Multisystemic Treatment of Substance-Abusing and -Dependent Delinquents: Outcomes,Treatment Fidelity,and Transportability

The effectiveness and transportability of multisystemic therapy (MST) were examined in a study that included 118 juvenile offenders meeting DSM-III-R criteria for substance abuse or dependence and their families. Participants were randomly assigned to receive MST versus usual community services. Outcome measures assessed drug use, criminal activity, and days in out-of-home placement at posttreatment (T2) and at a 6-month posttreatment follow-up (T3); also treatment adherence was examined from multiple perspectives (i.e., caregiver, youth, and therapist). MST reduced alcohol, marijuana, and other drug use at T2 and total days in out-of-home placement by 50% at T3. Reductions in criminal activity, however, were not as large as have been obtained previously for MST. Examination of treatment adherence measures suggests that the modest results of MST were due, at least in part, to difficulty in transporting this complex treatment model from the direct control of its developers. Increased emphasis on quality assurance mechanisms to enhance treatment fidelity may help overcome barriers to transportability.     

Vertical Banded Gastroplasty Versus Standard or Distal Roux-en-Y Gastric Bypass Based on Specific Selection Criteria in the Morbidly Obese: Preliminary Results

Background: Predicting successful outcomes after bariatric surgical procedures has been difficult, and the establishment of specific selection criteria has been a subject of ongoing research. In an effort to choose the most appropriate surgical procedure for each patient, we have established a specific set of selection criteria for each procedure based on degree of obesity, preoperative dietary habits, eating behavior, and various metabolic features. Methods: From June 1994 to December 1998, 90 bariatric surgical procedures were performed at the authors' institution by a single surgeon (F.K.) based on specific selection criteria. Vertical banded gastroplasty (VBG) was performed in 35 patients, standard Roux-en-Y gastric bypass (RYGB) in 38 patients, and distal RYGB in 17 patients. All patients were monitored postoperatively 1, 3, 6, and 12 months and once per year thereafter, with an additional visit at 18 months in distal RYGB patients. Results: Early postoperative morbidity (<30 days) did not differ significantly between the three groups and averaged 9% of total patients. Long-term postoperative morbidity (>30 days) included 9 incisional hernias (2 in the VBG group, 5 after RYGB, and 2 in the distal RYGB group). There were 6 cases of staple-line disruption, 4 after VBG and 2 after standard RYGB, 1 of which resulted in stomal ulcer. Early postoperative mortality was 0%, and long-term mortality was 1.1%, which was due to pulmonary embolism in 1 standard RYGB patient on the 65th postoperative day. Average percentage of excess weight loss (%EWL) was 62% the first year, 61% the second year, and 50% the third year in VBG patients, and 63.6%, 65%, and 63.3%, respectively, in standard RYGB patients. In distal RYGB patients, where the patient number was significantly smaller, the %EWL at 1 and 2 years, respectively, was 51% and 53%. The most significant metabolic/nutritional complication was the appearance of hypoproteinemia (hypoalbuminemia) in 1 distal RYGB patient 20 months after surgery, which was corrected by total parenteral nutrition and subsequent increase in dietary protein intake. Significant improvement or resolution of pre-existing comorbid conditions was observed in all patient groups. The postoperative quality of eating, as evaluated by variety of food intake and frequency of vomiting, was significantly better in RYGB patients. Conclusions: These results show that selection of the bariatric surgical procedure to be performed in each patient based on specific criteria leads to acceptable weight loss, improvement in preexisting comorbid conditions, and a high degree of patient satisfaction in most patients. On the basis of our own observations as well as those of others, our selection criteria have become more strict over time and our selection of VBG as the operation of choice increasingly infrequent.     

Surgical Resection and Intraperitoneal Chemotherapy for Recurrent Abdominal Sarcomas

Background: Recurrent abdominal sarcomas have an extremely high rate of recurrence and poor overall survival. A prospective study was initiated to assess the feasibility, toxicity, and benefit of surgical resection and intraperitoneal chemotherapy for improving local control of disease and overall survival.Methods: Fifty-four patients underwent surgical excision of all gross disease and postoperative intraperitoneal chemotherapy with mitoxantrone. Thirty-five patients had peritoneal disease only (stage II), and 19 patients had peritoneal disease with hepatic metastases (stage III).Results: Nine (17%) patients remain free of disease with a mean follow-up of 37 months. The remaining 45 patients (83%) have had recurrence, with a mean interval to recurrence of 11 months. Stage (P 5.001) and grade (P 5.005) were the only two variables found to significantly affect recurrence. There was an overall peritoneal recurrence rate of 48% and an overall hepatic failure rate of 69%. Nineteen (35%) of the patients are alive, with a mean follow-up of 46 months. The overall 5-year survival was 31%. The 5-year survival for stage II patients was 46%; for stage III patients, it was only 5%. Stage (P 5.001) and grade (P 5.056) were the only two variables found to significantly affect survival. There were no treatment-related deaths, and only 5 patients (9%) developed local complications.Conclusions: Aggressive surgical resection and intraperitoneal chemotherapy for recurrent abdominal sarcomas is a feasible treatment approach with minimal toxicity. Although this treatment had little effect on the hepatic spread of this disease and thus overall survival, it appears to have significantly lowered the rate of peritoneal recurrence and may provide a survival benefit for patients with disease limited to the peritoneum.     

