A palliative nursing strategy to enhance communication and support for patients and families in intensive care units.

AIM: There have been significant advancements in palliative nursing in health services, but less so in intensive care units (ICUs). The purpose of this literature review was to examine palliative nursing care in ICUs and consider how a nursing strategy could improve communication and support for patients and their families. METHOD: An exploratory literature review was conducted to evaluate and compare ICU care strategies with palliative support. The search was conducted using CINAHL Plus and Medline All databases and was limited to a 6-year period. Eight publications were selected for review and a full text review was undertaken using the Critical Appraisal Skills Programme systematic review checklist. RESULTS: Two themes emerged around the use of palliative nursing strategies. These were: improving communication between health professionals and patients; and providing support for patients and families. CONCLUSIONS: Palliative nursing has the potential to improve the quality of communication in ICU settings and support for patients and families. Further training and preparation of nurses in palliative care would improve the patient and family experience during a critical and emotional period of health service provision.

Inter- and Intra-rater Reliability of the Hart-ISSG Proximal Junctional Failure Severity Scale.

STUDY DESIGN: Reliability/external validation study. OBJECTIVE: Investigate inter- and intrarater reliability of the Hart-International Spine Study Group (ISSG) Proximal Junctional Failure Severity Scale (PJFSS) and its correlation with operative revision in patients with proximal junctional failure (PJF). SUMMARY OF BACKGROUND DATA: The Hart-ISSG PJFSS is a validated classification system for PJF. Reliability of the PJFSS has not been assessed. METHODS: Sixteen detailed clinical scenarios were assessed using the ISSG PJFSS classification in six categories: neurologic status, axial pain, instrumentation issue, proximal kyphotic angle, level of upper instrumented vertebrae (UIV), and severity of UIV/UIV+1 fracture. Eleven spine surgeons evaluated each case in all six categories during two different assessments, and provided recommendations regarding operative revision or observation for each case. Inter- and intrarater reliability were calculated based on intraclass correlation coefficients. RESULTS: All intraclass correlation coefficients demonstrated "almost perfect"' (0.817-0.988) inter-rater agreement for both assessments, except UIV/UIV+1 fracture severity during the second assessment, which demonstrated "substantial" agreement' (0.692). Five of six categories had "almost perfect" mean intrarater reliability (0.805-0.981), while "instrumentation issue" demonstrated "substantial" mean agreement (0.757). Inter-rater reliability for recommendation of surgical intervention was "almost perfect" during both assessments (0.911 and 0.922, respectively). Mean PJFSS scores between the two assessments were significantly higher for cases recommended for operative revision (8.43 ±â€Š0.90) versus cases recommended for observation (P < 0.0001). CONCLUSION: The ISSG PJFSS is a reliable and repeatable classification system for assessing patients with PJF. Higher PJFSS scales correlate with recommendation for operative revision, extending prior external validation of the PJFSS. LEVEL OF EVIDENCE: 3.

Proximal Junctional Kyphosis: Inter- and Intraobserver Reliability of Radiographic Measurements in Adult Spinal Deformity.

STUDY DESIGN: Reliability study of radiographic measures of proximal junctional kyphosis (PJK) in patients with adult spinal deformity (ASD). OBJECTIVE: To assess impacts of level of proximal endpoint and vertebral fracture on reliability of measurement of junctional kyphosis. SUMMARY OF BACKGROUND DATA: Radiographic assessment is important in determining management of patients with PJK or proximal junctional failure (PJF). No study to date has evaluated the reliability of radiographic measurement of the junctional kyphotic angle after surgery for ASD. METHODS: Postoperative radiographs from 52 patients with ASD were divided into four categories based on the level of the upper instrumented vertebra (UIV) and the presence or absence of PJF: upper thoracic without failure (UT), thoracolumbar without failure (TL), upper thoracic with PJF (UTF), and thoracolumbar with PJF (TLF). Nine surgeon reviewers performed radiographic measurements of kyphosis between UIV+2 and UIV twice at least 4 weeks apart. Intraclass correlation coefficients (ICC) were calculated to determine inter- and intraobserver reliability. RESULTS: Interobserver reliability for measurements of UT, TL, UTF, and TLF were all "almost perfect" with ICC scores of 0.917, 0.965, 0.956, and 0.882, and 0.932, 0.975, 0958, and 0.989, for sessions 1 and 2, respectively. Similarly, ICCs for kyphosis measurements for the TL and TLF group had "almost perfect" agreement with means of 0.898 (range: 0.817-0.969) and 0.976 (range: 0.931-0.995), respectively. ICCs for measurements for the UT and UTF groups all had "substantial" or "almost perfect" agreement with means of 0.801 (range: 0.662-0.942) and 0.879 (range: 0.760-0.988), respectively. CONCLUSION: The present study demonstrates high inter- and intraobserver reliability of PJK measurement following instrumented fusion for ASD, independent of the presence or absence of PJF. Although slightly lower for upper thoracic than for thoracolumbar proximal endpoints, all ICCs consistently reached at least "substantial agreement" and "near perfect agreement" for most.

