Inequalities in hospital admission rates for unintentional poisoning in young children.

OBJECTIVE: To determine the relationship between deprivation and hospital admission rates for unintentional poisoning, by poisoning agent in children aged 0-4 years. DESIGN: Cross sectional study of routinely collected hospital admissions data. SETTING: East Midlands, UK. PARTICIPANTS: 1469 admissions due to unintentional poisoning over two years. MAIN OUTCOME MEASURE: Hospital admission rates for unintentional poisoning. Incidence rate ratios (IRRs) comparing hospital admission rates for poisoning in the most and least deprived electoral wards. RESULTS: Children in the most deprived wards had admission rates for medicinal poisoning that were 2-3 times higher than those in the least deprived wards (IRR 2.49, 95% CI 1.87 to 3.30). Admission rates for non-medicinal poisoning were about twice as high in the most compared to the least deprived wards (IRR 1.77, 95% CI 1.19 to 2.64). Deprivation gradients were particularly steep for benzodiazepines (IRR 5.63, 95% CI 1.72 to 18.40), antidepressants (IRR 4.58, 95% CI 1.80 to 11.66), cough and cold remedies (IRR 3.93, 95% CI 1.67 to 9.24), and organic solvents (IRR 3.69, 95% CI 1.83 to 7.44). CONCLUSIONS: There are steep deprivation gradients for admissions to hospital for childhood poisoning, with particularly steep gradients for some psychotropic medicines. Interventions to reduce these inequalities should be directed towards areas of greater deprivation.

Randomised controlled trial of an occupational therapy intervention to increase outdoor mobility after stroke.

OBJECTIVE: To evaluate an occupational therapy intervention to improve outdoor mobility after stroke. DESIGN: Randomised controlled trial. SETTING: General practice registers, social services departments, a primary care rehabilitation service, and a geriatric day hospital. PARTICIPANTS: 168 community dwelling people with a clinical diagnosis of stroke in previous 36 months: 86 were allocated to the intervention group and 82 to the control group. INTERVENTIONS: Leaflets describing local transport services for disabled people (control group) and leaflets with assessment and up to seven intervention sessions by an occupational therapist (intervention group). MAIN OUTCOME MEASURES: Responses to postal questionnaires at four and 10 months: primary outcome measure was response to whether participant got out of the house as much as he or she would like, and secondary outcome measures were response to how many journeys outdoors had been made in the past month and scores on the Nottingham extended activities of daily living scale, Nottingham leisure questionnaire, and general health questionnaire. RESULTS: Participants in the treatment group were more likely to get out of the house as often as they wanted at both four months (relative risk 1.72, 95% confidence interval 1.25 to 2.37) and 10 months (1.74, 1.24 to 2.44). The treatment group reported more journeys outdoors in the month before assessment at both four months (median 37 in intervention group, 14 in control group: P < 0.01) and 10 months (median 42 in intervention group, 14 in control group: P < 0.01). At four months the mobility scores on the Nottingham extended activities of daily living scale were significantly higher in the intervention group, but there were no significant differences in the other secondary outcomes. No significant differences were observed in these measures at 10 months. CONCLUSION: A targeted occupational therapy intervention at home increases outdoor mobility in people after stroke.

Age and proximity to death as predictors of GP care costs: results from a study of nursing home patients.

This paper reports the results of a study of GP costs associated with a group of nursing home patients who died at various stages during a 12-month period. The relationship between costs per month of care, patient age and proximity to death, where sex and diagnosis are controlled for are reported. A comparison of care costs for patients in their last year of life and those who survived the course of the study is also made. The study found that those in their last year of life were significantly more expensive to care for than those who survived the duration of the study, but that there was no statistically significant difference in age. In multivariate regression analyses, it was also found that among those who died during the study care costs were unrelated to age, but significantly related to proximity to death. The study supports the contention of others (Zweifel P, Felder S, Meiers M. Ageing of population and health care expenditure: a red herring? Health Econ 1999; 8: 485-496) that health care costs are more directly related to proximity to death than age.

Is there a role for computerized decision support for drug dosing in general practice? A questionnaire survey.

