Systematic Literature Review of Health-Related Quality-of-Life Measures for Caregivers of Older Adult Trauma Patients

INTRODUCTION

As the older adult population increases, hospitals treat more older adults with injuries. After leaving, these patients suffer from decreased mobility and independence, relying on care from others. Family members often assume this responsibility, mostly informally and unpaid. Caregivers of other older adult populations have increased stress and decreased caregiver-related quality of life (CRQoL). Validated CRQoL measures are essential to capture their unique experiences. Our objective was to review existing CRQoL measures and their validity in caregivers of older adult trauma patients.

METHODS

A professional librarian searched published literature from the inception of databases through August 12, 2022 in MEDLINE (via PubMed), Embase (via Elsevier), and CINAHL Complete (via EBSCO). We identified 1063 unique studies of CRQoL in caregivers for adults with injury and performed a systematic review following COnsensus-based Standards for the selection of health Measurement Instruments guidelines for CRQoL measures.

RESULTS

From the 66 studies included, we identified 54 health-related quality-of-life measures and 60 domains capturing caregiver-centered concerns. The majority (83%) of measures included six or fewer CRQoL content domains. Six measures were used in caregivers of older adults with single-system injuries. There were no validated CRQoL measures among caregivers of older adult trauma patients with multisystem injuries.

CONCLUSIONS

While many measures exist to assess healthcare-related quality of life, few, if any, adequately assess concerns among caregivers of older adult trauma patients. We found that CRQoL domains, including mental health, emotional health, social functioning, and relationships, are most commonly assessed among caregivers. Future measures should focus on reliability and validity in this specific population to guide interventions.

Central nervous system medication use around hospitalization

BACKGROUND

Central nervous system (CNS) medication use is common among older adults, yet the impact of hospitalizations on use remains unclear. This study details CNS medication use, discontinuations, and user profiles during hospitalization periods.

METHODS

Retrospective cohort study using electronic health records on patients ≥65 years, from three hospitals (2018-2020), and prescribed a CNS medication around hospitalization (90 days prior to 90 days after). Latent class transitions analysis (LCTA) examined profiles of CNS medication class users across four time points (90 days prior, admission, discharge, 90 days after hospitalization).

RESULTS

Among 4666 patients (mean age 74.3 ± 9.3 years; 63% female; 70% White; mean length of stay 4.6 ± 5.6 days (median 3.0 [2.0, 6.0]), the most commonly prescribed CNS medications were antidepressants (56%) and opioids (49%). Overall, 74% (n = 3446) of patients were persistent users of a CNS medication across all four time points; 7% (n = 388) had discontinuations during hospitalization, but of these, 64% (216/388) had new starts or restarts within 90 days after hospitalization. LCTA identified three profile groups: (1) low CNS medication users, 54%-60% of patients; (2) mental health medication users, 30%-36%; and (3) acute/chronic pain medication users, 9%-10%. Probability of staying in same group across the four time points was high (0.88-1.00). Transitioning to the low CNS medication use group was highest from admission to discharge (probability of 9% for pain medication users, 5% for mental health medication users). Female gender increased (OR 2.4, 95% CI 1.3-4.3), while chronic kidney disease lowered (OR 0.5, 0.2-0.9) the odds of transitioning to the low CNS medication use profile between admission and discharge.

CONCLUSIONS

CNS medication use stays consistent around hospitalization, with discontinuation more likely between admission and discharge, especially among pain medication users. Further research on patient outcomes is needed to understand the benefits and harms of hospital deprescribing, particularly for medications requiring gradual tapering.

Bacteremia From a Presumed Urinary Source in Hospitalized Adults With Asymptomatic Bacteriuria

Importance

Guidelines recommend withholding antibiotics in asymptomatic bacteriuria (ASB), including among patients with altered mental status (AMS) and no systemic signs of infection. However, ASB treatment remains common.

Objectives

To determine prevalence and factors associated with bacteremia from a presumed urinary source in inpatients with ASB with or without AMS and estimate antibiotics avoided if a 2% risk of bacteremia were used as a threshold to prompt empiric antibiotic treatment of ASB.

Design, Setting, and Participants

This cohort study assessed patients hospitalized to nonintensive care with ASB (no immune compromise or concomitant infections) in 68 Michigan hospitals from July 1, 2017, to June 30, 2022. Data were analyzed from August 2022 to January 2023.

Main Outcomes and Measures

The primary outcome was prevalence of bacteremia from a presumed urinary source (ie, positive blood culture with matching organisms within 3 days of urine culture). To determine factors associated with bacteremia, we used multivariable logistic regression models. We estimated each patient's risk of bacteremia and determined what percentage of patients empirically treated with antibiotics had less than 2% estimated risk of bacteremia.

Results

Of 11 590 hospitalized patients with ASB (median [IQR] age, 78.2 [67.7-86.6] years; 8595 female patients [74.2%]; 2235 African American or Black patients [19.3%], 184 Hispanic patients [1.6%], and 8897 White patients [76.8%]), 8364 (72.2%) received antimicrobial treatment for UTI, and 161 (1.4%) had bacteremia from a presumed urinary source. Only 17 of 2126 patients with AMS but no systemic signs of infection (0.7%) developed bacteremia. On multivariable analysis, male sex (adjusted odds ratio [aOR], 1.45; 95% CI, 1.02-2.05), hypotension (aOR, 1.86; 95% CI, 1.18-2.93), 2 or more systemic inflammatory response criteria (aOR, 1.72; 95% CI, 1.21-2.46), urinary retention (aOR, 1.87; 95% CI, 1.18-2.96), fatigue (aOR, 1.53; 95% CI, 1.08-2.17), log of serum leukocytosis (aOR, 3.38; 95% CI, 2.48-4.61), and pyuria (aOR, 3.31; 95% CI, 2.10-5.21) were associated with bacteremia. No single factor was associated with more than 2% risk of bacteremia. If 2% or higher risk of bacteremia were used as a cutoff for empiric antibiotics, antibiotic exposure would have been avoided in 78.4% (6323 of 8064) of empirically treated patients with low risk of bacteremia.