Rehabilitation and Postoperative Management Practices After Osteochondral Allograft Transplants to the Distal Femur: A Report From the Metrics of Osteochondral Allografts (MOCA) Study Group 2016 Survey.

CONTEXT: We present the current spectrum of postoperative management practices for patients receiving distal femur osteochondral allograft (OCA) transplants. EVIDENCE ACQUISITION: The Joint Restoration Foundation database was examined in cooperation with the Metrics of Osteochondral Allografts study group to identify 121 surgeons who had performed at least 1 OCA transplant in the past year; 63% of surgeons responded. STUDY DESIGN: Clinical survey. LEVEL OF EVIDENCE: Level 3. RESULTS: Postoperative weightbearing restrictions ranged from immediate nonweightbearing with full weightbearing by 12 weeks to immediate weightbearing as tolerated. Most surgeons who performed fewer (<10) OCA transplants per year followed the most restrictive protocol, while surgeons who performed more (>20) OCA transplants per year followed the least restrictive protocol. One-third of surgeons with the most restrictive protocol were more likely to change their protocol to be less restrictive over time, while none of those with the least restrictive protocol changed their protocol over time. Fifty-five percent of surgeons permitted return to full activity at 26 weeks, while 27% of surgeons lifted restrictions at 16 weeks. CONCLUSION: Characterization of the spectrum of postoperative management practices after OCA transplantation provides a foundation for future investigations regarding patient outcomes and associated cost to establish best practice guidelines. Fundamentally, surgeons with more experience with this procedure tended to be more aggressive with their postoperative rehabilitation guidelines. Most commonly, rehabilitation provided for some degree of limited weightbearing; however, the spectrum also included immediate full weightbearing practices.

Magnetic Resonance Imaging Characterization and Clinical Outcomes After NeoCart Surgical Therapy as a Primary Reparative Treatment for Knee Cartilage Injuries.

BACKGROUND: Autologous cartilage tissue implants, including the NeoCart implant, are intended to repair focal articular cartilage lesions. Short-term results from United States Food and Drug Administration (FDA) phase I and phase II clinical trials indicated that the NeoCart implant was safe when surgically applied as a cell-based therapy and efficacious compared with microfracture. HYPOTHESIS: Quantitative magnetic resonance imaging (MRI) analysis would reveal NeoCart tissue maturation through to 60-month follow-up. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients with symptomatic full-thickness cartilage lesions of the distal femoral condyle were treated with NeoCart in FDA clinical trials. Safety and efficacy were evaluated prospectively by MRI and clinical patient-reported outcomes (PROs) through to 60-month follow-up. Qualitative MRI metrics were quantified according to modified MOCART (magnetic resonance observation of cartilage repair tissue) criteria, with an independent evaluation of repair tissue signal intensity. Subjective PROs and objective range of motion (ROM) were obtained at baseline and through to 60 months. RESULTS: Twenty-nine patients treated with NeoCart were observed over a mean of 52.0 ± 15.5 months (median, 60 months). MOCART analyses indicated significant improvement ( P < .001) in cartilage quality from 3 to 24 months, with stabilization from 24 to 60 months. Signal intensity of the repair tissue evolved from hyperintense at early follow-up to isointense after 6 months and to hypointense after 24 months. The temporal progression toward hypointense T2 signals at later time points observed here indicated a further reorganization of the repair tissue toward a dense tissue that was less similar to the surrounding native tissue. However, 80% of patients showed evidence of subchondral bone changes on MRI at all time points; 4 patients (14%) showed no improvement of MRI criteria. Compared with baseline values, significant improvement ( P < .001) was seen in PROs (mean [±SD] baseline to mean [±SD] final follow-up), including the International Knee Documentation Committee score (47.9 ± 17.4 to 75.5 ± 22.1), physical component summary of the Short Form-36 (40.5 ± 7.2 to 51.4 ± 8.1), and all 5 domains of the Knee injury and Osteoarthritis Outcome Score (Pain: 64.8 ± 12.1 to 86.1 ± 17.3; Activities of Daily Living: 75.5 ± 14.8 to 91.6 ± 13.8; Quality of Life: 28.6 ± 15.5 to 69.4 ± 28.0; Symptoms: 65.8 ± 13.8 to 86.6 ± 13.4; Sports and Recreation: 41.4 ± 24.3 to 72.4 ± 28.8). Significant ( P < .0001) decreases from baseline scores for the visual analog scale for pain (34.6 ± 22.5) were seen by 6 months and sustained at final follow-up (14.3 ± 18.4). ROM significantly ( P < .0001) improved from baseline (131.5° ± 7.9°) to final follow-up (140.7° ± 6.3°). CONCLUSION: Longitudinal MRI analysis demonstrated that NeoCart-based repair tissue is durable and evolves over time. For a majority of patients, this progression trended from an initial hyperintense signal to a hypointense signal at later follow-ups. Changes in radiographic measures over time corresponded with improvement in clinical measures, with maximum benefits experienced at 24-month follow-up. Similarly, clinical efficacy for the total cohort, determined by clinical outcome scores, reached a maximum at 24 months without decline to 60 months. Results from safety and exploratory clinical trials indicate that NeoCart is a safe and effective treatment for articular cartilage lesions through to 5-year follow-up. Registration: NCT00548119 ( ClinicalTrials.gov identifier).

