RESUMEN
Importance: The effects of self-administered acupressure (SAA) on knee osteoarthritis (OA) pain remain unclear. Objective: To evaluate the effectiveness of SAA taught via a short training course on reducing knee OA pain in middle-aged and older adults. Design, Setting, and Participants: This randomized clinical trial was conducted among community-dwelling individuals in Hong Kong who were aged 50 years or older with probable knee OA from September 2019 to May 2022. Interventions: The intervention included 2 training sessions for SAA with a brief knee health education (KHE) session, in which participants practiced acupressure twice daily for 12 weeks. The control group (KHE only) received only education about maintaining knee health on the same schedule and duration. Main Outcomes and Measures: The primary outcome was the numerical rating scale (NRS) pain score at 12 weeks. Other outcomes included Western Ontario and McMaster University Osteoarthritis Index, Short Form 6 Dimensions (SF-6D), Timed Up and Go, and Fast Gait Speed tests. Results: A total of 314 participants (mean [SD] age, 62.7 [4.5] years; 246 [78.3%] female; mean [SD] knee pain duration, 7.3 [7.6] years) were randomized into intervention and KHE-only groups (each 157). At week 12, compared with the KHE-only group, the intervention group had a significantly greater reduction in NRS pain score (mean difference [MD], -0.54 points; 95% CI, -0.97 to -0.10 points; P = .02) and higher enhancement in SF-6D utility score (MD, 0.03 points; 95% CI, 0.003 to 0.01 points; P = .03) but did not have significant differences in other outcome measures. The cost-effectiveness acceptability curve demonstrated a greater than 90% probability that the intervention is cost-effective at a willingness to pay threshold of 1 GDP per capita. Conclusions and Relevance: In this randomized clinical trial, SAA with a brief KHE program was efficacious and cost-effective in relieving knee pain and improving mobility in middle-aged and older adults with probable knee OA.

BACKGROUND: Information on HRQOL can enhance patient diagnosis and management but it is rarely available in routine clinical practice. This mixed-method study evaluated the feasibility and acceptability of the electronic EQ-5D-5L measurement of HRQOL in patients with chronic musculoskeletal problems in primary care. METHODS: In three primary care clinics, 665 patients with musculoskeletal problems completed the electronic EQ-5D-5L and Visual Analogue Scale (e-EQ-5D-5L/VAS), and a questionnaire on socio-demographics, perceived ease of use (PEOU), and perceived usefulness (PU) at baseline and two follow-ups. Patient completion and response rates, and time to complete the e-EQ-5D-5L/VAS were measured. During the same consultations, 49 doctors reviewed the e-EQ-5D-5L/VAS reports and completed a clinician questionnaire on PEOU, PU, and time spent to address each report. Individual interviews along with focus group discussions were conducted on patients, doctors, and research assistants for further exploration. RESULTS: Mean completion time reduced from baseline to first and second follow-up (120.66, 83.99, and 105.22 s, respectively). Completion and response rates were high at each follow-up visit (> 99.8% and > 91.11%, respectively). Doctors needed less than 2 min to read the report but felt the time required to address the report was a significant barrier. Some patients had difficulties using e-platforms, in understanding or answering questions; but, PEOU improved with time (p < 0.001). Most patients found the e-platforms useful (> 85.3%). Clinicians agreed a great majority of the reports were easy to use (76.0-85.1%) and useful (69.2-72.0%), particularly aiding with a holistic view of the patient's musculoskeletal problem. CONCLUSION: The e-EQ-5D-5L/VAS is a feasible and acceptable measurement of HRQOL of patients with chronic musculoskeletal problems in routine primary care in Hong Kong which can assist real-time management decisions.

BACKGROUND: Magnetically controlled growing rods (MCGR) have replaced traditional growing rods (TGR) in the past decade, however, a comparison of their direct costs and treatment outcomes based on real longitudinal data is lacking. This study aims to compare the direct cost and treatment outcomes between TGR and MCGR, whilst incorporating complications, reoperations and changes in health-related quality of life (HRQoL) throughout the entire treatment course. METHODS: Patients with early onset scoliosis (EOS) who underwent initial growing rod surgery between 2003 and 2016 at a tertiary scoliosis clinic were studied with longitudinal data. Accumulated direct medical costs were calculated based on the unit cost of surgeries of each TGR and MCGR, costs incurred for any rod exchange or remedial surgery for post-operative complication. Treatment outcomes were evaluated via: Patient's HRQoL using SRS-22r questionnaire, and radiological parameters (including major curve correction, spine length gains, spinal balance) throughout the treatment until maturity. RESULTS: A total of 27 EOS patients (16 MCGR, 11 TGR) were studied. Total direct cost of index surgery for MCGR was HKD$223,108 versus lower cost of HKD$135,184 for TGR (p < 0.001). At 2-3 years post-index surgery, accumulative total direct medical cost of MCGR and TGR became most comparable (TGR:MCGR ratio = 1.010) and had reached neutrality between the two groups since. Radiological parameters had no intergroup differences at maturity. For HRQoL, TGR group had shown the trend of less pain (domain score mean difference: 0.53, p = 0.024) post-index surgery and better self-appearance (domain score mean difference: 1.08, p = 0.017) before fusion. Higher satisfaction with treatment (domain score mean difference: 0.76, p = 0.029) was demonstrated by TGR patients at fusion/maturity. MCGR had negative (rs = -0.693) versus TGR's positive (rs = 0.989) correlations (p < 0.05) of cost and SRS-22r total scores at 2-3 years post-index surgery. CONCLUSIONS: From index surgery to maturity, TGR demonstrated better satisfaction with treatment by patients and comparable overall HRQoL with MCGR during the treatment course, as MCGR did not show apparent benefit despite less surgeries and cost neutrality between the two groups at 2-3 years post-index surgery.

