We aimed at performing a situation analysis to identify challenges that Mexico's peritoneal dialysis centers (PDCs) have faced before and during the COVID-19 pandemic. Methods. From May–August 2021, we conducted a cross-sectional nationwide online survey with the heads of 136 PDCs at the Mexican Institute of Social Security. The survey gathered information about PDCs characteristics and the adaptations and challenges they faced before and during the COVID-19 pandemic. The response rate to the survey was 79.5% (136 out of 171 PDCs). We used descriptive statistics to analyze the data. Results. The survey responses suggest wide variations between PDCs regarding their number of patients, healthcare staff availability, and compliance with the International Society for Peritoneal Dialysis recommendations. In the pre-pandemic period, PDCs faced staff shortages (71.3%); scarcity of supplies (39.0%); catheter dysfunctions (29.4%); poor patient adherence to peritoneal dialysis (PD) (28.6%); and lack of patient support networks (25.7%). During the pandemic, PDCs faced emergent challenges, such as losing designated PDC areas within hospitals (61.0%), and staff and supply shortages (60.2%, 41.1%, respectively) because of a reallocation of human and physical resources towards the COVID-19 response. The pandemic prompted 86.7% of PDCs to implement preventive public health measures (89%), delay non-urgent consultations and procedures (63.6%), and introduce telemedicine (37.3%). Additionally, fewer patients visited PDCs because of their fear of COVID-19 contagion (36.0%). Conclusions. Actions are urgently needed to ensure adherence to evidence-based PD guidelines and sufficient resources, including trained staff, supplies, and designated spaces to strengthen PDCs and provide safe and effective PD. The magnitude of the COVID-19 pandemic and the high risk of severe morbidity and mortality related to this infection are creating new challenges for health services. Healthcare for patients with chronic kidney disease (CKD) is critical given that CKD patients infected with SARS-COV-2 are at a high risk for severe complications and death (1, 2) . Patients with end-stage CKD require renal replacement therapy to improve their quality of life and chances of survival. Renal replacement therapy comprises peritoneal dialysis (PD), hemodialysis (HD), and renal transplantation. The widespread shortage of kidneys for transplantation leads to a greater reliance on PD and HD. PD has been shown to increase survival, quality of life, and satisfaction rates at lower costs than HD (3) (4) (5) (6) (7) . Additionally, unlike patients receiving HD, those on Arch Med Res 21-01523 4 PD are trained by health providers to perform their dialysis procedures at home. Indeed, PD reduces the overuse of health services and increases access to this procedure for patients living in remote areas (8, 9) .These characteristics have made PD particularly useful during the COVID-19 pandemic because it avoids unnecessary potential exposure to SARS-CoV-2, thus reducing the risk of infection and related morbidity and mortality (8) . The Mexican Institute of Social Security (IMSS) is the largest national public institution in Mexico that covers 68 million people, more than half of Mexico's population. IMSS provides healthcare to 73% of people with end-stage CKD who need renal replacement therapy; 53% are treated with PD (10) . In 2018-2019, end-stage CKD was the sixth most frequent cause of hospital admissions and the third chronic disease with the highest financial impact (10) . The COVID-19 pandemic severely affected health care of CKD patients. In 2019, there were 72,237 CKD patients receiving renal replacement treatment at IMSS facilities; by 2020 the figure fell to 69,528. This decline was accompanied by a reduction in IMSS spending on chronic diseases from US $3.8 billion in 2019-US $2.8 billion in 2020 (11) . IMSS has 212 dialysis centers nationwide. According to IMSS recommendations, in the absence of contraindications, PD should be the first line of treatment for CKD patients. In Mexico, CKD patients with COVID-19 are at a higher risk of mortality (12) and peritoneal dialysis centers (PDCs) are the cornerstone of their treatment. Although there have been reports of critical shortages of dialysis staff and equipment during the COVID-19 pandemic in high-income countries (HICs) (13) , this information is still scarce in low-and middle-income countries (LMICs). Therefore, the objective of this study was to perform a situation analysis to identify the challenges that IMSS PDCs have faced before and during the COVID-19 pandemic. We conducted an online mixed-device cross-sectional nationwide survey from May 10 to August 10, 2021in IMSS PDCs. The study