Nutritional status of cancer patients and its relationship to function in an inpatient rehabilitation setting

Relationship Between Cachexia and the Functional Progress of Patients With Cancer in Inpatient Rehabilitation

PURPOSE

Although inpatient rehabilitation can improve functional independence in patients with cancer, the role of cachexia in this population is unknown. Our objectives were to:1) Establish prevalence of cachexia in a cohort of cancer patients receiving inpatient rehabilitation and its association with demographic and oncological history.2) Determine the relationship between the presence of cachexia and functional recovery and whether these patients in inpatient rehabilitation have a distinct prognosis.

METHODS

This is a retrospective cohort study of 250 patients over 330 admissions to an inpatient rehabilitation facility. Body weight loss threshold and Weight Loss Grading Scale identified patients with and without cachexia. Main outcomes were functional independence measure scores, discharge destination, and 6-mo survival.

RESULTS

Prevalence of cachexia in inpatient rehabilitation was 59% using consensus body weight loss criteria, and 77% of cancer patients had a Weight Loss Grading Scale score greater than 0. Patients with and without cachexia had similar motor and cognitive gains, although patients with severe cachexia had more limited functional gains ( P < 0.05) and increased odds of acute care return ( P < 0.01). Patients with a Weight Loss Grading Scale score of 4 had decreased survival at 6 mos ( P < 0.05) compared with noncachectic patients.

CONCLUSIONS

These data suggest that there is a relationship between cachexia and recovery for cancer patients that should be further studied in rehabilitation settings.

Azotemia in Cancer Patients During Inpatient Rehabilitation

This paper presents a study of the relationship between prerenal azotemia and rehabilitation outcomes of cancer patients. A retrospective chart review of 70 patients who underwent inpatient rehabilitation in a tertiary cancer center was undertaken. Eight patients with creatinine values >1.5 were excluded. The remaining 62 patients were divided into 2 groups according to the blood urea nitrogen/creatinine (BUN/Cr) ratio: 27 (44%) in the prerenal azotemia group (BUN/Cr ≥ 20) and 35 (56%) in the non-azotemic group (BUN/Cr < 20). Age, gender, <10 g/dL of hemoglobin, co-morbidity (diabetes mellitus and/or hypertension), discharge destiny and median rehabilitation length of stay were not significantly different in these 2 groups. Prerenal azotemia was present in a significant number of cancer patients, but it did not impact the length of rehabilitation stay or discharge destiny.

The Prognostic Value of High-sensitivity C-reactive Protein and Prealbumin for Short-term Mortality in Acutely Hospitalized Multimorbid Elderly Patients: A Prospective Cohort Study

OBJECTIVES

To establish the predictive value on mortality after 2 months from hospital admission of two laboratory markers of nutritional and inflammatory status, high-sensitivity C-reactive protein (hs-CRP) and prealbumin, in a cohort of frail multimorbid elderly without terminal illness.

DESIGN

Prospective cohort study.

SETTING

Internal medicine ward of a large teaching hospital in Italy.

PARTICIPANTS

544 Caucasian patients with acute disease consecutively admitted from January to June 2013. 102 were excluded for being younger than 65 years old, having life expectancy <30 days or not having frailty syndrome. Further 42 patients were excluded for missing data or withdrawn at follow-up. Final analysis was performed on 400 subjects (179 M, 221 F, mean age 79±10).

MEASUREMENTS

Serum prealbumin and hs-CRP were measured at admission. Death within 2 months from hospital admission was assessed through a telephonic interview with the caregiver for each patient discharged alive. Inhospital mortality was also recorded. Survival was calculated from date of admission to our unit.

RESULTS

Mean prealbumin at admission was 17.3±7.7 mg/dl, while hs-CRP median was 24.2 mg/L (IQR 8.7 to 51.8). 108 patients (27%) died within two months from admission. In an age- and sex-adjusted analysis, log(hs-CRP) levels at admission, but not prealbumin, were independently associated with an increased risk for mortality (HR 1.40, 95% CI 1.18 to 1.66, p<0.001). After multiple adjustments for covariates, including comorbidity burden measured through Charlson score, log(hs-CRP) remained significantly associated with mortality (HR 1.38, 95% CI 1.08 to 1.76, p=0.01). A Receiver Operating Characteristic (ROC) curve was performed to test the predictive value of hs-CRP at admission on two-month mortality (AUC 0.68, 95% CI 0.63 to 0.72, p<0.001). Cut-off value was set at 38.4 mg/L. After dichotomization of hs-CRP values according to this cut-off, hs-CRP≥38.4 mg/L at admission proved to be a significant risk factor for mortality (HR 2.10, 95% CI 1.23 to 3.58, p=0.006).

CONCLUSION

Serum hs-CRP, but not prealbumin, values at admission are predictors of short-term mortality at hospital admission in elderly multimorbid patients. Inflammation seems to affect prognosis more than malnutrition in this setting and may therefore guide clinicians' attitude towards therapeutic choices.

