Underreporting of needlestick and sharps injuries among healthcare workers in a Swiss University Hospital.

OBJECTIVES: To determine 1) rates of needlestick and sharps injuries (NSSIs) not reported to occupational health services, 2) reasons for underreporting and 3) awareness of reporting procedures in a Swiss university hospital. MATERIALS AND METHODS: We surveyed 6,367 employees having close clinical contact with patients or patient specimens. The questionnaire covered age, sex, occupation, years spent in occupation, history of NSSI during the preceding twelve months, NSSI reporting, barriers to reporting and knowledge of reporting procedures. RESULTS: 2,778 questionnaires were returned (43.6%) of which 2,691 were suitable for analysis. 260/2,691 employees (9.7%) had sustained at least one NSSI during the preceding twelve months. NSSIs were more frequent among nurses (49.2%) and doctors performing invasive procedures (IPs) (36.9%). NSSI rate by occupation was 8.6% for nurses, 19% for doctors and 1.3% for domestic staff. Of the injured respondents, 73.1% reported all events, 12.3% some and 14.6% none. 42.7% of doctors performing invasive procedures (IPs) underreported NSSIs and represented 58.6% of underreported events. Estimation that transmission risk was low (87.1%) and perceived lack of time (34.3%) were the most common reasons for non-reporting. Regarding reporting procedures, 80.1% of respondents knew to contact occupational health services. CONCLUSION: Doctors performing IPs have high rates of NSSI and, through self-assessment that infection transmission risk is low or perceived lack of time, high rates of underreporting. If individual risk analyses underestimate the real risk, such underreporting represents a missed opportunity for post-exposure prophylaxis and identification of hazardous procedures. Doctors' training in NSSI reporting merits re-evaluation.

IPH response to the DSD consultation on regulations to prohibit or restrict irresponsible promotions of alcohol in Northern Ireland

IPH responded to the Department for Social Development consultation on the banning of certain promotions that may encourage irresponsible and excessive drinking. The consultation relates to regulations Article 57A(2)(d) of the 1996 Licensing Order “involving the supply of unlimited amounts of intoxicating liquor for a fixed charge (including any charge for entry to the premises)” and Article 31A(2)(d) of the Registration of Clubs Order “restricting the price at which the holder of a licence or the licence holder’s servant or agent may sell on licensed premises a package containing two or more intoxicating liquor products”. IPH welcomes this consultation and supports the Department’s proposals to restrict promotions that involve the supply of unlimited amounts of intoxicating liquor for a fixed charge. IPH welcomes this tangible action linked to the renewed commitment to tackling alcohol-related harms on the island of Ireland set out in the Steering Group Report on a National Substance Strategy (Dept of Health, 2012) and in the New Strategic Direction on Alcohol and Drugs (DHSSPS, 2011). IPH considers that irresponsible alcohol promotions can contribute to this burden of physical and mental ill-health, accidental and non-accidental injury and other harms associated with excessive alcohol consumption in Northern Ireland. As previously stated in the IPH submissions on the introduction of powers to prohibit or restrict irresponsible alcohol promotions (Dec, 2010), IPH considers that the issues of promotion and price are inter-related. The effectiveness of the proposed restrictions could be reinforced by the expeditious introduction of minimum unit pricing of alcohol on an all-island basis.

IPH Response to Dept of Justice and Equality Review of the Code of Practice on the Sale and Display of Alcohol in Mixed Trading Premises

IPH responded to the Department of Justice, Equality and Defence review of the voluntary Code of Practice for the display and sale of alcohol in supermarkets, convenience stores and similar mixed trading outlets. The voluntary Code was introduced in 2008 as an alternative to the statutory rules for structural separation of alcohol products in mixed trading outlets which are set out in section 9 of the Intoxicating Liquor Act 2008. Interested bodies and individuals were invited to submit comments on the Compliance Report for 2011 and on the effectiveness of the voluntary approach to structural separation by 20th December 2011. The Minister said he intended to also seek the views of the Minister for Health and the Joint Oireachtas Committee on Justice, Defence and Equality before reaching any decision on whether to bring the statutory rules in the 2008 Act into operation.

Extra healthy years or just extra years? What can we know from the data we have on the island of Ireland?