participants were heads of PDCs. They were invited to participate through email messages and were granted access to the survey after signing an electronic informed consent form. The form described the purpose of the study, the contents of the survey, the approximate time needed to complete it (25-35 min) , and the voluntary nature of participating. It also specified that participants could end the survey at any time and that there was no monetary or other type of incentive to participate. IMSS has 212 registered dialysis centers nationwide, located within hospital facilities. In 2021, 41 out of 212 dialysis centers did not have PD patients under their care. Therefore, the sample frame consisted of 171 active PDCs that have been providing health care for patients with PD. We obtained the contact information of PDC heads of these 171 centers and invited them to participate. This decision was supported by the study's exploratory nature and the possibility to invite and include the whole studied population. The structured questionnaire collected information on the characteristics of PDCs and identified the challenges to providing PD services. Three researchers with expertise in health services and chronic diseases assessed the survey's questionnaire face validity and reviewed the questions and answer choices (14) . The questionnaire included six open-ended questions on the number of patients receiving care at the respective PDCs and their available staff; changes within the PDCs during the COVID-19 pandemic; and general and COVID-19-specific challenges that PDCs were facing. The questionnaire also had close-ended questions related to PD clinical processes. The questionnaire was pre-tested with three heads of PDCs to ensure its comprehensibility. The electronic questionnaire was created using Google Forms, which allowed for the automatic capture of responses. Cookies were used to assign a unique user identifier. The survey was accessible via mobile device, personal computer, laptop, and tablet and displayed in four sections, as presented in the variables section. Each participant had access to the electronic questionnaire on one occasion; there was no option to return to complete unanswered questions after submitting the questionnaire. However, the response time was not restricted to 30 min, allowing for checking the PDCs' local statistics. We checked the completeness of responses after each questionnaire had been submitted and eliminated duplicate observations from the same IP address (5.4%), keeping the first complete entry for analysis. The study variables comprised: e) Challenges for PDCs before and during the COVID-19 pandemic. PDC challenges were defined as the difficult situations or barriers that a PDC has been facing to provide care for patients with PD. The PDCs challenges were measured using two open-ended questions, one for the challenges before the COVID-19 pandemic (before March 2020) and another for the challenges during the pandemic (from March 2020 till the time of the survey). We did not predefine the answers for these two questions due to the exploratory nature of the study. Arch Med Res 21-01523 8 We performed descriptive analyses calculating the percentages for categorical variables, the mean and standard deviation for numeric variables with a normal distribution (skewness near zero and kurtosis near the value of 3), and median with minimum and maximum for those variables that do not meet normal distribution criteria. We used IBM SPSS Statistics 25 to analyze the data. The openended responses were assessed separately by two researchers (DPM and SVD), who went through every answer to identify response categories one-by-one. After that, the response categories produced by each researcher were cross-checked through their discussion to ensure consistency of the categorization. One hundred thirty-six heads of IMSS PDCs (79.5%) from 171 hospitals in 31 Mexican states participated in the study. Hospitals in the state of Oaxaca were the only ones that did not respond (Supplementary Table 1 ). Most PDC heads were men (71.3%), with a mean age of 41.6 years and standard deviation of 6.5 years. More than half had nursing training (59.6%) and 43.4% were specialized in nephrology. Only 14.7% had worked at their respective PDC for a year or less, while 42.6% had worked there between 1 and 5 years and the rest for more than 5 years (Table 1) . Table 2 Among the standardized PD, 48.0% of patients were usually provided four exchanges of 1.5% glucose solution or four exchanges alternating between 1.5% and 2.5% glucose solutions (26%). However, 26% of PDCs used intensive dialysis with more than ten continuous replacements and less than two hours of permanence in the cavity every 10 d even though