If these tests can detect the presence of MRSA and show that MRSA non-infected persons are correctly MRSA negative, the number of affected persons who need to be managed individually can be reduced, preventing infection. The cost of measures can be reduced. From this point of view, negative predictive value is important for MRSA infection.
- test terminal Make a presentation that recommends that you
- the test terminal does not recommend this test but recommends that another more sensitive test method be performed Make a presentation or make a presentation that recommends individual management of the patient without examination.
- the negative predictive value will be 90% or more, so the execution of the test is recommended. If the prevalence exceeds 50%, the negative predictive value will be less than 90%, so we do not recommend running the test, recommend another more sensitive test method, or It is recommended to carry out individual management.
- the negative predictive value is 90% or more when the prevalence rate is 66.7% or less, so a test is recommended. If the prevalence rate is higher than 66.7%, the negative predictive value will be less than 90%, so we do not recommend the test, recommend another more sensitive test method, or individually manage the patient Recommend.
- sensitivity, specificity, prevalence and negative predictive value have a predetermined relationship. Therefore, it is understood that when the prevalence rate is 30% and the negative predictive value is 90% or more, a test method with a sensitivity of 77% and a specificity of 90% or more may be used.
- the examination terminal recommends the doctor as follows to the examination method to be performed. That is, when the prevalence rate is 30%, it is recommended to use an immunochromato kit which has low sensitivity but low cost, and when the prevalence rate is 50%, a high cost but high sensitivity genetic testing kit and testing time It is possible to recommend a long but sensitive culture test.
- the examination system a list of examination methods that can be performed by the medical institution performing the examination is maintained, and a doctor is asked for the optimum examination method based on the sensitivity, specificity, prevalence, and negative predictive value. It may be recommended.

- Example 1 of prevalence rate of influenza virus Next, we will explain how the prevalence of influenza virus fluctuates depending on the time of day and the region. Here, we use materials from the Tokyo Metropolitan Institute for Health and Safety Research. This data is the yearly and yearly number of influenza patients per fixed point.
- influenza virus tends to be low in June and July, while it is usually high in February and March.
- the onset of the epidemic differs from year to year, and its prevalence also differs significantly.
- the pandemic strain (H1pdm) that became prevalent in 2009, the prevalence may be high in October, November, and December when it does not occur every year.
- IASR National Institute of Infectious Diseases Pathogenic Microorganisms Detection Information
- Example 2 of the prevalence of influenza virus
- This material represents the estimated number of visits by age group in the infectious disease outbreak trend survey of the Ministry of Health, Labor and Welfare.
- the prevalence of influenza virus at ages 0-14, especially 5-9 tends to be higher compared to other age classes. That is, it can be seen that the prevalence rate changes significantly depending on the age class.
- the prevalence varies depending on the community to which the patient belongs. For example, there is a reported example that “prevalence of influenza virus in the 2012-2013 season” reported by Nara Koriyama Public Health Center has a high prevalence of influenza virus in lower grade primary school children. For example, there is a reported example that the prevalence of primary school children in a certain elementary school in the 2011-2012 season was 30% or more.
- the prevalence of influenza virus like in the 2011-2012 season in Japan is estimated to be 16.48 million. From the results of the 2010 census, assuming that the population of Japan is 128 million people, the prevalence rate of influenza virus is 12.9% at the highest level, which is different from the example of Nara Prefecture. That is, it has been suggested that the prevalence of influenza virus varies depending on the community.

