Effect of NHS walk-in centre on local primary healthcare services: before and after observational study

ObjectiveTo assess the effect of an NHS walk-in centre on local primary and emergency healthcare services.DesignBefore and after observational study.SettingLoughborough, which had an NHS walk-in centre, and Market Harborough, the control town.Participants12 general practices.ResultsThe change between the before and after study periods was not significantly different in the two towns for daily rate of emergency general practice consultations (mean difference −0.02/1000 population, 95% confidence interval −0.75 to 0.71), the time to the sixth bookable routine appointment (−0.24 half-days, −1.85 to 1.37), and daily rate of attendances at out of hours services (0.07/1000 population, −0.06 to 0.19). However, attendance at the local minor injuries unit was significantly higher in Loughborough than Market Harborough (rate ratio 1.22, 1.12 to 1.33). Non-ambulance attendances at accident and emergency departments fell less in Loughborough than Market Harborough (rate ratio 1.17, 1.03 to 1.33).ConclusionsThe NHS walk-in centre did not greatly affect the workload of local general practitioners. However, the workload of the local minor injuries unit increased significantly, probably because it was in the same building as the walk-in centre.

What is already known on this topic

Walk-in centres are well established in North America but differ from NHS centres as they are run by doctors not nurses

What this study adds

Introduction of an NHS walk-in centre did not affect the workload of local general practitionersAttendance increased at the minor injuries unit, which was in the same buildingNon-ambulance attendances at accident and emergency departments decreased but not by as much as in the control area     

Casual Attendances at an Accident Department and a Health Centre

In six months patients from a defined population of 11,417 provided 826 casual attendances for minor conditions at a hospital accident department and 1,430 similar attendances at a health centre treatment room. Attendances at the accident department reached a peak during the early evening, and included relatively more males, more adults, more patients with injuries than with symptoms, and more residents from the area immediately adjoining the hospital.Care of most of the casual attenders with minor conditions at the health centre treatment room would require additional nursing staff and some reorganization of primary care to enable a doctor to be available at most times. Attendances at night and at week-ends were insufficient to justify a 24-hour service at the health centre.     

Microcomputer system in an accident unit.

A microcomputer-based records system has been developed for use in the accident unit of a district general hospital. Patient details are entered directly at the reception desk and the computer generates a casualty card that is updated after the patient has been seen by the doctor, who determines the diagnosis to be recorded and specifies the injury coding. Information is stored on floppy discs, each holding the details of 3400 patients. The computer is used to produce a daily log-book of attendances, including revisits. The stored data may be examined and analysed for both administrative and medical purposes. The work load can be rapidly analysed according to various options that include the nature, type, and site of injuries. The system was introduced in December 1980. Location within the unit allows control over its operation, and many of the limitations of a manual system have been overcome.     

Morbidity and mortality of car occupants: comparative survey over 24 months.

The severity of injuries sustained by 2577 car occupants in road traffic accidents in the catchment area of one district accident service during February 1982 to January 1984 inclusive was assessed using the injury severity score system. In the first 12 months the mean injury severity score for front seat occupants injured in a road traffic accident was 4.94 and in the second 12 month period, after the implementation of the seat belt law, the mean injury severity score of all injured front seat occupants was 2.80. These figures indicated a reduction in injury severity of front seat occupants of 53.4% on the previous 12 month figures. The severity of injury sustained by unbelted front seat occupants and back seat passengers showed no significant change over the two years. The number of front seat occupants killed or sustaining serious injuries (injury severity score greater than 12) showed a reduction of 54% in the 12 months beginning February 1983. Front seat occupants requiring admission for injuries sustained showed a decline of 42% in the 12 months after the introduction of the seat belt law, and deaths among front seat occupants fell by 27% compared with the previous 12 months. After the implementation of seat belt legislation those front seat occupants killed or sustaining serious injuries included a significantly higher proportion of victims who were not wearing their seat belts or showed positive evidence of alcohol intake at the time of the accident. This series suggests that the incidence of serious injury or deaths among front seat occupants of cars has decreased substantially since the seat belt law became effective on 31 January 1983.     

Attendance of general practitioners at child protection case conferences.

