Costs of managing urinary and faecal incontinence in a sub-acute care facility: A "bottom-up" approach

Aims: To measure accurately the direct costs of managing urinary and faecal incontinence in the sub-acute care setting. Materials and Methods: Prospective observational study was undertaken in two sub-acute care units in a metropolitan hospital. A consecutive series of 29 consecutive patients with urinary and/or faecal incontinence, who were in-patients in a geriatric rehabilitation or subacute neurologic unit underwent routine timed voiding protocol, as per usual care. Face-to-face bedside recordings of all incontinence care, with detailed cost analysis, were undertaken. Results: A total of 3,621 occasions of continence care were costed. The median time per 24 hr spent caring for incontinence per patient was 109 min (interquartile range 88-140). Isolated urinary incontinence episodes occurred in 28 patients (96.5%), mixed urinary/faecal incontinence episodes observed in 79.3%, and episodes of pure faecal incontinence were seen in 62%. The median costs of incontinence care in the sub-acute setting was $49AU per 24 hr, the major share ($41) spent on staff wages. The incontinence tasks of toileting assistance, pad changes, bed changes and catheter care were spread evenly across the three 8 hr shifts of duty. Conclusions: As our population demographics include an increasingly greater portion of the elderly, for whom long term institutional care is becoming relatively more scarce, provision of care in the sub-acute unit that may allow rehabilitation and return to home warrants scrutiny. This is the first study that delineates the costs of managing urinary and faecal incontinence in the sub-acute care setting. Such costs are substantial and place a heavy burden upon night-time carets. (C) 2004 Wiley-Liss, Inc.

General practitioner, specialist providers case conferences in palliative care: Lessons learned from 56 case conferences

OBJECTIVE: To describe the utility and acceptability to general practitioners and palliative care staff of case conferences in palliative care. METHOD: Research focussed on case conferences conducted between GPs and staff of three specialist palliative care units (in an inner urban, outer metropolitan and regional setting), at the time of referral of patients to the service. Telephone interviews were conducted with all GPs who participated in a case conference, and focus groups were conducted with palliative care staff. RESULTS: For most GPs, case conferences by teleconference were a time effective and immediate means of information transfer. The best instances for a conference were at time of patient referral, time of discharge to the community, or where the case was complex. General practitioners appreciated access to multiple professionals simultaneously. Workload pressures were a drawback of participation for both GPs and specialists. Palliative care team members thought case conferences gave GPs an appreciation of a team approach, and reduced professional isolation. The usefulness of the case conferences depended on the willingness of the GP to participate. General practitioners would participate again provided they did not have to organise the case conference. Specialist staff were concerned by the financial cost of organising case conferences. DISCUSSION: Case conferences provide useful information exchange between GPs and specialist staff, and are acceptable to both parties. Much depends on the individual GPs attitude toward participation, as well as the timing of the conferences in the course of the patient's illness. Organisation needs to be a task of the specialist units, who would need administrative support to organise them. (author abstract)

Recombinant human activated protein C improves pulmonary function in ovine acute lung injury resulting from smoke inhalation and sepsis

