A Test to Detect Chest Tube Kinking

Objectives: To determine whether the Mac‐technique test can detect kinking of the chest tube upon thoracostomy tube placement. Methods: This was a prospective observational study that was conducted October 2000 through October 2001 in an urban Level 1 trauma center. There were 103 consecutive nonrandomized adult trauma patients who required immediate tube thoracostomy during their initial resuscitation who were entered into the study. The Mac‐technique test was performed during standard tube thoracostomy insertion to the appropriate depth. The test involved grasping the external portion of the thoracostomy tube, turning it clockwise 180°, and then releasing the tube. If the tube spontaneously spun back to its original position, the test was considered positive, and the tube was considered kinked. If the tube did not spontaneously spin back and stayed in position upon release, the test was considered negative. Regardless of the results of this test, the tube was secured, and a postprocedure chest radiograph was obtained. The criterion standard for determining a kinked chest tube was its appearance on this chest radiograph. Results: A total of 103 chest tubes were placed by using the Mac‐technique test. The test was positive in eight placements; four tubes were kinked on chest radiograph. The Mac‐technique test was negative in 95 placements; four tubes were kinked on chest radiograph. The Mac technique had a sensitivity of 50% (95% confidence interval [CI] = 15.7% to 84.3%), a specificity of 95.8% (95% CI = 89.6% to 98.8%), a positive likelihood ratio of 11.9, a negative likelihood ratio of 0.52, and an odds ratio using Yates correction of 20.3 (95% CI = 4.1 to 102.1). Conclusions: On the basis of this study, a positive Mac‐technique test is useful to detect chest tubes that are likely to be kinked after insertion and before securing.     

Changes in depression during and following pregnancy

Summary. .Rates of depression were studied in a sample of over 9000 women who were participants in the Avon Longitudinal Study of Pregnancy and Childhood. Assessments of depression were made at 18 and 32 weeks gestation, and at 8 and 32 weeks postpartum. Changes in depressive status across time were modelled using latent Markov modelling methods. This analysis showed that when classification errors were taken into account there was relatively high stability in diagnostic status during pregnancy and after pregnancy. However, the transition from late pregnancy to the early postnatal period showed evidence of increased instability and remission of depression. The net effects of this were that rates of depression tended to decline following childbirth. The implications of these results for a series of issues including measurement errors in depression reports and the prevalence of depression before and after childbirth are discussed.

Attentional Difficulties in Middle Childhood and Psychosocial Outcomes in Young Adulthood

The associations between (dimensionally scored) measures of attentional difficulties at age 8 and psychosocial outcomes at age 18 were examined in a birth cohort of New Zealand children. Increasing attentional difficulties during middle childhood were associated with increased risks of academic failure or difficulties, juvenile offending, and substance use behaviours in young adulthood. However, those with early attentional difficulties were a high-risk group characterised by social disadvantages, early conduct difficulties, lower 1Q, and related characteristics. Statistical adjustments showed: (a) that attentional difficulties were related to later academic success even when due allowance was made for potentially confounding factors; and (b) early attentional difficulties were unrelated to later juvenile offending or substance use behaviours after adjustment for confounding. In all cases there was evidence of consistent dose/response relationships between the extent of early attentional difficulties and later academic outcomes, suggesting that these associations were not confined to those with extreme symptoms.

Evaluation of an educational intervention to increase HIV-testing in high HIV prevalence general practices: a pilot feasibility stepped-wedged randomised controlled trial

Background

HIV-infected patients often present to primary care several times with HIV-indicator conditions before diagnosis but the opportunity to test by healthcare professionals (HCPs) is frequently missed. Current HIV testing rates in primary care are low and educational interventions to facilitate HCPs to increase testing and awareness of HIV are needed.

Method

We implemented a pilot feasibility stepped-wedged randomised controlled trial of an educational intervention in high HIV prevalence practices in Bristol. The training delivered to HCPs including General Practitioners (GP) aimed to increase HIV testing and included why, who, and how to test. The intervention was adapted from the Medical Foundation for HIV and Sexual Health HIV Testing in Practice (MEDFASH) educational tool. Questionnaires assessed HCP feedback and perceived impacts of the intervention. HIV testing rates were compared between control and intervention practices using 12 monthly laboratory totals.

Results

169 HCPs (from 19 practices) received the educational intervention. 127 (75%) questionnaires were completed. Delivery of the intervention was received positively and was perceived as valuable for increasing awareness, confidence and consideration of testing, with HCPs gaining more awareness of HIV testing guidelines. The main pre-training HIV testing barrier reported by GPs was the patient not considering themselves at risk, whilst for nurses it was a concern about embarrassing or offending the patient. Most HCPs reported the intervention addressed these barriers. The HIV testing rate increased more in the control than in the intervention practices: mean difference 2.6 (95% CI 0.5,4.7) compared with 1.9 (??0.5,4.3) per 1000 patients, respectively. The number of HIV tests across all practices increased from 1154 in the first 6?months to 1299 in the second 6?months, an annual increase in testing rate of 2.0 (0.7,3.4) from 16.3 to 18.3 per 1000 patients.

Conclusion

There was a small increase in HIV testing rates over the study period, but this could not be attributed to the educational intervention. More effective and sustainable programmes tailored to each practice context are needed to change testing culture and HCP behaviour. Repeated training, supported by additional measures, such as testing prompts, may be needed to influence primary care HIV testing.

     

An exercise-based cardiac rehabilitation programme for AF patients in the NHS: a feasibility study

There is increasing evidence for the role of exercise-based cardiac rehabilitation in the management of patients with atrial fibrillation (AF). However, this intervention has not yet been widely adopted within the National Health Service (NHS).We performed a feasibility study on the utilisation of an established NHS cardiac rehabilitation programme in the management of AF, and examined the effects of this intervention on exercise capacity, weight, and psychological health. We then identified factors that might prevent patients from enrolling on our programme.Patients with symptomatic AF were invited to participate in an established six-week exercise-based cardiac rehabilitation programme, composed of physical activity and education sessions. At the start of the programme, patients were weighed and measured, performed the six-minute walk test (6MWT), completed the Generalised Anxiety Disorder Questionnaire (GAD-7), and the Patient Health Questionnaire (PHQ-9). Measurements were repeated on completion of the programme.Over two years, 77 patients were invited to join the programme. Twenty-two patients (28.5%) declined participation prior to initial assessment and 22 (28.5%) accepted and attended the initial assessment, but subsequently withdrew from the programme. In total, 33 patients completed the entire programme (63.9 ± 1.7 years, 58% female). On completion, patients covered longer distances during the 6MWT, had lower GAD-7 scores, and lower PHQ-9 scores, compared with their baseline results. Compared with patients that completed the entire programme, those who withdrew from the study had, at baseline, a significantly higher body mass index (BMI), covered a shorter distance during the 6MWT, and had higher PHQ-9 and GAD-7 scores.In conclusion, enrolling patients with AF into an NHS cardiac rehabilitation programme is feasible, with nearly half of those invited completing the programme. In this feasibility study, cardiac rehabilitation resulted in an improved 6MWT, and reduced anxiety and depression levels, in the short term. Severe obesity, higher anxiety and depression levels, and lower initial exercise capacity appear to be barriers to completing exercise-based cardiac rehabilitation. These results warrant further investigation in larger cohorts.Key words: atrial fibrillation, cardiac rehabilitation, National Health Service
