An interim report of health needs assessment of asylum seekers in Sunderland and North Tyneside.

A health needs assessment questionnaire was developed and administered to 397 asylum seekers, 291 males and 106 females, in Sunderland and North Tyneside in the North East of England. The data from the questionnaires were analysed using SPSS Version 10. Individuals retained a copy of their own questionnaire to be used as a hand held record. There was much heterogeneity of country of origin, culture, religion and previous employment and language backgrounds within the sample. A range of health needs was identified which has implications for healthcare provision. Vaccination rates were low as was screening for tuberculosis and cervical cancer. Many asylum seekers identified symptoms related to mental health and requested help in this area. Access to dental treatment was an area of high priority for many respondents.

Factors affecting the use of dietetic services by patients with diabetes mellitus.

AIMS: Dietary counselling is vital for patients with diabetes, yet many do not access professional advice. This study investigated the use of dietetic services by patients with diabetes within Sunderland Health District. METHODS: Diabetic patients were identified from the laboratory module of the Hospital Information System (HIS). Eight thousand five hundred and ninety-seven patients were identified, and cross referenced to dietetic records, producing a comprehensive database for analysis. RESULTS: Only 58.8% of the sample had dietetic records. Those with records were more likely to be: older (63.8 vs. 61.7 years, P < 0.01); male (52.6% vs. 46.8%, P < 0.05); accessing hospital diabetes services (P < 0.001); to have lipids and renal function checked (both P < 0.001); and to have poor blood glucose control (HbA(1c) > 7.5% to 58.7% vs. 29.9%, P < 0.001). Frequent attenders were most likely to be women, those with poor control, and those with shorter duration of diabetes (P < 0.001). In a logistic regression model, duration of diabetes, insulin treatment, obesity and hyperlipidaemia were the main determinants of increased use. CONCLUSIONS: This study confirmed that many patients with diabetes do not make use of professional dietetic services, and has highlighted some of the routinely documented characteristics that are associated with use of dietetic services. There appears to be scope to improve uptake of dietetic services by patients with diabetes, and to investigate further individual factors that affect access and attendance.

Low-impact falls: demands on a system of trauma management, prediction of outcome, and influence of comorbidities.

BACKGROUND: Falls from a low height are an extremely common source of injury, the severity of which is often underestimated. As a result, low fall patients are usually not transferred to Level I trauma centers. There are surprisingly few systematic data relating to the demands made on systems of trauma care by patients with low falls. This study addresses this issue using information from a comprehensive national trauma database. The performance of TRISS methodology, and the factors associated with prolonged hospital stay, in low fall patients is also examined. METHODS: The study included 31,419 patients. Patients with low falls (< 2 m) were compared with those suffering high falls (> or = 2 m), motor vehicle crashes, assault, sports injuries, and a group with unclassified injuries. Probability of survival was estimated using TRISS, and its performance in different types of injury was assessed using measures of discrimination and calibration. The influence of coexistent medical conditions on mortality and length of stay was investigated using logistic regression. RESULTS: Low falls accounted for 45.5% of all admissions, and 43.9% of the total bed days. The low fall group was older (mean age, 61.6 years), and predominantly female (62.5%) in contrast to the other groups (both p < 0.001). There were fewer severely injured patients than in all of the other groups except sports injuries. The area under the receiver operating characteristic curve for TRISS applied to low falls (0.874) was less than that for high falls (0.969), motor vehicle crashes (0.973), assaults (0.960), sports (1.000), and unclassified injuries (0.965). Also, the calibration of the TRISS model was poor for patients with low falls. A logistic regression model derived from a training set of 5,000 patients gave slightly improved discrimination and markedly improved calibration when compared with TRISS. Although there was a strong relationship between the number of coexistent medical conditions and the risk of dying after a low fall, including data on comorbidities in a predictive model did not improve performance. Prolonged stay (defined as greater than the 90th centile, 23 days) was more likely in women (p < 0.005), or with advanced age (p < 0.001) or low initial calculated probability of survival (p < 0.001). Cardiovascular and central nervous system diseases and diabetes were associated with longer hospital stay (all p < 0.001). A logistic regression model using TRISS variables and comorbidity data gave poor prediction of prolonged stay. There was considerable variation in the length of stay between institutions. CONCLUSION: Patients with low falls make considerable demands on a system of trauma care. TRISS methodology performs less well in this group than with other types of injury. Chronic medical conditions are associated with increased mortality and more prolonged stay after a low fall. Between-institutional variation in length of stay was considerable and this, along with the poor performance of predictive models derived from routinely collected clinical data, make it unlikely that length of stay could be used as a measure of institutional performance. More robust audit measures for patients with low falls are required.

