9 (CASP) - Critical Appraisal Skills Programme Screening Questions
1.Did the review ask a clearly-focused question? (明確的重點問題) Yes Patient / Problems :Impact of contact and droplet precautions on the incidence of hospital-acquired methicillinresistant Staphylococcus aureus infection. Intervention:contact precaution Comparison:contact and droplet precautions Outcome:The implementation of contact precautions significantly decreased the rate of hospital-acquired MRSA infection 2.Did the review include the right type of study? (正確類型的研究) To identify inpatients infected or colonized with MRSA (prospective study )

10 (CASP) - Detailed Questions-1
3.Did the reviewers try to identify all relevant studies? (試圖找出所有相關的研究) Yes 4.Did the reviewers assess the quality of the included studies? (評估納入研究的質量) 5.If the results of the studies have been combined, was it reasonable to do so? (研究的結果，已被合併，這樣做是否合理)

11 (CASP) - Detailed Questions-2 6
(CASP) - Detailed Questions How are the results presented and what is the main result? (提出和主要結果是什麼) The implementation of contact precautions significantly decreased the rate of hospital-acquired MRSA infection, and discontinuation of droplet precautions in the ICUs led to a further reduction.

13 (CASP) - Detailed Questions-3 7. How precise are these results? 這些結果精確
Following the implementation of contact and droplet precautions, combined rates of hospital-acquired MRSA infectionin the MICU and SICU decreased to 4.3 infections per 1,000 patient-days

14 (CASP) - Detailed Questions- 4
8. Can the results be applied to the local population? 結果可否被運用在當地人口對象 Yes 9. Were all important outcomes considered?重要的結果都被考慮

15 文獻結論 在高感染率的加護病房裡，採接觸和飛沫防護措施可顯著的下降院內MRSA感染率，但在低感染率的加護病房裡，感染率維持不變。
高感染區域僅採取接觸防護措施即可顯著降低院內MRSA感染率，這顯示出接觸防護措施在預防院內感染MRSA扮演重要的角色。
