Early active mobilization for extensor tendon injuries. The Norwich regime

Dynamic splinting following extensor tendon repair gives better results than static splinting, but involves cumbersome splints and recommended protocols are often complicated. We prefer controlled active mobilization of extensor tendon repairs without dynamic splinting. Six weeks after repair, excellent or good function was obtained in 22 out of 24 simple extensor tendon injuries and in 11 out of 13 complex injuries. The results of this prospective study are comparable with those reported after dynamic splinting; this regime does not require outrigger splintage and is simple to follow.     

The effects of an outpatient practice guideline at a teaching hospital: a prospective pilot study

BACKGROUND: Platelet-activating factor (PAF) is a bioactive phospholipid which is a potent hypotensive agent. To investigate the role of PAF in renovascular hypertension, we determined the PAF concentration and its production level assessed by the activity of cholinephosphotransferase (CPT) in renal tissue and examined the effect of a PAF antagonist on the mean arterial pressure (MAP) in control and two-kidney with one clipped (2K1C) hypertensive rats. MATERIALS AND METHODS: The concentration of PAF and CPT in the renal medulla and cortex were determined by radioassay. Also, the effect of a PAF antagonist, CV-6209, on MAP was also examined in both 2K1C hypertensive and normal control rats. RESULTS: The PAF concentration and CPT activity were significantly higher in the medulla than in the cortex in both 2K1C hypertensive and normal control rats, and both values in the medulla were also significantly higher in the clipped kidney than in the contralateral unclipped kidney or in control rat kidneys. We also observed a significant negative correlation between the PAF concentration in the medulla, and the medulla weight in the clipped kidney of 2K1C hypertensive rats. Infusion of the PAF antagonist, CV-6209, did not affect MAP in 2K1C hypertensive rats, but was significantly increased (P < 0.05) in control rats. CONCLUSIONS: These findings suggest that PAF, whose production is induced by renal ischemia due to renal artery stenosis, plays an important role in the renomedullary vasodepressor system, but the effect of PAF as a vasodilator in the peripheral vessels is limited in 2K1C hypertension.     

The effectiveness of hospital at home compared with in-patient hospital care: a systematic review

As nitric oxide (NO) may be a particularly important vasodilator in early life, we investigated its role in the regulation of the gastrointestinal (GI) circulation at mid-gestation. Cardiac output and GI blood flow were measured by the radioactive microsphere technique in eight chronically instrumented and unanesthetized mid-gestation fetal sheep. Mean arterial pressure (MAP), heart rate, blood flow, oxygen delivery, and vascular resistance were determined before and after infusion of the specific NO synthase inhibitor, Nomega-nitro-L-arginine (L-NNA) at doses of 10 and 25 mg/kg. In response to L-NNA infusion, MAP increased (p < 0.01) and combined ventricular output decreased (p < 0.001). GI blood flow and oxygen delivery decreased and vascular resistance increased in the stomach and all segments of the small and large intestine (all p < 0.001). The greatest reduction in blood flow was in the small intestine (p < 0.01) and the basal differential pattern of small intestinal blood flow exceeding large intestinal flow was completely abolished. These changes were much greater than those previously described in late-gestation fetuses. Our results suggest that, at mid-gestation, NO plays a major role in the regulation of blood flow and vascular tone across all segments of the fetal GI tract, with its effects being more pronounced than later in development.     

The aging psychiatric hospital: an approach to humanistic redesign

Since funds for the construction of new treatment facilities are scarce, outmoded wards must be redesigned to meet the current needs of users. The authors feel the redesign must integrate modern therapeutic concepts, humanistic patient requirements, and pragmatic budgetary limitations. They review current theory about the effects of the physical environment on behavior, and they discuss such questions as to what extent the need for security should govern ward design and how pleasant the environment should be. They also describe a specific redesign for a 32-bed psychiatric ward of a large federal hospital constructed in the early 1950s.     

Treatment of aggression for an adult diagnosed with schizophrenia at a public psychiatric hospital.

The effectiveness of a behavioral program to treat chronic aggression in an adult male individual diagnosed with schizophrenia at a public psychiatric hospital was evaluated. A behavioral plan was developed to provide the client with positive social interactions, social skills training, and positive reinforcement for prosocial behavior; no negative consequences were implemented. The number of aggressive acts declined with the introduction of the behavioral plan and ultimately remitted even without ongoing reinforcers. This article demonstrates the value of psychological intervention in treating aggression with a treatment-resistant client in an in-patient setting.

