Randomised controlled trial comparing hospital at home care with inpatient hospital care. II: cost minimisation analysis

OBJECTIVES

To examine the cost of providing hospital at home in place of some forms of inpatient hospital care.

DESIGN

Cost minimisation study within a randomised controlled trial.

SETTING

District general hospital and catchment area of neighbouring community trust.

SUBJECTS

Patients recovering from hip replacement (n=86), knee replacement (n=86), and hysterectomy (n=238); elderly medical patients (n=96); and patients with chronic obstructive airways disease (n=32).

INTERVENTIONS

Hospital at home or inpatient hospital care.

MAIN OUTCOME MEASURES

Cost of hospital at home scheme to health service, to general practitioners, and to patients and their families compared with hospital care.

RESULTS

No difference was detected in total healthcare costs between hospital at home and hospital care for patients recovering from a hip or knee replacement, or elderly medical patients. Hospital at home significantly increased healthcare costs for patients recovering from a hysterectomy (ratio of geometrical means 1.15, 95% confidence interval 1.04 to 1.29, P=0.009) and for those with chronic obstructive airways disease (Mann-Whitney U test, P=0.01). Hospital at home significantly increased general practitioners' costs for elderly medical patients (Mann-Whitney U test, P<0.01) and for those with chronic obstructive airways disease (P=0.02). Patient and carer expenditure made up a small proportion of total costs.

CONCLUSION

Hospital at home care did not reduce total healthcare costs for the conditions studied in this trial, and costs were significantly increased for patients recovering from a hysterectomy and those with chronic obstructive airways disease. There was some evidence that costs were shifted to primary care for elderly medical patients and those with chronic obstructive airways disease.

Pay in the British NHS: a local solution for a national service?

An important component of the reforms of the British National Health Service (NHS) has been devolution of a previously highly centralised pay bargaining system to the local provider level. As the wage bill is by far the single largest item of health care expenditure, the implications of this change may be far-reaching. This article surveys the available theory and evidence from an economic perspective. It reviews the development of pay determination mechanisms in the NHS and the extent to which local pay has been adopted since the reforms were introduced. It then considers the theory of local pay and general evidence on local pay variations in the UK, before turning to the available evidence on local labour markets in the health care sectors of the UK and USA. It concludes with a discussion of the policy and research implications of current developments on local pay bargaining in the NHS. In particular, it suggests that judgements over the success or failure of local pay bargaining will concern: first, whether the weakened monopsony position of the NHS at national level results in higher pay for the more powerful employee groups; second, whether fragmentation of bargaining weakens the negotiating and lobbying power of national trade unions and professional organisations; third, whether competition between providers leads to higher or lower costs; and fourth, whether any efficiency gains from local bargaining outweight the higher transaction costs involved.

Persistence of parvovirus B19 DNA in testis of patients with testicular germ cell tumours

Germ cell tumours (GCT) of the testis are the most common malignant tumours occurring in young adults. In view of the young age of patients, the increasing incidence of GCT and the overexpression of wild-type p53 observed in a majority of tumours, the possibility of the involvement of a virus in the development of this cancer was considered. Testicular GCT were analysed for the presence of cytomegalovirus and Epstein-Barr virus (EBV), which are known to cause overexpression of wild-type p53 protein, and parvovirus B19. The testicular tissue of 39 patients with testicular GCT and 12 patients with healthy testicular tissues was tested for presence of viral DNA by PCR. Neither cytomegalovirus nor EBV DNAs were detected in the 39 tumours analysed, but parvovirus B19 DNA sequences were demonstrated in the testicular tissue of 85% (33/39 cases) of patients with GCT. The sera of 16 of the 39 patients with GCT were tested for the presence of parvovirus B19 IgM and IgG. B19-specific IgG was detected in the sera of 11 patients (69%). Only one case was positive for parvovirus B19 IgM, which was also shown to have B19 genome sequences in the serum by PCR, indicating that in a majority of cases an acute B19 infection can be excluded as being the source of the B19 DNA sequences in the testis. B19 DNA could not be detected in normal testicular tissue and thus parvovirus B19 could play a role, direct or indirect, in the development of testicular GCT or have tropism for the tumour cells.