As life expectancy continues to rise, the prevalence of chronic conditions is increasing in our society. However, we do not know if the extra years of life gained are being spent with disability and illness, or in good health. Furthermore, it is unclear if all groups in society experience their extra years of life in the same way. This report examines patterns of health expectancies across the island of Ireland, examining any North-South and socio-economic differences as well looking at differences in data sources. The older population (aged 65 or over) on the island of Ireland is growing and becoming a larger percentage of the total  population. Republic of Ireland Census 2011 revealed that 12% of the RoI population was aged 65 or over (CSO, 2012), and Northern Ireland Census 2011 revealed that 13% of the NI population was aged 65 or over (NISRA, 2012). By 2041 the population aged 65 or over is projected to reach 22% in RoI and 24% in NI (McGill, 2010). It is unclear, however, if this increasing longevity will be enjoyed equally by all strata of society.

Evaluation of two minimally invasive techniques for electroencephalogram recording in wild or freely behaving animals.

Insight into the function of sleep may be gained by studying animals in the ecological context in which sleep evolved. Until recently, technological constraints prevented electroencephalogram (EEG) studies of animals sleeping in the wild. However, the recent development of a small recorder (Neurologger 2) that animals can carry on their head permitted the first recordings of sleep in nature. To facilitate sleep studies in the field and to improve the welfare of experimental animals, herein, we test the feasibility of using minimally invasive surface and subcutaneous electrodes to record the EEG in barn owls. The EEG and behaviour of four adult owls in captivity and of four chicks in a nest box in the field were recorded. We scored a 24-h period for each adult bird for wakefulness, slow-wave sleep (SWS), and rapid-eye movement (REM) sleep using 4 s epochs. Although the quality and stability of the EEG signals recorded via subcutaneous electrodes were higher when compared to surface electrodes, the owls' state was readily identifiable using either electrode type. On average, the four adult owls spent 13.28 h awake, 9.64 h in SWS, and 1.05 h in REM sleep. We demonstrate that minimally invasive methods can be used to measure EEG-defined wakefulness, SWS, and REM sleep in owls and probably other animals.

Skin Cancer Prevention Strategy and Action Plan (PDF 455KB)

Northern Ireland may not enjoy the sunniest climate in the world, or even in the UK, however, in spite of this we have witnessed a significant rise in the incidence of melanoma skin cancer cases in recent years - from 80 cases in 1984 to 282 in 2009 (the latest year for which published figures are available). In relation to non-melanoma skin cancers, there are approximately 2,850 new cases here each year, making it the most common type of cancer diagnosed in Northern Ireland. åÊ The rise in the number of skin cancer cases is alarming. We know that the increase in this particular type of cancer is global and not just confined to our part of the world. We also know there are many factors involved: the significant rise in people travelling on foreign sun holidays; more leisure time being spent out of doors; and damage caused to the ozone layer to name but a few. åÊ Substantial progress in the area of skin cancer awareness raising and prevention has been made through the previous “Melanoma Strategy” which was developed in 1997. However, the unfortunate reality is that we will continue to see rising rates of skin cancer for some time to come as a result of many years of overexposure to the sun before skin cancer prevention programmes were developed. Until we can reverse this trend through effective campaigning and awareness raising, early detection will be key to bringing down mortality rates. While the 1997 strategy was right for its time, there have been many developments since then, necessitating a new strategy to reflect today’s position. åÊ For example, recent studies about the importance of vitamin D have highlighted the need for balance in sun safety messages. This new strategy is not about stopping people from enjoying the sun and its many benefits. Rather, it is about encouraging people to take proportionate measures to prevent overexposure. åÊ åÊ

