概括
诊断代码可以准确地识别患有平 (LP) 和平 (LPP) 的患者,用于人口研究. 通过医生专业限制代码进一步提高了这些病例发现策略的准确性.
科学领域:
- 皮肤病学 皮肤病学
- 流行病学 流行病学
- 医疗信息学 医疗信息学
背景情况:
- 基于人群对平坦 (LP) 和平坦 (LPP) 的研究缺乏确定的病例识别策略.
- 准确的病例鉴定对于流行病学研究和了解疾病负担至关重要.
研究的目的:
- 评估使用诊断代码用于确定皮肤 (非口腔) LP和LPP队列的有效性.
- 确定不同基于诊断代码的病例定义的正预测值 (PPV).
主要方法:
- 对LP和LPP的ICD-9/ICD-10代码的患者进行了回顾性图表审查.
- 根据医生的专业 (任何医生与皮肤科医生) 对病例确认的评估.
- 对各种案例定义 (例如,一个代码,两个代码) 的PPV计算.
主要成果:
- 当皮肤科医生应用代码时,观察到"任何LP" (高达95.1%) 和LPP (高达96.2%) 的高PPV.
- 非口服LP的PPV有所不同,最高的PPV (86.3%) 是使用皮肤科医生指定的一个代码实现的.
- 使用诊断代码,特别是由皮肤科医生分配的代码,在识别确认的LP和LPP病例方面表现出很高的准确性.
结论:
- 诊断代码,特别是当被诊断医生的专业限制时,可以可靠地识别LP,非口腔LP和LPP的病例队列.
- 这些发现支持使用诊断代码作为在流行病学研究的大型临床数据库中确定病例的有效策略.
- 该研究为未来对LP和LPP的基于人口的研究提供了验证的方法.

Documentation of Nursing Diagnosis
1.3K
The nurse documents nursing diagnoses and enters them into the patient record. The identified patient's nursing diagnosis is either written out with a plan of care or entered into the electronic health record.
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters...

Formulating and Validating Nursing Diagnosis I
2.7K
A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.
