The incidence of attempted CPR in nursing homes

Resuscitation decisions in Irish long-stay units

BACKGROUND

Little is known of how cardiopulmonary resuscitation (CPR) decisions are made in Irish long-term care settings.

AIM

To examine how CPR decisions are made in Irish long-stay units and those factors associated with use or non-use of CPR.

METHODS

We surveyed each public long-stay unit and a random sample of private nursing homes across the country.

RESULTS

Of the 84 long-stay units that responded (response rate 58%), basic CPR had been performed in 32% and advanced CPR (including defibrillation) in 10%. Only 13% of the units had a written CPR policy. Units performing CPR (N = 35) were closer to an acute hospital, more likely to have short-term residents and more likely to have a CPR policy (all P < 0.05). There were no significant differences between public and private units.

CONCLUSION

The widely disparate approaches to CPR in different Irish long-stay units suggest the need for national guidelines on this issue.

The interface between residential aged care and the emergency department: a systematic review

BACKGROUND

emergency care for older people living in residential aged care facilities (RACF) is a complex area of health policy. The epidemiology of patient transfer between RACF and hospital emergency departments (ED), clinical outcomes and costs associated with transfer and efficacy of programs aiming to reduce transfer are not well known.

DESIGN

systematic review based on a comprehensive literature search in three electronic databases and published article reference lists.

RESULTS

the incidence of transfer from RACF to ED is >30 transfers/100 RACF beds/year in most studies. The casemix from RACF is varied and reflects that of the broad elderly population, with some risk difference. At least 40% of transfers are not admitted to hospital. There is insufficient data to fully address our other questions; however, hospitalisations from RACF can be reduced through advanced care planning, use of management guidelines for acute illnesses and improved primary care.

CONCLUSIONS

residents of RACF have a high annual risk of transfer to ED. The clinical benefit and cost effectiveness of ED care, and alternate programs to reduce ED transfer, cannot be confidently compared from published work. Further research is required to accurately describe these and to determine their comparative worth.

Cardiopulmonary resuscitation in older people – a review

Survival to discharge after in-hospital cardiopulmonary resuscitation (CPR) is about 20% in those aged 65–69 years, declining with advancing age to about 10% in those aged 90 years or more. There are conflicting reports on whether or not advanced age, independent of the severity of acute and chronic illness, is a determinant of outcome. Recognition that the outcome of CPR in hospital patients is often poor has prompted extensive debate regarding the appropriate use of this procedure. In particular, there has been concern about unnecessary CPR in extended-care and hospice settings. Conversely, there has also been evidence that doctors and families may be prone to underestimate the quality of life and likelihood of benefit from CPR in older people and to make resuscitation decisions without considering the preferences of older people themselves. Recent guidelines have attempted to strike a balance between ensuring patient participation whenever possible but without offering illusory choices where CPR is very unlikely to succeed.

Outcomes of cardiac arrest in the nursing home: destiny or futility? [see comment]

OBJECTIVE

To compare EMS system characteristics and outcomes between nursing home (NH) patients and out-of-hospital cardiac arrest (OHCA) patients whose arrests occurred in a residence (home).

DESIGN

Prospective cohort study reviewing OHCA from July 1989 to December 1993. Variables were age, witnessed arrest, response intervals, automated external defibrillator (AED) use, and arrest rhythms. Outcomes were hospital admission and discharge. Pearson chi-square was used for analysis.

SETTING

Suburban EMS system.

SUBJECTS

Patients > or = 19 years old with arrest of presumed cardiac cause, with locations at home or at a NH.

RESULTS

2,348 total arrests were complete for analysis, 182 at a NH and 2,166 at home. BLS and ALS response intervals were shorter for the NH patients. The NH patients were more likely to receive CPR on collapse, were older (73.1 vs 67.5 years, p < 0.001), were less likely to have had an AED used (9.9% vs 30.0%, p < 0.001), and were more likely to have an arrest bradyasystolic rhythm (74.7% vs 51.5%, p < 0.001). They were less likely to survive to hospital admission (10.4% vs 18.5%, p < 0.006) and discharge (0.0% vs 5.6%, p < 0.001).

