The assessment of need for mental health services.

BACKGROUND: The field of psychiatric epidemiology has yielded several large and important studies of the prevalence of psychiatric disorders. These surveys have been enhanced by the inclusion of methodologies that reflect the needs for care of the population in question. Clinical studies of psychiatric disorders and unmet needs have focussed on identifying needs and correlating them with service evaluation and satisfaction measures. The association between prevalence, service use and unmet need requires review in order to establish whether there are trends and consistent findings. METHOD: Peer-reviewed studies involving the assessment of need up to the present were included. These were of two broad groups: population-based studies and clinical studies. Studies based on outcome measures, review articles, and child psychiatry, old age, and intellectual disability samples were excluded. We conducted a search of MEDLINE and PSYCHINFO using the key words, "mental health needs","assessment of need", and "needs assessment". In addition, we hand-searched key journals and sought personal communication with researchers in the field. RESULTS: A total of 14 population studies and 19 clinical studies were retrieved. The percentage of the general population who reported at least one need for care ranged from 9.5% to 13.8%. The numbers of needs in psychiatric patients ranged from 3.3 to 8.6. Correlates of unmet need include: unemployment, single status, low quality of life and high disability scores, and the presence of certain psychiatric diagnoses, such as affective psychosis and personality disorders. Higher rates of met need and service satisfaction are correlated with a longer duration of service contact. CONCLUSION: The assessment of need to date has been established either by service use data to make inferences about unmet need, by asking limited guided questions about needs, or by using established needs assessment instruments. The high prevalence of psychiatric disorders and the weak correlation between disorder and unmet need require a combined approach towards service development.

Adjustable vs set-pressure valves decrease the risk of proximal shunt obstruction in the treatment of pediatric hydrocephalus.

INTRODUCTION: The use of programmable shunt valves has increased dramatically in the practice of pediatric hydrocephalus. Despite theoretical advantages, it remains unclear if the use of programmable vs set-pressure valves affects shunt outcome. MATERIALS AND METHODS: The clinical and radiological records of all pediatric patients undergoing ventriculoperitoneal (VP), ventriculopleural (VPl), and ventriculoatrial (VA) shunt surgery from 2001 to 2004 at an academic institution were reviewed. The association of programmable vs set-pressure valves with subsequent shunt revision was assessed by Kaplan-Meier shunt survival plots and log-rank analysis. RESULTS: A total of 279 VP, VPl, and VA shunt surgeries were performed on patients with median (interquartile range) age of 4 (1-14) years (161 male, 118 female; 158 communicating, 122 obstructive hydrocephalus). Programmable valves were used in 76 (27%) cases and set-pressure valves in 203 (73%). At mean+/-SD follow-up of 17 +/- 13 months, programmable vs set-pressure valves were associated with reduced risk of both overall shunt revision [26 (35%) vs 109 (54%); relative risk (RR) (95% CI); 0.61 (0.41-0.91), p = 0.016] and proximal obstruction [9 (12%) vs 58 (28%); RR (95% CI); 0.39 (0.27-0.80), p = 0.006]. There was no difference in distal obstruction [3 (4%) vs 11 (5%) cases], infection [6 (8%) vs 12 (6%) cases], valve obstruction [0 (0%) vs 4 (2%)], or shunt disconnection [2 (3%) vs 1 (1%)] between adjustable and set-pressure valves, respectively. CONCLUSION: In our experience, the use of programmable vales was associated with a decreased risk of proximal shunt obstruction and shunt revision. Programmable valves may be preferred in patients frequently experiencing proximal shunt failure. A prospective, controlled study is warranted to evaluate the potential value of adjustable vs set-pressure valve systems.

Ligand-receptor interaction at the neural nicotinic acetylcholine binding site: a theoretical model.

