An evidence-based guideline for children presenting with acute breathing difficulty.

OBJECTIVE: The aim of this study was to develop an evidence-based guideline for use primarily by junior clinicians to assist with the management of children presenting to the hospital with an acute breathing difficulty. METHODS: An overview of the literature provided a framework of clinical questions for the management of a child with an acute breathing difficulty on which to base a systematic literature review. Relevant articles were appraised by the research fellow and graded according to their quality. A national panel of 50 clinicians was provided, by post, with the clinical questions, research papers, appraisals and the grades of recommendations generated. They were asked to check the grades allocated to the recommendations and the accuracy of the language used. They were also provided with all the clinical questions for which there was insufficient evidence to reach a conclusion but for which a consensus recommendation was required. A Delphi method was used to formalise the consensus process. For all recommendations, panel members were asked to rate their level of agreement on a 1-9-point Likert scale. The results of the first round were fed back, and appropriate alterations to the recommendations made or additional recommendations included. The process of rating was repeated, and the final guideline was developed based on the consensus reached. RESULTS: Following two iterative rounds, the guideline was completed as a full technical document, with a series of key recommendations and an algorithm. It was based on 10 grade A (evidence from systematic review or meta-analyses), 5 grade B, 17 grade C and 31 grade D (consensus or expert opinion) recommendations. CONCLUSION: We have developed an evidence-based guideline that has subsequently been successfully implemented in the paediatric emergency departments and disseminated nationally. Results showing the effect of the guideline upon practice will be published separately.

The impact of presenting problem based guidelines for children with medical problems in an accident and emergency department.

AIMS: To evaluate the impact of presenting problem based guidelines in managing children with either diarrhoea (with or without vomiting) or seizure (with or without fever). METHODS: This prospective observational study with an intervention was based on a paediatric accident and emergency (A&E) department in Nottingham. All patients (either GP or self referred) were acute attenders aged 0-15 years, with a medical presenting problem during 4 months in the spring of 1997 and 1999. Five hundred and thirty-one diarrhoea attendances (292 before guideline implementation and 239 after) and 411 seizure attendances (212 before guideline implementation and 199 after) were recorded. Evidence based and consensus ratified guidelines developed for the study were implemented using care pathway documentation. Process (documentation, time in the department, investigations, treatment) and outcome (admission to hospital, returns to A&E) data were collected from case notes. RESULTS: The percentage of children investigated with blood tests fell significantly (haematology requests in diarrhoea presentations from 11% to 4%, biochemistry in seizure presentations from 29% to 17%). Intravenous infusions in diarrhoea presenters fell (9% to 1%), and more appropriate oral fluids were used. Management time in A&E was reduced (diarrhoea presenters: median of 55-40 minutes, seizure presenters: 80-55 minutes, but remained static for other presenting problems). Marked improvements in documentation were seen. Admission rates for diarrhoea attenders increased (27% to 34%) but remained the same for seizure (69% v 73%). CONCLUSIONS: The implementation of a presenting problem based guideline as a care pathway was associated with improvements in the quality of care by: improved documentation; reduced invasive investigations; more appropriate treatment, and reduced time spent in A&E.

An evidence and consensus based guideline for the management of a child after a seizure.

