What are the critical incidents that affect how people cope with being detained under Section 136 of the Mental Health Act (1983, 2007)?

Abstract

Purpose: Section 136 (S136) of the Mental Health Act (1983, 2007) provides legislative powers for police officers to detain those suspected of being ‘mentally disordered’ for a mental health assessment. Despite its increasing use, there is currently little qualitative research exploring detainee’s experiences.

Methodology: Participants recruited from NHS places of safety participated in a semi-structured interview. The novel application of Critical Incident Technique (CIT) within this study enabled the specific identification of critical incidents which mental health service users thought had either helped with, or worsened the S136 detention experience. A wish list of absent factors was also gathered.

Findings: Six categories of helpful critical incidents, seven categories of unhelpful critical incidents and five categories of wish-list items were identified. The importance of authentic relationships underpinned many categories, as well as challenging stigma, considering previous detentions; and receiving practical support.

Originality/value: The outlined study is the first of its kind to utilise CIT methodology to specifically identify critical incidents related to the process of S136 detention. These findings provide specific ways to improve the experience of detention informed directly by those who have been directly subjected to S136.

• Key points

• Take time to invest in meaningful relationships with those who are detained; asking about the individual’s life experience and their perception of its relationship to their current presenting difficulties.

• Identify the service user’s values -what’s important to them, and what gives meaning to their life – and discuss this in relation to what their worries, concerns or wishes may be for treatment.

• Discuss previous experiences of involuntary admission- this can support all parties involved to consider the impact of detention upon the individual, and services.

• Use problem-free discussions to normalise and help de-stigmatise mental health difficulties and support rapport building.

• Provide practical support, such as food, drink and routinely allow those who are detained to gather personal belongings such as a change of clothes or a book.

• Ensure advocacy services are always available and accessible for those who are detained under S136.

• Where possible, avoid the use of restrictive or stigmatising practices in front of the public where possible (e.g. use of handcuffs, police vehicles as transport) to minimise risk of increasing mental health stigma.

     

Laparoscopy utilization and outcomes for appendicitis in small children

Purpose

To examine the trends in laparoscopic appendectomy (LA) utilization and outcomes for children 5 years or younger.

Methods

We studied 16,028 inpatient admissions for children 5 years of age or less undergoing an appendectomy for acute appendicitis in 2000, 2003, and 2006 using the Kids' Inpatient Database (KID). Laparoscopy frequency, hospital length of stay, and complications were reviewed.

Results

In 2000, 2003 and 2006 appendectomies were done laparoscopically 11.4%, 18.7% and 31.3% of the time, respectively. Children were more likely to undergo LA at a children's hospital (P < 0.001). LA complications were less likely overall (OR: 0.80, CI: 0.70–0.92, P = 0.002) and in perforated cases (OR: 0.78, CI: 0.67-0.91, P = 0.001). LA decreased hospital length of stay by 0.54 days for all patients and 0.70 days for perforated cases (P < 0.001).

Conclusions

Open appendectomy has historically been the standard in children 5 years of age and younger. Laparoscopic appendectomy has slowly gained acceptance for the treatment of appendicitis in smaller children. The use of laparoscopy has increased significantly at all facilities. Furthermore, laparoscopic appendectomy in this age group has a comparatively low complication rate and short hospital length of stay, and is safe in complicated perforated appendicitis cases.     

QT Interval and Long‐Term Mortality Risk in the Framingham Heart Study

Background : The association between QT interval and mortality has been demonstrated in large, prospective population‐based studies, but the strength of the association varies considerably based on the method of heart rate correction. We examined the QT‐mortality relationship in the Framingham Heart Study (FHS). Methods : Participants in the first (original cohort, n = 2,365) and second generation (offspring cohort, n = 4,530) cohorts were included in this study with a mean follow up of 27.5 years. QT interval measurements were obtained manually using a reproducible digital caliper technique. Results : Using Cox proportional hazards regression adjusting for age and sex, a 20 millisecond increase in QTc (using Bazett's correction; QT/RR^1/2 interval) was associated with a modest increase in risk of all‐cause mortality (HR 1.14, 95% CI 1.10–1.18, P < 0.0001), coronary heart disease (CHD) mortality (HR 1.15, 95% CI 1.05–1.26, P = 0.003), and sudden cardiac death (SCD, HR 1.19, 95% CI 1.03–1.37, P = 0.02). However, adjustment for heart rate using RR interval in linear regression attenuated this association. The association of QT interval with all‐cause mortality persisted after adjustment for cardiovascular risk factors, but associations with CHD mortality and SCD were no longer significant. Conclusion : In FHS, there is evidence of a graded relation between QTc and all‐cause mortality, CHD death, and SCD; however, this association is attenuated by adjustment for RR interval. These data confirm that using Bazett's heart rate correction, QTc, overestimates the association with mortality. An association with all‐cause mortality persists despite a more complete adjustment for heart rate and known cardiovascular risk factors.     

The prevalence of Chlamydia trachomatis infection in Australia: a systematic review and meta-analysis

Background

Chlamydia trachomatis is a common sexually transmitted infection in Australia. This report aims to measure the burden of chlamydia infection by systematically reviewing reports on prevalence in Australian populations.

Methods

Electronic databases and conference websites were searched from 1997?C2011 using the terms ??Chlamydia trachomatis?? OR ??chlamydia?? AND ??prevalence?? OR ??epidemiology?? AND ??Australia??. Reference lists were checked and researchers contacted for additional literature. Studies were categorised by setting and participants, and meta-analysis conducted to determine pooled prevalence estimates for each category.