OBJECTIVE--To investigate general practitioners'' attendance at and views on child protection conferences and their confidence in dealing with sexual abuse in children. DESIGN--Anonymous postal questionnaire sent to all general practitioners in Tower Hamlets and review of consecutive case conferences held by social services for three months in 1989. SETTING--Tower Hamlets health district. SUBJECTS--91 general practitioners, 56 of whom (62%) responded. MAIN OUTCOME MEASURES--Number of conferences attended, reasons for non-attendance, and reported confidence in dealing with sexual abuse. RESULTS--General practitioners estimated that 202 child protection conferences had been held in 1989 on their patients and that they had attended 85 of these. Information from social services for three months suggested that general practitioners had attended only nine of the 114 conferences reviewed. Timing of the conference was the most important reason for non-attendance. All respondents wanted access to the minutes of these conferences irrespective of their own attendance. Most general practitioners were very or moderately confident of their ability to detect child sexual abuse and non-accidental injury and to communicate with the family. CONCLUSION--More effort should be made to ensure that general practitioners are notified of case conferences and that the timing and location of conferences is compatible with their other commitments.     

Contribution of a general practitioner hospital: a further study.

OBJECTIVE--To audit the workload of a general practitioner hospital and to compare the results with an earlier study. DESIGN--Prospective recording of discharges from the general practitioner hospital plus outpatient and casualty attendances and of all outpatient referrals and discharges from other hospitals of patients from Brecon Medical Group Practice during one year (1 June 1986-31 May 1987). SETTING--A large rural general group practice which staffs a general practitioner hospital in Brecon, mid-Wales. PATIENTS--20,000 Patients living in the Brecon area. RESULTS--1540 Patients were discharged from the general practitioner hospital during the study period. The hospital accounted for 78% (1242 out of 1594) of all hospital admissions of patients of the practice. There were 5835 new attendances at the casualty department and 1896 new outpatient attendances at consultant clinics at the hospital. Of all new outpatient attendances by patients of the practice, 71% (1358 out of 1896) were at clinics held at the general practitioner hospital. Since the previous study in 1971 discharges from the hospital have increased 37% (from 1125 to 1540) and new attendances at consultant clinics 30% (from 1450 to 1896). The average cost per inpatient day is lower at this hospital than at the local district general hospital (pounds 71.07 v pounds 88.06 respectively). CONCLUSIONS--The general practitioner hospital deals with a considerably larger proportion of admissions and outpatient attendances of patients in the practice than in 1971 and eases the burden on the local district general hospital at a reasonable cost. IMPLICATIONS--General practitioner hospitals should have a future role in the NHS.     

Effectiveness of a regional trauma system in reducing mortality from major trauma: before and after study.

OBJECTIVE: To assess the effect of the development of an experimental trauma centre and regional trauma system on the survival of patients with major trauma. DESIGN: Controlled before and after study examining outcomes between 1990 and 1993, spanning the introduction of the system in 1991-2. SETTING: Trauma centre in North Staffordshire Royal Infirmary and five associated district general hospitals in the North West Midlands regional trauma system, and two control regions in Lancashire and Humberside. SUBJECTS: All trauma patients taken by the ambulance services serving the regions or arriving other than by ambulance with injury severity scores > 15, whether or not they had vital signs on arrival at hospital. MAIN OUTCOME MEASURES: Survival rates standardised for age, severity of injury, and revised trauma score. RESULTS: In 1990, 33% of major trauma patients in the experimental region were taken to the trauma centre, and by 1993 this had risen to only 39%. Crude death rates changed by the same amount in the control regions (46.5% in 1990-1 to 44.4% in 1992-3) as in the experimental region (44.8% to 41.3%). After standardisation, the estimated change in the probability of dying in the experimental region compared with the control regions was -0.8% per year (95% confidence interval -3.6% to 2.2%); for out of hours care, the change was 1.6% per year (-2.3% to 5.6%), and, for multiply injured patients, the change was -1.6% (-6.1% to 2.6%). CONCLUSION: Any reductions in mortality from regionalising major trauma care in shire areas of England would probably be modest compared with reports from the United States.     

Self referral to an accident and emergency department for another opinion.

OBJECTIVE--To determine whether patients referring themselves to an accident and emergency department for another opinion after consulting their general practitioner present with serious illness, show any risk factors for being admitted, or are more likely to be patients of particular practitioners. DESIGN--Six month prospective survey. SETTING--District general hospital''s accident and emergency department, receiving 42,000 new patients a year. PATIENTS--180 Patients identified as attending for another opinion having already consulted a general practitioner. INTERVENTIONS--Classified as admission, referral to specialist clinic, follow up in accident and emergency department, or referral back to general practitioner. END POINT--Admission, with an analysis of admitted patients. MEASUREMENTS AND MAIN RESULTS--General outcome, diagnostic category, age, time of attendance, time since seen by general practitioner, and name of general practitioner were recorded. Forty seven patients were admitted, 99 were discharged back to the general practitioner (62 without a letter), and two died. Patients were most likely to be admitted if they attended within 24 hours after seeing a general practitioner, were aged under 5, or presented with respiratory or gastrointestinal complaints. Some general practitioners were overrepresented. CONCLUSIONS--Important disorders present in this way, and therefore these patients should be seen by a doctor. Information about these attendances could be useful to general practitioners in reviewing their performance.     