OBJECTIVE: An evidence and consensus based guideline for the management of the child who presents to hospital having had a seizure. It does not deal with the child who is still seizing. The guideline is intended for use by junior doctors, and was developed for this common problem (5% of all paediatric medical attenders) where variation in practice occurs. OPTIONS: Assessment, investigations (biochemistry, lumbar puncture, serum anticonvulsant levels, EEG in particular), and/or admission are examined. OUTCOMES: The guideline aims to direct junior doctors in recognising those children who are at higher risk of serious intracranial pathology including infection, and conversely to recognise those children at low risk who are safe to go home. EVIDENCE: A systematic review of the literature was performed. Articles were identified using the electronic data bases Medline (from 1966 to June 1998), Embase (from 1980 to June 1998) and Cochrane (to June 1998), and selected if they investigated the specified clinical question. Personal reviews were excluded. Selected articles were appraised, graded, and synthesised qualitatively. Statements of recommendation were made. CONSENSUS: An anonymous, postal Delphi consensus development was used. A national panel of 30 medical and nursing staff regularly caring for these children were asked to grade their agreement with the statements generated. They were sent the relevant original publications, the appraisals, and literature review. On the second and third rounds they were asked whether they wished to re-grade their agreement in the light of other panellists' responses. Consensus was defined as 83% of panellists agreeing with the statement. Recommendations in brief: For afebrile seizures all children should have their blood pressure recorded, but no other investigations are routine although a seizing or somnolent child should have blood glucose measured; all children under 1 year should be admitted. For seizures with fever, clinical signs indicating the need to treat as meningitis are given. Children should be admitted if they are under 18 months old, have had a complex seizure, or after pretreatment with antibiotics. VALIDATION: The guideline has undergone implementation and evaluation in a paediatric accident and emergency department, the results of which will be published separately. Only one alteration was made to the guideline as a result of this validation process, which is included here.

Recent trends in hospital use by children in England.

BACKGROUND: Routine hospital statistics for England appear to overestimate use of children's wards and include numbers of well newborn babies staying with their mothers after delivery ("well babies"). AIM: To review trends in use of children's wards excluding data on newborn babies. METHODS: We reviewed routine, published, and age stratified data requested from the Department of Health to identify separately "well babies" and babies receiving neonatal specialist care from admissions (surgical and paediatric) to children's wards. RESULTS: Routine reports for paediatric activity contain large numbers of "well babies", (almost half the total) as well as babies receiving specialist neonatal care. After excluding these, paediatric admissions represent 9.9% of the child population aged under 5 years each year (an additional 2.5% are admitted for surgical care). Between 1989 and 1997 paediatric admissions rose by 19% and surgical admissions fell by 25% with a plateau reached in overall child admissions. There are now fewer beds in which children stay for a shorter time and there is more day case surgery. Neonatal specialist care work has risen despite a fall in births. CONCLUSION: Categories should be established for reporting paediatric episodes on children's wards separately from those on neonatal units, with better identification of "well babies". When monitoring use of children's inpatient facilities or planning new units, care must be taken to separate paediatric data on neonatal units from work on children's wards. Children's surgical episodes should also be taken into account.

An evidence and consensus based guideline for acute diarrhoea management.

OBJECTIVE: To develop an evidence and consensus based guideline for the management of the child who presents to hospital with diarrhoea (with or without vomiting), a common problem representing 16% of all paediatric medical attenders at an accident and emergency department. Clinical assessment, investigations (biochemistry and stool culture in particular), admission, and treatment are addressed. The guideline aims to aid junior doctors in recognising children who need admission for observation and treatment and those who may safely go home. EVIDENCE: A systematic review of the literature was performed. Selected articles were appraised, graded, and synthesised qualitatively. Statements on recommendation were generated. CONSENSUS: An anonymous, postal Delphi consensus process was used. A panel of 39 selected medical and nursing staff were asked to grade their agreement with the generated statements. They were sent the papers, appraisals, and literature review. On the second and third rounds they were asked to re-grade their agreement in the light of other panelists' responses. Consensus was predefined as 83% of panelists agreeing with the statement. RECOMMENDATIONS: Clinical signs useful in assessment of level of dehydration were agreed. Admission to a paediatric facility is advised for children who show signs of dehydration. For those with mild to moderate dehydration, estimated deficit is replaced over four hours with oral rehydration solution (glucose based, 200-250 mOsm/l) given "little and often". A nasogastric tube should be used if fluid is refused and normal feeds started following rehydration. Children at high risk of dehydration should be observed to ensure at least maintenance fluid is tolerated. Management of more severe dehydration is detailed. Antidiarrhoeal medication is not indicated. VALIDATION: The guideline has been successfully implemented and evaluated in a paediatric accident and emergency department.