OBJECTIVE: To determine: (i) whether general practitioners have difficulty with drug dosing; (ii) what information sources they currently use to help them with drug dosing; (iii) their views on the potential value of decision support software for drug dosing. DESIGN: Questionnaire survey. SETTING: Nottingham, U.K. PARTICIPANTS: 263 general practitioners (GPs). RESULTS: The response rate was 78% (263/336). Most GPs reported difficulties with drug dosing for children, the elderly and patients with renal impairment. Compared with 'patients in general', GPs had particular difficulties in drug dosing for these specific groups (P < 0.001). Paper-based formularies were the most common source of information for help with drug doses. Nevertheless, most GPs had positive views on the potential usefulness of computerized decision support. CONCLUSION: GPs commonly have problems in drug dosing for certain groups of patients. The development and use of computerized decision support might help GPs in these situations.

The impact of nursing home patients on general practitioners' workload.

BACKGROUND: Although the number of people in nursing homes has risen substantially in recent years, the shift of responsibility into general practice has rarely been accompanied by extra resources. These patients may be associated with a higher general practitioner (GP) workload than others of similar age and sex. AIM: To assess the GP workload associated with nursing home residents and its associated costs. METHOD: All nursing home residents aged over 65 years and registered with nine Nottinghamshire practices during one year were matched with patients living in the community for general practice, age, and sex. Data were collected retrospectively for both groups on key workload measures. Costs for the workload measures were calculated using published estimates. RESULTS: Data were collected for 270 pairs of patients. Nursing home patients had more face-to-face contacts in normal surgery hours, telephone calls, and out-of-hours visits. The mean workload cost per month of a nursing home patient (assuming that one patient was seen per visit) was estimated to be 18.21 Pounds (10.49 Pounds higher than the cost of controls). A sensitivity analysis demonstrated that potential savings in visiting costs associated with increasing the numbers of patients seen per visit were 27% for one extra patient seen per visit and 44% for four extra patients. CONCLUSION: Nursing home residents were associated with higher workload for GPs than other patients of the same age and sex living in the community. Our costings provide a basis for negotiating suitable reimbursement of GPs for their additional work.

Variations in GP nursing home patient workload: results of a multivariate analysis.

The number of old people living in UK nursing homes has increased substantially over the past 15 y. There is evidence that such patients generate larger workloads for primary carers than do those of similar age and sex living in their own homes. Clearly, any extra workload involved in providing primary care services to nursing home patients, needs to be reflected in the resources afforded general practitioners (GPs) who are tasked with its provision. By the same token variations in workloads between patients need to be examined and explained for any insights these might provide on funding issues. To examine and explain variations in GP workload associated with nursing home patients and determine the implications of these for GP funding, a 12 month case control study of all nursing home residents over 65 y old registered with nine general practices was undertaken. A multivariate regression analysis was used to examine variations in GP workload associated with 270 nursing home patients. Multivariate regression models explaining the variation in workload cost per month in terms of the GP practice delivering care and patients age and sex had little explanatory power (R(2)=0.07). A fuller method including the patient's Barthel score and initial diagnosis as additional explanatory variables added little to the explanatory power of the model (R(2)=0.12). The ability of the multivariate models used here to explain the variation in GP workload was poor. GPs may require an allowance to compensate for differences in workload associated with nursing home patients but adjusting these payments for differences in age, sex, initial diagnosis or the other variables included in this analysis would not appear to be supported.

Explaining variations in prescribing costs: results from a comparison of nursing home patients with matched pairs living in the community.

OBJECTIVES: To examine and explain variations in prescribing costs associated with nursing home patients and patients matched by age and sex living in the community. DESIGN: A 12-month case control study. SUBJECTS: All nursing home residents over 65-years-old registered with nine general practices and patients matched with them for age and sex living in the community. METHOD: Multivariate regression analysis of variations in monthly GP prescribing costs. RESULTS: Multivariate regression models explaining cost variations in terms of the GP practice delivering care and patients' age and sex had little explanatory power (R(2)=0.07 for nursing home patients, R(2)=0.03 for matched pairs). A fuller model for nursing home patients only, incorporating the patient's Barthel score and initial diagnosis as additional explanatory variables, added little to the explanatory power of the model (R(2)=0.16). CONCLUSION: The ability of the multivariate models used here to explain variations in prescribing costs among a group of elderly patients is poor. Adjusting weighted capitation formulae with respect to older patients to take account of such information or referring to it in negotiations on prescribing budgets would not appear to be warranted.