Objective: To investigate the effects of recombinant human activated protein C (rhAPC) on pulmonary function in acute lung injury (ALI) resulting from smoke inhalation in association with a bacterial challenge. Design: Prospective, randomized, controlled, experimental animal study with repeated measurements. Setting: Investigational intensive care unit at a university hospital. Subjects: Eighteen sheep (37.2 +/- 1.0 kg) were operatively prepared and randomly allocated to either the sham, control, or rhAPC group (n = 6 each). After a tracheotomy had been performed, ALI was produced in the control and rhAPC group by insufflation of 4 sets of 12 breaths of cotton smoke. Then, a 30 mL suspension of live Pseudomonas aeruginosa bacteria (containing 2-5 x 10(11) colony forming units) was instilled into the lungs according to an established protocol. The sham group received only the vehicle, i.e., 4 sets of 12 breaths of room air and instillation of 30 mL normal saline. The sheep were studied in the awake state for 24 hrs and were ventilated with 100% oxygen. RhAPC (24 mu g/kg/hr) was intravenously administered. The infusion was initiated 1 hr post-injury and lasted until the end of the experiment. The animals were resuscitated with Ringer's lactate solution to maintain constant pulmonary artery occlusion pressure. Measurements and Main Results., In comparison with nontreatment in controls, the infusion of rhAPC significantly attenuated the fall in PaO2/FiO(2) ratio (control group values were 521 +/- 22 at baseline [BL], 72 +/- 5 at 12 hrs, and 74 +/- 7 at 24 hrs, vs. rhAPC group values of 541 +/- 12 at BL, 151 +/- 29 at 12 hours [p < .05 vs. control], and 118 +/- 20 at 24 hrs), and significantly reduced the increase in pulmonary microvascular shunt fraction (Qs/Qt; control group at BL, 0.14 +/- 0.02, and at 24 hrs, 0.65 +/- 0.08; rhAPC group at BL, 0.24 +/- 0.04, and at 24 hrs, 0.45 +/- 0.02 [p < .05 vs. control]) and the increase in peak airway pressure (mbar; control group at BL, 20 +/- 1, and at 24 hrs, 36 +/- 4; rhAPC group at BL, 21 +/- 1, and at 24 hrs, 28 +/- 2 [p < .05 vs. control]). In addition, rhAPC limited the increase in lung 3-nitrotyrosine (after 24 hrs [%]: sham, 7 +/- 2; control, 17 +/- 1; rhAPC, 12 +/- 1 [p < .05 vs. control]), a reliable indicator of tissue injury. However, rhAPC failed to prevent lung edema formation. RhAPC-treated sheep showed no difference in activated clotting time or platelet count but exhibited less fibrin degradation products (1/6 animals) than did controls (4/6 animals). Conclusions. Recombinant human activated protein C attenuated ALI after smoke inhalation and bacterial challenge in sheep, without bleeding complications.

Exploring the experiences of nurses who care for children who have Acute Life Threatening Events (ALTE) in hospital

This thesis presents a program of work designed to explore and describe what the experience of caring for a child who has an Acute Life Threatening Event (ALTE) is like for the nurses. An ALTE may include a cardiac arrest, respiratory arrest or unplanned admission for a ward to the Paediatric Intensive Care unit. Using the MRC framework for the development of complex interventions, this information was then coupled with theory to develop the PREPARE and SUPPORT interventions. Given the wide-ranging and exploratory nature of this research, a pragmatic, mixed design approach was used to address the aims and objectives of the thesis. The mixed design approach included: a systematic literature review; international survey of practice; interviews with nurses and doctors using Interpretative Phenomenological Analysis; development, refinement and evaluation of interventions during a feasibility study. Two studies were identified through the systematic review which aimed to evaluate the effectiveness of debriefing. The studies did not provide evidence to support the use of these interventions within healthcare. The international survey of practice demonstrated hospitals were using interventions to both prepare and support nurses for these events. The preparatory interventions were clinically focused and the majority of the supportive interventions included a debrief. The interventions were not being evaluated for effectiveness. The interviews conducted with nurses and doctors provided insight into what that experience was like for the participants. Using the MRC framework, this evidence was coupled with theory to develop the PREPARE and SUPPORT interventions. A multidisciplinary working party used an iterative process to refine and evaluate the interventions and study procedures were explored through a feasibility study. The pragmatic, mixed design approach demonstrated how the empirical evidence was coupled with theory and clinical expertise to develop interventions for use within the healthcare environment.