Preoperative nutritional assessment and prognosis in patients with foregut tumors

Malnourished patients with gastrointestinal tumours are at risk for postoperative complications and death. The aim of this study was to determine which nutritional assessment method better predicts outcome. Seventy-four patients, 45 men and 29 women; mean (SD) age of 63 (102) yr (range = 34 to 83), undergoing surgical resections for esophageal (n = 19) gastric (n = 43) and pancreatic (n = 12) tumors were preoperatively assessed by Patient Generated Subjective Global Assessment, anthropometry, and by laboratory sampling. Forty-three (58%) of them were unnourished; 25 Subjective Global Assessment (SGA)-A, 34 SGA-B, and 15 SGA-C cases. Mean (SD) of dominant hand adductor pollicis muscle thickness (DAPM) was 13 (3.5) mm and mean (SD) serum albumin was 3.8 (0.5) g/dL. Mean (SD) hospital staying for patients who complicated and died was 34 (29) days and 23 (13) days for survivors (not significant); SGA-B cases were significantly associated with higher mortality (n = 12, P<0.001). Patients with a mean (SD) DAPM below 10.8 (3.7) mm died more frequently than those with a mean (SD) greater than 14 (3) mm (P < 0.001). None of the methods was significantly related to hospital stay, but receiver operating characteristic curves (95% confidence interval) for PG-SGA and DAPM thickness (0.75 and 0.74) reliably predicted mortality (P<0.001) and these methods may be used as preoperative parameter.

Inpatient rehabilitation improved functional status in asthenic patients with solid and hematologic malignancies

OBJECTIVE

The aim of this study was to compare functional outcomes in asthenic patients with hematologic malignancies with those of asthenic patients with solid tumors after inpatient rehabilitation. We hypothesized that asthenic patients with hematologic malignancies are less likely than patients with solid tumors to make functional improvement after rehabilitation.

DESIGN

The records of 60 asthenic cancer patients (30 consecutive patients with solid tumors and 30 consecutive patients with hematologic malignancies) who underwent inpatient rehabilitation at a comprehensive cancer center between October 2005 and October 2007 were retrospectively reviewed. Patients with focal neurologic deficits were excluded. All patients admitted to the inpatient rehabilitation unit received 3 hrs of more of therapy per weekday. The main outcomes included total, motor, and cognitive Functional Independence Measure (FIM) scores, hospital and rehabilitation length of stay, and FIM efficiency.

RESULTS

The mean total FIM score significantly improved in patients with solid tumors (mean, 15; range, -6 to 38) and in patients with hematologic malignancies (mean, 17; range, -3 to 27); however, between-group differences in FIM scores were not significant (P = 0.31). The solid tumor patients were significantly older than the hematologic malignancy patients (71 ± 11 vs. 64 ± 12 yrs; P = 0.02), but the mean rehabilitation lengths of stay were the same for each group (9.5 days; P = 0.82). The mean FIM efficiency in the hematologic malignancy group was higher than that of the solid tumor group (1.9 vs.1.4; P = 0.049).

CONCLUSIONS

Asthenic patients with solid tumors or hematologic malignancies could benefit from inpatient rehabilitation and make significant functional gain.

Comparison of postoperative rehabilitation in cancer patients undergoing internal and external hemipelvectomy

OBJECTIVE

To compare postoperative rehabilitation, functional outcome, and pain management in cancer patients who underwent an internal hemipelvectomy versus an external hemipelvectomy.

DESIGN

Retrospective study.

SETTING

Tertiary cancer center.

PARTICIPANTS

Patients (N=60) who underwent a hemipelvectomy between February 1996 and November 2005 were included in this study (30 internal hemipelvectomy patients and 30 external hemipelvectomy patients).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Hospital and rehabilitation length of stay (LOS), percentage of physiatrist consultation and inpatient rehabilitation, functional status of transfers and ambulation, and pain medication utilization.

RESULTS

The rate of physiatrist consultation and acute rehabilitation admission were 15 (50%) of 30 and 13 (43%) of 30 for internal hemipelvectomy patients, and 16 (53%) of 30 and 16 (53%) of 30 for external hemipelvectomy patients. Median hospital LOS for external hemipelvectomy patients (37d) was significantly longer than for internal hemipelvectomy patients (19d) (P=0.004); median rehabilitation LOS was similar in both groups (20d for external hemipelvectomy patients versus 22 for internal hemipelvectomy patients; P=0.83). On discharge, 14 (47%) of 30 internal hemipelvectomy patients could ambulate without assistance, whereas only 5 (17%) of 30 external hemipelvectomy patients could do so (P=0.013). The median morphine equivalent daily dose at discharge for external hemipelvectomy patients (150mg) was significantly higher than that for internal hemipelvectomy patients (45mg) (P=0.032).

CONCLUSIONS

A similar percentage of internal hemipelvectomy and external hemipelvectomy patients were admitted to inpatient rehabilitation. External hemipelvectomy patients had longer hospital LOS, less favorable functional outcome, and required more intense treatment for pain.

