An Outreach Rehabilitation Program for Nursing Home Residents After Hip Fracture May Be Cost-Saving.

BACKGROUND: We compared the cost-effectiveness of 10 weeks of outreach rehabilitation (intervention) versus usual care (control) for ambulatory nursing home residents after hip fracture. METHODS: Enrollment occurred February 2011 through June 2015 in a Canadian metropolitan region. Seventy-seven participants were allocated in a 2:1 ratio to receive a 10-week rehabilitation program (intervention) or usual care (control) (46 intervention; 31 control). Using a payer perspective, we performed main and sensitivity analyses. Health outcome was measured by quality-adjusted life years (QALYs), using the EQ5D, completed at study entry, 3-, 6-, and 12-months. We obtained patient-specific data for outpatient visits, physician claims, and inpatient readmissions; the trial provided rehabilitation utilization/cost data. We estimated incremental cost and incremental effectiveness. RESULTS: Groups were similar at study entry; the mean age was 87.9 ± 6.6 years, 54 (71%) were female and 58 (75%) had severe cognitive impairment. EQ5D QALYs scores were nonsignificantly higher for intervention participants. Inpatient readmissions were two times higher among controls, with a cost difference of -$3,350/patient for intervention participants, offsetting the cost/intervention participant of $2,300 for the outreach rehabilitation. The adjusted incremental QALYs/patient difference was 0.024 favoring the intervention, with an incremental cost/patient of -$621 for intervention participants; these values were not statistically significant. A sensitivity analysis reinforced these findings, suggesting that the intervention was likely dominant. CONCLUSION: A 10-week outreach rehabilitation intervention for nursing home residents who sustain a hip fracture may be cost-saving, through reduced postfracture hospital readmissions. These results support further work to evaluate postfracture rehabilitation for nursing home residents.

Cost-Effectiveness Evaluation of Collaborative Care for Diabetes and Depression in Primary Care.

INTRODUCTION: Information is limited on the cost effectiveness of strategies to improve depressive symptoms in patients with Type 2 diabetes in primary care outside of the U.S. METHODS: Using patient data from a 12-month controlled implementation trial, outcomes and healthcare costs determined through administrative database linkages were compared for a strategy of family physician notification and follow-up ("enhanced care") versus collaborative care. Two measures of effectiveness were used: depression-free days (DFDs) based on Patient Health Questionnaire, and quality-adjusted life years (QALYs) based on EQ-5D. Data were collected November 2010 to January 2013 with analyses completed in May 2015. Incremental cost-effectiveness ratios were also compared against true usual care patients. RESULTS: Among 227 patients, mean age was 58 years, 55% were female, and mean diabetes duration was 12 years. Compared with total 12-month cost per usual care patient (C$5,889), the incremental cost was C$450 for patients in enhanced care and C$1,021 for collaborative care. Both enhanced and collaborative care strategies improved outcomes compared with usual care, with incremental DFDs of 65.9 and 117.6, and incremental QALYs of 0.006 and 0.042, respectively. Compared with enhanced care, collaborative care yielded incremental cost-effectiveness ratios of C$11/DFD and C$15,861/QALY. Compared with usual care, the incremental cost-effectiveness ratios were C$7/DFD or C$76,271/QALY for enhanced care and C$9/DFD or C$24,368/QALY for collaborative care. CONCLUSIONS: In primary care patients with Type 2 diabetes who screened positive for depression, physician notification and follow-up was a clinically effective strategy compared with usual care, but investing more resources in collaborative care yielded the most cost-effective strategy.

Transobturator tape versus retropubic tension-free vaginal tape for stress urinary incontinence: 5-year safety and effectiveness outcomes following a randomised trial.