Stiffness After Pan-Lumbar Arthrodesis for Adult Spinal Deformity Does Not Significantly Impact Patient Functional Status or Satisfaction Irrespective of Proximal Endpoint.

STUDY DESIGN: Prospective, multicenter. OBJECTIVE: To determine if stiffness significantly affects function or satisfaction after pan-lumbar arthrodesis. SUMMARY OF BACKGROUND DATA: The Lumbar Stiffness Disability Index (LSDI) is a validated measure of the effect of lumbar stiffness on functional activities. Data suggests that patients undergoing fusion of the entire lumbar spine are at greatest risk of functional limitations from stiffness. METHODS: The LSDI, Short Form 36, Scoliosis Research Society-22, and Oswestry Disability Index were administered preoperatively and at 2-year minimum follow-up to 103 spinal deformity patients from 11 centers. Patients were separated according to the proximal arthrodesis level; upper thoracic (T2-5) to pelvis (UT-Pelvis) or thoraco-lumbar (T10-T12) to pelvis (TL-Pelvis). Outcome scores were compared using Student t test or Tukey-Kramer Honest Significant Difference Analysis of Variance. Regression analysis of final LSDI scores versus Scoliosis Research Society-22 Satisfaction scores was performed. RESULTS: Mean ages, baseline values, and final scores of all outcome parameters were statistically equivalent in the two groups. Final LSDI scores did not change significantly from baseline in the UT-Pelvis (P = 0.478) or TL-Pelvis (P = 0.301) groups. In contrast, highly significant improvements (P ≤ 0.0001) from baseline were seen in both groups for other health-related QoL measures. The 2-year Satisfaction scores were statistically equivalent in the two groups, and the correlation between final LSDI and Satisfaction scores in the entire cohort was not significant (R = 0.013, P = 0.146). CONCLUSION: Patients undergoing pan-lumbar arthrodesis for adult spinal deformity did not experience substantial increases in disability due to stiffness of the low back, although they did report significant improvements in other health-related QoL measures. Further, LSDI scores did not correlate with patient satisfaction. There were no significant differences in perceived stiffness effects whether arthrodesis stopped in the thoracolumbar or upper thoracic regions. We hope these results will be useful to spine surgeons and patients during preoperative planning and discussions. LEVEL OF EVIDENCE: 2.

Functional limitations due to stiffness as a collateral impact of instrumented arthrodesis of the lumbar spine.