Pharmacist's perceptions of nurse prescribing of emergency contraception.

Proposed strategies to reduce the rate of unplanned pregnancy in the UK include widening access to hormonal emergency contraception (HEC) through nurse prescribing and over-the-counter sales by pharmacists. This article reports on the perceptions of pharmacists regarding the appropriateness of nurse prescribing of HEC drawn from a survey of pharmacists' attitudes towards HEC deregulation. A 10% sample (n = 3999) of all members of the Royal Pharmaceutical Society of Great Britain was surveyed and a response rate of 38.6% (1543 respondents) achieved. Pharmacists were asked whether or not nurses should prescribe HEC and in what capacity. In respect of the statement that: 'Nurses should not be allowed to prescribe post-coital contraception', 42% of respondents agreed while 31.6% disagreed. This indicates that pharmacists do not have a consensus view regarding nurse prescribing of HEC. Arrangements for pharmacists prescribing under protocol received the support of 60.2% of respondents, whereas 41% expressed support for nurse prescribing under protocol. There was also relatively little support for 'specifically trained' nurses prescribing HEC. The findings are considered in relation to the development of a coherent and accessible provision of HEC and the wider implications for interprofessional relationships concerning prescribing.

Pharmacists' concerns and perceived benefits from the deregulation of hormonal emergency contraception (HEC).

OBJECTIVE: To ascertain pharmacists' views, assess willingness for involvement and delineate individual perceived competence in the supply of deregulated hormonal emergency contraception (HEC). DESIGN: Cross-sectional postal questionnaire utilising closed, open and Likert-scale questions. SUBJECTS: Three thousand nine hundred and ninety-nine registered pharmacists abstracted from the mailing list of the Royal Pharmaceutical Society of Great Britain. RESULTS: In total 1543 (38.6%) questionnaires were returned and analysed. Overall 1165 (75.5%) of pharmacists stated their willingness to be involved in the deregulated supply of HEC. However, pharmacists identified the need for specific training before effective deregulation should take place. Overall, 616 (39.9%) of respondents felt individually competent to supply deregulated HEC with a positive association between perceived competence and willingness to supply deregulated HEC (p < 0.05). Pharmacists perceive the major benefits of deregulation to be a reduced unwanted pregnancy rate and a subsequent reduced abortion rate. They perceive that deregulation would allow quicker and less restricted access to HEC by clients, facilitating an increased overall supply of HEC. Pharmacists express a number of concerns, tempering their collective desire to see HEC deregulation. The majority of these concerns related to safeguarding clients and the possible adverse public health effects associated with the possible reduced use of barrier methods of contraception. CONCLUSIONS: Most pharmacists would be willing to supply HEC if it were deregulated to 'pharmacy only' from 'prescription only' medicine status. Although concerns were raised, these were mainly related to safety issues, with few pharmacists identifying moral and ethical barriers to deregulation. For effective deregulation to occur issues of professional competence need to be addressed.

Dermatoglyphics in Darier's disease.

Palmar and fingerprints were taken from 70 patients with Darier's disease and 409 normal controls. The dermatoglyphic characteristics of each group were determined and comparisons were made between them. Dermatoglyphic abnormalities were found; some confirmed previous findings and some were novel, but they are too small in degree and frequency to be of use diagnostically.

Juvenile rheumatoid arthritis.

Musculoskeletal problems account for the majority of initial complaints attended to by primary care physicians. It is likely that a child who eventually has juvenile rheumatoid arthritis diagnosed will initially be evaluated by a family physician or a pediatrician. Primary care physicians will play an increasingly important role in management of juvenile rheumatoid arthritis, as the availability of specialists in many communities is limited, and access to them may be further limited by managed care initiatives. This article offers a brief review of the definition and classification of juvenile rheumatoid arthritis and introduces a diagnostic algorithm to provide a simplified approach toward evaluating children with arthritis. Treatment and outcomes are summarized in text and graphic formats.
