Background: previous UK National Audits of Continence Care showed low rates of assessment and treatment of faecal incontinence (FI) in older people.Objective: the 2009 audit assessed adherence to the National Institute for Health and Clinical Excellence guidelines on management of FI and compared care in older versus younger patients.Methods: fifteen older (65+) and 15 younger (18–65) patients with FI were to be audited in hospital (inpatient or outpatient), primary care (PC) and care home sites.Results: data were submitted for n = 2,930 cases from 133 hospitals, n = 1,729 from 97 PC surgeries and n = 693 from 63 care homes. Bowel history was not documented in 41% older versus 24% younger patients in hospitals and 27 versus 19% in PC (both P < 0.001). In older people, there was no documented focused examination in one-third in hospitals, one-half in PC and three-quarters in care homes. Overall, <50% had documented treatment for an identified bowel-related cause of FI. FI was frequently attributed to co-morbidity. Few patients received copies of their treatment plan. Quality-of-life impact was poorly documented particularly in hospitals.Conclusions: this national audit shows deficits in documented assessment, diagnosis and treatment for adults with FI despite availability of clinical guidance. Overall care is significantly poorer for older people. Clinicians, including geriatricians, need to lead on improving care in older people including comprehensive assessment where needed. Improvement in some indicators in older people with successive audits suggests that ongoing national audit with linked information resources can be useful as both monitor and agent for change.

Varicella-zoster virus (VZV) is the causative agent of both varicella (chickenpox) and herpes zoster (HZ) (shingles). After varicella infection, the virus remains dormant in the host's dorsal ganglia and can reactivate due to waning cell-mediated immunity, causing HZ. Exposure of varicella-immune persons to VZV may boost the host's immune response, resulting in a protective effect against HZ. In this study, we used mathematical models of VZV transmission and HZ development to test the biological hypothesis of “progressive immunity,” originally proposed by Hope-Simpson (Proc R Soc Med. 1965;58:9–20), that cell-mediated protection against HZ increases after each episode of exposure to VZV. Predictions from a model incorporating such a hypothesis were compared with those of other concurrent models proposed for explaining HZ epidemiology. The progressive immunity model fits significantly better the age profile of HZ incidence for Finland (years 2000–2006), Italy (2003–2005), Spain (1997–2004), and the United Kingdom (1991–1992), suggesting that this mechanism may be critical in shaping HZ patterns. The model thus validated is an alternative to VZV models currently used to evaluate the impact of mass immunization programs for varicella and therefore extends the range of tools available to assist policy-makers with the present decision paralysis on the introduction of vaccination.

Information on dietary supplements, medications, and other xenobiotics in epidemiologic surveys is usually obtained from questionnaires and is subject to recall and reporting biases. The authors used metabolite data obtained from hydrogen-1 (or proton) nuclear magnetic resonance (1H NMR) analysis of human urine specimens from the International Study of Macro-/Micro-Nutrients and Blood Pressure (INTERMAP Study) to validate self-reported analgesic use. Metabolic profiling of two 24-hour urine specimens per individual was carried out for 4,630 participants aged 40–59 years from 17 population samples in Japan, China, the United Kingdom, and the United States (data collection, 1996–1999). 1H NMR-detected acetaminophen and ibuprofen use was low (∼4%) among East Asian population samples and higher (>16%) in Western population samples. In a comparison of self-reported acetaminophen and ibuprofen use with 1H NMR-detected acetaminophen and ibuprofen metabolites among 496 participants from Chicago, Illinois, and Belfast, Northern Ireland, the overall rate of concordance was 81%–84%; the rate of underreporting was 15%–17%; and the rate of underdetection was approximately 1%. Comparison of self-reported unspecified analgesic use with 1H NMR-detected acetaminophen and ibuprofen metabolites among 2,660 Western INTERMAP participants revealed similar levels of concordance and underreporting. Screening for urinary metabolites of acetaminophen and ibuprofen improved the accuracy of exposure information. This approach has the potential to reduce recall bias and other biases in epidemiologic studies for a range of substances, including pharmaceuticals, dietary supplements, and foods.
