CRITERIA FOR BLOOD TRANSFUSIONS

A review of the use of blood transfusions used in a small community hospital over a two-year period revealed a high incidence of instances in which the clinical record did not show essential need for the procedure. Educational efforts in hospital staff meetings resulted in some improvement in this respect during the two-year period. Of single unit transfusions given during the first year, 80 per cent were deemed to have been nonessential; during the second year, 52 per cent.Methods which will reduce the use of blood except when it is essential are (1) continuation of staff education; (2) providing the staff with accurate methods of measurement of blood volume and of monitoring blood loss; (3) use of a separate blood transfusion chart in the patient''s hospital record; and (4) establishment of a hospital transfusion committee to review the criteria in all cases in which blood is transfused.     

"Homeward bound": a minimal care rehabilitation unit.

A 20 bed minimal care rehabilitation unit was set up by Newham District Health Authority in a small hospital originally scheduled for closure when a new district general hospital was opened. During the first year 114 patients were admitted (throughput 5.7), with a median length of stay of 30 days; in the second year 173 patients were admitted (throughput 8.65) with a median length of stay of 28.5 days. The cost per inpatient day was less than that of an inpatient day at the district''s long stay geriatric unit. Before the unit opened 24% of the acute beds had been occupied for more than six weeks, whereas two years later only 6% of the acute beds were occupied for such a period.     

Management of acute stroke in the elderly: follow-up of a controlled trial.

Follow-up of a controlled trial of the management of acute stroke in the elderly showed that the improvement in functional outcome at the time of discharge from hospital that had been achieved through establishing a stroke unit had disappeared by one year. Factors that might have contributed to this included overprotection by the families of patients who had been treated in the stroke unit, who were not permitted to carry out activities of daily living in which they were independent, and the early discharge from medical units of patients whose full rehabilitation potential had not been realised. Prolonging the benefits of short-term gains in functional outcome through the intervention of a stroke unit requires that all the links in the chain of stroke rehabilitation are maintained, including the proper orientation of patients'' families before discharge from hospital.     

Multi-purpose HealthCare Telemedicine Systems with mobile communication link support

The provision of effective emergency telemedicine and home monitoring solutions are the major fields of interest discussed in this study. Ambulances, Rural Health Centers (RHC) or other remote health location such as Ships navigating in wide seas are common examples of possible emergency sites, while critical care telemetry and telemedicine home follow-ups are important issues of telemonitoring. In order to support the above different growing application fields we created a combined real-time and store and forward facility that consists of a base unit and a telemedicine (mobile) unit. This integrated system: can be used when handling emergency cases in ambulances, RHC or ships by using a mobile telemedicine unit at the emergency site and a base unit at the hospital-expert's site, enhances intensive health care provision by giving a mobile base unit to the ICU doctor while the telemedicine unit remains at the ICU patient site and enables home telemonitoring, by installing the telemedicine unit at the patient's home while the base unit remains at the physician's office or hospital. The system allows the transmission of vital biosignals (3–12 lead ECG, SPO2, NIBP, IBP, Temp) and still images of the patient. The transmission is performed through GSM mobile telecommunication network, through satellite links (where GSM is not available) or through Plain Old Telephony Systems (POTS) where available. Using this device a specialist doctor can telematically "move" to the patient's site and instruct unspecialized personnel when handling an emergency or telemonitoring case. Due to the need of storing and archiving of all data interchanged during the telemedicine sessions, we have equipped the consultation site with a multimedia database able to store and manage the data collected by the system. The performance of the system has been technically tested over several telecommunication means; in addition the system has been clinically validated in three different countries using a standardized medical protocol.     

Legionnaires' disease caused by Legionella dumoffii in distilled water.

Five cases of Legionnaires'' disease caused by Legionella dumoffii were identified within an 11-month period in a hospital in the Quebec City area. In four cases bacterial isolates were obtained from clinical specimens, and in one case seroconversion was demonstrated. All the patients had been admitted to hospital within 10 days before diagnosis. Two of the patients were immunosuppressed children. Only 1 of the 40 hot water samples from the hospital yielded L. dumoffii; however, 6 of 11 distilled water samples contained the bacterium. All the patients had been exposed to distilled water, four through respiratory therapy equipment and one through a room humidifier. Following the use of sterile distilled water in the apparatus, no further cases were identified. This is the first reported outbreak of Legionnaires'' disease caused by L. dumoffii, and it is the first time that nosocomial legionellosis has been linked to contaminated distilled water in Canada.     