CONCLUSION

During this four-and-a-half-year study period, no NH patient survived, even though % CPR was increased. Arrest rhythm is an important factor in this finding. EMS initial care for ventricular tachycardia/fibrillation NH patients, with less application of AEDs, was identified. This different response may adversely contribute to dismal NH outcome.

Limiting treatment in nursing homes: knowledge and attitudes of nursing home medical directors

OBJECTIVE

To determine nursing home medical directors' knowledge about cardiopulmonary resuscitation outcome and their support of treatment limitation requests and policies.

DESIGN

Mailed questionnaire, followed by telephone interview.

PARTICIPANTS

Forty-six medical directors of 70 community nursing homes in Harris County, Texas.

MEASUREMENTS

Medical directors were asked to estimate the CPR survival rate to discharge of all nursing home residents and that of two case scenarios. They were asked to indicate on a Likert scale their support for mandatory Do-Not-Resuscitate orders and for requests by nursing home patients to withhold other life support measures.

RESULTS

Responses were received from 33 directors. Overall CPR survival rate of older nursing home residents after cardiac arrest was thought to be 10.7%. The average CPR survival rate for healthy older people with witnessed arrests was believed to be 13.8%. The perceived rate for unwitnessed arrests in terminal patients was 4.6%, significantly lower than estimates for healthy older people (P = .003) and estimates of the overall survival rate (P = .02). Medical directors were split regarding mandatory Do-Not-Resuscitate orders for patients in vegetative states, with terminal illness, with an unwitnessed arrest, or in those older than 90 years of age. Mandatory use of Do-Not-Resuscitate orders for all nursing home residents was strongly opposed. Assuming a 2% survival rate did not significantly influence medical directors' opinions about mandatory DNR orders in these groups. Medical directors were more willing to support requests by stable nursing home residents to withhold resuscitation, mechanical ventilation, or hospitalization than requests to withhold antibiotics, intravenous fluids, or tube feedings (P < .005). The majority of medical directors were willing to withhold all such measures for terminal patients.

CONCLUSIONS

Health care professionals who are responsible for educating patients about the efficacy of cardiopulmonary resuscitation in nursing homes overestimate its benefit and may benefit from further education about its outcome. Although mandatory Do-Not-Resuscitate orders were favored for terminal or vegetative patients, medical directors are not supportive of such orders across the board. Medical directors are more willing to honor requests for treatment limitation by terminal patients than others.

Code status decision-making in a nursing home population: processes and outcomes

OBJECTIVES

To examine the clinical utility of prehospital code status discussions in a nursing home (NH) setting and the health care outcomes of the decisions made. Also to identify patient factors and other variables associated with these decisions.

DESIGN

Retrospective uncontrolled observational study carried out through record review.

SETTING

A single skilled-level teaching NH and its affiliated university hospital.

PATIENTS

All of the 350 individuals who resided at the NH during a 2-year period.

MAIN RESULTS

Code status decisions were routinely sought through discussion involving primary care physician/social worker teams and residents or surrogates of demented patients. Choices were made for 80% of the NH residents, most (73%) by surrogates and most (80%) for do-not-resuscitate (DNR) orders, usually within 10 weeks of NH admission. Neither short-term measures of NH care intensity nor hospital use changed after a DNR decision. Most (80%) hospital transfer records included code status documentation. At the NH, both the likelihood of decisions and their directions were associated with involvement by specific physician/social worker teams. Additionally, a dementia diagnosis, white race, and older age were associated with a nursing home DNR decision. At the hospital, a DNR order was associated with white race, the presence of nursing home DNR documentation in the transfer records, hospital attending care by certain NH physicians, and a terminal hospital stay. Hospital inpatient medical and surgical therapy use, except for intensive care procedures, was similar for DNR and non-DNR inpatients. Residents with DNR orders had a higher mortality rate, yet most survived at least 1 year after the order. In the short term, a DNR order had no impact on measured health care resource consumption, but, for those in the final months of life, in-patient hospital use was less for the DNR group, and most of these died at the nursing home.

