Pulmonary exercise testing, including six-minute walk tests, exercise oximetry, and independent exercise assessments, are critical tools for managing chronic respiratory and cardiac conditions, evaluating treatment response, and determining long-term oxygen therapy needs. During the COVID-19 pandemic, testing was reduced to limit viral spread. This study aimed to evaluate post-pandemic trends of pulmonary exercise testing utilization in Ontario overall and across demographic groups. We conducted a population-based cohort study using Ontario administrative data between April 2015 and December 2023 to evaluate pulmonary exercise testing before, during, and after the COVID-19 pandemic. We used an Auto-Regressive Integrated Moving Average Model (ARIMA) model and incidence rate ratios to evaluate recovery trends. Subgroup analysis examined if trends were similar in different groups. During the study period, 505,902 tests were performed for 362,888 individuals. As of December 2023, testing rates were still 21% below pre-pandemic levels (IRR 0.79, 95%CI 0.70-0.89). Recovery was lower in males (IRR 0.76, 95%CI 0.66-0.86) and individuals living in lower socioeconomic status neighborhoods (IRR 0.71, 95%CI 0.58-0.86). Northern Ontario saw the most pronounced shortfall compared to other regions, with testing rates one-third of pre-pandemic levels (IRR 0.33, 95% CI 0.26-0.43). More than three years after the pandemic began, pulmonary exercise testing rates have yet to return to pre-pandemic levels, with certain groups disproportionately affected. This highlights a significant and ongoing disruption in diagnostic capacity and quality of care for people with respiratory and cardiac diseases.

Studies have reported evidence about the effectiveness of a third dose with BNT162b2 for preventing hospitalization and death by COVID-19. However, there is little evidence regarding other primary vaccine schedules such as BBIBP-CorV and ChAdOx1-S. We estimated the relative vaccine effectiveness (RVE) of the booster dose versus the primary regimens of COVID-19 vaccines based on BBIBP-CorV, ChAdOx1-S, or BNT162b2 for preventing death during the Omicron wave in Peruvian adult people. We carried out a nested case-control study with a risk set sampling of controls using data from Peru between December 20, 2021, and February 20, 2022 (during the Omicron wave). Data on vaccination, COVID-19 tests and deaths were collected from national surveillance databases. We performed conditional logistic regression models to estimate the RVE on the adult population. In addition, we executed sub-group analysis per age group (18 to 59 years, and 60 years or more) and per primary regime (based on BNT162b2, BBIBP-CorV, or ChAdOx1-S). Of the 11,188,332 people eligible to enter the study 1,974 met the case definition (death from COVID-19) and were matched to 9,183 controls. The overall RVE of a third dose to prevent death was 87.2% (84.2%-89.7%), which varied according to the primary regime (87.3% for BNT162b2, 82.0% for BBIPB-CorV-2, and 79.5% for ChAdOx-S). In older adults, the RVE was 87.1%, without significant variations according to the primary regime (86.1% for BNT162b2, 86.1 for BBIBP-CorV, and 82% for ChAdOx-S). The booster) dose of vaccine against COVID-19 had a high RVE for preventing death by COVID-19 in the Peruvian population in all primary regimes of vaccines during the Omicron wave. This effect was consistent in people over 60 years of age, the group most vulnerable to die from this infection.

ObjectivesAccurate civil registration and vital statistics (CRVS) systems are the primary data source to measure the impact of the COVID-19 pandemic on mortality. This study assesses how the pandemic impacted CRVS system processes in Loreto region of Peru, one of the worst affected countries globally.DesignQualitative study.SettingLoreto, a remote region, which had the highest reported mortality rate in Peru during the pandemic.ParticipantsSemistructured individual interviews and documentary analysis were conducted between September 2020 and May 2021 with 28 key informants from eight institutions involved in death certification. Key informants were identified using a purposive sampling strategy commencing at the Health Directorate of Loreto, and the snowball method was used where a participant suggested another organisation or person. Information from key informants was used to compare business process maps of the CRVS system before and during the pandemic.ResultsDuring early May 2020, there were seven times more registered deaths than in earlier years, but key informants believed this underestimated mortality by 20%–30%. During the pandemic, families had to interact with more institutions during the death certification process. Several issues disrupted death certification processes, including the burden of increased deaths, the Environmental Health Directorate often removing a body without the family’s express agreement, the creation of COVID-19 cemeteries where no death certificate was needed for burial, greater participation of funeral homes that often used outdated paper forms, and closure of civil registry offices. There was increased use of the online National Death System (SINADEF) but many users had problems with access.ConclusionsThe pandemic substantially disrupted CRVS processes in Loreto, making death certification more difficult, placing greater burden on the family and leading to more participation from unregulated organisations such as funeral homes or cemeteries. These disruptions were impacted by limitations of the CRVS system’s processes before the pandemic.

