Telephonic Follow-up and the Risk of Death in Ambulatory Patients with COVID-19.

BACKGROUND: Primary care level close monitoring of mild COVID-19 patients has shown to provide a risk reduction in hospitalization and death. We aimed to compare the risk of all-cause death among COVID-19 ambulatory patients who received and did not receive telephonic follow-up in primary health care settings. METHODS: A secondary database analysis, 2-group comparative study, was conducted with data from the medical information systems of the Mexican Institute of Social Security. A total of 1,498,808 ambulatory patients aged 20 years old and over and with laboratory confirmed SARS-CoV-2 by PCR or rapid antigen test were analyzed. Of them, 535,898 (35.8%) where followed by telephonic calls. The cases were attended from October 14, 2020, to April 10, 2022. Death incidence was evaluated. To assess the association between death and telephonic follow-up we calculated risk ratio using a multivariate logistic model. RESULTS: Case fatality rate was 1.29% in the patients who received telephonic follow-up and 2.95% in the cases who did not receive phone calls. Medical history of chronic kidney disease, COPD, cardiovascular disease, tobacco consumption and diabetes were associated with increased risk of death. In the multivariate model, telephonic follow-up was associated with lower risk of all-cause death, with an adjusted risk ratio of 0.61 (95% confidence interval from 0.59, 0.64). CONCLUSION: Our data suggest that telephonic follow-up is associated with a risk of death reduction in adult outpatients with mild COVID-19, in the context of a multimodal strategy in the primary health care settings.

A Multimodal Strategy to Reduce the Risk of Hospitalization/death in Ambulatory Patients with COVID-19.

BACKGROUND: Different interventions have been implemented worldwide for the house-hold monitoring of patients with mild COVID-19 to reduce the burden of healthcare systems and guarantee quality of care. Telephone follow up and treatment kits have not been evaluated in the context of a national-wide primary care program. AIM OF THE STUDY: To compare the risk of hospitalization and death for COVID-19 between ambulatory patients who received and those who did not receive a treatment kit and telephone follow-up in a developing country METHODS: A two-group comparative analysis was conducted using data from the medical information systems of the Mexican Institute of Social Security. We included a total of 28,048 laboratory-confirmed SARS-CoV-2 patients: 7,898 (28.2%) received a medical kit and 20,150 (71.8%) did not. The incidence rates of hospitalization and death combined were calculated. To identify significant associations between hospitalization or death and treatment medical kits, we calculated the risk ratios using a multivariate logistic model. RESULTS: The incidence of hospitalization was 6.14% in patients who received a kit and 11.71% in those who did not. Male sex, age, and a medical history of obesity, hypertension, diabetes, immunosuppression, or kidney disease were associated with increased risk of hospitalization or death. The risk rates were reduced in patients who received a medical kit or telephone follow-up. In the multivariate model, receiving a medical kit was associated with a lower risk of hospitalization or death from COVID-19: adjusted risk ratio 0.41 (95% confidence interval 0.36-0.47). CONCLUSION: Use of a multimodal strategy may reduce the risk of hospitalization and death in adult outpatients with mild COVID-19.

[PREVENIMSS: a brief overview of its 20 years, challenges and opportunities]. / PREVENIMSS: un breve recorrido de sus 20 años, retos y oportunidades.

Twenty years after its launch, the most ambitious preventive program implemented at the institutional level in Mexico called PREVENIMSS focuses on new challenges and moves towards relaunching. This paper reviews the foundations and design of PREVENIMSS and its evolution throughout these two decades. The PREVENIMS coverage assessment through national surveys set a relevant precedent in evaluating programs at the Mexican Institute of Social Security. PREVENIMSS has shown progress in preventing vaccine-preventable diseases. However, given the current epidemiological profile, there is still a need to provide more effective primary and secondary prevention of chronic noncommunicable diseases. New digital resources and orientation of PREVENIMSS towards a more comprehensive approach that contemplates secondary prevention and rehabilitation can help to face the growing challenges that the program still faces.

A 20 años de su lanzamiento, el programa preventivo más ambicioso implementado a nivel institucional en México llamado PREVENIMSS se enfoca en nuevos desafíos y avanza hacia el relanzamiento. Este artículo hace un breve recorrido de sus fundamentos, diseño y evolución a lo largo de estas dos décadas. La estimación de las coberturas de PREVENIMSS a través de encuestas nacionales también marcó un precedente en la evaluación de programas en el Instituto Mexicano del Seguro Social. PREVENIMSS ha mostrado avances en prevención de enfermedades prevenibles por vacunación, pero aún existe la necesidad de brindar prevención primaria y secundaria más efectivos de las enfermedades crónicas no transmisibles ante el perfil epidemiológico actual. Nuevos recursos digitales y la orientación hacia un enfoque más integral que contemple la prevención secundaria y la rehabilitación pueden ayudar a enfrentar los crecientes desafíos que aún enfrenta el programa.

Introduction: The prevalence of chronic complications and comorbidities in patients with type 2 diabetes (T2D) has increased worldwide. Objective: To compare the prevalence of complications and chronic comorbidities in patients with T2D at 36 family medicine units of five chapters of the Mexican Institute of Social Security (IMSS). Method: Complications (hypoglycemia, diabetic foot, kidney disease, retinopathy, ischemic heart disease, cerebrovascular disease and heart failure) and comorbidities (liver disease, cancer and anemia) were identified according to codes of the International Classification of Diseases, 10th Revision. Comparisons were made by chapter, age, gender and evolution time. Results: Complications and comorbidities were more common in subjects aged ≥ 62 years. Out of 297 100 patients, 34.9 % had any complication; microvascular complications (32 %) prevailed in the industrial North, whereas macrovascular complications (12.3 %) did in the rural East, and comorbidities (5 %) in southern Mexico City. Complications predominated in men (any complication, 30.2 %). Heart failure and comorbidities were more common in women (5.6 % and 4.9 %, respectively). Conclusions: T2D complications and comorbidities showed geographic and gender differences, and were greater with older age and longer evolution time. It is urgent for strategies for the prevention of complications and comorbidities to be reinforced in patients with T2D.

Stepwise strategies to successfully recruit diabetes patients in a large research study in Mexican population.

AIMS: Describe stepwise strategies (electronic chart review, patient preselection, call-center, personnel dedicated to recruitment) for the successful recruitment of >5000 type 2 diabetes patients in four months. METHODS: Twenty-five family medicine clinics from Mexico City and the State of Mexico participated: 13 usual care, 6 specialized diabetes care and 6 chronic disease care. Appointments were scheduled from 11/3/2015 to 3/31/2016. Phone calls were generated automatically from an electronic database. A telephone questionnaire verified inclusion criteria, and scheduled an appointment, with a daily report of appointments, patient attendance, acceptance rate, and questionnaire completeness. Another recruitment log reviewed samples collected. Absolute number (percentage) of patients are reported. Means and standard deviations were estimated for continuous variables, χ2 test and independent "t" tests were used. OR and 95% CI were estimated. RESULTS: 14,358 appointments were scheduled, 9146 (63.7%) attended their appointment: 5710 (62.4%) fulfilled inclusion criteria and 5244 agreed to participate (91.8% acceptance). Those accepting participation were more likely women, younger and with longer disease duration (p<0.05). The cost of the call-center service was $3,010,000.00 Mexican pesos (∼$31.70 USD per recruited patient). CONCLUSIONS: Stepwise strategies recruit a high number of patients in a short time. Call centers offer a low cost per patient.
