Outcomes following physical restraint reduction programs in two acute care hospitals.

BACKGROUND: Physical restraint rates can be reduced safely in long term care settings, but the strategies used to prevent wandering, falls, and patient aggression have not been tested for their effectiveness in preventing therapy disruption. A restraint reduction program (RRP) consisting of four core components (administrative, educational, consultative, and feedback) was implemented in 1998-1999 in 14 units at two acute care hospitals in geographically distant cities. METHODS: The RRP was targeted at units with prevalence rates of > or = 4% for non-intensive care units (non-ICUs) and > or = 25% for ICUs, as well as two additional units. The RRP was implemented by an interdisciplinary team consisting of geriatricians and nurse specialists. RESULTS: Of the 16,605 admissions to the RRP units, 2,772 cases received RRP consultations. Only six units (four of seven general units and two of six ICUs) demonstrated a relative reduction of > or = 20% in the physical restraint use rate. No increase in secondary outcomes of patient falls and therapy disruptions (patient-initiated discontinuation or dislodgment of therapeutic devices) occurred, injury rates were low, and no deaths occurred as a direct result of either a fall or therapy disruption event. DISCUSSION: Given the minimal success in the ICU settings, further studies are needed to determine effective nonrestraint strategies for critical care patients. ICU clinicians need to be persuaded of the favorable risk-to-benefit ratio of alternatives to physical restraint before they will change their practice patterns. SUMMARY: Efforts to identify more effective interventions that match patient needs and to identify non-clinician factors that affect physical restraint use are needed.

Elderly patients' reports of physical restraint experiences in intensive care units.

BACKGROUND: Use of physical restraints has undesirable sequelae. As they weigh the risks and benefits of protocols for reducing the use of restraints, staff members in intensive care units, where restraints are most used in hospitals, need to know how well elderly patients remember being restrained and how patients perceive the use of restraints. OBJECTIVES: To estimate the proportion of patients who remember being restrained, describe the experience from the patients' perspectives, and describe any distress caused by use of restraints within the overall experience of being in the intensive care unit. METHODS: Transcripts of semistructured, audiotaped interviews of patients who had been in the medical or surgical intensive care unit in any of 3 eastern and midwestern medical centers were analyzed by question and for overall themes. RESULTS: Six patients (40%) remembered some aspect of being restrained but did not report great distress. Patients accepted restraints as needed because of the lack of alternatives. Patients reported remembering that they should not perform certain behaviors but being unable to stop themselves. Patients cited hallucinations and intubation as major stressors in the intensive care unit. Patients' continuing health problems after discharge from the intensive care unit severely limited recruitment of subjects. CONCLUSIONS: Patients do not remember great distress specifically related to the use of restraints, but the overall situation leading to use of restraints is disturbing if remembered. The discovery of methods to reduce the distress of intubation and hallucinations could decrease use of restraints.

Prescribing. Keys to maximizing benefit while avoiding adverse drug effects.

When prescribing for older patients, some physicians are overly cautious, and this strategy can result in a less than optimal treatment outcome. The reluctance to treat aggressively is understandable because the geriatric population is susceptible to adverse drug reactions. The key to maximizing therapy lies in individualizing it as much as possible. There are a number of steps physicians can take to ensure that their patients are not being undertreated. These steps include regular reevaluations of dosages and plasma drug concentrations, recognition and understanding of drug side effects, and avoidance of certain agents. Close monitoring allows physicians to minimize risks, maximize benefits, and get the most out of what modern medications can do to help older patients.

Methodologic issues in conducting research on hospitalized older people.

OBJECTIVE: To describe challenges in conducting research with hospitalized geriatric patients. DESIGN: Quasi-experimental longitudinal study with inperson interviews at baseline and discharge and a three-month postdischarge telephone interview. Study protocol required baseline interviews within 48 hours of admission for patients or 72 hours for proxies. SETTING: 813-bed urban teaching hospital. PARTICIPANTS: 240 patients, mean age 83.8 years, at moderate to high risk for functional decline during hospitalization, admitted from the emergency room to a general medical unit. MEASUREMENTS: Delays starting or interruptions continuing interviews; patient and environmental conditions potentially affecting data quality; and information on proxy use. RESULTS: Timely access to patients or proxies was a major difficulty, resulting in the screening of only 53.1% of 867 potentially eligible patients. Multiple patient contacts and visits were required to complete interviews. Only 61.3% of baseline and 28.1% of follow-up interviews were completed on the initial day of contact. Despite having on-site interviewers 7 days a week, 29% of discharge interviews were conducted by telephone. Interviews were >90% complete in 487 of 503 of encounters (97%). Baseline delays and interruptions were usually due to the presence of medical staff, off-unit tests, patient illness, nurse unavailability for interview, and need for a proxy. Most in-hospital interviews were conducted with others present. Proxies were required for approximately one-third of patients at all three interviews. CONCLUSION: Conducting clinical research with older adults in the current inpatient setting, where patients are more severely ill yet have shorter lengths of stay now than in the past, proves a challenging yet achievable goal. Effective procedures for negotiating the acute care environment are critical to successful studies.