Extended-spectrum beta-lactamases from Klebsiella pneumoniae strains isolated at an Italian hospital

Eighteen strains of Klebsiella pneumoniae recently isolated from hospitalized patients were resistant or moderately resistant to oxyimino-cephalosporins (ceftazidime and/or cefotaxime), aztreonam, cefoxitin and all but one were susceptible to imipenem. Analysis of enzymes produced by these clinical isolates revealed a wide pattern of extended-spectrum beta-lactamases. All isolates produced one or more beta-lactamases that were characterized preliminarily by their isoelectric point. Strains isolated early were from patients in the Intensive Care Unit and produced an ES beta-lactamase with an apparent pI of 7.6, whereas the later isolates were from surgical and medical wards of the same hospital and produced ES beta-lactamases with apparent pI of 8.2 and 8.4, respectively. This suggests the emergence of SHV-5 and MIR-1 beta-lactamases in our hospital. Agarose gel electrophoresis of plasmid DNA revealed the presence of a similar plasmid of approximate size 60 Kb in all isolates.     

Maintaining a smoke-free policy: an observational and interview study at a university hospital in Sweden

Strategies directed against activated neutrophils have reduced ischemia-induced brain injury. However, therapies targeted specially against the neutrophil adhesion protein L-selectin have not yet been examined in stroke. This study therefore examined the effects of a monoclonal antibody directed against L-selectin in a rabbit model of thromboembolic stroke with (n = 16) or without (n = 10) concomitant t-PA therapy. Rabbits received either the humanized monoclonal antibody DREG200 directed against the L-selectin receptor or humanized control monoclonal antibody HuDREG55 which does not bind to rabbit L-selectin in addition to t-PA therapy (n = 8, each group). HuDREG200 (2 mg kg-1 i.v.) was given as a bolus 3 h following clot embolization, followed immediately by a 2 h intravenous infusion of t-PA (6.3 mg kg-1. Without t-PA therapy rabbits received HuDREG200 (2 mgkg-1, i.v.; n = 5) or HuDREG55 (n = 5) 1 h following clot embolization. The group receiving HuDREG200 in addition to t-PA demonstrated a moderate improvement in brain infarct size (8.4 +/- 2.4 vs. 13.5 +/- 3.5, %hemisphere, mean +/- sem), ICP (final reading 10.0 +/- 1.6 vs. 12.4 +/- 3.0 torr) and restoration in regional cerebral blood flow (30.2 +/- 7.8 vs. 21.6 +/- 10.9 cc 100 g-1 min-1) when compared to t-PA therapy alone although statistical significance was not achieved. No efficacy was demonstrated in the group receiving HUDREG200 without concomitant t-PA therapy. The results suggest the addition of a humanized anti-L-selectin monoclonal antibody HuDREG200 in combination with t-PA may further improve outcome in acute thromboembolic stroke, although future studies are necessary to support these findings.     

The treatment of peptic ulcer patients during exacerbation at the day hospital of an industrial enterprise polyclinic

Results are submitted of treatment of 659 patients with exacerbated peptic ulcer at an in-plant day in-patient facility. The basic therapy was hyperbaric oxygenation and ultraviolet irradiation of blood. The relapse rate over the year was 16%. A surgical operation was performed in 1.5% of those cases having completed the course treatment at the day in-patient facility, with 33.3% of patients having been operated on urgently, and 11.28% at a twenty-four-hour department; of these, in 85.62% cases operations were performed in situations of emergency needing prompt action. Duration of temporary disability in patients cared for at the day hospital was 21.3 days, while in those treated at a twenty-four-hour facility-27.8 days. Indications for hospitalization were of social character. Comparison of results of treatment, relapse rates and complications of ulcer disease in hospitalized patients versus those having been treated at a day-care facility gave arguments in favour of reorientation of treatment of major part of those patients experiencing exacerbation of ulcer disease at well equipped day-care in-patient facilities.     

Acupuncture in a university hospital: implications for an inpatient consulting service

The novel phospholipid 2, which bears a tert-butyl moiety in place of the natural trimethyl ammonium group of phosphatidylcholine, has been enzymatically synthesized via a transphosphatidylation reaction mediated by phospholipase D. The change from the choline headgroup in 1 to the tert-butyl group in 2 reduced the efficiency of hydrolysis by the phosphatidylcholine-preferring phospholipase C from Bacillus cereus by a factor of greater than 10(3).     

Special care for newborns at a community hospital: a 5-year experience

Anthralin has been a consistently effective drug for the treatment of psoriasis for more than 80 years, but has not enjoyed common use in the United States because of the unwanted side effects of irritation and staining. New treatment methods such as short-contact therapy and innovative vehicle formulations minimizing these problems have allowed anthralin once again to be used effectively in psoriatic treatment programs. We review these newer adaptations and suggest that the enduring modality deserves an important place in the topical armamentarium.     