Improving the care of preterm infants: before, during, and after, stabilisation in the delivery room

Introduction Up to 10% of infants require stabilisation during transition to extrauterine life. Enhanced monitoring of cardiorespiratory parameters during this time may improve stabilisation outcomes. In addition, technology may facilitate improved preparation for delivery room stabilisation as well as NICU procedures, through educational techniques. Aim To improve infant care 1) before birth via improved training, 2) during stabilisation via enhanced physiological monitoring and improved practice, and 3) after delivery, in the neonatal intensive care unit (NICU), via improved procedural care. Methods A multifaceted approach was utilised including; a combination of questionnaire based surveys, mannequin-based investigations, prospective observational investigations, and a randomised controlled trial involving preterm infants less than 32 weeks in the delivery room. Forms of technology utilised included; different types of mannequins including a CO2 producing mannequin, qualitative end tidal CO2 (EtCO2) detectors, a bespoke quantitative EtCO2 detector, and annotated videos of infant stabilisation as well as NICU procedures Results Manual ventilation improved with the use of EtCO2 detection, and was positively assessed by trainees. Quantitative EtCO2 detection in the delivery room is feasible, EtCO2 increased over the first 4 minutes of life in preterm infants, and EtCO2 was higher in preterm infants who were intubated. Current methods of heart rate assessment were found to be unreliable. Electrocardiography (ECG) application warrants further evaluation. Perfusion index (PI) monitoring utilised in the delivery room was feasible. Video recording technology was utilised in several ways. This technology has many potential benefits, including debriefing and coaching in procedural healthcare, and warrants further evaluation. Parents would welcome the introduction of webcams in the NICU. Conclusions I have evaluated new methods of improving infant care before, during, and after stabilisation in the DR. Specifically, I have developed novel educational tools to facilitate training, and evaluated EtCO2, PI, and ECG during infant stabilisation. I have identified barriers in using webcams in the NICU, to now be addressed prior to webcam implementation.

Benefits and resource implications of family meetings for hospitalized palliative care patients: research protocol.

BACKGROUND:
Palliative care focuses on supporting patients diagnosed with advanced, incurable disease; it is 'family centered', with the patient and their family (the unit of care) being core to all its endeavours. However, approximately 30-50% of carers experience psychological distress which is typically under recognised and consequently not addressed. Family meetings (FM) are recommended as a means whereby health professionals, together with family carers and patients discuss psychosocial issues and plan care; however there is minimal empirical research to determine the net effect of these meetings and the resources required to implement them systematically. The aims of this study were to evaluate: (1) if family carers of hospitalised patients with advanced disease (referred to a specialist palliative care in-patient setting or palliative care consultancy service) who receive a FM report significantly lower psychological distress (primary outcome), fewer unmet needs, increased quality of life and feel more prepared for the caregiving role; (2) if patients who receive the FM experience appropriate quality of end-of-life care, as demonstrated by fewer hospital admissions, fewer emergency department presentations, fewer intensive care unit hours, less chemotherapy treatment (in last 30 days of life), and higher likelihood of death in the place of their choice and access to supportive care services; (3) the optimal time point to deliver FM and; (4) to determine the cost-benefit and resource implications of implementing FM meetings into routine practice.
METHODS:
Cluster type trial design with two way randomization for aims 1-3 and health economic modeling and qualitative interviews with health for professionals for aim 4.
DISCUSSION:
The research will determine whether FMs have positive practical and psychological impacts on the family, impacts on health service usage, and financial benefits to the health care sector. This study will also provide clear guidance on appropriate timing in the disease/care trajectory to provide a family meeting.

