Objective:

Analyze the barriers to access to health care according to Peruvian - Venezuelan nationality in postpartum women in a Public Hospital of Peru 2022 - 2023.

Methods:

Observational, analytical, prospective and cross-sectional study; included a sample of 284 postpartum women of Peruvian and Venezuelan nationality, from the San Juan de Lurigancho Hospital, selected by stratified sampling. The data collection technique was a survey and the instrument was a valid and reliable questionnaire. Pearson's chi-square or Fisher's exact test was used to determine the difference. The association was assessed using the Poisson regression test and the sense of regression using the crude and adjusted prevalence ratio.

Results:

87,3 % of postpartum women were Peruvian and 12,7 % Venezuelan. The most frequent barriers to access to health care in Peruvians were availability: not having all the services necessary for care (p < 0,001) and acceptability: feeling that their beliefs or customs were affected (p < 0,001). Venezuelan postpartum women reported as barriers to acceptability: having received different treatment for being a migrant (p < 0,001) and having felt discrimination during care (p = 0,007).

Conclusions:

There is a significant difference in the barriers to access to health care in postpartum women, with availability and acceptability barriers occurring in Peruvian women and the latter in Venezuelan women.