INTRODUCTION AND HYPOTHESIS: In a randomised trial comparing transobturator tape (TOT) to retropubic tension-free vaginal tape (TVT) for women with stress urinary incontinence (SUI), vaginal examination at 12 months showed that tapes were palpable for 80.0 % of the TOT group versus 26.7 % of the TVT group. We hypothesized that this difference would lead to more women in the TOT group experiencing vaginal mesh erosion or other serious adverse events compared to women in the TVT group 5 years after surgery. METHODS: All participants were invited to join the follow-up study after being randomised to receive TOT or TVT for SUI. Consenting women had a vaginal examination, a pad test for urinary incontinence (UI) and completed Health-related Quality of Life Questionnaires (HRQOL). Women unable to attend the clinic completed questionnaires only. The primary composite outcome incorporated mesh exposure, urinary retention, repeat incontinence surgery and moderate to severe pelvic pain. Assuming 80 % follow-up, our study would have 67 % power to detect a difference in primary outcome (two-sided 5 % level of significance). Comparisons between groups used chi-square tests and t tests. RESULTS: One hundred and seventy-six (88.4 %) women participated in the 5-year follow-up (83 TOT, 93 TVT). The primary composite outcome occurred in 21.8 % of the TOT and 27.6 % of the TVT groups [difference =-5.8 %, 95 % confidence interval (CI) -18.9 % to 7.3 %, p value 0.39)] Vaginal examination found more women with palpable tapes in the TOT versus the TVT group (48.5 % versus 22.4 %, p value 0.001). There were no other significant differences between groups. CONCLUSIONS: Serious adverse events and tape effectiveness did not differ between groups at 5 years. Palpable tape remains a concern for women who receive TOT for treating SUI.

Surgical management of stress urinary incontinence in women: safety, effectiveness and cost-utility of trans-obturator tape (TOT) versus tension-free vaginal tape (TVT) five years after a randomized surgical trial.

BACKGROUND: We recently completed a randomized clinical trial of two minimally invasive surgical procedures for stress urinary incontinence, the retropubic tension-free vaginal tape (TVT) versus the trans-obturator tape (TOT) procedure. At one year postoperatively, we were concerned to find that a significant number of women had tape that was palpable when a vaginal examination was undertaken. Because the risk factors for adverse outcomes of tape surgery are not clearly understood, we are unable to say whether palpable tapes will lead to vaginal erosions or whether they merge into vaginal tissue. We do not know whether patients go on to have further adverse consequences of surgery, leading to additional cost to patients and healthcare system. Our current study is a 5 year follow-up of the women who took part in our original trial. METHODS/DESIGN: All 199 women who participated in our original trial will be contacted and invited to take part in the follow-up study. Consenting women will attend a clinic visit where they will have a physical examination to identify vaginal erosion or other serious adverse outcomes of surgery, undertake a standardized pad test for urinary incontinence, and complete several health-related quality of life questionnaires (15D, UDI-6, IIQ-7). Analyses will compare the outcomes for women in the TOT versus TVT groups. The cost-effectiveness of TOT versus TVT over the 5 years after surgery, will be assessed with the use of disease-specific health service administrative data and an objective health outcome measure. A cost-utility analysis may also be undertaken, based on economic modeling, data from the clinical trial and inputs obtained from published literature. DISCUSSION: This study is needed now, because TOT and TVT are among the most frequently conducted surgical procedures for stress urinary incontinence in Canada. Because stress urinary incontinence is so common, the impact of selecting an approach that causes more adverse events, or is less effective, will have a significant impact on individual quality of life, and societal and health care costs.

Transobturator tape compared with tension-free vaginal tape for stress incontinence: a randomized controlled trial.