Conclusions and Relevance

In patients with ASB, bacteremia from a presumed urinary source was rare, occurring in less than 1% of patients with AMS. A personalized, risk-based approach to empiric therapy could decrease unnecessary ASB treatment.

Association of prior treatment with nitrogen-containing bisphosphonates on outcomes of COVID-19 positive patients

COVID-19 infection has resulted in significant morbidity and mortality globally, especially among older adults. Repurposed drugs have demonstrated activity in respiratory illnesses, including nitrogen-containing bisphosphonates. In this retrospective longitudinal study at 4 academic medical centers, we show no benefit of nitrogen-containing bisphosphonates regarding ICU admission, ventilator use, and mortality among older adults with COVID-19 infection. We specifically evaluated the intravenous bisphosphonate zoledronic acid and found no difference compared to oral bisphosphonates.

BACKGROUND

Widely used in osteoporosis treatment, nitrogen-containing bisphosphonates (N-BP) have been associated with reduced mortality and morbidity among older adults. Based on prior studies, we hypothesized that prior treatment with N-BP might reduce intensive care unit (ICU) admission, ventilator use, and death among older adults diagnosed with COVID-19.

METHODS

This retrospective analysis of the PCORnet Common Data Model across 4 academic medical centers through 1 September 2021 identified individuals age >50 years with a diagnosis of COVID-19. The composite outcome included ICU admission, ventilator use, or death within 15, 30, and 180 days of COVID-19 diagnosis. Use of N-BP was defined as a prescription within 3 years prior. ICU admission and ventilator use were determined using administrative codes. Death included both in-hospital and out-of-hospital events. Patients treated with N-BP were matched 1:1 by propensity score to patients without prior N-BP use. Secondary analysis compared outcomes among those prescribed zoledronic acid (ZOL) to those prescribed oral N-BPs.

RESULTS

Of 76,223 COVID-19 patients identified, 1,853 were previously prescribed N-BP, among whom 559 were prescribed ZOL. After propensity score matching, there were no significant differences in the composite outcome at 15 days (HR 1.22, 95% CI: 0.89-1.67), 30 days (HR 1.24, 95% CI: 0.93-1.66), or 180 days (HR 1.17, 95% CI: 0.93-1.48), comparing those prescribed and not prescribed N-BP. Compared to those prescribed oral N-BP, there were no significant differences in outcomes among those prescribed ZOL.

CONCLUSION

Among older COVID-19 patients, prior exposure to N-BP including ZOL was not associated with a reduction in ICU admission, ventilator use, or death.

Ageing and physical resilience after health stressors

The objectives of this article are to introduce a conceptual framework for physical resilience in the context of ageing and to discuss key elements and challenges in the design of studies of physical resilience after health stressors. Advancing age is associated with increasing exposure to multiple stressors and declining capacity to respond to health stressors. Resilience is defined broadly as the ability to resist or recover well from the adverse effects of a health stressor. In ageing-related study designs of physical resilience after a health stressor, this dynamic resilience response can be observed as changes in repeated measures of function or health status in various domains important to older adults. Methodologic issues in selecting the study population, defining the stressor, covariates, outcomes, and analytic strategies are highlighted in the context of an ongoing prospective cohort study of physical resilience after total knee replacement surgery. The article concludes with approaches to intervention development to optimize resilience.

Research objectives and general considerations for pragmatic clinical trials of pain treatments: IMMPACT statement

ABSTRACT

Many questions regarding the clinical management of people experiencing pain and related health policy decision-making may best be answered by pragmatic controlled trials. To generate clinically relevant and widely applicable findings, such trials aim to reproduce elements of routine clinical care or are embedded within clinical workflows. In contrast with traditional efficacy trials, pragmatic trials are intended to address a broader set of external validity questions critical for stakeholders (clinicians, healthcare leaders, policymakers, insurers, and patients) in considering the adoption and use of evidence-based treatments in daily clinical care. This article summarizes methodological considerations for pragmatic trials, mainly concerning methods of fundamental importance to the internal validity of trials. The relationship between these methods and common pragmatic trials methods and goals is considered, recognizing that the resulting trial designs are highly dependent on the specific research question under investigation. The basis of this statement was an Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) systematic review of methods and a consensus meeting. The meeting was organized by the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership. The consensus process was informed by expert presentations, panel and consensus discussions, and a preparatory systematic review. In the context of pragmatic trials of pain treatments, we present fundamental considerations for the planning phase of pragmatic trials, including the specification of trial objectives, the selection of adequate designs, and methods to enhance internal validity while maintaining the ability to answer pragmatic research questions.

An Analysis of how Herpes Zoster Pain affects Health Related Quality of Life of Placebo subjects from Three Randomized Phase III Studies

OBJECTIVES

Herpes Zoster (HZ) is a painful condition caused by reactivation of the varicella zoster virus, negatively impacting the lives of patients. In this post-hoc analysis, we describe the impact of HZ pain on the Health-Related Quality of Life (HRQoL) and Activities of Daily Living (ADL) of immunocompetent individuals ≥50 years of age (YOA) and in Hematopoietic Stem Cell Transplantation (HSCT) recipients aged ≥18 YOA.

METHODS

ZOE-50 (NCT01165177), ZOE-70 (NCT01165229) and ZOE-HSCT (NCT01610414) were phase III, randomized studies conducted in immunocompetent adults ≥50 YOA and ≥70 YOA and in HSCT recipients aged ≥18 YOA, respectively. This analysis was performed on subjects who experienced a HZ episode in the placebo groups. The impact of varying levels of HZ pain on HRQoL and ADL was analyzed using data from the Zoster Brief Pain Inventory (ZBPI) and the SF-36 and EQ-5D questionnaires.

