Objective: Effective dengue management enhances the chances of survival. The level of adherence to the suggestions in northern Peru is uncertain. The primary aim of the study was to assess adherence to the 2016 PAHO guideline on dengue in a hospital located in northern Peru during the period from 2022 to 2023. Material and methods: The study performed a cross-sectional design and exploratory analysis, reviewing 140 medical records. Fifty-four percent were from 2023; 66.43% were from women; 38,57% came from a first level healthcare center; 77.14 % had diagnosis of dengue with warning signs and 20.71% had severe dengue; 18.44% died. Results: We found at least one error in the classification of severity and/or treatment in non-hospital healthcare facilities (95 %), triage (90.23%), and uviclin/observation (58.93%). Errors in classification and inadequate hydration in the first level healthcare centers, triage, and uviclin/observation were: 40.68%/60.0%, 31.0.6%/76.6%, and 15.32%/44.14 %, respectively. Persistent errors were inadequate hydration in triage (76.69%) and urinary flow in the center (81.67 %). In a bivariate analysis, mortality was associated with age 18 years or older (p = 0.047), having a case from 2023 (p = 0.008), and having severe dengue (p<0.001). In the multivariate analysis, only severe dengue (PR: 28.13, 95% CI :9.32-84.86 p<0.001), and age 18 years or older (PR:2.97, 95%CI:1.19-7.43 p: 0.020), were associated with mortality. Conclusions: We found a high frequency of misclassification and management errors in these three scenarios, but they were not associated with higher mortality.

Objetivo. El manejo adecuado del dengue mejora las probabilidades de supervivencia. Sin embargo, se desconoce el nivel de adherencia a las recomendaciones vigentes en el norte del Perú. El objetivo principal de este estudio fue evaluar la adherencia a la guía de dengue de la Organización Panamericana de la Salud (OPS) de 2016 en un hospital del norte del Perú durante el período 2022–2023. Material y métodos: Se realizo´ un estudio de diseño transversal y análisis exploratorio mediante la revisión de 140 historias clínicas. El 54 % correspondió al año 2023; el 66,43 % fueron mujeres; el 38,57 % provenía de establecimientos de salud del primer nivel de atención; el 77,14 % tenía diagnóstico de dengue con signos de alarma y el 20,71 % de dengue grave; el 18,44 % falleció. Resultados: Se encontró al menos un error en la clasificación de la gravedad y/o en el tratamiento en los establecimientos de salud no hospitalarios (95 %), en triaje (90,23 %) y en la unidad clínica/observación (58,93 %). Los errores en la clasificación y la hidratación inadecuada en los establecimientos del primer nivel de atención, triaje y unidad clínica/observación fueron de 40,68 %/60,0 %, 31,06 %/76,69 % y 15,32 %/44,14 %, respectivamente. Los errores persistentes más frecuentes fueron la hidratación inadecuada en triaje (76,69 %) y el monitoreo inadecuado del flujo urinario en hospitalización (81,67 %).En el análisis bivariado, la mortalidad se asoció´ con tener 18 años o más (p = 0,047), corresponder al año 2023 (p = 0,008) y presentar dengue grave (p < 0,001). En el análisis multivariado, únicamente el dengue grave (RP: 28,13; IC 95 %: 9,32–84,86; p < 0,001) y la edad igual o mayor de 18 años (RP: 2,97; IC 95 %: 1,19–7,43; p = 0,020) se asociaron con la mortalidad. Conclusiones: Se encontró´ una alta frecuencia de errores en la clasificación y el manejo de los pacientes en los tres escenarios evaluados; sin embargo, estos errores no se asociaron con una mayor mortalidad.

In the Americas, in 2023, there were 4´563, 485 cases of dengue, 7,653 cases of severe dengue (0.16%) and 2,339 deaths (0.05% mortality). After Brazil, Peru had the second highest number of cases (274,277 cases), with 441 deaths (0.16%), which is 3.2 times the average for the Americas (1).
Peru recorded a total of 13,010 cases and 8 fatalities up until epidemiological week 5. Among these instances, the city of Piura in the northern region reported 2,153 cases. (2).
Although this virus's mortality is less than 1%, complications and deficiencies in early management can increase it. The key factors for
improving prognosis are early syndromic diagnosis, patient individualization, monitoring, and adequate hydration. (3).
