Managing delirium and agitation in elderly hospitalized orthopaedic patients: Part I--Theoretical aspects

Delirium: the lived experience of older people who are delirious post-orthopaedic surgery

Delirium is a common, potentially preventable and reversible cause of postoperative functional disability, morbidity, and mortality. It can lead to increased health-care use and also poses a substantial challenge for nurses caring for patients who experience delirium after surgery. Predominantly, the published work concentrates on diagnosis, reduction of the modifiable risk factors, and treatments. Compared with this body of published work, the experience of delirium from a patient's perspective has been largely ignored except for a limited number of qualitative research reports. The importance of researching the lived experience of delirium is that a better understanding may lead to more empathic, therapeutic nursing care and help other sufferers to know they are not alone. The aims of the study were to explore and clarify the lived experience of delirium. Eleven patients were recruited to the study following discharge post-surgery from an orthopaedic ward of a major tertiary hospital. The study used a qualitative descriptive approach and incorporated grounded theory data analysis processes. The findings of this study provide an insight into the incomprehensible emotional pain suffered by patients while they were delirious and the disparate feelings of remorse, guilt, and shame they experienced after the episode of delirium. Following this study, recommendations for nursing practice include formal follow-up support for patients with post-delirium episodes and more research into the long-term impact of the experience of delirium.

Decreasing patient agitation using individualized therapeutic activities

OVERVIEW

Hospitalized patients who are suffering from cognitive impairment, delirium, suicidal ideation, traumatic brain injury, or another behavior-altering condition are often placed under continuous observation by designated "sitters." These patients may become agitated, which can jeopardize their safety even when a sitter is present. This quality improvement project was based on the hypothesis that agitation can be decreased by engaging these patients in individualized therapeutic activities. The authors created a tool that allowed continuous observers to identify a patient's abilities and interests, and then offer such activities to the patient. Data were collected using a scale that measured patient agitation before, during, and after these activities. The authors found that during the activities, 73% of patients had decreased levels of agitation compared with baseline, and 64% remained less agitated for at least one hour afterward.The intervention appeared effective in reducing levels of agitation in selected patients who were receiving continuous observation on nonpsychiatric units at a large, urban level 1 trauma center. Many patients expressed gratitude for the diversion from their health issues. Further investigation into the effectiveness of this intervention and its impact on the use of medications or restraints is warranted.

Long-acting morphine following hip or knee replacement: a randomized, double-blind, placebo-controlled trial

BACKGROUND

Patients undergoing total hip or knee replacement surgery experience unmanaged pain during postoperative physiotherapy sessions. It was theorized that a baseline opioid would improve pain management.

OBJECTIVES

To examine the effectiveness of adding long-acting oral morphine to a routine postoperative regimen for total hip or knee replacement surgery.

METHODS

The present study was a double-blind, randomized, placebo-controlled trial for patients undergoing total hip or knee replacement surgery. All patients received routine postoperative analgesia; in addition, the treatment group received long-acting oral morphine 30 mg orally twice daily for three days, while the control group received placebo capsules. The primary end point was a decrease in pain scores by two points on a 0- to 10-point pain rating scale. Secondary end points included adverse effects, acute confusion, pain-related interferences in function and sleep, length of stay and patient satisfaction.

RESULTS

Two hundred patients were enrolled in the present study (March 2004 to March 2006). Although the groups were large enough to yield statistical significance, most pain scores did not reach the predetermined improvement for clinical significance. Additionally, there was an increase in opioid usage (P<0.0001), vomiting (P=0.0148) and oversedation (P=0.08). There were no statistically significant changes in function or sleep. Improved satisfaction with pain management was minimal (P=0.052).