Cancer rehabilitation: challenges, approaches, and new directions

Impairments and disability in cancer patients can be caused by the disease process or by its treatment, including the effects of surgery, chemotherapy, and radiation. The prevalence of all cancers, with an estimated 1.4 million new cases in 2006, the development of new treatment options, and improved outcomes have created a constantly growing population of cancer survivors whose function and quality of life have been affected by their diagnoses. This article reviews the theoretical framework, clinical interventions, and research initiatives pertinent to providing rehabilitation services for patients who have been diagnosed with cancer.

Evaluation and Pharmacologic Management of Symptoms in Cancer Patients Undergoing Acute Rehabilitation in a Comprehensive Cancer Center

OBJECTIVES

To identify cancer patients' symptoms at admission and on discharge from an acute rehabilitation unit, to document the discharge medications used for symptom management, and to assess how symptoms affect lengths of stay (LOS).

DESIGN

Retrospective chart review.

SETTING

Acute inpatient rehabilitation unit within a tertiary cancer center.

PARTICIPANTS

Ninety-six patients (49 men, 47 women) were admitted to an acute inpatient rehabilitation unit. The median age was 64 years (range, 26-87y).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Edmonton Symptom Assessment Scale (ESAS) scores at admission and on discharge.

RESULTS

The most intense symptom (mean ESAS visual analog scale score +/- standard deviation) on admission was poor appetite (3.7+/-3.3), followed by fatigue (3.4+/-2.6). Similar results were found for the 63 patients with ESAS scores available at both time points. On discharge, poor appetite (2.2+/-2.4) was still the most intense symptom reported, again followed by fatigue (2.2+/-2.1). There were significant improvements in anxiety (P=.001), constipation (P=.001), fatigue (P=.002), pain (P=.003), appetite (P=.004), sense of well-being (P=.01), and insomnia (P=.04). Seventy percent (65/93) of patients received discharge prescriptions for symptom control, with analgesics being the most frequently prescribed. The poor appetite and depression admission scores correlated positively with hospital LOS (P<.001, P=.05, respectively).

CONCLUSIONS

Assessment of symptoms revealed significant symptom burdens in cancer patients undergoing rehabilitation. Pharmacologic interventions for management of symptoms were frequently needed.

Rehabilitation of surgical cancer patients at University of Texas M. D. Anderson Cancer Center

With early detection and treatment, survival rates for many types of cancer have improved. Long term survivors have number of issues, which can include functional deficits, pain, fatigue, lymphedema and altered bowel and bladder function. Simple activities such as mobility and the ability to perform self care can be limited. In addition, re-integration into society with activities such as driving, social interaction and return to work are often problematic. The goal of cancer rehabilitation is to improve quality of life by minimizing disability and handicap caused by cancer and associated treatments. Initial rehabilitation interventions usually occur in an inpatient setting as patients often experience a decline in functional status due to cancer progression and or surgical treatment. Rehabilitation interventions reduce the debility and functional deficits and add to the quality of life for cancer patients undergoing surgical treatments. The rehabilitation team can assist not only with acute decline in functional status but also with re-integration back in society. Both general and specific rehabilitation interventions based on diagnoses are reviewed.

The Effects of Adjusting for Case Mix on Mortality and Length of Stay Following Radical Cystectomy

PURPOSE

Prior studies evaluating quality of care following radical cystectomy have been constrained by the use of retrospective reviews of single institutional series and limited ability to examine risk factors in a comprehensive manner. Characterization of these factors could enhance preoperative patient counseling and facilitate perioperative management, thereby improving the quality of patient care.

MATERIALS AND METHODS

The National Surgical Quality Improvement Project is a prospective quality management initiative at 123 Veterans Affairs Medical Centers nationwide. The project collects preoperative clinical and intraoperative data, and outcomes on a wide variety of surgical procedures from multiple surgical disciplines. Since 1991, 2,538 radical cystectomies have been captured by the National Surgical Quality Improvement Project. Modeling using logistic regression was performed to identify preoperative risk factors associated with mortality and prolonged length of stay (greater than 90th percentile) after radical cystectomy.

RESULTS

The 30 and 90-day mortality rates following cystectomy were 2.9% and 6.8%, respectively, and median hospital stay was 11 days (90th percentile 30). Robust preoperative factors associated with mortality and prolonged length of stay that uniformly increased risk were older patient age (OR 1.2 to 1.4), American Society of Anesthesiologists class 3 or greater (OR 1.5 to 3.3), dependent functional status (OR 1.7 to 2.0) and low serum albumin (OR 2.1 to 12.0).

CONCLUSIONS

A defined set of preoperative risk factors is independently associated with greater mortality and hospital stay following radical cystectomy. The breadth of these factors suggests that complex case mix adjustment is mandatory when comparing outcomes. Implementation of novel processes directed toward minimizing patient risk has the potential to improve outcomes following cystectomy.