The administration of a third (booster) dose of COVID-19 vaccines in Peru initially employed the BNT162b2 (Pfizer) mRNA vaccine. The national vaccination program started with healthcare workers (HCW) who received BBIBP-CorV (Sinopharm) vaccine as primary regimen and elderly people previously immunized with BNT162b2. This study evaluated the reactogenicity and immunogenicity of the \"booster\" dose in these two groups in Lima, Peru. We conducted a prospective cohort study, recruiting participants from November to December of 2021 in Lima, Peru. We evaluated immunogenicity and reactogenicity in HCW and elderly patients previously vaccinated with either two doses of BBIBP-CorV (heterologous regimen) or BTN162b2 (homologous regimen). Immunogenicity was measured by anti-SARS-CoV-2 IgG antibody levels immediately before boosting dose and 14 days later. IgG geometric means (GM) and medians were obtained, and modeled using ANCOVA and quantile regressions. The GM of IgG levels increased significantly after boosting: from 28.5±5.0 AU/mL up to 486.6±1.2 AU/mL (p<0.001) which corresponds to a 17-fold increase. The heterologous vaccine regimen produced higher GM of post-booster anti-SARS-CoV-2 IgG levels, eliciting a 13% increase in the geometric mean ratio (95%CI: 1.02-1.27) and a median difference of 92.3 AU/ml (95%CI: 24.9-159.7). Both vaccine regimens were safe and well tolerated. Previous COVID-19 infection was also associated with higher pre and post-booster IgG GM levels. Although both boosting regimens were highly immunogenic, two doses of BBIBP-CorV boosted with BTN162b2 produced a stronger IgG antibody response than the homologous BNT162b2 regimen in the Peruvian population. Additionally, both regimens were mildly reactogenic and well-tolerated.

The COVID-19 pandemic required a rapid transition to virtual care as a key strategy to maintain healthcare access while minimizing virus transmission risks. However, the impact of this shift on hospitalizations and emergency department (ED) visits for ambulatory care-sensitive conditions (ACSCs) remains unclear. This study aims to assess the relationship between the modality of outpatient care for ACSCs and their outcomes in Ontario, Canada. In this population-based retrospective cohort study, we analyzed hospitalization and ED visit data for ACSCs, including diabetes, epilepsy, congestive heart failure, hypertension, and angina, during the pandemic (April 2020 to April 2023) and post-pandemic (May 2023 to August 2023) periods. Monthly trends in hospitalizations and ED visits were evaluated using Generalized Additive Models and Generalized Additive Mixed Models, accounting for the effects of virtual and in-person care within 30 days and 60 days preceding each event. Despite a notable decrease in virtual visits and a corresponding rise in in-person visits, overall hospitalizations and ED visits for ACSCs remained relatively stable. Our analysis found no significant association between care modality and changes in hospitalizations and ED visits, suggesting that virtual care, particularly during the early pandemic, effectively supported chronic disease management and contributed to the stability of acute care needs. In conclusion, virtual care proved to be a sustainable component of ACSC management during and after the COVID-19 pandemic, complementing in-person care.

Background Telementoring seems to be a promising strategy to deliver training and counselling to physicians in remote areas. In Peru, early graduated physicians must work for the Rural and Urban-Edge Health Service Program where they face important training needs. The aim of this study was to describe the usage of a one-on-one telementoring program for rural physicians and evaluate the aspects related to the perceptions of acceptability and usability. Methods Mixed methods study on recently graduated physicians who work in rural areas and participate in the telementoring program. The program used a mobile application to connect these young doctors with specialized mentors to answer queries about real-life problems raised by working in a rural area. We summarize administrative data to assess participant characteristics and their participation in the program. Additionally, we conducted in-depth interviews to explore the perceived usability, ease of use, and reason for non-use of the telementoring program. Results Of 74 physicians (mean age 25, 51.4% women) enrolled, 12 (16.2%) actively used the program and performed a total of 27 queries, which received response in an average time of 5.4 ± 6.3 h. In the interviews, the main reasons for non-use were connectivity issues, feelings of shame, and self-efficacy. For those who used the telementoring program they referred it was easy to use and solve their inquiries timely. Conclusions The implementation of a telementoring program sought to provide guidance to recently graduated physicians working in rural areas. Low use rates show that administrative and process-related deficiencies in the program implementation need to be improved.