What problems do patients present with outside normal general practice surgery hours? A prospective study of the use of general practice and accident and emergency services.

BACKGROUND: This study was designed to address some current issues concerning the use of general practice and accident and emergency (A & E) services outside normal surgery hours. METHOD: Six general practices in Nottingham (with a combined population of 46,698 patients) were recruited to take part in the study. Over a six month period, data were collected on patient contacts with general practice services and the local A & E department outside normal surgery hours. RESULTS: General practice services dealt with 63 per cent of first contacts over the course of the study. There were 3181 (136 per 1000 patients per year) contacts with general practitioners and deputizing service doctors (of which 1009 (31.7 per cent) were dealt with by telephone alone) and 1876 (80 per 1000 patients per year) attendances at the A & E department. There were marked differences in the distribution of problems that patients presented to the two types of service. The proportion of presentations dealt with by telephone alone by general practice services varied with the type of presentation. However, the use of the telephone was not particularly high, even for problems such as a sore throat. CONCLUSIONS: Given the differences in presentations to both general practice and A & E services there may be limited scope for altering patients' consulting patterns without making significant changes to service provision. However, there may be scope for increasing the proportion of general practice contacts dealt with by telephone alone.

Changes in the role of general practitioners in child health surveillance.

BACKGROUND: Changes in their Contract in 1990 gave general practitioners the opportunity to become more involved in child health surveillance. This study aimed to describe and compare child health surveillance services provided by general practitioners before and after the changes of the 1990 GP contract. METHODS: A questionnaire was sent to all general practices within the Nottingham Health Authority area in 1990, and this process was repeated in 1994, ascertaining the services provided for child health surveillance. Outcome measures were: the reported provision of services, keeping of records and facilities for following up non-attenders. Also recorded were the training and qualifications of general practitioners and their attitudes towards child health surveillance. RESULTS: Response rates were 62% in 1990 and 80% in 1994. More practices were involved in the provision of child health surveillance services in 1994, more held a baby clinic and more reported having a recall system for non-attenders. There was little change in the training or qualifications of GPs in child health between 1990 and 1994. In 1994, there was evidence of GPs meeting regularly with Health Visitors. There remained a small number of practices who were not interested in child health surveillance. CONCLUSION: The 1990 GP contract appears to have increased the provision of child health surveillance services by GPs and improved liaison with Health Visitors in general practice.

Problems found in the over-75s by the annual health check.

BACKGROUND: Research into the health of elderly people has found problems unknown to their general practitioners. It was anticipated that annual checks, as required by the 1990 general practitioner contract, would help to detect these problems, yet the value of these checks has been questioned. AIM: To investigate the problems found by general practice contractual annual checks of the over-75s and the consequent actions taken; to identify patient, demographic or practice characteristics associated with the discovery of problems. METHOD: In 40 practices, information was collected on patients over 75 years of age receiving a health check during a 3-month period. Practices used their normal methods of recruitment and assessment. Practice staff were interviewed to find how assessments were organized. RESULTS: Practices saw a mean of 12% of their over-75s during the study; 44% were found to have at least one problem. Action was taken to help resolve problems in 82% of patients with a problem. The most prevalent problems related to physical condition, and fewer functional problems than expected were found. There were large differences between practices in the proportions of elderly patients seen for a check and the proportion found to have problems; these were not attributable to practice size or demography. Multivariate analysis showed that practice or patient characteristics were poor predictors of finding problems. CONCLUSION: The argument in favour of conducting annual checks is supported by the finding that nearly half the patients assessed were found to have problems for which some action was taken. Some practices could increase their rate of uptake by modifying the organization of invitations for checks. More problems may be found by adopting a more functionally based assessment.

General practice health checks of elderly people: a county-wide survey.

All general practices in Nottinghamshire were sent a questionnaire to examine the organisation and structure of their annual health checks for elderly people. The results indicated that 99% of responding practices offered checks, yet nearly one quarter estimated that under 50% of their elderly population actually had a check. Many practices had no system for following up old people who did not respond to an invitation for a check. Practices with smaller numbers of elderly people were more likely to estimate high response rates to invitations for a check and more likely to follow-up those who did not respond. The findings are discussed in relation to the reasons why many elderly people do not receive their annual health check.

Health checks on patients 75 years and over in Nottinghamshire after the new GP contract.