The hit and miss of ISS and TRISS. Yorkshire Trauma Audit Group.

OBJECTIVE--To measure interobserver variation in recording injury from case notes and its effect on calculating injury severity scores (ISS) from identical data and predicting probabilities of survival by using the combined trauma and injury severity score (TRISS). DESIGN--Observer variation study using injury severity scoring and subsequent calculation of probability of survival based on combined trauma and injury severity scores. SUBJECTS--16 patients with a range of injury severity scores, and 15 observers. RESULTS--There was a wide variation in recorded injury severity scores, the probability of two observers agreeing on the score being 0.28 (28%). The probability of any two observers agreeing over which severity band the patient should be in was 0.5 (50%). Observer variation was independent of the training and type of observer. Survival probability (calculated by combined trauma and injury severity scoring methodology from individual observers'' scores) varied by over 0.2 in six of the 16 patients and by over 0.5 in three. CONCLUSIONS--There is wide observer variation in injury severity scoring, which highlights a potential fallibility in its use for trauma audit. The use of combined trauma and injury severity scoring for individual prediction of survival is potentially inaccurate except at the extremes of probabilities. The use of the 0.5 survival line on a combined trauma and injury severity score "pre-chart" is statistically and clinically inappropriate.     

Bicycle-related injuries: a survey in a pediatric emergency department.

The number of bicycle-related injuries has risen significantly with the increased popularity of bicycle riding in Canada. The risk of injury is highest among children. To assess the magnitude of the problem and to identify the contributing factors we used a questionnaire, injury reports and patient charts to survey bicycle-related injuries among children brought to the emergency department of the Children''s Hospital of Eastern Ontario, Ottawa, between May 1 and Sept. 30, 1988. The questionnaire was completed for 517 (91%) of the 568 children; 70% were boys, and the mean age was 9.4 years. Only 2% of the patients had been wearing a helmet at the time of injury, although 13% claimed to own one for cycling. Over 60% of the accidents were attributable to carelessness or poor bicycle control; mechanical failure and environmental hazards were minor factors. Over 80% of the injuries occurred within a kilometre of the child''s home. Of the 97 children admitted to hospital 49% had head and skull injuries and 40% had limb fractures. Bicycle-related injuries represented 14.8% of all nonwinter (Apr. 1 to Oct. 31) trauma admissions among children 5 years or older. Our results further document bicycle-related injuries as an important childhood problem and underscore the need for improved safety measures.     

Reducing accident death rates in children and young adults: the contribution of hospital care. Steering Committee of the Major Trauma Outcome Study Group.

OBJECTIVE: To assess the contribution of trauma care to the recent decline in accident death rates among children and young people. DESIGN: Logistic regression modelling of temporal trends in the probability of death in patients admitted to hospital for the treatment of severe injury. SETTING: Hospitals participating the United Kingdom major trauma outcome study. SUBJECTS: 3230 patients with an injury severity score of 16 or more, who were admitted for more than three days, transferred or admitted to intensive care, or died from their injuries. MAIN OUTCOME MEASURES: Death or survival in hospital within three months of injury. RESULTS: Over the seven year period 1989-95 there was a substantial decline in the probability of death among children and young adults admitted to hospital after severe injury. The overall estimate of the reduction in the odds of death was 16% per year (odds ratio for the yearly trend 0.84; 95% confidence interval 0.79 to 0.89). This decline did not differ significantly between age groups. (0-4 years 0.79; 5-14 years 0.87; 15-24 years 0.83). CONCLUSIONS: Reductions in hospital case fatality have made an important contribution to reaching the Health of the Nation targets. The contribution of hospital care in the reduction of accident mortality should be taken into account in decisions about the allocation of resources to preventive and curative services.     

Improving the care of patients with major trauma in the accident and emergency department.

