Identifying musculoskeletal conditions in electronic medical records: a prevalence and validation study using the Deliver Primary Healthcare Information (DELPHI) database.

BACKGROUND: Musculoskeletal (MSK) conditions are a common presentation in primary care. This study sought to determine the prevalence of MSK conditions in primary care in Ontario and to validate the extent to which health administrative date billing codes accurately represent MSK diagnoses. METHODS: De-identified electronic medical records (EMR) from the DELPHI database in southwestern Ontario, which contains 2493 patients (55.6% female, mean age 50.3 years (SD = 22.2)) and 21,964 encounters (July 1, 2006-June 30, 2010) were used for the analyses. Outcomes included: validation measures of agreement between International Classification of Diseases (ICD-9) diagnostic codes (health administrative data) and International Classification of Primary Care (ICPC) diagnoses defined as the reference standard, time to first ICD-9 code, prevalence, and healthcare utilization. RESULTS: There were 2940 true positive MSK encounters with primary care practitioners for 998 patients. Performance of the ICD-9 diagnostic codes included sensitivity = 76.5%, specificity = 95.2%, PPV = 94.6%, and NPV = 78.7%, compared to the ICPC reference standard. The majority of 998 patients were coded with both an ICPC and ICD-9 MSK code at their first or second encounter (67.4%). However, 23.5% of patients with the ICPC reference standard MSK were never coded with ICD-9. Four-year prevalence of MSK was 52.3% and varied by age (4.5% 0-17 years, 20.1% 18-44, 42.7% 45-64, and 32.7% 65+). Patients at MSK encounters had a higher number of: investigations (17.9% compared to 9.1%, p < .0001); referrals (17.6% compared to 14.3%, p < .0001); and prescriptions for opioids (17.2% compared to 5.3%, p < .0001). CONCLUSIONS: This study determined the prevalence of musculoskeletal conditions in primary care in Ontario using a reference standard definition. The study highlighted the value of using primary care ICPC codes to validate a definition for musculoskeletal conditions. Health administrative data can be used to ascertain the presence of musculoskeletal conditions; however, ICD-9 codes may underrepresent the prevalence of MSK conditions.

Psychosocial diagnoses occurring after patients present with fatigue.

OBJECTIVE: To discover the frequency of psychosocial and other diagnoses occurring at the end of a visit when patients present to their FPs with concerns about fatigue. DESIGN: Cross-sectional study of patient-FP encounters for fatigue. SETTING: Ten FP practices in southwestern Ontario. PARTICIPANTS: A total of 259 encounters involving 167 patients presenting to their FPs between March 1, 2006, and June 30, 2010, with concerns about fatigue. MAIN OUTCOME MEASURES: The frequency of psychological and social diagnoses made at the end of visits, and whether diagnoses were made by FPs at the end of the visits versus whether the code for fatigue remained. The associations between patient age, sex, fatigue presenting with other symptoms, or the presence of previous chronic conditions and the outcomes was tested. RESULTS: Psychosocial diagnoses were made 23.9% of the time. Among psychosocial diagnoses made, depressive disorder and anxiety disorder or anxiety state were diagnosed more often in women (P = .048). Slightly less than 30% of the time, the cause of patients' fatigue remained undiagnosed at the end of the encounter. A diagnosis was made more often in men. CONCLUSION: Causes of fatigue frequently remain undiagnosed; however, when there is a diagnosis, psychosocial diagnoses are common. Therefore, it would be appropriate for FPs to screen for psychosocial issues when their patients present with fatigue, unless some other diagnosis is evident. Depression and anxiety could be considered particularly among female patients with fatigue.

Comparisons of multi-morbidity in family practice--issues and biases.

BACKGROUND: As the population ages, practice and policy need to be guided by accurate estimates of chronic disease burden in primary care. OBJECTIVE: To produce a preliminary set of methodological considerations for cross-sectional and retrospective cohort studies of multi-morbidity in primary care using three studies as examples. Prevalence rate results from the three studies were re-estimated using identical age-sex groups. METHODS: We compared the methods and results of three separate studies in primary care: (i) patients in the Saguenay region of Quebec, Canada (2005); (ii) a substudy of the BEACH (Bettering the Evaluation and Care of Health) programme in Australia (2008); and (iii) the DELPHI (Deliver Primary Health Care Information) project in South-western Ontario, Canada (2009). Areas where the methods of multi-morbidity studies may differ were identified. The percentage of patients with two or more chronic conditions was compared by age-sex groups. RESULTS: Multi-morbidity prevalence varied by as much as 61%, where reported prevalence was 95% among females aged 45-64 in the Saguenay study, 46% in the BEACH substudy and 34% in the DELPHI study. Several aspects of the methods and study designs were identified as differing among the studies, including the sampling of frequent attenders, sampling period, source of data, and both the definition and count of chronic conditions. CONCLUSIONS: Understanding the differences among the methods used to produce prevalence data on multi-morbidity in primary care can help explain the varying results. Standardization of methods would allow for more valid inter-study comparisons.

The sum of the parts detracts from the intended whole: competencies and in-training assessments.

OBJECTIVES: Despite the fact that Canadian residency programmes are required to assess trainees' performance within the context of the CanMEDS Roles Framework, there has been no inquiry into the potential relationship between residents' perceptions of the framework and their in-training assessments (ITA). Using data collected during the study of ITA, we explored residents' perceptions of these competencies. METHODS: From May 2006-07, a purposive sample of 20 resident doctors from internal medicine, paediatrics, and surgery were interviewed about their ITA experiences. Data collection and analysis proceeded in an iterative fashion consistent with grounded theory. In April 2008, a summary of recurrent themes was presented during a focus group interview of another five residents to afford further elaboration and refinement of thematic findings. RESULTS: The in-training assessment report (ITAR) was perceived as a primary source of residents' information on CanMEDS. Residents' familiarity with the set of competencies appeared to be quite limited and they possessed narrow definitions of the roles. Several trainees questioned the framework's relevance and some appeared confused about the overlapping nature of the roles. Although residents viewed the central Medical Expert role as the most relevant and important competency, they incorrectly perceived it as only involving the acquisition of medical and scientific knowledge. A visual rhetorical analysis of a typical ITAR suggests that the visual features found within this assessment tool may be misrepresenting the framework and the centrality of the Medical Expert role. CONCLUSIONS: Resident doctors' knowledge of CanMEDS was found to be limited. The visual structure of the ITAR appears to be a factor in residents' apparent distortion of the CanMEDS construct from its original holistic philosophy.

Rules of engagement: residents' perceptions of the in-training evaluation process.

BACKGROUND: In-training evaluation reports (ITERs) often fall short of their goals of promoting resident learning and development. Efforts to address this problem through faculty development and assessment-instrument modification have been disappointing. The authors explored residents' experiences and perceptions of the ITER process to gain insight into why the process succeeds or fails. METHOD: Using a grounded theory approach, semistructured interviews were conducted with 20 residents. Constant comparative analysis for emergent themes was conducted. RESULTS: All residents identified aspects of "engagement" in the ITER process as the dominant influence on the success of ITERs. Both external (evaluator-driven, such as evaluator credibility) and internal (resident-driven, such as self-assessment) influences on engagement were elaborated. When engagement was lacking, residents viewed the ITER process as inauthentic. CONCLUSIONS: Engagement is a critical factor to consider when seeking to improve ITER use. Our articulation of external and internal influences on engagement provides a starting point for targeted interventions.