RESULTS

520 immunocompetent and 172 HSCT individuals with HZ were included. SF-36 and EQ-5D domain scores showed a significant relationship between increased HZ pain and worsening HRQoL. For every increase of 1 in the ZBPI pain score, the estimated mean decrease (worsening) in score in the ZOE-50/70 and ZOE-HSCT, respectively, was 2.0 and 2.4 for SF-36 Role Physical; 2.1 and 1.8 for SF-36 Social Functioning; and 0.041 and 0.045 for EQ-5D utility. Sleep and General activities were the ADL components most affected.

DISCUSSION

Moderate and severe HZ pain had a substantial negative impact on all aspects of HRQoL and ADL. This impact was independent of age and immunosuppression.

Using the COM-B model to identify barriers to and facilitators of evidence-based nurse urine-culture practices

Our surveys of nurses modeled after the Capability, Opportunity, and Motivation Model of Behavior (COM-B model) revealed that opportunity and motivation factors heavily influence urine-culture practices (behavior), in addition to knowledge (capability). Understanding these barriers is a critical step towards implementing targeted interventions to improving urine-culture practices.

Natural History of Herpes Zoster in the Placebo Groups of Three Randomized Phase III Clinical Trials

INTRODUCTION

The risk of herpes zoster (HZ) is associated with a decline in immune system function, linked to aging and/or immunocompromising or immunosuppressive diseases or therapies. In this post hoc analysis we describe the incidence of HZ, rash characteristics, and burden of HZ pain in immunocompetent adults ≥ 50 years of age (YOA) and in hematopoietic stem cell transplantation (HSCT) recipients ≥ 18 YOA.

METHODS

ZOE-50 (NCT01165177), ZOE-70 (NCT01165229), and ZOE-HSCT (NCT01610414) were phase III, observer-blind, placebo-controlled, randomized studies conducted in immunocompetent adults ≥ 50 YOA and ≥ 70 YOA; and in HSCT recipients ≥ 18 YOA, respectively. A similar methodology for study design, case definition, and data collection were applied in all three studies. The participants received either two doses of the adjuvanted recombinant zoster vaccine or placebo, 1-2 months apart. This analysis focuses on all confirmed HZ cases from the placebo groups of the three studies. HZ pain and interference with activities of daily living were assessed using the Zoster Brief Pain Inventory instrument.

RESULTS

Overall, 280, 240, and 172 placebo participants with an HZ confirmed episode aged ≥ 50, ≥ 70, and ≥ 18 YOA were included in the ZOE-50, ZOE-70, and ZOE-HSCT analyses, respectively. The incidence of HZ was 9.1/1000 person-years in both the ZOE-50 and ZOE-70 placebo groups and 95.6/1000 person-years in the ZOE-HSCT study placebo group. In the three studies, most individuals with HZ had severe pain, with approximately 90% of individuals reporting clinically significant pain. An estimated 12.3%, 16.9%, and 21.8% of patients in the ZOE-50, ZOE-70, and ZOE-HSCT studies, respectively, developed post-herpetic neuralgia.

CONCLUSION

The incidence and burden of HZ is high in immunocompetent adults aged ≥ 50 YOA and even more so in HSCT recipients aged ≥ 18 YOA.

Caregiver-Assisted Pain Coping Skills Training for Patients With Dementia: A Pilot Study

Pain is common and undertreated in patients with dementia, and contributes to disability, psychological distress, neuropsychiatric symptoms and caregiver stress. The goal of this study was to develop a caregiver-assisted pain coping skills training protocol tailored for community-dwelling adults with mild-moderate dementia and their family caregivers. We conducted interviews with patients and caregivers to develop the protocol. We then conducted a single arm pilot test of the intervention’s feasibility and acceptability. Patients were recruited from an outpatient memory care clinic and screened for pain using the validated Pain, Enjoyment, General Activity (PEG) scale. The intervention included five sessions of training in pain assessment, relaxation, pleasant activity scheduling, and integrative movement. Initially sessions were conducted in person or by videoconference according to the dyad’s preference; during COVID-19 (latter half of study) all sessions were conducted remotely. Eleven dyads consented and provided baseline data [patients: mean age=77.7 years (SD=4.8), 70% non-Hispanic white; caregivers: mean age=69.6 years (SD=13.3); 91% non-Hispanic white; 73% spouses]. Nine dyads (82%) completed all five sessions. Caregivers reported high levels of satisfaction with the intervention (mean=3.4 on 1-4 scale) and frequent use of pain coping skills (mean=3-4 days/week). On average, patients reported pre-post decreases in pain severity (mean=-1.2, SD=1.8) and pain interference (mean=-0.64, SD=0.67) on the Brief Pain Inventory. Overall these findings suggest that a behavioral pain coping intervention for patients with mild-moderate dementia and their caregivers is feasible, acceptable, and potentially helpful for managing pain.

A template for physical resilience research in older adults: Methods of the PRIME-KNEE study

BACKGROUND

Older adults with similar health conditions often experience widely divergent outcomes following health stressors. Variable recovery after a health stressor may be due in part to differences in biological mechanisms at the molecular, cellular, or system level, that are elicited in response to stressors. We describe the PRIME-KNEE study as an example of ongoing research to validate provocative clinical tests and biomarkers that predict resilience to specific health stressors.

