Economic Evaluation of Novel Models of Care for Patients With Acute Medical Problems.

Importance: During COVID-19, Singapore simultaneously experienced a dengue outbreak, and acute hospitals were under pressure to lower bed occupancy rates. This led to new models of care to treat patients with acute, low-severity medical conditions either at home, in a hospital-at-home (HaH) model, or in a clinic-style setting sited at the emergency department in an ambulatory care team (ACT) model, but a reliable cost analysis for these models is lacking. Objective: To compare personnel costs of HaH and ACT with inpatient care. Design, Setting, and Participants: In this economic evaluation study, time-driven activity-based costing was used to compare the personnel cost of inpatient care with treating dengue via HaH and treating chest pain via ACT. Participants were patients with nonsevere dengue and chest pain unrelated to a coronary event admitted via the emergency department to the internal medicine service of a tertiary hospital in Singapore. Exposures: HaH for dengue and ACT for chest pain. Main Outcomes and Measures: A process map was created for the patient journey for a typical patient with each condition. The amount of time personnel spent on delivering care was estimated and the cost per minute determined based on their wages in 2022. The total cost of care was calculated by multiplying the time spent by the per-minute cost of the personnel resource and summing all costs. Results: Compared with inpatient care, HaH used 50% less nursing time (418 minutes, 95% uncertainty interval [UI], 370 to 465 minutes) but 80% more medical time (303 minutes, 95% UI, 270 to 338 minutes) per case of dengue. If implemented nationally, HaH would save an estimated 56 828 SGD per year (95% UI, -169 497 to 281 412 SGD [US $41 856; 95% UI, -$124 839 to $207 268]). The probability that HaH is cost saving was 69.2%. Compared with inpatient care, ACT used 15% less nursing time (296 minutes, 95% UI, 257 to 335 minutes) and 50% less medical time (57 minutes, 95% UI, 46 to 69 minutes) per case of chest pain. If implemented nationally, ACT would save an estimated 1 561 185 SGD per year (95% UI, 1 040 666 to 2 086 518 SGD [US $1 149 862; 95% UI, $766 483 to $1 536 786]). The probability that ACT is cost saving was 100%. Conclusions and Relevance: This economic evaluation found that the HaH and ACT models decreased the overall personnel cost of care. Reorganizing hospital resources may help hospitals reap the benefits of reduced hospital-acquired infections, improved patient recovery, and reduced hospital bed occupancy rates.

Gender Differences in Knowledge, Attitudes and Practices towards Cardiovascular Disease and its Treatment among Asian Patients.

Introduction: Knowledge, attitudes and practices (KAP) impact on cardiac disease outcomes, with noted cultural and gender differences. In this Asian cohort, we aimed to analyse the KAP of patients towards cardiac diseases and pertinent factors that influence such behaviour, focusing on gender differences. Materials and Methods: A cross-sectional survey was performed among consecutive outpatients from a cardiac clinic over 2 months in 2014. Results: Of 1406 patients approached, 1000 (71.1%) responded (mean age 57.0 ± 12.7 years, 713 [71.3%] males). There was significant correlation between knowledge and attitude scores (r = 0.224, P <0.001), and knowledge and practice scores (r = 0.114, P <0.001). There was no correlation between attitude and practice scores. Multivariate predictors of higher knowledge scores included female sex, higher education, higher attitude and practice scores and prior coronary artery disease. Multivariate predictors of higher attitude scores included higher education, higher knowledge scores and non-Indian ethnicity. Multivariate predictors of higher practice scores included male sex, Indian ethnicity, older age, higher knowledge score and hypertension. Males had lower knowledge scores (85.8 ± 8.0% vs 88.0 ± 8.2%, P <0.001), lower attitude scores (91.4 ± 9.4% vs 93.2 ± 8.3%, P = 0.005) and higher practice scores (58.4 ± 18.7% vs 55.1 ± 19.3%, P = 0.013) than females. Conclusion: In our Asian cohort, knowledge of cardiovascular health plays a significant role in influencing attitudes and practices. There exists significant gender differences in KAP. Adopting gender-specific strategies for future public health campaigns could address the above gender differences.

Complementary and alternative medicine use amongst patients with cardiovascular disease in Singapore.

BACKGROUND: Data on complementary and alternative medicine (CAM) use in patients with cardiovascular disease (CVD) are lacking. We aim to investigate the prevalence of CAM use among patients with CVD attending a tertiary centre for cardiovascular care, their attitudes and beliefs towards CAM, and factors associated with CAM usage. METHODS: A cross-sectional, self-administered written survey was conducted on consecutive patients attending outpatient cardiovascular clinics at our tertiary institution over 2 months from June to July 2014. Information gathered included demographic data and various aspects of CAM use. RESULTS: A total of 768 responses (562 males, mean age 57 ± 13 years, 74 % Chinese, 6 % Malay, 14 % Indian) were included. The prevalence of CAM use in the cohort was 43.4 % (333/768). Biologically-based systems (29.4 %) was the most common type of CAM used. Some patients (19.0 %) used multiple types of CAM simultaneously. External influences (78.1 %) were cited more than internal influences (47.8 %) to affect CAM use. Malay ethnicity (compared to Chinese) was the only significant negative multivariate predictor of CAM use (OR = 0.531 (95 % CI 0.147 to 0.838), p = 0.018). A significantly higher proportion of CAM users compared to non-CAM users were non-compliant to medications (35.6 %, n = 114 vs. 20.5 %, n = 84, p < 0.001) and consults (41.4 %, n = 130 vs. 28.1 %, n = 112, p < 0.001) respectively. CONCLUSION: The usage of CAM is prevalent amongst our patients with CVD. CAM use was associated with poorer reported compliance to medications and consults. Understanding the factors influencing CAM use amongst CVD patients provides medical professionals with an opportunity to better discuss CAM use and potentially enhance the patient-physician interaction.

Black bone disease in a healing fracture.

Black bone disease refers to the hyperpigmentation of bone secondary to prolonged usage of minocycline. We present a report of a 34-year-old man who underwent femoral shaft fracture fixation complicated by deep infection requiring debridement. The implants were removed 10 months later after long-term treatment with minocycline and fracture union. A refracture of the femoral shaft occurred 2 days after implant removal and repeat fixation was required. Intraoperatively, abundant heavily pigmented and dark brown bone callus was noted over the old fracture site. There was no evidence of other bony pathology and the appearance was consistent with minocycline-associated pigmentation. As far as we are aware, this is the first case of black bone disease affecting callus within the interval period of bone healing. We also discuss the relevant literature on black bone disease to bring light on this rare entity that is an unwelcomed surprise to operating orthopaedic surgeons.