Determining the common medical presenting problems to an accident and emergency department.

All accident and emergency (A&E) attendances over a one year period were prospectively studied in order to determine common medical presenting problems. Data were collected on children (0-15 years) attending a paediatric A&E department in Nottingham between February 1997 and February 1998. A total of 38 982 children were seen. The diagnoses of 26 756 (69%) were classified as trauma or surgical, and 10 369 (27%) as medical; 1857 (4%) could not be classified. The commonest presenting problems reported for "medical" children were breathing difficulty (31%), febrile illness (20%), diarrhoea with or without vomiting (16%), abdominal pain (6%), seizure (5%), and rash (5%). The most senior doctor seeing these patients in A&E was a senior house officer (intern or junior resident) in 78% of cases, paediatric registrar (senior resident) in 19%, consultant (attending physician) in 1.4%, and "other" in 2.6%. Guidelines developed for A&E should target the commonest presenting problem categories, six of which account for 83% of all medical attendances, and be directed towards senior house officers.

Accounting for overlap? An application of Mezzich's kappa statistic to test interrater reliability of interview data on parental accident and emergency attendance.

STUDY RATIONALE: The number of interview studies with service users is rising because of growth in health services research. The level of agreement between multiple interview data coders requires statistical calculation to support results. Basic kappa statistics are often used but this depends on having mutually exclusive data. Researchers should be aware that this is not valid when an interview word or paragraph can be coded into more than one category. The 'proportional overlap' kappa extension by Mezzich et al. (1981, Journal of Psychiatric Research 16, 29-39) has been investigated as an original solution. OBJECTIVES: To assess the level of agreement beyond chance between several raters of interview data by applying the 'proportional overlap' kappa statistic by Mezzich et al. to verbal interview data. The clinical area investigated was child attendance at an Accident and Emergency Department, where parental attendance experiences have been under-explored. METHODS: Two researchers using a coding schedule coded a random sample of interview transcripts. These data were applied to Mezzich's procedure; coder 1 notes that a paragraph refers to category A and B but coder 2 notes A, B and C. The total agreement overlap in this case was 0.66 because two actual agreements out of three possible agreements were made. This was repeated for each paragraph and divided by the number of coding pairs. All agreement values were summed then subsequently divided by the total number of paragraphs to get Po (total number of observed agreements) and by the total number of coding pairs to get Pe (total number of agreements by chance alone). Po and Pe were used in the basic kappa formula to assess interview coding reliability. RESULTS: The overall mean Po was 0.61, the mean Pe was 0.32, with a kappa score of 0.43; a moderate level of agreement which was statistically significant (t=4.8, P < 0.001, d.f.=23). CONCLUSION: Mezzich's procedure may be applied to interview data to calculate agreement levels between several coders.

Clinical training experience in district general hospitals.

AIMS: To estimate the nature and quantity of clinical experience available for trainees in paediatrics or general practice in acute general hospitals of differing sizes in the UK. To discuss implications for training and service configuration taking account of current Royal College recommendations (a minimum of 1,800 acute contacts each year and ideally covering a population of 450,000 to 500,000 people). METHODS: Observed frequencies of diagnoses in Pinderfields Hospital, Wakefield were compared with those in five other hospitals in Yorkshire and four in the South of England, and with expected frequencies from a review of selected marker conditions using national routine and epidemiological data. Based on the Pinderfields data, we modelled expected frequencies of a wider range of diagnoses for different sized hospitals. RESULTS: Small units (1,800 or less acute referrals a year) provide adequate exposure to common conditions such as gastroenteritis (157 per annum) and asthma (171 per annum) but encounter serious or unusual disease rarely. When modelled for units serving larger populations, numbers of such disorders remain small. For example, about 0.5% of admissions require intensive care to the level of ventilatory support. Medium size units offer a wide range of experience but differ little from those serving the population of 500,000 proposed as being optimal for training. This standard is not justified by the evidence in this review. Closing or amalgamating units on the scale necessary to achieve this ideal would be impractical as only five hospitals in England have a paediatric workload equivalent to this population; it would also raise issues of access and equity.