the ISPD does not recommend this practice. Only 52.2% of the PDCs performed PET to evaluate peritoneal membrane function and to perform dialysis adjustments; simplified PET was used most often. Table 4 identifies challenges for PDCs before and during the COVID-19 pandemic. Before the pandemic, the main burdens on PDCs were a lack of trained staff (71.3%); supply shortages, particularly dialysis bags and peritoneal catheters (39.0%); catheter dysfunction due to migration, obstruction, or twisting (29.4%); poor patient adherence to PD management instructions (28.6%); insufficient support networks for patients (25.7%); infectious complications, such as peritonitis or exit site infections (17.6%); urgent HD initiation due to delayed referral or patient refusal of PD (16.9%); lack of patient training (13.2%); errors in laboratory tests (e.g., high rates of false-negative cultures due to low volumes of materials or errors in laboratory techniques) (12.5%); an incompatible The present study revealed that PDCs had pre-pandemic health personnel shortages, variability in their adherence to evidence-based clinical recommendations, and limited supplies and infrastructure. (29) . Such measures resulted in treatment delays or discontinuation and poor health outcomes (30) (31) (32) . In Mexico, a study from IMSS identified a substantial decline in the provision of maternal and child health services and those for patients with diabetes and hypertension. For instance, it was estimated that in 2020, breast and cervical cancer screening dropped by 79% and 68%, followed by sick child visits (-66%), contraceptive services (-54%), child vaccinations (-36%), diabetes and hypertension care (-32% in both) and antenatal care (-27%) (33) . Yet the present study is a first that explores the situation faced by the PDCs in Mexico. Public health emergency preparedness is an essential characteristic of resilient health systems (34) . National and institutional plans should be developed to organize an effective response to public health emergencies without weakening essential health services, such as those for patients with CKD. Patient non-attendance at consultations due to their fear of COVID-19 contagion was another challenge that emerged with the pandemic, pointing to the importance of effective COVID-19 preventive measures in the context of providing continuous healthcare to patients with chronic diseases. The World Health Organization issued an operational guidance for maintaining essential health services during the COVID-19 pandemic, highlighting how strengthening communication strategies to support the population's appropriate use of essential services is a crucial part of an effective response (35) . Patients and caregivers PD training is a critical PDC activity that aims to ensure that the patients can perform PD at home safely. The usual patients and caregivers PD training reported by the heads of the PDCs was congruent with the ISPD recommendations (36) . However, during the COVID-19 pandemic, a decrease in patient and caregiver training on PD treatment was identified as another challenge which can be explained by PD staff shortages, the cancelation of non-urgent visits to health facilities, and the fear associated with attending PDCs for both patients and caregivers. Virtual distance training can be a valuable tool in this regard. The primary limitation of this study is that it only includes the opinions of the heads of PDCs on characteristics and challenges of these services; it did not collect the views of health services users. Additionally, although the heads of the PDCs are responsible for preparing monthly performance reports based on the actual statistics and for resolving the challenging situations in their services, we cannot ensure that the local statistics backed all participants' responses or that the responses are totally free from the recall bias that can be presented in any survey. Yet, the time to answer the electronic questionnaire was not restricted, allowing checking of the PDCs' local statistics if necessary. Moreover, the study focuses on IMSS; therefore, future research should include other Mexican health institutions to have a broader perspective on PDCs challenges in Mexico. Finally, the study did not evaluate the quality of care that PDCs provide, as it was not among the study objectives. Given the heterogeneity of certain process of care observed in the studied PDCs, it would be advisable to evaluate their quality of care. We conclude that existing heterogeneity in PD care and the multiple challenges faced by PDCs merit a series of plans and programs to ensure the availability of competent health personnel and to establish mechanisms to ensure that PDCs have sufficient supplies.
