Background:
Previous data reveal that females account for a disproportionate majority of all patients diagnosed with diverticulitis.
Objective:
This study analyzed the variation in mortality from diverticular disease by sex.
Design:
This was a nationwide retrospective cohort study.
Settings:
Data were obtained from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research national registry.
Patients:
All citizens of the United States who died from an underlying cause of death of diverticulitis between January 1999 and December 2016 were included.
Main Outcome Measures:
The primary outcome addressed was overall mortality rate of diverticulitis by sex. Secondary outcomes included pattern variances in demographics and secondary causes of death.
Results:
During the study period, 55,096 patients (0.12%) died with an underlying cause of death of diverticulitis from a total of 44,915,066 deaths. Compared with other causes, females were disproportionally more likely to die from diverticulitis than males (0.17% females vs 0.08% males; p < 0.001). Age-adjusted incidence of death was higher for females compared with males. Female patients were less likely to die within the hospital compared with males (OR = 0.72 (95% CI, 0.69-0.75); p < 0.001). Conversely, female patients were more likely to die either at nursing homes or hospice facilities (OR = 1.64 (95% CI, 1.55-1.73); p < 0.001). In addition, females with an underlying cause of death of diverticulitis were less likely to have a surgical complication as their secondary cause of death (OR = 0.72 (95% CI, 0.66-0.78); p < 0.001) but more likely to have nonsurgical complications related to diverticulitis such as sepsis (OR = 1.04 (95% CI, 1.01-1.05); p < 0.03), nonsurgical GI disorders such as obstruction (OR = 1.16 (95% CI, 1.09-1.24); p < 0.001), or chronic pelvic fistulizing disease (OR = 1.43 (95% CI, 1.23-1.66); p < 0.001).
Limitations:
The study was limited by a lack of more specific clinical data.
Conclusions:
Females have a higher incidence of diverticular disease mortality. Their deaths are more commonly secondary to nonsurgical infections, obstruction, or pelvic fistulae. Female patients represent a particularly vulnerable population that may benefit from more intensive diverticulitis evaluation.

Los resultados secundarios incluyeron variaciones de patrones en la demografía y causas secundarias de muerte.Falta de datos clínicos más específicos.Durante el período de estudio, 55.096 pacientes (0,12%) murieron con un UCOD de diverticulitis de un total de 44.915.066 muertes. En comparación con otras causas, las mujeres tenían una probabilidad desproporcionadamente mayor de morir de diverticulitis que los hombres (0.17% F vs. 0.08% M, p <0.001). La incidencia de muerte ajustada por edad fue mayor para las mujeres que para los hombres. Las pacientes femeninas tenían menos probabilidades de morir en el hospital en comparación con los hombres (OR 0.72, IC 0.69-0.75, p <0.001). Por el contrario, las pacientes femeninas tenían más probabilidades de morir en asilos de ancianos o en centros de cuidados paliativos (OR 1.64, IC 1.55-1.73, p <0.001). Además, las mujeres con una UCOD de diverticulitis tenían menos probabilidades de tener una complicación quirúrgica como causa secundaria de muerte (OR 0.72, CI 0.66-0.78, p <0.001) pero más probabilidades de tener complicaciones no quirúrgicas relacionadas con la diverticulitis, como sepsis (OR 1.04, CI 1.01-1.05, p <0.03), trastornos gastrointestinales no quirúrgicos como obstrucción (OR 1.16, CI 1.09-1.24, p <0.001), o enfermedad fistulizante pélvica crónica (OR 1.43, CI 1.23-1.66, p <0,001).Las mujeres tienen una mayor incidencia de mortalidad por enfermedad diverticular. Sus muertes son más comúnmente secundarias a infecciones no quirúrgicas, obstrucción o fístulas pélvicas. Las pacientes femeninas representan una población particularmente vulnerable que puede beneficiarse de una evaluación más intensiva de diverticulitis.
