Acute gastroenteritis in primary care: a longitudinal study in the Swiss Sentinel Surveillance Network, Sentinella

Abstract

PurposeAcute gastroenteritis (AG) leads to considerable burden of disease, health care costs and socio-economic impact worldwide. We assessed the frequency of medical consultations and work absenteeism due to AG at primary care level, and physicians’ case management using the Swiss Sentinel Surveillance Network “Sentinella”.MethodsDuring the 1-year, longitudinal study in 2014, 172 physicians participating in “Sentinella” reported consultations due to AG including information on clinical presentation, stool diagnostics, treatment, and work absenteeism.ResultsAn incidence of 2146 first consultations due to AG at primary care level per 100,000 inhabitants in Switzerland was calculated for 2014 based on reported 3.9 thousand cases. Physicians classified patients’ general condition at first consultation with a median score of 7 (1 = poor, 10 = good). The majority (92%) of patients received dietary recommendations and/or medical prescriptions; antibiotics were prescribed in 8.5%. Stool testing was initiated in 12.3% of cases; more frequently in patients reporting recent travel. Among employees (15–64 years), 86.3% were on sick leave. Median duration of sick leave was 4 days.ConclusionsThe burden of AG in primary care is high and comparable with that of influenza-like illness (ILI) in Switzerland. Work absenteeism is substantial, leading to considerable socio-economic impact. Mandatory infectious disease surveillance underestimates the burden of AG considering that stool testing is not conducted routinely. While a national strategy to reduce the burden of ILI exists, similar comprehensive prevention efforts should be considered for AG.Electronic supplementary materialThe online version of this article (doi:10.1007/s15010-017-1049-5) contains supplementary material, which is available to authorized users.

Variation in colorectal cancer testing between primary care physicians: a cross-sectional study in Switzerland

“…Since we report rates of patients who visited their PCP, we expect the proportion of colonoscopy/FOBT to be higher than among the general popula- Strengths of this study include the high adherence of PCPs in the Sentinella network, some of whom have participated in the network for over 30 years. The Network routinely collects nationwide and country representative patient data and has participated in several studies (Gnadinger et al 2017;Hurlimann et al 2015;Schmutz et al 2017), so Sentinella physicians are practiced in providing quality data. The data collection form was developed and tested with PCPs, and was based on a comprehensible algorithm that limited the amount of data PCPs needed to collect, and standardized data collection between PCPs.…”

Challenges in Infection Epidemiology: On the Underreporting of Norovirus Gastroenteritis Cases in Germany

“…A more precise proportion could be estimated by an epidemiologically based survey of general practitioners on their diagnostic and billing behavior. The results of a longitudinal study from Switzerland show that GPs do not routinely obtain laboratory diagnostic evidence in cases of gastroenteritis [31]. Experiences within this study show, however, that such projects are not easy to conduct.…”

Prescribing Antimicrobial Drugs for Acute Gastroenteritis, Primary Care, Australia, 2013–2018

“…Of the few studies reporting on how often antimicrobial drugs are prescribed for acute gastroenteritis, estimates range from 8.5% of 2,089 cases in a sentinel surveillance sample from primary care in Switzerland in 2014 ( 12 ) to 65% in a survey of 237 physicians in China in 2012 ( 13 ). Our results were most similar to the estimates reported from the Switzerland study, which also found that antimicrobial drugs were more likely to be prescribed for older patients and those with fever ( 12 ).…”
