Understanding the determinants of Australian hospital nurses' hand hygiene decisions following the implementation of a national hand hygiene initiative

Hand hygiene is the primary measure in hospitals to reduce the spread of infections, with nurses experiencing the greatest frequency of patient contact. The ‘5 critical moments’ of hand hygiene initiative has been implemented in hospitals across Australia, accompanied by awareness-raising, staff training and auditing. The aim of this study was to understand the determinants of nurses’ hand hygiene decisions, using an extension of a common health decision-making model, the theory of planned behaviour (TPB), to inform future health education strategies to increase compliance. Nurses from 50 Australian hospitals (n = 2378) completed standard TPB measures (attitude, subjective norm, perceived behavioural control [PBC], intention) and the extended variables of group norm, risk perceptions (susceptibility, severity) and knowledge (subjective, objective) at Time 1, while a sub-sample (n = 797) reported their hand hygiene behaviour 2 weeks later. Regression analyses identified subjective norm, PBC, group norm, subjective knowledge and risk susceptibility as the significant predictors of nurses’ hand hygiene intentions, with intention and PBC predicting their compliance behaviour. Rather than targeting attitudes which are already very favourable among nurses, health education strategies should focus on normative influences and perceptions of control and risk in efforts to encourage hand hygiene adherence.

Development and evaluation of training in culturally specific screening and brief intervention for hospital patients with alcohol-related injuries

Objective To evaluate health practitioners’ confidence and knowledge of alcohol screening, brief intervention and referral after training in a culturally adapted intervention on alcohol misuse and well-being issues for trauma patients. Design Mixed methods, involving semi-structured interviews at baseline and a post-workshop questionnaire. Setting: Targeted acute care within a remote area major tertiary referral hospital. Participants Ten key informants and 69 questionnaire respondents from relevant community services and hospital-based health care professionals. Intervention Screening and brief intervention training workshops and resources for 59 hospital staff. Main outcome measures Self-reported staff knowledge of alcohol screening, brief intervention and referral, and satisfaction with workshop content and format. Results After training, 44% of participants reported being motivated to implement alcohol screening and intervention. Satisfaction with training was high, and most participants reported that their knowledge of screening and brief intervention was improved. Conclusion Targeted educational interventions can improve the knowledge and confidence of inpatient staff who manage patients at high risk of alcohol use disorder. Further research is needed to determine the duration of the effect and influence on practice behaviour. Ongoing integrated training, linked with systemic support and established quality improvement processes, is required to facilitate sustained change and widespread dissemination.

Influence of starvation and clofibrate administration on oxidative phosphorylation by rat liver mitochondria

Whole cells, homogenates and mitochondrial obtained from the livers of albino rats which were starved for 6 days or more showed a 50% decrease in oxidative activity. The decrease could be corrected by the addition of cytochrome c in vitro. The phosphorylative activity of mitochondria remained unaffected. The decrease in oxidative rate was not observed when starving animals were given the anti-hypercholesterolaemic drug clofibrate. The total cellular concentration of cytochrome c was not affected by starvation. However, the concentration of the pigment in hepatic mitochondria isolated from starving animals was less than half that in normal mitochondria. Clofibrate-treated animals did not show a decreased concentration of cytochrome c in hepatic mitochondria. Mitochondria isolated from starving animals, though deficient in cytochrome c, did not show any decrease in succinate dehydrogenase activity or in the rate of substrate-dependent reduction of potassium ferricyanide or attendant phosphorylation. In coupled mitochondria, ferricyanide may not accept electrons from the cytochrome c in the respiratory chain. Starvation decreases the concentration of high-affinity binding sites for cytochrome c on the mitochondrial membrane. The dissociation constant increases in magnitude.

Integrated lean six sigma approach for patient flow improvement in hospital emergency department

This research aims to develop an Integrated Lean Six Sigma approach to investigate and resolve the patient flow problems in hospital emergency departments. It was proposed that the voice of the customer and the voice of the process should be considered simultaneously to investigate the current process of patient flow. Statistical analysis, visual process mapping with A3 problem solving sheet, and cause and effect diagrams have been used to identify the major patient flow issues. This research found that engaged frontline workers, long-term leadership obligation, an understanding of patients' requirements and the implementation of a systematic integration of lean strategies could continuously improve patient flow, health care service and growth in the emergency departments.