Recent mutagenesis experiments have identified some of the functional amino acids that are essential in the interaction of nicotinic agents with the binding site of the neural nicotinic acetylcholine receptor (nAChR). Although this receptor is one of the best studied and characterized the lack of detailed experimental information regarding its quaternary structure has turned it into a challenge for computational chemistry. We have previously reported [J. Comput. Aided Mol. Design 13 (1999) 57-68] a computational protocol based on molecular mechanics and molecular dynamics (MD) where SER82, ASP83, TRP86, ASP89, TYR93, TYR190, TYR198 and ARG209 were placed around selected agonists and antagonists aided by stereoelectronic criteria. Explicit water molecules were used with the double goal of simulating aqueous environment and keeping the system from falling apart. The protocol was stable enough to allow the ligands to evolve to their thermodynamically most probable structure while maintaining the key interactions. In this communication we use the average model for the agonists (one average structure for each agonist) to calculate quantum mechanically the interactions of the binding site with one neurotransmitter acetylcholine (ACh, 1), as well as with two of the most potent agonists described so far [nicotine (2) and epibatidine (3)] and the modeled binding site. A wide variety of methods as well as basis sets were used in order to rationalise the best way to treat the problem. In this limited set of compounds, a good correlation between total interaction energies and biological affinity is observed.

The Short Cognitive Performance Test (SKT): a preliminary study of its psychometric properties in Brazil.

BACKGROUND: Most instruments designed to detect dementia can lack appropriate sensitivity in the early stages of Alzheimer's disease (AD), and are subject to educational bias. The Short Cognitive Performance Test (Syndrom-Kurztest, SKT) is considered a suitable instrument to measure cognitive decline as it assesses memory, attention, and related cognitive functions, taking into account the speed of information processing. OBJECTIVES: The aim of this study was to examine the psychometric characteristics of the SKT as a dementia screening instrument in a Brazilian population sample, as compared to the Mini-mental State Examination (MMSE) and the Clock-Drawing Test (CDT). The effect of educational level on performance in the three screening tests was also verified. METHODS: Fifty-one elderly subjects were assessed. Consensus diagnoses were established by an expert multidisciplinary team, considering clinical, neuropsychological and neuroimaging data. Subjects were further classified into those with (1) mild and moderate AD, (2) non-Alzheimer's dementia, (3) mild cognitive impairment, and (4) controls, according to National Institute for Communicative Disorders and Stroke--Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria. RESULTS: Statistical analyses revealed high internal consistency for the SKT (Cronbach's alpha = 0.80) and significant correlations between the total score and the SKT subscores separately (p < 0.01). Comparison of the three tests revealed strong correlations between the SKT and the MMSE (r = -0.66, p < 0.0001) and between the SKT and the CDT (r = -0.57, p < 0.0001). The SKT, MMSE and CDT scores were correlated with education. CONCLUSIONS: The Brazilian version of the SKT maintains its original psychometric properties and displays significant correlation with previously validated screening tools for dementia. Like other dementia screening tests, the SKT is subject to educational bias.

The impact of matching the patient's vocabulary: a randomized control trial.

BACKGROUND: Research in general practice emphasizes the importance of matched models, beliefs and vocabulary in the consultation. OBJECTIVE: The present study aimed to explore the impact of matched and unmatched vocabulary on patient satisfaction with consultations. METHODS: The study took place in one inner city general practice. Patients (n=62) were randomized to either matched or unmatched vocabulary consultations when consulting for problems relating to sexual or bodily function or anatomy. Matched consultations required the doctor to use the same vocabulary as the patient. Unmatched consultations required the doctor to use medical vocabulary. Completed questionnaires were received from 60 patients. The main outcome measure was patient satisfaction (using the Medical Interview Satisfaction Scale). This assesses total satisfaction and has four subscales: distress relief; communication comfort; rapport; and compliance intent. Doctor satisfaction with the consultation was also assessed. RESULTS: The results showed that the two groups were comparable for demographic variables and doctor satisfaction. However, patients in the matched consultation group had significantly higher total satisfaction scores and higher ratings of rapport, communication comfort, distress relief and compliance intent than those in the unmatched group. CONCLUSION: The results indicate that a doctor's choice of vocabulary affects patient satisfaction immediately after a general practice consultation and that using the same vocabulary as the patient can improve patient outcomes.

Occupational titles as risk factors for Parkinson's disease.