METHODS

PRIME-KNEE is an ongoing, prospective cohort study that will enroll 250 adults ≥60 years undergoing total knee arthroplasty. Data are collected at baseline (pre-surgery), during surgery, daily for 7 days after surgery, and at 1, 2, 4, and 6 months post-surgery. Provocative tests include a cognition-motor dual-task walking test, cerebrovascular reactivity assessed by functional near-infrared spectroscopy, peripheral blood mononuclear cell reactivity ex vivo to lipopolysaccharide toxin and influenza vaccine, and heart rate variability during surgery. Cognitive, psychological, and physical performance batteries are collected at baseline to estimate prestressor reserve. Demographics, medications, comorbidities, and stressor characteristics are abstracted from the electronic medical record and via participant interview. Blood-based biomarkers are collected at baseline and postoperative day 1. Repeated measures after surgery include items from a delirium assessment tool and pain scales administered daily by telephone for 7 days and cognitive change index (participant and informant), lower extremity activities of daily living, pain scales, and step counts assessed by Garmin actigraphy at 1, 2, 4, and 6 months after surgery. Statistical models use these measures to characterize resilience phenotypes and evaluate prestressor clinical indicators associated with poststressor resilience.

CONCLUSION

If PRIME-KNEE validates feasible clinical tests and biomarkers that predict recovery trajectories in older surgical patients, these tools may inform surgical decision-making, guide pre-habilitation efforts, and elucidate mechanisms underlying resilience. This study design could motivate future geriatric research on resilience.

Immunogenicity and safety of different dose schedules and antigen doses of an MF59-adjuvanted H7N9 vaccine in healthy adults aged 65 years and older

BACKGROUND

The number of human influenza A (H7N9) infections has escalated since 2013 with high resultant mortality. We conducted a phase II, randomized, partially-blinded trial to evaluate the safety and immunogenicity of an MF59-adjuvanted inactivated, split virion, H7N9 influenza vaccine (H7N9 IIV) administered at various dose levels and schedules in older adults.

METHODS

479 adults ≥ 65 years of age in stable health were randomized to one of six groups to receive either 3.75, 7.5 or 15 µg of influenza A/Shanghai/02/2013 (H7N9) IIV adjuvanted with MF59 given as a 3-dose series either on days 1, 28 and 168 or on days 1, 57 and 168. Immunogenicity was assessed using both hemagglutination inhibition (HAI) and microneutralization (MN) assays prior to and 28 days following each dose. Safety was assessed through 1 year following the last dose.

RESULTS

Subjects in all groups had only modest immune responses, with the HAI GMT < 20 after the second vaccine dose and <29 after the third vaccine dose. HAI titers ≥ 40 were seen in <37% of subjects after the second dose and <49% after the third dose. There were no significant differences seen between the two dose schedules. MN titers followed similar patterns, although the titers were approximately two-fold higher than the HAI titers. Logistic regression modeling demonstrated no statistically significant associations between the immune responses and age, sex or body mass index whereas recent prior receipt of seasonal influenza vaccine significantly reduced the HAI response [OR 0.13 (95% CI 0.05, 0.33); p < 0.001]. Overall, the vaccine was well tolerated. Two mild potentially immune mediated adverse events occurred, lichen planus and guttate psoriasis.

CONCLUSIONS

MF59-adjuvanted H7N9 IIV was only modestly immunogenic in the older adult population following three doses. There were no significant differences in antibody responses noted among the various antigen doses or the two dose schedules.

Infections in Older Adults: A Case-Based Discussion Series Emphasizing Antibiotic Stewardship

INTRODUCTION

Compared with younger populations, adults 65 years and older are more likely to suffer infection-related morbidity and mortality, experience antibiotic-related adverse events, and acquire multidrug-resistant organisms. We developed a series of case-based discussions that stressed antibiotic stewardship while addressing management of common infections in older adults.

METHODS

Five 1-hour case-based discussions address recognition, diagnosis, and management of infections common in older adults, including those living in long-term care settings: urinary tract infections, upper respiratory tract infections, lower respiratory tract infections, skin and soft tissue infections, and Clostridium difficile infection. The education was implemented at the skilled nursing centers at 15 Veterans Affairs medical centers. Participants from an array of disciplines completed an educational evaluation for each session as well as a pre- and postcourse knowledge assessment.

RESULTS

The number of respondents to the educational evaluation administered following each session ranged from 68 to 108. Learners agreed that each session met its learning objectives (4.80-4.89 on a 5-point Likert scale, 5 = strongly agree) and that they were likely to make changes (2.50-2.89 on a 3-point scale, 3 = highly likely to make changes). The average score on the five-question knowledge assessment increased from 3.6 (72%) to 3.9 (78%, p = .06).

DISCUSSION

By stressing recognition of atypical signs and symptoms of infection in older adults, diagnostic tests, and antibiotic stewardship, this series of five case-based discussions enhanced clinical training of learners from several disciplines.

Herpes Zoster

Primary care providers and hospitalists frequently encounter older or immunocompromised patients with herpes zoster accompanied by debilitating pain. Atypical presentations and zosteriform herpes simplex may present diagnostic challenges to clinicians. This article summarizes the background, evidence, and guidelines for the diagnosis, complications, treatment, and prevention of herpes zoster. Diagnosis of challenging cases relies on polymerase chain reaction as the preferred test. Treatment focuses on optimal use of antiviral therapy and analgesics. Prevention emphasizes utilization of a new recombinant zoster vaccine, which reduces the incidence of herpes zoster by more than 90% and is preferred to the live attenuated herpes zoster vaccine.

A New Community Health Center/Academic Medicine Partnership for Medicaid Cost Control, Powered by the Mega Teaching Health Center

Community health centers (CHCs), a principal source of primary care for over 24 million patients, provide high-quality affordable care for medically underserved and lower-income populations in urban and rural communities. The authors propose that CHCs can assume an important role in the quest for health care reform by serving substantially more Medicaid patients. Major expansion of CHCs, powered by mega teaching health centers (THCs) in partnership with regional academic medical centers (AMCs) or teaching hospitals, could increase Medicaid beneficiaries' access to cost-effective care. The authors propose that this CHC expansion could be instrumental in limiting the added cost of Medicaid expansion via the Affordable Care Act (ACA) or subsequent legislation. Nevertheless, expansion cannot succeed without developing this CHC-AMC partnership both (1) to fuel the currently deficient primary care provider workforce pipeline, which now greatly limits expansion of CHCs; and (2) to provide more CHC-affiliated community outreach sites to enhance access to care. The authors describe the current status of Medicaid and CHCs, plus the evolution and vulnerability of current THCs. They also explain multiple features of a mega THC demonstration project designed to test this new paradigm for Medicaid cost control. The authors contend that the demonstration's potential for success in controlling costs could provide help to preserve the viability of current and future expanded state Medicaid programs, despite a potential ultimate decrease in federal funding over time. Thus, the authors believe that the new AMC-CHC partnership paradigm they propose could potentially facilitate bipartisan support for repairing the ACA.

Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part X: Sacroiliac Joint Syndrome

OBJECTIVE

To present an algorithm of sequential treatment options for managing sacroiliac joint (SIJ) pain in the setting of chronic low back pain (CLBP) in the older adult. This is the tenth part in a series, and includes an illustrative clinical case.

METHODS

The stepped care drug table and evaluation and treatment algorithm were created following a thorough literature review of approaches and subsequent analysis through a modified Delphi process. The principal investigator developed the initial draft, which was refined for content by an interdisciplinary panel of five experts. The refined materials were then assessed for the feasibility of implementation and validity of recommendations for older adults in a primary care setting by a panel of nine primary care providers. While not exclusive to Veteran's Health Administration (VHA) facilities, an emphasis was made to include resources and medications available to providers in the VHA.

RESULTS

The algorithm and drug table developed to systematically identify and address SIJ pain in the older adult is presented here. The process should begin with recognizing the presenting symptoms of CLBP stemming from the SI region, and supporting physical exam testing using the compression test and thigh thrust maneuver. Identification of the SIJ as a pain generator is followed by assessment and treatment of contributory factors. SIJ pain treatment should begin with education and self-management including exercise, and may escalate to include interventional procedures and/or referral to a pain rehabilitation program.

CONCLUSIONS

Pain originating from the SIJ is often under-recognized, but a structured and consistent approach can help identify older patients who would benefit from treatment of this contributor to CLBP.

Aging, the Medical Subspecialties, and Career Development: Where We Were, Where We Are Going

Historically, the medical subspecialties have not focused on the needs of older adults. This has changed with the implementation of initiatives to integrate geriatrics and aging research into the medical and surgical subspecialties and with the establishment of a home for internal medicine specialists within the annual American Geriatrics Society (AGS) meeting. With the support of AGS, other professional societies, philanthropies, and federal agencies, efforts to integrate geriatrics into the medical and surgical subspecialties have focused largely on training the next generation of physicians and researchers. They have engaged several subspecialties, which have followed parallel paths in integrating geriatrics and aging research. As a result of these combined efforts, there has been enormous progress in the integration of geriatrics and aging research into the medical and surgical subspecialties, and topics once considered to be geriatric concerns are becoming mainstream in medicine, but this integration remains a work in progress and will need to adapt to changes associated with healthcare reform.

Compliance With Recommendations From an Outpatient Geriatric Consultation Team

For outpatient geriatric consultation to be effective, it is necessary, although not sufficient, that recommendations made to patients are followed. This prospective cohort study describes the nature of, types of, and compliance with, recommendations made to patients by clinicians at a university-based outpatient geriatric clinic. All patients seen by an internal medicine physician or family practitioner were contacted 1 year following their initial visit to determine compliance with recommendations. Clinicians identified 4.6 problems per patient; more than one half had never been documented previously. The most common problems were medical (53.1%) and neuropsychiatric (26.7%). Pahents had substantial limitations in both instrumental (X = 2.3) and physical (X = 1.3) activities of daily living. Clinicians made 5.9 recommendations per patient, 67.1% of which were followed. Compliance was similar for medical and social recommendations. No predictors of compliance were identified. Practitioners need to be aware that one third of their recommendations are not followed, and characterizing patients at increased risk for noncompliance is difficult.

Herpes Zoster

Herpes zoster causes significant suffering owing to acute and chronic pain or postherpetic neuralgia (PHN). Varicella-zoster virus-induced neuronal destruction and inflammation causes the principal problems of pain, interference with activities of daily living, and reduced quality of life in older adults. The optimal treatment of herpes zoster requires early antiviral therapy and careful pain management. For patients who have PHN, evidence-based pharmacotherapy using topical lidocaine patch, gabapentin, pregabalin, tricyclic antidepressants, or opiates can reduce pain burden. The live attenuated zoster vaccine is effective in reducing pain burden and preventing herpes zoster and PHN in older adults.

Deconstructing chronic low back pain in the older adult--Step by step evidence and expert-based recommendations for evaluation and treatment part III: Fibromyalgia syndrome

OBJECTIVE

To present the third in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. The series presents CLBP as a syndrome, a final common pathway for the expression of multiple contributors rather than a disease localized exclusively to the lumbosacral spine. Each article addresses one of 12 important contributors to pain and disability in older adults with CLBP. This article focuses on fibromyalgia syndrome (FMS).

METHODS

A modified Delphi approach was used to create the evaluation and treatment algorithm, the table discussing the rationale behind each of the algorithm components, and the stepped-care drug recommendations. The team involved in the creation of these materials consisted of a principal investigator, a 5-member content expert panel, and a 9-member primary care panel. The evaluation and treatment recommendations were based on availability of medications and other resources within the Veterans Health Administration (VHA) facilities. However, non-VHA panelists were also involved in the development of these materials, which can be applied to both VA and civilian settings. The illustrative clinical case was taken from the clinical practice of the principal investigator.

RESULTS

Following expert consultations and a review of the literature, we developed an evaluation and treatment algorithm with supporting materials to aid in the care of older adults with CLBP who have concomitant FMS. A case is presented that demonstrates the complexity of pain evaluation and management in older patients with CLBP and concomitant FMS.