The Pharmacology of Oxycodone : Studies In Vitro, In Vivo and In Humans

The antinociceptive properties of oxycodone and its metabolites were studied in models of thermal and mechanical nociception and in the spinal nerve ligation (SNL) model of neuropathic pain in rats. Oxycodone induced potent antinociception after subcutaneous (s.c.) administration in all models of nociception used in rats compared with morphine, methadone and its enantiomers. In the SNL model of neuropathic pain in rats, oxycodone produced dose dependent antinociception after s.c. administration. The antinociceptive effects of s.c. oxycodone were antagonized by naloxone but not by nor-binaltorphimine (Nor-BNI) a selective κ-opioid receptor antagonist indicating that the antinociceptive properties of oxycodone are predominantly μ-opioid receptor-mediated. The antinociceptive activity of oxymorphone, noroxycodone, and noroxymorphone, oxidative metabolites of oxycodone, were studied to determine their role in the oxycodone-induced antinociception in the rat. Of the metabolites of oxycodone s.c. administration of oxymorphone produced potent thermal and mechanical antinociception. Noroxycodone had a poor antinociceptive effect and noroxymorphone was inactive. Oxycodone produced naloxone-reversible antinociception after intrathecal (i.t) administration with a poor potency compared with morphine and oxymorphone. This seems to be related to the low efficacy and potency of oxycodone to stimulate μ-opioid receptor activation in the spinal cord in μ-opioid receptor agonist-stimulated (GTP)γ[S] autoradiography, compared with morphine and oxymorphone. All metabolites studied were more potent than oxycodone after i.t. administration. I.t. noroxymorphone induced a significantly longer lasting antinociceptive effect compared with the other drugs studied. The role of cytochrome P450 (CYP) 2D6-mediated metabolites on the analgesic activity of oxycodone in humans was studied by blocking the CYP2D6-mediated metabolism of oxycodone with paroxetine. Paroxetine co-administration had no effect on the analgesic effect of oxycodone compared with placebo in chronic pain patients, indicating that oxycodone-induced analgesia and adverse-effects are not dependent of the CYP2D6-mediated metabolism in humans. Although oxycodone has many pharmacologically active metabolites, they seem to have an insignificant role in oxycodone-induced antinociception in humans and rats.

Routine Measurement of Health-Related Quality of Life in Assessing Cost-Effectiveness in Secondary Health Care

Aims: The aims of this study were 1) to identify and describe health economic studies that have used quality-adjusted life years (QALYs) based on actual measurements of patients' health-related quality of life (HRQoL); 2) to test the feasibility of routine collection of health-related quality of life (HRQoL) data as an indicator of effectiveness of secondary health care; and 3) to establish and compare the cost-utility of three large-volume surgical procedures in a real-world setting in the Helsinki University Central Hospital, a large referral hospital providing secondary and tertiary health-care services for a population of approximately 1.4 million. Patients and methods: So as to identify studies that have used QALYs as an outcome measure, a systematic search of the literature was performed using the Medline, Embase, CINAHL, SCI and Cochrane Library electronic databases. Initial screening of the identified articles involved two reviewers independently reading the abstracts; the full-text articles were also evaluated independently by two reviewers, with a third reviewer used in cases where the two reviewers could not agree a consensus on which articles should be included. The feasibility of routinely evaluating the cost-effectiveness of secondary health care was tested by setting up a system for collecting HRQoL data on approximately 4 900 patients' HRQoL before and after operative treatments performed in the hospital. The HRQoL data used as an indicator of treatment effectiveness was combined with diagnostic and financial indicators routinely collected in the hospital. To compare the cost-effectiveness of three surgical interventions, 712 patients admitted for routine operative treatment completed the 15D HRQoL questionnaire before and also 3-12 months after the operation. QALYs were calculated using the obtained utility data and expected remaining life years of the patients. Direct hospital costs were obtained from the clinical patient administration database of the hospital and a cost-utility analysis was performed from the perspective of the provider of secondary health care services. Main results: The systematic review (Study I) showed that although QALYs gained are considered an important measure of the effectiveness of health care, the number of studies in which QALYs are based on actual measurements of patients' HRQoL is still fairly limited. Of the reviewed full-text articles, only 70 reported QALYs based on actual before after measurements using a valid HRQoL instrument. Collection of simple cost-effectiveness data in secondary health care is feasible and could easily be expanded and performed on a routine basis (Study II). It allows meaningful comparisons between various treatments and provides a means for allocating limited health care resources. The cost per QALY gained was 2 770 for cervical operations and 1 740 for lumbar operations. In cases where surgery was delayed the cost per QALY was doubled (Study III). The cost per QALY ranges between subgroups in cataract surgery (Study IV). The cost per QALY gained was 5 130 for patients having both eyes operated on and 8 210 for patients with only one eye operated on during the 6-month follow-up. In patients whose first eye had been operated on previous to the study period, the mean HRQoL deteriorated after surgery, thus precluding the establishment of the cost per QALY. In arthroplasty patients (Study V) the mean cost per QALY gained in a one-year period was 6 710 for primary hip replacement, 52 270 for revision hip replacement, and 14 000 for primary knee replacement. Conclusions: Although the importance of cost-utility analyses has during recent years been stressed, there are only a limited number of studies in which the evaluation is based on patients own assessment of the treatment effectiveness. Most of the cost-effectiveness and cost-utility analyses are based on modeling that employs expert opinion regarding the outcome of treatment, not on patient-derived assessments. Routine collection of effectiveness information from patients entering treatment in secondary health care turned out to be easy enough and did not, for instance, require additional personnel on the wards in which the study was executed. The mean patient response rate was more than 70 %, suggesting that patients were happy to participate and appreciated the fact that the hospital showed an interest in their well-being even after the actual treatment episode had ended. Spinal surgery leads to a statistically significant and clinically important improvement in HRQoL. The cost per QALY gained was reasonable, at less than half of that observed for instance for hip replacement surgery. However, prolonged waiting for an operation approximately doubled the cost per QALY gained from the surgical intervention. The mean utility gain following routine cataract surgery in a real world setting was relatively small and confined mostly to patients who had had both eyes operated on. The cost of cataract surgery per QALY gained was higher than previously reported and was associated with considerable degree of uncertainty. Hip and knee replacement both improve HRQoL. The cost per QALY gained from knee replacement is two-fold compared to hip replacement. Cost-utility results from the three studied specialties showed that there is great variation in the cost-utility of surgical interventions performed in a real-world setting even when only common, widely accepted interventions are considered. However, the cost per QALY of all the studied interventions, except for revision hip arthroplasty, was well below 50 000, this figure being sometimes cited in the literature as a threshold level for the cost-effectiveness of an intervention. Based on the present study it may be concluded that routine evaluation of the cost-utility of secondary health care is feasible and produces information essential for a rational and balanced allocation of scarce health care resources.