OBJECTIVE: To investigate annual health checks for patients of 75 years and over required by the 1990 contract for general practitioners. DESIGN: Visits to practices to collect information on how assessments were organised and carried out; completion of questionnaires for every patient who had been assessed in a sample month, using information provided by the practice records. SETTING: 20 general practices in one family health services authority. SUBJECTS: Patients of 75 years and over in 20 general practices. RESULTS: Three practices (15%) had not performed checks. Thirteen practices sent a letter to invite patients to undergo a check. Of these practices, seven followed up non-responders. Two practices visited patients' homes unannounced, and two did checks on an opportunistic basis only. Sixteen practices used a checklist. Sixteen practices involved their practice nurses; at eight of these, doctors also performed checks; in six practices the nurses undertaking the checks had no training in assessing old people. Ten practices assessed more than 75% of their old people in the first year of the new contract. Practices that did not follow up patients who had not responded to the invitation for assessment completed significantly fewer checks. During the sample month, 331 patients were assessed in the 17 practices. 204 new problems were discovered in 143 patients. Significantly more problems per patient were found in inner city areas. CONCLUSIONS: The way health checks were performed varied greatly, both in their organisation and the practices' attitudes. Many old people did not respond to letters asking if they wanted an assessment but very few refused one if followed up. Forty three per cent of those assessed had some unmet need. The number of new problems found per patient may reduce over the next few years if the assessments are successful. The need for annual assessment should be kept under review and adequate resources made available for the needs uncovered. Improved training for practice nurses in assessment is needed. Effectiveness of the checks must be monitored. If most unmet need falls in particular high risk groups it would seem sensible to modify the annual check to target these groups.

Residents of private nursing homes and their care.

A study was undertaken to examine the characteristics of residents in private nursing homes, to measure residents' dependency levels, to determine the adequacy of procedures for admitting new residents and to explore general practitioners' work with residents. Details were obtained of 61 nursing homes registered by Nottingham district health authority and of a selection of residents. Information about residents provided by the nurses in charge included aspects of self care, orientation and social integration, these items contributing to a dependency score for each resident. General practitioners completed postal questionnaires. Information was sought on the numbers of residents on the general practitioners' lists, visiting patterns, and opinions on their work with residents. It was found that almost half of the reports accompanying residents on admission were considered inadequate by the nurses in charge. The 357 residents varied widely in dependency level, need for nursing care and medication; 31% had low dependency scores. Most of the residents (57%), had been admitted from hospital, 26% from their own home and 15% from other nursing or residential homes. Higher overall dependency levels, problems with mobility and continence and need for care of wounds, catheters or colostomies were more frequent in residents admitted from hospital or nursing or residential homes than in those admitted from their own home. The 70 responding general practitioners varied widely in the numbers of residents on their lists and in their visiting patterns. The 16 general practitioners providing medical care for entire nursing homes were significantly more likely than the other general practitioners to visit routinely.(ABSTRACT TRUNCATED AT 250 WORDS)

Reproducibility and accuracy of pulmonary artery pressure measurement in supine and lateral positions.

The reproducibility and accuracy of pulmonary artery (PA) pressures in supine versus side-lying positions were compared in two groups of intensive care unit (ICU) patients. Side-lying measurements were reproducible, accurate, and clinically acceptable for surgical ICU patients, but not for medical ICU patients. The inconsistency was partly explained by the reference points used for transducer releveling in lateral positions. Surgical ICU used the fourth intercostal space and dependent midaxillary line; medical ICU used the fourth intercostal space and sternum. Reversing the leveling procedure in each ICU reduced surgical unit accuracy to an unacceptable level; medical unit accuracy was increased but was still too low for clinical acceptance. Further research is needed to identify appropriate anatomic reference points for transducer releveling in the side-lying position and to clarify which patient groups may be safely monitored by using this position.

Injectate temperature: effects on thermodilution CO measurements.

The present study has confirmed the findings of other research and indicates that current technology permits accurate CO determination using room temperature injectate. Some patients, especially those with high output, temperature, or blood pressure, may continue to require iced injectate measures to ensure accuracy; more research is needed here. Room temperature measures may be less reproducible than iced. Several ways of compensating for this have been suggested, depending on the technology available. At present, these methods are preferable to using a correction formula based on regression analyses.