In 2016, the Pan American Health Organization (PAHO) developed the Guidelines for patient care in the Region of the Americas 2nd edition, based on available evidence from cohort studies and expert opinions. in which they emphasize the correct initial management according to risk factors and symptomatology for adequate triage and treatment, according to the widely recognized classification: Dengue without warning signs (DWWS), Dengue with warning signs (DWS) and Severe Dengue (SD) (4). Within the Peruvian
contingency plan of the Ministry of Health (MINSA) against Dengue, in October 2023, a National
Directive was issued ensuring a budget of 107,585,222 PEN for the program 017 Metaxenic and zoonotic diseases, of which more than 16,000,000 PEN were assigned to the MINSA and more than 91,000,000 PEN to the Regional Governments, aimed to strengthen the skills and competencies of healthcare professionals in the management and approach of this problem and to develop research in this pathology. Likewise, this regulation exposed the deficit in adherence to the Clinical Practice Guidance (CPG) recommendations and the lack of research and exploration of the problems related to it (5). On the other hand, in our country, in March 2024, the Technical Health Standard No. 211-MINSA/DGIESP-2024 was implemented, with clear specifications on prevention and treatment at diverse levels of care
(6). This allowed us to adopt an anticipatory and prospective attitude in the evaluation of the patient. To implement a guide, it is necessary to educate in all areas of care and train all healthcare personnel through validated educational interventions with theoretical and practical content. In other words, it is necessary to train and measure to know how we are, where we are going, what we need to improve and how we will do it. Adherence to recommendations can provide better clinical outcomes (8).
There is evidence that the knowledge, attitudes, and practices in the comprehensive management of this endemic disease are far from ideal. In the 2022 outbreak, studies on patients hospitalized for DWS and SD in a Level II-2 hospital of the Ministry of Health of Piura found delays in reference time, prolonged time in triage and frequent errors in severity classification, hydration, and monitoring
(9). In Colombia, a review of 43 medical records for the characterization of adherence to the 2010 PAHO CPG, found that the overall adherence level was 67.4% and the items with the lowest compliance were: evaluation capillary refill, search for hemorrhages in the skin and mucous membranes, evaluation of warning signs and examination of the central nervous system (10). In another Colombian study in pediatric patients, it was found that 77.18% were correctly classified and 28.9% received adequate hydration management (11).
Since Piura is the city with the most cases of dengue reported in the period 2023–2024 and deficiencies have been evident in 2022, this study aims: a) to describe the most frequent errors in the classification of the severity and management of admitted dengue cases to a public hospital in the city of Piura in the years 2022–2023 and b) to explore their association with the severity and mortality of dengue.
Design. This is a cross-sectional descriptive study with exploratory analytical analysis.
Study site. The region of Piura (2,127,000 inhabitants) is the second department with the largest population in Peru (12). The Ministry of Health of Peru rates the Hospital study's site, as Level II-2. (13) In 2023, it had Emergency Room Triage (20 beds), Pediatric Emergency Services (12 beds), Obstetrics and Gynecology Emergency Services (10 beds), Medicine Emergency (20 beds), and Surgery Emergency (14 beds); two Dengue Monitoring Units named Uviclin (Uviclin 1: [12 beds] and Uviclin 2: [40 beds]); an Intensive Care Unit (pediatrics, intermediate care, and general: [32 beds]); Internal Medicine Hospitalization (50 beds); Surgery (40 beds); Obstetrics and Gynecology Hospitalization (14 beds); and Pediatrics (13 beds). Up until the last patient's description, the hospital had a total of 277 beds available. The hospital has handwritten registration and information management does not have electronic medical records for hospitalization.
Population and study sample. The study population was the medical records of patients with DWS and SD, hospitalized in at least one of the services.
Selection criteria. The records of patients with or without referral from another health care facilities
and followed until their permanence in observation and/or Uviclin and/or ICU were considered .We included stories with confirmation of a case of dengue with warning signs or severe dengue, by the hospital's epidemiology office Medical records from 2022 and epidemiological weeks 18-25 of 2023 (peak of the outbreak).The records of patients with or without referral from another health care facilities and followed until their permanence in observation and/or Uviclin and/or ICU were considered Sampling was by convenience according to the availability of the medical records. With a population of 939 records, confidence level of 97%, design effect of 1 and frequency of non-registration/no data available for mean arterial pressure in Triage of 11.3% (9) (previous study from 2022), the calculated sample size was 158 stories.