DESCRIBING SLEEP AND SEDATION PRACTICES IN THE ICU: A MULTINATIONAL SURVEY

Introduction Sleep disturbances are common in critically ill patients treated in the intensive care unit (ICU) with the potential for serious consequences and long-term effects on health outcomes and patient morbidity.
Objectives Our aim was to describe sleep management and sedation practices of adult ICUs in ten countries and to evaluate roles and responsibilities of the ICU staff in relation to key sleep and sedation decisions.
Methods A multicenter, self-administered survey sent to nurse managers of adult ICUs across 10 countries. The questionnaire comprised four domains: sleep characteristics of the critically ill; sleep and sedation practices; non-pharmacological and pharmacological interventions used to improve sleep; and the autonomy and influence of nurses on sleeping practices in the ICU.
Results Overall response rate was 66% (range 32% UK to 100% Cyprus), providing data from 522 ICUs. In all countries, the most frequent patient characteristic perceived to identify sleep was lying quietly with closed eyes (N=409, 78%) (range 92% Denmark to 36% Italy). The most commonly used sedation scale was the Richmond Agitation-Sedation Score (RASS) (N=220, 42%) (range 81% UK to 0% Denmark, Cyprus where most ICUs used the Ramsay score). In most ICUs, selection of sleep medication (N=265, 51%) and assessment of effect (N=309, 59%) was performed by physicians and nurses based on collaborative discussion. In a minority of ICUs (N=161, 31%), decisions and assessments were made by physicians alone. The most commonly used (in all countries) non-pharmacological intervention to promote sleep was reducing ICU staff noise (N=473, 91%) (range 100% Denmark, Norway to 78% Canada). Only 95 ICUs (18%) used earplugs on a frequent basis (range 0% Greece, Cyprus, Denmark to 57% Sweden). Propofol was the drug used most commonly for sedation (N=359, 69%) (range 96% Sweden to 29% Canada). Chloral hydrate was used by only 63 (12%) ICUs (range 0% Greece, Cyprus, Denmark, Italy to 56% Germany). Sedation scales were used on a routine basis by 77% of the 522 ICUs. Participants scored nursing autonomy for sleep and sedation management as moderate; median score of 5 (scale of 0 to 10), range 7 (Canada, Greece, Sweden) to 4 (Norway, Poland). Nursing influence on sleep and sedation decisions was perceived considerable; median score 8, range 9 (Denmark) to 5 (Poland).
Conclusions We found considerable across country variation in sleep promotion and sedation management practices though most have adopted a sedation scale as recommended in professional society guidelines. Most ICUs in all countries used a range of pharmacological and non-pharmacological interventions to promote sleep. Most units reported inter-professional decision-making with nurses perceived to have substantial influence on sleep/sedation decisions.

Hipotermia terapêutica pós-parada cardiorrespiratória em hospitais do extremo sul do brasil

A atuação eficaz dos trabalhadores da saúde no atendimento imediato da parada cardiorrespiratória possibilita o efetivo processo de implementação da hipotermia terapêutica, reduzindo possíveis danos cerebrais e proporcionando um melhor prognóstico para o paciente. O presente estudo objetivou conhecer o processo de implementação da hipotermia terapêutica pós-parada cardiorrespiratória em hospitais do extremo sul do Brasil. Tratou-se de uma pesquisa de abordagem qualitativa, do tipo descritiva. O cenário do estudo foram duas Unidades de Terapia Intensiva de dois hospitais onde a hipotermia terapêutica pós-parada cardiorrespiratória é realizada. Os sujeitos do estudo foram médicos, enfermeiros e técnicos de enfermagem atuantes nas referidas unidades. A coleta de dados foi composta por dois momentos. Primeiramente, foi desenvolvida uma pesquisa retrospectiva nos prontuários dos pacientes e, posteriormente, foram aplicadas entrevistas semiestruturadas por meio de roteiro de entrevista com os profissionais citados, as quais foram gravadas com aparelho digital. A coleta de dados ocorreu durante o mês de outubro de 2014. Para interpretação dos dados, foi utilizada a análise textual discursiva, construindo-se três categorias. Na primeira categoria, “processo de implementação da hipotermia terapêutica”, constatou-se que o hospital com uma implementação sistematizada e organizada utiliza um protocolo escrito e, em relação às fases de aplicação da hipotermia terapêutica, ambas as instituições utilizam os métodos tradicionais de indução, manutenção e reaquecimento. A segunda categoria, “facilidades e dificuldades vivenciadas pela equipe de saúde durante a aplicação da hipotermia terapêutica”, identifica a estrutura física, harmonia da equipe, equipamentos para a monitorização constante das condições hemodinâmicas dos pacientes e a otimização do tempo de trabalho como facilitadores. No que tange às dificuldades, constatou-se a aquisição de materiais, como o gelo e o BIS; disponibilidade de um único termômetro esofágico; inexistência de EPI’s; conhecimento insuficiente e inaptidão técnica; ausência de educação permanente e dimensionamento inadequado dos profissionais de enfermagem. Na terceira categoria, “efeitos adversos e complicações encontradas pela equipe de saúde durante a aplicação da hipotermia terapêutica e cuidados de enfermagem realizados”, verificou-se, como efeitos adversos, a ocorrência de tremores, bradicardia e hipotensão e de complicações como hipotermia excessiva e queimaduras de pele. Os cuidados de enfermagem direcionam-se aos cuidados com a pele e extremidades, uso do gelo, sedação, higiene, conforto e preparo de material para monitorização. Concluiu-se que a hipotermia terapêutica é possível de ser aplicada, na realidade das instituições pesquisadas, de maneira segura, eficaz e de baixo custo.