Smoking and lung cancer

The effectiveness of cardiopulmonary resuscitation as a vital aspect of health care delivery in hospital was the basis for a ten-year study. All instances of cardiac arrest occurring outside the operating room and nursery were included.Variations in degrees of success of cardiopulmonary resuscitation as related to the duration of the program, differences among varying subsets such as patients'' type of illness and hospital location (emergency room, coronary care unit, intensive care unit or nursing floor) at the time of cardiopulmonary arrest, are presented. The relationship between cardiopulmonary resuscitation frequency and success with increasing instrumentation is reviewed. A simple technique for expressing effect of cardiopulmonary resuscitation on hospital mortality is presented.The study shows the ability of a community hospital to establish, maintain and document a high level cardiopulmonary resuscitation program.     

Trauma services requirements in a district general hospital serving a rural area.

OBJECTIVE--To assess the demands made on a regional trauma centre by a district trauma unit. DESIGN--Two part study. (1) Prospective analysis of one month''s workload. (2) Retrospective analysis of one year''s workload by using a computer based records system. Comparison of two sets of results. SETTING--Accident unit in Gwynedd Hospital, Bangor. PATIENTS--(1) All patients who attended the accident unit in August 1988. (2) All patients who attended the accident unit in the calendar year April 1988-April 1989. MAIN OUTCOME MEASURE--Workload of a district trauma unit. RESULTS--In August 1988 there were 2325 attendances; 2302 of these were analysed. In all, 1904 attendances were for trauma; 213 patients were admitted to the trauma ward and 103 required an operation that entailed incision. Patients who attended the unit had a mean (range) injury severity score of 2-13 (0-25). Only two patients had injuries that a district general hospital would not be expected to cope with (injury severity score greater than 20). In the year April 1988-April 1989, 21,007 patients attended the unit. In all, 17,958 attendances were for orthopaedic injuries or injuries caused by an accident; 1966 patients were admitted to the unit. CONCLUSIONS--Most trauma is musculoskeletal and relatively minor according to the injury severity score. All but a few injuries can be managed in district general hospitals. In their recent report the Royal College of Surgeons has overestimated the requirements that a British district general hospital would have of a regional trauma centre.

Community care service for diabetics in the Poole area.

Because of an increasing work load at the hospital diabetic clinic in Poole general practitioners were asked to help in a community care service for diabetics. In this, general practitioners typically care for non-ketotic patients with maturity onset diabetes who are well controlled on diet or diet and oral hypoglycaemic agents, while the clinic concentrates on more difficult cases and screens patients for long-term complications. The hospital laboratory''s work load has been eased because patients may attend for two-hour interval blood sugar estimations when they like; most patients appreciate this flexibility and prefer being looked after by their own doctor. The service has not increased the general practitioners'' work load unduly, but it has heightened their awareness of diabetes in the community, thus allowing the diabetic consultant to deal with the problems for which he has been trained. The service has thus provided improved care for all diabetics in the Poole area.     

Cost of urology: financial audit in a clinical department.

OBJECTIVES--To cost a clinical unit over one month in 1991, to cost treatment of individual patients from audit data, and to compare this costing method with the hospital charging system. DESIGN--A financial breakdown was obtained for one month''s work. Ward stay, operating time, investigations, and outpatient visits were costed and a formula (episode = days on ward+hours of operating+investigations+outpatient visits) was used to cost patient episodes from audit data. SETTING--The adult urology unit in a teaching hospital. MAIN OUTCOME MEASURES--Costs for each part of patients'' treatment. RESULTS--Total cost was 147,796 pounds for 159 admissions, 738 inpatient days, 131 operations in 29 operating lists, and 615 outpatient visits. An uncomplicated transurethral prostatectomy cost 1140 pounds but complications increased this to 1500 pounds in another patient. The costs of diagnostic cystoscopy were 130 pounds in outpatients, 240 pounds in day surgery, and 430 pounds in inpatients. Hospital charges do not reflect the individual costs of treatment, charges being greater than costs for some patients and lower than costs for others. CONCLUSIONS--Clinicians can produce a financial analysis of their work and cost their patients'' treatment. Audit is strongly advocated as a resource planning tool.     