The restraint match-up. Three lessons show how nurse leaders can influence the use of physical restraints.

A study of three hospitals reveals common areas where nurse managers can change the use of physical restraints.

Complementary and alternative medicine in the management of pain, dyspnea, and nausea and vomiting near the end of life. A systematic review.

To review the evidence for efficacy of complementary and alternative medicine (CAM) modalities in treating pain, dyspnea, and nausea and vomiting in patients near the end of life, original articles were evaluated following a search through MEDLINE, CancerLIT, AIDSLINE, PsycLIT, CINAHL, and Social Work Abstracts databases. Search terms included alternative medicine, palliative care, pain, dyspnea, and nausea. Two independent reviewers extracted data, including study design, subjects, sample size, age, response rate, CAM modality, and outcomes. The efficacy of a CAM modality was evaluated in 21 studies of symptomatic adult patients with incurable conditions. Of these, only 12 were directly accessed via literature searching. Eleven were randomized controlled trials, two were non-randomized controlled trials, and eight were case series. Acupuncture, transcutaneous electrical nerve stimulation, supportive group therapy, self-hypnosis, and massage therapy may provide pain relief in cancer pain or in dying patients. Relaxation/imagery can improve oral mucositis pain. Patients with severe chronic obstructive pulmonary disease may benefit from the use of acupuncture, acupressure, and muscle relaxation with breathing retraining to relieve dyspnea. Because of publication bias, trials on CAM modalities may not be found on routine literature searches. Despite the paucity of controlled trials, there are data to support the use of some CAM modalities in terminally ill patients. This review generated evidence-based recommendations and identified areas for future research.

Beyond interviewing skills: twelve steps for training interviewers.

The measurement of many outcomes relies on patients and their families for information that can best be collected through interviews. The authors describe 12 practical suggestions that help ensure achievement of subject enrollment and interview goals.

Drugs and falls in older people: a systematic review and meta-analysis: I. Psychotropic drugs.

OBJECTIVES: To evaluate critically the evidence linking psychotropic drugs with falls in older people. DESIGN: Fixed-effects meta-analysis. DATA SOURCES: English-language articles in MEDLINE (1966 - March 1996) indexed under accidents or accidental falls and aged or age factors; bibliographies of retrieved papers. STUDY SELECTION: Systematic evaluation of sedative/hypnotic, antidepressant, or neuroleptic use with falling in people aged 60 and older. DATA EXTRACTION: Study design, inclusion and exclusion criteria, setting, sample size, response rate, mean age, method of medication verification and fall assessment, fall definition, and the number of fallers and non-fallers taking specific classes of psychotropic drugs. RESULTS: Forty studies, none randomized controlled trials, met eligibility criteria. For one or more falls, the pooled odds ratio (95% confidence interval) was 1.73 (95%CI, 1.52-1.97) for any psychotropic use; 1.50 (95%CI, 1.25-1.79) for neuroleptic use; 1.54 (95%CI, 1.40-1.70) for sedative/hypnotic use; 1.66 (95%CI, 1.4-1.95) for any antidepressant use (mainly TCAs); 1.51 (95%CI, 1.14-2.00) for only TCA use; and 1.48 (95%CI, 1.23-1.77) for benzodiazepine use, with no difference between short and long acting benzodiazepines. For neuroleptics in psychiatric inpatients, the pooled OR was 0.41 (95%CI, 0.21-.82); for all other patients, the pooled OR was 1.66 (95%CI, 1.38-2.00). Comparing > or =1 with > or = 2 falls, mean subject age <75 versus > or =75 years old, communities with <35% versus > or =35% fallers, or subject place of residence did not affect the pooled OR. Increased falls occurred in patients taking more than one psychotropic drug. CONCLUSION: There is a small, but consistent, association between the use of most classes of psychotropic drugs and falls. The evidence to date, however, is based solely on observational data, with minimal adjustment for confounders, dosage, or duration of therapy. The incidence of falls and their consequences in this population necessitate that future large randomized controlled trials of any medication in older persons should measure falls prospectively as an adverse outcome event.

Drugs and falls in older people: a systematic review and meta-analysis: II. Cardiac and analgesic drugs.