BACKGROUND: Job title or employment sector may be associated with Parkinson's disease (PD). METHODS: In a case-control study, in four European centres, lifetime occupational histories were coded using modified International Standard Industrial Classification (ISIC) and Dictionary of Occupational Titles (DOT). We employed multiple logistic regression analyses adjusting for age, gender, smoking and family history of PD. RESULTS: A total of 649 cases and 1587 controls were recruited. Scottish data showed a non-significant increased risk for agriculture (DOT: OR 1.32, 95% CI 0.81-2.16; ISIC: OR 1.30, 95% CI 0.84-2.02) and reduced risk for 'transport and communication' (ISIC: OR 0.60, 95% CI 0.37-0.97). Subsequent four-centre analyses showed reduced risk for processing occupations (DOT: OR 0.69, 95% CI 0.5-0.95). An association with pesticide exposure, found using detailed exposure assessment, was not apparent using job classification. CONCLUSIONS: In contrast to retrospective exposure assessment, job or industrial sector is a weak indicator of toxic exposures such that true associations may be missed.

Fish intake during pregnancy and early cognitive development of offspring.

BACKGROUND: Fish is a source of many nutrients that can be beneficial during pregnancy, as well as a source of neurotoxicant contaminants such as methylmercury. Previous investigations of fish intake in relation to neurodevelopment have focused on possible damage from contaminants, whereas potential benefits of fish consumption have been relatively unexplored METHODS: We evaluated the association between maternal fish intake during pregnancy and offspring's early development of language and communication skills in a cohort of 7421 British children born in 1991-1992. Fish intake by the mother and child was measured by questionnaire. The child's cognitive development was assessed using adaptations of the MacArthur Communicative Development Inventory at 15 months of age and the Denver Developmental Screening Test at 18 months of age. Mercury was measured in umbilical cord tissue for a subset of 1054 children RESULTS: Total mercury concentrations were low and were not associated with neurodevelopment. Fish intake by the mother during pregnancy, and by the infant postnatally, was associated with higher mean developmental scores. For example, the adjusted mean MacArthur comprehension score for children whose mothers consumed fish 4 or more times per week was 72 (95% confidence interval = 71-74), compared with 68 (66-71) among those whose mothers did not consume fish. CONCLUSIONS: When fish is not contaminated, moderate fish intake during pregnancy and infancy may benefit development.

Evolution of wrinkles in hard films on soft substrates.

A compressively strained film on a substrate can wrinkle into intricate patterns. This Rapid Communication studies the evolution of the wrinkle patterns. The film is modeled as an elastic nonlinear plate and the substrate a viscoelastic foundation. A spectral method is developed to evolve the nonlinear system. When the initial film strains are isotropic, the wrinkles evolve into a pattern with a motif of zigzag segments, in random orientations. When the initial film strains are anisotropic, the wrinkles evolve to an array of herringbones or stripes. The zigzag segments select a width, a length, and an elbow angle that minimize the total elastic energy.

Incidence and clinical features of acute inflammatory polyradiculoneuropathy in Lombardy, Italy, 1996.

OBJECTIVE: To assess the annual incidence of typical Guillain-Barré syndrome (GBS) and its main variants (atypical GBS) in a well-defined population from a large area. MATERIAL AND METHODS: A population-based prospective survey of GBS was undertaken during the calendar year 1996 in Lombardy, Italy (population 8,891,652). Typical and atypical GBS was diagnosed using the National Institutes of Neurological and Communicative Disorders and Stroke (NINCDS) and Ropper criteria. Eligible cases were hospital inpatients traced through a regional registry, the hospital discharge diagnoses, and an ongoing case-control study. Diagnostic and demographic findings were collected for each case. Complete clinical and laboratory features were available for 80% of cases. RESULTS: A total of 138 patients (males 74; females 64) aged 2-91 years fulfilled the diagnostic criteria for typical GBS (128) or atypical GBS (10). GBS variants included Miller-Fisher syndrome (four cases), cranial polyneuritis (three cases), pure motor GBS (two cases), and sensory loss with areflexia (one case). The crude annual incidence of GBS was 1.55 per 100,000 (typical GBS 1.43; atypical GBS 0.11; male 1.67; female 1.43; age <35 years, 0.79; 35-54 years, 1.33; 55-74 years, 3.22; 75+ years, 4.67). The overall rate was 1.58 when age- and sex-adjusted to the 1996 Italian population. Previous infections were reported for 37% of patients. The electrophysiological findings indicated demyelination in 51%, primary axonopathy in 14%, and mixed myelin and axon involvement in 27%. CONCLUSIONS: The incidence of typical GBS is comparable with that in other reports using the NINCDS diagnostic criteria. Atypical GBS accounts for a limited number of cases.