The use of out of hours health services: a cross sectional survey

OBJECTIVES

To determine the use and costs of the principal out of hours health services in Buckinghamshire.

DESIGN

Prospective cross sectional survey and cost description of patient contacts with out of hours services.

SETTING

Buckinghamshire during March and April 1995.

SUBJECTS

General practices, accident and emergency departments, ambulance services, and community nursing services.

MAIN OUTCOME MEASURE

Contacts with patients and cost of out of hours services.

RESULTS

438 patient contacts/1000 population/year were recorded at an annual incremental cost of between 4.6 m Pounds and 7.2 m Pounds (depending on the costing of general practitioner services), for a population of 660,000. Of these contacts, 21,649 (45%) were with general practitioners. Night time contacts with all services diminished sharply after 10 pm. General practitioners considered that 40% of contacts were unnecessary or could have waited until morning. Over 70% of contacts were for upper respiratory tract infections, earache, gastroenteritis, and other minor ailments. Nursing care was predominantly for elderly people, and 33% of nursing contacts were to supervise medication. Accident and emergency care was predominantely for young adults, especially men, and 41% of attendances were for medical conditions.

CONCLUSIONS

New models such as multidisciplinary primary care centres with telephone advice lines and triaging are required to ensure high quality, cost effective care that is responsive to the needs of both consumers and professionals.

Caregivers of children with sexual behavior problems: psychological and familial functioning

OBJECTIVE

This research examined demographic and functional characteristics of parents of children with sexual behavior problems.

METHOD

Families of 72 children with sexual behavior problems completed a structured interview and several psychometric devices at intake into a treatment outcome study.

RESULTS

As a group, caregivers manifested signs of a high level of life stress across a wide array of variables, including income, criminal arrest, family violence, sexual abuse, social support, modulation of emotion, and attachment to their child. Foster parents consistently reported significantly lower levels of stress than biological parents.

CONCLUSION

Parents and families of children with sexual behavior problems appear multiply entrapped. They are highly distressed and somewhat isolated. The data convincingly demonstrate that in order to maximize the efficacy of treatment for children with sexual behavior problems, parents must be centrally involved and receive services coordinated with those of their child. Group treatment may be advisable to foster formation of a network of peer support for caregivers of children with sexual behavior problems.

Wine tasting and dental erosion. Case report

A case of widespread dental erosion is reported in an individual who had worked in the wine industry for ten years. This occupation involved daily tasting of at least 20 wines, but often more. The erosion manifested as dental sensitivity with there being cervical erosion, occlusal pitting, and loss of enamel around restorations. The effect of immersing unerupted human teeth in white wine (pH 3.3) was examined with the scanning electron microscope, where marked surface changes had occurred after 24 hours of exposure.

An economic evaluation of vaccination against hepatitis A for frequent travellers

This paper compares the cost of using inactive Hepatitis A vaccine relative to immunoglobulin as a means of protecting frequent travellers against Hepatitis A. The number of trips to 'at risk' areas is modelled as a Poisson process and results are reported in terms of the discounted gross cost per protected trip over a 10-year period. We find that the expected cost of immunization is lower with immunoglobulin for travellers visiting 'at risk' areas less than five times in 10 years, and lower with Hepatitis A vaccine for those visiting 'at risk' areas more than five times in 10 years.

The future of general medicine: lessons from an admissions ward

OBJECTIVE

To define the expertise required of general physicians by surveying the work of an admissions ward.

DESIGN

Observational study during a three-year period.

SETTING

A 30-bed medical admissions ward in a district general hospital.

MAIN MEASUREMENTS

Demography, diagnoses and management of 30,798 patients admitted.

RESULTS

Patients admitted as emergencies through the admissions ward made up the bulk of inpatients in general medical and health care of the elderly wards. The most common age group was 70-79 years, and there was a slight predominance of men. Fifty-eight per cent of patients came to hospital as a result of emergency ambulance calls, without the involvement of a general practitioner. Cardiovascular diagnoses were most common (40% of patients) but virtually all medical conditions were represented. Twenty-nine per cent of patients were discharged within 24 hours and few were readmitted.