OBJECTIVE--To determine whether improvement in the care of victims of major trauma could be made by using the revised trauma score as a triage tool to help junior accident and emergency doctors rapidly identify seriously injured patients and thereby call a senior accident and emergency specialist to supervise their resuscitation. DESIGN--Comparison of results of audit of management of all seriously injured patients before and after these measures were introduced. SETTING--Accident and emergency department in an urban hospital. PATIENTS--All seriously injured patients (injury severity score greater than 15) admitted to the department six months before and one year after introduction of the measures. RESULTS--Management errors were reduced from 58% (21/36) to 30% (16/54) (p less than 0.01). Correct treatment rather than improvement in diagnosis or investigation accounted for almost all the improvement. CONCLUSIONS--The management of seriously injured patients in the accident and emergency department can be improved by introducing two simple measures: using the revised trauma score as a triage tool to help junior doctors in the accident and emergency department rapidly identify seriously injured patients, and calling a senior accident and emergency specialist to supervise the resuscitation of all seriously injured patients. IMPLICATIONS--Care of patients in accident and emergency departments can be improved considerably at no additional expense by introducing two simple measures.     

ISS与APACHEⅡ评分对急诊多发伤患者伤情评估的价值分析

目的:探讨损伤严重程度计分法(Injuryseverityscore,ISS)和慢性健康评分(Acute physiology and chronic health evaluation scoreⅡ,APACHEⅡ)评分对急诊多发伤患者伤情评估的应用价值。方法:将我院自2016年6月至2019年6月急诊收治的多发伤患者85例作为研究对象,分别使用ISS和APACHEⅡ评分,追踪患者住院期间的伤情严重程度和预后情况。结果:急诊多发伤患者入院时ISS评分和APACHEⅡ评分越高,患者ICU收住率和死亡率越高,患者预后越差(P0.05);死亡的急诊多发伤患者ISS评分和APACHE-Ⅱ评分均明显高于存活组(P0.05)。ISS评分预测急诊多发伤患者死亡的灵敏度为87.06%,特异性为85.88%,APACHE-Ⅱ评分预测急诊多发伤患者死亡的灵敏度和特异性分别为88.24%和87.06%,差异无统计学意义(P0.05),两者联合预测急诊多发伤患者死亡的灵敏度为95.29%,特异性为94.12%,均优于单独预测(P0.05)。结论:ISS评分和APACHE-Ⅱ评分能够较为准确的评估急诊多发伤患者的病情严重程度,对患者预后具有较好的预测价值,两者结合使用的应用价值更高。     

Preliminary analysis of the care of injured patients in 33 British hospitals: first report of the United Kingdom major trauma outcome study.

OBJECTIVE--To measure the effectiveness of management of major trauma in the United Kingdom. DESIGN--Review of the care of all seriously injured patients seen over two years. SETTING--33 hospitals which receive patients who have sustained major trauma. SUBJECTS--14,648 injured patients admitted for more than three days, transferred or admitted into an intensive care bed, or dying from their injuries. MAIN OUTCOME MEASURE--Death or survival in hospital within three months of the injury. RESULTS--21% of seriously injured patients (1299) took longer than one hour to reach hospital. Time before arrival at hospital was not related to severity of injury. A senior house officer was in charge of initial hospital resuscitation in 57% (826/1445) of patients with an injury severity score > or = 16. More senior staff were commonly responsible for definitive operations, but only 46% (165/355) of patients judged to require early operation arrived in theatre within two hours. Mortality for 6111 patients sustaining blunt trauma and treated in the 14 busiest hospitals was significantly higher (actual 408, predicted 295.6, p < 0.001) than in a comparable North American dataset. Large differences in the 14 hospitals assessed could not be explained by variations in case load or facilities. In contrast, the outcome of the 4.1% (597) of patients with penetrating injuries was better than that of a comparable group in the United States. Analysis of the 415 penetrating injuries with complete data showed that 15 patients died (19.3 predicted; p = 0.04). CONCLUSIONS--The initial management of major trauma in the United Kingdom remains unsatisfactory. There are delays in providing experienced staff and timely operations. Mortality varies inexplicably between hospitals and, for blunt trauma, is generally higher than in the United States.     

Causes of fatal childhood accidents involving head injury in northern region, 1979-86.