A new method of infant monitoring: for use at home and hospital

AIM: To test a New Zealand originated, designed and funded remote infant heart rate monitor in the home and hospital settings (temporarily named the King Monitor) for accuracy and reliability. METHODS: The units were pretested using ECG simulators and on infants already being monitored in the neonatal unit. Longer term trials on hospital infants and infants being simultaneously monitored at home were then conducted. RESULTS: Interference and electrode problems were corrected during the pretesting phase. The unit worked accurately when compared with the standard neonatal heart and respiratory rate monitor in hospital and appeared in some infants to give earlier warning of problems than the standard home apnoea monitor. CONCLUSION: This simple to use monitor worked reliably and accurately under a wide variety of settings and with varying sized infants. In addition, the lack of direct connection between the infant and the control unit allowed freedom of movement of normal infants around the cot or bassinet. The monitor will require to be adapted for portable use at home and during travel.     

The Medical Polyclinic: an approach to conflicting needs in a teaching hospital

University teaching hospitals have become increasingly aware of their responsibility to improve both the teaching of ambulatory care and the quality of care provided in their clinics. This paper describes how one department of medicine met this challenge by forming a "Medical Polyclinic." The majority of the department's faculty and house staff, at all academic and training levels, participate in a system of ambulatory care with the following objectives: each patient has a single physician whom he sees by appointment and who coordinates his care; all medical subspecialties are available in the same clinic session; the clinic is attractive and efficient. While these goals are not infrequently met in private group practices, they are unusual in a university teaching hospital, where faculty, house staff, students, and patients each have unique needs, not always compatible. The success and problems of the polyclinic approach are discussed.     

Personal watercraft injuries: experience at a community hospital

A 16-month retrospective review was performed of patients brought to Lake of the Ozarks General Hospital Emergency Department for treatment of injuries suffered in personal watercraft accidents. Fourteen of 37 patients showed clinical and radiographic evidence of fractures or internal injuries. Personal watercraft accidents are a significant cause of morbidity in a lake resort community population.     

The cost of caring for end-stage kidney disease patients: an analysis based on hospital financial transaction records

The costs of care for end-stage renal disease patients continue to rise because of increased numbers of patients. Efforts to contain these costs have focused on the development of capitated payment schemes, in which all costs for the care of these patients are covered in a single payment. To determine the effect of a capitated reimbursement scheme on care of dialysis patients (both hemodialysis [HD] and peritoneal dialysis [PD]), complete financial records (all reimbursements for inpatient and outpatient care, as well as physician collections) of dialysis patients at a single medical center over 1 year were analyzed. For the period from July 1994 to July 1995, annualized cost per dialysis patient-year averaged $63,340, or 9.8% higher than the corrected estimate from the U.S. Renal Data Service (USRDS; $57,660). The "most expensive" 25% of patients engendered 44 to 48% of the total costs, and inpatient costs accounted for 37 to 40% of total costs. Nearly half of the inpatient costs resulted from only two categories (room charges and inpatient dialysis), whereas other categories each made up a small fraction of the inpatient costs. PD patients were far less expensive to care for than HD patients, due to reduced hospital days and lower cost of outpatient dialysis. Care for a university-based dialysis population was only slightly more expensive than estimates predicted from the USRDS. These results validate the USRDS spending data and suggest that they can be used effectively for setting capitated rates. Efforts to control costs without sacrificing quality of care must center on reducing inpatient costs, particularly room charges and the cost of inpatient dialysis.     

Constipation: cause and control in an acute hospital setting

Constipation is not a glamorous subject, but its prevention and management can make a vast difference to patients' quality of life. This literature review identifies causative factors and describes the mode of action, side-effects and contraindications of many remedies currently available. Recommendations include a systematic approach to management in an acute ward setting, based on assessment of risk, maintenance of normal bowel routine and appropriate dietary advice and the use of appropriate pharmaceutical interventions where necessary. To be effective, this process should be underpinned by accurate documentation and the maintenance of a high level of knowledge and awareness among staff.     

The community hospital: a three-year study

In a three-year period a community hospital of 40 beds discharged 2086 patients, their mean length of stay being 14.8 days. Some 68% of the patients treated were over 65, and 8.9% died in hospital. While the most common diagnosis on admission was disease of the respiratory tract, this does not indicate the actual cause of admission. For 142 patients from one practice this was acute illness in 44% of the cases, assessment in 20%, and a need for nursing care in 36%. If the community hospital had not been available about half these patients would have been admitted to the general hospital.     

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.