CONCLUSIONS

Management of patients according to different age groups, or by specialties, does not seem feasible. Although specialty expertise is needed in a district general hospital, only a physician with an interest and training in general medicine can handle the scale and scope of medical emergencies. The majority of physicians still need to be 'general physicians with a special interest'.

Evaluation of index and profile measures of health status in a randomized controlled trial. Comparison of the Medical Outcomes Study 36-Item Short Form Health Survey, EuroQol, and disease specific measures

OBJECTIVES

The authors compare two generic measures of health status with disease-specific measures in a randomized controlled trial of transurethral resection of the prostate with laser vaporization prostatectomy for benign prostatic hypertrophy.

METHODS

Patients entered into the trial completed the following questionnaires prior to treatment and at follow-up at 3 months and 1 year. The Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) is a generic measure that produces an eight-dimension profile as well as two summary measures of health status (the physical component score and the mental component score). The EuroQol provides two single index measures of health status; one intended to convey the utility (or lack of) that an individual derives from his or her own health state compared with alternative states and a second simple visual analog scale "thermometer" of health status. The American Urological Association symptom score and the Bothersome index are disease-specific indices of health status for use specifically with benign prostatic hypertrophy patients.

RESULTS

The EuroQol indicates no statistically significant improvements with time for either arm of the trial. The SF-36 physical and general health perceptions domains indicates statistically significant improvements for the transurethral resection of the prostate arm alone at 3 months and 1 year, as do the physical summary score at the 3-month follow-up visit. The effect sizes of these improvements, however, are small, using standard criteria. In contrast, statistically significant differences are found with time for both transurethral resection of the prostate and laser prostatectomy on both disease-specific measures, which also indicate statistically significant superior outcome for the transurethral resection of the prostate arm compared with the laser arm.

CONCLUSIONS

The results indicate that the disease-specific measures are more sensitive to change than the generic measures of outcome. Possible explanations for this are discussed.

Impact of the NHS reforms on English hospital productivity: an analysis of the first three years

OBJECTIVES

To evaluate the effect of purchaser mix, market competition, and trust status on hospital productivity within the NHS internal market.

METHODS

Hospital cost and activity data were taken from routinely collected data for acute NHS hospitals in England for 1991-2 to 1993-4. Cross sectional and longitudinal regression methods were used to estimate the effect of trust status, competition, and purchaser mix on average hospital costs per inpatient, after adjusting for outpatient activity levels, casemix, teaching activity, regional salary variation, hospital size, scale of activity, and scope of cases treated.

RESULTS

Real productivity gains were apparent across the study period for NHS hospitals on average. Casemix adjustment drastically improved cross sectional comparisons between hospitals. Gaining trust status and increasing host district purchaser share were associated with productivity increases after adjustment for casemix, regional salary differences, and hospital size and scope. Hospitals that became trusts during the study period were on average less productive at the beginning of the period than those that did not, and there were no significant productivity differences between trust waves at the end of the period in 1993-4. Market concentration was not associated with productivity differences.

CONCLUSION

Further analysis is needed to determine whether overall and trust associated productivity gains are transient effects, one off shifts, or self perpetuating reorientations of organisational behaviour. Hospitals may have chosen to become trusts because they anticipated being able to increase productivity. Increases in the proportions of small purchasers were associated with increasing costs. Importantly, this study could not adjust for changes in the quality of care.

Vagal control of left ventricular contractility is selectively mediated by a cranioventricular intracardiac ganglion in the cat

Activation of the vagus nerve leads to decreases in sinoatrial (SA) rate, atrioventricular (AV) conduction, and myocardial contractility. Previous data are consistent with the hypothesis that vagal control of cardiac rate and AV conduction are mediated by two anatomically separated and physiologically independent parasympathetic intracardiac ganglia located in fat pads on the surface of the right and left atria, respectively. These data suggested that vagal control of ventricular contractility might be mediated through another intracardiac ganglion. We examined the ventricles of cat hearts histologically for the presence of ganglia. Multiple small basophilic ganglia composed of a few neurons, and an occasional larger ganglion were found embedded in the epicardial fat surrounding the cranial margin of the anterior surface of the left ventricle, near the juncture with the right ventricle, which we refer to as the CV ganglion. In anesthetized cats, right cervical vagal stimulation decreased SA rate by 44 +/- 5%, decreased the rate of AV conduction by 68 +/- 14%, and reduced ventricular contractility by 19.5 +/- 5.7%. Vagally induced negative inotropism was almost completely prevented by microinjection of a ganglionic blocking drug into the CV ganglion. However, these injections into the CV ganglion did not significantly effect vagally induced decreases in either SA rate or AV conduction. We conclude: (1) that ganglia are found in a fat pad on the surface of the left ventricle of the cat heart and (2) that the CV ganglion selectively mediates the negative inotropic effect of vagal stimulation on the left ventricle. Greater understanding of the physiological functions of intracardiac neuronal circuits may help in developing new strategies to treat disorders of cardiac contractility such as congestive heart failure.