Results

Seventy-six studies met the inclusion criteria for the review. There was a high level of heterogeneity between studies; however, there was a trend towards higher chlamydia prevalence in younger populations, Indigenous Australians, and those attending sexual health centres. In community or general practice settings, pooled prevalence for women <25?years in studies conducted post-2005 was 5.0% (95% CI: 3.1, 6.9; five studies), and for men <30?years over the entire review period was 3.9% (95% CI: 2.7, 5.1; six studies). For young Australians aged <25?years attending sexual health, family planning or youth clinics, estimated prevalence was 6.2% (95% CI: 5.1, 7.4; 10 studies) for women and 10.2% (95% CI: 9.5, 10.9; five studies) for men. Other key findings include pooled prevalence estimates of 22.1% (95% CI: 19.0, 25.3; three studies) for Indigenous women <25?years, 14.6% (95% CI: 11.5, 17.8; three studies) for Indigenous men <25?years, and 5.6% (95% CI: 4.8, 6.3; 11 studies) for rectal infection in men who have sex with men. Several studies failed to report basic demographic details such as sex and age, and were therefore excluded from the analysis.

Conclusions

Chlamydia trachomatis infections are a significant health burden in Australia; however, accurate estimation of chlamydia prevalence in Australian sub-populations is limited by heterogeneity within surveyed populations, and variations in sampling methodologies and data reporting. There is a need for more large, population-based studies and prospective cohort studies to compliment mandatory notification data.     

Single-incision transumbilical levels 1 and 2 axillary lymph node dissection using a flexible endoscope in human cadaveric models

Background

The use of the flexible endoscope as a surgical platform potentially exposes a range of new surgical approaches and benefits yet to be fully defined. A new method using the flexible endoscope to undertake axillary dissection for breast cancer treatment is explored together with an investigation into its acceptability to the general public.

Methods

Endoscopic axillary dissection via a transumbilical approach using the flexible endoscope passed subcutaneously from the umbilicus is described for four human cadaveric axillas. A questionnaire, validated by clinicians, explored the general public’s reaction to the approach and how it might be influenced by potentially serious morbidity such as an increased rate of cancer recurrence.

Results

All axillas were accessed successfully via the transumbilical approach. Levels 1 and 2 axillary dissection was attempted on four axillas. Scarring from previous axillary surgery prevented dissection in one case. In the remaining three cases, respectively 12, 11, and 14 lymph nodes were harvested. The operative times improved with each case, from 1080 to 390 min. A total of 127 people responded to the questionnaire, with 73 % preferring the described approach over the open and periareolar alternatives when morbidities were considered equivalent. When a hypothetical elevated risk of cancer recurrence was included with the transumbilical approach, one-fifth of the public still accepted the approach due to the likelihood of a superior cosmesis.

Conclusion

The use of the flexible endoscope for oncologically safe levels 1 and 2 axillary dissection is possible and would be acceptable to the general public if it were clinically approved. However, significant challenges with the current endoscopic equipment and relevant instrumentation limit the potential of the technique. Technical innovation in terms of new instrument design with improved ergonomics will reduce long operating times and fatigue, thus ensuring surgical acceptance of the flexible endoscope.     

Sense of Coherence and Four-Year Caries Incidence in Finnish Adults

This study assesses whether sense of coherence (SOC) predicts incidence of tooth decay over 4 years and the role of dental behaviours in explaining the effect of SOC on incidence of tooth decay. Data from 994 adults who participated in both the Health 2000 survey and the Follow-Up Study of Finnish Adults' Oral Health were analysed for this study. At baseline, participants provided information on demographic characteristics, education level, the SOC scale and dental behaviours (tooth brushing frequency, dental attendance and sugar intake frequency). The 4-year incidence of tooth decay was calculated using data from baseline and follow-up clinical oral examinations. Baseline SOC was significantly related to 4-year incidence of tooth decay after adjustment for demographic factors and education (relative risk: 0.79, 95% CI: 0.63-0.98). This effect was fully attenuated after further adjustment for the three dental behaviours. Tooth brushing frequency and dental attendance were the only dental behaviours significantly related to incidence of tooth decay. This prospective study suggests that SOC predicts incidence of tooth decay and that dental behaviours may help explaining why adults with strong SOC have lower risk of developing tooth decay than those with weak SOC.     

Influence of Tricuspid Bioprosthetic Mitral Valve Orientation Regarding the Flow Field Inside the Left Ventricle: In Vitro Hydrodynamic Characterization Based on 2D PIV Measurements

The flow patterns of a prosthetic heart valve in the aortic or mitral position can change according to its type and orientation. This work describes the use of 2D particle image velocimetry (PIV) applied to the in vitro flow fields characterization inside the upper part of a left ventricular model at various heart rates and as a function of two orientations of stented tricuspid mitral bioprostheses. In the ventricular model, each mitral bioprosthesis (27 and 31 mm diameter) was installed in two orientations, rotated by 180°, while the aortic bileaflet mechanical valve (27 mm diameter) remained in a fixed orientation. The results (N = 50) showed changes in the intraventricular flow fields according to the mitral bioprostheses positioning. Also, changes in the aortic upstream velocity profiles were noticed as a function of mitral orientations.
