まとめ
国際疾病分類 (ICD) のコードでは,HIV感染者 (PWH) の入院理由が一般的に記載されています. しかし,HIVがコントロールされていないPWHや,複雑な入院期間があるPWHについては,判断が必要である.
科学分野:
- 医療情報工学 医療情報工学
- 公衆衛生は公衆衛生である.
- 感染症疫学 感染症疫学
背景:
- HIV感染者 (PWH) は高い入院率を経験しており,その理由はしばしば不明です.
- 国際疾病分類第10版,臨床修正 (ICD-10-CM) などの出院診断コードは,PWHにおける入院原因を誤って分類する可能性があります.
- 入院理由の正確な分類は,医療ニーズを理解し,PWHのアウトカムを改善するために不可欠です.
研究 の 目的:
- HIV感染者 (PWH) の入院の主な理由を表すICD-10-CMコードの正確性を評価する.
- ICDに基づく入院理由と専門家の判断を比較する.
- ICDのコーディングと専門家のレビューの間の不一致に関連した患者の特徴を特定するために.
主な方法:
- UNC CFAR Clinical Cohort Study (UCHCC) のPWHの間で2016年から2019年にかけての1428件の入院から302件の入院 (21%) のランダムサンプルが選択されました.
- ICDに基づく入院理由は,ICDに記載されている第1または第2の退院診断を用いて決定した.
- ICDに基づいた理由と専門家の判断を比較し,結果を完全合意,部分合意,意見の相違,または不適切なICDコーディングとして分類しました.
主要な成果:
- 専門家の判断は,入院の73%でICDに基づく理由と完全に一致し,14%では部分的な同意,8%では意見の相違,6%では不適切なコーディングと一致しました.
- 患者による合意の低さに関連する要因には,最近のCD4カウント <200細胞/mm3,最低CD4カウント <50細胞/mm3,出院診断 ≥15,滞在期間 ≥4日,主要な診断としてHIVが含まれています.
- 研究対象は204人のPWH (69%男性) で,平均年齢は51歳,入院時のCD4細胞数の平均値は539細胞/mm3でした.
結論:
- ICD-10-CMコードは,HIV感染者 (PWH) の大半の症例において,入院の理由を効果的に把握しています.
- 専門家の判断は,HIVが制御不良 (例えば,低CD4カウント) と複雑な入院を含む特定の患者のサブグループに推奨されます.
- 洗練されたコーディング・プラクティスとターゲティングされた判断は,PWHの入院データの正確性を向上させ,より良い医療管理と研究を支援することができます.

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Hospitals-II

Hospitals provide inpatient and outpatient services. Inpatient services provide care to patients that stay in the hospital for an extended period, ranging from days to months. Examples of inpatient services include intensive care units, hospital wards, or surgeries. Outpatient services provide care to patients who come to a hospital for a diagnostic or treatment but do not stay overnight —for example, diagnostic tests, surgical procedures, or health education.

Hospitals offer medical and surgical care to the sick and injured, along with accommodation while they recover. At the same time, they also provide outpatient, emergency, psychiatric, and rehabilitation services to meet various community needs. In addition to providing medical care, hospitals also act as hubs for medical research and training. Hospitals use clinical procedures and evidence-based practice standards to deliver patient care. To deliver safe and efficient care, a nurse must stay up...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Pulmonary Tuberculosis I
1.0K
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