During the pandemic in Peru, the COVIDA (Collaboration Network of Volunteer Brigade Members for the Investigation, Detection, and Primary Management of Community Cases Affected by COVID-19) project proposed an innovative way to provide telemonitoring and teleorientation to COVID-19 patients, led by health care student volunteers. However, it has not been described how this interaction is perceived from the patient's perspective and which factors increase their engagement with this service. The aim of this study is to describe the perceptions of patients about COVIDA and identify factors associated with their engagement with this service. A mixed methods study was conducted to evaluate perceptions of patients that participated in the COVIDA project. This telehealth intervention organized by the National University of San Marcos was implemented in Peru from August to December 2020. The service involved daily phone calls by volunteer students to monitor registered COVID-19 patients until the completion of the 14th day of the illness or if a warning sign was identified. The volunteers also provided teleorientation to address the patients' needs and concerns. Quantitative analysis was performed to describe the characteristics of the patients and to assess the factors related to their engagement with the service, which was defined by the percentage of participants who completed the follow-up according to their individual schedule. Qualitative analysis through semistructured interviews evaluated the patients' perceptions of the service regarding the aspects of communication, interaction, and technology. Of the 770 patients enrolled in COVIDA, 422 (55.7%) were female; the median age was 39 (IQR 28-52) years. During the monitoring, 380 patients (49.4%) developed symptoms, and 471 (61.2%) showed warning signs of COVID-19. The overall median for engagement was 93% (IQR 35.7%-100%). Among those patients who did not develop warning signs, engagement was associated with the presence of symptoms (OR 3.04, 95% CI 2.22-4.17), a positive COVID-19 test at the start of follow-up (OR 1.97, 95% CI 1.48-2.61), and the presence of comorbidities (OR 1.83, 95% CI 1.29-2.59). Patients reported that the volunteers provided clear and valuable information and emotional support. Communication via phone calls took place smoothly and without interruptions. COVIDA represents a well-accepted and well-perceived alternative model for student volunteers to provide telemonitoring, teleorientation, and emotional support to patients with COVID-19 in the context of overwhelmed demand for health care services. The deployment of this kind of intervention should be prioritized among patients with symptoms and comorbidities, as they show more engagement with these services.

El objetivo de este trabajo fue determinar la asociación entre los factores motivacionales y el desempeño laboral, en los tecnólogos médicos en el área de radiología. Para esto se realizó un estudio descriptivo de corte transversal, analítico correlacional, en el cual se utilizaron como instrumentos de recolección de datos el «Test de evaluación de factores motivacionales» (para medir los factores motivacionales según F. Herzberg) y la «Ficha de Evaluación del desempeño laboral» (para medir el desempeño laboral de los participantes, según evaluación de su jefatura). Posteriormente, se determinó la asociación entre los FM y el desempeño laboral. Para el análisis estadístico se utilizó el programa Microsoft Excel, programa estadístico Stata v.16.0 y la correlación de Pearson. La población y la muestra estuvo compuesta por N=77 y n=64 participantes, respectivamente. Entre los factores motivacionales más resaltantes fueron el crecimiento profesional, relaciones con los compañeros, logro y seguridad laboral, con puntajes promedio de 9.015 ± 1.923, 8.812 ± 2.259, 8.406 ± 2.060 y 8.203 ± 2.520, respectivamente. A su vez, el desempeño laboral obtenido fue regular (7.81 %), bueno (28.13 %) y muy bueno (64.06 %). Con respecto a la asociación existente entre factores motivacionales y desempeño laboral, de los 15 factores motivacionales estudiados, los valores de mayor relevancia fueron obtenidos por «seguridad laboral» (r: 0.2511, p=0.04) y «relaciones con el jefe» (r: -0.2508, p=0.04). Se concluye que Los factores motivacionales «seguridad laboral» y «relaciones con el jefe» tienen una asociación significativa con el desempeño laboral en los TM del área de radiología. Donde se evidenció que, a mayor priorización de los factores motivacionales de las relaciones con el jefe, menor es el nivel de desempeño laboral; y que contrariamente, a mayor priorización de los factores motivacionales, mayor es el nivel de desempeño laboral.