Generalised uridine diphosphate galactose-4-epimerase deficiency.

The generalised form of epimerase deficiency galactosaemia has been described in only two children from unrelated families. Their progress is reported and three other affected children from these families are described. The initial presentation was similar to classic galactosaemia. Despite treatment all have shown poor growth and moderate learning difficulties. Three have sensorineural deafness and four have pronounced dysmorphic features. The two older female patients have normal pubertal development.

Parental and professional perception of need for emergency admission to hospital: prospective questionnaire based study.

AIM: To compare views of parents, consultants, and general practitioners on severity of acute illness and need for admission, and to explore views on alternative services. METHOD: Prospective questionnaire based study of 887 consecutive emergency paediatric admissions over two separate three week periods in summer and winter of five Yorkshire hospitals, combined with a further questionnaire on a subsample. OUTCOME MEASURES: Parental scores of need for admission and parent and consultant illness severity scores out of 10. Consultant judgment of need for admission. Alternatives to admission considered by consultants and, for a subsample, by parents and family GP. RESULTS: Ninety nine per cent of parents thought admission was needed. Parents scored need for admission more highly than severity of illness with no association observed between severity and presenting problem or diagnosis. High parental need score was associated with a fit, past illness, and length of stay. Consultant illness severity scores were skewed to the lower range. Consultants considered admission necessary in 71%, especially for children aged over 1 year, presentation with breathing difficulty or fit, and after a longer stay. More admissions in the evening were considered unnecessary as were admissions after longer preadmission illness, gastroenteritis, or upper respiratory tract infection. Of a subsample of parents, 81% preferred admission during the acute stage of illness even if home nursing had been available. Similar responses were obtained from GPs. Alternative services could have avoided admission for 19% of children, saving 15.6% of bed days used. CONCLUSIONS: Medical professionals and parents differ in their views about admission for acute illnesses. More information is needed on children not admitted. Alternative services should take account of patterns of illness and should be acceptable to parents and professionals; cost savings may be marginal.

Medical and social factors associated with the admission and discharge of acutely ill children.

AIM: To examine medical and sociodemographic factors involved in acute paediatric admission. To compare outcome of admission with factors present at time of admission. METHODS: Prospective questionnaire based study of 887 consecutive emergency general paediatric admissions to five Yorkshire hospitals during two separate three week periods in summer and winter. MAIN OUTCOME MEASURES: Discharge diagnosis, length of stay. RESULTS: Most admissions (53%) occurred "out of hours" with a peak during the evening. Two thirds (64%) of patients were under 3 years of age and clinical problems varied with age. Self referral via an accident and emergency department occurred in one third and was more likely after a fit in older children and in more socioeconomically deprived children. The most frequent presenting problems were breathing difficulty (24%), fit (16%), and feverish illness (15%). One quarter (24%) were discharged within 24 hours and 61% spent, at most, one night in hospital. Length of stay was shorter for night admissions and longer for children with a discharge diagnosis of asthma. Although most children had mild, self limiting illnesses, serious illness was subsequently found in 13% and could not be predicted from the presenting problems. CONCLUSIONS: Current demand on emergency paediatric admission is mainly from young children with mild self limiting illnesses who spend one night or less in hospital. Changes in delivery of care to acutely ill children must take account of the pattern and nature of presenting problems and be rigorously audited to ensure that improvements in the health of children continue.

Validation of the paediatric appropriateness evaluation protocol in British practice.

