Managed mental health care: problems and possibilities

Case management has become an established organizational approach to mental health care. However, a recent development of case management, known as 'managed care' has received only limited attention in the UK and this has been confined to acute medical or surgical hospital care. The potential of managed care as applied to mental health care is uncertain. This paper clarifies the nature of managed care and discusses its relevance to mental health care, in particular to the care of people suffering from schizophrenia. The high incidence and heavy resource demands of this user group makes these people an ideal focus for managed care. However, there are conceptual and practical problems hindering its development and implementation, including: the variability and unpredictability of the disease process of schizophrenia; challenges of outcome measurement; and problems relating to the current organization of mental health care.     

The relation between the need for intubation at birth, abnormal cardiotocograms in labour and cord artery blood gas and pH values

Summary. A consecutive series of 56 infants of 32 weeks gestation or more who were resuscitated at birth by endotracheal intubation was studied to determine the occurrence of abnormal cardiotocograph traces and acidosis as determined by cord artery blood measurements. Thirty-two infants (57%) had neither cardiotocographic abnormalities nor acidosis; in this group the factors associated with the need for intubation were meconium stained amniotic fluid, operative delivery, anaesthetic agents given to the mother, a tight nuchal cord, and traumatic vaginal delivery. The need for intubation at birth should not automatically be regarded as evidence of intrapartum hypoxia or disturbed acid-base balance.     

Assessment of proton nuclear magnetic resonance spectroscopy for detection of malignancy

Water-suppressed proton nuclear magnetic resonance spectra were generated (by using 360 and 500 MHz systems) from human plasma and serum samples taken from 35 apparently healthy individuals, 52 patients with overt malignancies, and 37 patients with hypertriglyceridemia (triglycerides greater than 200 mg/dL or 2.26 mmol/L). The line widths from the lipoprotein-lipid methylene and methyl resonances at approximately 1.3 and 0.9 ppm were averaged by the method of Fossel et al. (N Engl J Med 1986;315:1369-76), but, contrary to their findings, we were unable to distinguish normal individuals from those with malignant tumors (e.g., mean +/- SD line width at 360 MHz: normal group = 32.9 +/- 3.6 Hz, malignant group = 28.3 +/- 4.9 Hz). The average line-width measurements (y), however, varied with the triglyceride content (x, mg/dL) of the plasma or serum as follows (logarithmic transformation of the data determined at 360 MHz and regression analysis): y = 110 (x-0.27). Data from both nonmalignant and malignant specimens fit this equation, the coefficient of correlation being -0.91. These findings suggest that considerable caution should be used in interpreting water-suppressed proton NMR spectra for cancer detection.     

P07Reduction of Allogeneic Red Cell Transfusion using Autologous Blood Cell Salvage in Knee Arthroplasty

Recent Hospital Transfusion Committee (HTC) audit at the Royal Bournemouth Hospital (RBH) confirmed an allogeneic red cell transfusion rate of 20% for primary Total Knee Replacement (TKR). Current policy at RBH states that when blood stocks reach 67% of normal (amber alert) then surgery with a >20% likelihood of blood transfusion will be cancelled. At current transfusion rates this would include primary TKR. Recent studies have shown a reduction in allogeneic transfusion rates when autologous transfusion drains are utilized. The purpose of this study was to see whether the current rate of allogeneic transfusion could be reduced with the introduction of the CellTransTM Autologous Knee Drainage Blood Transfusion System (ABT) in TKR at RBH. Over a 3 month period all patients undergoing primary, bilateral or revision knee arthroplasty received an ABT. Demographic data was collected from the orthopaedic pre‐assessment clinic. Following surgery further data was collected relating to volume of blood loss into the drain, volume of autologous blood re‐transfused, units of allogeneic blood required and the transfusion trigger, postoperative haemoglobin levels, infection rates and length of stay in hospital. We then compared this data set with retrospective data. Of 170 patients undergoing knee arthroplasty 141 received the ABT. The data collected was compared retrospectively with 169 patients from the previous 3 month period. We demonstrated a reduction in transfusion rates of 13% for primary TKR, 42% for bilateral TKR and 57% for revision TKR with the use of the ABT. In addition we demonstrated a reduction in total allogeneic blood use (99 units to 26 units) and a reduction in mean length of stay in hospital (8.6 days to 7.5 days) with the ABT. Further analysis of the data collected showed a 46% reduction in the allogeneic transfusion rate and a reduction in total allogeneic blood usage (99 units to 9 units) of anaemic patients presenting for surgery. This study has demonstrated a dramatic reduction in allogeneic blood transfusion rates with the use of the CellTransTM Autologous Blood Transfusion System. We have also shown a reduction in length of stay in hospital. Prior to the study primary total knee replacement would have been cancelled during times of limited blood availability (amber alert). The use of the ABT is good for the patient in reducing the need for allogeneic blood, and in addition has demonstrated a significant cost saving due to the reduced blood usage and potential prevention of cancelled operation lists.     

Fetal heart rate monitoring by telephone. I. Development of an integrated system in Cardiff

Summary. We report the development of a practical dedicated system for domiciliary fetal monitoring integrated in a scheme for its rational application. From experience of 1120 domiciliary recordings in 74 women (64 with high-risk pregnancies), we suggest that domiciliary monitoring applied within a structured clinical context should be as safe as monitoring in hospital.