Training and Experience of Physicians in the Management of Adequate Anticoagulant Therapy

In a group of seven physicians engaged on a full-time basis in the anticoagulant unit of a teaching hospital, it was demonstrated that errors occur frequently in the management of anticoagulant therapy and that the incidence of such errors decreases during the course of the physician''s training period. Expert supervision and proper organization of the unit permit detection and correction of a high percentage of these errors.     

Accuracy of hospital activity analysis operation codes.

The accuracy of operation codes on hospital activity analysis printouts has been compared with unit and patient records. Inaccurate information is being provided by the hospital activity analysis in a significant number of cases. The same mistake is often repeatedly made, suggesting deficient monitoring procedures. These lapses occurred despite a unit policy of medical staff entering the operation and diagnostic details on the HMRI(IP) sheet and the checking of all entries by a consultant.     

Management of acute illness in infants before admission to hospital.

Parents and family doctors were questioned about the management of 150 infants with acute illness before their admission to hospital. When 108 of the children were first assessed the family doctor did not consider that admission was necessary, but follow-up was arranged in only 14 of these cases. Thus in 94 cases the initiative for recall was left to the parents, who in 44 cases already wanted their child to be admitted. Forty-eight infants were referred because the doctors thought that the parents could not cope. The parents of 31 of the children delayed in seeking help. As over half the children were ill for more than three days before they were admitted to hospital, regular follow-up could have been arranged. Doctors should normally retain the initiative for this rather than leave it to the parents'' discretion.     

Prospective pricing and DRGs.

In the Congenital Heart Program at San Diego Children''s Hospital, alterations in medical practice have reduced costs without impairing quality or access. Pediatric cardiac catheterization was done in 483 consecutive elective patients without overnight hospital stay. Hospital readmission was required in one patient for psoas tendinitis. Avoiding overnight hospital stay minimized attendant risks of hospital care, lessened psychosocial trauma and reduced the average hospital bill by $493 (29%). Hospital stay was also reduced for elective surgical correction of congenital heart disease on a case-by-case basis. Review of 151 consecutive cases (1978 through 1982) showed a decrease in both preoperative days in hospital and postoperative days in an intensive care unit. The duration of the postoperative stay was shortened from 6.8 days in 1978-1979 to 4.4 days in 1982 (P <.05). No increase in morbidity and no mortality resulted from the shortened perioperative hospital stay. Financial savings from this process averaged $991 per procedure.Diagnostic tests were reassessed and many precatheterization laboratory tests were eliminated. Without change in new patients seen or surgical volume, the use of cardiac catheterization decreased from 241 procedures in 1981 to 161 in 1982 and the number of operations without catheterization increased (11 to 22, 1981 to 1982). No increase in surgical morbidity or mortality was found comparing those diagnosed only by echocardiography with those who had preoperative cardiac catheterization. The decrease of 80 catheterizations in one year resulted in a savings of $188,800.True cost containment (reducing cost without reducing quality) can be accomplished in congenital heart programs. Similar cost containments in other disciplines may also be achieved.     

Area security unit in a psychiatric hospital.

Since 1974 a psychiatric hospital security unit, designed to serve the whole catchment area, has cared for mentally ill (mostly psychotic) patients with disturbed behaviour that cannot be managed in open wards. There are a few long-term dangerous patients but most stay only briefly. The admission of women to the unit was not followed by the expected reduction in violence. The unit has facilities for occupational therapy, physical recreation, work, and study, which are particularly important for those who are too dangerous to leave it. The unit''s calming influence depends as much on the supportive effect of the high staff ratio as on the use of tranquillisers. This type of unit is not suitable for patients with personality disturbances who "act out" or for mentally abnormal offenders; but it functions well as a crisis centre for the disturbed mentally ill, and there is an increasing demand for its services.     