The reliability and validity of the North American paediatric appropriateness evaluation protocol (PAEP) for use in paediatric practice in Britain was tested. The protocol was applied to 418 case records of consecutive emergency admissions to three Yorkshire district general hospitals. The PAEP ratings were then compared with a clinical consensus opinion obtained from two expert panels. Altogether 32% of the admissions were rated inappropriate by the PAEP and 36% by the panels. Validity of the PAEP, as measured by agreement beyond chance with the expert panel rating, was only moderate with a kappa of 0.29 (95% confidence interval 0.11 to 0.47). The PAEP has limited validity for evaluating British paediatric practice. Utilisation review instruments developed in differing clinical cultures should be used with caution until shown to be valid for the practice setting under review.

The management of pyloric stenosis in a district hospital.

Over a 10-year period, 80 infants were admitted with a diagnosis of pyloric stenosis. Seventy-nine underwent surgical pyloromyotomy (63 male, 16 female; mean age 5.6 weeks). Fifty-nine infants (75%) were operated upon by one of four consultant surgeons and 20 (25%) operations were undertaken by a registrar. Seventy operations (89%) were performed during normal working hours and thirty of these (43%) were placed first on the operating list. The mean length of stay was 6.9 days. Three infants required re-operation: there were two instances of wound dehiscence and one episode of bleeding from the edge of the pyloromyotomy. There were no deaths. The morbidity and mortality in this series was comparable with published results from specialist units.

Appropriateness of paediatric admission.

A study of the 'appropriateness' of 267 consecutive emergency admissions to a district paediatric department showed that admission was at a peak in the evening and night time. Breathing difficulty, head injury, and fever were the commonest presenting problems. Sixty three per cent of admissions occurred between 6 pm and 8 am and these were more likely to be after self referral to the accident and emergency department and were evenly distributed through the social classes. Overall 80.5% of admissions were considered to be necessary on medical grounds by the consultants at the time of discharge. Parental assessment of severity of illness and need for admission correlated well with that of the doctors. Fifty two per cent of all admissions took place though the accident and emergency department, and although a higher number of these were from disadvantaged families these were equally appropriate on medical grounds to those sent for admission by the general practitioner. Altogether 26.5% of admissions were for less than 24 hours and half of these were judged to be unnecessary. Implications for the organisation of inpatient care are discussed.

Paediatric inpatient utilisation in a district general hospital.

Paediatric inpatient utilisation in a district general hospital was studied for 20 general practices covering a population of 26,433 children. The factors influencing the rate and route of admission (general practitioner (GP) or accident and emergency department) were analysed for 894 emergency non-traumatic admissions over a 12 month period. The overall rate of acute, nontraumatic admission was 33.8/1000; 35% of these admissions were via the accident and emergency department. Asthma was the most common reason for admission (16.1%); 56.9% of the admissions resulted from respiratory tract illness and 44% were for an infective illness. There was a significant variation in the route and rate of admission across practices. Admission rates ranged from 10 to 70/1000 children under 15 and the proportion via the accident and emergency department from 19% to 85%. The proportion of admissions via the accident and emergency department for each practice was highly negatively correlated with the number of GPs in the practice, the number of children under 15 registered, and positively correlated with the unemployment rate attributed to the list. Using multiple logistic regression analysis, the risk of being admitted via the accident and emergency department relative to GP admission was shown to be higher for older children (odds ratio for each year of age 1.05) and less for children registered with large practices with more GPs (odds ratio for each extra GP 0.36) or practices with more children under 15 (odds ratio per extra child 0.9991). Access to hospital as measured by isochrone bars and social characteristics of the ward of residence of each child admitted were not associated with the route of admission. The admission rate for each practice was positively, but not statistically significantly, associated with the unemployment rate attributed to the list, the unemployment rate of the ward where the practice was located, and the percentage of admissions via accident and emergency, and negatively associated with the percentage of the list under 15 years.