Salut mental i execució penal

La recerca vol complimentar l’encàrrec de la Secretaria de Serveis Penitenciaris, Rehabilitació i Justícia juvenil, feta al Centre d’Estudis Jurídics i Formació Especialitzada respecte al coneixement de la problemàtica de les persones sotmeses a sancions penals que pateixen algun tipus de trastorn mental. L’interès de la recerca es centra en conèixer l’abast del fenomen de la salut mental en l’execució penal a nivell quantitatiu i conèixer més a fons les característiques i particularitats del col•lectiu afectat, per tal de poder millorar la seva atenció des dels serveis d’execució penal i la seva derivació un cop finalitzat el compliment de la pena o mesura. En la primera part de l’estudi s’aproxima al col•lectiu de persones afectades de trastorns mentals que es troben complint una pena de presó o una mesura de seguretat a Catalunya durant un període determinat de temps. Concretament la mostra la composen els interns penitenciaris de les presons ubicades a les comarques de Barcelona que durant l’any 2005 van passar com a mínim un dia per una unitat de psiquiatria dels centres penitenciaris: CP Homes Barcelona, CP Quatre Camins, CP Brians 1 i la Unitat Hospitalària Penal Penitenciària. També formen part de l’estudi les persones sotmeses a mesures de seguretat de les comarques de Barcelona que estaven d’alta durant l’any 2005. S’analitzen nombroses variables que descriuen aquest col•lectiu i la manera en que s’adapten al compliment de la pena. També es compara aquest grup de persones amb altres col•lectius de penats sense problemes mentals declarats. La segona part de l’estudi recull mitjançant la tècnica Delphi, l’opinió de professionals i experts vinculats al tema de la salut mental i l’execució de penes, a qui s’ha preguntat sobre diverses qüestions clau. Concretament se’ls ha preguntat pel diagnòstic de les persones penades amb trastorns mentals, el seu tractament, les propostes de derivació i les perspectives de futur en aquest tema. S’ha posat especial èmfasi en les previsions i estimacions que fan eles experts sobre les possibilitats futures de la sanitat penitenciària i les propostes de solució i millora dels principals problemes detectats per ells mateixos.

Is PaCO2 management optimal under controlled mechanical ventilation (CMV) during neuro-resuscitation?

INTRODUCTION. Both hypocapnia and hypercapnia can be deleterious to brain injured patients. Strict PaCO2 control is difficult to achieve because of patient's instability and unpredictable effects of ventilator settings changes. OBJECTIVE. The aim of this study was to evaluate our ability to comply with a protocol of controlled mechanical ventilation (CMV) aiming at a PaCO2 between 35 and 40 mmHg in patients requiring neuro-resuscitation. METHODS. Retrospective analysis of consecutive patients (2005-2011) requiring intracranial pressure (ICP) monitoring for traumatic brain injury (TBI), subarachnoid haemorrhage (SAH), intracranial haemorrhage (ICH) or ischemic stroke (IS). Demographic data, GCS, SAPS II, hospital mortality, PaCO2 and ICP values were recorded. During CMV in the first 48 h after admission, we analyzed the time spent within the PaCO2 target in relation to the presence or absence of intracranial hypertension (ICP[20 mmHg, by periods of 30 min) (Table 1). We also compared the fraction of time (determined by linear interpolation) spent with normal, low or high PaCO2 in hospital survivors and non-survivors (Wilcoxon, Bonferroni correction, p\0.05) (Table 2). PaCO2 samples collected during and after apnoea tests were excluded. Results given as median [IQR]. RESULTS. 436 patients were included (TBI: 51.2 %, SAH: 20.6 %, ICH: 23.2 %, IS: 5.0 %), age: 54 [39-64], SAPS II score: 52 [41-62], GCS: 5 [3-8]. 8744 PaCO2 samples were collected during 150611 h of CMV. CONCLUSIONS. Despite a high number of PaCO2 samples collected (in average one sample every 107 min), our results show that patients undergoing CMV for neuro- resuscitation spent less than half of the time within the pre-defined PaCO2 range. During documented intracranial hypertension, hypercapnia was observed in 17.4 % of the time. Since non-survivors spent more time with hypocapnia, further analysis is required to determine whether hypocapnia was detrimental per se, or merely reflects increased severity of brain insult.

Strategic Task Force on Alcohol - Interim Report

The Commission on Liquor Licensing was established by the Minister for Justice, Equality and Law Reform in November 2000 to review the Liquor Licensing system in Ireland. The Commission published an Interim Report with a set of recommendations1, one of which was the establishment of a task force. A High Level Inter-DepartmentalWorking Group considered the report and certain actions were agreed by different Government Departments.The Department of Health and Children agreed to establish a Strategic Task Force on Alcohol. This is their interim report.    

Missed Opportunities: Evolution of Patients Leaving without Being Seen or against Medical Advice during a Six-Year Period in a Swiss Tertiary Hospital Emergency Department.