BACKGROUND: Postoperative pain following laparotomy for gynaecological diseases is a common problem that requires effective management to ensure patient satisfaction and recovery. Despite the wide use of acupuncture for pain management, knowledge of its efficacy in managing postoperative pain is limited. Previous literature used either acupuncture or auricular acupuncture alone. However, the combined use of acupuncture and auricular acupuncture have not been studied yet. PURPOSE: This study examined the efficacy and feasibility of combined electroacupuncture and auricular acupuncture compared to a sham control in reducing pain during 5 days after a laparotomy for gynaecological diseases. This combined therapy was hypothesized to provide greater pain reduction than previous studies with less frequent treatment. STUDY DESIGN: Randomized sham-controlled, patient- and- assessor-blinded trial. METHODS: This trial recruited 72 patients scheduled for laparotomy in Hong Kong. Either acupuncture (n = 36) or non-invasive sham acupuncture (n = 36) was performed on the patients preoperatively (1 session) and postoperatively (once a day, up to 6 sessions). The primary outcome was pain at rest, measured using a numerical rating scale from postoperative days 0-5. Secondary outcomes such as analgesics consumption were also assessed. A data and safety monitoring board (DSMB) was established. RESULTS: All 72 randomized patients were included in the analysis. The acupuncture group had a smaller pain score at rest at 22 hrs (mean = 2.6) than the sham control group (mean = 4.0) (Post hoc intention to treat analysis, Linear regression, mean difference = -1.4, 95% confidence interval = [-0.2] -2.7, p = 0.029). No statistically significant between-group difference was found in other outcomes. No serious adverse event was observed. CONCLUSION: Perioperative acupuncture treatments are safe and feasible, but the efficacy of acupuncture is inconclusive.

BACKGROUND: Patient enablement is a core tenet of patient-centred and holistic primary care. The Patient Enablement Instrument (PEI) is a transitional measure limited in its ability to measure changes over time. A modified version, PEI-2, has been developed to measure enablement at a given time-point without comparison to a recalled baseline. OBJECTIVE: To assess the validity, reliability, sensitivity and responsiveness of PEI-2. METHODS: PEI-2 was modified from the Chinese PEI to assess enablement over 4 weeks in a prospective cohort study nested within a community support programme [Trekkers Family Enhancement Scheme (TFES)] in Hong Kong. Construct validity was assessed by factor analysis and convergent validity by Spearman's correlations with health-related quality of life and depressive symptoms. Internal reliability was assessed using Cronbach's alpha. Test-retest reliability was assessed by intraclass correlation (ICC), responsiveness by 12-24-month change in PEI-2 score and sensitivity by differences in change of PEI-2 score between TFES participants and a control group. RESULTS: PEI-2 demonstrated construct validity with all items loading on one factor (factor loadings >0.7). Convergent validity was confirmed by significant correlations with 12-item Short Form Questionnaire, version 2 (r = 0.1089-0.1919) and Patient Health Questionnaire-9 (r = -0.2030). Internal reliability was high (Cronbach's alpha = 0.9095) and test-retest reliability moderate (ICC = 0.520, P = 0.506). Significant improvements in PEI-2 scores among the TFES group suggested good responsiveness (P < 0.001). The difference in change of PEI-2 scores between TFES and control was significant (P = 0.008), indicating good sensitivity. CONCLUSIONS: This study supports the validity, reliability, sensitivity and responsiveness of PEI-2 in measuring changes in enablement, making it a promising tool for evaluating enablement in cohort and intervention studies.

BACKGROUND: Postoperative pain is a major complaint following abdominal surgery for gynecological diseases. Effective postoperative pain control after abdominal surgery is particularly important for patient recovery, mobility, and satisfaction. Acupuncture has been commonly used for pain management. However, its efficacy in postoperative pain control is inconclusive and health economic evaluation is limited. METHODS: A randomized, sham-controlled, patient- and- assessor-blind trial is designed to evaluate the efficacy and safety of acupuncture in managing postoperative pain following abdominal surgery of gynecological diseases. Patients who are eligible for laparotomy with a midline incision for gynecological neoplasia, including ovarian mass, uterine mass, and cervical lesions, will be recruited. Seventy-two participants will be randomly allocated to an acupuncture or non-invasive sham control in a 1:1 ratio. Treatment will be done within 2 h before operation, upon arrival to the ward and once daily for 5 days. The Pain Numerical Rating Scale (NRS) on the first 5 days during hospitalization will be the primary outcome and will be analyzed using the area-under-the-curve (AUC) method. The secondary outcome measures include frequency of rescue analgesic use during hospital stay, cumulative morphine consumption; quality of recovery as measured by time to recovery variables and the Quality of Recovery-9 (QoR-9); quality of life as measured by the Short Form-6 dimension (SF-6D) and EuroQol-5 Dimension-5 Level (EQ-5D-5 L). The incremental cost-effectiveness ratio of acupuncture vs sham acupuncture will be calculated. DISCUSSION: This study protocol provides an example of integrative medicine practice in a hospital setting for the management of postoperative pain using acupuncture treatment. The acupuncture treatment protocol, if proven to be effective, can be implemented in routine settings to play a role in postoperative pain management for patients who have undergone abdominal surgery for gynecological diseases.
