How to Effectively Implement an Indicator System to Improve Performance from a Management Perspective: The Case of Taiwan Healthcare Indicator Series (THIS) System

This study uses the Taiwan Healthcare Indicator Series (THIS) system as an example to examine which determinants would improve performance by sharing indicators from a management perspective. This study population included all 227 hospitals participating in the THIS system in 2006. A structured questionnaire was sent to the director who was responsible for the THIS system via electronic mail. A total of 111 responses were returned by February 10, 2006. Questions included current implementation and impacts of the system. Hierarchical regression models were performed to identify which variables were significantly associated with performance improvement, adjusted for hospital characteristics. Four variables significantly associated with implementing the THIS system to improve performance were ‘senior management support,’ ‘benchmarking,’ ‘making departments improve the underperforming indicators and report the improvement results in performance management meetings,’ and ‘integration with the National Health Insurance payment regulations’. This study contributes substantially to the evidence base about what works to improve performance by information sharing. Although information sharing is the basis of efforts to improve performance, senior management support and how to effectively apply the information are the most important determinants of performance enhancement.     

Clinical and genetic characteristics of Stargardt disease in a large Western China cohort: Report 1

Stargardt disease 1 (STGD1) is the most prevalent retinal dystrophy caused by pathogenic biallelic ABCA4 variants. Forty‐two unrelated patients mostly originating from Western China were recruited. Comprehensive ophthalmological examinations, including visual acuity measurements (subjective function), fundus autofluorescence (retinal imaging), and full‐field electroretinography (objective function), were performed. Next‐generation sequencing (target/whole exome) and direct sequencing were conducted. Genotype grouping was performed based on the presence of deleterious variants. The median age of onset/age was 10.0 (5–52)/29.5 (12–72) years, and the median visual acuity in the right/left eye was 1.30 (0.15–2.28)/1.30 (0.15–2.28) in the logarithm of the minimum angle of resolution unit. Ten patients (10/38, 27.0%) showed confined macular dysfunction, and 27 (27/37, 73.7%) had generalized retinal dysfunction. Fifty‐eight pathogenic/likely pathogenic ABCA4 variants, including 14 novel variants, were identified. Eight patients (8/35, 22.8%) harbored multiple deleterious variants, and 17 (17/35, 48.6%) had a single deleterious variant. Significant associations were revealed between subjective functional, retinal imaging, and objective functional groups, identifying a significant genotype–phenotype association. This study illustrates a large phenotypic/genotypic spectrum in a large well‐characterized STGD1 cohort. A distinct genetic background of the Chinese population from the Caucasian population was identified; meanwhile, a genotype–phenotype association was similarly represented.     

Clinical results of arthroscopic rotator cuff repair in diabetic and non-diabetic patients

BackgroundAlthough the clinical outcomes of arthroscopic rotator cuff repair (ARCR) have been reported, few studies have focused on diabetic patients. We investigated and compared the clinical results of ARCR in patients with and without diabetes.MethodsThis retrospective study involved 195 consecutive patients who underwent ARCR from 2015 to 2018 in our hospital. Twenty-seven and 168 shoulders were assigned to diabetes and non-diabetes groups, respectively. Diabetic patients with poor control were preoperatively hospitalized for perioperative diabetic control. We evaluated range of motion (ROM), Japanese Orthopaedic Association shoulder (JOA) score, Constant Shoulder Score, and University of California, Los Angeles (UCLA) score preoperatively and at 6 months and 1 year post-ARCR. Rates of rotator cuff retear 1 year post-ARCR and preoperative and postoperative stiff shoulder were also evaluated. We compared the results between groups and analyzed them statistically. A p-value of <0.05 was considered statistically significant.ResultsPreoperative ROM, JOA score, Constant Shoulder Score and UCLA scores showed significant improvement at post-ARCR in both groups (p < 0.05). On comparing the groups, although preoperative JOA score and Constant Shoulder Score were significantly lower in diabetes group than in non-diabetes group (diabetic/non-diabetic group; 60.0/65.3 for JOA score; p = 0.003, 59.7/64.2 for Constant Shoulder Score; p = 0.003), there was no significant difference postoperatively (6 months post-ARCR; 88.0/89.7 for JOA score; p = 0.783, 88.1/88.6 for Constant Shoulder Score; p = 0.597, 1 year post-ARCR; 96.7/95.4 for JOA score; p = 0.238, 96.6/95.4 for Constant Shoulder Score; p = 0.248). Furthermore, preoperative and postoperative stiff shoulder and retear rates were not significantly different between groups (p = 0.152, p = 0.344, p = 0.347, and p = 0.563, respectively).ConclusionDiabetic patients showed comparable clinical results with non-diabetic patients post-ARCR. Perioperative diabetic control may be recommended for preoperatively uncontrolled diabetic patients.     

