Our findings suggest that acquisition of EBV is enhanced by penetrative sexual intercourse, although transmission could occur through related sexual behaviors, such as "deep kissing." We also found that EBV type 1 infection is significantly more likely to result in IM. Overall, the results suggest that a large EBV type 1 load acquired during sexual intercourse can rapidly colonize the B cell population and induce the exaggerated T cell response that causes IM. Thus, IM could, perhaps, be prevented with a vaccine that reduces the viral load without necessarily inducing sterile immunity.

The immune response to primary EBV infection: a role for natural killer cells.

The role of antigen-specific CD3(+)CD8(+) cytotoxic T cells in the control of primary Epstein-Barr Virus (EBV) infection is well established. However, time is required for the antigen-specific immune response to develop and expand. In contrast, innate immune responses, such as natural killer (NK) cells, are considered vital early in the infection process. We analysed the scale, phenotype and function of the NK cell response during symptomatic primary EBV infection, infectious mononucleosis (IM) and showed that NK cell numbers were significantly elevated both at diagnosis of IM and in the first month following diagnosis. There were also significant changes in cell phenotype and function, an increase in the proportion of CD56(bright) cells at diagnosis, and freshly isolated cells showing an enhanced ability to kill EBV-infected cell lines. Moreover, in our cohort of IM patients higher NK cell counts were associated with significantly lower viral load in peripheral blood. Our results suggest NK cells have an important role in the control of primary EBV infection by eliminating infected B cells and augmenting the antigen-specific T cell response via release of immunomodulatory cytokines. The magnitude of the NK cell response may ultimately determine whether primary EBV infection has a clinical outcome.

The high prevalence of bipolar spectrum disorders in young adults with recurrent depression: toward an innovative diagnostic framework.

BACKGROUND: Young adults with early-onset major depressive disorder (MDD) may be at high risk of progression to bipolar disorder. Although hypomanic symptoms are common in young people with depression, many do not reach the strict DSM-IV and ICD-10 criteria for hypomania. We used an emerging innovative framework for bipolar spectrum to evaluate this question. METHODS: Consecutive referrals to a psychiatric outpatient clinic at a university health service were assessed for recurrent episodes of depression. DSM-IV diagnoses were based on a SCID-1 interview. We used two approaches to delineate bipolar spectrum. The first focused on bipolar spectrum disorder (BSD, as defined by Ghaemi et al. [Can. J. Psychiatry 47 (2002) 125]), and the second on a symptoms perspective based on MDD with a history of hypomanic symptoms, using a 15-point hypomanic symptoms checklist with a cut-off > or =8 or more symptoms (modified from J. Affect. Disord. 73 (2003) 39 and J. Affect. Disord. 73 (2003) 73). Data were also obtained on family history of affective disorder, course and number of episodes of depression, symptom severity, psychosocial functioning, suicidality and deliberate self-harm, and drug and alcohol use. RESULTS: High rates of bipolar and bipolar spectrum disorder were identified. Under DSM-IV, 14 subjects (16.1%) had bipolar affective disorder and 73 subjects (83.9%) had recurrent MDD. Depending on the method used to diagnose bipolar spectrum, between 47.1% and 77.0% of the total cohort could be so diagnosed. Hypomanic symptom counts, irrespective of duration, yielded the highest estimates for bipolar spectrum. High rates of pharmacological hypomania were also identified: 12 subjects (16.4%) with recurrent MDD group reported this, and all could be diagnosed with bipolar spectrum. LIMITATIONS: The reliability of using the 15-point hypomanic scale for the diagnostic assignments was not tested. All subjects were recruited from a university health service and, given the affluence of their parents, findings may not generalise to other populations. Most importantly, because bipolar family history and pharmacological hypomania were part of the diagnostic criteria of the BSD group, they could not be used as external validators for Ghaemi's BSD construct. CONCLUSIONS: Bipolar disorders emerge as extremely common in this cohort of young adults with recurrent depression. Antidepressant-induced hypomania and high scores on a hypomanic symptoms checklist help to identify patients who are likely to have a bipolar spectrum illness, but who do not meet DSM-IV criteria for bipolar disorder. This is a preliminary study, and further evidence from external validating strategies are needed to verify the bipolar status of these patients in a larger and unselected cohort representing a broader socio-economic demographic profile.

Analysis of immune activation and clinical events in acute infectious mononucleosis.

The symptoms of infectious mononucleosis (IM) are thought to be caused by T cell activation and cytokine production. Surface lymphocyte activation marker (SLAM)-associated protein (SAP) regulates lymphocyte activation via signals from cell-surface CD244 (2B4) and SLAM (CD150). We followed T cell activation via this SAP/SLAM/CD244 pathway in IM and analyzed whether the results were associated with clinical severity. At diagnosis, SAP, SLAM, and CD244 were significantly up-regulated on CD4 and CD8 T cells; expression decreased during IM, but CD244 and SLAM levels remained higher on CD8 cells 40 days later. There were significantly more lymphocytes expressing CD8 and CD244/CD8 in patients with severe sore throat. The expression of CD8 alone and CD244 on CD8 cells correlated with increased virus load. We suggest that T cells expressing CD244 and SLAM are responsible for the clinical features of IM but that the control of activation is maintained by parallel increased expression of SAP.

Sexual history and Epstein-Barr virus infection.

To determine the role of sexual contact in transmission of Epstein-Barr virus (EBV) and occurrence of infectious mononucleosis (IM), a cross-sectional study was undertaken of EBV serologic testing and histories of IM and sexual behavior among 1006 new students at Edinburgh University. Prevalence of EBV seropositivity was significantly greater among women (79.2%) than among men (67.4%; P<.001) and among those who had ever been sexually active (82.7%) than among those who had not (63.7%; P<.001). Having a greater number of sex partners was a highly significant risk factor for EBV seropositivity. Two thirds of IM cases, but only a tenth of asymptomatic primary EBV infections, were statistically attributable to sexual intercourse. The findings suggest that EBV transmission occurs during sexual intercourse or closely associated behaviors. Transmission in this way appears to account for most cases of IM but for only a minority of cases of asymptomatic EBV infection, which mainly occur at younger ages.