Experiences of health professionals with nutritional support of critically ill patients in tertiary hospitals in Malawi

Background Nutritional support is a recognized determinant of outcome in critically ill patients. Development of critical care services in low-income countries has not been accompanied by certain appropriate ancillary services and interventions, such as adequate nutritional support. This study was designed to investigate the experiences of health professionals who have provided nutritional supportive care to critically ill patients admitted to two major central hospitals in Malawi, with the aim of identifying the common practices in nutritional support in these settings. Materials and Methods A cross-sectional study in which 50 health professionals working in intensive care and high dependency units, admitting both adult and pediatric patients, were interviewed using a semi-structured questionnaire. Data were coded and then analyzed using SPSS version 16.0. Responses between the two hospitals were compared using Fisher’s exact test. Results There was no difference in the composition of respondents from the two hospitals. About 60% of respondents had had experience with nutritional supplementation in their patients—mainly enteral. The most commonly used formulations were the “ready-to-use therapeutic feeds,” followed by modified milk. A high percentage of respondents (40%) reported having used dextrose solution as the sole nutritional supplement. Lack of in-service training, nonexistent nutrition protocols pertaining to acutely and critically ill patients, and a lack of clinical nutritionists were the major challenges identified. Conclusion Knowledge of nutrient supplementation was poor among the respondents. The use of ready-to-use therapeutic feeds was quite common, although there is no evidence of its effectiveness in care of acutely critically ill patients. There is a need to establish nutritional support teams in these tertiary hospitals. Clinical nutritionists would ideally help train and play leadership roles in such teams, who would be responsible for assessing patients for their nutritional needs, and ensuring that the feeds provided to patients are appropriate and adequate for their needs.

Contributos da enfermagem de reabilitação no incremento da autonomia do utente em cuidados intensivos

Este relatório teve como objetivo a análise reflexiva das competências adquiridas e desenvolvidas durante a unidade curricular Relatório/Estágio, inserida no curso de Mestrado em Enfermagem em Gestão de Unidades de Saúde. O estágio foi realizado na Unidade de Cuidados Intensivos (UCI) Dr. Emílio Moreira do Hospital Doutor José Maria Grande, em Portalegre. Um contexto economicamente recessivo implica uma alteração da gestão de unidades de saúde, que, no entanto, não diminua a qualidade dos cuidados prestados. As intervenções de enfermagem de reabilitação realizadas tiveram como objetivo responder às necessidades dos doentes, incrementando a autonomia dos utentes da UCI, apresentando-se um estudo de caso de uma doente com problemas respiratórios. Os ganhos em saúde, avaliados através do grau de funcionalidade, da mobilidade, da qualidade de vida, aumentam significativamente após as intervenções de enfermagem de reabilitação, conforme é demonstrado pela análise dos resultados do estudo de caso, que corroboram a importância das intervenções de enfermagem de reabilitação na redução do tempo de internamento dos utentes. A presença de um enfermeiro especialista em reabilitação é uma mais-valia numa Unidade de Cuidados Intensivos, devido à vasta área a que consegue dar resposta, contribuindo significativamente para uma maior eficácia na gestão de Unidades de Saúde