OBJECTIVES: To evaluate critically the evidence linking specific classes of cardiac and analgesic drugs to falls in older people. DESIGN: Fixed-effects meta-analysis. DATA SOURCES: English-language articles in MEDLINE (1966 - March 1996) indexed under accidents or accidental falls and aged or age factors; bibliographies of retrieved papers. STUDY SELECTION: Systematic evaluation of cardiac or analgesic drug use and any fall in people aged 60 years and older. DATA EXTRACTION: Study design, inclusion and exclusion criteria, setting, sample size, response rate, mean age, method of medication verification and fall assessment, fall definition, and the number of fallers and nonfallers taking specific classes of cardiac and analgesic drugs. RESULTS: Twenty nine studies met inclusion criteria. None were randomized controlled trials. For one or more falls, the pooled Odds Ratio (95% Confidence Interval) was 1.08 (1.02-1.16) for diuretic use, 1.06 (0.97-1.16) for thiazide diuretics, 0.90 (0.73-1.12) for loop diuretics, 0.93 (0.77-1.11) for beta-blockers, 1.16 (0.87-1.55) for centrally acting antihypertensives, 1.20 (0.92-1.58) for ACE inhibitors, 0.94 (0.77-1.14) for calcium channel blockers, 1.13 (0.95-1.36) for nitrates, 1.59 (1.02-2.48) for type Ia antiarrhythmics, and 1.22 (1.05-1.42) for digoxin use. For analgesic drugs, the pooled OR was 0.97 (0.78-1.20) for narcotic use, 1.09 (0.88-1.34) for nonnarcotic analgesic use, 1.16 (0.97-1.38) for NSAID use, and 1.12 (0.80-1.57) for aspirin use. There was no statistically significant heterogeneity of pooled odds ratios. There were no differences between the pooled odds ratios for studies with mean subject age <75 versus > or =75 years old or for studies in communities with <35% versus > or =35% fallers. In studies of the relationship between psychotropic, cardiac, or analgesic drugs and falls, subjects reporting the use of more than three or four medications of any type were at increased risk of recurrent falls. CONCLUSION: Digoxin, type IA antiarrhythmic, and diuretic use are associated weakly with falls in older adults. No association was found for the other classes of cardiac or analgesic drugs examined. The evidence to date, however, is based solely on observational data, with minimal adjustment for confounders, dosage, or duration of therapy. Older adults taking more than three or four medications were at increased risk of recurrent falls. As a result of the incidence of falls and their consequences in this population, programs designed to decrease medication use should be evaluated for their impact on fall rates.

Help the health care team release its hold on restraint.

As part of a three-site cooperative physical restraint reduction program in acute-care hospitals, a multidisciplinary team created a survey instrument to measure staff's knowledge, unit beliefs about practice patterns, ethical concerns, and more.

Prevalence and patterns of physical restraint use in the acute care setting.

Nurse executives usually have the principal responsibility to respond to the national movement to reduce physical restraint use in hospitals. The results of this three-site, interdisciplinary, prospective incidence study (based on more than 49,000 observations collected on 18 randomly selected days) reveal new patterns in the rationale and types of restraints used. The authors discuss how the results can be used in measuring success and allocating resources for restraint reduction programs.

Avoiding adverse drug effects in elderly patients.

This review delineates why commonly prescribed drugs and dosages often have unexpected responses in the elderly, and suggests ways to improve prescribing for this vulnerable population.

That was the year that was: an evidence-based clinical geriatrics update.

BACKGROUND: Physicians are faced with an ever-growing information base in medical practice. Studies regularly show a disparity between science and patient care, with scientifically validated practices often taking 20 years and more to enter mainstream clinical practice. OBJECTIVES: To review the recent medical literature for high quality studies that practicing geriatricians should be aware of, either because they provide evidence that might lead to a change in clinical practice or because they provide insight into common geriatric syndromes. DESIGN: Overview. DATA SOURCES: All articles abstracted or noted in ACP Journal Club, Evidence-Based Medicine, or The New York Times from July 1996 to June 1997. STUDY SELECTION: Studies that met the standards for inclusion in ACP Journal Club. STUDY DESIGN: Sampling plan (including eligibility criteria), sample size, response rate, data analysis plan, proportion available for follow-up, main outcomes and measures, main results. RESULTS: Review of the 98 articles that met criteria resulted in the identification of several themes of importance to geriatricians, including the hazards of hospitalization, the prevention of NSAID-induced peptic ulcers, and the treatment and prevention of Alzheimer's disease. The results of these studies expand the therapeutic armamentarium of practicing geriatricians, provide new insights into geriatric syndromes, and raise cautions about the use of certain therapies in older adults. CONCLUSIONS: Many methodologically rigorous studies relevant to the medical care of older people have recently been published. Evidence-based medicine and the use of journals of secondary publication are useful tools to enhance the efficiency of journal reading for geriatric practitioners whose interests span the journals of several disciplines and subspecialties.
