Abstract

OBJECTIVE: To establish the incidence and aetiology of infectious intestinal disease in the community and presenting to general practitioners. Comparison with incidence and aetiology of cases reaching national laboratory based surveillance. DESIGN: Population based community cohort incidence study, general practice based incidence studies, and case linkage to national laboratory surveillance. SETTING: 70 general practices throughout England. PARTICIPANTS: 459 975 patients served by the practices. Community surveillance of 9776 randomly selected patients. MAIN OUTCOME MEASURES: Incidence of infectious intestinal disease in community and reported to general practice. RESULTS: 781 cases were identified in the community cohort, giving an incidence of 19.4/100 person years (95% confidence interval 18.1 to 20.8). 8770 cases presented to general practice (3.3/100 person years (2.94 to 3.75)). One case was reported to national surveillance for every 1.4 laboratory identifications, 6.2 stools sent for laboratory investigation, 23 cases presenting to general practice, and 136 community cases. The ratio of cases in the community to cases reaching national surveillance was lower for bacterial pathogens (salmonella 3.2:1, campylobacter 7.6:1) than for viruses (rotavirus 35:1, small round structured viruses 1562:1). There were many cases for which no organism was identified. CONCLUSIONS: Infectious intestinal disease occurs in 1 in 5 people each year, of whom 1 in 6 presents to a general practitioner. The proportion of cases not recorded by national laboratory surveillance is large and varies widely by microorganism. Ways of supplementing the national laboratory surveillance system for infectious intestinal diseases should be considered.

  • There are unresolved methodological issues within population-based studies, including recall period selection and recall bias.

    “However, there are still unresolved methodological issues within population-based studies, including recall period selection and recall bias [17, 19, 20].”

    From Burden of acute gastrointestinal illness in the Metropolitan region, Chile, 2008 (2011) · cites this paper as [17]

    The Community rates section identifies recall bias as a probable reason retrospective estimates were higher than prospective estimates. The Community cohort section specifies a one-month recall period, but the paper does not discuss recall-period selection as an unresolved methodological issue. (LLM, conf=0.86)

  • The overall range of annual incidence rates of 0.98-2.3 episodes per person-year in this study is higher than those reported in Ireland, the UK and The Netherlands.

    “The overall range of annual incidence rates of 0 . 98-2 . 3 episodes per person-year in our study are higher than those reported in Ireland, the UK and The Netherlands [14, 17, 24].”
  • Retrospective methods may be more subject to recall bias and thus under ideal conditions, prospective methodology is preferred.

    “Retrospective methods may be more subject to recall bias and thus under ideal conditions, prospective methodology is preferred [17].”
  • The current study's result is contrary to the suggestion that 'telescoping' past illnesses into the observation period causes overestimates of disease in the population when using retrospective methods.

    “However, this is contrary to the suggestion that 'telescoping' past illnesses into the observation period causes overestimates of disease in the population when using retrospective methods, as suggested by Wheeler et al . [17].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
