Exploring key risks in the medical admissions process

AbstractThis study investigated the hospital admission process in relation to two areas associated with known patient related risks, venous thromboembolism (VTE) risk assessment and medicines reconciliation in an English teaching hospital Acute Medical Unit (AMU). National guidance was available at the time of the study for both of these aspects of care. Government targets with associated financial penalties were set for VTE risk assessment in 2010, there were no similar targets for medicines reconciliation.NHS ethics approval was granted. A novel mixed methodology was used involving direct observations of the patient admissions process, interviews with staff and an audit of case notes. Data were collected over four one-week periods between 2009 and 2011, 36 staff were observed admitting 71 patients, 44 staff were interviewed (25 VTE, 19 medicines reconciliation) and 930 sets of case notes were audited.The observations showed that at the start of the study guidance was rarely followed for both VTE risk assessment and medicines reconciliation. Staff were unaware of its existence and ignorant of the both the associated risks and the level of guideline compliance within the organisation. There were low levels of compliance with local and national VTE guidance until national financial sanctions were introduced when significant increases in the rates of both VTE risk assessment and appropriate prescribing of prophylaxis were seen, however inappropriate prescribing also rose. Observations showed poor medication history taking and prescribing practices, during the study the proportion of items with a prescribing error increased, however the interviews showed that staff did know how to establish an accurate medication history and were aware of the potential problems.A national financial sanction was associated with the effective implementation of VTE guidance however it remains to be seen whether standards can be maintained in a complex high pressure environment. Organisations must also be aware of the potential for unexpected adverse outcomes. Prescribing errors may be reduced if a mechanism can be found to ensure that theoretical knowledge is routinely translated into practice, however greater pharmacy involvement before the admission prescription is written should also be considered

Challenges in implementing government-managed guidance on VTE risk assessment

Background: Implementing venous thromboembolism (VTE) risk assessment guidance on admission to hospital has proved difficult worldwide. In 2010, VTE risk assessment in English hospitals was linked to financial sanctions. This study investigated possible barriers and facilitators for VTE risk assessment in medical patients and evaluated the impact of local and national initiatives. Setting: Acute Medical Unit in one English National Health Service university teaching hospital. Methods: This was a mixed methods study; National Research Ethics Service approval was granted. Data were collected over four 1-week periods; November 2009 (1), January 2010 (2), April 2010 (3) and April 2011 (4). Case notes for all medical patients admitted during these periods were reviewed. Thirty-six staff were observed admitting 71 of these patients; 24 observed staff participated in a structured interview. Results: 876 case notes were reviewed. In total, 82.1% of patients had one or more VTE risk factors and 25.3% one or more bleeding risks. VTE risk assessment rose from a baseline of 6.9–19.6%, following local initiatives, and to 98.7% following financially sanctioned government targets. A similar increase in appropriate prescribing of prophylaxis was seen, but inappropriate prescribing also rose. No staff observed in period 1 conducted VTE risk assessment, risk-assessment forms were largely ignored or discarded during period 2; and electronic recording systems available during period 3 were not accessed. Few patients were asked any VTE-related questions in periods 1, 2 or 3. Interviewees’ actual knowledge of VTE risk was not related to perceived knowledge level. Eight of the 24 staff interviewed were aware of national policies or guidance: none had seen them. Principal barriers identified to risk assessment were: involvement of multiple staff in individual admissions; interruptions; lack of policy awareness; time pressure and complexity of tools. Conclusions: National financial sanctions appear effective in implementing guidance, where other local measures have failed

Modelling the Defensive Potential of Plants

Plants use resources, i.e. coarbon, nutrients, water and enery, either for growth or to defend themselves from biotic and abiotic stresses. This volume provides a timely understanding of resource allocation and its regulation in plants, linking the molecular with biochemical and physiological-level processes. Ecological scenarios covered include competitors, pathogends, hervivores, mycorrhizae, soil micorogranisms, carbon dioxide/ozone regimes, nitrogen and light availabilities. The validity of the "Growth-Differentiation Balance Hypothesis is examined and novel theoretical concepts and approaches to modelling plant resource allocation are discussed. The results presented can be applied in plant breeding and engineering, as well in resource-efficient stand management in agriculture and forestry