OBJECTIVE--To examine the causes and circumstances surrounding fatal accidents involving head injuries in children in the Northern region. DESIGN--Retrospective review of the hospital case notes, necropsy reports, and records of the coroners'' inquests. SETTING--Northern Regional Health Authority. PATIENTS--All 255 children aged less than 16 years who died with a head injury during 1979-86. MAIN OUTCOME MEASURES--Cause of injury and circumstances of accident according to reports of inquests; injury severity score; number of fatal accidents and mortality per 100,000 children in 10 groups of local authority wards ranked according to their score on the overall deprivation index; and distance of site of accident from child''s home. RESULTS--Of the 255 children who died after a head injury, 136 (53%) children were playing at the time of the accident. 195 (76%) children sustained the head injury in road traffic accidents, 135 as pedestrians, 35 as cyclists, and 25 as passengers in a vehicle. In 120 accidents in child pedestrians the primary cause of accident was the unsafe behaviour of the child. 172 (67%) accidents occurred within one to two km of the child''s home and 153 (63%) between 3 pm and 9 pm. The mortality was significantly related to social deprivation; excluding eight children injured while on holiday in the region, 15-fold decrease in mortality was recorded between the local authority wards that ranked highest on the overall deprivation index and those that ranked lowest (14.0/100,000 children, group 10 v 0.9/100,000, group 1 respectively, p less than 0.00001). CONCLUSIONS--The finding that most accidents occurred in children living in deprived areas who were playing unsupervised near their home suggests that childhood mortality might be appreciably reduced if children at play were protected from traffic, particularly in socially deprived areas.     

Serious childhood injuries caused by air guns.

OBJECTIVE: To determine the severity of nonfatal injuries to children caused by air guns and pellet guns. DESIGN: Case series (hospital chart review). SETTING: Inpatient wards of the Children''s Hospital of Eastern Ontario. PATIENTS: All children under 18 years of age admitted to the hospital from Jan. 1, 1979, to Dec. 31, 1989, under ICD code E917, E922, E955, E965, E970 or E985 who had suffered air gun injuries. MAIN OUTCOME MEASURES: Personal data, circumstances of event and clinical data. RESULTS: The 43 children (37 boys) had a median age of 12 years. The circumstances of the accident were known in 20 cases: 17 children were playing and 3 were cleaning the gun when it went off. Four children thought the gun was unloaded. In five cases the bullet ricocheted into the eye. Nine injuries were self-inflicted. Injury was to the extremities in 21 (49%), the eyes in 15 (35%) and the head and neck in 7 (16%). The median length of hospital stay was 4 days. Six children had long-term disabilities, all the result of eye injuries; two had cataract surgery, and four required enucleation of the eye. CONCLUSIONS: Air guns can cause serious injury to children. Their sale needs to be banned or at least carefully regulated.     

Comprehensive care of patients with head injuries.

The comprehensive head injury service run by the neurosurgeons at the Hull Royal Infirmary for the surrounding population of one million was analysed. The analysis showed that all patients with either a fractured skull or a lowered level of consciousness should be admitted to a district general hospital because the associated risk of their having a major head injury is over 20%. Those patients with both a fractured skull and a lowered level of consciousness have a 60% likelihood of a major head injury and should be transferred immediately to the neurosurgical unit. Patients with compound or complicated fractures of the skull and those without fractured skulls but with neurological impairment persisting for four hours or more, should also be transferred to the neurosurgical unit. If these guidelines are followed about 200 patients/million population will be referred to the neurosurgical centre. Patients with a minor head injury and none of the clinical risk factors may safely be sent home. This should reduce the rate of admissions to hospital for head injuries by 60%.     

Caseload or workload? Scoring complexity of operative procedures as a means of analysing workload.

OBJECTIVE--To present a more realistic assessment of surgical workload than that provided by a case count. DESIGN--Prospective study of all the operative procedures performed in one year, classified according to the British United Provident Association''s schedule of procedures and scored by the "intermediate equivalent" value (taking the recommended fee value of an intermediate operation as 1.0) compared with the number of operations performed. SETTING--General surgical unit of Taunton and Somerset Hospital, comparing four consultant surgeons and their teams. PATIENTS--Inpatients and day patients admitted under the care of general surgeons during 1989. MAIN OUTCOME MEASURE--Difference between the apparent workload represented by simple case counting (caseload) and the actual workload represented by calculation of the total "intermediate equivalent" value. RESULTS--The workload assessed in terms of intermediate equivalent values was greater than that suggested by case counting for complex operations (12% v 4%), operations at the district hospital (82% v 74%), and operations performed by consultants (53% v 35%) and was lower for minor operations (20% v 42%), operations at the community hospitals (18% v 26%), and operations performed by surgeons in training grades and clinical assistants (47% v 66%). CONCLUSIONS--The use of the intermediate equivalent values as an indicator of complexity allows a more realistic assessment of the operative workload than a simple case count of the number of different operations and is recommended for comparing workload in different hospitals and departments.