Information from medical records and definitions. SCR, AMR (Infectious diseases physicians) and FLJ (internal medicine physician) developed a checklist to describe adherence to the application of the Guidelines for the care of patients in the region of the Americas - Second edition of the Pan American Health Organization (4) and the Technical Health Standard for the Comprehensive Care of Patients with Dengue in Peru, 2024 (6). With both the relevance of the initial diagnosis, severity classification, hydration (bolus and infusion) and monitoring from the health
centers/posts until passing through the hospital were evaluated. Dengue (DENV) was defined as WHO: “Dengue (break-bone fever) is a viral infection that spreads from mosquitoes to people.
It is more common in tropical and subtropical climates. Most people who get dengue will not have symptoms. But for those who do, the most common symptoms are high fever, headache, body aches, nausea, and rash. Most will get better in 1–2 weeks. Some people develop severe dengue and need care in a hospital “(3).
The algorithms followed were:
A. Dengue case algorithm with warning signs:
1. Start hydration with crystalloid solution (Hartman or 0.9% saline solution): 10cc/kg to pass in one hour, up to 3 loads; If there is no clinical improvement change to the severe dengue algorithm.
2. Gradual reduction of hydration to 5-7 ml/kg/h for 2-4 hours and hourly monitoring.
3. Reevaluation of the patient. If clinical improvement is evident and urine output is ≥ 1 ml/kg/h, reduction of hydration to 3-5 ml/kg/h for 2-4 hours and hourly monitoring.
4. Reevaluation. If clinical improvement is evident and urine output is ≥ 1 ml/kg/h, reduce hydration to 2-4 ml/kg/h and continue for 24-48 hours and hourly monitoring.
B. Severe Dengue Case Algorithm:
1. Immediate bolus administration of crystalloid solution (Hartman or 0.9% normal saline) 20 ml/kg in 15 to 30 minutes.
2. Reevaluation. If signs of shock disappear, decrease hydration to 10 ml/kg/h for 1-2 hours and hourly monitoring.
3. Reevaluation. If the evolution is satisfactory, decrease hydration to 5-7 ml/kg/h for 4-6 hours and hourly monitoring.
4. Reevaluation. If the evolution is satisfactory, reduction of hydration to 3-5 ml/kg/h for 2-4 hours and hourly monitoring.
5. If evolution is satisfactory, reduce fluids to 2-4 ml/kg/h for 24-48 hours.
In addition, the following were measured: Presence of the referral form from the healthcare center (presence and adequate completion), time elapsed from the reference from the health center to arrival at the hospital, and times spent in each service.
Two aspects were determined: 1. Appropriate initial diagnosis and 2. Appropriate management. Each researcher was assigned a defined number of records. They were previously trained by SCR and AMR.
Adequate initial diagnosis was defined if the diagnosis that appeared on the reference, triage and observation/Uviclin sheet coincided with the investigator's opinion: DWWS, DWS, SD.
Adequate management was defined if the indications in the evolution or monitoring sheets coincided with the researcher's evaluation in relation to parenteral fluid therapy, the frequency of monitoring vital functions (mean arterial pressure, diuresis) and the indication for blood products (all should be met).
For the evaluation of diagnosis and management of Dengue, confirmed and probable cases of dengue were included, as well as those ruled out since the outbreak scenario and the concept of case management were considered. If the written information was not found in clinical history, it would be considered indeterminate.
Statistical Analysis. Descriptive analysis with absolute and relative frequencies for categorical variables and measures of median and interquartile range (IQR) for numerical variables were estimated. The association between severity and mortality and adequate initial diagnosis and appropriate management was explored. Chi 2 and Fisher's test were used for categorical tests and Wilcoxon/Student's t test for numerical tests according to normality. A multivariable analysis was performed between mortality and diagnostic classification, sociodemographic and appropriate management classification with p <0.1 in the bivariate. Prevalence ratios were calculated through generalized linear models using the link log function and the binomial family with robust variance. For the statistical analysis we used StataCorp. 2023.

Ethical aspects. The Hospital Research Committee approved the study protocol. The confidentiality of the information was maintained, and the databases were worked without identifiers. We delivered a final report to the hospital's general management and shared the results with the authorities and the hospital's dengue team.
The Minister of Health's Epidemiology Surveillance System (ESS) reported 208 cases of DENV in 2022; between weeks 18 and 25, in 2023, they reported 731 cases, for a total of 939. We evaluated 141 medical records. For the mortality analysis, only 140 cases were considered since the final outcome was not found in one.
