Objectives. As a disease typified by early onset and chronic disease course, caring for a person with schizophrenia may have a significant impact on caregivers' lives. This study aimed to investigate the subjective experiences of caregivers of people with schizophrenia as a means of understanding “caregiver burden” in this population. Methods. Face-to-face qualitative interviews were conducted with a diverse sample of 19 US-English speaking caregivers of people with schizophrenia (who were at least moderately ill). Interview transcripts were analyzed using grounded theory methods and findings used to inform the development of a preliminary conceptual model outlining caregivers' experiences. Results. Findings support assertions that people with schizophrenia were largely dependent upon caregivers for the provision of care and caregivers subsequently reported lacking time for themselves and their other responsibilities (e.g., family and work). Caregiver burden frequently manifested as detriments in physical (e.g., fatigue, sickness) and emotional well-being (e.g., depression and anxiety). Conclusions. Caring for a person with schizophrenia has a significant impact on the lives of informal (unpaid) caregivers and alleviating caregiver burden is critical for managing individual and societal costs. Future research should concentrate on establishing reliable and valid means of assessing burden among caregivers of persons with schizophrenia to inform the development and evaluation of interventions for reducing this burden.

BackgroundHerpes zoster (HZ) is a painful condition that can have a substantial negative impact on patients’ lives. However, UK-specific data on the debilitating impact of HZ, in terms of patients’ experience of pain and impairments in Health-Related Quality of Life (HRQoL) are limited. The Zoster Quality of Life (ZQOL) study, a large-scale UK cross-sectional study, was conducted to quantify the burden of HZ in UK patients.MethodsA total of 229 HZ patients aged 50 years or over were recruited from primary and secondary/tertiary care centres throughout the UK. Patients completed a battery of validated questionnaires, including the Zoster Brief Pain Inventory (ZBPI), the Medical Outcomes Study Short-Form 36 (SF-36) and the EuroQol-5 Dimensions (EQ-5D) on initial presentation to the doctor and again 7–14 days later. At follow-up patients also completed the Treatment Satisfaction with Medication (TSQM) questionnaire. Where available, mean questionnaire scores in the HZ population were compared to scores for age-matched norms to investigate the burden associated with HZ.ResultsPain was prominent among patients, with 57.9% at the initial study visit reporting pain in the preceding 24 hours at levels typically considered to have a significant impact on HRQoL (i.e. ZBPI worst pain ≥ 5). This was reflected in SF-36 and EQ-5D scores that were significantly lower for patients when compared to age-matched norms (p < 0.05) - except for the SF-36 domain of physical functioning. HRQoL was inversely associated with levels of reported pain, with those patients in the greatest amount of pain reporting the greatest HRQoL impact. However, there was no association between pain severity and participant age. The majority of patients (69.4%) received antivirals within 72 hours of rash appearing and 69.9% of patients were also taking analgesics for the management of HZ pain. TSQM scores indicated that patients were least satisfied with the effectiveness of their prescribed treatment.ConclusionsThe acute presentation of HZ is a painful experience that can have a significant impact on the physical and mental wellbeing of sufferers. Findings highlight significant unmet need among patients, particularly in terms of the effectiveness of therapies for the management of HZ.

BackgroundPost-herpetic neuralgia (PHN) is the most common complication of herpes zoster (shingles). As a chronic condition, PHN can have a substantial adverse impact on patients’ lives. However, UK-specific data concerning the burden of PHN on individual patients, healthcare systems and wider society, are lacking. As the first UK-wide cross-sectional study of its kind, The Zoster Quality of Life (ZQOL) study was designed to address these concerns.MethodsPatients (n = 152) with a confirmed diagnosis of PHN (defined as pain persisting ≥ 3 months following rash onset) and aged ≥50 years were recruited from primary and secondary/tertiary care centres throughout the UK. All patients completed validated questionnaires, including the Zoster Brief Pain Inventory (ZBPI), the Medical Outcomes Study Short-Form 36 (SF-36), the EuroQol-5 Dimensions (EQ-5D) and the Treatment Satisfaction with Medication (TSQM) questionnaire. Where available, mean patient population scores on these questionnaires were compared to scores derived from age-matched normative samples to quantify the burden associated with PHN.ResultsDespite numerous consultations with healthcare professionals and receiving multiple medications for the management of their PHN, the majority of patients reported being in pain ‘most of the time’ or ‘all of the time’. A total of 59.9% (n = 91) of all PHN patients reported pain in the preceding 24 hours to assessment at levels (ZBPI worst pain ≥ 5) typically considered to have a significant impact on Health Related Quality of Life (HRQoL). Accordingly, scores for SF-36 and EQ-5D indicated significant deficits in HRQoL among PHN patients compared to age-matched norms (p < 0.05) and patients reported being dissatisfied with the perceived efficacy of therapies received for the management of PHN. Increased pain severity was observed among older participants and higher levels of pain severity were associated with greater HRQoL deficits.ConclusionsThe inadequate relief provided by PHN therapies available in the UK is associated with a significant burden among PHN patients in terms of pain severity and deficits in HRQoL which may persist for years. Therefore, alternative means such as prevention of shingles and PHN, are essential for reducing the impact on individual patients, healthcare systems and society as a whole.

BackgroundHerpes zoster (HZ) or “shingles” is common in persons aged 50 years or over. HZ is characterised by a painful dermatological rash which typically resolves in approximately one month. Persistent pain for months or years after rash onset, however, is a common complication of HZ; referred to as post-herpetic neuralgia (PHN). Both HZ and PHN have a significant impact on patients’ lives, with considerable implications for healthcare systems and wider society. The aim of the present review is to provide comprehensive documentation and critical appraisal of published data concerning the humanistic, economic and societal burden of HZ in Europe.MethodsSystematic literature searches were conducted in Medline, EMBASE, PsycINFO, EconLit, HEED and CRD databases. Searches were conducted in July 2014 and restricted to articles published in the past 20 years. Articles were selected for full review by two independent researchers in accordance with predefined eligibility criteria.ResultsFrom a review of 1619 abstracts, 53 eligible articles, were identified which reported data concerning healthcare resource use (n = 38), direct costs (n = 20), indirect costs (n = 16), total costs (n = 10) and impact on health-related quality of life (HRQoL) (n = 21). Findings highlight that PHN is associated with greater impairments in HRQoL and higher costs of management than HZ. For both HZ and PHN, pain severity is a significant predictor of impact on individuals, healthcare systems and society. While the incidence of HZ and PHN increase with age, age does not appear to be a key driver of overall costs for HZ and PHN. Specifically, while direct costs (e.g. GP, specialists, medications, hospitalisations) tend to be higher for older patients, indirect costs (e.g. work time missed) are higher for younger patients.ConclusionsAvailable evidence highlights that HZ and PHN result in significant humanistic and economic burden for patients, healthcare systems and wider societies. A tendency to focus upon healthcare resource use and the direct costs of management at the expense of other impacts (e.g. informal caregivers and formal social care) may result in an underestimation of the true burden of HZ and PHN.