Aim. The study aimed at describing the evolution over a 6-year period of patients leaving the emergency department (ED) before being seen ("left without being seen" or LWBS) or against medical advice ("left against medical advice" or LAMA) and at describing their characteristics. Methods. A retrospective database analysis of all adult patients who are admitted to the ED, between 2005 and 2010, and who left before being evaluated or against medical advice, in a tertiary university hospital. Results. During the study period, among the 307,716 patients who were registered in the ED, 1,157 LWBS (0.4%) and 1,853 LAMA (0.9%) patients were identified. These proportions remained stable over the period. The patients had an average age of 38.5 ± 15.9 years for LWBS and 41.9 ± 17.4 years for LAMA. The median time spent in the ED before leaving was 102.4 minutes for the LWBS patients and 226 minutes for LAMA patients. The most frequent reason for LAMA was related to the excessive length of stay. Conclusion. The rates of LWBS and LAMA patients were low and remained stable. The patients shared similar characteristics and reasons for leaving were largely related to the length of stay or waiting time.

Chagas disease: current epidemiological trends after the interruption of vectorial and transfusional transmission in the Southern Cone countries

Chagas disease, named after Carlos Chagas who first described it in 1909, exists only on the American Continent. It is caused by a parasite, Trypanosoma cruzi, transmitted to humans by blood-sucking triatomine bugs and by blood transfusion. Chagas disease has two successive phases, acute and chronic. The acute phase lasts 6 to 8 weeks. After several years of starting the chronic phase, 20% to 35% of the infected individuals, depending on the geographical area will develop irreversible lesions of the autonomous nervous system in the heart, esophagus, colon and the peripheral nervous system. Data on the prevalence and distribution of Chagas disease improved in quality during the 1980's as a result of the demographically representative cross-sectional studies carried out in countries where accurate information was not available. A group of experts met in Brasília in 1979 and devised standard protocols to carry out countrywide prevalence studies on human T. cruzi infection and triatomine house infestation. Thanks to a coordinated multi-country program in the Southern Cone countries the transmission of Chagas disease by vectors and by blood transfusion has been interrupted in Uruguay in1997, in Chile in 1999, and in 8 of the 12 endemic states of Brazil in 2000 and so the incidence of new infections by T. cruzi in the whole continent has decreased by 70%. Similar control multi-country initiatives have been launched in the Andean countries and in Central America and rapid progress has been recorded to ensure the interruption of the transmission of Chagas disease by 2005 as requested by a Resolution of the World Health Assembly approved in 1998. The cost-benefit analysis of the investments of the vector control program in Brazil indicate that there are savings of US$17 in medical care and disabilities for each dollar spent on prevention, showing that the program is a health investment with good return. Since the inception in 1979 of the Steering Committee on Chagas Disease of the Special Program for Research and Training in Tropical Diseases of the World Health Organization (TDR), the objective was set to promote and finance research aimed at the development of new methods and tools to control this disease. The well known research institutions in Latin America were the key elements of a world wide network of laboratories that received - on a competitive basis - financial support for projects in line with the priorities established. It is presented the time line of the different milestones that were answering successively and logically the outstanding scientific questions identified by the Scientific Working Group in 1978 and that influenced the development and industrial production of practical solutions for diagnosis of the infection and disease control.

TB Factsheet

What is TB (tuberculosis)? TB is a serious but curable infectious disease. It usually affects the lungs but it can affect other parts of the body. What are the symptoms? Any of the following symptoms may occur: . Cough . Phlegm . High temperature . Sweating at night . Weight loss . Fatigue / general tiredness . Swollen glands If you are concerned that you might have TB, or develop any of these symptoms, please visit your family doctor for advice. How do you catch TB? It is usually spread through the air from someone with the infectious type of TB. The germ gets into the air when that person coughs, sneezes or spits. Who can get TB? Anyone can get TB but it is difficult to catch. It mainly depends on the amount of time that is spent in contact with someone with infectious TB. What if I have been in close contact with someone with infectious TB? If you are identified as a contact at risk from TB then you will be invited for screening. Initial screening consists of a skin test to determine if your immune system recognises TB. The skin test is called the Mantoux test, the result of which needs to be read 48 hours later. People who have a positive skin test and / or evidence of TB infection found on chest X-ray, or who are unwell will be investigated further by a specialist doctor and may be treated with a course of anti-TB medication. How is TB treated? TB is curable. Treatment consists of a long course of different types of specialist antibiotics. What happens next? If you have been identified as a close contact of the case, you will be invited for screening by the accompanying letter. Otherwise, you will have received a general information letter, and have not been identified as requiring screening at this time.