This study concerns the implementation of steering by contracting in health care units and in the work of the doctors employed by them. The study analyses how contracting as a process is being implemented in hospital district units, health centres and in the work of their doctors, as well as how these units carry out their operations and patient care within the restrictions set by the contracts. Based on interviews with doctors, the study analyses the realisation of operations within the units from the doctors perspective and through their work. The key result of the study is that the steering impact of contracting was not felt at the level of practical work. The contracting was implemented by assigning the related tasks to management only. The management implemented the contract by managing their resources rather than by intervening in doctors activities or the content of their tasks. The steering did not extend to improving practical care processes. This allowed the unchanged continuation of core operations in an autonomous manner and in part, protected from the impacts of contracting. In health centres, the contract concluded was viewed as merely steering the operations of the hospital district and its implementation did not receive the support of the centres. The fact that primary health care and specialised health care constitute separate contracting parties had adverse effects on the contract s implementation and the integration of care. A theoretical review unveiled several reasons for the failure of steering by contracting to alter operations within units. These included the perception steering by contracting as a weak change incentive. The doctors shunned the introduction of an economic logic and ideology into health care and viewed steering by contracting as a hindrance to delivering care to patients and a disturbance to their work and patient relationships. Contracting caused tensions between representatives of the financial administration and health care professionals. It also caused internal tensions, while it had varying impacts on different specialities, including the introduction of varying potential to influence contracts. Most factors preventing the realisation of the steering objective could have been ameliorated through positive leadership. There is a need to bridge the gap between financial steering and patient work. Key measures include encouraging the commitment of middle management, supporting leadership expertise and identifying the right methods of contributing to a mutual understanding between the cultures of financing, administration and health care. Criticism of the purchasers expertise and the view that undersized orders are due to the purchaser s financial difficulties underlines the importance of the purchaser s size. Overly detailed, product-based contracts seemed to place the focus on the quantities and costs of services rather than health impacts and efficiency of operations. Bundling contracts into larger service packages would encourage the enhancement of operations. Steering by contracting represents unexploited potential: it could function as a forum for integrated regional planning of services, and the prioritisation and integration of care, and offer an opportunity and an incentive for developing core operations.

Effect of waiting time on health outcomes and service utilization : A prospective randomized study on patients admitted to hospital for hip or knee replacement