CONCLUSIONS

Recognition of FMS as a common contributor to CLBP in older adults and initiating treatment targeting both FMS and CLBP may lead to improved outcomes in pain and disability.

Chronic wound repair and healing in older adults: current status and future research

Older adults are more likely to have chronic wounds than younger people, and the effect of chronic wounds on quality of life is particularly profound in this population. Wound healing slows with age, but the basic biology underlying chronic wounds and the influence of age-associated changes on wound healing are poorly understood. Most studies have used in vitro approaches and various animal models, but observed changes translate poorly to human healing conditions. The effect of age and accompanying multimorbidity on the effectiveness of existing and emerging treatment approaches for chronic wounds is also unknown, and older adults tend to be excluded from randomized clinical trials. Poorly defined outcomes and variables; lack of standardization in data collection; and variations in the definition, measurement, and treatment of wounds also hamper clinical studies. The Association of Specialty Professors, in conjunction with the National Institute on Aging and the Wound Healing Society, held a workshop, summarized in this article, to explore the current state of knowledge and research challenges, engage investigators across disciplines, and identify research questions to guide future study of age-associated changes in chronic wound healing.

Chronic wound repair and healing in older adults: current status and future research

The incidence of chronic wounds is increased among older adults, and the impact of chronic wounds on quality of life is particularly profound in this population. It is well established that wound healing slows with age. However, the basic biology underlying chronic wounds and the influence of age-associated changes on wound healing are poorly understood. Most studies have used in vitro approaches and various animal models, but observed changes translate poorly to human healing conditions. The impact of age and accompanying multi-morbidity on the effectiveness of existing and emerging treatment approaches for chronic wounds is also unknown, and older adults tend to be excluded from randomized clinical trials. Poorly defined outcomes and variables, lack of standardization in data collection, and variations in the definition, measurement, and treatment of wounds also hamper clinical studies. The Association of Specialty Professors, in conjunction with the National Institute on Aging and the Wound Healing Society, held a workshop, summarized in this paper, to explore the current state of knowledge and research challenges, engage investigators across disciplines, and identify key research questions to guide future study of age-associated changes in chronic wound healing.

Circulating CXCR5+PD-1+ response predicts influenza vaccine antibody responses in young adults but not older adults (VAC2P.936)

Although influenza vaccination is recommend for all adults annually, the incidence of vaccine failure, defined as weak or absent increase in neutralizing antibody titers, is increased in the elderly compared to young adults. The T follicular helper subset of CD4+ T cells provide B cell help in germinal centers and are necessary for class-switched antibody responses. Previous studies suggested a role for circulating T follicular helper cells (cTfh) following influenza vaccination in adults, but cTfh have not been studied in elderly adults where weak vaccine responses are often observed. Here, we studied cTfh expressing CXCR5 and Programmed Death 1 (PD-1). cTfh from elderly adults were present at reduced frequency, had decreased in vitro B cell help ability, and greater expression of activation marker inducible costimulator (ICOS) compared to young adults. At seven days after inactivated influenza vaccination, cTfh correlated with influenza vaccine-specific IgM and IgG responses in young adults but not in elderly adults. In sum, we have identified aging-related changes in cTfh which manifested as reduced influenza vaccine responses. Future rational vaccine design efforts should incorporate Tfh measurement as an immune correlate of protection, particularly in the setting of aging.

Transitional Care Partners: a hospital-to-home support for older adults and their caregivers

PURPOSE

To describe the development, implementation, and preliminary results of the Transitional Care (TLC) Partners, a clinical demonstration program that supports the transition from hospital to home of older veterans.

DATA SOURCES

Hospital records of TLC patients to track their hospital and emergency department visits before and after the TLC Partners enrollment. Caregivers of patients completed Preparedness in Caregiving and the Short Form Zarit Burden Scale during the first week of the TLC Partners enrollment and on the week when the services ended.

CONCLUSIONS

The proportion of patients with one or more emergency department visits and rehospitalization is consistently lower among TLC patients compared to non-TLC patients at 30 and 60 days of hospital discharge. The mean preparedness and burden scores before and after the program essentially remained the same.

IMPLICATIONS FOR PRACTICE

The description of the implementation of the TLC Partners offers an example of how nurse practitioner-led interprofessional care models can be adapted to the needs of specific healthcare systems, and how they can be monitored to evaluate their reach, effectiveness, and fidelity to the core components of proved care models.

A randomized, controlled study to assess the effect of silk-like textiles and high-absorbency adult incontinence briefs on pressure ulcer prevention

Pressure ulcer prevention is an important aspect of nursing home care. A 20-week, unblinded, randomized, controlled trial was conducted to compare the rate of nursing home-acquired pressure ulcers and adverse events between residents managed using: 1) a silk-like textile for bedding paired with high-absorbency adult incontinence briefs or 2) usual-care, plain-weave cotton/polyester bed sheets and adult incontinence briefs. All residents with an expected length of stay 30 days or more who agreed to participate were enrolled in the study and assessed daily. A total of 46 residents (all men) was enrolled; 26 (median age 72.7 years, range 54 to 95 years) in the intervention group and 20 (median age 69.5 years, range 51 to 91 years) in the usual care group. At baseline, there were no significant differences in resident demographic variables, including Braden Scale risk scores. Fewer pressure ulcers developed in the intervention (six; average follow up 75.6 days/person) than in the standard care group (20; average follow up 95.6 days/person) (hazard ratio = 0.31, 95% confidence interval 0.12, 0.78) and the number of new non-Stage I ulcers was significantly lower in the intervention group (HR = .23, 95% CI .078, .69, P = 0.0084). The number of adverse events did not differ significantly between the two groups. Additional research is warranted on use of products with the silk-like fabric, alone or in combination with highabsorbencybriefs, in larger groups and different populations.