Radiology by nonradiologists: is report documentation adequate?

OBJECTIVE: To determine if the quality of medical imaging reports differs significantly between radiologists and nonradiologists. STUDY DESIGN: A retrospective nonblinded review of randomly selected chest and long bone x-ray reports by orthopedists and primary care physicians compared with randomly selected imaging reports generated by radiologists. METHODS: We randomly selected 1 report from each of 50 high self-referring physicians privileged by 2 metropolitan New York area health plans for both bone and joint studies and chest x-rays for a total of 200 reports (50 bone and joint x-rays from each plan and 50 chest x-rays from each plan). We compared them with 50 randomly selected radiologist-generated reports. The reports were evaluated for quality based on the American College of Radiology's Guideline for Communication: Diagnostic Radiology. The data were analyzed by the 2-sample t-test between proportions at the 95% confidence interval. RESULTS: Radiologists consistently provided higher-quality medical imaging reports than nonradiologists. CONCLUSIONS: To improve imaging service quality, all providers should be held to the same standards for reporting and communication of results.

[Quality evaluation from the patient viewpoint--exemplary results from the European WHO Project "Health-Promoting Hospitals"].

This article has two objectives: first of all, to present the European WHO project "Health Promotion in Hospitals" in a general way and secondly, to report on results of empirical concomitant research on a sub-project on quality assessment from the patient's viewpoint in a Hamburg member hospital of the international WHO pilot project and to present the essential partial aims of this approach to health promotion. An interim report on the international pilot project showed clearly that among all the realisation projects those are the most frequent ones that aim at promoting the health of patients (87 of a total 181). We report on one of these projects (partly sponsored by the North German Centre of Public Health). Focus is on the results of a quantitative query among patients (n = 157 = 58% response rate). The methods on which the study is based as well as the relevant limitations of its representative nature are outlined. Essential results quoted are the assessments made by the patients themselves taking into consideration 11 dimensions of hospital quality. It becomes evident that action should be taken in the area of several communicative dimensions and in hospital facilities. The results of the inquiry provided the basis for hospital quality improvements. An internal project group within the hospital worked out recommendations that have since been translated into reality to a large extent.

Female sexuality and sexual dysfunction: are we stuck on the learning curve?

INTRODUCTION: Female sexual dysfunctions (FSDs) are very prevalent, multifaceted problems that continue to be under-recognized and undertreated. Improved recognition and management depend on physicians' inclination and ability to communicate with female patients about their sexual function. Many women hesitate to share sexual complaints due to concerns about physicians' time constraints or their interest in addressing it. Direct questioning by physicians about sexual function is often critical to patients' reporting of sexual concerns. AIM: To obtain pilot data on physicians' knowledge, perceptions, and practices regarding FSDs, which may help uncover means of facilitating future dialog between physicians and patients. METHODS: A self-reply questionnaire was used to survey physicians and other health professionals attending the 2004 annual meetings of four major specialty societies. MAIN OUTCOME MEASURES: Survey questions were included on the prevalence of FSDs; dialog on sexual function/activity; obstacles to appropriate evaluation and management of FSDs; effectiveness of current treatment options; and referral patterns. RESULTS: A total of 1,946 attendees completed the survey. Most respondents (60%) estimated that one- to three-quarters of their patients had FSDs. Low sexual desire was the most prevalent FSD observed. A total of 58% of participants reported initiating the first discussion of FSDs in one-quarter or less of patients. Obstacles to discussing sexual health included limited time and training, embarrassment, and absence of effective treatment options. Approximately 60% of participants rated both their knowledge of and comfort level with FSDs as only fair or poor. Eighty-six percent rated current treatment options as fair or poor. CONCLUSION: Healthcare professionals are aware of the high prevalence of FSDs but infrequently initiate a discussion of sexual function with their female patients or conduct a comprehensive evaluation for FSDs. Additional medical education and training are needed to improve the identification and management of FSDs in women.