Characteristics of hidden blood loss following hybrid total knee arthroplasty

BackgroundHidden blood loss (HBL) unrecognized by the usual practice of assessing intraoperative loss and postoperative drainage comprises a considerable proportion of total blood loss (TBL) during primary total knee arthroplasty (TKA). However, HBL has not been adequately investigated in hybrid TKA (uncemented femur, cemented tibia). The purpose of this study was to clarify the amount and influential factors of HBL in hybrid TKA.MethodsA consecutive series of 151 knees in 137 patients with knee osteoarthritis who underwent hybrid TKA were retrospectively evaluated. We examined the correlations between HBL and various factors of concern for their effects on TBL, including age, sex, body weight (BW), body height, body mass index, operation time, tourniquet time, and visible blood loss (VBL) in three periods (intraoperative: VBL₁; until 3 h postoperatively: VBL₂; from 3 h to 1 day postoperatively: VBL₃).ResultsMedian (interquartile range) HBL and TBL were 528 (388, 711) mL and 725 (582, 926) mL, respectively. HBL relative to TBL (H/T) was 73%. There were weak correlations between HBL and BW (r = 0.249, p = 0.002) and between HBL and VBL₃ (r = −0.261, p = 0.001). Multivariate analyses confirmed a positive correlation between HBL and BW (β = 0.296, p < 0.001) and a negative correlation between HBL and VBL₃ (β = −0.270, p < 0.001).ConclusionsHybrid TKA showed comparable values of HBL and H/T to those reported for cemented TKA. Therefore, management strategies for HBL in hybrid TKA can follow the same protocols used for cemented TKA. High BW and low VBL₃ may be predictors of postoperative HBL in hybrid TKA.     

Saltwater fish but not freshwater fish consumption is positively related to handgrip strength: The TCLSIH Cohort Study

Fish contain many important nutrients and are primarily known for high n-3 polyunsaturated fatty acids (n-3 PUFA) content. Studies have shown that supplementation of fish oil-derived n-3 PUFA improves muscle mass and strength. Here, we hypothesized that fish consumption might improve muscle strength. To test this hypothesis, we performed this cross-sectional study (n = 29,084) in Tianjin, China. The frequency of fish consumption was assessed using a valid self-administered food frequency questionnaire. Handgrip strength (HGS) was used as the indicator of muscle strength, and was measured using a handheld digital dynamometer. Analysis of covariance was used to examine the relationship between fish consumption and HGS. In men, after adjusted potential confounding factors, the least square means (95% confidence intervals) of HGS across saltwater fish consumption categories were 41.5 (41.1, 43.7) kg for <1 time/week, 44.6 (43.2, 45.8) kg for 1 time/week, and 44.7 (43.3, 46.1) kg for ≥2 to 3 times/week (P for trend <0.001). In men, the least square means (95% confidence intervals) of HGS across the ascending quartiles of dietary n-3 PUFA intake were 43.6 (43.2, 44.4) kg, 43.7 (43.2, 44.6) kg, 44.4 (43.0, 45.8) kg, and 44.6 (43.1, 46.0) kg (P for trend <0.01). The results showed that saltwater fish consumption was positively related to HGS in men, but not in women, suggesting that saltwater fish contain nutrients that may be used to improve HGS.     

Dry Chemistry Instruments in Primary Care. I. Operating Conditions and Financial Considerations

The objectives of this study were to describe the operatingconditions of dry chemistry instruments in primary care, aswell as to elucidate financial aspects in general practice fee-for-servicesettings. We used questionnaires mailed to all users of thetwo most used dry chemistry instruments in Norway, as well asto a 14% random sample of Norwegian GPs. The overall responserate was 79%. The mean number of dry chemistry analyses variedconsiderably between individual users, but in general a substantialnumber of analyses were carried out. Even though most analyseson the instruments' repertoire were available in all user groups,a total of 13 additional constituents were suggested to be includedin the repertoire. In occupational health care most resultswere ready when the client was present; this was not the casein general practice. The instruments were more profitable whenmore constituents were analysed per sample, although profitabilityvaried substantially in the period studied (1986–1989).A discrete time history event analysis revealed that net profitearned, lower instrument price, available information aboutthe technology and being in solo practice significantly influencedthe decision to buy an instrument in fee-for- service practices.     

International Nonproprietary Names (INN) for pharmaceutical substances.

WHO has a constitutional mandate to "develop, establish and promote international standards with respect to biological, pharmaceutical and similar products". The Organization collaborates closely with national nomenclature committees to select a single name of worldwide acceptability for each active substance that is to be marketed as a pharmaceutical. To avoid confusion, which could jeopardize the safety of patients, trade-marks should neither be derived from INNs nor contain common stems used in INNs. Recent developments in pharmacological research and biotechnology are challenges for the nomenclature committee. New schemes and concepts are being developed, for example, for naming monoclonal antibodies and other recombinant compounds.