Predictors of postherpetic neuralgia among patients with herpes zoster: a prospective study

Postherpetic neuralgia (PHN) is the most common complication of herpes zoster (HZ). The main objectives of this study were to: 1) estimate the severity and duration of PHN; and 2) identify the predictors of PHN. From October, 2005 to July, 2006, 261 outpatients with HZ, aged ≥ 50, were recruited within 14 days of rash onset during the routine clinical practice of 83 physicians across Canada. Physicians documented HZ characteristics, treatments, general health, functional, and immune status. HZ pain was measured at recruitment and on days 7, 14, 21, 30, 60, 90, 120, 150, and 180 following recruitment. PHN was defined as a worst pain ≥ 3 persisting or appearing more than 90 days after rash onset. Predictors of PHN were obtained by hierarchical log-binomial regression. Twenty-two percent of 249 immunocompetent subjects with HZ developed PHN. Median duration of PHN was 77 days. Independent predictors of PHN included: older age, limitation in performing usual activities prior to HZ, and pain severity at recruitment. This study confirms that older age and greater acute pain severity are predictors of PHN, while functional status emerges as a novel independent predictor of PHN that deserves further exploration. These findings will contribute to optimal use of the HZ vaccine and testing of new therapies that might prevent PHN.

PERSPECTIVE

This study confirmed that older age and greater acute pain severity are robust predictors of PHN, whereas functional status emerged as a novel predictor. Despite the high proportion of subjects treated with antivirals, the burden of PHN remains considerable, suggesting that prevention and additional early interventions are needed to reduce the burden of HZ.

Health care utilization before and after an outpatient ED visit in older people

BACKGROUND

Older adults in the United States receive a significant amount of care in the emergency department (ED), yet the associations between ED and other types of health care utilization have not been adequately studied in this population.

OBJECTIVES

The goals of this study were to examine the relationships between health care use before and after an ED visit among older adults.

METHODS

This retrospective cohort study examined health care use among 308 patients 65 years or older discharged from a university-affiliated ED. Proportional-hazards models were used to assess the relationship between pre-ED health care use (primary care physician [PCP], specialist, ED, and hospital) and risk of return ED visits.

RESULTS

Older ED patients in this study had visited other types of providers frequently in the previous year (median number of PCP and specialist visits, 4). Patients who used the ED on 2 or more occasions in the previous year were found to have visited their PCP more often than those without frequent ED use (median number of visits, 7.0 vs 4.0; P < .001). Despite more PCP use in this population, frequent ED use was associated with increased risk of a repeat ED visit (hazard ratio, 2.20; 95% confidence interval, 1.15-4.21), in models adjusted for demographics and health status.

CONCLUSION

Older adults who use the ED are also receiving significant amounts of care from other sources; simply providing additional access to care may not improve outcomes for these vulnerable individuals.

Performance of diagnostic tests to detect respiratory viruses in older adults

The performance of 4 laboratory methods for diagnosis of viral respiratory tract infections (RTI) in older adults was evaluated. Seventy-four nasopharyngeal (NP) swab specimens were obtained from 60 patients with RTI at a long-term care facility over 2 respiratory seasons. Sixteen specimens were positive for a respiratory virus by at least 1 method. Multiplex reverse transcriptase polymerase chain reaction (RT-PCR) by the Luminex xTAG Respiratory Viral Panel (RVP) detected 16 (100%) of the positive specimens, RVP of 24-h culture supernatant detected 8 (50%), direct fluorescent antibody testing detected 4 (25%), rapid culture detected 2 (12.5%), and rapid antigen testing detected none. For a comparison group, RVP was performed on NP swabs from 20 outpatient children with RTI. The mean fluorescence intensity by RVP was significantly lower for positive adult patients than pediatric patients (P = 0.0373). Our data suggest that older adult patients shed lower titers of viruses, necessitating a highly sensitive assay such as RT-PCR to reliably detect respiratory viral pathogens.

Respiratory syncytial virus outbreak in a long-term care facility detected using reverse transcriptase polymerase chain reaction: an argument for real-time detection methods

OBJECTIVES: To report an outbreak of respiratory synctyial virus (RSV) in a long‐term care facility (LTCF) during ongoing routine respiratory illness surveillance.

DESIGN: Rapid antigen testing, viral culture, direct fluorescent antibody (DFA) testing, and reverse transcriptase polymerase chain reaction (RT‐PCR) testing for up to 15 viruses in symptomatic residents and chart review.

SETTING: A 120‐bed LTCF.

MEASUREMENTS: Comparison of rapid antigen testing, respiratory viral cultures, and DFA testing and RT‐PCR in residents with symptoms of a respiratory tract infection.

RESULTS: Twenty‐two of 52 residents developed symptoms of a respiratory tract infection between January 29, 2008, and February 26, 2008. RSV was detected using RT‐PCR in seven (32%) of the 22 cases. None of the seven cases had positive RSV rapid antigen testing, and only two had positive culture or DFA results. This outbreak occurred during a time when state wide RSV rates were rapidly declining. One patient was admitted to the hospital during the infection and subsequently died.

CONCLUSION: RSV may cause outbreaks in LTCFs that traditional diagnostic methods do not detect. RT‐PCR can provide a more timely and accurate diagnosis of outbreaks, which allows for early symptomatic treatment, rational use of antibiotics, and improved infection control.

The epidemiological, clinical, and pathological rationale for the herpes zoster vaccine

Worldwide, herpes zoster (HZ) affects millions of patients (particularly older adults) annually and causes significant suffering due to acute and chronic pain, or postherpetic neuralgia (PHN). The objective of this article is to explain the rationale for the HZ vaccine by summarizing data on the epidemiology of HZ in the immunocompetent host, with a focus on recent incidence and risk factor studies; to review information on the burden of HZ; and to discuss the challenges of lessening the morbidity of the disease. The incidence and severity of HZ and PHN are highest in older adults. Given the central nervous system damage caused by HZ, the difficulty of adequately treating HZ to prevent PHN, and the intractability of PHN, the advent of the HZ vaccine appears to be a crucial innovation for preventing HZ and PHN.

