A retrospective study of 27,000 gastroparesis patients showed that the risk of mortality in the elderly with emergent gastroparesis was seven-fold higher when compared to adults. The odds of mortality raised by 8% for every year rise in age in elderly people and by 4% in adults. Researchers undertook this analysis to determine the risk factors implicated in the mortality of 27,000 people admitted with primary diagnosis of gastroparesis.

The data from National Inpatient Sample for people diagnosed with gastroparesis were considered. Stratification of data was done as per various factors of interest for identifying risk factors implicated in mortality. This was done with the aid of statistical tools, involving a multivariable logistic regression model with backward elimination.

In comparison with elderly patients (N=71, mean age 75 years), the adult patients (N=39, mean age 43 years) exhibited a reduced mortality rate (1.27% vs. 0.18%) The females accounted for the majority of volunteers in both elderly (71%) and adult (73.7%) populations. There was a profound link between mortality and age in both elderly (Odds ratio [OR]=1.08) and adults (OR=1.04). Compared to adult males, the adult females exhibited a considerably longer hospital length of stay (4.41 days, Standard deviation [SD]=5.10 vs. 5.08 days, SD=5.04)

There was a profound relation between mortality and hospital length of stay in both adults (OR=1.12) and elderly people (OR=1.10). In comparison with the elderly (9.6%, N=538), a reduced percentage of adults (6.6%, N=1,402) underwent an operation. The mean time to surgery was 4.76 days (SD=5.37) for adults who survived and 17.50 days (SD= 9.37) for adults who did not survive.

On the contrary, this value was 5.57 and 9.10 days for the elderly (SD=6.50 and 7.15, respectively). In people who underwent an operation, a profound link was noted between mortality and time to operation for both elderly patients (OR=1.05) and adult patients (OR=1.17).