During 2021, Peru started the vaccination against SARS-CoV-2 using the BBIBP-CorV inactivated virus vaccine for health care workers (HCW). We aim to evaluate the effectiveness of the BBIBP-CorV vaccine to prevent SARS-CoV-2 infection and deaths among HCWs. Retrospective cohort study, from February 9 to June 30, 2021, using national registries of health care workers, laboratory tests for SARS-CoV-2 and deaths. We calculated the vaccine effectiveness for preventing laboratory-confirmed SARS-CoV-2 infection, COVID-19-mortality, and all-cause mortality among partially immunized and fully immunized HCWs. An extension of Cox proportional hazards regression was used to model the mortality results, and Poisson regression was used to model SARS-CoV-2 infection. The study included 606,772 eligible HCWs, the mean age was 40 (IQR: 33.0, 51.0). In fully immunized HCW, the effectiveness for preventing all-cause mortality was 83.6 (95% CI: 80.2 to 86.4), 88.7 (95% CI: 85.1 to 91.4) for preventing COVID-19 mortality, and 40.3 (95% CI 38.9 to 41.6) for preventing SARS-CoV-2 infection. The BBIBP-CorV vaccine showed high levels of effectiveness for preventing all-cause and COVID-19 deaths among fully immunized HCW. These results were consistent within different subgroups and sensitivity analyses. However, the effectiveness for preventing infection was suboptimal in this particular setting. •The effectiveness of BBIBP-CorV in peruvian healthcare workers was evaluated.•During the Peruvian second wave of infections, lambda and gamma variants circulated.•Effectiveness was 40.3% for SARS-CoV-2 infection and 88.7% for death due to COVID-19.•BBIBP-CorV was useful to prevent death during vaccine constraint in the global south.

In Peru, there is an increase in the creation of mobile health (mHealth) apps; however, this situation could present problems related to the quality of information these apps share, data security and privacy, usability, and effectiveness, as there is no specific local regulation about their creation and use. The objective of this study was to review mHealth apps created, uploaded, or used in Peru, and perform an analysis of the national regulatory framework that could be applied to evaluate whether there is a need to develop and implement a specific regulation to these apps. A total of 3 reviews were performed. First, we reviewed information about Peruvian mHealth apps created up to May 2019 from scientific publications, news, government communications, and virtual stores, and evaluated their purpose, creator, and the available evidence of their usability and effectiveness. The second review was carried out by taking a sample of the 10 most commonly used mHealth apps in Peru (regardless of the country of creation), to evaluate the information they collect and classify them according to the possible risks that they could present in terms of security and privacy. In addition, we evaluated whether they refer to or endorse the information they provided. Finally, in the third review, we searched for Peruvian standards related to electronic health (eHealth) that involve information technology that can be applied to regulate these apps. A total of 66 apps meeting our inclusion criteria were identified; of these, 47% (n=31) belonged to government agencies and 47% (n=31) were designed for administrative purposes (private and government agencies). There was no evidence about the usability or effectiveness of any of these apps. Concerning the 10 most commonly used mHealth apps in Peru, about the half of them gathered user information that could be leaked, changed, or lost, thus posing a great harm to their users or to their related patients. In addition, 6/10 (60%) of these apps did not mention the source of the information they provided. Among the Peruvian norms, the Law on the Protection of Personal Data, Law on Medical Devices, and administrative directives on standards and criteria for health information systems have some regulations that could be applied to these apps; however, these do not fully cover all aspects concerning the evaluation of security and privacy of data, quality of provided information, and evidence of an app's usability and effectiveness. Because many Peruvian mHealth apps have issues related to security and privacy of data, quality of information provided, and lack of available evidence of their usability and effectiveness, there is an urgent need to develop a regulatory framework based on existing medical device and health information system norms in order to promote the evaluation and regulation of all the aforesaid aspects, including the creation of a national repository for these apps that describes all these characteristics.
