ABSTRACT To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan.
We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient's characteristics at PEG using log-rank tests and Cox proportional hazard models.
Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors.
These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors.

    ABSTRACT: PEG is widely used; however, large-scale data for PEG have been lacking. To estimate the prevalence of placement of gastrostomy and jejunostomy tubes and to elucidate the patient background characteristics and their associations with in-hospital mortality. A retrospective analysis of the Japanese administrative claims database. Japanese acute-care hospitals. A total of 64,219 patients who underwent gastrostomy or jejunostomy tube insertion between July and December, 2007 to 2010, were identified among 11.6 million discharge records. Placement of gastrostomy and jejunostomy tubes. In-hospital mortality and the associated risk factors. The mean age was 77.4 years; >90% of patients were aged >60 years. Cerebrovascular disease and pneumonia were the most frequently recorded diagnoses, followed by neuromuscular disease and dementia. The estimated annual number of gastrostomy and jejunostomy placements in Japan ranged from 96,000 to 119,000. The in-hospital mortality was 11.9%, and the significantly associated risk factors were male sex, older age, placement of a jejunostomy tube, urgent admission, hospital with lower bed capacity, the presence of malignancy, miscellaneous diseases, pneumonia, heart failure, renal failure, chronic liver diseases, pressure sores and sepsis, and occurrence of peritonitis and/or GI perforation, GI hemorrhage, and intra-abdominal hemorrhage. Retrospective investigation of administrative database. Our large-scale data revealed the current status of gastrostomy tube placement in Japan. This can contribute to individual decision-making and the public consensus regarding artificial nutritional support in the elderly.

    ABSTRACT: In Japan, there is no decision-making guide regarding long-term tube feeding that specifically targets individuals making decisions on behalf of cognitively impaired older persons (substitute decision makers). The objective of this study was to describe the development and evaluation of such a decision aid. In this before-and-after study, participants comprised substitute decision makers for 13 cognitively impaired inpatients aged 65 years and older who were being considered for placement of a percutaneous endoscopic gastrostomy tube in acute care hospitals and mixed-care hospitals in Japan. Questionnaires were used to compare substitute decision makers' knowledge, decisional conflict, and predisposition regarding feeding tube placement before and after exposure to a decision aid. The acceptability of the decision aid was also assessed. Paired t-tests were used to compare participants' knowledge and decisional conflict scores before and after using the decision aid. Substitute decision makers showed significantly increased knowledge (P < .001) and decreased decisional conflict (P < .01) regarding long-term tube feeding after using the decision aid. All substitute decision makers found the decision aid helpful and acceptable. The decision aid facilitated the decision-making process of substitute decision makers by decreasing decisional conflict and increasing knowledge.

    ABSTRACT: To evaluate long-term survival and prognostic factors in elderly Mexican patients who have undergone percutaneous endoscopic gastrostomy (PEG). The present study was a retrospective cohort analysis of 110 patients aged older than 70 years without head and neck malignancy who underwent PEG between January 2005 and December 2012. Odds ratios (OR) and 95% confidence intervals (CI) were calculated for demographic and clinical variables, and survival was determined by the Kaplan-Meier method. Medium age and follow up were 82.45 ± 6.6 years and 688.3 ± 394.6 days, respectively. The patients who died in the early postoperative period (n = 6) were older than those who survived. The Karnofsky performance status and lymphocyte count were non-significantly lower in non-survivors. The body mass index and serum albumin level were lower in non-survivors (P = 0.03 and 0.01, respectively) and Charlson's Comorbidity Index (CCI) was higher. A total of 32 (29%) patients died later in the postoperative period with a mean follow up of 436.2 ± 267.4 days. Risk factors for mortality included Karnofsky Performance Status (odds ratio [OR] 9.76, 95% CI: 3.26-29.3), CCI (OR 7.04, 95% CI: 2.31-21.41) and postoperative hypoalbuminemia (OR 3.45, 95% CI: 1.71-6.67). Postgastrostomy pneumonia occurred in 36.8% of the patients who died during follow-up (OR 0.28, 95% CI: 0.6-1.26). Karnofsky performance status, Charlson's comorbidity index and postoperative hypoalbuminemia, were independent risk factors for mortality. Modifiable factors are related to nutritional support. Early PEG may help prevent malnutrition and infection. Geriatr Gerontol Int 2013; ●●: ●●-●●.