Effects of added dead space on sleep disordered breathing at high altitude

Introduction: Sleep disordered breathing with central apnea or hypopnea frequently occurs during sleep at high altitude. The aim of this study was to assess the effects of added dead space (DS) on sleep disordered breathing and transcutaneous CO2 (PtcCO2) level during sleep at high altitude. Methods: Full night sleep recordings were obtained on 12 unacclimatized mountaineers (11 males, 1 female, mean age 39 ± 12 y.o.) during one of the first 4 nights after arrival in Leh, Ladakh (3500 m). In random order, half of the night was spent with a 500 ml increase in dead space through a custom designed full face mask and the other half without it. PtcCO2 was measured in 3 participants. Results: Baseline recordings reveled two clearly distinct groups: one with severe sleep disordered breathing (n = 5) and the other with mild or no disordered breathing (n = 7). Added dead space markedly improved breathing in the first group (baseline vs DS): apnea hypopnea index (AHI) 70.3 ± 25.8 vs 29.4 ± 6.9 (p = 0.013), oxygen desaturation index (ODI): 72.9 ± 24.1/h vs 42.5 ± 14.4 (p = 0.031), whereas it had no significant effect in the second group. Added dead space did not have a significant effect on mean oxygen saturation level. Respiratory events were almost exclusively central apnea or hypopnea except for one subject. Only a minor increase in mean PtcCO2 (n = 3) was observed: 33.6 ± 1.8 mm Hg at baseline and 35.0 ± 2.62 mm Hg with DS. Sleep quality was preserved under dead space condition, since the microarousal rate remained unchanged (16.8 ± 8.7/h vs 19.4 ± 18.6/h (p = 0.51). Conclusion: In mountaineers with severe sleep disordered breathing at high altitude, a 500 ml increase in dead space through a fitted mask significantly improves nocturnal breathing.

Impact of reduced cerebral perfusion pressure on outcome after severe traumatic brain injury is dependent on brain tissue oxygen pressure

INTRODUCTION. Reduced cerebral perfusion pressure (CPP) may worsen secondary damage and outcome after severe traumatic brain injury (TBI), however the optimal management of CPP is still debated. STUDY HYPOTHESIS: We hypothesized that the impact of CPP on outcome is related to brain tissue oxygen tension (PbtO2) level and that reduced CPP may worsen TBI prognosis when it is associated with brain hypoxia. DESIGN. Retrospective analysis of prospective database. METHODS. We analyzed 103 patients with severe TBI who underwent continuous PbtO2 and CPP monitoring for an average of 5 days. For each patient, duration of reduced CPP (\60 mm Hg) and brain hypoxia (PbtO2\15 mm Hg for[30 min [1]) was calculated with linear interpolation method and the relationship between CPP and PbtO2 was analyzed with Pearson's linear correlation coefficient. Outcome at 30 days was assessed with the Glasgow Outcome Score (GOS), dichotomized as good (GOS 4-5) versus poor (GOS 1-3). Multivariable associations with outcome were analyzed with stepwise forward logistic regression. RESULTS. Reduced CPP (n=790 episodes; mean duration 10.2 ± 12.3 h) was observed in 75 (74%) patients and was frequently associated with brain hypoxia (46/75; 61%). Episodes where reduced CPP were associated with normal brain oxygen did not differ significantly between patients with poor versus those with good outcome (8.2 ± 8.3 vs. 6.5 ± 9.7 h; P=0.35). In contrast, time where reduced CPP occurred simultaneously with brain hypoxia was longer in patients with poor than in those with good outcome (3.3±7.4 vs. 0.8±2.3 h; P=0.02). Outcome was significantly worse in patients who had both reduced CPP and brain hypoxia (61% had GOS 1-3 vs. 17% in those with reduced CPP but no brain hypoxia; P\0.01). Patients in whom a positive CPP-PbtO2 correlation (r[0.3) was found also were more likely to have poor outcome (69 vs. 31% in patients with no CPP-PbtO2 correlation; P\0.01). Brain hypoxia was an independent risk factor of poor prognosis (odds ratio for favorable outcome of 0.89 [95% CI 0.79-1.00] per hour spent with a PbtO2\15 mm Hg; P=0.05, adjusted for CPP, age, GCS, Marshall CT and APACHE II). CONCLUSIONS. Low CPP may significantly worsen outcome after severe TBI when it is associated with brain tissue hypoxia. PbtO2-targeted management of CPP may optimize TBI therapy and improve outcome of head-injured patients.