Costs and effectiveness of a nurse specialist anticoagulant service

AIMS

To determine the costs and effectiveness of an anticoagulant nurse specialist service compared with a conventional consultant service based on two hospital sites in northwest Hertfordshire.

METHODS

Sequential design comparing retrospectively the conduct and outcomes of a consultant service with a nurse specialist service over two six month periods. In each of the six month study periods, all new patients consecutively referred for anticoagulation over a three month period (group A) at the start of each study period and a random selection of patients who had already been attending the anticoagulant service for one year or more (group B) were included in the study. Group A patients wre followed for up to three months and group B patients for six months. The main outcome measures were costs of service provision and effectiveness. Costs included those for the use of the anticoagulant service, those related to general practitioner (GP) visits and hospitalisations, and running costs (staff time, laboratory tests, patient transport). Measures of effectiveness were the mean proportion of time patients spend in the therapeutic range, the number of drugs being taken that could interact adversely and/or inhibit haemostatic function, and patient and GP satisfaction with service provision.

RESULTS

In the consultant service, for group A there were more patients aged 66-75 years (p = 0.004) and fewer patients aged more than 76 years (p = 0.001); and for group B, there were fewer patients on anticoagulation for cardiac conditions (p = 0.001), but more on anticoagulation for thromboembolic conditions (p = 0.02) than in the nurse specialist service. The clinic running costs of the nurse specialist service were 4.99 Pounds per attendance, compared with 4.75 Pounds in the consultant service. Including all other costs related to treatment, there was no statistically significant difference in cost per patient. There was no significant difference in the proportion of time patients spent in the therapeutic range between the consultant service and the nurse specialist service. In the nurse specialist service, fewer patients in group A were taking drugs that could interact adversely and/or inhibit haemostatic function (p = 0.01) and more patients were satisfied with service provision (p = 0.04) compared with the consultant service. There was no significant variation in GP satisfaction between the two services.

CONCLUSION

In the provision of outpatient anticoagulation, the nurse specialist service was no more expensive than the consultant service and, using our primary outcome, at least as effective. The nurse specialist service has some clear advantages compared to the consultant service: provision of domicilliary care for housebound patients, fewer new patients taking drugs that could interact adversely and/or inhibit haemostatic function patients, it is preferred by newly referred patients to the consultant service, and it is as acceptable to their GPs.

On-scene times for trauma patients in West Yorkshire

OBJECTIVE

To assess whether length of time on-scene in patients with major injury was associated with severity of injury or with abnormal on-scene physiology.

METHODS

A retrospective analysis of a convenience sample of patients in whom prehospital on-scene times were entered onto the regional major trauma database. On-scene times of patients were analysed to assess whether ultimate injury severity score or on scene physiology measurements affected times. This was undertaken by examining subgroups of patients with similar injury severity or physiological measurements by Wilcoxon-Mann-Whitney testing and comparing 95% confidence intervals of the mean on-scene times.

RESULTS

The mean on-scene time for 111 non-entrapped patients was 26 minutes (95% confidence interval 23.5 to 28.6). Patients with injury severity score of > 15, with a Glasgow coma scale of < 13, and with an abnormal pulse spent significantly less time on-scene than less severely injured or physiologically deranged patients.

CONCLUSIONS

Paramedics have the ability to recognise patients with severe injury and reduce on-scene times. On-scene times were consistently long throughout all subgroups of major trauma patients.