First evaluation of the NHS direct online clinical enquiry service: a nurse-led web chat triage service for the public.

BACKGROUND: NHS Direct is a telephone triage service used by the UK public to contact a nurse for any kind of health problem. NHS Direct Online (NHSDO) extends NHS Direct, allowing the telephone to be replaced by the Internet, and introducing new opportunities for informing patients about their health. One NHSDO service under development is the Clinical Enquiry Service (CES), which uses Web chat as the communication medium. OBJECTIVE: To identify the opportunities and possible risks of such a service by exploring its safety, feasibility, and patient perceptions about using Web chat to contact a nurse. METHODS: During a six-day pilot performed in an inner-city general practice in Coventry, non-urgent patients attending their GP were asked to test the service. After filling out three Web forms, patients used a simple Web chat application to communicate with trained NHS Direct triage nurses, who responded with appropriate triage advice. All patients were seen by their GP immediately after using the Web chat service. Safety was explored by comparing the nurse triage end point with the GP's recommended end point. In order to check the feasibility of the service, we measured the duration of the chat session. Patient perceptions were measured before and after using the service through a modified Telemedicine Perception Questionnaire (TMPQ) instrument. All patients were observed by a researcher who captured any comments and, if necessary, to assisted with the process. RESULTS: A total of 25 patients (mean age 48 years; 57% female) agreed to participate in the study. An exact match between the nurse and the GP end point was found in 45% (10/22) of cases. In two cases, the CES nurse proposed a less urgent end point than the GP. The median duration of Web chat sessions was 30 minutes, twice the median for NHS Direct telephone calls for 360 patients with similar presenting problems. There was a significant improvement in patients' perception of CES after using the service (mean pre-test TMPQ score 44/60, post-test 49/60; p=0.008 (2-tailed)). Patients volunteered several potential advantages of CES, such as the ability to re-read the answers from the nurse. Patients consider CES a useful addition to regular care, but not a replacement for it. CONCLUSIONS: Based on this pilot, we can conclude that CES was sufficiently safe to continue piloting, but in order to make further judgments about safety, more tests with urgent cases should be performed. The Web chat sessions as conducted were too long and therefore too expensive to be sustainable in the NHS. However, the positive reaction from patients and the potential of CES for specific patient groups (the deaf, shy, or socially isolated) encourage us to continue with piloting such innovative communication methods with the public.

An outbreak of viral gastroenteritis in a psychiatric hospital.

In September and October 1987, an outbreak of gastroenteritis due to small round structured viruses occurred in a large psychiatric hospital. A total of 149 people, 83 patients and 66 members of staff, were affected over a 26-day period. Most cases were associated with three psychogeriatric wards. The outbreak highlighted the special problems of infection control in long-stay psychiatric units and methods of overcoming these difficulties are discussed.

Monologue, dialogue, and soliloquy.

Psychoanalytical therapy can be seen along developmental lines of three phases, the phases correlating with the early mother/child relationship which is reenacted in the transference relationship. At times one or the other of the phases can be totally permanent, but there can be alternation of the various phases both within a session and between sessions. Techniques implied for therapy are outlined and discussed, as the phases are explicated and related to Rickman's one-, two-, and three-or-more-body relationships.

The study of gap junctional intercellular communication in keratinocytes as screening of promoter effect induced by industrial and environmental toxic substances.