Although the principle of equal access to medically justified treatment has been promoted by official health policies in many Western health care systems, practices do not completely meet policy targets. Waiting times for elective surgery vary between patient groups and regions, and growing problems in the availability of services threaten equal access to treatment. Waiting times have come to the attention of decision-makers, and several policy initiatives have been introduced to ensure the availability of care within a reasonable time. In Finland, for example, the treatment guarantee came into force in 2005. However, no consensus exists on optimal waiting time for different patient groups. The purpose of this multi-centre randomized controlled trial was to analyse health-related quality of life, pain and physical function in total hip or knee replacement patients during the waiting time and to evaluate whether the waiting time is associated with patients health outcomes at admission. This study also assessed whether the length of waiting time is associated with social and health services utilization in patients awaiting total hip or knee replacement. In addition, patients health-related quality of life was compared with that of the general population. Consecutive patients with a need for a primary total hip or knee replacement due to osteoarthritis were placed on the waiting list between August 2002 and November 2003. Patients were randomly assigned to a short waiting time (maximum 3 months) or a non-fixed waiting time (waiting time not fixed in advance, instead the patient followed the hospitals routine practice). Patients health-related quality of life was measured upon being placed on the waiting list and again at hospital admission using the generic 15D instrument. Pain and physical function were evaluated using the self-report Harris Hip Score for hip patients and a scale modified from the Knee Society Clinical Rating System for knee patients. Utilization measures were the use of home health care, rehabilitation and social services, physician visits and inpatient care. Health and social services use was low in both waiting time groups. The most common services used while waiting were rehabilitation services and informal care, including unpaid care provided by relatives, neighbours and volunteers. Although patients suffered from clear restrictions in usual activities and physical functioning, they seemed primarily to lean on informal care and personal networks instead of professional care. While longer waiting time did not result in poorer health-related quality of life at admission and use of services during the waiting time was similar to that at the time of placement on the list, there is likely to be higher costs of waiting by people who wait longer simply because they are using services for a longer period. In economic terms, this would represent a negative impact of waiting. Only a few reports have been published of the health-related quality of life of patients awaiting total hip or knee replacement. These findings demonstrate that, in addition to physical dimensions of health, patients suffered from restrictions in psychological well-being such as depression, distress and reduced vitality. This raises the question of how to support patients who suffer from psychological distress during the waiting time and how to develop strategies to improve patients initiatives to reduce symptoms and the burden of waiting. Key words: waiting time, total hip replacement, total knee replacement, health-related quality of life, randomized controlled trial, outcome assessment, social service, utilization of health services

Inpatient hospital care and its costs among type 1 diabetic patients in Finland : a nationwide longitudinal study

Background. In Finland, the incidence of type 1 diabetes mellitus (T1DM) is the highest in the world, and it continues to increase steadily. No effective preventative interventions exist either for individuals at high risk or for the population as a whole. In addition to problems with daily lifelong insulin replacement therapy, T1DM patients with long-lasting disease suffer from various diabetes related complications. The complications can lead to severe impairments and reductions in functional capacity and quality of life and in the worst case they can be fatal. Longitudinal studies on the costs of T1DM are extremely rare, especially in Finland. Typically, in these studies, distinctions between the various types of diabetes have not been made, and costs have not been calculated separately for the sexes. Aims. The aim of this study was to describe inpatient hospital care and costs of inpatient care in a cohort of 5,166 T1DM patients by sex during 1973-1998 in Finland. Inpatient care and costs of care due to T1DM without complications, due to T1DM with complications and due to other causes were calculated separately. Material and Methods. The study population consisted of all Finnish T1DM patients diagnosed before the age of 18 years between January 1st in 1965 and December 31st in 1979 and derived from the Finnish population based T1DM register (N=5,120 in 1979 and N=4,701 in 1997). Data on hospitalisations were obtained from the Finnish Hospital Discharge Register. Results. In the early stages of T1DM, the majority of the use of inpatient care was due to the treatment of T1DM without complications. There were enormous increases in the use of inpatient care for certain complications when T1DM lasted longer (from 9.5 years to 16.5 years). For women, the yearly number of bed-days for renal complications increased 4.8-fold, for peripheral vascular disease 4.3-fold and for ophthalmic complications 2.5-fold. For men, the corresponding increases were as follows: 5-fold, 6.9-fold and 2.5-fold. The yearly bed-days for glaucoma increased 8-fold, nephropathy 7-fold and microangiopathy 6-fold in the total population. During these 7 years, the yearly numbers of bed-days for T1DM without complications dropped dramatically. The length of stay in inpatient care decreased notably, but hospital visits became more frequent when the length of duration of T1DM increased from 9.5 years to 16.5 years. The costs of treatments due to complications increased when T1DM lasted longer. Costs due to inpatient care of complications in the cohort 2.5-folded as duration of T1DM increased from 9.5 years to 16.5 years, while the total costs of inpatient care in the cohort dropped by 22% due to an 80% decrease in the costs of care of T1DM without complications. Treating complications of female patients was more expensive than treating complications of men when T1DM had lasted 9.5 years; the mean annual costs for inpatient care of a female diabetic (any cause) were 1,642 , and the yearly costs of care of complications were 237 . The corresponding yearly mean costs for a male patient were 1,198 and 167 . Treating complications of female patients was more expensive than that of male patients also when the duration of diabetes was 16.5 years, although the difference in average annual costs between sexes was somewhat smaller. Conclusions. In the early phases of T1DM, the treatment of T1DM without complications causes a considerable amount of hospital bed-days. The use of inpatient care due to complications of T1DM strongly increases with ageing of patients. The economic burden of inpatient care of T1DM is substantial.