Abstract
Description
また、有病率の精度を向上させる為には、検査結果の総数が非常に多いことが重要であるが、これまでの検査システムでは、総数を増やすことには主眼が置かれていなかった。
臨床現場において用いられる検査機器や検査薬、検査キット(以下、まとめて検査機器と呼ぶ)には、検査機器が罹患患者を正しく陽性と判定できる精度(=感度)と、非罹患者を正しく陰性と判定できる精度(=特異度)が定義されている。これらの精度は、検査機器の製造時に特定できるものである。これまで、臨床検査では、これらの指標を参考にして、検査結果に対する医師の最終判断が行われてきた。
ここで、有病率および有病率に関連する指標について、簡単に説明する。図1は、ある疾患の臨床検査を、ある検査方法により行った際の状態を表している。ここで、検査機器により陽性という結果が出て、かつ医師が確かにその患者が疾患に罹患していると最終判断を下したケース(真陽性)に該当する人数をa人としている。また、検査機器により陽性という結果が出たが、医師によりその患者はその疾患に罹患していないという最終判断を下したケース(偽陽性)に該当する人数をc人としている。
次に、有病率と陽性的中率、陰性的中率の関係について説明する。
まず、ベイズの定理により、ある検査を患者に対して行って、実際に罹患している確率(オッズ)は、その検査を行う前に、その検査で陽性になる検査前オッズと尤度比を用いて、以下の数式(1)のように表される。
検査前オッズ=有病率/(1-有病率) (7)
検査陽性後オッズ=陽性的中率/(1-陽性的中率) (8)
検査陰性後オッズ=陰性的中率/(1-陰性的中率) (9)
陽性尤度比=感度/(1-特異度)
=(真陽性数/疾患数)/(偽陽性数/非疾患数) (10)
陰性尤度比=(1-感度)/特異度
=(偽陰性数/疾患数)/(真陰性数/非疾患数) (11)
陰性的中率=特異度×(1-有病率)/(特異度×(1-有病率)+有病率×(1-感度)) (13)
次に、陽性的中率、陰性的中率に基づく治療方針の提示について説明する。ここでは、上述した検査端末において、計算された陽性的中率および陰性的中率に基づいて、検査後に次に採るべき検査方針および治療方針について提示する構成を説明する。

次に、薬剤耐性菌の有病率が、地域(国)により変化する様子を説明する。ここでの説明は、European Antimicrobial Resistance Surveillance System (EARSS)のEuro Surveillance 2008 Nov 20 Volume 13, Issue 47の資料に基づいている。この資料は、ヨーロッパにおける国別の薬剤耐性菌の有病率を示したものである。
次に、インフルエンザウイルスの有病率が、時期や地域によって変動する様子を説明する。ここでは、東京都健康安全研究センターの資料を用いる。この資料は、定点あたりのインフルエンザの患者数を時期ごとおよび年ごとに表したものである。
次に、インフルエンザウイルスの有病率が、患者の年齢や所属するコミュニティによって変動する様子を説明する。ここでは厚生労働省と奈良県郡山保健所の資料を用いて説明する。この資料は、厚生労働省の感染症発生動向調査における、年齢階級別の推計受診者数を表したものである。

陰性的中率=特異度×(1-有病率)/(特異度×(1-有病率)+有病率×(1-感度)) (13)
なお、陽性的中率および陰性的中率は、有病率を用いずに、それぞれ直接、式a/(a+c)およびd/(b+d)から求めてもよい。
次に、上述した有病率を集計し算出する処理の詳細について説明する。図8は、有病率を集計し算出する処理の詳細について説明するフローチャートである。
次に、上述した検査の実施について詳細を説明する。図9は、検査の実施について詳細を説明するフローチャートである。
上記の説明では、検査端末20が、その検査端末自身の感度および特異度の情報を持っており、検査サーバ40からは有病率のみをダウンロードして、検査端末20側で、陽性的中率および陰性的中率を計算する処理を説明した。
上記の説明では、検査サーバ40から検査端末20に、有病率のみ、または、有病率、陽性的中率、および陰性的中率の3つをダウンロードする構成とした。これに対し、ここで説明する変形例では、より多くの情報をダウンロードし、ユーザに提示してもよい。例えば、診断総件数や疾患件数などである。これらもユーザに提示することにより、算出された陽性的中率および陰性的中率の妥当性を判断することが出来る。
