Patient participation in treatment in the context of acute care

This mixed methods, case study identified key patient, clinician and environmental factors associated with hospitalised patients’ ability and willingness to participate in their recovery after cardiac surgery. Patient participation is a significant component of the processes for achieving quality and safety outcomes. The findings inform redesign of the care delivery system to facilitate participation within acute care environments.

Implementation of pressure ulcer prevention best practice recommendations in acute care: an observational study

Pressure ulcers are a common but preventable problem in hospitals. Implementation of best practice guideline recommendations can prevent ulcers from occurring. This 9-year cohort study reports prevalence data from point prevalence surveys during the observation period, and three practice metrics to assess implementation of best practice guideline recommendations: (i) nurse compliance with use of a validated pressure ulcer risk assessment and intervention checklist; (ii) accuracy of risk assessment scoring in usual-care nurses and experienced injury prevention nurses; and (iii) use of pressure ulcer prevention strategies. The prevalence of hospital-acquired pressure ulcers decreased following implementation of an evidence-based prevention programme from 12·6% (2 years preprogramme implementation) to 2·6% (6 years postprogramme implementation) (P < 0·001). Audits between 2003 and 2011 of 4368 patient medical records identified compliance with pressure ulcer prevention documentation according to best practice guidelines was high (>84%). A sample of 270 patients formed the sample for the study of risk assessment scoring accuracy and use of prevention strategies. It was found usual-care nurses under-estimated patients' risk of pressure ulcer development and under-utilised prevention strategies compared with experienced injury prevention nurses. Despite a significant reduction in prevalence of hospital-acquired pressure ulcers and high documentation compliance, use of prevention strategies could further be improved to achieve better patient outcomes. Barriers to the use of prevention strategies by nurses in the acute hospital setting require further examination. This study provides important insights into the knowledge translation of pressure ulcer prevention best practice guideline recommendations at The Northern Hospital.

Children’s experiences of acute hospitalisation to a paediatric emergency and assessment unit – A qualitative study

Short-stay treatment has become a popular form of care as a strategy to cope with increased demands on health care. There is little research that considers children’s experiences of acute hospitalisation to a short-stay care facility such as a Paediatric Emergency and Assessment Unit (PEAU). This study explored the experiences of eight children aged 8–10 years. Semi-structured interviews were carried out to investigate the children’s own experiences of being hospitalised in a PEAU. Thematic content analyses were used. Three major themes were identified: the children’s understanding of disease, treatment and procedures; the children’s experiences of health-care personnel and the PEAU and transformation of everyday life into the settings of the hospital. The children identified the hospital stay as an overall positive experience. The children took part in leisure activities as they would at home and enjoyed time together with their parents while in hospital. In their conversations with staff they adapted to professional terms that they did not necessarily understand. They did not differentiate between professionals. Further work should be considered to clarify the consequences of this. This study has provided some limited insight into the child’s experiences of acute hospitalisation, which should inform nursing care.

Effects of acute alkalosis and acidosis on performance

Ingestion of agents that modify blood buffering action may affect high-intensity performance. Here we present a meta-analysis of the effects of acute ingestion of three such agents - sodium bicarbonate, sodium citrate and ammonium chloride - on performance and related physiological variables (blood bicarbonate, pH and lactate). A literature search yielded 59 useable studies with 188 observations of performance effects. To perform the mixed- model meta-analysis, all performance effects were converted into a percentage change in mean power and were weighted using standard errors derived from exact p-values, confidence limits (CLs) or estimated errors of measurement. The fixed effects in the meta-analytic model included the number of performance-test bouts (linear), test duration (log linear), blinding (yes/no), competitive status (athiete/nonathlete) and sex (male/female). Dose expressed as buffering mmoL/kg/body mass (BM) was included as a strictly proportional linear effect interacted with all effects except blinding. Probabilistic inferences were derived with reference to thresholds for small and moderate effects on performance of 0.5% and 1.5%, respectively. Publication bias was reduced by excluding study estimates with a standard error >2.7%. The remaining 38 studies and 137 estimates for sodium bicarbonate produced a possibly mod- erate performance enhancement of 1.7% (90% CL ± 2.0%) with a typical dose of 3.5mmoL/kg/BM (-0.3g/kgIBM) in a single 1-minute sprint, following blinded consumption by male athletes. In the 16 studies and 45 estimates for sodium citrate, a typical dose of l.SmmoL/kgIBM (-0.5gIkgJBM) had an unclear effect on performance of 0.0% (±1.3%), while the five studies and six estimates for ammonium chloride produced a possibly moderate impairment of 1.6% (±1.9%) with a typical dose of 5.5mmoL/kgIBM (-0.3glkg/BM). Study and subject characteristics had the following modifying small effects on the enhancement of performance with sodium bicarbonate: an increase of 0.5% (±0.6%) with a 1 mmoL/kg/BM increase in dose; an increase of 0.6% (±0.4%) with five extra sprint bouts; a reduction of 0.6% (±0.9%) for each 10-fold increase in test duration (e.g. 1-10 minutes); reductions of 1.1% (± 1 .1%) with nonathletes and 0.7% (±1.4%) with females. Unexplained variation in effects between research settings was typically ± 1.2%. The only noteworthy effects involving physiological variables were a small correlation between performance and pre-exercise increase in blood bicarbonate with sodium bi- carbonate ingestion, and a very large correlation between the increase in blood bicarbonate and time between sodium citrate ingestion and exercise. The approximate equal and opposite effects of sodium bicarbonate and am- monium chloride are consistent with direct performance effects of pH, but sodium citrate appears to have some additional metabolic inhibitory effect. Important future research includes studies of sodium citrate ingestion several hours before exercise and quantification of gastrointestinal symptoms with sodium bicarbonate and citrate. Although individual responses may vary, we recommend ingestion of 0.3-0.5 glkg/BM sodium bicarbonate to improve mean power by 1.7% (±2.0%) in high-intensity races of short duration.

Patient participation in quality pain management during an acute care admission

The objective of the study was to explore patient participation in the context of pain management during a hospital admission for a cardiac surgical intervention of patients with cardiovascular disease. This is a single-institution study, with a case-study design. The unit of analysis was a cardiothoracic ward of a major metropolitan, tertiary referral hospital in Melbourne, Australia. Multiple methods of data collection were used including preadmission and predischarge patient interviews (n=98), naturalistic observations (n=48), and focus group interviews (n=2).

Patient participation in medication safety during an acute care admission

Background : Patient participation in medication management during hospitalization is thought to reduce medication errors and, following discharge, improve adherence and therapeutic use of medications. There is, however, limited understanding of how patients participate in their medication management while hospitalized.Objective : To explore patient participation in the context of medication management during a hospital admission for a cardiac surgical intervention of patients with cardiovascular disease.Design : Single institution, case study design. The unit of analysis was a cardiothoracic ward of a major metropolitan, tertiary referral hospital in Melbourne, Australia. Multiple methods of data collection were used including pre-admission and pre-discharge patient interviews (n = 98), naturalistic observations (n = 48) and focus group interviews (n = 2).Results : All patients had changes made to their pre-operative cardiovascular medications as a consequence of surgery. More patients were able to list and state the purpose and side-effects of their cardiovascular medications at pre-admission than prior to discharge from hospital. There was very little evidence that nurses used opportunities such as medication administration times to engage patients in medication management during hospital admission.Discussion and Conclusions : Failure to engage patients in medication management and provide opportunities for patients to learn about changes to their medications has implications for the quality and safety of care patients receive in hospital and when managing their medications once discharged. To increase the opportunity for patients to participate in medication management, a fundamental shift in the way nurses currently provide care is required.
