Screening for psychosis risk in primary mental health care services - Implementation, prevalence and recovery trajectories.

OBJECTIVES: Early interventions improve outcomes for people at high risk of psychosis and are likely to be cost saving. This group tends to seek help for emotional problems - depression and anxiety - via primary care services, where early detection methods are poor. We sought to determine prevalence rates of high risk for psychosis in UK primary care mental health services and clinical outcomes following routinely delivered psychological therapies. METHODS: We used a brief screen designed for settings with low base rates and significant time constraints to determine prevalence of high risk for psychosis in UK 'Talking Therapies' services. We examined socio-demographic characteristics, presenting problems and recovery trajectories for this group, compared with people not at risk of psychosis. RESULTS: A 2-item screen selected for specificity yielded a prevalence rate of 3% in primary care mental health services. People at elevated risk of psychosis were younger and more likely to report at least one long-term physical condition. This group presented with higher levels of depression, anxiety and trauma symptoms at assessment and were less likely to have recovered at the end of treatment, compared to people not at risk. CONCLUSIONS: Very brief screening tools can be implemented in busy health care settings. The 3% of referrals to UK primary care psychological therapies services at elevated risk of psychosis typically present with more severe symptoms and greater levels of comorbidity and may require augmented interventions to recover fully.

Decrease in infections with the introduction of mupirocin cream at the peritoneal dialysis catheter exit site.

UNLABELLED: Staphylococcus aureus associated peritonitis and catheter exit site infections (ESI) are an important cause of hospitalization and catheter loss in the patients undergoing chronic peritoneal dialysis (PD). We aimed to determine the potential effectiveness of the application of mupirocin cream at the catheter exit site in preventing exit site infection and peritonitis. METHODS: This prospective historically controlled study was done in a total of 86 patients who entered our PD program from April 1999 to January 2001. They were instructed to apply Mupirocin cream 2% to the exit site daily or on alternate days. The patients were not screened to determine whether they were staphylococcus aureus carriers. One hundred and thirteen patients on PD prior to April 1999 acted as historical controls. Both groups were followed prospectively for a period of 22 months. RESULTS: In the study group application of mupirocin lead to a significant reduction in the incidence rate of both exit site infections overall (0.43 vs. 0.09; p<0.0001) and ESI due staphylococcus aureus (0.14 vs. 0.02; p=0.004) amounting to a relative reduction of 79% and 85% respectively. Although the overall incidence of peritonitis did not change (0.28 vs. 0.26; p=0.7) there was a significant reduction in peritonitis caused by staphylococcus aureus (0.07 vs. 0; p=0.01) Although only one catheter required removal in the mupirocin group as against 5 in the control group, this was not statistically significant. CONCLUSIONS: Mupirocin application at the exit site significantly lowers the incidence of ESI and peritonitis caused by staphylococcus aureus without any significant side effects.