Comparative Study of District and Community Hospitals

Opinions conflict on whether there is a place in the Health Service for general practitioner (community) hospitals in which the patients'' treatment is mainly the responsibility of their family doctors. The authors therefore analysed a sample of the patients admitted in the course of a year to a group of two general district hospitals with a comparable sample of the patients admitted to a general practitioner hospital. The aim was to analyse the type of care provided in the general practitioner hospital, to assess whether it was appropriate for the type of cases treated, and to decide whether the patients would have been better off in the district general hospital (and vice versa). The main conclusions are that a district hospital is best for serious illnesses needing skilled decisions and assessments but that most of the work of these hospitals is not of this kind and a community hospital staffed by general practitioners offers many advantages to patients—provided the work being done is constantly under critical assessment. The authors plead for special refresher courses under the N.H.S. for general practitioners working in community hospitals.     

Predicting child abuse: signs of bonding failure in the maternity hospital.

Fifty children referred to the Park Hospital because of actual or threatened abuse were compared with 50 controls born at the same maternity hospital. Five factors were significantly more common in the abused group than among their controls: (a) mother aged under 20 at birth of first child, (b) evidence of emotional disturbance, (c) referral of family to hospital social worker, (d) baby''s admission to special care baby unit, (e) recorded concern over the mother''s ability to care for child. Thirty-five of the abused group had two or more of these factors compared with only five of the control group. As these data were collected from information recorded routinely at the maternity hospital, it is possible to identify most abusing families when the child is born. Such identification must lead to a comprehensive assessment of each case followed by constructive preventive action.     

Effectiveness of the Quick Medical Reference as a diagnostic tool

A number of computer-based systems with diagnostic capabilities have been developed for internal medicine. Quick Medical Reference (QMR) is one such program. The authors describe key features of QMR and report on their study of its effectiveness as a diagnostic tool. They investigated how frequently the correct diagnosis would appear among the 5 highest ranked diagnoses generated by QMR. The charts of 1144 consecutive patients admitted to a teaching unit were retrospectively screened. Eligible cases included those referred for investigation of an undiagnosed illness with an objectively proven final diagnosis (n = 154). Two physicians familiar with, but not experts in, the use of QMR entered clinical information abstracted from the patients'' charts into the program. Physician A obtained the correct diagnosis in 62 (40%) of the 154 cases, and physician B was successful in 56 (36%) of the cases. The authors use study cases to illustrate QMR''s strengths and weaknesses.     

A Taxonomy of Continuing Medical Education Endeavour

Five basic forms of continuing educational endeavour by physicians are listed in rank order. These components constitute an indivisible unit bound together by self-learning. The scholarly habit of planned daily reading and study in a home library-sanctuary as an integral part of a physician''s workday heads the list. Day-to-day informal and formal colleague-association in patient care in the community and teaching hospital, in group practice and by consultation is the present major form of continuing educational endeavour. Emphasized is the sabbatical return every three to five years for three months at least to the teaching hospital to reinforce scholarly motivation and attitudes and to acquire new skills and knowledge. Attendance at scientific sessions of learned professional societies and short courses should be accompanied by presession and post-session guided reading to be undertaken in the physician''s home library-sanctuary.     

Effectiveness of neonatal transport.

The condition of 259 infants transferred to the neonatal intensive care unit (NICU) of the Montreal Children''s Hospital from Oct. 1, 1974 to Mar. 31, 1975 was evaluated. Their transport was provided by personnel and equipment from the Montreal Children''s Hospital. When the transport team arrived at the referring hospital hypothermia (temperature of less than 36 degrees C) was present in 25.2% of the 163 infants for whom complete temperature measurements were available. Most (77.3%) of the infants were warmed during transport and only 3.1% arrived at the NICU with a temperature of less than 35 degrees C. The mortality was significantly higher in babies of all birth weight groups whose core temperature had been below the optimal temperature for survival (36 to 37 degrees C). It appears that the use of appropriate equipment and trained personnel can reduce the incidence of hypothermia and therefore the mortality in infants requiring transfer.