OBJECTIVE: To compare the effectiveness of transobturator tape with tension-free vaginal tape (TVT) in terms of objective cure of stress urinary incontinence (SUI) at 12 months postoperatively. METHOD: Women with SUI were randomly allocated to either transobturator tape or TVT procedures and reviewed at 12 months after surgery. The primary outcome was objective evidence of "cure," evaluated by standardized pad test (cure defined as less than 1 g urine leaked). Other outcomes included complications, subjective cure, incontinence-related quality of life, return to usual sexual activity, and satisfaction with surgery. Primary analysis compared the proportion of patients in each group who were cured at 12-month follow-up. RESULTS: A total of 199 women participated (94 in the transobturator tape group, 105 in the TVT group). Sixty-eight women (81%) in the transobturator tape group were cured, compared with 67 (77%) in the TVT group (relative risk 1.05, 95% confidence interval 0.90-1.23, P=.577). On vaginal examination, the tape was palpable for 68 women (80%) in the transobturator tape group and for 24 (27%) in the TVT group (relative risk 0.22, 95% confidence interval 0.13-0.37, P<.001). More women in the transobturator tape group experienced groin pain during vaginal palpation (13 [15%] in the transobturator tape group and five [6%] in the TVT group, P=.044). Quality of life improved significantly from baseline in both groups (30-point improvement in IIQ-7 score for both groups). CONCLUSION: At 12 months, the majority of women had minimal leakage and their quality of life had improved significantly, but differences were not observed between groups. The presence of palpable tape, particularly among the transobturator tape group, is concerning; longer follow-up is needed to determine whether this outcome leads to extrusion or resolves over time.

The effect of a preoperative exercise and education program on functional recovery, health related quality of life, and health service utilization following primary total knee arthroplasty.

OBJECTIVE: To determine the effectiveness of a preoperative exercise/education program on functional recovery, health related quality of life (HRQOL), health service utilization, and costs following primary total knee arthroplasty (TKA). METHODS: One hundred thirty-one subjects were randomized to either the control (n = 66) or treatment (n = 65) group 6 weeks before TKA surgery. Patients in the treatment group underwent a 4-week exercise/education program before surgery. All subjects were assessed 6 weeks preoperatively (before the exercise/education intervention), immediately preoperatively (after the exercise/education intervention), and 3, 6 and 12 months after surgery utilizing the Western Ontario McMaster Osteoarthritis Index, the SF-36, and knee range of motion (ROM) and strength measures. Data on length of stay, numbers of community rehabilitation or homecare visits following discharge from the surgical hospital, and the costs associated with these services were also collected. RESULTS: Subjects were similar in demographic characteristics and all measurements at the baseline assessment. No differences were seen in knee measurements (ROM and strength), pain, function, or HRQOL between the 2 groups following the intervention program or at any postoperative measurement point. Patients in the treatment group used fewer postoperative rehabilitation services and stayed for a shorter time in hospital than the control group, but these differences did not attain statistical significance. CONCLUSION: The exercise/education intervention did not alter functional recovery or HRQOL following TKA. Health service utilization was less in the treatment group, but our study was underpowered to attain statistical significance for these measures.

Effect of adjunctive range-of-motion therapy after primary total knee arthroplasty on the use of health services after hospital discharge.

INTRODUCTION: There is controversy as to whether continuous passive motion (CPM) after total knee arthroplasty (TKA), which is the standard treatment, confers significant benefit with respect to outcome. The primary purpose of this study was to determine if CPM or slider-board (SB) therapy, used as adjuncts to standardized exercises (SEs) during the acute-care hospital stay, resulted in a reduced total length of hospitalization and post-discharge rehabilitation in patients who underwent primary TKA. METHODS: We carried out a randomized, clinical trial on 120 patients who received a TKA at the University of Alberta Hospital, Edmonton, a tertiary care institution. The study horizon began at the point of discharge from the hospital and continued up to 6 months after operation. Postoperatively, patients (40 in each group) received CPM and SEs, SB therapy and SEs or SEs alone while in the tertiary Health service use was compared using transfer institution length of stay(LOS), post-discharge rehabilitation, readmission and complication rates and their associated costs. RESULTS: There were no differences in health service use or costs among the 3 groups over the 6-month study. The rates of postoperative complications and readmissions also were similar among the groups. Increased health service use associated with knee flexion that was less than 60 degrees at discharge, but similar proportions of patients with poor knee range of movement (ROM) at discharge were found in each group. CONCLUSIONS: This finding suggests that adjunctive ROM therapy, as used in this study, does not reduce health service use. Further research is required to determine if adjunctive ROM therapy after discharge from the surgical hospital decreases health service utilization in those patients who have poor knee ROM at the time of discharge.
