Adult Children and the Transition of Aging Parents

Abstract

This study explores the experiences of adult children as they transition their functionally and/or cognitively declining aging parents from independent living to supervised housing. A qualitative grounded theory approach was used to chronicle the experiences of adult children as their caregiving responsibilities intensified and their parents' health declined. Purposive, snowball sampling was used to enlist adult children (n = 16) who were in the process of transitioning an aging parent from an independent living situation to one providing assistance with everyday care and tasks. Semi-structured telephone interviews were conducted and designed to follow a pattern of increased frailty of the parent(s) and escalating involvement of the adult child. Two major themes emerged from the data: Changing places and everlasting love. Adult children began to intervene when cognitive or physical declines compromised the safety and well-being of the older adult and began to assume responsibility for day-to-day needs. As disabilities intensified, adult children relied on siblings, friends, social services, and health care providers to assist in planning and implementing caregiving responsibilities. Deep respect and abiding love of the aging parent(s) sustained the adult child throughout the caregiving experience.     

A Systematic Review of Palliative Care Intervention Outcomes and Outcome Measures in Low-Resource Countries

Context

To meet the growing need for palliative care in low-resource countries, palliative care programs should be evidence based and contextually appropriate. This study was conducted to synthesize the current evidence to guide future programmatic and research efforts.

Impact of socio-economic status on hospital length of stay following injury: a multicenter cohort study

Background

Injury is second only to cardiovascular disease in terms of acute care costs in North America. One key to improving injury care efficiency is to generate knowledge on the determinants of resource use. Socio-economic status (SES) is a documented risk factor for injury severity and mortality but its impact on length of stay (LOS) for injury admissions is unknown. This study aimed to examine the relationship between SES and LOS following injury.This multicenter retrospective cohort study was based on adults discharged alive from any trauma center (2007–2012; 57 hospitals; 65,486 patients) in a Canadian integrated provincial trauma system. SES was determined using ecological indices of material and social deprivation. Mean differences in LOS adjusted for age, gender, comorbidities, and injury severity were generated using multivariate linear regression.

Results

Mean LOS was 13.5 days. Patients in the highest quintile of material/social deprivation had a mean LOS 0.5 days (95 % CI 0.1-0.9)/1.4 days (1.1-1.8) longer than those in the lowest quintile. Patients in the highest quintiles of both social and material deprivation had a mean LOS 2.6 days (1.8-3.5) longer than those in the lowest quintiles.

Conclusions

Results suggest that patients admitted for traumatic injury who suffer from high social and/or material deprivation have longer acute care LOS in a universal-access health care system. The reasons behind observed differences need to be further explored but may indicate that discharge planning should take patient SES into consideration.

     

Cost-effectiveness of screening with B-type natriuretic peptide to identify patients with reduced left ventricular ejection fraction

OBJECTIVES: This study was designed to evaluate the cost-effectiveness of screening patients with a B-type natriuretic peptide (BNP) blood test to identify those with depressed left ventricular systolic function. BACKGROUND: Asymptomatic patients with depressed ejection fraction (EF) may have less progression to heart failure if they can be identified and treated. METHODS: We used a decision model to estimate economic and health outcomes for different screening strategies using BNP and echocardiography to detect left ventricular EF <40% for men and women age 60 years. We used published data from community cohorts (gender-specific BNP test characteristics, prevalence of depressed EF) and randomized trials (benefit from treatment). RESULTS: Screening 1,000 asymptomatic patients with BNP followed by echocardiography in those with an abnormal test increased the lifetime cost of care (176,000 US dollars for men, 101,000 US dollars for women) and improved outcome (7.9 quality-adjusted life years [QALYs] for men, 1.3 QALYs for women), resulting in a cost per QALY of 22,300 US dollars for men and 77,700 US dollars for women. For populations with a prevalence of depressed EF of at least 1%, screening with BNP followed by echocardiography increased outcome at a cost < 50,000 US dollars per QALY gained. Screening would not be attractive if a diagnosis of left ventricular dysfunction led to significant decreases in quality of life or income. CONCLUSIONS: Screening populations with a 1% prevalence of reduced EF (men at age 60 years) with BNP followed by echocardiography should provide a health benefit at a cost that is comparable to or less than other accepted health interventions.     

The prognostic importance of different definitions of worsening renal function in congestive heart failure

BACKGROUND: Worsening renal function in patients hospitalized for heart failure portends a poor prognosis. However, criteria used to define worsening renal function are arbitrary, and the implications of different definitions remain unclear. We therefore compared the prognostic importance of various definitions of worsening renal function in 1,002 patients hospitalized for congestive heart failure (CHF). METHODS AND RESULTS: The patient population was 49% female, aged 67 +/- 15 years. Twenty-three percent had a prior history of renal failure, 73% had known depressed ejection fraction, and 63% had known CHF. On admission to the hospital, 47% were receiving ACE inhibitors, 22% beta-blockers, 70% diuretics and 6% NAID's. 72% developed increased serum creatinine during the hospitalization, with 20% developing an increase of > or = 0.5 mg/dL. Worsening renal function predicted both in-hospital mortality and length of stay > 10 days. Even an increased creatinine of 0.1 mg/dL was associated with worse outcome. Sensitivity for death decreased from 92% to 65% as the threshold for increased creatinine was raised from 0.1 to 0.5 mg/dL, with specificity increasing from 28% to 81%. At a threshold of a 0.3 mg/dL increase, sensitivity was 81% and specificity was 62% for death and 64% and 65% for length of stay >10 days. Adding a requirement of final creatinine of > or = 1.5 mg/dL improved specificity. CONCLUSIONS: This analysis demonstrates that any detectable decrease in renal function is associated with increased mortality and prolonged hospital stay. This suggests that therapeutic interventions which improve renal function might be beneficial.     