General characteristics of these cases. Sixty-six percent of the medical records were from women, almost 67/141 (47.51%) were previously in a healthcare center or other hospital; 31.20% had between 1-4 hours of delay in their referral, 56.73% were between 1-4 hours in triage, 76.60% had dengue with alarm signs, and 32% were in Uviclin and deceases 18.44% (see table 1).

When considering the classification of severity or treatment, at healthcare facilities outside of the study site, triage and Uviclin/observation, there were a frequency of at least one error in 91.5%, 88.5% and 52.6%, respectively (see table 2). To explore the association between sociodemographic features, hospital care variables and severity/mortality, voluntary withdrawals were considered alive until discharge and the observation of “missing data” was eliminated for the final outcome (n =140).
When comparing the presence of at least one error in the healthcare center, triage and observation/Uviclin, no difference was found in mortality: p= 0,486, p= 0.281, p= 0.85 (see table 3). In the exploratory multivariate analysis, only severe dengue (PR: 28.13, 95% [CI , 9.32-84.86] p<0.001), and age 18 years or older (PR:2.97, 95%[CI, 1.19-7.43] p: 0.020), were associated with mortality. Neither the presence of at least one error in the center (p= 0.486), triage (p=0.281), and observation/uviclin (p=0.853), was associated with mortality) (see table 4).

PR GLM link log and family binomial; PRa GLM link log and family poisson, adjusted by age group, HSPI level, at least one mistake in triage and dengue severity
The study's results indicate a high frequency of diagnostic and initial management errors in the pre-hospital and hospital phases. In both triage and the healthcare center, 9/10 treated patients experienced at least one error or omission during the process; in observation/Uviclin, this error occurred in 5/10 patients. Similarly, in the healthcare center (4/10) and in triage (3/10), patients were incorrectly classified based on their severity, which improved under observation. Only 2/10 patients in triage and 4/10 patients in the healthcare center, respectively, received adequate hydration.
The results may show bias in healthcare staff documentation because they may not have enough time to record every detail. Another possibility is a lack of standardized formats set up by the new National Technical Standard (5). This reality is often evident in scenarios of patient overload, epidemics, and care provided by front-line personnel with limited experience. A recent example was the COVID-19 pandemic, which made this type of inconvenience clear (14). On the other hand, a lack of adherence to the CPG recommendations is common not only in our country but in other realities and infectious pathologies such as COVID-19 (15).
Evidence suggests that the region has conducted training. Experts conducted four training sessions between 2023 and 2024: the first for 150 primary care health professionals (16), and the second for personnel with similar characteristics in the Morropon-Huancabamba Health Sub-Region (17). The Regional Directorate of Health Piura trained more than 1,200 nurses from the Ministry of Health (MINSA), Social Security (Essalud), Police Forces Health Facilities (Sanidad), and other healthcare establishments in a 12-hour workshop course in October 2023 (18, 19). However, it is crucial for any strategy to not only provide training for the personnel in charge but also to measure the baseline (knowledge, attitudes, and practices) (8)
(10) and determine the impact afterwards. In this scenario, quasi-experimental studies are an attractive model and an especially useful tool (20).
In an 18-month study in India by Balkrishnan et al., in patients with DWS, pre- and post-intervention measurements were carried out, determining that the educational program had an impact on improving the admission and classification criteria, monitoring of vital signs, correct use of bolus fluids, fluid therapy in titration, hematocrit monitoring, platelet transfusion when indicated, and discharge criteria. Also, mortality decreased from 7.1% to zero. The median hospital stays decreased by one day (21). An attractive possibility is to describe the before and after evaluations conducted on doctors in Piura in 2023 (19). Qualitative research is another unexplored scenario that is potentially helpful in exploring the perceptions, attitudes, and
limitations of human resources. Quantitative measurement of adherence to a guideline is insufficient to explore these scenarios (22).
The Peruvian Health Ministry Directorate for the Prevention and Control of Metaxenic and Zoonotic Diseases developed a strategy to measure adherence to the National Technical Standard's recommendations (5). According to their findings, in Peru, adherence was 70.5% (249 evaluations), with 51.27% in treatment and 73.76% in diagnosis. After reviewing 33 records, global adherence was 68.22% in Piura, 73.74% in diagnosis, and 49.19% in treatment, ranking ninth out of 13 regions (23).