The effects of shifts in the balance of care on general practice workload.

BACKGROUND: The consequences of the move towards a primary-care-led NHS are shifts in activity from secondary care to primary care and more involvement of GPs in purchasing decisions. Although there are many anecdotal reports of an increasing primary care workload, there is little empirical evidence on the extent of such shifts. This paper reports the results of a survey of GPs in Grampian, in the north-east of Scotland, in which we attempted to gather information on the effects of shifts in the balance of care on general practice. OBJECTIVE: We aimed to examine GPs perceptions of the extent to which general practice workload has changed due to planned and unplanned shifts in the balance of care. METHODS: The design of the study was a self-reported questionnaire, which was administered in general practices in the Grampian Health Board, Scotland. The subjects were senior partners of all general practices and the main outcome measures were the types of changes which have taken place in general practice, their source, their effect on practice workload and how practices have reacted. RESULTS: A 60% response rate was achieved (52/86); 85% (44/52) of GPs claimed that their workload had increased due to shifts in the balance of care and that 72% of the shifts were initiated outside the practice. Geriatric care, early discharge and psychiatric and psychology services, as well as nursing home care, were reported to have had the greatest impact on workload. The main aspects of practice workload which had increased included the number of GP consultations, general stress at work and number of home visits, whereas the net income of the practice and health outcome of patients were reported to have decreased. Practices have dealt with the increase in workload by shifting tasks from GPs to nurses and absorbing the workload into existing practices/patterns. Responders reported that ideally more nursing and GP staffing would be required. Overall, GPs welcomed the shifts in the balance of care, were more concerned about poor communication rather than actual increases in workload and claimed that morale had fallen. CONCLUSION: GPs perceive that the move towards a primary-care-led NHS is increasing the workload in general practice. If the shift in the balance of care away from secondary care is to be successful, then more information is required about such shifts to support practices as change continues.     

Mild illness at or after measles vaccination does not reduce seroresponse in young children

We analyzed data from a randomized trial of AIK-C, high-titre (EZ-H) or medium-titre EZ (EZ-M) vaccines in 3.5 and 6 month old infants in Kinshasa, Zaire, in which the occurrence of rhinorrhoea, cough, diarrhoea, fever, conjunctivitis or rash was monitored for 15 days post-vaccination (including the day of vaccination, day 0). We compared sero-response at 6 weeks and 6 months post-vaccination among children with and without mild illness at or after vaccination. Seroresponse tended to be higher in children with mild illness after vaccination than those without, whether days 0-7 or 8-15 were examined. For most symptoms, these differences did not reach statistical significance after adjusting for prevaccination maternal antibody level. However, in the EZ-M group, the proportion of children attaining at least the median post-vaccination antibody level was significantly higher in children with rhinorrhoea in days 0-7 post-vaccination than those without (adjusted odds ratio 2.6, 95% CI 1.08-6.27), as was that among children with at least one symptom in days 0-7 compared with children with no symptoms (adjusted OR 4.55, 95% CI 1.18-17.57). There were no significant differences in post-vaccination antibody levels among children with symptoms compared either to those without the specific symptom or those with no symptoms. Fever on the day of vaccination or at home visits on 7, 10 or 14 days post-vaccination, did not affect seroconversion or GMTs. Regression models showed no relation between the cumulative number of days with symptoms and antibody increase after vaccination. Analysis of antibody levels at 6 months post-vaccination showed no consistent differences according to presence or absence of symptoms. These findings provide further strong support to recommendations that mild illness is not a reason to delay measles vaccination.     

Total purchasing, community and continuing care: lessons for future policy developments in the NHS

The introduction of total purchasing pilots (TPPs) into the National Health Service (NHS) gave general practitioners (GPs) significant new opportunities to take responsibility for the development of community and continuing care (CCC) services. Based on five case studies of TPPs involved in developing CCC this paper asks three questions: (1) to what extent were the TPP’s involvement in CCC informed by an awareness of CCC policy?; (2) were TPPs involved in joint commissioning to develop integrated purchasing or provision which was informed by population based needs assessment?; (3) were TPPs seeking to involve users, carers and voluntary agencies in their plans? The findings indicate that TPPs showed little awareness of national or local policy for CCC, although their project initiatives did address some of the policy issues (in particular a recognition of the need for joint working at the practice level). At the time of fieldwork, four of the case study TPPs had begun to investigate the potential for integrated purchasing, and three of them had relatively sophisticated models of both horizontally and vertically integrated provision of care. However, the TPPs developments were not based on systematic population based needs assessment. The paper concludes that there is potential for the primary care led groups proposed in the recent white papers in England, Scotland and Wales to improve integration of care both horizontally and vertically. However, they may need policy guidance and push to: encourage them to put CCC high on their agenda for action; to work with people with expertise in population based, prevention focused, needs assessment; and to find innovative ways to include users, carers and voluntary agencies. Incentives or levers (such as control over budgets) may be needed to promote joint working between staff in different agencies.
