Précis: This debate article highlights some questions from critics of qualitative research. Planning for proper design, philosophical background, researcher as a research instrument in the study, trustworthiness and application of findings are main debates in this field. One of the issues that have been received little attention is report of qualitative inquiry. A qualified report can answer the critics. This requires that the qualitative articles cover all points about the selected method and rigourness of study conduct to convince policy makers, managers and all readers in different level.

Background: As the largest and most fundamental group targeted by programs developed to improve quality of care, nurses should be the focus of attention in the management of human resources in the field of health care. A review of literature on this subject revealed the lack of scales designed for measuring professional commitment in nurses. The present study was designed to develop a scale to measure professional commitment in clinical nurses and examine its psychometric properties.
   Methods: This study will develop a professional commitment scale for clinical nurses within one qualitative and one quantitative step. The first step of the study will entail a review of the literature on the subject and interviews with clinical nurses so as to develop the categories and the items. The second step, the quantitative step, will analyze the items extracted in the qualitative step, determining the features of the topics and factor structure of the scale. The initial scale will be completed by 300 clinical nurses. The correlation among the topics, the construct validity, and reliability of the scale will also be examined in this step.
   Results and Discussion: This study will develop an instrument that can measure professional commitment in clinical nurses. Given the lack of instruments for measuring professional commitment in clinical nurses, the findings of this study may be of help to nursing managers, authorities, and the health system in general.

Background: Promotion of nurses’ professional commitment is one of the strategies for retaining nurses and preventing their turnover. The aim of this study was the development and psychometric testing of the Nurses’ Professional Commitment Inventory.
   Methods: This mixed method study was performed in an item generation and a psychometric testing phase. In the first phase, a 34-item inventory was developed based on the results of a grounded theory and the existing literature. Search date was 2010 to May 2018. In the second phase, we recruited 272 clinical nurses and tested the psychometric properties of the inventory. Construct validity was tested via the exploratory factor analysis. Reliability testing was performed through test-retest stability and internal consistency testing. SPSS version 21.0 (SPPS Corp) was used for statistical analysis. Significance level was set at p<0.05.
   Results: In the first phase, a 74-item pull was extracted. After reviewing, the primary version of the Nurses’ Professional Commitment Inventory (NPCI) with 34 items was developed. Eight items were deleted during psychometric testing. In factor analysis, the remaining 26 items were loaded on 3 factors, namely professional attachment, professional performance, and internalization of the profession. These factors explained 53.92% of the total variance of professional commitment. The Cronbach’s alpha and mean test-retest intraclass correlation coefficient  for NPCI were 0.92 and 0.88, respectively.
   Conclusion: The Nurses’ Professional Commitment Inventory has acceptable validity and reliability. This inventory includes dimensions that indicate the formation of professional commitment. The items of the scale can reveal nurses’ strengths and weaknesses related to professional commitment.

Background: Predicting the outcome of blunt chest trauma by scoring systems is of utmost value.
We aimed to assess the role of the chest trauma scoring system (CTS) in predicting blunt chest trauma outcomes among Egyptians.
   Methods: A prospective observational study included 45 patients admitted to the cardiothoracic emergency unit of Al-Azhar University hospitals. We documented their demographic data, history, cause and mode of trauma, vital parameters, and necessary investigations (e.g., chest X-ray and Computed Tomography) when the patient was admitted to the cardiothoracic department. All patients were assessed using the chest trauma scale (CTS) and followed up till death or discharge.   
   Results: The patient's age ranged between 18 to 76 years (mean 42.67 years). Eighty percent were males, and 48% needed mechanical ventilation (MV). The period of MV was ranged from 1 to 5 days (mean 2.81 days). Twenty-two patients had pneumonia. Eight patients died with a chest trauma scale ranging from 2 to 12 with a median of 6. About 87 percent of patients had unilateral lesions, and 5 had criminal causes. Road traffic accidents were the most typical cause of trauma (60%). There was a significant relation between mortality among the studied patients and each MV, length of ICU duration, chest trauma scale, laterality of trauma, and associated injuries. There was a statistically significant relation between the chest trauma scale and the need for MV, the timing of MV, the presence of pneumonia, and mortality.
   Conclusion: CTS ≥ 6.5 can predict mortality with 100.0% sensitivity, specificity of 62.2%, and accuracy of 68.9%. However, a score of ≥ 5.5 can predict the development of pneumonia with a sensitivity of 81.8%, specificity of 78.3%, and accuracy of 80%.

Background: Pectus excavatum is the most frequent congenital defect of the chest wall. Surgical treatment with modified Ravitch-type repair is recommended in patients with cosmetic dissatisfaction or considerable cardiopulmonary symptoms.  We aimed to analyze the surgical, aesthetic, cardiopulmonary functions and patient satisfaction outcomes of modified Ravitch repair pre and postoperatively.
   Methods: This was a prospective analysis of 13 pectus excavatum patients undergoing repair by modified Ravitch using a permanent titanium plate fixed with a screw from September 2021 to August 2023. Patients were included  to relieve pressure on the heart and lungs if complaining of exercise intolerance, cosmetic impairment, shortness of breathing, chest pain, or psychological disturbance with an age range from 10 years to 30 years old. While patients who had received conservative or surgical treatment previously or patients with scoliosis, Marfan syndrome or bronchial asthma were excluded. At the 6-month postoperative visit, a postoperative satisfaction survey was conducted.
   Results: The means of the age of patients (16.4 ± 2.36 years); operative duration (120 minutes); blood loss (200± 15.47 mL) and Haller index was (3.8± 0.35)  preoperatively compared with less than 3.0 (2.7± 0.08  postoperatively; hospital stay (7 days). The most frequent complications were seroma in one patient (7.69%), postoperative bleeding in one patient (7.69%) and skin infection in one patient (7.69%) of patients. No recorded infection of the sternal plate or required operative re-exploration for infection. All patients were subjectively satisfied with the excellent surgical results. Exercise intolerance despite increased exercise performance was observed following surgery, including less sensation of dyspnea.
   Conclusion: Modified Ravitch-type repair is a secure and reliable method for treating pectus excavatum with better relief of preoperative symptoms.