Herpes zoster and postherpetic neuralgia in older adults

Herpes zoster (HZ) afflicts millions of older adults annually and causes significant suffering from acute and chronic pain, or postherpetic neuralgia (PHN). HZ is caused by the reactivation of varicella-zoster virus (VZV) in sensory ganglia in the setting of age, disease, and drug-related decline in cellular immunity. VZV-induced neuronal destruction and inflammation cause the pain, interference with activities of daily living, and reduced quality of life. The optimal treatment of HZ requires early antiviral therapy and pain management. For PHN, evidence-based pharmacotherapy can reduce pain burden. The zoster vaccine is effective in reducing pain burden and preventing HZ and PHN in older adults.

Prevention strategies: herpes zoster, post-herpetic neuralgia and immunogenicity

Herpes zoster is a common condition that can have a significant impact on quality of life among older adults. A significant proportion of older subjects with herpes zoster develop post-herpetic neuralgia (PHN), a chronic condition that is difficult to treat. The Shingles Prevention Study was a large-scale clinical trial to determine the efficacy of a live, attenuated varicella zoster virus (VZV) vaccine ('zoster vaccine') for preventing or attenuating herpes zoster in subjects aged > or =60 years. A total of 38 546 subjects were given either zoster vaccine or placebo. The burden of illness (pain severity-by-duration), incidence of herpes zoster, and PHN decreased by 61.1%, 51.3% and 66.5% (all P<0.001), respectively, following vaccination. Vaccine efficacy was maintained for a 4-year follow-up period. A sub-study of the vaccine trial evaluated VZV-specific immunity in approximately 1200 vaccine or placebo recipients prior to vaccination, at 3 months and annually for 3 years. VZV-specific cell-mediated immunity (CMI) was boosted significantly by the zoster vaccine. This boost remained substantially intact for the 3 years of follow-up. It is likely that the vaccine-induced boost in VZV-specific CMI reversed the natural decline in these responses that occurs as part of the ageing process, thereby protecting vaccine recipients against herpes zoster and its complications.

Surgical site infection in the elderly following orthopaedic surgery. Risk factors and outcomes

BACKGROUND

Risk factor and outcomes data pertaining to surgical site infection in the elderly following orthopaedic operations are lacking. The aim of this study was to identify risk factors for surgical site infections and to quantify the impact of these infections on health outcomes in elderly patients following orthopaedic surgery.

METHODS

A risk factor and outcomes study was performed at Duke University Medical Center, a tertiary care center, and seven community hospitals in North Carolina and Virginia between 1991 and 2002. The study included elderly patients in whom a surgical site infection had developed following orthopaedic surgery and elderly patients in whom a surgical site infection had not developed following orthopaedic surgery (controls). Outcome measures included mortality during the one-year postoperative period and the total length of the hospital stay (including readmissions during the ninety-day postoperative period).

RESULTS

One hundred and sixty-nine patients with a surgical site infection were identified, and 171 controls were selected. The mean age of the patients was 74.7 years. The most frequent procedures were hip arthroplasty (n = 74, 22%) and open reduction of fractures (n = 55, 16%). The most common pathogen was Staphylococcus aureus (n = 95, 56%). A risk factor for surgical site infection, identified in the multivariate analysis, was admission from a health-care facility (odds ratio = 4.35; 95% confidence interval = 1.64, 11.11). Multivariate analysis also indicated that surgical site infection was a strong predictor of mortality (odds ratio = 3.80; 95% confidence interval = 1.49, 9.70) and an increased length of stay in the hospital (multiplicative effect = 2.49; 95% confidence interval = 2.10, 2.94; 9.31 mean attributable days per infection, 95% confidence interval = 6.88, 12.13).

CONCLUSIONS

Measures for prevention of surgical site infection in elderly patients should target individuals who reside in health-care facilities prior to surgery. Future studies should be done to examine the effectiveness of such interventions in preventing infection and improving outcomes in elderly patients who undergo orthopaedic surgery.

Development of a measure of the burden of pain due to herpes zoster and postherpetic neuralgia for prevention trials: adaptation of the brief pain inventory

In preparation for clinical trials of a vaccine against herpes zoster (HZ), we conducted a prospective, observational study to evaluate (1) the Zoster Brief Pain Inventory (ZBPI), an HZ-specific questionnaire to quantify HZ pain and discomfort, (2) an operational definition of postherpetic neuralgia (PHN), and (3) a severity-duration measure of the burden of illness caused by HZ. HZ patients aged 60 years or older (n = 121) were enrolled within 14 days of rash onset and completed ZBPI, McGill Pain Questionnaire Present Pain Intensity (PPI), quality of life (QoL), and activities of daily living (ADL) questionnaires on a predetermined schedule. Reliability, measured by intraclass correlation coefficients within 14 days of rash onset, ranged between 0.63 and 0.78. ZBPI pain scores were strongly correlated with other pain measures, interference with ADL, and worsening QoL. The operational definition of PHN, a ZBPI pain score of 3 or greater occurring 90 or more days after rash onset, had high agreement with pain worse than mild on the PPI (kappa = 0.72). The ZBPI pain severity-duration measure had high correlations with severity-duration measures of ADL interference, worsening QoL, and other pain scales. These findings support the validity and utility of the ZBPI, the definition of PHN, and the severity-duration measure of the burden of HZ illness.

PERSPECTIVE

Herpes zoster pain, as measured by the ZBPI severity-duration measure, is associated with impairment in daily living activities and quality of life. The ZBPI measure appears useful for quantifying herpes zoster pain, postherpetic neuralgia, and impairment in daily living activities for clinical trials of herpes zoster prevention.