上記の説明では、感度および特異度は、検査機器28において一意に決定されるものとした。これに対し、ここで説明する変形例では、感染症などの病気を発病してからの経過時間によって、感度および特異度を変化させる構成について説明する。
上記の説明では、疾患の検査として、1つの検査を実行する構成を説明した。これに対し、ここで説明する変形例では、複数種類の検査を実行し、それらの結果を総合して最終的な検査結果(最終的な診断結果ではない)を出力する構成を説明する。この変形例の構成では、複数種類の検査を行い、すべての検査で陽性となった場合のみ最終的な検査結果を陽性としてもよい。これにより、尤度(感度および特異度)の精度を向上させることが出来、最終的に算出される陽性的中率および陰性的中率の精度も向上させることが出来る。
上記の、複数の検査を組み合わせる変形例では、全ての検査を行った後に、全ての検査結果を統合して処理する構成を説明した。これに対し、ここで説明する変形例では、複数の検査を1つずつ実行し、1つの検査結果が出るたびに、検査を続行するか否かを判断する。この変形例では、段階的に検査を行うことにより、有病率に基づいた最終的な診断結果の精度を向上させることが出来る。
上記の説明では、データベース47aに格納している全てのレコード、すなわち全ての検査結果を対象として、有病率を集計し算出した。これに対し、ここで説明する変形例では、検査端末20の属性(端末属性情報)に基づいて、有病率の集計と算出の基となる検査結果を絞り込む構成を説明する。
上記の絞り込みを行う変形例では、検査端末20の属性に基づいて、有病率の集計と算出の基となる検査結果を絞り込む構成を説明した。これに対し、ここで説明する変形例では、検査端末20の属性に代わり、検査を受ける患者の属性(患者属性情報)に基づいて、有病率の集計と算出の基となる検査結果を絞り込む構成を説明する。
上記の絞り込みを行う変形例では、検査端末20の属性や患者の属性を用いて絞り込みを行った。これに対し、ここで説明する変形例では、絞り込みを行った結果、対象とする検査結果の数が不足し、検査結果の集計からは意味のある有病率を導き出せない場合の解決策の1つを説明する。
上記の説明では、有病率を求めるための集計を行う際に、1つの検査結果の重みを1としてカウントする(単純に陽性の件数をカウントする)構成について説明した。これに対し、ここで説明する変形例では、検査が行われた環境の条件(例えば、特定地域での予防接種普及率)を考慮して、カウントアップした陽性の件数に重み付けを行って補正し、真の有病率を予測する構成を説明する。なお、重み付けは、例えば、所定の条件に応じて係数を乗じることにより行う。
上記の説明では、有病率を算出するために、過去の検査結果においては、必ず医師の診断結果も得られることを前提としていた。これに対し、ここで説明する変形例では、検査端末20による検査の際に医師による最終的な診断結果の入力がなされないことがあるという前提に立つ。医師による最終的な診断結果が入力されないことがあると、データベース47aの「診断結果」欄に空白のものが発生し、集計して求める有病率の精度が低くなってしまう。そのため、本変形例では、有病率の代わりに、有病率の代用となる近似的な指標を用いる。
ここでは、有病率を陽性率の関係が、感度および特異度により変化することについて説明する。
上記の、有病率を陽性率で代用する変形例では、ある検査方法に対する有病率の代わりに、その検査方法出られる陽性率を用いた。これに対し、この変形例では、上述した、有病率を陽性率で代替する場合、より高感度、高特異度の診断機器に基づく陽性率を用いたほうが、本来の有病率から算出される陽性的中率、陰性的中率により近くなるという点を考慮する。なお、ここでいうより高感度、高特異度とは、信用するに足るほど充分に大きいという意味であり、別の言い方をすれば、予め要求される所定の値を満足するということである。
陰性的中率=特異度i×(1-陽性率p)/(特異度i×(1-陽性率p)+陽性率p×(1-感度i)) (17)
次に、CPU41は、有病率を陽性率で代替する(ステップS17e)。有病率の値は、より高精度な検査方法に基づく陽性率で代替され、以降の処理で利用される。
上記の構成では、検査を行う医師に対し、検査端末20が有病率、陽性的中率、および陰性的中率、すなわち医師が最終的な診断を行うにあたり参考となる情報の表示を行った。それに対し、ここで説明する変形例では、検査端末20が、例えば、算出した陽性的中率が現実的な値か否かを判断し(有効性を評価し)、現実的(有効)であれば、医師に検査の実施を推奨する。