These figures are more encouraging; however, the evaluation of compliance should focus on the correct completion of forms and sociodemographic data rather than clinical aspects. We believe that our results can provide input for metaxenic strategies and other managers looking to improve training, infrastructure, and political commitment to addressing dengue. In the case of the Peruvian Social Security Health System (ESSALUD), 42 clinical records as of March 2024 from cities Piura, Lambayeque, La Libertad, Ancash, and Ica, were audited. It was found that the frequencies of notification to epidemiology surveillance, recording of the date of onset of symptoms, observation/hospitalization, parenteral hydration, recording of vital functions, and request for at least one blood count were 62%, 83%, 83%, 76%, 71%, and 91%, respectively (24). The National Health Ministry Health System made similar observations.
Even in patients with DWS, the high mortality rate of 18% is striking. Other probable causes include related comorbidities (which were not measured in this study) and limitations in diagnosis and case management. In a recent systematic review of our country, out of 17 publications between 1993 and 2023, including 10 regions of Peru and 2310 patients, mortality was 1.73% (25). The significant variation in mortality could potentially be attributed to our study's bias, as we exclusively included patients from Piura, our non-random sampling method, and the severity of our patients (20.7% of those who had severe dengue). However, in the exploratory multivariable analysis, the presence of at least one error in the hospital and in the health center, was not ultimately associated with mortality. This could be attributed to biases in the sample size (140/158) and sample design (consecutive), as well as the challenges of applying a retrospective checklist, which, despite training, may have measurement biases. Only dengue severity and age over 18 years, were associated with higher mortality.
There has been serious criticism of the efficiency of the reference and counter-reference systems in Peru. The referral process took more than 2 hours for more than 60% of patients (26). According to
the regional government, the hospital where the study took place has approved the formation of a counter-referral team, but its implementation is still under development (27). Meanwhile, over 30% stayed in triage for over four hours. Understaffing and insufficient areas of attention are possible explanations. The current National Technical Standard mandates that in DWS, medical care should begin in less than 30 minutes, with immediate intravenous hydration; in SD, immediate attention is needed (5). This study has found many challenges in implementing these measures.
Regarding the observation/Uviclin area's findings (55% of "at least one error"), we could attribute these findings to time constraints, patient overload, burnout, unnecessary form filling (National Insurance/discharge procedures), and possibly a lack of organization. This area requires monitoring with practical protocols. It is also imperative to verify the proper operation of equipment and supplies.
Theoretically, hospitalized first-level health care facilities (I-3 and I-4) can handle dengue diagnosis and alarm signs by providing an immediate response based on hydration and vital sign monitoring (blood pressure, heart rate, respiratory rate, temperature, oxygen saturation, water and electrolyte balance, etc.), which forms the foundation of effective dengue management. These facilities typically have a basic laboratory that works between 12 and 24 hours for monitoring with a complete blood count, although dengue management is still clinical in the Americas, according to the WHO (28). Again, human resource training (3, 4), as well as a lack of clear and socialized processes, could explain this reality.
One of the study's limitations was that it did not meet the required sample size (n = 159 medical
records). Some of the reasons for this were the inability to find the clinical history, incomplete data in the follow-up, and a lack of digitization of data and processes. However, the limitations prevented a random sampling process. Likewise, the 2023 cases were limited to weeks 18–25 (the peak of the outbreak). However, we believe that these results can serve to support any effort in the implementation of the electronic health record to improve information management (29)(30). The Ministry of Health and the regional governments still have unresolved issues.
We firmly believe that there are various actions that the Government in alliance with universities, should apply to improve the processes of care for Dengue cases:
1. Improvement of information systems, which implies improving the infrastructure and interoperability of the systems that results in adequate registration of data and an improvement in health management.
2. Clarification and socialization of care processes in institutions and in reference and counter-reference processes between institutions.
3. Training through action-participation methodologies to achieve the involvement of administrative and clinical actors, evaluating the system's response before and after the interventions.
4. Commitment of the universities of the Piura region from undergraduate, postgraduate and specialization to generate joint work with the strategies of the Ministry of Health in the care of patients with dengue
In conclusion, we found a high frequency of errors in the diagnosis of severity and in the treatment of patients with DWS and SD in the pre-hospital and hospital phases, but the sample size was insufficient to determine whether this finding had an impact on mortality.