STUDY DESIGN: Prospective cohort study. OBJECTIVE: To understand whether patients actually perceive increased limitations as compared with their preoperative state due to stiffness after lumbar arthrodesis. SUMMARY OF BACKGROUND DATA: Lumbar arthrodesis by intention eliminates spinal motion in an attempt to decrease pain, deformity, and instability. Independent of pain, loss of mobility can impact ability to perform certain activities of daily living. The lumbar stiffness disability index (LSDI) is a validated measure of the effect of lumbar stiffness on functional activities. To date, no prospective evaluations of stiffness impacts on patient function after lumbar arthrodesis have been reported. METHODS: The LSDI, 36-Item Short Form Health Survey, and Oswestry Disability Index were administered preoperatively and at 2-year minimum follow-up to 62 adult patients undergoing lumbar fusion for degenerative disease or spinal deformity. Patients also completed a satisfaction questionnaire at 2 years. Patients were separated according to the number of lumbar arthrodesis levels. Pre- and postoperative LSDI, 36-Item Short Form Health Survey physical composite score, and Oswestry Disability Index scores were compared using paired t tests. RESULTS: Significant improvements in Oswestry Disability Index were observed across all arthrodesis levels, and significant improvements in physical composite score were observed at level 1 and at 5 or more levels. Patients undergoing 1-level arthrodesis demonstrated statistically significant decreases in LSDI scores, indicating less impact from stiffness than at baseline. Patients with 3 or 4 levels and 5 or more levels of arthrodesis showed increases in LSDI scores, although none reached significance with the numbers available. Forty-six percent of patients reported that low back stiffness created significant limitations in activities of daily living, although 97% indicated that they would undergo the same procedure again and 91% reported that any increase in stiffness was an acceptable trade-off for their functional improvements from lumbar arthrodesis. CONCLUSION: Patients undergoing elective lumbar arthrodesis reported relatively limited functional deficit due to stiffness at 2-year follow-up. Paradoxically, patients undergoing 1-level arthrodesis actually reported significantly less limitation due to stiffness postoperatively. Although the effects of stiffness did trend toward greater impacts among patients undergoing longer fusions, 91% of patients were satisfied with trade-offs of function and pain relief in exchange for perceived increases in lumbar stiffness.

Reduction of airway complications with fluid management protocol in patients undergoing cervical decompression and fusion across the cervicothoracic junction.

STUDY DESIGN: Retrospective comparative cohort analysis. OBJECTIVE: To evaluate the effect of an intraoperative and intensive care unit protocol on incidence of airway complications for patients undergoing combined anterior-posterior cervical decompression and fusion crossing the cervicothoracic junction (CTAPF). SUMMARY OF BACKGROUND DATA: Airway compromise remains an important potential complication for patients undergoing CTAPF. Volume of intravenous fluid replacement perioperatively has been correlated with risk of airway complications in this patient population. METHODS: A retrospective cohort study was performed comparing airway complications (postoperative airway edema requiring reintubation and/or prolonged need for intubation) in patients undergoing CTAPF prior to and after introduction of a standardized protocol. The protocol required limitation of crystalloid fluid resuscitation intraoperatively, with maintenance of blood pressure using vasopressors. Comparisons between the 2 cohorts included operative time, intraoperative blood loss, volume of IV fluid replacement, and incidence of airway complications and dysphagia. RESULTS: Among patients operated prior to establishment of the protocol, 45% (9/20) experienced airway edema requiring extended intubation or reintubation. This rate was reduced to zero among 8 patients operated after the adoption of the protocol (P = 0.029). Intraoperative IV fluid volumes were reduced from 6190 mL to 4802 mL after institution of the protocol (P = 0.016). EBL and total surgical time did not differ between the 2 cohorts (1024 mL vs. 869 mL, P = 0.443; and 6.76 hr vs. 7.18 hr, P = 0.460). Incidence of dysphagia was not significantly different between the 2 cohorts. CONCLUSION: Establishment of a fluid and airway management protocol for patients undergoing CTAPF reduced the incidence of prolonged intubation or reintubation. Given the potentially life-threatening impact of loss of airway patency, intraoperative restriction of IV fluid while maintaining adequate blood pressure may be helpful in increasing the safety of surgical intervention in this complex patient population.

Post-traumatic stress symptoms after elective lumbar arthrodesis are associated with reduced clinical benefit.