上記の説明では、検査を実施する地域における過去の検査結果を集計することにより、その地域における有病率を算出した。これに対し、ここで説明する変形例では、これまで検査を実施していない地域の有病率を、他の地域で算出された有病率から推測する。
なお、ここでは、ある地域の有病率は、他の地域からの距離の2乗に反比例すると仮定したが、これ以外に、感染に影響を与える要因、すなわち、都市間の交通状況や地形を加味した距離、測定時刻、人口密度、および医療レベルのうち少なくとも一つに基づいて重みづけ補正を行ってもよい。
上記の説明では、検査システム10は、現時点での有病率を提供した。これに対し、ここで説明する変形例では、現時点での有病率に加え、今後の予測有病率も提供する。なお、今後の予測有病率を提供するための処理は、検査サーバ40において行われてもいし、検査端末20において行われてもよいし、両者の間で分担する形で処理が行われてもよい。ここでは、検査サーバ40において処理が行われるものとして説明を行う。
(a)現時点の有病率や一定時間前の有病率として、より細かい時間単位(例えば1時間ごと)で取得した複数の有病率の平均を用いる。
(b)より短い時間単位での変化率を求め、それらの変化率の平均を取る。
上記の説明では、検査端末20側で検査を行う度に検査サーバ40から有病率などの情報をダウンロードする構成を説明した。これに対し、この変形例では、検査サーバ40の負荷を減らし、検査サーバ40および検査端末20間の通信料を削減するために、有病率などダウンロードした情報を検査端末20上でキャッシュする。検査端末20は、検査の度に有病率などの情報を検査サーバ40に要求するのではなく、一定時間の間は、検査端末20にキャッシュされた有病率などの情報を利用する。
上記の説明では、最終的な診断結果等は、医師が検査端末20に入力し、検査端末20が検査サーバ40にアップロードする構成を説明した。これに対し、ここで説明する変形例では、病院内のLIS(Laboratory Information System)などのローカルシステムや、インターネット上のクラウドシステムを介して、診断結果等の情報を検査サーバ40にアップロードする構成を説明する。
上記の説明では、検査端末20において、医師などのユーザに対し、算出された有病率や陽性的中率、陰性的中率などの提示を行う構成を説明した。これに対し、ここで説明する変形例では、検査端末20が、ユーザに対し、投薬の推奨を行う。
上記の説明では、検査端末20の表示部26上に、一般的な有病率や、属性による絞り込みを行った結果の有病率、重み付けを行った結果の有病率、有病率の代用となる陽性率、検査実施/不実施の推奨、予測有病率、投薬の推奨、患者の個別管理の推奨などの表示を行う構成について個別に説明した。これに対し、ここで説明する変形例では、これらの表示を統合して行う構成などについて説明する。
上記の説明では、検査システム10がクライアント・サーバ構成を採り、クライアントである検査端末20とサーバである検査サーバ40とが、分担して処理を行う構成を説明した。これに対し、ここで説明する変形例では、検査端末20が行う処理を必要最低限のものに限定し、殆どの処理を検査サーバ40で行う変形例について説明する。
ここでは、本技術に係る検査システム10、検査サーバ40、および検査端末20の構成と機能の概略についてまとめる。
本実施形態の検査システム10により、例えば、以下の様な効果を得ることが出来る。
(1)多数の検査端末20から得られた情報に基づき、有病率等、診断の指標となる情報を提供することにより、医師が下す最終的な診断結果の精度を向上させることが出来る。
(2)データベース47aに蓄積された情報に対して絞り込みや重み付けを行って、有病率等、提供する情報の精度をさら高めることが出来る。
(3)検査システム10内には無い情報を外部から取得することにより、有病率などに加えて、さらに有用な情報を医師に提供することが出来る。
(4)検査サーバ40側を変更するだけで、新規機能に基づく新しい情報を医師に提供することが出来る。
(5)典型的な検査システムとは異なり、即時性をもって感染症などに対応することが出来る。
その他、本技術は、上述の実施形態にのみ限定されるものではなく、本技術の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