Paramedic use of nalbuphine in major injury

Paramedic training and skills have been introduced in the United Kingdom in an attempt to improve prehospital patient care. There is presently little control and quality assurance in this potentially difficult environment and paramedic protocols have not been validated. We studied the use of nalbuphine by paramedics for patients with major injury in West Yorkshire. A case-control study was carried out using two cohorts of patients from the regional Major Trauma Outcome Study (MTOS) database; one group had received prehospital nalbuphine by paramedics (the intervention) and a matched group who had not (the control). Both groups of patients were reviewed by a panel of three consultants and a paramedic to assess which patients received or could have received nalbuphine appropriately. Only 85 patients from a database of 4170 patients received nalbuphine. Fifty-two (61%) patients were thought by the panel to have been given nalbuphine appropriately. The panel also concluded that 21 (18%) of the 115 patient control group could have been administered nalbuphine but did not receive the drug. This study demonstrates inadequate and sometimes inappropriate use of nalbuphine in prehospital trauma care. Quality assurance and audit systems should be implemented to identify and correct these deficiencies.

Palliative care for patients with advanced cancer

The increasing life expectancy in Saudi Arabia will be accompanied by an alteration of the patterns of disease similar to that in Western countries. One of these will be cancer, the second leading cause of death in the west at present, where 1:3 people develop cancer during their lifetime and 1:4 die of it. Cancer deaths are rarely easy. The distress particularly the pain it can cause is legendary. Palliative care is the care and study of patients with active progressive far advanced disease, where cure is impossible, the prognosis predictably short, and the focus of care is the patient's quality of life. A Palliative Care Program has been developed at KFSH&RC, since 1991. This has broadened the spectrum of health services available to cancer patients. Palliative care needs to be more widely available in the kingdom to relieve an important cause of human suffering.

Magnetic resonance imaging of the shoulder: assessment of effectiveness

OBJECTIVES

To quantify how magnetic resonance imaging (MRI) influences clinicians' diagnosis, diagnostic confidence and management plans in patients with shoulder problems. To investigate whether such changes are associated with an improvement in health.

METHODS

A prospective observational study on all patients referred to a regional centre for MRI of the shoulder over a 6-month period. Data on diagnosis, diagnostic confidence and proposed management before MRI were compared with diagnoses and actual management after MRI. In addition, short form 36 item (SF-36) health survey data were collected at referral and again 6 months later.

RESULTS

In 86 of 99 MRI referrals there was sufficient clinical data for the patient to enter the study. MRI led to previously unsuspected diagnoses in 20 of 59 patients where the clinicians had provided full diagnostic information before and after the examination. When MRI confirmed the clinical diagnosis, significant improvements in clinicians' diagnostic confidence were found (P < 0.001). MRI led to a change in management (P < 0.05) in 44 (62%) of the 71 patients where full management plans were available. Health survey results were available in 62 patients; although there were some improvements in SF-36 scores, these did not reach statistical significance.

CONCLUSION

Magnetic resonance imaging of the shoulder significantly influences clinicians' diagnoses and management plans. However, patients do not record a statistically significant improvement in health-related quality of life over 6 months.

Trauma triage: a comparison of CRAMS and TRTS in a UK population

The CRAMS scale and the Triage Revised Trauma Score (TRTS) were compared to assess their potential use as a prehospital method of activating hospital trauma teams. We studied patients from the resuscitation room of Leeds General Infirmary who had enough data recorded to allow calculation of the admission TRTS and CRAMS scale. Patients were defined as having major injury if they died in hospital, were admitted to the ICU or had an Injury Severity Score (ISS) of > 15. Each triage scale was compared by calculating multiple sensitivity/specificity pairs and plotting the results on a receiver operator (ROC) curve. The optimal cut-offs on each scale were compared directly. Ninety-seven (46 per cent) of a total of 213 patients fulfilled the study criteria for major injury. The best cut-off points were a CRAMS of < 9 and a TRTS of < 12. The TRTS was significantly more specific (0.9 versus 0.75) but at a cost of poor sensitivity (0.6 versus 0.69, not significant). The performance of both scales was similar when compared on the ROC curve. CRAMS and the TRTS were unable to identify major injuries in our sample with sensitivity and specificity adequate to support their use as a tool to activate trauma teams in the UK.