Prognostic judgments and triage decisions for patients with acute congestive heart failure

STUDY OBJECTIVES: To determine how well triage physicians judge the probability of death or severe complications that require treatment only available in an ICU to maintain life for patients with acute congestive heart failure (CHF). DESIGN: Prospective cohort study. SETTING: An urban university hospital, a Veteran's Administration hospital, and a community hospital. Patients or participants: Patients were those visiting the emergency department (ED) with acute CHF, excluding those who already required a treatment only available in an ICU to maintain life, and those with possible or definite myocardial infarction. Physician participants were those caring for the patients in the ED. MEASUREMENTS AND RESULTS: We performed chart reviews to ascertain whether each patient died or had severe complications develop by 4 days. We collected judgments of the probability of this outcome from the physicians taking care of the study patients in the ED. The prevalence of death or severe complications was 43 per 1,032 patients (4.2%). The mean +/- SD of physicians' judgments of the probability of this outcome was 32.1 +/- 28.4%. A calibration curve that stratified these judgments by decile demonstrated that physicians consistently overestimated this probability (p < 0.01). Physicians' judgments were only moderately good at discriminating which patients would have the outcome (receiver operating characteristic curve area, 0.715). Patients admitted to an ICU received the highest average predicted probability (56.4%), followed by those admitted to a telemetry unit (34.1%), to a regular hospital ward (29.8%), and those sent home (17.9%.) CONCLUSIONS: Physicians drastically overestimated the probability of a severe complication that would require critical care for patients with acute CHF who were candidates for ICU admission. Their judgments of this probability were associated with their triage decisions, as they should be according to several guidelines for ICU triage. Overestimation of the probability of severe complications may have lead to overutilization of scarce critical care resources. Current critical care triage guidelines should be revised to take this difficulty into account, and better predictive models for patients potentially requiring critical care should be developed.     

Skin involvement in juvenile dermatomyositis is associated with loss of end row nailfold capillary loops

OBJECTIVE: To determine associations of dermatological findings in children with juvenile dermatomyositis (JDM) with specific nailfold capillary (NFC) structural abnormalities. METHODS: Sixty newly diagnosed, previously untreated children who met the Bohan-Peter criteria for definite JDM were seen between 1993 and 2002. They were classified by duration of untreated disease and by a disease activity score (DAS) composed of separate subscores for dermatological (DAS skin) and musculoskeletal (DAS muscle) findings. Routine NFC measurements yielded the number of end row loops, arboreal (bushy), and dilated capillary loops. Laboratory testing included muscle enzymes, von Willebrand Factor Antigen, and neopterin. RESULTS: DAS skin, but not DAS muscle, was associated with NFC end row capillary loss (rs = -0.394, p = 0.008). End row capillary loss (reflecting avascularity), arboreal (bushy), and dilated capillary loops (reflecting change in vascular morphology) were each associated with longer untreated symptom duration (rs = -0.401, rs = 0.534, rs = 0.371). CONCLUSION: End row capillary loss measured by NFC was associated with the dermatological, but not musculoskeletal manifestations of JDM, suggesting that damage to skin and muscle may each have distinct disease pathophysiology. In JDM, skin involvement indicates a vasculopathy that progresses with increasing duration of untreated disease and is not revealed by standard serological laboratory tests. We propose that the cutaneous manifestations of JDM are associated with vascular disease and warrant aggressive therapy.     

Angiographically silent left main disease detected by intravascular ultrasound: a marker for future adverse cardiac events

Background

Concomitant moderate obstructive left main (LM) disease is associated with future cardiac events and poor prognosis in patients undergoing percutaneous intervention (PCI). Whether prognosis is similarly effected by LM disease not detected by angiography, but evident on intravascular ultrasound (IVUS) imaging, is not known. The purpose of this study was to evaluate the long-term prognosis of patients with angiographically insignificant LM coronary artery disease undergoing PCI.

Methods and results

One hundred and seven consecutive patients undergoing PCI with angiographically normal or mild LM disease had 2- and 3-dimensional IVUS imaging. IVUS images were digitized, and 3-dimensional reconstruction was performed. Percent diameter and area stenosis by angiography were 4.8% ± 3.5% and 18.2% ± 9.8%, respectively. IVUS mean luminal area and area stenosis were 17.9 ± 5.6 mm² and 30.2% ± 14.7%, respectively. Long-term follow-up was available in 102 (95%) patients at a median of 29 (range 8-52) months. Major adverse cardiac events, defined as death (6), myocardial infarction (4), repeat PCI (13), or CABG (16), were associated with female sex (P = .04), diabetes (P = .02), angiographic minimum lumen diameter (P = .04), and IVUS minimum (P = .01) and mean (P = .01) lumen area. Multivariate predictors of late cardiac events were diabetes (hazard ratio 2.69, P = .014) and minimum lumen area by IVUS (hazard ratio 0.59, P = .015).

Conclusions

Despite being angiographically silent, LM disease detected by IVUS is an independent predictor of cardiac events and may serve as a marker for such events. These data extend the spectrum of LM disease severity and its relationship to cardiac prognosis in patients undergoing PCI.