BACKGROUND: Disordered functioning of gap junctions between normal and initiated cells has been proposed as one possible mechanism of tumour promotion. Many putative carcinogens such as peroxisome proliferators, are known to activate various signal transduction mechanisms and modulate gap junctional intercellular communication (GJIC). They act as tumour promoters on pre-existing "initiated" cells, rather than as genotoxic initiators. OBJECTIVES: The aim of this article is to provide a screening-tool to evaluate the promoter carcinogen effect of environmental and occupational chemical contaminants, focusing on their ability to alter GJIC. METHODS: GJIC was investigated in serum-free cultured primary human keratinocytes, by directly evaluating the intercellular transfer of a microinjected fluorescent dye (Dye transfer). The expression of caspase 3, which is the ultimate target to be activated of both mitochondrial- and non-mitochondrial-linked pro-apoptotic pathways, was evaluated using Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR). RESULTS: Mercury chloride (10 nM), mono-methyl Mercury (250 nM) and Trichloroethylene (500 I1M) were shown to significantly inhibit GJIC. Conversely di-methyl mercury, lead acetate and epichloridine had no effect on GJIC. All Trans Retinoic Acid completely reversed the inhibitory effect on GJIC induced by HgCI2 but not that induced by mono-methyl mercury and trichloroethylene. The result of a RT-PCR assay on total RNA cell extract showed that treatment of keratinocytes with 10 nM HgCl2 resulted in a decrease of the pro-apoptotic caspase 3 expression. CONCLUSIONS: In this work a protocol is designed to study gap junction intercellular communication in primary cultures of human keratinocytes which could be used as a reliable screening tool to test the promoter carcinogen effect of various environmental and occupational contaminants.

Trust and sources of health information: the impact of the Internet and its implications for health care providers: findings from the first Health Information National Trends Survey.

BACKGROUND: The context in which patients consume health information has changed dramatically with diffusion of the Internet, advances in telemedicine, and changes in media health coverage. The objective of this study was to provide nationally representative estimates for health-related uses of the Internet, level of trust in health information sources, and preferences for cancer information sources. METHODS: Data from the Health Information National Trends Survey were used. A total of 6369 persons 18 years or older were studied. The main outcome measures were online health activities, levels of trust, and source preference. RESULTS: Analyses indicated that 63.0% (95% confidence interval [CI], 61.7%-64.3%) of the US adult population in 2003 reported ever going online, with 63.7% (95% CI, 61.7%-65.8%) of the online population having looked for health information for themselves or others at least once in the previous 12 months. Despite newly available communication channels, physicians remained the most highly trusted information source to patients, with 62.4% (95% CI, 60.8%-64.0%) of adults expressing a lot of trust in their physicians. When asked where they preferred going for specific health information, 49.5% (95% CI, 48.1%-50.8%) reported wanting to go to their physicians first. When asked where they actually went, 48.6% (95% CI, 46.1%-51.0%) reported going online first, with only 10.9% (95% CI, 9.5%-12.3%) going to their physicians first. CONCLUSION: The Health Information National Trends Survey data portray a tectonic shift in the ways in which patients consume health and medical information, with more patients looking for information online before talking with their physicians.

Incidence and clinical significance of spontaneous intrahepatic portosystemic venous shunts detected by sonography in adults without potential cause.

PURPOSE: B-mode and color Doppler sonography were used to assess the incidence and clinical significance of spontaneous intrahepatic portosystemic venous shunt in adults without detectable cause. METHODS: A total of 25,579 adults without potential cause of intrahepatic portosystemic venous shunt were screened using B-mode sonography. Suspicion of shunt was confirmed by color Doppler sonography. Patients with shunt were followed up with sonography at 6- to 12-month intervals and received dietary education to prevent the ingestion of extra-large amounts of protein. During each sonography session, the patients were asked to report any experience of consciousness disturbance. RESULTS: Six patients (0.0235%) showed evidence of shunt on color Doppler sonography. Direct communication between a right portal branch and the inferior vena cava was found in 3 patients; a small aneurysm connecting a peripheral portal branch to the hepatic vein was found in the remaining 3 patients. Five patients were followed up (range, 12-60 months) and showed no change in the size of the shunt. None of the patients with shunt reported an experience of consciousness disturbance. CONCLUSIONS: The incidence of spontaneous intrahepatic portosystemic venous shunt is extremely low in asymptomatic adult patients. Follow-up and dietary control seen to be suitable for their management.