CONCLUSIONS

Prehospital code status decisions can be made effectively within the NH setting. Outside of medical intensive care, DNR orders have no impact on NH and hospital care intensity in the short term. In the final 6 months of life, however, hospital use is less for the DNR subgroup.

Outcomes of cardiopulmonary resuscitation in nursing homes: can we predict who will benefit?

PURPOSE

To determine the benefits of cardiopulmonary resuscitation (CPR) in nursing home patients and assess possible prearrest and arrest predictors of survival.

PATIENTS AND METHODS

During a 4-year period (1986 to 1989), consecutive nursing home patients from Milwaukee, Wisconsin, who sustained cardiac arrest and received CPR by paramedics were studied. The patients' prearrest clinical characteristics were determined including age, length of stay in nursing home, medical diagnoses, medications, circumstances surrounding the arrest, laboratory studies, and baseline functional status. Cardiac arrest data were obtained from a paramedic computer data base and included whether the arrest was witnessed, initial cardiac rhythm, and success of CPR. Survival was defined as the discharge of the patient alive from the hospital, and the patient's pre- and post-arrest functional status was compared. Possible predictors of survival were analyzed from the patient's prearrest characteristics and arrest characteristics.

RESULTS

Of the total 196 patients who received CPR, 37 (19%) were successfully resuscitated and hospitalized, and 10 (5%) survived to be discharged. However, 27% of patients survived whose arrests were witnessed and who demonstrated ventricular fibrillation at the time of the arrest. In comparison, only 2.3% of all other nursing home patients who received CPR survived (p < 0.0002). Age, mental or functional status, hematocrit, renal dysfunction, pulmonary disease, cancer, and cardiovascular disease were not significant predictors of survival. At the time of hospital discharge, the functional status of the majority (80%) of the survivors was comparable to their prearrest status and 40% of the survivors lived for greater than 12 months.

CONCLUSION

We conclude that only a small percentage of nursing home patients who sustain cardiac arrest will benefit from CPR. However, greater than 25% of nursing home patients whose arrest is witnessed and who demonstrate ventricular fibrillation will survive. This is comparable to the survival rate of elderly community-dwelling persons who sustain cardiac arrest. Our data suggest that CPR should be initiated only in nursing home patients whose cardiac arrest is witnessed and should only be continued in patients whose initial documented cardiac rhythm is ventricular fibrillation or ventricular tachycardia.

Utilization of cardiopulmonary resuscitation in nursing homes in one community: rates and nursing home characteristics

OBJECTIVE

To determine the rate of cardiopulmonary resuscitation use among all nursing homes in a large urban area, to examine CPR use over time, to discover whether CPR use varies among nursing homes, and to describe characteristics of patients undergoing CPR.

DESIGN

Retrospective survey.

SETTING

Nursing homes in a large urban area.

PARTICIPANTS

One hundred ninety-six nursing home residents of 68 nursing homes underwent cardiopulmonary resuscitation over a 4-year period (1986-1989). Over this time there were 9,486 deaths in these homes, which comprised 10,252 beds.

MEASUREMENTS

The CPR:death ratio was determined for each facility. The ratio was analyzed over time and by type of facility (eg, proprietary, non-profit, size of facility). The ratio was also examined among facilities with variable death rates. Patients undergoing CPR are described.

RESULTS

The ratio of CPR:death over the 4-year period was 0.02. CPR:death ratio was higher (0.03) for the proprietary homes compared with the non-profit homes (0.01) P < 0.0001. A significant downward trend of CPR:death was noted over the study period for the non-profit homes; no such trend was noted in the proprietary homes. Size of nursing home did not influence the rate of CPR use. Homes with greater numbers of deaths per bed had a lower utilization of CPR. Patients undergoing CPR were old, frail, and had multiple medical problems. CPR attempts were frequent around the time of nursing home admission.

CONCLUSION

The utilization of CPR in nursing homes is quite low. Non-profit homes utilize CPR less than proprietary homes. Nursing homes with the highest numbers of deaths per bed utilize CPR less than homes with lower numbers of deaths per bed. Nursing home residents receiving CPR are quite old, have multiple illnesses, and are impaired.
