Abstract Objective Models for the structured delivery of care rely on organizational attributes of practice teams. The Survey of Organizational Attributes for Primary Care (SOAPC) is known to be a valid instrument to measure this aspect in the primary care setting. The aim of this study was to determine the validity of a translated and culturally adapted German version of the SOAPC. Methods The SOAPC was translated and culturally adapted according to established standards. The external validity of the German SOAPC was assessed using the German version of the Warr-Cook-Wall scale. A total of 200 practices randomly selected from a conference database were asked to participate in the validation study. Practice, clinicians and staff characteristics were determined via short-form questionnaires. We used standardized statistical procedures to reveal the psychometric properties of the SOAPC. Results A total of 54 practice teams participated by returning 297 completed questionnaires (297/425, response rate 69.8%). All four domains of the SOAPC (communication, decision making, stress/chaos, history of change) could be approved by factor analysis. Internal consistency is underlined by a Cronbach’s alpha of 0.70 or higher in all categories. We show strong correlation with the Warr-Cook-Wall scale in all corresponding categories indexing high external validity. Conclusions The German SOAPC is a reliable and valid instrument for the assessment of organizational attributes of practice teams as the providers of quality of care. Moreover, the tool makes it possible to map the state of implementation of quality management and practice organization. The availability of the German SOAPC encourages further research on this topic in German-speaking countries.

Obesity and mortality in persons with obstructive lung disease using data from the NHANES III.

South Med J. 2010 Apr;103(4):323-30

Authors: Jordan JG, Mann JR

OBJECTIVES: The objective of this study was to determine the relationship between obesity and all-cause mortality among participants with obstructive lung disease in the National Health and Nutrition Examination Survey (NHANES III). METHODS: Public data from a retrospective cohort of the 33,994 participants in NHANES III was analyzed to determine the relationship between obesity and all-cause mortality among participants with obstructive lung disease. Results were analyzed using proportional hazard models and controlled for age, sex, race, smoking status, current oral corticosteroid use, and severity of airway obstruction. Secondary analysis considered time until death from respiratory disease or time until death from chronic lower respiratory disease (excluding asthma). RESULTS: The subset used in the analysis consisted of 2439 persons with 844 documented deaths. Extreme obesity (body mass index [BMI] >40) was significantly associated with increased respiratory disease mortality (hazard ratio [HR] 5.78; 95% confidence interval {CI} [1.09 to 30.61]) and chronic lower respiratory disease mortality (HR 13.69; 95% CI [1.45 to 129.29]). In addition, underweight status (BMI <18.5) was significantly associated with increased all-cause mortality (HR 2.42; 95% CI [1.31 to 4.46]), respiratory disease mortality (HR 7.10; 95% CI [1.94 to 26.00]) and chronic lower respiratory disease mortality (HR 14.80; 95% CI [2.24 to 97.99]). CONCLUSION: Underweight adults had increased risk of death from all causes and respiratory conditions, compared to class I obese adults. Extreme obesity was associated with increased risk of death from respiratory conditions, but not all-cause mortality. Additional research is needed to explain the complex relationship between BMI and specific causes of mortality in the context of pulmonary disease.

Barriers to routine risk-score use for healthy primary care patients: survey and qualitative study.

Arch Intern Med. 2010 Apr 26;170(8):719-24

BACKGROUND: Risk scores for the primary prevention of chronic diseases in healthy adults are frequently recommended but often underused by general practitioners (GPs). The objectives of this study were to assess the use of and attitudes regarding the use of risk scores among GPs and to identify possible barriers to use. METHODS: Between November 7, 2007, and April 4, 2008, 68 GPs in Berlin, Germany, participated in the survey, and 24 were additionally invited to participate in focus groups. Quantitative data were analyzed descriptively and qualitative data were analyzed according to grounded theory. RESULTS: Survey data of 42 GPs indicated that physicians regularly perform risk assessments for healthy patients, although most did not use risk scores. The usefulness of risk scores was rated largely positive. Focus groups revealed some confusion about the definition of risk scores and that participants resisted general use. Barriers to risk-score use were lack of lifestyle recommendations, regulatory constraints, the patient’s role, and lack of accuracy. Suggestions for improvement included computerized risk prediction for multiple diseases simultaneously, better computer-generated visual presentation, and the integration of lifestyle recommendations. CONCLUSIONS: The GPs perceive the routine use of risk scores as infeasible because of regulatory constraints and the nature of the physician-patient relationship. These factors need to be considered to increase risk-score use. Training of physicians could also help somewhat to overcome underuse. Use of computerized approaches that enable the prediction of risks for several chronic diseases simultaneously and improved computer-generated visual presentation may increase acceptance. Risk profiles should further be related to recommendations for health-behavior modification.