DISCUSSION

The present study was undertaken to determine the value of adding a long-acting opioid (morphine) to the usual care of patients undergoing total hip or total knee replacement surgery. The results yielded minimally improved pain scores and additional adverse effects (vomiting and oversedation). Published research in which long-acting opioids (oxycodone) were used for similar postoperative procedures did not robustly report improved pain scores. In addition, patients using a long-acting opioid (oxycodone) during the postoperative period reported somnolence, dizziness and confusion. Statistically, the patients in the present study showed higher confusion scores and no improvement for pain-related interferences with activity or walking. The treatment group did report increased satisfaction; however, the significance was weak.

CONCLUSIONS

Thirty milligrams twice per day of long-acting morphine from days 1 to 3 following total hip and total knee replacement surgery provided minimal improvements in pain scores, and more adverse effects in the treatment group. The overall strength of evidence for improved outcomes is minimal and thus not supported.

Using Nurse Practitioners to Implement Best Practice Care for the Elderly During Hospitalization: The NICHE Journey at the University of Virginia Medical Center

The Nurses Improving Care to Health System (NICHE) program has provided a valuable framework for developing initiatives that address the needs of the elderly. Three NICHE models have been implemented within the University of Virginia Health System since 1992. These include the Geriatric Resource Nurse model, the Acute Care of the Elderly model, and, most recently, the Geriatric Consultation Service model. Nurse practitioners (NPs) with geriatric expertise have provided the leadership in implementing these initiatives to achieve the goal of improving geriatric care delivery within the health system. Each NP functions in a broad role that is tailored to meet the needs of the patients and staff and includes the role components of clinician, educator, team leader, and care coordinator. Sustainability and growth of NICHE is contingent upon demonstrating favorable outcomes that can be directly attributed to NICHE.

Physical and chemical restraints in acute care: Their potential impact on the rehabilitation of older people

Agitation is a major problem for older people and is present in over half of the hospitalizations for people > 65 years of age. In a previous study by the authors, results indicated that nursing actions often did not meet best-practice standards in the care of older, agitated patients. This paper builds on these results by reviewing the literature pertaining to the use of restraints and contributes to the body of knowledge surrounding the impact of the acute-care experience on rehabilitation outcomes. Successful rehabilitation relies on the improvement of functional health outcomes and, for this to happen, physical and emotional well-being are important. The sequelae of restraint use in acute care have the potential to alter peoples' ability to participate fully in a rehabilitation programme, thereby placing their future placement at risk. This paper explores the outcomes of restraint use in the acute-care setting and presents the argument that their effects are likely to be detrimental to rehabilitation outcomes.

Caring for patients with dementia in an acute care environment

Although hospital nurses are skilled in meeting the acute health needs of the elderly, they may not have the expertise required to manage the behavioral disturbances typically seen in this population. Using the Progressively Lowered Stress Threshold Model (PLST), this article helps identify factors that may precipitate undesirable behaviors in the acute care setting and suggests strategies to help nurses prevent or control them.

Cognitive Function and Health-Related Quality of Life After Delirium in Connection With Hip Surgery

NEED

Delirium is a serious psychiatric disorder, and elderly patients who undergo hip surgery are at higher risk for delirium development.

PURPOSE

The purpose was to compare change in cognitive function and health-related quality of life 6 months after hip surgery in patients who experienced postoperative delirium with those who did not.

SAMPLE

A total of 115 patients 75 years or older were included.

MEASURES

Screening for delirium was done using the Diagnostic and Statistical Manual, 4th ed criteria. Cognitive function was measured with the Mini Mental State Examination and health-related quality of life with the SF-36.

RESULTS

Of the 115 patients, 32 became delirious during hospital stay (D group), whereas the remaining patients did not (NonD group). Both D and NonD groups scored lower on the Mini Mental State Examination at follow-up than during hospital stay, but the deterioration was significantly greater in the D group. At follow-up, health-related quality of life was improved in patients who were destined for hip replacement surgery but unchanged or impaired for those with hip fracture. Delirium onset in connection with hip fracture lowered the health-related quality of life even more. At follow-up, low cognitive function correlated with lower scoring in physical function. Greater knowledge about delirious patients' vulnerable positions related to lower cognition and life quality can improve rehabilitation and support for these patients.