STUDY DESIGN: Prospective cohort study. OBJECTIVE: To assess the impact of postoperative post-traumatic stress disorder (PTSD) symptoms on clinical outcomes after lumbar arthrodesis. SUMMARY OF BACKGROUND DATA: Postoperative PTSD symptoms occur among many patients who underwent elective lumbar fusion. Although adverse impact of preoperative depression and psychiatric distress has been described, no reports have assessed the impact of postoperative PTSD symptoms on clinical outcomes after lumbar arthrodesis. METHODS: Seventy-three patients undergoing elective lumbar spinal arthrodesis completed the PTSD Checklist-Civilian Version (PCL-C) at 3, 6, 9, and 12 months postoperatively. Short-Form 36 and the Oswestry Disability Index (ODI) were completed preoperatively and at 1 year postoperatively. Impact of postoperative PTSD symptoms, preoperative psychiatric diagnoses, and mental composite scores on clinical outcome scores and likelihood of reaching minimal clinically important difference for ODI and physical composite score (PCS) was evaluated. RESULTS: PTSD symptoms were reported in 22% of the cohort, with significantly reduced surgical benefit as measured by final (P < 0.0001 and P = 0.003) and total change (P = 0.013 and P = 0.032) in ODI and PCS scores, respectively. Likelihood of reaching minimal clinically important difference for both ODI and PCS was also reduced for patients reporting PTSD symptoms (P = 0.009 and P = 0.001, respectively). A preoperative psychiatric diagnosis correlated only with final ODI score (P = 0.008). Preoperative mental composite scores were significantly correlated with final ODI and PCS scores, as well as final change from preoperative and likelihood of reaching minimal clinically important difference for PCS, but not for ODI scores. CONCLUSION: Postoperative psychological distress was strongly correlated with reduced clinical benefit among patients who underwent elective lumbar arthrodesis, and seemed to be a stronger predictor of reduced clinical benefit than either major psychiatric diagnosis or preoperative mental composite scores. Efforts to reduce postoperative psychological distress may offer an opportunity to enhance patient reported clinical outcomes from elective spine surgery. LEVEL OF EVIDENCE: 2.

Depression and cigarette smoking independently relate to reduced health-related quality of life among Canadians living with hepatitis C.

BACKGROUND: Many people living with chronic viral hepatitis C (HCV) report reduced health-related quality of life. The relative contribution of behavioural, psychosocial and HCV disease factors to reduction in HCV health-related quality of life is not well understood. The objectives of the present study were to compare standardized health-related quality of life scores between Canadian HCV patients and age-matched Canadian and American norms, and to examine the relative contribution of biopsychosocial variables (ie, cigarette smoking, alcohol intake and depression) to health-related quality of life scores among Canadian HCV patients. METHODS: HCV RNA-positive patients were recruited during their first visit to the Ottawa Hospital Viral Hepatitis Clinic (Ottawa, Ontario). A questionnaire assessing health behaviours, health-related quality of life and depressed mood was completed. Data on liver studies, liver biopsy findings and HIV serostatus were also collected. RESULTS: A total of 123 participants (71% men) ranging from 20 to 67 years of age were evaluated. All had compensated liver function. Patients reported significantly lower health-related quality of life compared with age-matched Canadian and American normative samples. In a series of hierarchical multiple regression models, depression and smoking were independently related to compromised health-related quality of life scores, even after controlling for sociodemographic variables and health behaviours. DISCUSSION: These results highlight the value of adopting a biopsychosocial model of HCV care. Depressed mood and smoking behaviour should be evaluated in HCV patients. Empirically validated psychological and pharmacological treatments for depression and smoking cessation may improve health-related quality of life in HCV infected patients.

Evaluation of health care needs and patient satisfaction among hepatitis C patients treated at a hospital-based, viral hepatitis clinic.

OBJECTIVE: To define self-reported hepatitis C knowledge, health care needs, and patient satisfaction in a representative cohort of hepatitis C virus (HCV)-infected adults treated at a university hospital-based viral hepatitis clinic in Canada. METHODS: A questionnaire package evaluating HCV knowledge, health care needs, and patient satisfaction was administered to 111 consecutive consenting HCV patients during their first and 10-month follow-up HCV clinic visits. RESULTS: At their first HCV clinic visit, 52% of patients rated their current HCV knowledge as "fair" or "poor". Patients identified HCV education, quality medical care, medication coverage, and psychological counselling as important HCV health care needs. Health care satisfaction outcome data at 10-month follow-up indicated that patients felt significantly better informed, more satisfied, and more actively involved in their HCV health care. CONCLUSION: A bio-psychosocial framework in which medical, psychological, educational, and social issues are addressed is desirable for optimal HCV health care.
